Application led .Tuly 23,

4The p-resent invention relates to side door constructions.

More particularly the present invention relates to the doors of railway house cars of the type commonly called automobile cars. House cars for the shipment of automobiles or other bulky lading require a particularly wide door opening. Cars of this sort are commonly provided, in addition to the usual sliding door, with a secondary or supplementary door, which second or supplementary door is slidably movable to provide a door opening of extraordinary width, but which may be stationarily held when a door opening of such extraordinary width is not required. In order to lock said supplementary door in its closed position, it is common to provide a movable door jamb which may be secured tov said supplementary door or may move independently of said supplementary door. In either case said jamb should be capable of movement longitudinally; of the car and should have means for locking same in position. Certain types of door jamb for said supplementary doors have provided means lfor holding a'nailing strip for theY securing of grain doors such as are used inlining the car when the car is used for the purpose of' carrying grain or other finely divided lading. It is common to provide the amb of the supplementar door with latchin members for latching t e jamb in door closmg position.

An object of the present invention is to provide a construction involving a supplementarA door and a door amb therefor, which ]amb requires a minimum of kinds of fittings.

A further object is to provide a door jamb involving relatively simple parts which include castings at the top andbottom of said j amb, which castings may be identical, theren by simplifying the matter of stocking repair parts.

V A further object is to provide a door `jamb having socket members at its top and bottom, which socket members provide housings for latchin'g members and which house the two extremities of a wood filler post.

A further object is to provide a door amb of great strength, which will afford protection to the means lfor operating the latches above referred to.

A further object is to provide a socket member which may be used either at the top 1927. erm No. 207,877. i

post arrangement The numeral 10 indicates the side sill and the numeral 11 indicates the side plate of a railway box car. The numeral 12 indicates init-s entirety a movable door jamb which in the construction illustrated is la metal jamb. Said jamb is secured to the supplementary door 13. VSaid jamb is adapted to be moved with a movement of translation longitudinalof the car along with said supplementary.

l diner 13. Figure 1 illustrates the jamb 12 in its home or door closing position. In this polsition certain latching mechanism cooperf atively associated with the jamb 12 engages with detent members stationarily mounted upon the side sill and side plate of the cal.

, over a plain angle and bers 14 and 15 is provided With overhanging shoulders 17 on the'tvvo sides thereof, which cooperate With extending portions to be ref terred to hereinafter, rigidly secured tothe j amb 12, whereby when said j amb 12 is in its home or door closing position, said jamb' acts as a tie member to prevent spreading between the side sill 10 and the side plate 11. 'lhe detent 14 is provided on its upper surface with the recess 13 providing a square shoulder i 19, and the detent member 15 is provided with the recess 2O providing the square shoulder 21, which shoulders 19 and 21 operate with latching members,to be referred to hereinu alter, to hold the jamb-12 in its home or door closing position. y

The jamb 12 preferably is embodied in a rolled shape 22, the cross section ot which is illustrated in Figure 3. lt will be noted that the rolled shape 22 is a F-bar, the Web 23 oi' which is disposed transversely of the car 'and the flange 24` oit Which is disposed longitudi nally oit the car. The other lane 25 may take the form of a reinforcing bul y25. rlhe Z-bar 22 has an improved section modulus l thereby permits the use of a relatively light Weight shape, which relatively light shape has the advantages thatv fabrication and handling'. are simplified. its will be pointed out hereinafter, the flange or bulb 25 has the further advantage that. it protects the operating bar ot the latching mechanism ont `the car from damage due to shifting lading. rl`he extremity of the flange 24 of the rolled shape 22'is inwardly bent to provide a lip 26, which providesv a door guide tor the main door' 2K7.

Disposed within the reentrant angle ot the rolled shape 22 is the Wood filler post 23, 'which filler post is adaptd to have a nailin strip 28A secured thereto.l `\\lt Will be noted that the rolled shape`22 presents a reentrant angle toward the interior ot the car and toward the opening controlledby the main door 27 V(see Figure 8), this construction having the advantage that the filler post 28 and nailing strip 23A may be chamtered oil', as indicated in Figure 3 by the-line 28B, to provide a maximum of space to permit the clearance of hubs and tenders of automobiles inserted diagonally into the house car.

