LOCK AND FASTENING.

Specification of Letters Patent.

Patented Apr. 11, 1911.

Original application led .Tune 25, 1904, Serial No. 214,118. Divided and this application filed October 23,

Serial No. 459,232.

To all whom it may concern:

Be it known that I, JOHN SMALLEY CAMP- BELL, of Plainfield, New Jersey, have invented certain new and useful Improvements in Looks and Fastenings, of which the following is a specification.

My present invention relates to a lock or fastening in which provision is made for its conversion, at will, into a spring-push-fastening or a keylock, and is designed and adapted especially, but not exclusively, for use upon light articles of personal wear, such as handbags, cigar and cigarette cases, and the like,

It has for its object the production of a device of the class described, which may be embodied in small and compact form without sacrifice of any of the features belonging to fastenings of its class.

The class to which the present invention belongs is that described inV United States Letters Patent No. 7 57 ,265, issued to me April 12, 1904, the present application being one divided out of my application, Ser. No. 214,118, liled June 25, 1904.

I-Iaving now pointed out, in general terms, the object of my present invention, it is deemed sufhcient to add that that which specifically constitutes my present invention will be hereinafter specified in detail and succinctly set forth in the appended claims.

In the accompanying drawings, which constitute a part of this specification, I illustrate my invention, in its present preferred form of embodiment, drawn to a highly magnified scale in order to clearly show the details which would be somewhat too minute Vto be clearly legible if the drawings were made to actual scale.

In the drawings aforesaid, Figure I is an inverted elevation of my lock complete, certain of the parts being broken away. Fig. II is a view similar to Fig. I showing the subject matter thereof in top plan. Fig. III is a fragmental elevation of a portion of the subject matter shown in Fig. I, showing the outside of the lock in the position shown .in that ligure partially broken away. Fig. IV illustrates, in section, the operation of the lock by a key inserted into it and partially broken away. In this figure, is illustrated, in juxtaposition to the lock-plate, the member of a receptacle with which, in practice, the latch of the fastening mechanism engages, the latch and the part which it engages being shown disengaged under the actuation of the key. Fig. V is a fragmental elevation of the subject matter of Fig. I, showing the key-set-plate turned to liberate the spring-actuating mechanism from the look-plate, and to convert the device into a spring-push-fastening. Fig. VI is a view similar to Fig. IV illustrating the operation of the device as a spring-push-fastening, the shell of the actuating-member being shown in elevation, partially broken away. Fi VII is a section on the line VII-VII of Fig. VI. Fig. VIII is a view of a portion of the subject matter of Fig. IV, partially in elevation, the key-set-plate being in the position shown in Fig. I, and illustrating a modified form of key and key guard, the key being shown in the initial position of inserti-on in which it may clear the ward. Fig. IX is a section on the line IX-IX of Fig. VIII. Fig. X is a view similar to Fig. VIII, showing in full lines the key turned at right angles to the position illust-rated in Fig. VIII, and, in dotted' lines, the inthrust movement of the key through which it may gain operative access to the lock spring. Fig. XI is a section on the line XI-XI of Fig. X. Fig. XII is a side elevation of the key shown in Figs. VIII to XI, inclusive, detached.

Referring to the numerals on the drawings, 1 indicates a lock-plate or. assemblingmember by which, in conjunction with the face-plate 3, my device may be operatively secured to a receptacle upon which it is adapted to be employed. The face-plate 3 is designed to be incorporated with one member defining the mouth of the receptacle, the other member thereof beingindicated by the numeral d in Fig. IV of the drawings. The members which carry the parts 3 and t may be movably united in any ordinary or preferred manner, as by hinges, not illustrated.

Against the inner face of the lock-plate 1 is secured an elongated'flat spring 5V whose resiliency causes it normally to lie contiguous to the lock-plate, and which preferably extends from end to end thereof. The.

spring 5 is preferably secured at its opposite ends to the plate 1 by any suitable means,

preferably such as may permit the removal of the plate for permittingaccess to the lock mechanism. To that end, I 'provide a returned bend 7 upon one end of the -lockplate provided with apocket 8 for the reception of one end of the spring 5. At the opposite end of the plate 1, I prefer to provide a pair of lugs 9, separated a sufficient distance to accommodate the adjacent end of the spring 5 between them, and in apertures in the lugs 9 I provide a pin 10, which confines the spring 5 in place between the lugs and is securely but removably held iny place by frictional engagement between the spring, the pin, and the lugs, respectively.

