Improvements in Machinery for Cutting Cask Staves and the like.
Year: 1899

page_text: I, AXEL WELIN, of 24 & 25, Fenchurch Street, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates, to a machine by which staves and the like can be
fashioned of different lengths and sizes.
The staves are cut, planed and fed between rotary cutters governed by pattern
surfaces in the ordinary way.
According to this invention the pattern surfaces consist of a pair of hoops
one on each side of a wheel and pivotted to it about diameters. This wheel is
fixed on a horizontal shaft and is caused to rotate by the stave as it passes
through the machine. The amount of bellying or the inclination of the sides
of the staves is varied by turning the hoops about their pivots.
The wheel and hoops perform a complete revolution for each stave whatever
its length being turned at first by the stave and afterwards by a weighted arm
fixed to the shaft. Momentum carries the arm beyond its lowest point and at
the end of the revolution it passes a catch which supports it in a raised posi-
tion its weight holding the wheel stationary with the pattern hoops in the proper
position for the entrance of the next stave. The arm is adjustably fixed by
friction or otherwise to the shaft so that the wheel and hoops can be turned
relatively to it and the initial position of the hoops suitably adjusted for
staves of different lengths.
Whilst the staves are being bellied their centre line is prevented from shift-
ing laterally by passing them between a pair or pairs of rollers, the spindles
of the rollers of each pair working in bearings carried by a pair of levers
pivotted at one end and having their other ends connected by links to a block
free to move in a longitudinal guide. The block is acted on by a spring causing
the rollers to always nip the sides of the stave and allowing the rollers to move
inwards and outwards to and from the centre line simultaneously but not
separately.

Improvements in Machinery for Cutting Cask Staves and the like.
I, AXEL WELIN, of 24 & 25, Fenchurch Street, in the City of London,
Engineer, do hereby declare the nature of this invention and in what manner
[Price 8d.]

page_text: the same is to be performed to be particularly described and ascertained in and
by the following statement:-
-
This invention relates to a machine by which staves and the like can be
fashioned of different lengths and sizes.
The staves are cut, planed and fed between rotary cutters governed by pattern
surfaces in the ordinary way.
Figure 1 is an end elevation (partly in section), Figure 2 is a side elevation
and Figure 3 is a plan of one end of a stave cutting machine constructed
according to this invention.
According to this invention the pattern. surfaces consist of a pair of hoops a
one on each side of a wheel and pivotted to it at a about diameters. This
wheel is fixed on a horizontal shaft and is caused to rotate by the stave cas
it passes through the machine. The amount of bellying or the inclination of
the sides of the staves is varied by turning the hoops about their pivots.
This is done by means of a sleeve d secured by a set screw d to a square or
polygonal rod 62 fixed to the boss of the wheel . The sleeve d carries pins №2
engaging with inclined slots in plates a² fixed to the hoops a.
The wheel and hoops a perform a complete revolution for each stave what-
ever its length being turned at first by the stave e and afterwards by a weighted
arm e fixed to the shaft b. Momentum carries the arm e beyond its lowest
point and at the end of the revolution it passes a spring catch which supports
it in a raised position its weight holding the wheel stationary with the pattern
hoops a in the proper position for the entrance of the next stave. The arm e is
adjustably fixed by friction or otherwise to the shaft so that the wheel band
hoops can be turned relatively to it and the initial position of the hoops w
suitably adjusted for staves of different lengths.
The stave is driven forward by the wheel g (rotated by any convenient
means not shown in the drawings) and is bellied by the rotary cutters & mounted
on vertical shafts driven by belt pullies 2. The rollers bearing on the
hoops are carried by arms ji adjustably fixed to the upper bearings of the
shaft h¹ and these bearings together with the lower bearings are carried by
frames pivotted at . The frames are pressed inwards by compressed
springs so that the rollers j are always in contact with the hoops w.
Whilst the staves are being bellied their centre line is prevented from shift-
ing laterally by passing them between a pair or pairs of rollers m, the spindles
of the rollers of each pair working in bearings carried by a pair of levers
pivotted at one end and having their other ends connected by links o to a block p
free to move in a longitudinal guide. The block is acted on by a spring
causing the rollers m to always nip the sides of the stave e and allowing the
rollers to move inwards and outwards to and from the centre line simultaneously
but not separately.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is;-
-
1. The pattern surfaces consisting of pivotted hoops substantially as described.
2. The combination of a revolving weighted pattern surface and catch such
that the surface performs a complete revolution for each stave and is automati-
cally arrested ready for the next substantially as described.
3. The means for guiding the staves substantially as described.
4.. Machinery for cutting staves and the like substantially as described and
illustrated in the drawings.
