BRUSH AND MOUNTING THEREFOR.

Application filed November 2, 1921. Serial No. 512,387.

To all whom it may concern:

Be it known that I, FERD H. MEYER, a citizen of the United States of America, and a resident of Oakland, county of Alameda, and State of California, have invented a new and useful Brush and Mounting Therefor, of which the following is a specification.

My invention relates to brushes and brush mountings.

One of the objects of the invention is the provision of improvedmeans for mounting brushes, especially brushes used in street sweeping machines, so that the brushes are readily replaceable when worn. Another object of the invention is the provision of an improved brush.

My invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of my invention. It is to be understood that I do not limit myself to the showing made by the said description, as I may adopt variant forms of my invention within the scope of the claims.

In the drawings, Fig. 1 is a side elevation of a portion of a chain on which my brush is mounted. Fig. 2 is a plan view of the same. Fig. 3 is a perspective view of the brush separated from the chain.

In general terms the device of my invention comprises a brush formed by folding flexible elements and assembling the folded elements over a core within a U- form retaining plate. The length of the retaining plate is governed by the use to which the brush is to be put, and the flexible.

elements are assembled in the entire length of the retaining plate so that the brush proper is of the same width as the retaining plate is long. Suitable means are also provided for securing the brush in a carrier mechanism which in the present instance comprises twin chains. The mounting is such that the brush when worn may be readily taken out and a new one inserted.

More particularly my device comprises a U-form retaining plate 2 made by folding longitudinally a piece of sheet metal of suitable gauge so that the longitudinal edges are substantially parallel and spaced apart a distance less than the span of the plate at the bend or fold. Lying within the retaining plate longitudinally is a core 3 of the same length as the plate and folded plate.

about the core and within the retaining plate are the flexible elements 4 made of fiber, bristles or wire and which constitute the brush proper. within the retaining plate, a few of the flexible elements are doubled and the loops so formed threaded over the core and pushed down into the recess within the retaining Flexible elements are folded and inserted in the retaining plate in the manner described until the entirelength of the plate is filled when the edges at the ends are bent over by means of a hammer to form retaining lips 5. Nails 6 are then driven thru and clinched to firmly bind the edges of the plates upon the flexible elements. The method of manufacture just described is particularly adaptable for heavy fibers, which After placing the core in small numbers may readily be bent and assembled, but which in heavy bundles Ofi'er hi h resistance to folding.

llleans are provided for mounting the brush so that it may be used in a sweeping machine. mounting means comprises twin chains across which the brushes are fixed at suitable intervals. Each of the twin chains consists of standard chains on which at intervals, say every six links, are fixed U- form socket plates 7 into which the retaining plates 2 of the brush may be inserted, by movement of the brush longitudinally into the end of the socket plates. After-the brush has been seated in the socket plate it may be held therein by a cotter pin 8 passed thru alined apertures in the socket plate and retaining plate. When the brush is worn, removal of the cotter pin permits the worn brush to be withdrawn and replaced by a new one. Each socket plate extends across the spaced twin chains and adjacent its ends is secured to the chains by means of side pieces 9 formed like the side links 11 of the chain but having arms 12 between which the socket plate is secured at right ahglespreferably by welding. The side pieces 9 thus formed at each end of the socket plate a yoke adapted to straddle the chain. and to be secured thereto by pins 13 substituted for the shorter pivot pins of the standard chain. Of course, if desired, the side links of the chain below each socket plate may be dispensed With,

the yoke sides taking their places and being In the instant application the connected by pivot pins of suitable length. In this case the yoke sides become in efiect links in the chain.

It is obvious, without special illustration and description, that the yoke formed by the side plates connected by the socket plates could if desired be mounted on twin disks instead of twin chains, or the socket plate secured directly to the peripheries of such disks. It is also obvious that a brush made in accordance with my invention may be mounted either alone or in combination with others, in any other holder which may be suitable for applying the brush tothe surface to be swept.

I claim:

1. A brush comprising a U-form bundle of flexible elements, a U-form retaining plate overlying the bend of said bundle, a holding means comprising a U-form socket plate in which said retaining plate is laterally engageable, and means for mounting the socket plate.

2. A brush comprising a U-form bundle of flexible elements, a U-form retaining plate overlying the bend of said bundle, a holding means comprising a U-form socket plate in which said retaining plate is laterally engageable, and spaced twin chains on which said socket plate is mounted.

3. A brush comprising a core, a bundle of flexible elements doubled about said core, a retaining plate doubled about said flexible elements and having its longitudinal edges spaced apart a distance less than its spa-n at the bend, a socket plate having a form complementary to said retaining plate, and spaced twin chains on which said socket plate is mounted.

4:. A brush comprising a U-form bundle of flexible elements, a U-form retaining plate overlying the bend of said bundle, a holding means comprising a U-form socket plate in which said retaining plate is laterally engageable, and spaced twin chains including lin {S to which said. socket plate is secured.

In testimony whereof, I have hereunto set my .hand.

FERD H. MEYER.
