T- LLZZ wlw-m, it may concern: i

Be it known that I, JOHN SMALLEY CAMP- BELL, a citizen of the United States of America, residing at London, England, have invented certain new and useful Improvements in Locks, of which the following is a specification.

The object of my invention is to produce improvements in locks adaptable to any of the articles to which locks or latches are usually applied-such as boxes, drawers, cabinets, portmanteaus, and bags, aswell as cigarette and cigar cases, purses, and thelikewhich besides being adapted to perform the ordinary functions of a key-lock are alsoprovided with means of ready conversion into an ordinary spring push-fastening.

My invention consists of such members and combinations, as will hereinafter be described in detail in the specification and succinctly set forth in the 4appended claims.

In the accompanying drawings, Figure I is a plan view of one of my locks in a preferred form of embodiment for application to a desk or the like, showing a portion of the springcatch broken awayto exhibit the latch illustrated in the actuating-member-engaging position in full lines and in the disengaging position in dotted lines and also showing in dotted lines the spring-catch swung laterally out of placein the manner provided for manipulation of the actuating member., Fig. II is a section on the line II II of Fig. I. Fig. III is a section on the line III III of Fig. I, showing the key-actuated member of the actuating member in operative position under'manipulation of a key. Fig. IV isa view similar to Fig. III, lsave that theA actuating member is'actuated as a push-fastening, the necessity of the key shown in Fig. 1I being dispensed with by the setting of the-latch into the position illustrated of it in dotted lines'in Fig. I. Fig. tube, of the actuating member. Fig. VI is a similar view of the slotted disk or keyholeg'uard, which when assembled with the tube shown in Fig. V fills and is confined within the end thereof. Fig. VII is a perspective View of thekeyhole or intermediate tu'be of the actuating member. Fig. VIII is a per- V is a perspective view of the outermost spective View of the innermost constituent 'of the actuating member. Fig. IX is a view similar to Fig. I, showing a modified form of embodimentof my invention. Fig. X is a section on the line X X of Fig. IX, some of the parts being shown in elevation. Fig. Xl is a partial sectional view on the line XI XI of Fig. X. Fig. XII is a side elevation, partly in section, of a further modification of my inventionA on a magnified scale., showing that form of embodimentv thereof which. is specially applicable to light articles intended for pocket use-such, for example, Aas a cigarettecase. Fig. XIII is a side elevation, partly in section, of a modified form of outermost actuating-member tube. Fig. XIV is an end view of the subject-matter of Fig. XIII.

Fig. XV'is a planview of the intermediate actuating-member tube to correspond. to that shown in Fig. XIII. Fig. XVI is a perspective View of the modified disk plate or keyholeguard which constitutes a separable part of the tube shown in Fig. XV, wherein it is also illustrated. Fig. XVII is a View of the innermost tubewhich is assembled with the tubes shown ingFigs. XIII and XV to complete an actuating member.

Referring to the numerals on the drawings, l indicates'by way of illustration a fragment .ofa desk o rfjother article to which certain forms of embodiment of my invention are applicable. v

In Figs. `I to IV, inclusive, of the drawings a lock is shown as comprehending a frameplate y 2 of general though irregularI crossshape. The shape of plate illustrated is nonessential. 1 3 indicatesvscrews representative of means for securing the lframe-plate to the article to v which it is practically applied. The plate 2 is preferably provided with a hollow projection 4, designed to. enter and to snugly fit an aperture, provided for it in the article 1, to which the lock under description is applied. The projection 4 may ofcourse be of a length substantially coextensivewith the thickness of the object l; but I prefer' as a means of rendering the same plate applicable to articles of diierent thicknesses to make it extensible. To that end the projection 4 may be cylindrical, threaded together or the tubes may be united by a tment or telescoped, In either case the plate may be in the first instance provided with an extension 6 of maximum length, which when adjusted to fit the individual article 1, to which said plate is to be applied, is cut oif and may be permanently united to the plate, as by sweating or soldering the members 4 and 6 together.

