Claims. 1

This invention lrelates to door locking and closing devices. This invention has for an object the association of locking and closing devices for sliding car doors whereby to secure a reduction in the number of parts together with a decrease in weight and cost and a reduction in the eX- pense of application.

A further object is to provide a door locking and closing device which permits disposition of a closing lever so that it is more easily operable.

A further object is to provide a door locking and closing device for sliding car doors embodying a lock bracket and a tapered locking pin and means carried by the lock bracket for limiting upward movement of the pin.

A further object is to provide a door locking and closing device embodying a hasp and a lock bracket wherein the hasp is constructed to cooperate with locking means carried by the bracket to lock the door and with a horizontally positioned lever also carried by the bracket to impart closing movement to the door.

Other objects of the invention will become clear as the description thereof proceeds.

In the drawings forming part of this specification:

Fig. 1 is a fragmentary elevation showing a device embodying the instant invention applied to a railway box car, the device being illustrated in door locking position.

Fig. 2 is a View similar to Fig. 1, showing the door partly open and parts of the device engaged to impart closing movement to the door.

Fig. 3 is a horizontal section taken on line 3 3/ of Fig. 1 looking in the direction of the arrows. Fig. 4 is a horizontal section taken on line 4--4 of Fig. 1 looking in the direction of the arrows.

Fig. 5 is a vertical section taken on line 5-5 of Fig. 1 looking in the direction of the arrows.

Fig. 6 is a Vertical section taken on line 6 6 of Fig. 1 looking in the direction of the arrows.

Referring to the drawings which illustrate a preferred embodiment of the invention, numeral ID designates a portion oi the side wall of a railway box car which is provided with a door opening II defined by means of door posts, one of which is partially shown at I2. The side wall Ill also embodies metallic sheathing I3 secured to the door post I2, as illustrated in Fig. 3 ofthe drawings. A front stop I4 is also secured to the door post I2.

The door opening II is adapted to be closed by means of a sliding door I5 which may be of any desired construction but which, as best illustrated in Figs. 1 to 3, inclusive, of the drawings, embodies a metallic panel I6 formed with a plurality of horizontal corrugations Il'. Adjacent each vertical margin of the door the metallic panel is oiTset outwardly, as indicated at I8, to provide a flange I9 substantially parallel to the main plane of the panel. The vertical margins of the door are reinforced and, as best illustrated in Fig. 3 of the drawings, the reinforcement for the front vertical margin of the door is obtained by means of a substantially Z-shaped reinforcing member 2l) which overlaps the flange I9 of the metallic panel and is secured thereto in any desired manner. The reinforcement for this margin of the door is completed by means of a backing plate ZI which is secured to the panel I6 inwardly of the offset portion I8 as by means of rivets 22 and to the reinforcing member 2l! as by means of rivets 23. The front stop I4 is adapted to limit closing movement of the door by engagement to the vertical reinforcing member 2U.

The door is adapted to be locked in its closed position by means of a locking and closing device embodying the instant inventio-n. This device embodies a hasp fastener 24 preferably disposed upon and secured to one of the horizontal corrugations Il as by means of rivets 25. The hasp fastener is reinforced by means of a reinforcing member 26 lying within the horizontal corrugation II and secured thereto by means of the rivets 25. The hasp fastener 24 extends through an eye 21 formed in a hasp or locking member 28 so as to swingably support the hasp. The hasp is provided with a box section 29, as best illustrated in Fig. 3 of the drawings, through which a tapered pin or locking element SI'I is adapted to extend in order to lock the door.

The pin 3D is carried by a lock bracket 3l secured to the car side adjacent to the door opening II as by means of rivets 32. The lock bracket 3l, which preferably is in the form of a casting, is formed with vertically spaced housing members 33 and 34 which slidably receive the tapered pin 30. In locking position, as more clearly shown in Fig. 1 of the drawings, the straight edge 35 of the tapered pin 30 bears against the sides of the housing mem- bers 33 and 34 and the inclined edge 36 of the tapered pin assumes locking engagement with a correspondingly tapered wall 31 of the box section of the hasp.

As best shown in Figs. 1 and 2 of the drawings, the upper portion of the tapered pin 39 is reduced in width so as to provide a shoulder 38 extending inwardly from the tapered edge 36 of the pin. The upper housing member 33 is formed with spaced ears 39 and 40 between which avcatch 4I is swingably securedV as by means of a rivet 42.

