The present invention relates to a structure into which indicia such as initials. or thelike may be placed fordisplay-purposes, said indicia being retained therein in apositive manner but being readily removable therefrom for replacement, and to a watchintowhich such a structure may be incorporated;

The use of initials or other interchangeable decorative or identifyingindicia in various ar-, ticles, and particularly in articles of personnal' adornment, is quite widespread; It has heretofore been thought that" if such indicia are to appear integral with the object to which they are secured, they must be more or; less perma nently'attachedthereto. Consequently, the task of attaohingsuchindicia is generally arelatively complicated one, involying the use of tools and equipment not readily available to the general public and the exercise of'skills which the gene eral public does not have, Hence the placing of initials or other indieia upon precious or semiprecious articles of ac l ornrnent, such as braceets brooches, pinswatch or t e i e h r qu r d e se ices and" time oi a jeweler. t cl' bv ously beimpossib e r t e v o such, a ticles to has on handa siiflicien ly large inv nt ry wi h init a a re atta hed to commode-ta ll" pmspective ase s t er f. He must. th refor in o der t sel a Si net atch or bracel'etattach e a r ate ls thereto himself: This involves considerable time andtrouble, and'usua lly, requires the services of a skilled artisan. such as a watchmaker, thus preventing suchan artisan from utilizing his time more profitably;

Upon damage to or deterioration of" the initials or other indicia which have been secured totheornamental object; it-has in the past been necessary for the owner thereof to return to the place from which he purchased the object, that establishment-generally performing thereplacement of the indicia gratuitously in order to retain good will; This represents another source of loss on the part of the vendor, yet it;

general public. Moreover, securingdeviees of the prior art which have beenuseable with 2 watches have necessarily been so fragile that only a limited-number of removals and replacements could be carried out before failure or breakage of the housing structure.

The present invention'has for its primary object the provision of a; retainer for removable indicia in which the retaining mechanism is of a type such that it can bemanipulated by persons without any particular skill and-without requiringthe use of specialized-- tools, to the end that removal and replacement of initials or other indicia may be made at will and whenever necessary either 'by'the owner thereof or, in the case or the initial sale, by the salesman and not" by a skilled" artisan; Another object is to provide such a retainer which is particularly adapted for use with small objects such as watches, the retainer and the watchbeing so cooperatingly constructed that the retainer is securable to portions of the watch case in such a manner as to blendunobtrusively therewith, thus achieving an impression of integralness which adds to the esthetic appeal of the watch.

This is achieved by forming the retainer in two parts; a housing into which indicia may be inserted and'through a, portion of which they may be viewedand closure articulately mounted'within the housing so as to be positively held n a r taining 2051 9101 u being readily cessible from the outside of the housing and being readily movableto areleasing position, pert i t e' ndicia t9 e eaw d r rte The c osure: heldiiare ain n position by interengage nent between a projection on the closure and an aperture the housing, When the proje i n s o ed inwa d b eans of Pr e p ed" f m e outside of the u it becomes disengaged from the aperture and the closure is thereby permitted to move to releasing position. In order to prevent the projection fromsnapping back into the aperture when it is released and before the'closure has been movedawayfrom its retaining position, cam surfaces are provided on the closure which, when the projection is: moved-inwardly and disengaged from the aperture; forcethe projection to move downwardlyout of registration with its cooperating aperture and: independently of the release of the closure. Consequently if-the-projection, after having beenmoved' to that position, isreleased; it wil-lnot snap back into its cooperating aperture, and the" closure can then be moved" in a convenient manner toits releasing position. In order to permit a single operation to release the-projection from itsaperture and at the same time move the closure to releasing position, a second aperture is provided which has an open bottom, the insertion of a tool through that second aperture causing the projection to move inwardly and then downwardly, as above described, the tool then being movable down wardly through the open bottom of the aperture so as to carry the closure with it to releasing position.

To the accomplishment of the foregoing objects, and such other objects as may hereinafter appear, the present invention relates to the construction of a retainer for removable indicia, and to a watch in which such a retainer is incorporated, as defined in the appended claims and as described in this specification, taken together with the accompanying drawings in which:

The retainer of the instant invention is here disclosed as embodied in a signet watch, for which it has been particularly designed insofar as details are concerned, but the broader aspects of the invention are not limited to that particular embodiment.

The watch comprises a case 2 having spaced lugs d at either end thereof, these lugs being provided, as is conventional, with horizontal apertures 6 through which a retaining pin or the like may be passed in order that the ends of bracelet 8 may be secured thereto. The tops of the lugs are provided with appropriate recesses 9 into which the retainer of the present invention is received as by a press fit, the retainer bridging the lugs 4 at the top of the watch above the bracelet 8 and blending with the configuration of the lugs i so as to give an appearance of integralness and substantiality.

The retainer, broadly considered, com arises a housing generally designated A into which indicia B in the form of initials or the like may be placed, the housing having a closure pivotally mounted therein and movable between a retaining position within the housing A and spaced from the top thereof, the indicia- B being retained in the housing A between the walls thereof and the closure C (see the solid lines in Fig. 7) and a releasing position extending out of the housing A and exposing the open bottom thereof, so that the indicia B can be removed or replaced (see the broken lines in Fig. '7).

