13 Claims.

This invention relates to improvements in looks and more particularly to improvements in looks combining key and permutation operating mechanism.

An object of the present invention is to provide a new look mechanism wherein key operated parts and permutation operated parts have bolt actuating mechanisms substantially concentric.

Another object of the invention is to provide alock mechanism inwhich a bolt operating part extends beyond the end of the casing to operate a bolt, such part being actuated either by key controlled mechanism or by permutation controlled mechanism.

Another object of the invention is to provide in a lock of the foregoing character concentrically arranged parts for cooperation with a bolt, such parts being respectively key and permutation controlled.

A further object of the invention is to provide new, simple and eflicient permutation mechanism combined with a key operated lock of the tumbler pi'n type for alternative use.

A still further object of the invention is to provide a lock in which permutation mechais located for movement concentric with the core of the lock, which in turn has key operated mechanism eccentrically arranged therein, both the key operated mechanism and the permutation mechanism having concentric bolt operating portions.

Referrin to the drawings and particularly to Figs. 1 to 5' inclusive, I0 indicates a metallic core member of the type commonly employed in looks utilizing pin tumbler arrangements. This core is of substantially cylindrical form for the main part thereof and has an eccentrically disposed counterbore'd through opening I l therein for the reception of a flanged cylinder I21 The cylinder I'2 has a keyway extending thereinto and has a plurality of openings I 4 in the periphery" thereof and extending radially thereof for the reception of the usual pins I5. The'core" l6 hasaplurality of openings l6 aligned under: certainv conditions with the openings [4 and having complemen'tarypins' ll therein normally forced toward the cylinder 42 by springs I BC retained inplac'e by a keeper l9. This much of the lock is a conventional form and requires no further illustration or description.

The core H] has a plurality of peripheral grooves therein in which are frictionally seated split spring ring members 20 21, and 22. These rings are of similar constructionbeing so formed that a; relatively Wide gap exists between the endparts thereof as shown in Fig. 6; the ring 2 thereof being shown in fragmentary form with a gap 2w between its end parts. Each of the rings 20 21, and 22' has a groove 25 extending therearound and having a boundary flange so notched with oppositely disposed notches as to provide a plurality of upstanding shoulder parts 26. The space between adjacent shoulder parts is of such width as to receive one of the fingers 21 extending from each side of the end of a spring member 28 which is wide enough to fit in'to the groove cut in the surface (i-f a ring} The'spri'ng 28 shown in Fig. 7 is illustrated as having fingers?! at each end thereof, but such spring 28 is utilized only on the ring 22' with other springs 28" on rings 26 and 2 5 having: fingers 27" at one end thereof only. The purpose of these parts will be explained later;

The core HI-h'asa recess 38 formed therein and extending from near the front end of the core the: remainder of the full length thereof. The mouth of thisrec'ess 39 as shown in Fig. 5 is of "a'width corresponding substantially to the gap 24 between the ends of either of the rings 20, 2|, or 22. A trip member 3| preferably formed from sheet metal is mounted in the recess 36. The lower edge of the trip member 3| is rolled into substantially a complete tube with extensions 32 and 34 at the ends thereof. A part of the trip 3| also has its edge portion rolled as at 35 and a tongue 36 is struck from the body of the member intermediate its ends. The trip is provided with a lever portion 31 near one end of the body part thereof. The extensions 32 and 34 are provided to mount the trip for limited rotary movement, the extension 34 fitting in a suitable opening in the front part of the core While the extension 32 fits in an opening in the bottom wall of a housing shell to be described later. A spring 38 has one end seated in a suitable enlargement in the bottom of the recess 30 while the other end engages the tongue 36 to normally force the trip 3| upwardly as shown in Fig. 5.

The permutation operating member comprises a sleeve 46 which fits around the core |0 mak ing a snug fit with the flange It) at the front end of this core. The forward end of the sleeve 40 is enlarged as at 4| with the inner surface thereof sloped outwardly as at 42 to provide a surface on which numerals (Fig. 4) can be located in a readily visible position. The opposite end of the sleeve 40 has an inwardly extending annular shoulder part or partition wall 44, the inner surface of which fits against a step cut in the periphery of the core ID. A tab or lug 45 is struck from the body of the shell adjacent the partition 44.

