An Improved Perforating, Measuring, Dating or Stamping, and
Recording Apparatus.
I, THOMAS BINNIE RALSTON of 234 Buchanan Street, Glasgow in the County
of Lanark, Iron Merchant, do hereby declare the nature of this invention to be as
follows:
arc
This invention relates to apparatus for perforating ribbons or strips of paper or
the like at measured intervals for dating or stamping the length between each row
of perforations and for recording the number of lengths delivered from the
instrument and the improved apparatus consists of a box or case containing the
coil of ribbon to be dealt with. In the box or case there is carried on a spindle a
drum which may be of square triangular or other angular cross section or of
cylindrical form and along the edges of the said drum perforating combs are
secured the teeth of which project beyond the edges. At one end the drum has a
ratchet wheel upon it which is acted upon to turn the drum through an
corresponding to one of its facets by a pawl carried by a frame secured on the
spindle on which the drum is loosely centred the said pawl being actuated by a
lever or crank secured upon the spindle at the outside of the box or case and which
has a movement through a quarter of a circle. The frame has a spring connected
to it by which after each forward impulse the pawl is assisted in being drawn back
behind the next tooth of the ratchet wheel and to prevent the drum from at the
same time also moving backwards a second pawl centred within the casing and
having a spring in conjunction with it is geared with the ratchet wheel.
The frame on the spindle of the drum carries an inking roller and above the
said roller there is fitted inside the box or case a spring plate or platen having
removable type corresponding to the matter desired to be impressed upon the
ribbon or strip secured in it the said type being removable if desired. The platen
or plate is hinged to the box or case at its rearward end and it is pressed downwards
upon the ribbon or strip by springs attached to the lid of the box or case. On each
partial rotation of the drum by the action of the lever or crank that is to say after
one impression has been made upon the strip or ribbon the spring plate or platen is
lifted up from the ribbon by heels made on the end of the frame acting upon it the
face of the type being at the same time re-supplied with ink for the next impression
by the inking roller passing under it. The paper is kept stented as between the
roll on which it is wound and the drum by a roller or pad carried by a spring
secured to the rearward end of the box and which end is hinged so as to open or
fold downwards when required the whole case being locked close up by securing
the lid and the said folding end together. The frame carrying the inking pad and
pawl has a supplementary frame hinged or jointed to it the forward end of which
folds over the combs at the edges of the drum and holds the strip or ribbon tightly
in position having for that purpose a heel which in moving the drum forwards
bears on the underside of a spring and delivers the desired length of strip over an
inclined plate. The said heel in moving the apparatus back to its normal position
over rides the spring in which position the supplementary frame does not bear upon
the strip. To render the apparatus self recording the perforating drum is geared
with one or more dials by any suitable mechanism.

An Improved Perforating, Measuring, Dating or Stamping, and
Recording Apparatus.
1, THOMAS BINNIE RALSTON of 234 Buchanan Street, Glasgow in the County
of Lanark, Iron Merchant, 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 :—
This invention relates to apparatus for perforating ribbons or strips of paper or
the like at measured intervals, for dating or stamping the length between each row
of perforations and for recording the number of lengths delivered from the
instrument.
The improved apparatus is illustrated on the accompanying drawings, Fig. 1
being a vertical section on the line-c
- Fig. 2, which figure is a plan with the lid
of the casing thrown back and with a portion of the apparatus removed for greater
clearness, and it consists of a box or case A. containing the coil B of ribbon to be
dealt with. In the box or case there is carried loosely on a spindle a drum C
which may be of square, triangular or other angular cross-section or of
cylindrical form and along the edges of the said drum or around its circum-
ference perforating combs are secured. At one end the drum has a ratchet
wheel c secured to it which is acted upon to turn the drum through an arc by
a pawl a carried by a frame D secured on the spindle a on which the drum is
loosely centred the said frame being actuated by a hand lever or crank E secured
upon the spindle at the outside of the box or case A. The frame D has a spring F
connected to it by which after each forward impulse the pawl a is assisted in being
drawn back behind the next tooth of the ratchet wheel c and to prevent the drum
from at the same time also moving backwards a second pawl e centred within the
casing and having a spring in conjunction with it is geared with the ratchet
wheel c.
The frame D on the spindle a carries an inking roller G and above the said
roller is fitted inside the box or case A. a plate or platen H having removable type y
secured in it corresponding to the matter to be impressed upon the ribbon or
strip B. The platen or plate H is hinged to the box or case at its rearward end g
and it is pressed downwards upon the ribbon or strip B by springs attached to
the lid h. On each partial rotation of the drum C by the action of the hand lever
or crank E that is to say after one impression has been made upon the strip or
ribbon the spring plate or platen H is lifted up from the ribbon by heels or rollers i
carried in the end of the frame D acting upon it the face of the type being at the
same time resupplied with ink for the next impression by the inking roller G
passing under it. The paper B is kept stented as between the roll on which it is
wound and the drum C by a roller or pad I carried by a spring J secured to the
rearward end of the box and which end is hinged so as to open or fold downwards
when required the whole case being locked close up by securing the lid and the
said folding end together. The rotation of the roller or drun on which the paper
is wound is braked by a spring w one end of which is secured to the side of the
box or case A its other extremity acting against one end of the roller. The
frame D carrying the inking roller G and pawl a has a supplementary frame K
hinged or jointed to it at j. This frame which embraces the ends and one face of
the drum C folds over the combs b against which it is pressed by a heel on the
platen H. The heel is shewn on Fig. 4 and its function is to hold the strip or
ribbon tightly in position.
The frame K has a heel k which when the drum is turned forward to deliver a
section of the ribbon bears between the underside of a spring
table K thereby pressing the frame downwards on the ribbon.
moving the apparatus back to its normal position over-rides the

At
position the supplementary frame does not bear upon the strip. The delivery
table K' has teeth formed at its inner end the points of which as the drum moves
round intermesh with the teeth of the combs & and release the strip therefrom.
its outer end the said table has also teeth formed on it against which the operator
can sever the perforated strip. To render the apparatus self-recording the
perforating drum C has a pawl m centred at nou an extension of the frame D and
which periodically acts against the spring a on a ratchet wheel L secured on a
dial M the face of which shews through the side of the case A.
If desired one or
two additional ratchet wheels L' L and indicating discs M', M² may be centred in
the box in which case the ratchet wheels L', L' are turned by means of fingers o, p,
on the ratchet wheels L, L'.
Under a modification illustrated in longitudinal section by Figure 3 and in plan
by Figure 4, the platen H instead of having the type arranged as at Fig. 1 has a
slot made in it into which a triangular or other shaped carrier t is inserted the said
carrier having different series of types on each of its faces. The carrier spindle is
centred on the platen and on one of its ends a thumb nuts is secured to enable it to
be turned as described from the outside of the case A the spring r locking it in
position after each turn is effected.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is
The combination of parts constituting the improved perforating, measuring,
dating or stamping apparatus with or without the addition of recording mechanism,
substantially as hereinbefore described with reference to the drawings annexed.
Dated this 18th day of September 1893.
