UNITED STATES EDWARD EARL WHELER, OF

TORONTO, ONTARIO, CANADA.

GARAGE-DO OR- OPERATING MECHANISM.

Application filed April 20,1923. Serial No. 633,400.

To all whom t may concern:

Be it known that I, EDWARD EARL lVi-Innnn, a subject of the King oi'Great Britain, and a resident of the city of Toronto, in the county ot York, in the Province ot Ontario, Canada, have invented certain new and useful Improvements in Garage- Door-Operating Mechanisms, of which the following is the speciiication.

My invention relates to improvements in garage door operating mechanisms and the object of the invention is to devise a simple and cheap construction of device for automatically opening and closing a garage door when an electric circuit is closed at a point remote 'from such door and it consists essentially ot the arrangement and construction ot parts as hereinafter more particularly explained by the following specification.

Fig. 1 is a sectional plan view of a garage showing the doors in the open position or the position which they and themechanism assume when the automobile is within the garage and the doors are in the open posil5 tion ready for the automobile to leave.

Fig. 2 is a vertical section through the upper portion of a garage showing my operating mechanism carried by the roof thereof.

Fig. 3 is an enlarged detail of the main operating levers, the central portion of the levers being shown in section.

Fig. 4 is an enlarged side elevation of the lever locking mechanism.

Fig. 5 is a cross sectional View on line .5i- 5, Fig. 4.

Fig. G is a sectional detail ot the latching mechanism connecting the operating levers together.

Fig. 7 is a sectional detail of the doorV The devices 19 and 20 are shown in detail in Fig. 4. In this figure 21 indicates a casing which is secured to the base plate 10 and in which is located an electromagnet 22 provided with an armature 23 swung. at 24 on a lug 25 forming part of the casing. The numeral 26 indicates a locking lever pivoted in the lug 27 forming part of the casing and bearing at its upper end against the springheld depressible member 28 which is pivoted at 29. Wires 32 and 33 lead from the electromagnet 22 of the locking device 19. vThe wire 33 leads to a circuit closing switch located in the driveway at a point remote from the garage and mounted upon a standard 35. The wire 32 leads to one te rminal of the battery 43, the wire 32X leading to the other terminal of the battery 43.

The circuit closing switch 34 comprises an outer circular casing 36 having a circular opening 37 in its .front face provided with diametrically opposing edge notches 38 and 39 to permit the withdrawal of the lock.

The barrel 40 of the lock is of a construction commonly employed such as in a Yale lock in which the barrel may be 'forced against spring pressure inward when the key tits the wards of the lock.

When the inwardy movement of the barrel takes place operated by the key the barrel '40 engages a spring contact piece 41 and forces it into contact with a stationary contact piece 42 to close the circuit, which circuit consists oi: the wires 32,32X and 33 hereinbei'ore referred to, the wire 32 leading to the battery 43, the opposite end portion 32 of the wire 32 leading from the battery to the circuit closing switch 34.

The numeral 44 indicates a wire leading from the Wire 32 at the point 45 and connected at its opposite end to one of the ter- `minals of the electromagnet of the locking device 20. Theother terminal. of the inagnet is connected by a Wire 46 to aspringpressed contact 47 located in the door Jamb of the door 2, The numeral 48 ind1cates an opposing contact carried by the inner edge of the door 2 and adapted to engage with the contact 47 when the door 2 is closed.

The numeral 49 is a Wire leading from the contact 48 and connectedat its opposite end to the Wire 32 at 50. The numeral V 51is a pulley mounted upon the lever` 13. The numeral 52v is a cord secured to the inner end of the lever 13 and extending around the pulley 51 on the lever 12 andV at its opposite end over a pulley 52x carried by bracket 53 mounted upon the wall of the gara-ge. The numeral 54 is a weight carried by the lower depending end of the cord 52. The

Vrear end ofthe lever 12 is connected by link rods 55 and 56 to the pins 8 and 9. The `numeral 57 is a spring-pressed latch mounted in a bracket 58 carried by the lever 12 and adapted to engage the lever 12 when the levers 12 and 13 are in a position superimposed one over the other. The numerals 60 and 61 indicate stops depending from the opposite side ofthe lever 13 and engaging the corresponding side of the lever 12 when the levers are parallel.

