Application filed January 2, 1908.

To all whom it may concern:

Be it known that I, JOSEPH B. STRAUSS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Cars, of which the following is a specification.

This invention relates to improvements in cars, and has for its object to provide a new and improved door and step therefor.

The invention is illustrated, in the accompanying drawings, wherein Figure 1 is an inside plan view of the car vestibule; Fig. 2 is a sectional view taken on line 22 of Fig. 1; Fig. 3, is a sectional view taken on line 3-3 of Fig. 1, with parts omitted.

Like letters refer to like parts throughout the several figures.

Thevestibule is provided with a floor 1 and the walls 2, and there are provided suitable doors to permit passengers to pass to and from the car. There is preferably a I door on each side of thevestibule and a Step arranged at the door, the step and door adapted to be simultaneously operated. In

divided into sections so that when open it will occupy only a small space. As herein shown, the vestibule door is made up of two sections 3 and l. Section 3 of the door is mounted upon the frames 5 at the top and bottom, and the section 4, upon the frames 6. These frames are horizontal and are mounted upon suitable pivots so as to be moved about such pivots. As herein shown, the frames are mounted upon the vertical shafts 7. The frames 5 and 6 at the bottom are provided with suitable supports beneath the vestibule floor. These frames are provided with tracks 9 which are engaged by rollers 10 fastened to the frames. The doors are received into the portion 11 of the vestibule wall when open, so asto be out of the way. When the door is made into sections the two frames 5 and 6'may be used, but if the door is only in one section one frame may be omitted. When'the door is made in sections the sections are spread apart when the door is closed and are brought together whenthe door isopen, as shown in Fig. 1, the two parts collapsing in any desired manner. It will be seen that by rotating the Specification of Letters Patent.

shaft 7 these doors may be easily and quickly opened and closed and the two sections collapsed when opened so as to occupy only a small space. Some suitable arrangement is also provided for moving the steps 12 to their operative and inoperative positions. Both the step and the door are preferably operated from the same device or shaft 7.

As herein shown, the frame 5 is provided with a rack 13 which engages a gear 1 1 on a shaft 15. This shaft has a beveled gear 16 which engages the beveled gear 17 on a shaft 18 to which the step 12 is fastened. The parts are arranged so that the step is moved to its operative position when the door is opened and to its inoperative position when the door is closed. The shaft 7 may be operated in any desired manner, as by means of a folding handle 19. When the car is in motion the doors are closed so as to completely inclose the vestibule, and the steps are in their inoperative position so that passengers cannot stand thereon. When the car is stopped the conductor rotates one of the shafts 7 thus moving the frames 5 and 6 about their pivotal points. The door is then slid open and the two sections collapsed so as to form a wide opening for the entrance and exit of the passengers. When the rack 13 engages the beveled gear let the shaft 15 is rotated and also the shaft 18, thus moving the steps 12 into their operative position so that the passengers can use them. The steps are held in this position as long as the doors are open. When it is desired to start the car, the conductor rotates the shaft 7 in the opposite direction. This moves the frames 5 and 6 back to their initial position, moves the two sections of the door with relation to each other, and closes the door opening. The movement of the rack 13 to the connection to the shaft 18 causes the steps, during this operation, to be moved to their inoperative position. The steps may be counterweighted if desired to facilitate their movement.

It is, of course, evident that the construction may be varied in many particulars and for purposes .of illustration I have shown.

ment about the pivotal point outside of such sections, the sections forming the arc of a circle and moving in the arc of a circle.

I claim:

1. The combination with a vestibule for cars, having an opening through which'passengers pass, of a swinging section having a rotary movement about apivotal point outside of said section and located at the edge of the vestibule, said swinging section and pivotal point being on opposite sides of the center lineof the car, and a sector extending between the pivotal point and said swinging section.

2. The combination with a vestibule for cars of a swinging section extending from the top to the bottom of said vestibule having a rotary movement about a pivotal point at one side of such section, and a movable step connected? with said section and adapted to be moved to an inoperative position when the section is moved to its closed position.

3. The combination with a vestibule of a swinging section extending from thetop to the bottom of said vestibule, a substantially horizontalradial member connected at one end to said section and movably connectedat the other end to afiXed part formed in the arc ofa circle, and means for moving said section in the arc of a circle to open or close the vestibule, said horizontal radial member extending across said vestibule, the fixed part to which it is' attached being at one side of the vestibule, the opposite ends of said radial member being on opposite sides of the centerline of the car. I

4:. The combination with a vestibule of a swinging section, a substantially horizontal radial member connected at one end to said section and movably connected at the other end to a fixed part formed in the arc of a circle, means for moving said section in the arc of a circle to open or close the vestibule, and a step associated with said section, the position of which is controlled by the movement of said section.

5. A vestibule for cars comprising a swinging section, a plurality of supporting devices at the bottom of said section and located beneath the car platform, said section projecting below the platform of the car at the point where the supporting devices are connected thereto, said supporting devices adapted to be moved with relation to each other as the swinging section is opened and closed. I i
