Application filed September 29', 1921. Serial No. 504,164.

the brush head audits handle so that there shall be both a rigid connection and' one which will permit easy separation of head and handle.v This invention also includes the idea of so connecting the head and handle as to eliminate the'tendency of torsion to cause the breaking of the holding means connectinghead and handle'an'd prevent the rotationof the handle with relation to the head.

My invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawing, and whileI have shown therein, preferred embodiments, I desire the same tobe understood as illustrative only and not as limiting my invention, v

In the drawing attached hereto and forming a part hereof:.- Fig.1 is a side'elevat'ion of a brush head with a fragmentary. showingof the handle to show the shape of the brush head and to illustrate the manner of attaching the two elements.

Fig. 2 is a plan view of the structure shown in Fig. 1.

Fig. 3 is a perspective view of the handle member shown in' Figs. 1 and 2 together with the means for attaching the handle to the brush head or body and preventing the rotation of the parts thereof with respect to the body portion. 7 i

Fig. 4- is a fragmentary showing of the brush head illustrating asimplified con-.

struction for use in brushes in which it is.

while 4 designates a U-shaped fastening member passed through the body and the ends of the handle. As shown in Fig. 3, the handle 2 is U-shaped and is provided in or near its ends with notches 5, while there ends perforations 6, adapted to receive :the ends of the U-shaped fastening, member 4. A notch 7 of any desired shape may be provided in thebrush body for the insertion of a: small implement for the removal of the fastening member 4.

It will be obviousfrom the foregoingthat when the pin 3 is I passed through the body member 1, and the handle member 2 1s mare provided, somewhat removed'from the serted into the perforations in the end of the body member until the notches 5 closely engage said pin, itwill be, almost out of the question-for the parts of the handle'Q to rotate in the openings'ln the body'member because of the close fit of the openings 5 and the pin 3. Alsothe fastening member 4 "fits closely in openings in the body member and in openings 6 in the handle member, .thus also assisting in preventing rotation of these members in relation to the bodyimemher as well as preventing withdrawal of the handle member from-the body member.

In brushes in which it is not necessary to 7 provide against so im'uchftorsional strain the structure can be simplifiedas showirinFig. 4, by omitting the fastening member 4, and its cooperating perforations in brush body and handle and substituting forthe notches 5- corresponding perforations a little removed' from the ends'ofthe handle. .By

then insert-ing'a pin 3, which' closely fits these perforations; rotation .of'the handle parts because ofthe-torsional strain will be prevented, andthe handle will be unable to break the pin. omits the added advantage, to be obtained from the use ofthe member 4, which cooperates with pin 3 in preventing the destructive effects of the torsional strains. It is obvious that, if desired, member 4 may be used in the form illustrated in Fig. 4.

As shown in Figs. 1 and 4, the brush body Of course, this construction The surface defined by the bristle ends ,is

also curved so that the parts are properly arrangedto serve most efficiently in all situations. The central, curved part Wlll serve for cleaning angles while the plane portions will serve for cleaning verticalmwalls or besides the spokes.

the bottom of bath tubs and the like. These parts Will also serve very effectively for the cleaning of various parts of automo il s t will be een f om the foregoing that not only is the connection between the brush handle and head veryeiiicient and effective and easily connected and detached, but the brush head itself; is so shaped that it can be readily used to Wa h in many difficult lo ation the o tuse angle twee the par s f the head having. en found t e th most sa sfa ory one which could e ch sen:

It is, of oursenndcrstood ha the pecific descriptio of stru ture set forth above may be I departed from Without departing from the spirit of my invention as set forth n h s spec fic tion and the appended cla msv Having now described my invention, I c aim a 1. In a construction of the character de scribed, a body having a pair of holes there.- in, a handle comprising a, co-operating pair of arms adapted to be inserted into said h s, Said arms having transverse notches the ends thereof and a pin passing through the body and the notches in the ends of the arms.

2, In a construction of the character described, a body having a pair of holes therein, a handle comprising a co=operating pair of arms adapted to be inserted into said h sai rms having transverse holes nea th n s' holfeof and a fastener passing through the body theho es in the arms.

3.. n a c ns ruction of the character described, a body having a pair of holes there in, a handle comprising a co-0perating pair of arms adapted to be inserted into said holes, said arms having transverse notches in the ends thereof, a pin passing through thebody and hr ugh the notches in the ends of the arms, transverse holes near the ends, of the arms, and a fastener passing through the body and through the holes in the arms to holdthe two together.

4. In a brush, a body having a pair 01 substantially-parallel holes'therein, a handle having a pair of arms extending into said holes and themselvesbeing provided at their ends with a pair of notches and near their ends With a pair of perforations, a pin exending through the body and the notches in the arms to assist in preventing rotation of saidarms insaid body,'and.fastening means extending through the body and the perforations to prevent the separation of said body and arm..

5.. Ina brush, a body having a pair of substantially, parallel, longitudinally extending holes, a U-shaped handle having its arms extending into "said holes, said arms having adjacent their ends holes extending in substantially the same direction transversely of the axes of-the arms,;a nd a U- shaped fastening means extending through the body and the arms to hold the parts in assembled relation and assist in preventing rotation of each arm in its respective hole.

6. In a brush, a body having a pair of substantially parallel, longitudinally extendingholes in one end of said body, a

U-shaped handle having its arms extending .into said holes, said arms having adjacent their ends holes extending in substantially the same direction and transversely to the holes inthe body, and fastening means extending throughthe body and arms to hold the parts in assembled relation and assist in preventing the rotation 01" the arms in their respective sockets.

In witness whereof, I hereunto subscribe my name to this specification.