Disposed at the top and bottom ot the jamb 12 are the housings or socket nimnbers 29-29, which are identical and in a preferred Leefbaar embodiment of the present invention take the form of castings. The Wood filler post 23 is gained into said castings 29-29 at the two ends ot' said strip 28. Figures 4, 6, 7 and 9 show one of the castings 29 in the position it assumes when used at the bottom ot' the jamb 12. lt Will be noted` that said casting 29 includes a socket portion 3 0 in -Which the filler post 28 is disposed, said liller post 28 having a reduced end lportion 31 tor this purpose. @ne Wall 32 of the casting 29 is provided With a. pair of holes 33-33 t'or the reception of rivets or bolts tor securing said Wall 32 to the web ot the rolled shape 22. Each ot the Walls 34-34 adjacent to the Wall 32 is provided with the hole 35. ln the case of a casting 29' used at the bottom ot the jamb 12, one of said holes 35 is used tor receiving a rivet or bolt Jfor securing the corresponding vfall tothe flange 24 ot the Z-bar 22. 1n the case ot a casting used at the top of the jamb 12, the other of said holes 35 is used 'for securing the corresponding Wall 34 to the iian'ge 24 oi thel Z-bar 22.

llrom an inspection ot' Figures 2, 3, 4, 5, 6 and 7 it will be noted that the extremity of the casting 29 spaced. from the Walls 32 or 34-34 is provided With the pair of lip portions 36, which extend toward one another .and are adapted to -have overlapping relationship with the shoulders 17-12 ot' the detent members 14 and. 15 at the bottom and top ol the car.

-lteterring to the sectional view illustrated in Figure 7, the inner conformation ot each sidewall 34 is illustrated. rllhe two side Walls 34 are identical, -so that a description of one of said side Walls will sutiles-for both. lt Will be noted that the inner surface of each wall 34 is provided With projections forming a pair of sockets 37 and 38, which sockets providebcaring's for latching members 39 and 40 disposed, respectively, at the bottom and top ot the jamb 12. l lt Will be noted that the- socket portions 37 and 38 have restricted entrances 41 and 42, respectively. yl`he trunnions 43 and 44 oi the latch members 39 and 40, respectively, are provided With fiat faces, whereby said trunnions 43 and 44 may be admitted through ,said entrances 4.1 and 42, respectively, when the latches are turned at predetermined angles. The flat laces of the trunnions 43 are indicated by the numerals Ll-5--45- A dat tace on the trunnion 44 is indicated by the numeral 46;, Said flat faces 4.5-45 and 4G are so disposed upon thc trunnions 43 and 44, respectively, that said trunnions'can be removed 'from their corresponding socket portions 3T and 33 only when the latches 39 and fi-(l are disposed in an angular position which they cannot assume u'ith the door janib and the letents 14 and 15 in normal positions within the car and with the liller post 23 in position.

rlhc latches 39 and 40 lare connected to one lSO another by means of the latch operating bar 47. The details of the bar 47 need not bedescribed here/in, the subject matter of a similar latch operating bar being described and claimed in the Tobin and Darrow Patent No. 1,533,621, issued April 14, 1925. It will be sulicient to state that the bar 47 causes the latching members 39 and 40 to move in unison, whereby the jamb 12 will either be in latched conditon at both top and bottom, or in unlatched condition at both top and bottom,

'litii particular reference to steel door construction, attention is directed to the reinforcing'plate 48 secured along one edge to the door 13 by means of a row of rivets 49 and along its other edge to the web of the Z-bar 22 by means of a row of rivets 50. Said rein- Jforcing plate 48 not only strengthens the construction, but prevents lading from getting into the'corner between the door 13 and the web of the Z-bar 22. The front edge of they .door 13 and the flange 24 are secured togethel by means of the row of rivets 5l. y The rolled shape 22, the reinforcing plate 48 'and the front edge portion of the door 13 thereby form a trusswork which effectually protects the door jamb against twisting. The filler post 28 is secured to the rolled shape 22 by means of bolts 52 and 53.

Though the tiller post 2 8 maybe a permanent part of the j amb, it may be desired to remove said iller-post in case said filler post becomes injured and to insert a new filler post. In order to remove said filler post 28 without requiring the dismantling of thc castings 29-29 from the Z-bar22, or removing the j amb proper from the door to which it is riveted, the filler post 28 may be cut transversely, as indicated by the numeral 49. After removal of the holding bolts, the two eX- tremities of the liller post 28 maybe readily removed and other sections may be mounted in place, the bolts being reinserted to secure the two sections of said filler post in rigid relationship with the Z-bar 22.

As appears from the drawings, each housing or socket member 29 is open from top to'` bottom, this construction having the decided advantage that in case it should be necessary to remove the latch 39 at the bottom of the jainb and replace same with another,f"the change can be made veryvreadily without taking the car out of service. Though the latches are ordinarily quite sturdy, breakage ot the lower latch may occur if said latch is subjected to very roughv treatment. To

change a lower latch 39, the filler post may' be removed in a manner referred to above, and the jamb may be moved to a position free of the detent'l4, 'such for example as the positon illustrated in' Figure 9.
