EDVIN H. P EASE, OF RACINE, VISCONSIN.
FANNING-MILL.
SPECIFICATION forming part of Letters Patent No. 312,157, dated February l0, 1885.
Application filed November 12, i884.
To @ZZ whom it may concern:
Be it known that I, EDWIN H. PHASE, a citizen of the United States, residing at Racine, in the county of Racine and State of iVisconsin, haveinvented certain new and useful Improvementsin Fanning-Mills; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to the style of fan-ningmills organized in such a manner as to effect a preliminary separation of the dust and chaff from the wheat before it is subjected to the riddles and the usual fan-blast.
The object of my invention i's to furnish a fanning-mill in which this preliminary separation of the dust and chaiil is effect-cd solely by the action of a suction-fan.
To this end my improvement consists of certain combinations, which are f specifically pointed out in the claims, and the embodiment of which I will proceed to set forth in the ensuing detailed description.
Figure lis aside elevation of a fanning-mill embodying my improvement. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a plan view of the same, the feed-slide of the hopper being omitted to show the. dusttrunk. Fig. -i is a perspective View of portions of the fanning-mill, illustrating` more particularly the dust-tru nk.
The same letters of reference indicate identical parts in all the ligures.
The side boards A of the farming-mill are constructed at the front end with the usual casing, A, which contains the blast-fan B. The end shakingshoe, composed ofthe side boards D and screens or riddles C, is supported at each side by a pair of springs, E E. the lower ends of the springs being secured to the side boards A and the upper ends to the side boards D of the shoe. The shoe is reciprocated endwise by a pair of eccentrics, F F, and the eccentric-rods F F', the eccentrics being secured to the shaft B of the blast-fan B. An inclined cross-hoard, D, of the shoe forms the bottom of the hopper G, constructed with the ordinary slide, G, for regulating the feed.
The construction of the farming-mill described so far does not differ substantially from (No model.)
other known fanning-mills. lVith these parts I combine a suction-fan, H, the case H of which is mounted above the vcasing A of the blast-fan B, and is provided with an air-port, h, at each side. The air-ports h open into the dust-trunk I, a iiat chamber, which extends -from the suction-fan to the frontend of the shoe` reaching to a point above the crossboard d of the shoe, as clearly shown in Figs. 2 and 4. rI he dust-trunk Iis made flaring,- as shown, so that its mouth is about -as wide as the riddles. A detlector, i, is erected on the dust-trunk just in front of the shoe, so that the grain falling from the hopper-bottom may iind no lodgrnent on top ofthe dust-trunk, but be caused to fall to the riddles below the mouth of said trunk. As the grain passes the mouth of the d ust-trunk it is subjected to a strong d raft, 7c
by which the dust and chaff' mingled with the grain are separated there from and drawn into the suction-fan, from which they are discharged through the discharge-spouth. The draft of the fan may be somewhat tempered by a valve, K, suspended over the riddles in front of the mouth ofthe dust-trunk I, the stein of the valve being combined with a ratchet and pawl, K, for the purpose of adjusting it. The draft-ports h of the suction-fan are provided with slides or valves if, so that they can be opened more or lessto govern the drafts.
I am aware that tanning-mills are known in which a preliminary separation of dust and chaff is effected` and in which even a suctionfan is used to aid iu the separation, as shown in United States Patent No. 267,699.
I am also aware that farming-mills are known in which the grain falling` from the hopper is subjected to a draft created by the same suction-fan that acts supplementary to the riddles in the final separation.
I am also aware that an independent suctionfan has been combined with riddles anda blastfan to create a strong current th rough aportion of the riddles and take off the chaff and light material.
llIy invention is distinguished from these k nown structures or combinations by the relative arrangement of the parts, as set forth in the claims, whereby superior results are obtained.
I claim as my invention- 1. The com bination, substantially as before set forth, of the hopper, the shaking sieves or riddles below'the hopper, the blast-fan, the independent suction-fan, the suction or dust trunk, which is arranged, substantially as described, so that the grain falling from the hopper-bottoni to the riddles passes acrossthe mouth ofsaid trunk, and is there subjected to a cross-draft, and the delector on the dust trunk in front of the riddles.
2. The combination,v substantially as before set forth, of the hopper, the shaking sieves or riddles below the hopper, the blast-fan, and the independent suction-fan, with the dust-- trunk having the deector fr' in front of the riddles, and having its mouth reaching to and i 5 communicating with the space directly between the hopper-bottom and the riddles, a valve, K, suspended over the riddles and in front of the mouth of the dust-tru11k,andsuit able means for adjusting the valve.
In testimony whereof I affix my signature in presence of two Witnesses.
EDVIN H, PEASE.
