Improvements in Machines for Glazing and Sizing Tubes of Paper
and other Material.
We, JAMES GEORGE ACCLES, of Perry Barr, near Birmingham, in the County
of Warwick, and JAMES PINFOLD, of No. 233 Park Road, Aston, in the County of
Warwick, Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to machines for reducing to standard size and for glazing
or polishing tubes of paper and other material and the said invention is intended
chiefly for treating the paper tubes or cases of sporting and other cartridges.
An important feature of the said invention is the employment of a revolving
and reciprocating die through which the tubes are successively passed.
Another important feature of our invention is the use of a rotary dial plate with
mandrels to receive the tubes to be treated and to bring them successively and
automatically to the position where they can enter the die.
A still further novel feature of our invention is the employment of extractors
for automatically removing the tubes from the mandrels after they have been
passed through the die.
Our improved machine comprises a suitable frame furnished with vertical guides
upon which a cross bar carrying the die or dies can slide. This cross bar is recipro-
cated by means of connecting rods and cranks from the driving shaft of the
machine. The spindle for rotating the die moves up and down with the die, being
constructed to slide through its driving pulley to which it is connected by a feather
key. The spindle is hollow and encloses a rod or tube which is connected by pillars
to the cross bar that carries the die and which therefore moves up and down with
the die. The said rod or tube is furnished at its lower end with spring like hooked
extractors that serve to remove the paper or other tube from the mandrel during
the upward movement of the die. On the table of the machine is a rotary dial
plate furnished with a series of mandrels arranged in a circle upon which mandrel;
the tubes to be treated are placed by hand. The plate is rotated intermittently
by a cam or pawl or other suitable mechanism to bring the mandrels successively
beneath the die.
We preferably employ several narrow dies locked together in a box rather than
one thick die, and we keep them cool by wet cotton waste or the like placed in a
chamber surrounding the dies box, the waste being kept moist by water allowed to
drip into it.
In some instances we dispense with the dial plate and employ one stationary
mandrel.

Improvements in Machines for Glazing and Sizing Tubes of Paper
and other Material.
We, JAMES GEORGE ACCLES, of Perry Barr, near Birmingham, in the County
of Warwick, and JAMES P'INFOLD, of No. 233 Park Road, Aston, in the County
Warwick, Engineers, do hereby declare the nature of this invention and in wha
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to machines for reducing tubes of paper and other
material to a standard size and for glazing or polishing such tubes and the said
invention is intended chiefly for treating the paper tubes or cases of sporting and
other cartridges.
An important feature of the said invention is the employment of a revolving and
reciprocating die for operating upon the tubes.
Another important feature of our invention is the use of a rotary plate furnished
with mandrels which receive the tubes to be treated and which bring the tubes
successively and automatically to the position where the die can pass over them.
A still further novel feature of our invention is the employment of an extractor
for automatically removing the tubes from the mandrels after the die has passed
over them.
Referring to the accompanying drawings which illustrate convenient modes of
carrying our invention into practice.
Figure 1 is a front elevation,
Figure 2 is a side elevation, and
Figure 3 is a plan of a machine with several mandrels constructed according to
our invention.
Figure 4 is a front elevation of a modified form of machine having one mandrel
only.
Figure 5 is a vertical central section on an enlarged scale of the extractor, the
die and its driving shaft and gearing, and
Figure 6 is a vertical central section of the upper end of the driving shaft and
bearing, the driving pulley and the extractor tube.
Like letters of reference denote corresponding parts throughout the drawings.
A is the frame of the machine; B, B are vertical guides; C is a cross bar adapted
to slide up and down on said guides; D, D are connecting rods and D', Dare
disc cranks by which the cross bar C is reciprocated. The cranks D' are fixed on a
shaft E which is driven by gear wheels F, from the main driving shaft G. H is
the die for sizing and glazing the tubes. Preferably the die is made up of a num-
ber of steel rings h mounted in a box J which is secured to the lower end of the
die spindle K. The rings h are loose in the box J so as to be capable of a slight
lateral movement whereby they can adjust themselves to the tubes. They are
caused to rotate with the box J by means of keys J' which are secured in the box
and which project into slots provided in the edges of the rings. Preferably two
keys are employed as shown. The spindle K is connected to the cross bar C by
means of a collar K¹ and lock nuts K so that it moves up and down with the said
cross bar. Its driving pulley L however does not move up and down being
supported in a stationary bracket M fixed to the frame of the machine. The con-
nection of the pulley to the shaft is effected by a feather key L' which works in a
long slot or keyway k in the shaft and allows the shaft to slide through its driving
pulley and bearing. The spindle is driven by a belt L2 from a shaft L³ which is
driven by a belt L from the main driving shaft G. L³, L5 are guide pulleys for

