referring now to the drawing , indicated generally at a is a finger ring of the type having a circular band or shank 10 at the top of which is located a setting 11 illustrative of various types of settings found upon rings , such setting having portions 13 , 14 which extend upward from the sides of shank 10 . secured to ring a is a device b of the invention which is utilized for securement of the ring upon a finger of the wearer of the ring . as a matter of generality , device b comprises a size - reducing element 16 configured for fitting within the circular opening 17 of the ring for interposition between an inner peripheral surface 18 of opening 17 and a corresponding palmar surface of the finger which , in fig2 is designated representatively at 20 . device b includes hinge means 21 for securement to the outer peripheral surface 23 of the shank 10 opposite from the inner peripheral surface 18 without necessitating modification of shank 10 . the device comprises an arm 24 interengaging element 16 and hinge means 21 to provide movement of the size - reducing element 16 between an open position , as depicted in fig6 and a closed position as depicted in fig1 and 2 . in the open position the size - reducing element 16 is displaced from opening 17 for permitting unemcumbered insertion of the finger 20 within the opening and , as will be apparent from fig6 the opening 17 of the ring is entirely free and unobstructed by any portion of device b . however , in the closed position size - reducing element 16 is fitted within opening 17 to effectively reduce the size of opening 17 and , as appreciated from fig2 is interpositioned between the inner peripheral surface 18 of ring shank 10 and the palmar surface of the inserted finger 20 . the new device b is also provided with a feature , as described more fully below , for resiliently retaining size - reducing element 16 in the closed position shown in fig1 and fig2 . setting 11 of ring a is seen to be of relatively heavy , elaborate character and as including the supports or structural members of the setting 13 , 14 extending upward from the sides of shank 10 so as to illustrate the suitability of device b for use with a relatively complex and unusual ring with which the various prior art arrangements for altering the size of the ring shank or hinging of the same could not effectively be utilized . in this regard , it is to be noted that ring shank 10 is also of a tapered configuration , as appreciated best from reference to fig4 wherein the shank 10 is thicker at a bottom portion 25 than at an upper portion 26 , a type of construction rendering most difficult the adaptation or use of a ring - securement device of the prior art . this is not to suggest , however , that the present device is utilizable only with rings of relatively complex and unsual character . on the contrary , the numerous advantages of the new ring securement device b may be realized in conjunction with attachment of the same to a relatively simple ring , as well as those of complex or unusual configuration . therefore , it is to be understood that the present description is not meant to limit in any way the use of the invention , nor to imply that use of ring securement device b is to be employed with only one or more of certain distinct types or configurations of rings . ring a is , accordingly , depicted merely for purposes of illustration . the specific features of ring securement device b are now described in greater detail . size - reducing element 16 is of crescent shape , having a central portion 28 carried at the distal end of arm 24 and thence tapering laterally to the opposite sides of arm 24 and central portion 28 to reduced thickness opposite end portions 29 , each of which is preferably provided with a blunted or rounded end 30 . inasmuch as ring shank 10 may be of gold , silver , platinum or various alloys , size - reducing element 16 , arm 24 and other members of ring securement device b may be of the same or similar metals or alloys in order to provide the identical appearance or luster of the ring . also , it will be immediately recognized that ring a is merely representative of one of many different possible sizes in which rings are conventionally available . however , it is not requisite that size - reducing element 16 provide a closely conformal fit within the inner peripheral surface 18 of the ring shank . the drawings illustrate , in fact , some difference in size . as a consequence , a size - reducing element of given dimensions can fit a number of different ring sizes . this is a substantial advantage for the manufacturing jeweler who may keep in stock a limited number of ring securement devices b having size - reducing elements 16 of only a few different sizes , but which will be utilizable for attachment to rings of many different sizes . attachment of the device is best understood by explication of the features of hinge means 21 , which is seen to include a pair of tubular members 31 , each being brazed or soldered by conventional jeweler &# 39 ; s techniques , to the shank 10 of the ring as indicated at 32 , 33 , so that the tubular hinge elements or members 31 are spaced apart on the outer peripheral surface 23 of ring shank 10 by a distance slightly greater than the width of arm 24 . carried at the proximal end of arm 24 is a tubular hinge element extending transversely with respect to the arm and is secured to the arm in offset relationship with respect thereto so that it is located between tubular elements 31 . a hinge pin 37 is receivable by each of the hinge elements 30 and 35 in a tightly fitted relationship and extends through each of the latter elements to provide a secure and mechanically simple hinging relationship between arm 24 and the ring . the interconnection of size - reducing element 16 and arm 24 is preferably constituted by an integral relationship as by casting of the element 16 and arm 24 as a single piece . arm 24 is of substantially thin , flat character throughout its extent between hinge element 35 and the central portion 28 of size - reducing element 16 with which it is interconnected . however , at the distal end , arm 24 tapers outwardly away from central portion 