RENEWABLE SPOTTING-BRUSH- Filed Oct. 17, 1941 INVENTOR. MAX 6/154 50?.

Z? v BY Patented Dec. 22, 1942 UNITED STATES PATENT OFHQE RENEWABLE SPOTTING BRUSH I Max Ghelber, Denver, 0010.

Application October 17, 1941, Serial No. 415,359

1 Claim.

This invention relates to a brush, more particularly to the type brush used by dry cleaners for removing spots from clothing. Such a brush is known to the trade as at spotting brush.

The principal object of this invention is to provide means in a spotting brush whereby when the bristles at the used extremity become worn they may be replaced by simply rotating the brush element to a new position on the supporting means so as to double the life of the brush.

Other objects of the invention are to provide a spotting brush in which the brush element and the handle are independent of each other so that renewal and replacements can be easily made without discarding the entire brush; and to provide such a brush with efiicient scraper means whereby adhering materials may be scraped from the garment with the same instrument that accomplishes the brushing.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efiiciency. These will become more apparent from the following description.

In the following detailed description of the invention reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. 1 is a perspecive view of the improved spotting brush;

Fig. 2 is a similar view of the removable brush element; and

Fig. 3 is a perspective view of the handle member with the brushing element removed.

The improved brush comprises a frame block In from which a handle H projects. The frame block and handle are preferably formed, from a single piece of wood or other suitable material. A convex brush receiving surface I2 is formed on the lower face of the'frame block terminating adjacent the handle I l in a downwardly projecting shoulder member l3.

The brush element comprises a brush back I 4, preferably formed of non-corrosive metal such as aluminum, having a concave flange I5 extending around its upper edge. The concavity of the flange fits the convexity of the surface l2 and the end of the brush back fits snugly against the shoulder member [3 of the block Ill.

The brush back is held in place against the block by means of an attachment screw I6 which passes through the block l0 into a threaded screw tachment screws 2|, the screw l6 extending through an opening in the blade. The forward extremity of the scraper blade 20 projects beyond the block Ill and curves upwardly therefrom so that when the block is turned over, the edge of this blade will contact the garment being cleaned.

The flange [5 of the brush back is notched at both ends, as shown at 22, t allow passage of the projecting scraper blade 20. The scraper blade and the brush block ID are protected from moisture by means of a flexible rubber sheet 23 secured to the face l2 by means of suitable tacks 24.

In using such a brush only the bristles at the scraper extremity are ordinarily used. These bristles therefore become worn away more rapidly than the remainder of the brush. When such wear occurs with this improved brush, it is only necessary to loosen the screw l6 and turn the entire brush element half way around to bring fresh bristles into play. The screw is then again tightened to lock the brush in place.

It will be noted that the convexity of the surface l2 cooperates with the curve of the brush to prevent movement of the latter. This is assisted by the shoulder member l3 which bears against the inclined rear of the brush back to assist in locking it in place.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claim, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:

A renewable spotting brush comprising: an arcuately curved brush back, the edges of said brush back being outwardly flared toward the concave back thereof; bristles projecting from the convexedly curved front of said brush back; a handle member; a fram block on one extremity of said handle member; a recess in said frame block for receiving said brush back; an outwardly arched back in said recess fitting into and against the inwardly rounded back of said brush; an inclined end wall in said recess positioned to fit against either flared end of said brush back to lock the brush back in place in said recess; a clamp screw extending through said frame block into said recess; and a threaded recess for said clamp screw in the concave back of said brush back said recess being at the exact middle of said opening 11 in the brush back. The brush back back so that either d of sa d ba y b is provided with suitable bristle I8 wired thereto by means of attachment wires I9.

A curved scraper blade 20 is secured against the curved surface l2 by means of suitable at- -placed against the inclined end wall of said recess before said screw is tightened.
