To all whom it may concern:

Be it known that I, ELI H. Jaxxnr, a citizen of the l'nited States. residing in Fairfax county, State of Virginia, have invented new and useful Improvements in Car-Couplings of which the following is a specification.

My invention'relates to car couplings of the Janney type, and has for its object to provide certain improvements over the construction disclosed in an applicationfiled by me June 18. 1906, Serial No. 322,331. as will be hereinafter more definitely described and claimed.

-- In the accompanving drawings: Figure 1 is a' perspective view of my improved con- J and partly broken away. Fig. 3 is a vertipling, showing an improved means for operatiug'the locking pin. Fig. 2 is a central vertical longitudinal. sectional view, the locking pin being shown partly in elevation cal transverse sectional view taken just in front- 0f the locking pin, showing said pin in full lines in its lowermost or locking pqsitiou, and in dotted lines in the lock-set pothe coupling hook being swung open and the locking pin being shown raised to the highest position it will assume when lifted by said coupling hook. Fig. 5 is a central horizontal sec ional view, the coupling book being shown in plan. and the draw head being partly broken away to show underlying parts. Fig. 6 is a view similar to Fig. 2, but looking in the opposite direction, the

locking pin and coupling hook being re-- moved. Fig. 7 is an enlarged detail perspective view of the locking pin. Fig. 8 is similar view of the wording hook.

slight incline upward and forward, as best seen in Figs. 3 and 4. The lower face of said recess 8 18 formed with a cam surface 12 insurfaee 9 and having its upper end projecting beyond the side face of'the pin. As seen in Fig. 2, the upper portion of said cam surface 12 is inclined downwardly from front. to rear at 13. Below the recess 8 in the pir 7 is another recess 14, having its upper edge inclined upwardly and inwardly at 15 to engage a cotter pin 16 removably located in the draw-head, said cotter pin performing the function of supporting the locking pin in the lock-set position. The tail of the .eoupling hook 4 is reversely inclined on its uppe: and lower surfaces at 17 and 18 to correspond with the inclines 9 and 12 on the lockin-r pin. the lower incline 18 being also inclined at 19 to correspond with the incline 13 on the pin 7. as shown in dotted lines in Fig. 2 said incline 19 lying parallel in said figure with the incline of the meet- 1 ing edge 11 of inclines 9 and 10 on the locking pin 7.

Referrin to Fig. 2, it will be seen that the rear will of the apertures 5 and 6 in the drmv-head is slightly concaved to correspond with a similar convexity 20 on the rear face of the locking pin 7 the object of the same! being to cause said pin, when lifted by the movement of the coupling hook to the closed position, to hug said eoncaved surface, wherebv, when 1e eased by said coupling hook, it Wlll drop free from the lock-set )in 16 to its locking position. The cam sur ace or incline 12 of locking pin 7 is projected at its lower end to the right, said projection performing the double function of an anticrecping device and a means for throwing the lower end of the locking pin to the left beneath the tail of the coupling hook. Further, said locking pin is provided with the incline 22, which, when the locking pin is in its lowermost position, engages a similar incline .23 formed in the lower aperture (3 of the draw-head, to impart an initial liftto the locking pin when contacted with by the coupling hook tail in its movement to the closed position.

All of the above arts being constructed to operate as descri ed in my application hercinbefore referred to, further detailed description of the same is deemed unnecessary.

clining in a direction the reverse of cam,

In my improved construction the projec tion to the right of cam surface or incline 12 aids in performing still another important function, as follows: In this class of conplings the dropping of the locking pin to its lowermost position when the coupling hook is opened has been )reventcd heretofore by extending the tail of the coupling hook so that itwill act as a support for the locking )in at all times except when said coupling hook is in its closed position. Applicant accomplishes this result without employing the extension on the coupling hook tail by providing a recess 24 in the side wall of the draw-head opposite to the coupling hook tail when the latter is in its closed position, said recess being inclined forwardly at its lower end at 25 and merging into another incline .26 at a right angle thereto, said latter incline overlying the cotter pin 16 that constitutes part of the l ckset mechanism, as bestseeu in Figs. El, 4. 5 and 6. Now, when the locking pin 7 is in the lock-set position, as shown in dottett lines in Fig. 3, and the coupling hook begins to move toward the.open position, the tail ofsaid coupling hook, by its contr with the incline 10 on said locking pin, will raise said locking pin to disengage it from the lock-set, and will at the same time force the lower end of said locking pin to the right,