28 of element 16 to provide a wedge - shaped extension 38 having an outer shoulder 39 which is substantially coplanar with the surface 40 of the central portion 28 of element 16 , which surface is to engage the finger 20 of the wearer as depicted in fig2 . preferably , for purposes of comfort , the shoulder 40 of extension 38 is somewhat rounded , as best seen in fig5 . extension 38 serves a most useful purpose in that it is provided with a small aperture 42 in that face 43 of extension 38 which extends at a slight angle with rspect to the longitudinal axis of arm 24 , such aperture being suited for receiving the tip 45 of an elongated tool 46 of pin - like character . thus , the aperture is oriented for positioning of the tool transversely with respect to hinge means 21 with the tool being oriented as depicted in fig4 . the tool is utilizable by prying movement as depicted in the direction of arrows in fig5 for disengaging size - reducing element 16 from its closed position . as alluded to above , element 16 is resiliently retained in its closed position , i . e ., that depicted in fig1 and 4 , by structural features of the device . for this purpose , a pair of rounded projections 48 are provided proximate respective opposite ends 30 of size - reducing element 16 . ring a is provided with a pair of indentations 50 in the innter peripheral surface 18 of ring shank 10 which respectively correspond to projections 48 . it will be apparent that indentations 50 are adapted for receiving projections 48 to retain size - reducing element 16 in the closed position . the interengagement of these projections 48 with indentations 50 is shown by dashed lines in fig1 and 2 . by virtue of the resilient nature of arm 24 and element 16 , the latter member is quite securely retained in closed position by the reception of projections 48 within indentations 50 . although the size - reducing element may be displaced by deliberate manual pressure applied to the surface of element 16 opposed from extension 40 , the use of a tool 46 as depicted for prying open the device completely simplifies opening the size - reducing element even for those with limited movement of their hands , as is sometimes characteristically associated with arthritic affliction . in this position of the ring a upon a finger of the wearer , it is manifest that size - reducing element 16 is first placed in the open position , as depicted in fig6 . ring a may then be placed on the finger of the wearer , with the size - reducing element 16 extending outwardly from the ring , as illustrated in fig7 so that arm 24 is above element 16 when the latter lies on the palmar surface of the ring finger 20 . accordingly , upon placing manual pressure against the arm extension 38 , size - reducing element 16 is relocated to the closed position shown in fig2 providing interengagement between the inner peripheral surface 18 of the ring and palmar surface of the finger 20 of the wearer . when the ring is placed upon the finger and device b is configured as illustrated in fig7 closure of size reducing element 16 is such that arm 24 bears against ring shank 10 as indicated at region 52 in fig5 by virtue of the offset relationship of arm 24 with respect to the hinge axis defined by hinge pin 37 and also with respect to size - reducing element 16 . therefore , any attempt to pull the ring from the finger of the wearer , as through accidental application of force , serves only to cause arm 24 to bear even more tightly against the outer shank surface 52 . in this way the size - reducing element is prevented by the arm from being displaced from the closed position upon attempted withdrawal of the ring from the finger . however , upon insertion of a pointed object , such as tool 46 within aperture 42 , simple prying movement of the tool will easily and quickly open the device for permitting withdrawal of the finger from the ring or readjustment , etc ., although , manifestly , the same could be accomplished by manual pressure against the face of size - reducing element opposite from arm extension 38 , if of sufficient magnitude . a further feature of the invention may be noted as residing in the presentation of extension surface 39 against the palmer surface of the wearer &# 39 ; s ring finger 20 . because of the relatively narrow transverse width of such surface 39 , it is observed that surface 39 presses lightly into the fleshy palmar surface of the finger , as depicted in fig2 in order to provide additional force resistant to twisting movement of the ring about the finger of the wearer . thus , not only does the device securely affix the ring to the wearer &# 39 ; s finger but also most desirably limits objectional twisting movement as might otherwise be prone to occur with such a top - heavy ring at that shown with its large heavy setting 11 . the device of the invention is most easily applied to any conventional ring , obviating the cutting away of the conventional shank and replacement with an adjustable shank or other cumbersome and objectionable modifications mandated by prior art efforts to solve the problem of effectively reducing the size of the ring opening upon placing the ring upon the finger of the wearer . a device of the present invention may be easily fixed to the ring by even relatively unskilled jewelers and in very short time , with consequent savings to the customer , as opposed to manifestly cumbersome , complex and intricate apparatus of the prior art . moreover , it is a relatively simple matter should the device need to be removed , to detach the hinge members 30 , 31 from the ring shank , whereupon subsequent polishing of the shank surface returns the ring to its conventional character , leaving only the tiny indentations 50 on the inner surface of the shank which are not visible when the ring is worn . although the foregoing includes a description of the best mode contemplated for carrying out the invention , various modifications are contemplated . as various modifications could be made in the constructions herein described and illustrated without departing from the scope of the invention , it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative rather than limiting .
