Application filed January 16, 1926. Serial No. 81,837.

My invention relates to. brushes. d An important objectv of the invention is to provide a brush which may be kept in a' sanitary condition and is well adapted for I use by tourists or the like.

A further object of the invention is to a part of this specification, and in which like M numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of a brush embodying my invention,

Figure 2 is a central longitudinal sectional view through the same, Y

Figure 3 is an end elevation of thesame,

Figure 4 is a transverse. section taken on line 4 4 of Figure 2, with the brush element in the closed position,

Figure 5 is'a similar view with the brush element in the open osition, and

Figure* 6 s-an en arged section through the inner end of the brush element, and associated elements, 'parts being shown inelevation.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of m invention, the numeral 10 designates a brush element as a whole, em-

- bodying a brush head 11, which is generally semi-circular in cross section, and carries bristles 12, which are arranged in a semi-circular group. The bristles and brush head constitute 'a cylinder. The brush head 11 is provided upon its outer curved face with a casing section or liner 13, having ends 14. y The brush head is rigidly mounted lin this casing section. The brush head 11 and casing section 13 are rigidly mounted upon a rock shaft 15, as

v shown. y

The numeral 16 designates a semi-cylindrical cover or casing section having ends 17 and 18. The end 18 hasy a tubular boss 0 or bearing 19, rotatabl receiving the cylindrical end of the roc shaft 15, and this boss may be covered by a cap 2l, having screw-threaded engagement therewith. The end 17 has a circular opening 22, to re- 5 ceive the cylindrical portion 23, of the shaft 15, the rear portion 24 of the shaft, outwardly of the cylindrical portion 23, being polygonal in cross section.

Splined upon the rear portion 24 of the rock shaft, to slide thereon and turn therewith, is a tubular block 24, having forwardly diverging arms 25, rigidly attached thereto. These arms are rigidly attached to a transverse strip or bar 26, provided at its ends with rearwardly projecting extensions or ears 27. The transverse bar 26 has an opening for slidably receiving the polygonal portion 24. y

The transverse bar 26 carries forwardly projecting locking pins 28, rigidly attached thereto, adaptedlco move into openings 29 in the end 17, and to alsosenter openings 30, in the inner end of the brush head 11, and end 14. A

Clamped to the portion 24 of the rock 4shaft isa collar 31, engaging a compressible coil spring 32 confined between it and the bar 26. This collar is arranged within the arms 25. The numeral 32 designates a handle, the forward end of which diverges forp wardly, providing a housing 33, for receivf ing the portion 24 and associated element. The ears 27 are arranged-within this housing and are rigidly attached thereto'by means of screws 33 or the like.

The operation of the device is as follows:`

When the brush head 11 is turned within the cover or casing section 16, as clearly shown in Figure 5, the bristles 12 will be exposed, for use. When thev brush head 11 is in .this position the openings 29 and 30 will register and the pins 28 will enter these openings, thus locking the casing section or cover 16 and brush head 11, aga1nst relative turning movement. The handle 32 may be drawn rearwardly with respect to the casing section or cover 16, and this will withdraw the locking pins 28 from the openings 29 and 30', and the forward end of these locking pins may slide upon the end 17, while the handle is employed to turn the brush head for one-half of a revolution. When this is done, the bristles 12 will occupy a position within the casing section or cover.

16, Figure 14, and the locking pins 28 will again enter the openings 29 and 30 and the `brush head and cover are locked against relative turningmovement.

It is to` be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same and that various changes in the shape,

otally supported thereby, a brush head,

mounted upon the rock` shaft to beA turned upon its longitudinal axis by said rock shaft a handle slidably and non-rotatably mounte upon the rock shaft, and means to lock the brush head and the cover together, said means being actuated by the sliding movea cover havlng one slde open, a rock shaft ment `of' the handle.

2. In a device of the character described, a cover, abrush head to turn within the cover, a rock shaft mounted in the cover and -rigidly connected with the brush head, a

handle slidably and non-rotatably mounted upon the rock shaft, and means movable with the handle to lock the brush head and cover together. v

3. In a device of the character described, a cover, a brushhead to 'turn Within the cover, a rock shaft mounted inthe cover and rigidly connected with the brush head. to turn iti-,4a handle slidably and non-rotatably mounted upon the rock shaft to turn it and a to movelongitudinally thereof, a spring to oppose the rearward movement of the handle upon the rock shaft, and locking means for the brush head and cover attached to the handle to move longitudinally therewith.

4. In a device of the character described, a cover, a brush head mounted to turn within the cover, said coverand brush head having openings adapted to be brought into registration, a handle connected `with the brush head to `turn it and adapted to be shifted longitudinally with relation to the cover, and a. lockin element carried by the handle and adapte to enter said openings when' they are brought into registration.

5. In a device of the character described,

extending longitudinally of the cover and pivotally connected therewith and projecting beyond the cover at one end, a brush head mounted upon the rock shaft to be turned upon its longitudinal axis by said rock shaft, a handle slidably and non-rotatably mounted upon the projecting end of the handle, yielding means to urge the handle longitudinally toward the cover, and means to lock the brush head with the cover, said means includin an element connected with the handle to Ire moved thereby.

In testimony whereof I afix my signature.

CHARLES C. TRESTER.
