UNITED STATES GEORGE W. STEIN, OF LOS ANGELES, CALIFORNIA.

COMBINATION BRUSH.

Application filed April 17, 1924. Serial No. 707,083.

To all whom it may concern:

Be it known that I GEORGE V. STEIN, a citizen of the United states, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Combination Brushes, of which the following is a specification.

My invention relates to combination brushes and has for its principal object, the provision of a relatively simple, strong and durable and convenient cleaning implement that includes a brush having bristles of resilient metal and a brush having relatively soft, flexible bristles of fibre, hair or the like, and which brush is primarily designed as a readily handled and convenient implement for cleaning and brushing the surfaces of meat cutting blocks and tables.

A further object of my invention is to mount the brush having the relatively light and flexible bristles so that it will slide freely upon the back of the brush having the heavier bristles of metal, thus providing a combination structure that may be conveniently handled during the different brushing operations.

\Vith the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully de scribed and claimed and illustrated in the accompanying drawings in which Fig. 1 is a plan View of the combination brush with the brush having the lighter flexible bristles shifted into its out of service position.

Fig. 2 is an elevational view of the com bination brush.

Fig. 3 is an enlarged cross section taken on the line 3-3 of Fig. 1.

Fig. 4 is an end view with the brush having the lighter flexible bristles shifted into position for use.

Fig. 5 is a plan view of the modified form of the combination brush.

Fig. 6 is an enlarged cross section of the modified form of my invention and showing the brush having the lighter flexible bristles shifted into position for use.

Fig. 7 is a detail elevational view of a modification of my combination brush.

Fig. 8 is a perspective View of a strap that is secured to the back of the brush having the wire bristles.

Fig. 9 is a perspective view of the strap that is secured to the back of the brush having the soft bristles.

Fig. 10 is a perspective view of a metal sheathing member that is secured to one of the brush backs in the modified form of the combination brush.

Referring by numerals to the accompanying drawings. and particularly to the construction illustrated in Figs. 1 to 4 inclusive, 1O designates a brush back, preferably wood, from one of the wider faces of which projects a field of bristles 11, of resilient metal. These bristles may be formed from narrow strips or hands of resilient sheet metal as illustrated, or they may be formed from wire of suitable weight.

Arranged transversely on the back or upper face of the brush body 10 and spaced apart therefrom are metal straps 12, the end portions thereof being bent at right angles so as to lie against the side edges of the body 10 and being secured thereto by means of small nails or screws 13.

A relatively narrow brush back 14 is disposed lengthwise on brush back 10, and projecting outward from one of the side faces of said back 14 is a field of relatively soft flexiblev bristles 15 of fibre, hair or broom straw. Thus the bristles 15 on back 14 are disposed substantially at right angles to the metal bristles 11 on back 10.

Secured to the under face of brush back 14 is a longitudinally disposed metal strap 16 that is recessed or indented as designated by 17 for the accommodation of straps 12, the latter lying between the recessed portions of said strap 16 and the back 14.

The parts just described are fitted together so that brush back 14 will slide freely, transversely of brush back 10 and to guide the back 14 during such sliding movement and prevent binding between the parts, one end of strap 16 is bent downward to form a lip or finger 18 that bears against the corresponding end of back 10 during relative movement between the brush backs.

When the brush having the metal bristles is being used to brush and scrape the surface of a meat block or the like, brush back 14 is shifted to one side on top of back 10 so that said back 14 and the bristles carried thereby, directly overlie said back 10 as illustrated in Figs. 1 and 3. hen it is desired to use the brush having the lighter flexible bristles 15. back 14 is moved across back 10 into position at the side thereof where said bristles project wholly beyond the back 10 as illustrated in Fig at.

In the modification illustrated in Figs. 5, 6 and 10, the back 14 that carries the field of relatively soft flexible bristles is partially covered with a sheathing 19 of suitable sheet metal, and in order to receive the transverse straps 12 on the back 10 so as to slidably connect the two backs, the under or inner portion of the sheathing is recessed as designated by 20 and slotted as designated by 21.

At the end of the sheathing 19, a portion is extended downward to form a guiding lip or finger 22 that bears against the end of back 10 during relative movement between the backs. In Fig. 7, the strap 16 is made straight, without the recesses 17 and the back 14: is provided with shallow transversely disposed recesses such as 23 for the accommodation of the straps 12.

Thus it will be seen that I have provided a relatively simple, strong and durable combination brush that may be conveniently handled and effectively used for, cleaning the surfaces of butchers blocks, meat cutting tables and the like and in which one bristlecarrying back is mounted so as to slide into and out of position for use, upon the other bristle-carrying back,

Obviously minor changes in the size, form and construction of the various parts of my improved combination brush may be made and substitutedfor those herein described without departing from the spirit of the inventiom the scope of which is set forth in the appended claims.

I claim as my invention:

1. The combination, with a pair of straps arm nged parallel witheaeh other and having downwardly-turned ends that are adapted to be secured to a brush back, of a strap positioned beneath the parallel straps and having depressed portions that are adapted to receive said parallel straps, which second mentioned strap is adapted to "be secured to a brush back.

2. The combination, with a pair of straps arranged parallel with each other and having downwardlyeturned ends that are adapted to be secured to a brush back, of a strap positioned beneath the parallel straps and having depressed portions that are adapted to receive said parallel straps, which second mentioned strap is adapted to be secured to a brush back, and one end of the strap that is positioned beneath the parallel straps having one end bent downwardly to form a brush back guiding finger.

3. The combination of' a back member, a pair of guide straps having downturned ends secured to the sides of said back member, with the straps arranged in parallel re} lation andslightly spaced above said back member, a strap slidably positioned beneath the guide straps and having depressed portions receiving said guide straps and a brush back secured to the slidable strap.

In testimony whereof I afiix my signature.

GEORGE STEIN.
