KISEL K. KAITA, 0F LAI-IAINA MAIN, TERRITORY OF HAWAII.

SUGAR-REFINING APPARATUS.

Application filed October 18, 1917.

To all whom it may concern:

Be it known that I, KrsnL K. KAITA, a citizen of the United States, residing at Lahaina Main, in the Territory of Hawaii, have invented certain new and useful Improvements in Sugar-Refining Apparatus, of which the following is a specification.

This invention relates to sugar refining apparatus, having for its primary object to provide a machine which is capable of refining a great amount of sugar in a comparatively short time, and which may be kept continuously in operation.

A further object of the invention is to provide a refining machine whichefliciently works the mass delivered thereto so as to separate the molasses from the crystallized matter without waste.

A still further object of the invention is to provide a sugar refining machine of that type wherein a rotatable drum is employed, and which is equipped with a novel means for introducing the mass to the interior of the drum and for preventing the mass adhering to the drum in uneven quantities, which is provided with means for keeping the mass at all times agitated during the refining process, which employs novel means for moving the charging and agitating mechanism through and out of the rotatable basket, and which will prove thoroughly efficient in practice.

With these objects in view together with others which will appear as the description proceeds, the invention resides in the novel formation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims.

In the drawings Figure 1 is a side elevation. of a sugar refining machine constructed. in accordance with the invention,

Fig. 2 is an enlarged longitudinal sectional view taken through the sugar refining machine,

Fig. 3 is a transverse sectional view taken through the casing upon substantially the line 3-3 of Fig. 1,

Fig. 4 is a fragmentary end view of the machine,

Fig. 5 is a detail view of the scraper,

Serial No. 197,312.

Fig. 6 is a similar view of the comb apparatus,

Fig. 7 is an enlarged. fragmentary side elevation of the gearing for the mechanism, and Fig. 8 is an end view illustrating the gearing.

Referring now particularly to the drawings, 10 indicates a hollow cylindrical casing, being closed at its forward end by a allel with the shaft 12 are trackways 1a,

which support the ends of a carrier bar 15. This carrier bar has mounted intermediate its ends a standard 16, the upper end of which has fixedly secured thereto a sleeve 17 inclosing and capable of moving longitudinally upon the shaft 12. This sleeve is relatively long, and is provided with a pair of spaced flanges or

heads

18 and 19, upon the former of which is rotatably mounted a ring 20 of relatively large diameter. The flange or head 19 is of greater diameter than the head 18 and is equipped at its edge with a ring 21, the said ring being of slightly greater diameter than the ring 20.

Secured as at 22 upon the shaft 12 and within the casing 10 is a basket or drum 23, one end of which is closed as at 24 while the rear end is open as shown. This drum is of less diameter than the casing 10' and is supported at its rear end upon a bearing 25 affixed to the interior of the said casing. The circumference of the basket or drum 23 is foraminated, so that the liquid contents thereof may pass through into the casing 10 and the latter is equipped with a discharge spout or outlet 26 at its forward end. It will be observed that the bearing 25 is secured to the interior of the casing 10 by an annular member 27, and this annular member constitutes an abutment for the ring 21 carried by the rear head 19 on the traveling sleeve. The ring 20 is of substantially equal is in mesh with a pinion 33 carried by a rod 34 rotatably mounted in suitable bearings 35 upon the board 28. The rods 34 project rearwardly from the casing, and extend beyond the rear head 19 of the sleeve, being equipped at its rear extremity with a hand wheel 36. It is obvious, therefore, that the blade 31 constituting the scraper may be moved radially inwardly or outwardly of its supporting bar 28 by rotating the hand wheel 36. By so adjusting the scraper blade,

it is obvious that the outer edge of the same may be moved into or out of engagement with the interior surface of the rotatable basket or drum 23.

The outer edge of the plate 29 has rotata' bly mounted thereon and coextensive therewith a rod 37, which is provided with a. plurality of comb teeth 38, the latter terminating at their outer ends close to the interior surface of the rotatable drum 23. The rear end of the rod 37 is equipped with a crank arm 39, and to which one end of a link 40 is connected. The link 40 is connected at its opposite end to a crank arm 41 carried by a rotatable shaft or rod42 mounted in suitable bearings upon the sleeve 17. The said rod 42 projects rearwardly beyond the head 19 and is provided with a handle 43. By rotating the rod 42, it is obvious that the comb rod 37 will be simultaneously rotated, whereupon the teeth 38 may be moved toward or away from the inner surface of the rotatable drum.

The rear end of the main shaft 12 is provided with a gear 44, which is in mesh with a similar gear 45 mount-ed upon a counter shaft 46. The counter shaft 46 is provided with a clutch indicated generally at 47, and by means of which a ower connection between the shaft 12 anc the rear end of the counter shaft 46 may be made or broken as desired. The rear end of the shaft 46 has secured thereto a gear 48.

Arranged in spaced parallel relation to the counter shaft 46 is another counter shaft 49, to which a gear 50 is secured. v The forward end of the shaft 49 is also provided with a gear 51 in mesh with a gear 52 on the rear end of a jack shaft 53, This ack shaft may be supported in any suitable manner, and is provided adjacent its forward end with a worm 54. The worm 54 engages in an internally threaded opening in the limit in one direction, a

transversely disposed bar 15, and in such .manner that rotation of the shaft 53 will in mesh with the gear 56, and the bracket may be operated upon the shaft 49 by moving the hand lever 58. The gear 56 is at all times engaged with the gear 50, while the gear 57 may be moved into or out of mesh with the gear 48 on the counter shaft 46. When the hand lever 58 is moved to its power connection between the

shafts

46 and 49 will be established through gears 48, 5.6 and 50, while mlovement of the lever 58 to its limit in a reverse direction establishes a connection between said shaft through

gears

48, 57, .56 and 50. This particular arrangement makes it possible for the counter shaft 49 to be rotated selectively in opposite directions.

The head 19 upon the slidable sleeve is provided with a pair of filling hoppers 59, which are in communication at their inner ends with the space between the heads 1819 and are enlarged and turned upwardly at their opposite ends in the rear of the head 19 to receive matter to be introduced to the rotatable drum.

In operation, the motor 13 is started, and the drum 23 at once begins to rotate. The raw material is introduced to the interior of the drum by being poured into the hoppers 59. It is to be understood that the discharging apparatus which is carried by the sleeve 17 is moved into the drum prior to the charging operation. The mass delivered to the interior of the drum through the hopper 59 is deposited upon the boards or

plates

28 or 29 and drops upon the interior of the rotating drum. The scraper blade 31 is adjusted so as to keep the mass evenly distributed upon the interior surface of the drum, and the knives or comb teeth 38 at the bottom of the drum keep the mass agitated so as to cool or dry quickly. Moisture in the mass is relieved therefrom byv centrifugal force as the drum rotates, and passes through the foraminous drum and into the casing 10, being led therefrom through the outlet or discharge pipe 26. After the refining process, the clutch 47 may be thrown in, and the lever 58 operated so as to cause the worm 54 to rotate in a direction to move the bar 15 rearwardly. This movement causes the discharging apparatus to be withdrawn from the rotating drum, and the sugar will pass from the rear or open end of the drum or basket.

From the foregoing it is obvious that I have provided a refining apparatus which is of an extremely simple construction, and which operates so as to rapidly separate the molasses from the crystallized mass without waste.

While the present is a disclosure of what is believed to be the preferred embodiment of the invention, it is to be understood that the invention is not limited thereto, as various changes in the minor details of con struction, proportion, and arrangement of parts may be resorted to if desired without departing from the spirit of the invention as defined by the appended claims.
