b (ZZZ whom it may concern:

lie it known that l, Tnonas J. N AULTY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Door-Operating Mechanism for Passenger-Cars, of which the following is a specification.

The main object of this invention is to provide means for operating the doors at the side of a platform of a passenger car from a point in close proximity to the eonductors station.

A further object of the invention is to locate the operating mechanism overhead so that it will not interfere with the ingress and egress of passengers.

The invention also relates to further details of construction which will be fully de scribed hereafter, reference being had to the actannpai'iying drawings, in which Figure l, is a sectional plan view of one end of a passenger car, illustrating my invention; the doors being in the closed posi tion; Fig. 2, is a sectional view, similar to Fig. 1, with the doors in the open position; Fig. 3, is a transverse sectional view on the line 35, Fig. 1.; Fig. 4, is a view of a portion of the car illustrated in Fig. 3, showing the mechanism in position when the doors are open; Fig. 5, a transverse sectional view of the platform of the car, illustrating a differentarrangement of the step operating mechanism; Figs. 6 and T, are views of another modification, and S and 9, are views of modified forms of the means for turning the shaft.

A is the body of the ear.

B is the platform and in the present in stance the bulkhead or transverse partition has two independent doorways; the doorway a being for the ingress of passengers and the doorway a being for the egress of passengers. These doorways are separated by a panel 0 and extending from this panel to one side of the car is a rail (l. The conductors station is on the platform within the rail directly back of the panel a. The rail (1 is attached to a standard C which extends from. the floor of the platform to the roof of the car. The rail divides the platform into ingress and egress passageways b?/ respectively, and these passageways communicate with the doorways a a in the bulkhead of the car. This is known as a prepayment type of car. In the present instance the platform is inclosed at the end by av vestibule easing B and at one side by a panel a and a sliding door (2.

DD and I F are the door sections which close on one side of the platform. The door sections D-D close the ingress passageway b of the platform and the door sections F-F close the passageway b. The door section I) is mounted in the present instance on a vertical hinged pintle or shaft land the door section D hinged to the door section D while the door section F is mounted on a hinged pintle or shaft H and the door section F is pivoted to the door section F. The hinges are so arranged that the door sections I) and F swing outnrd, while the door sections D and F swing in against the sections I) and F, as clearly illustrated in Fig. 2.

On the upper ends of the pintles or shafts I and H in the present instance, are arms 1. and A respectively, which are connected by rods z" and it to the operating wheel N. The rod 72. is connected to a head a pivoted to a crank pin a on the wheel N, and the rod 2' is pivoted to a head n also on the crank pin a but on theopposite side of the wheel N, as illustrated in Fig. 1. This wheel is mounted on a shaft M, having its hearings in brackets m, secured to the roof of the car by any suitable means.

The operating wheel N is grooved and mounted in the groove is the operating cord a which is attached to the wheel midwayof its ends and on each end of the cord are hand-holds s and 8 clearly illustrated in Fig. 3. These hand-holds are within easy reach of the conductor so that when he graspsone hand-hold the operating wheel N is turned a partial revolution, shifting the crank pin'n from a position on one side of the shaft N to the opposite side of the shaft, thus opening or closing the doors. The rods 7i and i are bent near the point where they are connected to the heads a and a? so that the pivot pin can pass over the center when the doors are closed, as in Figs. 1 and 3, and thus lock the doors in their closed position. The doors can be so arranged that the crank pin may be on a direct line with the shaft M or slightly below it when the doors are in their closed position, as illustrated in Fig. 3, and on the first movement of the wheel by turning down the hand hold a the crank pin a is raised above the line of the shaft and immediately releases the doors and on the continued movement the doors are turned to the open position, as illustrated in Fig. 2, and the crank pin assumes the position illustrated in Fig. 4c. The handhold 5 will then be in the lowest position and the hand hold 5 will be raised.

In order to operate the step simultaneously with the doors I may connect the step operating means directly with the pivoted shafts of one of the doors, or I may connect it with the operating wheel, as desired.

In Fig. 3, I have shown the step operating means connected to the pivot shaft I of the door D. This shaft extends, in the present instance, through the platform and secured to its lower end is an arm 2' which is connected by a rod 25 to a bell crank lever T, Figs. 1, and 3. This bell crank lever is pivoted at t to a bracket on the arm of the platform. The other arm of the bell crank lever is connected by a rod 15 to a. bearing p, on the step P, so that when the door I) is moved to the closed position, as illustrated in Fig. 1, the step will be turned on its pivot to the position illustrated in Fig. 3, but when the door is opened, as in Fig. 2, the step is lowered into position, so that passengers can enter or leave the car.

In Fig. 5, I have shown a rope wheel T mounted in a bracket located under the platform of the car and an operating rope S passes around this rope wheel and around the operating wheel N at the roof of the car. The wheel T is connected to the step P by a rod 75 so that when the conductor pulls upon the rope in either direction, the step is operated simultaneously wit-h the door.

In Figs. 6 and 7, I have shown an arm N on the shaft M to which the rods h and z" are connected and the operating wheel N is located close to the panel 0 and in this instance the operating ropes 8 pass around a wheel .9 mounted on a stud secured to the panel. The conductor may either grasp the ropes s or may turn the wheel 8 to operate the doors. The wheel may be provided with a suitable handle, if desired.

In Fig. 8, I have shown a segment N in place of the wheel N and attached to this segment are two independent cords 8*.

In Fig. 9, I have illustrated a sprocket wheel adapted to which is a chain 8 having hand-holds at each end.

By the above construction, it will be seen that the operating mechanism for the door is located above the head line of the passengers and is completely out of the way of any one entering or leaving the car, but is within easy reach of the conductor.

The doors are locked in the closed position by the mechanism without separate locking means and the depending guards are within the conductors space formed by the dividing rail, consequently there is no liability of the cords striking the passengers entering or leaving the car.

The arrangement of the car body and the platform may be modified without departing from the essential features of the invention.

I claim 1. The combination of a door; a vertically arranged pivot on which the door is mounted; a horizontal overhead shaft located above the door; a wheel on said shaft; an operating cord hung from the wheel; a crank pin on the wheel; and a rod connecting the crank pin with the pivot of the door so that, as the wheel is turned, the door will be opened or closed.

2. The combination in door operating means, of a pair of hinged doors; a shaft mounted in overhead bearings; an operating wheel on said shaft; a crank pin on the wheel; heads pivotally mounted on the crank pin; a rod connecting one of said heads with an arm on one door; a rod connecting the other head with an arm on the other door; and an operating cord depending from each edge of said wheel.

The combination in door operating means, of a hinged door; an overhead shaft; an operating wheel thereon; a crank pin on said wheel; arod connecting the crank pin with an arm on the pivot of the door; and a cord depending from each edge of the wheel, so that on pulling one end of the cord the door will be opened and on pulling the other end of the cord the door will be closed.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
