IMPROVEMERT IN MACHINERY FOR CUTTING AND PREPARING FLAX, he, FOR CARDING.

Specification forming part of Letters Patent No. 5.734, dated August 29, 1848 To all whom it may concern:

Be it known that we, JOSEPH BEACH and CHARLES BEAcH, of Canton, in the State of Connecticut, THOMAS BEAcH, of Springfield, in the State of Massachusetts, and WILLIAM G. R. MOWRY, of Smithfield, in the State of Rhode Island, have invented a new and useful improvement in a machine for preparing flax, hemp, or other analogous material of long fiber so as to be carded, spun, woven, and treated in other respects like cotton or wool; and we do hereby declare that the nature of our invention is fully set forth in the following description and accompanying drawings, letters, figures, and references thereof.

Figure 1 of the aforementioned drawings denotes a top View of a machine for cutting or separating the flax into short pieces. Fig. 2 is a vertical and central section of it, taken through the cylinder of knives, and the toothed cylinder adjacent to it, A being the former cylinder and B the latter. The first is composed of a series of similar circular knives, a a a, 850., arranged at equal distance apart upon a horizontal axis or shaft, 0. The said series of knives are placed in contact, or nearly so, with the second cylinder, B, which is made of wood and covered with rawhide or other proper material, and has teeth or points b b, &c., projecting from its surface in ranges parallel to each other, the said teeth being made to pass be- The material to be cut into short pieces is thrown into the hopper and carried into contact with the knives of the cylinder A by the points or teeth of the cylinder B, and as it passes between the two cylindersit 'is reduced or cut into the short pieces in the manner required. Fig. 3 is a top view of the rollingmill in which the flax, after being cut into short lengths, is to be milled. Fig. 4 is a front elevation of the same. Fig. 5 is a vertical and transverse section of it. tical and transverse section taken through the breaker-wheels.

In said figure, F represents a large circular trough or wheel arranged horizontally and properly supported, set upon fourbeveled roll ers, and soarranged as to be madeto travel in or under a circular beveled cast-iron plate, as

represented in the model. It is made to revolve by gears or teeth L, disposed upon its circumference, and engaging with a drivingwheel, K.

L M are two breakers or heavy vertical wheels placed in the trough and upon a fixed horizontal shaft, N, as seen in the drawings. The said wheels revolve upon the ends or journals of the shaft, the said shaft being so placed and secured as to allow the said wheels or venting the flax from being thrown out of the a machine.

The object of the picker-wheel is to loosen up the mass of flax after the breaker-wheels have rolled over it and preparatory to their again rolling over it during a second revolution of the trough. The bottom of thetrough is pierced with numerous holes, Z Z, &c., to admit the escape of dust and other extraneous matter broken or separated from the flax. The circumference of the breaker-wheels is to be fluted or indented to more readily break down the flax as it passes under them.

Our process or method of preparing flax, hemp, and other material of long fiber may be set forth as follows: First, the flax or other material is taken while in the straw and in an undressed state, and is thrown into the hopper D, which is placed over the cylinders A and B, reference being had to the specification Fig. 6 is anotherverand drawings, and by giving motion to the cylinders A and B the flax or other material is carried by the points or teeth I) b b, proj ect-. ing from cylinders B into contact with the knives on cylinder A, and is cut transversely,

' or across its long fiber, by passing between the two cylinders A and B, thus reducing said flax, hemp, or other material into short pieces from two to four inches in length, or the same length as the knives are set apart on the cylinder A; and, second, the flax, hemp, or other material of long fiber, having been cut into short pieces, is thrown into the rotating trough E. The said trough is then rotated. Thus the flax or other material intended to be milled is carried round and under the breaker-wheels L M, thereby milling and pulverizing and separating the shives or woody parts from the hurd, and also the dust and other extraneous matter usually adhering to them, and also separating the fibers from one another. Thus we continue the operation of the mill until the material that is submitted to its action is reduced to that state of fineness and softness suited to the purpose for which it is designed, then it may be removed from the trough; and the mill is ready for a second operation.

(hat we claim as our invention, and wish to secure by Letters Patent, is

1. The construction and combination of machinery, as set forth in specification and drawings, as applied to cutting and dressing flax, hemp, and other analogous material of long fibers, the application of said machinery to the cutting and milling of flax, hemp, &c.,

for the purpose of dressing and preparing it to be worked in machinery similar to that in which cotton is worked, to be a new and useful improvement.

2. We do not claim cutting flax into short pieces as new, as we are aware it has been the practice of cutting the flax into short pieces in Great Britain and France for many years; but we do claim our peculiar method and process of cutting and dressing flax, hemp, and other material of long fiber to be new. We do therefore desire and petition that Letters Patent may be granted securing to us the construction and combination of machinery, as set forth in the specification and drawings in this application, to cutting and dressing flax, hemp, and other analogous material of long fiber, and our peculiar process of preparing flax, hemp, 850., so as that it can be worked sub stantially in the same manner as cotton is worked.

3. The construction and combination of machinery as set forthin the above specification and drawings, as applied to-dressing and cutting flax, hemp, and other analogous material of long fiber, and our peculiar process.
