LATCH DEVICE.

Specification of Letters Patent.

Patented. Feb. 27, 1906.

Application filed March 1, 1905. Serial No. 247,954-

To all whom it may concern.-

Be it known that I, CALEB C. SHIVE, a citizen of the United States, residing at Frederick, in the county of Comanche, Oklahoma Territory, have invented certain new and useful Im rovements in Latch Devices, of which the following is a specification.

This invention rovides a novel form of lock device particu arly designed for doors or the like and embodying oppositely-operating latch-bolts, peculiar means for operating the latch-bolts simultaneously, and special means for adjusting the parts of the device whereby the same is readily adapted for use in connection with doors or similar closures of different sizes.

For a full description of the invention and the advantages thereof and also to acquire a knowledge of the details of constructlon of the means for efiecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without dearting from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings, in which- Figure 1 is a perspective view showing the invention applied. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a cross-section of the actuator.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the invention, referrmg to the drawings, the numeral 1 designates the op ositely-operating latch-bolts, and these bo ts may be arranged vertically of the door or part to which they are applied, so as to be projected above and below the same in effecting a locking action. The projected ends of the bolts are adapted to enter suitable socket-pieces 2, one of which may be seated in the floor and the other attached to the upper portion of the door-frame. It will be understood that the device may be applied and arranged horizontally to the part to which it is secured, this being immaterial so far as the workings of the invention are concerned. The latch-bolts 1 are connected with an actuator 3, arranged between the same and substantially secured to the door in any suitable manner. Connecting-rods 4 are preferably utilized and connect the latch-bolts 1 and the actuator 3, said rods being connected at one end With the actuator, the opposite ends thereof being received in sockets 5, formed at the inner ends of the bolts 1 and detachably secured in these sockets by means of a transverse pin or like member 6, affording pivotal connection between

parts

1 and 4.

The actuator operating the latch-bolts 1 is of a peculiar construction and comprises spaced plates 7, which are mounted upon a journal-pin 8, projecting outwardly from an attaching member 9, which is secured directly to the door or other support by means of fastening-screws or like devices. The pin 8 passes through the plate 7 of the actuator, the inner plate being formed with a boss 10 projecting outwardly therefrom, which boss is of tubular form, so as to receive the pin 8 aforesaid. The boss 10 spaces the plates 7 from each other, having a shoulder 10 to support the outer plate 7, and in order to secure the parts of the actuator together a nut 1 1 is screwed upon the outer end of the pin 8. An operating lever or handle 12 projects laterally from the outer of the plates 7, so as to be readily grasped in effecting movement of the actuator in operating the bolts 1. The spaced plates 7 of the actuator 3 are each provided with a plurality of openings 13 upon opposite sides of the pin 8, and these openings are adapted to receive journals 14 of attaching members 15, which are interposed between the plates 7. The attaching members 15 are two in number and are each provided with transverse openings 16 therethrough to receive the end portion of the rod 4, connected with a certain one of the latch-bolts 1. The rods 4 are adjustable through the openings 16 of the members 15, and set-screws 17, arranged transversely of the members 16, are adapted to engage the rods in order to fix the adjustment thereof with relation to the actuator. The adjustable connection afforded between the rods 4 and the actuator 3 by the provision of the members 15 is such that the rods may be quickly adjusted to adapt the device for doors of different sizes, or, if necessary, the rods may be entirely detached from the latch-bolts 1 and the actuator and other rods of requisite len th substituted therefor. In order that the lever 12 may be ings are provided, and under normal conditions the members are journaled in diag onally opposite openings in the plates 7. When so attached, the lever 12 may be thrown in one direction; but when it is desired to admit of movement of the lever in an opposite direction for the purposes above premised the plates 7 are detached and the attaching members 15 are placed in other of the diagonally o posite openings 13. The movement of the ever 12 is limited in order to prevent the rods 4 from coming into contact with the boss 10, and thus cause straining of the parts, by means of a projection 18, which is pendent from the under side of the lever 12, said projection having its ends formed with curved recesses 19. The ends of the projection 18 are adapted to come into contact with one of the rods 4 when the lever 12 is movable in either direction, and the lever is thus limited in its movement, as above mentioned. To cause the latch-bolts 1 to move in properlyalined positions, each of said latch bolts passes through a guide-plate 20, attached to the door. One or more of the guide-plates 20 may be provided as deemed most suitable, and said plates may be of any size.

The device above described is very simple in its operation, actuation of the lever 12 causing simultaneous movement of the rods 4 in opposite directions when projecting the bolts 1 from the door. The rods 4 are brought into alined position approximately when the bolts 1 are projected from the door, and said rods firmly resist any tendency of the bolts to disengage from the socket members 5 when the lever is in the position indicated. The movement of the rods is exactly the reverse when the lever 12 is actuated to disengage the latch-bolts 1 from the members 5.-

Having thus described the invention, what is claimed as new is 1. In a latch device, the combination of oppositely-operated latch-bolts, an actuator comprising spaced plates, attaching members j ournaled between the plates, rods connected with the latch-bolts and having adj ustable connection with said attaching members, and means for operating the actuator.

2. In a latch device, the combination of oppositely-operating latch-bolts, an actuator comprisin spaced p ates, attaching members j ournaled etween the plates, rods connected with the latch-bolts and having adjustable connection with said attaching members, a lever for operating the actuator, and means for limiting the movement of the actuator relative to the connecting-rods aforesaid.

3. In a latch device, the combination of oppositely-operating latch-bolts provided with sockets at one end, an actuator comprising spaced plates, a journal-pin for the actuator, attaching members journaled between the spaced plates of the actuator and having transverse openings therethrough, rods having one end received in-the socket of each latch-bolt, and an opposite end passed through the transverse opening in an attaching member of the actuator, a set-screw carried by the attaching members for adjusting the connection of the rods therewith, a lever extended from one of the spaced plates of the actuator for operation of the latter, and a projection carried by the lever for limiting the movement thereof.

In testimony whereof I afiix my signature in presence of two witnesses.
