PETER D. GALRNEAU AND WILLIAM S. NEWTON, OF EAST ST. LOUIS, ILLINOIS.

DOOR OPENER AND CLOSER.

Application filed December 13, 1907.

To all whom it may concern: K

Be it known that we, PETER D. GALAR- NEAU and WILLIAM S. NEWTON, citizens of the United States, and residents of East St. Louis, in the county of St. Clair and State of Illinois, have invented new and useful Improvements in Door Openers and Closers, of which the following is a full, clear, and exact description.

This invention is an im rovement in door operators'of a mechanical and simple character for opening and closing the door, and has for an object to provide in a device of this nature a construction embodying a line having two branches, one 0f which is attached directly to the door and the other passing to the door lock and connected therewith in suoli a manner that when the line is pulled the door if locked and closed, will be unlocked and then opened, or if the door be opened, a pull on the line will close it.

A further object of the invention is to provide means for automatically locking and unlocking the door when in open position by the operation of the door operating means.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views Figure 1 is a front elevation of a door with our improvement applied thereto; Fig. 2 is a cross-section on the line 2-2 of Fig. 3, through the latching spindle, looking in the direction of the adjacent door knob, Fig. 3 is a fragmentary edge view of the door, showing the manner in which it is locked in open position; Fig. 4 is a section substantially on the line 4 4 of Fig. 1, looking in the direction of the arrow and showing a bracket and suspended pulley forming a portion of the door operator; Fig. 5 is a sectional plan of a door opening and adjacent wall, showing the position of the parts of our improvement when the door is closed, and Fig. 6 is a similar view showing the position of the parts when the door is open. y

In carrying out our invention we employ a line 5 which leads from some point remote from the door, from which the door is to be At'a point at about the elevation of the top of the door the line 5 passes through an eye or other equivalent device 6, beyond which, it is constructed with two branches 7 and S, the branch 7 passing over Specication of Letters Patent.

Serial No. 406,275.

two sheaves 9 and 10 Xed to the door casing adjacent to the hinged side of the door; the sheave 10 being arranged about the same elevation as the door lock.

To the latching spindle of the door lock is rigidly attached an arm 1l, to the outer end of which is connected the branch 7 of the line 5 after passing over the sheave 10.

The branch 8 of the line 5 after passing over a pulley 14, is directly attached to the door preferably at its top, as illustrated in Fig. 1. The pulley 14, is freely suspended from the outer end of a bracket 15, the said bracket being fixed above the door to the transom or to the door casing, and operating in connection with the pulley 14 to so direct the branch 8 that when the line 5 is pulled the door, if closed, will be opened, or if the door be opened, a like pull on the line will close it. This operation of the device is best understood by reference to Figs. 5 and 6, wherein it is seen that when the door passes under the extremity of the arm 15 or pulley 14, it is in a neutral position, but the momentum acquired by the door at the beginning of its opening or closing movement, carries it beyond the pulley to a fully open or closed position, as the case may be. It is thus seen that by one and the same operation, the door is both opened and closed.

If the device is applied to a door which is closed by a spring or which is so hung as to swing closed under the influence of gravity, we preferably provide in connection with the door opening means, means for automatically locking the door in open position. This we accomplish by attaching to the wall or other xed support, a catch 16 having a hook or an angularly turned end, as shown in Fig. 1. This catch is so located that when the door is opened the arm 11 will pass over the top thereof and will engage with its angularly-turned end, as shown in Figs. 2 and 3, when the line 5 is released thus making it possible to unlock the door, open it, and lock the door in open position by a single operation. When desired to close the door, it is obvious that on drawing on the line 5 sufliciently to carry the arm 11 out of the path of the angularly-turned end of the catch 16, the door will swing to a closed position.

The arrangement and construction of the door fastener while being the preferred embodiment of our invention, may be modified in numerous particulars within the scope of the invention as defined in the claims annexed.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. In combination with a door having a lock, an opener therefor comprising a bracket attached to the door casing above the door and extending outwardly therefrom, a pulley suspended from the outer end 0f said bracket, an arm attached to the latching spindle ofthe lock, and a single line passing to the point from which the door is to be operated having two branches connected together adjacent to the door, one of wh-ich passes over the suspended pulley and is attached to the door, and the other of said branches is connected to said spindle arm.

2. In combination with a door having a lock, an opener therefor comprising a bracket attached to the door casing above the door and extending outwardly therefrom, a pulley suspended from the bracket, an arm fixed to the latching spindle of the lock, sheaves fixed at one side of the door casing, and a line leading to the door having two branches, one for unlatching the door, passing over said sheaves and attached to said arm, and the other for moving the door to and from closed position, passing over said suspended pulley and connected with the door. c

3. In combination with a hinged door having a revoluble latching spindle, an opening and closing device for the door comprising a support arrangedoutwardly from the door intermediate its side edges, a iiexible member attached to a fixed part of the door near the top of the free edge thereof and movably connected with said support, whereby when said member is pulled, that portion of the member between the door and su port will pass through the support as the oor swings toward the support, and the said member will pass through the support in the opposite direction as the door swings ast and from the support, an arm attache to the latching spindle, and a second fiexible member connected to the first mentioned flexible member and to said arm for operating the latching spindle.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