so that, when the edge 11 on said locking pm comes in contact with the coupling hook tailsaid locking pin will have assumed the position shown in Fig. 4, with theprojec y" of both the inclines 26 and 27, as it. will be tion of its cam surface-or incline 12 lying in the recess 24 m.the draw-head, it being apparent that the movement of the locking pin above described is permitted initially 40 by thcsliding contact between the inclines :26 and .27 on the draw-head and locking pin, respectively. Now, as said locking pin is released by the further movement of the coupling hook tail toward the open position, it will drop, but, being guided by the engagement of the projection of incline 12 with recess 24, the under inclined surface 27 of the former will ride forward on the incline 25 and from thence onto the incline 26. which will cause the aperture 14 in said "locking pin to again engage the cotter pin n16, thereby supporting said locking pin in the lock-set position. It is desirable that this seating of the locking pin on the lockset shall also occur when the coupling hook is thrown open by lifting the locking pin until the incline 12 thereon contacts with the incline 1Son the coupling hook tail, and this result is insured by providing an incline 6 28 on the side of the locking pin 7, and a.

eor'res onding incline 29 in the draw-head 2, suit inclines contacting as the locking pin a preaches 'itshighest limit of movement, w ich forces the lower end of said locking 6 pin to the right, so that the projection of incline l2 thereon will engage in the recess 24: under this movement, and, when the locking pin is released to drop, the inclines :25 and 26 will guide said locking pin to cause it to fall onto the lock-set.

It is desired that when the locking pin 7 is lifted to throw open the coupling hook, the lower endJof said lOClilXl" pin moye to the right to.follo\v the coupling hook tail in its opening movement. This function is performed by my inclines 28 and 29, and by reason of their location intermediate the length of the locking pinfthis movement of the lower end of the locking pin is accomplished by means of smaller inclines than is necessary when said motion is imparted from the lower end of. the locking pin. It will thus be seen that add inclines perform the double function of cansingthe lower end of said locking pin to follow the coupling hook tail in its opening movement, and of causing said locking pin when released to drop onto the lock-set. By these means I provide for the seating ofthe locking pin on the lock-set whenever the coupling hook is opened, the result being that on the return of the latter to the closed position it is necessaryto lift the locking pin only a slight distance, thereby practi rally accomplishing the result heretofore obtained byextending the tail of the coupling hook to form a locking pin support during the (Hill '0' open movement of said couplinghook.

I do not wish to. confine myself-to the use evident -that either one of the same may be dispensed with and the desired result still obtained, though possibly not in so satisfactory a manner. The incline 1:2 on the locking pin is projected to the left to more surely engage with the inciine 18 on the coupling hook tail when it is desired to throw open the coupling hook by means of said locking pin, this operation being aided by 'the contact of extension 21 of incline 12 on the locking pin with the drmwh'ead. Now, to still further facilitate this result, I have projected the incline 18 on the coupling hook tail to the right beyond the engaging face of the coupling hook tail with the locking pin, as shown at 30, the result being that. the area of initial contact between tlte inclines 12 and 18 is correspondingly increased. and the initial opening movement of the coupling hook thereby facilitated.

In Figs. 1 and 2 I have illustrated an im-- ioo if a

- oral movement. of the link 33, required because of the lateral movementol the drawhar in rounding curves, said construction permitting the link 33 to remain hllllSlfllltially vertical in any position of the drawhead, whereby the locking pin may bo' readily operated on the sharpest curves. b'aid link 33 is pivoted to the locking pin between two cars to maintain said link substantially vertical. single connecting link in place of the the locking pin, 1 am with clevises on top of the locking pin and on the crank rod, thereby materially sine plifying the construction of this part. further important :ulvantage obtained by employing the single elongated link 33 is that by means of the same the locking pin t may at any tune he thrown oil the lockset when, for instance, it has been so set by mistake. Thus, with the locking pm Hi the T set. under any opening nuwement of suit By employing this usual chain eonnectingthe' crank rod with enabled to dispense lock-set position, as shown in dotted lines in Fig: the link 33 will assume the position. shown in dotted lines therein, with the crankedportion ill of crank rod Ill po- Slot crank rod ill is held against further downward movement by the contact of -said cranked portion with the car sill, shown Ht 2 dotted'liues in Fig. L, said cranked portion will act as a tulcrum for said link, and upon pressure being applied, or a blow struck,

to the upper end of link lil in a rearwaml direction, said link win act to lil't and force the upper endol' the locking pin T forward, tnereny on-mg its lower end rearward and out. of its engagement with the cotter pin H3, and thus releasing said locking pin from the lock-set position.-
