Application filed October 30,1897. Serial No. 656,948. (No model.)

To all whom may concern: also provided with a keyway 11, opening out Be itknown that I, I-IYSON BOYLES,acitizen on the Youtside thereof and registering with of the United States, residing at Janelew, in the key-slot in the inner cover-plate. The the county of Lewis and State of West Virrectangular frame is provided with ears 12, 55 5 ginia, have invented a new and useful Lockby means of which it can be firmly secured ing-Bar for Doors, of which the following is to the iloor. a specification. 13 indicates a pin iirmly secured in the din This invention relates to locking-bars for viding-plate and extending through the keydoors, its objeotbeing to provide a simple and slots in the cover-plates. This pin serves as 6o 1o efficient device of this character in which the a pivot on which the har-operating disks, to bars can be operated from either inside or be hereinafter described, are supported and outside the door by means of a key and havalso as a guide for the key which operates the ing automatic devices to lock the bars in disks. The dividing-plateis provided with either of their positions. a vertical slot 14 in the saine vertical plane 65 15 With this object in view the invention conas the lpin 13 and with two oppositely-dissists of theseveral details of construction and posed curved slots 15, concentric with the combination of parts, as will be hereinafter pin 13. fully described, and particularly pointed out 16 and 17 indicate, respectively, the two in the claims. disks, which are arranged on opposite sides of 7o 2o In the drawings, Figure 1 is a side elevathe dividing-plate 8 and centrally perforated tion of a door and door-frame equipped with to fit over the pin 13.

Any arrangement is inclosed in a casing 6, which is partiallylet of wards may be formed on the outer face of into the dooron its innerside,as clearly shown each disk, such as shown at 23 in the drawin Fig. 2. The casing consists of arectanguings, and these wards may be varied on dif- 95 45 lar frame 7, adividing-plate 8, secured within ferent locks, as will be readily understood.

the frame in any suitable manner to divide In order to lock the disks at the extremiit into two substantially equal compartments, ties of their movement, I provide a lockingand cover-plates 9, which are secured to the plate 24, which extends through the slot 14 opposite edges of the frame 7 in any approved in the dividing-plate 8 and across the periph- 10o 5o manner. Each cover-plate is provided with cries of the disks 1G and 17, and the lower a key-slot, (indicated by 10,) and the door is edge of this plate is adapted to seat in the notches 2l. This locking-plate is provided at its upper edge with a slot 25 to receive the dividing-plate S and permit the locking-plate to have vertical movement. Anysuitable devices may be employed to hold the lookingplate in the slot and guide it in its vertical movement, such as pins 2G, which are shown on one side of the plate S in' the drawings, or flanges 27, which are shown on the other side of the plate 8, such devices to be secured to the locking-plate in any suitable manner to engage the opposite faces of the dividingplate. A pair of spring-arms 2S are secured to the locking-plate at cach end thereof, and to the lower end of the arms bars 29 are secured to extend at an angle therefrom in opposite directions. Each of these bars is provided With a lug 30, which projects in the path of travel of the key to be engaged thereby. These lugs are so arranged that the key will engage them just previously to engaging the pins 22, which project outwardly from the disks. Bow-springs 3l are supported in the upper end of the casing on each side of the dividing-plate and engage the upper edge of the locking-plate 24E to normally hold it in engagement with the disks.

Assuming the parts of the locking mechanism to be in position shown in Fig. 8, the locking-bars 4 will be in engagement With the keepers and the door be securely fastened. Assuming now that it is desirable to unlock the bolts from the outside of the door, the key Will be inserted through the keyway ll and the key-slot in thcinner cover-plate and turned to the right. This will cause the key to first engage the lug 30 on the bar 2D, which will have the effect of lifting the lockingplate out of engagement with the notches 2l in the disks on both sides of the dividingplate, and the further movement of the key Will cause it to engage the pin 22 on the disk 16, and just as soon as the disk begins to turn on the pin 13 the key Will pass out of engagement with the lug 30 and the boW- spring Will return the locking-plate into engagement with the periphery of the disks. The disks can now be turned until the pins or rivets 18, which started from one end of the slots l5, will be engaged With the opposite ends of such slots, when the further movement of the disks will be prevented. As soon as the disks stop the other notch 2l will have been brought below the lockingplate S and the latter ivill be forced into it by the action of the 'bow-springs 3l, and the disks Will then be locked against rotary movement until the locking-plate is again released to Without departing from the spirit or sacrificing any of the advantages of this invention. Y
