PROVISIONAL SPECIFICATION.
Apparatus for Printing Measurement Marks upon Webs of Fabric.
I, ALEXANDER MELVILLE CLARK, of the Firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of London, Fellow of the Chartered Institute
of Patent Agents, do hereby declare the nature of this invention (a communication
to me by Ferd. Schäfer Söhne Maschinenfabrik, of Pirmasens (Rheinbayern) in
the Empire of Germany,) to be as follows:-
This invention relates to apparatus for printing measurement marks upon webs
of fabric such as paper, cloth, and the like. The number printing mechanism is
mounted within the circumference of the measuring drum, and the invention
consists essentially in the provision of two sets of printing mechanism placed
diametrically opposite each other but coupled together and actuated by the same
parts for printing the one the whole numbers and the other the half measurements
of the standard unit of length.
The invention is illustrated in the accompanying drawings, wherein Figures 1
and 2 are elevations, and Figures 3 and 4 axial and cross sections of the measuring
drum and measurement printing mechanism.
The pressing and measuring drums W1, W2, are mounted in standards St, and
within the measuring drum W2 (whose circumference is equal to one metre, yard,
or other standard unit of length) is mounted the number printing mechanisms N1, N2,
the same being coupled by a diametrical slide rod working in guides f', f2, and
having a slot S embracing the shaft W of the measuring drum. This slide rod is
reciprocated by a bell crank lever H pivoted at a to the end of the drum, and
coupled by one arm to the slide rod whilst the other arm is engaged by a stud and
friction roller in an eccentric cam groove F in a disc E fixed to the standard. As
the measuring drum W2 rotates, the two mechanisms come into operation
alternately, the one N' printing the whole numbers and the other the half
measurements as each comes in turn opposite the pressing roller W¹.
The mechanism N₁ consists of the usual change number wheels and shifting
mechanism, b and c being the two inking devices by which the ink is applied at
each complete revolution of drum W2.

I, ALEXANDER MELVILLE CLARK, of the Firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of London, Fellow of the Chartered Institute
of Patent Agents, do hereby declare the nature of this invention (a communication
to me by Ferd. Schäfer Söhne Maschinenfabrik, of Pirmasens, (Rheinbayern), in
the Empire of Gerinany), 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 apparatus for printing measurement marks upon webs

page_text: of fabric such as paper, cloth, and the like. The number printing mechanism is
mounted within the circumference of the measuring drum, and the invention
consists essentially in the provision of two sets of printing mechanism placed
diametrically opposite each other but coupled together and actuated by the same
parts for printing, the one whole numbers and the other fractions (halves) denoting
in terms of the standard unit of measurement the length of the fabric.
The invention is illustrated in the drawings accompanying the Provisional
Specification, wherein Figures 1 and 2 are elevations, and Figures 3 and 4 axial
and cross sections of the measuring drum and measurement printing mechanism.
The pressing and measuring drums W', W2, are mounted in standards St, and
within the measuring drum W2 (whose circumference is equal to one metre, yard,
or other standard unit of length) is mounted the number printing mechanisms N¹, N',
the same being coupled by a diametrical slide rod working in guides f³, 12, and
having a slot S embracing the shaft W of the measuring drum. This slide rod is
reciprocated by a bell crank lever H pivoted at a to the end of the drum and
coupled by one arm to the slide rod whilst the other arm is engaged by a stud and
friction roller in an eccentric cam groove F in a disc E fixed to the standard.
As the measuring drum W2, rotates, the two mechanisms come into operation
alternately as each comes in turn opposite the pressing roller W¹, the one N',
printing whole numbers and the other N2, the fractional or half numbers denoting
in terms of the standard unit of measurement the length of the fabric.
The mechanism N³, consists of the usual change number wheels and shifting
mechanism, b and c being the two inking devices by which the ink is applied at
each complete revolution of drum W².
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
Apparatus for printing measurement marks upon webs of paper, cloth, and the
like, consisting of two sets of number printing mechanism mounted within a
measuring drum at diametrically opposite points and coupled together by a slide rod
receiving reciprocating motion by the rotation of the measuring drum with regard
to a stationary cam, whereby the printing mechanisms are brought into operation
as each comes alternately opposite the pressing roller, as specified.
Dated this 6th day of January 1896.
