'MACHINE FOR OBTINING FIBRS FROM FIBER-BEARING SUBSTANCS.

SPECIFICATION forming part of Letters Patent No. 292,240, dated January 22, 1,884.

y Application ledNovembcr 17, I1883. (No model.)

To @ZZ whom t may concern:

Be it known that l, E. Louis Lown, Jr., of vthe city of Brooklyn, in the county of Kings and State of lNew York, have invented a new l and useful Improvement in Machines for Obtaining Fibers from Fiber-Bearing Substances, of which the following is a specification. Y

My invention relates to machines for obtaining fibers, in which are combinedabed or con- Io 4cave and a rotary cylinder arranged above and in the bed or concave; and it consists in various novel features in the construction of many of the parts of 'such machines, and in the manner 4of combining the -parts together, all' as I5 hereinafter described, and as set forth in the claims.:

f l In the accompanying drawings, Figure l is fa side'elevation of a machine embodying my invention.-v Fig. 2 is a vertical section in a 2o plane transverse 'to the axis ofthe cylinder v and just within one of the side frames ofthe machine, and Fig. 3 is a plan of the machine. Similar letters of reference designate corresponding parts in all the gures.

The principal working parts or members of .themachine are a bed or concave, A, of approximately semicircular shape, and a cylinder, which is of approximately circular shape, although it may varyA somewhat from a true 3o cylinder. The bed or concaveA, here shown,

iscomposed of a main or principal portion, which extends beneath the cylinder and upward on the delivery side ofthe machine, and which is xed in position, and an adjustable 35 portion or section, A', whichis attheentrance side of the machine. By,'entrance side77 vI mean that side on which the plants or other materials to be operated on are introduced, and by delivery side I mean that side on 4o .which the plants or materials leave the machine after being operated upon.

, B designates the side frames of the machine. They are provided on their inner sides with segmental anges or ribs a, to which the staves b, which form the fixed portion ofthe bed or concave, are secured by bolts c. b', which form the adjustable portion A of the concave, are secured to curved supports c, which are hinged at a2 tothe side frames, B. 5o The said adjustable portion A is held in place by screws d, which fit in nuts d', secured to The staves on opposite sides or faces with grooves, and

Vthrough these lugs or ears and the heads vor screws vthe adj ustable section A maybe moved or swung to vary the distance between it and the cylinder, and this without moving the main or principal portion of the bed or concave. The cylinder comprises a shaft, C, heads or circular supports C', secured on the shaft, and staves e, which are secured to the iianges c of the heads or supports O' by bolts e2, andA which form the working-surface of the cylinder.

The staves b b of the bed or concave and the staves e of the cylinder are shown as provided are reversible, so that either side or face may be presented outward for use. They maybe unbolted from their heads or supports C', reversed in position, and again secured in place. As shown, the 4grooves in what are n'ow their inner sides or faces areof finer pitch than the grooves in what are now their outer sides or faces, and this construction may render them better adapted for operating upon differentA materials. Even if the grooves or projections on both sides were of like pitch, the staves would be susceptible of longer use, for when one side became smootlithey could be reversed in position.`

' In the cylinder are pockets or cavities C2, of 8o which there may be one or more', two being shown. A description of one will apply to both. 4

In the peripheries of the heads or supports C are depressions or recesses f, and in these is seated or arranged an adjustable section. of stave, C3, which may be of metal. As shown, it is provided with lugs or ears f', and is hinged to the heads or supports C by a bolt passing 9o supports. It may have a smooth surface, or its surface may be grooved or roughened.

. At each end of the stave or section C3 is a bolt orscrew, f2, having a nut, fiwhich'is fitted and held against movementV lengthwise of the screw in a recess in the flange e of the head or support C. As shown, the nut isv concave lengthwise of the screw, and the walls -of the recess which holds it are convex; hence .the nut .is not .onlycapable of turning, but

roo may swing slightly in its recesses, to accommodate itself to the varying angles at which the "the flange and entering the side fraaie.

screw will extend as the stave or section C is moved inward and outward by turning the nut.- By moving the section C3 in or out relatively tov the center ofthe cylinder the size of the pocket or cavity C2 is increased or diminished in size. The pocket or cavity C2 greatly facilitates the introduction of material into the machine, as it affords an increased space between the cylinder and concave when the said pocket or cavity comes to the entrance side of the machine.

D designates the boxes or bearings for the cylinder-shaft C. They rest on the side frames, B, and are each provided with lateral extensions D and a downward]y-extending arm, D, in which is a slot, f/.

Through the extensions D/ extend bolts g', which pass through slots g2 in the side frame, B, as shown dotted in Figs. l and 3, and have springs g3 applied to them above the boxes. These springs hold the cylinder down with a yielding force, but still permit it to rise. Setscrews gt, inserted through the extensions D and impinging on the top of the side frame, B, limit the downward movement ot' the box and cylinder.

Through the slotted arms l)' are inserted bolts g5, which guide the boxes in rising and falling, and the lower one ot' which limits the rising movement by reason of the lower end of the slot g coming against it. The two bolts g5 aid in steadying the box and preventing its canting when it is raised off its seat on the side frame, B.

For operating upon different materials it is desirable to vary the distance between the cylinder andbed or concave at the ent-rance and delivery sides of the machine, and this is effected by shifting the boxes D horizontally.

In the side frames, B, dare three sets of holes, g, for the bolts g5, thus providing for different degrees of adjustment of the cylinder. These holes are shown in Fig. l, the bolts gi being screwed into one set.

Upon the shaft C of the cylinder is a spurwheel, E, which receives motion from a second wheel, F, on a shaft, F', and the shaft F receives motion from awheel, G, secured upon a driving-shaft, G, and gearing with the wheel F.

On the shaft G is a pulley, G2, for a drivingbelt. Obviously the shaft G and wheel G might be dispensed with, and the pulley G2 placed on the shaft F, but the motion imparted to the cylinder would not be so slow as it now is. \Vhcn the cylinder is shifted horizontally, the shaft F must also be shifted to maintain the wheels E F in gear. In this example of my invention I provide for thisI by mounting the shaft F in eccentric-boxes, l1, which are fitted and adapted to turn in seats or holes h in the side frames, B. Each box has a fiange, and is secured against accidental turning by a bolt, 1', inserted through B turning the boxes h a quarter of a turn, thd

shaft F and the cylinder may be shifted, so that the bolts gf will enter the middle s et of holes, g, and the boxes are then secured by inserting the bolts l.' in either of two holes, t i, in the side frames. Vy turning the boxes half aturn, the shaft F and cylinder may be shifted, so that the bolts r/f' will enter th'e set of holes g, farthest to the left in Fig. 1, and the boxes h are then secured by inserting the bolts i in holes Ai2 in the side frames, B. The shaft G is also mounted in eccentric-boxes 71, like those above described, secured in a like manner in different positions.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-
