page_text: LETTERS PATENT to Arthur Henry Bateman, of East Greenwich, in the County
of Kent, Engineer, and John Snowdon, of Franklin Road, New Brompton, in
the County of Kent, for the Invention of "IMPROVEMENTS CONNECTED WITH
VERTICAL PUNCHING MACHINES, WHEREBY THEY CAN BE CONVERTED AT WILL
TO HORIZONTAL PUNCHING MACHINES.' "
PROVISIONAL SPECIFICATION left by the said Arthur Henry Bateman and
John Snowdon at the Office of the Commissioners of Patents on the 30th June
1879,
ARTHUR HENRY BATEMAN, of East Greenwich, in the County of Kent, Engineer,
and JOHN SNOWDON, of Franklin Road, New Brompton, in the County of Kent.
"IMPROVEMENTS CONNECTED WITH VERTICAL PUNCHING MACHINES, WHEREBY THEY
CAN BE CONVERTED AT WILL TO HORIZONTAL PUNCHING MACHINES."
This Invention relates to improvements connected with vertical punching
machines, whereby they can be converted at will to horizontal punching machines.
In carrying our Invention into effect we temporarily bolt to the base of an
ordinary vertical punching machine a casting of suitable shape which carries a die,
and on or in which we form a guide to receive a sliding piece.
The inner end of this sliding piece is formed with an inclined plane, with or
without two or more friction rollers, and the outer end with a socket to receive the
punch, which is removed from its ordinary position in the machine as a vertical
punch and transferred to the outer end of the said horizontal sliding piece.
A block is now fitted in the position previously occupied by the vertical punch,
the lower end of the said block being formed with an inclined plane and passing
through a hole in the top of the guide to take against the corresponding inclined
plane on the inner end of the before mentioned horizontal slide.
The inner face of the lower end of the vertical blocks bears against the inner
end of the guide and is thus supported in its work when the machine is in use.
The action of the inclined plane of the vertical block upon the corresponding
plane of the horizontal sliding piece forces this latter outward and effects the
punching operation. The return of the punch is effected by means of one or more
link pieces, a pin or projection on one end of each of which takes into a hole in the
horizontal slide, the other end of each of such link pieces being provided with
another projection to take into an inclined slot or groove in the vertical block and
thus draw the horizontal slide and punch inwards after each punching operation,
when said block partakes of its upward motion.

the said Arthur Henry Bateman and John Snowdon in the Great Seal Patent
Office on the 30th December 1879.

"IMPROVEMENTS CONNECTED WITH VERTICAL PUNCHING MACHINES, WHEREBY THEY
CAN BE CONVERTED AT WILL TO HORIZONTAL PUNCHING MACHINES."
This Invention relates to improvements connected with vertical punching
machines, whereby they can be converted at will to horizontal punching machines.
The manner in which we carry our Invention into effect will be clearly under-
stood by the following description with reference to the annexed Drawings:-
Figure 1 is a side view, Figure 2 an end view, and the remaining Figures show
detail portions of the Invention.
We temporarily bolt to the base a of an ordinary vertical punching machine a
casting b of suitable shape, which carries a die c, and on or in which we form a
guided to receive a sliding piece 6.
The inner end of this sliding piece e is formed with an inclined plane f (with or
without 2 or more friction rollers) and the outer end with a socket g to receive the
punch h, which is removed from its ordinary position in the machine as a vertical
punch and transferred to the outer end of the said horizontal sliding piece e. A 1
block i is now fitted in the position previously occupied by the vertical punch, the
lower end of the said block being formed with an inclined plane j and passing
through a hole k in the top of the guide d to take against the corresponding
inclined plane fon the inner end of the before mentioned horizontal slide e.
The inner face of the lower end of the vertical block i bears against the inner
end of the guido d (as seen in Figure 1), and is thus supported in its work when
the machine is in use.
The action of the inclined planej of the vertical block i upon the corresponding
plane of the horizontal sliding piece e forces this latter outwards and effects the
punching operation.
The return of the punch is effected by means of one or more link pieces m, a pin
or projection on one end of each of which takes into a hole o in the horizontal
slide e, the other end of each of such link pieces being provided with another
projection p to take into an inclined slot or groove g in the vertical block i, and
thus draw the horizontal slide e and punch inwards after each punching operation,
when said block partakes of its upward motion.
And having now described the nature of our said Invention and in what manner
the same is to be performed, we declare that we claim,-
3
The improvements connected with vertical punching machines whereby they can
be converted at will to horizontal punching machines, as hereinbefore described and 4
substantially as shown in the annexed Drawings.
In witness whereof, I, the said Arthur Henry Bateman, for myself and on
behalf of the said John Snowdon, have hereunto set my hand and seal, this
Twenty ninth day of December, One thousand eight hundred and seventy
nine,
ARTHUR H. BATEMAN. (L.S.)
