UNITED STATES CHARLES E. HUDSON, OF LEOMINSTEB, MASSACHUSETTS.

DENTAL FLOSS HOLDER.

Application filed February 8, 1923. Serial No. 617,717.

To all whom it may concern:

Be it known that 1, CHARLES .ErHUDSON,

a citizen of the United States, and resident of Leominster, county of Worcester, and Commonwealth of Massachusetts, have invented an Improvement in Dental Floss Holders, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

' This invention relates to dental floss holders and aims to provide a novel holder adapted to be carried in the pocket and having, among others, the advantages hereinafter pointed out.

In the drawings of the particular embodiment of my invention described and claimed herein,

'Referring first to Figs. 1 to 5, my novel floss holdercomprises a preferably curvilinear case 1, comparatively shallow and with an upturned flange 2 on its edge, and adapted to be readily carried in the pocket or hand bag.

On the edge of the holder or case 1, at any suitable point, are providedtwo cars 3, 4, which are drilled to receive the inner end of a curved floss holding arm or support 5 which preferably conforms generally to the outline of the case 1, and is adapted to swing in said ears to desired operative position. The cover 6 has a flcnge 6 which carries an ear 7 whichfitsbetween the ears 3, 4, and is also drilled to receive the end of the arm member 5.

The inner end of the arm 5 between the two ears 3, 4, is drilled, notched or cut away horizontally at 8, Fig. 5, opposite an aperture 0r slot 9, Fig. 4, in the ear 7 The outer end of the arm 5 may be provided with a small nut 10 mounted to turn up against a boss 11 on the arm, to lock the floss end between the boss and nut to anchor the same.

The silk or dental floss, Fig. 2, may be placed within the case 1, in the form of 'a" To use the floss, a suificient length having been withdrawn from the case, the arm 5 is first turned to the left, see Fig. 3, which acts, Fig. 6, to pinch or compress the floss between the outer face of the inner or hinged end of the arm 5 and the inner face of the ear 7, and to lock it securely. The opposite end of the floss may then be secured or anchored to the outer end of arm 5 by winding it once or twice-between the nut 10 and the boss 11 and turning up the nut. The floss is thus tightly drawn between the two ends of the arm 5, Fig. 3, and may be conveniently used as-desired.

After use the end of the floss is unwound from the outer arm .end, the arm is preferably swung back to normal position-and the thread carried down beneath a cutter 15 struck up from or otherwise formed on the case 1, the used portion of the floss severed passed through a slot in the'flange and looped as shown, and the floss passes through a slot in the flange 2, thence through a cut away portion, slit or hole on the arm end at 17, seeFigs. 7 and 10, as in the case of Figs. 5 and 6.

When the arm 5 is turned upward or away from the case as in Fig. 8, the floss is com pressed betweenthe arm end and the ear 7 as before. The outer floss end can then be secured to the outer arm end, which in this case comprises a series of coils of wire 18 about the arm end, bothv ends of the wire being preferably secured to the arm end.

The floss end can be readily forced between the-adjacent coils and held securely.

In Figs. 11 to 13 is illustrated a second modification wherein the arm end 5 is pivoted in an ear 19 on the inner face of the upturned flange 2 of the case 1. The ear, Fig. 13, has an aperture or slit through it at -20 registering with any convenient opening 21 in the arm end 5 when the arm is in inoperative position, Fig. 11. When the arm is turned to operative position, Figs. 12, 13, the freefloss end is carried half a turn around by the turning end 5 and is forced out of its plane of travel and is compressed orcrowded and locked between the end 5 and the 'BELI.19. The free end of the floss extended through the outer end of the aperture 20 is then secured to the outer arm end. as in the case of Fig. 9, or in any other way desired, as by forcing it into the split arm end, Fig. 14, or by providing the arm with a'pair of convex disks 22 Fig. 15 between which the floss end is anchored or gripped. The cover flange 6 is slotted to receive the arm 5 and, to make room for the swinging action of the lnturned arm end 5 in the constructlon shown, Figs. 11, 12, the

flange 2 may be cut away for a short distance along its upper edge, see Fig. 11, the

inturned end 5 and the cover 6 of the case turning with the arm and permitting the latter to work freely. I

. In this construction pressure may readily be exerted on the boX and cover 6 by the fingers efficiently to hold the arm flrmly'in position.

As illustrated in Fig. 16, the arm is pro- .videdwith a few' turns of flat wire, the outer face of which isV-shaped. The floss will be firmly held between the successivecoils of this wire.

The floss in either of theforegoing cases is held sufficiently tightly to permit its application to the teeth and use without especially holding it for that purpose.

My invention is not limited in all respects to the particular features of construction shown.