The swinging catch 4l lies in the plane of the tapered pin 30 and comprises a nose portion 43 adapted to lie vertically above the shoulder 38 of the pin when the latter is in locking position and a nger grip portion 44 provided with an opening A1&5 by means of which the catch can be operated. The nger grip portion over-balances the nose 43 so as to bias the latter into overlapping relationship with the shoulder v38 on the tapered pin.

As appears from Fig. l of the drawings, overlapping relationship between the-shoulder 38A and the nose 43 of the swinging catch is provided for as soon as the tapered pin'rextends -suiciently below the lower housing member'34 to permit -a seal (not shown) to be threaded through alined seal receiving openings 46 and-41 formed respectively in the lower portion of the pin and in the lock bracket. It is apparent that the swinging catch will prevent the pin from moving upwardly to such an extent that the seal may be sheared. However, in the event that the pin is -in theV position described immediately Vabove yand the vdoor is not fully closed, it 'is -possible for the .door t0 move in closing directioniand the tapered pin to drop by the actionof gravityto take iup the clear- 'ance created by the closing movementofthe vdoor --while preventing return opening'movemen't of the door. "The dropping ofthepin is 'not 'interfered with 'by the swinging catchlll which -is inposition to effectively prevent accidental upwardly 'movement of the pin to =an extent 'which might 'result in shearing of theseal. It will beiclear, nmoreover, from the showingV of Figs. 1 and 2 of the drawings that irrespective-of the position of the ypin when-it is out'of locking engagement with the hasp, the pin can, without 'interference from the swinging catch, be dropped-throughfthe housing members and automatically assume the relationship with the catch as illustrated in Fig. l of the drawingsso that manual manipulation of 'the catch is unnecessary.

In addition to the foregoing function Aof the -illustrated device of the instant invention,- it serves aswell to impart closing move-ment of the door.

For this purpose the hasp`28 is provided-with an extension i3 reinforcedby means ofa ribi. The extension is formed witha plurality of shoulders 50 which extend downwardly so'asto be capable of selective' engagementby'an upstanding lobe l formed on a' horizontally kposition-ed'lever 52.

rIhe 1ever52 is swingablysupported 'between a pair of ears 53 and'll extending from the lower housing member '3d' of the lock bracket. rr.Ehe

swingable support is obtained by means .ofa rivet Vis in partially open position, as forlexaniplethe position illustrated in Fig. 2 of the drawingathe hasp 28 is disposed so thatv itis supportedr upon the lower housing member-34. The Yleverf52 is thenswung in clockwise Y direction .until engagement between the-upstanding lobe 5l on the -lever and one of the shoulderso on the hasp is obtained. The lever 52-is-then Yeasily .swung in counter-clockwise direction since it is pulled downwardlyandduring this movement ofthe le- Zontai.

ver the door is moved in closing direction. f at this time the door is not fully closed, the operation described above is repeated by engaging the opstanding lobe 5| with another of the shoulders 50 and this process is continued until the door is closed. When this has occurred, the pin is dropped through the lower housing member and sealed. As soon as the shoulder 38 on the pin passes below the nose 43 Yof the pivoted catch 4l, the latter automatically swings in counter-clockwise direction so as to position the nose 43 vertically above rtheV shoulder 38 and thereby prevent accidental upward movement of the pin and possible shearing of the seal.

During the operation of the lever to effect closing movement of the door engagement of the lever with the shoulders 50 on the hasp is insured by the reinforcing rib 49 which prevents the hasp from swinging outwardly.

As shown in Fig. 1 of the drawings pin 3] is in the uppermost door locking position whichfwill permit sealing of the' doorand 1ever52 is hori- If because of normal discrepancies Vof car'construction as, for example, `a door opening which is too wide, or a door `which is too narrow, the door is not fully closed Awhen the pin,-hasp and lever are in the position shown inrFig. A1,1th'e door may move in closing direction. Upon such movement, the pin will drop and re-estab'lishfengagement with the hasp as is well known. This action can continue until reinforcing member 2B is in contact with front stop i4.

At the beginning of this movement of the` door, the lever 52 is horizontal and inengagement with the innermostshoulder 5B. AIt is'clear.' however, from the construction of the hasp and its relationship with the `v lever`that the lever when in horizontal position will not impede themove'ment of the hasp with the door. Similarly, if the lever `should not be 'in horizontal position when the door is locked and sealed, closinglmovement of the door can occurfwithout hindrance fromthe lever.

It will be* apparent that numerousohanges and modiiications in the details of the invention-will be clear to those skilled in the art. It is intended, therefore, that all such modiiications and changes be comprehended within this instant invention, which is to be limited only bythe scope of the claims appended hereto.
