THlLL-COUPLING.
SPECIFICATION forming part of Letters Patent No. 589,063, dated August 31, 1897.
Application filed'J'uly 28, 1896. Serial No. 600,796- (N'o model.) I
following is a specification.
This invention relates to improvements in that class of couplings connecting the thills or tongues of vehicles with the axle; and the objects of the improvements are, first, to provide a coupling by which thills or tongues can be detachably connected with the axle without the use of screws or bolts; second, to construct the coupling so that thills or a tongue can be connectedwith or detached from the axle more easily and expeditiously than can be done-with the ordinary bolt-coupling, and, third, to produce a thill-coupling cheap and simple in construction. and in which each member or part is detachably connected with the other members or parts.
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 1 is a side view of a coupling embodying my invention, the thill being secured in the coupling; Fig, 2, a similar view showing the coupling in sec tion; Fig. 3, a side view, the thill being engaged with the coupling, but not locked therein; and Fig. 4, a similar View showing the coupling in section. Fig. 5 is a vertical section on broken line 5 5 of Figs. 1 and 2; and Fig. 6, a bottom plan view, the parts being in the position occupied thereby in Figs. 3 and 4. Fig. 7 is a perspective view of the coupling detached from the connected parts; and Figs. 8, 9, and 10, similar separate views, respectively, of the coupling-frame, of the keeper-plate, shown inverted, and of the camlever. Fig. 11 is 'a vertical section on broken line 1111 of Fig. '7.
Similar letters indicate like out the several views.
Referring to the detailsof the drawings, A indicates the axle, A the thill, and A a clip of ordinary construction surrounding the axle.
B is the coupling-frame, comprisinga clipparts throughbar B and a thill-iron socket; The clip-bar B" takes under the axle, as is usual, and has shoulders b on the back end which bear against the rear face of the axle, being 10- cated on opposite sides of the opening a in the On the front edges of checks D are formed forwardly-extending U-shaped bearings D, the loops whereof depend somewhat below the clip-plate, and the upper ends of the opposite arms 01 of bearings D are connected by crossbars 61, themselves connected by a horizontal plate or web (1 In the loops of bearings D are supported the journals 6 of cam-lever E, and on the outer end of one of these journals is a hook e, that laps the outer face of the bearings, and on the outer end of the other journal is an arm 6 at right angles therewith and lapping the outer face of the other hearing. The swinging end 6 of arm 0 is turned inward at right angles therewith and extends beneath the coupling parallel with the axis of rotation of journals e, the extremity of end 6 having thereon and at right angles thereto a drooping handle E, wherewith the cam-lever is 0perated. The cam E is supported by and between journals 6, the swell e of the cam being uppermost and locking the thill-iron in I the socket, as will be explained. W'hen handle extends toward the handle, for a purpose to be explained.
Above journals 6 and between the same and the thill-iron is located what I term, for the purposes of this specificatiomthe keeperplate. The bodyF of this plate extends beneath the clip-plate in a channel formed by lips (1 011 the bottom edges of the clip-plate, as seen in Fig. 11, and is provided with two openin gs f and f that register with the open ings in the coupling-frame, through which pass the arms of the clip, and around the rear openingfof the keeper-plate and on the under side thereof is form ed a boss f The arms of the clip pass through openingsfandf, and the nuts 01, securing the clip-plate and the keeper-plate on the clip-arms, bear against said keeper-plate.
On the ends of the front edge of body F are forwardly-projecting arms F, that pass over and rest on the journals 6 between cam E and the U-shaped bearings D, said arms being raised somewhat above body F.
Each journal 6 is embraced by jawsj' on the bottom of the arm passing over the same, and the under sides of said arms are rounded out between jawsjj to properly embrace the journals. The keeper-plate thus serves to hold the journals 0 down in their hearing, even when the socket is not engaged by the thill-iron.
G indicates the thill-iron, secured to the thill in the ordinary manner and being of the usual shape, but having on the bottom of the inner end a shoulder G, the front face ,1 whereof is so curved as to be adapted to engagement by cam E whereby said thill-iron is rigidly locked in the socket, as fully'illust-rated in Fig. 2.
In the bottom of the keeper-plate and about midway between the clip arms is secured what I call a tension-bolt h, the lower end of which is threaded, and on this bolt, secured by a nut h, is a flat spring ll, composed of two leaves. The inner end of the spring rests on the end of the rear arm of the clip or on the nut securing the same, while the outer end of said spring extends forward between jaws j and beneath the cam, against which it bears. Jawsj are made longer than jaws j, that they may embrace spring II and prevent lateral displacement thereof.
The thill-iron is of such thickness that it fits snugly between cross-bars d and the tops of arms F of the keeper-plate, the shoulder G being narrower than the thill-iron, so as to fit between said arms F, and the flat side 6 of the cam opposite the swell e is reduced that it may fall below the level of the upper edges of arms F when the handle E is thrown forward, as seen in Fig. 4:.
Vhen the parts are in their normal positions, the swell e of the cam engages the curved front face 9 of shoulder G, the tongue 6 of said cam extends back beneath shoulder G, the handle E of the cam-lever also extends backward beneath the coupling, and the front end of spring II bears against the fiat side e of the cam, so as to take up the wear of the cam and the adjacent parts and prevent the disengagement of the cam from shoulder G. To disconnect the thill from the coupling, the handle E is drawn downward and forward until it extends beneath the thill in an approximately horizontal p0 sition. By this movement of said handle tongue 6 depresses spring II and is turned forward in the direction of the handle, leaving the flat side of the cam uppermost, so as to afford a free channel for the passage of shoulder G in withdrawing the thill-iron from the socket. In recoupling, the thill-iron is again inserted and the handle E is turned downward and backward.
For safety, to prevent accidental disengagement of the cam from the shoulder G, the cam is so constructed that it is not entirely disengaged from said shoulder until the handle E has almost reached the horizontal forward position. To disengage the cam entirely from said shoulder, the handle must make fully one-half the turn from the vertical position, as shown by broken lines I, Fig. 2, to the front horizontal position as in Fig. 4:, so that should spring I1 break or weaken and the handle drop the thill-iron would still be locked in the socket. The only strain upon the spring is the pressure of handle E, and this is greatly reduced or taken up entirely by the friction between the cam and shoulder G. The tension of the spring is regulated by the nut 011 tension-bolt h.
The thill iron is provided with a bolt-hole K, so that it can be engaged with an ordinary coupling.
The coupling-frame, the cam-lever, and the keeper-plate are assembled by first inserting the cam through the upper portion of the U-shaped openings, with handle E extending upward, then turning said handle forward, as shown, respectively, by broken lines on and m of Fig. 8, and then lowering the journals into their bearings. After this the arms F are inserted vertically behind the cam-journals and the jawsjj engaged therewith, as shown by broken lines m of Fig. 8, when the body of the plate is revolved upward about said journals and into its place between lips (Z The coupling-frame and keeper-plate are then secured on the arms of the clip.
The application of the principles in my invention are entirely new. I do not, therefore, confine myself to the details of the 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.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
