IMPROVEMENT IN MILLS FOR GRINDING TORTILLA, GREEN CORN, &c.
Specification forming part of Letters Patent N0. 220,525, dated October 14, 1879 application led August 20, 1879. n Y
To all whom it may concern.-
Be it known that I, FREDERICK A. GARD- NER, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Mills for Grinding Tortilla, Green Corn, or other similar material, which improvements are fully set fort-h in the following specification and accompanying drawings, in whichi Figure 1 is a vertical section through a por- ;tion of the mill, showing the grinding-cone, the. means for adjusting it, and the feeding mechanism; also, the base attached to a table, bench, or other horizontal support. Fig. 2 represents a back view with the removable portion of the hopper taken' off Fig. 3, a side elevation ofthe lower portionof the mill, showing the base attached to a vertical support or wall; and Fig. 4 represents a plan`or top view of upper part of the mill.
" is provided with projecting pieces B, to embrace the shaft Bl of the feeding device-B2, so as to hold it and allow it to turn when both parts are in place, as shown in Figs. l and 4.
' The removal of the part A releases the feeding mechanism B1 B2 and grinding-cone shaft C. The cone G1 and shaft Bl are geared together at G2 C3, so that the gearing is inside of the mill, as shown. The grinding-cone Ol is arranged to turn easily on the shaft C, and
is connected with the handle D, so as to turn with it, and be easily detached when necessary. It is kept' in place by a spring, D1, and thumbnut and screw D2, the arrangement being such that the cone will yield as the material is forced through it by the spirally-arranged wings or blades B2 of the feeding device and the operation of grinding.
E represents a thumb-nut and screw for connectingthc mill to the base El. That portion of the base to which the mill is attached is formed at an angle, E2, and the lower part or foot, I, of the mill is made to correspond, so that it may be connected to a horizontal support, as in Fig. 1, or to a vertical support, as in Fig. 3, so that the mill can be used in either position, as shown.
The material to be ground being soft, the gearing Cz O3 is not obstructed by it, but assists in the grinding., F is a mouth or lip over which the material passes as it leaves the mill, and H represents a spring-scraper. G is the case or concave for the grinding-cone.
I claim as my inventionl. The concave G and grinding-cone Ol, having a suitable handle for operating it, and provided with the gearing C2 at the smaller end., as shown, in combination with the shaft B1, arranged Within the hopper and provided with the gearing O3 and two or more spirally-arranged Win gs, B2, for the purposes described.
2. The hopper consisting of the removable parts A and A1, each provided with the holdin g-pieces B, adapted to form bearings for the shaft B1, in combination with the shaft O and thumb-nut and screw A2, for holding the several parts together, substantially as specified.
