Year: 1884

page_text: I NETTIE HANBURY 272 Regent Circus London W. Eng. do hereby declare
the nature of my invention for AN IMPROVED TRACING WHEEL FOR MARKING
PATTERNS to be as follows:-
An instrument for the purpose of impressing upon or perforating material or
paper,
It is mado of steel & wood & is about six inches in length, the steel portion
being formed into two small wheels, the points of which are sharp & which are
used for marking or perforating the fabric, the wood part forming the handle.
The Double Tracing Wheel marks two lines at one time, one line to cut by & the
other line to sew by leaving a space of five eighths of an inch between the two
lines.

page_text: I, NETTIE HANBURY, of 272 Regent Circus, in the County of Middlesex, wife of
John Hanbury, do hereby declare the nature of my invention for "AN IMPROVED
TRACING WHEEL FOR MARKING PATTERNS, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to an improved tracing wheel for making patterns.
In the accompanying sheet of illustrativo drawings Fig 1 is a side view of a
tracing wheel according to my invention and Fig 2 is a plan or top view of
the same.
a is the handle of the instrument, conveniently formed of wood and provided at
its forward end with a stock piece of metal such as brass, to which the tracing
discs or wheels c. c are pivotted at d. d in any convenient manner as for instance
by set screws, or by a pin rivetted over at its ends. The tracing discs or wheels c. c
may be made of hardened steel and cach is formed with a series of sharp pointed
teeth c* c* at its periphery.
The discs or wheels are arranged to rotate in parallel planes.
The instrument is used as follows:-
The pattern or device to be copied is placed over the material to which the
pattern or device is to be imparted, one of the discs or wheels is then passed over
the outline of the pattern or device with a moderate degree of downward pressure
whereby a copy of the said pattern or device will be transferred or imparted to
the material beneath in the form of a series of indentations. or perforations. Where
lines in the pattern to be copied are parallel and at a distance apart corresponding
with that of the wheels c. c, then the two discs or wheels are used simultaneously,
one disc or wheel being passed over each such line on the pattern or device and the
same being transferred as before. Sometimes it is required to produce on the
material used a line or lines parallel with those obtained from the pattern or
device as a guide whereby to cut out the material. Such a line or lines may be
formed as before described by placing both discs or wheels over the pattern or
device and using one of them to trace out the pattern whilst the other traces out
an additional parallel line.
The discs or wheels may be made adjustable as respects their distance apart.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is-
The construction and use of the improved tracing wheel or apparatus for
marking patterns substantially as herein before described with reference to the
drawings.
