$PECIPICATION forming part of Letters Patent No. 366,790, dated July 19, 1887.

Application filed December 6, 1886. Serial No. 220,807. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES ORTI-IER, a citi- Zen of the United States, residing at Goshen, in the county of Elkhart and State of Indiana, haveinvented certain new and useful Improvements in Brushes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a perspective view of my invention; Fig. 2, a sectional elevation thereof, and Fig. 3 detail views in perspective of the confining-plate and rubber ring which acts as the spring for the ball of the handle to the brush.

The present invention has relation to that class of brush-headsin which the handle is connected thereto by a ball-andsoeket joint and a spiral spring employed, which bears against the ball to retain the handle in position when adjusted to the required angle with relation to the brush. The difficulty experienced in the use of the wire spring was the fact that after use for a time each spring was not of itself sufficient to hold the handle of the brush head in its adjusted position, for the reason that its action would be impaired by the dirt lodging in between the coils and filling up the spaces to such an extent as to render the spring inoperative.

It is the object, therefore, of the present invention to remedy this defect by the employment of a rubber ring to act as the spring, and upon which the ball of the handle is seated, and also a peculiar]y-constructed confining plate for the ring, whereby the same is held in position to insure its perfect action in keeping the ball pressed up against the interior side of the socket-plate to hold the handle in its adjusted position, as will be hereinafter described and claimed.

In the accompanying drawings my invention is shown as applied to a brush, A designating the head, to the upper side of which is suitably fastened the socket-plate B, provided with the open slot 1). Vithin the socket-plate B is located the ball 0, which is provided with a screw-threaded shank, a, for attaching it to the handle D. The socketplate is castin one piece, and, as will be seen, is formed tapering upon its interior, as shown at c, in order to prevent as little of the ball 0 coming in contact therewith as possible, so as to reduce the frictional contact of the ball with the socketplate, thereby renderingthe handle more read ily adjustable.

The head A is formed with a' mortised seat, d, for receiving the rubber ring E, which is of greater thickness than the depth of the mortise, so as to project above the same to form a seat for the ball O. The mortise d, which is circular in shape, to conform to the shape of the ring E, has located therein a confiningplate, F, the construction of said plate being more clearly shown in Fig. 8. This plate consists of a depending rim, e, and a horizon-- tally-projecting interior flange, f, extending around the opening of the confining-plate, said plate being secured to the head by screw or other suitable fastcnings passing through ears 5 of the plate; The peculiar construction of this plate performs functions in connection with the rubber ring that are essentially important in rendering the handle readily operative to bring it in the required adjusted position.

\Vhen it is required to bring the handle D at the desired angle with relation to the brnshhead for the convenience of using it, the handle is pressed down, which will compress the rubber ring E by contact therewith of the ball 0, whereby the latter will not come in frictional contact with the interior sides of the socket; plate B, thus enabling the handle to be brought to the position required, and the elasticity of the rubber composing the ring performs the functions of a spring to force the ball up in frictional contact with the socket-plate with sufficient force to hold the handle in its adjusted position.

\Vhen the rubber ring is compressed, the flaugef of the confiningplate F prevents the rubber from expanding in a direction laterally above the confining-plate and compels it to be compressed laterally in the space'below the flange and between it and the mortise d and against the depending rim c, the rubber ring perforating two functions-viz., a spring and a Ice In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
