PERMUT'ATION-LOCK.

Application filed April 23, 1918.

To all whom it may concern:

Be it known that I, J ULES Mnoii, a citlzen of France, residing at Grasse, Alpes Maritimes, France, have invented certain new and useful Improvements in Permutation- Locks, of which the following is a specification.

My invention relates to improvements in looks, being more particularly an improvement of my patent granted October 2, 1917, Number 1,241,532, and it consists in the constructions, combinations and arrangements herein described and claimed.

An object of my invention is to provide a permutation lock including a casing having a plurality of slidable plates, together with support carrying permutation elements arranged in such manner that they cooperate in obtaining the looking or release of a bolt.

Other objects and advantages'will appear in the following specification, reference being had to the accompanying drawings, in which:

Fig. 15 is a diagrammatic view of parts shown in Fig.14.

It will be observed upon comparison that while the lock structure of this application is alike in some respects to that of my Pat-- ent No. 1,241,532, there are however many lmproved features which have been recently developed and which contribute toward the general efiiciency of the lock.

The lock includes essentially the casing 1 which has a horizontal pair of grooves 2 in the top' and bottom, and a vertical pair of grooves 3 in the side walls. A bolt plate 5 is slidable in the horizontal pair of grooves 2. The bolt plate has a bolt 6 at one side, which is adapted to engage a keeper on the j amb of a door when the look is applied to a door.

7 designates a plate that is vertically slidable on the bolt plate 5, as is clearly shown in Fig. 6, by reference to which it will be seen that the plate 7 includes a sleeve 9 that extends through the front wall of the lock casing 1. A shaft 8 is journaled in the sleeve 9 and extends forwardly through the plate 7, and the inner end 10 of the said shaft 8 is threaded and carries a disk 10 that constitutes a support for the adjustable baffies presently explained.

The disk 11 has an internally threaded hub 12 that engages the threaded end of the shaft 8, as shown, and the said disk includes a flange and a back or rear wall 14, the flange forming the annular wall of a hollow space 13 in which the adjustable baffles mentioned are located, as is best shown in Figs. 5 and 6.

The concentric element supporting rings 15 and 1-6 are supported in the proper relative positions by outer and inner sets of rollers17 and 18 respectively. The outer set of rollers 17 engages an external rib 19 on the outer ring 15, the inner set of rollers 18 engages an internal annular spline 20 on the inner ring 16. Each roller of the two sets is journaled upon a pintle 21 which is firmly seated in the wall 14. The front ends of the pintles 21 are supported in bearings 22. The bearings 22 may consist of separate pieces secured to the front surfaces of the disk 11 and hub 12 respectively, as shown in the drawings, or they may consist of integral parts of'the disk 11.

cated in this tortuous passageand the security of the lock lies in the difficulty of manipulating the support 11 without the latch 29 engaging the. battles;

':The, adjustable baflle's on the outer and "inner rings respectively, are fitted into grooves 80 and These grooves are dovetail in shape, to receive and hold the dovetail shaped .basepo1tions32 of the bafiles. The rear walls of the. grooves30 and 3 1, are formed by key rings 33'and 34 which are screwed in lace. It will be understood that 'th'e indivit ual" sections of the adjustable substantially correct positions, when the key rings arescrewed in place to hold the sections. key rings will eventually bind thesections of said elements. in position.

A pair of pins and 52 arefixed upon the shaft'S, at eithe r side of the disk 11. The pin 51 engages astud 53 on the hub 12, when the disk is in the initial. position shown in Fig. 6. stud .54 on the front of i the disk 11 is adapted to engage the pin 52 when the disk assumes the. second position.

i the latch 29'. The spring '62 'is mounted on stud :W 0l p ojects. inw d y om the mounting for the latch so that a breakage may not result in the event of the latch bements of the plate 7. This is accomplished through a pair of pins 63 on the plate 7,

which project through an opening 64 in the bolt plate 5, and engage horizontal grooves 65 in the bit plate 49. The opening 64 has beveled ways in which the beveled edges 64 of the shaft supporting plate 7 fit.

The positions of the disk 11 during rotations, are traced on a dial 65 on the front of the casing 1, by a pointer 66 on the shaft 8. The dial 65 is graduated in degrees which are suitably numbered so that they'may be more readily followed. The distances in degrees that the pointer 66 is moved over the dial 65, correspond to the distances between the abutment shoulders of the various. permutation elements. The pointer and graduations thus act as guides whereby the operator may know when to raise and lower the disk 11 to avoid contact between said shoulders and the latch 29.

