1, GEORGE JESSE PURSER of Trafalgar Works Palmer Street, Birmingham, in the
County of Warwick Manufacturer, do hereby declare the nature of this invention to
be as follows:-
"
"
This invention relates to an improvement upon type writers, known as the
Simplex in which the appliance or apparatus consists essentially of a long
rectangular frame, with a standing up rack upon one side, and an overhanging flange
at the other; and upon the said frame, a slide with an upright bracket, and a type
wheel slides longitudinally. The slide is provided with a yielding free end and a
tooth upon its underside, which engages with the rack; while the type wheel admits
of a vertical sliding movement, for bringing the type down upon the paper, and inking
the same from an inking roller above. This type wheel has pierced within its
periphery, holes, which come in front of the type, and respectively take upon a peg
carried by the slide, so as to determine the exact position of the type impressions,
upon the paper.
My invention relates to the feeding, or advancing forward intermittently, or con-
tinuously if necessary, the paper to be printed upon, at the end of the printing of each
line; that is, the advancing forward of the paper through determinate distances, for
the printing respectively of each successive line, as the printing advances; and my
said invention consists in placing longitudinally underneath the frame, or between an
upper plate, or a bar carried by an upper plate, and the lower frame, two or more
rollers, above one another, and working within fixed or yielding bearings, and between
these rollers, the paper is advanced, by the rotation in a forward direction of one of
the said rollers, preferably the lower one.
In carrying out my invention, I take a type-writer, constructed essentially as
aforesaid, and with the hed or frame pierced with a longitudinal opening; and
working within gaps and end bearings of the top frame, are two or more cylindrical
rollers placed at suitable distances apart, and in juxta position to the longitudinal
opening as aforesaid.
The bottoms of these rollers, stand out a little beyond the underside of the top

page_text: frame, so as to impress themselves upon the top of the paper to he fed or moved
forward; and immediately under the aforesaid top rollers, an under long roller is
situated, which works in end bearings, and is worked or rotated by a milled or other
head or turn at one end, and it is between these rollers, which are preferably situated
at the off or leaving side of the framing, that the paper to be fed forward, is advanced
through the distance of a line, at each movement given to the under roller, which is
carried by the under frame.
The top carrying frame which carries the upper rollers (or roller) is hinged at its
back end, while its other end is provided with a fastening or securing device, for
securing the top and bottom portions of the framing together.
The under roller which is the feed roller, may be provided with a single, double or
other number of longitudinal ribs or bosses, which grip the paper intermittently
between itself and themselves, and the undersides of the upper rollers.
Or the feed roller may carry an adjustable finger, which moves in front of a stop,
and determines and limits the feeding forward of the paper to the distance of a line,
and no more; or an intermittent line feed, may be made, by one or other of the
rollers, carrying a ratchet wheel, worked by a pawl arm, with a finger presser at its
end; so that on the pressing down or forward of the arm of the pawl as aforesaid, the
paper is advanced transversely across the machine to the extent of a line.
On relieving pressure, the pawl wipes over the teeth of the ratchet wheel, and
resumes its normal position.
The necessary distance of a line may also be determined by having the turn (which
rotates the roller) made in the form of a capstan wheel, so that the movements of the
sprockets thereof, determine the feed to be given. Or the said turn may be made
with points, angles or facets upon its periphery.
The rollers may be plain, but I prefer for them to be covered or coated with india-
rubber, caoutchouc or other like yielding material, so as to give a good grip upon the
paper.

page_text: I GEORGE JESSE PURSER of Trafalgar Works, Palmer Street, Birmingham in the
County of Warwick, Manufacturer, 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 improvement upon type writers, known as the
"Universal Simplex," in which the appliance, or apparatus, consists essentially of a long
rectangular frame, with a standing up rack upon one side, and an overhanging flange
at the other; and upon the said frame, a slide with an upright bracket, and a type
wheel, slides longitudinally. The slide is provided with a yielding free end, or flat
spring, and a tooth upon its underside, which engages with the rack; while the type
wheel admits of a vertical sliding movement, for bringing the type down upon the
paper, and inking the same from an inking roller above. This type wheel has
pierced within its periphery, holes, which come in front of, or are arranged before,
the type; and which said holes, respectively take upon a peg carried by the slide,
thus determining the exact positions of the type impressions, upon the paper.
My invention relates to the feeding, or advancing forward intermittently, or
continuously if necessary, the paper to be printed upon, at the end of the printing
of each line; that is, the advancing forward of the paper, through determinate
distances, for the printing respectively of each successive line, as the printing
advances and my said invention consists in placing longitudinally underneath the
frame, or between an upper plate, or a bar carried by an upper plate, and the lower.
frame, two or more rollers, above one another, and working within fixed or yielding
bearings and between these rollers. the paper is advanced, by the rotation in a
forward direction, of one of the said rollers, preferably the lower one.
In carrying out my invention, I take a type-writer, constructed essentially as
aforesaid, and with the bed or frame, pierced with a longitudinal opening; and working
within gaps and end bearings of the top frame, are two or more cylindrical rollers,
placed at suitable distances apart, and in juxta position to the longitudinal opening as
aforesaid.
The bottoms of these rollers, stand out a little beyond the underside of the top
frame, so as to impress themselves upon the top of the paper to be fed or moved
forward; and immediately under the aforesaid top rollers, an under long roller is
situated, which works in end bearings, and is worked or rotated by a milled or other
head or turn at one end; and it is between these rollers, which are preferably situated
at the off or leaving side of the framing, that the paper to be fed forward, is advanced
through the distance of a line, at each movement given to the under roller, which is
carried by the under frame.
The top frame, which carries the upper rollers, (or roller) is hinged at its back end,
while its other end is provided with a fastening device, for securing the top and bottom
portions of the framing together.

