. INTERMEDIATE CONVEYEB; SUGAR-CANE MILLS.

To all'whom it ma concern:

Be it known t at I, ARTHUR FREDERICK Ewenr, a subject of the King of Great Brits ain and a resident of the city and county of llonolulu and Territor of Hawaii, have invented certain new an useful Improvements in Intermediate Conveyors for Sugar-Cane Mills; and I do hereby declare the following to be a full, clear, and exact enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements, in intermediate conveyers such as are. used between spgar-canemills for transporting the crushe from one mill and feeding the same to the succeeding mill of the train.

Its object is to provide a conveyor of this character which shall be self contained and easily detachable so that it can be quickly removed. I

aprons or canvas belts, which heretofore have usually been employed and which cause delays due to the'breakage of the chains or slats or to the stretching or bagging of the belts, and which are otherwise objectionable on account of leakage through the apron, and the inversion of sugar which occurs due to the souring of juices absorbed by the canvas belts or in the cusha cush retained, by the chains of the slut, ,f aprons.

This invention contemplates an inter- 1 mediate conveyor comprising a detachable 1 water tight trou h between two sugar-cane :mills', means wit in the trough for engagpagasse so as to drag or aid the movement ofthe same through the trough, means for i? regulating the distance between the dragging means and the bottom of the troug means for maoerating the bagasse while in the trough, scrapers for the mill rolls supported b the trough, and certain other features, ad of which will. hereinafter more fully appear. The invention consists in the novel construction arran ement and combination of parts as hercina"ter described. In the accompanying drawings, forming a art of this specification, Figure 1 represents 131 side elevation an intermediate conveyer Specification of Letters jEatent.

Application filed October 21, 1914, Serial No. 867,890. Renewed January description of the invention, such as will cane or bagasse discharged Another object is to eliminate the slat ing the top of the layer of crushed cane or II Patented Feb. 8 1916. 3, 1916. Serial No. 70,075.

embodying a preferred form of my inventron. F g. 2 is a longitudinal sectional elevation of the same two three-roller sugar-cane mills. Fig. 3 is a detail showing a portion of one of the drags or flights.

Referring to the drawings, the three-roller sugar-cane mill the bagasse from whichis to be conveyed and fed to the succeeding mill B. The trough C of'the conveyer, which is'removable and preferably water ti ht, is composed of the bottom plate 5 secure to the angles 6 and .7 riveted to the side plates 8 and 9 near their lower edges respectively. The forward ends of the side plates 8 and 9 are provided with short pieces of angle 10, which are halted by the bolts 11 to the checks of the mill A. The saddle brackets 12, bolted to the side-caps of mill A, support the trough C at its lowest portion. The rear or upper end of the slightly inclined trough C rests on the upper edges of the plates forming the short feed chute of mill B. The upper end of the bottom plate 5 is bent downward at 5 to overlap the corresponding chute plate of the mill B. The side plates 8 and 9 are stiffened by the angles 13 and 14 rivetedto the outside of said plates near their upper separators. t a l 1 The shafts 16 and 17 are each journaled in a pairof boxes l8 and 19 respectively on opposite sides of the conveyor trough C, said shafts passing through holes in the said plates. The boxes 18 and 19 are adapted to slide in the frames 20 and '21 secured to the side plates 8 and'9 and are adjusted bythe screws 22 and 23 respectively. Sprockets, 24 25 are secured to the shafts 16 1'! respectively, over-which the endless strands of link belt 26 are passed. Drags or flights 27 are secured transversely These drags or flights 27 may have zig-zag edges (Fig. 3) or other shaped edges to adapt the same to engage the bagiasse in the trough C. 'Iheshai't 16 is revolved in any A represents when applied between edges respectively, and also by the transverse angles 15 which act as to these link belts 26.

well known mehpen so that the link bolts;

26 will move in" the direction as ehown'by the arrows, forexafflple, from the top roller of mill B by means of the sprockets 28 29 connected by the link belt 30. One or. more sets of idler pulleys 31 may be employedto depress the li'nl belts 26 go th the m pipe 46,

or flights 27 may better engage the blanket of bagasse in the trough C, particularly when the mills A and B are situated so far apart that the trough is long and the distance between the shafts 16 and 17 is large.

These idler pulleys 31 are secured on shailts 32 journaled in boxes 33'adapted to slide 1n frames 34 secured to the side plates 8 and 9 and adjusted by screws 35 in the same manner as described for the shafts 16 and 17.

The upper scraper 36 for the top roll 01: mill A is secured to the bar 37 which is adapted to turn in the boxes 38 supported by the angles 13 and 14 respectively at the forward end of the trough C. This upper scraper 36 is adjusted by the the levers 39 attached to the bar 37 and the turnbuckles 40 attached to these levers 39 and to the side plates 8 and 9 respectively. The lower scraper 41 for the discharge roll of mill Av is secured to the bar 42,.which is adapted to turn in the boxes 43 bolted to the side l plates 8 and-9 respectively: This scraper fl ls similarly adjusted by means of the levers 44 andthe turnbuckles 45, as shown. The rear end 41 of the lower scraper-41 may be bent'pr curved upward, as shown, so as to raise the bagasse slightl passing off from this scraper and r0 .onto the bottom plate 5. Maceration iquid maybe applied to the bagasse in the trough C as it leaves the scra or ,41 by means of the above the forward end of the bottom plate 5 and under the rear end 41 of the scraper. 41. Maceration may alsobe applied to the bagassenrhileit is passingi over the lower scraper 41, by means of t e pipe 47 with holes 47 supportedby the side plates 8 and 9, as shown. r 1

Inoperation, thecrushed cane or bagasse discharged'from mill A'is pushed rearward over the lower scraper 41 and drops onto ,the vforward end of the bottom plate 5, Whereup0n'the drags or flights 27 engage this layer or blanket of bagasse and aid its movement along in the trough C until it arrives at and drops cit from the rear end 5 of th bottomplate 5 and is fed to the mill B. The distance between the drags, or flights 27 and the bottom plate 5 may be. adjusted by operating the screws 22, 23 and 35, so as to suit the thickness of the layer or blanket of bagasse in the trough C. Maceration may be applied to" theba asse in the trough C as previously described.

It will now be noted, that the removable before conveyer trough being water tight prevents leakage of juice or maceratwn liquid.

By disconnecting thedriving chain 30 and,

h per and lower scrapers 36 and 41 and the maceration pipes 46 and .47, is thus removed with, the trough C.

2. An intermediate conveyer for sugarcane mills comprising, a removable trough, means for engaging the blanket of bagasse within the trough to aid its movement rearward in-the trough, upper and lower scrap ess for the rolls of one mil]. with adjusting means for same supported by the trough, and a maceration pipe located between the bottom of the trough and the'rear end of the lower scraper, substantially as described. provided with holes 46, located 3. An intermediate conveyer for sugarcane mills comprising, a removable trough,

upward, substantially as and for the purpose described.

4. In an lntermediate conveyer for sugarcane mills, a removable trough, and maceration-pipes supported by and removable with said trough.
