PROVISIONAL SPECIFICATION.
An Improved Apparatus suitable for Working Machines such as
Chaff Cutters, Root Pulpers, Grinding Mills, and the like.
I CHARLES HAMMOND Apple Tree Cottage Pilgrims Hatch South Weald
Essex Market Gardener do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a simple and effective means whereby
the labour of operating machines such as chaff cutters, root pulpers, grinding
mills, and the like, may be reduced to a minimum and allowing the operator to
maintain an upright position, also affording an opportunity for the application of
any number of operators at the same time.
According to this invention I provide a lever (either straight or curved) which
may be suspended from a suitable support being part of a building preferably at
right angles to the crank or driving wheel of the machine to be operated and
connected therewith by means of connecting rod and clip and free to swing in a
backwards and forwards direction. This may be of any length and may be made
of any suitable material or materials.
By a simple backwards and forwards pressure of the lever by the operator the
crank or driving wheel is actuated.
In cases where it is difficult or inconvenient to suspend the lever I simply
invert it.
For heavy work I provide a second lever which may be hinged to the floor of
a building and free to move in a backwards and forwards direction. This lever is
connected to the first lever by means of a link or links and is intended to increase
the pressure of the operator.
When this attachment is connected to the driving wheel of a machine the
balance of the wheel may be disturbed, in which cases I use a weight placed on
the driving wheel of the machine in such a manner as to produce an even balance,
or, I may lengthen the connecting rod beyond its point of junction with the lever
and place the weight there to effect the same purpose, and in that case I place the
two levers further apart to avoid fouling.
I also provide cross handles which may be used with either of the levers and
are removeable and adjustable and may be of any length according to the number
of operators to be accomodated.

COMPLETE SPECIFICATION.
An Improved Apparatus suitable for Working Machines such as
Chaff Cutters, Root Pulpers, Grinding Mills, and the like.
I, CHARLES HAMMOND of Apple Tree Cottage, Pilgrims Hatch, South Weald,
Essex, Market Gardener, 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 my invention is to provide a simple and effective means whereby

page_text: the labour hitherto absorbed in operating chaff-cutters, root-pulpers, coffee, paint,
cement, and other grinding mills, and like machines, may be considerably reduced,
and which also permits the operator to maintain an upright position, and affords
means by which two or more persons may operate the manipulation of one machine,
a desideratum where machines are needed or desirable of greater capacity than
can be operated by one person, and space and other considerations preclude the
use of steam. borse or other than manual labour.
My invention consists of a suitable arrangement of levers, the primary or first
of which is suspended or otherwise mounted in a vertical position, and provided
with an interchangable cross bar by which the same may be oscillated by one or
more persons, such oscillatory motion, being, by the aid of suitable connecting
rods, converted into rotary semi-rotary or other motion, and which may be employed
for manipulating either or any of the machines named or others analageous
thereto.
In order that the principle of my invention, and the means by which I prefer to
carry the same into effect may be more easily understood, I have hereunto
appended a sheet of drawings, in which I have chosen to illustrate its application
to, and in connection with, a chaff cutting machine, Fig. 1 being a side elevation,
while Fig. 2 is an elevation of the first or primary lever (where a compound
leverage is employed) as this would appear if viewed from the right to the left of
Fig. 1.
For the purposes of my invention I provide of any suitable material, and of
any desired length, a lever such as A, which may be either straight or curved as
occasion may require, and which, for preferance, I suspend at a point B to a
bracket or other contrivance C. fixed to any convenient part of a building, such
for instance as a beam D, and preferably in such a position that this may oscillate
in a direction at right angles to the crank or other shaft of the machine it is
intended to operate, which, as previously stated, is assumed to be a chaff cutting
machine E, having a fly-wheel F, with spokes or arms G carrying the cutting
knives H, to one of which said arms, in the usual way, would be connected a
suitable handle at or about the point J, and to this point I pivotally connect one
end of a metallic or other rod K, the opposite end of which is connected by a pin
or bolt to any one of several holes a provided in the lower end of the lever A,
these being for attaining a greater or lesser leverage as required, the said rod K
being of any desired length, and preferably curved outwardly at the point b to
afford a clearance for, and so as not to foul with, the nut or nuts c upon the axle
of the machine. The lever A. is provided with other holes d for the reception of
a handle L, by means of which a labourer may whilst standing almost ere :t
oscillate the lever A within the angle shewn by dotted lines, and so impirt rotary
motion to the wheel F in the direction of the arrow Fig. 1, or if desired, a rod or
pole may be employed in lieu of the handle L, as suggested at M Fig. 2, so that
two or more persons may be employed to oscillate A if desired or needed. In
cases where it may be difficult or inconvenient to suspend the lever A as shewu,
I may invert this and connect the same end to a like bracket, or other pint B,
upon the floor or ground.
For heavy work, or such other machines as may entail more labour in their
manipulation, I provide a second vertical lever N, hinged or otherwise pivotally
connected at a point to a bifurcated or other bracket such as O, or any suitable
equivalent therefor, fixed upon the floor of a building or upon the ground. The said
lever N may be provided with a number of holes such as for the reception of a pin or
pins for pivotally connecting thereto one end or ends of a link or links P, the
opposite end or en is of which is or are connected in like manner to the lever A,
the upper end of N being provided with an eye for the reception of a rol or pole
such as M of any desired length, so that two or more persons, standing at the same
or opposite sides, may operate the oscillation of N, and consequently A for the
rotation of F which affords an increase of pressure and power to the operators.
In order to reduce friction as much as possible I may introduce at any of the

page_text: points of the movable connections between one part and another suitable rollers,
wheels, or balls as bearings, and in cases where the balance of a driving wheel of
a machine is disturbed by such connections I may place a weight upon any
suitable part of such wheel to overcome dead centres, or I may extend the length
of the rod K, beyond the point of its connection with the lever A, and place a
weight thereon to effect the same purpose, in which case I may find it convenient
to place A and N further apart to avoid fouling, and employ a longer link P.
In connection with such machines or such or other machines having motion
other than rotary, I may find it convenient to employ only a part of the said
combination of levers, rods, or links, or the same combination otherwise arranged,
or employed for imparting motion to one part of a machine, that may impart like
or other motion to another part or another machine, and I reserve to myself the
right to connect, combine, and operate the said levers, links, or rods, or any
portion of them, in any desired manner, to attain the same or like results without
departing from the principle involved.
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 :-
1st. In an improved means for imparting motion to rotary and other machines
by manual labour, the herein described method of utilizing, oscillating levers, and
connecting rods and links, and any desired combination of the same substantially
as set forth and shewn.
2nd. For an improved apparatus for imparting motion to rotary and other
machines, such as chaff-cutters, root-pulpers, grinding-mills and the like, the
combination of a depending or otherwise pivotted lever, such as A, connected by
a rod such as K, to a wheel or its equivalent such as F mounted upon the main
spindle or shaft of the machine, with ineans such as a handle L, or rod M for
imparting an oscillatory motion to the said lever A, and rotary or other motion
to the said wheel, or a lever such as N carrying a rod such as M, and connected
to A by a link P, substantially as herein described and shewn.
