To all whom tin [6 7]: concern:

Be it known that I JOHN S. CAMERON, a

citizen of the United States, residing at.

Elliott, in the county of Ford and State of Illinois, have invented a new and usefulv door whichmay bereadilyand easily swungv v to a position exteriorly of the car and supported in such position to permit the car" to be used: for carrying'materialother thangrain.

Another object of the-invention is to provide a door of this character including a plurality of hinged sections which may be.

moved to their activeor inactive positions at the will of the operator to facilitate the loading and unloading of the car.-

A still further object of the invention is to provide means for adjusting the door vertically to eliminate any possibility of the door dragging on the floor of the car while it is being transferred from a position interiorly of the car to the exterior thereof, or vice versa.

W'ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a side elevational view illustrating a grain car door constructed in accordance with the invention as closing the door opening of the car.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3 is a sectional view taken on line 3 of Figure 1.

Figure 4 is a sectional view taken on line l4 of Figure 1.

Figure 5 is a sectional view taken on line 5-5 of Figure 1.

Figure 6 is a sectional View taken on line 66 of Figure 1.

Referring to the drawings in detail, the reference character 5 indicates a car Which GRAIN noon.

Application filed. January 6, 1925. -Seria1 No. 862.

is provided with the usual opening 6 normally closed by means of thesl-iding closure 7 provided with brackets- 8 which support suitable rollers that move along the track 9. Suitable cleats indicated at 10 are prof. -v1ded for holding thcshdm-g closure 7 to its proper position. i

The grain door wh ch forms the essence of the lnvention is indicated generally by the reference character 10, andincludes a plurality of-hingedly connected sections 11, which sections are supplied witlrlocking members 12 that are adapted to swing within; suitablekeepers to lock the sections 11 in;,their active positions.

' ,The lowermost section o fthe grain door is supplied With anop'ening that is normally closed by; .the hinged closure 13, sliding bolts 14 being provided and adapted to engage within keepers positioned in the'fioor of the car to hold the hinged closure 13 in its closed position.

Secured to the grain car door are supporting chains 15 that carry brackets 16 at their upper ends, which brackets have rollers 17 that move within the tubular track section 18, the tubular track section 18 being formed with a longitudinal slot to allowtho rollers to fit within the track section.

This tubular track section 18 is pivotally supported at 19, one end thereof being positioned within the slot 20 of the support 21 so that when the weight of the grain door exerts a pressure on the'outer or free end of the track section 18, the rear end of the track section 18 will be held against movement by its contact with the walls of the slot of the securing member.

In order that the tubular track section 18 will be held in a position to permit the grain door to be transferred from the track section 18, a latch member 22 is provided and disposed adjacent to the outer end of the slot 20 so that as the track section 18 is swung on its pivot, the track section will fall behind the latch member 22 to hold the track section against movement.

Mounted exteriorly of the car is a track section 24 which is formed with a beveled end 25 adapted to be engaged by the beveled end 26 of the track section 18 so that when the track section 18 is moved to a position as indicated in dotted lines in Figure 6 of the drawings, the beveled ends 25 and 26 will contact to provide a continuous track section and permit the grain door to be moved onto the track section 24- and to a position exterior-1y of the car.

In order that the chains 15 may act to hold the sections 11 ofthe grain car door in a vertical position, hasps 27 are carried by one of the sections 11 and are adapted to pass over the keepers 28, which keepers aecommodate the hook members 29 for securing the hasps against movement. These hasps 27 are provided With offset portions providing clearances for the chains,

From the foregoing it will be obvious that due to this construction, the grain car door may be readily and easily moved to its ac tive position, or moved out of its active position, adapting the car for use in transporting various types of articles.

I claim:

1. In a freight car door, a body portion,

a door opening, a stationary track section mounted exteriorly of the door opening, a

track section pivotally mounted Within the body portion and adapted to move into engagement With the first mentioned track section to form a continuation thereof, a support extending inwardly from the Wall of the car and having a slot, one end of the pivoted track section adapted to move in the slot, a spring member disposed adjacent to the slot and adapted to engage the pivoted track section to lock the pivoted track sex:- tion against movement, and a movable door section supported on the pivoted track section.

2. In a freight car door, a body portion having a door opening, a stationary track section supported exteriorly of the body portion, a track section pivot-ally mounted Within the body portion, a support extending inwardly and arranged near the door opening, said support having a slot, one end 01 the track section adapted to move in the slot, means disposed adjacent to one end of the support and adapted to engage the pivoted track section to hold the pivoted track section against movement, and a sliding door carried by the track section.

In testimony that I claim the foregoing as my own, I have hereto afiixed, my signature in the presence of tWo Witnesses.
