COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus for Building Up or Putting.
Together Staves for Making Casks or Barrels and the like.
I, CHARLES ELIS BRATT, of Norrlandsgatan 47, Stockholm, in the Kingdom of
Sweden, Merchant, 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 relates to machinery or apparatus for building up or putting
together staves for making casks or barrels and the like.
In the accompanying drawings:-
Figure 1 is a plan,
Figure 2 is a vertical longitudinal section on the line x, x, Figures 1 and 3, and
Figure 3 is a transverse section on the line y, y, Figures 1 and 2, showing my.
improved building-up or putting-together machine.
Figures 4 and 5 are sectional views drawn to a greatly enlarged scale showing
details of construction hereinafter described.
Like letters indicate corresponding parts throughout the drawings.
a is the frame of the machine which is provided with bearings f¹, f¹ for
supporting the driving shaft c upon which is keyed or otherwise secured a driving
pulley b. m, m2 are discs or heads having annular grooves m³, m at or near the
edges of their inner faces for receiving the staves, the said grooves forming nearly
but not quite complete circles, and suitable gaps or openings being provided at the
commencement of the said grooves for the admission of the said staves, and stops,
which latter may be formed by the termination of the said grooves or otherwise
for stopping at the required point the stave first entering the grooves during the
building up of the body as hereinafter described. 9', 9 are standards having
vertical grooves 1, 12 wherein the discs or heads m³, m² are adjustably mounted by
means of bolts, 1. The standard g' is firmly secured to the bed or frame a by.
means of bolts or otherwise, and the standard g2 is so mounted, by means of
T-bolts g, g sliding in grooves h', h in the frame, as to be free to move
lengthwise, or to and from the standard g', so as to adjust the distance between:
the grooved discs or heads m¹, m2 and adapt the machine for dealing with staves.
of different lengths. is a lever pivoted at i¹ to a block adjustable upon the bed
or frame a, and having a crank arm or projection 3 connected or coupled as shown:
at 1, to the sliding standard g, and by means of which the latter can be moved
away from the standard g when it is desired to release the built-up body.
The staves to form the body are placed upon a table which consists of parallel

page_text: bars n', n³, n³, a resting upon cross beams », a' the latter of which is attached to-
legs or supports nº. The cross-piece o' is arranged to move to and fro along the
upper side of the above mentioned parallel bars and is guided by screws or
bolts o, o, o sliding in grooves o, o formed in the said bars a, a, and by a
guiding-piece or slide o² supported between the latter so as to prevent any lateral
or vertical movement of the said cross-piece o. p is a cord, wire, or its
equivalent one end of which is attached to the rear end of the slide o by means of
a screw p. This cord or wire is passed over a roller p³ and carries at its other
end a weight pl by means of which the cross-piece o' is automatically drawn back
after each completed forward motion as hereinafter described. To the foremost
end of the slide piece o² is secured one end of another cord, wire, or its
equivalent p the other end of which is attached to a roller e mounted loosely upon
the driving shaft c.
being
and are guides for receiving the ends of the staves, that marked
attached to the bar n by means of hinges s' and s2, as shown more clearly in the
detail view Figure 5, so that it can be opened or thrown back to admit of the
insertion of staves, and that marked being firmly secured to the bar n'.
d is a clutch by means of which rotary motion can be imparted when required
to the roller e from the driving shaft c. q is a lever pivoted at 9 to a cross-
piece on the bars 2, n³. The said lever q operates the to-and-fro movements
of the clutch d, through a pin g' working in a circumferential groove in the latter
in the usual manner. q' is a latch or trigger pivoted at right angles to the cross-
piece o This-latch or trigger g' is operated at the termination of the inward
movement of the said cross-piece o by an inclined-surface.upon a block or piece
fixed to one end of the bar n³, so as to maintain the last stave in position, as-is
shown in the detail view Figure 4. is a stop attached, to the cross piece .
g is an arm or projection on the coupling lever g. The stop operates the
arm q' to throw the clutch d' out of gear when the complete body has been built
up or assembled between the discs or heads m', m²..
The operation of the machine is as follows:-
A suitable number of staves are first placed edge to edge on the table between
the guides and in front of the cross-piece of, and a truss hoop, which may be
similar to that described in the Specification of former Letters Patent granted to
me No. 3487 of 1894 is placed upon one of the grooved discs. The lever g' is
then operated by hand so as to throw the clutch, d into gear and thereby cause the
roller e to rotate and wind up thereon the cord or wire p, which latter in its turn
pulls the cross-piece of forward and with it the whole set of staves, so that the ends
The
of the staves enter the guiding grooves m³, m in the discs or heads m', m².
stave which last enters and completes the body is pressed upwards by the latch or
trigger owing to the latter running up the inclined surface upon the block gas
shown in Figure 4. Simultaneously, or nearly so, with the completion of the body,
the stopper strikes the arm q of the clutch lever, whereby the clutch d is
disengaged or thrown out of gear from the roller e; the latter being then free to
rotate upon the shaft e, the weight pl draws the cross-piece of backwards to its
original position, shown in Figure 1, and so prepares the table for the reception of
another set of staves.
The truss boop is then brought to the middle of the cask and drawn together or
tightened so that the said hoop will closely embrace the exterior of the said cask
and hold the staves in position. The lever is operated so that the sliding
standard and disc or head m³ will be moved away from the cask, and the latter
left free to be removed by means of the truss hoop, and passed on to the hooping
machine.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, I declare that what
claim is
1. In a machine for building up or putting together staves for making casks o

page_text: barrels and the like, the combination, with discs or heads having grooves into
which the staves are fed to form the built-up body, of a latch or trigger carried
upon a movable piece that forces the staves forward, and a stationary block or
piece baving an inclined surface with which the said latch or trigger comes into.
contact, whereby the last stave to be moved forward is maintained in position
substantially as set forth.
2. In a machine for building up or putting together staves for making casks or
barrels and the like, the combination of discs or heads having grooves each
provided with a stop, a table upon which the staves are placed edge to edge,
guides for receiving the ends of the staves, a movable cross-piece or other means
whereby the staves are forced into the grooves, and a latch or trigger located on
the said cross-piece or its equivalent and stationary block with inclined surface for
maintaining the last stave in position, substantially as set forth.
3. The construction, arrangement, and combination of parts constituting my
improved machine for building up or putting together staves for making casks or
barrels and the like substantially as described with reference to the accompanying
drawings.
