1 ,41 1 92 Patented Se t. 25, 1917;



Application filed April 14, 1917.

To all whom it may concern:

Be it known that I, Lno Bnnnnn, a citi- Zen of the United States, residing at Avon, in the county of Lorain and State of Ohio, have invented certain'new and useful Tm provements in Door-Fasteners, of which the following is a specification.

This invention relates to door fasteners, and it is particularly intended for use on screen. or other light doors, although its use is not limited to any special type of door.

The object of the invention is to provide an improved device which comprises a latch acting on the inside of the door, in combination with a handle on the outer side, the handle serving the purpose of an ordinary door handle, and also for releasing the latch when it is desired to open the door, the same motion effecting both operations.

A further object of the invention is to provide an improved locking device which will prevent the release of the latch.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a vertical section of a door, showing the latch partly in side elevation; and

Fig. 2 is a horizontal section on the line 22 of Fig. l.

Referring specifically to the drawings, 6 indicates the door and 7 the door jamb or casing. Attached to the latter is a keeper 8 having an incline 9 to lift the latch and a shoulder 10 for the latch to engage. These parts are duplicated at each end of the keeper, so that it can be used right or left hand as desired.

The door is mortised as indicated at 11, the mortise having the form of a vertical slot cut through the door stile. A pair of inner and outer face plates 12 and 13 are mounted on the door adjacent the mortise,

and these plates are slotted vertically as in- 1 dicated at 14 and 15.

The latch bar is indicated at 16, and has a hooked end 17 for engaging the keeper, and a knob 18 for lifting it at the inside. This latch bar is flexibly hung or suspended by means of a fiat bent spring 19, the upper end of which is fastened to the inside of the inner face plate 12, above the end of the slot 14, as indicated at 20. The lower end of the spring is bent outwardly to substantial horizontal position, as shown at 21,, and

is soldered or otherwise fixed to the top edge Specification of Letters Patent.

of the latch bar. This suspension is a sort of yielding pivotal suspension, as by flexing the spring the inner edge of the latch bar may be swung up or down to release or engage the keeper. ft is hung by the spring, without the necessity for any pivot pin. The outer end of the latch bar projects across the door and into the slot 15, directly below the toe 22 of a handle 23 which is pivoted at 2 1 on the outer plate. A convenient way of connecting the parts is by two eye bolts 25, the eyes of which receive the pivot 24 and the stems of which extend through the two plates and through the door stile and are provided at their inner ends with nuts 26, thereby serving both to fasten the latch plates on the door and to connect the handle thereto. The length of the bolts is suflicient to permit the application thereof to doors of different thicknesses, so that the special plates do not have to be provided for each door.

To lock the handle against movement I provide a long thumb screw 26 which eX- tends through the lower part of the plates and screws into a hole at 27 in the inner bar of the handle. lVhen this thumb screw is engaged it is obvious that the handle cannot be lifted to release the latch.

In the use of the device, the latch being applied to a door as shown, when the door is closed the hooked end of the latch, riding up the incline 9, will snap behind the shoulder 10 and thereby fasten the door. By pulling up on the handle 23, as in the act of opening the door, it turns on its pivot 24:, and the cam toe 22 hearing down on the outer end of the latch, acts to raise the inner or hooked end, disengaging the same from the keeper and opening the door in one operation.

The parts of the latch can be cheaply constructed and readily assembled by the user at the time the device is applied to a door.

I claim:

1. In a door fastener, a latch arm, a bent spring by which the arm is suspended in position to engage a keeper at one end, and a lever bearing upon the arm and adapted to lift said end. I

2. A door fastener comprising a fixture adapted to be attached to the door, a latch arm having a hooked end, a bent spring attached to the fixture and suspending the arm in position for said end to engage a keeper, and a lever pivoted to the fixture and adapted. to bear on the other end of the arm, to lift and release said hooked end.

8. In a door fastener, 'the combination of a latch on one side of the door a hand lever mounted onthe other side of thedoor and adapted to engage and operate the latch, and a locking device extending through the door and engageable with the lever to lock the same.

4:. In a'door fastener, the combination of a latch projecting at one side of the door,

an operating lever mounted on the opposite side of the door and adapted to engage the latch, and a screw rod extendingthrough the door and adapted to be screwed into the lever to prevent operation thereof.

In testimony whereof, I do aflix my signature in presence of tWo Witnesses.
