'Ano'bject of the invention'is to provide a simf Patented Feb. 20, l 940 UNITED}? STATES I A* lE T GARAGE pool: I e H William MQWina ns, Mama, c ne v ApplicationOctoberil i, images; atasha; .4 Claims. (o1. -268- -)1 This invention relates to door operating means and more'particularly to such p le, practical and inexpensive mechanism for opening and closing garage doors and th'eliket Another object is to provide a n'iechanism of the character described adapted for actuation at a distance from the door and conveniently located h within-reach of a driver of a motor vehicle'while seated'therein. Y Another object is to provide a mechanism of the character described having incorporated therein novel locking means.

Other objects and advantages will appear and be brought out more fully in the following specification, reference being had to the accompanying drawings wherein Fig. 1 lustrating my invention applied thereto.

Fig. 2 is a top View of the same. Fig. 3 is aside view of the same.

Fig. 4 is a view in elevation of an operating arm. I i

Fig. 5 is a plan view of the same. Fig. 6 is an enlarged side elevation of the same.

' Fig. '7 is an end View of the operating handle.

Fig. 8 is a sectional view taken along the line 8-8 of Fig. 6 and p i Fig. 9 is an enlarged view: illustrating a portion of the locking means.

Referring more particularly to the drawings,

I show a wall portion ill of a building such as a p 7 parent from the foregoing description. Handle 3? is grasped and a downward pressure'thereon" .35. "and on lever 36 will engage the clutch and for garage or the like having'a doorway l land a door l2 having two or more supporting brackets l3, 1

each carrying a roller i4 adapted to have rolling engagement with track it suitably mounted on wall it.

a guide roller it which also rides on'track IS.

A pair of cylinders i9 and 2 0 are supported as" by brackets 21 towall H] and receive the ends'of a with acylinder 26 and a pipe 27 connects cylinder 2il'with a cylinder '28fcy1inders26 and 28 being mounted in a suitable housing 29 adapted to be placed in the ground adjacent the driveway leading to the garage.

Apiston ttis reciprocable between

cylinders

26 and 28. An upstanding hollowrod'or pipe 31 is connected by'suitable .fittings 32 to piston means "applied to i v with a suitable handle-.37.,

and are'sutured to form gafclutch' and asp ring 35 is suitably positioned therein tonormally-keep 5 the'pipeszs eparated. -A lever arrn 36 is secured by an elbow 35a to pipett and may be provided ,Door is is piovided'witha roc piece mat e 7 ed for interfittingengagement witha lock-piece .39 inounted'on wall it and a lock'ba'r 40 is slide able in bracket 4i on door Hi and is connected at-its upper end to a link fiz secured to the end of a stiff wire or cable 43 in pipe 21, the other end of wire 43 terminating in housing 29 and-1 being connected toa tubularmemberM mount-ff edin bearing piece ifi'on cylinder 28. Tubular member M has a squar'e'bore into which a squared rod 46 is slidabl'y positioned.

A gear ll is secured to rod 46 within fitting -20 1 32 and a gear it which meshes with gear 41 is secriredtothe lower end of a wire or flexible cable it which extends through pipes 3|, 33 and lever 36. j A suitable armored tube 50 or the like is secured in elbow 35a to prevent twisting ch wire 48 during operation. l

A lock 51 is mounted in handle 3'! andis connected-t-o the end of wire M.- Pipes'25 and. 21 and cylinders 1%,

2i

26 and 28 are filled with oil. To prevent leakage of the same, suitable packing glands 52 are securedto theends of pipe 2i where'the ends of wire {l3 extend therethro'ugh;

The operation of the invention should be apdoor I2. A reverse movement of lever 36 and I piston 31] will create oil pressure in cylinder 26,

' pipe 25 and cylinder-E Q Which will be transmitted" 45 to. piston 22 and lazy-tongs causing the. latter to contract, thus closing the door. [2. vPrevious to the opening: of thedoor, lOCk I'Odydfi will havebeen released from ,lock member. 38 by akey in lock 5! which, when turned, turns wire}! 50 v I which turning movement is transmitted through gearsf ltand 41 and, rod 46 and tube 44 to wire 43 which is connected to link 42, the latter being I connected to rod 40. Similarly, after closing the 'door, the key in-lock 5| will by reversemovement, 55 t cause rod Ml to lock

members

38 and 39. The spring 35 which separates pipes 3| and 33 permits lever 36 to be swung out of the way when not in use and if accidentally struck by a motor vehicle, it would swing out of the way and prevent injury to the same.

It will beunderstood that the foregoing description is illustrative rather than restrictive of the invention and that changes and modifications may be made Without departing from the spirit and the scope of the subjoined claims, for instanceFThe relative size of cylinders I9, 20, 2B and 28 as well as the length of

pistons

22 and 30 may be varied in practice as may be required to vmeet variousactual conditions, such as difierent weights and sizes of doors, taking into account the force necessary to move them.

Having described my invention, what I claim is: l. A mechanism of the character described, comprising a door suspended from an overhead track, a'pair of spaced cylinders parallel-to said track, a piston within the cylinders and spancomprising a door suspended from an overhead track, a cylinder parallel to said track, a piston in said cylinder, lazy tongs having one end connected to the door and the opposite end connected to the cylinder andhaving a roller traveling on said track, an arm connecting one of the pivots of the lazy tongs with the piston, and fluid pressure for operating the piston.

3. A mechanism of the character described, comprising a door suspended from an overhead track, a cylinder parallel to said track, a piston in said cylinder, lazy tongs having one end connected to the door and the opposite end connected to the cylinder and having a roller traveling on said track, an arm connecting one of the pivots of the lazy tongs with the piston,-and a remote control fluid pressure system for operating said piston.

4. A mechanism of the character described, comprising a door suspended from an overhead track, a pair of spaced cylinders parallel to said track, a piston'within the cylinders and spanning the space between the same, a fluid pressure system for operating the piston in said cylinders for moving the piston in opposite directions, lazy tongs connected at one end to thedoor and its opposite-end connected to one of the cylinders, a pin carried by the piston and connected to one of the pivots of the lazy tongs, a fluid pressure system operating the piston, and a remote hand operated piston in the fluid pressure system for operating the pistons for operating the lazy tongs.
