I, HARRY WILLIAM HIGHLAM, of Glen Lyn, Sanderstead Hill, Surrey, Gentle-
man, do hereby declare the nature of this invention to be as follows: -
This invention relates to improvements in typewriting machines and it has
for its object to provide a means whereby the operator may easily and readily
ascertain the exact position of any given line on the paper in the machine
without displacing the roller or lifting the carriage supporting the said roller,
or, in such cases as those where the roller is neither rocked nor lifted and where
the writing is invisible owing to a carbon sheet being placed over it, obviating
the removal of the said carbon. In addition to the above purpose, the device
may be used to indicate when the bottom of the paper is reached, without rocking
the roller or raising the carriage as aforesaid. The invention may be applied
to any machine in which a roller is used.
In applying the device to a machine of the Remington type, I reduce the
diameter of the roller at the left hand end sufficiently to accomodate a band or
bands of metal or other suitable material upon which are stamped at equidistant
intervals two series of letters or numerals which may be differently coloured,
the total number of each series being equal to the number of teeth upon the
ratchet wheel by which the roller is actuated. The two series of numerals or the
like lie side by side, but are not identical as far as the position of each of the
said numerals is concerned, the same being so arranged that the same numerals
or letters in either series indicate a position which would be reached were the
roller actuated tooth by tooth through a certain predetermined portion of a
revolution. The amount of rotation indicated by the position of the same
letters or numerals is optional in accordance with the depth of the heading of
the paper being used, and, when once determined, can be fixed or made adjust-
able. A pointer is attached to any convenient part of the carriage.
From the foregoing, it will be evident that, when the operator desires to type
matters of which only a certain portion is to appear upon the original and the
accumulated matter of several additions to be consecutively typed upon paper
by means of a carbon, it is only necessary, when the first portion has been typed,
to release the pressure rollers acting upon the paper and withdraw the original
matter, holding the carbon copy and carbon sheet firmly against the roller.
Note the letter or numeral as the case may be, upon the left index or scale,
and rotate the roller backwards with the paper or papers until the corresponding
letter or numeral is reached on the other scale. A fresh sheet of paper can then
be inserted and run into the machine by means of the roller until the original
letter or numeral is under the pointer, when the typing may be resumed, the
additional matter being added to that already upon the carbon copy left in the
machine.
It is obvious that the number of copies and the period of inserting and

page_text: removing same may be varied at the will of the operator or the demands of
circumstances.

improvements in Typewriting Machines.
I, HARRY WILLIAM HIGHAM, of Glen Lyn, Sanderstead Hill, Surrey, Gentle-
man, 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 an improved adjustable position scale for typewriters
and it has for its object to provide an adjustable scale whereby the operator
may easily and readily determine the exact position of any given line on the
paper in the machine without displacing the roller or lifting the carriage sup-
porting the said roller, or, in such cases as those where the roller is neither
rocked nor lifted and where the writing is invisible owing to a carbon sheet
being placed over it, obviating the removal of the said carbon.
In applying the device to a machine of the Remington type I reduce the dia-
meter of the circular platen at the left hand end sufficiently to accomodate two
bands of metal or other suitable material upon which are stamped at equi-
distant intervals two series of letters or numerals which may be differently
colored, the total number of each series being equal to the number of teeth upon
the ratchet wheel by which the platen is actuated, the two series of numerals
or the like lie side by side but are not identical as far as the position of each of
the said numerals is concerned, the same being so arranged that the same
numerals or letters in either series when adjusted indicate a position which would
be reached were the roller actuated tooth by tooth through a certain
determined portion of a revolution. The amount of rotation indicated by the
position of the same letters or numerals is optional and readily adjusted in
accordance with the depth of the heading of the paper being used, and, when once
determined, can be fixed. A pointer is attached to any convenient part of the
carriage.
In the appended drawings illustrating the invention
pre-
Fig-is-a plan of part of the carriage of a machine showing the application
of the device thereto.
Fig. 2 is a front elevation of the device secured to the platen.
Fig. 3 is a rear elevation of the scale removed from the platen.
Fig. 4 is a side view of the scale attached to the platen.
Fig: 5 is a section of the scale.
Fig. 6 is a detached view of the component members of the scale.
Referring to the drawings a is the platen of the machine reduced somewhat
at a¹ to accomodate the circular plate "1" under cut or recessed upon its inner
face "2" to receive the end of the platen and provided with a horizontal
peripheral flange "3" upon which are stamped or otherwise produced a series
of numerals running consecutively from "1" to "33" or to any number more
or less in accordance with the number of teeth upon the ratchet by which the
platen is rotated.
The flange "3" is reduced at "4" and has formed upon such reduced portion
a number of recesses 5" one to each numeral upon the flange "3" and with
$6

