Specification of Letters Patent. Patented Deg, 18, 1917,

Application filed March 17, 1915. Serial No. 14,980.

To all whom itma'y concern;

Be it known that I, FRANK J. GILROY, a citizen of the United States, residing at Buf falo, in the county of Erie and State of New York, have invented certain new and useful Im rovements in Car-Doors, of which the fol owing is a specification, reference being had therein to the accompanying drawing. I This invention relates to car doors which, when shut, are in close engagement at allperipheral points with devices on the car, and which normally rest uponrollers mounted upon the exterior of the car, below the path of the door, in position to support the door whether in open or closed position. The objects are to provide a construction adaptable for'use with thin metal doors or with new or old wooden doors; that obviates the necessity for internal boarding to prevent the escape of loose granular material with which the car maybe loaded; that fully excludes water; that will stand rough usage; that cannot, open or closed, move outward from the car wall; and that is extremely simple and inexpensive.

In the accompanying drawings,

Figure 1 is a side elevation of a portion of a car provided with my novel devices.

Figs. 2, 3, 4, 5,-6 are, respectively, sections on the lines 2-2, 3 3, 6-6, Fig. 1.'

Fig. 7 is aovlew analogous toFig. 1 showing a smaller portion of a car provided with a wooden door.

, Figs. 8, 9, 10,11 are sectional viewsshowing construction when a wooden, door is used and corresponding to Figs. 2 3, 4, 5, respectively. v

- Fig. '12 is a horizontal section through a rear door-post and illustrates a modified construction.

Fig. 13 is a vertical section of the belt rail portion of the post of Fig. 12.

In these drawings, A represents the side wall of a car rovided with a door having a body B of thin sheet steel reinforced at its forward edge by a T-bar C, at its upper edge by a bar D, at its rear margin by an angle bar E, and at its lower edge by a channel bar. F made wide near the door angles and overlapped by the bars 0, E, to which it is riveted or otherwise rigidly secured. Across the body of the door extend horizontal T-bars G which, like the marginal. members just mentioned, are rigidly secured to the body B and, at their ends, to

the bars C, E, which they overlap. To the angle bar E is fixed a second angle bariH, one flange H of which forms a hook parallel to and slightly within the 'plane' of the body B.

To the exterior of the car, below the plane of thecar floor I (Fig. 3 a door-engaging member J is secured. This member is pro vided, along its upper side, with a down wardly extending orhooked flange J with which the bar F on the door engages, and .belowthe hook the member extends outward beyond the plane of the door and is pro- -vided, below" the. edge of the door, with broad vertical openings in which are cylin-- 1 drical rollers J mounted on shafts J and projecting slightly above the plane ofqthe outwardly extending portion of the member J, which is rigidly secured in place by bolts J passing through the member, the car sill .I', a strengthening bar I and a three web angle'bar I and also further secured by rivets I, preferably,- as shown in Fig. 9.

.The upper side of thedoor is overlapped by a downwardly inclined angle bar K securedby bolts K passing through the upper portion of the car frame and like the member below extending rearwardly from the door openingso that when the door is fully opened its upper and lower margins are still securely held close to the car wall.

The up or edge of this bar lies wholly below the oblique faceof a wood strip K which prevents water from passing behind the bar. nThe forward margin of the door when the latter is'closed, as in Fig. 5, lies within the flange of a'braced member L secured by bolts L passing through the door post L and at the opposite edge ofthe door the flange assing through the be secured by ordinary devices with such safety devices as may be selected.

.of the angle bar H engages the flange of an angle bar M forming a sort of j'amb-and secured by bolts M door post M and paral e1 to'the wall of the Nearly all parts of the door described a re of commercial steel obtainable everywhere, and

hence-its cost is "cry little more than the costof a wood door, or is even lessif salvage on old doors be considered. It is however desirable to obtain similar advantages without discarding wood doors already in use, and Figs. 7, S, 9. 10. 11 show modificationswhich may be used with wood doors. In these figures, 0 represents a wood door having its forward and upper margins covered by angle bars 0 while its rear and lower edges are provided with channel bars 0 0 The front edge of the closed door engages under a bar P similar to the bar Lof the primary form, and the channel bar 0 engages a bar Q analogous to the bar M of Fig. 4. As in the other form, the door normally rests on rollers R, which in this instance however are mounted in separate brackets R, secured by bolts R passing through the car sill and a three-web angle bar member R to the lower flange of which the brackets are also riveted. The channel bar forms a smooth continuous surface, at the lower-edge of the door, to rest upon the rollers. In this case water is excluded from the inner face of the bar K by a thin metal sheet S, which may be of copper, o erlapping the upper flange of the bar and lying between the rabbeted edges of two wood facing members secured on the carframe.

Instead of the common door post illus trated, I may use the channel iron post V, shown in section in Figs. 12, 13. Tothis post the usual belt rail V is secured by a' riveted bracket W and above and below the belt rail wood members V are secured to the post V to receive the external and internal sheathing X, X. The channel iron post is made wide enough to project outside the plane of the outer sheathing so that its outer flange V may be engaged by the hook, such as H, at the rear edge of the door.

It may be noted that ice is unlikely to interfere with the working of the door since the latter rests upon ungrooved rollers and? does not come into contact with parts surrounding the rollers. I

-What I claim is: I

1. The combination with a freight car, of parallel, oppositely turned external horizontal flanges fixed to the car above and below itsdoor opening, respectively, a doorv providednear its upper and lower sides, respectively, with flanges engaging over and under the flanges first mentioned, respectively, cylindrical door-supporting rollers fixed to the car below the door and projecting above the outer portions of their mountings and normally sustaining the weight of the door and maintaining the flanges out of door-supporting and friction producing con 3 cylindrical rollers mounted on the car below the door, projecting above adjacent parts extending farther outward from the plane of the door, and in position for carrying practically the entire weight of the door by maintaining the flanges out of door'supportingand frictional contact at their horizontal faces.

In testimon' whereof I aiiix my signaturev inpresence 0 two witnesses.
