IMPROVEMENTS IN STYLES FOR MANIFOLD WRITING AND DRAWING, AND FOR THE PRODUCTION OF STENCIL SHEETS to be as follows
Year: 1884

page_text: I, JOIN DANIEL SPRAGUE of 20 Parliament Street, in the City of Westminster,
Inventor and Patentee, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN STYLES FOR MANIFOLD WRITING AND DRAWING, AND FOR THE
PRODUCTION OF STENCIL SHEETS to be as follows:-
"
This invention has for its object the construction of styles for manifold writing
or drawing in such a manner as to admit of their being used with greater freedom
than those ordinarily employed and without injury to the material to which they
are applied.
The invention consists of a ball or sphere about one sixteenth of an inch in
diameter, more or less, according to the kind of writing or drawing for which it is
to be used, and a holder, cup, or socket made of gun-metal, brass, or other suitable
material through which the ends or part thereof of a horse-shoe or other suitably
shaped magnet, are thrust, so as to make them flush with the interior of the socket,
the holder or socket being attached to a handle similar to an ordinary penholder or
style. Or, the holder may be made of a piece of steel, bent, magnetized, and so
arranged as to embrace a piece of brass or other insulating material. A hollow of
suitable size is then formed in the ends of the combined pieces of metal, and upon
inserting a ball of hardened steel in the hollow it will be found to adhere with
sufficient force to allow of its being handled without fear of the ball falling out,
while at the same time the ball will revolve in any direction with great freedom
when it is drawn over the surface of the paper or other material upon which it is
desired to be used. Styles so made are especially useful when employed for the
purpose of puncturing paper by drawing them over a roughened surface and thereby
producing stencil sheets, or plates froin which copies may be printed.
The holders may if preferred be made with only a single bar magnet passing
through the cup or socket, but in most cases it is better to have those of the form
mentioned in the previous paragraph.

page_text: I, JOHN DANIEL SPRAGUE, of 20 Parliament Street in the City of Westminster,
Inventor and Patentee do hereby declare the nature of my invention for
"IMPROVEMENTS IN STYLES FOR MANIFOLD WRITING AND DRAWING AND FOR THE
PRODUCTION OF STENCIL SHEETS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement reference being had to the accompanying drawings and to the letters and
figures marked thereon, that is to say :-
This invention has for its object the construction of styles for manifold writing
or drawing in such a manner as to admit of their being used with greater freedom
than those ordinarily employed, and without injury to the material to which they
are applied.

-In order that the invention may be more easily understood drawings are attached.
hereto of which the following is a description. Fig 1 is an elevation of the style
and part of the handle, the other part of the handle being in section, of about the
natural size, Fig 2 is a part section and part elevation of a modification of Fig 1,
and Fig 3 is an elevation of a style made with a single bar magnet. Fig 4 is an
elevation, to an enlarged scale, of a style, the handle of which is formed by the
prolongation of the magnet. Fig 5 is a longitudinal sectional elevation of Fig 4,
and Fig 6 is a transverse section through A, B Fig 4. In each of the views similar
letters refer to the same parts.

The invention consists of a ball or sphere about one sixteenth of an inch in
diameter, more or less, according to the kind of writing or drawing for which it is
to be used, and a holder, cup, or socket made of gun-metal; -brass, or other suitable
material through which the ends or part thereof of a horse-shoe or other suitably
shaped magnet are thrust, so as to make them flush with the interior of the socket,
the holder or socket being attached to a handle similar to an ordinary penholder or
style. Or, the holder may bo made of a piece of steel C, C, bent magnetized and
so arranged as to embrace a piece of brass or other insulating material D. A hollow
of suitable size is then formed in the ends of the combined pieces of metal, and
upon inserting a ball E of hardened steel in the hollow it will be found to adhere.
with sufficient force to allow of its being handled without fear of the ball falling
out, while at the same time the ball will revolve in any direction with great
freedom when it is drawn over the surface of the paper, or other material upon
which it is desired to be used.-F is a handle made of wood, or other suitable
material to which the metallic part of the style is attached as shown in Fig 1, or
is inserted in a socket G as in Fig 2, or the handle may be formed by prolonging
the magnet as shown in Figs 4 and 5.-Styles so made are especially useful when
employed for the purpose of puncturing paper by drawing them over the paper
placed on a roughened surface and thereby producing stencil sheets or plates from
which copies may be printed.
A magnetized bar alone may form the holder, or the holders may if preferred be
made with only a single bar magnet passing through the cup or socket, but in most
cases it is better to make them of the form mentioned in the previous paragraph
and shown in Fig 1.

page_text: Having now particularly described and ascertained the nature of my said
invention and the manner in which the same is to be performed, I declare that
what I claim is,
The construction of styles made of magnetized steel with a ball capable of
revolving, and arranged as herein described and shown on the drawings.
