A Paper-feeding Attachment for Type-writing Machines.
I, GEORGE LATHROP RAWDON, of 115 Superior Street, in the City of
Cleveland, County of Cuyahoga and State of Ohio, United States of America,
Telegraph Operator, for The Postal Telegraph Cable Company, 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 a device for feeding sheets of paper to typewriting
machines, and has for its object to facilitate the work by automatically operating
the feeder conjointly with the movement of the lever which moves the paper
under the platen roller of the machine, and the invention consists in the new
constructions and combinations of parts as hereinafter described and pointed out
in the claims.
In the accompanying drawing :-
Figure 1 is a perspective view of my new feeding device as seen mounted on a
typewriting machine in working order."
Figure 2 is a cross-section of the device through the middle of the rollers,
showing the connection of the feed mechanism with the impression roller of the
typewriter.
Figure 3 is a view of the inner face of one of the end pieces of the frame work,
showing the vertical grooves in which the bearings of a guide plate slides and its
means of self-adjustment.

impression or platen roller, and C is the feed roller parallel with said impression
roller. These are of the usual construction in typewriting machines. My
invention is described as follows:
DD are the end bars or plates of a frame which supports the working parts of
my device. E is a bar forming the base of the said frame to the ends of which the
said end plates D are firmly secured, and said base bar is provided with pins e e
which enter holes in the carriage frame. Said frame may also be stiffened and
strengthened by other rods or bars E'.
Fis a roller journaled to the forward part of the end plates D D, and G is a
similar shorter roller also journaled to the rear parts of the said end plates D D.
His a ribbon having its ends attached to the said rollers F and G and is made to
wind back and forth on said rollers, as and for the purpose hereinafter shown.
The rear roller G is made to rotate by means of a spring and train of gear for
taking up the ribbon as fast as it is paid off from the forward roller, as follows:
I is a frame attached to the side of the end plate D in which a gear wheel J is
journaled, having on its shaft a helical spring K, the outer end of which is attached
to the wheel for the purpose of operating said gear and the train of gear connected
thereto. L is a second gear journaled in the frame I, and meshing with a pinion
on the shaft of said first gear J. M is a pinion on the end of the shaft of the
ribbon roller G, and in mesh with the gear L, and derives its motion from the said
gear and spring as before stated.
N is a short roller journaled in a bar or frame O, pivotally attached to a
longitudinal rod O' in the lower part of the frame plates DD. Said roller bears
against the ribbon H with pressure derived from a spring P fixed on the rod O',
and is designed to hold the sbeets of paper lying between the coils of ribbon from
slipping.
Qis a guide plate located underneath the roller F, designed for guiding the
edges of the blank sheets of naner to the impression roller B of the typewriter.

page_text: Said guide plate is attached to a rod R having its ends supported in blocks rr..
sliding in vertical grooves S S in the end plates D D. Said guide plate is self
adjustingly held up against the roller by rubber or elastic cords tt, attached to the
blocks and secured to the top of plates D D.
q is a cushion block on the upper side of said plate Q which rests against the
ribbon and serves to guide the edge of the blank sheets of paper under the top
edge of said plate and guide them down on the ribbon to the impression roller B of
the typewriter.
U is a rod attached to the lower corners of the end plates D D, against which
the lower portion of the guide plate Q rests to keep it in position relative to the
ribbon as the roll of ribbon on roller F decreases in size.
The ribbon H passes from the roller F down and under the roller C, between
it and the impression roller B, and back up to the roller G, when the device is
placed on the typewriting machine.
The method of applying and using this device is as follows:
First. The ribbon is placed under and around the roller C, as seen in Figure 2
when the device is placed on the machine, and is then ready for operation. Next,
the blank sheets of paper to be written upon are inserted between the coils of the
ribbon on forward roller F, by taking the sheets, one at a time, and inserting their
upper edges under the roller next to the guide plate 7 with the left hand, and then
with the right hand rotating the roller by a crank or knob on the right hand end of
said roller shaft, and thus drawing the sheets in between the coils of the ribbon,
and continuing to fill in sheets successively until a sufficient quantity of sheets
have been inserted between the coils of the ribbon to last any desired length of
time.
Now the operator may proceed to use the machine, the operations of which will
also operate the feeder, and the sheets will be successively delivered to the machine
as the work progresses; the sheets falling away from the machine as fast as they are
freed therefrom. This device is especially adapted for telegraph operators receiving
messages by wire, as it saves the time of placing and removing paper on a type-
writing machine.
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:
In a paper feeding device for typewriting machines, the combination with the
impression and feed rollers of a typewriter, of a supporting frame mounted on the
carriage of the typewriter; rollers F and G journaled in said frame; ribbon H
attached to said rollers and passed under the feed roller C of the typewriter; a
spring K and gear train J, L, M, attached to the roller frame D D, and connected
and operating said ribbon roller_G; a spring actuated pressure roller N bearing
against rear side of ribbon roller F, and a self adjusting guide plate Q journaled in
grooves S S in the end plates D D; all constructed and combined to operate
substantially as described and for the purpose set forth.
Dated this 4th day of June 1894.
