WHlFFLETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. 397,112, dated February 5, 1889.

Application filed May 24, 1888. Serial No. 274,936. (No model.)

To aZZ whom it may concern.-

Be it known that I, J OHN R. DAVIS, of Racine, in the count-y of Racine, and in the State of \Visconsin, have invented certain new and useful Improvements in 'hit'iletree-Hooks; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to whiffletree-hooks; and it consists in certain peculiarities of construction, as will be fully set forth hereinafter, and pointed out in the claims.

In the drawings, Figure 1 is a plan view of my improved device, partly broken away, showing the parts in an open position for the reception of the cockeye of a trace. Fig. 2 is a similar view, partly in section, on the line 2 2 of Fig. 3, but showing the cockeye in place and the parts closed. Fig.- 3 is an end view, and Fig. is a section on the lines 4 of Fig. 1.

My present device is an improvement on that patented by me on August 31, 1886, No. 348,191, and like that device consists of a ferrule and ring, to be applied to the end of a whiffletree.

A represents said whilfle'tree, having, preferably, a reduced end, 0,011 which the ferrule B is fitted. This ferrule '13 is cut out at its outer end from about on e-third to one-half of its circumference, as shown at l), and the remainder of said circumference is formed into a beveled flange, c, which projects beyond the periphery of the ferrule, being continued along each side of the cut-away portion, as shown at c, and terminating about in a line with the bottom of the notch 12, so as to form on each side of said notch-bottom the lugs or stops (1. There are two other lugs or stops, 6, extending back from the flange c to the same distance as the lugs d, the four lugs (1 cl e e forming, practically, the four corners of an imaginary square. In addition, at the inner end of the ferrule there is another lug, f, locatedabout midway between the described lugs or flange ends d d.

C is the hook, formed in one piece with its ring g, encircling the ferrule, and having its extreme end h bent at an aln-upt angle to the adjacent part of said hook, so as to exactly conform to the bevel of the inner face of the described flange c on the ferrule, as best shown in Fig. 2. The ferrule is formed with two holes, opposite each other, one between the lugs (Z and c on each side, and when the hook-ring is in place on the ferrule and thelatter fitted to the end of the whiffletree, a pin, D, is driven through each of said holes in the ferrule into the wood of the end a of the whiftletree. These pins are made of inalleable ll'ul'l, tapered as shown, so as to readily penetrate the wood, and notched out on oppoposite sides, as shown at 1 2", (the notch or groove being deepest and widest at its center and narrower and shallower at each end,-) so that when once embedded in the wood it cannot readily be withdrawn therefrom, as the fact of driving will tend to unite the wood and pins closely together, and the natural elasticity of the former will serve to crowd its fibers into the described notches, besides which the malleable metal will spread somewhat while beii'lgdriven and add to the firmness of its hold thereby.

E is the cockeye, and j the trace end, to which it is secured.

In my previous patent on which this is designed as an improvement I found that sometimes the ring of the hook, when the parts were in the positions shown in Fig. 1, had a tendency to slip back on the whiffletree beyond the ferrule, causing the parts to bind, which is entirely obviated by my present construction; and, further, I found that sometimes the point of my hook would slip off from the flange under great strain, and this I have remedied also, the angle of the point It and the inner surface of the beveled flange 0 now corresponding, as shown, which gives the said point a hold on the flange like a finger and entirely prevents it from slipping off, besides distributing the strain between the hook and ferrule, instead of causing it to be entirely borne by the former, as heretofore. Again, as the point h is now within the outer end of the flange c, it is effectually guarded from accidental contact with various objects, which might otherwise tend to interfere with its free action.

The operation and adjustment of my present device are practically the same as in my said prior patent and too obvious to require extended description, the wide recess b afiording an opportunity for the insertion of the coekeye flatly without twisting the latter to 5 one side-or inserting it from its edge, which is often inconvenient when attaehw'l to still? 1eather traces.

Having thus fully described my invention,

a 'l'errule titted thereto and secured by inalleable-iron pins d riven through holes in said :l'errule into the wood of the wliittletree end, said ferrule being notched or recessed at its periphery l'or 'l'roin about (me-third to about one-halt of its OiP011111fUl'(fll((, tlJQVOlCtl flange extending around the said pm'iphery and down alongside the edge ot' the reeess, terminating in lugs on each side therein, other lugs extendinglmek from said [tango and forming the corners of a square with the just-named lugs, a hook-ring surroulnling said ferrule ring surrounding said ferrule and malleable iron pins adapt-ed to be driven through said holes into the wood of the whilfletrce end, and to limit the play of said hook-ring between the heads of said pins and said lugs, substan- 1 tially as shown and described.

The combination of a whilt'letree end of and conlined between said lugs and pins, and a hook )ro jeeting from said ring and terminating in an abrupt angle-point conforming to and bearing against the inner surface ol said beveled flange.

ln testimony that T Clililll the foregoing l have hereunto set my hand at Raeine, in the eluuty of liaeine and State otf Wisconsin, in the pi e'aence olf two witnesses. 7
