Improvements in Indexing Machines.
I, GLORGE CROYDON MARKS, of 18, Southampton Buildings, London, W.C,
Consulting Engineer and Patent Agent, do hereby declare the nature of this
invention to be as follows; -
I have heretofore invented and produced a machine for indexing the printed
margin of a book by cutting out notches down to the leaf to be indexed, the
notches being arranged in series and in then printing upon the bottom or base
leaf of each notch the appropriate index chaiacter or symbol and the present
invention relates to a more improved means for supporting and adjusting the
gouges and type adapted to cut out the notches and pint the index character
The work to be down economically requires that the series of notches be cut at one
time and that the index characters be printed at one time and this requires a
variety of adjustments of the gouges of knives and of the punting type in order
to meet the requirements of the work to be done and it is the object of this inven-
tion, primarily to provide for the different adjustments in a simple but effective
manner
The cutting knives or gouges and the punting type are used interchangeably in
the same support but I prefer to have one holder for the gouges and to have a
second holdei carrying the printing type so that the action will be successive
though this is not essential and after the notches are cut it is entirely possible
to remove the gouges and replace them by the printing type
I prefer to provide four supports upon the periphery of connecting disks or a
cylinder and two of these may contain the gouges and two may contain the printing
type or any disposition of the type and gouges may be made as the work may
requie
The support carries a series of blocks and these blocks are held in place by
set screws and may be adjusted in or out These blocks cairy in turn, either the
gouges or printing type, one to each block and these are held adjustably to the
blocks so as to be moved in relation thereto This adjustment of the gouges or
type is at right angles to the adjustment of the block and thus it will be seen
that both horizontal and vertical adjustment may be given the gouges or printing
type In order to give lateral movement the series of blocks are held by screws
extending lengthwise of the support and centrally thereof preferably These
screws are adjusted to shift the blocks laterally In order to vary the distance
between the blocks when this becomes necessary, I use interposed wedges or blocks
and in this way I can vary, the distance between blocks as the work may require.

I, GEORGE CROYDON MARKS, of 18, Southampton Buildings, Chancery Lane,
London, WC, Consulting Engineer and Patent Agent (being a communication
from Smith Nicholas Webb, of Grand Rapids, Michigan, in the United States of
America, Travelling Salesman) do hereby declare the nature of this invention
and in what manner the same 18 to be performed, to be particularly described and
ascertained in and by the following statement
This invention relates to indexing-machines of the class in which the indexing
character is printed or other wise placed on the margin of the leaf of a book,
and in order that the indexing character may be seen while the book is closed a
portion of the margins of adjacent leaves is cut away to form notches in the edge of
the closed book at the bottom of which notches the indexing character 18 exposed
The pai ticular object of this invention is to produce a bai in which are held
the cutting-knives of the printing-type, and the bar and its attachments are 80
arranged that the cutting-knives may be adjusted in any one of three directions
that is, so as to cut to a greater or less depth, as may be desired, so as to be located
along the edge of the book from the top of the leaf to the bottom of the leaf,
as may be desired, and so as to be adjusted across the book to cut farther back of
forward on the properly-arranged front edge of the book
In using the cutting and printing appliance herein described the book is properly
arranged for treatment under the gouges or printing-type
This arrangement
consists in clamping it firmly with the front maigin or front edge of the book
arranged on a slant or diagonally across the plane in which the moving knives
travel, and inasmuch as it is desuable to have the notches of about uniform depth
tis necessary to so adjust the knives with respect to the book that those of them
which cut the notches in the first part of the book shall be set farther back toward
the back edge of the book than those which cut the index characters at the latter
part of the book. It is also necessary that the intermediate knives be properly
adjusted to cut the intermediate notches between the first and last The knives
cannot be set in all cases exactly in line, because the index characters are not
dispersed through the book at uniform distances For instance, the character " "A"
might fill twenty pages, the character "B" twenty-five, and the character "C"
twenty-five For these characters the adjustment of consecutive gouges would be
substantially uniform, but the character "Q" would occupy only a single page,
while "R" and "S" following it would occupy perhaps thuty or forty pages In
this case the gouge which is to cut the notch foi the character "Q" must be set
only slightly forward of the gouge on knife which 18 to cut the notch for the
character "P," while the gouge which is to cut the notch for the character "R"
will be set considerably forward of the "Q" gouge, and this same irregularity of
adjustment of the consecutive gouges or knives will attend the use of the machine
at all times The adjustments are attained in the bar which holds the bank
of gouges or the bank of type, and this bar may be used with any one of several
actuating machines or devices I have therefore confined the illustration mainly
to a bar shown independent of the mechanism by which it is actuated, and for
purposes of illustration have shown it as connected with a rotary cylinder and
have indicated that the cylinder 18 set in a framework in which it is revolved and
reciprocated, but the bar might be readily actuated by other mechanism than that
indicated

