Improvements in Agitators.
I NATHAN LEES HILTON of 147 Back Lane Hyde in the County of Chester,
General Dealer do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The object of this invention is to construct a simple and convenient apparatus for
the mixing together and agitating of chemical or other compounds of a similar nature
such as malt or grain with water or liquor during the process of brewing, distilling or
otherwise; hat bodies during the process of dyeing, washing out or staining; paper
or other pulps, soap, size, proof, grease colors, or for any other similar purpose to which
an agitator is or may be applied.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the drawings hereunto annexed and the following explanation thereof. Fig. 1. is a
sectional elevation of my improved apparatus which consists chiefly of the tank or
vat a (or a kettle or other suitable vessel) to which is attached the frame b for
supporting the vertical spindle c and the reversing gear hereinafter described.
The vessel or vat a may be constructed of wood metal or earthenware or other
material according to the purpose for which it is intended, and if required it may be
heated by means of coal, gas, oil or other fuel which can be used in a furnace beneath
the vessel or by a steam pipe or coil of piping inside the same, or by means of a steam
jacket or otherwise.
The vertical shaft c may be supported entirely from above, as shown on the drawing
or it may, if preferred, be carried downwards and work in a footstep at the bottom of
the vessel.
Near the top of this vertical shaft c outside the top of the vessel a is fixed a bevil
wheel e gearing with a similar wheel f keyed upon the horizontal shaft g which is
also supported in suitable bearings and is connected by toothed gearing with a shaft h,
provided with three pulleys i, j, k.
The pulley is fast on the shaft h and the two other pulleys jand k are loose.

page_text: At one end of the shaft h is a worm (see also detached end view Fig. 2) actuating
a worm wheel on the face of which is a stud m acting against the weighted lever n
the lower end of which works between two pins fixed in the sliding bar o which
carries the strap fork p. The pulley i has cast to it a spur pinion q which drives the
shaft g through a carrier wheel r, and the pulley k has cast to it a similar pinion s
which drives the shaft g through a single wheels, therefore if the driving strap is on
one pulley it will drive the shaft g and agitator in one direction, and if it be placed on
the other it will drive the same in the reverse direction.
The shifting of the driving strap from one to the other is effected by the action of
the pin or stud m against the weighted lever n, and thus the shaft will be driven a
few turns alternately in each direction.
The same alternating effect may be produced by having three pulleys (one fast between
two loose or vice versa) and having two straps (one plain and the other crossed) and by
shifting the two straps sideways together, each one in its turn becomes the driving
strap and drives the shaft either forwards or backwards (according as the plain or
crossed strap becomes the driver) whilst the other strap runs free, on the loose
pulley.
On the vertical shaft e below the frame b I fix a boss t having two or more arms u
projecting therefrom horizontally; and fixed therein are rods or arms » projecting
downwards towards the bottom of the vessel (see also partial longitudinal section
Fig. 3).
These latter on the shaft c being caused to revolve will act as stirrers or agitators
and keep the contents of the vessel in constant agitation.
I do not bind myself to the number or shape of the stirrers nor to the material of
which they may be made.
Having now particularly described and ascertained. the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is, the improved agitator constructed and operating substantially as and for the
purposes hereinbefore described and illustrated by the drawings annexed.
