Patented May 22, 1934 UNITED STATES PATENT OFFICE 5 Claims.

This invention relates to new and novel improvements in door operating devices and while adapted for use generally on any type of closure device to which it may be advantageously applied, it is particularly intended for use to open and close garage doors and in which connection it will be herein illustrated and described.

Objects of the invention are to provide door opening means of simple, durable construction which may be constructed at a low cost and which may be conveniently operated and which in use will be very eflicient and reliable.

A particular object is to provide a practical door opening and closing means which will ins clude efficient door locking means both of which may be operated by a driver of an automobile without leaving the drivers seat.

A further object is to provide efiicient door operating and locking means which may be operated from a vehicle positioned in the driveway in spaced relation to the doors and which may be quickly and conveniently installed on a garage of ordinary construction without excavating and without necessitating any substantial alterations in the garage structure.

The above objects are accomplished and additional ends are attained by the novel construction, combination and arrangement of parts hereinafter described and illustrated in the accompanying drawings, in which I have shown a preferred form of the invention, it being understood that the invention is capable of various adaptations and that changes and modifications may be made or resort had to substitutions which come within the scope of the claims hereunto appended.

In the drawings like characters of reference are employed to designate like parts as the same appear in any of the several views and in which:-

Figure 1 is an interior, elevational view of the front side of a garage equipped with a door opening device constructed in accordance with this invention, portions being broken away-to conserve space and parts being shown in vertical section.

Figure 2 is a horizontal, sectional view taken as indicated by the lines 2'2 of Figure 1 and showing in plan door opening and closing means constructed in accordance with this invention.

Figure 3 is a similar view somewhat diagrammatic in character showing the door in an open position.

Figure 4 is a vertical, longitudinal, sectional view taken as indicated by the lines i-4 of Figure 1, parts being broken away to conserve space.

Figure 5 is a fragmentary view showing in elevation, a portion of the door locking mechanism employed in carrying out this invention.

Figure 6 is a view in end elevation showing the tube which projects forwardly from the garage to support operating and locking means, the same being taken as indicated by the lines 6--6 of Figure 4.

Figure 7 is a vertical, sectional view taken as indicated by the lines 7-7 of Figure 1.

Figure 8 is a similar, sectional View taken as indicated by the lines 8-8 of Figure 7.

Figure 9 is a central vertical sectional view taken as indicated by the lines 9-9 of Figure 6.

Proceeding now to a detailed description of the invention with reference to the particular adaptation thereof disclosed in the drawings, the numeral 10 is used to designate one lateral wall of a garage and the numeral 11 the other lateral wall thereof. The numeral 12 is used generally to denote the forward wall which is provided with a suitable door opening, V

The numeral 13 denotes the door frame and the numerals 14 and 15 doors which are secured in said frame for outward opening movement by means of the hinges 16. The numeral, 1'? denotes a roller mounted in suitable brackets 18 to extend between the walls 10 and 11 in parallel, spaced relation to the forward wall 12. An arm 19 is secured to the door 14 at a point adjacent the upper side thereof by means of the hinge 20. The arm 19 projects inwardly through the guide bracket 21 which is suitably secured to the garage structure. The arm 19 is horizontal and projects rearwardly immediately below the roller 17. A rope or other flexible member 22a is wound around the roller 17 at a point adjacent the bracket 21 to provide a plu- 7 rality of convolutions. One end of the rope 22 is extended rearwardly and is secured to the inner end of the arm 19. The numeral 23 denotes a sheave which is secured to the garage structure at a point rearwardly from the innermost movement of the inner end of the arm 19. The other end of the rope 22 is operatively positioned around the sheave 23 and is suitably secured to the inner end of the arm 19. The arm 24 is likewise secured to the door 15 by means of the hinge 25 so as to project inwardly of the roller 17. The arm eX- tends through a suitable guide member 26 which is similar to the guide member 21 and a rope 27 is suitably secured to the inwardly projecting end of said arm 24. The rope 27 passes around the sheave 28 which is similar to the sheave 23 and is similarly mounted on a garage and is then extended inwardly and wound around the roller 17 in a plurality of convolutions 27a. The other end of the rope 27 is also secured to the inner end of the arm 24.

It will be seen that a rotary movement of the roller 17 will cause the ropes 22 and 27 to be wound thereon to move the arms 19 and 24 inwardly oroutwardly in accordance with the direction of rotation. The numeral 29 denotes a rope which is wound around the roller 17 at a point adjacent one end thereof in a plurality of convolutions 29a. A weight 30 is attached to one end of the rope 29 and is adapted to operate the roller 17 and normally move and hold the arms 19 and 24 in an outward position. The rope 29 extends downwardly over the sheave 31 which is positioned directly in front of the tube 32which is entered through a suitable opening in the. forward wall 12. The tube 32 projects forwardly from the wall 12 at a point where the doors may be conveniently operated from an automobile or other vehicle.

The numeral 33 denotes a standard which is secured to the pipe 32 to support it'in a horizontal position. The rope 29 extends through the tube 32 and is provided on the outer end thereof with a suitable handle 34. A weight 35 is mounted on a rope 36 which passes over the sheave 37 and is attached to the rope 29 by a sheave 38 for the purpose of taking up slack on the rope 29. Each of the arms 19 and 24 are provided on the upper side thereof with a block 39. A catch 40 is hingedly secured to each of the guide members 21 and 26 whereby the members 19 and 24 with the doors in a closed position will be held against opening movement by the catch 40 which engages the lug 39 as shown in Figure 7. An L-lever 41 is pivotally secured to each of the guide members 26 and 21 at a point above and adjacent the catch 40. One arm of the lever is secured to the catch 40 by the connecting member 42. A wire rod or other connecting means 43 is secured to the other end of said arm. A similar connecting member is mounted on the bracket 26 and the wire 43 is similarly connected to each catch. The wire 43 is connected to an L-lever 44 which is secured to the inner side of the garage at a point spaced above the inwardly projecting end of the tube 32. The other end of the L-lever 44 is connected by means of a wire or other connecting member 45 to a lever 46 which is fixedly secured to the inwardly projecting end of a stem 48, which projects forwardly from the inner end of the pipe 32. The stem 48 extends outwardly through the pipe 32 and terminates at the outer end thereof in a key operated means 49. A rope 50 is wound around the roller 17 in a plurality of convol-utions 50a and in the opposite direction to the convolutions 29a whereby the rope 50 may be seized to rotate the roller 17 and close the door from a point on the inside of the garage. It will be seen that the handle 34 may be seized and a pull exerted on the rope 39 torotate the roller 17 and move the arms 19 and 24 inwardly to the position shown in Figure 2. As-the doors are thus pulled to a closed position, the lug 39 is moved inwardly beneath the catch 40 and the catch 40 engages the outer edge of each lug thereby holding the door in a closed position. This closing movement of the door winds the other end of the rope 29 upwardly and leaves the weight 30 in a raised position. As the handle 34 is released the weight 35 operates to take up the slack in that end of the rope 29.

To open the door from the outside, the automobile or other vehicle is driven to a point where the outer end of the tube 32 is readily accessible. A key is inserted in the lock 49 and the stem 48 is rotated to impart a swinging movement to the arm 46. This moves the lever 44 and raises the catch 40 whereupon the weight will automatically impart a rotary movement to the roller 17, which will move the arms 19 and 24 outwardly and open the doors14 and 15.
