rAssEiiGEa-oAR.

To all whom it may concern:

Be it known that I, PEARL N. JONES, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Passenger-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a'sectional plan View of the rear platform of a passenger car, the section being taken on the line I-I of Fig. 2. In this figure, the entrance doors are shown closed, while the exit doors are in their open positions; Fig. 2 is a vertical section on the line IIII of Fig. 1; Fig. 3 is a detail view of a portion of the door-operating mechanism; Fig. 4 is a detail view showin' the pivot roller for one of the doors; %ig. 5 is a plan view of the car step; Fig. 6 is an elevation of a portion of one of the doors; Fig. 7 is a perspective view showa portion of one of the doors and a portion of the upper track for the doors; Fig. 8 sectional view showing part of the door-operating mechanism; and Fig. 9 is a diagram illustrating the door movements. Fig. 10-is a diagram showing a modification.

My invention has relation to passenger cars, and more particularly electric street cars, and has'especial reference to the platform and door arrangement, together with means for operating the doors.

My invention is designed to provide doors for the entrance and exit of cars, capable of separate and independent operation, and which will not only close the entrance to and shit from the car platform or vestibule, but will also prevent access to the car step when closed.

A further object of my invention is to provide doors which will in both their open and closed positions be without substantial projection beyond the side lines of the car and which can be opened and closed in a but little upon the space of-the platform or vestibule.

A still further object of my invention is to provide door mechanism which can be readily controlled by the conductor of the car, and which is simple and effective in its character.

The precise nature of my invention will be best understood by reference to the accompanyi'rig drawings, in which I have Specification of Letters Patent.

' illustrated the preferred embodiment there- Patented July/12, 1910. Application filed December 16, 1909. Serial No. 533,357 i and arrangement of the various parts, without departing from the spirit and scope of my invention as defined in the appended claims.

In these drawings, the numeral 2 designates the platform of a car structure, which isinclosed or vestibuled at one side and at the rear, as shown at 3.

1 is an opening communicating with the interior of the car and which is preferably without doors. I

5 designates the car step arranged at one side of the platform or vestibule. Y

6 designates a bent rail or guard supported by the vertical posts 7, 8 and 9,.and which sage 10 from theexit space or passage 11.

12 designates two doors which control the exit, and 13 two .-other doors which control the entrance. These doors extend from a point near the car roof floor of the car step 5. In order to give clearance in turning corners and to bring these doors well within the side lines of the car, the vestibule and platform are of gradually decreasing width toward the rear end, and the doors to ether with the step, are set in the inclined p ane of the side lines of the vestibule. Each door is provided at its-upper end with a bracket 14, secured thereto and carrying a flanged roller 15, which is mounted to travel between and upon arallel track bars 16, as best shown in Fig. The top of eachcdoor is also provided with a roller 17, which is adapted to travel on a portion 18 of the track, which extends inwardly at an obtuse angle to the track rail 16. The lower edgeportion of each door is also provided with'the two antifriction guide rollers 19, which are arranged to travel in ways or grooves in the floor of the car step 5, each of these ways or grooves .havinga longitudinal portion 20', and another portion 20 extendin inwardly at an oblique angle to the portion 20 and corresponding tothe portions 18 of the upper tracks. Connected to the outer or closin edge of each door is a link 21, the two links from each pair of doors being connected at their inner ends to a head22, wlnch is, in turn,

connected to a slide 23, mounted on ,the par,- allel slide rods 24. It will beitfn' derstood separates the entrance space or pas downwardly to the from Fig. 1 that one pair of the slide rods 24 is provided for the exit doors and a'similar air for the entrance doors.

e slide. 23 which is connected to the 5 exit doors, is connected by a link 25 with a crank arm 26, on a sprocket wheel 27, which is loosely mounted on the vertical post 9. This sprocket wheel is connected by a chain 28 with another sprocket wheel 29, which is rigidly secured to the vertical rod or post 8.

- This rod or post is journaled at its upper and lower ends to act as a shaft and is provided'with an operating handle 30, within convenient reach of the conductor who stands adjacent to the railing 6. The slide 23 which controls the entrance doors is connected by a link 31 with a crank arm 32, which is rigidly secured to a sleeve 33, loosely mounted on the rod orpost 8, and

which is provided "with an operating handle 34, adjacent to the handle 30, and a so within convenient reach of the conductor. The operation of the doors will be readily understood by reference to the diagram 25 shown in Fig. 9.. In this figure, the exit doors are shown as open in full lines, while the entrance doors are shown in their closed positions, the actuating connections for the respective doors'being also partially shown in their proper positions. Assuming the entrance doors to be closed and that it is desired to open them, the conductor grasps the handle 34, thereby rotating the sleeve 33 on the rod or post 8. This causes the crank 35 arm 32 to actuate the link 31, and thereby the corresponding slide 23. This moves the slide 23 outwardly on the guide rolls 24, and through, the links 21 causes the doors to turn ,on the pivots formed by the rollers 15 and /the correspondin bottom rollers 19. At the same t1me the oors turn on these pivots, the slide backwardly and inwardly on'the r01, er s 17 and corresponding bottom rollers 1,9, on" the angular portions 18 and 20 of the 4,5,,facks or ways, and until they assume the ll open position. This full open position -c responds to the open position shown for t t exit doors in Fig. 1. Inclosing the 'ors, the operation is the reverse, the slide 9 3 being moved back into the position shown n ,Fig. '1. The exit doors are operated in the same manner by means of the handle 30. This movement of the doors causes the 'abhandles 13 to be on the inside of the movement is such in opening and closing asj to encroach but little upon the entrance .and exit spaces or passages. Each painof doors is under the separate and complete control 3 of the conductor, whousually stands within the bent portion 6 of the railing or guard 6, for the purpose of collecting fares.

The connecting link 25 is provided with a bend or offset 35, and the link 31 has a similar bend or offset 36. The bend or ofi'set 35 when the exit doors are closed, in such a manner as to bring the centers of the connections between the wheel 27 and the slide 23, into such relation as to secure the doors in their closed positi us. These centers,

any tendency for them to accidentally move toward their closed positions. The links 21 may also be arranged, as shown, in Fig. 10,

doors whe opened. The bend orofi'set 26 in the link 31 acts in a similar manner with respect to the rod or post 8, as will be seen in Fig. 1.

By the described arrangement of the doors, in which they are made to extend downwardly when in their closed positions to a point ad'acent to the outer edge of'the s'tep, they e ectively prevent access to the step and thus prevent accidents due to perstill in motlon and before the doors have been opened. The door-actuating mechanism is simple and positive in its; character, and enables the conductor to readily control the entrance and exit of passengers. A similar arrangement of doors may be provided at each end of thecar.

It will be obvious that many changes may be made in the details of constrqction and arrangement of the parts. Thus, the doors may be hung and supported in diiferent be changed, air or other power means may be employed instead of hand-operated connections, and various other changes may be made without departing from the spirit and scope of my invention.
