We, EDWARD COPE, Nut and Tube Manufacturer and ALFRED HOLLINGS, Manager,
of High Bank Steel Works Oppenshaw, Manchester, in the County of Lancaster do
hereby declare the nature of this invention to be as follows:-
The object is to cut with greater rapidity than heretofore, Tubes or bars of metal,
into equal lengths adapted to be made into nuts or like articles required in large
numbers and of uniform size.
Hitherto it has been the practice to cut such articles, one after the other from a
heated bar with the result that those last cut have been longer than those first cut
owing to the cooling and contraction of the tube or bar during cutting.
Now, our invention consists. First. In cutting any desired number of nuts or
articles from the tube or bar simultaneously whilst the tube or bar is from end to end
as near as need be of the same temperature.
a
Second. In carrying the first part of our invention into practice, we employ
number of rotating saws, cutters or their equivalents, secured at the required distance
apart on a rotating shaft in combination with carriers for holding and giving motion
to the tube or bar to be cut.
One convenient construction is to secure the saws on a rotating spindle and to
couple the carriers to a tube or bar by means of supporting straps or bearings. The
carriers are formed with wheels or pulleys geared with driving wheels or pulleys and
are caused with such tube or bar both to revolve and approach recede from and pass
the peripheries of the saws preferably on a curved path or the saws alone or both the
tubes or bars and saws may have the latter motions imparted to them.

in Apparatus therefor.
We EDWARD COPE Nut and Tube Manufacturer and ALFRED HOLLINGS Manager
of High Bank Steel Works Openshaw 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:
The object is to cut with greater rapidity than heretofore tubes or bars of metal
into equal lengths adapted to be made into nuts or like articles required in large
numbers and of uniform size.
Hitherto it has been the practice to cut such articles, one after the other from a
heated bar with the result that those last cut have been longer than those first cut 1
owing to the cooling and contraction of the tube or bar during cutting.
Now our invention consists First. In cutting any desired number of nuts or articles
from the tube or bar simultaneously whilst the tube or bar is from end to end as near
as need be of the same temperature.
Second. In carrying the first part of our invention into practice we employ a
number of rotating saws, cutters or their equivalents secured at the required distance
apart on a rotating shaft in combination with carriers for holding and giving motion
to the tube or bar to be cut.
One convenient construction is to secure the saws on a rotating spindle and to couple
the carriers to a tube or bar by means of supporting straps or bearings. The carriers are
formed with wheels or pulleys wheels preferred, geared with driving wheels or pulleys,
and are caused with such tube or bar both to revolve, and approach, recede from, and
pass, the peripheries of the saws preferably in a curved path or the saws alone, or
both the tubes or bars and saws may have the latter motions imparted to them.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation and fig. 2 a plan of apparatus under our invention for cutting
tubes or bars of metal into lengths, fig. 3 is a sectional view.
1 frame, 2 saw spindle carried in bearings 3 and caused to rotate by means of the
belt pulley 4. 5 circular saws separated from each other the required distance by
washers 6 and held in position on the spindle 2 by a collar 7 and nut 8. 9 tube or bar
to be cut into lengths. 10 carriers for the tube or bar, these carriers are formed
with teeth and are free to rotate within groves in the straps 11 secured to the tube 12.
The tube 12 is carried at one end in a bearing 13 and is provided at the other end
The
with a driving wheel 14 the rear portion of which fits within a bearing 15.
straps 11 are of such a width and are so disposed on the tube 12 that when the tube is
caused to rotate the said straps will pass between the saws. Within the tube 12 a
toothed wheel 17 or series of toothed wheels on a shaft 16, is or are in gear with the

page_text: toothed carriers 10 one end of the shaft 16 is carried in a bearing within the tube 12
and the other end in a bearing 18. 19 driving gear for the said shaft. 20 hand wheel
and pinion for giving motion to the wheel 14. It is practically indispensable that
the carriers 10 and wheels 17 should be geared by means of teeth so that the openings
through the carriers may always be in position to receive the tube or bar to be cut
especially so when such tubes or bars are square or hexagonal. Round bars or tubes
have motion imparted to them by frictional contact with the sides of the angular
shaped holes. The wheel 14 is made with an opening 21 shewn in fig. 4 through
which the tubes or bars to be cut are inserted into the carriers.
The action of the apparatus is as follows:-
A tube or bar is inserted through the opening 21 into the carriers whilst the said
carriers are away from the saws. The saws are caused to rotate in the direction of
the arrow, and motion is given to the shaft 16, so as to cause the carriers and with
them the tube or bar, to be cut to rotate in the direction of the arrow. The hand
wheel 20 is then turned so as to cause the tube 12 to rotate, and cause the straps and
carriers and with them the tube or bar to approach pass between and recede from
The tube or bar is thereby cut into lengths equal to the distances between
the saws.
The cut lengths are then pushed out of the carriers by the insertion therein
of another tube or bar or portion thereof.
the saws.
It will be obvious that the carriers may be moved to and from the saws in
guides or that the saws may be moved to and from the carriers.
In cutting
steel tubes or bars into lengths the metal would usually be acted on at a dull red
heat but softer metal such as brass may be operated on cold, or at a comparatively
low temperature.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is,
First. Cutting a tube or bar simultaneously into lengths substantially as set
forth.
Second. Saws carriers and driving gear in combination, for cutting tubes or bars
into lengths substantially as set forth.
