6 Claims.

The present invention relates to closure fasteners, and more particularly to door latches adaptable for use with either right-hand or left-hand doors.

Latches of the character referred to are generally not interchangeable for use on either righthand or left-hand doors, which necessitates the carrying of a large stock of both types by jobbers, contractors, etc. Heretofore in the art attempts have been made to provide a latch which would be interchangeable for use on either right or lefthand doors, but the devices of the prior art have not been entirely satisfactory, either because they were too expensive to manufacture, would not 5 stand up in service, or were objectionable in ap-' pearance, etc. The object of the present invention is the provision of a novel latch readily adaptable for use on either right or left-hand doors, which will be rugged and simple in construction, comprise a minimum of parts, and be inexpensive to manufacture, etc.

The invention resides in certain novel features, details of construction, and combinations and arrangements of parts, and further objects and advantages thereof will be apparent to those skilled in the art to which it pertains from the following description of the preferred embodiment of the invention described with reference to the accompanying drawing, in which Fig. 1 is a front elevation of a latch embodying the present invention applied to a right-hand door;

Fig. 2 is a front elevation of the latch shown in Fig. l but applied to a left-hand door;

35 Fig. 3 is a section on the line 3-3 of Fig. 4;

Fig. 4 is a side elevation of the latch shown in Fig. l, as viewed from the right;

Fig. 5 is a perspective view of the keeper for the latch;

Fig. 6 is a perspective view of the base member; Fig. 7 is a perspective view of the latch lever;

Fig. 8 is a perspective view of the latch bolt;

Fig. 9 is a perspective view of the pivot screw; and

Fig. 10 is a section similar to Fig. 3 but showing a modified construction of latch lever.

Similar reference characters designate corresponding parts throughout the several figures of the drawing.

According to the provision of the present invention the latch bolt is removably supported in the latch lever and adapted to be projected therefrom in either direction to adapt the same for use on either right or left-hand doors. With the ex- 55 ception of the removable latch bolt the number of parts employed is no greater than that of the conventional latch of the same type known to the prior art, and when the latch is assembled for either right or left-hand doors, the parts are securely held together in a simple convenient man- '5 ner.

In the preferred embodiment of the invention shown, the latch lever I0 is pivotally supported between two upstanding lugs II and I2 on a base member l3 on a pintle pincarried by the lugs H and [2, which projects-through a pintle aperture M in the latch lever. In the present instance the pintle pin comprises a screw I5 threaded into aligned apertures l6 and I1 in the lugs l I and I2, respectively, for ease of assembly etc. 15 The latch bolt 2| comprises a cylindrical member provided with a head member 22 preferably formed integral therewith but which may be formed separate and attached thereto if desired. The cylindrical member of the latch bolt is adapted to be projected through an aperture 23 in the latch lever either toward the left, as shown in Fig. 1, to adapt the latch for use with right hand doors, or toward the right, as shown in Fig. 2, to adapt the same for use with left-hand doors.

The aperture 23 in the latch lever is spaced from the pintle aperture l4 through which the pintle screw I5 projects and the head member 22, which projects in one direction a considerable distance to one side of the cylindrical member, is provided with an aperture 24 adapted to align with the pintle aperture I 4 when the latch bolt is assembled with the latch lever. In assembling the latch lever with the base member, the aperture 24 in the head member 22 is aligned with the aperture I4 and the pintle screw projected through the two aligned apertures with a portion of the head member 22 positioned or projecting between the latch lever and the projection II or l2, depending upon whether the latch bolt is projected toward the left or right.

The keeper for the latch bolt comprises a base member 25 from which projects a Y-shaped keeper head 26 provided with a notch 21 which cooperates with the latch bolt 2| carried by the 45 latch lever. The keeper head 26 may be formed integral with or may be attached to the base 25, as desired. In closing, the latch bolt 2| rides over a cam surface 28 on the upper side of the lower prong 29 of the keeper head which permits the door to be easily closed, and a cam surface 30 on the under side of the upper prong 3| of the keeper head assures the catching of the bolt in the notch 21 irrespective of the speed with which the door is closed. While the keeper illustrated comprises a Y-shaped keeper head it will be apparent that any well known type of keeper may be employed.

Fig. 1 shows the latch applied to a right-hand door 35, that is, a door which is hinged at the right-hand side. The base members I3 and 25 are secured to the door 35 and a jamb 36 respectively by screws 37 in a conventional manner. The latch bolt projects to the left and the head member 22 is positioned or projects between the latch lever and the upstanding projection I2 on the base member I3. When the latch is applied to left-hand doors, as shown in Fig. 2, where the reference characters 38 designates a door hinged at its left-hand side and the reference character 39 the jamb, the latch bolt 2| is projected through the aperture 23 in the latch lever in the opposite direction, that is, toward the right, in which event the head member 22 is confined between the latch lever and the upstanding projection II on the base member I3. The latch lever illustrated is so shaped that a portion 49 thereof strikes a base member I3 and limits the rotation of the handle portion of the lever towards the member or door to which it is attached.

In the preferred embodiment illustrated, the latch lever is slightly narrower than the distance between the upstanding projections II and I2 and the head member 22 is visible in the plan view. But, if desired, it will be apparent that an overlying ridge may be formed on the latch lever to conceal the underlying head member 22 or a recess in the nature of a counterbore can be formed in the sides of the latch lever to receive the head member. This latter construction is shown in Fig. 10 wherein the corresponding parts of the latch are designated by the same reference characters with a prime mark affixed thereto. The width of the member Iii as shown in this figure is equal to the distance between the upstanding projections II- and I2 on the base member I3 and the head member 22' on the latch bolt is located in one of two similar counterbores 4| on opposite sides of the latch lever I0 so that it is flush with the side of the latch lever.

While the preferred embodiment of the invention has been illustrated and described I do not wish to be limited to the particular construction shown, which may be varied within the scope of this invention. This application is intended to cover all adaptations and modifications of the present invention that come within the practice of those skilled in the art to which it pertains and I particularly point out and claim as my invention the following:
