20 Claims.

The present invention has for its general object the provision of a very simple, inexpensive, compact, and efficient combination lock adapted particularly to be used for locking books, handbags, and the like, and zipper closures for the same, and which may be made in larger sizes for all purposes for which combination locks are used.

A particular object of the invention is to pro- Vide a combination lock embodying a series of rotatable disks which is so constructed that none of the operative disks contacts'with another or others thereof, and wherein, furthermore, the proper positioning of the several operative. disks relatively to each other to effect unlocking, cannot be determined by sense of touch, as is true of many of the more conventional locks of this character. 1

Another important object of the invention is to so construct the look as to include therein a retially cylindrical and shallow sheet metal casing I, equipped with an extension portion 2 at one point into which the latch bolt 3 may be projected.

The peripheral wall of the casing l is equipped with integral projections 4 which are initially straight and are adapted to pass through a cover ciprocable latch bolt movable manually along a Y diametric line of the housing.

Another object of the invention is to provide a structure of the type specified wherein the operative disks cannot be moved while the latch bolt is disposed in unlatching position.

Other objects of the invention will be pointed out in'or readily understood from the following specification.

A suitable embodiment of the invention is illustrated in the accompanying drawings, where- Fig. 1 is a perspective view of abook equipped with a lock constructed in accordance with the invention.

Fig. 2 is a fragmentary plan view on an enlarged scale showing the lock and the latch member of same, with the latter in released position.

Fig. 3 is a plan sectional view of the lock taken on the line 3--3 of Fig. 13.

Fig. 4 is a fragmentary side elevation of the structure seen substantially from the line 4-4 of Fig. 2.

Figs. 5 and 7 are plan views, respectively, of the fixed ring members of the structure.

Figs. 6, 8 and 9 are plan views showing the rings of the structure which are operative from the exterior of the casing.

Fig. 10 is a plan sectional view taken on the line Ill-40 of Fig. 13.

Figs. 11, 12 and 13 are fragmentary detail sectional radial views taken respectively on the lines l I-- ll, I2--I2 and l3 l3 of Fig. 2.

Fig. 14 is a fragmentary perspective view to constitute a box-like structure.

of a book or wall of ahand bag but which, before being so passed, are bent to the form shown in dottedlines at 5 inFig. 13 to provide offsets therein which underlie and engage the bottom closure plate 6 of the casing l to hold the latter in place, said projections 4 being bent or crimped toward the center of the casing to secure the latter in place. I

The latch bolt 3 constitutes one arm of a substantially Z-shaped sheet metal member which the depth of the casing I while the main arm 8 The arm 3 rests upon the closure plate 6 which includes the extension portion that constitutes the bottom wall of the extension portion 2 of the casing, said portion 2 being peripherally flanged The middle portion 1 of the latch bolt extends throughout the depth of the casing 1 while the main arm 8 of said member lies in contact with the upper wall of the casing I. Said upper wall includes a central offset portion 9 which is provided with a slot through which the shank of an operating button In extends, said shank being rigid with said main arm 8 of said latch bolt. The latter as a whole is referred to hereinafter as the member 8.

The upper wall of the extension 2 of the casing I is offset downwardly from the offset portion 9 of the upper wall of the main portion of the casing l and the same and the portion of the bottom wall 6, which closes said extension 2, are provided with slots II to receive the tongue I2 of the latch member l3 whichis suitably secured to a member M which may be a strap or the slide of a zipper closure. Said tongue I2 is provided with a slot l2a to receive the arm of the plunger 8, as shown in Fig. 13. e

As shown in Fig. 14, the tongue l5of a frame member I6 of a hand bag, or the like, may pass through the extension portion 2 of the casing from the bottom instead of the top.

The offset portion 9 of the casing I is bordered by a marginal shoulder I? which bears three sets of indicia, each set of the same occupying substantially one-third of the arcuate length of said shoulder. The indicia of the several sets may comprise letters of the alphabet or numerals or other characters or devices, but in the instance illustrated, it hasbeen elected to use a set, of equally spaced apart numerals for the set A of indicia which is diametrically opposed to the portion 2 of the casing, and to use letters of the alphabet for the indicia of the sets B and C of indicia disposed on respectively opposite sideportions of the shoulder I'I.

