Description

Vif" MMU waited 'tang Letters Patent No. 104,004, dated .func 7 l IMPROVEMN T INUTAILING-ELEVATORS FOR SEPARATORSI.

The Schedule 'referred to in these Lettere Patent and malring'part o the same.

To all 'whom it may concern:

Be it known thatlgnrnon B. FARQUHAR, of York, in the county of York and Stateoi Pennsylvania, have invented new and useful Improvements in .Tailing-Elevatois for con. .u ,5 material known as tailings from the fan back to the thrasher of a graiuseparator; and I do. hereby declare that the fol- 4lowing is a full, clear, audeiact description of the "construction and operation oi the same, reference being had to the annexed drawings making part of this specification, in fWhichl-- i ,Figures I and 3 are a top viei'v or plan, and

Figure 2, a vertical section. My improvements. are divided i into vseveral parts, which may be used separately or in connection, and

which' niay be applied vto maohineslmfWsimilar class heretofore in use. v

The nature and novelty of myinvention consists inthe arrangementoi'a helixV (or suhall'screw) in a trough or pipe, for. conveying the Whitecaps and uuthrashed heads of grain (technically styled tailings) from the fanback to the thrasher of a grain-separator, and., by means of a screen in bottom-of said trough, separating therefrom the cookle and dirt.

To enable others vskilled in the art to make and use mynvention, I will proceed todeseribe its construction and operation.

T elevating-trough A H 4rests at one end near the' an, the other being,r raised suciently to discharge through spout D into the thrasher.

y The tailings may be delivered from the fan into the elevator in the mslm-1 manner by a shaking spout, but this arrangement being very temporary and liable to `choke in Wet grain, I prefer using; another trough and helix, as shown in iig. 3, opening into the elevator at right angles, thus obviating the possibility of choking. The helices are readily formed by winding half-inch round'or square iron over a revolving mandrel in -an ordinary enginedathe, allowing one .end to extend out far enough to receive the-flliving-pulley C.

The power required to operate it is scarcely appl-e eiable. The tailings are carried up inside of the coil, and are discharged evenly into the thrasher. Most of the cockie, chess, and other impurities pass through the screen F into a box below, the'screen being-kept clear and open bythe revolving helix or screw rubbing over it'.-

Nine out of every ten grain-separators in use are provided with tolling-elevators made of a series oi' buckets o1: blocks fastened to revolving belt, and

they are the most troublesome part of the machine,

from liability to get ont oi' order and choke up.

N ow, it will be readily seen that these objections are -entirely'overoome by my improvement, since the iron coil will last a lifetime, and cannot get out of order or choke up, besides costing less than halt' vas much to make as the old style.

I may add, in conclusion, that I have thoroughly tested its operations during the pastseasonv upon a number of machines, and the universal testimony oi experienced thrashers encourages me to present my claims for what I deem as novel as they have been proved useful.

i I do not claim the several parts.herein shown, nor

any general combination of the. same; but4 Nhat I do olaimis- The arrangement of' the trough A and helix -15 with trough H, helix B, screen F, and spout I), as herein described and for the purposes set forth.

` ARTHUR Il. FARQUHAR'.