page_text: the belt L. The spindle K is hollow and encloses a tube N which is connected by,
a cross head N¹ and pillars 0, 0 to the cross bar C and which therefore moves up
and down with the said cross bar. The said tube N is furnished at its lower end
with a spring hook N which is curved to extend more or less around the tube
and which serves as hereinafter described to remove the paper or other tube from
the mandrel during the upward movement of the cross bar C.
On the table of the machine shown in Figures 1 to 3 is a rotary pivoted
plate Q furnished with a series of vertical mandrels Q arranged in a circle and
formed with shoulders Q upon which the ends of the tubes rest.
The tubes to be sized and glazed are placed on the said mandrels by hand and
are successively brought under the die by an intermittent rotary movement of the
plate Q which is actuated as follows. That is to say, on the shaft E is fixed a
cam R which engages with a pin carried by a lever S pivoted at St and operates to
oscillate the said lever to and fro once during each revolution. The upper end
of the lever is connected to a slide $2 which carries a pawl S3 that engages with
notches in the edge of the plate Q and moves the plate intermittently through an
angle corresponding to the distance between the mandrels.
The action of the machine is as follows, the tubes to be treated having been
placed on the mandrels Q the machine is started and the rapidly rotating die is
caused to descend and pass over the tube on the mandrel which is in line with it
thus sizing and glazing the tube. The descent of the die continues until the
hooked end of the extractor N2 passes below the end of the tube and then the
ascent begins and during such movement the extractor draws the tube from off
the mandrel. The rotary plate Q is then moved round to bring another mandrel
under the die whereupon the die descends again and operates upon
the next tube, and the operation thus continue, the denuded mandrels being
supplied by hand with fresh tubes as they come to the front of the machine. It
will be understood that the finished tubes are gradually pushed up the extractor
tube and are delivered at the top.
To keep the dies cool we employ wet cotton waste or the like placed in a case 'T
that surrounds the die box J. Water is allowed to continually drip on to the
waste.
The modified machine shown in Figure 4 has one mandrel only which remains
stationary and in this case means are provided to stop the machine to afford time
for placing the tubes on the mandrel. For this purpose we arrange the gear
wheel loosely on its shaft E and we provide a key V controlled by a spring V₁
for locking the wheel to the shaft to allow of rotating the latter. The key is
formed with a head V2 the face of which at cach revolution of the shaft comes in
contact with and slides along the inclined face of a wedge W which operates to
withdraw the key from engagement with the wheel and so releases the shaft which
immediately stops, the die being then in the raised position. When it is desired
to re-start the machine, the wedge W which may be hung loosely on the driving.
shaft G is raised by a foot treadle W acting through a link W pivoted arm or
lever W, and link W. As soon as the key is released by the raising of the
wedge W the spring operates to push it into engagement again with the
wheel F and the shaft is rotated once more. So long as the operator keeps his
foot on the treadle W the machine will continue working, but immediately he
removes his foot the treadle is raised by a spring W and the wedge is thus lowered
to the position in which it will operate to draw back the key V.
It is obvious that we may vary the details of construction of the above described
machines without departing from the spirit of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. In a machine for glazing and sizing paper and like tubes the revolving and
reciprocating die substantially as, and for the purpose, specified.

page_text: 2. The combination, with the revolving and reciprocating die, of the inter-
mittently rotating plate furnished with mandrels for receiving the tubes, substan-
tially as, and for the purpose, described.
3. In a machine of the kind herein described the extractor for removing the
tubes from the mandrels, constructed and operating substantially as set forth.
4. The machine constructed as described with reference to either of the forms
illustrated in the accompanying drawings, and operating as, and for the purposes
specified
