I HENRY YORATH of 22 Charles Street Cardiff in the County of Glamorgan
Implement and Manure Agent do hereby declare the nature of my Invention
for "IMPROVEMENTS IN APPARATUS FOR ELEVATING AND MORE PARTICULARLY
DISCHARGING HAY CORN AND OTHER CROPS ON TO STACKS" to be as follows:-
For the purpose of explaining with clearness the working of my invention
I mention and make use of certain arrangements previously patented but upon
which the patent has expired.
I erect a pole about 36 feet in length placed in the ground to the depth of 12 in
to 18 inches by the side of the stack secured at the top by four stay ropes, and at
the bottom by stay bars driven into the ground. Upon the top of the pole are
three iron cups placed one on top of the other and with a flange to each. Upon the
lower cup is an iron ring with two links placed loosely so as to turn easily on the
cup, upon the middle cup is an iron ring with six links placed similarly, and upon"
the upper cup is an iron ring with four loops for fastening the four stay ropes.-
Within two feet from the bottom of the pole is a pulley wheel placed in the
centre, on each side of which is an iron bracket with a small roller at each end.
About two feet above those brackets and on the other quarter of the pole are
two other iron brackets for fastening the ends of pulley block ropes. Placed
loosely above the iron brackets is a tension ring and resisting chain and pulley
block and roller-Placed against the pole is a gaff with two pulley wheels one at
each end,and with two wheel guides fixed to the gaff. There are a pair of single
and double pulley blocks prepared with rope, the double pulley block being
attached and suspended from the chain of the lower cup, and the single pulley
block to the ring of the tension chain and the hook of the tension chain to the near
wheel guide of the gaff, the end of the rope being fastened to the rope-bracket
Another pair of double pulley blocks prepared with rope, one of which is attached
to and suspended from the chain of the middle cup, and the other to the outer
wheel guide of the gaff, the one end of the rope running over the tension chain
pulley wheel and secured to the long link at the fore-end of the gaff, and the other
end fastened to the lower rope bracket-A rope is passed over the pulley-wheels of
the gaff, one end of which descends and passes under the pulley at the bottom of
the pole and then attached to a harnessed horse (which I shall call hereafter the

page_text: horse rope) and to the other end of which is suspended a claw shaped fork-By
twisting the ropes around the rope-bracket the gaff will be raised to the height
required keeping it at the same time as near as possible to an angle of 45°.
I have now come to the part upon which I claim my chief improvement`and
which consists of a peculiar new pulley bracket and pulley block called for the
purpose of identification in the drawings sent herewith say A and B.
A is a bracket having a circular hole in the middle about 3 in: in diameter at the
bottom and 2 in. at the top with a depth of about 2 in: It consists of two
mortice arms extending in opposite directions containing a pulley wheel within
each mortice, and two small slotted arms situated on each side of the circular hole
extending at right angles to the two mortice arms.
B, is a single pulley block at the lower end of which is a square hole running
parallel with the pulley wheel with an axle fixed in the mortice having a round
projection at each side about one in. long with a 1, in split key hole attached to
the B pulley block are two claw shaped forks (upon which forks I claim no novelty
as regards shape), placed one each side on the circular projection of the axle of this
arms of
pulley block, the upper end of each fork is connected with the slotted
pulley bracket A by a bracket-Four inches from the connecting part of the claw
shaped fork are two chains one on each side joined together at the top to the ring
connected with the horse rope so that when the horse is driven on the angular
shape of the chain cause the forks to close and retain their load.
ni
To unload a wagon by this method the two forks are drawn apart as wide as
they permit and then pushed into the hay or other crop required to be unloaded,
the horse is driven on consequently causing the forks to close and ascend and when
required to be discharged the man on the load pulls down the rope which is
fastened to. B pulley block and which runs over both pullies in bracket A
producing therefore a double leverage and causing the forks to open and discharge
their contents.

