Improvements in Means or Apparatus for use in Printing Letters or
other Indications for the Indices of Books, and other purposes.
I EDGAR ALFRED GODDIN of 138 Brooke Road, Stoke Newington in the
County of London, Engineer, do hereby declare the nature of this invention to be
as follows:-
These improvements have reference to means, or apparatus for use in printing
letters, or other indications for the indices of books and other purposes. wherein
letters or other indications are printed in alternate, or equivalent arrangement of
colours, say one letter black as A and the next letter red as B and so on, and yet
the printing is effected rapidly and continuously.
These letters or indications are preferably formed of vulcanised india rubber
mounted on or secured to plates or surfaces of metal, whilst these again are borne
by slides or supports arranged with capability of sliding in slots or grooves or
guideways which extend radially from the central compartment to the periphery of
a wooden, or other wheel, or circular body of the apparatus. This central.
compartment contains the hub in which the axis rotates to which the handle or
support for the tool is attached.
Upon each slide, or type support is formed a projecting pin, or equivalent part,
and upon the hub and against the wheel and slides; and so as to engage the pins,
or equivalent parts on the slides, is mounted a plate, or disc, having on its inner
face a snail, cam, volute, or other eccentric or pattern groove, or surface into which
the pins engage, or by which they, or their equivalents are operated when the said
plate is turned relatively to the wheel so as to cause the respective slides and the
type surfaces carried by them, to be protruded, or withdrawn from their grooves,
more or less and thereby to increase, or decrease the pitch of the wheel, or - .the
relative spacings of the types apart. This turning of this plate may be effected by
a key, and the plate may be pressed to the wheel by a spring.
-
The inking of the respective types with their respective coloured inks is effected
by means of rollers, one to each colour each roller mounted on an axis borne by a
spring, or other arm, which arms also carry projecting parts which each come in
contact with correspondingly formed surfaces or patterns formed on, or applied to
the type plates and adapted to cause the colored ink roller to be lifted clear of the
type surface not to be inked by it.
In place of causing the protrusion and retraction of the slides or supports for the
types by a cam or eccentric or snail I may effect their in and out movements by.
means of springs radiating from a central support and each spring having some
convenient attachment to the particular slide or support as by a hole in the spring
taking on to the stud of the slide and when by a nut or equivalent part the arch,
with which each spring is formed is flattened, each such spring becomes lengthened
as regards the distance of the end from the central support and the slide to each
type pushed outwardly.
I prefer to affix to the snail, or equivalent part for regulating the movements. of
the slides an indicator adapted to cooperate with a scale so as to serve as a guide to
the operator in determining the amount of regulation desired.

Improvements in Means or Apparatus for use in Printing Letters or
other Indications for the Indices of Books, and other purposes.
I EDGAR ALFRED GODDIN of 138 Brooke Road, Stoke Newington, in the
County of London, 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 :-
These improvements have reference to means, or apparatus for use in printing
letters, or other indications for the indices of books, and other purposes, wherein
letters or other indications are printed in alternate, or equivalent arrangement of
colours say one letter black as A and the next letter red as B and so on, and yet
the printing is effected rapidly and continuously.
These letters or indications are preferably formed of vulcanized india rubber
mounted on or secured to plates or surfaces of metal, whilst these again are borne
by slides or supports arranged with capability of sliding in slots or grooves or
guideways which extend radially from the central compartment to the periphery of
a wooden, or other wheel, or circular body of the apparatus. This central
compartment contains the hub in which the axis rotates to which the handle or
support for the tool is attached.
Upon each slide, or type support is formed a projecting pin, or equivalent part,
and upon the hub and against the wheel and slides; and so as to engage the pins,
or equivalent parts on the slides, is mounted a plate, or disc, having on its inner face
a snail, cam, volute or other eccentric or pattern groove, or surface into which the
pins engage, or by which they, or their equivalents are operated when the said
plate is turned relatively to the wheel so as to cause the respective slides and the
type surfaces carried by them, to be protruded, or withdrawn from their grooves,
more or less and thereby to increase, or decrease the pitch of the wheel, or the
relative spacings of the types apart. This turning of this plate may be effected by
a key, and the plate may be pressed to the wheel by a spring. The inking of the
respective types with their respective coloured inks is effected by means of rollers,
one to each colour each roller mounted on an axis borne by a spring, or other arm,
which arms also carry projecting parts which each come in contact with corre-
spondingly formed surfaces or patterns formed on or applied to the type plates and
adapted to cause the coloured ink roller to be lifted clear of the type surface not
to be inked by it.