The spring is preferably provided with one or more projections 12, which, extending at right angles to the longitudinal axis of the spring, terminate each in a latch 13 adapted to engage and disengage the member il, a recess 14 (see Figs. IV and VI) being provided in the face-plate 15 of the member 4 for their admission.

The lock-plate 1, being, as specified, the assembling-member of my mechanism, I provide upon it suitable means for mounting the spring-actuating-member of the multiplex type described in my previous patent, by aid whereof my device is convertible, at will, into a key-lock or a push-fastening. To that end, I provide upon the lock-plate 1 a preferably integral and annular barrel 16 that projects outwardly from the lockplate in the direction of and underneath the face-plate 3 (compare, for example, Figs. II, III, and IV). This barrel confines and accommodates to its reciprocatory motion the outer tubular shell 19 of the multiplex actuating-member, which fits the bore of the barrel and is, like it, preferably of cylindrical shape. The shell 19, though longitudin-ally movable within the barrel 16, is irrevoluble therein, its limitations in that respect being fixed by the engagement of a lug` 20 projecting from the periphery of the shell into a longitudinal slot 21 formed in the inner wall of the barrel and extending from end to end thereof, as clearly shown in Figs. II, III, and IV.

The outward movement of the shell 19 within the barrel 16 is limited by a key-setplate 23 that collars the shell near its inner end, being revolubly accommodated thereon by an external annular recess 24 formed in the shell and secured by a cap-plate 25, whose edges overhang the recess 24.-, flangewise.

The cap-plate 25 is preferably secured, as by brazing, to the end of an internal sleeve 26 that fits snugly within the bore of the shell 19 to which it is separably united, as by a pin 27 that penetrates the shell and the sleeve, as clearly shown in Fig. VII.

The shell 19, constructed and assembled as specified., is confined within the barrel by the spring 5, and, without further provision than that already specified, constitutes a complete and eflicient actuating-member for the spring in a manner to operate it and its latches 13 like any ordinary push-fastening. In order to operate the shell 19 as a pushfastening, pressure, as by the thumb, applied against the outer end of the shell is sufficient to drive the shell, with the specified members attached thereto, against the spring, as

clearly shown in Fig. VI, thereby disengaging the latches 13 from the member 4L..

To the extent hitherto specified, the keyset-plate 23 performs no other function beyond that of limiting the outward movement of the shell 1,9, but it is provided for the'definite function of converting the actuating-member, o-f which the shell 19 is a part, into a key-lock, and is mounted upon the shell in the manner described in order to contribute to my convertible fastening that compact form of embodiment that is essential to the availability, in practice, of my present invention. Accordingly, I provide upon one side of the key-set-plate 23 an extension 29 having upon it a knob 30 by which it may be manipulated and partially rotated within the recess 211 in which it is mounted. The extension 29 preferably carries a lip 31 adapted to engage and disengage a keeper' 32 (compare Figs. I and II) that is secured as by rivets 33 to the face of the lock-plate 1, and isformed with a recess 34E adjacent to the face of said lockplate for the reception of the lip 31. It will now appear that if the extension 29 be turned so as to cause the lip 31, to enter the recess 34, `the engagement between the lip 'and the keeper will serve to confine the shell' 19 within the barrel 16, and to interrupt the operation, previously described, o-f the shell as a push-fastening. It is only when the key-set-plate is shifted to the position shown in Fig. V to disengage the lip 31 from the keeper 32 that the device is adapted to be operated as a push-fastening in the manner specified.

During such time as the lip 31 engages the keeper 32, operative access to the spring 5 can be gained only through the instrumentality of a certain key. `Repeating at this juncture reference to my previously recited patent as indicating the extent to which the mechanism contained within the shell 19 may be modified within the contemplated scope of my present invention, I proceed to specify that I prefer to provide for the actuprotection of shell against intrusion communicated to the spring to operate it. To the end last specified, I prefer to provide the cap-plate 25 vv'ith an eccentrically disposed Vaperture 35 through which may pass, into operative engagement with the spring, the tang 36 of a key 37. If the key 37, provided with a suitable tang 36, be inserted into the outer end of the shell 19 and turned so as to register the tang with the aperture 35, it may gain access to the face of the spring 5 and drive it with its latches 13 away from the face of the lock-plate 1, as clearly illustrated in Fig. IV, thereby disengaging the latches from the member 4.