page_text: I HENRY YORATH of Number 22 Charles Street in the town of Cardiff in the
County of Glamorgan Implement and Manure Agent do hereby declare the nature
of my invention for IMPROVEMENTS IN APPARATUS, FOR ELEVATING AND MORE
PARTICULARLY DISCHARGING HAY CORN AND OTHER CROPS ON TO STACKS and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
For the purpose of explaining with clearness the nature and working of my
invention, I mention and make use of certain arrangements previously Patented
Patent 3951 now expired, thus
I erect a pole about 36 feet long placed in the ground from 12 to 18 inches,
about 6 inches in diameter at the butt, and tapering to 3/2 inches at the top,
secured at the top by four guy ropes and at the bottom by four stay bars at a
convenient distance from the butt of the pole, the said ropes holding up the pole in
the position required, and the pole should lean towards the stack to the extent of
about 18 inches or as much as to cause the gaff or extended arm to turn round
easily to the centre of the stack. Within 2 feet of the ground a mortice is made
in the centre of the pole and a grooved pulley wheel placed therein. Against the
pole is placed a gaff or extended arm, with a grooved pulley wheel fitted at each
end, and with pulley wheel guides with eye to each. From a ring and links at
the top of the pole there are suspended two pair of pulley blocks prepared with
rope, one pair being fastened to the eye of the wheel guide at the fore-end of the
gaff or extended arm, and the other to the eye of the wheel-guide at the bind end
of the gaff, by which the gaff can be raised to the height required in working and
the ropes are fastened to rope brackets at the butt of the pole. Before raising tho
gaff however higher than you can reach a strong rope is placed over the two pulley
wheels of the gaff and under the grooved pulley wheel placed in the butt of the
pole, to this end a horse is attached, and to the other end (that is placed over the
two grooved pulley wheels at each end of the gaff) a large fork is suspended, so
that when the gaff has been raised sufficiently high, the fork is ready to receive its
load; so much appertains to the expired Patent-There are three Improvements
added to the old Patent, which will be used in the working of the new clip fork,
and are explained here for the sake of a clear understanding how they occur on the
drawings submitted with the Provisional Specification but which do not form a
part of my claim (1st). I place on the top of the pole, three flange cups; on the
first I place a ring with two links, and on the second a similar ring with six links,
and on the third a ring with four eyes to those eyes are tied the four guy ropes, a
washer is placed on the last cup and a half-inch bolt through the pole to keep the
cups together, enabling by this arrangement the gaff to be turned to either side of
the pole and proving very advantageous when a large stack is being made.
Attached to the above rings are two pairs of pulley blocks referred to before, one
pair consists of a single and double pulley, and the hook of this double pulley is
attached to the lower of the two links on the first cup, and the book of the single
pulley to the ring of the resisting chain (hereafter explained); the other pair mo
two double blocks, one being hooked to the last link of the ring with six links on
'

page_text: the second cup and the other to the eye of the wheel guide at the fore end of the
gaff. (2) The resisting chain and ring is a double angle chain with ring pulley
block and roller attached the ring is placed about the pole and the angle chain
keeps the ring suspended at right angles to the pole. There is a roller at the back
for the purpose of enabling the ring and chain to slide easily over the pole when
the gaff is being raised. Attached to the ring opposite this roller is a single pulley
block which receives the end of the rope from the double pulley block at the outer
end of the gaff causing consequently a counteracting force on the back of the pole
to meet the pressure produced upon the front when the gaff is at work (3) a pair
of cast iron brackets with a mortice to each and a small roller inserted at each end
The brackets are placed each side of the grooved pulley at the bottom of the pole;
the horse-rope is passed between the upper roller and pole and under the grooved
pulley to the lower roller on the other side, keeping the horse-rope in its place and
so preserving it from undue wearing and friction.
I have now come to what I claim as my new Invention which consists of a
double crab or claw fork fitted with two peculiar pulley brackets marked for
identification on the Drawings furnished with the Provisional specification A
and B; A is a pulley bracket with a centre hole from 2 to 4 inches in diameter
at the bottom. and from 2 to 3 inches at the top and with a depth of 2 to 3 inches
(this variation in measurements is to meet the size of the claw fork required)
through this hole the horse-rope is drawn This pulley wheel bracket has two
morticed arms extending in opposite directions, with a 3 inch pulley wheel in each,
and at each side is a small slotted arm (marked on the Drawings C) which receives
the lever arm and is bolted to it. This lever arm at the other end has a slotted
head to receive the end of the claw fork, and similarly with the other side, to form
an angle.
In
B is a pulley block and bracket having a 3/4 of an inch hole either round or
square beneath the pulley wheel and running parallel with the pulley wheel
this hole is inserted a short axle 3/4 of an inch in diameter having a turned pro-
jection of 3 of an inch at each side with a nut and split key. Upon these
projected parts are placed the arms of the claw fork and secured by the nut and
split key, and then the ends of the claw fork are bolted one to each of the slotted
head of the lever arms of pulley bracket A. About 6 inches from the centre of the
above axle is half an inch hole in each of the arms of the claw fork, and attached
to each of these holes is a shackle forming part of a small chain about 18 inches
long containing two links in the centre. The horse-rope is fastened to one of those
links, so that when the horse is attached to the other end of the rope and driven
on so the chain forms an angle between the two arms and draws them together. and
consequently the two claws are also drawn together in like manner gripping and
retaining the material until in a position to be discharged and this is done simply
by previously fastening to the eye at the top of pulley bracket B a rope about ten
or twelve yards long then running it over the inner side of the pulley wheel in one
of the projected arms of pulley bracket A and down and under the pulley wheel in
pulley block B back over the inner side of the pulley wheel in the other projected
arm of pulley bracket A and finally down to the man on the load who by
drawing this rope produces a double leverage inasmuch as the two pulley brackets
are drawn together and at the same time the claws of the fork open and discharge
their contents on to the stack. This rope serves the purpose also of drawing or
rather guiding the claw fork to its proper place to be refilled which is done in
a very easy manner, the man having only to draw one side apart as far as it will
admit and push it in the stuff or material and do the same with the other side
when it is again ready to be drawn up and discharged.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I déclare that what
I claim is
1. The construction, application and action of the claw fork and pulley wheel
brackets marked A and B, the advantage and utility of which consists in the

page_text: perfect and easy way its contents can be discharged at any height and at any time,
by having the rope placed in such a position that it cannot get entangled and by.
having the whole under the absolute control of the man on the load whose work
however may by this arrangement be as easily and as effectively performed by a
boy of 15 years of age and thus shewing that an arduous and important work can
be despatched with ease I do not claim the other arrangements hereinbefore
described.
