FREDERICK J. A. KAME. OF BOSTON, MASSACHUSETTS.
BRUSH HEAD.
Application filed April 19, 1920.
To all whom it may concern:
Be it known that I. Fnnnnnrcn J. A. KAMP, a citizen of the United States. residing at Boston. in the county of Suffolk and State of Massachusetts. have invented new and useful Brush Heads.
My invention relates to in'iproveinents in brush heads. Its principal object is to pro vide for the construction of brushes of large size and light weight. having one or more longitudinal rows of bristles surrounded by a circuit of bristles. My invention is not limited, however, to brushes so made but it is adapted to the manufacture of. brushes with one or more rows of bristles without a surrounding circuit of bristles, and to the manufacture of brushes with a circuit of bristles only.
I attain these objects by the use of brush head made preferably of sheet metal in the form and construction shown in the accompanying drawings, in which similar letters refer to similar parts through the several views. The form shown is designed for an. oblong brush. Figure 1 is a plan of a brush head as assembled and before the brush bristles are inserted; Figure 2 is a side elevation; Figure 3 is an end elevation; Figure 41. is an inner transverse brace; Figure 5 is a perspective of a brush head, in-
verted, as it appears before the brush bristles are inserted; Figure 6 is a longitudinal sec-v tion of a brush head with the brush bristles inserted. taken along a line deflected midway of the brush, the left half of the section taken along a slot B and the right half of the section taken along plate C; Figure 7 is a cross section through the brush head taken at right angles to Figure 6 on a line through one of the inner transverse braces D. In constructing my brush head a strip of sheet metal is bent into a frame shown as E. The inner transverse braces D are formed with ears shaped on the ends thereof. These ears are inserted into corresponding holes in the sides of the frame E and the protruding ends of the ears are upset. At this stage of the construction of the brush head the structure is a light frame rigidly braced by the inner transverse braces. The teeth of the inner transverse braces project upwardly so that the ends of the teeth are substantially in a plane with the upper edges of the frame E. The upwardly projecting teeth of the inner transverse braces D are integral with the inner transverse braces.
Serial No. 375,129.
(7 is a sheet metal plate of smaller dimensions than the interior dimensions of the frame E. and having several longitudinal slots B. This plate C. is the upper surface of the brush head. The upwardly projecting teeth of the inner transverse braces D are inserted into corresponding holes in the plate C and the protruding ends of the teeth are upset. The plate C is so assembled with reference to the frame E. that the plate C. is substantially on a plane with the upper edges of the frame E. and a space or outer circuitous slot adapted to receive brush bris tles is left between the outer sides and ends of the plate 0 and the inner sides and ends of the frame E. The cut away portions of the inner transverse braces D coincide with the slots B in the plate G and the outer circuitous slot A.
After the brush head is assembled above described, brush bristles are inserted by hand from the upper surface of the plate C through the slots B and through the outer circuitous slot A. The butt ends of tne bristles protrude through the slots B and the outer circuitous slot A sufficiently far below the plate C to just clear the upper edges of the inner transverse braces T). The assembled brush head with its inserted brush bristles is-then inverted and melted rubber, pitch or other melted cementing material is poured into the brush head sufiiciently deep to cover the stub ends of the brush bristles where they protrude through the plate C. The brush head is only partially filled with cementing materiah leaving a socket for the insertion of a handle. The setting of the cementing material holds the brush bristles in place. The socket for the insertion of a handle is the space between the bottom of the cementing material and the bottom plane of the frame E. The frame E. thus serves as a container for the cementing material and as a casing to fitover a handle.
My brush head is designed to be fastened to a wooden handle. This is done by mak ing the top of the handle of the same dimensions as the interior of the frame E. The handle is inserted into the frame E as far as the level of the cementing material. The brush head is secured to the handle by driving nails through the sides of the frame E.
into the wooden handle.
I am aware that it is not new to construct a brush comprising a head having a series of longitudinal grooves adapted to contain ill) rows of bristles, also that it is not new to construct a brush having a row of bristles surrounding said longitudinal rows of bristies, and such I do not broadly claim.
My invention is differentiated therefrom in that I avoid the use of any weighty or bulky material in which grooves are cut to contain the bristles, and I obtain in my brush head a construction of great strength and rigidity While having the benefit of light Weight; and I obtain acontinuous outer circuit of bristles Without the use of any Wedges or clamping devices to secure the bristles in place.
I claim:
In a brush head, a plate provided With longitudinal slots, a frame surrounding said FREDERICK J. A. KAMP.
