Application filed August 5, 1912. vSerial No 713,235.

The. main objects of the invention are to into a` lock opening in a door and to receive y and contain combination devices for oper ating the lock. One end of the casing is formed as a knob shank 2 while thejopposite endis screw threaded, both internally and externally, for purposes to be later disclosed. Upon the exterior screw threads of casing 1 is threaded a cover plate 3 in the outer end of which is slidably mounted the inner end of the shank 4 of the inside knob 5. This knob is formed in twoparts; a body provided with external threads and having Aa large central opening, and a cover or head provided with a similar opening adapted toy be alined therewith and `having internal screw threads. Between the body and head, when assembled, is seated a head 6 formed on a screw threaded rod 7 adapted to be screwed into the threaded bore of the sq'uare end S of an operating shaft 9, the squared end being adapted to fit, slidably, into the corrcspondinffly 4squared interior of the shank 4, for a purpose to be later disclosed. n the shaft 9, near the inside end, is mounte'd a sleeve 10 having two parallel spaced flanges 11 and 12gand provided with two elongated openings 13 arranged diametrically op'posite eachother. A stop pin 14 inovidcd with squared projecting ends 15 is passed through the shaft and the opening 13, allowing limited longitudinal movement of the sleevtl relatively to the shaft. The squared ends 15 are adapted to be drawn through notches ina flange 1G of a holding sleeve 17 and into an annular groove in the inner face or. wall thereof. The sleeve 17 is connected to the casing by screw threads cooperating with the interior threads of the casing. as shown in Fig. 1. This sleeve is provided with an annular liange 18 which spaces it from the sleeve 10. Between the fianges` 18 and 11 a coil spring 19 is arranged. The tendency of this spring is to force the sleeveV 10- and connected parts inwardly of the casing 1.

The inner end of the shaft 9 has a block 20 keyed thereto and Vprovided with a the opposite direction, a. threaded rod 23.

adapted to be screwed into a threaded bore Aof an outer knob cover 24 which is `revoluble on the shank 2., Suchcoupling between the knob cover and shaft causes the shaft to rotate with the knob cover.) By this arrangement, the shaft 9 may be uncoupled "from the knob cover, then rotated one, two,

or three quarters of a turn, or .a whole turn, and again coupled, for purposes to be later disclosed.

From the shaft, and in the same longitudinal line thereon, project a-plurality of pins 25 each playing in a notch or recess 26 in the hub 27 of a combination disk 28"' loosely supported about the 'shaft 9 in the 'bore of a stationary spacing and supporting washer 29 fixed to the interior of the casing by means of a set screw 30 and having about one-half of its circumference cut away `or considerably reduced as at 31, for a purpose to be' later disclosed. .On referring to Figs. 21 to 24 it. will be noticed that,A the notches 26 fin the several disk hubs are of different lengths. -Likewise, thelength of It will belclear thatv rotation of shaft .9v

until and after the pins 25 engage the' walls of notches 26 will cause the combinationv disks to rotate therewith. Likewise, it w'ill be evident that rotation of the knob cover` 24 to cause rotation of shaft 9 will also cause the click spring 34 to travel over the teeth 32 ofthe counting ring 33,A thereby giving a distinct and audible soundfor each separate tooth, so that one may easily count the number-of teeth that the shaft 9 has been rotated in one` or the other direction. In this way a combination may 'be composed for unlocking the door, as will more clearly appear from what follows.

The edge of each disk 28 is provided with a notch 28' adapted to receive a lug 35 projecting from the bottom or inner end of a plunger block 36 slidably mounted in a socket 37 seated `in the door frame and so arranged that its leweropeu end falls directly above a longitudinal opening in the casing 1, thus permitting the lugs to project through the opening and into position to be received` by the notches 28', when these notches have been properly' alined. Normally, the plungerfbloc c 36 is held outwardly or in inoperativeposition by means of supportingspriigs 38 seated in longitudinal bores and resting upon the bottom wall of the socket 37, as clearly shown in Fig. 4.

