WALTER E. CRANE, OF EL PASO, TEXAS, ASSIGNOR TO THE POLLARD-
ALLING MANUFACTURING COMPANY, OF NEW YORK, N. Y., A COR-
PORATION OF NEW JERSEY.
MACHINE FOR SHEARING OR CUTTING METAL.
SPECIFICATION forming part of Letters Patent No. 685,743, dated November 5,1901.
Application filed 'October 27, 1900. Serial No. 34,581, (No model.)To all who721 it m ay concern:
3e it known that I, WALTER E.CRANE,a citi-
zen of the United States, residing in El Paso,
in the county of El Paso and State of Texas,
5 have invented certain new and useful Im-
provements in Machines for Shearing or Cut-
ting Metal, of which the following is a specifi-
cation.
My invention relates to an apparatus for
io shearing or cutting metal, and is primarily
designed for use in connection with a plant
embodying means for uniting the ends of me-
tallic sheets to form a continuous strip having
type-impressions to be employed with what
15 are known as " addressing - machines " for
printing the mailing directions upon blanks
to be applied to newspapers, &c.
With this end in view the object of my in-
vention is the provision of a metal shearing
20 or cutting machine which will sever from
the continuous strip on predetermined lines
blanks containing the names or addresses of
subscribers whose subscriptions have ex-
pired and will also sever from other sheets
25 of the same material blanks containing ad-
dresses that it is desired to substitute for
those withdrawn from said strip. This metal
shearing or cutting machine is provided with
a punch or die which cooperates with a com-
30 plementary die in the bed-plate of the ma-
chine and produces on the ends of the strip a
notched dovetail - joint formation adapted
either to be united with the original continu-
ous strip after the addresses have been re-
35 moved therefrom or to be joined to blanks
containing new addresses, as above set forth.
A further object of the invention is to pro-
videan improved construction of metal shear-
ing or cutting machine, all as hereinafter de-
4o scribed.
Referring to the accompanying drawings,
Figure 1 is a side elevation of a plant includ-
ing this improved cutting-machine looking
toward the left in Fig. 3. Fig. 2 is a plan view
45 of a part of the soldering-machine which may
be employed. Fig. 3 is a front elevation of such
plant, showing the metal shearing or cutting
machine and a soldering-machine located side
by side on the same table. Fig. 4 is a sectionon line a a, Fig. 3, looking in the direction of 50
the arrow and representing in side elevation
the shearing or cutting machine. Fig. 5 is a
plan view of said shearing or cutting ma-
chine. Fig. 6 is a plan view of a printing
strip or sheet representing the notched dove- 55
tail-joint connection formed therein by the
shearing or cutting machine when severing
the same. Fig. 7isa transverse longitudinal
section of the improved shearing-machine,
parts of the same being shown in elevation. Go
Fig. 8 is a plan view of the bed-die of the
shearing-machine and of a clamp for holding
the sheet-metal strip thereon. Figs. 9 and
10 are sectional details illustrating the shear-
ing-dies and the strippers cooperating there- 65
with. Fig. 11 is a perspective view of one of
the shearing-dies, showing the teeth or pro-
jections thereon which cooperate with simi-
larly-shaped openings in the lower die and a
stripper - plate applied to the side of said 70
shearing-die.
Referring to the drawings, in which like
characters designate like parts throughout the
several views, the numeral 1 designates a post
or pillar having a flange at its top, to which 75
the bed-plate 2 of the plant is attached in any
suitable manner. Mounted on this bed-plate
is a metal shearing or cutting machine, (des-
ignated in a general way by 3,) which will
now be described. This machine, as shown, 8o
embodies a frame 4, to which the various op-
erative parts and the bed-die 5 are connected,
and pivoted to a standard 6 of said frame is
a head 7, carrying the upper die 8 of the ma-
chine. Connected to studs or projections 9 85
9' on each side of said head are links 10 10',
articulated at their lower ends to cranks or
wrist-pins 11 11', which are operated by a le-
ver 12, having a pivot 13, to which a pitman
or rod 14, leading to a suitable treadle 15, is 90
attached. Die 8, carried by head 7, is pro-
vided on its working face with a series of
punches or projections 16, which conform to
the series of openings 17 in the lower die 5,
and at one side of said die 8 is a stripper- 95
plate 18, operating in a manner hereinafter
set forth, a similar stripper-plate 19 being
movable at the side of said lower die 5.
