CAR-COUPLIN G.
Specification of Letters Patent.
Patented Dec. 8, 1908.
Application filed July 8, 1907. Serial No. 382,667.
To all whom it may concern:
Be it known that I, JOSEPH MARTIN OALLJU, citizen of the United States, residing at Chicago, in the county of Cook and State .of Illinois, have invented certain new and useful Improvements in Car Couplers, of which the following is a specification.
This invention relates to car couplers of the type having a pivoted knuckle which swings in the drawhead, and has for its object to rovide an improved knuckle opener and 100 r, which can be operated conveniently from either side and which avoids the use of coupling pins and the like.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a lan view of a coupling head provided with the improvement. Fig. 2 is a horizontal sectional vlew thereof. Fig. 8 is a vertical section on the line 33 of Fig. 2.
Referring specifically to,the drawings, 6 indicates the coupling head and 7 the swinging knuckle, the tail piece 8 of which swings in a recess in the cou ling head, as usual.
9 indicates a ar which is located in said recess and projects at one end through an opening in one side of the head. This bar is slidable lengthwise across the head, on the floor or bottom of the recess in the head, and under the tail 8 of the knuckle, guides for its movement being formed by the front wall of the head and ribs 14 and 15 extending respectively across the floor and the top of said recess. rectly, or it may be connected to operating devices extending to the side of the car. It has in the upper side or edge thereof a recess or cut-out part as shown at 11, which when the bar is moved in one direction allows the tail 8 to swing therethrough, but when the bar is moved in the other direction the solid part thereof moves to position in front of the tail of the knuckle, and so revents said knuckle from swinging open. aid recess 11 produces also a shoulder 12 located on the opposite side of the knuckle from the body of the bar, so that said tail 8 swings in and out between the shoulders at the ends of the rew front of the tail 8, at which time the shoulder 12 strikes against the rear or back side of the tail 8 and swings the same outward, through The bar may be manipulated dithe recess, turning the knuckle on its pivot and opening the same.
The device will couple automatically, as when the coupling heads come together the knuckle is swung back, causing the tail 8 thereof to strike the shoulder 12 and slide the bar 9 to the right, bringing the solid ortion thereof in front of the knuckle tail an forming the lock. This action is assisted or completed by means of an inclined projection 12 on the under side of the bar 9, which projection is properly positioned to slide down the beveled edge 13 at the end of the recess in the bottom part of the head 6. 1 Thus, when the knuckle strikes the shoulder 12, in the act of cou ling, it pushes or throws the bar 9 to the right until the point or lower end of the incline 12 passes over the edge 13 at the side of the head, after which the weight of the parts will cause the inclined projection 12 to slide or settle down over said edge and complete the movement to advance the solid art of the bar in front of the tail of the knuc le. The part 12 after dropping over said edge, will also serve to revent accidental disengagement of the loc after being coupled. Sufficient space is left above the top of the bar to permit lift or movement of said bar when it is moved to the left, for the purpose of unlocking the coupling and 0 enmg the knuckle. The end of the tail 8 o the knuckle is turned or presented forwardly so as to bear directly behind the bar 9, to avoid any lateral pressure thereon which might tend to force the locking bar out of position. As shown, the pressure of the knuckle binds the locking bar against the front side or wall of the recess in which it is held.
I claim:
1. In a car coupler, the combination with a recessed head and swinging knuckle, of a lock bar slidable across under the tail of the knuckle in the recess in the head and having an upstanding rojection engageable in front of the tail of t e knuckle, to lock the same, and clamped thereby against the front wall of the head, when closed.
2. In a car coupler, the combination with a head and pivoted knuckle, the head having a recess into which the tail of the knuckle swin s, said tail being offset at the inner end, of a ocking bar slidable horizontally in the head and across the recess and en aging in front of the offset tail of the knuc e when locked.
3. In a car coupler, the combination of a recessed head having cross guides on the top head having a cross recess therein, a pivoted and bottom of the recess, a swinging knuckle knuckle the tail of which swings into the rehaving an offset tail, and a lock bar slidable 15 cess, and a locking bar extending and slidin the guides across the recess and engageable horizontally across the recessand under able in front of the tail of the knuckle, to lock the tail of the knuckle, said bar having shoulthe same when closed. I ders projecting upwardly on opposite sides of In testimony whereof I affix my signature, the tail of the knuckle and also having a in presence of two witnesses. projection inclined on the under side and JOSEPH MARTIN CALLJU. adapted to slide out the end of the recess Witnesses: when the bar is shifted to locking position.
