TO ALL WIIOM IT MAY CONCERN:

Bc it known that I, WILLAM HAMER, of Little Lever, near Bolton, in the county of Lancaster, England, have invented a new and improved Apparatus Employed in the Preparation of Cotton and other Fibrous Materials; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this spceication, in which- Figure 1 is a vertical section of a can, having in it a. plate and spira-l spring, for assisting the removal of' the sliver.

Figure 2,"a plan of the bottom of the can.

Figure 3, aplan of the movable plate only.

Similar letters of reference indicate corresponding parts.

This invention relates to the removalof the sliver from the can or coiler, and consists in placing underneath the material a. spring of metal, so that, as the sliver is4 removed from the top of the can or coller, its lower portion is raised upwards by the spring, and thereby prevents breakage.

In fig. 1 the can is'shown at a, the plate at b, and the spiral spring atc. In fig. 2, d represents a hole in the bottom of the can, for admitting air during the removal of the sliver; and in lig. 3 the plate is shown detached. The spring of metal is formed of round, square, or other shaped wires, and is made of any number of coils, according to the size of the can and weight of material, and is applied to cans or coilers of all descriptions and purposes.

When the sliver is drawn up in the usual manner, it frequently becomes uneven, stretched, torn, or broken; but the application of my improved spring and plate causes the sliver to be gradually raised up from the bottom to near the top of the delivery, and, by taking oil' the strain, enables the sliver to be made as line as possible, and prevents defects or breakage when' leaving the can.

By the employment of my improved spring arid plate usual, and thereby hold more material they also require less tending and shifting, and have less wear and tear. Another advantage is thatthe pressure upon the sliver is commenced soon after` it has begun to enter the can, andthereby enables it to be laid even and regular Having new described the nature and particulars of my said invention, and the mannerin which the same is to be performed, I claim as my invention, and desire tp. secure by Letters Patent- The spiral spring c, supporting the movable metal plate b in the can a, having the perforated bottom, all constructed and operating as described, forxhe purpose specified.

The above speciication of my invention signed by me this flfth day of March, 1867.

' WILLIAM HAMER.
