PROVISIONAL SPECIFICATION left by the said Henry Cutler at the Office of
the Commissioners of Patents on the 28th September 1878.
HENRY CUTLER, of No. 59, High Street, Borough, Southwark, in the County of
Surrey, Seed Factor. "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
DRESSING GRAIN, RICE, AND SEEDS."
According to my Invention the sieves for dressing the grain, rice, or seeds are
supported at one end by pivots or joints having reciprocating motion of-which the
sieves partake, and at the other end the sieves are supported by elastic suspenders.
In conjunction with the sieves so arranged I provide strikers whereby a downward
and upward shaking or jumping movement is given to the sieves in addition to their
reciprocating motion already mentioned.

HENRY CUTLER, late of No. 59, High Street, Borough, Southwark, in the
County of Surrey, and now of No. 13, Southwark Street, in the same County,
Seed Factor. "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DRESSING GRAIN,
RICE, AND SEEDS."
According to my Invention the sieves for dressing the grain, rice, or seeds are
supported at one end by pivots or joints having reciprocating motion of which
the sieves partake and at the other end the sieves are supported by elastic
suspenders.
In conjunction with the sieves so arranged I provide strikers so as to give a
downward and upward shaking or vibratory movement to the sieves in addition to
their reciprocating motion already mentioned.
Fig. 1 of the accompanying Drawings shews in side elevation a machine em-
bodying my improvements; Fig. 2 is an end elevation of the machine; Fig. 3 is

a longitudinal vertical section of the same; and Fig. 4 is a plan thereof.
framework of the machine; 2 is the fan or blower; 3, its shaft; 4 and 5 are the sieves ;
6 and 7 are pivots or axes provided with antifriction rollers 8 and 9 working in
guides 10 and 11 for supporting the sieves at one end and allowing of their recip-
rocating motion. The other ends of the sieves are supported by elastic suspenders
12; 13. In the arrangement illustrated the parts 12 and 13 are of india-rubber like.
door springs (secured by hooks 14, 15, to the sieves); and the parts 12*, 13*, are of
chain having their upper ends suitalby secured and passed around shafts 16, 17,
provided with hand wheels 18, 19, for the purpose of adjustment.
The turning of the shafts 16, 17, by the chains is prevented by toothed or ratchet
wheels 20, 21, and pawls 22 and 23.
24, 25, are the strikers whereby downward movement is given to the sieves,
whose return or upward movement is produced by the elastic suspenders. The
strikers consist of levers having their fulcra at 27 and provided in the present case
with india-rubber rollers or tubes 28 able to turn on the lever ends, so as (to
prevent undue wear) not always to strike with the same parts of their surfaces.
The reciprocating motion is given to the sieves and up-and-down motion to the
strikers in the present instance as follows:-
Upon the ends of the shaft 3 are fixed grooved or slotted crank discs 29, 30,
connected slotted arins 31, 32, (working on the axis 27) by means of adjustable
connecting rods 34, 35. The crank pins are adjustable in the grooves of the crank
discs 29, 30, for altering the lengths of stroke of the slotted arms, equidistant circles
being marked on each of the crank discs, so that the pins may be easily set to agree
with one another on each side of the machine. The slotted arms are also equally
divided so that the connecting rod pins may be likewise set to agree in each for
altering the angle of the arms 31, 32, and consequently giving a more or less down-
ward and upward movement to either of the sieves. Upon the shaft 3 is also fixed
a pinion 36 driven by a spur wheel 37 having a handle 38 which drives the fan or
blower 2, and also produces the reciprocating and vibratory motion to the sieves by
the action of the strikers. The reciprocating motion of the sieves is produced by
rods 39, 39*, connecting the pivots 6 and 7 with the slotted arms 31 and 32.
The strikers 24, 25, are connected at 26 to the slotted arms 31, 32, or they may be
made in one with the arms.
The striker ends as they descend come in contact with the projecting ends of
rods or bars fixed to the sieves and provided with elastic rollers or tubes like those
on the striker ends. The blows thus given cause the ends of the sieves to descend
rapidly and they are rapidly returned by the action of the elastic suspenders; thus
constant up-and-down movement or vibration given to the sieves so as to keep the

page_text: contents in constant motion besides the longitudinal to-and-fro reciprocating motion
given through the connecting rods 39, 39×, the rods 39* being connected to the
upper sieve's pivot, and the rods 39 to the lower sieve's pivot.
Having described the nature of my said Invention, and explained in what manner
the same is to be or may be performed or carried into practical effect, I would have it
understood, that what I consider to be novel and original, and therefore claim
as the Invention secured to me under the Letters Patent herein-before in part
recited is,
1. The method, substantially as described, of imparting a downward and upward
shaking or vibratory movement to the sieves and their contents in grain, rice, and
seed dressing machines.
2. The arranging machinery or apparatus for dressing grain, rice, and seeds, so as
to give the sieves a combined vibratory and reciprocating movement, substantially
as described with reference to the accompanying Drawings.
In witness whereof, I, the said Henry Cutler, have hereunto set my hand
and seal, this Twenty-seventh day of March, in the year of our Lord One
thousand eight hundred and seventy-nine.
HENRY CUTLER. (L.S.)
