PROVISIONAL SPECIFICATION.
Improvements in Stacking-machines or Elevators.
I, ROBERT MAYNARD, of Whittlesford Works, near Cambridge, Engineer and
Iron and Brass Founder, do hereby declare the nature of this invention to be as
follows:-
This invention relates more particularly to an improved construction and
arrangement of the frames of stacker or elevator machines and has for its object
to increase the utility and efficiency of such machines by rendering the frames
thereof more durable and substantial and imparting more perfect equilibrium
thereto.
To carry out my invention I fit the back of the frame of a stacker or elevator
with two auxiliary angular extensions or limbs placed one on each side of the
frame. These limbs resemble in their general outline and form a grasshopper's
leg, while the bend or knee of each limb forms a support for the trough of the
machine, which takes a bearing thereon and thus has additional firmness and
security imparted thereto. The object of making the auxiliary limbs in this form
is to allow room for a horse when working the machine to pass under the frame-
work thereof without obstruction and without impeding the working of the machine.
The lower ends of the auxiliary limbs are connected in any convenient manner to
the hind wheels of the machine. A further improvement consists in so fitting and
arranging the spindle which forms the axis of the horse wheel that it serves both
as the pin whereon the front wheels of the machine lock round and as a bearing
to assist in carrying the weight of the trough.
By my improved construction of the frames of stacker or elevator machines
such machines are enabled to be more easily and conveniently worked at the same
time that greater strength and security are imparted thereto.

COMPLETE SPECIFICATION.
Improvements in Stacking-machines or Elevators.
I, ROBERT MAYNARD, of Whittlesford Works, near Cambridge, Engineer and
Iron and Brass Founder, 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 :-
.
This invention relates more particularly to an improved construction and
arrangement of the frames of stacker or elevator machines and has for its object
to increase the utility and efficiency of such machines by rendering the frames
thereof more durable and substantial and imparting more perfect equilibrium
thereto.
To carry out my invention I fit the back of the frame of a stacker or elevator
with two auxiliary angular extensions or limbs placed one on each side of the frame.
These limbs resemble in their general outline and form a grasshopper's leg and are
hereafter referred to as grasshopper limbs. The bend or knee of each limb forms
a support for the trough of the machine which takes a bearing thereon and thus
has additional firmness and security imparted thereto. The object of making the
auxiliary limbs in this form is to allow room for a horse to pass under the frame-
work without obstruction when working the machine thus preventing the impeding

page_text: of such working. The lower ends of the auxiliary limbs are connected in any
convenient manner to the hind wheels of the machine. A further improvement
consists in so fitting and arranging the spindle which forms the axis of the horse
wheel that it serves both as the pin whereon the front wheels of the machine lock
round and as a bearing to assist in carrying the weight of the trough.
By my improved construction of the frames of stacker or elevator machines such
machines are enabled to be more easily and conveniently worked at the same time
that greater strength and security are imparted thereto.
In the accompanying drawings
Fig. 1 shews a view in side elevation of a stacking machine or elevator con-
structed according to my invention and
Fig. 2 shews a plan view of the carriage of such machine.
A is the frame having attached thereto one of the grasshopper limbs B above
described the members whereof are secured by plates B¹ under which the horse
passes at C a corresponding limb being attached to the frame on the other side.
Such limbs B serve to support the trough D which is jointed at E in the ordinary
manner to allow of its being raised and lowered as required. F is the horse wheel
on the outside whereof are bolted or otherwise fastened two bars G. The inner
ends of these bars are connected together and are fastened to a block which block
carries a pin H. A. whipple h is secured to such pin and to this whipple the
traces of the horse are fastened. The wheel F is kept in a horizontal position
by the spindle f. This spindle also serves to form the axis upon which the
carriage turns. The horse in travelling round the back of the machine and under
the grasshopper limb rotates the wheel F thus imparting motion to a small cog
wheel I mounted on the inside of the frame. This cog wheel in turn imparts
motion to two bevil wheels J J¹ the wheel J being mounted on one end of the
spindle that carries the cog wheel I while the wheel J' is mounted on an inter-
mediate spindle. The spindle of the wheel J' carries a pulley K over which a belt
or chain runs to the pulley L at the back of the machine by which motion is
imparted to the spindle M. This spindle carries a pair of pullies (not shewn in the
drawing) that are fitted inside the trough and over which an endless chain
furnished with tines works so as to raise the feed when fed into the trough. N are
struts which together with the bars G form part of the carriage on which the
machine is locked round when it is desired to move it from place to place. To
effect this the struts are raised and fastened to the bars G by pins or bolts p as
shewn in Fig. 2. These pins or bolts also secure the ends of the shafts P to the
bars G by the cross bar Z and such shafts are further strengthened by being
threaded on to the pin H at the underside. These shafts serve to draw and lock
round the machine as required. R are the travelling wheels of the machine.
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
1. In a stacking machine or elevator two auxiliary or grasshopper limbs placed
one on each side of the frame thereof and otherwise constructed and arranged all
substantially as hereinbefore set forth.
2. In a stacking machine or elevator the combination of the spindle or shaft
carrying the horse wheel with struts N and bars G so as to form an axis whereon
the front wheels of the machine lock round and as a bearing to assist in carrying
the weight of the trough all substantially as set forth.
