Improvements in Apparatus for Raising and Stacking Hay, Straw,
and other Substances.
I, HENRY REEVES, of The Butts, Bratton, Westbury, in the County of Wilts,
Agricultural Engineer, do hereby declare the nature of this invention to be as
follows:-
The elevating troughs are made of steel angles and channels braced with
steel bars and covered with galvanized corrugated sheet iron.
The sides of these troughs are made the full depth required without the aid of
movable side boards.
The two elevating troughs are jointed together in the usual way, the hinges
being placed on the top edge of the troughs, and to avoid the undue strain or
tightening of the elevating chain when the troughs are being turned over, I make
the bearings or blocks which carry the top elevating chain pullies, to slide on the
framing of the top trough. These blocks are held in place by two or more rods
passing through the blocks, and having screw threads on them for the purpose of
adjusting the top pullies when it is requisite to tighten or slacken the elevating
chains to enable them to work properly. These adjusting rods are carried the
whole length of the top trough and the ends come against the bottom trough.
When the top and bottom troughs are opened out to their full length for work
these rods are used for adjusting the top elevating chain pullies, but when the
troughs are being turned over or folded up, they slide on the frame to release the
top chain pullies and thus prevent the undue strain or breaking of the elevating
chains.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of an apparatus constructed according to this invention
.opened out ready for use.
Figures 2 and 3 are transverse sections on the lines 2-2 and 3-3 Figure 1.
Figures 4 and 5 are local longitudinal and transverse sections showing the sliding
bearings g and rods h to a larger scale and
Figure 6 is a detached view of one of the rods h.
a is the upper trough and 6 the lower trough which are made as shown of steel
angles c and channels braced with steel bars and covered with corrugated sheet
iron. These troughs are hinged together at c. d d are the top elevating chain
pulleys which work on the axle c carried by brackets carried by blocks g which
are grooved to receive the lower webs of the angles c upon which they slide.
hh are rods working in guiding eyes j (Figure 3) fixed to the angles c. The lower
ends of the rods h abut against the top of the trough 6 whilst their upper ends are
adjustably fixed by means of screw threads (see Figure 4) to the blocks g.
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. Carrying the top elevating pulleys on slides free to move downwards when
the elevator is being folded but prevented from so doing when it is extended.
2. The rods h adjustably fixed to the sliding bearings of the top elevating
pulleys and abutting against the lower trough.
3. Apparatus substantially as described and shown in the drawings.
