DEVI BRONSON, OE BUFFALQ, NEWYORK, ASSIGNOR T0 JAMES BRALEY,
y 0F SAMEl PLACE.
Letters Patent No. 110,196, dated December 20, 1870 i lMPRovsMENTm FANenne-MILLS.
The Scheduln referred to in these Letters Patent and making part o! the sume.
I, LEVI BRO-uson', of Buffalo, in the' county of Erie, and State of New York, have invented certain new and useful Improvements in Fanning-Mills,of which the following is a specification.
Nature of thelf'iwnton.'
shoe, as hereinafter described;
General. Description.
Figure 1 is a sectional side elevation.
Figure 2 is a perspective view of the bottom of the Fjgure 3 is a perspective ofthe half shaftand head.
A is the ordinary shoe, except that it is stationary instead of movable, as is usual. Inside of this I arrange another shoe, B, to which is attached the sieve or sieves z, and give it a longitudinal, vibrating, and also an npanddown movement.
This is accomplished by means of the half shaft O having a pulley, a on its outer end, and an adjustable head, D on its inner end, which is provided with holes b b', set at unequal distances from the center, through which a wrist-pin, c, is set, having attached a spring arm or pitman, E, the other end being fastened back to the lbottom of the movable shoe B.
This gives it the forwardandbackward or vibrating movement, which 'is regulated by means of the adjustable head, as abovedescribed.
To produce the up-and-dow'n movement, a bent rod or'hauger, d, is hung by both ends to the front end of outside flame A, and runs across and underneath the shoe B, the bottom of the shoe near' its end resting on the hanger.
` As the shoe is moved forwardand backward, this hanger which sways with\ it, moves the shoe up and downwhen carried beyond the perpendicular.
To produce a higher movement, the hanger is set back a short" distance on the bottom of the shoe, in. slot e, provided for it.
To get less of this tossing m otion, it is set in slot e. toward its outer end, (see fig. 2.) By this method of adjustment I claim that my fanning-mill will discharge more freely than others.
E' is the ordinary 'screw-conveyer.
Instead of attaching fingers to the grain-board f, I attach ngers g g to the feeding end of the inside Shoe, and which,'theretbre, receive the double motion of the shoe, and thereby distribute better than stationary gers attached in the usual manner.
My grain-board f is stationary, being attached to the outer shoe, as shown in g. 1.
Screens are ordinarily attached to the shoe in a loose manner, by pins orlugs, but soon wear loose and have to be repaired; but I attach mine by means of bolts orvtheir equivalents, as shown in figs. 1 and 2. The special advantages of my construction are, 'lhe shoe is less liable to clog; also, by means of the adj nstable head and pitman,a long or short stroke,
for different kinds of-grain, is obtained, which is highly important.
lhe adjustment of the shoe for the up-and-downv motion is also important, as it allows the screens to clear themselves with much less blast than by the old method.
I am aware that shoes are often hung to vibrate forward and backand up and down, but notlike mine, 0r moved by my means. .I am acquainted with a patent of M. Laufenburge, June 2, 1860, which shows two inclined sieves vibrating alternately, but mine do not vibrate alternately, but both have thc same motion and are 'attached to lthe shoe B.
.lhe novelty in my invention consists of the inner shoe B, with spring arm or ptman E, with the head D, having adjustable holes b b' for the wrist-pin c, by which a forward-and-backward movement is obtained; also, in the adjusting of the hanger d on the .bottom of the shoe B' by meaof slots e c', or their equivalents, which gives a greater` or lesser tossing motion to the shoe also, att-aching the fingers g g to the inner shoe, by which they .receive a .double motion, and thereby distribute better.
Olm/ms. l
1. '.lhc arrangement ofthe spring E with the inner shoe B, hanger d, and slots e e', when constructed substantialy as shown and described.
2. The skeleton head D, upon short shaft C, provided with the adj nsting hol'es b b', combined with'the inner shoe B, constructed substantially as set forth.
3. The combination and arrangement of the inner shoe B, screw-conveyer F, bent ngers g g, attached to the head of the inner shoe. the whole constructed substantially as and for the purpose described.
In witness whereof I have hereunto signed my 'name in the presence of two subscribing witnesses.
