Specification of Letters Patent.
Patented March 9, 1909.
908. Serial No. 433,187.
T0'aZZ w7wm timely concern:
Be it knownthat we, JonN MCNEIL and CHARLESUQHCNEI'L, B. So, subjects of the de nts of Govan, in the county of Lanark, Scotland, have invented certain new and useful Improvements in Connection with Sugar- Cane Mills, and of which the following is the specification.
This invention relates to sugar-cane mills of the type in which some of the rolls have formed on their surface ridges or teeth with ferentially around the rolls that when the rolls are geared together the circumferential teeth on one roll project into the circumferential channels in the other roll with which it engages. This type of roll is efiicient in the cane and also allows for a free escape of the uice down the circumferential channels further as the channels are circular the possi hility of their becoming clogged hyportions of the broken cane or me'gass sticking therei is prevented by scrapers so carried that they project into the channels; but these rolls are not so efficient as they might be in that the teeth are apt once they have split the ortion of cane between them to slip through it without dragging it forward. In order therefore to overcome this objection and obtain elficientbiting ell'cct on the cane, which will insure a regular forward. move ment thereof, the roll, according to the present invention, has formed upon its surface series of short zig-zag grooves extending longitudinally from end'toend of the roll and so spaced apart around the circumference of the roll that there is always a portion of one of the series of grooves opposite the point where the rolls intermesh.
In order that the invention and the manner of performing the same may be properly understood there are hereunto appended two sheets of explanatory drawings showing in Figure 1, Sheet 1, an elevation and in Fig. 2, an end elevation of a sufficient portion of a roll to illustrate one example of the im provements Fig. 3, Sheet 2, being an elevation similar to Fig. 1 illustrating a second example.
According to the example shown in Figs.
1 and 2, the roll is of the type in which ridges or teeth A with intervening channels B are arranged circumferentially around its surface, so that when two of these rolls are geared together the circumferential teeth A on one roll project into the circumferential channels B in the other roll with which it engages.
' In order to obtain an efficient biting effect on the'r-ane which will insure a regular forward movement thereof, the roll, according to the present invention, has formed upon its surface. series of short zig-zag grooves C extending longitudinally from end to end of the roll, the ends of the oppositely angled sides of each series of z'ig-z'ag grooves all merging into each other so thateach groove is continuous from end to end of the roll. The grooves C are so spaced apart, around the circumference of the roll that there is always a portion of one of the series of grooves opposite the point where the rolls intermesli. The number of zig-zag grooves in oach of the soriesvin the length of each roll depends, of course, on the length of eaclrside of the zig-zag and the angle at which each side is set to the other and both the length and angle, also the distance the grooves C are spaced apart around the circumference of the roll may be varied within such limits as will insure that no portion of the grooves on both rolls are opposite the point where the rolls intermesh at the same time. These zig-zag grooves C are preferably formed with what is the forward side D, in the direction of rotation of the roll, more nearly tangential to the surface of the roll than the other and rear side E which approaches the radial, so that this latter side of each groove may be said to act as an upstanding tooth eirtending more or less transversely to the direction of the length of the cane; and this portion E, of each groove C, when at the point where the rolls intermesh, bites into the cane but does not shred it, as the circumferential teeth A are apt to do. The action of these grooves (3 therefore insures that the cane is pulled through between the rolls with the regular forward movement desired.
The example of the invention shown in Fig. 3 dillers from the example hcreinberore described with reference to Figs. 1 and 2 only in that the portions of the grooves C, in each series, angled in one direction, are so or-- ranged that their ends are opposite the sides -of the portions angled in the opposite direction. 1
What we claim is l. A roll for sugar cane mills having circumferential teeth with intervening channels formed on "s surface, in combination with zigzag grooves extending longitudinally of the roll and arranged to intersect said circumferential teeth at all points circumferentially of the roll, substantially as described.
2 A pair of intermeshing rolls for sugar cane mills having circumferential teeth with intervening channels formed on their re-' spective surfaces, in combination with a series of short zigzag grooves extending longitudinally from end to end of each roll, the length and angle of each side of each zigzag groove and the distance the grooves are spaced apart around the circumference of each roll being such that no portion of the grooves in one roll is opposite the groove in the other roll at the oint where the rolls intermesh, substantial y as described' 3. A roll for sugar cane mills having circumferential teeth with intervening channels formed in its surfacejin combination with a series of short zigzag grooves intersecting said circumferential teeth and extending from end to end of the roll, the ends of the L oppositely angled sides of each series all merging into each other, substantially as described.
4. A roll for sugar cane mills having circumferential teeth with intervening channels formed in its surface, in combination with a series of short zigzag grooves intersecting said circumferential teeth and extending from end to end of the roll, theposition of the grooves angled in one direction being so arranged that their ends-are opposite the sides of the portions angled in the opposite direction, substantially asdescribed.
5. A roll for sugar cane mills having circumferential teeth with intervening channels formed in its surface, in combination with a series of short zigzag grooves intersecting said circumferential teeth and extending from end, to end of the roll, the forward side of the zigzag grooves being -more nearly tangential to the surface of the roll than the other and rear side which approaches the radial, as described.
In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses.
