SACK TACKLE APPLICABLE FOR GENERAL RAISING & LOWERING PURPOSES
Year: 1884

page_text: I JAMES WILLIAM PORRITT at the Office for Patents 323 High Holborn in the
County of Middlesex, Farmer, do hereby declare the nature of the said invention for
SACK TACKLE APPLICABLE FOR GENERAL RAISING & LOWERING PURPOSES to be
as follows:-
The object of this apparatus is to facilitate the employinent of horse or similar
power for hoisting or lowering by means of a line passing round suitablo pulleys.
The apparatus consists of a top pulley or sheave carried in any convenient form
of swivelling block or frame work and also in most cases free to travel along
suitable rods or guides or it may have a hook so that it can be suspended wherever
it may be wanted.
Below there is another pulley situate in a movable head which permits of.its
being turned to the proper line with the top pulley. This head is preferably
provided with a fan-like tail piece having holes or equivalent through which a pin
may be passed so as to fix it at the proper angle.
This moveable head may be permanently jointed to the building where there is
regular use for it in one particular place, but for use for hoisting grain & on a
farm or similar purposes where it is frequently necessary to change the position
I prefer to sink a trunk or socket in the ground into which a holder which carrios
the movable head can be placed when required-If this be square in cross-section
the pulley can be turned in four directions and this is usually enough for ordinary
requirements; however I do not restrict myself to that form and may make the
hole round or other shape if preferred and fasten the head with a set screw or
equivalent device.
.
In addition to the trucks sunk in the most important places I may have
portable ones which can be sunk wherever needed-as in the middle of a field-at
a moment's notice. In such cases I usually provide a tripod or shear legs to carry
the top pulley.
•
The action is as follows.
One end of the line is attached to the Sack or whatever has to be lifted, and the
other is passed round the pulleys and secured to the horse or other source of
power. The horse runs off with the line and lifts the sack &° which when it
reaches its destination is unshipped and the line returned for a fresh load.
By this apparatus I can allow the horse to travel in any required direction and
wherever there may be room, the pulleys adjusting themselves to the requirements.

page_text: I, JAMES WILLIAM PORRITT at the Office for Patents 323 High Holborn in the
county of Middlesex, Farmer, do hereby declare the nature of invention for "SACK
TACKLE APPLICABLE FOR GENERAL RAISING AND LOWERING PURPOSES" 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 to a handy apparatus for use on farms and in many other
places where a load may be raised by animal or other power applied at one end of
a rope or equivalent, the load-being at the other end.
In the accompanying Drawings Figure 1 is a front view of the chief portion of
the apparatus and Figure 2 a side view of the same. Figure 3 shows how it may
be utilized in an open space, as a field, by the use of shear legs. A is a trunk or
socket which may be sunk in the ground either as a permanency, a trunk being
placed in each of the positions most frequently required, or the trunk can be
carried about with the rest of the apparatus and sunk in the ground when and
where required for use.
Where the surroundings are suitable the trunk may be fastened in any suitable
manner without sinking it in the ground.
B is a jaw carrying the movable head C pivotted at C¹ which has the fan tail D
perforated with holes E through which and the jaw passes the pin F which thus
secures the head C in the position required. Or the pin and holes may be
dispensed with and a set screw or equivalent substituted.
The jaw B fits into the trunk A as shewn and may be fixed by a pin H or
equivalent device such as the lid P booked at P¹ and entering the jaw B as
shewn the tail of the jaw and the hollow of the trunk are shewn square in the
drawing, but any other suitable form of cross section may be adopted; the square
being convenient and in practice found to auswer well.
The head C can thus be turned to face in any required direction in the trunk to
suit the line which must be taken by the horse or other animal in pulling the rope,
while it can also be canted over to suit the position of the top pulley 1 Figures 2
and 3 so that a fair pull may be obtained. The head C carries at its upper end
the pulley K round which the rope L is passed, and in any suitable position above
the load is the pulley I by preference hung so as to be free to turn in any direction
as shewn in Figure 2.
The apparatus is used as follows:—
The load M Figure 3 is attached to the rope L which passes round the top
pulley 1 and down to the second pulley K round which it passes and its other end
is fastened to the horse or other source of power. As the rope is pulled the load is
run up and may then be deposited where required.
It will be seen that this apparatus can be arranged so that the horse can travel
in whatever direction may be most convenient, so that if one direction will not
suit it can be turned to another which does.

page_text: The application shewn in Figure 3 is adapted for open fields or similar places
where there is no building to carry the pulley I and the shear legs are therefore
substituted. This arrangement is useful for loading sacks of grain which have
been threshed in the open field into carts and for similar purposes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In an apparatus such as described the jaw B carrying the movable head C in
combination with the trunk A substantially as and for the purpose specified.
2. The combination with the jaw B of the movable head C pivotted at C' and
having the fantail D whereby it may be secured in the required position by the
pin F or equivalent device substantially as specified.
3. The movable head C carrying the pulley K at its upper end and pivotted
at C¹ so that it may be set to the required angle and retained in that position by
the fantail D substantially as specified.
4. The combination with the movable head C of tho jaw B arranged to fit in the
trunk A or be turned therein so as to present the pulley K in the direction
required substantially as specified.
5. The combination with the jaw B and movable head C of an adjustable
pulley I for the purpose specified.
