To all whom it may concern/:f a Be it known that we, WILLIAM V.

GOTT and HENRY OHARA, both ofthe city of St. Louis, inthe State OfMissouri, have .in- `vented a certain new and useful Im`prove`` ment in Car-Couplers, ofwhich the' following l is afull, clear, and exact description, reference being .had 4to the accompanying draw- \ings, forming part of this specification. l n `Our invention relates to certain improvements imautomatic car couplers, ofthe class Shown, described `and ,claimed inthe `patent issued to the Keystone Car Coupler Company, dated November19`,18S9,-No. 415,309, and the `reissue patent to Lorraine and Aubin,"No.` 10,941, dated 'J une 26, 1888. y a a Our invention consists in features of novelty hereinafter fully described and pointed out in the claims. n a.w` Figure I is a plan view ofone of the drawheads, showing the hook in its closed or using position. Fig. II is a horizontal section, taken on line II-II,`Fig. III, and showing the hook in its open position. Fig. III isV an end view of one of the draw-heads,lwith thecoupling hook removed, and showing the trunnion bearings and abutment; also the ledges inside of the draw-head near the front end. Fig.' IV isa side view, part in section, showing the position of the hook when locked in the draw-head, also the position of the pin eX- tending down through the perforated trunnions, also the perforation in the coupling hook, also the rib ,on the upperl side of the inner arm that guides thelooking pin, also the ledges in' the drawhead, and also the rib on the lowerside of the inner arm of the coupling hook. Fig. Vis avertical section,taken on line VV, Fig. I, and showing the position of the pin in the perforated trunnion bearings, and also the hook and position of the trunnion bearing in the perforated recess coupling hook. Fig. VI `isa detail seotion,A showing the abutment` and coupling hook when closed and locked, ready for tran-` sit. Fig. VII is a similar view, showingthe coupling hook when in its opened position. Fig. VIII is a section taken on line VIII- VIII, Fig. IX, showing the hook in top view and in its locked position, and showing its relation and bearings on the perforated trun- WOL? i locking pin; a the hook removed from the draw-head. Fig.

flanges fitting against the trunnion nion.` Fig. IXisa section taken online IXV IX, Fig; VIII and showing the positionof the inner arm of the hook withrelation to the Fig. X is a perspective viewof '55 XI is a perspective viewof the lower `half of onefof the 'drawheads i Referring to the drawings,l represents one 6o an automatic car coupler, intended to con` nect with a draw-head and hook correspondingly formed. "Ilhe hook has a perforated hub 3 having a recess 4i at each end, forming 6 represents the inner arm of the hook having an upper rib 7, beyond which is a table portion 8 on which the lower end of the locking pin rides as the hook` is opened and The drawhead is provided with perforated 7 trunnion bearings 10 between which the hub 3 tits, as shown clearly in Fig. V, and ll represents abutments extending from the trun-` nion bearings to the' vertical wall 12 of the draw-head, (seeFig. XI.) t Whenthehook is in place` a pin 13 is passed through the perforated hub and trunnion bearings, and the flanges 5 fit against the verticalfaces 14 of thetrunnion bearings and limit the opening 8o and closing movement of the hook by their ends 15 impinging, respectively, against the inner and outer vertical faces of the abut- 4ments` 11, see Figs. VI and VII. yThese n bearings, 85 take all strain off the pin 13 when the hook is in its `closed or using position, as will be clearly seen in Figs. VI and VIII, andthey Valso serve as an additional bearing surface locks the hook. As the hook opens and roo y closes the outer vertical walls of the ribs 7 and 9 bear against the inner vertical walls of a ledges 17 in the draw-head, Which assists in the guiding of the hook, and, When the hook is in use, affords strength and rigidity to the parts. v

We claim as our inventionl. In a car coupler, the combination ofva coupling hook, and a draw-head provided with perforated trunnion bearings reinforced by an abutment extending from the perpendicular Wall of the drawhead to the trunnion bearing; and in combination therewith, of a common gravity vertical moving locking pin,

resting upon theinner arm of the hook, when open, and riding on said inner arm When the hook is being closed.

2. In acar coupler, the combination of a coupling hook provided with a perforated and recessed hub and ribs on its inner arm, and a dravvhead provided with perforated trunnion bearings connected by abutments extendingto the perpendicular Wall of the drawhead, ledges in the throat of the draw head, and a gravity vertical moving locking pin, resting upon the inner arm of the coupling hook when open, and riding upon said arm when the hook is closing.

3. In a car coupler, the combination of a coupling hook, provided with a perforated recessed hub, ribs on theinner arm of the hook, and a drawhead provided with perforated trunnion bearings connected by abutments to the perpendicular Wall of the drawhead, ledges in the throat of the drawhead, a pin passing through the perforation in the trunnion bearings, and a perforation inthe coupling hook hub, and a gravity vertical moving locking pin resting entirely upon the inner arm of the coupling hook when open, and riding on said arm When the hook is being closed.
