SPECIFICATION forming part of Letters Patent No. 725,462, dated April 14,1903. i Application led September 25, 1902.. Serial No. 124,764. (No model.)

v is a full, clear, and exact description.

The purpose of this invention isto provide means especially adapted to be yattached to' tooth-brushes and by which silk or the like may be held taut, so as to be useful in cleaning the teeth.

Tothis end the invention comprises means for carrying the silk in or on the handle of the tooth-brush or other supporting part and a bow for holding a part of the cord extended in position to be used.' The invention also involves various minor features of construction and arrangement of parts, which will be fully described hereinafter.

This specification is an exactdcscription of one example of my invention, while the claims deine the actual scope thereof. -v

Reference is to be had to the accompanying drawings, forming a part of this specicatiom' in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the invention. Fig. 2 is a section on the line 2'2of Fig. l. Fig. 3 is a bottom plan view ofthe ferrule or band which secures the thread-holder in place, and Fig. 4 is an inner View of the thread-reel and the holder therefor.

a indicates the supporting part, which may be assumed to be the handle of the toothbrush. The invention ispreferably applied to the end of the tooth-brush handle, in which connection it will be very conveniently situated. It may, however, be used in other con# nections, as will be obvious.

The bow comprises a shank b, which is formed in the end of the handle ct and carries the bow proper, formed of theback h', the inner end h2, and thewouter endrb, these ends extending 4transverselyof the'back b and the end b2 havingan eye b4 therein,through which the thread (indicated at c) is passed. The end b3 of the bow has a stud b5, adapted to have the thread turned around it, and a notch h6 is formed in the rear portion of the end b3, this notch not only serving as a chock in which to place and secure the end of the shown in the drawings.

thread, but also forming sharp edges on which the thread may be cut, so as to sever the used or soiled portions of the thread from the unused portions. Y

In the handle a is formed a cavity a', and over this 'cavity is placed a coverfplate d. This plate "has an .inwardextension dlying in'a slight recess formed inthehandle ct, adjacent to thecavityrct'fand fastened securely to the inner side of said plateis areotangular frameie, in which is mounted the piu f of the The frame e has an outward ex silk-reelfz, tension e2 located opposite the extension d and lying in a slight recess in the handle a, adjacent to the outer end of the cavity a. From this extension projects a Vpliable lip e', serving to hold the band or ferrule in place.

g indicates the clamping band or ferrule,

which is slidable on the handle ct, so as to cover or uncover the plate d; By this means the plate is secured in place, and by moving the band g off of the plate said plate, with the reel f2, may be'detached. The band g may be moved by bending down the pliable lip e and secured by bending said .lip upward, as This band g is formed with a slot or notch g therein to permit the passage of alat'ch h,which latch is pivoted at the point It'` to the frame e and projects through a slot in said frame, as best shown in Fig. 4, so as to engage the notched periphery of the reel f2. v

h2 indicates a spring, which is applied to the latch h to hold the same normally engaged with the reel. By pressing outward (to the right in Fig. 2) the exposed end of the latch the inner end of the latch Awill bedisengaged Vfrom the reel, and the reel will This will permit the then be free to turn. cord to be drawn out of the handle, and when a sulicient length of cord has been Withdrawn the latch h will be allowed to return toits active position, whereupon the reel will be held immovable. The end portion of the cord should then be. drawn. tight between the ends b2 and b3 of the bow, and the extremity of the cord may then be fastened by turning it around the stud b5 and fastening it 'in the chock lr6. i

In the use of the invention the parts are adjusted as shown in Figs. l and 2, and the cord is used on the teeth in the usual man- IOO ner. W'hen the cord becomes worn or it is desired to use a new length of cord, the latch 7L should be pressed to release the reel and the desired length of cord be drawn out. The latch should then be allowed to return and the cord drawn tight between the ends of the bow, after which the end should be fastened in the manner before explained. When all the cord is drawn from the reel, the band g should be removed, the frame e taken out of the socket, and a new reel putin place of the old one.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie Within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A dental silkholder, comprising a body member, means attached thereto for holding a length of the silk in operative position, a reel mounted on the body member and having a notch therein, and a latch movable toward and from the notched portion of the reel and normally engaged therewith.

2. A dental silk-holder, comprising a body member, means attached thereto for holding a length of silk in operative position, said body member having a cavity therein, a frame set into the cavity, a reel mounted in the frame, and releasable means for holding the reel against rotation.

3. A dental silk-holder, comprising a body member, means attached thereto for holding a length of silk in operative position, said body member having a cavity therein, a frame set into the cavity, a reel mounted in the frame, releasable means for holding the reel against rotation, said frame having a pliable lip, and a band placed over the cavity in the body, for the purpose specified, and engaged by the lip, said lip serving to hold the band in place.

4. A dental silk-holder, comprising a recessed body member, means carried thereby for holding a length of silk, a frame set into the recess of the body, means for holding the frame removably in place, a reel mounted in the frame, and a latch mounted in the frame and normally engaged with the reel to hold the same against rotation.

5. A dental silk-holder, comprising a recessed body member, means carried thereby for holding a length of silk, a frame set into the recess of the body, means for holding the frame removably in place, a reel mounted in the frame, a latch mounted in the frame and normally engaged with the reel to hold the same against rotation, said means for holding the frame in place comprising a cover-plate placed over the recess and secured to the frame, and a band embracing the body and cover-plate.

6. A dental silk-holder, having a body, means thereon for holding a coil of silk, and a bow attached to the body, said bow having at its outer end a stud adapted to have the silk wrapped around it and a notch adjacent to the stud 'to carry the end of the silk and facilitate breaking off the same.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
