PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Measuring and Marking Continuous
Lengths of Cloth, Paper, or similar Material.
1, WILLIAM GEORGE GASS, Engineer, Atlas Foundry, Nelson Street, Great
Lever, near Bolton, in the County of Lancaster, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an appliance or appliances to be used in connection with
that class of machine in which the cloth, web of paper, or similar material or fabric
is measured by passing it over a drum or roller of definite circumference the length
being registered by a dial or similar contrivance. The marking may be required
either every five yards or metres or similar intervals with no marks for the separate
yards, metres, or portions thereof or it may be required every yard or metre or
similar length with separate marks for the divisions of said yards or metres.
The apparatus consists of a shaft or the equivalent therefor-hereinafter referred
to as the "shaft" which is placed parallel with the measuring drum or roller
hereinafter referred to as the "drum."
The shaft" receives a rotary motion from the "drum" through a chain of
wheels or the equivalent thereof so that it revolves at the requisite speed-and in
case the "drum" should not be of absolute circumference compensating gear is
introduced into chain of wheels before referred to so as to make it exactly correct.
On the shaft" is carried a stud hereinafter referred to as the 'stud -the axis
of which is at right angles to "shaft" and which is capable of being moved along
and fixed at any point on shaft between bearings of said "shaft." On this
'stud is carried a disc or wheel hereinafter referred to as the "disc" which is
capable of free rotation in one direction on the "stud" as a centre.
This "disc" is provided at its periphery with a series of pins-hereinafter
referred to as the "pin "equidistant from each other each kept in place with a
spring and cach pin capable of being independently projected beyond the periphery
of said disc when required to mark. On the end of each pin and forming part
of it is a figure or mark-which may be a numeral or any desired figure and which
may be of any suitable material such as metal, wood, rubber or similar substance.
Attached to the boss of the 'disc is a ratchet wheel having the same number of
teeth as there are pins in the periphery of "disc" a loose arm hereinafter referred
to as the "arm," pivotted on boss of said 'disc' carries a ratchet pawl which
engages with teeth of ratchet before mentioned when motion is given to "arm.'
Forming part of said "arm is an extension piece provided with adjustable setting
up screw which through a small bell crank lever causes the desired 'pin' in said
disc to be projected beyond periphery and come in contact with fabric at desired
point this movement takes place when 'disc' is in its correct position and imme-
diately after the mark is made the figure recedes and revolves clear of the fabric
and the ink roller hereinafter referred to.
"
"
The requisite motion is given to "arm" either by a rod having a reciprocating
movement a square supplementary shaft parallel with "shaft" having an inter-
mittent oscillating movement or a continuous rotary one-such requisite motion
being obtained either from a cam or similar device placed on one of the chain of
wheels herein referred to as connecting the "drum" and "shaft or from the
periphery of one of these wheels.
'
23
Attached to 'stud' is an extension piece which forms a detent into which
each successive pin is pressed so as to hold disc in place during its period of rest.
In cases where it is required to mark the numerals consecutively it is proposed to
use two discs similar in construction to the one herein referred to and connected

page_text: together by intermittent gearing so as to have a correct relative movement-and
motion to be transmitted to them in a similar manner as in the case of the single
'dise' namely by a reciprocating rod or an oscillating or revolving supplementary
shaft and suitable mechanism-also where supplementary marks at the divisions of
yard or metre are required it is proposed to employ a supplementary arm carried
"shaft" and provided where needed with suitable marks.
on
Means are provided for supplying the figures with coloring material at the
proper time by an ink roller or its equivalent. By means of a clutch or similar
device the marking arrangement can be thrown out of gear and the measuring drum
or marking mechanism can revolve independently.
Though I have herein described the general nature of the invention the foregoing
must not be taken as being absolutely binding in all its details as various minor
alterions will be required to suit it to the various type of measuring machine at
present in use and to which it may be adapted but which will not alter the main
features of the invention.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Measuring and Marking Continuous
Lengths of Cloth, Paper, or similar Material.
1, WILLIAM GEORGE GASS, Atlas Foundry, Nelson Street, Great Lever, near
Bolton, in the County of Lancaster, Engineer, 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 :-
My invention consists of an apparatus by means of which numerals, figures, or
any desired mark, or impression may be made at definite intervals as desired on the
surface of a moving web or continuous length of cloth, paper, or similar material,
which is being passed over a drum or its equivalent of definite circumference for the
purpose of ascertaining the length of the material.
In order that my invention may be more readily understood, I will at once
proceed to a detailed description by reference to the two sheets of drawings which
accompany this Application: it being understood that the same letters apply to
similar parts throughout the several views.
In Sheet 1. Figs. 1 to 4 are details of views of parts of the mechanism by which I
accomplish my object, and in Sheet 2 Figs. 5 and 6 shew the apparatus complete.
Fig. 5 being an elevation and Fig. 6 an end view shewing also the position of the
measuring drum, and the manner in which the cloth or fabric is passed over the
said measuring drum. Fig. 7 being a detail of the frame which forms the shaft for
carrying the marking wheel.
Figs. 1 and 2 are plan and section respectively of the marking wheel-this
consists of a light metal disc A. A. provided with concentric rims a a'; in the
rims a al are placed a number of pins (in this case 20) each provided at its outer
end with suitable marks or figures; each pin has also a small key which
prevents the said pin from making any rotation on its own axis, while it is free to
be pushed outwards, the return being secured by means of the coiled spring c
which encircles it, and which acts through the cross pin c¹ fixed in B. The marking
wheel A A is carried by and is free to revolve on stud D, provided at each end with
a thread and wing nuts d d¹.
Fastened on the boss of wheel A A is a ratchet wheel E E having as many
teeth as there are pins in the periphery of A. A and of a corresponding relative
pitch an arm F moves on the boss of wheel A A as a centre, and through ratchet
pawl gives motion to ratchet wheel E E and through that to wheel A A.
Fastened on stud D is a plate G a portion of which has a projection at g to form a
detent, so that each pin B will in turn form a catch to prevent wheel A A returning

