UNITED STATES PATENT OFFICE.

H. LOVELESS, OF LAFAYETTE, INDIANA, ASSIGNOR OF ONE-HALF TO CHARLES L. DANIELS, OF TIFFIN, OHIQ.

BRUSH.'

$PECIFIGATION forming part of Letters Patent No. 710,161, dated September 30, 1902. Application filed April 4, 1902. Serial No. 101,348. (No model.)

To all whom it may concern.-

Be it known that I, FRED H. LovELEss, a citizen of the United States, residing at Lafayette, in the county of Tippecanoe and State of Indiana, have invented certain new and useful Improvements in Brushes, of which the following is a specification.

The object of this invention is to provide a sweeping-brush having bunches or tufts comprising a mixture of bristles and vegetable fiber which will be cheaper than an all-bristle brush and owing to the favorable disposition of the bristles with relation to the vegetable fiber substantially as durable.

The object also is to provide a strong and economical means for securing the bunches to the brush-head.

I accomplish the objects of the invention by the mechanism illustrated in the accompany- 2o ing drawings, in which Figure 1 is a view in front elevation and partial vertical section of my improved brush; Fig, 2, an end View of same, and Fig. 3 a diagram showing the manner ofconstructing the 2 5 tufts.

Like characters of reference indicate like parts throughout the several views of the drawings.

1 represents the brush-head, preferably of.

0 wood, having an under flat side, with a series of round holes to receive the bunches. Each of these holes comprises an outer circular opening 2 and an inner concentric open ing 3 of less diameter. The bunches of fiber 5 are wrapped around a short wooden core 4. This core takes into the smaller and deeper opening, while the bunch end is received in the larger and outer opening 2. In making the said bunches I rotate a rod long enough 0 for a number of bunches in a lathe, and after the bunches are formed detach them from the rod as made by sawing off the requisite length of rod. In the formation of a bunch the first operation is to kerf the rod transversely,

as shown at 5, and lay therein the wire 6, with its projecting end bent down toward the adjacent end of the rod. Then the body of the wire is wrapped around the rod and upon the short turned end of the wire. The proper 5o amount of bristles is then fed evenly under the wire upon the rod and the wire is continued around the half completed bunch two or three times toward the end of the rod, and then a layer of vegetable fiber, such as is commonly used for making brushes, is laid upon the bristles and the wire continued around the outside of it two or three times, as shown in Fig. 3. The end of the wire is finally secured by wrapping it around a tack or nail 7, driven through the fiber and bristles into the rod. The wrapping of wire around the rod before the tack is driven therein prevents the splitting of the rod by the tack. After the wire is fastened to the tack the combined layers of bristles and fiber are doubled back upon themselves and pounded to compress them. Then a ring of suitable diameter is forced on overthe shoulder formed by the bent fiber and bristles to hold same in place until inserted in the brush-head, when the ring is removed. After the 'ring is in place the rod is sawed off about a half inch from the shoulder. The head of the bunch thus completed is dipped in a germ and water proofglue and then inserted in one of the double holes in the brush-head, where it is additionally retained by a small nail or brad 8, driven through the side of the brush-head into the rod above the shoulder of the bunch.

My object in tying a layer of bristles on the rod first and then 'a layer of the vegetable fiber on the bristles is to fortify the fiber by the inner core and outer' layer of tough elastic bristles and to stiffen the bunch and cheapen its cost of production by introducin the intermediate layer of fiber.-

0 Having thus fully described my invention,

.what I claim as new, and wish to secure by Letters Patent, is-

1. 'Abrush head having holes to receive the 0 bunches and bunches secured in each of said holes, each bunch comprising a core, a layer of bristles surrounding the core and wired at its middle thereto and a layer of fiber surrounding the bristles and wired thereto after 5 which both fiber and bristle layers are bent back upon themselves to form a bunch wherein said fiber is in an annular body between a center body of bristles and an outside layer of bristles.

2. In a brush, a brush-head havingaseries of holes to receive the bunches and bunches IOO secured in each of said holes said bunches I mately their middles and the fiber and briecomprising a wooden core kerfed transversely, a Wire laid in said kerf with a projecting end bent toward the end of the core and held by Wrapping, the wire over it; a layer of bristles evenly distributed around the core and held thereto by a wrapping of wire; a layer of fiber around the bristles held by a further wrapping of the same wire and a tack driven into the core to which the remaining loose end of the wire is fastened, said wire Wrappings of bristles and fiber being at approxitles being doubled at the wrappings to form a bunch in which an annular layer of fiber is
