United States Patent() 3,146,485 MASTIC APPLICATOR Ruhe P. Evans, P.0. Box 42, Thornton, Calif., and

Donald R. Reid, 6821 Chevy Chase Way, Sacramento, Calif.

Filed June 4, 1962, Ser. No. 199,981 1 Claim. (Cl. 15--595) This invention relates to a mastic applicator, and has as its primary object the provision of a device which will lift the tabs of composition shingles, and simultaneously apply mastic thereunder for securing the shingles in position.

A further object of the invention is the provision of a device which may be run transversely along the edges of a roll of shingles, and apply a requisite amount of mastic under each shingle with a minimum of time, effort, and diiculty.

A further object of the invention is the provision of a device of this character which is provided with a lifting mechanism whereby the tab of the next adjacent shingle may be lifted simultaneously with the application of mastic under the preceding shingle, whereby the application of mastic to a composition shingle roof or other structure may be materially expedited.

A further object of the invention is the provision of a device of this character wherein the mastic is applied in desired amounts by a pressure pump or analogous device.

Still another object of the invention is the provision of a device of this character which is provided with a reversible handle, so that the device may be run in either direction, or alternatively, shifted in its direction of movement at the end of the path of travel thereof.

A still further object of the invention is the provision of a device of this character which is sturdy and durable in construction, reliable and efficient in operation, and relatively simple and inexpensive to manufacture and utilize, and which may be expeditiously and easily operated by a single operator, thus resulting in a material saving in time and cost.

Still other objects will in part be obvious and in part be pointed out as the description of the invention proceeds and shown in the accompanying drawing wherein there is disclosed a preferred embodiment of this inventive concept.

In the drawing:

FIGURE l is a side elevational view of one form of device embodying the instant invention shown in association with a roof formed of composition shingles, the latter being partially sectioned.

FIGURE 2 is a top plan view of the structure of FIG- URE l, showing the same in use along a roof.

FIGURE 3 is an enlarged sectional view taken substantially along the line 3 3 of FIGURE 2 as viewed in the direction indicated by the arrows.

FIGURE 4 is a reduced sectional view taken substantially along the line 4-4 of FIGURE 3 as viewed in the direction indicated by the arrows; and

FIGURE 5 is an enlarged sectional view taken substantially along the line 5-5 of FIGURE 4 as viewed in the direction indicated by the arrows.

Similar reference characters refer to similar parts throughout the several views of the drawing.

Having reference now to the drawings in detail, one form of apparatus embodying the instant inventive concept is generally indicated at 10. The apparatus of the instant invention comprises a base 11, to the upper side of which are secured a pair of bearing brackets or blocks 12, the securing means taking the form of bolts 13, which extend through aligned apertures in lugs 14 carried by the bearing brackets 12 and plate 11. Bearing brackets 12 have suitably secured for rotation therein an axle or ICC pivot 15, which is provided with a central T-shaped member 15a having a stem 16 which may be provided with an internally threaded bushing (not shown) to which is secured the threaded lower end 17 of a handle member generally indicated at 18. The handle has a downwardly deviating distal end. Handle member 17 includes a T- tting 19 into one end of a cross piece of which fits the threaded end of portion 17, it being noted that portion 17 is solid. The other end of the cross arm is connected to a hollow pipe 20, which is provided adjacent the T-iitting 19 with a manually controlled mastic regulating valve 21. Valve 21 is controlled by a manual operating handle 22.

The other end of pipe 20 is connected by a suitable iitting 23 to a iexible hose 24 which extends to a source of mastic, and a pressure pump, for feeding mastic into the interior of pipe 2l).

The stem of T-iitting 19 has threadedly secured therein a suitable coupling 25 which is connected to a liexible hose or tube 26, which extends in turn to a fitting 27 which is threadedly secured as at 2S to the interior of a nonrotating hollow axle 29. Axle 29 is secured to the underside of plate 11 by means of circular ttings 3A0, which include stems 31 extending upwardly therefrom, and cross pieces 32. The cross pieces 32 are also apertured in alignment with the apertures in plate 11 to receive the bolts 13, the several parts being secured in related assembly by means of nuts 33. The other end of hollow axle 29 carries an elbow 34 from which extends a mastic applying nozzle 35.

Suitable identical wheels 36 are carried on each end of axle 29 exteriorly of the fittings 30 and spaced therefrom by means of spacers 37. Nuts 38 threaded on each end of the axle 29 serve to hold the wheels in position thereon.

The end of plate 11 adjacent nozzle 35 extends outwardly over its associated wheel as indicated at 39, and has secured thereto by means of bolts or rivets 40 an arcuate tab lifter 41. As best shown in FIGURE l, the tab lifter extends in a double arc or sinusoidal curve to a point 42 at each end thereof and then includes a reverted upturned portion 43, so that the same may be extended under the tab T of an associated composition shingle S in either direction of travel.

From the foregoing the use and operation of the device should now be readily understandable. The device is started at one end of a roof R, which is supported by rafters R', as shown in FIGURE l, beneath the tabs of the roll of shingles, with the pointed end 42 of tab lifter 43 being inserted thereunder. Mastic is then supplied through the pipe 20, and controlled by valve operating handle 22. As the device rolls along the tabs T of each shingle are lifted, and mastic M (see FIGURE 1) is applied thereto through nozzle 35. As the device is progressively rolled along a roll of shingles the tab of the next shingle is lifted as indicated at T in FIGURE 2, while mastic is being applied under the tab of the preceding shingle. By virtue of this arrangement the tabs of a large number of shingles may have mastic applied to the undersides thereof with a minimum of effort and difficulty, and, by virtue of the arrangement of pivot 15, when one end of the roof has been reached, the handle may be rotated about pivot 15 to extend in the opposite direction, in the direction of travel and the device may be reversed for applying mastic to the next row of shingles.

From the foregoing it will now be seen that there is herein provided an improved mastic applicator for composition shingles which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be 3 understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.

We claim:

A mobile apparatus for the continuous application of mastic to the underside of composition shingle tabs comprising in combination,

a base plate arcuately downwardly concave in crosssection on a vertical plane parallel to the direction of movement of the apparatus,

a hollow non-rotating axle transverse to the direction of movement of the apparatus dependently carried from said plate and held against sidewise movement with respect to said base,

the axis of said axle defining the approximate center of curvature of said base plate,

a pair of identical wheels trunnioned one each on an end of said axle and held against longitudinal movement with respect to said axle,

the radii of each Wheel being somewhat less than the radius of curvature of said base plate,

a handle mounted upon the top of said base plate and pivoted thereon so that it may pivot in a vertical plane perpendicular to said axle,

the handle being straight for a major portion of its length and possessing a downwardly deviating distal end,

the handle also being hollow from its distal end to a point spaced from its lower end from which point downward it is solid,

a transversely extending shingle tab lifting plate of generally sinusoidal vertical section carried at its maximum height portion by said plate and extending transversely over and beyond one of said Wheels,

the lowest end portions of said lifting plate being substantially horizontal and including reverted upturned portions,

means at the distal end of the handle which are adapted to connect the handle with a source of mastic under pressure,

a control valve in the hollow portion of the handle to control the mastic flow therethrough,

a T coupling between said hollow and solid portions of said handle with an outwardly directed stem,

a flexible tube connecting the stem with one end of said hollow axle,

and the other end of the hollow axle, namely, the end which is below said shingle lifting plate, possessing a downturned elbow, carrying a mastic applying nozzle.
