TOOTHBR'USH CONSTRUCTION.

Application filed September 8, 1923.

To all "117710111 it may concern:

Be it known that 1, CHARLES ARGHIBALD STONEr-IILL, a citizen of the United States, and a resident of Glencoe, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Toothbrush Construction, of which the following is a full, clear, and exact description.

My invention relates to "improvements in tooth brush constructions, and it consists in the combinations and arrangements herein described and claimed.

rrn object of my invention is to provide a tooth brush having in the handle thereoct a tooth pick so disposed that the pick may be at any time withdrawn for use.

A further object of my invention is to provide a device of the type described in which the pick is so disposed as not to interfere with the use of the tooth brush proper.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be par-- ticularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings forming part of this application, in which Figure 1 is a side view (it a tooth brush constructed according to my invention, a portion of the brush being shown in section,

Figure is a plan view ot' one end of the bran I handle shown in Figure 1,

Figure 3 is an enlarged face view of the tooth pick,

Figure 4 a View similar to Figure 2 showing a modified form,

Figure 5 is a view similar to Figure 2 showing another modified form, and

Figure 6 is a section along the line 6 4; of Figure 5. V

in carrying out my invention I make use of a tooth brush having bristles 1 and the handle The latter is designed to carry a tooth pick 3. This pick may be of any suitable material, such as wood, celluloich shell, hard rubber, or the like. It is pret' erably provided with a head portion 4, and is pointed as shown in Figure 3.

Serial No. 661,633.

ihe body portion of the handle is pro vided with a slot 5 extending inwardly from one end thereof. In Figures 1 and this slot is shown as being disposed substantially along the central axis of the handle, that is, midway between the sides and midway between the upper and lower edges. The head it limits the movement of the tooth pick in the slot.

ln Figure l- I have shown the tooth pick as being carried on one side of the central line so as to provide for an opening 6 by means of which the tooth brush may be hung on a hook.

in Figure 5, which is a modified form, a slot '7 is shown running from the end of the handle toward the brush. This slot is i -shaped in cross section as is shown in l' igure (i so that the tooth pick 3 when placed thereon is seen from above.

in each or the terms the tooth brush will have with it at all times the tooth pick so that the thorough cleansing of the teeth can be accomilished by "the pick and the brush after which the pick can be cleansed, and then replaced in the slot in the handle. where it will remain.

'l 1e head i: not only limits the movement oi the tooth pick into the slot. but it pro vides a means lor readily pulling out the tooth pick.

l clai" A tooth brush constriution cinnprising a curved handle having a slot in one end th ir-ail". the longitudinal axis of said slot be curred in conformity with the curvature of the handle. and a curved tooth pick 21l"!:!1(,". to slidahly enter the slot and to l'rif-tioiially ei with the walls of the slot so as to normally be held in place. said tooth pick having a head provided with a shoulder arrange-d to engage with the end oi? the handle and to limit the movement oi the tooth pick inwardly, said head being oi less width than the width of the handle, whereby the head is rendered inconspicuous.
