Original application filed September l, 1908, Serial No. 451,161. Divided and this application filed December Serial No: 466,621. A

To all whom it 'may concern.'

Be it. known that I, FRANCIS X. MALoesAY, a citizen o1 the United States, and a resident of Jersey City, county 'ot Hudson, State oi' New Jersey, have invented certain new and useful Improvements in Gar- Doors, of which the following is a specification.

rl`his application is a division of my former application filed September 1st, 1908, Ser. No. 451,161.

The object of my invention is to provide a ycar of this class in which the doors are so arranged that at the rear end of the car, the regular entrance door will operate so as to permitpassengers to enter the car, but. not to leave the car, and the doors at the other end will permit the passengers to 'leave the car, and when the car runs in the opposite direction, the -doors canbeniade to operate in the reverse manner, that is, the rear door which was the front door, will operate so as to admit passengers and the other door will operate so as to permit the egress of passengers.

For a more particular description ot' my invention, reference is to be had to the ac companying drawings, forming a part here.- ot in which: I

Figure 1 is a sectional plan view showing the door closed. Fig. 2 is a similar view showing the door in the position it occupies when used for egress purposes. Fig. 3 is a plan view of the structure above the door. Fig. 4 is ay detail view. Fig. 5 is a view similar to Fig. 1 except that the door is shown in the position it occupies immediately before a passenger' enters the car.

Throughout the various views ot the drawings, similar reference characters designate similar parts.

In this embodiment of my invention the partition 127 and the door sill 131 and the posts or uprights 129 and 130 are the same as in the modifications shown and described in my said application tiled Sept. 1, 1908, Ser. No. 451,161, but the door 3 is peculiar and operates in a different manner.

rFhe partition 127 is connected to the rear wall of the car by a ceiling 132 which has a slot 133 which divides the ceiling in two Vvparts 134 and 135. Part 135 .is supported from the art 134 by braces 136 which are raised sul ciently above the ceiling 132 as to be clear of the slot or cam groove 133 andv Specification of Letters Patent. i i

is inade substantially with three arcs of eircles, or nearly circles Joined by curves at the corners. For convenience these arcs may be designated 137, 133, 139. The arc 139 is widened at 140 for a purpose that will appear below. Except for this widening the groove 133 is of the same width throughout. The loor 17 is also provided with a cam groove 141 which is identical in form with the cam groove 133 and immediately under the saine. The door 3 is a plane door with pintles 142 at its top and bottom, running vertically and adjacent to the corners. These pintles 142 move in the cam grooves 133 and 141 respectively. The door 3 is also provided with two projecting handles 143 located as shown, by means of which this door may be operated. If the door 3 is to be opened when in the position shown in Fig. 1, the exterior handle 143 is shoved which causes the side of the door having a pintle `in the enlargement 140 to turn on this pintle as a pivot and the door opens as an ordinary door unt-il the position shown in Fig. is reached. The person entering then stands on the Hoor 17 between the partition 127 and sill 131 and still grasping the handle 143 shoves it to the right thereby shifting the door 3 with an edgewis'e and turning motion whereby it slides to the position indicated in Fig. 1 except that the handle 143 which was the exterior handle, is now the interior hanbolt 144 moving between suitable guides 145` and provided with a suitable head 146 in which is a cam groove which is so arranged and disposed that the edge of the door next the'upright 130 can move toward thevupright r129, but cannot move in the reverse direction. The ceiling 132 and the floor 17 are also connected by a' pivot plank 147 which is adapted to engage spring-'pressed bolts- 148 so as to be held as shown in Fig. 1, or as in Fig. 2. This pivot board has at its top and bottom, projections 149 adapted to engage the pintles 142 at the top and bottom of the door 3 and this board also has a spring-pressed hinge 150 which rests against the door 3, but is not otherwise connected with the saine. The pivot board 147 has a projection 151 through 'the ceiling 132 on which is tilted a crank 152 which isconnected with the bolt 1441s by a. suitable link 153 so that when the pivot board 147 is thrown to the position indicated in Fig. 2., the bolt 144, is so shifted as to form a positive stop to limit the swinging oLt the door 3 farther th-an shown in Fig. a. This is used when the door 3 is used as an exit door. In such use the door 3 is thrown as shown in Fig, 2, the pivot board let? then being used, and the door is normally keptgclosed by the spring hinge 150. lt is opened against the pressure oit this hinge, the pintles lst-2 at one edge ot the door turning in the projections 149, and the pivots 'blt2 at the other edge oi` the door sliding in the groove iinn'iediately below the saine so that by sliding the handle 143 next the upright 13() the door may be used as an ordinary swinging door.

While I have shown and described one embodiment of my invention, it is evident that it is not restricted thereto, but is broad enough to cover all structures that come Within the scope of the annexed claims.

Vhat I claim is:

l. In a car of the class described, a fixed partition and posts all held parallel to each other, a door and means for mounting said door so that it will either slide or swing between said posts and said partition.

2. In a car of the class described, a fixed partition and posts all held in parallel relation to each other, cam grooves running from said partition to said posts and located in the Hoor and ceiling of said car, a door having pintles adapted to move in said grooves and means for mounting said door so that it swings from definite parts of said grooves, as desired.

3. In a car of the class described, a partition and posts h'eld in parallel relation to each other, a partition and a ceiling connecting these parts, a cam groove in said ceiling and in said partition, a door having pintles moving in said cam groove and means eX- tending adjacent to said grooves for receiving and securing one pair of pintles so that these pintles will act as a pivot on whichthe door may turn.

It. In a car of the, class described, a partition and a pair of posts held in parallel relation, a ceiling and a floor uniting said posts and partition, cam grooves in said ceiling, a door with pintles engaging said groove whereby said door may be shifted bysliding from a position between said posts to one between said posts and said partition, a pivot board mounted in said floor and ceiling and means for pivotally connecting said pivot board and one pair of pintles on said door whereby the said door may be swung on the parts attached to said pivot board.

In a car ot' the class described, a partition and a pair of posts adjacent thereto and all held in fixed relation, aceiling and a lfloor secured to said posts and said parti tion, cam grooves in said floor and ceiling, a door and pintles on said door engaging said c am grooves so that it may be slid lrom one position to another and means for preventing said door from sliding in one direction.

(3. ln a car of the class described, a ceiling and means for supporting the same, a tloor running parallel to said ceiling, a pivot board connecting said iloor and ceiling, a door with pintles entering said grooves, a bolt adapted to slide trai'isverselyof 011e of said grooves and above the same, and means'- com'iecting said bolt with said pivot board whereby said bolt is shifted to act as a stop to prevent said door from having more than a predetermined amountlof swing.

Signed at the city, county and State otV New York, this 26th day of `November, 1908.
