Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed May 2, 1905. Serial No. 258,520.

To {rv/l H'm'nz, it Wawy concern:

Be it known that I, ALEXANDER B. Drouin, a citizen of Canada, residing' at Brandon, in the Province of Manitoba and Dominion ot' Canada, have invented new and useful V[mprovements in Grain-Doors, oil which the following is a specilication.

My invention pertains to grain-doors for freight-cars; and it contemplates the provision of a simple, strong, and durable grain-door arranged to open outwardly or away from the contents of a car and one which is adapted to be opened and closed with but a minimum amount of eti'ort and which when not in use may be so positioned in a car as to take up but very little space.

Other advantageous features ot' the invention will be fully understood from the following description and claims when taken in connection with the accompanying drawings, forming' part of this specification, in which- Figure lis a side elevation of a car equipped with two of my novel doors, the said doors being shown in their closed position. Fig. 2 is a horizontal section taken in the plane indicated by the line 2 Q of Fig'. l. Fig. 3 is a similar view illustrative of the manner in which the door is opened outwardly. Fig. 4 is a detail horizontal section illustrative of the manner in which the doors are positioned inside ot' the car and out of the way when said doors are not in use, and Fig'. 5 is a detail view of one of the side stiles of the door-frame.

Similar letters designate corresponding parts in all ot` the views of the drawings, referring to which- A is a Jfreight-car body provided with the usual door-opening t and outer sliding door I for closing said opening, and B B are stiles at opposite sides o't' the opening a'. Each of these stiles is provided in its inner side with a recess c, of angular form in cross-section, which extends from a point adjacent to its lower end to an intermediate point in its height, and a recess (l, of rounded form in cross-section, which extends from a point adjacent to its upper end down to the recess c, for a purpose presently set forth.

C C are upright rods arranged adjacent to the stiles B and having' crank-arms at their ends pivoted at f to the body A, whereby they are adapted to be swung outwardly and inwardl y, and D D are the doors, oi' which there is one on each rod C. These doors D are similar, except that one is arranged to swing outwardly toward the right and the other outwardly toward the left, and therefore a detailed description ot' the one shown in Figs. 2 and 3 will sulice to impart a delinite understanding' ot both. The said door D, Figs. l and 2, comprises a main section g, having a shoulder /t at its inner side and one or more notches in its free end, hinge-pieces I, carried by said section and movable horizontally and vertically on the rod C adjacent to one stile B, an auxiliary section fm, hinged at one end to the inner side of the main section g, as indicated by n, and havingl its free end arranged to seat in the recess c ot' the other stile B, after the manner illustrated in Fig. 2, and turn-buttons p, carried by and journaled in the auxiliary section fm, and adapted, in the position shown in Figs. l and 2, to hold said section m fiat against the section g, with the hinged end of the former abutting against the shoulder /t ot' the latter, and in the position shown in Fig. 3 to permit the free portion of the section g/ to swing away from the section lm, as in opening the door.

In the practice ot' my invention when the doors D are in use they are superposed as shown in Fig. l and are secured in such positions by virtue ot' the sections f/ and nt ot' each being held together through the medium of the turn-buttons p. Then it is desired to open one ot' the doors-the upper door, for instance-it is simply necessary to turn the turn-buttons p otl said door into alinement with the notches in the section g/ thereo't' and then swing said section f/ outwardly on its complementary rod C. This will withdraw the Jr'ree end of the section fmy from the recess of the stile in which it seats, and the door as a whole may then, because ot' the swinging' rod C, be swung' to the left and against the outer side of the body A. To close the door, the operation described is reversed, and when the free end ot' the section m is disposed in theA recess c of its complementary stile B the turn-buttons p are turned to the position shown in Figs. l and 2, when the sections y] and m will be held together and the door socurely locked in its closed position. lVhen it is not desired to use the doors D, as when the car is to be used for the transportation of 'freight other than g'rain, the doors are moved upwardly on their complementary rods C until their hinge-pieces l are in the recesses I of the stiles B and are then swung into the positions shown by dotted lines in Fig. l against the inner sides of the side walls ot' the body A and out of the Way.

IOO

Having described my invention, what I claim, and desire to secure by Letters Patent,

lS- 'A l. The combination of a car-body having a door-0pening, an upright, horizontally-swinging rod arranged at one side of the door-o pening and having c1ank-arms pivoted to the body, a door comprising sections hinged t0- gether and having' outer ends arranged when the door is closed to rest back oi' the side wall of the body and also having the outer end of one section pivoted on the said upright rod, and means for detachably holding the sections together to secure the door in its closed position.

2. The combination of a car-body having a door-opening and upright stiles at opposite sides of said opening; said stiles having lower recesses c andupper recesses Z in their inner sides, upright rods arranged adjacent to the stiles and having crank-arms at their ends pivoted to the bottom and top oi' the body, superposed doors one of which is arranged to swing horizontally and move vertically on each rod; said doors respectively comprising sections hinged together and having outer ends arranged when the door is closed to rest in the recesses c of the Stiles, and means for detachably holding the said sections of the doors together to secure the doors in their closed position.

In testimony whereoil I have hereunto set my hand in presence of two subscribing witnesses.

. ALEXANDER B. DICKIE.
