Application filed March 3, 1921.

To @ZZ whom' it muy concern:

Be it known that l, Emmer C. Lroiv, a citizen of the United States, residing in Long Beaclnin the county' of Los Angeles and State of California, have invented new and useful Improvements in Brushes; and declare the following to jbe such a' full, clear, and exact disclosure of the invention that anyone skilled in the art to which is appertains may make and use the same.

rl`his invention relates generally to brushes, and particularly to toilet brushes, such as hair, clothes, and the like; the specific object of the invention being to provide a brush of this character so constructed that it may be easily and conveniently folded into a compact case, suitable for`A carrying in the pocket or baggage, and easily and quickly 'adjusted for use.

The Vimproved features embodied in the construction may be broadly stated as comprising a plurality of bristle supports, revolubly mounted Within a case, which also serves as the back of the brush, and interconnected so the bristles can be either` foldable within the'case for carrying, or extensible therefrom for use.

The details of construction and operation of the invention will be more fully set forth in the following specification, reference being made therein tothe accompanying drawings, forming a part thereof, and in whichfig. 1 is a plan view of the brush showing the bristles folded within the case, and with the cover removed; F ig. 2 is a longitudinal sectional elevation of the same taken on the line 2-2 of Fig. 1; llig. 3 is an end elevation of the device as shown in F ig. 2, the view being taken as indicated by the line 3MB of Figi 2; Fig. 1.- is a view similar to Fig.V 8, yonly taken as indicated by line ll of Fig. 2; F ig. 5 is an enlarged fragmentary plan View of one of the bristle supports; Fig. 6 is a transverse vertical section of the same, being taken as indicated by the line 6 6 of Fig. 5; and Fig. 7 is a fragmentary sectional view similar to Fia. showing the bristles in operative position.

Referring now to the drawings the numeral 10 designates generally the case in which the brush Velements and their operating inechanism are enclosed, consisting of a bottom portion 11, and a cover or removable topI portion 12. This case may be advantageously constructed inthe con- Specncation of Letters Patent.

ligpguration shown in the drawing, and may Abe formed of metal or other suitable materiaL t Both the bottom and top portions are similarly formed each with -ends and corners rounded, so as to present a neat and .symmetrical outer appearance, and, also, so Vthe bottoni portion can be conveniently grasped by the hand, as a baci: for the l13 for holding the two portions together when the cover is down. A spring catch 15, is mounted, by means of a rivet 1G, to the inner face 'of the lower member 11, at

4itsopposite end; the said catch having a detent 16=l adapted to engage a notch in the cover 12 to hold the two members of the case together at this end. A button 17 on the catch extends through an aperture 18, in the lower portion 11, this being provided as a means for pressing' the catch 15 baci: and disengaging the detent 16 from the notch when lit is desired to remove the cover 12. For convenience, a mirror 19 may be removably carried inside the cover 12, grips 2O being provided therein for ren taining this mirror in place. is the cover 12 is adapted tok be entirely removed from the lower portion 11 when the brush is in use, the mirror 19 need not be disengaged for use from the cover 12 unless desired.

The brush proper comprises a plurality of cylindrical bristle supports 21, each having shafts 22 extending axially through their centers and extending from their ends, by means of which they are revolubly journaled :in longitudinal supports 23 in the lower portion 11. The supports23 may be constructed of thin sheet metal, each having their ends bent as at 211, by means ofr which ends they are secured to the sides of the lower portion 11, so the portions 23 will `extend outwardly ash'ort distance/therefrom, as clearly shown in -F ig. 1. The ends 24 may beV secured to the side 25 in any suitable manner by soldering orrriveti'ng. It willbe noted by referenceto Fig. 2 that the bearing supports 28 are so mounted in the lower portionV 11 that the bristle supports will be mounted with their peripheries extending y a very short distance above the upper edge of the lower portion 11; so that when the cover 12 is removed and the bristles are extended to operative position, they will project well above the upper edge of the lower portion.

The cylindrical bristle supports 21 are preferably constructed of wood, or a like material, and are formed by cutting away a portion of the peripheryto form a flat surface 26 from end to end thereof; a longituvcenter of the supports 21 may be bored out from end to end to accommodate and receive the shafts 22, the aforementioned means of constructing these elements is preferable for the reason that it combines a simple method of manufacture, and also enables the shafts 22 to be rigidly secured Within the support 21 in a very simple and efficient manner.

