LOCK.

To all whom it may concern:

Be it known that I, JoI-IN BLAszozYK, a subject of the Czar of Russia, and a resident of the city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.

The present invention relates to improvements in looks, and more particularly to that class which is termed permutation locks.

One of the objects of the invention is to provide a permutation lock, the general arrangement of which embraces great simplicity, both in construction and manipulation, and offers at the same time ample security and a very great number of possible combinations.

l/Vith these and other objects in view, which will appear as the nature of the invention is better understood, the same con sists in the novel construction, arrangement and combination of parts, hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims, it being understood that various changes in the size, form and construction of the several parts may be made without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a lock embodying the features of the invention, Fig. 2 is a section taken on line 2, 2 of Fig. 1; Fig. 3 a section taken on line 3, 3 of Fig. 2; Fig. 4 is a front elevation of the outer dial plates; Fig. 5 a front elevation of one set of the cooperating tumblers; and Figs. 6 and 7 are plan views of the tumblers illustrated in Fig. 5. Fig. 8 is a front elevation of a modified detail of construction.

In the said drawings, the numeral 10 represents the wall of a safeor other door, or parts upon or in which the lock is mounted. The lock casing is indicated at 11, attached to the inner side of the door in any suitable manner; its front plate being indicated at 12 and the back plate at 13. The casing incloses the locking mechanism, the locking bolt 14 of which protrudes through a hole in the face plate 15, and may be moved by hand from the inside, or by, an actuating lever v Specification of Letters Patent.

from the outside, described.

The dial plate of the lock is shown at 16 and forms part of the cap plate 12. The dial plate is provided with three sets of graduations 17, 18 and 19, of a suitable number. For instance, in the case illustrated, the dial 17 is marked with twelve equal divisions, and the dials l8 and 19 each with sixty, corresponding thus to the hours, minutes and seconds of a clock dial. To the outer side of the door is attached a dial plate 20 graduated in the same manner as the dial plate 16. To each dial corresponds a set of cooperating, independently movable tumblers; more particularly to the three dials 17, 18 and 19 correspond three sets of cooperating tumblers 21, 22 and 20. Each set of tumblers comprises two disks 23 and 24, provided with peripheral flange portions 25 and 26, respectively, which, when engaged with each other, form a casing, as clearly shown in Figs. 2 and 5. In the flange portion 26 and, preferably, at diametrically opposite points are formed recesses 27, 27, adapted to be engaged by projections 28, 28 upon the flange portion 25, fixing thereby the relative positions of the coacting tumbler sets.

The tumbler set 20 is attached to the spindle portions 29 and 30, of which the portion 29 protrudes through an opening in the cap plate 12 of the look, while the portion 30 is provided with a finger 31, engaging a recess 32 in a spindle portion 33, to which is attached a disk 34, resting upon the dial plate 20 and being provided with a knob 35, to rotate the same. The disk 34 is provided with a zero mark 36, for the purpose hereinafter to be described. The tumbler set 20 is arranged within the tumbler set 21, and both sets within the set 22, the disk 23 of which contacts with the inner side of the cap plate 12. The disk 23 of the tumbler set 21 is attached to a sleeve 37, in which the spindle 29 is journaled; said sleeve 37 being journaled in a sleeve 38, attached to the disk 23 of the tumbler set 22. The disks 24 of the tumbler sets'21 and 22 are fastened to sleeves 39 and 40, respectively, arranged in a similar manner with respect to the spindle 30 as the sleeves 37 and 38 of the corresponding disks 23 in relation to the spindle 29. The sleeves 39 and 40 are provided with teeth as will be hereinafter fully 39 and 40 engaging recesses 41 and 42 of sleeve sections 41 and 42, respectively, encircling the spindle section 3.3. A spring 43 is arranged within the tumbler set 20 for a purpose to be described.

To the spindle 29 and the sleeve sections 3.7 and 3.8 are attached hands 45, 44 and 46, in any suitable manner, outside of the ca plate 12 of the lock, and pointing to the g ad ations f he dia s.

The other end of the rod 54 is; bent at right angles to the body thereof, a s w 6 a is e gage by a pr n (58-, attached to a disk 69, resting against the 12 .3456 54 and being provided with an ace tuati-ng lever 70, protruding throngh a slot '11 in the dial plate 20 at the outer side of the door. The rod 54 is guided in its movernent by a bracket 72, attached to the face plate 12] of; the casing, and carries a suitably bent arm 73, extending toward the axis of the spindle section 30 to a point which corresponds to the distance of the outermost point of the secondary tumbler 62 relative to said axis, and in a plane into which the secondary tumbler 62 is shifted when the projections 28 are disengaged from the recesses 27 of the coacting tumbler sets. To the disk 69 is fixedly attached a lever 74, which, when shifted, is adapted to disengage the finger 59 of the actuating lever 57 from the recesses 60 in the lock case.