In place of causing the protrusion and retraction of the slides or supports for the
types by a cam or eccentric or snail I may effect their in and out movements by
means of springs radiating from a central support and each spring having some
convenient attachment to the particular slide, or support, as by a hole in the spring
taking on to the stud of the slide and when by a nut, or equivalent part the arch, with
which each spring is formed is flattened, each such spring becomes lengthened as
regards the distance of the end from the central support and the slide to each type
pushed outwardly.
I prefer to affix to the snail, or equivalent part, for regulating the movements of
the slides an indicator adapted to cooperate with a scale so as to serve as a guide to
the operator in determining the amount of regulation desired.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation of my improved apparatus.

page_text: Fig. 6 is a section taken on the line -y in Fig. 5.
Fig. 7 shews a side elevation and plan of one of the letter slides D without the
letter, E. Fig. 8 shews a side view and plan of the spring plate, F.
Fig. 9 is a diagram shewing the ink-rolls, G,.their lifting cams, H, and adjacent
letter plates, d.
Fig. 10 is the key for altering the position of the parts.
Figs. 11 and 12 are respectively, a side elevation and section of a modified form
of the expansible wheel, A; and Fig. 13 shews an edge view of another form of
letter plate.
The object of my improved apparatus is to enable indices or other single or
multi-coloured indications to be printed in different lengths with one tool, which I
effect by means of an expansible wheel supported between the bifurcated ends of a
forked holder having, at its other end, a suitable handle.
This fork also supports one, or more, ink-roll carrying arms,, which are capable
of movement about their pivotal connections.
The expansible wheel A, consists mainly of a guide-plate, C, having two rings,
formed upon the same side of it, which are divided so as to form guide ways for the
letter slides D; these slides have, at their outer ends, plates, d, which carry the
letters E, their overlapping portions, d, which engage the ink-roll lifting cams,
afterwards to be described, constituting the means by which the proper colour is
selected for the letter borne by the plate of which it is a part. These letter
slides, D, are cach provided with a pin, d', which, cooperating with the spiral
groove, b, of the scroll-plate, B constitute the means by which the wheel, A, is
expanded and contracted.
The scroll-plate, B, is furnished with a spiral groove, b, and a boss, b, which fits
the central hole, e', of the guide-plate C, and is held in that position by the spring-
plate F (Fig. 8) which is secured to the said boss by screws (not shown) which
enter the holes, and 6, the arms f¹ of the said spring-plate, F, being set down,
bear upon the back of the guide-plate C, permitting it to be rotated, against their
frictional resistance, upon the boss, b, but preventing its withdrawal; one of the
arms, x, is pointed and serves as a finger, which shews upon the graduated scale,
upon the back of the guide-plate, C, the length of index or other indication that
the machine will print in a given position.
The boss, b, is bored to receive a bolt or pin, L, which forms a bearing and is
held by the forked end of the holder M.
The arms, N and O, are each provided at one end, with a roll, carried in suitable
bearings and supplied with different coloured inks, these bearings consist of two
downwardly bent ears, between which is placed the pin about which the roll revolves,
one of these ears is longer than its fellow and has formed upon its lower edge a cam.
surface, which engages the over-lapping portions, d, attached to the letters that the
roll that this cam carries is not to ink and causes it to be lifted clear; the other
ends of these arms are connected to the fork, M, by the screws, n and o, about
which they are capable of movement, their outer euds being constrained to rest
upon the letters E, or the overlapping portions by the tension springs n¹ and o¹,
which are connected to the pins n² and m¹; and o2 and m2 respectively.
It will be seen by reference to Fig. 2, that the letter plates, d, are attached to
the slides, D, in such a way that their overlapping portions, d², which form part of
the ink-roll lifting device, lay in the plane occupied by the cam carrying the ink
roll, G, from which the letters, to which they are attached, are not to receive
their colour.
