Patented J an. 2, 1917.

Application led November 21, 1912. Serial N o. 732,709.

T0 all whom it may concern Be it lmown that I, JOSEPH NRnn GIN- eRAs, a subject of the King of Great Britain, residing at Thetford Mines, in the Province of Quebec7 Canada, have invented certain new and useful Improvements in Grain- Doors; and I do hereby declare that the following is a full, clear, and eXact description of the same. 1-

This invention has for an object to provide a grain door of greater simplicity than those heretofore used and which will permit of a more rapidl discharge of the grain.

A further object is to provide a door of this type which will be easily applicable to ordinary box'cars; which will present no permanent obstructions adjacent the door opening, and of which certain parts may be employed to protect the ordinary door casing of the car from injury when the grain l door is not in use. v

A still further object is to construct the door in a manner to render it diticult or impossible for the grain shipper to nail it in place. For further comprehension however of the invention and of the objects and advantages thereof reference will be had to the following description and appended claims and to the accompanying drawings forming part of this specification in which similar reference characters indicate the same parts and wherein:

Figure l is a face embodying my invention showing it in position in the car door opening and looking from the interior ofthe car. Fig. 2 is a transverse vertical section on the line 2-2 Fig. 1. Fig. 3 is a horizontal section on the line 3 3 Fig. 1. Fig. 4 is a perspective view of one side of the door frame showing the door post strip turned inwardly. Fig. 5 is a perspective view of the door, taken from the outside of the car, and showing it falling outward after the retaining means has been unlocked. Fig. 6 is a view similar to Fig. 3 of a modication.V

In the drawings I have shown my improved grain door applied to a box car of ordinary construction, the side of the car being indicated at 1 and the roof and flooring at 2 and 3 respectively. The casing of the usual side door opening is shown at 4, and the door opening (the lower portion view of a grain door4 of which is adapted to be closed by the grani door) is indicated by the reference numeral 5. Y

The grain door proper is shown at 7 and may be of anyl'suitable detail construction, being here shown ascomprising cross boards reinforced by the battens 8. This door is adapted to be placed within the door opening 5, being of less width than the latter, and to retain it in place and form a tight joint between the sides thereof and the adjacent sides of the permanent door casing 4 removable or adjustable door post strips or door retaining strips are provided which are mounted upon the casing 4 and engage the sides of the door 7. These adjustable door post strips, are preferably formed of angle bars one flange 9 whereof is turned inwardly toward the interior of the car and rests in flat contact with the face of the door casing 4 while the other flange 9 projects into the door opening and overlaps the sides of the lgrain kdoor on the outside thereof and supports it against outward movement, the strips being ladj ustably retained in place by suitable means. The retaining means which I have devised and here illustrated comprise a pair of staples 10 fixed to the door casing4 one on each side of the door opening andupon which the strips are freely hung, the upper 'ends ofthe inturned flanges 9 being formed to present short vertical slots 11 through which the staplelegs pass. This slot and staple connection forms a universal joint by which the door post strips are secured to the frame 4 to permit of the strips swinging in different directions for a purpose to be pres! ently pointed out.

The lower ends of each of these door post strips is retained in position byvinner and outer detent latches, 15 and 16 respectively, hinged as at 15 and 16 in vertical grooves 17, 18 in the casing 4 and adapted to project across the outer and inner sides respectively of the door post strips, the inner latches 16 being located somewhat higher than the outer latches 15 and adapted also to prevent the grain door from falling inward when the car is empty. l

When the car is to be unloaded one of the latches 16 is thrown upward leaving the lower end of the post strips free and allowing the weight of the grain to throw the door outward, the angle bar swinging freely outward also. .i

`When the car is to be used as an ordinary box car the latches l5, 16 are thrown upward and lie entirely concealed within the grooves 17, 1S and out of the way of objects passing through the door opening. The strips '8, 9 are also turned inwardly to the position shown in full lines in Fig. l in which they cover the inner corners of the door casing l and are not only out of the way but also serve to protect the door casing from injury. The universal connection between the upper ends of the strips and the casing, which has been described above, permits both the outward swinging of the strips to release the grain door and the inward turning to the position shown in dotted lines in Fig. l.

As shown in the drawings small angular lugs 19Vmay be provided on the car floor adjacent the inner corners of the door casing to-engage the lower ends of the strips and retain the latter in their inturned position, the slots 11 permitting the strips to be raised sufliciently to clear the lugsV when moved from one position to the other.

When the grain door is not in use it may be hung in any convenient manner within the car being preferably permanently at taclied thereto by a loose chain 20 to prevent its removal.V j

In Fig. G l have shown a modification in which only'one of the adjustable Vdoor post strips is employed, the opposite side of the grain door being retained in a groove or recess 25 formed in any suitable manner in the door easing. l/Vhen the latch 16 is released the side of the door will swing out in the same manner as shown in Fig. V5.

What I claim is as follows:

l. ln a ear having a door opening, a strip formed of angularly disposed flanges andY being adapted to inclose the lower portion of theA inner corner of one of the side Vposts of such door opening, one iiange of the strip overlapping that surfaceof the side post which faces inwardly of the carrand theV other flange of the strip overlapping that surface of the mentioned side` post Y* which facesinwardly of the door opening and means for hinging` the strip to said door post, whereby the strip may be swung intoV the Vdoor opening Vto a position with one flange flat against the post and the other flange Yprojecting. from the post into the door opening.VV f

2. -In a oar,fthe combination with a grain eop'ies'of this pate n1; may 'neY obtained for door, of a door post strip adapted to engage the side of the gra-in door, and means providinga universal joint Connection between the upper end of suchstrip and the car to pe 1mit of the strip being moved in different directions out of theposition wherein it is adapted to engage with the door, for the purpose set forth. l

V3. n a car, the combination with a door casing presenting a door opening, of a grain door, a door post strip within the door opening adapted to engage the side of the grain door, releasable means retaining the lower end of the said strip in position, and means providing a vuniversal joint connection between the upper end of such strip and the door casing to permit of the lower end of the strip being swung bodily outward when the said locking means Eis released, or the strip being swung around the door casing out rof the position wherein the strip is adapted to engage with the grain door.

ii a! car, the combination Vwith a door easing presenting a door opening, of a grain door, a door post strip within the door opening adapted to engage the sidel of theV grain door,.releasable means retaining the lower end of the said strip in position, and including a detentY latch pivotally mounted in the ear and adapted to project across the face of the door, and means providing a universal joint connection between the upb 3er end of suoli stri a and the door casing to permit of the'lower endrof the strip being swung bodily outward when the said locking means is released, oi the strip being swung'around the door easing out of the position wherein the strip is adapted to engage with the grain door.

lin a car, the combinationwith a grain door, of a pair of door post strips of angular cross section adapted to engage the sides thereof, slot and staple connections between the upperV 'end' of such strips and the carl` whereby the strip may be swung in different V.directions-out ofthe position wherein it is adapted to engage with the door, and de- Vtent latches pivoted adjacent such strips and adaptedto project across the inner and outer Vsides thereof.

In testimony whereof, I have signed my name to this specification, in theY presence of two subscribing witnesses. 1
