Improvements in Presses suitable for Bundling Hay and Clover..
I, WILLIAM JANSON PERKINS, of North Duffield, near Selby, in the County
of York, Blacksmith, do hereby declare the nature of this invention and in what
mauner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
This invention consists in improvements in the construction of presses suitable
for bundling hay and clover and has for object inter alia, to furnish means for
enabling the position of the fulcrum of the beam to be very easily and quickly
changed and for suspending the beam whilst the position of its fulcrum is being so
changed.
In order that my invention may be fully understood I will proceed to describe
with the aid of the accompanying drawings apparatus constructed in accordance
therewith.
Figs. 1 and 2 are respectively a side elevation and an end elevation of a bundling-
press according to my invention;
Figs. 3 and 4 are respectively a cross section and a partial side elevation, drawn
to a larger scale, and showing the fulcrum-pin device used in the apparatus; and
Figs. 5 and 6 are respectively a plan and a partial side elevation of one of the
supports for the beam, showing my improved bearings for the fulcrum-pins.
On the foundation-board 1 is secured by means of bolts 2, a bracket 3 to which
are bolted the uprights 4 and 5 which may be of channel-iron, as preferred and
shown, or of metal of any other suitable cross section. The uprights are provided
in their inner sides-when of chanuel-iron, in their inside flanges as shown, with
slots 6 which have round ends and each of which has one of its side walls cut away
sufficiently (see Fig. 6) to allow the corresponding fulcrum-pins 7 to pass there-
through. The upper round end wall of each of these slots is adapted to act as
a bearing for the corresponding fulcrum pin when the beam is being pulled down
to compress the material that is being bundled and the lower round end wall of
each slot is adapted to support the corresponding fulcrum pin when the suspending
chain 8 is being connected or disconnected from the fulcrum pins.
The fulcrum-pins 7 which are usually formed in one piece as shown, are secured
by casting or otherwise in a saddle-piece 9 which is clamped to the beam 10 by
a strap-bolt 11 furnished with screw-threaded ends 12 and 13 and nuts 14 and 15.
At the middle of the saddle-piece 9 there is provided a hook 16 (or an eye), which
is connected by the suspending chain 8 to one end of a double armed lever 17
adapted to oscillate on a stud 18 carried by bearings 19 on the end of a rod or
support 20, which is secured to one (viz. 5) of the uprights, the other arm of the
lever 17 being connected by a coiled spring 21 with a bracket 22 which may be
formed on the lower end of the rod or support 20, as shown, or be secured to the
upright 5 separately therefrom. This spring, lever, and suspending chain
arrangement normally keeps the fulcrum-pins 7 in contact with the upper end
walls of the corresponding slots 6 in the uprights 4 and 5 and also supports the
beam whilst its fulcrum pins are being removed from one slot to another."
Ou the short end of the beam 10 there is hung a weight 23 which is sufficiently
heavy to keep tight the beam operating rope or chain 24. This rope is secured by
a hook 25 to an eye bolt 26 fixed to the long end of the beam 10 and passes round
a guide pulley 27, which is arranged to revolve on a shaft 28 carried by
bearings 29 on the frames 30 & 31 of the winch and is free to move sideways on.

page_text: the shaft 28 to suit the various positions assumed by the rope 25 when being
wound on the winch barrel. The frames 30 & 31 are kept the required distance
apart by stretcher bolts 32. In bearings 33 & 34 at the top of the frames 30
and 31 there is mounted a shaft 35 carrying the winch-barrel 36, which is arranged
to be rotated by a toothed wheel 37 fixed on the shaft. 35, and gearing into
a pinion 38 fixed on a shaft 39 mounted in bearings 40 & 41 and provided with
a crank handle 42.
On the foundation-board 1 near the uprights 4 and 5 is placed a grid-like
table 43 on which the material a toibe.compressed.is placed. Between the bars 44
forming the grid are placed. hoops used in binding up the pressed material. On
the top of the material a is placed a movable grid constructed of a number of
bars 45 secured, at convenient distances apart to a round backed cross-piece 46
which is intended to receive the pressure from the beam 10 through a cup or
hollow cross-piece 47 secured thereto, the hollow-cross-piece 47 forming with the
round backed piece 46 a knuckle-joint and keeping, the two in contact whilst the
pressure is applied.
Having now. particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. A bundling-press of the kind referred to, having bearings for the fulcrum-
pins of the beam formed by slots each of which has an opening through, one of its
side walls adapted to enable the position of the fulcrum of the beam to be readily
changed, substantially as herein before described.
2. In a bundling-press of the kind referred to, the saddle-piece provided with
fulcrum-pins. and secured to the beam substantially.as hereinbefore described and
shown.
3. In a bundling-press of the kind referred..to, .the means substantially as
herein before described for suspending the beam during the operation of changing
the position of its fulcrum.
4. My improved bundling-press constructed, arranged. and operating as herein-
.before described with reference to and shown in-the accompanying drawings.
