DEPROV'EMZENT IN MACHINE FOR WASHING- WOOL.

The Schedule referred to in these Letters Patent and making part of the same.

To all to whom it may concern:

Be it known that we, J ORN MCNAUGHT and WIL- LIAM MGNAUGHT, Jr., both of Rochdale, in the county of Lancaster, in England, engineers, have invented certain new and useful Improvements in Machinery for Washing Wool and other Fibrous Materials, and we hereby declare the following to be a full, clear, and exact description thereof, reference being had to the Our improvedmachinery consists of Ya series of two or more rakes, for traversing the wool or other fibres along the cistern to an inclined plane, up which they are moved by an improved cradle, and delivered to a series of rollers, which convey them to the squeezers.

Figure 1 is a longitudinal section of one of our improved machines for washing wool or other fibrous maf terials.

Figure 2 is a plan of the same.

a is the trough.

b, a perforated false bottom in the same, supported by stays c.

d is a side-shaft, supported in bearings xed to the trough, for giving motion to the rakes or propellers e e, the last of which'may have two sets of prongs.

These rakes convey the wool or other fibrous material to the inclined plane f, up which the wool or other material is carried, by means of the cradle or lifter g, to the small rollers h h, and by them forward to the squeezer-rollers i i.

if is a frame, of iron or any other suitable material, to which are xed teeth or prongs of the cradle or lifter g, for raking or carrying the wool up the ineline j'.

c c are brackets, fitted to the frame g', between which the crank k acts, to give it the requisite to-andfro motion.

The up-and-down motion is given to the cradle or lifter g by the earns kl, which, in revolving, act on .the under side of the top rail of the frame g.

One pair of cams is fixed to the same shaft as the crank k, and the other pair is fixed to the shaft k2.

The frame lf is supported on the cams, which prevent the teeth or prongs of the cradle or lifter from' bearing on the bottom of the inclined plane j'.

The points of the teeth of the last of the propel- 1ing-rakes e work Ain the curved end of the false bottom b, and lift th'e wool or other material on to thc lower end of the inclined surface f, through which the series of prongs n shoots up, to retain it.

These prongs are formed upon arms fixed to the shaft a, and pass through holes in the bottom of the inclined surface. A

The shaft n is made to oscillate by a cam on the shaft k2, the motion of which is transmitted through the rod n2, jointed to the lever a3, fixed to the shaft u.

The cam is formed to lift up the prongs quickly,

when the fibrous material is deposited on the inclined surface, and to withdraw them into the position shown in fig. 1when the cradle or lifter g is about to drop over them.

Thewool or other material to be operated upon is put into the cistern a, in which is the necessary liquid.

The side-shaft (l, being set in motion by the pulley j on the driving-shaftj, imparts the requisite motion to the rakes or propellers e in the following manner:

The shank of each rake, e, 'passes through and is fastened(to a socket, e?, in which socket the shank of the rake is adjustable, andI swivels on the crank es, lixed to the crank-shaft e, which is driven by mitrewheels from the side-shaft cl.

The upper end of each shank el is jointed to a link, e5, whose fulcrum, e6, is adjustable; and, by moving this fulcrum nearer to or further from the shaft e4, the sweep of the rakes is varied.

The combined action of two or more of these rakes. agitates the fibrous material, and carries it along the bottom of the trough a, and leaves it on the bottom of the inclined plane f, where it is held, by the rising of the prongs n, until it is carried forward bythe cradle or lifter g.

This cradle or `lifter g, as before described,is.worked bythe cams K K and the crank 7o, and is so actuated that, after the wool has been deposited on the bottom of the incline f, it drops upon it, and drags it up the incline to the extent of its stroke. lThe cradle then rises, and returns over the wool, to again drop upon it, and to again drag it up, the retaining-prongs withdrawing immediately upon the cradle dropping upon the wool.

The cams K K are made to revolve by the wheels ll, which receive their motion from the wheel m, fitted on the shaft j.

The wool or material, being carried, by the cradle g, up the incline f, is pushed over, at the end, on to the rollers h ZL, which are covered with sheet-brass or other suitable metal or material, and revolve in the same di rection, that is, toward the squeczer-rollers i t'.

The small rollers h h are driven at accelerated speeds in regard to veach other, increasing in speed asthey approach the squeezer-rollersq.

The water pressed from thewool or other fibrous material, as it passes between the squeezer-rollers, falls into the trough z, from whence it is conveyed, through the pipe z', into the cistern a.

Having thus stated the' nature of our invention, and described the manner of performing the same,

lVe declare that what we claim herein as new, 'and desire to securehy Letters Patent of the United States, is v l. The connecting-link ei, with its adjustable fulcrum, combined with the rakes, for regulating the sweep ofthe points thereof, substantially as specified.

2. The inclined plate j', forming part of the trough a, combined with the cradle or lifter g, substantially as specified.

3. AThe arrangement of the crank 7c, brackets c', cams k1, and bars g', for actuating the cradle, substantially as speeied.

4. The retaining-prongs n, combined .with the inclined bottom f, and actuated substantially as specied.

5. The combination of the cradle g with the in- In testimony whereof, we have hereunto set our v' hands, before two subscribing Witnesses.
