BRUSH AND THE LIKE.

Application filed August 1o, 1922. serial No. 580,830.

To all whom t may concern:

Be it known that we, LEE SNYDER and CLARENCE SMITTJI,` both citizens of the United States, and both residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvelnents in Brushes and the like, of which the' following is a specification.

, This invention has to do with certain iinprovements in brushes and the like. The invention has reference particularly to improvements in brushes for toilet purposes, but it will appear from" an examination of the drawing that brushes embodying the features oftheinvention are no-t limited to this or any other particular class of servlce.

One of the objects of the invention is to provide a brush having the bristles removably mounted on a handle section in such a manner that the same handle section can be used with different forms and characters of bristle sections. For example, the handle section can be used with a bristle section having relativelysoft pliable bristles or with a bristle section having relatively stiff bristles. Thus the usefulness of the handle portionwill be considerably enlarged, and it will be possible to use the same handle for widely different classes of service. This will also make it possible to standardize the construction of the handle and other parts of the brush.

Another feature of the invention relates to a construction of. brush which is so arranged that a current or stream of water may be continuously delivered into or against the bristles, so that when the brush isiused for toilet purposes the advantages ofthisv arrangement may be secured. In this connection, a further object is to provide a very siinpleforin of construction and one which will readily lend itself to satisfactory use with a simple arrangement of handle. l

Other objects and uses of the invention will appear from a detailed description of the same` which consists in the features of construction and combinations of parts hereinafter described and claimed.

Referring to the drawing:

Figure l shows a longitudinal section through a handle unit, the brush unit being located therein and secured thereto;

Fig. 2 shows an enlarged fragmentary dethe head 6.

tail section of the upper portion of the handle unit showing in'detail the construc- 5 havingat its upper end a head portion G. As shown in Fig. L this head portion is preferably of somewhat oval section, being broader in one direction than in the other. Furthermore, the hand grip is preferably bulged out in its central portion 7 so as to provide a convenient and substantial element which may `be readily grasped and firmly held. Y

The head portion 6 is provided with an inwardly reaching recess 8. Ordinarily this recess extends the entire width of the head portion G and is formed by the upstanding ears V9 and 10 as shown in detail in Fig. 2. Reaching downwardly' from the floor of the recess 8 are the sockets 11 and l2.

The bristle unit `13 ordinarily comprises a pair of wires 14 twisted` together, the bristles 15 having their inner ends twisted in between the wires, so that the bristles project therefrom in a series of bundles or pencils, as clearly showniin Fig. 1.

This bristle unit is preferably` bent into a VU-shaped or oval form as shown in Fig. 1, so that the ends 16 and 17 of the wire are brought relatively close together. These ends are relatively straight and adapted to set straight into the sockets 11 and 12 of This co-operation is clearly illustrated in Fig. 1.

Thev opposing walls 18 and` 19 of the -recess 8 preferably flare outwardly from each other as shown in Fig. 2, and it is preferred that the end portions of the wires of the bristle unit should turn over at an angle after leaving the sockets 11 and 12 so as to lie squarely against the walls 18 and 19. By this arrangement, the wires also leave the head 6 in such a direction that they proceed naturally upwards and away from each other into the oval form of the bristle unit.

A wedge block 20 is provided which sets down into the recess 8 so as to close the same and retain the end portions of the wire squarely in place. This wedge block has its end portions provided with sockets 21 and 22 which co-operate with the sockets 18 and 19 respectively. Consequently, when the wedge block is forced down with respect to the head 6, the ends of the wires 16 and 17 being in place, said ends are squarely locked in positionand cannot be withdrawn until the block 20 is released. This retaining action is further enhanced by the fact that the walls 18 and 19 of the recess 8 flare outwardly at an angle, whereas the sockets 11 and 12 are parallel to each other.

Any suitable means maybe provided for retaining the block 2O in place, but in the construction illustrated we provide a nut 23 which is threaded onto a stem, which stem extends upwardly from the handle unit.

The particular brush construction illustrated in the drawing is provided with means for spraying the bristle unit with water. This means includes a pipe 24 which reaches upwardly from the handle unit and has its upper end 25 sealed. The lower portion of the pipe 2li is threaded as shown in Fig. 1, and threads into a socket 26 in the head G. This socket in turn communicates with a bore 27 running down through the handle 7, so that a hose 28, slipped onto the lower end 29 of the handle may deliver water up through the bore of the handle and through the pipe 2l.

Said pipe 2 is provided with a series of side perfor-ations 30 through which the water is delivered in the form of a spray at both sides against the bristles of the bristle unit.

The pipe 24 provides a convenient element on which to thread the nut 28. For this purpose the lower portion of the pipe is threaded a suitable distance upwardly from the head 6, as shown in Fig. 1, so that the nut 23 can be threaded up along the pipe a sutlicient distance to completely release the wedge block 20. This wedge block in turn is provided with a central bore 31 through which the pipe 24 extends, but which bore does not thread onto the pipe but is sufiiciently large to slide freely on the pipe.

lVhile we have herein shown and described only a single embodiment of the features of our present invention, still We do not limit ourselves to the same except as we may do so in the claims.

lVe claim:

1. As a new article of manufacture a brush comprising in combination a handle unit having a suitable hand grip, a head at one end thereof, there being a longitudinally extending bore, through the hand grip and head, a hose connection at the other end in communication with said bore, there vbeing' a central recess reaching inwardly into the head and having a floor lying at right angles to the axis of the handle, there being a socket reaching into the head at each end of said floor and at right angles thereto, a spray tube threaded onto the head and extending longitudinally therefrom and in communication with the bore of the handle unit and provided with a series of side spray orifices, and a U-shaped twistedvbristle holder of generally oval shape and having the ends of its wires brought relatively close together and into parallelism and adapted to reach directly into the floor sockets, a wedge block adapted to seat into the recess of the handle unit and against the end portions of the wires of the bristle unit, and means for clamping the wedge block into said recess comprising a nut threaded onto the spray nozzle and against the wedge block, substantially as described. 2. As a new article of manufacture a brush comprising in combination a handle unit having a suitable hand grip and a head at one end, there being a central elongated recess reaching inwardly into the head and having a floor at right angles to to the axis of the handle, there being a socket reaching into the head at each end of said floor and at right angles thereto, and a U-shaped bristle holder having its ends brought relatively close together and adapted to reach directly into the floor sockets, a wedge block adapted to seat into the recess of the handle unit and against the end portions of the wires of the bristle unit, and means for clamping the wedge bloch into said recess, substantially as described.
