IMPROVEMENT IN CEN TRIFUGAL MACHlNES.

' Specification fbrniing part of Letters Patent No. 210,657, dated December 10, 1878; application filed March 4, 1878.

Be it known that we, XVILLIAM T. BELL, of the city, county, and State of New York, and

'Josnrn GOLDSACK, Jr., of Jersey City, Hudson county, in the State of New Jersey, are

the inventors, jointly, of an Improved (Jentrit'u gal Sugar-Drainin g Machine, of which the following 1s afull, clear, and exact descrip- ,tion, reference being bad to the accompanying drawings, forming tion, in which Figure 1 is aside elevation of a machine embodying our invention, a portion of the wall of the chamber inclosing the basket bepart of this specificaing cut away to disclose the basket. Fig. 2is' ertures in its sides open 5 and Fig. 4 is a plan,

partly in section, on the lineac a", Fig. 3, of the basket, the gate which we preferably employ to open and close the dischargeapertures of the basket being removed.

Our invention relates to centrifugal Inachines for draining sugar; and it consists, first, in a basket for such machines having the apertures for the discharge of the sugar therefrom in the side or circumferential wall thereof second, in the peculiar gate and its operating mechanism which we employ to open and close the dischargeapertures of the basket, all as hereinafter particularly set forth, and more at length recited in the claims.

A is the basket of our improved machine, and is constructed with the closed or solid bottom a, and has its circumferential wall perforated and lined with netting or gauze, as is usual in machines of this class. The basket is mounted upon a vertical drivingshaft, B, which has a hearing at its lower end in a step, I), on the platform or base M, and at its upper parta bearing in the frame N at I), as shown. The basket is inclosed by the customary chamber 0, to receive and carry off by a gutter, c, the molasses drained from the basket, said chamber being arranged as shown, supported by columns 0, fixed in the machine-platfbrm. The shaft B is rotated by ,means of the friction-wheels Z) and b and balance or guide friction-wheel I), as shown, the shafts of the wheels I) and b having bcarin gs in frame N, and one or both being driven by a pulley, as at If. The frameN and the frictiongearing are preferably arranged below the basket, as shown.

In the circumferential wall of the basket, and preferably in the lower portion thereof,'we make one or more of the wide apertures D, and we find it preferable to have that portion of the said wall in which these apertures are made continuous, as seen at (0 and without the perforations or netting lining which vat a It is desirable that a number of these apertures D should be ranged around the wall of the basket, as shown in the drawin Oommunicatin g with these apertures are arranged the spouts or chutes D, one upon each side of the basket, and mounted on the frame of the machine. Only one of these chutes is shown int-he drawings.

We find that the device shown in the-draw in gs is to be preferred for opening and closing the apertures D.- This consists of a gate or valve, E, preferably conical in shape, as shown, arranged to fit horizontally in the basket and to have a vertical movement within the basket. An annular projection, a is formed upon the interior of the wall of the basket, above the line of the apertures D, and against this the rim of the gate or valve E abuts and rests when the disk is raised in the position shown in Fig. 2. When thus raised the apertures D .are closed to the upper part of the basket, and the contents of the basket cannot escape through said apertures. When it is desired to open said apertures D, the gate or valve E is lowered until its rim is below the line of the said apertures, when it is evident that the con tents of the basket may be readily discharged through the apertures D.

It will be perceived that this arrangement of parts is admirably adapted for a sugar raising the gate or valve E, as stated, the wet sugar is introduced into the basket. \Vhen the draining is completed and the rotation of the basket has ceased, the apertures D are extend over the other portion of said wall, as

drainer. The apertures D being closed by opened by lowering the disk, and the sugar which has collected upon the wall of the basket is detached therefrom, and may be readily discharged from the basket through the apertures D into the chutes D, the conical shape of the disk aiding the ready discharge, and cars being conveniently placed at the lower ends of the chutes the sugar is received by them and may be conveyed away.

Various devices may be employed to raise and lower the gate or valve E but we prefer the following, as shown in Figs. 3 and 4.

Upon the bottom of the basket, under the disk, is fixed a block or standard, 6, and upon the sides of this block are pivoted the levers 0, each of which is provided with a pin, 6 engaging a slot, 6 in the plate a". This plate is on the end of a .hollow shaft, 6 on the ex terior of which, by means of a central opening in the disk, the disk slides vertically. Through this hollow shaft e rises vertically from the block 6 the post 0, which has a screw-thread, as shown.

To the upper end of the shaft 6 is fixed a nut, 6 which works on the post a, and above this is a jam-nut, e, on theend of the post.

To raise the gate or valve E, the slotted plate 6 is, by means of the shaft 0 and its nut 6 turned upon the post c in one direction, so that the pins 6 in the levers 0 will swing the long arms of the levers upward, and said arms,

bearing against the under face of the disk, will raise the disk to the desired height and support it, when the, parts may be secured in position by the jam-nut e.

To lower the disk the jam-nutis loosened and the plate a turned in the reverse direction, when the levers willfall and the disk descend.

At F is seen the brake which we employ to check the rotation of the basket. It consists of a band or strap, as shown, which encircles a ring or hub, f, projecting downward from the base of the basket, the brake I being secured at one end to a pin set in the machineframe, and closed, down upon the hub f by means of a bell-crank lever, f to which its opposite end is hinged, said lever being pivoted on the machine-frame, and operated by a lever, f through a connecting-rod, f said leverf being on the end of a shaft, f arranged in bearings at the side of the apparatus, so

.as to be convenient to the operator,

To prevent the shaft B from swaying in its upper bearing, b, we provide the spring-bolts b arranged radially about the said shaft, and seated at their outer ends in studs or an annulus, as shown in Fig. 2. Thus, when the shaft tends to sway from a vertical position during the rotation of the heavy basket, the spring-bolts, impinging upon it from all sides, will operate to force and hold it in proper po sition in the bearing b.

Upon the shafts of the friction driving-wheels b and b are arranged the coil-sprin gs d, which bear at one end against the perimeter of the wheel, and at the other in suitable recesses it against the frame of the-machine, in which the shafts havebearings. These springs operate to press the wheels I) and 12 against the wheel I) on the shaft B, and. thus insure the constant and continuous friction between the wheels requisite to secure the proper rotation of the shaft B and its imposed weight. a

What we claim as our invention, and desire to secure by Letters Patent, is-

1. In a centrifugal sugar-draining machine, the circumferential side wall of the basket, provided with one or more openings, D, whereby the drained sugar may be discharged from the basket through said wall, as described.

2. In a centrifugal sugar-draining machine, the basket A, having one or more apertures, D, in its circumferential side wall for the discharge of the sugar from the basket, together with the gate E, whereby said apertures may be opened and closed, as described.

3. In a centrifugal sugar-draining machine, the combination, with the basket A, having the discharge-apertures D in its circumferential side wall, and the interior annular projec tion c of the conical gate or valve E, with the levers 0 provided with pins 0 engaging slotted plate 6, adapted to be revolved on its axis and held in a desired position thereon, as described, and for the purpose set forth.
