CHARLES A. sorritoxuafor OAK ran-K, ILLINOIS.

CAR-DOOR;

Specification of Letters Patent. Application filed June 22, 1907. Serial No. 380,339.

To all whom it may concern. I Be it known that I, CHARLES A. SGHROYER,

a citizen of the United States, residing at Oak Park, in the county of-Cook and State of Illinois, have invented certain new and useful Improvements in Car-Doors, of which the following is a. specification.

The object of my invention is toprovide a car door that shall be flush with the sides of the car when closed, together with means I for Supporting the door, for forcing it in and out of the rabbeted door opening, for draining the top of. the car in such manner that the drippings will fall outside of the door, and for other purposes hereinafter more particularly set forth and claimed.

In the drawingsFigure '1 is a side view of part of a car equipped with my invention. Fig. 2 is a plan view of the upper guide track. Fig. 3 is a front elevation, partly in section, of the upper guide track. Fig. 4 is a transverse sectional view of thedoor and door opening. Fig. 5 is a similar View, showing the means for forcing the door in and out of the rabbeted opening, the door being shown in its outer position. Fig. 6 is.

a similar view showing the door in its inner posit-ion. Fig. 7 isa detail view of the lower corner of the track and of the shoe attached thereto. Fig. 8 is a detail view of' the shoe.

Above the car door andextending over the door opening and beyond the opening a distance substantially equal to the width of i the door I place a filler block 1. Above the door opening the filler block is channeled out, as indicated at 2, for the purpose of providing space for the forward extension of the door hanger 3, which embraces the guide track 4 secured to the outer side of the filler block 1. Beyond the door opening the filler block is formed flush with the upper edge of the guidetrack 4,-as shown in Figs. 5 and 6. Over the door opening where the guide track 4 projects above the channeled out portion of the filler block openings 5 in the form of grooves in the front face of the filler block are provided for the purpose of carrying off the drippings of water from the roof and causing them to fall outside of the door. When the door is open the drip-- pings from the roof also fall outside of the same, by reason of the fact that the part of the filler block beyond the door opening is flush with the upper edge of the guide track,

and inclines downwardly so that the dripopening when the .door is the door.-

pings fall beyond the'guide track outside of A The doorv is suspended from the guide track 4 by means .of a hanger. 6 located at the upper edge of the door near its left-hai1d edge. This hanger is'bolted. to thedoor in the usual manner, and the guide tra'ck4 is embraced by 'theupwardly extending part .3 of said hanger. At its lower edge the door is supported by the door shoe 7 which rests upon the lower guide rail 8,'said guide rail. extending from the right-hand edge ofthe door opening along the side of the car a distance substantially equal to the width of the door. Thus the door [18 .entirely'supported by the hanger 6 and shoe 7, and is held against the side of the car by the

guide tracks

4 and 8 which lap over the upper and lower edges of the door, respectively. r

The door is adapted when closed to lie shown in Figs. 4, 5 and 6 of the drawings. The upper guide rail 4 is curved inwardly at the left end thereof sufficiently to carry the. left edge of the door into the rabbeted position; In order to force the right-hand edge of the door into the rabbeted opening,

.1 provide a rod '9 pivoted in bearings 10 fixed to the door. The upper and lower ends of the rod 9 are formed with offset portions or crank arms 11 which lie back of the upper and lower"

guide tracks

4 and 8, respec-' tively. A handle 12 is provided by means of which the rod 9 may bearings 10. .By rotating said rod from the position shown in Fig. 5v to that shown in Fig. 6, the door is forced into the rabbet-ed l opening, as illustrated in those figures. By rotating. said rod in the opposite direction the door maybe withdrawn from'the ope11- ing. Then closed, therefore, the door is held securely in the rabbeted door opening at the left-hand edge by means of the engagement of the hanger with the inturned end of the guide track 4, and the left-hand edge of the door is held in said openin by means of the rod 9. A bracket 13, 153 is provided for securingthc door in closed position. For the purpose of limiting the movement of the door when opened, I provide a stop 14, and for the purpose of securing the door against accidental displacement when opened, I provide a pawl 15 co-acting c fiush with the side of, the car, and the door. opening. is rabheted for. this purpose, asv

moved to closed a with the notch 16 in the lower guide rail 8.

The lower handle 17 is provided for the purpose of operating the door from the ground, and the upper handle 18 for the purpose of operating it from a freight-house platform.

The shoe illustrated in detail in Figs. 7 and 8 of the drawings is provided with de pending lips and 31 adapted to engage the outer and inner sides, respectively, of the lower guide track. As shown in Figs. 7 and 8, the depending lip 30 is spaced in advance of the lip 31 in such manner that when the door is moved to closed position the lip 30 will pass beyond the end of the lower guide rail 8, thus permitting the door to be forced inward into the rabbeted opening. The shoe 7 is also provided with a depending lug 32. When the door is opened or partially opened, its weight rests upon the under side of the shoe between the two lips at the space designated 33. When-the door, however, is closed and forced into its opening the shoe becomes disengaged from the guide rail 8 and its weight is borne upon the lower end of the depending lug 32 which bears upon the lower side of the door opening, as shown in Fig. 6 of the drawings.

From the foregoing it will appear that I have provided means whereby a flush door may be supported at two diagonally opposite corners. The hanger at the upper corner is permanently in engagement with the upper guide rail. The shoe at the lower corner, however, engages the lower guide rail only when the door is wholly or partially opened. By means of my improved shoe, however,

provision is made for properly supporting the door when out of engagement with the lower guide rail. It will be observed that the bar 9, by means of which one edge of the door is forced into and out of the rabbeted opening, always lies back of the lower guide rail and in position to co-act therewith.

What I claim is:

1. A car having a rabbeted door opening, a door, a lower guide track extending from one side of the door opening along the side of the car, a shoe secured to the lower corner of the door, and outer and inner depending lips upon said shoe adapted to engage the outer and inner sides, respectively, of said guide-track, said outer and inner lips being off-set in the direction of the width of the door, the lower edge of said inner lip being adapted to rest upon the lower edge of the rabbeted door opening and to support the door in such manner that when the door is closed the outer lip will disengage the guide track while the inner lip still lies behind the same.

2. A car provided with a rabbeted door opening, a door, a lower guide-track,.and a shoe attached to the door and provided with lips adapted to engage the guide-track and with a depending lug adapted to rest upon the lower edge of the door opening and support the door when the lips are disengaged from the guide-track.
