Description:
This invention relates to a machine of the type for applying a coating to a surface such as applying a sealant to asphalt pavement. Such machines are frequently called seal coaters or seal applicators.

Such machines typically include a body including a tank for storing the coating fluid with means for dispensing the coating fluid from the storage tank. They also include some sort of spreading device to spread the coating material over the surface. The machines are supported by wheels, some of which are driven and others of which are steerable. Most seal coating machines of this type in the past are relatively large and provide a seat so that they may be ridden by the operator. All such machines provide some provision whereby the spreading assembly may be raised out of contact with the surface over which the machine is moving. Typical of such prior art machines is that shown in U.S. Pat. No. 3,533,336. Although the machine shown in that patent is an excellent machine, it is particularly adapted for coating relatively large areas and there is not available a suitable smaller machine which may be economically utilized for smaller areas such as driveways and the like.

Accordingly, it is an object and feature of this invention to provide a machine of the type for applying a coating to a surface in an efficient and effective manner when the area of the surface is relatively small.

In correlation with the foregoing object and feature, it is another object and feature of this invention to provide such a machine wherein the spreading means is a rigid part of the body of the machine and is raised and lowered by relative vertical movement between the other end of the body means and one of the wheels.

Other objects and attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

FIG. 1 is a side elevational view of a preferred embodiment of the instant invention showing the machine with the spreader means in the raised position;

FIG. 2 is a side elevational view similar to FIG. 1 but showing the spreader means in the lowered position engaging the surface over which the machine is moving; and

FIG. 3 is a side elevational view similar to FIG. 1 but showing the opposite side of the machine.

Referring now to the drawings wherein like numerals indicate like or corresponding parts throughout the several views, a machine of the type for applying a coating to a surface such as applying a sealant to asphalt pavement is generally shown at 10.

The machine includes a body means generally indicated at 12. The body means 12 includes longitudinally extending channel members or support means 14 which are interconnected by appropriate braces. The body means also includes a reservoir means comprising a tank 16. Also included is a spreader means generally indicated at 18 for distributing fluid over a surface as indicated at 20 in FIG. 2. The tank 16 stores fluid and dispenses the fluid to the spreader means 18.

The machine also includes wheel means comprising a pair of spaced wheels 22 which movably support the body means 12. The wheels 22 are supported by one or more shafts which are connected to the body means 12 through the plates 24. The wheels 22 rotate relative to the body means about the axis of these shafts.

The machine also includes a second wheel means comprising the dirigible wheel generally indicated at 26. The spreader means 18 is disposed on a first side of the axis of rotation of the wheels 20 and the dirigible wheel 26 is disposed on a second side of an axis of rotation of the wheels 22.

The machine further includes positioning means generally indicated at 28 interconnecting the dirigible wheel 26 and the body means 12 for rotating the body means 12 about the axis of rotation of the wheels 22 to vary the vertical position or height of the spreader means 18 above the surface 20 upon which the machine is supported.

The positioning means 28 includes a manually graspable lever arm 30 which is pivotally supported on the tank 16 for movement between an extreme raised position as illustrated in FIGS. 1 and 3, where the spreader means 18 is at a maximum height relative to the surface 20, and an extreme lowered position as illustrated in FIG. 2, where the spreader means 18 is at a minimum height relative to the surface 20.

The positioning means 28 further includes a pair of generally parallel links 32 which are pivotally connected at the first ends thereof to the tank 16, for pivotal movement about horizontal axes, as indicated at 34, and pivotally connected at the second ends thereof to the dirigible wheel 26, for pivotal movement about horizontal axes, as indicated at 36. Preferably the links 32 are flat plate-like members with the lower link 32 rigidly connected to a shaft 38 as shown in FIG. 3. The lever arm 30 is also rigidly connected to the shaft 38 so that upon pivotal movement of the arm 30, the links 32 move between the raised position illustrated in FIGS. 1 and 3 and the lowered position illustrated in FIG. 2.

The dirigible wheel assembly 26 includes a shaft support comprising a plate 40 with a pair of spaced flanges 42 extending perpendicular therefrom so as to be pivotally connected to the links 32. A pair of spaced bearing brackets 44 are connected to the plate 40 and rotatably support a generally vertically disposed steering shaft 46. Thus, the steering shaft 46 is rotatably supported by the shaft support which is in turn pivotally connected at 36 to the links 32. A fork or yoke 48 is attached to the lower end of the shaft 46 and is rotatably connected to the dirigible wheel 50. A steering means comprising a bent extension 52 and a T-bar 54 is connected to the upper end of the shaft 46 for rotating the shaft 46 to steer the machine. As viewed in FIG. 1, the shaft 46 and the dirigible wheel 50 are in the position they would normally be in when the machine is moving to the right as viewed in FIG. 1. As viewed in FIG. 2, the steering shaft 46 is in the position it would normally be in when the machine is moving to the left as viewed in FIG. 2, it being remembered that the machine moves to the left as viewed in FIG. 2 when applying a coating to the surface 20.

