"
15, Water Street, Liverpool, in the County of Lancaster, Consulting Engineer,
for an Invention of IMPROVEMENTS IN NIPPERS." A communication from
abroad by Thomas G. Hall, of Brooklyn, County of Kings, State of New
York, United States of America.
PROVISIONAL SPECIFICATION left by the said Frederick John Cheesbrough
at the Office of the Commissioners of Patents on the 20th November 1881.
FREDERICK JOHN CHEESBROUGH, of the Office for Patents, 15, Water Street,
Liverpool, in the County of Lancaster, Consulting Engineer. " IMPROVEMENTS IN
NIPPERS." A communication from abroad by Thomas G. Hall, of Brooklyn, County
of Kings, State of New York, United States of America.
This Invention consists of certain improvements upon a nipper, for which British
Letters Patent were granted to Alexander Melville Clark, as a communication
from Thomas Greenman Hall, which Letters Patent bear date 24th September 1878,
No. 3772.
The improvements making the subject matter of this present Invention
consist,-
First. Of a recess and lip cut in each jaw of the nippers to receive and hold in
position the reacting spring.
Second. Of a cog, pin, or roller connection between the handles of the nippers
opposite their fulcrums by which they are made to act together. In all other
respects the nippers are the same as that for which British Letters Patent as
aforesaid, No. 3772, dated 24th September 1878, were granted.
The object of the recess before referred to is to form an angular receptacle to
hold the reacting spring. For this purpose the recess is made deepest at its top end,
so that when the two jaws are put together they form a wedge shaped receptacle
into which the head of the spring is fitted and held.
The lips at the head of the recess prevents the spring from slipping up towards

page_text: the cutting edges of the nippers, and the wedge form of the recess prevents it from
slipping down towards the levers.
The object of the cog or roller connection between the levers is to make the
handles act exactly alike, so that one jaw shall not travel faster or with more force
than the other.
There is a loose roller set into two correspondingly shaped cavities cut in the
handles opposite the fulcrums, both handles being made exactly alike, so that one
set of milling tools only are necessary to make both handles. Instead of the loose
roller a cog tooth may be raised on one handle, and works in a recess cut in the
other handle, making a male and female handle; this necessitates two sets of
milling tools to fit them together. In all other respects the two devices accomplish
precisely the same object.

by the said Frederick John Cheesbrough in the Great Seal Patent Office on
the 26th May 1882.
FREDERICK JOHN CHEESBROUGH, of the Office for Patents, 15, Water Street,
Liverpool, in the County of Lancaster, Consulting Engineer. "IMPROVEMENTS IN
NIPPERS." A communication from abroad by Thomas G. Hall, of Brooklyn,
County of Kings, State of New York, United States of America.
This Invention relates to certain new and useful improvements in nippers, of
which the following is a description in such full, clear, concise, and exact terms as
to.enable any one skilled in the art to which said Invention appertains, or with
which it is most nearly connected, to make and use the same, reference being had
to the accompanying Drawing making part of this Specification, and to the figures
and letters of reference marked thereon.
This Invention consists of certain improvements upon a nipper, for which British
Letters Patent were heretofore granted to Alexander Melvil Clark, as a communi-
cation from Thomas G. Hall, of Brooklyn, in the County of Kings, State of New
York, United States of America, and which Letters Patent are dated September
24th, 1878, and are numbered 3772 of that year.
Figure 1 of the Drawing is a plan of the nipper showing all its operative parts.
Figure 2 is an edge wise view of the completed nipper; and
Figure 3 is a modification of Figure 1.
a, b, are the cutting jaws, of which e, f, are the fulcrums and c, d, the levers.
g is the reacting spring, and p the side plates by which the operative parts are
held. i, k, are the long ends of the lever handles, and n, o, the short ends; q is a
gauge screw to keep the jaws from slamming together.
The improvements making the subject matter of this Invention consist,-
First. Of a recess and lip cut in each jaw of the nippers to receive and hold in
position the reacting spring.
Second. Of a cog, pin, or roller connection between the handles of the nippers
opposite their fulcrums, by which they are made to act together. In all other
respects the nippers illustrated by the accompanying Drawing is the same for
that for which said Patent was granted, No. 3772, A.D. 1878.
The recess above referred to is shown in the Drawing by x, x, and the lip at the
head of each recess is shown by v, v.
The object of the recess is to form an angular receptacle to hold the reacting
spring. For this purpose the recess is made deepest at its top end, so that when
the two jaws are put together they form a wedge shaped receptacle into which the
head of the spring is fitted and held.
The lips at the head of the recess prevents the spring from slipping up towards
the cutting edges of the nippers, and the wedge form of the recess prevents it from
slipping down towards the levers.
The cog or roller connection between the levers is shown by o', Figures 1 and 3,
and the object of this connection is to make the handles act exactly alike, so that one
jaw shall not travel faster or with more force than the other. In Figure 1 of the
Drawing the pin o' is a loose loose roller set into two correspondingly shaped cavitie
cut in the handles opposite the fulcrums l, m, both handles being made exactly
alike. In this case only one set of milling tools are necessary to make both
handles, but in Figure 3 the cog tooth o¹ is raised on one handle and works in a
recess cut in the other, making a male and female handle that necessitates two sets

page_text: of milling tools to fit them together. In other respects the two discs accomplish
precisely the same object.
What is claimed as improvements upon the nippers patented aforesaid is,-
First. A receptacle (x, x,) and lip (v, v,) in combination to receive and hold the
spring.
Second. The cog or roller connection between the handle fulcrums l, m,
substantially as described for the purpose specified.
In witness whereof, I, the said Frederick John Cheesbrough, have hereunto
set my hand and seal, this Twenty sixth day of May, in the year of our
Lord One thousand eight hundred and eighty two.
FREDERICK JOHN CHEESBROUGH. (L.S.)