We will suppose, now, that is-desired its' notch 28 falls into line to 4receive oneof the lugs v35, then the knob cover will be reversely rotated until another of the pins engages the wall of a notch 26 in. another disk and carries thatdisk to such position that lits notch 28-is in position to receive another of the lugs 35 (see Fig."22); then the knob cover 24 will be again rotated' in the first direction until the last pin engages the wall of thenotch of its disk and carries it to such position that its notch 28 is in position .to receive the remaining lug. 35 (see Fig. 23). At this point, all three notches 28'v .will be alined and each will in a'position toV receive one of the lugs'35. Thisvalinernent is shown in Fig. 24.

j', It is necessary, of course, to\have some starting point vfor the combination. This comprises an extra deep notch ai' which causes the slick spring to make a much louder blick than when. falling into the notches ,between the. other teeth. Also; when knb cover 24 is provided with an indei: arrow, the corners of the squared end of and the\opposite ends of lug v21 together with 'the portions of disk 22 atA the sides thereof \are provided. with corresponding numbers. ""flo set one of the many possible combinationsxjfirst turn the knob cover 24 until the click spring dropsinto the notch (giving a louder'click), then turn all of the combination disks as far as possible to the right in Fig. 245,; and then insert the shaft 9, taking care that the\ index number one on the squared end` will fall directly in line With the samenumber on thedisk 22, and with the-arrow. After this assembly is complete screw home the holding sleeve 17, cover plate 3, and threaded rod 7. Now, to operate this combination, turn the cover knob 24 nine clicks counter clockwise (as in Fig. 21), then six clicks clockwise .(as in Fig. 22),and then four clicks counter clockwise again (as in Fig. 23). On thc lirst movement, the pins will engage the walls of their notches 26 successively and cause the `successive disks to travel proportionately tbeyond, whereasgdue to lthe length df' its` slotf.th e first disk. remains undisturbed. Then, byturning again in a counter clockwise direction `tour clicks, the third disk ywill be caught' up and returned until it is in :proper position, as shown in Fig. Q3. To change the combinations it is only necessary to changethe relative positions between the lug 21 and shaft v9. This may be readilyy done;by drawing out the. shaft, turning it one or more quarters of a revolution, and

then coupling again. At each quarter revolution. a different number of the squared end will fall opposite the number one of the lug 21, and for each such rearrangement there will be a known combination, along the same general lines as that above given. Itwill be understood, of course, that the combinations arel worked from the outside by the knob cover 24. The locking members themselves'comprise a. catch block 39 journaled on a pin .4 0 extending through the socket 37 and provided with two shoulders 41 and 42, and two flattened faces 43 and 44; The faces -43 and 44 are adapted to engagesthesplungei;,block 36, and lie in the groove 3G'. Thus, as long as the block 36 is held in the position of Fig. 1 Aand the notches 28 are notI in position to receive the lugs 35, the catch vblock will be solidly locked against turning. In such position the shoulder 41 will be engaged by the straight or abrupt face of a bolt 45 carried by av spring pressed bolt block 46 slidably mounted in a socket 47 adapted to be seated in the door frame and having a grooved bolt plate 48 to guide the catch block as the door is swung shut or opened. The shoulder 42 of the catch block acts simply as a stop. Now, supposing that the combination has been Set to permit unlocking: the operator simply pushes onv the door and the bolt` causes the catch block to turn, forcing the plunger block 36 inwardly until its lugs are seated in the notches Q8. It will be held in this position by engagement of the other flattened surface 43 with the face of plunger block 36. As the door is closed, the opposite face of the notch or shoulder 41 will be enga-ged by the beveled end 49 of the bolt 45, causing the catch block to swing'back to its original position. Should lthe combination become disarranged after the doorv has been opened and before -it is closed again, it is evident that the catch block will not be able to turn when it has met the bolt en-d.

But, the bolt end being beveled, wi'll permit the door to be closed by simply forcing the bolt back within its socket, as will be well understood.

T he door may. be opened andclosed as an,

ordinary door and without usin'gthe combi! 'nation' fromjth'e inside', by 'simplyf drawing the' handle orknob' 4 and its' attached parts outwardly until' the spaces between the disks 1 *28 fall directlyibeneatli 4the lugs 35. T his;

will permit the plungerblock 36 to be forced 2.

Vinwardly for operating thee-.itch block 39,

regardless of the combination, so that Ythe door may be pulled open from the inside. The parts may lbe retained in this position in the manner 'previously disclosed.

The slightly enlarged bore of each .disk 28, together with the stationary supporting washer therefor, completely avoids all possible frictional Contact. between the disk and shaft. Also, each washer is just a shade thickeiI than the hub of its disk, t-o prevent. any possible friction'al contact between one disk andanother, whereby a moving disk would move another in Contact with it..

Preferably, the casing 1 and socket 37 are clamped tightly together by means of clamping bolts 50 passed through a cover -plate 51 and threaded into the oguter wall of the casing. This plate is provided withpairs of depending lugs 52 adapted to engage the outer wall'of the socket 3T at either side'of the lugs 37 having the bearings 38 for the pin 40 ofthe catch block 39.

It is thoughtthat the operationnnd use of the .invention will be clear from the preceding detailed description.
