IMPROVEMENT IN MOTIVE POWER.

Specification forming part of Letters Patent No. 41,406, dated January 26, 18(14; antedated January 24, 1864.

Figure 1 is a top view of a sugar-mill em bodying my improvement. spective view ot' the same.

A repreeents the bed-plate, and B the topplate, which, being united by posts C, constitute the frame.

The rolls l 2 3, although of less than half the diameter or one fourth of the weight of those now commonly in use, are of equal speed and efficiency of working surface.

Fig. 2 is a per- The requisite speed of grindingsurface isusually obtained by the large size of the rolls. This object I attain more efficiently and eco nomically by gearingup77 in manner following: Journaled vertically in the frame, at one side thereof, is a shaft, D, which rises above the frame sufficiently for the attachment of a sweep The shalt D earriesa large masterwheel, E, armed with two sets of cogs, one set, F, being situated on its periphery, and the other set, G, on its concavty. The mas terwheel E meshes exterior-ly in the pinions I I and I I I, of the rolls 2 and 3, and interiorly in the pinion I, ofthe roll l.

I have found it desirable to give the pinions and the master-wheel a relative proportion of one to three. These proportions result in giving to the peripheries of the rolls a speed greater than is usually obtained by the large diameter of the common rolls. Such arrangement, together with the use of sufiioient animal power, of which there is not commonly any lack, insures the efficiency and dispatch, which is of such primary importance in this connection.

It will be seen that every roll is driven equally and directly from the master-wheel, instead of from the pinion of one roll to that of the next, and so on through the series.

It will also be seen that the master-Wheelin respect to its interior as well as its exterior cogs-meshes with the pinions I, I I, I I I, of the rolls at points immediately in line with the work or place of greatest stress of the cane on the peripheries of the rolls. This arrangement enables the construction of a mill of any given capacity at much less than the usual weight and cost, and of much greater compactness. It also insures a greater freedom from strain and oblique bearing, and consequently a more perfect transmission of the power. It also enables the rolls 2 and 3 to be placed so near together as to dispense wholly, or nearly so, with a return-plate.

I claim herein as new and of 1nyinvention The arrangement ofthe doublycogged master-wheel E, meshing with the disconnected pinions I, I I, I I I, coincident with the lines of contact of aseries of crushing` or other rolls, l 2 3, the whole being combined and operating together in the manner and for the objects stated.

In testimony of which invention I hereunto set my hand.
