CLEANING IMPLEMENT;

Application filed February 28, 1923. Serial No. 621,852.

To all whom, it may concern.

. Be it known that 1, JOHN M. BOWEN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented a new and useful Cleaning Implement, of which the following is a specification.

One object of the invention is to provide a cleaning implement which enables both the inside and outside surfaces of windows to be cleaned in an easy and efiicient manner. Another object is to provide a cleaning implement well adapted to be cheaply made on a quantity production basis and which may be easily assembled and taken apart without the use of tools and which may be packed into a small space. A. still further object is to provide an implement in which thecleaning means are of simple design, and'may be easily and rigidly clamped in their, operating position so that the bending thrusts due to the cleaning operation.

will not move them out of their proper operating position. Further objects will appear upon description of the preferred embodiment of my invention which is illustrated in the accompanying drawings wherein, Figure 1 is a side elevation, Figure 2 is a detail view of the bracket and means for securing the brush supporting bar and F igure 3 is a detail View of the brush supporting bar. Figure 4 is a view of the socket broken away.

The handle 1, preferably made of wood or a light metal, is provided at its upper end with a threaded portion 2 for engaging the internal threads 3 of bracket member 4. The bracket is provided with an extension 5 having a flat top surface 6 inclined to the axis of the handle at an angle of substantially 45. A hole 7 is provided in the bracket to engage aretaining screw and adjacent this is a smaller hole in which a pin 8 is rigidly secured, the top of the pin projecting beyond the flat top of the bracket. (See Fig. 2.)

The brush holding part or bar 9 consists of a flat piece, preferably formed of light metal, formed with prongs 10 and 11 two at each end each of said prongs having a hole 12 countersunk therein. On the center line of bar 9 a hole 14 is made the same size as hole 7 of the bracket and spaced equidistant from this are two holes 15 slightly larger than pin 8. A. suitable brush 16 having said brush being tapped for two thumb screws 18 whose conical points 19 engage the countersunk holes 12 in the prongs of the bar. It is easily see that the brus m y be readily and'firmly attached to its support by the means thus provided. A squeegee 20 has two openings26 for receiving two prongs of the bar and is tapped for two thumb screws 21 these having conical points engaging the countersunk holes 12. Squeegee 20 is provided in any approved manher with rubber or felt strips 22.

A standard type of thumb screw 23 is provided for attaching the brush bar to bracket 5 the screw passing thru holes 7 and 14 and, pin 8 being in register witlrone of the small holes 15, upon tightening nut 24 the brush bar is rigidly clamped to the bracket. It will further be noticed that the engagement of pin 8 and slot 15 serve to take up all torsion or side thrust and effectnally prevent rotation of the brush bar on the bracket.

To assemble the cleaning implement the placed on the right of Figure 1 so that the' brush is above the squeegee. In such positlon the brush may be wet with water, gasoline or, other cleaning filllCl and by moving the handle up and down outside a window while keeping the bristles against the glass, the latter will be thoroly cleaned. Figure 1 shows that the angular relations are such that a window may be readily cleaned without exposing most of the body out-side the window. The hands alone outside are sufii-f cient to move and guide the brush. After removing thed'irt, thumb nut 24 is loosened and brush bar 9 revolved about screw 23 as a pivot until slot 15 registers with pin 8 I when upon again tightening nut 24, the bar will be firmly secured with the squeegee in The brush is next at-' its upper, operating position. Upon now moving the handle down while holding the rubber in contact with the glass, the latter will be wiped clean. It is apparent that the implement may be used for cleaning and polishing walls, mirrors, the panels of auto bodies and other surfaces.

V hat I claim and desire to secure by Letters Patent is:

1. A device of the kind described comprising a handlea socket for one end of the handle, said socket being-provided with a lug extending at an angle to the handle a rigid bar having two prongs at each end, and provided with an opening therethrough intermediate the ends thereof, means connected with said lug and extending through the opening in said bar, means engageable with the last named means to clamp said bar and lug together in selected positions, and cleaning means attached to each pi'ir of said prongs.

2. A device of the class described comprising a socket member adapted to be secured to a handle, said socket being provided with a lug extending at an angle to the handle, a rigid bar having two prongs at each end and provided with an opening therethrough, a bolt connected with said lug extending through the opening in said bar, a nut engaging said bolt to clamp said bar and lug together in selected positions,

and cleaning means attached to each pair 01" said prongs.
