' Application flied November 1o, 1924. serial No. 748,873.

To ZZ'ww/m, t may concern:

Be it known that I, KARL a subject of Great Britain, residing at Chicago, in the countyof Cook and Statey of `for the locking bolt; to serve as a means' of assembly of the locking bolt with the post; and to permit the locking bolt to be held in assembly with its housing, by the presence of the post in the' shoe; the general construction and design ot the parts being suchithat they may be produced by the relatively cheap process vof casting and with a minimum of expense for iinishing.

In carrying'out the invention. a cast metal shoe having a plurality ot' sides, preferably four, for positioning the end of the post within it, and with the face: orl foot by ywhich it rests against the floor or other portion of the freight car structure togwhich 'the post is yto be secured, is also provided with a vsocket in whicha bolt can slide longitudinally into andv out of a keeper in the car body; said socket-being provided in its outer wall with a' slot that receives a stop pin projecting transverselyl from the bolt, and having its rear side, except at the bottom where the bolt is closely confined by a hole in the bottom plate of the shoe, originally open and depending upon a face oi the inserted post as a closure therefor; the

bolt being provided, on its rear side withy a spacing lug or projection that bears against the face of the post to keep the bolt in normal relation to the socket in which itl slides; and the design being such that the bolt can be assembled with its socket by iirst entering its locking end in the hole of the base plate then swinging the bolt laterally into its socket with its stop pin in position to enter the slot in the front wall ot' the socket.

In the accompanying drawing,

Figures l and 2 are two elevational views at right angles to each other of the com- F. NYSTROM,l

kwhichis introduced into the shoe, aiter the bined shoe and 'boltsocket, with the bolt the socket, Figures 3 and 4 are, respectively, a bot Vtonrplan anda top plan view of the same, and` e Figure 5 is a perspective view of the locking bolt.

l represents a cast metal shoe or housing designed lto receive the end of Va post 2in order to adapt the post for use as a mov able door post of an auxiliary freight car door. Shoe l embodies in its construction 4a front wall 3, a rear wall 4 and side walls 5 and 6. Formed integrally with the `front wall 3 is a socket 7 vin which is mounted for longitudinal sliding movement, a locking' bolt 8. The outer wall of the socket 7 is formed with a slot 9 that receives a l stop pin 10 v formed integrally with'or otherf Eintroduced in its socket l7 from the inside of they shoe, the presence of the lost 2,

bolt isf'in place, ybeing relied upon to con- ,fine the -bolt against displacement. To keep the bolt 8 invertical position, 'it carries a rearwardly extending lug ll which contacts with the vfaceand is opposed .to the line across the open end of the socket. Shoe -1 is 'closed at the bottom by a stop l2 formed with a bearing lfoot 13, through which it rests upon the sill or other part of the outer part ol the car. The socket 7 has l a bottom opening 14 through which the bolt 8 may extend, -in entering a keeper with which said portion ofthe carv is provided. As shown by dotted lines in Figure l and surfaceshading in Figure 4, the'bottom or stop l2 of the shoe l merges through means of beveled or curved surface 15, with the socket 7 in korder to facilitate entry of the bolt into its socket at an angular position that will permit the stop pin l0 to enter the slot 9 before the bolt assumes vertical position. Extending laterally from the upper portion ol the slot 9 is a recess 1G that receives the stop pin 10 when the bolt is withdrawn and this recess -is formed at the bottom with a seat 17 in which the stop pin may drop behind the horn 18 that confines the stop pin against accidental displacement. The horn 18 has its salient not outer face of the socket 7, but beveled or inclined from the outer face inwardly and downwardly so as to prevent lodgment of the stop pin l0 upon the horn in case of accidental rebounding of the bolt as a result of shock, jolt or other interference nvhen in service. The upper end of the slot 9 is defined by an inclined Wall 9a, which automatically directs the stop pin 10 laterally to, a position over the notched seat 17 by the mere act of throwingf the bolt upward, so that when released the pin l0 will drop` into said` seat and be conlined there against return to locking' position by means of the horn 1S.

l claim:

i.' combined post shoe and boit. sfmli'et for door pests coinprisingv a housing adapted to r iceire the endof a post, and a bolt socketintegral therewith, adapted to receive a bolt 'for locking the shoe 'with its contained post, in po; tion relatively to `a structure in which the post is used; said socket having its inn-r side open to the post to admit the bolt laterally thereto andsaid housing supporting the post with the face thereof in position to close the rear side of the socket.

The combination of a shoe` adaptedv to receive andv confine the end of a post or stud, a bolt socket integral therewith, having its side adjacent the shoe open. to the interior thereof but adapted to be closed by the face of a post when in place inftheshoe, and a bolt in said socket having av spacingy lug presented,towardthe open side oi' thesocket and adaptedto contact Withithe post to limit the tipping of thebolt inthe socket.

3. The combination of ashoeconstructed to receive and eonine the end o avpost or stud, a bolt socket integral therewith and havingits side toward the shoe open to the shoe but adapted to be closedby the fare of a post inthe shoe, and having` astop. pin slot in its outer Wall, and: a bolty adapted to be introduced laterally into the socket, from the slice, betere the post is inplace, and havinr a stop pin adapted to said slot; the slot g located to receive the 4stop r pinwith the lateral movement of the bolt intoA its socket. el. he combination of a shoe adapted to receive and confine the end ot a postor stud,

and a foot which supports said bottom in elevated position, a socket integral Wit-h said shoe, open on its innerV side to the interior oit the shoe, and a locking bolt adapted to enter the socket of the shoe, by an endivise movement which introduces the end` of the bolt.. intothe lower portion oli the socket-,folloiredl by the lateral movementwhich completes theintroduction of the bolt.l

G. The combination of a shoe adaptedto receive and coniine a postor stud, having a bottom which provides al Step for the post and a foot which supports said bottomfin elevated position, a socket integraliwith said shoe, open on its inner siderto theinterior of the shoe, and a locking bolt; adapted to enter'thesoclret of theshoe, by an end'ivise movement which introduces the end of the boltI into the lower portionof the socket, followed by the lateral movement which coinpletes the introduction of the bolt; the stepping bottom of the shoe beingv merged with the` bottom of. thesocket through means of a beveled, surface. V i

7. The. combinationorfa bolt andA ashoe adapted to receive and, confine the end, ofa postor. stud, and a bolt socketl carried/by said shoe, formedi with a` slotA in, its outer Wallto receive a stop pinlby Whichlthe bolt is to be controllech-and havin@ a recess openingflaterally fromsaidslot which recessprovides .vapseat for said stoppin; the upper Wall oli the slot comprising a detiectingsuriace which directs theupwardly movingstop pin laterally to a position from Whichit gravitates into said seat when released.
