COMPLETE SPECIFICATION.
Improvements in and relating to Appliances for Lifting or
Elevating Out Crops, Fibrous and Granular Material, and
the like.
I, HENRY BOAK FLEMING, of Haugh, Kirkliston, Linlithgowshire, Farmer,
do hereby declare the nature of my invention, and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement in writing, that is to say :-
This invention has reference to and comprises new or improved portable
appliances for lifting or elevating cut crops such as hay or straw, wool or other
fibrous material, coal dross, clay, sand or dung and the like, and specially
applicable for forming the temporary ricks of cut crops on the field in which
the crop 18 cut; but also suitable for forming the permanent stacks, or for
elevating the crop or other material into storage buildings, or for shipment and
like pui poses.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings in which
Figure 1 represents an elevation in perspective of one arrangement of my
improved appliances as suitable for catching and elevating cut crops, and showing
said appliance in the holding position.
Figure 2 is a view corresponding to Figure 1, showing the appliance in the
liberated position for delivoring the cut crops.
Figure 3 is a perspective view showing the appliance in the position shown in
Figure 2 as depositing the cut crops on to a rick or stack which is being
formed.
Figme 4 is a view corresponding to Figure 1 showing the appliance as slightly
modified to suit for digging into and elevating sand, dung, or like material.
Figues 5 and 6 are an elevation and plan view respectively to an enlarged
scale and broken away, showing the engaging and releasing gear of tho aforesaid
appliances; and Figures 7 and 8 are detached elevatious, at right angles to each
other, of a slightly modified arrangement of same,
Figures 9 and 10 are elevations with one of the side plates removed, showing
the appliances as modified to suit for digging into and elevating a load of cut crops
and the like, and
Figures 11 and 12 are side and end elevations corresponding to Figures 9 and 10.
Referring to these drawings.-As applied to the forming of the temporary
field ricks, as shown in Figure 3, a vertical mast or derrick pole a 18 erected on
a two wheeled cart or it may be a four wheeled lorry, wagon, or vehicle
suitable for moving about to any desired part of the field This derrick pole a
would preferably be formed of tubular steel or metal and pass through a socket
eye a¹ on a bracket at the back end of vehicle b, and may have its lower end
made telescopic to slide over or past the upper part and penetrate the ground
at and may be anchored by prongs or other gripping devices and may be locked
to the upper part at a³. A series of stay tubes rods, or wire ropes would be
fitted between the upper end of derrick pole a and the vehicle b, while guide
pulleys a would be fitted on a tubular or other framing a projecting out from
the upper part of the pole a like the jib of a crane, and a hauling rope b³ would

page_text: be passed round these pulleys a' and have its one end attached by a shackle link
or hook at to the hay lifting appliances hereinafter described, while its other
end would pass round a pulley as or pulleys at the lower part of pole a and a
hose be attached by traces to it; o instead of a horse a hand winch or small
engine may be used for winding the rope and elevating the hay; or blocks and
tackle may be used.
The appliances for gripping and lifting the hay or cut crop would under one
arrangement, as shown in Figures 1 to 3 consist of a metal frame A to which
fitted a series of hook shaped or curved bars A' passing through slots in a
transverse plate A³ and secured at their upper ends in a similar plate A'. Another
frame B, which I term an engaging and disengaging lever frame, 18 fulcrumed or
mounted on the frame A by a transverse spindle B' passing through eye bearings
at B, and the upper end of this frame B is portably connected to the frame A
by an engaging device when a load is to be elevated, and said device is disengaged
when the load is to be libeinted and lowered. This device, as shown to an
enlarged scale in Figures 5 and 6, would consist of a U shaped link C fulcrumed
at C on the frame B, and engaging with the hooked arm A" of the frame A.
The book C is held in spring tension by an india rubber o elastic spring c
passing round catch hook c on it and on the frame B, while a double cheeked
lever D fulcrummed at D' is also held in spring tension by an india rubber spring
passing round hook pins d' on the lever D and a link D³ secured on the frame A.
