ANT-IRATTLER FOR THlLL-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 596,562, dated January 4, 1898.

Application filed November 7, 1896. Serial No. 611,871. (No model.)

To all whom it may concern.-

Be it known that I, ALFRED H. WoRREsT, a citizen of the United States, residing at Lancaster, in the county of Lancaster, State of Pennsylvania, have invented certain Improvements in Antirattlers, of which the following is a specification.

This invention relates to improvements in that class of antirattlers used with thill-couplings, and it is a modification upon an antirattling thill-coupling for which I have made application for Letters Patent of the United States, filed July 28, 1896, Serial No. 600,796. I11 the antirattlin g thill-coupling forming the subject-matter of said application a speciallyconstructed. thill-iron and a special clip for the axle are required.

The object of this invention is to apply the principles shown and described in said preceding application to a thill-iron and clip of the ordinary construction.

The invention consists in the construction and combination of the various parts, as hereinafter fully described, and then pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure l is a front perspective view of the device for supporting and clamping the bearing-block in place; Fig. 2, a front perspective view of the bearing-block, and Fig. 3 a perspective view of the cam-lever. Fig. 4 is a side view of my improvement, showing the same attached to a thill-coupling and the bearing-block clamped in position; Fig. 5, a top plan view of the same; Fig. 6, a horizontal section on broken line 6 6 of Fig. at, but showing the same with the thill-iron detached; Fig. 7, a vertical section on broken line 7 7 of Fig. 5, showingthe antirattling bearing-block clamped in position; and Fig. 8, a similar section, but showing the parts in the position occupied thereby before said block is clamped in position. Fig. 9 is a front view of the device as shown in Fig. 1, the thill and thill-iron being cut away from the eye of the latter; and Fig. 10, a bottom plan view of the device for supporting and clamping the bearing-block in place. Fig. 11 is a sect-ion of the arms of the frame and the clip-bar on broken line 11 11 of Fig.

through- Referring to the details of the drawings, A

indicates a vehicle axle; A, an ordinary thill-coupling clip, having the jaws a; B, a thill-iron; Z), the eye of the thill-iron, through which passes the bolt coupling together the thill and said jaws a, and b the couplingbolt. The clip A is secured to the axle by means of the ordinary clip-bar A and nuts a The frame supporting the antirattlingbearing-block and the cam-lever comprises horizontal arms D, extending back beneath the axle and having their rear ends connected by a cross-bar d, angular in cross-section, so as to form therein an internal shoulder 61, and havin g its upper face bearing against the rear nut a to prevent the unscrewing of the same; cheeks D on arms D that embrace the front nut a and prevent the unscrewing thereof; posts D formed on cheeks D and-passing up between and adjacent to, respectively, the clip-jaws a and having their upper ends connected by a cross-bar 61 provided with outwardly-extending shoulders (1 that bear on said jaws a between the eyes a of said jaws and the body of the clip, and seats D that form bearings for the journals 6 of the camlever. Posts or checks D support the whole appliance for preventing any rattling, the upward pressure from the seats D thereof, which supports the bearing-block, being in a direct upward line, with the cam bearing against the chill-iron. The spring bearing on the cam that influences the action of said cam does not support any weight from the thill-eye.

The cam-lever E comprises a cam E, having on the sides thereof journals 6, that engage seats D a downwardly and rearwardly extending arm 6 on one of said journals 6, formed at right angles therewith and lapping the outer face of the adjacent seat D, the swinging end of arm e being turned inward at approximately right angles therewith and extending beneath arms D of the supportingframe, the inturned extremity of arm 6 having thereon and at an approximately right angle therewith a drooping handle E that extends beneath the axle and wherewith the cam is operated; an outwardly and upwardly curved arm E forming a prolongation of arm 6 and having thereon a rearwardly and upwardly extending lip 6 that when the parts are in their normal positions engages the outer face of the head of coupling-bolt b and prevents disengagement of the same from the parts it connects, and a lip e on the free end of the journal 6 opposite to that carrying handle E said lip 6 being parallel with arm 6 and bearing against the outer face of the adjacent seat D F indicates an antirattling bearing-block. This block has a projection f beneath, which engages between seats D said projection having a concave bottom face f, that rests on cam E in front of posts D Said projection also forms shoulders f on the ends of bearing-block F, which lap and bear upon the outer portion of said seats D The top of this bearing-block is concave in cross-section, as shown at f Fig. 2, and on the center of the rear side thereof is a rearwardly-extending tongue F, that projects back between posts D The lower portions of posts D are upright, and on the inner edges of said upright portions are vertical lips 61 that engage grooves f in the sides of tongue F. Above lips d the upper ends 01 of posts D are curved backward and upward, so as to form concave front faces therein to form a suitable socket for the reception of the eye I) of the thill-iron. The filling-block is put in place by lowering it onto the cam E from above and so that grooves f engage lips d on posts D Between the arms D of the frame is a flat double-plate spring G, the rear end whereof takes under shoulder d of cross-bar d, whence said spring extends forward over a cross-bar d, connecting the lower edges of said arms D between cross-bar d and checks D to and beneath cam E, against which it bears with an upward pressure. The front end 9 of the spring G is narrowed to'conform with the narrowed channel between cheeks D.

NVhen in its normal position, binding bearing-block F against eye I) of the thill-iron, the front slope e of the tongue e of cam E bears against the bottom of the downward projection f of bearing-block F, the swell e of the cam projecting downward and backward and having the lower curve 6 thereof bearing on spring G, whereby, as the contacting surfaces of the filling-block and of the eye of the thilliron wear away, the pressure of said spring G on tongue e revolves the cam and forces the filling-block up the slope of the swell of said cam and retains said fillingblock in close contact with the seats of the thill-iron.

Originally the parts forming the eyes D are extended horizontally, or approximately so, as shown at lines D, Fig. 13, but in assembling the parts the journals 6 of the camlever are placed on said parts adjacent to posts D and then the ends thereof are bent or riveted around said journals. In attaching my device, the bearing-block being in place on the frame, the thill is detached from the axle, and between the jaws a of the clip A the arms of the frame are inserted, with shoulders d resting on said jaws, between the eyes thereof and the body of the clip. Then, if it has not been done before, the camlever is turned so that lip e uncovers the bolt-holes in the eyes of said jaws a, as shown by broken lines a in Fig. 4. The eye of the thill-iron is inserted between jaws to and there secured by the coupling-bolt b, when the handle E of the cam-lever is forced back beneath the axle, pressing the bearing-block up against the eye of the thill-iron.

In Fig. 5 a nut 60 is shown on the threaded end of coupling-bolt b; but said not is not necessaryyas the bolt is held in place by lip 6 In many ways safety is added to a thillcoupling with which this device is used. When the eyes of the thill-irons are inserted between the jaws of the clip, that one to be last coupled is upheld by the bearing-block beneath it while the other is being connected. The nuts a securing the clip on the axle, are prevented from loosening; the couplingbolt is prevented from working out of place; and the bearing-block is automatically forced to take up the wear between itself and the eye of the thill-iron.

As will be understood by the specification, this invention adapts the cam and the spring actuating the same, described in the prior application before mentioned, to a frame removably connected with the clip, whereby by the interposition of a bearing-block said cam and spring can be employed as an antirattler for a thill-coupling of the ordinary construction, which could not be done with said cam and spring and their connections, as shown and described in said prior application.

I do not restrict myself to the details of construction herein shown and described, as it is obvious that many alterations may be made therein without departing from the principle and scope of my invention.
