"
IMPROVED SELF-FEEDING AND AUTOMATIC MACHINE OR APPARATUS FOR THE
PURPOSES OF PUNCHING, PERFORATING OR INDENTING, AND SHEARING OR CUTTING
to be as follows:-
My invention consists in improvements upon the devices described and illustrated
by me in the specification of my invention bearing date the 17th February, 1879,
Number 771. The punching devices according to that invention are not adapted
to operate upon plates, but upon thin strips of comparatively narrow width.
Whereas in the automatic self-feeding device or apparatus according to my present
invention I am enabled to punch plates and bars such as are used by iron ship-
builders, bridge and girder manufacturers, gasometer and gas meter makers, safe
makers, coppersmiths and others requiring to punch, perforate, indent or stamp
plates and bars. According to my invention also, provision is made for performing
the operation of cutting or shearing.
In the apparatus according to my present invention, in order to ensure the
automatic action of the punching tool and the self-feeding of the metal or other
material under treatment I adopt a combination of working parts of which the
following is a general description of what I find to be a convenient arrangement,
and which I prefer to employ. That is to say-I mount on the driving end of a
spindle working through the hollow head of the machine a toothed wheel which
gears into a corresponding toothed wheel mounted on the corresponding end of a
lower spindle, both said spindles working in suitable bearings. At the operating
end of the lower spindle is fitted a mitre wheel working into another carried upon
a vertical spindle mounted upon the framing of the machine. At the top of the
latter mitre wheel is mounted a disc with a sliding pin fitted in dovetails regulated
by a screw passing through the V part of the pin and secured at each side of the
dise for the purpose of regulating the pin to any desired stroke on the disc. To
the said sliding pin is adapted a connecting rod one end thereof being attached to
the pin and the other to a short horizontal slide piece at the top of which is

page_text: mounted a catch piece or detent. The said catch piece or detent has imparted to
it a compound movement, namely in a reciprocating horizontal direction and of a
vibratory movement in a horizontal plane.
In the front of the machine is mounted a bed carried on suitable supports. To
the upper surface of the said bed, and working in V shaped recesses formed therein
is a sliding table piece to which the plate to be operated upon is fixed. At the
edge of the said operating table is fitted a rack into which takes the before
mentioned detent, so as to advance the table with the plate thereon, to the required
distance beneath the operating tool.
For the purpose of punching, bars, I adapt two removeable slide pieces at each
end of the machine, which slide pieces when the operation of punching bars is
being performed project above the edge of the table and are provided with gripping
pieces to allow of the bar being carried underneath the centre of the punching tool.
Also, by a suitable alteration in the form of the punching tool, the apparatus
according to my invention may be utilized for punching out the teeth of web
saws. It is also designed and constructed to allow of holes or indentations of any
shape being formed at any desired distance apart. It is entirely self-acting, and

of my improved machine the necessity for marking out holes in the plates to be

operation of a regulating screw moved to a graduated rule index.
The apparatus according to my present invention is also adapted to be used for
shearing or cutting (though not self-actingly) by forming the upper end of the
vertically sliding tool block as the moveable member of a pair of cutting shears.

operation of punching being done at one side of the machine and the shearing at
the other.

