IMPRovElvu-:N'r IN TEASELGRADING MACHINES.

The Schedule referred to in these LetterB-Patent and making part ef the name.

To all whom it may concern Be "it known that I, GEORGE A, BRROUGH, of Providence, in the State of Rhode Island, have'invented a new and useful machine, which Icall a Grad ing Machine for Grading Teasels, an article used by wooleu manufacturers for raising the nap on cloths and other articles; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, in which like parts are represented by like letters in the several figures, andin which- Figure 1 is top view;

Figure 2 is a sectional View; and Y Figure 3, a partial top View of a straight machine, which was rst made but not considered as good as fin. 1.

DThe machine is made of iron or other materials, in a circular form, about four feet across the top, with about forty slots or spaces graduated from threefquarters of an inch to one and a half inch wide and three inches long, with a suitable number-of caps.

In the drawings, iig. 1-

a represents the seat for the operator.

b, graduated slots.

c, caps.

d, radial arms.

e, a rotary shaft.

t', supports.

j is a fixed exterior flange. The widthof the slots b is regulated by sections sof an annular ring concentric with the flange j, these sections to 'be adjusted inward or outward by a parali lei movement through'slots k in the same and setscrews l, by which they are secured to the centertable or platform.

The machine is set in motion by power being applied in any suitable manner to the shaft e, iig. 1, and the operator, at a, places the teasels in the cups with their stems in the `supports 'i to keep them in a perpendicular position as' they rotate over or through the graduated slots, until they reach one suiiciently wide to allow of their passing through, as shown in fig. 2, f representing a teasel passing over, and g one passing through a slot, suitable receptacles A being provided underneath to keep the sizesseparate.

What I claim as new, and desire to secure by Letters Patent of the United-States, is 1. In a teasel-grading machine, the graduated slots or spaces formed by the annular flange j, and the adjustable sections l, for the purpose set forth.

2. In combination with said slots, the radial rotary arms d, caps e, and supports t, arranged as and for the purpose set forth.
