OPERATING MEANS FOR DOORS.

To all whom it may concern:

Be it known that JOHN Sol-101m, a citizen of the United States of America, residing at Davenport, in the county of Scott and State of Iowa, has invented certain new and useful Improvements in Operating Means for Doors, of which the following is a specification.

My invention relates to improvements in apparatus for opening, closing and fastening doors for garages and other structures.

The objects of my invention are, first, to provide an apparatus by the use of which the driver of an automobile may open the doors of a garage to drive into it without getting out of his car and may close the doors after driving out of the garage, without getting out of the car; second, to provide an apparatus which will automatically lock the doors in open or closed position; third, to provide a simple, cheaply manufactured and easily operated locking device adaptable for use upon doors and other moving objects.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a top or plan view of a garage embodying my invention, but with the roof removed; Fig. 2 is a side elevation of the operating post; Fig. 3 is an enlarged detail of the locking apparatus, showing a plan view thereof; Figure 4 is an edgev view of the locking apparatus; Fig. 5 is a detail plan view of the locking apparatus showing one 'of the bolts or latches retracted from its locked position; Sections AA and B-B, are cross-sections upon the lines AA and BB of Figure 3, respectively.

My invention comprises links, 4, each of which has one end pivoted at 5 to an operating lever, 6, and its opposite end pivoted in a suitable socket, 23, secured to a door, 2, of the garage.

The operating lever, 65, is fulcrumed at 7 upon a suitable support, 7, which may be a timber secured to joists or rafters, 29, of the garage or in any other suitable manner. The support, 7 should be secured in a position which would allow the travel of the pivot, 5, to occur as near midway of the garage from side to side as circumstances permit.

A semi-circular rack, 8, preferably of band iron or other suitable material, is secured to the support, 7 and provided with notches, 9 and 10, adapted to receive and engage the inner ends of the bolts, 11'and'12, respectively. Thejnotches, 10 and 9, are located at points upon the rack, 8,- which approximate the extreme travel of the lever, 6, so that when the doors. are fully open or fully closed, the notches, l0 and 9, will engage the locking bolts, 11 and 12,-respectively.

A head, 25, is secured to the end of the lever, 6, oppositeto the pivot, 5. The head provides bearings, 23 and 24, for the bolts,

.11 and 12. The lower end of the'bolts, 11

and 12, are preferably formed square, tofit in the square holes or sockets, 24 and prevent turning. The opposite ends of the bolts, 11 and 12, are preferably round so as to slide readily in the openings, 23.

A compression spring, 22, is. mounted upon each of the bolts, 11 and 12, one end of which bears against the outer portion of the head and the other end of which bears against a shoulder formed upon the bolt so that the expanding action of the spring. will.

drive the bolts, 11 and 12, int-o their respective' notches, 10 and 9, when in proper position therefor.

An oscillating or rocker bar, 13, is pivoted to the head,-25, and provided with an opening, 14, opposite the pivot to permit the attachment of an operating cable, 15., The ends of the oscillating or rockerbar, 13, are

provided with openings, 13*, to receive links,

11 and 12 respectively. The inner ends of these links are suitably secured to the upper ends of the bolts, 11 and 12, and the outer ends are provided with heads, 21 and 20, to secure them to the oscillating or rocker bar, 13.

The lever, 6, is preferably formed of two iron bars, as shown in Figure 4;

.A cable, 15, is secured to the osclllating or rocker bar, 13, by passin through the hole, 14, or, any other suitable method and passes over or around a sheave or pulley,

16, secured on the side of thegarage and thence out through suitable openings above the garage door to and over' pulleys, 17, suitably secured to a post, 19, and down, and around a] second pulley, 18, secured to the post, 19, a suitable distance below the pulleys, 17.

In the operation of my device, when the doors are shut as'shown in solid lines in Figure 1, the left hand line of the cable shown in Figure 2, 'is pulled downward;

This pulls the oscillating bar, 13, toward the pulley,- 16, and as the oscillating bar rocks on its pivot, it raises the link, 11 thus pulling the bolt, 11, out of the notch, 10, and unlocking the doors. The continued pull on the cable then carries the head and the end of the lever, 6, to Which it is secured, around to the position, shown in dotted lines in Figure 1, and when it reaches that-position, the bolt or latch, 12', drops into the notch, 9, and locks the doors in the open pos'itionand also looks the lever, 6-, against further movement toward the pulley, 16;

This looks the doors against being blown shut by the Wind and the car can then be driven into the garage safely. Upon driving the car out of the garage, the driver can pull the right hand cable as shown in Figure 2, downward, which will reverse. the movement or the rope, unlatc-h the bolt, 12, from its notch, 9, carry the head of the lever, 6-, around to the closed position. shown in solid lines in Figure 1 and as th bolt, 11, drops into the notch, 10, it will lock the doors in closed position and they will remain locked until released by again pnllingthe rope or cable, 15.

Short pieces of rope may be attached to the cable, 15, at appropriate places inside "of the garage, so that the doors can be opened or closed, from the inside oi the garage as well as from the outside and additional means may be provided for locking the lever, 6, in the closed position which can only be operated from inside the garage or the doors may be secured. by the ordinary hasp and padlock or other suitable means on the inside of the garage.

It is obvious that this device, with slight modifications, can be used for sliding doors, Which I have illustrated in an additional application for patent which I filing in connection herewith and that this form of lever movement may be adapted to a considerable variety of otherpurposes; also that he lockingandunlocking mechanism in say be applied to a large variety o1 levers and utilized for many different purposes.

The form, size, proportions and position of the different parts of my invention may be varied to suit the requirements each particular case as occasion arises.