page_text: The under roller, which is the feed roller, may be provided with a single, double
or other number of longitudinal ribs or bosses, which grip the paper intermittently
between itself or themselves, and the undersides of the upper rollers.
I will now proceed to describe with reference to the accompanying drawing, the
manner in which the same is to be performed.
Figure represents in plan, an "Universal Simplex" type writer, provided with
paper advancing means, constructed according to my invention. The upper framing
is partly broken away, so as to exhibit a portion of the lower and advancing roller.
Figure 2 is a longitudinal vertical section, upon the dotted lines A B figure 1; while
figure 3 is a transverse vertical section upon the dotted lines CD. figure 1.
The same letters of reference indicate corresponding parts in the several figures of
the drawing.
a is a rectangular hinged top frame, and b is a lower or base frame, connected to
the aforesaid top framing, by a hinged joint a, whilst the other end is fastened by
a turn a³.
e, which
Sliding longitudinally upon the top framing a, is a type wheel c, mounted and
carried by an upright bracket d, whose lower end, is connected with a slide
works within a groove a', and under a flange a³, respectively.
The slide e, has a spring arm e², with a tooth e³, upon its underside, which
engages with the teeth of a two way standing up rack e.
The type wheel e, admits of a vertical sliding movement, for bringing the type down
upon the paper, and also for inking the said type from an inking roller f, placed above
the type wheel.
Running longitudinally, and fitted within bearings, in the lower framing b, is an
advancing rollery; and above it, in the same vertical plane, are two upper rollers h,
working upon pius or hearings, carried by the top framing a. The undersides of
these rollers, come upon, or approach near to, the periphery of the lower roller g,
which has a covering, or facing, of india rubber, in order that a sheet of paper i, fed
between them, shall be more readily gripped, and fed onwards, as the printing
proceeds.
It is not absolutely necessary, that the lower roller g, should be faced with rubber,
leather or other yielding material, but I find that in practice, such facings are
advantageous.
Instead of the surface of the roller, or the surfaces of the rollers, being faced with
rubber, or the like, the said rollers may be carried by yielding bearings, so as to
always give a uniform grip, to the papers fed between them.
The lower roller g, is provided at one end, with a milled head 2, by means of
which, it is rotated, for the advancing forward of a sheet of paper to be printed, or as
the printing proceeds.
In using the type writer, place a sheet of paper, between the upper, and lower
frames. by unfastening the one end, and turning the top frame upon its other, and
jointed end, and then refastening the said unfastened end.
The sheet of paper, which is under the type wheel, is printed, by bringing the
type wheel into position, and the holes pierced within its periphery, opposite a
pointed peg when the printing proceeds, on the reciprocation, and longitudinal
movement of the frame.
The paper is advanced, by turning the milled head g², to a distance equal to the
width of a line, or any space, which may be desired, to intervene between the lines
of printing.
The extended outer end or bearing, of the feed roller g, may carry a pointer,
which on the rotation of the roller, is made to move in front of a graduated scale,
or line dial, which is a fixture on the end of the carrying framing.
Figure represents an end elevation of an intermittent line feed, consisting of a
ratchet wheel. (carried at the end of the feed roller g) lever arm k, loosely
jointed at, pawl 1, guide slot m, in frame, and adjusting screw n; so that by
changing the position of the said screw n, within the slot m, the requisite line,
widths, or distances, can be obtained.

page_text: The feed is worked, by simply reciprocating the arm k, upon its joint centre,
between the end of the slot, and the stop.
The backward movement of the pawl, wipes over the teeth of the ratchet wheel,
while its forward movement, rotates the feed roller, to a distance equal to the
width of a line.
The back movement of the arm, is preferably effected, by a spring o.
:
The turn g may be made if necessary, in the form of a capstan wheel, with arms
at distances apart, equivalent to line spaces.
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,
First. In combination with a type writer, of the "Universal Simplex" kind, as
herein set forth, of one, two, three or more rollers, arranged and working sub-
stantially as, and for the purpose, as herein described and illustrated.
Secondly Determining line distances of motion, of the feed roller, or rollers, of
type writers, of the kind as herein described, of means as set forth in figure 4.
