Scheib, all of New York City, in the State of New York, in the
United States of America, for the Invention of "AN IMPROVED
MACHINE FOR MAKING CUT NAILS
"
COMPLETE SPECIFICATION filed by the said Henry Scheuerle, Daniel
Gugisperg, and Carl Scheib at the Office of the Commissioners of
Patents, with their Petition and Declaration, on the 2nd June
1870, pursuant to the 9th Section of the Patent Law Amendment.
Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
SCHEUERLE, DANIEL GUGISPERG, and CARL SCHEIB, all of New York
City, in the State of New York, in the United States of America, send
greeting.
WHEREAS we are in possession of an Invention for "AN IMPROVED
MACHINE FOR MAKING CUT NAILS," and have petitioned Her Majesty to
grant unto us, our executors, administrators, and assigns, Her Royal

page_text: Letters Patent for the same, and have made solemn Declaration that we
are the first and true Inventors thereof.
NOW KNOW YE, that we, the said Henry Scheuerle, Daniel Gugisperg,
and Carl Scheib, do hereby declare that the following Complete
Specification, under our hands and seals, fully describes and ascertains
the nature of the said Invention, and in what manner the same is to be
performed, in and by the following statement:-
The nature of our Invention consists in the arrangement of a fixed
frame between which the pincers for holding the nail plate from which
the nails are to be cut is arranged, said pincers being combined and
connected with suitable mechanism to impart to the forward end of the
nail plate the desired motion to produce the required wedge shape of
the brad or cut nail, dispensing thereby with the vibrating of the frame.
Our Invention consists, further, in the arrangement of suitable springs
or levers at the forward end of the fixed frame, between which said
springs or levers the forward end of the nail plate is held fast and
guided, and which are operated by suitable levers in such a manner as
to move this end of the nail plate alternately from one side of the
machine to the other side, for the purpose of bringing either the one or
the other end of the nail blank in the required position to be acted
upon by the heading die after the wedge-shaped strip or blank of metal
has been sheared off.
And further our Invention consists in the arrangement of suitable
springs at the connection of the levers, through which the forward end
of the nail plate is operated, whereby two or three different sizes or
lengths of nails can be cut in one and the same machine without
making any alteration on said machine for that purpose.
In order that our Invention may be fully understood we shall now
proceed more particularly to describe the same, and for that purpose we
shall refer to the several Figures on the Sheet of Drawings hereunto
annexed, forming a part of this Specification, and to the letters of
reference marked thereon.
Figure I. represents a plan of a nail machine embodying our
Invention; Figure II. is a side elevation of part of the machine with
the outside of the frame removed; Figure III. shews a cross section of
the nail plate frame, shewing part of the gearing; Figure IV. shews the
levers and the manner of their connection, which operate the forward

page_text: end of the nail plate. Similar letters represent similar parts in all the
Figures.
In the accompanying Drawing A represents the main frame support-
ing the main shaft B for carrying the cams to operate the cutter
head C and the guide bar O, and to give the required motion to the
cutter head E and the heading die blocks F, F¹, all of which are
arranged and constructed in the usual manner. Upon the main shaft B
a pinion G is placed meshing into a wheel H fast on a shaft J connected
through the bevel gearing K with a shaft L to communicate the
desired motion to said shaft L. To the end of the main frame A
bearings D, D', are attached, in which the projecting arms of the
frame M are supported and fastened. These bearings D, D', are so
constructed that the frame M, where supported by said bearings, may
be readily raised or lowered and moved towards the one or the other side
of the machine, as may be required, and at the same time facilitate the
removal of said frame M to give easy access to the cutters and, dies
when required. The forward end of the frame M. rests upon the
frame A, and the after end is supported by the rod S (see Figure II.)
The inner sides of the central part of the frame M are made paralell and
act as guides for a block N fitted into the same and capable of sliding
freely forwards and backwards. Into this block Ņ a second block P is
fitted, as well as a bar Q, capable of sliding or moving sideways or at a
right angle to the frame M. R is a rod provided with pincers R' at its
forward end, which hold the nail plate T. The after end of this pincer
rod R is attached to the block P, moving sideways in the block N, and
is provided with a projecting pin a entering the sliding bar Q, for the
purpose of receiving the desired motion from said bar. The forward end
of the nail plate T is guided by the ends of the spring levers n, n',
attached to the inner sides of the frame M and operated by suitable
levers in the manner and for the purpose herein-after explained. On
the side of the frame M brackets are attached, upon which the crank
levers V, V, are centered. The outer ends of these cranks are con-
nected together by a rod W, to which latter the sliding bar Q is.
attached by means of a ball joint d. Near the lever V the bar or
rod W is connected through the rod e with a crank X attached to the
end of the shaft L operated from the main shaft B as above described.
The crank lever V is extended below its centre of motion, forming a
lever V (see Figure 2), which is connected with a bar to passing under
the frame M and to which the ends of the levers m, m³, are attached in

