We, ALEXANDER SINCLAIR COCHILL of Moyne Road, Rathmines, Stationer and
JOHN ALEXANDER CAMERON RUTHVEN of Fritonville Road, Sandymount, Engineer,
both in the County of Dublin; Ireland, do hereby declare the nature of our invention
for "A MACHINE FOR CUTTING AND PRINTING STEPPED INDEXKS" to be as follows:-
Our invention relates to a machine for cutting stepped indexes and printing on
the successive steps successive letters which may be of two different colors:
We mount on a suitable frame a sliding table to which, by means of a treadle
working a pawl and ratchet motion, a step by step movement is given, each step
constituting an equal advance. In order to adjust the advance made at each step
to be an equal division of the depth of a page, whatever the total depth may be,
we connect the table to a lever to which tho step by step motion is given at
various distances from its fulcrum, so that the advance of the table at each step
which the lever makes is proportional to the distance of the connection from the
fulcrum of the lever. Above the table we mount in suitable guides at some
distance apart two vertically sliding bars, which are caused to reciprocate by the
action of the same treadle, that moves the lever step by step, these bars ascending
while the pawl is advancing the ratchet that moves the lever, and descending when
the pawl is making its back stroke. To one of these bars is attached the cutting
punch, which, in descending, cuts a step from the edge of the paper placed on the
table below it. To the other bar is attached a type wheel with suitable inking
apparatus, this wheel having on its axis a star-wheel that at every ascent of the
wheel turns it one division round. When the wheel descends, the type presented
at the lowest point impresses a letter on the paper placed on the table below
Thus, an operator holding the pages of the index, piled or bound together, under
the cutting punch, has them cut into successivo steps; and the step-cut pages,
being fixed under the type wheel, oach step is printed with its appropriate letter.
When it is desired to print the letters in two colors, as, for example, red and blue,
alternating, we make the type wheel with two rows of types side by side around
its periphery, and by means of a helical guide cause the type wheel to turn during
each ascent, half round the axis of the bar on which it is mounted, so that the types
of the two rows are presented alternately to the paper. Each row has in that case
its separate inking roller, one for each color.

DEVILICATION.
We, ALEXANDER SINCLAIR COGHILL of Moyne Road, Rathmines, Stationer, and
JOHN ALEXANDER CAMERON RUTHVEN of Fritonville Road, Sandymount, Engineer,
both in the county of Dublin, Ireland, do hereby declare the nature of our
invention for "A MACHINE FOR CUTTING AND PRINTING STEPPED INDEXES" 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 a machine for cutting stepped indexes and printing on
the successive steps successive letters which may be of two different colors.
We mount on a suitable frame a sliding table to which, by means of a treadlo
working a pawl and ratchet motion, a step by step movement is given, each step
constituting an equal advance. In order to adjust the advance made at each step
to be an equal division of the depth of a page, whatever the total depth may be,
we connect the table to a lever to which the step by step motion is given at various
distances from its fulcrum, so that the advance of the table at each step which the
lever makes is proportional to the distance of the connection from the fulcrum of
the lever. Above the table we mount in suitablo guides at some distance apart
two vertically sliding bars, which are caused to reciprocate by the action of the
same treadle that moves the lever step by step, these bars ascending while the
pawl is advancing the ratchet that moves the lever, and descending when the
pawl is making its back stroke. To one of these bars is attached the cutting
punch, which, in descending, cuts a step from the edge of the paper placed on the
table below it. To the other bar is attached a type wheel with suitable inking
apparatus, this wheel having on its axis a ratchet wheel that at every ascent of the
wheel turns it one division round. When the type wheel descends, the type presented
at the lowest point impresses a letter on the paper placed on the table below.
Thus, an operator holding the pages of the index, filed or bound together, under
the cutting punch, has them cut into successive steps; and the step cut pages, being
fixed under the type wheel, each step is printed with its appropriate letter.
When it is desired to print the letters in two colors, as, for example, red and
blue, alternating, we make the type wheel with two rows of types side by side
around its periphery, and by means of a helical guide cause the type wheel to turn
during each ascent, half round the axis of the bar on which it is mounted, so that
the types of the two rows are presented alternately to the paper. Each row has
in that case its separate inking roller, one for each color.
Fig. 1 of the accompanying drawings is a front view of a machine according to
our invention, Fig. 2 is a plan with part of the table broken away to shew some
of the mechanism below it, Fig. 3 is a tranverse section, Fig. 4 is a front view, and
Fig. 5 a side view, to an enlarged scale, of the type wheel and inker. A is the
table having at one part of its length a channel a faced with soft metal to receive
the stroke of the cutting punch the stem of which works up and down in the head
B, being made to descend by the downstroke of the treadlo C which is counter-
weighted at c. The downstroke of the treadle also causes descent of the type-
wheel D the stem of which works in the head E. By means of a rocking shaft F

page_text: and its arms the stroke of the treadle also moves a bar G carrying a spring pawl g
which engages with a ratchet rack on another bar H moving it step by step to the left
at each upstroke. The bar H by means of a pin h moves a two sided lever K, between
the sides of which can be slid by means of a screw another pink which engages in
a transverse slot, on the under side of the table A by shifting the pin k along
its slot the advance imparted to the table at each upstroke of the treadle can
be adjusted to suit various lengths of index steps. The stem of the type wheel D
carries a roller e which by descending and ascending in a cam slot of the head E
causes the stem of the type wheel to turn half round at every stroke. On the
typo wheel there are two rows of types alternating with each other, so that by the
half turn of the vertical axis the letters are printed in succession, the type wheel
itself being turned at every stroke one division by the pawl and ratchet d. Behind
the type wheel is a curved inking table L along which at every downstroke an
inking roller M is caused by means of the rack and pinion m to run, this roller
descending during the upstroke to ink the lowest types of the wheel D. For
alternating colours, two rollers M are used as shown.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
wo claim is
The construction, substantially as herein described and illustrated by the
drawings, of a machine for cutting and printing stepped indexes.
