JOHN STURDY HALL and CHARLES EDWARD VINCENT HALL, Engineers, of the
Midland Iron-works, Nowark-on-Trent, in the County of Nottinghamshire, do
hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements in the construction of self-load-
ing and self-unloading barrels, packages, or goods that can roll or slide.
We adopt a swinging cage, or swinging cages, attached to two chuins working
over sprocket wheels, fixed at the top of the building or above the highest floor
on to which it is desired to raise the goods; in connection with a moveable T-
iron floor worked by levers.
The above mentioned swinging cage or cages are arranged so that the goods
are lifted up on one side, passing over the top and descends on the other side of
the centre of the sprocket wheel, and delivers it on the required floor.
Supposing we have to raise some barrels holding 54 or 36 gallons a lever is
dropped into its proper position, so that the T-iron forks lie horizontally and
level with the floor line; upon these forks the barrels are rolled, finding their
own position on the forks, which latter are bent to receive them.
The swing cage, or cages, attached to the two chains, coming up takes the barrel,
or barrels, off the forks carrying them round the top and over the shaft, by means
of the sprocket wheel, through which they swing by their own weight.
The descending chain and cage deposits the barrel on to two forks, moved into
position by another lever, from whence the barrel rolls upon the floor clear away
from the hoist.
When it is required to raise smaller barrels, from 18 down to 6 gallons capacity,
another lever is moved, bringing into action a pair of forks placed closer together
to take the smaller barrels.
The ascending cage takes the barrel off and carries it and deposits it on to
another pair of forks.
Should it be required to place any barrel upon any floor, all the forks are
removed out of the way into a vertical position, except the forks on the floor on
to which the barrels are to be delivered, placed horizontally.
If the attendant should by forgetfulness, or accidentally forget to remove the
forks, when required, no harm or damage can be done by the barrel, as it will lift
the floors upwards, as it ascends and go round the sprocket wheel until taken off
by the attendant lowering the forks on any floor, as desired.
Datod this 13th day of November 1899.

JOHN STURDY HALL and CHARLES EDWARD VINCENT HALL, of Newark-on-
Trent, in the County of Nottinghamshire, Engineers, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement :-
This invention has for its object improvements in the construction of self-
loading and solf-unloading barrels, packages, or any other class of goods that cau
roll or slide, such as brewers casks, barrels, drums, rollers, and the like, also
trolleys, trucks, packages, carriages and the like, and any other class or classes
of goods, which will either slide or roll.
This object is attained by the adoption of swinging cago or cages, attached to
two chains working over sprocket wheels, fixed at the top of the building or above
the highest Hour on to which it is desired to raise the goods; in connection with
a moveable T-iron floor worked by levers.
In order that this invention may be clearly understood we append herewith two
sheets of drawings:
Figure 1 is a front elevation;
Figure 2 is a side elevation.
Figure 3 an enlarged plan.
The loading of barrels is accomplished by rolling them on to the T-iron aṛms A,
from the cellar or floor on which they are stored. These arms are secured upon
a shaft, B, which carries brackets holding T-irons, shaped to receive the barrels,
holding them in position until the two ascending chains, C and C, between which
are secured swinging or skeleton cages, D, takes the barrel off, automatically,
the barrels rolled thereon, carrying them over the top shaft and through the
sprocket wheels, E and E, to descend and be delivered upon any floor desired by
the attendant placing the taking-off arms F and F, in position to receive the
barrels, which roll themselves off upon the desired floor.
The swing cage, D, is made in a zig-zag form, as shown in Figure 3, so as to
clear on its upward movement the loading arms, A and C, and on the downward
movement the unloading arms, and F. The cage consists of two outer bars, H
and H. which are secured by pivots to the chains, C and C. J, J, J, and J are
bent bars, as shown at 1) Figure 2, the two inner bars being bent to a larger
radius to suite the curvature of the barrels. All these bars may be made in one
piece or they may be welded or rivetted together, in any way found most suitable
and convenient.
Should it be required to place any barrel upon any floor, all the forks or arms
are moved out of the way into a vertical position by the levers, except the arms
on the floor to which the barrels are to be delivered, these arms being placed
horizontally.
If it should happen that by any neglect the attendant leaves any of the arms A
and G, other than those which should be used at the time, in position, no damage
can be done, because the ascending barrel and cage will lift the arms, A and G,
out of the way automatically, and passing through them, delivering the barrels
upon the desired floor on descending, or go continuously round until taken off
by the arms, and F, being dropped into position.
If it is desired to raise 6, 9 and 12 gallon barrels the arms G G are dropped
down horizontally and the barrels rolled on from floor opposite the end of The
arms.
The action of the hoist is as follows: --Supposing that the barrels are in the
collar and it is required to raise them to the top floor, and the barrels are of a

page_text: large diameter, say 54, 36 and 18 gallons capacity, place all the arms A, on the
bottom floor, into a horizontal position and all the other arms A, and all the
arms in a vertical position on the ascending side of the hoist. If the barrels
are small, such as 12, 9 and 6 gallons capacity, the arms G on the bottom floor
must also be dropped down by the lever into a horizontal position. On the
opposite or descending side place the top unloading arms, F and F, in a horizontal
position and all the other armis, F, vertical. Now it is evident if we place a
barrel on the arms A on the bottom floor that when the swinging zig-zag cage
comes down on one side and rising on the other it will pass through the arms A,
when large barrels are raised, and arms A and G when small barrels are raised,
and carry with it the barrel placed on them. The cage with the barrel will continue
its upward movement, pass through the sprocket wheels, E and E, at the top and
commence descending on the other side, but the cage will pass through between
the armis, F and F', leaving the barrel on the arms, however, as the arms, and F,
are placed at an incline the barrel will roll off then on its own accord. From
this description it will be seen that the attendent has no need of going near the
hoist when it is working.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
First In coutinuous automatically delivering hoists with skeleton cages
constructed as illustrated, in such a manner that they will pass between the
receiving and delivering arms, substantially as herein before described.
Second-The arrangement of arms for receiving the barrels or other goods
of large dimensions, substantially as hereinbefore described.
Third: The arrangement of arms, for receiving small barrels or other goods
placed opposite to and between the arms for receiving the large barrels or other
goods, substantially as herein before described.
Fourth-The arrangement of receiving arms so that they can be lifted out of
the way by an ascending barrel or other goods, in case the attendant should leave
the wrong arms in position during working, substantially as herein before
described.
Fifth Automatically delivering hoists, so arranged that the barrels or other
goods are raised on one side of the sprocket wheels and delivered on the other
side of the sprocket wheels.
Sixth Swinging skeleton cages made in a zig-zag shape, so that they can
pass between the T-iron armis, when they pass up and down, substantially as
hereinbefore described.
