BRUSH.

SPECIFICATION forming part of Letters Patent NO. 479,082, dated July 19, 1892. Application filed October 31, 1891- Serial No. 410,431. (No model.)

' To all whom it may concern.-

Be it known that I, SAMUEL P. STORRS, a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Brushes, of which the following is aspecification.

My invention relates to an improved toothbrush utilizing aluminum as a frame.

The object of my invention is to construct a brush that shall be durable, strong, attractive, and tasteless, having an aluminum handle or frame, in which frame bristles may be held in the novel manner hereinafter described.

I illustrate my invention by the accompanying drawings, in which Figure 1 is a back View of my improved tooth-brush. Fig. 2 is an enlarged detail view of a part of the same as seen in the same position, but with the capping-piece removed. Fig. 3 is a cross-section of Fig.2 on the line 1 1, showing the bristles in place and the manner in which they are held. Fig. 4 is a plan view of the capping-piece G. Fig. 5 is a side elevation of one of the bristle-retainin g wires. Fig. 6 is a modified slightly-smaller view of the lower side of the tooth-brush, showing the recess, the handle proper being partly broken away. Fig. 7 is a plan view of the grooved side of the perforated cap used in the modification. Fig. 8 is a cross-section on line 2 2, Fig. 9, showing the method of'retaining thecap in the frame. Fig. 9 is a longitudinal section of the modification on the line 3 3, Fig. 8.

Similar letters refer to similar parts in all views.

A represents a tooth-brush handle or back made of aluminum because of its lightness, strength, ta'stelessness, and inability to tarnish. Into the back of this frame A, I cut the recess shown in Figs. 2 and 3. Through the remaining portion of the back, within this recess, I make the lines of perforations B B. Along these perforations on the same side as the recess are made longitudinal grooves D D. In each of these grooves I rests a Wire E, Fig. 5. The bristles F extend up through the perforations, around the wire, and down out of perforations in the manner shown in Fig.

3. A cap G, Fig. at, of the same configuration as the face of the recess in the back of the frame and made of aluminum, is then pressed into the recess and preferably stamped sufficiently hard to cause the edges of the cap to spread under the slightly-undercut edge of the recess, which is preferably at the same time pressed in or down, thereby securely retaining said cap in the brush-frame. By burnishing or rubbing down the edges of the recess the line of demarcation between the frame proper'and the cap G is entirely obliterated, thereby makinga perfect finish to the brushframe. It will be noticed that when the cap G has been inserted and the edges of the recess burnished down upon it in the manner described there can be no place whatever for the water to enter where the bristles are supported in the handle, excepting through the holes from which the bristles protrude.

It is obvious that by an interchange of parts the cap may carry the bristles and be inserted underneath the handle in the way illustrated by Figs. 6, 7, 8, and 9, in which the grooves D D are shown as preferably made in the back of the cap G, Fig. 7,.in which grooves the bristle-retaining wires E, Fig. 9, rest. In this case the back of the recess in the handle A is preferably smooth. (See Fig. 6.) The bristles F run around the wires at the back of the cap and out through the holes B in the cap G, (see Figs. 8 and 9,) said cap being held in precisely the same manner as above referred to by the overlapping or undercut edges of the frame.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is-

In a brush, the combination of an aluminum back provided with an undercut recess adapted to receive the cap, the brush-tufts and means for securing them in their perforations, and the cap secured in the recess by pressure, substantially as described.

Signed at New Britain,in the county of Hartford and State of Connecticut, this 28th day of October, A. D. 1891.
