UNITED STATES PATEN E 1 WILLIAM H. REYNOLDS, OF TOLEDO, OHIO, ASSIGNOR TO THE MEILINK MANUFAC- TURING COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.

LOCKING DEVICE FOR SAFES, 850.

To all whom it may concern:

Be it known that I, WILLIAM H. REY- NOLDS, a citizen of the United States, residing at Toledo, Lucas county, Ohio, have invented new and useful Locking Devices for Safes, &c., of which the following is a specification.

This invention relates to holding devices, and more particularly to forms of bolt throw mechanisms and the means for operating such mechanisms for locks.

This invention has utility when embodied in a lock for safes.

Referring to the drawings: Figure 1 is a rear elevation, with parts broken away of an embodiment of the invention in a lock for a safe; and Fig. 2 is a side elevation, partially broken away, of the structure shown in Fig. 1.

Abutting the rim or stop 1 is the flange 2 overlapping the mounting plate 3. The flange 2 is integral with the outer or finishing plate a which has the annular rib 5. Centrally disposed as to these door plates 3, 4c, is the spindle 6, having loosely mounted thereon the disks or tumblers 7, 8, 9. The tumbler 9 may be locked at various adjustments to the spindle 6 by means of a screw carried by the arm 10, which arm 10 is fixed to the spindle 6. This screw carried by the arm 10 may engage with some one of the holes 11 in the tumbler 9. Protrnding from the disk or tumbler 9 on the side toward the door is the pin 12, which may have any selected location. In the line of travel of the pin 12 of disk 9, is the pin 13 extending through intermediate disk 8, the portion of which pin 13 not on the side engaged by pin 12, is in the line of travel of pin 14 projecting from the disk 7, which pin 1d has a selected location in said disk in accordance with the combination chosen. The changes in position which may be made of pins 12, 13, 14, permits of a wide range in the number of possible combinations. The disks 7, 8, have radially disposed notches 15, while disk 9 has the notch 16 into which the pawl or dog 17 may engage when the disks are so arranged as to bring the notches 15 and 16 in position adjacent this pawl or dog 17 The spiral spring 18 surrounding the pivot mounting 19 of the pawl 17 serves to keep this dog against the peripheries of the tumblers. The pivot 19 for the pawl 17 is carried by the pawl car- Specification of Letters Patent.

rier or cam plate 20 loosely mounted concentric with the spindle 6. This bolt actuating or bolt engaging cam plate 20 mounted on the pivot or spindle 6 has a plurality of cam slots 21 therein, engaged by the screw pins mounted in the forked ends of the radially reciprocable locking devices or holding bolts 22, guided by bolt engaging guides or brackets 23 carried by the mounting plate 3 of the door. Concentric with the circular door and shielding the locking mechanism is the housing 2% having lugs 25, through which screws 26 extend to firmly mount the housing on the door, by engaging in holes 27 in the plate 3. Openings 28 are provided in the housing 24:, for the bolts 22. The bolts 22 on being thrown radially outward by the cam slots 21, with the door in position against one side of the stop 1, co-act with the opposite side of the stop, serving as an efiectual holding device.

The showing in Fig. 1, is with the pawl 17 dropped, so that a slight further turn of the spindle 6 will withdraw the thrown bolts. This turning of the spindle 6 to withdraw the bolts would move the pawl 17 to the left in Fig. 1. A movement of the spindle 6 to the right, would cause the bevel of notch 16 to actuate the pawl 17 outward, while rod bracket 23, the one of the bolt engaging devices adjacent the pawl provides a stop to limit the outward throw of the pawl. The pawl in this outward position rides on the peripheries of the tumblers and permits the combination to be thrown off by further rotation of the spindle 6 to the right in order that the pins 12, 13, 14, may disarrange the grouping of the tumblers. As usual in combination locks, the spindle is twirled one direction more times than there are tumblers, and then alternately in opposite directions in accordance with the combination to line up the notches of the tumblers for the pawl 17.

The combination herein disclosed of a lock, illustrated as of the permutation type, with a bolt throw holding scheme, is compact, substantial, and has the further advantage of requiring but one hole through the door through which the lock may be operated as well as the bolts thrown. The arrangement of the bolts and their mounting is such that they may be thrown simultaneously in a plurality of directions by rotation of the permutation lock spindle. The

pawl which serves to connect the lock spindle I ing bolts for the door, a spindle rotatably to the bolt throw plate, travels concentrically with the spindle to perform this function. In mounting the movable pawl on the door, it is not necessary to always have the pawl above, or in any other fixed relation as to the spindle, so there is no clue to guide a safe-breaker as to the point which door should be drilled to locate the pawl. The spindle 6, rotatable relatively to the door, may operate the permutation lock and then automatically operatively connect through the tumblers and pawl with the cam plate to throw or withdraw the holding bolts.

hat is claimed and it is desired to secure by Letters Patent is:

l. The combination with a round door of a permutation lock comprising a pawl, a spindle rotatably mounted in said door, radial locking bolts for said door, opcratively connecting means for actuating said bolts through said pawl including a mounting member for the pawl concentric with the spindle, and bolt engaging guides holding said door against rotation relatively to the bolts.

2. The combination with a round door, of radial locking bolts for the door, a spindle rotatably mounted in the door, bolt engaging guides holding said door against rotation relatively to the bolts, and means operable to connect the spindle to the bolts including a bolt actuating plate, a pawl, and a mounting member for the pawl movable concentrically with the spindle.

3. The combination with a door, of locking bolts for the door, a spindle rotatably mounted in said door, and means operable to connect the spindle to the bolts including a cam plate engaging the bolts, tumblers mounted on the spindle and actuable therefrom, and a pawl mounted on said plate and connecting the tumblers to the plate, whereby the spindle may 'e connected to and disconnected trom the bolts.

i. The combination with a door, locking bolts for the door, and bolt engaging guides holding the door against rotation relatively to the bolts, of a spindle rotatably mounted in said door and means for connecting and disconnecting the spindle to the bolts, said means comprising a plate for actuating the bolts, a pawl mounted on said plate, and tumblers connected to the spindle and operable therefrom to move the pawl.

(3. The combination with a spindle, a door, locking bolts for the door, and bolt engaging guides holding said door against rotation relatively to the bolts, of means for throwing said bolts by rotation of said spindle relatively to the door, said means comprising a pawl, a slotted mounting member for the pawl, said member being provided with a pivot bearing to permit oscillation, there being a connection between the member and bolts through the slotted portion (if the member, and tui'nblers actuable from the spindle to connect the spindle to the pawl.

7. The combination with a round door of radially movable locking bolts for the door, a spindle rotatable relatively to said door, permutation tumbler mechanism operable from said spindle, and connecting means between the mechanism and bolts whereby rotation of the spindle may withdraw the bolts, said means including a rotatable plate mounted on the spindle and connected to the bolts.

8. The combination with a rotatable spindle of radially movable bolts, of means for operating the bolts from the spindle, said means including a pawl carrier and tumbler mounted on the spindle, and a pawl movable to connect the carrier and tumbler, said carrier connected to the bolts, and said tumbler connected to the spindle.

9. The combination with a door of a plurality of bolts, a spindle rotatably mounted in said door, and means for actuating the bolts from the spindle, said means including a cam plate engaging the bolts and permutation lock mechanism operable to connect the spindle to the cam plate.

In testin'lony whereof I hereunto set my hand in the presence of two witnesses.
