1,1. LALLY. SCRUB BRUSH.

APPLICATION FILED JAN. 2,1918- Patented Feb. 3,1920.

WITNESSES. I I

l object tov provide abrush of the class, which JOHN J. anny; or sYRacUsn, NEW. "roan.

scaunnnn srn Thrall whom itmay concern:

Be it known that I, Jor-rN J. LALLY, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Scrub Brushes, of which the follow'ingis a specification This invention relates to-improvements, 1n scrubbing brushes, and has for=its particular is especially adapted and intended .for

scrubbing walls and like surfaces. A further object is to-provide a simple and con venient handle which is pivotally connected 1 to the back of the common.scrub-brushes,

and may. be detached when a brush-is worn out and applied to a new brush. A further object is to so apply the handle to theback of the brush that when applied to a wall or other vertical surface the brush, acting .under the influence of gravity, readilyassumes the proper position, substantially parallel to the wall, for facilitating the scrubbing or cleaning of the wall. And a. further object is to generally improve and simplify the construction and operation of brush holders.

I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawing, in which Figure 1 is a perspective view; showing a portion of a brick-wall, to which my improved scrubbing device is applied. 7

Fig. 2 is a side elevation, with parts of the brush and handle broken away; showing the'construction and arrangement of the various parts.

It has long been the custom to paint brick and stone walls, so as to protect them and improve their appearance, and in carrying out this work, such walls are invariably scrubbed or otherwise cleansed and nut in condition to receive the paint or other dressing. Ordinarily to clean brick or stone walls, the cleaners dash a quantity of acid, usually muriatic acid, over the surface of the wall, then they dash water over the acid covered surface, after which, the operators, by means of common scrubbing brushes scour and cleanse the walls. Heredoing the scrubbing work. more or less of the acid comlng in contact Specification'of Letters Patent 1 Application filed January 2, 1918. SerialNoJ 209,812.

with the operators hands andalso spatter ingover theirclothes and burning and injuringithe same. ,To'remedy these defects and to prevent the said injuries, I'have dev1sed a1 noveliand simple handle attachment,

which enables the operator to do his work more readily and with greater ease and safety, because he can'keep. at a safe distance from the acid, covered walls while doing the scrubbing work. A detailed description of my invention follows:

In the drawing, 2 represents a scrubbing brush of conventional form, having a substantial back 3, and the usual bristles 4. Scrub-brushes of the class are generally made with wooden backs and in many different forms and sizes, but as a rule they have a greater length than breadth, as shown. My improvement consists of a handle 5, which holder is flattened and fan-shaped. The

handle is preferably held in place by rivets 9, which pass through the handle and holder,as shown in Fig. 2.- The fan-shaped end 8 of the holder is provided with similar spaced hinge-loops 10, which straddle and receive a single loop 11, the latter being an, integral part of a second hinge-member l2,

which is suitably secured to the top-face of the back 3 by screws 13. A pintle or pin 14: is then driven through the loops 10-11 for completing the hinge structure. In applying the member 12 to the back 3 of the brush, the said member is preferably disposed forwardly of the middle of the back 3, as shown, so that when the brush is lifted up bythe handle and brought into contact with a wall, as 15, the brush gravitates to the proper position parallel to the wall. Thereafter, as the handle 5 'is manipulated for moving the brush upwardly and downwardly, overthe wall, the brush retains its.

vertically over the wall-surface, or it may be given a rotary motion, without danger of breaking or injuring the hinge connections. Obviously, a brush equipped with my improved hingeand handle may be used for scrubbing floors and other surfaces, as

may be made of wood, the lower end thereof i a solid elongated back, of a stationary hinge member secured to and extending transversely of theback near one end thereof and provided with a pintle loop, a-inovablehinge member having one end thereof formed with a substantially eylinchical ferrule and its otherend flattened and of substantially the same width as the width of the brush back and extending transversely of said brush back, said flattened end being cut away to form spacedpintle loops of the same sizeas and disposed on opposite sides of the pintle loop of the stationary member and in the same plane therewith, a pintle pin extending through all of said loops, a handlefitted in the ferrule and terminating short of the flattened end of the hinge member; and a rivet extending through the flattened portion of the movable hinge member between V the cut away portionthereof and the end of said handle. 7

2. The combination with a brushhavin'g secure by an elongated back, of a stationary hinge member, secured to and extending transversely of the back near one end thereof and having a transverse pintle 100p lying at one side against the face of the *ba'clz, a handle having its attached end tapered, a movable hinge member having one end thereof provided with a tapered ferrule disposed in longitudinal alinement with and receiving the tapered end of the handle and its other end flattened and extending transversely of the back for substantially the'eiitire width of said back and 7 nating at its ends substantially at the plane of the face of the back of the brush, whereby in one extreme position of swinging movement of the handle the same may extend substantially parallel to said plane.

In testimony whereof I aflix my signature.

JOHN J. LALLY.
