MILL.

SPEGIFICATION forming part of Letters Patent No. 250,141, dated November 29, 1881.

Application filed April 11, 1881. (No model.)

To all whom it may concern Be it known that we, JAMES A. FIELD and ALEXANDER IVIAGEE, of St. Louis, Missouri, havejointly made a new and useful Improvement in Cane-Mills, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, makingpart of this specification, in which- Figure 1 is an end elevation of a cane-mill having the improvement; Fig. 2, a vertical transverse section, and Fig. 3, a vertical longitudinal section, partly in elevation, of the mill Figs. 4 and 5, respectively, an end and a side elevation of the guard between the feed and the delivery roll; Fig. 6, adetail, being an elevation, showing the upright at the end of the mill opposite to that end shown in Fig. 1, and the spring and spring-holder used in holding the guard against the feed-roll; Fig. 7, a detail, showing an end of the guard and the adjacent portion of the upright; and Fig. 8, a section taken on the line 9 g, Fig. 1, through the plate that incloses the guard.

The same letters denote the same parts.

The present improvement relates partly to the guard used in upholding the stalks between the feed and discharging rolls, and the means for holding the guard against the feedroll.

In the annexed drawings, A represents a cane-mill embodying the present improvement, and, saving which, ofthe usual form, having the crusher-roll B, feed-r0110, and delivery-roll D. The rolls are journaled in the uprights E E, which are united by the cross-plates F F, the plate F having the benringf. A bevel-gear, G, turning upon the bearing], engages with the gear H upon the crusher-roll shaft b. A gear, I, upon the shalt b, and within the upright E, engages with thepinions Jand-K, respectively, upon the feed-roll shaft 0 and the delivery-roll shaft (1, and by attaching a sweep to the uprights (but the lower ends, gg, of one shown) the mill can be operated.

Between the feed and delivery rolls is the guard L, the peculiar shape of which is shown more distinctly in Figs. 2, 4, and 5. It performs the usual office of upholding the cane after it has passed the feed-roll, and preventing it from falling into the juice, which is collected in the pan M. The guard occupies the principal portion of the space between the feed and delivery rolls, and its edge I is kept as closely as is practicable to the surface of the feed-roll. As the latter in use has a slight movement (owing to the varyingthickness of the layer of cane being crushed) toward and from the crusher-roll, provision is made for accommodating the edge lofthe guard to the varying position of the feed-roll. To this end the guard is provided with journals 1 l, which turn in elongated bearings l and which are preferably in the uprights E E, as shown in Figs. 1, 6,7, and with projections 1 against which springs l l press, the springs being held in holders 6 e, which are attached to or made part of the uprights. The springs are preferably ofrubber,and their onterends press against the projections l l (which are suitably flattened to form bearings for the springs) and tilt the guard on its bearings against the feedroll, and following thelatter in its movements toward and from the crusher-roll. The guard is held in the uprights by means of the plate I", which is passed over the projection 1 and fastened to the upright E by means of thelug e and screw 6 I The box P, as well as the boxes N O, can be easily removed, when desired; and by removing the plate I the guard L can at once be withdrawn from its position, and the space between the rolls and the interior of the mill readily washed and cleaned.

I claiml. The combination of the guard L, having the journals 1 l and projections l Z the springs l l and the feed-roll U, substantially as described.

2. The combination ofthe crusher-rollB, the feed-roll O, the delivery-roll D, and the guard L, having thejournals l l, and the springs l 1 hearing against the projections l Z substantially as described.

3. The combination, in a cane-mill, of the'uprights EE, the guard L, and the removable plate Z, substantially as described.
