SHINGLE REMOVER Filed Aug. 29, 1929 INVENTOR 10 BY [90 Zebmm j}? 5 J3 ATTOR/Y'EY Patented Jan. 12, 1932 PATENT OFFICE LEO LEHMAN, OF POMEROY, WASHINGTON SHINGLE REMOVED,

Application filed August 29, 1929. Serial No. 389,145

This invention relates to shingle removers 4' and has as one of its objects to provide a tool adapted to remove shingles in their logical .and in their reverse order in which they were laid.

Another object of the invention is to provide a shingle remover that by removing the upper course first will deposit all dirt and removed shingles to the ground over the unremoved shingles.

A further object of the invention is to provide a shingle remover .that will operate between the sheathing boards and without interference from the rafters thereby providing for greater rapidity inthe work, the work being thus unobstructed by the remaining standing shingle nails.

' A further object of the invention is to provide a shingle remover that is relatively light in weight and that is provided with adetachable handle for convenience in storage 1 and shipping.

A further obj ect of the invention is to prob vide a shingle remover that by its design is especially adapted to start the work with the greatest ease and rapidity.

A further object of the invention is to pro- I vide a shingle remover that by operating between the sheathingboards will act as a safeerence is now had to the accompanying drawingsin which Fig. 1 is a side elevation of a fragment of a roof;

Fig. 2 is an end elevation thereof showing the position of the device with respect to the roof- Fig. 8 is an enlarged side elevation of the shingle remover showing one position of the device during operation;

Fig. 4: isa plan view of the device showing its relative size with respect to the space between the sheathing boards and the rafter and Fig. 5 is a similar view to that of Fig. 3 showing another postion of the device durin operation.

illaving reference to the drawings like numerals refer to like parts throughout the several views and the numeral 1 refers to a shingled roof composed of shingles 2, laid in the usual manner on sheathing boards 3, which sheathing boards are in turn supported by rafters 4, the different components being assembled in the usual manner of such construction, with th eaves 5 of the roof repre senting the lowermost part of the roof, and the comb 6 representing the uppermost part 7 thereof.

It is the general practice in such roof construction to save lumber by laying the sheathing boards 3 about 2 inches apart, and as the lumber is 1 inch stock (nominal dimension) there remains a space approximately 1 inch between the rafters 4 and the underside of the shingles 2 by 2 inches between the sheathing boards, and this space is taken advantage of as will be noted as the specification proceeds.

The shingle remover 7 forming the subject matter of this invention consists generally of a bayonet shaped tool 8 having a handle 9, elongated as shown for two hand operation, which is detachably attached thereto for the purpose of removal for convenient storage or shipping, and specifically the tool consists of an elongated blade 10 sharpened preferably to and terminating in a point 13, the sharpened point being shaped to force an entrance under the shingles under all conditions that may be encountered, more particularly when starting the work, and the point is further preferably tapered from both edges of the blade, as shown in Fig. 4, whereby to glance away from the nails that hold the shingles when it is necessary to pass the blade between the sheathing board and the shingles, by which taper no appreciable interference will be encountered which would be the case were a blunt or broad tool used.

Formed integral with the blade 10, and extended at approximately right angles thereto, is the riser 14 which meets the blade with a curve 15, the curved portion being formed in the riser with the blade forming a tangent thereto. the curve shown in Figs. 3 and 5 is relatively large it is thus shown to illustrate the action of the tool, since in practice the curve will be smaller whereby with the power applied to force the blade under the shingles the smaller curve will tend to break the shingles quicker (rather than bending them as shown) resulting in expediting the work.

The tool 8 is completed with a shank 16 which is also preferably an integral part of the tool, and the shank normally extends in a line paralleling the line of the blade, and is disposed to receive the handle which is secured thereto'preferably by means of U bolts 17, or other simple means which willpermit of its ready removal, which handle is intended for convenient and proper manipulation of the tool.

The tool is constructed of a comparatively narrow thin, flat strip,0f yielding or resilient material, preferably of uniform cross i the tool is determined by the nature of'the material used, and is such aspto provide the necessary resiliency, i. e. to yield under heavsection throughout its length, and its blade dimensions are such as to permit its entrance in the space bounded by the shingles and rafters and the two adjacent sheathing boards of greater width than the thickness of the sheathing boards. 4

The thickness dimension of the material of ier work as where the shingles are exceptionally well secured, and to remainrigid under the lighter work. i

By its resiliency the tool under the heavier work will assume the position (exaggerated) shown in Fig. 5 when forced under the shingle preparatory to lifting them wherein it will be noted that the curvature 15 of the riser 14; is greater than shown in Fig. 3, (also exaggerated) and by thus increasing the curvature the wedge or lifting effect is greater, due to I the yielding qualities which permit the change and by means of the sharpenedpoint 13 of of curvature.

In use the work is started by providing a hole that will permit the entrance of the tool at the comb of the roof, or obviously the roof may bebroken into at a valley (not shown),

the blade.

The hole being started its size is increased until the blade may be operated with a swinging movementunder the shingles 2, passing over the rafter l whenthat member is in the vicinity of the actual operation, and the motion of swinging brings the curved portion 15 of the riser in contact simultaneously with the underside edge of the shingles.

This operation starts lifting the shingles as the blade proceeds along their underside, and simultaneously finishes raising the Let it here be understood that while" shingles, which are now loosened, by contact with the curved portion of the riser the resiliency of the tool preventing jar to the handle during the operation.

This last part of the operation (obviously in cooperation with the first part) provides a lifting effect which'bends the shingles upward 'totheir breaking point when the natural resiliency of the shingle, augmented by theresiliency of the tool, causes the shingle to break and fall over onto the unremoved shingles.

The sharpened point 13 permits driving the tool between the shingles and the sheathing without considering the location of nails, or whenever stubborn resistance is encountered. 7

Obviously there is no dirt between the sheathing boards, instead all dirt lays between the superimposed shingles; hence, operating from the comb of the roof down, the removed shingles will be thrown over onto the unremoved shingles, and will carry with them practically alldirt, with the result that the dirt and old shingles are prevented from falling into the building, and are swept or fall by gravity to the ground. This obviously 'diii'ers from the effect of-working from the eaves'upward as in this case all dirt and much of the shingles would eventually land in the interior-of the building.

Having thus described my invention, I claim:

1. A shingle remover consisting'of a re: silient tool formed bayonet shaped of a narrow thin flat strip, and provided with a bination of a resilient tool of uniform cross section throughout its length, and formed of a narrow thin flat strip of yielding material having a greater width than the thickness of the sheathing boards which carry the shingles, and having general dimensions adapted to permit its entrance between shingles, between the shingles and the supporting rafters, and between the edges of adjacent sheathing boards, and provided with a two hand handle detachably attached thereto, and comprising an elongated blade terminating in a sharpened point, ta-

pered from both edges of the blade, a riser formed integral with and leaving said blade with a curve, and a shank formed integral 3. A shingle remover consisting in com;

with said riser and normally extending in a. line paralleling the line of the blade, and adapted to receive said handle, said riser being disposed with respect to the blade and shank to cooperate with said members to yi'eldingly engage underside and the edge of said shingles simultaneously and without jar to the handle during operation.

In testimony whereof I afiix my signature.

LEO LEHMAN.
