DAVID FOSTER, of Sheffield, in the West Riding of the County of York. "Iм-
PROVEMENTS IN SELF-ACTING TILTING APPARATUS FOR BARRELS, CASKS, AND THE
LIKE ARTICLES."
This Invention relates to self-acting apparatus for tilting or raising barrels, casks,
and the like, so that their contents can be drawn off clear and free from sediment.
This Invention consists in the employment of an apparatus constructed and used
substantially as herein after specified.
The apparatus consists of an outer tube or frame, in which is one or more springs
of a helical or other suitable form; through the said spring is passed a screwed or
chased rod or inner tube, the said rod having a moveable or fixed head, shoulder, or
nut, which acts on the spring to deflect or depress it; the said rod works freely
through the end of the tube or frame, and has, working thereon, a hand wheel, by
which the rod can be raised or lowered, and the spring deflected or released. The
end of the rod can be connected to the ceiling over the barrel, and the end of the
outer tube or frame can be connected to the barrel, or vice versa, and when so
connected and properly set, the barrel will be tilted gradually as the contents are
withdrawn, owing to the elastic force of the spring acting on the rod, and by these
means the contents of the barrel can be withdrawn clear and free from sediment.

DAVID FOSTER, of Sheffield, in the West Riding of the County of York.
PROVEMENTS IN SELF-ACTING TILTING APPARATUS FOR BARRELS, CASKS, AND THE
LIKE ARTICLES."
This Invention relates to self-acting apparatus for tilting barrels containing liquids,
by which the contents of the barrel can be drawn off without disturbing any
sediment which may have collected in the under part of the barrel.
In the accompanying Sheet of Drawings,―
Fig. 1 and Fig. 2 show an apparatus constructed according to the principles of my
Invention, in which E is a spiral spring; G, the case; D, is the top cap; D¹, the bottom
cap; A, the top hook; F, the bottoni hook; B, the screwed bolt; C, the hand wheel.
Fig. 1 shows the apparatus in elevation, the case G and caps D and D' being in
section, the spring being closed, and the apparatus being ready to be attached to
the barrel.
Fig. 2 shows an elevation of the apparatus with the case G and caps D, D', in
section, the spring being open as it would be after it has expended its elastic force
in lifting or tilting the barrel as shewn in outside elevation in Fig. 4.
In Fig. 3 and Fig. 4 is shewn the above-described apparatus fixed and in use.
The apparatus can be suspended from a bar fixed over the barrel or from a staple
driven into a wall. In fixing the apparatus to the barrel, the hand wheel is turned
from left to right, which raises the screwed bolt and closes the spring (as shewn in
Fig. 1). The hook F is then attached to the back of the barrel, and the hook A to
the bar overhead, and the hand wheel C is then turned from right to left, until it is
at the top of the screwed bolt B, as shown in Fig. 3; the spring in the case will
then be exerting its elastic force to lift up the back end of the barrel, the spring
being made of such a strength as that it will only commence to lift the barrel when
about three-fourths of its contents has been drawn off. In taking off the apparatus,
the above-described operation will be reversed.
Fig. 4 shows the barrel lifted or tilted to its greatest height by the force of the
spring, and the barrel can then be entirely emptied without disturbing the sediment
therein.
This Invention can be carried into effect by constructing the apparatus with a
conical or other convenient form of spring, instead of a spiral or helical spring as
above specified, but by preference a spiral or helical spring is employed, and in
using the apparatus, it can be attached to the upper or under part of the barrel.
Having now clearly described and particularly ascertained the nature of my said
Invention, and specified in what manner the same is to be or may be performed
and carried into practical effect, I claim as novel and original, and secured to me by
the hercin-before in part recited Lotters Patent,—
Improvements in self-acting apparatus for tilting casks, barrels, and the like
articles, constructed substantially in the manner and for the purpose as herein-
before specified and described, and illustrated in Figs. 1 to Fig. 4 of the accompany-
ing Sheet of Drawings.
In witness whereof, I, the said David Foster, have hereunto set my hand
and seal, this Tenth day of October, in the year of our Lord One
thousand eight lundred and seventy-eight