page_text: the manner hereafter described. These levers m, m², turn on centers 8, 8¹,
fast on the frame M. and act at their other ends against sliding pins v, v1,
passing through the sides of the frame M, and which said pins v, v¹,
operate the levers or spring levers, n³, attached to the inner sides of
the frame M in such a manner as to guide the nail plate T held fast
between them and to move the same either towards the one or the
other side to the heading dies F, F', as may be required. The levers
m, m³, are attached to the bar wo by being fastened into suitable
blocks 3, 3¹, capable of moving in slots in said bar w, and which said
blocks are acted upon and kept in their right positions by springs x, x¹,
situated in the slots in the bar w (see Figure I. and Figure IV.). By this
arrangement of keeping the blocks 3, 3¹, and consequently the ends of
the levers m, m³, in their proper position through the action of strong
springs, said position will readily accomodate itself to two or three
different sizes or width of the nail plate and will consequently enable
two or three sizes or lengths of nails to be cut in one and the same
machine without any alteration being made in the same.
The operation of the machine is as follows:-The revolving crank X
will communicate a vibrating motion to the bar or rod W, and con-
sequently a corresponding motion to the sliding bar Q through its
connecting rod d. The forward end of the nail plate T being held
between the ends of the spring levers n, n', while the after end of the
pincer rod R is connected through its end pin a with the sliding bar Q,
will receive a vibrating motion towards the one or the other side,
producing a corresponding motion on the forward end of the nail plate T,
in such a manner as to move the same obliquely to the face of the cutter
head E before the same cuts off the nail blank, so as to give thereby the
required wedge shape to the brad or cut nail. At the same time the
lever V has moved the bar w, in such a manner that the lever m has
acted against the sliding pin v (see Figure I.), forcing thereby the spring
lever n inwards, thereby moving the end of the nail plate T towards the
left-hand side of the machine, so that when the cutter E has sheared off
a wedge-shaped strip of metal, the same will be in a position for the
heading die F to operate upon the same and complete the brad or nail.
The after end of the pincer rod R is then moved to the other side of the
frame, and at the same time the lever m¹ made to act through the pin v¹
against the spring lever n³, so as to move the forward end of the nail
plate T towards the right-hand side of the machine, reversing thereby
the oblique position of said nail plate T, and bringing the next strip of

page_text: metal sheared off by the cutter E in a position to be acted upon by the
heading die F. To the lower part of the block N a band or chain Y is
attached, having its other end fastened to the end of the frame M passing
over suitable rollers h, h, and loaded by a weight Z; through which
arrangement the block N and consequently the nail plate T is moved
towards the cutter, bringing the latter under the cutting shears E after
cach operation. After each operation the nail plate T will be diminished
in length, and consequently the distance between the ends of the
levers n, n, (which act as a fulcrum for said nail plate and pincer rod),
and the sliding bar Q will gradually diminish in the same proportion, in
consequence of which the amount of motion communicated to the after
end of the pincer rod R or to the sliding bar Q, must be diminished in
the same proportion, so as to present the nail plate T always in the same
oblique position to the cutter E, to obtain a uniform taper to each
and every brad or nail. To obtain this object the crank V and the
crank V are made of different length, whereby the amount of motion
of the bar W is greatest near the crank V¹, and consequently the motion
communicated to the sliding bar Q and to the end of the pincer rod R
when near said crank V and gradually diminishes, in the desired ratio,
as the block N together with its sliding bar Q moves towards the
crank V after each operation. The amount of this motion and con-
sequently the taper of the brad or nail can easily be regulated by the
different lengths of the cranks V and V¹.
Having now described and particularly ascertained the nature of our
said Invention, and the manner in which the same is or may be used,
we would observe in conclusion that what we consider to be novel and
original, and therefore claim as our Invention is,--
First. The arrangement of the pincer rod R, to which the nail plate T
is attached, in combination with the sliding bar Q fitted into a moveable
block N, and through which motion will be given to the after end
of said pincer bar R, substantially as and for the purpose set forth.
Secondly. We claim communicating to the after end of the pincer
bar R a vibrating motion diminishing gradually as the same advances
towards the machine, substantially as and for the purpose herein-before
described.
Thirdly. We claim the arrangement of two cranks V, V₁, of unequal
length, connected by a bar or rod W, and operated from a rotating shaft L
in combination with a sliding bar Q, substantially as specified.

page_text: Fourthly. We claim the arrangement of the sliding block N, operated
by a weight Z in combination with the block P and sliding bar Q
arranged to receive the end of the pincer rod R, substantially as set
forth.
Fifthly. We claim the arrangement of the levers or spring levers n, n
on the inside of the frame M, guiding the nail plate T, and acting as a
fulcrum on and through which the nail plate will be moved, substantially
as and for the purpose herein-before set forth.
Sixthly. We claim the combination of the levers or springs n, n³,.
sliding pins v, v¹, levers m, m³, springs x, x¹, bar w, and crank V",
operating together in the manner and for the purpose substantially as.
set forth and described.
In witness whereof, we, the said Henry Scheuerle, Daniel Gugisperg,
and Carl Scheib, have hereunto set our hands and seals, this
Eighteenth day of May One thousand eight hundred and seventy.
