REFRIGERATOR-CAR.

Specification of Letters Patent.

Application filed January 17, 1912. Serial No. 671,614.

to form the inner wall of the ice container- .in connectlon wlth improved means for holding the bulkhead in cooperative relation with the walls of the car.

To this end the invention consists in the features of construction, combination, and

arrangements of parts hereinafter described and claimed. I

In the accompanying drawings forming part of this, specification, Figure 1 is a cross section of the car showing the bulkhead in elevation; Fig. 2 is a section on line :a-w of Fig. 1; Fig. 3 is a vertical longitudinal section of one end of -the*car, broken away, showing my improved bulkhead in partly raised positionyFig. 4 is a section online yg of Fig. 3; Fig. 5 is a lon itudinal section through a portion of the bulkhead and cooperating guide way formed in the side wall of the car; Fig. 6 is a section on line 42-2 of"Fig. '5; Fig. 7 is a. perspective view of the bulkhead broken away. Fig. 8 is a perspective view broken away of a portion of the top of the bulkhead frame; and Fig-9 isa perspective view broken away of a portion of the bottom of the bulkhead frame illustrating the method of assembling the members of the bulkhead.

In the drawing 2 represents the floor, 3 the end wall, 4 the side walls, and 5 the roof of an ordinary refrigerator car. tending across the end of the car and adapted to form the inner wall of the ice container is my improved bulkhead A. The bulkhead is of knockdown metal construc tion as shown particularly in Figs. 5 to 9.

brackets 10 which are overlapped by the lower ends of the uprights, the uprightsf being secured to the brackets as by boltsll,

formed with a depressed corner portion 12 Patented May 20,1913.

to receive the inwardly bent front edge of v the upright 8. The upper end of the upright is secured within the adjacent end of thetop cross bar 6' as by an angle bracket -13. The intermediate upright-s 9 are secured'to the bottom crossbar 7 by means of a bracket 14. The bracket 14 is formed with a central opening 15 to receive the lower ends of a pair of uprights 9 placed back toback, the flanged edges of the u rights 9 extendinginto recesses 16 int c outside of the bracket so as" to stand between the bracket and upwardly extending front wallof the bottom cross beam. The

upper ends of the uprights 9 are secured in substantially similar brackets 17, the uprights being secured in said

brackets

14 and 17 as by means of the bolts 18 and the brackets being similarly secured to the upper. and lower cross beams. The end upright 8 and the opposed upright 9, with each additional pair of uprights 9, constitute receiving sides for the port frame sections illustrated specifically in Fig. 9. .Each port frame section consists of inwardly flanged metal side bars 19 between whichare supported a plur'ality of superimposed interspaced port walls 20. The port walls 20 may be secured .in the side bars 19 as by being formed at their ends with tongues 21 clenched throu h corresponding slots in the adjacent 'si e bars.

In order to support the bulkheads in guideways extending upwardly and horizontally in the side walls of the car, I provide the pivot bolts 23 and 2 1. The pivotbolt-s 23 are sli'dably supported at the upper corners of the bulkhead by sockets 25 carried by the end brackets 17 and into which sockets the pivot bolts slidably extend, the bolts being pressed outward by the springs 26 inclosed within the sockets. The outer ends of the bolts extend through openings in the end uprights of the bulkhead and ro-- ject into the guideways 22. Supporteo in the bulkhead below the bolts are the bolts 24, the inner ends of which bolts 24 slide in sockets 27 su ported upon .the inner faces of the ad acent uprights 9, said bolts 24 being pressed outwardly by the springs 28 inclosed within said sockets, the outer ends of the bolts extending through the end uprights of the bulkhead and projecting into the guideways 22. The

sockets

25 and 27 as shown in Fig. 6 are split, the socket members being connected by bolts 29, thus permitting the removal of the bolts.

In carrying the-bulkhead to supported position it will first be lifted out of the groove 30 in the car floor and as'soon as the pivot bolts 23 reach the horizontal portion of the guideways 22 the bulkhead may be swung outwardly, the upper'pivot bolts traveling ,rea'rwardly in the horizontal portions of the guideways and the pivot bolts 24 traveling upwardly in the vertical portions of the guideways, allowing the bulkhead to be carried to raised position underneath the roof of the car.-

I claim nothing inthe method of supporting the bulkhead in'the side walls of the eat, my present invention being limited to the construction of the bulkhead and associated parts.

In building the bulkhead in the manner shown I secure a bulkhead which may be made entirely of metal and in which the uprights are thoroughly braced and supported in connection with the top and bottom cross beams, and in which a plurality of port sections, as' shown in Fig. 9 are independently supported so that one port section may be removed and repaired without injuring the other portsections. I also secure aconstruction in which the pivot bolts are firmly supported and braced and at the same time easy of removal.

I claim as my invention:

1. In combination wit-h a refrigerator car,

' a transverse metal bulkhead supported therein and spaced from the adjacent end of the car, said bulkhead comprising top and bottom cross bars angular in cross section, a plurality of uprights secured at their ends within said cross bars and spaced to form frame openings, and ported frame sections consisting of uprights and connecting port walls supported within said frame openings.

2. In combination with a refrigerator car, a transverse metal bulkhead supported therein and spaced from one end of the car, said bulkhead comprising top and bottom .cross bars angular in cross section, a plurality of spaced uprights secured at their ends within said top and bottom cross bars, said spaced uprights being angular in cross section whereby said cross bars and uprights constitute inwardly channeled frame openings, and ported frame sections secured within the channels of said frame openings.

3. In combination with a refrigerator car, a transverse metal bulkhead supported therein and spaced from one end of the car, said bulkhead comprising top and bottom cross bars and connecting spaced uprights, said cross bars and uprights being channeled upon their inner faces and forming frame openings, horizontally ported frame sections fitted within the channels a of said frame openings, and corner brackets securing said frame sections and cross bars.

In testimony whereof I ailix my signature in presence of two witnesses.
