CAR-COUPHNG.

SPECIFICATION forming part of Letters Patent No. 781,949, dated February '7, 1905.

Application filed May 5. 1903. Serial No. 155,765.

To all whom, it may concern:

Be it known that I, ELI H. JANNEY, a citizen of the United States, residing in Fairfax county, State of Virginia, have invented new and useful Improvem'entsin (Jar-Couplings, of 1 which the following is a specification.

My invention relates to car-couplings, and more particularly to that class known as the Janney type, and has for its objects, first, to provide improved means for automatically rotating the coupling-hook to its open position by means of a vertically-movable locking-pin, and, secondly, to provide improved means for setting the locking-pin in the unlocking position and for automatically disengaging it from said set position by the movement of the tail of the coupling-hook. These objects I accomplish in the manner and by the means hereinafter described and claimed, reference being had to the accompanying drawings, in

Y which:

Figure 1 is a proved coupling, showing the same in its open position. Fig. 2 is a detail perspective view of the coupling-hook detached. Fig. 3 isa detail perspective view of the locking-pin. Fig. & is a bottom plan view of the coupling. Fig. 5 is a vertical longitudinalsectional view, the couplinghook and lockingpin being shown in full lines. Fig. 6 is a similar view,

the locking-pin being shown raised and retained in the unlocked position. Fig. 7 is a vertical transverse sectional view taken immediately in front of the locking-pin. Fig. 8 is a horizontal sectional view showing the coupling in the lock-set position. Fig. 9 is a detail sectional view similar to Fig. 7, showing the tail of the coupling in the act of movingto the locked position, the locking-pin being shown partly raised thereby. Fig. 10is a View similar to Fig. 6, illustrating a slightlymodified construction.

Similar numerals of reference denote corresponding parts in the several views.

In. the said drawings the reference-numeral 1 denotes the draw-bar of the coupling, carrying the draw-head 2 of the well-known J anney type, in'which is pivoted, by means of pin 3, the usual coupling-hook 4. Passing vertically through the upper and lower apertures l 4 l l l perspective view of my imslightly beyond the side face of the pin, as

shown in Figs. 3 and 7. The tail of the coupling-hook t is reverscly inclined on its upper and lower surfaces at 11 and 12 to correspond with the inclines 9 and 10. said upper incline l1 merging into a flat surface 13, having a rounded projection 14 centrally thereon, said projection having a flat top surface and adapted to engage a narrow flat surface 15 at the lower end of incline 9 in a manner hereinafter to be described.

Below the recess 8 in the pin 7 is another reccss 16, having its upper edge 17 inclined upwardly and inwardly to engageashoulder 18, formed on the inner fron face of the lower aperture 6 in the draw-head when said pin is raised to the unlocked position, the latter having its upper edge beveled to correspond with that of the upper edge 17 of recess l6,-as shown in Fig. 6. It will also be observed that the lower edge 20 of recess 16 is inclined downwardly and that the front side of the locking-pin 7 below said recess projects somewhat bcyond the vertical surface of said pin above said recess also for a purpose hereinafter to be described. i

Formed in the side of pin 7 and just below the lower edge of the draw-head when said pin is in its lowermost position is an incline l9, adapted to perform the following double function: 'hen the pin 7 is in its lowermost position and the coupling-hook at locked thereby, the traction on said coupling-hook will force the lockingpin 7 to the right, as shown in Fig. 7, thus causing incline 19 to underlie the lower edge of the draw-head 2 and effectually preventing any upward creeping of the locking-pin 7, due to the jolting of the cars while in motion, whereby the locking-pin 7 might otherwise ultimately be lifted suflicicntly to release the coupling-hook 4. The other function of said incline 19 is performed when the locking-pin 7 is lifted to automaticlocatedally throw the coupling-hook 4: to its open poling-hook tail. By referring to Fig. 6 it will be observed that the lower incline 12 on the tail of the coupling-hook 4 is also inclined up: wardly and forwardly and that the coacting lower incline on the locking-pin 7 is correspondingly inclined for a purpose hereinaf:

' ter to be described.

