"IMPROVEMENTS IN MACHINES FOR MAKING CERTAIN KINDS OF CASKS OR
BARRELS."
My Invention relates to machines for making cylindrical casks or barrels used
for packing sugar, fruit, flour, cement, and other articles of merchandise. These
barrels are made of one or more layers of broad thin sheets or staves bent to the
form of the barrel, and the machines for making them as at present constructed
consist of a revolving drum or former, on which the sheets or staves are bent; a
pressure roller with guides for the hooping bands, by which the sheets or staves
are bent to the shape of the drum, and circular saws, for cutting the barrel to a
uniform length. The pressure roller is mounted in fixed bearings, and it has
grooves turned in it to give passage to the hooping bands, and the hoop guidos are
fixed opposite these grooves. The saws also are fixed on the ends of their shaft
outside the moveable or swinging frame in which said shaft is mounted.
thus constructed a machine is only capable of making casks of one size.
As
Now the object of my improvements is to enable a single machine to be readily
adapted to make casks of different diameters and lengths, and thus avoid the
necessity of employing a number of different sizes of machines for the purpose.
According to my Invention, instead of turning the pressuro roller solid I inake
it of a rod with loose collars secured by set screws whose points are received in a
V groove cut spirally in the roller, so as to prevent the collars shifting laterally.
By loosening the set screws the collars may be readily adjusted along the roller to
suit any desired number and position of the hoops. The bearings of this pressure
roller are fitted in slotted guides, so as to make the roller adjustable to suit either
a large or small drumn or former. The bar that carries the hoop guides is moveable
is this respect with the pressure roller, and the hoop guides themselves are made
adjustable along the bar, instead of being immovably fixed thereto, so that they can
D

pressure roller. For this purpose the guide bar may be slotted, and tho guides be
secured therein by binding screws. To enable the saws to be shifted along their
spindle to any point between the spindle bearings and the belt pulley, the spindle
is screwthreaded, and the saws are fixed upon it between jam nuts and collars.
The saw spindle is mounted in a swinging frame, which is brought up towards the
barrel when the ends are to be sawed off. The saw spindle is driven by a belt
from a grooved pulley on a counter-shaft, and the saws are set in motion and
stopped by the act of swinging the saw-frame towards or away from the barrel. If
the machine be driven by hand power, stationary cutters would be used instead of 1
circular saws.
These cutters would be attached to hand levers and pressed against
the barrel whilst it is revolving against them.

of an Order of the Lord Chancellor filed by the said George Davis Terry in
the Great Seal Patent Office on the 5th February 1881.

"IMPROVEMENTS IN MACHINES FOR MAKING CERTAIN KINDS OF CASKS OR
BARRELS."
My Invention relatos to machines of the kind described in the Specification of
Letters Patent granted to Herbert John Haddan, dated January 23rd, 1879,
No. 288, for making cylindrical casks or barrels used for packing sugar, fruit, flour,
cement, and other articles of merchandise. These barrels are made of one or more
layers of broad thin sheets or staves bent to the form of the barrel, and the machines
for making them as at present constructed consist of a revolving drum or former, on
which tho sheets or staves are bent; a pressure roller with guides for the hooping
bands, by which the sheets or staves are bent to the shape of the drum, and circular
saws, for cutting the barrel to a uniform length. The pressure roller is mounted
in fixed bearings, and it has grooves turned in it to give passage to the booping
bands, and the hoop guides are fixed opposite these grooves. The saws also are fixed
on the ends of their shaft outside the movable or swinging frame in which said
shaft is mounted. As thus constructed a machine is only capable of making casks
of one size.
Now the object of my improvements is to enable a single machine to be readily
adapted to make casks of different diameters and lengths, and thus avoid the
necessity of employing a number of machines of different sizes for the purposo.
According to my Invention, instead of turning the pressure roller solid, I make it of
a rod with loose collars secured by set screws, whose points are received in seats or
in a groove cut spirally in the roller, so as to prevent the collars shifting
laterally. By loosening the set screws the collars may be readily adjusted along the