A knurled knob 67 is fixed on the outer end of the shaft 8 so that the shaft may be easily turned. A key 68 on the shaft supporting plate 7, engages an annular groove 69 in the shaft 8. The key 68 prevents the longitudinal movement of the shaft 8, and yet permits it to turn freely in manipulating the combination of the lock.

Bit passages70 and 71 are formed in the outer edges of the rings 15 and 16 respectively. These. passages are normally in alinement, as shown in Fig. 5. They are to be moved into coincidence with the bits 59 and 60, when the disk 11 may be moved over and the bolt 6 retracted. extend radially inward from the passage 71 and they bridge the space 61 between the bits when moving the disk 11 laterally, so that the inner ring 16 may not be turned into said space through an inadvertent turn of the knob 67.

Figs. 14 and-15 illustrate modification of .the lock, wherein a click for following the positions of the disk is embodied. In this form, the shaft 8 is fixed at one end in a plate 87 in turn vertically movable in a supportingplate 88. A screw stud 68 takes the place of the lug 68in Fig. 6, and engages the groove 69, as shown. The plate 87 is held in its elevated positions by the engagement of aserrated keeper 89 on a pendent spring 90, with a dog 91 mounted on the plate 88.

The pulsator consists of a gear and ratchet arrangement 92 associated withan actuating shaft 93. as in my patent dated October 2,

Guards 72 fastened on a screw sleeve 95 which supports the hub of the brake disk 96.

Disks 111 and 111 are secured at'the sides of the brake disk.

Overhanging flanges form parts of these disks, and one of these flanges house the baffles, as shown at the right in Fig. 12. The baflies of the said disk 111 are located on the inner surface and latches 29 and 29 cooper ate with therespective sets of elements.

Mounted upon a bar 97 at one side of the disks 111, is a pair of latch rods 98 which carry the latches 29 and 29 The ends of the bar 97 bear against springs 62 and 62 which provide a mounting with a degree of resiliency. The bar 97 is mounted on the supporting plate 88, substantially as shown. It will be observed that some of the parts shown in Fig. 14 are omitted from Fig. 15. This is for the purpose of defining the relative positions of the latch rods with respect to the permutation elements. The edge of the brake disk is concave so as to more readily hold the brake 40 on the spring 43. The spring 43 is supported by a bar 44 which projects from the plate 88. This form of the lock is operated similarly to the other forms, the shaft 93 forming the means by which the various manipulations are made. It should be observed that the plate 87 includes a square boss 99 which projects through an L shaped slot 100 diagrammatically shown inFig. 15. i The horizontal and vertical portions of this slot accommodate the necessary horizontal and vertical movements of the plate 87 and its associated parts. 7 The operation of the lock is as follows: The first or normal position of the disk11, when the bolt 6 is projected. is that shown in Fig. 6. Here the disk 11 is shown as far back as it will go and from this position, the

disk moves through the successive stages which constitute the required manipulation for unlocking the lock. 29 is out of alinement with the permutation elements 23 et seq on the inside of the rings 15 and 16. The disk 11 engages the arc'uate abutment 45, thus preventing the lateral movement of the parts and the retraction of the bolt 6. The pointer 66 points to 0' on the'dial 65.

- The second stage is reached when the disk 11 assumes the position indicated in Fig. 2. Here it willbe seen, the disk has advanced from the rear wall of the casing 1 and has cleared the arcuate abutment 45. The disk 11 is advanced. to the secondstage by turning the knob 67 through a predetermined number of degrees which is read off the dial 65. The brake 40prevents the rotation of the disk 11 while it advances. During this initial rotation of the shaft 8 through the knob 67, the screw threads 10 The latch caused the disk 11 to advance, the pin 51 leaving" the stud 53. l The stud on the front of the disk engages the pin 52 on the shaft 8 at the end of the second stage. The

latch 29 will also be disposed between the rows of permutation as shown in Fig. 2'.

Although the permutation elements are shown smooth in the principal views of. the drawings, they are actually constructed as shown in Fig. 3. Here certain of thesections of said elements are prosaw teeth.

The final stage is slots 70 and 71 are'in registration with the bits 59- and 60. The bolt plate 5'1nay then be moved-laterally to retract the bolt 6. The gear 56 will also engage the pinion ,577 when thecock 58 may be turned. In conclusion, it should bestated that. there is another p,os-

permutation elements may be arranged according to the words of a familiar qnotation,

, form, obviouslymodifications and changes each word representing an easily remembered' number of degrees of rotation according to the length .of the Word. Thequotation may then be written down, if desired, without attracting the undue attention the notation of an equal number of numerals might excite.
