SPECIFICATION forming part of Letters Patent No. 557,923, dated April '7, 1896,

Application filed May 16, 1895. fierlal No. 549,479. (No model.)

To all whom it may concern.-

Be it known that I, HERMAN WEHNER, a citizen of the United States, residing at Detroit, in the county of WVayne and State of Michigan, have invented certain new and useful Improvements in Machines for Making Brushes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention is especially designed for manufacturing the brush described and claimed as my invention in a concurrent application, Serial No. 549,128; and the invention consists in the construction and operative combination, in a single machine, of different mechanical appliances for doing the work in a simple and expeditious manner, all as more fully hereinafter described in connection with the accompanying drawings, in which Figure 1 is a perspective view of the brush as completed by the machine. Fig. 2 is a perspective view of the parts of which the brush-head is composed. Fig. 3 is a perspective view of the machine which forms the subject-matter of this application. Fig. 4: is a plan view thereof with the hinged frame which carries the gate omitted. Fig. 5 is a vertical cross-section substantially on the line main Fig. 4. Fig. 6 is a vertical central longitudinal section on line y y, Fig. 4. Fig. 7 is a vertical cross-section through the bed-plate and rockbars, showing one bar in the act of bending the metal flaps of the brush-head.

A is a suitable base, by means of which the machine can be firmly secured upon a work table or bench. B are two vertical standards secured to opposite sides of the base. 0 is a horizontal bed-plate secured between the standards. D is a groove formed upon the upper edge of the bed-plate.

E are two rock-bars secured upon pivots a between the standards on opposite sides of the bed-plate C.

F are rock arms or fingers formed on the upper sides of the rock-bars.

G are bails by means of which the rockbars are turned upon their pivots.

II is a bail hinged at its free ends at h to the standards.

I are keepers formed on the standards, adapted to maintain the bail H in a vertical plane.

J is a gate vertically slidingly secured upon the upper portion of the bail H.

J are presser-feet formed upon the lower edge of the gate. I

K is a forked hand-lever pivotally secured upon the bail H.

L is a cross-bar in the fork of the lever K. M are toggles pivotally secured upon the cross bar L and having their free ends notched and engaging on top of the gate J. N are links connecting the cross-bar L with the gate. 4

0 indicates spring-guides secured to any suitable part of the machine, such as the bed 0, and extending upwardly and outwardly between the rock-bars on opposite sides of the bed-plate O, and P indicates retainingsprings secured to uprights A on the base, which springs terminate at their inner ends, above the bed-plate, in upwardly and outwardly projecting guides P.

The machine is adapted to make the brush shown in Fig. 1, which is composed of a metallic head R, in which two rows of bristles S S are radially secured, and two bunches of bristles T T are secured in the opposite ends of the head.

For the use of the machine described the head R is made of sheet metal in the gutterlike form shown in Fig. 2, wherein c represents notches cut into the edges of the head.

7 This head B. is just of a length and size to fit between the rock-bars E into the groove of the bed-plate O, and if so introduced the notches o register with the interstices between the rock-arms F. After inserting this head bunches of bristles are placed crosswise the rock-bars into the notches c of the head, and then a wire U, previously prepared and formed with the hooks U at the ends, as shown in Fig. 2, is placed on top of the bristles.

If the finished brush is to have the end bristles T T, a bunch of bristles is placed, before introducing the wire, into each hook U, as shown in Fig. 2. In placing this wire into the machine it will be seen that the function of the spring-arms P is to hold the wire down upon the bristles, while the guides 0, Which are near the ends, hold the bunches of bristles in the hooks U in position.

The machine being thus prepared for operation, the operator raises the bail H into vertical position, firmly interlocking it With the keepers I. By depressing the lever K he forces the gate down firmly upon the Wire until the position of the toggles is such that the gate becomes locked. Then he raises first one bail and then the other bail G. The effect of operating the bails G is to bend over the flaps d, (which intervene between the notches of the head,) and thereby firmly confine the Wire in the head and secure the bristles.

What I claim as my invention is 1. In a brush-machine, the combination with the supporting-base and standards, of the bed-plate adapted to support the head of the brush, the rock-bars pivoted in bearings at opposite sides of the bed -plate having each the projecting arms, and a verticallysliding gate, having presser-feet and supporting means for the gate, substantially as described.

2. In a brush-machine, the combination of the supporting base and standards, the

grooved bed-plate O, the rock-bars E upon opposite sides of the bed-plate each provided With arms F and bail G, the hinged bail II pivoted to the standards and carrying the sliding gate J, the presser-feet J on the gate, the lever K carried by the bail II and its actuating toggle connection for moving the gate J, the presser-springs P, the guides O, and supports for'said springs and guides all arranged and constructed to operate substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
