Improved Barrel Tilter.
We WILLIAM SIMPSON, SYDNEY SMART, and ROBERT SKIRROW, all of No. 165
Sussex Street, Salford in the county of Lancaster, Ironfounders and Machine Makers,
trading in copartnership under the style of The Simpson Patent Selvage Motion
Company do hereby declare the nature of this invention to be as follows:-
Our said invention relates to apparatus for automatically tilting or elevating one
end of a barrel as the liquid contained therein is gradually drawn off.
In our said invention we avail ourselves of the property which spiral springs
possess when in a state of tension of being able to exert a greater or less pull in
proportion to the extent to which they are stretched.
In a frame which may be hung on a wall or secured in any convenient position we
so arrange a lever that one end which hereinafter we refer to as the lifting end shall
project over the end of the barrel in connection with which our said invention is
intended to be used. Between the fulcrum of the said lever and the lifting end a
spiral spring is connected to the lever. The other end of the spring is secured to
the frame of the apparatus and the whole is arranged in such a manner that the spiral
spring is in tension when the lifting end of the lever is connected to the end of the
barrel by means of a chain or other suitable means and continually tends to lift the
barrel. When the barrel is full the lifting end of the lever is drawn down to its lowest
position and the spiral spring will then exert its greatest pull. The pulling force of
the spring is so adjusted that it is equal to the weight the lever has to lift. By this
means as the weight diminishes owing to the liquid being drawn off, the end of the
barrel is lifted, but inasmuch as the force of the spring diminishes as it contracts
equilibrium is being continually restored between the lifting power and the weight to
be lifted and in this manner the barrel is tilted automatically and without sudden
shocks. In order to readily adjust the pulling force of the spring to suit barrels of
various weights we provide means for varying the distance of the lower end of the
spring from the fulcrum of the lever and in order to adjust the vertical distance
through which the end of the barrel may be elevated we also provide means for readily
varying the position at the lifting end of the lever of the connection between the lever
and the barrel.
Instead of a single spiral spring we may for convenience employ two or more such
springs acting conjointly on the lever, and instead of varying their point of con-
nection with the lever for the purpose of adjusting the lifting force we may employ
independent accessory springs or sliding weights.

COMPLETE SPECIFICATION.
Improved Barrel Tilter.
We WILLIAM SIMPSON, SYDNEY SMART, and ROBERT SKIRROW, all of Number 165
Sussex Street Salford in the County of Lancaster, Ironfounders and Machine Makers,
do hereby declare the nature of our invention for "IMPROVED BARREL TILTER
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement and accompanying drawings
:-
Our said invention relates to apparatus used for the purpose of automatically
tilting or elevating one end of a barrel as the liquid contained therein is drawn off.
In our said invention we avail ourselves of the property which spiral springs
possess when in a state of tension of being able to exert a greater or less pull in
proportion to the extent to which they are stretched.

page_text: In order that our said invention may be more fully understood we have annexed
hereunto a sheet of drawings in which Figure 2 is a plan with the cover plate
removed to show the interior mechanism and Fig. 1 is a sectional elevation
throughy of the plan. The same letters refer to the same parts in both figures.
The framework of the apparatus consists of two side plates a a, a front plate b pro-
vided with a slot through which the lifting lever A may project, and a cover
plate C serving to strengthen and keep rigid the whole structure. Various methods
of supporting or suspending the apparatus may be adopted, as for instance the side
plates may be provided with hooks d for the purpose of hanging the apparatus on a
bar e held in suitable supports close to the wall. When arranged in this manner the
back of the lower edge of each side plate will abut against the wall as at a¹ Fig. 1.
A shaft B whose journals are supported by the side plates a a carries the lifting
lever A to the outer end of which is attached a chain or other connection, between the
end of the barrel and the lifting lever. By means of holes or a sliding piece on the
lever A the chain can be attached to the lever A at any desired point. Rigidly
mounted on the shaft A are two levers c c provided with notches in which fit cross
bars D D. Corresponding notches are formed in the side plates a a to receive the
cross bars E E. The ends of one or more spiral springs E¹ E¹ are attached to the
crossbars D D and E E. A toothed wheel F is also mounted on the shaft A in which
a detent or pawl G may be caused to gear when required for the purpose of preventing
the rising of the lever A.
To use the apparatus the lever A is pulled down to its lowest position as shown in
Fig. 1. The pawl G is brought into gear with the tooth wheel and the chain is
secured to the end of the full barrel to be tilted. The pawl G is then removed.
Supposing the pulling force of the springs is carefully adjusted to the weight of the
barrel when full the end of the barrel will be raised as the weight diminishes when the
liquid is drawn off but inasmuch as the pulling force exercised by the springs
diminishes as they contract equilibrium is being continually restored between the
lifting power and the weight to be lifted. In this manner the barrel is tilted auto-
matically and without sudden shocks. The notches in the levers c c enable the cross
bars D D to be placed at varying distances from the centre of rotation of the levers
for the purpose of augmenting or diminishing the effective pull of the springs to suit
barrels of different weights. A sliding weight on the lever A or accessory springs
acting in a contrary direction to that of the springs E' E' might be used for the same
purpose.
Although we find it more convenient to attach the springs to the separate levers c c
secured to the same shaft as the lifting lever A the springs can also be attached directly
to the lever A.
By providing additional notches as indicated at a² the springs may be stretched to a
still greater extent for the purpose of varying their pulling force.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. In a barrel tilter the use of a lever A in combination with one or more spiral
springs E' acting directly thereon or on one or more levers attached to the same axis
substantially as herein before described.
2. The use combination and arrangement of the lever A, one or more levers cc
secured to the same axis, one or more springs E' secured at one end to the levers c
and at the other end to the framework, with means for adjusting the places of attach-
ment of the springs, and the tooth wheel F with a pawl G the whole acting
substantially as and for the purpose hereinbefore described and shown.
