noon-OPERATNG MEANS.

Application ledllarch 31, 1926. Serial No. 98.812.

My invention relates to door-'opening and closing means permitting of a person'effecting an opening or closing of the doors at a point somewhat remote therefrom.

The invention more particularly relates to the type of door-operating means shown in United States Patent No. 1,508,270, granted to lne September 9, 1924, in which a switch is mounted on a post or the like distant from a garage or other structure, the doors of which are to be opened and which includes an electric motor having operative connec tion with the doors as well as manually operable switches in circuit with the motor to throw the motor into and out of action and to place the doors underl the control of the operator.'

The general object of my present invention. is to provide a door-operating means of the general type referred to improved in various particulars especially with regard to the means to operate a traveller from the motor as well as with respect to the circuit and the devices embodied therein.

The nature of my invention, its' distinguishing features and advantages, will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this speciiication, it being understood that the drawings are merely illustrative of one example of the invention. I v

In the illustrated example of my invention the numeral indicates a structure which may be a garage or the like. The structure 15 is shown with swinging doors 16 to open and close by mechanism compri-sed in my improved devices. To each door is pivotally secured a rod 17, said rods being convergent and connected at their inner ends with an element 18 advantageously in the form of an angle bracket, said element 18 having a stem 19 bolted thereto, said stem having a plunger 20 operating in a cylinder 21. Springs 22 in cylinder 21 bear against opposite Vfaces of a plunger 20. The cylinder 21 with the springs 22 and plunger 20 with stem 19 form an indirect -connection between the head 18 and atraveller 23. Said traveller is driven by an endless chain 24, the`illustrated .connection being by a stud 25 on chain 24 and entering a vertical slot 26 in traveller 23, said stud having a. roller 25.

The chain 24 runs over an idler sprocket wheel and a driven sprocket wheel 28 driven in any suitable manner from the shaft on an electric motor 29, there being a reducing gear 30l conventionally indicated in the pres: ent example as the drive connection between the shaft 29 and driven sprocket 28. Said reducing gear is of ywell known form and does not constitute part of the present invention and therefore needsno further velucidation. The traveller 23 has a tubular guide bar 32 in a frame 33 which also mounts the motor 29. In practice, rods 17 have incorporated therein` turnbuckles 117 for adjustment.

Frame 33 has a longitudinal switch shifting bar 34 mounted in the ends of the frame to have limited sliding movement thereby when said rod is tripped by traveller23 as y switches 48.l

the opposite end. A switch base 36 is disposed adjacent the rod 34 between two tingers 37 on'said bar 34. To swltch base 36 are pivotally secured two switch blades 38, 39, said blades having fixed pivots 40, about which the blades may rock. The swltch blade 39'is adapted to have contact with switchleaves 41, 42 and the switch blade 38 is adapted to have contact with two switch leaves 43, 44 according to the direction 1n which the base 36 is moved by the fingers 37 on shift rod 34.

Relays 45,-46 are provided in clrcuit wlth motor 29'; in said circuit also are pairs ot manually operable and normally closed switches 47 as well as manually movable In the motor circuit alsoand remote from the doors 16, to be controlled by one approaching or leaving a garage, for example, is a switch designated generally by the numeral 49 which 'is key-controlled,-

being provided with switch lock 50, the numeral 51 indicating a lock for the casing of switch 49. The switch 49 includes a lswitch assemblage 62 having spaced terminal emergency stop for the doors and includesv spaced terminals 56 and a slide 57 having a bridge piece 58. Slide 57 is subject to a spring 59 and slide 54 is subject toa spring 60. The spring 60 normally tends to maintain the switch open by maintaining the bridge piece 53 out of engagement with the terminals 52. Springl 59 normally maintains switchI assemblage 63 closed. The switch 49 is here shown as mounted on a post 61.V

The switehes47 and 48 may be anywhere conveniently located about the structure 15.

