ASPECIFICATION forming part of Letters Patent No. 258,039, dated May 16, 1882. Application ileddanuary 16, 1882. (No model.)

To all whom 'it may concern Be it known that I, NVM. L. EVERIT, o New Haven, in the county of New Haven and State ot' Connecticut,haveinvented a new Improvement in Gar-Couplings, and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1,a side view; Fig.2, a longitudinal central section Fig. 3, a vertical section cutting in front ot' the locking-lever; Fig. 4, a transversesection through t-headjusting-screw.

This invention relates to an improvement in the car-coupling for which Letters Patent ot' the United States were granted to me dated October 5, 1880,'N0. 232,953. In that patent the lever which locks the bolt after the link has been introduced was hinged upon one side ot' lthe head, extended across in front of the bolt to the opposite side, where it was hung to a latching-lever, so that when the latch was disengaged it would raise that end of the lever and bring it up iu front ofthe bolt. This gave to the locking-lever a vibratory movement, it turning on a pivot or fulcruin at one end, and necessitates a bolt to make that pivot. In practiceI find such bolts or hinged connections to be objectionable. I

The object of my present invention is principally to overcomethis objection and raise theV lever or bar bodily upward, instead of a vibratorymovement; anditconsistsin arranging the bar upon inclined seats, and so that when the latching-lever is disengaged` it will draw the locking-bar toward that side and up the inclines, raising it bodily in front ot" the bolt; and it also consists in adevicefor adjusting the coupler so as to engage cars of widely-` Thus, unless preveuteththe bolt will be turned forward by drawing upon .the link unt-il the link will escape from the bolt, as indicated in broken lines, Fig. 2.

Below the mouth B, and forward of the bolt, the transverse locking-bar F is arranged. This bar, instead of being hinged at one side, as in my previous patent, is constructed upon its under side with two inclines, b b, and the seat in which it rests in vits normal condition, as

seen in Fig. 3, is constructed with two corresponding inclines or shoulders, d. The bar extends across to the opposite side, where itis hung to the lower end of the latch-lever G. The said latch-lever G is arranged to swing upon a pivot, c. It is engaged with the bar F by a stud,f, on the latch-lever working ina slot, h, in the end of the bar. The latch-lever G is engaged at the upper end by a latch, H, hinged uponthe opposite side, as at t', so as to engage a shoulder, Z, on the latch-lever' when the said latch-lever is turned into its upright position, as seen in Fig. 3. In this condition the bar F lies below the bolt D, and so that the bolt will swing free of it to permit thelink to be drawn out. The stud f' on the lever Gr is eccentric to the pivot c or center of motion on which it turns. Hence when the lever Gris dropped, as indicated in broken lines, Fig. 3, it turns and draws the bar F toward it. The bar riding up the inclines rises bodily upward, and so as to bring it in front of the bolt, as seen in broken lines, Figs. 2 and 3.

The upper end of the bolt D is made camshaped, as at f, so that when the link E is forced inward and turns the bolt, as seen in Fig. 2, the cam-shaped end of the'bolt strikes the latch H and lifts it, as indicated in broken lines, Fig. 3. In thus rising, the back of the latch, as its nose passes from the shoulder l, strikes an incline, m,on the lever G above and forces it away until it has passed its center of gravity. Then theleverGrfalls ofitsown weight and raises the bar F, as before described, into its position in front of the bolt, and thus holds the bolt within the link and prevents the link from beingdrawn out. When it is desired to disengage the link the lever G is turned up, the latch H automatically engaging with it, as

` seen in Fig. 3, which causes the bar F to fall down the inclines and release the bolt, as before described.

IOO

2 sesame vThis is usually done by means ot' bent links,

which occasion little inconvenience it' they happen to be at hand, but they are seldom so readily to be found.

To adjust the coupler to different elevations I arrange a yoke, L, across beneath the body of the coupler, and through that is an adjusting-screw, l), upon which the coupler will rest.

.Then by turning the screw in one direction or the other the coupler may be raised or lowered accordingly, and thus the coupler is readily adapted to other couplers of ditt'erent elevations Without the change ot' links.

What I claim as an improvement on my Patent No. 232,953 is- 1. The combination of the bolt D, the latching-lever G, and its latch H with the bar F, arranged transversely across in front of and below the bolt, constructed with inclined seats below and engaged with the said latch-lever Gr, so that asthe said latch-lever Gr is turned in one direction it will dra-W the bar towardit and up the inclines to raise the bar bodily, and in the opposite direction permit the bar to fall down the inclines, substantially as described.

2. In acar-eoupling, the yoke L and adjusting-screw P, for the adjustment of the elevation ot' the coupler, substantially as described.
