DOOR-LOCKING APIPARATUS.

Specification of Letters Patent.

Application filed. September 21, 1918. Serial No. 255,105.

- To all whom it may concern:

Be it known that I, ALBERT PETER, a citizen of the United States, residing at Kingston, in the county of Tuscola and State of Michigan, have invented certain new and useful Improvements in Door-Locking Apparatus, of which the following is a specificaillustrated in the accompanying drawings,

specifically described in the following specification and more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a view in front elevation of a cabinet or structure equipped with my looking apparatus, while i Fig. 2 is a vertical, sectional'view taken on line 22 of Fig. 1.

Fig. 3 is a horizontal, sectional view taken on line 33 of Fig. 2.

Fig. 4 is a fragmentary, perspective view of the apparatus.

Fig. 5 is an enlarged, vertical sectional View of the apparatus.

Fig. 6 is a view in side elevation of the manipulating handle or control and the cooperating parts associated therewith, the parts shown in this figure being removed from the frame or cabinet.

Referring to the drawings by numerals, 1 designates the cabinet or frame which is provided with preferably a plurality of pairs of hinged doors 2, 2; each door is provided with the usual knob or grip 3.

Secured across the cabinet 1, and extending across the inner face of each door 2, is a supporting bracket or cleat 4; this bracket 1, in each instance, is preferably placed near the upper end of the upper doors and near the lower ends of the lowerdoors, although there is no particular novelty in the location of the brackets 4, whether near the upper or the lower edges of the doors; the object is to place these brackets 4 out of the way so that when the doors 2 are open the brackets will not interfere with the storing of articles or goods in the compartment or Spaces behind the door or doors.

Arranged transversely of the brackets 4 are auxiliary brackets 5 (Fig. 3); and in these brackets 5 are rotatably mounted shafts '6, preferably square in cross section, and to these shafts are connected substantially U- shaped hook devices 7. Each hook device 7 comprises a body, of substantially U-shape, as stated, terminating at its ends in eyes 8, which surround shaft 6. The hook device 7 is fixedly secured to the shaft by reason of the bore of each eye being square and fitting snugly over the shaft 6 so that when a rotary movement is imparted to shaft 6, the hook devices 7 will be moved for either looking or,

unlocking the doors 2, as hereinafter described.

On each door 2 is a catch 9, of any ordinary type, which will ride over the hook device 7, and when the devices 7 are raised,

as shown in Fig. 5, the hooks 9 will securely retain the doors in a closed, locked position, but when the square shafts 6 are rotated so as to swing the hook devices 7 Fatented Dec. 1'7, 1918.

downwardly, as shown in dotted lines in Fig.-'-

. 5, the catches 9 will be released, and by the operator grasping the knobs 3, the doors can be opened.

' A central strip 10 carries a rotatably mounted disk 11, and to this disk 11 is secured a grip or angle plate 12, and pivotally mounted at 13, upon the disk 11, are the inner ends of links 14, the outer ends of the links being pivotally connected at 15, to arms 16, that have eyes 17 formed upon their outer ends, which eyes 17 have square bores that fit snugly over the square shafts 6, Fig, 6. When the grip 12 is closed against the strip 10, Fig. 2, the hook devices 7 will be in a raised position, Fig. 5, and as each door is closed the catch 9, carried thereby, will ride over the hook device and will secure the door closed until the operator swings the grip 12 upwardly to the position shown by dotted lines in Fig. 5, whereupon the catches 9 will be released, by reason of the hook devices being then in their lowest position, shown by dotted lines.

The grip 12 is provided with an elongated aperture 18, that permits the staple 19 to ratus whereby a number of doors ,or gates can be locked by a single operator, and such is desirable in storehouses, or in refrigerator plants, or by covering the catches so that a criminal cannot tamperwith the same my device may be readily adaptable to a prison or jail.

What I claim is:

1, In an apparatus of the class described,

the combination with a frame provided with a bracket, a door carried by said-frame, of a dlsk rotatably mountedupon said frame, a

- grip attached to said disk, a shaft rotatably -mounted upon said bracket, a hook device carried by said shaft, a catch carried by-sa id door andco'operating with said hook device for locking the door in a closed position upon saidframe, and means pivotally connecting said shaft to said disk whereby 'movementimparted to the disk through the grip will placethe hook device in a locked or unlocked position with respect to said catch.

2 In an apparatus of the class described,

the combination of aframe provided with a plurality of sets of-doors, brackets secured transversely across said frame and being positioned contiguous to the ends of the T doors sald frame rovlded at its center \vlth a rotatable 'disk,an angle grip provided with an elongated aperture secured to said disk,

auxiliary brackets secured upon said firstinentioned-brackets, shafts square in cross section, journaled in said auxiliary brackets,

hook devices provided with eyes,said eyes having-square bores: and fitting over said shafts,- catches on said doors adapted toengage said hook devices for retaining the doors in a closed position',ar1ns provided at their outer ends with eyes fitting over the square shafts, and links pivotally connected at their outer ends to said arms and pivotally connected at their inner ends to said disk.

3. In an apparatus of the class described,

i the combination with a frame, a doorcaral-ly connected at its opposite'end to said arm.

4. In an apparatus of the class described, the combination with a frame, of a plurality of pairs of doors upon said frame in the same horizontal plane, a single shaft carried by said frame contiguous to all of said doors, a pair of U-shaped hook devices fixedly secured to said shaft behind the doors, said U-shaped hook devices extending from said shaft toward said doors, a pair of catches secured to each pair of doors and each pair of catches engaging a single hook device, and a manually-controlled operating device secured upon the middle of said frame, between the pairs of doors, and being connected to the shaft for moving the shaft 1 to'locked or unlocked positions.

In testimony whereof I hereunto affix my signature.
