April l, 1958 A. S. NOBLE LOCK FOR SLIDING DOORS OF RAILWAY CARS Filed NOV. 25, 1954 `LOCK'FOR SLDHNG DQRS-GF RAILWAY 'CARS Albert S.

`fIt is :an lobjectof .this `invention .to .provide locks for sliding doors of railway cars which shall .be .capable of .compensating forinaccuraciesiof vlapplication of .the locks.

rtrnfurther object isrto provide :locks .for slidingdoors :of `railwayvcars which 'shall be -capable of compensating .-for shifting of the .locks tafterfapplication.

Aifurther Objectis .toprovide-locks of lthe hasp 'and pin .'t-ypeufor sliding `.doors off railway cars wherein vthe locks shall 'be so vconstructed that Ethe .hasp can Ybe .projected :or t retracted Vrelative Ato the pin.

:A v.further :object :is to provide lo'oks for sliding .doors *of rail-way Vcars rvso .constructedithatzthelocking' relationship of ythe locks vmay the simply :and .properly lestablished and subsequently.y restored withoutremovingthe .locksfrom'the cars or modifying the locks.

Other objectsof the invention will hec'orne clear as- Y the description ithereof proceeds.

`ln the .drawings forming part of this specification: .Figli is --an elevation of alock'embodying"theinstant .invention applied to a s'lidingdoory of va railway car, the

`door "being shown fragmentari'ly.

"Fig 2is a horizontal section taken on line 2 -2 of Fig. l.

Fig. 3 is a View similar to Fig. l showing the hasp of the lock in projected position.

Fig. 4 is a view similar to Fig. l showing the hasp of the lock in retracted position.

In the drawings the numeral 1t) designates a door of well known construction embodying a metallic panel 11 formed with horizontal corrugations 12. The door 10 which is shown fragmentarily is illustrated in closed position and secured by means of a lock embodying the instant invention. ln such position the door engages a front stop 13 which is riveted to a front door post 14 partially shown in the drawings. The door post 14 forms part of the side wall of a railway freight car which also embodies metallic sheathing 15 secured to the door post by the same rivets which fasten the front stop 13 thereto. In order to secure the door in closed position, a lock 16 embodying the instant invention is utilized. This lock embodies a hasp fastener 17 disposed upon the outside of one of the horizontal corrugations 12 and reinforced by a member 1S lying upon the inside of the corrugation. The hasp fastener and its reinforcement are secured to the corrugation by means of rivets 19. The hasp fastener 17 is formed with a gooseneck portion 20, the end 21 of which extends through the metallic panel 11 and the hasp fastener reinforcing member 1S as illustrated in Fig. 2 of the drawing.

' The lock lo embodies a hasp 22 which is formed with an eye 23 and a box section 24 through which a vertically disposed locking pin 25 is adapted to extend when the lock is in locking position. The eye 23 of the hasp is round and an eccentric disk 26 is seated therein. This disk is formed with a circumferential ilange 27 which overlaps the eye of the hasp and which may be welded ICC to kthe hasp if desired. Notches 28 are formed in J4the flange 27 of the disk so las to aid in rotating the disk relative to the eye of the hasp when this 'becomes necessary. The end 21 of the hasp fastener extends through the eccentric opening 29 formed in the disk -26 so as to swingably support the hasp.

The lock 16 further embodies a lock bracket 36 which is secured as by means of rivets 31 to the door post 14 of the car side. The lock bracket which is `preferably in the form of a casting embodies vertically spaced hous-

.ings

32 and 33 through which the pin 25 is ladapted to extend. When the hasp is in locking position the .pin

.also extends through the box-section 24 thereof so :aszt'o jprevent opening movement of the door.

kAs illustrated the .pin preferably is one which has a straight :side 314 adapted to bear .against the lock bracket and a tapered side .35 which is adapted to be uengaged by a similarly vtapered walli36 of the box section of the hasp.

T he lock bracket 3) carries opening and closing lever 37 which is pivotally supported in a vertical position at .the lower housing member 33. The lever 37 is formed lwith a lug .3S which is adapted to be received within a `recess 39 formed in the hasp fastener and to cooperate Vwith the walls of this recess in order to impart initial opening .and iinal closing movements to the door asis well known.

Fig. l illustrates the desired relationship between the .hasp and the pin when the door is locked and the corresponding position of the eccentric disk 26. In order "to -obtain .the illustrated relationship between the .hasp and .the pin prior to applicants invention a timeconsuming adjustment of the lock bracket or of the hasp 4fastener vor .hasp was frequently required. This is obviated by the `instant invention. If the illustrated position of the lock .bracket and the .pin is not obtained at the time that vthe lock bracket Aisapplied to the car side, it only becomes .necessary to lrotate the eccentric disk 26' within the eye of '.the .hasp in -ordertoproject or retract .thehasp as may be required .totestablishathe desired relationship between the hasp and the pin. Where the disk has been secured to the eye of the hasp fastener by a spot of Weld material, this weld is first broken away in order to permit the desired rotation of the eccentric disk.

Fig. 3 of the drawing illustrates the hasp in its extreme projected position. This may occur after the railway car has been placed in service as a result of the shifting of the hasp fastener or for other reasons which occurs when the car is subjected to impact. lt will be observed from Fig. 3 of the drawings that when such shifting occurs the pin 25 is permitted to fall to its lowermost position so that all `of the take-up which the shape of the pin normally permits is lost. When this has occurred the door can lash back and forth upon its supporting track so that wear in the parts of the lock will occur as is well known in the art.

in order to restore the take-up of the lock the eccentric disk 26 is rotated counterclockwise. Such rotation of the eccentric disk causes the hasp fastener to be retracted or moved toward the right as viewed in Fig. 3 of 'the drawings. rThis permits the pin to be raised so that the take-up which it provides is restored.

Fig. 4 of the drawing illustrates the position of the hasp and the relative position of the pin when the hasp has been retracted to its extreme position. To establish this relationship the eccentric disk 26 has been rotated counterclockwise from its position shown in Fig. 3 of the drawing to the position shown in Fig. 4. It will be understood, of course, that the degree of rotation of the eccentric disk will depend upon the extent to which the take-up provided by the tapered pin is to be restored.

While the invention has been illustrated and described in connection with a take-up lock, it will be apparent that it is applicable as well to locks which. employ straight pins.

It will be apparent that numerous changes and modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes `be comprehended within this invention which is to be limited only by the scope of the claims appended hereto.