I prefer to provide means for'guarding the 'shell against the intrusion of an improper key, such, for example, as a suitably slotted disk 39 rotatably secured within the outer end of the shell as between the end of the sleeve 26 and an internal annular fiange 40, formed in the outer end of the shell 19. A slotted septum 41, formed integral with the shell 2G, may be also provided for the of any butthe proper key.

In Figs. X to XII, inclusive, I illustrate a slightly modified form of my device into which is introduced a ward to compel rotative movement of a proper key as a condition precedent to its gaining operative access to the spring 5. Referring to the numerals displayed upon those gures, indicates a lock-plate corresponding to the lock-plate 1, and provided witha barrel 46, corresponding to the vbarrel 16. 47 indicates'a shell corresponding to the shell 19. The parts under consideration are identified by different numerals for no other reason than that they are differentiated from the parts previously specified by providing within the barrel a slot 48 of limited extent as contradistinguished from the through-and-through slot 21 previously specified. This formal modification of detail is adaptable to either' of two forms of embodiment of my invention shown in the drawings. The slot 43 is designed to accommodate a pin 49 corresponding in function to the pin 20 previously specified. Within the shell 47, I provide a sleeve 50 having a closed end 51 and an annul-ar flange 52 that confines against the end of the shell 47 a key-vset-plate 53, identical in function, and likewise in form, if preferred, with the key-set-plate 23 already specified. The closed end 51, which corresponds to the cap-plate 25, is provided like it with an aperture 55 corresponding to the aperture 35. The sleeve 50 confines within the internally flanged end of the shell 47 a slotted disk 56, through which a suitable key 57 may be inserted. It may be observed y that to this point, with the Vslight modifications of detail specified, the subject matter of Figs. VIII to XI is substantially identical to all int-ents and purposes With the construction of the shell 19 and its parts appurtenant. The distinctive feature of the form of embodiment of my invention now under consideration is found in the presence within the shell 47 of a. ward 59. This ward consists of a pin fixed in the shell 47 and projecting preferably in a radial direction `therefrom and through the sleeve 50. The

ward 59 is located to cover the aperture 55 so that a key inserted through the slot in the disk 56 may not pass it 'except the slot of the disk 56 be disposed at right angles to the aperture 55 and the key be of proper dimensions. After passing the ward 59, the key must be tted to the accomplishment of its function, for the reason that being necessarily inserted at right angles to the aperi ture 55, as shown in Figs. VIII and IX, it must be partially rotated before its tang 58 may register with the aperture 55. Next, it must be susceptible of an inthrust sufficient to properly actuate the spring 5. The ward 59, although susceptible of variation, is illustrated in its simplest form of embodiment, and the key 57, in like form of embodiment, is illustrated in Fig. XII, it being there shown, as well as in Fig. X, with a gating 60, shaped to permit the requisite rotative and inthrust movement of the key, as will appear from comparison of the successive Figs. VIII to XI, inclusive.

In view of the reference in the foregoing specification to the method' of operation referred to again and again, it is sufficient to briefly add by way of description of the operation of my device that if the knob 30 be set in the position shown in Fig. I, for example, the device may be operated only as a key lock. The key 37, if the lock be of the form shown in the figures preceding Fig. VIII of the drawings, may be employed to actuate the spring 5. If, on the other hand, the lock be provided with the ward 59, as shown in the subsequent figures of the drawings, a key 57 must be employed. If the key 57 be the proper key, the presence of the ward 59 compels the necessity of both rotative and inthrust movement of the key in order to enable it to actuate the spring 5.

If the knob 30 be set in the position shown in Fig. V of the drawings, the necessity for the use of a key is eliminated, and the device may be operated simply by pressure upon the end of the shell 19 or 47, whichever be provided, after the manner illustrated in Fig. VI.