As the machine illustrated is constructed to print in two colours only, it is
convenient to attach those plates, which carry the letters that are to receive the
same colour, to their slides with their overlapping portions, d, pointing, to the
opposite side of the wheel to that to which the others point, but when more than
two colours are used the surfaces of the overlapping portions, d', are of varying
shapes (see Fig. 13) the form of each being such as to lift all the inking rolls but
the one from which the letter, to which it is attached, is to receive its colour, whose

page_text: cam is permitted to pass through a channel d³, laying in the same plane as that
occupied by itself; such a machine would have as many ink-roll carrying arms as
colours it printed.
In using the machine the operator, to adjust it to print the size required, should
hold the tool in such a manner as to prevent the scroll-plate, B, from moving and
then, by means of the key K (Fig. 10) whose projections, k, engage the holes, k,
on the back of the guide-plate C, move that part in the direction of one of the
arrows, to cause the slides to go "in or "out," according to his requirements,
until the finger, fx, points to the desired size on the graduated scale.
Having thus set the machine, he should place it on the edge of the book, or other
article to be printed upon, seeing that he begins in the correct place, which is
indicated by the mark, s, and wheel the tool along, until it has made one revolution,
which, in the case of a book, it would have done by the time the other edge was
reached.
It will be noticed that as the wheel is rotated the overlapping portions, or lifting
plates, d, of the letter-plates, d are caused to engage with the irregular cam
surface, H, of all those inking rolls but the one which is to ink the letter to which
it is attached, with the result that they are lifted clear of the printing surface, but
the one which supplies the right coloured ink.
The modified form of expansible wheel shewn in Figs. 11 and 12 consists of a
dise or guide plate C and its letter slides D, of similar construction to that illustrated
in Fig. 5, and a spring-plate R having as many radial arched spring arms as there
are letter slides, which is placed upon the boss T, after the washer t, and lastly the
plate, P, is screwed onto the said boss, T, and completes this part.
It will be found that by screwing the plate P further onto the boss, T, the arched
springs whose pointed ends enter corresponding holes in the letter slides, being
straightened, will have their outer ends forced to a greater distance from the centre
and so effect the expansion of the wheel; the washer, t, which is borne upon by
the inner ends of the radial spring arms, r, equalizing the pressure, caused by their
straightening, at each end of the letter slides.
The amount of expansion can be accurately gauged by the scale on the plate. P
which is used in conjunction with the mark on one of the spring arms.
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 [
claim is,
In an indexing tool, or implement, for printing letters, or the like indications, for
the use of bookbinders or others.
1. An expansible printing well, consisting of a disc, provided with a suitable
number of radiating guide-ways containing a series of slides, each of which is
provided with a letter, or other indication, at its outer end, and a pin, or stud, on
its side, which either enters a spiral, or volute groove formed upon the adjacent side
of a second disc, or engages with the outer end of one of a series of radiating arched
spring arms, substantially as set forth and shewn in the drawings.
:
2. The combination, or arrangement, and use of parts for effecting the inking in
one, or more, colours, adaptable to the varying positions of the printing surfaces,
consisting of arms, pivoted at one end to a suitable support and having at their
other extremities an inking roll, carried between two suitable ears, the underside of
one of which is of such a form as, on engagement with a lifting plate attached to
the letters or other signs it is not to ink, to cause the inking roll to be. lifted clear
of those letters, substantially as set forth and shewn in the drawings.
3. The arrangement, or combination, and use of parts for adjusting the distances
between the letters, or other signs, on the expansible wheel by the use of a rotatable
disc, nut or equivalent part, having applied to it either a scale moving under, or
about a suitable pointer, or any appropriate indicator cooperating with a scale,
substantially as set forth and shewn in the drawings.
4. The combination of an expansible printing wheel, having a scale by which its

page_text: circumference can be accurately gauged, with one or more ink-roll carrying arms
provided with cams that cooperate with parts of the expansible wheel, carrying the
printing surfaces, to effect the printing in different prearranged colours under the
varying conditions of the printing surfaces, substantially as set forth and shewn by
the drawings.
5. The general arrangement, or combination of parts of the tool so as to enable
them to cooperate together, as and for the purpose set forth.