A gear ring 46 is positioned with one side thereof resting against a side of the partition 44 and with the inner edge thereof fitting in a cut-out part of the core Ill. The ring 46 has a plurality of teeth 41 cut in the inner surface thereof and extending over a part of the length of the ring. As shown in Fig. 2, the ring 46 is not a complete ring but has its ends separated a distance sufiicient to permit the mounting between these ends of a dog 48. One end of the dog 48 is rounded as at 49 to fit in a suitable recess in one end of the ring. A part of the dog is cut away to provide a recess 50 into which the upper end of the member 31 of trip 3| can extend. The upper surface of the dog 46 has substantially the same curvature as the ring 46 but is provided with an extension 5|, one end of which is square as at 52 and the other end of which is sloped as at 53. An opening 494' in the wall of member 49 is of size to receive the extension 5| under certain conditions.

The parts previously described are held in assembly in the manner set forth and further by the aid of a shell member 55 which is of general cup shape and which is secured to the core by a screw 56 passing through the bottom of the cup member 55 into a threaded aperture in the core. This bottom also has apertures therein aligned with threaded apertures in the core for the reception of bolt members 51 utilized in securing the lock structure in place in a door or other support. The bottom also has an opening therein for the reception of the extension 32 of the trip 3| before mentioned.

The lock actuating mechanisms associated with this device are shown in Fig. 3. The cylinder l2 has the end thereof so shaped as to provide two substantially wedge shaped fingers 58 in diametrically opposite disposition. In connection with these fingers, use is made of a blade member 59, the side edges of which are substantially stepped to have a part 66 of one width, 9. part 6| slightly wider, and an end part 62 still wider. The end part 62 is shaped in such fashion as to extend diametrically across the end of the cylinder l2 in contact with edges of the fingers 58. Also use is made of a gear member 64 which has a gear sector 65 in the periphery thereof and which has a through opening 66 with wedge shaped fingers 61 in diametrically opposite disposition extending into the opening. This opening 66 is of such dimensions that it can fit around the part 6| of the blade 59, and is of such diameter that the teeth 65 can engage the teeth 41 of the ring 46. Due to the increased width of a part 62 of blade 59 it follows that when the member 64 has been properly positioned on the blade, this part 62 cannot be withdrawn through the opening 66 of member 64. Thus, the parts can be assembled with the end part 62 of blade 59 in position against the end of cylinder I2 and then the member 64 positioned immediately against the end surfaces of the fingers 58. The excess of part 6| and the end part of the blade can extend through an opening in the bottom of the cup shell 55.

The operation and use of this look mechanism are substantially as follows: With the parts assembled relative to the core, the permutation sleeve and the casing shell, such parts assume the relative position in Figs. 1, 2, and 5. Assuming that use is to be made of the key K for operating the lock, the key can be introduced into the cylinder l2 and this cylinder rotated in the fashion customary with locks employing pin tumblers as shown, When the cylinder I2 is rotated counterclockwise, the members 58 bear against the end of the blade 56 and cause this blade to rotate with the cylinder as a unit. During this type of operation one Or more of the rings 26, 2|, and 22 have parts extending across the mouth of recess 39, thereby depressing trip 3|, and consequently dog 48 through lever 31, so that gear member 64 and ring 46 can be moved along with the blade if required.

If the permutation part of the mechanism is to be used instead of the key, the sleeve 46 can be rotated first in one direction and then in another to set the parts associated therewith into such position that they can actuate the blade 59. For this reason, the rings 26, 2|, and 22 fit in their respective grooves in the periphery of the core with sufficient friction to insure each ring remaining in any position, to which it is moved by the proper selective mechanism, after this mechanism has released contact therewith. For example, in one set-up of the permutation mechanism, the sleeve 49 is rotated counter-clockwise first so that tab or lug 45 picks up one of the fingers 21 on the spring 28 engaged with ring 22. This counterclockwise rotation is continued until one of the opposite'fingers 2'! on spring 28 engages a finger 21 on the spring associated with ring 2| and further until the opposite finger 27 on this same spring picks up finger 2'! on the spring associated with the ring 26. The operator, knowing the combination necessary to operate this permutation mechanism, continues the counterclockwise rotation of the sleeve 46 until the first number of the combination has been reached (with the proper number of turns) at which time the gap 24 between the ends of the spring 26 will be in register with the mouth of recess 36 in the core. The sleeve 49 is then rotated clockkwise. v en o i vme ll c hem auses the lug 45 to pick up finger 2l first engaged and n inue m m nt n:.; h s: di ecti n; to; th third numb r: of these 'ne i n. rinssz beiean lseintmah m;
