IMPROVEMENT IN MACHINES FOR Specification forming part of Letters Patent No OPENING AND CLEANING COTTON.

. 190,107, dated April 24, 1877; application filed March 3, 1877.

To all whom-it may concern:

Be it known that we, WILLIAM E. WHITE- HEAD, of Miles Plattin, county of Lancaster, England, and ABEL T. ATHERTON, of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain Improvements in Machines for Opening and Cleaning Cotton, of which the following is a specification:

Our invention relates to an improved de vice for removing the dust and other foreign substances from cotton; and consists of an improved cylinder, located between the heater and collecting-cages, operating either in connection with a series of bars projecting from the cover of said cylinder, upon the inside of the cover, or without the connection of said bars, as may be desired.

The accompanying drawing represents our invention.

A is the frame of the machine. B is the beater. G isthe feed-rolls. D is the screen, beneath the beater. E is a door opening into the dust-chamber beneath the improved cleaning-cylinder. F is one of two dustpipes, exactly alike, and disposed on both sides of the machine. H shows the location of the upper Wire collecting-cage, and J the lower Wire collecting-cage. K shows the relative position of the exhaust-fan, which removes the air generated by the beater, and at the same time causes the cotton, by such exhaustion of the air, to collect upon the wire cages. L andT are two girts of the machine, by means of which a dead-air chamber is formed beneath the improved cleaning-cylinder. Mis the improved cleaning-cylinder, so constructed that it has upon its periphery a surface'so formed as to offer an impediment to the free passage of the cotton from the beater to the collecting-cages.

This surface may be formed in various ways,

to obstruct the free passage of the cotton,

other than that herein shown and described.

The object of said rough surface is for the purpose of collecting from the cotton the dust and other foreign substances previous to the cotton being collected on the cages.
