1, WILLIAM LLOYD WISE of No. 46 Lincoln's Inn Fields, in the County of
Middlesex, Consulting Engineer and Patent Agent, do hereby declare the nature
of this invention to be as follows:-
This invention relates to apparatus for drawing together with a -moderate
expenditure of power, the staves, already suitably cut and treated, which are
intended to form a barrel, and for giving the proper shape to the barrel by reason
of the curvature imparted to the staves.
In the accompanying drawings,
Fig. 1 is a side elevation and
Fig. 2 is a plan of apparatus according to this invention.
carried a
Figs. 3 to 5 are detail views hereinafter more particularly referred to.
The apparatus comprises a cast iron bearing or check L in which
rotary spindle S which is screw threaded for the greater part of its length and
which passes through a cross piece or screw-threaded nut M, that is capable of
being moved nearer to or further from the bearing L by the rotation of the spindle.
The nut is also provided with slots and gripping jaws for the end portions of the
rope S. The bearing is also similarly provided.
In the drawing the spindle S is shown as held end ways in the bearing L by
means of a screw that enters a groove O in the spindle; this pin and groove can
however be dispensed with, without interfering with the operation of the apparatus,
when it is desired that the spindle shall be removable from the bearing for the
purpose of more easy transport.
On the bearing I. there rotate two pulleys R R mounted loosely on pins Z,
(Figs. 1, 2 and 3) carried by cheeks B B that are fastened to the bearing L by
means of rivets N (Fig. 4). In the lower part of the bearing L are holes L'
corresponding or opposite to slots or holes M' in the nut M, through which is
guided the wire rope S₁ that passes over the pulleys R R. The rope S¹ can be
fixed in the holes L' and M' by means of gripping devices consisting as shown in
the drawings, of pressure screws provided with hand levers K, K¹, K, K³. The
screws, for the better preservation of the rope, do not grip the rope directly, but
through the medium of brass liners or gripping pieces B one of which is shown in
end and side views in Fig. 5.
In order to reduce friction and consequent wear of the bearing L in which the
spindle S is carried, due to the considerable end pressure of the spindle, it is
advantageous to insert in such bearing a bearing piece G of steel (Fig. 4) that is
arranged to receive the pressure of the spindle.
When using the apparatus the loop of the wire rope S' is placed over the staves
of the barrel F. Then, after the rope has been gripped in the holes of the nut M
by means of the levers K and K³, a crank handle or the like is placed upon the
squared part V of the spindle S, and by rotating the spindle S, the nut M is moved
away from the pulleys R R, whereby the loop of the rope is made smaller and the
staves are drawn together until they are in contact.
Should the nut M arrive at the end of the spindle before the barrel has received
its proper shape, that is to say before the staves come in contact, then in such case
the wire rope is gripped fast in the spindle bearing L, the gripping screws of the

page_text: nut M are loosened, and the nut M is screwed back again in order by again pulling
the rope to draw the staves completely together.
The apparatus hereinabove described may be used for barrels of various
kinds and sizes, because the embracing loop of the rope can be widened to any
desired extent. The holes in the spindle bearing and in the nut M can be made of
sufficient size to enable ropes of various thicknesses to be employed according to
requirement.

Improved Apparatus for Bending or Trussing Barrel Staves to Form
Barrels.
A communication from GEORG SCHEFFER, of Lowenstrasse, Zurich, Switzerland,
Merchant.
1, WILLIAM LLOYD WISE of No. 46 Lincoln's Inn Fields in the County of
London, Consulting Engineer and Patent Agent, 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:-
This invention relates to apparatus for drawing together, with a moderate
expenditure of power, the staves, already suitably cut and treated, which are
intended to form a barrel, and for giving the proper shape to the barrel by reason
of the curvature imparted to the staves.
Referring to the drawings filed with my Provisional Specification
Fig. 1 is a side elevation and
Fig. 2 is a plan of apparatus according to this invention.
Figs. 3 to 5 are detail views hereinafter more particularly referred to.
The apparatus comprises a cast iron bearing or cheek L in which is carried a
rotary spindle S which is screw threaded for the greater part of its length and
which passes through a cross piece or a screw threaded nut M, that is capable of
being moved nearer to or further from the bearing L by the rotation of the spindle.
The nut is also provided with slots and gripping jaws for the end portions of the
rope S. The bearing L is also similarly provided.
In the drawing the spindle S is shewn as held endways in the bearing L by
means of a screw that enters a groove in the spindle: this pin and groove can
however be dispensed with, without interfering with the operation of the apparatus,
when it is desired that the spindle shall be removable from the bearing for the
purpose of more easy transport.
On the bearing L there rotate two pulleys R R mounted loosely on pins Z,
(Figs. 1, 2 and 3) carried by checks B B that are fastened to the bearing L by
means of rivets N (Fig. 4). In the lower part of the bearing L are holes L¹
corresponding or opposite to slots or holes M¹ in the nut M, through which is
guided the wire rope S₁ that passes over the pulleys R R. The rope S₁ can be
fixed in the holes Land M' by means of gripping devices consisting as shewn in
the drawings of pressure screws provided with hand levers K, K' K², K³. The
screws, for the better preservation of the rope, do not grip the rope directly, but
through the medium of brass liners or gripping pieces B one of which is shewn in
end and side views in Fig. 5.
In order to reduce friction and consequent wear of the bearing L in which the
spindle S is carried, due to the considerable end pressure of the spindle, it is
advantageous to insert in such bearing a bearing piece G of steel (Fig. 4) that is
arranged to receive the pressure of the spindle.
When using the apparatus, the loop of the wire rope S' is placed over the staves
of the barrel F. Then, after the rope has been gripped in the holes of the nut M

page_text: by means of the levers K' and K', a crank handle or the like is placed upon the
squared part V of the spindle S, and by rotating the spindle S, the nut M is moved
away from the pulleys R R, whereby the loop of the rope is made smaller and the
staves are drawn together until they are in contact. Should the nut M arrive at
the end of the spindle before the barrel has received its proper shape, that is to say
before the staves come in contact, then in such case the wire rope is gripped fast
in the spindle bearing L the gripping screws of the nut M are loosened, and the
nut M is screwed back again in order by again pulling the rope to draw the staves
completely together.
The apparatus hereinabove described may be used for barrels of various kinds
and sizes, because the embracing loop of the rope can be widened to any desired
extent. The holes in the spindle bearing and in the nut M can be made of
sufficient size to enable ropes of various thicknesses to be employed according to
requirement.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. Apparatus for bending barrel staves to form barrels, comprising a stationary
guide or bearing adapted to be placed against the periphery of the annular row of
barrel staves set up to form a barrel, two pulleys R over which runs a rope S¹
which is formed as a loop to surround the row of barrel staves, and a cross piece M
capable of adjustment in relation to the said guide or bearing, through which the
ends of the rope can be drawn, and in which the said ends can be gripped fast
substantially as herein described.
2. An apparatus of the kind referred to in the preceding claim, in which the
guide or bearing provided with a gripping device whereby the rope after being
pulled tight can be held fast whilst the cross piece is adjusted into position to effect
a further pulling of the rope substantially as herein described.
Dated this 28th day of January 1892.
