Improvements in Apparatus for Printing from Stencil Sheets.
We, FREDERICK ELLAM and JAMES ELLAM, both of No. 12 King Street, in the
City of London, Manufacturers of Copying apparatus, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to means of printing from sheets which are prepared as
stencils in various known ways, parts of their surfaces being rendered pervious to
ink while the rest remains impervious.
For this purpose we provide two standards at a suitable distance apart staying
them together so as to make a steady framing. In one of these standards, say the
right, we provide a bearing for a spindle which can be turned by a winch or other-
wise, and on this spindle we fit a sleeve which extends nearly the whole length of
the spindle, and has its end fixed in or on the other or left standard which forms
another bearing for the spindle. On the sleeve we mount free to revolve two
flanged wheels stayed together, the one of them at the right being driven by the
spindle and driving the other with it. Between the two wheels we mount on
brackets projecting from the sleeve suitable ductor inking and distributing rollers,
one of these having the upper part of its circumference level with that of the
two flanged wheels, and immediately above this inking roller we mount a pressing
roller. On the flanges of the two wheels we fix the two margins of the stencil
sheet, and between it and the pressing roller we introduce the sheet to be printed;
then, on turning the spindle, and thereby the two wheels, the sheet is drawn
through between the stencil and the pressing roller while the inking roller presses
ink through the pervious parts of the stencil on to the moving sheet.

Improvements in Apparatus for Printing from Stencil Sheets.
We, FREDERICK ELLAM and JAMES ELLAM, both of No. 12 King Street, in the
City of London, Manufacturers of Copying apparatus, 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:-
Our invention relates to means of printing from sheets which are prepared as
stencils in various known ways, parts of their surfaces being rendered pervious to
ink while the rest remains impervious.

page_text: For this purpose we employ apparatus which we shall describe referring to the
accompanying drawings, Fig. 1 is a front elevation and Fig. 2 is a vertical
transverse section. We provide two standards A A at a suitable distance apart
staying them together by stays B so as to make a steady framing.
In one of these standards, say the right A we provide a bearing for a spindle C
which can be turned by a winch D or otherwise, and on this spindle we fit a
sleeve E which extends nearly the whole length of the spindle C and has its end
fixed in or on the other or left standard A' which forms another bearing for the
spindle C.
On the sleeve E we mount free to revolve two flanged wheels F F¹ stayed
together, by stays G G the one of them at the right being driven by the
spindle C and driving the other with it. Between the two wheels we mount on
brackets H H projecting from the sleeve E suitable ductor inking and distributing
rollers K one of these having the upper part of its circumference level with that
of the two flanged wheels, and immediately above this inking roller we mount a
pressing roller P. On the flanges of the two wheels F F we fix the two margins
of the stencil sheet S and between it and the pressing roller P we introduce the
sheet to be printed: then, on turning the spindle, and thereby the two wheels,
the sheet is drawn through between the stencil S and the pressing roller P while
the iuking roller K presses ink through the pervious parts of the stencil on to the
moving sheet.
Ink is contained in a tray T which is from time to time raised by hand to deliver
ink to one of the rollers. Two canis Q acting on the rollers R raise the roller P
to allow the stays G G to pass under it.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we claim
is :-
Apparatus for printing from stencil sheets constructed and operating sub-
stantially as described with reference to the drawings.
