JAMES MILLEN DICK, OF BUFFALO, NEW YORK.

- -UIMPRo'vMENT |N WooL-DRlERs.

Specification forming part of Letters Patent No. 116,032, dated June 20, 1871.

To all whom it may concern:

Be it known that I, JAMES MILLEN DICK, of Bualo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Wool-Driers, of which the following is a specication:

N atnre of the Intention.

This invention consists of a machine so constructed that the wool is squeezed or pressed by means 'of rollers to expel moisture, then subjected to a blast of cold air and acted on by pickers, for the purpose of drying, as hereinafter fully described.

General Description.

In the drawing, Figure l is a vertical longitudinal section. Fig. 2 is a plan with the fantrunk removed.

A represents the frame, which may be of any ordinary or convenient construction. Near one endis mounted a fan-case, B, having a trunk, B', which extends to nearly the other end of the machine, where its end turns downward, as shown in Fig. l. A fan, C, in this case, constantly impels a current of air through the trunk. An air-space or passage, D, extends from the mouth of this trunk downward and backward under the fan-case, and terminates in a aring mouth, D', where the wool is discharged. A picker, E, made to revolve in anyk suitable manner, is mounted in the air-space or passage D, being in such a position as not to break the current of air downward from the trunk, but to catch the wool at the bottom as it is drawn down. This picker revolves against the edge of the blast. A stationary pickerbed, E1, is situated above this cylinder, and one, E2, below. All these parts are' armed with radial pins or teeth o, which intermatch in the revolutions ofthe cylinder or picker E. A pair of wringing-rollers, Gr G', is situated at a proper position in front of the mouth of the fan-trunk. These are pressed downward by screw b acting upon adjusting-bar c in a `manner similar to clothes-wringers. Outside these rollers is situated an endless apron, H, passing over rollers d d', as clearly shown in Fig. l. A clear space, f, is left between the end of the endless apron H and the wringing-rollers, which will allow the expressed water to pass downward without striking upon the apron or its contents. The aring mouth D', which discharges the ber, has a series of holes, g g, at the top, which allow the entrance of fresh air at that point.

Operation.

The wool is fed onto the endless apron H, which conveys it to the wringing-rollers Gr G. Inpassingbetween these the water is expressed and runs down through opening f without falling upon the apron, as before stated. Thermoment the Wool passes inside the rollers4 the current of cold air through trunk B' forces it downward upon the picker-bed E2, whose teeth serve as a stop to its further progress. Here it is caught by the picker E and carried upward and backward in the edge of the blast, which blows in the opposite direction from which the picker is running.. This action against the blast aids very greatly in the drying process. After being carried around it passes through the lintermatching teeth of the stationary picker El, and is carried down to outside the picker-bed with the fibers thoroughly separated. Here it receives the full impetus of air through the passage D, and is nally blown out at D' thoroughly dried by its contact with the current of air in passing through.

In this quick drying the result is much -better than in a slow process, as the ber is leftwith a greater degree of life and elasticity, and, therefore, it has greater strength and is capable of greater wear. The holes g g in the top of the discharge-mouth D' aid the drying very materially, as the current inside sucks through these a large quantity of fresh air. vThe picker E not only separates the bers of the wool from their matted condition, but also opens them, so as to give the best e'ect to the air.

Claims.

What I claim as my invention is- 1. In a wool-drying machine, afan, C, and trunk B' B, so arranged that the current of air is impelled against the wool at its entrance and is blown out, as herein described.

2. In a wool-drying machine, in combination with the fan-trunk B B' and fan O, the revolving' picker E and picker-beds E1 E2, arranged and operating as herein set forth.

pioyed in a wool-drying machine in the manner and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing Witnesses.

JAMES M. DICK.