page_text: In the drawings, Figure 1 is a longitudinal cross-section of the bar, showing
some of the central knife-holding blocks in position Fig 2 is a cross-section
through the block, as at XX of Fig 1 Fig. 3 shows an empty and a filled block
attached to a rotary cylinder Fig 4 indicates the position of the rotary cylinder
in the frame in which it rotates and reciprocates
A indicates a bar adapted to hold the movable knife or gouge holding blocks.
(The bar which holds the knives and the bar which holds the type are identical
in all respects, the only difference between the two being that knife-terminated
tangs are inserted in one block and type terminated tangs in the other) The bar A
consists of a strong frame-work of four corner posts or pillars a a¹ a² a³, between
which is a cruciform opening
At intervals there may be placed connecting-
webs bbb between the bars at those parts of it which are to be used at places
where great adjustment along the axis of the bar is not necessary At parts where
considerable adjusting along the axis of the bar is necessary the webs are
omitted
It 18
For purposes of clearness I will call that diameter of the bar which 18 along the
axis of the knife the "vertical" diameter, that diameter which is across the
diameter of the knife the "cross" diameter, and will speak of the adjustment
along the axis of the bars as "longitudinal" adjustment
The knife-tang 2 (or type-stem) is held in a block J The tang 18 round and
engages in a round hole 4, that passes vertically through the block 3
adjustable both by rotation on its own axis and vertically through the block and
is held in its adjusted position by a set sorew 3*, that enters the block on the
cross-axis of the bar The block 3 is adjustable across the bar by sliding it to the
desired position, and it is held in this adjusted position by a set-screw 4", that
passes through one of the pillars a' of the bai.
To provide for longitudinal adjustment wedges 5 are interposed between adjacent
blocks 3, the wedges being of any thickness desued, and the blocks 3 are held
together by set-screws 6, that are driven axially (or longitudinally) into the
bar through properly-threaded openings in the web plates 61 68 or through a
threaded block 6 These three means of adjustment enable me to set the knives
entirely independently, both as to depth of cut and as to the axial position they
will occupy and the cross position they will occupy and enables me to adjust them
to cut properly any character of book
Under some conditions of work, all the adjustments mentioned herein may not
be necessary, and I do not wish to limit myself in this respect

When the bar or knife is adjusted along its vertical axis its position is
changed laterally of the book to cut to different depths. when adjusted along the
стова diameter it will be moved forward or backward in relation to the book
and when adjusted along the "longitudinal" axis of the holding bar the knife
will alter its position with respect to the top and bottom of the book
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1 In combination with a series of cutting knives or type-bars, a holder with
means of adjustment whereby the knives or type-bars may be set towards the front
or back of the book to operate on the different leaves and whereby also the knives
or type-bars may be adjusted laterally of the book to operate at different depths,
substantially as described.
2 In combination with a series of cutting knives or type-bars a holder having
means of adjustment whereby the cutting knives or type-bars may be adjusted
either forward or backward in relation to the book, laterally thereof to operate
at different depths or towards the top or bottom edge of the book, substantially as
described.
3. In combination the bar having the cruciform opening, the block adjustably

page_text: held in the said opening to be set in different positions either longitudinally of
the bar or across the same and the cutting knives or type-bais adjustably held by
said block to cut to different depths, substantially as described
