BACK-BAND HOOK.

SPECIFICATION forming part of Letters Patent No. 337,215, dated March 2, 1886.

Application filed December 17, 1885. Serial No. 185,918. (No model.)

To aZZ whom, it may concern:

Be it known that I, SETH VVARD, a citizen of the United States, residing at Princeton, in the county of Gibson and State of Indiana, haveinvented certain new and useful Improvements in Back-Band Hooks, of which the following is a specification, reference being had therein to the accompanying drawings.

My improvement relates to back-band hooks for harness, and isintended as an improvement on Patent No. 62,513, dated February 26, 1867, and issued to me.

The improvement in this case relates more particularly to the shape and construction of the body of the hook and of the eyes formed therein, as will be hereinafter set forth.

In the accompanying drawings, making part of this specification, Figure 1 represents a perspective of the hook secured to a section of back-band. Fig. 2 is a plan View. Fig. 3 represents a longitudinal section of the hook and a portion of the band, and Fig. 4. represents a cross-section of the hook and section of the band.

In the figures, A represents the body of the hook. One of the peculiarities is the raised or ridge back D.

In the patent to which I have'referred, and upon which this is an improvement, the main portion of the body and that which came in contact with the leather of the band was fiat. The difficulty I found with this fiat body was thismoisture would collect beneath it, and remain and rot the leather. This I have obviated by the present construction. From :0 to m, it will be seen, that I leave in the body ofthe hook a narrow bearing-surface for the leather, which is punctured with holes for rivets to pass through. The body from this bearingsurface is made hollow on the inner or under side, and rises, forming a ridge, D, which allows the body to stand away from the leather, and thus prevent moisture from collecting. The narrow space which is left for allowing the hook to be confined to the leather allows moisture to escape, and thus prevents rot. This construction is productive of afurther advantage, which is clearly shown in Fig. 3. It allows the point 0 of the hook to be bent around and under the ridge in such manner that it will more securely hold the trace.

I have used a modification in which, instead of forming a ridge on the back, I out the metal away and form a skeleton bodyanirnportant feature in the construction of this hook, which, while it may appear trivial, is of greatimportance in the actual use of the invention. This feature is the shape of the countersinks a a a in the rim of the body, in which the rivet-heads press the leather when the parts are being secured together. This countersink is made wide and slightly hollowing, but without any abrupt or sharp edges to out the leather. The countersink is made shallow, so as to barely flush a fiat thin-headed rivet, F, which is slightly convex on its under side. The convexity of the rivet-head and the concavity of the countersinks conform to each other in shape, and the leather is never out or split in confining it' to the hook, all owing to this peculiar construction. The ridge upon the back of the hook serves'to give it strength without materially increasing its weight.

To compensate for the loss of metal by mak ing a wide countersink, I have a small boss thrown up on the opposite side, whichgives the hook all necessary strength.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

As an articleof manufacture, a hack-band hook constructed of metal with a ridged back,- a corresponding depression under said ridge, an upwardly and inwardly turned point, and

countersunk flanged rivet-holes, all substantially as specified.

In testimony whereof I aifix my signature in presence of two witnesses.

SETH WARD.
