SPECIFICATION forming part of Letters Patent No. 570,604, dated November 3, 1896. Application filed February 3, 1896. Serial No. 577,943. (No model.)

To all whom, it may concern/f Be it known that I, WILLIAM'MQRRISON, a citizen of the United States, residing at Lansingburg, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Brush-Making Apparatus, of which the following is a specification.

The invention relates to such improve-' ments; and it consists of the novel construc tion and combination of parts hereinafter described and subsequently claimed.

Reference maybe had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a top plan view of my improved apparatus. Fig. 2 is aview in side elevation of the same. Fig. 3 is a vertical cross-section of the same, taken on the broken line 3 3 in Fig. 1. Fig. 4 is a vertical cross-section of the same on'the line 4 4 in Fig. 1. Fig. 5 is a plan view of one side of the bristle-plate. Fig. 6 is a plan view of the opposite side of the bristle-plate. Fig. 7 is a view in cross-section ofthe bristle-plate and bristlesin the operation of forming the brushpad. The principal object of my invention is to provide an efficient means for rapidly insert-- ing short lengths of bristle in a recessed or apertured plate in the operation of making brushes by molding a pad of composition around the ends of the knots or bunches of Y bristles.

My invention relates particularly to the method of inserting or feeding the bristles into the bristle recesses or apertures in the bristle receiving'and supporting plate, as well as to the method of forming the brush-pad,

around the ends of the bristles so supported.

Referring to the drawings, A is a plate having a plurality of apertures formed therethrough, adapted to receive and support the several knots or bunches of bristles A to be embodied in a molded brush, which apertures are preferably tapered from one side of the plate to the other. The plate is preferably made of metal and provided on one side with a molding-surface A in which are the smaller end openings of the bristle-recesses.

B is a hopper adapted to contain a supply of bristles, and B a vertical slideway-sup- 5 5 port on which the hopper is mounted by means of the frame B free to slide longitudinally on the support. Reciprocating movements can be imparted to the hopper by means of the cam B mounted u on and ro- 6o The cam is engageable with the under side of the frame B which may be provided with a pad B of leather or rawhide, to resist the wearing effect of the cam. The hopper is provided with a reticulated bottom comprissieves B In the operation of filling the plate with bristles the plate is placed upon a support or carriage D, with its molding-surface on the under side and supported a short distance above the floor of the carriage by means of the ring D, which surrounds said moldingsurface. The carriage is then placed beneath the hopper, the flaring ends of the bristle-apertures in the plate being uppermost, and a supply of bristles having been inserted in the hopper the same is rapidly reciprocated by means of the cam mechanism above described. The agitation thus imparted to the bristles in the hopper causes them to assume various positions therein, in some of which positions the ends of the bristles enter the meshed openings in the hopper-bottom and guide the bristles therethrough in approximately vertical lines. through the hopper-bottom by agitation enter the flaring mouths of the bristle-apertures in the plate A and are guided by the converging walls of such apertures through the contracted end openings to project from the 5 molding-surface A into the space A between such surface and the carriage. As the operation of the hopper is continued the bristleapertures in the plate A are gradually filled,

the apertures until their progress is arrested by engagement with the floor of the carriage or an interposed plate D When the bristle-plate is properly filled, the carriage is taken from beneath the hopper and the surplus of bristles removed from the uppermost The filled plate can then be removed from the carriage by superposing thereupon a plate D and inverting the bristle-plate and plates D and D together, after which the plate D can be removed to expose the molding-surface of the bristle-plate and the ends of the bristles projecting uniformly therefrom in proper position for the application of the plastic compo.- sition in the process of forming a brush-pad.

The brushpad may be formed in any kn own 3 known form of reticulated or apertured bottom adapted to separate the bristles and inl duce an endWi-se movement of the same toj ward the subjacent.bristle-plate.

manner. I have ascertained, however, that it is not desirable to subject the plastic composition to= any considerable pressure in theoperation of forming the brush-pad around the projecting ends of the bristles, for the reason that the. bristles. are not supported or other capilliform brush material.

throughout their length, but; only near or at the molding-surface of the bristle-plate, and their ends: are consequently comparatively free to move in =opposite directions. It is. therefore apparent thatvariations in the lateral pressure exerted upon the projecting ends of the bristleswould tend to causethem to change their position in the apertures, which would render the product unsymmetrical and unattractive. For this, among other reasons, I prefertoform. the-brush-pad in the manner hereinafter described.

The bristle-plate having its tapered apertures filled with bristles projecting from the molding-surface A as. above set f0rth,is;pr;ovided with a removable flange or ring-,whieh may be the ring D used in the operation of filling the plate, and which. surrounds the molcling surface and the space above the sameinto-which the ends of the bristles project'.

I employ for the brush-pad a. fusible com.- position whichl; reduce by-heat to afluid'stat-e, in which condition it is. poured upon the molding-surfiaceof the bristle-p1atear0undthe ends of thebristles, the inclosing ring 1;) preventing theescapeof the-molten material. After a sufficient quantity of the moltenma teria-l has been applied to the bristlB-Plate and distributed properly around, the ends. ot the bristles. it is permitted to -harden. by cooling, and forms, when hard, a. supporting-pad P for the bristles. The removal of the pad from the bristle-plate will withdraw the bristles from said plate, and the connected pad and bristles constitute a brush suitable for many purposes.

The brush may be provided with an ornadurum mental back and handle in any known manner.

The composition for making a pad in this manner may be any known material which can be reduced by heat to a fluid state and will harden upon cooling.

The bristle-receiving plate above described,

, having tapered bristle-apertures, can be used independently of the bristle-feeding hopper 1 and the bristles inserted in the tapered apertures by hand.

The hopper may be provided with any The apparatus above described is adapted to bevused for feeding bristles, brush fiber,

The springs S, as well as gravity, tend to maintain the hopper in its lowermost position, acting in opposition to the cam in producing the reciprocating movements of the hopper.

It is characteristic of my invention that the bristle-receiving plate is supported ina fixed position relatively to the hopper while the hopper is reciprocated toward and from the plate.
