Improvements in Instruments for Forming a Number of Parallel
Lines of Perforations in Stencils or for Ruling a Number of
Parallel Lines of Pencil, Ink, or Colour upon any desired Surface.
I WILLIAM FREDERICK BARTON MASSEY-MAINWARING of 30 Grosvenor Place in
the County of Middlesex, Gentleman do hereby declare the nature of this invention
to be as follows:-
The invention has for its object Firstly to produce a perforating instrument for
forming parallel lines in stencils to lie employed in the reproduction or printing of
music or for other purposes and relates more particularly to that class of stencils which
are formed in waxed paper by means of a small toothed wheel according to an inven-
tion for which Letters Patent were granted to David Gestetner dated June 3rd 1881
No. 2450.
For this purpose I mount a number of fingers independently upon a shaft or axis
carried in a suitable frame in such manner that each finger is capable of revolving
within certain limits, around such shaft or axis.
At the forward end of each of these fingers is mounted upon an axis with capability
of revolving, a toothed, notched or roughened wheel of small diameter.
The rear ends of the fingers are prolonged beyond their shaft or axis and bear upon
a cylinder of rubber in order to enable the toothed wheels to readily adjust themselves
to one uniform plane when in use and also to cause them to bear with an elastic or
spring pressure upon the stencil paper; or other means may be employed to attain
this object.
Any one or more of the fingers may when desired be turned upon the shaft or axis
out of position for use where it or they may be securely held, and the marking
instrument or instruments protected by a metal strap or cover mounted upon centres
carried by the frame, or other means may be employed for this purpose.
The frame instead of being fixed rigidly to the holder as has heretofore been pro-
posed is swivelled thercon; that is to say, it is mounted with capability of revolving
upon a centre carried thereby by which means the toothed wheels are caused more

page_text: certainly to adjust themselves to, and to bear with an equal pressure, upon the surface
being acted upon and to follow the desired course.
According to the second part of my invention, when I desire to rule a number of
parallel lines of pencil, ink or colour upon any desired surface, I, in lieu of the
toothed wheels before described, employ a number of discs or wheels of lead or other
marking material according to an invention for which I have obtained provisional
protection dated July 16th 1885 No. 8629 or I may employ a number of writing or
ruling pens or instruments according to an invention for which I have obtained
provisional protection dated July 16th 1885 No. 8628 for this purpose.
It will be readily understood that useful results may be obtained by mounting other
marking instruments than those hereinbefore described upon the fingers while still
retaining the other features of the invention.
In some cases I may mount marking instruments upon. both ends of the fingers.
Improvements in Instruments for Forming a Number of Parallel
Lines of Perforations in Stencils or for Ruling a Number of
Parallel Lines of Pencil, Ink, or Colour upon any desired Surface.
I, WILLIAM FREDERICK BARTON MASSEY-MAINWARING of 30 Grosvenor Place in
the county of Middlesex, Gentleman do hereby declare the nature of my said
Invention and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement, that is to say :-
This invention has for its object, Firstly, to produce a perforating instrument for
forming parallel lines in stencils to he employed in the reproduction or printing of
music or for other purposes and relates more particularly to that class of stencils
which are formed in waxed paper by means of a small toothed wheel according to an
invention for which Letters Patent were granted to David Gestetner dated June 3rd
1881, No. 2450.
For this purpose I mount a number of fingers independently upon a shaft or axis
carried in a suitable frame in such manner that each finger is capable of revolving
within certain limits around such shaft or axis.

page_text: they may be securely held and the marking instrument or instruments thereof pro-
tected by a metal or other strap or cover e mounted upon centres a³ carried by the
frame a; or other means may be employed for this purpose. In the modification
represented at Figure 1 the fingers c are shown provided with a perforating wheel d
mounted at each end thereof.
According to the second part of my invention when I desire to rule a number of
parallel lines of pencil in lieu of the toothed wheels d. hereinbefore described I employ
à number of discs or wheels of lead or other marking material mounted on the axis c
according to Patent No. 8629 of the year 1885 herein before referred to or when I
desire to rule a number of parallel lines in ink or colour, I employ the arrangement
represented at Figures 5 and 6 in which the fingers c are made hollow to contain ink
or other marking fluid, the forward ends of said fingers being provided with a grooved
wheel for conducting the ink or other marking Huid to the paper or other surface
in the manner described in the specification of Patent No. 8628 of the year 1885
hereinbefore referred to. The rear ends of the hollow fingers c are provided with
suitable plugs or stoppers.
It will be readily understood that useful results may be obtained by mounting other
marking instruments than those hereinbefore described upon the fingers c while still
retaining the other portions of the invention.
In some cases I employ an inking roller, see dotted lines in Figure 1 to supply
ink to the dises or wheels d which latter may be formed with plain or toothed peri-
pheries according as it is required to produce plain or dotted lines. The inking roller
is preferably carried by arms mounted upon the frame a in such manner as to
permit the said inking roller to be placed in position for supplying ink to the
marking instruments or to be removed from contact therewith when required. The
inking roller may be formed of absorbent material which will from time to time be
saturated with ink or other marking fluid or material; or a pad may be used in lieu of
such inking roller, or the said roller f may be used in combination with a suitable
fount or supply apparatus as is well known in the printing trade.
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 :-
1. The peculiar construction of instruments for ruling parallel lines of perforations
substantially as herein shown and described with respect to Figures 1 to 4.
2. The peculiar construction of instrument for ruling a number of parallel lines
of pencil, ink or colour substantially as herein shown and described with respect to
Figures 5 and 6.
3. The combination of swivelled frame a, holder b, fingers e mounted on axis a¹,
rubber cylinder a² and strap or cover e, the said fingers c, being fitted at one or both
ends with a perforating or marking instrument all substantially as herein shown and
described and for the purpose stated.
