CAR-COUPLING.
Specification of Letters Patent.
Patented March 19, 1907.
Application filed 'November 28, 1906. Serial No. 345,431.
To @ZZ whom, it may concern:
Be it known that I, GUsTAF A. HERMANsoN, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Couplers, of which the following is a specification.
My invention relates to improvements in car-couplers, and more particularly to improvements in car-couplers of the Master Car-Builders7 type, having a forked drawhead, pivoted knuckle, and gravity-lock.
The object of my invention is to provide a Master Car-Builders7 coupler of a simple, efficient, and durable construction, composed of few parts, in which the knuckle will be lautomatically thrown open by the lift-ing of the lock, in which the lock may be set in position for coupling and uncoupling, and in which the lock will not be dislodged from its lock-set position until after the knuckle is swung partially open, and in which the lock will be prevented from creeping.
My invention consists in the means I employ to practically accomplish this object or result.
In the accompanying drawing, forming a part of this specification, Figure 1 is a central vertical longitudinal section of the carcoupler embodying my invention. Fig. 2 is a similar view showing the lock in its lockset position. Fig. 3 is a horizontal section. Fig. 4 is a vertical cross-section on line 4 4 of Fig. 3. Fig. 5 is a detail bottom view of the knuckle. Fig. 6 is a detail front view of the lock. Fig. 7 is a detail side view of the lock, showing the reverse side thereof from that appearing in Figs. l and 2. Fig. 8 is a section on line 8 8 of Fig. 6. Fig. 9 is a detail top plan view of a portion of the draw-head, showing the opening for the lock therein.
In the drawing, A represents the! draw- -head; B, the knuckle; C, the pivot-pin, and I) the vertically-movable gravity-lock.
The draw-headAhas the customary guardarm a, pivot-arm a, and an opening a2 in its bottom wall or web conforming in shape to the lower end of the lock and-an opening 0,3 in its upper wall corresponding generally to the cross-section of the lock at its upper end.
The knuckle B has its rear arm or tail furnished with a recess b at its rear end,
l or floor of the draw-head to hold the lock set or in position for uncoupling. The lock set leg d is preferably slightly curved and extends at an angle to the front face of the lock. The lock-set leg of the lock is also provided at the edge thereof adjacent to the knuckle with a knuckle-throwing foot or projection (Z5, adapted to engage the knuckle-throwing cam or incline b2 on the tail of the knuckle and throw the knuckle open when the lock is lifted to the required extent. To cause the lock to be dislodged from its lock-set position after the knuckle has been swung partly open by the further opening movement of the knuckle, I provide the lock with a lockdislodging lip or'shoulder cl and the rear arm or tail of the knuckle at its upper front edge or corner with a notch or recess b3 and a cam or incline b4, the cam or incline being located at the rear portion of the notch or recess, so that the knuckle can swingpartly open-as, for example, thirty or forty per cent. openbefore the cam b4 on the knuckle-tail engages the lock-set-dislodging lip or projection d on the lock, and thus pushes the lower end of the lock backward by the further opening movement of the knuckle, and thereby causes the lock-set leg of the lock to be disengaged from the lock-set ledge of the draw-head. To cause the lock-set leg on the lock to cooperate with the draw-head to prevent the lock from creeping, I provide it with a notch or shoulder d2, whichfits under and engages the adjacent portion 0.5 of the bottom web or floor of the draw-head, through which the lock-set leg of the lock extends.
To properly guide the forwardly-curved lock-set leg into the opening of the drawhead and at the same time through the lower end of the lock, YI provide the lower web or ICO floor of the draw-head, at the rear side or wall of the lock-opening therein, with an inclined projection a, which by engagement with the forwardly-curved lock-set leg forces the lower end of the lock forward as the lock tom web or iloor of the draw-head has a notch or enlargement as, corresponding in shape to the knuckle-throwing foot of the lock for said foot to pass through.
