Improvements. in. Hand Tools for Corrugating and Cutting Pipes.
and other Articles.
I, JAMES BLUMER, residing at the corner of Crescent and Hill Streets, in the
City of Brooklyn, County of Kings, and State of New. York, United States of
America, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a combined corrugating and cutting tool for sheet metal.
This tool is adapted for use upon all kinds of sheet metal, but is especially
available for corrugating the sheet iron at the end of stove pipe joints, so as to
adapt the one end of such stove pipe joint to slip. into the plain end of the next
joint; also for cutting the stove pipe into the desired lengths, and for,,trimming the
cut ends true before,corrugating.
In my invention, I employ a stock and handles, the one rigidly connected with
the stock, and the other pivoted thereto, and a pair of corrugating, rolls, the one
roll upon a fixed arbor in the stock, and the other upon an eccentric arbor passing
through the stock.
The corrugating rolls are made, with engaging teeth, and a pawl is connected to
and operated by the moving handle for progressively rotating the corrugating, rolls,
and a spring acts to draw the pawl back and open the handles.
A cutting jaw is rigidly connected to, said, stock, and a moving cutting jaw and
integral arm are pivotted to the stock and are operated from and by a connection,
such as a link, with the moving, handle, whereby the cutting jaws are operated by
the same handles employed for operating the corrugating rolls, and the same
instrument answers for both corrugating and cutting sheet metal..
I also provide, in connection with the corrugating rolls of said tool, a device for
moving the eccentric arbor of one corrugating roll for changing the relation of the
corrugating rolls to each other, and a device for holding the eccentric arbor in the
desired position, and also, a, device, for holding the cutters, jaws and handles in a
closed condition in which the tool can be carried about in the hands, or upon the
person, without liability of injury.

Improvements in Hand Tools for Corrugating and Cutting Pipes
and other Articles.
I, JAMES BLUMER, residing at the corner of Crescent and Hill Streets, in the
City of Brooklyn, County of Kings and State of New York, United States of
America, Manufacturer, 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 :-
My invention relates to a combined corrugating, and cutting tool for sheet metal.

page_text: This tool is adapted for use upon all kinds of sheet metal but is especially
available for corrugating the sheet iron at the end of stove pipe joints so as to
adapt the one end of such stove pipe joint to slip into the plain end of the next
joint; also for cutting the stove pipe into the desired lengths and for trimming the
cut ends true before corrugating.
In my invention I employ a stock and handles, the one rigidly connected with
the stock and the other pivoted thereto, and a pair of corrugating rolls, the one
roll upon a fixed arbor in the stock and the other upon an eccentric arbor passing
through the stock.
The corrugating rolls are made with engaging teeth and a pawl is connected to
and operated by the moving handle for progressively rotating the corrugating rolls
and a spring acts to draw the pawl back and open the handles.
A cutting jaw is rigidly connected to said stock, and a moving cutting jaw and
integral arm are pivoted to the stock and are operated from and by a connection,
such as a link, with the moving handle, whereby the cutting jaws are operated by
the same handles employed for operating the corrugating rolls and the same
instrument answers for both corrugating and cutting sheet metal.
I also provide, in connection with the corrugating rolls of said tool, a device for
moving the eccentric arbor of one corrugating roll for changing the relation of the
corrugating rolls to each other, and a device for holding the eccentric arbor in the
desired position, and also a device for holding the cutters, jaws and handles in a
closed coudition, in which the tool can be carried about in the hands or upon the
person without liability of injury.
In the drawing, Fig. 1 is a side elevation representing my improved corrugating
and cutting tool and a modified form of arm. Fig. 2 is a plan view of the same.
Fig. 3 is a front elevation. Fig. 4 is a partial elevatión representing the prefer-
able form of arm and the handles and jaws as closed thereby, and Fig. 5 is a
plan of the arm shown in Fig. 4.
The stock A is provided with a handle A', and a second handle B is pivoted at 2
to the stock A. and the corrugating rolls C and D are supported upon the arbors 3
and 4 that extend out from the stock A. These corrugating rolls C and D work
together similar to gears, their diameters being reduced except at the inner ends
adjacent to the stock A, the outer portions of the rolis performing the corrugating
operation and the inner ends acting as teeth that remain in gear without the risk
of their being separated by the sheet of material that is introduced between the
teeth of the roll to be corrugated.
The handle B has a projection to which the pawl E is pivoted at 6 aud this
pawl E engages the teeth of the corrugating roll C. The pawl E is provided with
an eye, and a stud 7 projecting from the handle A', is also provided with an eye
and a contractile spring F is connected with the eyes of the pawl E and stud 7.
As the handles A' and B are brought together by the gripping action of the hand,
the pawl is thrown forward and the corrugating rolls C and D are rotated and the
contractile spring is strained. A stop block 5 on the handle B regulates the
distance of the handles from each other when closed. Upon the release of the hand
this spring contracts and opens the handles and returns the pawl to the normal
position for again rotating the corrugating rolls.
The stock. A is continued at its forward end and is notched for the reception of
a hardened cutting jaw a which is connected thereto preferably by screws, and said
stock A receives the pivot 10 of the moving cutting jaw b. This cutting jaw b has
an integral arm blat the other side of the pivot 10, and a link c is connected by
pivots 8 and 9 to the end of this arm band to the handle B, and as the handle B
is moved the cutting jaw b is operated through the medium of the link c and
descends over the cutting edge of the stationary jaw a so as to cut and separate a
sheet of metal.
The pivot 10 of the moving cutting jaw bis preferably a pin securely held in
the stock A above the arbor 3 of the corrugating roll C, and this pin or pivot 10
projects through the moving cutting jaw and is provided with a nut at the end to