The operation of the device is as follows: In order to set a certain combination, the

hands 44, 45 and 46 are set to point'to certain numerals upon the three dials 17, 19'

and 18, whereby the projections 28 upon the disks 23 of the tumbler sets are disengaged from their corresponding recesses 27, and set at angular distances relative to each other which correspond to the angular positions of the hands. The disks 24 of the tumbler sets which are held against rotation by friction are thus shifted in the direction of their longitudinal axes toward the plate 64, whereby the secondary tumbler '62 is. brought opposite to the arm 73, preventing thus the retracting of the looking bolt by means of the operating lever 70 from outside. The knob 47 is then screwed up tight, whereby the disks 23- are firmly kept in their respective positions. In closing the door and disengaging by means of the operating lever 70 the projection 5901? the actuating lever 57 from the recess 60, the bolt 14 is projected into its socket and the door thus kept securely closed. It will be observed that the recesses 32, 41 and 42, which are engaged by the teeth 31, 39" and 40, allow the shifting, in the direction of their longitudinal axes, of the disks 24 relative to the non-shiftable spindle 33 and sleeves 41 and 42.

To open the door from outside, first the disk 34 is rotated by means of the knob 35 until its zero mark registers with the numeral 011 the dial plate 20' which corresponds to the numeral to which the handle 44 points upon the dial 17, whereby the projection 48 will shift the lever 49 until the recesses of the tumbler set 21 register with the projections thereof. The disk 34 is then turned in the opposite direction until the zero mark of the disk 34 coincides with the numeral on the dial plate 20 which correi sponds to the numeral to, which the hand 46 points on the dial 18 and finally'the disk 34 is turned until its zero mark registers with the numeral on the dial plate 20 which corresponds to the numeral towhich the hand 45 points on the dial 19, whereby, of course, all recesses. of the tumbler sets register with their corresponding project-ions, allowing thus the leaf spring 63 to' move the secondary tumbler 62, together with all tumbler disks 24 toward the cap plate 12 of the lock, withdrawing thus the secondary tumbler from the path of the arm '73. In shifting now the actuating lever 70, the locking bolt let is withdrawn from its socket, since the said locking bolt is connected by the rod 54 and spring 68 with the disk 69, to which the actuating lever 70 is fastened. Of course, instead of the spring 68, a slotted arm 75 (Fig. 8) may be pivoted at 76 to the rod 54; its slot 77 being engaged by a pin 78, carried by the disk 69.

It will be observed that the spring 48, arranged within the tumbler set 20, serves to prevent the person trying to open the door from feeling the positions to which the disk 34 must be shifted in order to set the combination.

It is to be noted that the disks 23 and the hands 4A, 45 and 46 are moved only when the combination of the lock is to be changed.

What I claim is:

1. In a permutation lock, the combination with a lock case, of a locking bolt slidably arranged therein, a series of normally stationary tumblers, a series of rotatable tumblers adapted to be shifted in the direction of their longitudinal axes and corresponding in number to that of said stationary tumblers, one set of said tumblers being provided with projections and the other with recesses adapted to register with said projections, a secondary tumbler controlled by said rotatable tumblers and normally held in the path of said locking bolt, means for rotating said rotatable set of tumblers to bring said projections and recesses into registering positions, and means for shifting said rotatable tumblers in the direction of their longitudinal axes when said projections register with said recesses and for forcing said secondary tumbler out of the path of said locking bolt.

2. In a permutation lock, the combination with a lock case, of a locking bolt slidably arranged therein, a series of normally stationary tumblers, a series of rotatable tumblers adapted to be shifted in the direction of their longitudinal axes and corresponding in number to that of said stationary tumblers, one set of said tumblers being provided with projections and the other with recesses adapted to register with said projections, a secondary tumbler controlled by said rotatable tumblers and normally held in the path of said locking bolt, means for rotating said rotatable set of tumblers to bring said projections and recesses into registering positions, and means for shifting said rotatable tumblers in the direction of their longitudinal axes when said projections register with said recesses and for forcing simultaneously said secondary tumbler out of the path of said locking bolt.

3. In a permutation lock, the combination with a lock case, of a locking bolt slidably arranged therein, a series of normally stationary tumblers, a series of rotatable tumblers adapted to be shifted in the direction of their longitudinal axes and corresponding in number to that of said stationary 'tumblers, one set of said tumblers being provided with projections and the other with recesses adapted to register with said projec 'tions, a secondary tumbler controlled by said rotatable tumblers and normally held in the path of said locking bolt, means for rotating said rotatable set of tumblers to bring said projections and recesses into registering positions, and a spring for shifting said rotatable tumblers in the direction of their longitudinal axes when said projections register with said recesses and for forcing said secondary tumbler out of the path of said looking bolt.

Signed at New York, in the county of New York and State of New York, this 22nd day of Jan, A. D. 1910.
