Specification-of-Letters Patent.

Application filed'Nhvembr 7; 191's. SerialNb. teases.

To all whom, it may concern? Be it known that 1, WILLIAM L. WHITTIER,

a citizen of the United States, residing at? Beverly, 111 the county of Essex and" State of" Massachusetts, have invented new and useful Improvements in SlllIlglG-StllPPGIS, of which the following is a specification.

This invention relates to improvements in shingle strippers. More particularly the invention relates to tools for strippingthe' shingles from the roof ofa house or other" building. The details of the inventionare set forth in the appended claims, the intention being that the patent, as expressed in the claims, shall cover whatever features of novelty exist in the invention disclosed.

'In the accompanying drawings: Figure 1 is a sectional elevation of a detail embodying the invention; and

Fig. 2 is a plan of the same.

Referring to the drawings, it will be seen that the tool consists essentially of the blade and a handle consisting of a socket piece.

11 and a wooden staff 12. The blade consists of a plate, which may preferably be of sheet metal of proper hardness and stiffness having a wldth, as seen in Fig. 2, suflicient to operate upon two or more shmgles at once.

The tool represented in the drawing, having a width of about seven inches, and having a length of about eight inches is suitable for this and for the diverse leverage functions about to be described. The forward end of the blade is provided with teeth 13 and is turned upward at a small but distinct angle with respect to the rest of theblade, thus dividing the blade into two portions marked respectively a and b. The angle 16 between these two is, in the specimen which is portrayed, about two and one-half inches from the forward edge of the blade; and the part a turns up from the plane of the part b at such an angle-that the edge of the blade is about seven-eighths of an inch above that plane. The teeth 13 are so designed as to engage under heads of nails which may be holding the shingles in place in order to eX- tract such nails by lifting them out of the wood. The considerable extent of the blade, in width, enables a number of such nails to be engaged at once wherever they may happen to be located along the width of the blade. A similar row of serrations or teeth 1% is represented as being at the rear end of the blade. The handle is attached at about the middle of the Z) portion and runs up backward, at "a small. angle with the plane of the Z) portion, and maybe of suitable length so that the implement, being held.

witli both hands, is used with a forward swinging or thrusting movement" of the In the'd'rawings the angle workmansarms. I of the handle isabout 30, and thehandle is maintained at this tween the twoportions a and" b. Upon depressing the handle, with the toolin that position, thebottom corner'16 of'the tool constitutes a fulcrum, close to the edge, so

that a powerful lift ing effect is exercised. After the handle has been depressed far enough the leverage suddenly changes and the rear end 14 of the blade constitutes the fulcrum. The result of this is, that in first starting the shingle, which may involve the withdrawing of some nails which are holding it, there is a powerful leverage; but after these nails have been withdrawn a distance great enough to loosenthem, which involves a relatively considerable downward swing of the handle 12, the leverage instantly changes so that during the latter portion of the downward swing a lifting movement of the forward edge 13 takes place, which is very considerable in extent as compared with the corresponding handle movement,

' because the leverage has suddenly been reduced .to one-third or one-fourth of what it was.

The breadth of the blade results in the tools picking up all nails within a fairly wide path; and the tool findsthese automatically as it swings in the workmans arms, without his having to look for or even to see them; and the combination of leverages is such that he can proceed rapidly along, with his body in suitable poise, without having this poise destroyed either by the exertion of strength required to extract the nails or by the length of body movement involved in following the swing of the handle.

In the nature of the work to which this implement applies the workman has to drive the forward edge into the rather small crack under a shingle. The swinging, thrusting,

I I angle byits'fiat'tene'd'en'd portion 15 which is securely riveted upon'the The rear teeth 14 are turned upwardly slightly, as s'eenin' Fig. 11

' Patented Mat; 6,191

motion with which the described tool is handled, which is made possible by the described construction, enables the WOIkIIlELIl" 16; after which the whole shingle and nailsmay be thrown up, and the region under the entire width of the tool cleared by slight further depression of the handle.

I claim as my invention:

1. A stripping tool for shingles comprising the combination of a broad plate of sheet metal having a forward edge continuously adapted to engage nail heads, and a handle extending backward from the upper side of the plate far enough to make thetool as a whole suitable for swinging by both arms of the user, said handle extending at an acute angle with the plate; the under side of the plate having a forma- Gopies of this patent may be obtained. for five cents each, by addressing the tion adapted to serve as a fulcrum near said forward edge and another formation adapted to serve as a fulcrum relatively far from said forward edge; whereby the forward swing of the tool engages it under a plurality of shingles, and depression of the handle lifts the said forward edge With a preliminary powerful and a subsequent rapidly moving leverage.

2. A stripping tool for shingles comprising the combination of a relatively broad plate of sheet metal bent at an obtuse angle near its forward edge and relatively far from its rear edge, combined with a handle long enough to adapt the tool for swinging forward by both arms of the user, said handle extending backward from the top of the plate at a small angle with the plane of the rear portion thereof.

Signed by me at Beverly, Mass, this twenty-ninth day of October, 1913.