page_text: hold the jaw in place. It is, however, evident that this pivot may be constructed
in any desired manner.
i'
The corrugating roll D is upon an eccentric arbor 4 which projects through the-
stock A, and to this arbor an arm is connected the movement of which operates.
the eccentric arbor to move the roll D nearer to or farther from the roll C so that
said rolls are in engagement with each other or slightly separated, and means are.
provided for maintaining this arm in the desired position. The preferable form of¨
arm is shown at I, Figs. 4 and 5, an'l this arm is made with an inwardly projecting
lug containing a cavity holding a strong helical spring shown by dotted lines,..
and which spring bears upon the surface of the hub of the stock A which surrounds
the arbor 4 to produce sufficient friction to hold the arm I in whatever position it.
may be placed. This lug when the handles A B and the cutting jaws a bare
closed and the arm I¹ is turned to the position Fig. 4 comes up beneath the lower-
edge of the arm & and acts as a stop to keep the handles and jaws closed and the
tool in a convenient and safe condition to be carried about by the workman. When
the arm is turned down the corrugating rolls C D are brought nearer together
to perform their functions.
In. Figs. 1 and 2 a modified construction of arm is shown as connected to the-
eccentric arbor of the corrugating roll D to move the same nearer to or farther
from the roll C. This arm I carries a spring actuated catch i having a downwar lly
projecting point to engage in recesses formed upon the surface of the hub of the
stock A which surrounds the arbor 4 to hold the arm I as set and maintain the-
rolls CD the desired distance apart. The outer ends of the arm I and catch i are
brought together to release the catch and allow the eccentric arbor 4 to be turned
by the arm I so as to move the corrugating roll D out of engagement with the
corrugating roll C, so that the sheet metal to be corrugated may be introduced.
between said rolls.
This corrugating and cutting tool is exceedingly convenient because combining
in one instrument means for cutting sheet metal and corrugating the same, and it
avoids the necessity of carrying and handling two separate tools.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
First. The combination with the stock, the rigid haudle, the corrugating rolls
and their arbors, of a stationary cutting jaw upon the stock, a moving cutting jaw
and integral arm pivoted to the stock, the moving handle, and a connection from
the end of the arm of the moving cutter to said handle, substantially as and for the
purposes set forth.
Second. The combination with the stock and the handles, of the corrugating rolls.
and means for operating the same, the arbor 3 of one corrugating roll secured in
the stock, the arbor 4 of the other corrugating roll made eccentric and passing
through the stock, and an arm secured to the end of the eccentric arbor 4 and
adapted by its movement to regulate the position of the one corrugating roll to the
other, substantially as set forth.
Third. The combination with the stock and the handles, of the corrugating rolls
and means for operating the same, the arbor 3 of one corrugating roll secured in
the stock, the arbor 4 of the other corrugating roll made eccentric and passing
through the stock, and an arm secured to the end of the eccentric arbor 4 and
adapted by its movement to regulate the position of one corrugating roll to the
other, and a means connected to the arm and acting to maintain the position of the
arm, substantially as set forth.
Fourth. The combination with the stock and the handles, of the corrugating
rolls and means for operating the same, the arbor 3 of one corrugating roll secured
in the stock, the arbor 4 of the other corrugating roll made eccentric and passing
5 through the stock, and an arm secured to the end of the eccentric arbor 4 and
adapted by its movement to regulate the position of the one corrugating roll to the

page_text: other, an enlargement upon the side of the arm, a spring connected to the arm and
acting upon the stock and producing a friction to maintain the position of the arm,
the enlargement when the arm is turned up coming below the arm of the moving
cutting jaw to maintain the handles and jaws in a closed condition, substantially as
set forth.
Fifth. The combination with the stock, the handles, the corrugating rolls,' a
stationary arbor for one corrugating roll secured in the stock and an eccentric
arbor for the other corrugating roll passing through the stock and the hub
projecting therefrom, of a stationary cutting jaw connected to the stock, a moving
cutting jaw and integral arm pivoted to the stock, a link connecting the arm of the
moving cutting jaw to, one handle for operating the cutters, and an arm secured
to the eccentric arbor of one corrugating roll, and a spring connected to said arm
and adapted to frictionally maintain said arm in position, substantially as set
forth.
