PASSENGER-CAR.

Specification of Letters Patent.

Patented Sept. 14, i909.

To all whom it may concern:

Be it known that we, SAMUEL M. CURWEN and WARREN M. SMITH, citizens of the United States, residing in Haverford, Pennsylvania, and Moores, Pennsylvania, respectively, have invented certain Improvements in Passenger-Cars, of which the following is a specification.

Our invention relates to certain improvements in passenger cars of the type in which a door is provided at one or both sides of the platform.

The object of our invention is to provide means for closing the space between the bottom of the door and the floor of the platform without cutting away the sills of the car.

Our invention can be applied to any type of car having a platform and in the drawings we have shown our invention as applied to the ordinary type of electric passenger car. l

In the accompanying drawings z-Figure 1, is a sectional plan view of one end of a passenger car illustrating our invention;

the door on one side of the platform being open and the door on the other side being closed; Fig. 2, is a longitudinal sectional view on the line 2-2, Fig. 1; Fig. 3, is a transverse sectional view on the line 3-3, Fig. l; and Fig. 4, is a transverse section on the line 4,4, Fig. l.

A is the body of the car.

B is the platform.

C is the transverse partition separating the body of the car from the platform and having the usual doorway c.

B is the vestibule casing inclosing the front of the car. On each side of the platform are doors D, D adapted to slide in ways in the car body. rIhe doors pass through slots c in the partition C and can be separated from the interior of the body of the car by any suitable partition, or they can be exposed, as desired. The doors are mounted so as to clear the sill A of the car body, thus the sill is not weakened by placing the doors at the side.

The floor of the platform is usually below the floor of the car and consequently in order to entirely close the side of the platform with a single door the sill A must be cut away sutliciently to allow the bottom of the door t0 be on a line with the floor of the platform, if the sill is not cut away the bottom of the door will be in linevwith the floor of the car body and consequently when the door is closed there is an opening between the bottom of the door and the platform support.

he object of our present invention is to rinclose the space between the door and the platform without cutting away the transverse sill A or in any way weakening the construction of the car body.

le mount on each side of the platform sliding doors E, E. These sliding doors are adapted to ways in the platform and are arranged to move vertically in and out of position. When in the raised position theyl abut against the underside of the doors D, D when closed, and when in the open position are below the platform, so as not to interfere with passengers alighting from or boarding the car.

In the present instance we actuate the doors E, E from the doors D, D and we so time the mechanism that the doors E, E will not be elevated until the doors D, D are partially closed, so as not to trip any passenger endeavoring to board or leave the car when the doors are partially open.

ln the present instance the mechanisms for operating the doors are identical and we will describe the mechanism in reference to the doors D and E. On one side of the door D near the rear is a rack cl which engages with a pinion f on a vertical shaft F and this shaft extends through the framing of the car body and has at its lower end a bevel wheel j which meshes with a bevel wheel g on a longitudinal shaft G adapted to bearings in the framework of the car. Near each end of the shaft Gr are pinions g', which mesh with vertically arranged racks c, c secured to the back of the door E. By this arrangement as the door D is closed the rack l comes in contact with the pinion f on the vertical shaft F and this vertical shaft is turned and motion is imparted to the bevel gears on the shaft G, and as this shaft is geared to the door E the door will be raised as the door D is closed; the parts being so timed that the upper side of the door E will contact with the lower edge of the door D.

On the first movement of the door D the door E will be withdrawn so that it will be clear lof the platform before the doorD can be opened suiiciently to allow a `passenger to get on or off the car.

By the above described arrangement, we

are enabled to completely inclose the plat-` form without cutting away or weakening the frame of the car body and without placing the door on the outside of the car body.

7e clainu* l. The combination in a car body, of a platform, a transverse partition separating the platform from the channel in the partition, a sliding door mounted above the sill of the car and eX- tending through the channel and adapted to extend over the platform, with a vertically arranged supplemental door at one edge of the platform, and gearing ,between the sliding door and the supplemental Ydoor whereby on the movement of the sliding door the supplemental door will be actuated.

2. The combination in 'a passenger car, of a platform, a sliding door adaptedV to close one side of the platform, a vertically ar-Y ranged supplemental door at the side of the platform, a rack on the sliding door, avertical shaft having a .pinion thereon meshing with the rack, a rack on the supplemental door, a shaft, a with the said rack, and gearing between the close one side body of the car, aY

pinion on the shaft meshing by Y of the floor ofthe bodyl portion, said floor lof a channel in the framework of theV Y rear of the door, a vertical shaft having a j Vpinion arranged to mesh with the'raclr when the door is partlyY opened,- a vertically `ar"- ranged supplemental door at the edge of the platform, a rack on said door, a horizontal shaft, a pinion thereon meshing with theV rack, and gearing by'which theV horizontal shaft is driven from the vertical shaft, the 'Y Y parts being so arranged that the slidingV door will be partly kclosed before the supplemental door will be elevated. ,Y

In testimony whereof, we havefsigned our e names to this specification, in the presence of two subscribing witnesses. 1