I claim- 1. In a car-coupler, the combination with a forked draw-head, of a` knuckle having a rear arm or tail furnished with a knucklethrowing cam or incline, and provided with a notch or recess at its front corner to permit the knuckle to partially open without dislodging the lock fromits lock-set position, and a vertically-movable lock having a lock set leg adapted to engage a lock-set ledge on the draw-head and provided with a knucklethrowing foot or projection engaging said cam on the rear arm or tail of the knuckle to throw the knuckle open, and a projection on the front side of the lock engaged by the knuckle-tail after the knuckle swings partially open to dislodge the lock from its lockset position, substantially as specified.
2. In a car-coupler, the combination with a draw-head having a lock-set ledge on its bottom web or fioor, of a knuckle and a vertically-movable lock having a look-set leg engaging said lock-set ledge on the draw-head,
and provided with a shoulder fitting under and i engaging the bottom web or fioor of the drawhead to prevent creeping of the lock, substantially as specified.
3. In a carcoupler, the combination with a forked draw-head, of a knuckle having a rear arm or tail furnished with a knucklethrowing cam or incline, and provided with a notch or recess at its front corner to permit the knuckle to partially open without dislodging the lock from its lock-set, and a vertically-movable lock having a look-set leg provided with a knuckle-throwing foot or projection engaging said cam or incline on the rear arm or tail of the knuckle to throw the knuckle open, said lock-set leg of the lock being also provided on its front side with a lock-set-dislodging projection fitting in said notch or recess in the knuckle-tail to permit the knuckle to partially open before dislodg j ing the lock from the lock-set and then endislodge the look-set, substantially as'speci- I 4. The combination with a forked drawhead having a lock-set ledge, of a knuckle having a rear arm or tail furnished with a knuckle-throwing cam or incline, and a vertically-movable lock having a lock-set leg provided at its lower end with a knucklethrowing foot and furnished with a shoulder engaging the bottom web or floor of the draw-head to prevent creeping of the lock, substantially as specified.
5. The combination with a forked drawhead having a lock-set ledge on the bottom web or floor of ythe draw-head, of a knuckle having a rear arm or tail furnished with a knuckle-throwing cam or incline, and a vertically-movable lock having a lock-set leg provided with a knuckle-throwing foot at its lower end engaging said cam or incline on the knuckle-tail to throw the knuckle open, said lock being provided on its front side with a shoulder engaging the surrounding Wall of the draw-head to tilt the upper end of the lock backward and its lower end forward Vto cause its lock-set leg to positively engage the lock-set ledge on the draw-head, substantially as specified. y
6. The combination with a forked drawhead having'a lock-set ledge on the bottoni web or floor of the draw-head, of a knuckle having a rear arm or tail furnished with a knuckle-throwing cam or incline, and a vertically-movable lock having a lock-set leg provided with a knuckle-throwing foot at its lower end engaging said cam or incline on the knuckle-tail to throw the knuckle open, said lock being provided on its front side with a shoulder engaging the surrounding wall of the draw-head to tilt the upper end of the lock backward and its lower end forward to cause its lock-set leg to positively engage the lock-set ledge on the draw-head, said locke set ledge having also a shoulder engaging the bottom web or floorof the draw-head to prevent creeping of the lock, substantially as specified.
7. The combination with a forked drawhead having a lock-set ledge on the bottom web or floor of the draw-head, of a knuckle havin knuclflathrowing cam or incline, and a vertically-movable lock having a lock-set leg provided with a knuckle-throwing foot at its lower end engaging said cam or incline on thel IIO a rear arm or tail furnished with a cause its lock-set leg to positively engage the open before the lock is dislodged from its locl-set ledge on 1the dlaWl-lliead, said loclll lock-set position7 substantially as speoiiied. set e ge havin a so a s ou c er engaO-infr t e bottom web or glooiof the draw-beatiJ tobpre- GUSTAF A' HERMANSON 5 Vent creeping of the look, and said look and Vitnesses: y
