WALTER L. CONWELL, OF MONTCLAIR, AND ALLEN EDWARD OSTRANDER, OF RIDGE- WOOD, NEW JERSEY, ASSIGNORS 'TO TRANSPORTATION UTILITIES COMPANY, OF NEW YORK, N. Y., A CORPORATION OF WEST VIRGINIA.

RAILWAY-CAIR- noon.

To all whom it may concern Be it known that we, WALTER L. CoNwELL andALLEN E. OSTRANDER, residing at Montclair, Essex county, New Jersey, and Edge- Wood, Bergen county, New Jersey, respectively, and being citizens of the United States, have invented certain new and useful Improvements in Railway-Car Doors, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understoodthat the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is an elevational view of a fragment of a car side equipped with a door having door fixtures formed and attached to the door as contemplated in accordance with the present invention. Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1. Fig. 3 is a vertical sectional view taken on line 33 of Fig. 1. Figs. 4 and 5 are horizontal sectional views taken, respectively, on lines 4-4 and 55 of Fig. 1. Fig. 6 is an edge view of the hanger showing the lugs 10 extending laterally from the body of'the hanger.

The object of the invention is to provide a door formed of sheet metal of light weight, which is reinforced by means of corrugations extending verticall and horizontally, and is especially inten ed for use in car construction, though the door is adapted to other purposes.

' One of the objects of the invention is to utilize the door fixtures as means for securing together the sheets forming the doors.

Another object is to provide fixtures of 1' such contour that lparts of the fixtures will rest within channe portions of the corrugations in one face of the door in such manner that torsional disturbances of the connected fixtures and door will be avoided.

Other objects of the invention are economy of manufacture and utilization, with but "sli ht chan'gesin details of formation, of stan ard fixtures which are'well known in theart. I

" Primarily, the-'invention-consists-of par- Specification of Letters Patent. Patented Ma, 10 1914 Application filed July 8, 191a.

Serial No. 777,842.

of door fixtures intended to be used for supporting, locking and guiding the door, which fixtures are so disposed with relation to the corrugations that the contour of parts of the fixtures is utilized to prevent displacement, in addition to which the fixtures are secured to the corrugated sheets of the door by means which connect such sheets together and reinforce the part of the door within the zone of connection of fixtures to the door. I

Referring specifically to the drawings, A indicates the door which, as will be noted in the sectional views Figs. 2, 3, 4 and 5, is composed of parallel sheets B and G, which sheets B and C are provided with corrugations intersecting at right angles and com;

prising channel portions D and ribs E,which ribs outline the channels. The fixtures comprise door hangers, door lockin means and the handle for shifting the oor. These parts are secured to the outer face of the door, as is common in car construction.

Referring specifically to the hanger, it will be noted that said hanger is provided with a bracket 1, an upward extension 2, terminating in an inset portion 33, carrying a supporting wheel or roller 4 and with an integral guide finger 5, and that the track portion for the hanger is provided with an upper flange 6, a vertical web 7 a horizontal flange 8 and a depending vertical flange 9, on the horizontal flange 8 of which the roller 4 travels and the flange 9 laps the upper edge of the door, while the finger 5 of the hanger is interposed between the door and the flange 9.

The bracket portion 1 of the hanger is provided with integral perforated spaced lugs 10, which lugs are spaced vertically and horizontally, as shown in Fig. 6, so that said lugs will occupy and substantially fill the channels D in the face of the door in which they rest, the remaining portions of the hanger lapping the door and extending upwardly above the same as shown.

a It is evident that with a door suspended from above by means of hangersof the type shown, there is a considerable degree of torsion on the hanger, and when rivets alone are used as securing means to connect the hanger to the door there is a probability of the rivets working loose, which would re sult in some lost motion. Owing to the thin metal of which the door proper is composed, this tendency is materially increased, hence it is desirable to protect the connection of the door hanger to the door to avoid such torsional disturbance. This is accomplished by the lugs of the hanger which rest within the channels D, substantially filling said channels, whereby the outstanding ribs E on the outer face of the door will serve as side abutments for the lugs, and to better assist in preventing such torsional disturbance the lugs are spaced apart vertically, the grip of the lugs being assisted by such vertical spacing and by the horizontal spacing shown, so that more than one vertical channel D is occupied by the lugs. It is evident that the horizontal and vertical spacing thus assists in holding the door hanger in position. The vertical spacing of the lugs is indicated because the door hangers are formed of cast metal, which can be better formed with lugs spaced apart both vertically and horizontally as shown, though it is evident that the vertical lugs may be connected by an intermediate web, if desired, though where the bracket is made of malleable iron the lugs may be better annealed when they are formed separately as indicated.

The locking fixture is secured to the door in substantially the same manner as the door hanger bracket, and said locking fixture comprises the plate 20, which is provided with the integral horizontally spaced lugs 21, which, like the lugs of the door hanger, are perforated. The plate 20 has cooperating with it a supplemental locking plate 22, which is connected by hooked engagement with the plate 20, a hooked end 23 engaged with the perforation 20 of the plate 20, as shown in Fig. 4, and rivets 25 secure the lockingplate in position, the same rivets securing the plate 20 to the door, thereby providing a recess between said plates for the ring 25 of the hasp 26.

It is understood that the hasp extends beyond the edge of the door and is adapted to interlock with a suitable stud 30, the usual door sill being employed for that purpose.

The handle on the outer side of the door, by means of which the door is shifted, is of the conventional form, comprising the loop 31, which, like the door hanger bracket and the hasp plate, is provided with inwardly extending studs 32, which studs are perforated for the passage of the rivets 33, adapted to secure said handle in position.

As will be noted in the drawings, the studs 32 are arranged in pairs, one pair at each end of the door handle and the members of each pair being arranged vertically so as to occupy proper positions within the vertical channels in the outer face of the door.

A feature common to the door hanger, hasp plate and to the handle is means to prevent rupture of the thin metal plates forming the-door, this feature consisting of a bar or series of bars 35, resting within the horizontal channels on the inner side of the door and extending far enough horizontally to receive the horizontally spaced rivets of the doorhanger, one of the bars 35 being disposed at the middle portion of the hanger bracket and another of the bars being disposed near the lower portion of the bracket, as-best shown in the sectional view Fig. 2-.

The hasp plate is likewise reinforced in its connection to the door by means of a bar 35 which, as shown in Fig. 4, has suflicient length to receive through it the four rivets shown as connecting the hasp plate to the door. Likewise the handle 31 is connected to the door, the rivets 33 extending through horizontally disposed bars 35 It is to be noted that the bars 3-5, 35* and 35 are suitably perforated for the passage of the securing rivets, and said bars are of substantially the width vertically of the horizontal channels on the inner face of the door, within which said doors are positioned. Thus, it will be apparent that while the door fixtures are connected with the doors by direct rivet connection through the thin metal plates comprising the doors, such metal plates are reinforced within the zone of connection by means of the reinforcing bars indicated and rupture of the sheet metal of the doors is effectually prevented. Suitable back stops, as 87, may be employed and bottom guides, 38, are provided for the lower edge of the door, as is common in car doors.

We claim:

1. In a railway car door, vertically disposed corrugations on the outer face thereof, a door hanger extending above the upper edge of the door and extending downwardly and lapping certain of said vertical corrugations and interlocked with the door against torsional stresses by means of lugs projecting from the hanger inwardly within a channel formed by said corrugations and in juxtaposition to and between outwardly extending ribs outlining said channels, and fixture securing mean projected through said from the fixture intween outwardly extending ribs outlining said channels, and fixture securing means projected through said hollow lugs and through the door.