Associated with the respective sets of indicia A, B and C are the operating levers a, b and 0, respectively, by means of which the respective rings I8, I9 and 29 within the casing are actuated, the said rings being shown, respectively, in

Figs. 3 and 6 (ring I8) and in Figs. 8and 9.(rings I9 and 26) .Each of said rings of the same outer diameter as the inner diameter of the lower portion of the casing I.

In assembling the lock, the ring I8 is. first dropped into the then inverted casing. This ring is equipped with two inwardly projecting tongues 2| which are diametrically opposed to each other (see Fig. 3) and are offset toward and to-project into the ofiset portion 9 of the top wall of the casing I (see Figs. 3 and 12). The projections 2| are provided with threaded openings to receive theshanks of set screws 22 (Fig. 12) the-heads of which engage the marginal portion of a ring 23 to clamp the latter against said projections 2| said projection 26 being disposed below the-portionof the shoulder I'I bearing the set-A of indicia.

-Below the ring 25 lies a ring 21 which isintegral with the lever a and is equipped with the radially inwardly extending L-shaped arm'28,

the inner end flange or tongue 29 of which engages in the recess 24 of the ring 23 and which transmits motion to said rings 23 and I8 as described hereinafter.

Below the ring 21 there lies a ring 33' which is substantially identical with the ring 25-except as to location of its arcuate projection 3| relatively to the recess 32 thereof which receives the arm I of a plunger 8 when the latter is retracted from looking position. The ring 25 is equipped with a recess 33 which registers with the recess 32 when both rings 25 and 39 are mounted in the casing I.

Below the ring 3!! lies the ring I 9 equippedwi-th operating arm or lever c and below the ring -I9 lies another ring 34 which is identical'with the ring 39 shown-in'Fig. 7 reversed -'inposition so that the arcuate projection is disposed to theleft of the recess 32.

Thering 29 equipped with operating lever b is disposed betweenthe ring 34 and the bottom plate 6 of the casing.

The ringsyIS, 21, -I9 and "-29 are equipped'with peripheral recesses '35; 36-, 31-, and I 38; respectively,

corresponding in shape and size with the recesses of the several rings 25, 30 and 34 and are adapted to be brought into register therewith by operation of levers a, b and c to permit the plunger 8 to be retracted from looking position. The tongue 3 of said plunger 8 is bordered by guide projections 39 struck up from the plate 6 (Figs. 3, l0 and 13).

The arcuate portion of the peripheral wall of the casing is composed'in part. of arcuate flanges bordering the shoulder I! and in part of arcuate edge flanges of the plate 6, as is illustrated in part in Fig. 4 and in Fig. 3. The latter shows three flanges 40, M and 42 which are of stepped formation and have side edge portions spaced apart'to snugly receive the arcuate projections of the rings 25, 39 and 34 between them.

The arcuate flanges of the plate 6 are disposed in staggered relation to those of the casing referred to as 40, 4| and 42, the relative arrangement ofthe two sets of flanges being such that each of -the=rings 21,19 and 29 may be rotated through predetermined arcs.

Thus the ring 2'1 isrotatable through an are equal to the arcuate length of the-set A of in- 'dicia while the rings l9 and 20 are rotatable only through arcs of a-length such as will prevent the locking recesses thereof from becoming visible through the slots in which the levers b and care rotatable.

'flanges of the casing-I and the plate 6 issuch that only the arcuate projection, such as 26, of the several fixed rings will be visible together with arcuate portions of the rings 21', 'I9and'20 "of a length equal to the lengthofmovement-of the levers a, b and 0, respectively,- -from the exterior of the casing.

Fragmentary portions .of arcuate flanges 4| and42 of the casing and a'fragmentary; part ofv a similar flange of the, plate 6- are shown jin Fig. 4, the portion of the plate 6 to the right of prong 4 of said figure being devoid of an arcuate .flange.

'The length of the recess of the ring-23 which is clamped to the ring I8 (the onlyone .not visible from the exterior of the casing) is appreciably less .thanthe length of arcuate movement'of the lever 'of a ring 21 for reasons hereinafter set forth.

The diameter of the central openingjof all rings, except the ring "I8, is so much larger'than that of the latter, that access to the set screws 22 may be had through the openings 45 in the plate 6, the latter and the ring I8 being also equipped with openings 46 and'4'I'which are in register when thelock recess of ,thering I8 is in register with the lock recesses-of the fixed rings, the said openings 46 and 41 being inward of the circumferential walls of the openings in the fixed rings and the rings 21,19 and20.