page_text: after having been moved by catch 1. An extension of G carries an ink roller g
which runs loose on a stud.
Attached to plate G and loose on a stud is a bell crank lever H; when
arm F is moved the set screw h which it carries comes in contact with one end of
the bell crank lever H and as this movement is continued the other arm of H comes
in contact with end of pin B and presses it forward.
A coiled spring Fig. 1 f ensures return of arm F and the pin B returns through
the action of its own spring. Fig. 7. Sheet 2 is a rectangular frame II one side of
which is removable and provided at each end with trunnions which run in
suitable bearings carried from machine to which this mechanism is attached:
through the centre of i, a hole is drilled through which passes a pin J. In each
long side of this rectangular frame and extending the whole length of it, is a
parallel slot in which stud D is fitted, and in which it is free to be moved as
required. Attached to one side of each end of frame II are bearings kk¹ carrying
a square rocking shaft K which receives its motion through the lever L and finger
(Figs. 3 and 4) from this shaft motion is given to arm F through the lever M and
small link m (Figs. 1 and 2).
A frame (Figs. 5 and 6) carries the chain of wheels n, n N n which transmits
the motion froin the measuring drum A to shaft i of frame 11.
n.receives its motion from shaft of drum A and is provided with a suitable clutch
so that it can be thrown out of gear when desired.
n is an intermediate dead wheel. N is also an intermediate wheel, the size of
which depends on the number of impressions required, relatively with the revolutions
of A. On the side of N is a cain surface N' which consists of three movements
via, a risc, a rest, and a return. A lever P carried on a stud projects from O and
receives its motion from the cam surface N' acting on the small friction roller pl.
The chain of wheels are so arranged that the frame II and all the parts attached
to it revolve at the same speed as the measuring drum A.
The action is as follows-the clutch on wheel n is thrown out of gear and the
cloth or fabric threaded up through the machine and drawn tight over the
measuring drum-the wheel A A is revolved by hand on its axis and the frame I I
is turned also by hand until the zero figure points against the cloth.
The clutch on n is then thrown into gear and the machine started-as the drum A
revolves the wheel A A is carried round by the frame I I driven through the chain
of wheels n, n', N, n2, until the cam surface N¹ comes in contact with roller
P of
lever and presses it back, this forces the pin J towards level L and causes it to
press the finger lover, giving movement to shaft K. The lever M through link m
pulls arm F and causes wheel A A to make a movement equal to the pitch of one
pin B, thus bringing the next consecutive one to its place nearest the cloth as it is
passing over the drum A.
At the same time the lever H presses the pin which has just been brought
forward, outward, and causes it to make an impression on the cloth, the figure
having previously received a supply of marking fluid as it passed the roller g'.
As the rotation of wheel N continues the cam surface N' releases lever P and
through the action of spring the arm F is pulled back and through the link m,
arm M finger and lever L the pin J is pushed back and everything is ready for
the next movement which is an exact repetition of the one before it with 20 figures
in wheel A impressions are made every 5 yards or metres up to 100, and then
recommences at 5.
It will be noticed on reference to Fig. 6 that the axis of rotation of wheel AA
is at right angles to the axis of rotation of frame 1 I, this is done in order that the
rotation of A. A may take place while A A is clear of the drum A.
The wheel A is so set that when revolving normally the face of the figures are
about inch clear of the cloth on drum A, and only come in contact with the cloth
at the moment the figure is pressed outwards by lever H.
I have herein described my invention as accurately as possible, but it must be
understood that in attaching it to machines of existing and different types,

page_text: alteration may be needed in the minor details, but it will not alter the general
principle of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a marking device, the combination of a marking wheel A A, a rectangular
frame carried on trunnions, the hollow trunnion the rocking shaft K, the
arm, lever Land pin J all substantially as and for the purpose specified.
2. In a marking device, the combination of the rectangular frame II, the pin J
the lever P, chain of wheels n, n' N, n², the cam surface N on wheel N substantially

3. In a marking device, the combination of the wheel A A, the loose pins B B,
the ratchet wheel E E, the arm F, the pawlf, the spring the screw h, the
detent the bell crank lever H all substantially as and for the purpose specified.
4. In a marking device, the combination of the wheel A A, the stud D, carried
in the manner described, the frame G the ink roller g. all substantially as and for
the purpose specified.
5. In a marking device, a wheel AA with axis of rotation at right angles to
axis of frame or shaft II, which carries it, provided with loose pins B B to carry
the figures or stamps, each provided with a key b, a coiled spring c and pin c' and
which makes an impression only when the figure is pressed beyond the normal
circumference all substantially as and for the purpose specified.