which numerals the said recesses are in line (see Fig. 4). The plate "1" has
formed upon its inner face a boss "5" bored to receive the spindle 6 of the
platen to which spindle the said disc or plate 1" is secured by means of a
Screw 7" tapped into the said boss and bearing upon the spindle. Mounted
upon the reduced portion "4" is a ring "8" upon the periphery of which is
a horizontal flange 10" of a diameter corresponding to that "3" already
referred to as forming part of the disc 1." This latter flange has also indicated
upon it in any suitable manner and in a different color a series of numbers the
same as those upon flange "1." Upon the inside of the ring "S" is a pro-
jection 11" adapted when the two parts are placed side by side to engage with
one of the recesses "5" and thereby prevent any movement of the parts
irrespective of one another so long as they are together.

Upon the outside of the ring "8" is a dished washer "12" bored to permit

of the passage therethrough of the boss "6" and having upon its edge slots"
designed and arranged to coincide with slots 14" formed upon the inner edge
of the ring "8" and provided to permit of the insertion of the screws
which the plate is secured to the end of the platen w. Secured to the
washer 12 are a number of studs or projections 16 which pass through
the plate and between the heads "17" of which and the face of the said
plate are compressed spiral springs "18" which thereby serve to keep the two
parts of the scale always together the projection "11" as aforesaid then pre-
venting any movement of the parts independently of one another.

is a pointer of any suitable form and attached to the carriage a.
From the foregoing it will be evident that the position of the numbers upon
each of the two component parts of the scale may be adjusted relatively to one
another by pulling the part "8" by means of the milled portion 19" until
the projection "11" is free from its engagement with its recess when the said
part 8 may be freely turned in either direction and the adjustment readily
effected. The two series of numerals as aforesaid are preferably in different
colors.

From the foregoing it will be evident that, when the operator desires to type
matters of which only a certain portion is to appear upon the original and the
accumulated matter of several additions to be consecutively typed upon paper
by means of a carbon, it is only necessary, when the first portion has been typed,
to release the pressure rollers acting upon the paper and withdraw the original
matter, holding the carbon copy and carbon sheet firmly against the roller.
Note the letter or numeral, as the case may be, upon the left index or scale,
and rotate the roller backwards with the paper or papers until the corresponding
letter or numeral is reached on the other scale. A fresh sheet of paper can then
be inserted and run into the machine by means of the roller until the original
letter or numeral is under the pointer, when the typing may be resumed, the
additional matter being added to that already upon the carbon copy left in the
machine.
It is obvious that the number of copies in the one case and the point at which
the typing is commenced upon the page may be easily and readily varied at the
will of the operator in accordance, in the case of ordinary correspondence, with
the amount of space occupied by the note or bill heading as the case may be.
I am aware that similar devices to that herein described and illustrated have
been employed, but in such cases the relative positions of the two sets of numerals
with regard to one another, have been fixed for each scale and not adjustable at
the option of the operator; thereby to a great extent limiting the utility of the
device.
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. A position scale for typewriters comprising a disc "1" immovably attached

page_text: by screws or the like to the end of the platen of the machine and provided with
a peripheral flange, upon one part of which are stamped or otherwise indicated
a series of numerals or letters, the other part of the flange being reduced and
having formed upon the edge thereof a number of recesses to equal the numerals
or the like, and also provided with a central boss bored to receive the spindle
of the platen and secured thereto by means of a screw or the like, a ring,
also provided with a flange upon which are indicated numerals as in the pre-
ceeding case, and of an internal diameter to fit the reduced part aforesaid, an
internal projection adapted to be engaged at will with any one of the recesses
upon the first flange and a means such as a dished washer and compressed
springs to hold the two parts together and a suitable pointer secured to the
carriage of the machine, all arranged, constructed, and operating substantially
in the manner herein set forth and illustrated by the appended drawings.

2. The combination with a rotatable type writer platen of a scale on
end thereof composed of two independently revoluble members cach numbered
or lettered upon its periphery the whole device being secured to and rotating
with the platen substantially as herein set forth and illustrated by the appended
drawings.
3. A position scale for typewriters of the kind herein specified in which the
proportion of revolution of the platen represented by the relative positions of the
two sets of numbers or the like is variable at will, all arranged, constructed, and
operating substantially as herein described and illustrated by the appended
drawings.