A guide means comprising an arcuate plate 56 having a slot therein is secured to one side of the tank 16 for guiding the movement of the lever arm 30. The slot in the plate 56 has an offset portion at the upper arcuate end thereof in which the lever arm 30 may be disposed to retain the lever arm in the position illustrated in FIG. 2 which is the extreme lowered position. This is necessary because when the tank 16 is full of fluid the moment about the axis of rotation of the wheels 22 is such that the machine would tend to move to the position illustrated in FIGS. 1 and 3 if the handle 30 is not maintained in the position illustrated in FIG. 2.

The machine also includes a motor drive means generally indicated at 58. The motor drive means preferably includes a gasoline type internal combustion engine and a hydrostatic transmission. The engine and the transmission are disposed on the opposite extremity of the tank 16 from the dirigible wheel assembly 26 and between the tank 16 and the spreader means 18. The hydrostatic transmission is in driving engagement with the pair of spaced wheels 22 for propelling the machine.

The spreader means 18 includes a first scraper means 60 and a second scraper means 62. The spreader means 18 also includes a rotatable spreader 64 comprising a plurality of elongated flexible rubber-like members of the type well known for use with this type of machine.

The tank 16 has an opening in the top which may be closed by the cover 66 which is hinged at 68 to the top of the tank. A bracket 70 is attached to the tank and limits opening movement of the cover 66 as illustrated in phantom in FIG. 1. Also disposed within the tank 16 is a rotary agitator means 72 for mixing the fluid disposed within the tank 16.

A conduit shown in phantom at 74 in FIG. 1 extends from the bottom of the tank 16 to a valve 76 disposed above the first scraper 60. A control lever 78 is pivotally supported on the tank 16 and is connected to the valve 76 by the linkage means including the links 80, 82, 84 and 86. Movement of the control lever along the side of the tank 16 opens and closes the valve 76 to selectively dispense fluid from the tank 16 to the first scraper 60.

As illustrated in FIG. 3, motion transmitting means comprising sprockets 88, 89, 90, 91, 92 and 93 and the chains 94 and 96 operatively interconnect the hydrostatic transmission of the drive means 58 and the agitator means 72 and the rotatable spreader 64 for rotating the same.

There is also included a power control means including the handle 98 which is operatively supported by the tank 16 adjacent the dirigible wheel assembly 26 and the links 99, 100 and 101 which operatively connect the handle 98 to the hydrostatic transmission for controlling the direction and speed of movement of the machine.

The container 102 serves as a reservoir for supplying fluid to the hydrostatic transmission.

The operation of the machine is apparent from the above description but will be briefly reviewed. When the machine is not being used to apply a coating, it is stored and driven in the position illustrated in FIGS. 1 and 3. In this position, the lever 30 is in the extreme forward position or in the extreme raised position. The valve 76 is closed and the spreader means 18 is raised from and spaced from the surface 20 supporting the machine. When the machine is in the position illustrated in FIGS. 1 and 3, it may travel in either direction and if traveling to the right as viewed in FIG. 1, dirigible wheel 50 will be in the position shown in FIG. 1. However, if the machine is traveling to the left as viewed in FIG. 1, the dirigible wheel 50 will be reversed and will be in the position illustrated in FIG. 2.

When it is desired to apply a coating to a surface, the tank 16 is filled with fluid and the lever 30 is moved to the position illustrated in FIG. 2 which is the extreme lowered position where the spreader means 18 engages the surface 20. The power control handle 98 is moved to the position where the machine moves to the left as viewed in FIG. 2 and at the same time the handle 78 is manipulated to allow a certain amount of fluid to be dispensed to the left of the first scraper 60 which extends across the machine and has engulfing sides as illustrated. Preferably, the first scraper 60 is of a configuration to form a rectangular elongated pocket into which the material is dispensed. As the machine moves over the surface, the rotating spreader 64 spreads the material over the surface followed by the material being engaged by the second scraper 62. As the machine is moving over a surface, it is steered by moving the handle 54.

The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation.

Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.

In 1981 Neal meet this challenge with its introduction of the industries first 550 gallon tow behind spray applicator. The Neal 550’s spray system was driven by a Bowie rubber gear pump with in-tank agitation to suspend aggregate for the duration of the job. For the first time contractors were given the ability to spray sealer that met or exceeded industry standards for proper mix design with sand. Because of its high capacity and tow behind capability, the Neal 550 was also the first machine to provide professional contractors an efficient solution to sealing large commercial parking lots.