8 indicates an escutcheon secured, as by screws 9, about the end of the extension or corresponding member 6. The projection 4, whether employed singly or in connection with an extension-piece 6, is designed to accommodate and afford afcase for a multiplex actuating member, preferably a nest of tubes or plurality of tubes fitting' snugly one within the other. The actuating member, as well as the several parts which compose it, may be of any preferred angular or curvilinear contour in cross-section and to its shape should conform the internal contour ofthe case aforementioned which holds it. yThe cylindrical form of contour in cross-section is illustrated in the drawings. A

I illustrate the plurality of members constituting the actuatingmember above referred to as three in number, which they are by preference. Said threev members comprehend, preferably, an outermost tube 10, an intermediate or-keyhole tube 11, and an innermost tube, cylinder, or key-actuated member 12. Provision should be'made for readily assembling the parts of the actuating member within its case by -slipping the actuating member into the case through the opening into the case in the frame-pate 2. It is designed that the actuating member should be readilyr inserted into or-withdrawn from the case through. the

opening in the frame-plate, since in that Wayprovision is made for changing the combination/of the lock; but the parts 'of the actuating member and the actuating member itself should be secured against accidental or intentional disassemblage from without. 'I As a i convenient means of accomplishing that end I provide upon the actuating member case near lts outer` extremity an inwardly-extendlng constrlctlon bounded by a shoulder 15,

and upon the tube 10 a counterpart shoulder 1 6, defining the one end of the reduced port1on 17 of the tube 10, which [its within the constricted portion of thel cartridge-case."

\'I`he, tube 1 0 in turn is providedfor a like purpose with an internally-projecting flange 19, against which the adjacent end` of the tube 11 mlght abut. InI practice, however, I prefer to employ between the end o'f the tube 11 and the iiange 19 an intermediate slotted disk or guard-plate 20, the slot therein being indi- -cated by the reference-numeral21. The tube 11 in turn is closed at its outer end with a head 25, provided with a keyhole or keyholes 'spring 27 terminates.

26 of any preferred shape. The key-actuated member 12, which may be a tube or a solid rod, as preferred, abuts snugly against the head 25 of the tube 11. The assembled actuating member and case above specied are clearly shown in Fig. II, for example, whereinit also appears that the inner ends of the several members of the actuating member when assembled and at rest -in normal position are all flush with thesurface of the plate 2. It might, therefore, be readily inferred, but may be specified, that if the projection 4 be extensible in the manner previously set forth the several parts of the actuating member should be made originally of a length to correspond with that of the maximum length of the member 6 and that all should be cut down to the proper respective lengths after the necessary adjustments are made.

Against the face of the plate 2 I provide a flat spring 27, which, pivoted as indicated at 28 near one end to the plate 2, is provided at the other with a suitable catch-head 29, which through motion to and from the plate may coperate'therewith to constitute a locking member, or, specifically, through the opi eration of the resilient power of the springplate 27 a'spring-cat'ch. The spri'ng 27 extends in normal contact with the face of thel llongitudinal movement within its case of the actuating member or any part thereof.

The spring 27 is held in the position last described against unintentional movementupon its pivot 28, as by a stud-pin 30, projecting from the plate 2, working in a slot 31, elongated endwise of the spring 27, the elongationl of the slot providing for the functional operation of( the'catch-head 29, in which the If force be applied to the catch-head 29 suiiicient to clear the walls of the slot 31 from thepin' 30, the spring 27 may then be turned freely upon its pivot 28, as indicated in dotted lines in Fig. I.

It is obvious from the foregoing description that the mechanism of my device, so far as it has been specified hitherto, is ,adapted through pressure upon the end of the tube 10, projecting as it does in Fig. II, to actuate the catch-head 29. So far as specified, therefore, the mechanism constitutes practically a form of'pusli-fastening device.

