Application September 18, 1946, Serial No. 697,726

9 Claims.

This invention relates to combs, brushes and the like and more particularly to combs of the variety having removable teeth so that when they become worn or broken they can be replaced with new teeth.

It is an object of the present invention to provide a handle and rod arrangement for a comb having removable teeth wherein the teeth can be removed from the rod at the end thereof removed from the handle and without having to remove the handle therefrom and by simply releasing the handle from the rod.

. It is another object of the invention to provide a comb structure of a type having removable teeth elements which can be fitted into a brush body Without incurring or consuming great space or requiring that the body portion of the brush be enlarged.

According to the invention, a handle contains a rod and means for adjusting the rod relative to the handle. Teeth elements are disposed on the rod opposite to the handle end thereof and means is provided whereby the teeth elements will be retained against removal from the rod. This means is an end formation from which the rod is released or in another form of the invention an end formation which is removable from the rod end. In both forms, the teeth elements are removed from the rod at the end thereof removed from the handle.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. l is a side elevational view of a combined brush and comb with the teeth in place and ready for use.

Fig.2 is a transverse cross sectional view taken along the line 2 2 of Fig. 1 looking in the direction of the arrows thereof.

Fig. 3 is a longitudinal cross sectional view taken generally along the line 33 of Fig, 2 looking in the direction of the arrows thereof.

Fig. 4 is a fragmentary longitudinal cross sectional view of the brush end of the device when the rod has been slightly withdrawn to permit either the removal. or the addition of tooth elements.

Fig. 5 is an elevational view of a modified form of comb having means for permitting the removal 2 of the tooth elements from the end of the rod remote from the handle.

Fig. 6 is a detail perspective view of the rod removed from the handle which serves to retain the teeth.

Fig. "7 is a detail perspective view. of one of the end formations between which the teeth are retained on the rod.

Fig. 8 is a perspective view of the opposite end formation having means for securing the same to the rod after having been turned through an angle.

Fig. 9 is a cross sectional View taken through the end formation shown in Fig. 8 as along line 9--9 looking in the direction of the arrows thereof.

Fig. 10 is a cross sectional view taken through the comb as shown in Fig. 5 along the line lD--l 0 thereof looking in the direction of its arrows.

Fig. 11 is a longitudinal cross sectional view of the comb shown in Fig. 5.

Fig. 12 is a detail perspective view of an individual tooth element such as used with both forms of the invention.

Referring now to the figures, 2| represents a combined brush and comb comprising a brush and comb handle 22 having a body portion 23 integral therewith. Brush clusters 23 are secured to the body portion 23. The handle portion 2| has a hole 24 extending therethrough and in communication with a slot 25 extending upwardly from the bottom face of the body portion and throughout substantially its full length except for an endformation 26 serving as a stop for tooth elements 21 (Fig. 12) adapted to be disposed in the slot 25. Extending through the hole 24 is a tooth-retaining rod 28. This rod extends into and throughout the length of the body recess 25 and for that portion of the rod which extends within the recess 25 it has alongitudinally-extending guide 29 which cooperates with key way slots 3! of the tooth elements 21 whereby to retain the tooth when upon the rod against rotation and disalignment with respect to one another. The end of the rod 28 when in its retaining position extends into a recess or depression 32 of the same section as the rod whereby to prevent the rotation of the rod relative to the body portion 23.

The opposite end of the recess 25 has a slot 33 for receiving the opposite end of guide 29 and serves also to prevent rotation of the rod 28. The guide 29 is slidable in the slot 33 as the rod 28 is axially adjusted to release or receive tooth elements.

The handle 2| has an internally threaded fer- 3 rule 35 embedded therewlthin adapted to receive a slit externally threaded sleeve 35 adapted to rotate in an annular recess 35 on the rod 28. Since the ferrule 34 is fixed to the handle any rotation of the sleeve 35 therewithin will effect axial adjustment of the sleeve and of the rod 28 within the handle and body portions. The sleeve 35 may have a radially-extending flange 31, and a cap 39 witha screw driver slot can be secured over the end'facethereof by rivetsM. This cap 39 receives the end of the rod 28.

As the sleeve 35 is turned through the agency of the cap 39 the rod 28 will be withdrawn from the recess 32 of the body end Edasillustrated in Fig. 4. This is sufficient to permitithe removal of the teeth 2'! for replacement or cleaning;

When the full number of tooth elements have.

been added to the rod the sleeve 35 can be rotated in the opposite directionand the rod end-returned to the recess 32 to secure the tooth elements in place upon therod; A spring washer la can be disposed on the rod to make certain that the recess is filled throughout its length with tooth elements andto prevent anyslight looseness between tooth elements.

Referring now to the form of the invention shown in Figs.- 5 to 12 iilrepresents a rod having a threaded end 46 and a tooth element receiving portion 'll witha guide extendinglongitudinally therealong. The guide hlterminates short of end 590i the rod; On the end llBare-pins 5 l only one being shown, butthe same being diametricallyopposite one anotheron' the rod'over which an end formation 52 is" 'slid for engagement with the rod. This end formation has a hole 53 therein'forreceiving the rod end'and slots 54 for receiving the pin projections 5i. The slots54 extend to an annular recess 55 which will permit the end formation to be'rotat'ed'so that the'slots- 5d are out of registry with the pin 5| andwherebythe end formation canhe retained on the rod against axial'displacement.

Adjacent the threaded end of the rod 45 is a handle sleeve 56 having a ferrule Blonits inner end for engagementwith a tooth element stop 5.8, which is recessed at 59 to receive one end, of guide 68 On the. threaded end 46- is a threaded sleeve 6| having a hQadpOrti n-GZ for turning the same and for causing, as the sleeve is turned, the tightening of'the, end formation 52-. against teeth elements zldisposedupon the rod'45; The handle 56 is axially slidably mounted onitsrespeotive end of the rod 45; and'the sleeve 5! of. the head portion 62 is rotatively received in, a complementary recess formed in the outer end of the handle 56,.

If it is desired to remove teeth elements 21, from the portion 4T of the red, the sleeve 6| is loosened to release the end formation 52. The end formation 52 is turned uponrthe rod so that its recesses 54 register with the pins 5| andthe end formation 52 is then axially removed. from the rod. The pins 5| should then be removed to permit the removal of' the tooth elements 21. To assemble the tooth elements andmake the. comb rigid, the operation is reversed.

While I have, illustrated and described the preferred embodiments of'my inventionit is to be understood that I do not, limit myself to the precise constructions herein disclosed andt-he right is reserved to allchanges and modifications coming within the scope of the invention as defined in the appended claims;
