PROVISIONAL SPECIFICATION.
Improvements in Copyholders for Typewriting Machines.
I, ELI B. BINGHAM, of Wellston, Ohio, U.S.A., Attorney-at-Law, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide simple mechanism whereby the docu-
ment being copied from by a typist is held in front of the operater and caused to
travel with the paper being written upon at any desired speed.
By this invention, two upright side-pieces are secured to the framework of the.
machine, adjacent to the ends of the platen, and are united at their upper ends by
a cross-bar. A roller, very similar to the platen,-is journalled in the side-pieces,
parallel to the platen, and is fitted at one end with a ratchet wheel corresponding
with a like wheel on the platen. The roller and the platen may be caused to
rotate at the same speed by a band running over corresponding pulleys mounted
at their ends. A small roller, suitably journalled, runs in contact with the roller,
first mentioned, to keep the copy in contact therewith and to feed it between the
guide-springs which are similar to those commonly used in connection with the
platen.
In order that the speed, at which the copy travels, may be varied with respect
to the platen, in case the spacing be different, the usual pawl-lever, for rotating
the platen, is lengthened and fitted with a pawl at its upper end to engago the
ratchet on the roller. The lengthening piece is clamped to the pawl-lever in
such manner that it can be raised or lowered, with relation to a scale thereon, so
that the pawl moves the ratchet one, two or more teeth at a time, as desired, or,
to disengage the pawl entirely.
Both the platen and the copy roller are provided with the usual scale, so that
the paper can be inserted to travel exactly in alignment with the copy.

I, ELI B. BINGHAM, of Wellston, Ohio, U.S.A., Attorney-at-Law; 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 copyholders and particularly to an attachment for
typewriters; the object of the invention being to provide a copyholder adapted
to be detachably secured to the carriage of any standard typewriting machine, to
automatically feed the copy with the feed of the paper being written upon.

page_text: A further object of the invention is to provide means for automatically feeding
one or more lines of matter being written to one line of the copy, or one or
more lines of the copy to one line of matter being written, or feeding the
copy and the paper being written upon equally.
Other objects and advantages accruing from my attachment will be revealed in
the specification and claims to follow.
The invention consists in the novel construction and arrangement of parts as
will be hereinafter pointed out.
In the accompanying drawings forming part of this application, Figure 1 is a
perspective view of a typewriter carriage with my copy-holder and feeder attached;
Fig. 2 an end view, shewing, in dotted lines, the copy-feed pawl out of engagement
with the ratchet teeth on the end of the feed roller; Fig. 3 a rear view of the
copy-holder detached from the carriage.
The same numeral references denote the same parts throughout the several
figures of the drawings.
Secured to the carriage 1 of the type-writing machine are two uprights 2 having
forked or slotted ends 3 and a set-screw 4.
The forked end sets over the said frame and is held in place by said set screws 4.
The top ends of the uprights 2 are joined by a cross bar or rod 5. This completes
the copy-holder frame.
The copy-feed roller 6 is a substantial duplication of the ordinary type-writer
platen 7, having a ratchet wheel 8 upon one end and a pulley 9 upon the other
end. A like pulley 10 is secured to the end of the platen-roller 7, and a belt 11
connects these pulleys.
A bar 12 is secured at each end to the uprights 2 and carries the paper table 13
in the rear of the copy-roller 6.
Springs 14 are secured at 15 to the bar 12 and engage the copy roller 6 and have
a scale guide 16 secured to them. Between the point of attachment 15 of the
springs and said scale guide is journalled a presser roller 17, between which and
the roller & the copy is fed equally with the platen 7 by turning the latter so that
with every movement of the platen the same movement is automatically imparted
to the copy-roller 6. The mechanism for varying the movement or feed of the
copy-roller 6 relative to the movement of the platen 7 consists of a lever 18 attached
at 19 to the line space lever 20, of the typewriter, and has a scale 21.
A pawl 22 is pivoted to the lever 18, and rests in the forked end of a con-
trolling rod 23, which is, pivoted at the other end to a clamp 24, adjustably
secured to the lever 18, so that when it is desired to change the movement of the
copy-roller relative to the movement of the platen the clamp 24 is adjusted
according to the scale 21, the scale being graduated in equal space to the teeth
of the ratchet 18.
When it is desired to have the copy-roller move equally with the platen as
herein before described, the clamp is run upward on the lever 18 until the pawl 22
will stand clear of the ratchet 8 and the copyroller is operated by the belt. The
latter may be dispensed with, and the pawl be adjusted to operate the copy-roller
even with the platen.
It will be observed that by the arrangement of parts shewn and described, the
copy is always in full view of the operator, each line being copied from stands
just above the scale guide 16. The copy is inserted into the holder exactly like
the paper to be written upon is in any of the standard machines and follows around
the copy-roller 6 under the rod or bar 5.
It is obvious that my holder may be applied to any standard machine and may
be attached and detached as desired.
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 I
claim is
(1) In a copy-holder and feeder for tpyewriting machines the frame adapted to
be applied to the carriage of the machine, the rollers in the frame, and a pawl

page_text: connected to the line-space lever of the machine to operate said rollers as set
forth.
(2) The combination with the copy-holder frame adapted to be applied to the
carriage of a type-writing machine, and the rollers in the frame, of a lever secured
to the line space lever of the machine and a pawl to operate the said frame rollers
automatically with the platen of the machine as set forth.
(3) The combination with the copy-holder frame adapted to be secured to the
carriage of a type-writing machine, and the rollers in said frame, of the lever
having a scale and secured to the line space lever of the machine, a pawl, a clamp
on the scale lever and a controlling rod forked to support and operate the pawl
and connected to the said clamp, as set forth.
(4) The combination with the platen of a type-writing machine having a pulley,
a copy roller suspended from the carriage of the machine and having a pulley and
a belt connected to the pulleys, of means for varying the movement of the copy-
rollers relative to the movement of the platen, comprising a scale lever fixed to the
line-space lever of the machine, a pawl pivoted to the scale lever, a clamp adjustably
secured to the scale lever, and a controlling rod forked to support and operate the
pawl and connected to the said clamp, as set forth.