The housing A is defined by front side wall iii, rear side wall l2, end walls i4 and a top lip or flange i inwardly directed from the walls I9, l2 and i4 and defining a restricted opening :8 at the top of the housing A. No bottom wall is provided, the housing A thus having an open bottom. The rear side wall 12 is deeper than the front side wall I 0 in the present embodiment, thus permitting the housing A to be received within the recesses 9 in the lugs 4, to conform to the configuration of the lugs 4 and to extend out therefrom in an attractive and decorative manner so that the front side wall [0 and a substantial portion of the open bottom of the housing A are exposed (see particularly Figs. 4, 5 and '7) The indicia B, here shown in the form of individual letters of the alphabet, comprise a body portion 20 in the form of a desired letter and having a height such as to be received within the opening l8 at the top of the housing A, flanges 22 of less height than the body portion A and extending therefrom fitting inside the walls l0, l2 and M of the housing A so as to be passable through the open bottom thereof but not passable through the opening l8 at the top thereof. The flanges 22 thus position the body portion 20 of the indicia B within the opening it) at the top of the housing A, but prevent the indicia B from moving out through the open top of the housing A. Since, as will be apparent from Fig. 8, the flanges 22 have a substantial length, and since they preferably fit relatively snugly between the front and rear side walls [0 and 12, they also control and fix the alignment of the body portion 20 within the housing A, causing the letter to have its vertical axis perpendicular to the longitudinal axis of the housing A. In the present embodiment three separate letters of the alphabet are employed, but it will be apparent that an integral unit comprising all three letters could also be employed, and that different numbers of letters could also be used.

The closure C, the function of which is to releasably retain the indicia B in the housing A, is preferably formed of an integral piece of resilient metal defining a pair of spaced parallel arms 24 and 26, connected at one end by a portion 28. The arms 24 and 26 extend parallel to and close to the front and rear side walls I0 and :2 respectively along substantially the entire length of the housing A, the flanges 22 of the indicia B resting on the arms 24. and 26. The length of the closure C is less than the distance between the watch lugs 4. Ears 30 are formed on the portion 28 and are received within oppositely disposed apertures 32 in the front and rear side walls it and i2 respectively near one end of the housing A and positioned below the undersurface of the lips [6 by a distance closely equalling the thickness of the flanges 22 on the indicia B, and also positioned inside the watch lugs t. ihe closure C is thus pivotally mounted within the housing A so as to be movable between the retaining position illustrated in the solid lines of Fig. '7, in which position it effectively closes the open bottom of the housing A, and a releasing position pivoted downwardly between the watch lugs 4 in a clockwise direction from its retaining position, as indicated in the broken lines in Fig. 7, in which position the open bottom of the housing A is effectively exposed.

In order to hold the closure C in its retaining position the arm 24 is provided, at its free end opposite from the connecting portion 28, with an outward projection 36 which, when the arms 24 and 26 are in their normal parallel position, is received within an aperture 38 in the front side Wall ID inside the Watch lugs 4.

It will be understood that so long as the projection 36 is received within the aperture 38, the resiliency of the arm 24 tending to keep it wardly at the same time that the projection 3B is pressed inwardly, for otherwise release of inward pressure on the projection 36 will merely permit that projection to snap back into the aperture 38. This requires two-hand operation, and moreover the closure C is so positioned as not to be readily accessible. Downward pressure on the indicia B mightbe employed, but this is not always possible, it being borne in mind that the top of the housing A need not be open, as at It, but may have a corresponding transparent area through which the indicia B may be viewed.

In order to avoid this drawback, each of the arms 24 and 26, at their free ends, are provided with oppositely and inwardly directed fingers 40, 42, the finger 40 terminating in an outwardly and upwardly inclined cam surface 44 engageable with the outwardly and downwardly inclined cam surface 46 in which the arm 42 terminates (see Fig. '7). The surfaces 44 and 46 are preferably adapted to engage one an other after the arm 24 has been moved inwardly a sufficient distance for the projection 36 to become disengaged from the aperture 38. The application of further inward pressure on the projection 36 will cause it to move downwardly with respect to the arm 26, upward motion of the arm 25 being prevented by the flanges '22 of the indicia 13. Consequently, the projection 38 is moved downwardly out of registration with the aperture 38, and hence when pressure is released therefrom it will not .snap back into the aperture 3.8, but will instead engage the inner surface of the front side wall ll). Thereafter the closure C may be grasped from the underside of the housing A, or in any other manner, and pivoted to releasing position.

In order to permit a single manipulation to move the closure C from its retaining to its releasing position, an additional aperture 48 is formed in the front side wall l inside the watch lugs 4, this aperture passing completely therethrough and extending vertically all the way to the lower edge of the wall 10, being open at that edge. The upper portion of the aperture 48 is in line with the edge of the arm 24 when the closure 0 is in retaining position. When, as illustrated in Figs. 5 and 6, a pointed tool 40 is inserted through the aperture 48 so as to engage the arm 24, inward pressure exerted by the tool 40 will move the arm 24 inwardly (compare Figs. 3 and 6) until the projection 36 has become disengaged from the aperture 38. Further inward pressure will, through intermeasement of the cam surfaces 44 and 46, cause the arm 24 to move downwardly, and as a result the pointed tip of the tool 40 can slip over the top of the arm 24. Downward movement of the tool 46 out through the open bottom of the aperture 48 will thus carry the arm 24 therewith and hence will positively cause the closure C to move to releasing position, exposing the 6 open bottom of the housing A and permitting the indicia B to be removed or replaced.

Thus a single operation comprising the movement inwardly and then downwardly of the tool 40 will effectively release the indicia B. The operation requires no special tools or special skill, and may be performed by anyone at any time. All of the parts of the structure are simple and susceptible of inexpensive mass production in drawing or stamping operations. The interaction of the cam surfaces 44 and 46 cooperate with the manner of mounting of the closure C within the housing A and with the shape and orientation of the aperture 48 through which the tool 40 may be inserted, in order to facilitate ready manipulation of the closure C.

While but a single embodiment of the present invention has been here disclosed, it will be apparent that many changes may be made in the detailed structure thereof without departing from the spirit of the invention as defined in the following claims.