It is to accommodate the mechanism specified to thefperformance of the functions of a lock as well as of a push-fastening` that this invention is in part devised. -To accomplish that end, I provide meansfor restraining all but the innermost member of the actuating member from endwise lnovement, employing forthe purpose the latch, detent, or dog 33,

pivoted, as indicated at 34, to the face of the plate 2 and swinging between stop- pins 35 and 36 thereon, as illustrated in full and dotted lines in Fig. I. The dog 33 is provided at one end with a knob or handle 37 and at the other with two curved faces 38 and 39. The

face 38 is shaped and located, so that only the ber.

invention, and has a'pair tube 12 may fairly clear it when the dog is set in the dogging position', as' shown infull lines in Fig. I. On the other hand, the face 39 is shaped so that when the dog is setin the position illustrated 'in dotted linesl in Fig. I it clears the entire actuating member and permits it to operate precisely as if no dog were present-in other words, as a push-fastening.

The spring 27 adjacent to the catch-head29 is made of thickened material, as indicated at 40 in Fig. II of the drawings, in order to accommodate the undercut41 for the sweep of the nose of the dog, as indicated in Fig. I of the drawings. The dog being made of resilient metal and with an inwardly-projecting button 42, formed upon the inner end of the shank of the knob 37, as shown in Fig. III,

is adapted through engagement with shallow recesses or depressions 43 in the face of the plate 2 to remain fixed .against acclental dislodgment in either of the two positions to which 1n Fig. I. In that figure one of the recesses 43 is illustrated, the other corresponding recess being covered by the dog.

It was above specified that when the dog-is in the position shown in full lines in Fig. I it serves to prevent endwise movement of all but the innermost part of the actuating mem- 'Ihat member is designed to be actuated exclusively by a key 45. (See Fig. III.) The key illustrated is of thesimplest form, designed solely to illusirate the principle of my of legs 46 to fit the keyhole 26, which the legs readily reach by a slight twist of the key, 'if necessary.. after they are inserted into thefslot 21 of the guarddisk 20.- Passing through the keyhole 26 the legs 46 impinge against the innermost part 12 of the actuating member, which by endwise pressure upon the key readily drives the catch-head 29 against the resistance of its spring 27. f

The guard-disk 20, vwith its slot 21, the plurality of apertures constituting a single keyhole 26, and the bifurcated key are offered as mere suggestions of a practically infinite variety of means by` hich the picking of the lock may be guarded against.

- m Any of the usual means employed lfor se- -curing one movable member to another in locks or any suitable means which may be devised for the purpose are contemplated as applicable to my invention in the broad Iscope here illustrated, wherein` are shown only the movable members and one form of locking mechanismof the simplest kind.

` Through the swinging of the dog 33 to the p0- i out having to draw any screws. In

tally,

it is designed to -be shifted, as shown.

substantially identical with sition shown in dotted lines and of the spring similarly shown in Fig. I of the drawings it is practicable to withdraw the actuating member from its lcase and to substitute another therefor without the use of any tools and withthis way provision is made for the ready change of the combination of the locking mechanism. One mode of changing such combination may be in changing the shape or configuration of the keyhole, illustrated as carried Within, the intermediate part 11 of the actuating member, such change, of course, involving a change of the guard-plate 20. Accordingly., in the modification illustrated in Figs. IX to XI, inclusive, of the drawings, supplemented by the detail views, XIII to XVII, I show a device for changing the keyhole without change of the entire tube which carries it. I also illustratevin said modification modified means for assembling and dogging the parts of the actuating member, including, incidenmeans for preyenting rotative movement of said parts.

