METALLIC HAM E.

SPECIFICATION forming part of Letters Patent No. 433,980, 'dated August 12, 1,890.

Application filed January 28, 1890. Serial No. 338,394. (No model.)

To all whom it may concern:

Be it known that I, FRANK L. CROSBY, a citizen of the United States, residing at Farmer City, in the county of De W`itt and State of Illinois, have invented certain new and useful Improvements in Metallic Hames; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention has reference to improvements in hames, having more special application to metallic haines; and the object of my improvement is to furnish a simple and efli cient means of adjustably attaching the front end of the tug to the haines in such manner that said attachment may be changed vertically, so as to vary or adjust the point of draft at the hame to horses of different sizes or variant conformation of shoulders, and also with reference to the altitude of the rear attachment. I attain this by the mechanism illustrated in the accompanying drawings, in which-- Figure l is a perspective of a metallic hame embodying my invention. Fig. 2 is a front view thereof, and Fig. 3 is a cross-section of the same in the line x a; of Fig. 2.

My invention in this application as adapted to a metallic hame is different from but somewhat analogou s to that shown in United States Letters Patent No. 415,028, granted to me November l2, 1889, for improvements in haines.

In the last-named patent there was shown a Wooden hame,`which necessarily required front and rear plates. In this application, as the hame is designed to be of iron, steel, or some other suitable metal, some of the parts referred to in said former patent may be dispensed with in this invention and the construction thereof be very much simplified. A vertical adjustment of the attached end of the tug is shown in said former patent to be accomplished by a greater number and somewhat'diiferent devices than are required for the accomplishment of the same purpose in this application.

A is a hame of the usual conformation, in-

tegral throughout, and constructed of, iron,

steel, or any other suitable metal. A

B is a slot yformed vertically in the hame A and extending through the same from front to rear from a point somewhat below the locality of the intended `tug attachment to a point somewhat above the latter. The rear portion of the slot B has smoot-h parallel walls C C. In the front port-ion of the slot B is formed a series of recesses D in pairs, one of each pair being formed oppositely to the other in the front walls of the slot B. These recesses may be rectangular in form, or seinicircular, or halfoval, as may be preferred, it being essential only that they shall be of the shape and conformation of the engaging end of the attached tug.

E represents the forward end of the tug, and may be either a plateattached at its rear end to the front end of the tug and projected forwardly through the slot B, or the tug itself may be projected through said slot and suitably furnished with an engaging head F, I

adapted to be received and held by the recesses D.

In the hame A there is formed centrally a vertical series of holes G, located, respectively, in a line with'the prolongation inwardly of the center of the recesses D. A hole H, corresponding in form with the holes G, is formed in the part E to communicate with the holes G in the part E when in place, and through the holes G and H is removably inserted a suitable bolt or screw J. After the head F is drawn back into the recess D the bolt J prevents any casual forward movement of the part E or head F, and thereby prevents said head from escaping from the recess D, in which it may for the time be seated. The hole II is made larger than the holes G and screw J, so that in .use the part E is not in contact with said screw, and therefore does not tend to loosen the latter. The extending of the screw or bolt J through both walls of the slot B also prevents the latter from widening under the pressure from the head F, which might allow the head F to escape. As the draft is entirely upon the head F, all the strength required of the bolt or screw .I is

IOO

simply sufficient to prevent the head F from casual removal from or being shaken out of its seat in the recess D when the trace is slack, and therefore said bolt may be of very slight form and the holes G correspondingly small.

The neck of the part E back of the head F is of the same thickness as the transverse diameter of the slot B. Therefore by the removal of the'bolt or screw J and pressing the part E forward sufficiently to disengage the head F from therecess D the part E may be raised or lowered, as may be desired, and drawn back into any selected recess D, and by the insertion of the bolt J in the hole G of said occupied recess part E may be securely fastened therein.

I do not limit myself to any number of recesses D or to any` special size or conformation thereof, the only purpose o f the same being to afford a seat for the conforming head F on the forward or outer end of the part E.

What I claim as my invention, and desire to secure by Letters Patent of the United States, 1s

The combination of a metallic hame provided with a longitudinal slot through the body thereof from front to rear and with a vertical series of transverse holes through the Walls of the slot, a tug end Within the slot having a head upon its front end, which engages With the walls of the slot, said tug end being also provided With a hole which registers with the holes in the walls of Vthe slot, but of a greater diameter than Said holes, and a bolt or screw through the holes in the Walls of the slot and in the tug end, substantially as described.

In testimony whereof I ahX my signature in presence of two Witnesses.

FRANK L. CROSBY.
