We, WILLIAM WILLIAMS of Maesygwernen Hall, and Upper Forest Tin
Plate Works, Tin Plate Manufacturer, and WILLIAM GUNTHORPE MORRIS
of 43 Crown Street, Mechanical Engineer, both of Morriston, R.S.O. in the
County of Glamorgan, do hereby declare the nature of our said invention to be as
follows:-
This invention relates to a new or improved machine for re-squaring black plates,
tin plates, terne plates, and the like, also any other plates or sheets made of iron
or steel, or any other material, and consists of suitable framework provided with
bearings in which is mounted a shaft or centre. On the shaft or centre are
mounted rotating arms to which are attached blades or knives for cutting or
re-squaring black plates, tin plates, terne plates, and the like, also any other plates
or sheets made of iron or steel, or any other material placed upon the receiving
table. The framework of the machine is provided with stationary projections or
arms to which are attached blades or knives, which in conjunction with the rotating
knives or blades re-square or cut the black plates, tin plates, terne plates, and the
like, also any other plates or sheets made of iron or steel or any other material,
when lifted by the latter from the receiving table. The latter is secured to the
framework of the machine in any convenient manner and consists of framework
provided with supports on which the plates to be treated are placed and are so
disposed as to allow of the rotating arms carrying the blades or knives passing
through the same. Between the aforesaid rotating arms are fixed any number of
supports according to the width of the machine, the supporting or receiving table
being provided with openings to allow of the passage of same." The base plate of
the machine is so constructed that the distance between the side frames, which are
provided with right and left hand screws may be altered to suit the width of
materials to be operated upon.
The shaft or centre carrying the rotating arms may be provided with a chain
wheel or other mechanical means for driving the same from any convenient source.
Automatic arrangements, such as levers and the like, are provided on the delivery
side of the machine for carrying or tipping the plates operated upon to a trolly
to save handling, thus saving labor and expense. Each side is so constructed so as
to cut or square one or both ends of material operated upon.

We WILLIAM WILLIAMS of Maesygwernen Hall, and Upper Forest Tin
Plate Works, Tin Plate Manufacturer, and WILLIAM GUNTHORPE MORRIS
of 43 Crown Street, Mechanical Engineer, both. of Morriston, R.S.O. in the
County of Glamorgan, 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 and accompanying drawings:-
This invention relates to a new or improved machine for re-squaring and paring
black plates, tin plates, terne plates, and the like, also any other plates or sheets
made of iron, steel, or any other material.
The apparatus consists of suitable framework provided with bearings in which is
mounted a shaft or centre carrying rotating arms to which are attached blades or
knives for cutting or re-squaring the plates which are placed upon a receiving
table. The framework of the machine is provided with stationary projections or
arms to which are attached blades or knives, which in conjunction with the rotating
knives or blades re-square or cut the plates when lifted by the latter from the
receiving table. The table is secured to the framework of the machine in any
convenient manner and consists of a framework provided with supports on which
the plates to be treated are placed and are so disposed as to allow of the rotating
arms carrying the blades or knives passing through the same. Between the
aforesaid rotating arms on the shaft are fixed any number of supports according to
the width of the machine, the supporting or receiving table being provided with
openings to allow of the passage of the saine.
The base plate of the machine is so constructed that the distance between the
side frames may be altered to suit the width of materials to be operated upon.
The shaft or centre carrying the rotating arms may be provided with a chain
wheel or other mechanical means for driving the same from any convenient source.
Automatic arrangements such as levers and the like are provided on the delivery
side of the machine for carrying or tipping the plates operated upon, to a trolly to
save handling, thus saving labor and expense. Each side is so constructed as to cut
or square one or both ends of the material operated upon.
The invention will be more fully understood by a reference to the annexed sheet
of illustrative drawings.
Fig. 1 is a side elevation of the apparatus.
Fig. 2 is a plan.
Fig. 3 is a vertical section.
Fig. 4 is an end view.
Fig. 5 shows the movable and fixed blades and arms in contact.
The apparatus is composed of two side frames a a which are supported upon and
bolted to a sole b, and held apart by stays c provision being made to set the
frames a at the desired distance apart corresponding to the width or length of plate
to be operated upon.
A shaft d is carried in suitable bearings in the frames a and is rotated from a
chain wheel e or by any other suitable means. Upon the shaft d we key two double
levers or arms f and we also fix between the arms two or any other suitable number
of supporting fingers lying in the same plane as the arms. The result is that
when the shaft d is revolved in the direction indicated by the arrows the arms and
fingers are carried round therewith. Upon the arms f we fix shear blades / secured

The apparatus is composed of two side frames a a which are supported upon and
bolted to a sole b, and held apart by stays c provision being made to set the
frames a at the desired distance apart corresponding to the width or length of plate
to be operated upon.
A shaft d is carried in suitable bearings in the frames a and is rotated from a
chain wheel e or by any other suitable means. Upon the shaft d we key two double
levers or arms and we also fix between the arms two or any other suitable number
of supporting fingers lying in the same plane as the arms. The result is that
when the shaft d is revolved in the direction indicated by the arrows the arms and
fingers are carried round therewith. Upon the arms f we fix shear blades / secured
by means of bolts i. The frames a also carry fixed arms ; projecting at the
indicated angle and furnished with shear blades k like the movable arms, the shear

page_text: blades h, k being set relatively to each other as appears in Fig. 4 so that when
they pass each other in the relatively indicated direction, the plate / would be cut
off at that point.
On that end of the machine to which the plates are fed we bolt or fix a table m
with gaps therein to allow the arms or blades f h and also the fingers g to pass in
revolving. On one side of the machine we also fix a fence n. When the machine
is at work, the plates to be trimmed, cut or squared are placed upon the table m,
the fence adjusting them to the proper position end wise while the edge of the plate
lying against the bosses f¹ of the arms f is kept straight thereby. The arms and
fingers f g are meanwhile revolving and passing through the gaps in the table m,
lift the plate and carry it round till the projecting edges encounter the fixed
blades whereupon the shearing action of the blades h cuts off the plate at both
ends and exactly at right angles to the inner edge. The squared or trimmed plate
is then carried further forward and dropped upon receiving fingers or levers or
upon a trolly or other automatic removing means devised to save handling. The
said removing means is however no part of our invention and we need not therefore
describe such means. The arms are revolved at such a speed as to allow the
plates to be placed properly on the table m so that the work goes on continuously.
The plates might be cut or trimmed at both ends as described or they might be
cut at one end only.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. The general arrangement, construction and combination of the improved
apparatus for squaring, cutting and trimming thin sheet metal plates substantially
as described and shown.
2. As means for squaring, cutting and trimming thin sheet metal plates the
revolving arms carried on a central shaft and furnished with shear blades acting
in conjunction with fixed shear blades attached to the framework of the machine
substantially as described and shown.
3. The improved apparatus for the indicated purposes consisting of the revolving
and fixed shear blades blade carriers in combination with the carrying table to
receive the plates and made with gaps to allow of the passage of the movable arms
and blades and supporting fingers and a fence for the adjustment of the plates
all arranged and operating substantially as herein before described and shown.
