DOOR OPERATING AND LOCKING DEVICE.

Application filed January 10, 1918.

To all whom it may concern:

Be it known that I, EDWARD J. COLEMAN, a citizen of the United States, residing at Scranton, Pennsylvania, have invented certain new and useful Improvements in Door Operating and Looking Devices, of which the following is a specification, reference being had therein to the accompanying drawmgs.

This invention comprises a door operating and locking device, and While it may be generally applied, it is especially adapted for use in connection with sliding doors and the like.

' It is contemplated among the objects of the invention to provide apparatus of this character which willbe readily applied to a door and preferably within the casing so as to be hidden from view; which will have few parts so arranged that they may be readily assembled; which will permit easy operation of the door to open it, and which will smoothly and positively close and lock it; and which will permit an adjustment of certain parts of the apparatus so as to make it applicable to various sizes of doors, and suitable for use under various working conditions.

Other objects and advantages will be in part apparent, and in part be developed in the description which follows.

Drawings illustrating an embodiment of the invention are hereto appended, the following views being shown:

Figure 1, is a view in side elevation showiing an application of the device to a sliding oor;

Fig. 2, is a similar view, partly broken, and showing the position of the parts when the door is open;

Figs. 3 and 4c are detail views in longitudinal and vertical section respectively of a locln'ng device.

In these drawings, 1 and 2 represent top and bottom sills, joined by uprights or posts 3 to constitute a casing for a door 4. The latter is hung upon hangers 5, provided with rollers which travel on a rail 6 suitably secured as by bolts 7 to the upper sill 1. All of this is well known construction and will not be described in detail.

Adapted to be associated with the construction just described, or with a construction of similar characteristics, is the inven- Specification of Letters Patent.

tion which comprises the subject matter of the present application. As here shown it comprises a supporting member 8 adapted to be located in any convenient manner in association with the door, and here shown as secured to the top and bottom sills as by bolts 9.

This supporting member carries, intermediate its ends, means for mounting a weight, and as here shown such means comprise links 10, mounted at one extremity thereof in pivots 11 attachedto the supporting member, and at their other extremities attached to a weight 12, preferably through hinge or pivot connections 13.

Disposed upon the weight 12 there is a lug or connecting member 1 1, and this works in a slot 15 provided in a link 16. The slot is provided at one end of the link, and its opposite end is connected as by a pivot 17 with a lever member 18. The lever member 18, from its point of connection with the link 16, curves downwardly and then extends in a line approximately parallel with the plane of the door rail, to provide an offset 19. The other extremity of the lever 18 is provided with a handle 20, and preferably at approximately the point where the handle meets the horizontal portion of the lever, it is secured to the door as by a pivotal connection 21.

The handle 20 is arranged at an angle to the horizontal portion of the lever 18 when in the position shown in Fig. l, and a casing 22 is secured to the door in such a position that only a portion of the handle protrudes from the lower portion of the casing, and is adapted to work back and forth in an opening provided in the casing for this purpose.

The casing is provided on its face with openings 23 into which a locking lug 2 1 is adapted to fit, the lug being carried on a spring 25 which is hingedly secured to the casing. The spring permits the lug to drop into the opening to retain the handle at the extremities of its movement to the right of the casing as shown in Fig. 1, or to the left as shown in Fig. 2, and thus lock it positively in either of these positions.

For the purpose of actuating the locking device, a handle 26 is provided thereon.

Secured pivotally as at 27, to the supporting member 8, there is another link 28, the opposite end of this link being curved upwardly as at 29, and secured to a pivot 30 intermediate the ends of the lever 18. lhe portion 29 of the link 28 forms a limit stop for the movement of the lever 18 in a clownward direction when the parts are in the position shown in Fig. 1.

Means are provided for adjusting the movement of the operating lever With relation to the weight and as here shown comprise a plurality of openings 31 in the weight, and in the various ones of which the lug or connecting member let may be placed. Varying the position of the lug in this manner varies the sweep of the lever to meet difierent conditions of usage.

. The operation of the device is as follows: When the parts are in the position shown in Fig. 1, the horizontal portion of the lever 18, and the links 28 and 16 are in approxi mate alinement, and will resist any eli'ort to force the door back to the position shown in Fig. in addition to this the lug of the locking member prevents movement of the handle :20, and the door is securely locked.

By moving the lug 24 out of the opening 23, the handle 20 may be moved to the left, and this movement lifts the links, weight, and extremity of lever 18 from a horizontal position to that shown in Fig. 2'. As the links are fixed to the supporting member, the door will be drawn back, and may be locked in open position by inserting the lug 24 back of the handle as shown in that figure.

From the foregoing it will be apparent that the present invention constitutes a simple and practical means of efiecting the objects herein enumerated, but it will be understood that 1 do not wish to be limited to the exact structure of this disclosure only in so far as set forth in the claims.

What I claim is I l. A door operating device comprising a supporting member adapted to be secured in operative association with a door; a weight pivotally secured to the supporting member; a door operating lever connected to the weight at one end, and to the door at the other end; and a link member connecting the door operating lever and the supporting member.

2. A door operating device comprising a supporting member adapted to be secured in operative association with a door; a Weight connected with the supporting member and having movement in relation thereto a door operating lever connected at one extremity to the weight and at its other extremity to the door; a link member connecting the supporting member and the operating lever; and means for locking the operating lever in a plurality of positions.

3. A door operating device comprising .a supporting member adapted, to be secured in operative association. with a door; a

weight connected with the supportingmernher and movable in relation thereto; a door operating lever. connected at one end to the weight and at its opposite end to the door;

a link member connecting the supporting member and the door operating lever; and means for adjusting the' movement of the operating lever with relation .to the weight.

In testimony whereof 1 hereto affix my signature.
