DANIEL JONES AND GEORGE T. JONES, OE PHILADELPHIA, PA.

Specification forming part of 'Letters Patent No. L15,011 7, dated November 15, 1864.

To all whom it may concern Be it known that we, DANIEL JONES and GEORGE T. JONES, of Philadelphia, and State of Pennsylvania, have made a new and useful Improvement in Burring-lVIachines; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, in which- Figure 1 is a cross-section of a barring-machine, showing our improvement. Fig. 2 shows the gearing by which the cylinders are driven.

Hitherto much of the wool has been carried away with the burr. Our machine is intended to obviate this defect.

A is the cylinder by which the clearing is done.

O O are the feed-rollers.

B and D are burring-cylinders.

E is the iiuted roller.

F is the fan. v

In the old machines the roller B is the only one used for barring. The fan, being placed on the top or bottom center of the bnrring-roller and run at a higher speed than the cylinder, thus beats the burr oi''. At the same time, however, a portion of the wool is carried away with it. In our plan, in order to save this wool we use a second burring-cylinder, D, which serves as a carding-roller to the roller B, and is run at a higher speed. A iuted roller, E, is placed on the side of the cylinder D, so that a pocket is formed between the two, which will hold the burr as long as any bers remain attached to it, the roller I), ruiming at a greater velocity than the roller E. When the ber is entirely7 taken oit', the Iiuted roller E will carry the burrs away. Should any ot' the burrs pass this roller an ordinary fan, E, will knock them oft', as in ordinary machines.

The operation is as follows: The wool is passed in between the feeding rollers c c, is then taken down by the cylinder B, and, coining in contact with the roller D, forms a carding point. A portion of the wool passes around the cylinder B and is cleared by the clearer. rIhe cylinder D, running at a higher speed than the cylinder B, acts as acarder to it, and at the'sanie time prevents the burrs from passing between them. The burrs, which fall into the pockets formed by the roller E, are cleared of all the fibers of wool adhering` to them by the cylinder D, and carried away by the iiuted roller E, and, in case any of the burrs should pass the fluted roller E, the fan E will knock them from the cylinder D.

This burring-Inachine may be attached to a card, or it may be used as a separate-machine and cleared by a brush. The drawings represent it as cleared by a cylinder of a carding-machine.

Instead oi" applying the duted roller E to the second cylinder, D, it may be applied to the cylinder B, and the cylinder D omitted altogether, or as many cylinders like D may be used as deemed expedient, and the Iluted roller applied to any oneof them. The roller F may also be omitted.

This machine may also be used equally well for ginning cotton as for burring wool.

Having thus described our improvement, what we claim as our invention, and desire to secure by Letters Patent, is

l. The combination of the iiuted roller E, or its equivalent, and one or more burringcylinders, so arranged as to form a pocket between the Iiuted roller and one of the cylinders, the roller E running at a less velocity than the cylinder D, thereby more fully cleaning the burrs.

2. The combination of the two burring-cylinders B and D, when used in conjunction with a carding engine or cylinder, A, the cylinder D being caused to run at a higher rate of speed than cylinder B, and acting to cylinder B as a clearer ofthe burrs with the small portion of wool which adheres to them, the main portion of the wool being stripped from cylinderB by the carding-cylinder A.
