tin-e shaft- 19 ,ofnthis mgtor is'ia worm 20 which mcshes withg 'ivorm wheel-.21 on a. 'vurtlcal shaft 22-hay '1ig lt's bca-rmgs m the jthc. floor 3 of. the vestibule, hcinglslightly plate l4 and. thecz sing 23 located tinder I the filate, as illustrated-in Fig. 4, which in- I chides the clutch mechanism. The plate and the casing are secured to the floor by bolts adapted to recesses in the underside of the worm wheel 21, which is loose on the shaft 29. Tbe' disk 71 is keyed on the shaft so that 'turn with the spindle 31.

while it can slide thereon it must turn therewith Baclr of this disk 71 is a spring 73 which tends to hold the balls in the recesses,-

but should the obstruction prevent the move- Inent of the driven. element then the spring T3 will be compressed and the worm wheel 2f will turn freely on the shaft 22. Secured to the shaftz'ZQ is apinion 27 which meshes with" the gear wheels'28, 29 and 30,-Fig. 3, mounted loosely o'n' spindles 31, 32 and- 33, respectively.- These spindles are connectedto the lever mechanism controlling the several doors. The gear wheel 28 has teeth 34. which 1nesh witl1 teeth 35 on clutch sleeve 36 arranged to slide-on and end,-and on the forks are pins which enter an annular groove n the clutch sleeve 36. The "other end of the lever 31 extends under thetreadleplunger 15 and is recessed for the reccpti on of the plunger, so that, when the plunger 15 isdeprcssed by the foot of the operator, the teeth of the clutch sleeve 36 are forced intome'sh with the teeth 34 on the gear whecl 28; causing the spindle 31 to rotate with the shaft 22.. 011 this spindle 31 isan arm 39 connected by a rod' 40 to an arm 41 on the vertical pivot rod 7 of thecentral-door 6. If the door 6 is in the closed position, as in Fig. 2, by placing a foot on the treadle plunger 15, it throws the parts into gca r and the arm 39 is turned, causing'the said door (2 to swing to the open position, as illustrz zlcd in Fig. 1. If the foot of the operator is not withdrawn from the treadlc ])lllll 2'(1'. the door will swing to the open and then to the closed position, as the arms 31. and 41 are so arranged that while the arm 39 rotates in one direction, the rotation of the arm 40 will merely cause reciprocation.

ln order to lock the door in either the closed or the open position, I form lugs 42 on the casing J3 on each side of the hearing for the spindle 31, as illustrated in Fig. 7. In the underside of the clutch sleeve 36, I form notches 14.23 and bevel the face of the sleeve on one side of each notch, as at 4:4,

.central door.

A lever 37, pivoted'at 38, to the casing, is forked at onebale.

be carried until the notches are directly above the lugs 42, when it willdrop' into' in the slb'eve 36 and rest against a flange 46 .on the spindle 81, Fig. 5, so that as soon as the clutch sleeve is released, the spring will force it awayfrom the wheel 28, so that the plunger 15 is projected into itsnormal p'osition. When the doors are full open or closed f the arm 39 and rod 40. are on a straight line, making, in fact, a double lock for the door. Instead of the .threesprings J shoWn, a v

single spring may be used which willenc rcle the spindle, if found desirableay The wheels 29 and 30 have clutch teeth similar to. the "wheel 28. Thereis' a'clu'tch" sleeve 47 under the wheel 29 and a clutch].