Referring to the figures last designated, 50 indicates a portion of an article to which the lock is secured; 51, the frame-plate secured thereto, as by screws 52; v53, a spring-plate carrying a' catch-head 54, with which a portion of a striking plate or hasp 55 is shown engaged. 56 indicates a stud projecting from the plate 51 through an oblong aperture 57 in thespring 53. rlhe actuating member is made up of an outermost part 58, an intermediate part 59, and an .innermost part 60, like the actuating member already specified; but the outermost and intermediate parts thereof are provided with eccentric fianges 61 and 62, respectively, each of which is provided withan outwardly-opening notch 63 and 64, respectively, adapted and designedto engage the stud 56 in the assembled device. A dog 65,4 pivoted to the frame-plate 51, as indicated at 66, is adapted to retain or release lall but the innermost part of the actuating member at the will ofthe operator. The dog 65 being the dog 33, pre-l viously specified, there appears to be no occasion to respecify'structural details already described, except to specify them by reference to the dog 33. The dog 65, however, instead of covering and uncovering the'ends of the parts of the actuating member, as the dog does, works in slits 67 and 68, provided for it in the members 58 and 59, respectively, rendered accessible tuating'- member case 71, that is preferably made integral with'the plate 51.

The end of the member 58 is provided with an internally-constrictive flange 72, designed to retain a slotted guard platel 73, against which abuts a keyhole-disk 7 5, Athat is operatively secured to the intermediate part of the actuating member 59. The keyhole-disk 75, although operatively secured to the member through a slit 70 in the acl 59, is not in the modified form of embodiment .of the invention under description made integral therewith, but is provided with a mutilated collar 76, which makes joint with the stepped end 77 of the member 59. (Compare Figs. XV and XVI.)

To one skilled in the art it will be obvious from the foregoing description that when the parts are 'assembled the members 58 and 59 are irrevolubly fixed by the engagement of their notches 63 and 64 with the stud 56.` When engaged by the dog 65, as shown, for instance, in Fig. XI, they are immovable lengthwise; but the innermost member may be actuated by a proper key and by its end thrust displace the spring 53, thereby releasing the catch-head 54 and thehasp 55. .When released from the dog, the same operation may be effected by pressure applied against the projecting end of the member 58, which when so released operates as a push-fastening.

In the form of embodiment of my invention last specified the shape of the keyhole may be varied at will by simply vchanging the guard-plate 73 and the keyhole-disk 75.

In Fig. XII of the drawings I illustrate a form of embodiment of my invention especially adapted for light articles, such as cigarette-cases. `Referring thereto, 78 indicates the case, 79 the outermost part of the actuating member, and 8O the intermediate part thereof. The innermost member is omitted; but its place is supplied by the key 81, provided with a tang 82, which operatively impinges against the spring fastening-plate 83. 84 indicates a slotted guard-plate secured within the member 79 by an inwardly-projecting flange 8 5 thereof. The member. 79 is in turn secured within its case 78 by an inwardly-pro-l jecting flange `-86, engaging withits shoulder 87. 89 indicates a sliding dog provided with a handle 90 and adapted to engage or disengage the members -79 and 80 at will by means of registering apertures in the parts 78, 79, and 80, respectively; as illustrated. When the dog 89 is in the dogging position illustrated in Fig. XII, the device becomes a keyactuatablelock; but when the dog is slipped back to the end of its guideway 91 it becomes a push-fastening. 4 4

The modeof operation of my invention in the various forms of embodiment thereof herein illustrated and described isdeemed to have been sufficiently set forth in the foregoing specification, except that it may be added, perhaps to advantage, that the dog in each instance is located in a position to be non-accessible from the outside of the article secured by the lock when said article is closed or in the locked position and' that by that means the obviously necessary provision may be made for putting the setting of the locking mechanism exclusively within the control of the holder of a key thereto.

In a lock, the combination with a frameplate, locking member, actuating member and case, any part of which actuating member may singly actuate said locking'member, of means for restraining the movement of a portion but IOO not alll of the actuating member, whereby a variety of means for actuating the locking member may 'beemployed 7. In a lock, the combination with a frameplate, actuating/member and case, of a springactuated locking member removably confining the actuating member Within the case.

8. In a lock, the combination with a frameplate, locking member, multiplex actuating member and. case, the actuating member or any part thereof constituting `means for actuating the locking member, of means permitting operative substitution of one'actating1 member for another within the case at wil J 9.
