Nov. 22, 1932. R. M. GUTHRIE NONSPREADING STAPLE Filed Jan. 15, 1932 Invenlor filer? M fa flltomey Patented Nov. 22, 1932 UNITED STATES PATENT OFFICE BGZBEBT H. GUTEBIE, OF CHICAGO, ILLINOIS HONBPBEADING STAPLE Application filed January 15, 1932. Serial No. 586,577.
recess at one side thereof for receiving a Wire,
thus eliminating the two anchor prongs of the ordinary staple, with its liability of spreadmg.
Another object of the invention is to make the top part of the device adjacent the recess of hook shape, the parts so arranged that the portions under the recess will form a groove in the member through which the device is being driven, and in which the hook-shaped part enters so that there is no strain on the hook-shaped part which might be liable to bend the staple at a point where the head part joins the shank part of the recess.
A still further object of the invention 1s to so form the head that the blows thereon will comedirectly over that partof the shank between the recess and the opposite edge of the shank so that no strain will come on that part above the recess, thus reducing the chance of bending the sta le when the same is beingdriven into a mem r.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawin and I specifically pointed out in the .appen ed claims.
In describing the invention in detail, reference will be had to the accompanying draw ing wherein like characters denote'like or corresponding parts throughout the several views, and in which Figure 1 is a view partly in section show- 0 ing how the improved staple holds a wire to a post or other member.
Fig. 2 is a front view of Fig. 1. Fig. 3 is a view of the improved staple. Fig. 4 is an edge view thereof with parts in section.
and with the sides of the staple converging to a point at the lower and smaller end of the same as shown at 2.
A substantially arcuate-shaped recess is formed in the shank adjacent the uppe end thereof and opens out through sides and that edge which has the greatest inclination, but
this edge from the top wall of the recess to the head 4 is perpendicular to the head and the point where the greater inclination joins the lower wall of the recess is in the same plane as this perpendicular edge as shown at 5, so that when the device is driven into a post or the like, the major portion of the shank will form a channel which is entered by the hook part 6 so that this hook part does not have to force an entrance into the wood and thus no strain comes against this part 6 as it would if the said part 6 had to force its way into the wood. This prevents any danger of the upper part of the shank bending, while the staple is beingdriven into the wood.
The head-4 is formed with a beveled end 7, above the recess and the line a-a drawn from the point of the staple through the central part of that portion of the shank between the recess and the opposite edge passes through the exact center of that portion of the head which comes into contact with the driving implement so that blows struck the head b a hammer or the like will be directly over t is point and the strain will be taken by that part of the shank which is between the recess and the opposite edge and not by the part above the recess so that the chances of the shank bending when driven into a member are practically eliminated.-
The side faces of the staple may be rough and provided with the teeth 8 to make it more difiicult for the staple to be pulled from the member into which it is driven, though the head 4 facilitates the extracting of the staple by a suitable tool. This head also strengthens the hook part 6.
When building barbed wire fences it is sim ly necessary to drive the staple in about hal way and then the wire is placed over the hook after which the staple is driven home as shown in Fig. 1, sothat the wire is held in the recess as shown in Figs. 1 and 2. When building'a woven wire fence, the point of the staple is placed under the particular edge from the head to the bottom wall of the wire which it is desirable to fasten to the recess being perpendicular to the head and post and then the staple is driven into the the head having a beveled end located above post and during this operation, the edge of the recess, and the central part of that porthe staple moves the wire slightly until it tion of the shank between the recess and the 70 passes the point 5 and then it will spring opposite wall thereof being in vertical alinehack into the recess. When fastening the ment with the point. bottom wires of a fence, the staples should In testimony whereof I aflix my si nature. be driven with the hooks down. ROBERT M. GUT RIE.
From the foregoing, it will be seen that I have provided a sturd and non-spreading staple which will enab e one to easily and quickly attach fence wires to posts and the like.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the sco e of the appended claims.
aving thus described my invention, what I claim as new is I 36 1. A device of the class described compris- '90 ing a shank of wedge shape, a head connected to the shank and an upwardly curved recess in the upper part of the shank passing through both sides and one wedge of the shank, said edge from the head to the lower 95 wall of the recess being perpendicular to the head.
2. A device of the class described comprising a shank, of wedge shape, a head connected to the shank and an upwardly curved re- 100 cess in the upper part of the shank passing through both sides and one edge of the shank, said edge from the head to the lower wall of the recess being perpendicular to the head, 40 one end of the head being beveled and said 105 beveled part being located on the recess side of the shank.
3. A staple of the class described comprising a shank and a head on the shank said shank having flat sides with their extremi- 110 ties merging to form a point and the edges of the shank converging to the point with one edge being of a greater inclination than the other, and said shank having an upwardly curved recess therein adjacent the head pass- 115 ing through both sides and the said edge of the shank, the part of the said edge from the head to the bottom wall of the recess being perpendicular to the head and the head havin a beveled end located above the recess. me
