PROVISIONAL SPECIFICATION.
Improvements in connection with the Manufacture of Seamless.
Metallic Tubes..
I, CHARLES THOMAS BROCK SANGSTER, Works Manager of The Cycle Components
Manufacturing Company Limited, of Bournbrook, near the City of Birmingham,
do hereby declare the nature of this invention to be as follows :-
This invention relates to means for piercing the tagged ends of tubes prior to the
same being rolled or drawn.
Thus, solid drawn or rolled tubes, are, at their forward ends, gathered spike wise
for the purpose of admitting of the same being introduced into the passes of the dies
or rolls, which gathering in is technically known as "tagging." Now when such
forward ends are complotely closed by the tagging process, it is necessary that the
same should be pierced in order to admit of the escape of pent-up air when the tubes
are introduced into the cleaning, pickling and oiling baths.
This piercing, which is generally done in a transverse direction, is usually done by
lads who drive a spike through the hollow part of the tag when in a heated and soft
state.
My invention has for its object, the simplification of this piercing process, and
consists in the employment of a rising and falling or an advancing and retiring
spiking tool, carried within a suitable holder or block working upon a guide or within
or between guides and operated by a cam, excentric or other like motion taken from
off a foot or hand lever.
The workman, after the tag has been formed, has only to place the end of the
tube under the piercing tool and place his hand or foot upon the lever when the said
tool descends or drops and penetrates a hollow part of the tag and immediately retires
by the cam, excentric, crank or other motion or a spring giving a return movement
to the same on the workman taking foot. or hand. from the lever.
I wish it to be understood that I do not confine myself to the means herein
described for actuating the piercing tool, as the same may be made self-acting and to
come into operation during the process of tagging the end.

Improvements in connection with the Manufacture of Seamless
Metallic Tubes..
I, CHARLES THOMAS BROCK SANGSTER, Works Manager of The Cycle Components
Manufacturing Company Limited, of Bournbrook, near the City of Birmingham,
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:
This invention relates to means for piercing the tagged ends of tubes prior to the same
being rolled or drawn.

page_text: Thus, solid drawn or rolled tubes are, at their forward ends, gathered spikewise
for the purpose of admitting of the same being introduced into the passes of the dies
or rolls, which gathering in is technically known as "tagging."
Now when such
forward ends are completely closed by the tagging process, it is necessary that the
same should be pierced in order to admit of the escape of pent-up air when the tubes
are introduced into the cleaning, pickling and oiling baths.
This piercing, which is generally done in a transverse direction, is usually done by
lads who drive a spike through the hollow part of the tag when in a heated and soft
state.
My invention has for its object, the simplification of this piercing process, and
consists in the employment of a rising and falling or an advancing and retiring
spiking tool, carried within a suitable holder or block working upon a guide or within
or between guides and operated by a cam, excentric or other like motion taken from
off a rotating shaft or from off a foot or hand lever.
The workman, after the tag has been formed, has only to place the end of the
tube under the piercing tool and place his hand or foot upon the lever when the said
tool descends or drops and penetrates a hollow part of the tag and immediately retires
by the cam, excentric, crank or other motion or a spring giving a return movement
to the same on the workman taking foot or hand from the lever.
Figure 1 represents an unpierced tagged end of a tube in elevation.
Figure 2 represents a pierced tagged end of a tube in elevation.
Figure 3 represents the said pierced tagged end in section.
Figure 4 represents a machine such as may be employed for the piercing operation.
a is the tagged end of a tube a, and a is the piercing thereof, for the purpose as
herein set forth.
In Figure 4, b is a piercing tool, carried by a holder or carrier b¹, fitted to a
slide 6, working within guides 6, of an upright frame 64, having an overhead
shaft b, with an excentric or crank 66, with a strap having a forked rod 6º, whose
lower end is jointedly connected to the said slide b. c is a face plate or crank
with a stud c', to which a connecting rod e² is connected at a lower end to an arm or
lever c³, made fast to an axle c, counterpoised by a weight c', (or drawn back by a
spring) and operated by a foot lever c³.
If necessary the piercing apparatus may be operated by power or by a band taken
around the pulley d.
e is a bed, e¹ the rest, with a set e² and e³ is a stripper.
It is only necessary for the workman to place his foot upon the lever co, after
placing the end of the tag in the set e, and then bring his foot down, when the
piercing tool descends, pierces a hole in the walls of the tag, when the workman
takes his foot from the foot lever, and the parts of the piercing apparatus are
automatically taken back to their normal positions, and the piercing tool removed from
the tag by the said tag being drawn up to and stopped by the stripper.
I wish it to be understood that I do not confine myself to the means herein
described for actuating the piercing tool, as the same may be made self-acting and to
come into operation during the process of tagging the end.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. Piercing the tagged ends of metallic tubes by a raising and falling piercing
tool, sliding within guides and operated by the foot or like means, substantially as
described and set forth.
Secondly. In piercing the tagged ends of metallic tubes, by a rising and falling
piercing tool, sliding within guides and put into action through the medium of
an excentric or crank operated by foot, hand or power, substantially as described
and set forth.
Thirdly. In piercing the tagged ends of metallic tubes, by a rising and falling
piercing tool, sliding within guides and put into action through the medium of an

substantially as described and set forth.
