NETED STATES CLASP FOR DENTAL MIRRORS.

Application filed June 13, 1923.

T aZZ whom it may concern Be it known that I, E'rsUJI E. Mariana, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Clasps for Dental Mirrors, of which the following is a specification.

This invention relates to improvements in means for maintaining dental mirrors in compact assembled relation, whereby they may be relatively detached to facilitate pen sonal inspection of the teeth, and internal mouth. I

A further object of this invention is the provision of a relatively simple and practical type of clasp for the type of dental mirrors set forth in my co-pending application,

' Serial No. 468,331, filed May 10, 1921.

A further object of this invention is the provision of a novel clasp device embodying detachable parts which may be mounted upon different articles so that the articles may be maintained in compact detachable relation.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevation, partly in section of dental mirrors held in assembled relation by the novel clasp means.

Figure 2 is a front elevation of a dental mirror showing a portion of the clasp as a permanent part thereof.

Figure 3 is a transverse cross sectional iew, taken substantially on the line 33 of Figure 1..

Figure 4 is a perspective view of the parts of the clasp as shown in Figures 1, 2, and 3.

Figure 5 is a modified type of clasp.

Figure 6 is a perspective view of the clasp details illustrated in Figure 5, showing the same disassembled.

Figure 7 is anovel and further modified form of the improved-clasp.

In the drawing, wherein for the purpose of illustration is shown but the preferred embodiment of this invention, the letter A may generally designate the preferred form of clasp, which may include sections B and C for respective connection'upon the dental m r ors, D a d E.- The fi t modified form Serial No. 645,219.

of clasp F may include interengaging sections G and H and the second modified form of clasp K may include sections L and M.

Referring to the preferred clasp A, the section B as well as the section C thereof is formed of stamped sheet metal or any other analogous material, and these sections are respectively mounted upon the hand grips or shanks 11 and 12 of the dental mirrors D and E. The mirrors D and E are of the type specifically set forth in my copending application above referred to and each include a circular disc shaped frame 18, both of the same diameter, supported at the upper end of the hand grip shanks 11 and 12; said frames 13 being arcuately flanged, as at 1 1, to receive reflecting elements 15 therein. The clasp means A is mainly provided to maintain the mirrors D and E in a stable relation, so that the arcuate flange portions 1 1 of said mirrors are in abutting relation to enclose the reflecting surfaces of the reflector elements 15 in a compartment, so that dust and other foreign materials may not settle upon the reflecting surfaces when the mirrors are not in use.

The section B is preferably formed of a single piece of material and of uniform height about the same. It is formed about the shank 11 of the mirror D as to be rigid thereon; the ends and 21 being bent about the shank 11 to abut, as on a oinder line 22. The section B when thus disposed about the shank 11 provides a substantially oval shaped opening 24 through which the shank 11 is disposed, thus providing an article grip portion, so to speak. At the side of the article grip section B, opposite the joinder line 22, an outstanding crimp or socket portion 25 is provided,which provides a socket opening 26 opening at each edge of the section 1), into which an attaching tongue 28 of the section C may fit. The socket opening it; is not solely provided by the section B but intermediate the outstanding portion 25 and the facing surface of the mirror shank 11, substantially as is illustrated in Figure 3 of the drawing.

Referring to the section C, the same proferably includes an attaching portion 30 preftially parallel spaced relation at a side of the attaching portion 30. This section C is assembled in fixed relation upon the mirror shank 12, and is adapted to have the tongue 28 detachably disposed within the socket 26 of the section 13, substantially as is illustrated in Figures 1 and 2 of the drawings, whereby the mirrors D and E may be maintained in an assembled relation, substan tially in accord withthe invention set forth in my copending application above referred to.

Referring to the modified form of this invention, as illustrated in Figures 5 and 6, the sections G and H are similarly formed respectively to the sections B and C above described, except that the sections G and H are adapted for mirror handles of "special shape. To this end, the section B. intermediate its ends is provided withthe socket portion 35, outwardly from which the arms 36* and 37 extend; said arms 36 and 37 preferably being concavo-conveX to provide the substantially concaved facing pockets 38 and 39' respectively therein for receiving the shank 11 of a mirror D. In this type of section G, the end edges 40 and ll of the arms 3 n and 37 respectively, are in spaced relation; said arms 36 and 37 acting in the nature of resilient arms to grip the shank 11 so that the section G may maintain a fixed relation upon the shank 11. The socket portion 35, when the section D is upon the shank 11, of course provides a socket opening 36 into which the tongue 37 ofthe section H may extend substantially after the manner above described for the preferred embodiment of this invention.

The section H similarly includes the concavo-convex arms 42 and 48', respectively providing facing pockets 4% and 15 for receiving the shank portion 12 of a mirror-E therein. The end edges 17 and 18 of the arms 42an'd 43 respectively, of course, are in spaced relation, at the outside of the shank-12, substantially as is illustrated in Figure 5 ofthe drawings.

Referring to the further modification of this invention'as illustrated in Figure 7, and which type of'clasp' is prefe -ably adapted for the better grade of mirrors, in which it is not desired. that the section have a crimped'socket. lhe section L of the clasp K preferably includes an inner band 50, which is-clainped about a mirror shank- 51 to conform to the configuration of the same; the. marginal edges at the ends of the band 50 being spaced at the inside of the shank 51. An outer clamping band 55 is also pro- I vided as a part of the section L, the ends 56 and 57 thereof being arcuate and clamped over the ends of the bands 50, so that the intermediate portion of the band 55 extends across the space designed by the end edges 52 and 53 of'the band 50, so that a socket opening 58 between the intermediate por tion of the band 55 and the inside of the shank 51 is provided, for receiving the tongue 59 of the section M which is clamped to the shank 60 of another mirror. It is to be noted that the end edges of the arms 56 and 57 are spaced for a considerable distance on the outside of the band 50, so that it can readily .be seen that the section L readily adapts itself to various configurations of mirror handles. 7

Referring to the section M, the same includes an inner band 62 which may be of any configuration to be snugly placed about the shank 60, and upon the upper marginal edge of which the tongue 59 is provided, much in the same manner as above described for the preferred embodiment of this invention. An outer band (35 is also provided) as a part of the section M, the ends 66' and 67 of which grip about the band 62 at the ends of the latter and the intermediate portion of which band is disposed about the band 62 at the tongue side thereof. The endedges 69 and 70 of the band 65 'are'spaced at the outside of the band 62 for any desired dis stance. The tongue 59 is of course detachable from its socket opening 58, .mu'ch in the same manner as above described for other forms ofthis invention.

From' the above description of the improved dental mirror clasp, it is obvious that the mirrors'may be maintained in a precise and defined relation when assentbled, in accordance with features ofthe arrangement set forth in my copen'dingapplication above referred to.

Various changes ini the shape, size'a-nd arrangement of parts may be made to the form of invention herein' shown and described, without departing from the spirit of the invent-ion or the scope of the claims.
