OF CHICAGO, ILLINOIS, A CORPOB CAR DOOR Application filed December 9, 1929. Serial No. 412,596.

This invention relates to a car door and more particularly to a door for stock cars and concerns itself with a door having one or more auxiliary doors for loading and unloading ay double deck stock car.

The invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and defined in the appended claims.

in the accompanying drawings which illustrate a preferred form of this invention and in which similar reference numerals refer to similar features in the different views.

Figure 1 is a fragmentary side elevational view of a stock car containing a door involving this invention.

Figure 2 is a view similar to Figure 1 but showing the door in open position and the auxiliary door in closed position.

Figure 3 is an enlarged fragmentary sectional view taken upon the lineIII-III of Figure 1 looking in the direction 0f the arrows.

Figure l is an enlarged fragmentary sectional view taken upon the line IV-IV of Figure 1 looking in the direction of the arrows.

Figure 5 is an enlarged fragmentary sectional view taken upon the line V-V of Figure 1 looking in the direction of the arrows.

Figure 6 is an enlarged sectional view taken upon the line Vl-VI of Figure 2.

Figure 7 is an enlarged sectional view taken upon the line VII-VII of Figure 1.

Figures S, 9 and 1() are enlarged fragmentary det-ail views illustrating modified forms of guides for the auxiliary door.

Figure 11 is a fragmentary sectional view taken upon the line XI-XI of Figure 12.

Figure 12 is an enlarged fragmentary elevational view of the latching means for the auxiliary door.

Figure 13 is a fragmentary side elevational view of a stock car illustrating a modified forni of the invention.

In the drawings there is shown a door 1 for a stock car and those parts of thestock car which are adjacent the door. The door comprises a metal frame consisting of a front Z bar 2 and a rear angle bar 2a, a top Z bar `being loaded.

the upper o, AssIGNon 'ro CAMEL ooiviiuiivr. yArion or iLLiivois 3. which has its web resting upon the top of the door and a guide flange 3a (Figure 3) extending inside of the depending flange of a track 4l, and a lower Z bar 5 which has a depending flange 5a members are suitably (Figure el). These frame connected together by gusset plates 6 to provide a rigid rectangular frame. The Z bars 3 and 5 are connected by an intermediate brace or strut 7.

Spaced horizontal slats 8 are bolted or secured to the lateral frame members 2, 2a and strut 7.

The door is supported upon means of rollers 9 ]ournalled in the track 4 by suitable hangers 10 secured to the upper portion of the door as is well known in the art. ln order to guide and maintain the lower edge of the door from swinging outwardly too far, a guide rod 11 is attached to the sill of the car and a closed link 12 secured to the depending flange 5a encircles said rod.

. The stock car shown is of the double deck type. The floor of the upper deck is indicated it is necessary and same from escaping while the lower deck is To this end, the main door 1 has been provided with an auxiliaryv door 14 (Figure 2) which moves relative to the main door so that it can be moved to act as a barrier for the upper escape of the lading.

vto the main door so that it can be slid across deck when the main door is open 'as shown in Figure l2.

For this purpose,

provided with open space 15 upper deck for the It will be noted that this open space is bounded at its upper and'lower limits by the transverse like guides 16 (Figure 5).

double channel It will be vnoted that each double channel guide has a channel 16a for receiving a Slat 8 of the door and a channel 161 for receiving an edge of the auX- iliary door. and form a Instead of the double modifications shown in The channels 1Gb face each other slideway for the auxiliary door.

A plate 17 is attached to the strip 8 in opposed *,relation to the last mentioned'liange of the Z bar 19 to'forin a channel like guider-Cay for .receiving the edge of the auxiliary door,

y The auxiliary sliding door 14.-Y corsista Yi a rear U shaped metal frame member 2U and a pair of front plates Q1 (Figure lVooden slats 22 connect the rear frame n'ieinber Q0 and the plates 21 which extend in parallei rela-v tion. The outer plate 31 is outwardly oii'set to increase the distance therebetween for ceiving the slats. The upper and lower slats 22 are preferably hevelled or tapered as shown in Figure 5 to facilitate the sliding movements of the auxiliary door. The inturned flange of the front Z bar 2 upon the main door is cut away the auxiliary door as indicated at i3 (Figure 6) to allow the auxiliary door to pass. However when the auxiliary door has been projected shown in Figure 2the rear end will be behind the front Z bar 2 as shown in Figure 6 and will be restrained from outward movement, while .the front end will be latched to the front door post 24 in a manner that will now be set forth.

Between the forward ends of the plates Q1, Y there is a latch hook 25 which is provided with a slot Q6 through which a pivot 27 passes. The pivot is in the form of a rivet that passes through the plates 2l. This lat-ch hook 95 is :designed to extend through a slot Q8 in the front door post and come into latching engagement with the bottom of such slot so that the auxiliary door will he held against. sliding movement and also against outward iovement at its front end so the main door can be opened while the auxiliary door remains latched or anchored to the front post. Vhile only one .latch hook has been illusftrated it will he understood that several may Y be used if desirable. The latch hook 25 may be readily swung upwardly and out of engagement with the slot Q8 and into the position shown vin Figure 1Q in .yhiclrposition thev latch has dropped down bringing the upper end of the slot into engagement with :the pivot so that the latch hook may be moved through a smaller arc when swung to its operative position through the slot 28, and

may be extended at the same time due to the slot 26.

In order to latch the main door in its closed position, a hinge support 29 is attached to each door post as shown in Figure 7 andalatch member 30 is hinged to each support. 29 so as to be swung over the outer surface of the door. Eachlatch member is provided with a slot 31. for receiving hasps upon the door. Each latch member also has an integral hasp 32H; A chain 33 is anchored to the door above each pair of hasps 32 and 32d and the lower end of each chain carries a fork 3i for extending through the hasps. The outstanding flange of the front Z bar 2 is cut away as indicated at 35 in Figure 7 to allow the. front latch member to swing flat against the door.

ln Figure 13, a modified stock car door 1n is shown. The parts of this modified door are substantially the saine as the preferred form and princiiiially differs therefrom in the use of two auxiliary doors 14, one for the upper deck and one for the lower deck.

lt will be apparent that it becomes a simple mattei' to load double deck car according to this invention, especially when it is loaded with live stock. According` to this inve ition the main door is opened and the upper deck is loaded, then the auxiliary door is moved over the upper deck and latched to act as a barrier. The lower deck may then be loaded and thereafter the main door may be slid to closed position and latched as previously set forth. Then two auxiliary doors are usedas shown in Figure 13, either the upper or lower deck may be iirst loaded as is readily apparent.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:
