j which the" following is a specification.

. The object of my invention is to provide means for operating the side doors of the a platform of a'passeng r car -which will be clear of thetpassageways leading to and from the body of the car and yet willbe eX- posed so that in the event ofrepairs access may be readily had to the apparatus.

in the accompanying drawings:- Figure trating my invention; Fig. 2, is a plan view owing the doors in the open position; Fig. 3, is a plan view showing the doors in a closed position; Fig. 4t, is a vertical seotional view through the operating device,

and Fig. 5, is a detached perspectiveview of the device illustrating a. detail of the invention. i I

A. is the body of the car.

B is the platform having the usual front.

vestibule casing B and G is the roof of the platform. In the present instance the platform isopen at one side and this side is closed by a pair of double doors D and E.

- Both doors may swing outward, as indicated pin 9 and to the arm d inFig. 2, of the drawing. The doors are pivoted at cZ and 6 respectively, and these pivots are in tllefOrlll of rods which extend, in the present instance, the full height of the door, and at theupper end of these rods are arms (Z and e.

F is a bearing secured to the plate F and attached to the roof of the car. Mounted in this hearing is a vertical shaft G carrying the rope sheave g at its lower end. upper end of the shaft is a head 9, which rests upon the bearing. and in the present instance there is a ball bearing a mounted between this head and the bearing. rope 72, passes around'this rope sheave and on each end of the rope is a hand hold. The ropes passing around the grooved guide rollers 7o, mounted in bearings ,f, in the present instance, independent of the bearing F. Projecting from the under side of the sheave are two pins g 9 to which rods n, n are attached-one rod 7 being attached to one on the pivot rod cl,

while the other rod 72 is attached to the noonornaarme resentment.

pin 9' and to the arm 0- onthe pivot rod 6 sothat when the sheave 1s rotated-first in onedirection, the doors will be opened, and

when rotated in the opposite direction, the doors will be closed.

The rods n, a. are so formed that the pins can pass the'center line drawn through the pivot of the arms and through the shaft, thus locking the doors in the closed positionf Projecting from the bearing F is a stop and on the sheave g are lugs m. One ofthese lugs contacts with. the stop when the sheave is turned in one direction and the other lug contacts with the stop when moved in the opp.site direction. lvr'lounted in the stop in the present instance are cushions of rubber or otl er yielding material. Mounted on an extension 2) of the shaft G is a cup or shield P, which is arranged to catch any oil that may drip from the bearings.

The. doors are made in two sections and the doors open outward, in the present instance. The sections D and E are mounted on the pivots (Z and a, while the sections D and E are pivoted respectively to the outer ends of the sections D and E and fold inward. Onthese sections D and E are pins or rollers (Z and 6 which travel in an overhead guide rail C at the roof of the car. The lower ends of the doors may also be provided with rollers, which travel in guideways, but this is not absolutely essential.

The operation of the mechanism is as follows :'VVhen the doors are open, the hand holds are in the position illustrated in Fig. l, and the conductor is located on the platform in close proximity to the hand holds and by simply pulling down on the one which is the highest the sheave is turned and the doors are moved to the closed position and preferably locked automatically. Vhen it is necessary to open the doors, the other end of the rope is pulled down, causing the sheave to turn in the opposite direction, and the doors are thus moved to the open position.

All of the mechanism, with the exception of the two depending ends of the rope, is

above the head line of the car platform, and

the ropes are located in close proximity to cJi the passengers entering or leaving the car.

The combination in means for operating passenger car do0rs,-of an overhead bearing, a vertical shaft in the said bearing having a head resting on the bearing, and a sheave secured to the shaft under the bearing, pins on the sheave to which the rods are attached leading to the doors to be operated, a stop on the bearing, and lugs on the sheave contacting With the stop to limitthe movement of the sheave, and means for rotating said sheave to operate the doors.
