Application filed February 20, 1915.
To all whom it may concern Be it known that I, DORSEY M. RoBnR'rs, a citizen of the United States, residing at Preston, in the county of Kemper and State of Mississippi, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference beinghad to the accompanying drawings.
My invention relates to looks and particularly to looks of that class in which a pair of tumblers rigidly connected to each other are shiftable into engagement with a bolt to hold it in its projected position or shiftable out of such engagement to permit the bolt to be retracted, and the particular object of my invention is the provision of a very simple lock which may be readily constructed, easily operated with the proper key, and in which when the tumblers are projected, the bolt will be held positively from any reverse motion.
Hy invention is illustrated in the accompanying drawings wherein Figure 1 is a face view of my improved lock with the inner face plate removed; Fig. 2 is a section on the line 2-2 of Fig. 1; and Fig. 3 is a section on the line 33 of Fig. 1.
Referring to these drawings, 2 designates what may be termed the base plate of the lock and 3 the cover plate therefor, these plates being designed to be connected to each other in any suitable manner and to contain between them the locking mechanism. The base plate is longitudinally grooved at 4: and 5 for the reception and guiding of a longitudinally extending bolt 6. This bolt 6 is formed upon one face, preferably upon the upper face, with rack teeth 7 adapted to be engaged by a toothed wheel 8 mounted upon a knob spindle 9. This knob spindle of course projects out on opposite sides of the door and is operatively connected to knobs of any suitable construction whereby it may be rotated by hand. The knob spindle, however, might be a key actuated knob spindle. The edge face of the bolt opposite the teeth 7 is formed at spaced points with the tumbler recesses 10, there being two of these recesses. The base plate 2 is formed with the parallel grooves 11 and 12 which extend at right angles to the groove 5 and within which operate the tumblers 13 and 14:, these tumblers being spaced from each other a definite distance and adapted when projected to engage in the recesses 10 of the bolt 4:. The ends of the tumblers farthest Specification of Letters Patent.

Serial No. 9,691.
away from the bolt 1 are connected by means of a transversely extending yoke piece 15 which may be formed integral with the tumblers if desired, this yoke piece projecting beyond the tumblers and these projecting ends being received in and being guided by recesses 16 formed in the body of the plate 2. The walls of these recesses form stops limiting the movement of the tumblers.
The ends of the tumblers adjacent the bolt 4 are also connected by transverse bar 17 or yoke piece which may, if desired, be formed integral with the tumblers and connecting the yoke pieces or bars 15 and 17 is a rack 18, the inner face of this rack being formed with teeth 19 adapted to be engaged by a toothed gear wheel 20 mounted upon an arbor or spindle 21. One end of this arbor or spindle is disposed in an opening 22 which extends from the interior of the plate 2 to the exterior face thereof and forms a key-hole. The spindle or arbor at its key-hole end is formed many sided for the reception of a key of a suitable form but it will of course be understood that this spindle or arbor might be so formed as to be engaged by a key other than a many sided key. The inner end of the spindle or arbor extends through the base plate 2 and has attached thereto a knob whereby the spindle or arbor may be operated.
The inner face of the plate 2 is so formed as to provide an abutment 23 which forms one side of the tumbler groove 11 and also abuts against the guides the rack 18 and holds this rack in engagement with the toothed wheel 20. An abutment 2 1 is also formed upon the inner face of the plate 2 which forms one side of the groove 12 and acts to guide the corresponding tumbler and also acts as a support for a spring 25 which spring bears against the cross bar 17 and acts to urge the tumblers into a projected position.
The operation of my invention will be obvious from what has gone before. When the bolt is projected, the tumblers 13 and 1 1 are projected by means of the spring 25 into engagement with recesses 10 of the bolt and hold the bolt from retraction. If it is desired to open the door from the inside, the knob upon the spindle 21 is rotated, lifting the tumbler and at the same time the knob on the spindle 9 is rotated to retract the bolt. When the door is closed, the spindle 9 may be again rotated to project the bolt whereupon the tumblers will be automatically projected into engagement with the bolt. If it is desired to open the door from the outside, a key is inserted in the key-hole 22 which will engage with the spindle 21 whereby the spindle may be rotated to lift the tumblers from their engagement with the bolt to permit the bolt to be retracted by the knob.
While I have illustrated what I believe to be the best form of my invention, I do not wish to be limited thereto as it is obvious that many changes might be made without departing from the spirit thereof. My rack is entirely eifective, positive in its operation, and cannot be readily picked for the reason that an instrument cannot be readily inserted through the key-hole 22 and so into engagement with the tumblers because of the fact that the gear wheel 20 is larger than the key-hole 22 and therefore closes this key-hole positively. The spindle 21 can only be rotated by engagement with the proper key.
Having described my invention, what I claim is 1. A look including a base plate, the plate being recessed to provide outwardly extending abutments, the plate being further provided with parallel channels at the outer edges of the abutments, a bolt movable across the plate, tumblers movable within the parallel channels adapted for engagement with the bolt, yoke bars connecting the tumblers, a cross bar connecting the yoke bars, the cross bar being movable along one of the edges of one of the abutments, and means for moving the tumblers into and out of engagement with the bolt.
2. A look including a base plate, the plate being recessed to provide outwardly extending abutments, the plate being further provided with parallel channels at the outer edges of the abutments, a bolt movable across the plate, tumblers movable within the parallel channels adapted for engagement with the bolt, yoke bars connecting the tumblers, a cross bar connecting the yoke b bars, the cross bar being movable along one of the edges of one of the abutments, and a spring engaging the upper edge of the other abutment and normally urging the tumblers into engagement with the bolt.
In testimony whereof I hereunto afiix my signature in the presence. of two witnesses.
