Combined thrashing and winnowing machine.
PATENT COMBINED THRASHING MACHINE for preparing all kinds of grain for market in one operation.
This machine will thrash every description of grain completely, separating the corn, straw, caving, and chaff from one another, delivering them in the places assigned to each. The drum beaters are less liable to split the corn than any other kind, perfectly cleaning the straw no matter what its condition may be.
The straw shakers possess all the advantages resulting from the use of 2 cranks; one only being used, the amount of tossing of the straw can be regulated a3 circumstances dictate. The short straws (or caving) are separated from the corn and chaff by the vibrating riddles. The winnowing apparatus is fitted with one fan and suitable screens for dividing the corn from the chaff, and conducting the former to the patent corn elevator to be elevated into the separating screen.
This machine is 3 ft. 4 in. wide, and can be driven with either a 3 or 4-horse power engine. It does its work equally well with the larger machines (requiring 8-horse power engines to work them), preparing the corn in one operation fit for market. In the construction of it none but the very best materials and workmanship have been employed, complication of working parts have been reduced to the smallest minimum, economising the expense in repairs, reducing friction, and consequently the power required to work it. The revolving separating screen is placed immediately across the machine, behind the drum, the several samples of corn on leaving it are conducted to either side of the machine, by suitable spouts, into the sacks placed to receive them. This arrangement removes the large projecting box in which the separating screen is usually placed from the side of the machine, not only giving it a neater appearance, but preventing all accidents to the same when being removed from place to place. The separating screen is novel in construction: its form is conical, the object being that as the corn passes down it, its diameter increasing, the amount of screening surface the corn has to pass over becomes greater.
In itself it is of the strongest form, the longitudinal bars are drilled, giving the required distances of the wires encircling it, and which wires are passed through these holes instead of being bound on the outside, as usually the case • from this it is obvious the mesh of the screen cannot be altered by the encircling wires shifting on the longitudinal bars. The bearings (which are supplied with lubricators) are almost all external, and so open the internal parts of the machine to view.
These small machines will be found of great advantage to persons whose extent of occupation precludes their employing engines of greater power than 4 horse, yet the same results are obtained, and the engine can be used for driving mill-stones, bruising mills, chaff cutters, and other barn machinery.

The advantages of the corn elevator in this machine, are:—
1. It elevates any description of grain in any quantity, without the use of the ordinary tins.
2. It dispenses with the second blower, as the core is dressed in its passage to the separating screen, from which it is delivered in different samples fit for the consumer.
3. It greatly simplifies the machine, inasmuch as the barley, homer, 2 fans, 2 sets of elevators, tins, 6 straps, and 17 pulleys are dispensed with, thereby economising wear and tear to a considerable amount.
