CANADA .A'UTOMATIC'DOOR, WINDQW,- OR GATE OPERATING DEVICE Application filed. December 20, 1930. sen-n No. 503,331.

This invention relates to new and-useful improvementsin operatingdevices for sliding doors, windows, gates, etc.,and has for the primary object, the provision of a combined electrical and mechanical operating means having a' remote control, whereby a person may easily. and quickly a'ctuate='the.

same to cause the opening or closingof the door, window or gate as desired.

Another object of this invention is the pro vision of an automatic means for stopping the operating means when the door, window or gate actuated by the operating means reaches a closed or open position. I

A further object of this invention is the provision of an operating device for sliding doors, windows, gates, etc,, of the above stated character, which will besimp-le, durable and efficient, and which may be manufactured and sold at acomparatively low cost. i

With these and other objects in View as Will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, referenceis to be had to the following description and accompanying drawings in which: V

My invention is applicable to sliding closures such as doors, windows, gates, etc., and

to give a clearundersta nding as to the con struction and operation of my device, I have elected to door.

' A'door frame 1 has associated therewith a sliding door 2 mounted for opening and closing the doorway by a sliding movement and is mounted in any conventional manner. Supporting brackets 3 are secured to the door frame 1 and'are providedwithbearings 4 to rotatably support an operating shaft 5 which has formed'thereonrightand left hand feed grooves 6 and as shown in Figure 1, the shaft 5 may be of any desired length for the purpose of operating a number of show the same applied to a sliding doors and the operating means for such doors are identical in construction, therefore reference to one is thoughtsuificient for all. The rlght and left hand feed grooves 6 intersect each other as clearly shownin Figure 1 and terminate at each end where the grooves in-' tersect with each other.

- A conventional type of over running clutch 7 is secured to the shaft 5 and has connected thereto a gear 8 meshingwith a worm gear 9 fixed to a shaftlO ,jour'naled. in suitable brackets 11 carried by the door frame. 1. An electric motor 12is supportedby the door frame 1 and the drive sha'ftl3 thereof carrise a worm gear 14 which meshes with a gear 15 secured to the shaft 10 whereby the shaft 5 may berotated in one direction by the motor12. i I p I j A housing 16 is secured to the door 2 by a bracket 17 and slidably receives the shaft 5 .and has journaled therein annular actuating members 18 provided with lugs or projections 19 received by the feed grooves 6 of the shaft 5 and said lugs areof such size so that they will bridge an intersection of the grooves and thereby always travel in their respective grooves; The actuating members 18 surround the shaft 5and have formed on their outer edges flanges 20 provided with teeth 21 and the teeth of one of the actuatingmembers y 18 are to be engaged by teeth 22 on a reversing'member 23 when the latter is in oneposition and. when in another position the teeth 22thereof are adapted to engage 'theteeth 21 direction. opposite direction engages the teeth 22 of of the other actuating member 18 for reversing the movement of the door. The reversing member 23 is of annular formation mounted upon the actuating members 18 and held against rotation therewith by the forked arm 24 of a shifting lever '25 having a universal mounting with the housing 16 as shown at 26. Theforlred arms 24 have pin and slot connections with the reversing mem ber 23 as clearly shown in Figure 6. The reversing member 2.3 has a. neutral position as shown in Figure 6 and the movement of the lever in one direction engages the teeth 22 with the teeth 21 of one ofthe actuating members 18 locking said member 18 against rotation and as the lug 19 thereof engages in one of the feed grooves'6, the rotation of the shaft 5 will cause the door to slide in one A. movement of the lever 25 in an the reversing member 23 with the teeth 21 of the other actuating member 18 and owing to the lug 19 thereof being in engagement with the other feed groove of the shaft 5 will cause the door to slide in a reverse direction. Stops 26 are carried by the door frame 1 and located adjacent the limit of movement of the door 2 in either direction for operating the shifting lever 25 and the later is of a construction to give the reversing member 23 a snap action when engaged by one of the stops. It is to be understood that when the shifting lever 25 engages one of the stops 26 .the reversing member 23 is in mesh with one of the actuating members 18 and during the movement of the lever 25 the actuating member is moved out of engagement with said actuating member 18 and into engagement with the other actuating member 18 placing the reversing mechanism in proper position to move'the door in an opposite direction on further rotation of the shaft 5.