With the above described'assemblage, the traveller 23 serves to actuate the door-operatingy rods 17. With the initial movement of said traveller 23 in either direction the force exerted by the'traveller is absorbed by the springs 22' and upon compression of a spring, the movement of the cylinder 21 with the `traveller will act on the plunger rod 19 and through the element 18 or equivalent connection, the rods 17 will be moved to swing the doors 16. As traveller 23 approaches a sprocket wheel 27 Vor 28, a finger 123 on said traveller engages a trip 35 ork 135 to shift rod 34 for making or breaking the circuit through the fingers 37 trated circuit for carrying out the example of the invention shown. In the normal position of the parts when not in operation, the circuit is open at the armatures 145, 146 because the relays 45 and 46 are de-energized- When the motor is not running and the dcscribed automatic switch controlled by the shifting fingers 37 is conditioned for an operation, either for opening the doors 16 or closing the same, after a previous operation, then, the switch blade 39 may be engaged with switch leaves 41 and 42 and therefore in electrical connection with said leaves, or, switch blade 38 may be engaged with the switch leaves 43, 44 and therefore in electrical connectionv with said leaves 43, 44. The switch blades 38, 39 are insulated from each other by the base 36 and operate without contacting with each other. The switch operating fingers 37 move the switch blades simultaneously so that the blade 39 will contact with leaves 41, 42 or the blade 38 will To open the doors either of the switches `by wire f to and through switch leaves 41,

through blade 39 to wire g and to the winding of relay magnet 45 energizing said magnet and attracting the armature 145, bringing said armature into contact with the terminal h associated with the wire d. Hence, the circuit will be closed between the armature 145 and said terminal h so that the current iows from wires a and b to the wire d which connects by wire Z with switch leaves 43. It will be observed that at this time a circuit is established running from leaves 4 1 and blade 39 to and through switch leaves 42 and by wire to switch leaves 44 and by wire j to motor 29 and to the negative lead 7c of the supply circuit. Themotor 29 now receives its current for continuous operation of the motor for the opening of the doors.

It is to be noted here that when the ingers or hand which temporarily maintained a Switch 48 0,1' the switch 62 closed, is removed from said switch, that is temporarily closed, the circuit is broken through said temporarily closed switchbut the motor is in circuit with the supply leads through the -energizing of relay 45 and thus the current flows through armature 145 fand terminal h and -wire d to the motor. connectionsdescribed. As4 the motor operates, it drives the sprockctwheel 28 and through chain 24 causes the traveller 23 to move toward the trip on rod 34. Upon the engagement of the finger 123 ot traveller 23 with the trip. 35, rod 34 is moved longitudinally, thus causing the lingers 37 to throw the lswitch blade 39 out of engagement with the 145 to drop out of engagement with terminal h, whereby all opation of the apparatus is stopped. and the doors will have arrived at the open position.

The automatic switch involving the blades 38, 39 when the motor 29 and relay 45 are thrown out of operation as described, conditions the apparatus for the closing opera'- tion of the doors. blade 38, it is to. be noted, isengaged with the leaves 43, 44 and the switch blade 39 is' out of engagement with the switch leaves 41, 42. l

In order to effect the closing of the doors 16, one of the switches l48 is thrownto the closed position or the switch62 lis closed by switchassemblage G2 by turning the key in the direction of the arrow' marked operate in Figure 7. The temporary/closing of the circuit through the normally closed switches.

63 and 47 and through a temporarily closed switch 48 ory switch 62 and wires d and l, to switch leaf 43, through switch blades 38 by wire Z, to the winding of relay magnet 46 and through said magnet to negative supply lead c. At the same time current flows from leaves 43 and through switch blade 38 to switch leaves 44 and to wire j and through the motor 29 to negative lead k. As the motor is thus energized for the closin of the doors, thesprocket 28-is again driven, and therefore, sprocket chain 24, until the linger 123 of traveller 23 engages the trip 135 and again through iingers 37 shiftsl switch base 36, thereby throwingthe switch blade 38 out of engagement with the switch leaves `43, 44 and throwing the switch blade 39 into engagement with the switch leaves 41, 42. As the current is broken at the switch leaves 43, 44', the relay magnet 46 and the motor 29 will be cut out and the doors will have reached their closed position.

If it should be desired to arrest either the At this time the 4switch the insertion of al key into the lock 50" of switch 49 to close the circuit through.

I would state furthermore that while the illustrated example constitutes a'practical embodiment of my invention, I do not limit myself lstrictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.