. From the above description the operation of my improved construction will be understood to be as follows: With the pin 7 in its lowermost position and the coupling-hook t open, as shown in Fig. 1, the device is ready for automatic coupling, the rotation of said hook causing cam-surface 11 on the tail thereof to contact with cam 9 on the pin 7, and thus raise the latter until the coupling-hook tail passes the same, when it will drop automatically, and thus lock the hook in its closed position. Now when it is desired to uncouple the pin 7 is lifted, by means of its cord or chain, until the-incline 10 on the pin engages incline12 on the hook, when by reason of the forward and upward incline of the same 'as shown in. Fig. 6, the lower end of the pin will be positively tilted forward, thus bringing the recess 16in said pin in engagement with shoulder 18 in the draw-head when said pin reaches the unlocking position, and thus retaining said pin in this position, sothat the coupling-hook 1 may be turned -t-o its open position, thus permitting the cars to separate. By referring to Fig. 8 it will be observed that the locking-pin 7 has its edge or corner nearest the tail of the coupling-hook L beveled at 2l,and this forward movement of the lower end of saidlocking-pin brings it into the path of movement of the taii of the coupling-hook 4, so that the latter in its movement to the open or closed position will contact with the beveled edge 21 thereof and automatically force said locking-pinbackward again to disengage recess 16 from shoulder 18, thus permitting said locking-pin to drop to its locking position when said coupling-hook has rotated away from engagement therewith. It may happen sometimes, however, that owing to a variation in the castings the tail of the coupling-hook 1 will not be long enough to thus contact with the locking-pin 7, and as it is essential that the latter shall be disengaged from the shoulder V 18 and drop to its locking position when the coupling-hook 4 is swung to the closed position I have provided the following means for insuring this result: The locking-pin 7 when in engagement with'the shoulder 18 has the lower edge of its incline 9 slightly below the upper edge of the rounded projection 14 on the tail of coupling-hook 4, and the latter in its movement to the open position will contact with its projection- 1a with the flat surface 15 on the locking-pin 7, thus slightly lifting the latter to disengage it'frorn the shoulder 18. By referring to Fig. 6 it will'be'seen that' the fiat surface. 15 on the locking-pin is also inclined upwardly and out wardly, so that this contact will take place only at a point near the inner end of said flat surface or. at the center of gravity of said locking-pin,- thus causing said'locking-pin to resume its vertical position when lifted from engagement with the shoulder 18, and per- 18 when released by the coupling-hook tail. it will be further obse. ted that as the flat surface 15 'on the locking pin, passes out. of contact with the projection 14; n the coup- :ling-hook tail during the movement of the latter to either the locking or the unlocking position it will first drop onto the fiat surface 13 on the coupling-hook tail, and said ,pin will thus be maintained momentarily in the vertical position and will at the same time have dropped sufiicie'ntly to bring the upper edge 17 of its recess 16 below the shoulder- 18 on the draw-head, so that engagement of the two will be impossible. fore, that with the pin 7 in the lock-set position a movement in either direction of the tail of the coupling-hook beneath the surface 15 on the pin 7-will result in the latter being It follows, there I nittin'g it to drop free from said projection lifted and disengaged from the shoulder 18, a

so that it will drop to the locking position. It will readily be seen that, if desired, the

projection 18 may be located in the rear face of the lower aperture 6 of the draw-head and the recess 16 correspondingly located in the rear face of the locking-pin 7. for by reversing the forward and upward incline of incline l2 and similarly reversing that of incline 10 the result will be that when said inclines contact as the locking-pin 7 is lifted the lower end of the latter will be positively forced backward instead of forward, thus insuring the engagement of recess 16 with projection 18, as shown in Fig. 10. With this construction the flat surface 15 of the lockingpin wili'be inclined upwardly and inwardly instead of upwardly and outwardly, the result being that as the coupling-hook tail passes beneath said flat surface 15 the consequent slight lifting of the locking-pin 7 will result in the lower end of the latter being tilted forward away from engagement with the projection 18, and thus causing the locking-pin to fall to itslowerniost position.

It will be observed that the inclining or beveling of the engaging face 17 of recess 16 and the shoulder 18 will insure their engagement better than if said faces were flat, and

'willeifectually prevent their accidental disengagement.

In order to positively rotate'the couplingh ok-4 to itsopen position by means of the 3 locking-pin 7,1.have provided the inclines 10 and 12, operating as follows: \Vh n the coupling-hook is locked, but not engaged with another coupling-hook, the lifting of lockingpin 7 will cause the projecting upper end of incline 10 thereon to engage the incline 12 on the tail of said coupling-hook,and the fur: ther lifting of said locking-pin necessarily rotates said coupling-hook to its open position in a manner readily understood: .In order that this engagementof said inclines may be insured, l have provided the incline 19 on the opposite side of the locking-pin 7, which by its contact with the lower edge of thedrawhead as the locking-pin is raised forces saidlocking-pin toward the tail of the couplinghook, as seen in Fig. 7. So, also, in order that while the pin 7 is being lifted to throw the coupling-hook open the vertical face of the recess 8 therein may be out of the path of travel of the coupling-hook tail during its rotation to the open position, so that any binding of the parts may be prevented, 1 have provided the inclined lower face 20 for the recess 16 and have projected the front face of the locking-pin 7 below said recess, the result being that as said pin is lifted said face 20, contacting wi the lower end of pin carry said pin out of the path of travel of the tail of the coupling-hook. Furthermore, this positive backward movement of the lower end of the pin 7 will permit said ,pin when released to drop freely to itslowermost position without danger of its engaging projection 18.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a car-coupling, the combination with the draw-head, of a coupling-hook pivoted therein and having inclines in reverse directions on the upper and under sides of its tail, and a vertically-movable locking-pin for said coupling-hook on the tail of ti poses set forth.