page_text: roller to suit any desired number and position of the hooops. The bearings of this
pressure roller are fitted in slotted guides so as to make the roller adjustable to
suit either a large or small drum or former. The bar that carries the hoop guides
is movable in this respect with the pressure roller, and the hoop guides themselves
are made adjustable along the bar instead of being immovably fixed thereto, so
that they can be altered in number and position to correspond with the grooves
around the pressure roller. For this purpose the guide bar may be slotted, and tho
guides be secured therein by binding scrows. To enable the saws to be shifted along
their spindle to any point between the spindle bearings and the belt pulloy, to
correspond to the length of tho cask, the spindle is screwthreaded, and the saws are
fixed upon it between jam nuts and collars. The saw spindle is mounted in a
swinging frame as usual, which is brought up towards the barrel when the ends
aro to bo sawed off, tho saw spindle being driven by a belt from a grooved pulley
on a countershaft, and the saws set in motion and stopped by the act of swinging
the saw frame towards or away from the barrel. If the machine be driven by hand
power, stationary cutters would be used instead of circular saws: These cutters
would be attached to hand levers and prossed against the barrel whilst it is
AL
DESCRIPTION OF DRAWINGS.
Figure 1 represents a portion of the adjustable pressure roller; Figuro 2
represents the hoop guide bar with adjustable hoop guides; Figure 3 represents the
saw spindle and the means of adjusting the circular saws thereon; Figure 4
represents the cutters used in lieu of circular saws; Figure 5 represents a front
elevation of part of the machine, showing the adjustable pressure roller and hoop
guides, and the hand cutters for trimming the ends of the barrel.
The samo letters of reference indicate the same parts in all the Figures. Referring
to Figure 1, the pressure roller consists of a round shaft a and pairs of loose
collars b sliding upon it and secured at any desired position by set screws c, screwing
through tapped holes in the collars, and having their points received in any of a series
of seats d drilled in the shaft a in a spiral line or in a spiral V groove cut in the
shaft, as indicated by the dotted lines. The diameter of collars b exceeds that of
the shaft a sufficiently to permit of the collars pressing upon the staves or sheetings
forming the barrel, whilst the shaft a presses upon the hooping bands passing
between the pairs of collars b. The shaft a is turned throughout and has journals
at its ends, which are received in bearings c (see Figure 5) bolted to the standards ƒ
of the machine frame.
The latter has slots through which bolts pass to admit of the bearings e being
fixed higher or lower to accommodate a larger or smaller drum or former.
Referring to Figure 2, g is the hoop guido bar, and are the adjustable hoop
guides. The bar g, instead of being drilled at intervals for fixing the hoop guides
in permanent positions as hitherto, is made broader and stronger, and has a
longitudinal slot i cut in it, and the hoop guides h are secured by wing nuts and
scrows passing through said slot, whereby they may be readily loosened and slid
along the bar to adjust them to correspond to the positions of the grooves between
the pairs of collars of the pressure roller. If the bearings e of the pressure roller
are made adjustable in height, the guide bar g would be fixed to them, so as to bo
raised and lowered with the pressure roller.
Referring to Figure 3, k is the circular saw spindle mounted in bearings 1 on the
swinging saw frame m as before; n are the saws fixed on the spindle inside
the bearings. To enable them to be shifted along the spindle as may be
required, the latter screw has a screwthread cut upon it, and the saws aro
clamped between loose collars o by means of nuts p screwing upon the
spindle k.
Referring to Figures 4 and 5, r is a round bar fixed on the uprights ƒ of the
frame, and a are hand lovers pivoted thereon between collars fixed by set screws at

page_text: any desired position, according to the length of the barrel, and t, t¹, are cutters fixed
on said levers; u is a steadying bar connecting the two levers 8, its ends being
connected to the levers by bolts passing through slots in the bar to adınit of the
lateral adjustment of the levers.
Having described the nature of my Invention, and the manner of performing
the same, I declare that what I claim as my Invention to be protected by the
herein before in part recited Letters Patent is,―
1st. In a machine for making casks, as herein described, the employment of a
pressure roller constructed of a shaft fixed with loose collars fixed adjustably
thereon, substantially as and for the purpose set forth.
2nd. In a machine for making casks as herein described, making the pressure
roller adjustable to suit a large or small drum or former, substantially as
specified.

saws upon their spindle so as to be capable of adjustment, substantially as shown
and described.
5th. The employment in a machine for making casks as herein described, of
stationary cutters fixed on laterally adjustable hand levers, arranged and applied
substantially as shown and described.
6th. The employment in combination of a pressure roller constructed with
adjustable collars and mounted in adjustable bearings, adjustable hoop guides, and
laterally, adjustable saws or cutters, substantially as herein described, the whole
_ combined with a revolving drum or former which may vary in length and diameter,
whereby a single-machine-is_adapted to make casks of different sizes, as
specified.
In witness whereof, I, the said George Davis Terry, have horeunto set my
hand and seal, this Twenty second day of December, in the year of our
Lord One thousand eight hundred and eighty.