page_text: I JAMES TOSHAW of 5 Osborn Place, Whitechapel, London, E in the County of
Middlesex, Engineer, do hereby declare the nature of my Invention for AN
IMPROVED SELF-FEEDING AND AUTOMATIC MACHINE OR APPARATUS FOR THE
PURPOSES OF PUNCHING, PERFORATING OR INDENTING, AND SHEARING OR CUTTING,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement and accompanying sheet of
Drawings:-
:-
My present invention consists in improvements upon the devices described and
illustrated in the Specification of my Invention bearing date the 17th February,
1882, No 771. The devices according to that invention are not adapted for
operating upon plates but upon thin strips of comparatively narrow width and
especially hoop iron such as used by Packing Case Makers and others. Whereas,
in the automatic punching and self-feeding devices comprised in the apparatus or
machine according to my present invention, I am enabled to operate upon plates;
of greater thickness and instead of upon mere strips as in the case of my Patent
No 7718 and, such for instance, as are used by iron-ship builders, bridge and
girder makers, gasometer and gas meter makers, safe makers, coppersmiths and
others requiring to punch, perforate, indent or stamp metal plates or sheets. I also
nake provision in my present invention for performing the operation of cutting or
shearing.
In the accompanying sheet of drawings illustrative of my present invention,
Figure 1 is a plan view thereof; Figure 2 a front elevational view; and, Figure 3
a side elevational view thereof. Figures 4 to 10 inclusive are detached views
appended for the purpose of allowing to be more easily distinguished, the details of
the self-feeding and automatic punching devices forming the essential features in
this my present invention.-The same letters of reference are used throughout the
several Figures to denote like parts in each.
In accordance with my present invention, in order to ensure the automatic
action of the punching tool and the self-feeding of the metal or other substance
under treatment, I adopt a combination of working parts or mechanism of which
the following is a general description of what I find in practice to be a convenient
arrangement and which I prefer to employ. That is to say:-I mount on the
driving end of a spindle or shaft a,—working through the hollow head b of the
machine, a toothed wheel c gearing into the corresponding toothed wheel d
mounted on the end of the lower spindle e; both said spindles or shafts a and e
working in suitable bearings.-At the operating end of the lower spindle e is fitted
a mitre wheel f working into another mitre wheel g carried upon a vertical
spindle mounted upon the framing of the machine. At the top of the mitre wheel g
is mounted a disc with a sliding pin i (see more particularly Figures 7 and 8) the
lower part of which is fitted in dovetails j formed in the disc h; said sliding
pin being regulated by a screw k passing through the lower or V part of i, and
secured at each side of the disc h, for the purpose of adjusting the pin to any
desired stroke on the disc. To the sliding pin i is adapted a connecting rod m
one end thereof being attached to the pin i and the other, to a short horizontal
slide piece n, at the top of which is mounted a catch piece or detent o (Figure 6)
which latter has imparted to it a compound movement, namely in a reciprocating
horizontal direction, and of a vibratory movement in a horizontal plane. This is
produced by the wheel & being formed at with a segmental cam piece, which on
the rotation of the wheel d, is brought in contact with the slide piece d", the other

page_text: end of which works against the detent o. o' is a spring which serves, when the
slide du retires from contact with d¹ (namely while the punching tool in its
downward stroke is acting upon the metal in forming the holes) to force back the
detento against the slide d out of gear with the teeth of the rack s.
In front of the machine is mounted a bed p carried on suitable supports q. To
the upper surface of said bed and working in V shaped recesses formed therein, is
a sliding table to which the plate to be operated upon is secured by tightening-up
nuts or their equivalents. At the edge of said operating table is fitted the racks,
into which takes the before mentioned detent o with spring o¹; so as, on the
machine being started, to advance the table, with the plate thereon, to the required
distance beneath the operating tool. By suitable alterations in the shape of the
latter, the apparatus, according to my present invention may also be utilised for
punching out the teeth of web saws and for other applications; retaining always,
the special feature of my said invention as herein before set forth and hereinafter
claimed.
The apparatus according to my present invention is also applicable to be used
for shearing or cutting (though not self-actingly) by forming the upper end of the
vertically reciprocating tool block as the moveable member 2 of a pair of cutting
shears 1, 2. If however the shearing or cutting operation be required to be done
self-actingly, a duplication of the operating head of the machine and of the table
arrangement herein before described, in front thereof, would be necessary, so as to
allow of the operation of punching being done at one side of the machine, and the
shearing at the other.
The apparatus or machine according to my present invention is also adaptable to
be used for punching holes or indentations of any desired shape or at any desired
distance apart. It may also be arranged to punch one, two, three, or more holes at
a time. By the use of said machine or apparatus, the necessity for marking out
holes in the plates to be punched, as also for "holding up " and the consequent
outlay for labor on the same are avoided. As, the plate to be punched, is simply
placed on the operating table and secured thereto as hereinbefore described, so as
to be immediately brought into position ready to be acted upon continuously by
the self-feeding and automatic punching mechanisms or devices herein-before
described and set forth. Said machine or apparatus being adjustable, readily, to
any punching distance, by the arrangement of the regulating screw hereinbefore
described, moved to a graduated scale index (the latter is not shewn in the
accompanying drawings.)
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
1 claim is:
Firstly: The combined machine or apparatus generally as herein described and
set forth and shewn in Figures 1 to 3 inclusive of the accompanying sheet of
drawings.
Secondly-The special mechanisms or devices employed for ensuring the
combined automatic punching and self-feeding operations forming the essential
features of my present invention (as distinguished from that included in my prior
Patent No 771) as herein described and set forth, and illustrated more particularly
in the detached views Figures 4 to 10 inclusive, of the accompanying sheet of
drawings.
