The construction thus far described Fig. 12 is a side elevation partly in cross secwould operate as an ordinary lock by employing tion of the sliding lock block, and holder, v Z the ordinary'key the only difference being'that 1 5 Fig. 13 is a top plan View of the sliding lock I have provided thepinsl3 on eachof thetum 1 block holder, I I Y I blers. I I l I II Fig. 14 is a front and side elevationof the dial, In order .to'prevent a lock, of the type thus Figs. 15 and 16 are perspective views of. two fardescribed, from being picked, I mount upon of the selector rings,
the cy linderS, a dial-1e which is rotatable on this cylinder. Thisdial has an annular groove 16 within which is a key 17 which is adapted to enter one of the recesses 15' formed on the dial selector ring is inserted in the annular groove 'so that the slot 21 is directly behind a letter formed upon the dial face, which letter is to be used in working out the dial combina-' tion. In the present instance; as a matter of illustration, we have used the'word HAM and as the dial selector ring operates the last letter of this wor d, that is, in assembling the lock the 'word must be spelled backwards as"\/iAH, the
slot 2l.will be placed directly behind the letter M or thedial. After being soplaced the dial and selector ring are placed upon the cylinder 5. The next step is toplace uponthe cylinder,
a spacer ring 22'. This spacer ring has inwardly extending lugs"-23[which slide in grooves '24 formed in the side of the barrel,.which lugs prevent rotationof the spacer ring. This spacer ring has a slot 28 similar to the slot 21 and so arranged as ntcoverlie a. groove 27"formed in the top of the'barrel at a point above the pins 13,. The next: step in assembling my lock is to place; upon the cylinder and intermediate selec- . tothe grooves 21 and 26.
tor ring28 which ring has a groove 29 similar I This intermediate ring has indicia forme'diupon its outer surface which indicia is'be'st'illustrated' in Fig. 8, where, it will be noted: that. a star is placeddirectly above the slot 29 and the alphabet is spaced around the periphery. Openings 31 are formed through the selectorring for the receptionoi pins, two pins. being placed on one side of the selector and one pin on the other. To illustrate using theword HAM? the first: pin.30 will be placed one space the letter to be used, that 'is,,as the middle letter, of theword HAM-is A,
the'pin will be placed in the hole in line the letter B. .Always considerthe letters as extending around the periphery in the direction in which the ring is turning; For instance, A is on one'side'of the star and Z is on the opposite side of .the star. If the ring is turning toward the right inliigj 8, then the next spaceto the star is A. However, it" the ring is being turned toe ward the left then the space marked Z must, be considered as A. A second pin .32 is now placed in the ring and spaced one, letter before the next letter to be dialed, as for example, if the last letter tobe dialed is 1-1 then the'second pin will be placed in The ring is now placed upon .fthe cylinder in such apositionthat the slot 29 is'overthe slot 27 of the cylinder. A spacerring is now placed upon the cylinder, which spacer ring is similar to that described as spacer ring 22;} A carrier pin 33 is placed in the opposite side of the ring from the pins 30 and 32 and directly V oppositeithe groove 29, which pin overlies the "spacerringso as to contact similar pins'upon the final selector ring. The final selector rin'g 35 is now placed upon the cylinder and this selector ring carries two pins, one pin 34 is placed in the 'opening'opposite the letter H, the first lete ter'of the word HAM; The second pin 36 is spaced from this first pin one more space than the, number of theletter to be'dialed. For
I instance H, isfto be dialed and H isthe eighth letter in the alphabet, then the second position of Fig. 18.

pin willbe spaced nine spaces or in the Q opening of the ring. A final spacer ring is now placed on the cylinder.
This completes the permutation portion of the lock and in order that. the same may function E slidably position in the barrel 5, a pin 37 having a cam head 38, which cam head abuts acarn surface 39 iormeduponthe sliding lock block 41. This sliding lock block hasapair. of upstanding lugs 42 and 43 and openings 44 therethrough so that the pins 13 may be projected into the lock block when the'lock block is in the position of Fig. 18. This lock block slides upon ablock holder 46 which-block holder has a slot 47 so that the pins 13'rnay be passed therethrough.
A spring 43 is confined between the block 41 and the block holder46. the block holder 46'and adapted to enter a recess 51 formed in the casing .52. I
The result of this last construction is that the sliding lock block and block holder willnorrnally be in the position shown in Fig. 6, the holes 44 A lug 49 is formed upon in the block will be out of alignment with the. pins 13 and the selector rings will lie behind the projections 42 and .43; In this Fig. 5, however, the rings have been turned so that the slots 21, 29 and 40 are in position for the s 'in'ove to unlocking position.
,Now assuming that the lock is readyfor the key andthe key is inserted, the first act of the key will be to shove upwardiy upon the pin 37 with the result that the cam surface 38 acting upon the cam surface as will'push the lock block against the tension of the It will as the key is inserted to its pin 37 will move freely up and down over the succeeding ridges andv'alleys of the key, there being no ridges higher than the first ridge which caused theblock 41 to move to a position, to align the holes 44 withtheir respective pins 13. This spring 48 into thebe here noted that greatest extent, the

barrel as the pins 13 may now move upwardly through the key isrenioved from the barrel the dial is turned "sli htly the selector rings will lie be the openings 44 an d the lock may be actuated in the customary manner. As soon as hind the projections 42 and 43 of the'lcck block and therefore the key cannot again be inserted nor can the lock be picked as the tumblers are i all held downwardly by the pins striking the undersurfa'ce of the lockblcck. Thecasing can- 4 not be removed to find out combination for the reason that the projection 49 heldin the recess 51'by the spring 48,.andcan only be ro moved when the combination has been worked out, which will permit the bloclrholder being In Fig. 6 it will be noted that -the nose cfthe pin 37 is in alignment with the end of the holder 46 and until the pin has raised togthe posit n of Fig! 18, this holder cannot be'znoved and, therefore, the casing is locked until'the combination has been worked "out, after which "thefkey can be inserted thus'raising the pin 37 permitting the holder to be pushed toward the front of the lock through the useof a screw driver or similar instrument, after which .thecasing may beremcved and threadedly disengaged from the cylinder. f V I 7 From the above it will be, evident that the sliding lock block and holder serve to prevent insertion of thekey in the key slot and also serve tolock the casing onto the barrel. Also the sliding lock block and holder cannot be actuated until the selector rings have all been rotated so as to bring their slots 21, 29 and 40 into alignment, thus permitting the lock block to slide so as to bring the openings 44 into'alignment with the pins 13, after which the, key may be inserted to move the lock block and while the key is inserted, the casing may be removed by pressing upon the holder forcing it against the tension of the spring 48, thus permitting a person to remove the casing and the selector rings, for the purpose of changing the pins to different holes in the rings to effect a new combination.
It will thus be seen that I have perfected a lock which will accomplish all of the objects above set forth.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