' Having described the principal parts in- Y volved in my invention I will briefly describe the operation of the same.

It will vbe understood that the weight 54 is inan intermediate position, that is, half way between its extreme upper'and lower positions during the night, and when the doors are open in the morning the weight is raised to its upper or -final position for operation. In the morning, the owner of the garage opens the doors 2 and 3,'thereby pulling the lever 12 from the position A beneath the lever 13 to the position B, shown inv full lines in Fig. 1, the levers 12 and 13 being first released one from the other so that the lever 12 may be moved independently of the lever13, the lever 1 2 being released i'rom the lever 13 by pulling upon the cord 59 secured to the latch 57.

As above stated, by the opening' oi the doors, the weight 54 is raised to its upper or final operating position. When the automobile has passed out from the garage,

v the operator inserts a key in the .switch 34 thereby closing the circuit formed by the Wires 32 and 33 so as to energize the magnets 22 and thereby raise the armature 23 so as to release the lever 26 and free the lever 12. The weight 54 then servestoturn the lever 12,- (the lever I3 being looked in a stationary position bythe lock 20:), swinging it past the dotted position shown at 13", beneath the lockedlever 13, thereby draw-4 ing the doors to the closed position, the movement of the lever 12 being limited by the stops 60 and 61 carried by the lever 13. Then in this position, the levers 12 and 13 are superimposed, one over the other, and are again locked together by means of the latch 57. v

When the automobile returns at night, the operator ain inserts his key in the switch 34 to c ose the contacts 41 and 42, thereby releasing the lever 13 which is then drawn rearward together with the lever 12 which is locked thereto by the latch 57, so as to open the doors and permit the entrance of the automobile. When the automobile leaves the garage and the operator inserts his key in the switch 34,the lock 19 is necessarily operated, the-circuit connecting 1i.

the switch 34 lto the lock 20 being broken at 47 and 48. When the doors are closed,

the circuit to thelock 20 is again made at 47 and 48 so that when the operator desires to open the doors upon returning,.the cirf cuit to the lock 2O is closedby the` insertion-1 1 of the key in the switch 34.

What I claim as my invention is:

1. In a garage door operating mechanism, the combination with the doors, of aver- .tically movable weight means for rais ing the weight to the limit of its up- Ward movement by the opening of the door, weight releasing means operated remote from the doors and located exterior to the arage, mechanism operated by the partialv all of the wei ht for closing the doors, means for holding the Weight stationary after its partial fall, and means for opening the doors operated by the further 'or final fall of the Weight when again released after the partial fal f Y 2. In a garage door operating mechanism, the combination with the` doors of a pair of swingably mounted levers carried by the roof of a. garage andadapted to be carried nil los

from an aligned to a crossed position by the opening of the doors, a link connection between oneend of one of the levers and the doors, electrically operated means for independently locking each ofthe crossed levers in their crossed position, 'a cord attached to the opposite end of the aforesaid lever connected to the doors, a pulley carried by the corresponding end of the lever crossed with the door connected lever and around Whichthe cord passes, a pulley carriedby a stationary support and over which the cord passes, a weight suspended by the oord,

and manually releasableV meansl for auto-L matically locking Vthe levers together when the released door connectedlever is brought by the partial fall of the weight into an aligned position with the lever crossedr therewith whereby both levers are carried by they Weight in the opposite direction to open the doors.

3. A garage door operating mechanism comprising a pair off crossed levers one of which vis connected to the doors,ele`etrically operated means at one end of each lever for locking the levers in a stationary and crossed position, means for latching one lever to the other when brought into an aligned position, means for carrying the door connected lever when released from a crosswise position to an aligned position with the other lever to close the doors and Afor carrying the crossed lever and the door connected lever engaged therewith in the opposite direction to open the -doors, and means operated remote from the garage for releasing the lever locking mechanism.