It is no exaggeration to say the Neal 550 revolutionized the sealcoating industry. Because of the power of this one machine, sealcoating became a highly profitable field, with an entire new world of possibilities. Due of the overwhelming response to the 550, Neal began to search for other new ways to increase the profitability and efficiency of its sealcoating equipment. It was this quest that led to the introduction of the Neal ESP Piston Pump in 1984. Dissatisfied with the longevity of the rubber gear pump, piston pumping eliminated the wear of the rubber gears caused by aggregate, and satisfied a growing need for increased durability in the pumping system. With the ESP pump Neal introduced the industries first pumping system designed specifically for sealcoating equipment. High powered, with virtually no maintenance (just like it is today!), the ESP could pump an unprecedented 50 gallons of material per minute for material transfers and provide a continuous even pressured supply of material to the spray wand and spray bar without interruption. This second revolutionary idea gave birth to the new and improved Neal ESP 550.

In 1985 Neal introduced the industries first (yes, another one) ride-on spray machine. Taking the classic 210 squeegee model, Neal integrated its ESP pump system giving the system unheard of capabilities. It was this model that established a new standard for applying sealer to the asphalt surface. With the ability to squeegee material down into the pores (low points) of the surface on the first coat, and spray on the second (hitting the peaks of the surface), a higher standard of quality could now be offered to the customer.  This new level of quality offered the sealcoating contractor a better, longer lasting, product for customers when sealing high traffic areas.

In 1986, and with more than 70% market share of the industries sealcoating equipment, Neal raised the bar once again. With the introduction of the ESSP 100 gallon per minute pumping system, Neal gave the contractor more efficient methods of applying sealer to the asphalt surface. With this new, higher pumping capability, Neal introduced the material spray bar. The spray bar attached to the back of any Neal unit, and provided high speed, high powered application of sealer to the surface. Additionally, and because of the increased psi provided with the ESSP Pump, contractors could now for the first time, spray with a distributor bar applying up to 15 foot widths with sand loads, without loss of pressure.

In 1986 and 1987 successively, Neal introduced the SM and DA 350, the industries first 350 gallon self propelled applicator. Now with increased capacity and the new ESSP piston pump, a new level of efficiency was born. Capable of squeegee application, distributor bar application and spraying with two hand wands, the DA-350 quickly became the new “King” of sealcoating machines.

Through the innovations and creativity of Harold Neal and Neal Manufacturing Company, the face of sealcoating had been changed forever. For the first time, affordable, high powered solutions for applying sealer to asphalt gave the sealcoating industry new possibilities and standards. What began as a marginally profitable career path, through the efforts and imagination of one company, became a highly profitable career for thousands of contractors around the nation.

Due in part to the imagination of contractors all over, Neal has produced sealcoating equipment in all shapes and sizes. Many standard models we now produce were born from the ideas and creativity of our customers. The Neal Fabricated Truck System, Skid models - and even some models that weren’t all that successful - have all added to a 30 year tradition of providing customers with high quality sealcoating equipment.

Over 20 models of sealcoating equipment and 30 years later, Neal still manufactures the most durable and efficient sealcoating machines. It only takes a quick browse of current equipment standards to realize the incredible influence Neal has had on this great industry.

The same tradition of high standards and creativity that drove Neal in those early years are the same that drive us today. Call us today to discuss how Neal can help you to become more efficient and more profitable. Let us be your partner in sealcoating.

Summary: Blacktop and asphalt sealing is incredibly important for maintaining a good driving surface. With three basic types of sealers to choose from, which should you use? Follow these tips for an excellent sealing job.

Different Sealers

There are three basic types of blacktop or asphalt sealers: simple emulsified asphalt; refined coal tar sealers; and 100 percent man-made acrylic polymer sealers.

The simple asphalt emulsion sealers offer the lowest levels of protection. In essence, they simply contain the same asphalt that was used to bind the sand and gravel together in the first place. This asphalt coating will oxidize and get brittle just like the asphalt you are trying to protect!

The next best sealer to use is manufactured using refined coal tar. Refined coal tar offers two distinct advantages: it is not dissolved easily by gasoline; and oil and UV rays do not readily make it brittle.

Asphalt is easily dissolved by gasoline and oil drippings from your car. Because of this, you should consider using refined coal tar products.

There is a wide variety of refined coal tar products. Some of them have additional additives such as rubber and rubber-like polymers which make them more elastic. These sealers often contain fine sand and clays. The sand makes the sealers more durable. The clays make the sealers easier to apply.

The best and most expensive sealers you can buy are those that contain almost 100 percent man-made ingredients. These are the acrylic sealers. If you have ever played tennis on a blacktop court that has the distinctive green and red sealers, you have walked on these acrylic sealers.

Asphalt Pothole Repair Repair options:

The three main types of repair products are cold asphalt, hot asphalt, and polyurethane.

Longer-lasting than cold asphalt, hot asphalt is mixed around 350 F. The repair and compaction must be done while the asphalt is still hot.  Cold asphalt is mixed and used at lower temperature than hot asphalt. Cold asphalt is easy to work, compact and repair potholes with, but does not last as long as other repairs.  Polyurethane repairs are done in any season provided the pothole can be dried. Although they tend to be more costly, polyurethane repairs last longer.