.sleeve 48 under the wheel 30. These sleeves are adapted to turn with and to slideon the" spindles 32 and 33, respectively; :The clutch sleeve 47 is controlled by a-lever49 and the.

clutch sleeve 48 is c0ntrolled by .a le'ver 50 directly underthe p1ungers'16and 17; re-

speetively. The details of these devices are similar to the mechanism for operating-the The? spindle 32has im arm"51' connected- 9' of the door 8, and on pressingthe plunger ;16 the mechanism will be eonnected" so as to close or open the door; ,The spindle 33, in

by arod 52 to an arm 53 on'the' pivot rod.

the present instance, has auar n 54which connected by a rod'55 to an arm 56' on a g rock shaft 57 mounted in bearingsunder the floor of the ear. At the opposite end of this shaft 57 is a long arm 58 which extends into the door channel at the side ofthe car andhas a pin which enters a so'tin a bracket 9 secured to the rear edge of .thedbor 10. This door 10 vhas rollers '66 at'ath'e. upper edge which travel onrarls 61,30 that when the plunger 17 is ,depressdfthe shaft "57 will be rocked and the doorwjll be moved either to the open or the closed position. a;

The doors 6 and 8, in the present instance,

The outer. part of each dooris' hung from a rail (32 by a guidoavhee-l 63;in'the.ordina1y In Fig. 8, I have shown the doors'actuated by solenoid magnets 65. The core of each 7 pair of magnets is connectedto'a door and the mechanism is controlled by two switch boards 66, 67 located at any convenient point within reach of the conductor or other 0perator.

In Fig. 9, I have shown the mechanism in 'are made in two parts eonnected'by hinges.

in Fig. 12.

connects the step with the bracket 68 on the rod 40.

In the event of the motor, or other power driving mechanism, being out of order, the shaft 22 can be turned by hand as it is extended, in thepresent instance as illustrated in Fi 2, to a point near the upper portion of the guardrail and provided with a headto which a handle-can be applied, as

The clutch disk 'i'l'isconnectetl to a rod 74; extending through the shaft, by a pin 75, and the rod is provided with a button 76 at the upper end, so that the operator can immediately press on the button and throw the disk and itsballs out of contaetwith the power driving worm wheel 21, if he sees any one being, caught by the door, and, in order to throw the power driving mechanism. out.

of gear when the mechanism is to be operated manually,'I provide a capped hand lever 77,.Fig'. '12, which is arranged to engage a notched head T8 at theupperend. of the shaft 22 and extends over the button 7 6 and, when the lever is pressed down, a catch 79 engages the head, 78 of the shaft and holds the rod 74 in the depressed position and the clutch out of gear.

In some instances the mechanism may be manually operated during certain hours of the day and power operated during other hours, say the rush hours.

It will be secu by thc above coiistruction,

that I provide an. etl'cctive means for opening and closing the doors of a passenger car. The mechanism is not complicated in construction and is easily actuated by the operator placing one foot on one or more of the trcadles; the hands of the operator being free for the performance of his other duties,

such as collecting fares, etc.

T preferably use the ficadle plunger shown In Fig. (3. havmg two lugs 80 and Sl off set as shtnvn, so that the plunger when passed through a slot in the plate andtu'rned is prcvcntcd from accidentally jumping ut and cannot be mali iously rcmovcd without some tl'ollblc.

ln sonic t vpcs of cars, this mechanism may be controlled by the motorman. instead of by tho comluctor, in, which case his hands would be tree the brake.

\Vhile particularly adapted for use in connection with passenger cars. the device, as stated above. may be used for opening and closing doors in buildil'igs, or may housed in connection with gates which are opened and closed by an attendant.

, While I have shown an electric motor. any other type of. motor may be substituted for to operate the controller and .it. Where the mechanism is located in a building, any suitable power shaft may be geared to it, or the 'main shaft maybe turned by hand, if desired, or where power is not convenient.

When it is desired to Open any one of the doors, the plungers canbe depressed and the 'door operating mechanism clutched to the driven shaft, and onedoor after another can be opened. Itis not necessary to wait until the first door is full open as the mechanism is thrown in action as soon as a treadle is pressed and, after the door commences to move -the operator can take his foot ofi the treadle and the door will automatically stop when fullopened or closed.

While I have shown the treadle plunge'rs I at the floor, so as to be operated by the foot,

it will be understood that they can be raised so as to be operated by one hand of the operator, if found desirable."
