PATENT OFFI I SPECIFICATION forming part of Letters Patent No. 376,806, dated January 24, 1888.

Application filed June 3, l8l. Serial No. 240,135. (No model.) i

To all whom it may concern:

Be it known that we, J AMES MAOPHAIL and FRANKLIN M. NEEDHAM, citizens of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented a certain new and useful Improvement in Hooks for Singletrees, of which the following is a specification.

This invention relates to the manner in which the hereinafter-described singletreehooks are secured to singletrees.

The object of this invention is toproduce singletree-hooks of the simplest possible construction, that can be securely fastened to singletrees by simply driving the ferrules of said hooks upon the ends of the same.

Referring to the accompanying drawings, which form a part of this specification, Figure l is an isometric view of our improved singletree-ho0k. Fig. 2 is a like? view of the same secured to a singletree. Fig. 3 is a back side View of the parts shown in Fig. 2. Fig. 4. is a view ofa section of the singletree-hook and its singletree through the dotted line as w of Fig. 2. g

Like letters of reference indicate corresponding parts throughout the several views.

.A represents a ferrule provided with an eye, A, projecting transversely forward from the outside of the same.

A representslugs preferably nearly triangular in form and projecting from the outer end of the ferrule A in a direction substantially parallel to the axis thereof.

A represents a wedge included lengthwise between the free ends of the lugs A and ex-v tending inward edgewise in the direction of the longitudinal center of the ferrule A.

A represents spurs projecting fromthe outer end of the ferrule A and converging toward the axis thereof.

B represents a singletree-hook proper connected with the eye A of the ferrule A by means of a counterpart eye, B; The ferrule A, eye A, lugs A, wedge A and spurs A are integral, and can be most advantageously constructed of cast-iron made malleable.

C represents a singletree.

To fasten the singletree-hook to a singletree, rest one end thereof on any anvil, block, or

other firm substance, slip theopen end of the ferrule A upon the other end of the singletree, and strike one or two vigorous blows uponthe ends of the lugs A and back of the wedge A. As the wedge A enters the end of the singletree 0, the curved sides of the semicircular halves 0 thereof will be .pressed outward against the points of the spurs A,. which 'will thereby be forced into the singletree, as shown in Figs. 3 and 4.

Obviously a ring may be used in place of JAMES- MAOPHAIL AND FRANKLIN-M. NEEDHAM, or RooKFoau ILLINoIs.

the hook B,.and our improvement applied to i neckyokes, &c., as successfully as to single trees.

t We claim as new and desire to secure byLetters Patent- I v 1. In a singletree-hook, the combination,

with the herein-described ferrule, of the wedge connected therewith and extending inward edgewise in the direction of the longitudinal .wedge are formedand used in a single piece, as herein shown, substantially as set forth.

"center of said ferrulewhen said ferrule and 2. The combination, with the herein-d'escribed ferrule having lugs projecting from the outer end thereof in a direction substan tially parallel to the axis of said ferrule, of a wedge included lengthwise between the free ends of said lugs and extendinginward edgewise in the direction of the longitudinal cen ter of said'ferrule, and the spurs projecting from the outer end of said ferrule and converging toward the axis thereof, substantially,

as described, and for the purpose set forth.
