UNITED STATES PATENT QFFICE.

ALONZO MCMANUS, OF NEW BRITAIN, CONNECTICUT.

SPUR.

SPECIFICATION forming part of Letters Patent No. 255,879, dated. April 4, 1882.

Application filed July 18, 1881. (No model.)

To all whom itmay concern:

sition for the reception of the rowel, said rim and arms consisting of only one and the same piece of metal; and the objects of my invention are to save labor and to produce a light, neat, and substantial article at a moderate cost. I attain these objects bythe simple constructionillustrated in theacconipanying drawings, in which- I Figure 1 is a plan view; Fig. 2, a side elevation; Fig. 3, a rear elevation, and Fig. 4 a rear elevation showing a different form of spur which embodics the generic features of my invention.

A designates the rim, a a the arms which form the neck, and B the rowel, all of which, exceptin the particulars hereinafter specified, may be in any desired form, and are substantially the same as those in common use.

I prefer to form the rim or heel-baud clasp A of sheet metal and to cut the lugs which form the rowelarms a a out from the body of the rim A uponboth sides, and when so cut to bend them toward each other to form the neck in which to pivot the rowel B, as shown in Figs. 1, 2, and 3. In this case the arms are cut by dies and punches, which leave the stock uncut upon those ends or sides of the dies which confront the neck, so that said arms may be bent toward each other and have a solid and uncutportion of the rim between them. The metal is simply slit to form the ears without removing any substantial portion; or, in other words, the arms consist of the stock which is removed from the body of the rim at the punched or perforated portions. This construction is very simple and inexpensive, and the rim and arms are formed complete from only one piece of metal, thereby avoiding all necessity for rivets or other fastening device. In the form shown in Figs. 1, 2, and 3 the edge of the rim is of the ordinary form and of full width. Other forms of blanks may be employed to produce my spur, one of which dift'erentforms is hereinafter described. The shape of the arms is immaterial.

In the foregoing construction, and also in that hereinafter described, the rim or heelband clasp A is of'a single thickness only at the back part and without any rivet or rivets passing thorugh it at said part, whereby it is not only light, neat, and substantial, but is quite springy, and has no objectionable seam orjoint at that point.

In Fig. 4 I have shown another form for making the rim and arms of one piece, and with the arms bent toward each other, sub stantially as before described, but in a less desirable manner, because the rim A/"is narrowed by removing the arms a a. from one edge of the rim. The broken lines indicate the outside edge ofthe arms a a before being bent from the rim, and also that halt of said arms that have surplus metal trimmed off from them. The remaining halfofthe edges ot'the arms a a are simply slit from the body of the rim without removing any stock.

I I am aware that aprior patent shows a spur in which the heel-band clasp is formed of two pieces riveted together, and with portions of their meeting ends turned up to form the roweLarms, and the same is hereby disclaimed.

I claim as my invention- 1. In a spur, the rim or heel-band clasp consisting of a single piece of metal, having the lugs which form the rowel-arms turned up therefrom and formed integral therewith, substantially as described, and for the purpose specified.

2. In a spur, the rim or heel-band clasp A, having the lugs which form the rowel-arms a cent out and turned back from the body of G. H. AVERY, A. W. STANLEY.
