To all 'zrizcm 'nmy owz cer' n:

Be it known that 1, Fin-in lifnrnn, e citizen of the United fit-ates, a resident of lehiu, in the county of lazewell and State of Illinois, have invented new and useful 11n- PTOVEDIGDM in Door ()pening and Closing Devices, of which. the following is a specification. I

This invention has inc; and closing dcvi and has for its prh 'pel object to provide as'ini pens. re and yeteffecti've device of this character applicable ',ularly to doors, and including 31192118 for operating such a device within the garage, or at a suitaliile point removed therefrom; whereby, when approaching the garage the driver of an automobile may open the garage doors without alighting; from the car. i

The invention has for a further object, spring means to assist in moving t e doors to open and also closed position, re predetermined novenient of the operating means, and also 1116)? s for holding the doors in open position accidental closing, due to wind pressure.

That the invention may be more fully understood. reference is had to the accompanying drawings forming a part of the present des irtion, illustrating a preferred embodi menu of the invention, in which:

1 a top plan view of my 1111- door opening and closing device applied to garage doors, the gar-ago being shown in dotted lines in a diagraini'natic way, with the garage doors in full lines, closet l io'ure 2 is a view except that the doors and the door opening: open position, and 7 Fi nre 3 is av detail of parts of thedevice, as the some would appear, if taken on the line 3-3 Figure 2.

Like characters of reference denote corresponding parts throughout the figures.

In providing a. door opening and closing device for a garage, or similar building, it will be understood that the door operating means must be so located that an automobile, car or truck moving into and out of the building will not encounter such device, or interfere with it, or be interfered with, and therefore, evoen though 1 have elected .erenceto door openc more 1:) roves:

similar to Figure 1, are in open position device also moved to to show thedevice in'nnediately beneath the ceiling of the building and within the interior of the building, it could conveniently be located in a coin zartinent below the floor ofthc building and be operated with as good results. And while Ihave shown the garage as having two hinged doors-the Oll'liSSlGD of parts will enable it to be connected to one door and operated with as good results.

'Yl A, being preferably shown in dotted lines, except the two doors, 13,13 hinged thereto and adapted to be swung toward and from each other. A. supporting beam C is shown to which are connected certain operative parts of the device.

1, 1, designate similar connecting barf; which have a suitable pivotal connection, at

'2, with the doors B, and normally converge to a meeting point and have a pivotal con= nection with a control rod?) chnnected to ing point of the bars 1, when in closed, as well as when in open position,- controlled by the rod '3, is at a point on an imaginary line passing through the center of the garage and intersecting the meeting edges of the doors B, see Figures 1 and 2.

In practice the meeting ends of the bars,

1. lie garage or otherbuilding is designated swing freely from the beam C. The meet? connection with the beam C, and the latter to provide for the connection of the bars 1, 1, therewith, and also a link 6 and a rod 7 forming a connection for a coil spring 8,

the rod 9 from the opposite end, of which,

has a pivotal connection with the beam C.

To the beam C, and to one side of the dev ce, is journaled a-pulley wheel 10, over which is guided a rope or cable 11, the inner end of which is connected to the link 6 and the forward portion of said rope or cable leads to one side of the garage, just inside the door, and passes over one or more guide pulleys l2 and 13, with a section, not shown, depending within reaching distance inside the garage, and the section 11 passing out through the wall of the garage and led to a point in advance thereof where it passes a pull on the rope or cable 11 will move.

the bars 1 outwardly,.their inner pivotally connected ends swinging an an are of a circle described by the outer end ot the control rod 3 swinging on its pivot on the beam C, and due to .such movement the doors B are started nroving to open position. At the same time the pull is against the tension of the spring 8 which expands, until it is swung across the pivot of the rod 8, with the beam C. il hen said spring contract-s, pulling the connected ends of the bars 1 and the end of the control rod 3 into the position shown in Figure 2, resulting in the doors'B being forced to the full open position shown in said Figure 2, and held in such position and prevented from closing due to wind pressure.

To close the doors l3,a corresponding pull on the rope or cable 11 will cause the control rod 3 to retraverse its path of travel, drawing the bars 1 inwardly and swinging their inner ends in an arc of .acircle described by the movement of the outer end of the control rod 3,.agai'n expanding the spring 8, which, assoon as it crosses the pivot point of the rodS with the beam C will contract, )ulling the connected ends of the bars 1 and the end of the control rod 3 into the position shown" in Figure 1, re sulting in the doors B being closed, as shown in said Figure 1, and held in such closed position. I

- It is obvious that the location of the rope or cable and control rodand spring may be initially placed at either side of thebuilding andcoperate with as good results. It is also obvious 'that if only one ooor is used, one of the bars 1 could be omitted, andthe device used with equally as good results.

Thedevice is simple, inexpensive, effective and may be conveniently applied and operated by an unskilled person or child. The slightest pull will position the parts so that the full opening orclosing of the doors will have the assistance of the spring 8, as will be understood.

iVhat I claim is In a door opening and closing device, in combination, a pivotal control member, a pair of bars, each connected to a dool and converging to andconnected with the swingable end of said member, a rope or .cableconnected to the swingable end of said member and guided by a pulley located at one side of said bars, and a spring for positioning said n'ieinber,-whereby its outer end and the connected ends of said bars will intersect an imaginary line at their two ex- 'treme movements, said spring adapted to enpand through a partial swing of said member and to contract through the remainder of the swing of said member, when said member is swung either forward or back.

In witness whereof, I have hereunto aiiixed my hand ruary, 1923. 1
