A New or Improved Appliance for Cutting Glass Tubes and Cylinders.
I, JAMES KENYON, Engineer, of 8 and 9, South Parade, Manchester, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to appliances for cutting glass tubes and cylinders.
According to our improvements we effect the cutting of the tubes or cylinders
by means of rotary cutters of which there may be one or more in each appliance
according to the general character of the cutting and of the dimensions of the work.
The cutter or cutters is or are mounted upon or near the end or ends of a rod or rods;
and the cutting is done from within the tube or cylinder, by bringing the cutter or
cutters into contact with the glass and giving the appliance or the glass or both of
them the required motion. In an appliance for cutting tubes transversely, a single
cutter may be employed mounted upon the end of a rod, which may be graduated;
the other end of the rod being joined with a parallel rod which does not enter
the tube and carries, in the plane of the cutter, an abutment which may be closed
upon the outside of the tube simultaneously with the contact of the cutter
with the glass inside the tube. This motion may be effected by causing the
parallel rods to approach each other. In an appliance for cutting glass tubes and
glass cylinders longitudinally, two cutters are mounted longitudinally on the ends of
two rods which can be separated, The rods being inserted into the tube or cylinder,
are separated so as to bring the cutters into contact with the glass, whereupon
either the appliance or the article to be cut, or both is or are moved longitudinally.
In this case the two rods may be jointed similarly to a pair of forceps.

A New or Improved Appliance for Cutting Glass Tubes and Cylinders.
I, JAMES KENYON, Engineer, of 8 and 9, South Parade, Manchester, in the
County of Lancaster, 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; -
Hannan kau sutting close tubes and cylinders.

page_text: According to our improvements I effect the cutting of the tubes or cylinders by
means of rotary cutters of which there may be one or more in each appliance
according to the general character of the cutting and of the dimensions of the
work. The cutter or cutters is or are mounted upon or near the end or ends of
a rod or rods and the cutting is done from within the tube or cylinder by bringing
the cutter or cutters into contact with the glass and giving the appliance or the
glass or both of them the required motion.
I will more fully describe my invention with reference to the accompanying
drawings, in which:-
Figure 1 represents in side elevation, and Figure 2 in end elevation, an appli-
ance for cutting the tubes or cylinders transversely.
Figure 3 shows in side elevation a similar appliance for cutting the tubes and
cylinders longitudinally, and Figure 4 a section along the line a, Figure 3.
In the form of the appliance illustrated by Figures 1 and 2, a single rotary disc
cutter C is mounted near the end of the graduated rod A. This rod is constructed
of steel or other suitable spring metal, and has a returned part constituting the
nearly parallel limb B, upon the end of which an abutment 1) is fixed. On the
limb B, a sliding handle E is mounted, which also acts as a lever fulcrumed at c.
The outer end of the handle lever E engages a link or slotted plate F which has
a boss through the eye of which the rod A. can be slided. The cutter C is mounted
with its axis in or parallel with the axis of the rod which is provided with a gradua-
tion in any convenient measure of length from the cutter as zero.
In use, the appliance is first set to cut off the required length. In the drawing
Figure 1, this is supposed to be two inches. The slotted link or plate with its
boss G, constituting also a gauge, is then fixed by the screw H and the end of the
tube or cylinder is passed over the end of the rod A until it reaches the gauge G.
The appliance being then grasped by the hand, over the handle E, the wall of the
tube or cylinder is gripped between the cutter and the abutment D. Rotary
motion being then given to either the appliance or to the tube or to both, the tube
is cut. The appliance being then withdrawn, the end of the tube may be broken
off.
In the modified form of the appliance for cutting glass tubes and glass cylinders
longitudinally, as represented by Figures 3 and 4, two rotary disc cutters CC are
mounted near the ends of the two rods A, B, the axes of the cutters being at right
angles with the axes of the rods. These two rods are pivotted at a, and are pro-
vided with handles E in the same manner as forceps, but so that when the handles
are grasped and caused to approach, the cutters will separate.
In using this form of the appliance, the rods A, B are brought close together and
are inserted into the glass tube or cylinder. The handles E are then pressed
together, thus forcing the cutters into contact with the walls of the tube or cylinder
and in this condition the appliance is pulled or pushed along as far as may be
required to cut the article operated upon. When it is desired to ensure that the
cuts shall be absolutely true, a slip of wood or other material I may be previously
inserted into the glass tube or cylinder J to act as a gauge, as indicated by
Figure 4.
I may use other cutters than the rotary disc cutters described, diamonds for
example, but I prefer to employ the well known steel discs, because they are quite
effective for the purpose and because they are much cheaper. It will be obvious
also that I may modify the construction and arrangement of the appliances in
various ways. For example, the modified appliance shown by Figure 3 may,
with slight alterations, be used for cutting the tubes and cylinders transversely.
For this purpose the cutters are mounted in the rods at right angles to the position
shown and herein before described, and a gauge equivalent to the gauge G,
Figures 1 and 2, may be mounted upon one of the rods A or B. This modification
may be further modified by substituting one of the rotary cutters by a simple
roller.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
Appliances for cutting glass tubes and cylinders, constructed substantially as
hereinbefore described with reference to the accompanying drawings.
