DOOR-OPERATING MEANS.

Divided and this application led August 6,

1913. Serial No. 783,390.

To all 'whom t may concern Be it known that I, GEORGE B. Koi-11,1112, a citizen -of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Door-Operating Means, of which the following is a speci- This invention relates to certain improvements in means for operating the doors of a passenger car, or other vehicle, and is a 'division of an application for patent filed by me o-n the 9th day of April, 1913, under Serial No. 759,981, relating` to door and step operating mechanism.

One objectof the present invention is to provide simple and effective means for opening and closing pivoted doors.

A further object of this invention is to actuate the doors from a vertical shaft through cams which can be adjusted on the shaft.

These objects I attain in the following manner, reference being had to the accompanying drawings, in which:

Figure 1 is a plan view partly in section on the line ca -a, Fig 2; showing the platform of a passanger car party broken away; Fig. 2 is av sectional elevation on the line Z-J), Fig. 1 with the cams in side view; Fig. 3 is an enlarged sectional view illustrating the two cams and their rods; Fig. 4 is a plan view of one of the cams; and Fig. 5 is a detached perspective view illustrating the rod and its connection with the pivot of the door.

Referring to the drawings, 1 is the body of a car.

2 is the platform, in the present instance, and 3, 4 are the doors located at one side of the platform mounted on pivots 5 and 6 respectively. The doors are made in two parts and rods 7 are connected to the outer section of each door and to a fixed point 8 at the roof of the platform so that when the doors are actuated the outer sections will be properly guided into the open or closed position, but the usual upper' rail may be substituted for the bars without departing from the essential features of the invention.

9 is a vertically arranged operating shaft located at about the middle of the platform, in the present instance, and mounted in an upper bearing 10 which is attached to the rail 11 which extends over the platform, and

mounted in a lower bearing 12 located in the floor 13 of the platform. Adjustably secured to the shaft by set screws and located under the floor are two cams 14 and 15 and at the upper end of the shaft is an operating handle 16. Each cam has a single slot therein.

18, 18 are two rods.V One rod extends over the upper cam and the other rod extends under the lower cam. The cams are arranged back to back. Both rods have slotted heads 19 and the shaft 9 extends through the slot in each head and acts as a guide for the inner ends of said rods.

Secured to the lower end of each pivot 5 and 6 is an arm 20. One rod 18 is secured to one arm 20 and the other rod 18 is secured to the other arm 20. The head 19 has a pin 21 which extends 'into the groove in the upper cam 14 and the lower rod has a pin 22 which extends into the groove inthe lower cam so that when the operating shaft is turned the doors are opened or closed.

The cams are so formed, in the present instance, that when the doors are closed the pins are located in the concentric portion of the groove of the cams and when the cams are turned in the direction of the arrow, Fig. 1, the door 3 will be opened first, followed by the other door 4. If the direction of movement of the shaft is reversed then the door 4 will be opened first, followed by the door 3. This construction enables the operator to open either' one of the doors, or both of them, with one operating handle.

By mounting the cams independently on the shaft, I can locate the shaft at any point on the platform or I can pivot the doors at either edge and the cams can be set at the proper position after the shaft is locked.

The invention relates particularly to the means for operating doors and the companion application hereinbefore referred to relates to the means for operating the steps located at one side of the platform below the doors. v

As illustrated in Fig. 2, the step is pivoted at 23 and has a pin 24 which extends through a slot in an arm 25 on an extension of the pivots 5 and 6 of the doors so that as the doors are actuated the steps opposite to said doors will be raised or lowered as the doors are closed or opened.

In the companion application, Serial No.

Patented May 30, 1916.

CIY

broadly the means for operating the engtrance and eXit doors of a car and also, indi this case, the construction in which a single cam is used. The present case is limited to the construction of two cams, one for operating one door and the other for operating the other door.

I claim:

l. The combination of two vertically hung doors arranged side by side; a vertical operating shaft located some distance from the doors; two cams on said shaft; means for adjustably securing each of said cams to the shaft; and means controlled by the cams and connected to .the doors, the cams vbeing so shaped and arranged, on the shaft `that when the shaft is partly turned in one direction one doo-r will be opened, followed by the other door as the movement is continued, and7 when the shaft is turned in the opposite direction, the last mentioned door will -be opened and the first mentioned door will follow.

2. The combination of a Hoor; two doors located above the iioor; a pivot for each of said doors extending under the floor; an arm on each ypivot below the iioor; a vertical operating shaft extending through the floor; two cams on the operating shaft arranged back to back, both cams being located under the floor; two rods having` slotted heads through which the operating shaftextends and by which they are guided; a pin on each slotted head arranged to enter a slot in one of the cams, one rod being connected to an arm on the pivot of one door and the other rod being connected to an arm on the pivot of the other vdoor so that, on turning the shaft, the doors will be opened or closed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
