Specification of Letters Patent.

Application filed July 28, 1910. Serial No. 574,337.

T 0 all whom it may concern:

Be it known that I, WILLIAM H. GROVE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Means for Operating the Doors and Steps of- Passenger-Oars, of which the following is a specification.

The object of this invention is to provide means for operating pivoted doors at the side of plat-forms of passenger cars or other vehicles and to simultaneously move the steps into and out of position.

lVhile my invention is -'particularly adapted for use in operating doors at the platforms of passenger cars, it will be understood that it may be used for actuating doors for other purposes without departing from the essential features of the invention.

Furthermore, the door operating mechanism may be used either with or without the step mechanism.

In the accompanying drawings :Figure 1, is a sectional plan view of a passenger car illustrating the doors at one side ofthe platform; the doors being in a closed position; Fig. 2,v is a view similar to Fig. 1, but taken on the line at the top of the platform, showing the doors closed; Fig. 3, is a view similar to Fig. 2, showing the doors open; Fig. 4, is a sectional view on the line 44, Fig. 8; Fig. 5, is a side elevation of the platform, showing the steps raised out of position and the doors closed; Fig. 6, is a view illustrating a modification of the step actuating mechanism; and Figs. 7 and 8', are

.views of modifications illustrating my invention when the doors are used with .a fixed step.

A is the platform of a car.

B is the door frame and B is the central post of the frame.

O, O and D, D are the doors; one pair of doors being between one post and one side of the frame and the other being between the center post and the other side of the frame. In the present instance D, D are the doors closing the ingress passageway and O, O are the doors closing the egress passageway. The doors are hinged at d,d

and 0, 0 respectively, and are arranged to open outward as indicated in Fig. 3.

E is a vertical shaft-mounted in a suitable tube E and extending from the floor of the platform to the roof thereof. On the upper portion of the shaft is a tubular shaft.

v E On the shaft E is a hand lever 13 and on the tubular shaft E is a hand lever 6; At

the upperend of the shaft E is an arm 6* connected by a link K to one of the doors Dv at f, the .link being open to allow it to extend around the shaft E when the door is in a elosedposition, as in F ig. 2. On the door D is a bracket 9 which extends inward, as shown in Fig. 2, and connectin this bracket witht-he door D is a link (I which is bent at right angles where it joins the door D. By this construction when the operating lever e is turned it turns the shaft E and forces the door D open, and, as the door opens, the door D will follow, as the doors are connected by the link G. The doors will then assume the position illus trated in Fig. 3. I

The tubular shaftE has an arm 6 connected by a rod F to the door O and the door O has a bracket g connected by a link G to'the door- O; this construction being similar to the link construction of the doors D, D, so that when the tubular shaft E is turned the doors O, C will be opened or closed. The operating levers e, 6 also act as guards when moved in the two positions so as to separate the passengers entering and leaving the car. Fixed rails on the platforms may also be used' if found necessary, and these rails may be shaped in any manner desired.

Onthe pivot d of the door D is a sprocket wheel 2' and on a shaft I on the underside of the platform is a sprocket wheel 2". Extending from one sprocket wheel to the other is a chain 2' On the end of the shaft I is a lever K connected to the arm 70, which is in turn connected to a projection 70 on the underside of'the step K. This step is pivoted to a bracket m on hangers M secured to the platform of the car. When the door is opened motion will be imparted through the chain 1 to the shaft I and will lower the step to the position illustrated in Fig. 4. Whenthe door is closed the step will be turned on its pivot out of operative position.

The step K opposite the ingress passageway is operated from the door C. in substantially the same manner as the step K, and the shaft I has an arm /a connected by a link is to a projection 70 on the step K. In place of the sprocket chain, the shafts I may be connected by rods 2' attached to arms, as clearly shown in Fig. 6, without de- 'will be'i1 weredor ra sed. v