Circuit interrupters 27 are located on the door frame 1 and are actuated by trips 28 carried by the door and the trips are of identical construction except they are mounted on the door reverse to each other so that the movement of the door in one direction,

. one of the trips actuates one of the circuit 'interrupters and on a reverse movement-of the door said trip 28 passes the respective circuit interrupter without operating the same. This applies to the other trip and respective circuit interrupter when the door moves in a reverse direction. Reference to one of the trips 28 specifically is thought to answer for both. The trip includes a pivotally mounted plate 29 carrying a curved arm 30 normally urged into engagement with a lug 31 on the door by a tension spring 32. A dog 331's pivoted to the plate 29 and is limited in movement in one direction by a Lug 34 onthe plate 29 and is normally urged in engagement with said lug 34 by a tension spring 35. The dog 33 in engagement with the respective interrupter without actuating the same. The dog 33 during the reverse movement of the door will swing upon its pivot when engaged by the stop without moving the arm 30 of the trip 28 into an active position. i

An electrical source including positive and negative electrical feed lines 37 and 38 are provided and theelectric motor 1-2 has one pole thereof connected to the positive feed line 37 by a conductor 39 while the negative conductor 38 is connected to onerof the interrupters 27 and said interrupter is connected to the other interrupter 27 by a conductor 40. The last named interrupter is connected to a contact 41 of a magnetic switch 42 by the conductor 43'. The magnetic.

switch 42 includes a double solenoid 44 which has the core 45 thereof-associated with a pivoted circuitclosing arm 46 norm-ally held disengaged from the contacts 47 and 41 by a spring 48. A conductor 49 is connected to the other pole of the electric motor 12 and to one of the windings of the double solenoid 44 and said winding is connected to the contact 47 by a conductor 50. The other winding of the double solenoid 44 is connected to conductors 51 and 52 and the conductor 52 is connected to the positive feed conductor 37 while the conduct-or 51 is connected to switches 53 and the latter are of any suitable type preferably of the push type and are electrically connected to the negative feed conductor 38 by a conductor 54. It is to be understood that the switches 53 may be located at any desired point relative to the door or the building and convenient for the operation of the device.

In operation, when desiring to move the door in one direction, or into a position opposite to that now occupied, a person pushes one of the switches 53 completing an electric circuit to one of the windings of the double solenoid 44 which attracts the arm 46 and bridges the contacts 41 and 47 completing the circuit to the electric motor which immediately energizes the other winding of the solenoid maintaining the arm 46 in engagement with the contacts 41 and 47. The motor now in operation rotates the shaft 5 causing the door to-slide towards a position opposite to the present occupied position and as the door reaches the limit of its movement, the stop 26 actuates the shifting 1e ver 25 re-setting the reversing member 23 and simultaneously one of the trips 28 is positioned to actuate one of the interrupters 27 breaking the circuit to the motor and stopping the rotation of the shaft 5 and consequently the movement of the door. The interrupters are of a type that they will auto matically resume an operative or circuit closing position when disengaged from the trip 8 and only occupy a circuit breaking position sufliciently long to break the circuit to the motor 12, it being understood that when the circuit to the motor 12 is broken.

the arm 46 disengages from the contacts 41 and 47. The device is nowpositioned ready for operation to move the door in a reverse direction and a person presses upon one of the switches 53 again setting the motor in operation and the door moves in'the reverse direction in the manner describedwith reference to its movement in the first direction.

Cushion springs 55 are mounted on the shaft 5 adjacent the 'ends thereof and are adapted to cushion the movement of the door when reaching the limit of its movement in either direction and also for retaining the lugs 19 of the actuating members 18 in engagement with their respective feed grooves 6.

If at any time it is desired to manually open or close the door 52, the same may be moved as the over-running clutch 7 is prowided which will permit manual movement of the door Without causing operation of the door actuating means.

l/Vhile I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and. scope of the invention as claimed.