Obviously, the positions of the levers b and c with respect to their spacing from the lock recesses of the disks I9 and 20 determine which of the indicia of the sets B and C, respectively said levers must register with to bring said lock recesses intoregistenwith those'of the fixed rings and this can be'variedonly byinterchange of rings l9 and2U,--respectively, withother similar rings wherein the spacing of said levers b and c from the lock recesses of said rings is greater or less than that herein illustrated if it is desired to change the combination.

In the instance illustrated the lock presents.

actually a four point combination which can be changed onlyas to one of the indicia of the entire set to be used in operating the look.

It will be noted that the ring 21 is provided with the peripheral lock recess 36 which is 011.- set slightly from a position diametrically opposite to the projection 29 thereof, which engages in the recess 24 of the ring 23, as shown in Fig. 3, said ring 23 being adjustable relatively to the ring I8., as above described. I

It may be assumed that the levers a, b and c, as shown in Fig. 2, are in the position wherein the lock recesses of the disks 21, I9 and 28 are in register with the lock recesses of the several fixed rings and that the lever a has been previously manipulated to bring the disk I8 into the position shown in Fig. 3, as by having first moved the lever a to the extreme right hand limit of its movement and then. back to register with the graduations 3 of the scale A and having then been moved into register with graduation 7, as shown.

If it is desired to change the combination, the several disks I8, I9, 28 and 21 are brought into the last-described positions and the latch plunger 8 then moved to the position shown in Fig. 3. This holds the opening 41 of the ring I8 in reg ister with the opening 46 of the bottom wall of the casing and a pin, such as a rivet, is then inserted through opening 46 and into opening 41. After this has been done, the latch plunger 8 is projected forward and out of the lock recesses after loosening the screws 22, and then while the said pin or rivet holds the ring I8 against rotation, the lever a is manipulated to throw the ring 23 into a different position relatively to the ring I8 than as shown, for example, in Fig. 3, the efiect of this being to change the position of the recess 24 relatively to the locking recesses of the disk I8. In effecting this adjustment of the ring 23 the lever a is moved in to engagement with either of the two end walls of recess 24 and is then moved farther in the same direction until the position of lever a registers with the selected graduations on scale A. The screws 22 are then tightened to maintain ring 23 in this new position relatively to the ring I8 and thereafter the operation is exactly as previously pointed out.

Obviously, the number of rings such as I9 and 20 may be increased or diminished and suitable changes made in the length of the slots through which their operating levers project, or said disks I9 and 20 may be omitted entirely to reduce the combination to a two-point one, or if only one of the disks I9 or 28 is used, the combination becomes a three-point one, it being an advantage,

of the structure that it may be varied in depth according to the number of movable rings intended to be used, thus adapting the structure to be made very shallow, if desired.

The levers b and c are equipped, preferably, with differently colored knobs or buttons (such as red and blue) while the outer end portion of the lever a is maintained in the same finish (such as nickel plating), as the casing I; said finish being substantially white. Thus the combination may be explained readily by reference to red, white and blue buttons or levers, respectively.

In Fig. 15, there is illustrated a ring 49 which may be substituted'for the ring I8 and which is.

equipped with an arcuate slot 58 and with a lock recess 5|. The projection 29 of the arm 28 of the disk 21 will engage in the arcuate recess 58 to actuate the ring 49 in exactly the same manner as ring I8 is actuated via the ring 23, the latter being omitted, obviously, from the structure.

When the ring 49 is used in place of rings I8 and 23, the combination will not be capable of change, except by replacing the ring 49, as shown, with another ring of the same type wherein the spacing between the lock recess 5| and the arcuate slot 50 is changed.

In ordinary use, as on a womans hand bag, the several levers a, b and 0 may be maintained in the respective positions wherein the plunger 8 is freely operative to lock and unlock the bag, or one of said levers may be moved slightly out of that position so that it can be quickly restored thereto to permit opening of the bag.

While in the instance illustrated, the rings I8 and 21 are shown as disposed immediately below the top wall of the casing, it will be obvious that the same may be disposed at any level within the limits permitted by the depth of the cas- I claim as my invention:
