GEORGE V. SCHATZ, OF REPUBLICAN CITY, NEBRASKA.

SLIDING-DOOR LOCK.

Application led January 18, 1912.

Specification of Letters Patent.

Patented Dec. 3, 1912.

Serial No. 671,944.

To all whom t may concern.' f

Be it known that I, GEORGE V. Soi-IATZ, a citizen of the United States, residing at Republican City, in the county of Harlan, State of Nebraska, have invented certain new and useful Improvements in Sliding- Door Locks; and I do hereby declare' the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cert-ain new and useful improvements in sliding door locks, and has for its object to so construct a device of this character that the lock vbolt will be concealed in the casing when the door is in its open position, thus preventing persons when passing from tearing their garments, and will also prevent the lock bolt from becoming broken by contact with passing objects.

A further object of the invention is to rovide a lock of this type wherein the lock bolt will automatically engage the keeper plate when it is desired to lock the door.

Tith these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

Tn the drawings: Figure 1 is a side elevation of the device, one cover being removed and showing the parts in their locked position. Fig. 2 is a similar view, the parts being shown in their unlocked position. Fig. 3 is a sectional view on line 3#3 of Fig. 2. Fig. 4 is a similar view to Fig. 1, but of a modified form of the invention. Fig. 5 is a similar view to Fig. 2, and of the modified form. Fig. 6 is a sectional view on line 6 6 of Fig. 4. Fig. 7 is a sectional view on line 7-7 of Fig. 2`

Referring to t-he drawings, the numeral 1 designates a rectangular casing and to which are secured the cover plates 2, said plates being connected in any suitable manner. The cover plates 2 are provided near their inner ends with bayonet slots 3, said slots being arranged in registered relation, the purpose of which will appear later.

Adapted for sliding movement within the casing 1 is a lock bolt 4, the inner end of which carries a pin 5, which extends transversely thereof, and has its opposite ends formed with threaded bores 6. Adjust-ably engaging the bore 6 are thumb screws 7, the heads of which are rounded and are adapted to project into the slots 3 for a short distance, thus permitting the. same to be grasped when it is desired to operate the lock bolt 4 to open the door. Short grooves 8 are formed in the inner opposing faces of the cover plates 2, and are arranged in direct alincrnent for receiving the ends of the pivot pin 9 which :passes through the locking bolt 4 intermediate its ends. Thus it will be seen that the locking bolt 4 is not only slidably mounted within the casing 1, but may be rocked upon the pivot pin 9 to perform its proper functions.

Formed near the outer end of the locking bolt 4 is a rectangular recess 10, the saine being adapted to engage the keeper plate 11 upon the curved end of the bolt 4 passing through the opening 12 formed therein. To positively cause the recess 10 to engage the keeper plate 11, a coil spring 13 is provided, the inner end of which is connected to the eXtreme inner end of the locking bolt 4, while the outer end thereof is connected to the casing 1 in any suitable manner. Formed integral with one of the cover plates 2 is an upwardly curved plate 14, and over which the coil spring 13 passes, thus preventing the same from. contacting with the bolt 4.

A pin 15 is passed through the casing 1 and has its opposite ends suitably connected to the cover plates 2, and upon which is pivotally mounted a detent 16, the lower end of which is curved downwardly, as at 17, the upper end of said detent being provided with a projection 18 which is adapted to engage and disengage with a notch 19 formed near the outer end of the locking bolt 4.

Having its outer ends extended a slight distance through a perforation 20 formed in the outer end of the casing 1, is a rod 21, the inner end of which being pivotally connected to the' downwardly curved end of the detent 16. Surrounding the rod 21 is a coil spring 22, one end of which is secured to the inner end of the rod, while the other end is connected to the outer end of the casing 1, said spring serving to hold the projection 18 of the detent in engagement with the notch 19 when the bolt 4 is within the casing or in its unlocked position. Secured in any suitable manner to the keeper plate 11 is a lug 23, and with which the outer end of the rod 21 contacts when the door is moved to its closed position, whereupon said rod forces the curved end of the detent 16 inwardly and upwardly, thus disengaging the projection 18 thereof from the notch 19, and when this occurs the spring 13 will draw the bolt 14 forwardly until the pin 5 l thereon assumes a position as shown in Fig. 2 in the bayonet slots 3, thus permittingy the recess 10 of the bolt 4 to engage the keeper plate 11, and thus holding the door against accidental opening.

The lock is applied to Ithe door in the usual manner, that is to say the same is placed in a mortise, and as doors vary in thickness t-he bolts 7 are adjustably mounted as before stated, so that the locks may be applied to doors of different dimensions.

To release the door it is only necessary that one of the bolts 7 bevgrasped, whereupon the bolt 4 will be rocked upon the pivot pin 9 to. cause disengagement of the recess 10 with lthe keeper plate 11, and upon t-he bolts 7 passing from the outer end of the bayonet slots 3 to the inner ends thereof, the outer end of the bolt 4 will be elevated as the same is drawn within the casing 1, thus permitting the projected end 18 of the detent 16 to hold the bolt 4 within the casing and against the action of the spring 18.

In the modified form of the invention the cover plates 2 are provided with alined keyholes 24 which register with a space 25 formed by upstanding lugs 26, said lugs being an integral part of a slide 27 which is mounted upon the bottom of the casing 27. The innermost lug 26 is slightly greater in height than the other lug and is adapted to limit the downward movement of the bolt 2 8 when it is desired to lock the door against unauthorized entrance, as clearly shown in Fig. 4 of the drawings, and when the depending lug 29 carried by the bolt 28 rests thereon. From this construction it will be seen that upon the key 30 being inserted in one of the key-holes 24, and from either side of the door, the rocking of the same by the ward thereof will move the slide in the desired direct-ion to either lock or unlock the door.

I/Vhat is claimed is:

1. In combination with a casing, having cover plates, grooves formed in said plates,

of a bolt, a pin arranged transversely of the bolt for engaging the grooves to pivotally support the bolt, a detent pivotally mounted in the casing, and means for automatically disengaging the detent with the bolt to permit said bolt to engage thev keeper plate to lock the door.

2. In combination with a casing, having cover plates, grooves formed in said plates, a

transversely arranged pin secured intermediate the ends o-f the bolt for engaging said grooves to support the bolt in the casing, of a bolt, a keeper plate, a detent pivotally mounted in the casing and adapted for engagement with the bolt, a rod having .one end pivotally connected to one end of the detent and its other end projected through the casing, whereby when the projected end of said rod engages the keeper plate the detent will disengage the bolt, thus permitting the same to slide forwardly in the casing to `engage the keeper plate to lock the door, and

means for sliding said bolt forwardly.

3. In combination with a casing having cover plates, of bayonet slots formed in the side plates, grooves formed in the inner opposing faces of the cover plates, a bolt having a transverselyV arranged pin Vsecured intermediate its ends for engaging said grooves, a second pin similarly larranged at the inner end of said bolt, said pin being slidably mounted in the bayonet slots, a coil spring having one end connected to the casing and its other end to the inner end of the bolt, a detent pivotally mounted in the casing, a rod having one end pivotally connected to the lower end of the detent and the other projected thro-ugh the casing for engaging a keeper plate, a coil spring surrounding said rod and having one end secured thereto and the other endv to the casing, whereby when the rod contacts with the keeper plate the detent will be operated to disengage its upper end from the bolt to permit the same to slide in the casing to engage the keeper plate.

In testimony whereof, I alflX my in presence oftwo witnesses.