The bristles 80, being of any desired length, are secured to the supports 21 by lforming a plurality of transverse grooves 31 in the co-planar surfaces 26, into each of which several of the bristles 30 are laid, and secured therein by means of cement or glue, the material 29 used for securing the shafts 22 in the supports 21 preferably being used for this purpose, and the bristles being applied at the same time the shafts 22 are set. After the bristles BO have been set in the transverse grooves 31, as shown in Fig. 5, and while the cement 29 is still soft, a strip 82 of fabric or other suitable material is then laid over the surfaces 26, to further in sure a rigid mounting of the bristles 30, this strip being retained by the material 29.

lIt will be noted from an examination of Fig. 1 that the bristle supports 21 extend almost entirely across the lower case portion 11, being suiiiciently shorter to permit being mounted in the supports 23. Each of the supports 21 are mounted in the supports 23 as near ,togethery as possible, only suiiicient space being left between them to admit of their operation to move the bristles 80 from operative to inoperative position, and vice versa,as shown in Figs. 2 and 7. When the Y supports 21` are rotated to'bring the bristles "30 Within the case, or intoinoperative position, the bristles of each adjacent support will overlap and rest upon the top of the `bristles ofthe next adjacent support, as

shownV in Fig. 1. And in order that the brush as a Whole may occupy ammimum of Leidens space Within the portion 11, the supports 21, together with their bristles 30, are mounted so an equal number will be disposed on either side of the center` line C of the case, the bristles on either sid-e of this center line being adapted to point towards each other when in inoperative position as shown in Fig. 1. To admit of this construction, the bristles 3() on vthe two center supports 21' are mounted in relatively staggered relation so that the bristles of one will extend between the bristles of the other when in such inoperative position.

The supports 21 are all interconnected to be acutated simultaneously, and rotated an equal amount, by means of cranks 33 secured to one end ofthe shafts 22, the ends 3/1 thereof extending through apertures 35 in typical connecting rods 36 and 37.- A pairof intermeshing spur Gears 38 and 39 are rigidly secured to corresponding ends of shafts 22 of the two adjacent center supports 21, @ranks d0 and d1, respectively, radially mounted on the gears 38 and 39, each have lower ends L12 extending through perforations 4:3 in the connecting` rods 36 and 37.

This actuating mechanism is made manually operable by means of a thumb lug-141, formed integral with the'connecting rod 37,

Vand extending upwardly therefrom toa point above the top of the supports 21, but termi* nating at a point below the ends of the bristles 30 when they are extended upwardly in operative position; this thumb Vlug liet being adapted to be engaged by the thumb or finger to move the connecting rod 37 longitudinally ofthe case portion 11. it is clear that such longitudinal movement of connect-- ing rod 3'? will, through the medium of the v cranks 33, rotate the supports 21 to bring the bristles 30 into operative position, as l have shown in Fi g. 7. The crrnlr i1, connecting with the spur gea-r 39, and the latter cooperating with the spur gear 38 to transmit the same amount of'movement to the connecttive position to hold the mechanism in that position.

icaY

In operation the cover 12 is removed from the lower portion 11, by releasing the demitting it tov pivot on the tongues 141 to swing clear of one end of the lower portion, after which it is moved longitudinally and the tongues lerwithdrawn from the slotsl.

Vtent 16 from engagement therewith, and pera' rection indicated by the arrow in Fig. 2; this movement rotating the supports 21, through the medium of the connecting rod 37 and the cranks 33, and also rotating the spur gear 39, through the medium, of the crank 4l, which in turn causes rotation of the gear 38, all in the directions indicated by the arrows in Fig. l; the latter causing rotation of the supports 2l through the medium of the cranks 33 and connecting rod 36, in the direction indicated by the arrow. These movements will move the bristles from the position shown in Fig. l to the position shown in Fig. 7, or from inoperative to operative position and ready for use. It is obvious that movement of the thumb lug le in the direction opposite to that indicated by the arrow in Fig l, will move the bristles from the position shown in Fig. 7 back to that shown in Fig. l, when the cover may be again attached for carrying or packing.

lVhile I have here shown and described a preferred embodiment of my invention, it will nevertheless be understood that I reserve the right to make any changes or moditications in structure which may appear to those skilled in the art and which come within the scope of the appended claims.

Having described a preferred form of my invention, I claim:
