"WILLIAM M. ELLING, OF NEI/V YORK, N. Y.

MANUFACTURE OF BACKS AND HANDLES FOR BRUSHES, 800.

SPECIFICATION forming part of Letters Patent No. 426,630, dated April 29, 1890.

Application filed September 8,1885. Serial N0.1'76,062. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM M. WELLING,

. of the city and State of New York, have invented an Improvement in the Manufacture of Backs and Handles for Brushes or Mirrors, of which the following is a specification.

Before my invent-ion brush backs and handles have been made of wood sawed out to shape and carved by hand. In some instances the handles have been of two thicknesses of wood glued together. The manufacture in this manner is costly, and the two pieces of wood when sawed out do not always correspond in size or shape and the edges and backs have to be finished up by hand, thus increasing the cost of manufacture. Brush and mirror backs and handles have also been made of a plastic composition pressed up to shape in dies, but this material is usually too expensive for certain qualities of brushes and hand-mirrors. I make use of dies that are adapted to the twofold duty of cutting .out the wood to shape and pressing the same up into the ornamental form desired, thereby avoiding the sawing out of the brush-block and the ornamentation or shaping of the same by carving,because said dies perform the two operations simultaneously and at one stroke. Furthermore, the wood that I make use of is thicker than the brush-back when finished, in order that the necessary strength may be obtained, and the finished back will not be as thick and clumsy as it would be if it was not compressed and consolidated in the manufacture, and the completed back or block is stronger than it would beif of the same thickness of wood in the ordinary condition.

In the drawings, Figure 1 is a longitudinal section of a brush made according to my in vention. Fig. 2 is a view of the back, and Fig. 3 is a section of the die made use of in cutting out and pressing up the back.

The die a is of steel in the form corresponding to the outline of the brush or mirror handle and back. This die is made with a sharp cutting-edge b all around it, and the surface of such die at the inner side of the cuttingedges is rounding, inclined, or beveled, as at c, and the remainder of the surface between the cutting-edges is either plain or more or less ornamented with designs and figures, as at cl. The die outside the cutting-edge is removed suftieiently to prevent the surplus wood being compressed, thus causing the concentration of the pressure upon the article that is being shaped and pressed and causing the cut to be clean.

In using this die there is a flat plate for the counter, so that when a piece of wood of suitable thickness is placed between the flat counter and the die and said die brought down forcibly upon said wood the same is cut out by the sharp" edge of the die, and simultaneously the edges are rounded by the rounding shape of the die adjacent to the cutting-edge. Furthermore, the wood is consolidated and hardened by the pressure and more or less ornamented, and its surface is made to correspend with the surface of the die.

The brush-block f, into which the bristles are drawn after said block has been perforated, as usual, is cut out by a matched die similar to the die (L, that makes the back portion g, except that the surface should not be ornamented by embossing or figures.

The two pieces f and g are to be glued together after the bristles have been put into the block f, or if the parts f and g are used for a mirror the proper openingis to be made for the reception of the glass.

This mode of cutting out brush or mirror blocks or backs allows the parts to be put together with but little finishing by hand, as the surface is hard and smooth and adapted to being varnished or otherwise completed for the market.

I claim as my invention- 1. The handle and back forbrushes or mir-' W. M. WELLING.