The shackle end of the rope 6 is attached to the eye D³ of the lever D and
passes through a guide cye D in the link D as shown in Figure 1. In elevating
a load of crop the appliance is in the position shown in Figures 1 and 5, but when
in suitable position for depositing the load the cord & is pulled, and the lever D
lifts the link C and so disengages the frames A and B which assume, the position
shown in Figures 2 and 3. In the arrangement shown in Figures 7 and 8, the
upper part of the frame A passes through the open frame B, and is held in
position by the lever D fulciumed at D and kept tension by the rubber
spring d. This lever D bears against the projecting head A" of the fiame A,
and when the cord is pulled the lever D is tilted and so liberates the frame A
to swivel to the depositing position.
The arrangement of appliance, shown in Figure 4 is suitable for digging into
and elevating sand, clay, and the like, and it is formed with solid metal at the
sides A and transversely between these, either separate from the prongs A' or to
cover these, and have pronged ends A' at the front to dig into the fnaterial to be
elevated, while a bridge piece A would be formed at the back for pressing by
hand the appliance into the material. In working stiff clay and the like, chams or
ropes A may be attached to hooks A' to pull the appliance by a winch or other
device into the material to fill the elevator, while a steam craue may be used for
lifting the load.
By an alternative arrangement, as shown in Figures 9 to 12 the gripping
prongs A' would be spread out in grabbing the hay and be oscillated inwards when
liberating and depositing the load This would be effected by constructing the
appliance in the form of a two checked open frame E stayed together by internal
transverse pins on rivets E' and having a solid sharp pointed end E' at the lower
part for being projected into the compressed hay, and an eye head E3 at the upper
end of frame for attaching the elevating rope or tackle to.
A vertical moving
rod or har e would be mounted between the checks E of this frame to reciprocate
or slide up and down and have strengthening bs e" formed on its sides. The
upper end of this vertical rode would be jointed at e' to the lower end of a cuived
linke and the upper end of this link e would be connected at e³ to the one end of
an operating lever et fulerumed on a transverse pin es between the checks E of
frame. The lower end of the sliding rod e would be formed with lugs ex e*,
preferably two, projecting from opposite sides and a gripping prong A¹ would
be loosely jointed at its one end preferably by a pin A* to each of these projecting
Jugs e. The prongs A' would be set to diagonally cross each other and

page_text: preferably be of a curved nearly straight shape with pointed free ends to grip
the hay.
In using the appliance the free end of the upper operating lever e¹ would be
depressed or drawn downwards by the cord b and this would raise the connecting
link e and vertical sliding rod e, and the diagonal crossing prongs A' at lower end
of rod would be made to slide upwards and inwards within the cheeked frame by
projecting studs E on inner surface of checks E bearing against them and making
them oscillate on their pin joints A* to swivel within the frame E. The appliance
would then be projected by hand or otherwise so that its pointed end may enter
with some force into the hay or straw and the free end of operating lever e would
be raised to depress the vertical rod e and make the prongs A' to swivel outwards
past the projecting lugs e* until they assumed a position nearly at right angles to
the frame, as shown in Figure 9 so as to properly grab and hold the hay. When
the load bas been olevated to its proper depositing position, the free end of lever et
would be drawn downwards by the ropo or chain 6 attached to it and passed
through a guiding eye and pulley on a projecting bracket D' on fraine E to a
position couvenient for the attendant to operate same, and so raise the sliding rod e
and swivel the prongs A' within the frame E, to the position shown in Figure 10,
to liberate and deposit the elevated load.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same 18 to be performed, I declare that what I
claim 18:-
First. The appliances for holding and elevating material constructed and
operated, substantially as and for the purposes herein described in reference to
and shown in Figures 1 and 2 and 4 to 8 of the accompanying drawings.
Second. In appliances such as shown in Figures 1 to 8, the arrangement and use
of engaging and disengaging frames constructed, substantially as herein described
in reference to and shown in the accompanying drawings.
Third. The appliance constructed and operated substantially as and for the
purposes herein described in reference to and shown in Figures 9 to 12 of the
accompanying drawings.
