PROVISIONAL SPECIFICATION.
Improvements in Cask Elevators.
FREDERIC GEORGE RILEY of 256, South Lambeth Road in the County of
Surrey Engineer do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in raising casks.
I employ an ordinary hoist provided with a cage and counterbalance and I
operate same by means of two belts travelling in reverse directions ou fast and
loose pullies on a shaft provided with a worm, the latter engaging with a worm
wheel keyed on the main shaft carrying either a rope or chain wheel to raise and
lower the cage. The bottom of this cage has pivotted to it a cradle to carry the
cask or casks and is shaped so that they are always central when placed on same.
This cradle is hinged at one side out of the centre and below this I provide a shaft
carrying cranks to raise and lower one side of the cradle, this shaft is prolonged
beyond the cage on one side and has a lever secured on the prolonged side which
engages with a stop secured to the main frame forming the guides for the cage in
such a manner that when the cage has arrived at any desired point, this lever is
depressed and the cradle is tilted causing the cask to be thrown out. I provide an
endless chain passing over a loose pulley secured near the ground and carried
through the cage and the other end over a chain wheel fixed on a shaft in suitable
bearings and to this shaft I fix a lever having a weight at end and so arranged that
its vibratory travel shifts a lever having forks to engage with the belts.
weighted lever can be set so that it will cause the belts to remain on the loose
pullies when the cage is at the bottom or give the cage a continuous journey up and
down as required.
This
In working, the cask or casks are rolled on to the cradle when the cage is at
bottom, and if the lift is set so that the cage rests at the bottom, the chain. wheel
is operated and the lift is started the cage then goes to the desired point the cradle
is lifted the cask rolled out and the cage then engaging with a stop on the hand
chain throws the fork lever over the reverse belt and causes the cage to descend,
the cradle assumes its normal position and goes to the bottom and stops for another
cask to be put on or takes an immediate return journey according as the stop is set
on the hand chain.

COMPLETE SPECIFICATION.
Improvements in Cask Elevators.
FREDERIC GEORGE RILEY of 256 South Lambeth Road in the County of
Surrey, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention which relates to improvements in apparatus for raising casks consists
in the employment of a cage which has either a continuous or intermittent up and
down journey given to it for carrying the casks but from which they are
automatically discharged at any desired point and in order that my invention may
be more perfectly understood I will more particularly describe same referring to
the accompanying drawings the letters of reference on which apply to corresponding
parts on all the figures.
Fig. 1, Sheet 1, is a vertical elevation.

page_text: Figs. 3 & 4, Sheet 3, are an enlarged view respectively in elevation and plan of
the bottom of the cage with the cradle on which the casks are placed.
It will be seen that I employ an ordinary hoist provided with a cage A and
counterbalance B which are operated by means of two belts travelling in reverse
directions over fast & loose pullies C, C and C2, on the shaft D, provided with a
worm D', the latter engaging with the worm wheel E keyed on the main shaft E'
carrying the wheel E2 over which is passed either a chain or rope to which is
secured at one end the cage A and at the other the counterbalance B.
This
Attached to the bottom of the cage A is the cradle F, to carry the cask or casks,
which is so shaped that it or they are always central when placed on same.
cradle is hinged on one side out of the centre and supported in suitable bearings
at F and below this is provided the tilting shaft G, carrying the cranks G¹ to raise
one side of the cradle. This shaft G is prolonged beyond the cage at one or both
sides and has the lever H secured on the prolonged side which engages with the
stop secured to the main frames which form the guides for the cage.
When the cage has arrived at the desired point the lever H is depressed by the
stop I and the cradle is tilted causing the cask to be thrown out.
In order to give the cage an automatic travel I provide an endless chain J,
passing over a loose pulley J¹ secured near the ground and carried through the cage
and the other end over a chain wheel J2 fixed on a rocking shaft in suitable
bearings J and to this shaft I fix a lever J which has an adjustable weight at end.
This lever in its vibratory travel shifts the rod J carrying the forks J for shifting
the belts on and off the fixed pulley C, motion to this chain being given by the
stops M, M engaging with a suitable projection on the cage; the stop M causing
the cage to descend and the stop M' causing it to ascend.
The lever J can be set so that the cage stops either at top or bottom of its
stroke or so that it works continuously up and down.
In working, the cask or casks, are rolled on to the cradle F when the cage A is
at the bottom and if the lift is set so that the cage rests at the bottom, the chain J
is operated and the belt is thrown on to the fixed pulley C and the cage rises, when it
comes to the desired point the cradle F is lifted and the cask rolls out, the cage
then engages with the stop M which throws the fork lever over and the reverse
belt on to the fixed pulley and the cage descends, the cradle assuming its normal
position; on arriving at the bottom it rests until another cask is put on or if the
stop M¹ is set for the purpose on the hand chain J the cage re-ascends of its
own accord.
It is obvious that by altering the position of the stop I the cage can be caused
to discharge casks at the bottom of its travel and by providing a second cage and
cradle in place of the counterbalance one cage can be employed to raise casks and
the other to lower at the same time, or both can be used to raise, or both to lower
according to requirement.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that what I
claim is―
1. In appliances for raising or lowering casks the employment of a cage from
which the cask or casks are automatically discharged.
2. The construction of a lift for raising or lowering casks in which the casks are
automatically discharged as described and shewn in the accompanying Specification
and drawings.
