IN VEN TOR. MARVIN L. CHRISTENSEN ATTORNEYS United States Patent 3,173,166 ASPHALT SHINGLE TABBER Marvin L. Christensen, 3545 Meadowbrook Drive,

Murray, Utah Filed Apr. 15, 1%3, Ser. No. 273,106 8 Claims. (Cl. 545) This invention is concerned with roof shingling, and more particularly with a machine for rapidly tabbing asphalt shingles in place on a roof.

It has long been common in tabbiug roof shingles to manually raise the overlapping portion of each individual shingle of a row of shingles, apply an adhesive material therebelow, and return such raised overlapping portion to its normal position. This has been a tedious and time consuming process.

It is a primary object of this invention to provide a machine that will progressively raise the overlapping portions of successive asphalt shingles of a row of same, apply a substantially uniform line of an adhesive material, such as tar, beneath their forward edge margins, and guide them back -to their normal positions, whereby a neat and long lasting roof cover is formed.

A principal feature of the invention is an applicator foot that will raise each successive shingle as it is moved along a row of shingles, and through which adhesive can be uniformly supplied beneath the raised shingles. The foot preferably comprises a surface engagement means, a shingle supporting surface, a guide wall, and an adhesive applicator port. The shingle supporting surface is preferably formed in three sections and includes an arcuate center section and blade-type extensions pivotally connected at each end of the arcuate center section.

Other features of the invention greatly facilitating the tabbing of shingles are an extension handle fixed to the applicator foot; a spring biased, normally closed, control valve, positioned in a conduit for supplying adhesive to the adhesive applicator port; and remote control means -for the valve, operated from the end of the handle opposite the applicator foot.

There is shown in the accompanying drawing a specific embodiment of the invention representing what is presently regarded as the best mode of carrying out the generic concepts in actual practice. From the detailed description of thispresently preferred form of the invention, other more specific objects and features will become apparent.

In the drawing:

FIG. 1 is a fragmentary perspective view of the adhesive applicator as used in roofing operations;

FIG. 2, an end elevation of the adhesive applicator;

FIG. 3, a side elevation of the applicator foot; and

FIG. 4, a bottom plan view of the applicator foot.

Referring to the drawing:

In the illustrated preferred embodiment, the adhesive applicator shown generally at 10 includes a handle 11, a foot 12, a supply conduit 13, and a control valve 14 positioned in the conduit and fixed to handle 11.

A control lever 15 is pivotally mounted adjacent one of the grips 16 of the handle, and is connected by wire cable 17 to the free end of actuating arm 18 of valve 14. Valve 14 may be of any conventional type, but preferably is either a conventional rotary or butterfly valve, with a stem 19 connected to the valve head and extending through the valve housing. Actuating arm 18 is fixed normal to stem 19, and a coil spring 20, having one free end anchored to arm 18, as at 21, and its other free end anchored, as at 22, to an extension 23 of the valve housing, surrounds the stem and normally biases the valve to closed position.

The wire cable 17 interconnecting the control lever 15 and the actuating arm 13 passes through one or more 3,173,166 Patented Mar. 16, 1965 guides 24, such that when control lever 15 is pivoted toward grip 16, the motion is transmitted through the cable to actuating arm 18, which is similarly rotated to open valve 14. Spring 20 will rotate the actuating arm back to the valve closed position when the control lever is released.

Supply conduit 13 is connected at one end to a source of adhesive not shown, and adhesive is supplied to the conduit underpressure. The other end of conduit 13 is connected, as shown, to port 25 of foot 12.

The source of adhesive and pressurizing means, not shown, may for example, comprise a reservoir and pump unit in conduit 13, or a pressurized adhesive container that is either portable or stationary, as desired.

As best seen in FIGS. 3 and 4, foot 12 has a surface engagement means in the form of a narrow bottom runner 26, and an arcuately shaped shingle supporting surface formed in three sections, 27, 28, and 29. The runner and the center section 28 of the shingle supporting surface are rigidly interconnected by a guide wall 30!, which extends upwardly from the runner and protrudes beyond the top of the center section 28 of the shingle supporting surface.

v Port 25 extends through guide wall 30 between the runner and the shingle supporting surface, and terminates at the edge of the runner, as shown in FIG. 4.

Pivot pins 31 are fixed to guide wall 30 at each end of the center section 28 and end sections 27 and 2? are pivotally mounted thereon. As shown, each of the end sections is of blade-like configuration with a guide ear 32 spaced slightly from, but cooperating with, guide wall 30. The plane of each of these cars forms aslight angle with respect to the plane of the guide wall and extends from the end of the guide wall outwardly and away from the free edge 33 of the shingle supporting surface to avoid damaging the shingles. With this arrangement, as the foot is moved along a line of shingles on a roof, the overlapping sections of the shingles 34 (FIG. 1) are raised onto the supporting surface, as will be further explained. The raised edge 34a of each shingle contacted by guide ears 32 and guide wall 30 will serve as a ruling guide to insure a substantially straight line of adhesive being applied beneath the shingle.

The end sections extend beyond runner 26 and are biased by coil springs 35 into contact with the ends of the runner. In this biased position, the free ends of the blade-like end sections will extend downwardly to a point below the plane of the runner. Because they are pivotally connected at 31, however, the end sections can be pivoted upwardly so that their undersides 27a and 29a will be at least even with the underside of runner 26. As thus constructed, when the foot is moved along a line of shingles, the leading end section will closely follow the roof surface and will drop sufticiently to pass under even lower than usual shingles, thereby guiding them onto the shingle supporting surface.

One end of each of the coil springs 35 is anchored to the center section 28, as at 36, and the other end is anchored to a end section at 37.

As the foot is pushed along on runner 26 by an operator grasping grips 16 of handle 11, the shingles are successively raised, and held raised, as the shingle sup porting surface of the shoe passes thereunder. Simultaneously with movement of part 25 past each shingle, the control lever 15 is operated to open valve 14 and release a continuous, uniform line of adhesive through conduit 13 and the port. The volume of adhesive applied beneath the shingles is controlled by the pressure applied to the control lever and the resultant degree of opening of valve 14.

After the shingle supporting surface passes from un- 3 der each shingle, it will fall back to the roof and be stuck or tabbed in place.

Because of the similar construction of the pivotally mounted

end sections

27 and 29, of the shingle supporting surface, either of them can be utilized as a leading end section during tabbing operations. Thus, after one leading edge has been used to raise one line of shingles for tabbing purposes the handlell can be pivoted with respect to foot 12 and. another line tabbed,but with the other end section now serving as the leading end section; and with the operator moving in the opposite direction across the roof.

Although the curved threepiece arcuate shingle supporting surface is most desirable inasmuch as it presents a smooth surface capable of easily lifting, sliding beneath, and lowering a shingle, other configurations utilizing, for

example, sloping surfaces with a'peak above port 2S could be used. Similarly, although the surface engagement means has been here illustrated and described as a runner 26, it is contemplated that for some uses Wheels or rollers may be found preferable, and it is further contemplated that other biasingmeans than the springs 35 may be used. For example, for many uses the weight of the extensions themselves may prove sufficient to maintain the end sections in engagement with the roof, irrespective of surface irregularities therein.

Whereas there is here illustrated and specifically described a certain preferred construction of apparatus which is presently regarded as the best mode of carrying out the invention, it should be understood that various changes may be made and other constructions adopted without departing from the inventive subject matter particularly pointed out and claimed herebelow.
