CAR-000a.

SPECIFICATION forming part of Letters Patent No. 643,655, dated February 20, ieoo.

Application filed May 4, 1899. Serial No. 715,632. (No model.)

To all whom it may concern:

Be it known that I, GRAHAM P. JONES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in Oar-Doors, of which the following is a specification.

My invention relates to car-doors, andparticularly to that class of car-doors which normally rest upon cam-hangers and cambrackets which serve when the door is lowered to throw it laterally into engagement with the side of the car to bind it firmly in place and to prevent any movement of the door, whether the latter covers the doorway or not, and which are raised by suitable apparatus into operative position for movement back and forth upon the rail to cover and uncover the door-opening.

The object of my invention is to provide certain improvements in the operating mechanism of the raising and lowering devices whereby this mechanism may have either a lateral movement or a straight downward pull.

2 5 This object I accomplish as illustrated in thedrawings and as hereinafter set forth.

The invention consists of an operating mechanism or device for the raising and lowering means which may be used by the op- 0 erator to raise the door either by a lateral or vertical movement.

This invention may be applied to any form of sliding door which is arranged to be raised and lowered to and from its operative posi- 3 5 tion with respect to the rail on which it travels by suitable levers or equivalent means, but is more particularly applicable to doors for freight-cars, and for the purpose of illustration I have shown it in the drawings applied to such purpose.

In the accompanying drawings, which form a part of this specifications and in which like letters of reference indicate like parts in the several views, Figure l is a side elevation of 5 a car-door embodying my improvements and showing the devices in position when the door is at rest. Figs. 2 and 3 are similar elevations representing the door in its operative position for movement and the two methods by which the operating mechanism may be employed.

Figs. 4 and 5 are cross-sections of the doorway, the door being shown in Fig. 4c in its position of rest snug against the side of the car andin Fig. 5 in its position for running along the supporting-rail. Figs. 6 and 7 are enlarged detail views illustrating the operating device in the positions shown in Figs. 2 and 3, respectively.

In the drawings the reference-letter A indicates the side of the car, A the car-door, and a the rail adapted to receive the sheaves a, which support the door when it'is moved to cover and uncover the door-opening. A cam bracket a of the structure and character fully shown in Figs. 4 and 5, is provided at the lower right-hand corner of the door-opening upon its run side, upon which the door rests when lowered and which forces the door laterally against the side of the car to prev vent its movement. At the lower left-hand 7o corner of the doorway a supporting-bracket a is located, which may or may not be similar to the cam-bracket a and upon which the door rests in part when closed over the dooropening.

The sheaves a are journaled in the raising and lowering levers a, which are pivoted at their opposite ends to cam-hangers a secured at the upper corners of the door and extending inwardly over the rail. These hangers are provided with cam-faces a, which operate in conjunction with the rail to force the door laterally'against the car-body as it is lowered to its normal position, the rail of course being held away from the side of the car, so as to leave room for the free movement of the overhanging portions of the hangers, all as clearly shown in Figs. 4 and 5.

The inner ends of the levers a are slotted and are connected by a bolt which passes through these slots to the connecting-rod B of the operating mechanism, which extends downwardly close to the outer face of the door, preferably in its central line to about the middle of the door, and which constitutes the 5 upper part of the operating device of the raising and lowering levers. The lower part of this operating device is composed of an operating or lower rod B, which also extends downwardly nearly to the bottom of the door in continuation of the upper rod. The rod B is provided with a handle I) at its upper and lower ends and passes freely through a bracket 0, which is located at about its center and secured to the door in properly-adjusted position by means of bolts passing through elongated slots in its ends. The bracket is provided with an upwardly-expanding passage c for the rod B, as clearlyshown in Figs. (5 and 7, the width of the passage at its lower or smaller end being somewhat greater than the width of the rod. The rod 13' is provided with a plate I) in proximity to the lower edge of the bracket,which is preferably of the form shown in the drawings, being rigid on the rod and slightly greater in width.

The door normally rests upon the camhangers a and upon one or both of the brackets a a according as it is in position over the doorway or to one side thereof, the raising and lowering levers and the operating device therefor then being in the positions indicated in Fig. 1 and the weight of the door being OK the sheaves, as clearly shown in Fig. 4. \Vhen it is desired to move the door laterally to cover or uncover the door-opening, the operator may raise it to its operative or sliding position upon the sheaves either bya direct downward pull upon either of the handles b or by a lateral movement of either of these handles. If the operator drawsthe handle vertically downward or exerts a direct downward pull, the parts will assume the positions shown in Figs. 3 and 7, the rod B passing freely through the bracket G. hen the operator exercises a lateral pressure or strain on either of the handles, the rod 13 turns upon the bracket as its fulcrum and throws the joint of the rods 13 B slightly to one side, the parts then taking the positions shown in Figs. 2 and 6. The plate b serves as a means to prevent the rod B from moving upwardly through its bracket under any accidental strain in that direction and also aids in insuring the pivoting of the rod on the bracket. Either of these operations serves to draw downwardly the raising and lowering levers and to raise the door off its cam-hangers and brackets, the sheaves serving as fulcrums, to its operative position, (see Fig. 5,) in which it may he slid back and forth.

From a consideration of the foregoing disclosure it is apparent that my invention embodies an organization and arrangement of parts in which the door maybe moved at any position it may occupy either by a pivotal or by a sliding motion of its operating device. It may be moved from its normal positions of rest when either closed or open or from any intermediate position by either of these movements of its operating device, and the handles of the operating device may be moved in either direction, either to the right or to the left, about its pivot or fulcrum in any position of the door.

It is often desirable to employ a closing strip or cleat d on the run side of the dooropening to make a dust-proof closure. lVhen this is done, it is necessary to provide some means to move the door laterally or away from the side of the car as it is raised, so that the door will clear the cleat in its movements. For this purpose a wedge or incline D is attached to the door-opening frame at the upper right-hand corner, so that it is in the path of the door as the latter is raised and serves to force it laterallyaway from the car, as shown in Fig. 5.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a sliding door,- and mechanism for moving it to and from its sliding position, of a device adapted to oper ate the lifting and lowering mechanism in any position of the door by either a lateral or a sliding movement.

2. The combination with a sliding car-door, and mechanism for lifting and lowering it to and from its sliding position, of a device adapted to operate the lifting and lowering mechanism either by a lateral movement in either direction or by a sliding movement.

3. The combination with a sliding car-door, and mechanism for moving it to and from its sliding position, of a device adapted to operate the lifting and lowering mechanism from its normal position by either a pivotal or a sliding movement.

4. The combination with a sliding car-door, and mechanism for lifting it to and from its sliding position, of an operating device for said lifting and lowering mechanism consisting of jointed rods, one of which passes freely through or coacts witha bracket on the door in any position of the door, substantially as described.

5. The combination with a sliding car-door,- and mechanism for lifting and lowering it to and from its sliding position, of a jointed operating device for said mechanism, and a bracket adapted as a guide for said device or as a fulcrum upon which said device may have movement in either direction, substantially as described.

6. The combination of acar-door normally resting in a lowered position upon brackets, levers for raising said door to its operative position, jointed operating-levers, one of which is provided with a plate, and a bracket carried by the door with which said plate coacts when the levers are moved laterally, substantially as described.

7. The combination with a sliding car-door, levers pivotally connected to the upper portion of the door, and sheaves carried by said levers, of a track on which said sheaves run, a connecting-rod pivoted to the levers, an opcrating-rod pivoted to the connecting-rod and provided with a plate, and a bracket through which said operating-rod freely passes and with which the plate coacts, substantially as described.
