An Improved Machine for Marking Articles of Iron or other
Material.
I, ROBERT BLACKWELL HANSELL of 58 Fenchurch Street in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to mark stamp or impress any word or combination
of letters, trade mark or any other signs on iron steel or other materials, the common
practice to attain this purpose is to strike with a hammer a piece of steel on the
opposite end to that upon which the raised design or inscription has been previously
prepared. The resulting impression is frequently imperfect sometimes it is impressed
deep at one part or only faint or eligible at another or the whole may be at an angle
instead of being straight, this is the effect of the amount of force employed or the
position of the blow or the particular way in which the mark may have been held it
is therefore difficult and requires practice to get a uniform impression from one of
these marks ospecially if it is of an unusual length, some experience is also needed to
design a good mark whereby the blow may be balanced by the position and quantity
of matter to be impressed by the mark or stamp, the said mark or stamp is some-
times fixed into a fly press or similar machine, this machine doing the work of a
hammer.
The object of this invention is to produce on materials of various dimensions, a
straight clear legible mark of any desired uniform depth throughout its entire length.
And for this purpose I make use of a machine, described by referring to the accom-
panying drawing-Y Y are legs upon which rests a bed II carrying a sliding bed J
this bed is operated through the rack and pinion K W by means of the handle L
above the bed J the vertical standards H H carry the slide N in the centre of which
is attached the revolving stamp Z this slide N N can be raised or lowered by means
of the hand wheel M which lengthens or shortens the screw Q which works in a
sleeve this sleeve carries a plate S upon which works the cam or eccentric T
operated by the lever U the small set screw V controls the distance travelled by the
lever U the spring R R sustains the slide &c. and keep up all close to the cam T
resting on S. X is a plate to support the standards.
The mode of operation is as follows:-The article to be stamped is fixed by means
of such suitable contrivance as its particular form may require so as to bring the
surface to be marked to a uniform level, then by means of the hand wheel M the
mark Z is brought on to or nearly touching the article, the lever U is brought
down through its limited travel, the first portion of the mark has then been impressed
afterwards by means of the handle L the table J travels forward the mark Z revolves
and impresses the inscription it carries or such portion as may be desired, the lever U
is then raised releasing the mark and immediately the article is free.
There are several modifications which it is apparent to adopt, for instance the bed J
might be actuated by other means, further the machine can be made open at the
side and making one standard sufficiently strong-in place of the cam T a screw of
coarse thread with a weight nut could be put on, but these are all so cumbersome,
that the cam and set screw appear to supply and control that additional impressive
power after the mark has been placed in a convenient and useful position to
receive it.

An Improved Machine for Marking Articles of Iron or other
Material.
1, ROBERT BLACKWELL HANSELL of 58 Fenchurch Street in the City of London
Engineer, 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 of this invention is to mark stamp or impress any word or combination
of letters, trade mark or any other signs on iron steel or other materials. The common
practice to attain this purpose is to strike with a hammer a piece of steel on the
opposite end to that upon which the raised design or inscription has been previously
prepared. The resulting impression is frequently imperfect, sometimes it is impressed
deep at one part or only faint or illegible at another or the whole may be at an angle
instead of being straight. This is the effect of the amount of force employed or the
position of the blow or the particular way in which the mark may have been held
it is therefore difficult and requires practice to get a uniform impression from one of
these marks especially if it is of an unusual length. Some experience is also needed
to design a good mark whereby the blow may be balanced by the position and
quantity of matter to be impressed by the mark or stamp. The said mark or stamp
is sometimes fixed into a fly press or similar machine, this machine doing the work
of a hammer.
The object of this invention is to produce on materials of various dimensions, a
straight clear legible mark of any desired uniform depth throughout its entire length.
And for this purpose, I make use of a machine, described by referring to the
drawings left with the provisional specification. One of these drawings is a side
elevation and the other is a front elevation of a machine made in accordance with
my invention. Y Y are legs upon which rests a bed II carrying a sliding bed J
this bed is operated through the rack and pinion, K, W by means of the handle L
which is fast upon the axis of the pinion. This axis is carried in bearings in the
bed J. Above the bed J the vertical standards H H carry the slide N in the centre
of which is attached the revolving stamp Z this slide N N can be raised or lowered
by means of the hand wheel M which lengthens or shortens the screw Q which works
in a sleeve Q which is fitted into a socket in the head of the machine in which
socket it can move longitudinally. The screw Q has a head at its lower end beneath
the hand wheel and this is received into a recess in the slide N and is retained by
a cover plate fixed on the slide as the drawing shows. The sleeve Q' carries a plate Š
upon which works the cam or eccentric T operated by the lever U. When the lever
handle U is drawn down the stamp is forcibly depressed by the short distance required
to produce the impression the small set screw V controls the distance travelled by
the lever U the spring R R sustains the slide &c. and keep up all close to the cain T
resting on S. X is a plate to support the standards.
The revolving stamp or mark Z is a wheel or part of a wheel of hardened steel
having the mark to be impressed in relief or intaglio upon its periphery.. A pin also
of hard steel on which the stamp or mark revolves passes through a central hole.
The pin is inserted into a passage formed for it in the slide, N and is then held by
small locking screw or in other convenient way or the pin is controlled by a returning
spring so as to bring the mark back to its former indicated position.
a
The mode of operation is as follows:-The article to be stamped is fixed on the
bed by means of such suitable contrivance as its particular form may require so as
to bring the surface to be marked to a uniform level, then by means of the hand
wheel M the mark Z is brought onto or nearly touching the article. The lever U is
now brought down through its limited travel. The first portion of the mark has
then been impressed. Afterwards by means of the handle L the table J is made to
travel forward, the mark Z revolves and impresses the inscription the mark or stamp
carries or such portion as may be desired. The lever U is then raised releasing the
mark and immediately the article is free.

page_text: There are several modifications which it is apparent to adopt; for instance the
bed J might be actuated by other means, further the machine can be made open at
the side, making one standard sufficiently strong. In place of the cam T a screw of
course thread with a weight nut could be put on, but these are all cumbersome; the
cam and set screw appear suitable to supply and control the additional impressive
power required after the mark has been placed in a convenient position to receive it.
For the marking of rods and bars and such like I dispense with the sliding bed J,
and substitute for it a wheel on the periphery of which the rod or bar to be marked
rests. The axis of this wheel which is directly under the revolving stamp or mark
can be turned by means of a lever handle or it may be geared with another axis on
the bed I which can be turned by a handle or driven by power. Guide rollers may
also be provided on the bed I to aid in controlling the rod or bar whilst the mark is
being impressed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is
1. A marking machine in which the following parts are combined; a sliding bed
or travelling support for the article to be marked; a circular revolving stamp or mark
of hard metal having the device to be impressed in relief upon its periphery, a slide
carrying the said stamp or mark so that the same is adjustable to and from the bed or
support and mechanism for forcing and holding the slide with the stamp or mark
up to the article whilst the same is upon the bed or support and is caused to travel
past the said stamp or mark.
2. A marking machine substantially as herein described.
