Application filed. ectober 9, 1909. Serial No. 521,870.
To all whom it may concern: a
. Be it known that I, JAMES S. DOYLE. a citizen of the United States, residing at New York city, borough of The Bronx, in the county and State of New York, have invented certain new and useful Improvements in Door Operating Mechanism, the following being a full, clear, and exact disclosure of the one form of my invention which I at present deem preferable.
For a detailed description of the present form of my invention, reference may be had to the following specification and to the accompanying drawings forming a part thereof, in which- Figure 1 is a diagrammatic illustration of my invention;.lFig. 2 is a front elevation illustrating the practical application thereof; Fig. 3 a diagrammatic view of a modification with the addition of a brake magnet for the screw and also an alternative modification.
My invention involves the operation of car doors in a practical and convenient manner by an electric motor which may be conveniently supplied with current from the operating trolley line. I
Turning to Fig. 1,- A represents in dotted lines the car door, and B an operating electric motor the connectionof which with the door will be hereinafter described.
C represents an ordinary circuit-closingand-reversing switch, which will be subject to the hand control of the operator. The current, after passing through said switch, will be delivered to'th e motor, in the event of its being mounted on the door, as pro,- vided for in one form of my invention, by means of sliding contacts 1, 2, 3, and 4: traveling on stationary contact rods adjacent tothe door; or the motor may be connected with the switch by means of flexible conductors in a way well known to the art.
D is an automatic switch located in that circuit produced by controlling switch C which may be termed the opening-circuit, for operating the motor in, the direction to open, the door. The switch D is shown as of the lever form, normally heldflclosed by a spring, and having a projection on the lever standing in the path of thedoor so as to be struck thereby when the door reaches the limit of its opening run. By this means I Specification of Letters Patent.

the switch D automatically. opens the motor circuit and stops the motor after the door has been opened.
In addition to the electrical operation above described, I also provide means by which the motor circuit will be automatically broken in event of the door encountering some obstruction while moving to its closing position. This device includes an obstruction-strip a on the front edge of the door pivoted at its lower end and normally held outward by a spring a but limited in its forward play by a stop a The upper end of the strip a is forked to embrace one branch of the angle lever a having a pawl on the other branch adapted to engage with a a rack a whenever the strip a may be pressed 4 in by its contact with some obstruction during the closing operation of the door. The rack-bar a is suspended from parallel links, one of which is also an angle lever carrying the switch arm a controlling the switch a. It is normally drawn toward the left by a spring, and in the event of the pawl being thrown into engagement with the rack, as just described, the rack is drawn forward by the continued movement of the door against the force of its retracting spring, and the switch-lever a. thereby operated to open the motor circuit and stop the motor. It is not necessary to trace the motor cirv cuits, it being manifest to an electrician that the motor is of the simple series type controlled by the switch 0 to stop, start and reverse it. f
C is an ordinary circuit closing and reversing switch of the drum or rotary type having two sets of contacts 10, 11, either one of which may be brought into engagement with the contacts Z connected with the five circuit wires 00, w, :0 m m. This switch is diagrammatically illustrated in Fig. 1. As-
suming the door to be closed and the switch operated to bring the wires in connectlon with the contacts 11. The circuit is then from the trolley wire through wire a: to
TSWltCll D, the latter being closed when the 190 door is shut. From switch D the current passes to contact 2 and from thence through the field of the motor to contact I, from thence through wire as, switch c, wire (1: to
contact 3, thence through the motor tocontact 4 and finally to ground. When the door reaches the open position the switch D is automatically operated to break the circuit and switch blade at is brought into engagement with its contacts. Therefore it is necessary to operate switch a to cause current to pass through switch a before the motor may be operated to close the door. When it is desired to close the door the switch is moved to connect the wires with contacts 10. The current then passes through wire a," to contact 1, and from thence through the field of the motor to condoor is closed and it will be necessary to rotate switch 0' to cause the current to pass through switch D before the motor may be again operated.
Turning to Fig. 2, the door-motor B aforesaid is shown mounted on the door A near the upper edge and provided with a hollow armature shaft carrying a nut en gaging the threads on a long screw E mounted on the outside of the car above the door and outside of the suspension rollers a by which the door travels on an overlying track. The rotation of the armature in one direction or the other, under the control above described, will cause the motor and the door connected therewith to travel back and forth to open or closed position following the screw Turning to Fig. 3, the motor B is fixed to the sidewall of the car and drives the screw E upon which are nuts 6 attached to the door. In this case the rotation of the screw will drive the door in one direction or the other. In this figure I also show -a magnet F adapted to be energized by means of the aforesaid switch arm a", which comes in operation as heretofore described when the door encounters an obstruction. The switch arm a not only opens the motor circuit .but also closes a shunt circuit through-the magnet F, which is thereby drawn into contact with the brake disk 6 electric motor, an automatically acting emergency switch in circuit with said motor, a screw and nut connection between the motor and the door to positively move the latter in either direction, and means carried by-said door for controlling said emergency switch.
2. The combination with a door, of an electric motor, an operating connection between the motor and the door, a movable obstruction strip attached to one edge of the door, a switch in the motor circuit and sup ported independently of the door, and a switch operating lever carried by the door, said lever being located on the same edge of the door as the obstruction strip, and provided with a portion interengaging with one end of said obstruction strip.
3. The combination with a door, of an electric motor for operating the same, a pivotally suspended controlling device for said motor extending along the route traveled by said door, a circuit including the motor and the controlling device, a movable ob-.
struction strip attached to one edge of said door, and a lever carried by said door to actuate said controlling device, said lever being located on the same edge of the door as said obstruction strip, and provided with a portion interengaging with one end of said obstruction strip.
4. The combination with a door, of an electric motor for operating the same, a controlling device for said motor, a pivotally suspended operating rack for said controlling device, a circuit including the motor and the controlling device, a pawl carried by said door near one edge thereof and adapted to engage said rack, and a movable obstruction strip attached to same edge-of the door as said pawl and interengaged therewith.
5. The combination witha door, of an electric motor, an operating connection between the motor and the door, a movable obstruction strip attached to one edge of the door, a switch in the motor circuit and supported independently of the door, a switch operating lever carried by the door, said lever being located on the same edge of the door as the obstruction strip, and provlded with a portion interengaging with one end of said obstruction strip, and a reversing controller for the motor.
6/ The combination with a door, of an op erating electric motor therefor mounted on the door, a stationary screw parallel to the route of the door, a nut on the screw operated by the motor, means actuated by the door for automatically breaking the cmcuit to the motor at either limit of the movea screw and nut connection betweenthe m0- meteor will;
