page_text: 1, MARSHALL ARTHUR WIER of 3 Palace Grove, Upper Norwood, in the County
of Surrey, Engineer do hereby declare the nature of this invention to be as follows:-
My present invention relates to improvements in that class of type-writing
apparatus patented by me and numbered 3080, 9120, 11478 of the year 1885, in
which india rubber, metal, or other type bands are employed for the purposes of
type-writing.
In the specifications of the above mentioned Letters Patent, the letters, figures &c.,
on the type band were shown and described as printing in a horizontal position by
various devices but according to the present invention I cause tho characters to be
printed in a downward direction upon the material to be printed upon.
The carriago for the type band consists of two thin Hat pieces of metal or other
suitable material held at a given distance from each other by a slip of wood or other
material so as to allow a flanged pulloy to be placed at each end between them on a
horizontal axis. Upon these two pulleys the type band is made to run by means of a
finger piece or holder attached thereto, which latter is also attached to a sliding bar
formed with notches on its raised edges corresponding in position and number with
the characters on the type band. A wire spring stop is employed to act in con-
junction with such notches so that when it takes into a notch in the said bar a letter
or type in line with such spring stop and corresponding with a similar one on the
index scale carried by such bar will be correctly placed at the printing position.
The type carriage is supported at a vertical angle, with capability of sliding upon
two parallel horizontal rods or bars by means of suitable pins, projections or fittings
gripping such bars or rods. A rack is at one end detachably connected with the
type carriage by means of a spring slot or otherwise and a pin in the carriage
whilst at the other end it passes through a guide slot formed in an angle finger
piece connected to the left ends of the parallel bars or rods. A wire or other spring
presses the rack down to the bottom of such guide slot, which is deeper than the rack,
so as to prevent accidental back action of the rack. The said rack, and consequently
the parallel rods and carriage, rest upon a wire or other spring which also acts as the
driver to the rack.

page_text: The parallel rods are jointed to two brackets or supports and the angle finger piece
works between two guides formed by a bracket fixed to the opposite end of the base of
the type writer. The type carriage is provided with two inking rollers which supply
ink to the type at points near to the printing position.
The object of making the type carriage detachable from the rack is to enable the
said carriage to be readily slid off from the right end of the parallel rods or bars and
another carriage with different characters put in its place.
The paper is held in position by springs or by a spring bar clamping it down on
to the base of the instrument.
For writing on books or surfaces which cannot be placed in the type writer
I construct the instrument without a separate base and in such manner that the
instrument can be placed upon the material to be printed upon; for this purpose
I connect the brackets, carrying the axes of the parallel rods or bars, with the guide
bracket either by rods or strips of metal or by making the said brackets and strips of
metal in one piece leaving a space or slot parallel with the parallel rods or bars and
into or through which the printing takes place. Suitable regulating stops are
employed to adjust the depth to which the angle finger piece can be depressed and
consequently the pressure given to the type on the paper or other surface to be
printed upon.

page_text: Improvements in Type-writing Apparatus.
I, MARSHALL ARTHUR WIER of 3 Palace Grove, Upper Norwood, in the County
of Surrey, Engineer, 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, reference being had to the accompanying drawings
and to the figures and letters marked thereon, in which :-
Figure 1 is a side view, Figure 2 a plan, and Figure 3 a longitudinal section of my
improved type writing apparatus. Figure 4 is a cross section on the line 1. 1. of
figure 3. Figure 5 is a cross section on the line 2. 2. of figure 3. Figure 6 is a cross
section on the line 3. 3. of figure 3 showing the lower end of the type carriage, and
Figures 7 and 8 are respectively an underside view and a longitudinal section showing
the method I adapt for connecting the ends of the type band.
In all the figures like parts aro indicated by similar letters of reference.
My present invention relates to improvements in that class of type writing
apparatus patented by ine and numbered 3080, 9120, 11478 of the year 1885, in
which india rubber, metal, or other type bands are employed for the purposes of type
writing.
In the specifications of the above mentioned Letters Patent, the letters, figures, &c.,
on the type band were shown and described as printing in a horizontal direction
by various devices, but, according to the present invention, I cause the characters to
be printed in a downward direction upon the material to be printed upon.
The carriage for the type band a consists of two thin flat pieces b. b. of metal or
other suitable material, lield at a given distance from each other by a slip 1 of wood
or other material, so as to allow a Hanged pulley 62 to be placed at each end between
them on a horizontal axis 63. Upon these two pulleys 626 the type band a is mado
to run by means of a finger piece or holder af attached thereto, which latter is also
attached to a sliding index bar a formed with notches a³ on one of its edges
corresponding in position and number with the characters on the type band a.
A wire spring stop e is employed to act in conjunction with such notches a³ and
with characters on such index bar, so that, when it takes into a notch in the said
bar,.a, a letter or type on the type band a corresponding with that on the index. scale
in line with such spring stop c will be correctly placed at the printing position.
The type carriage bis supported at a vertical angle, with capability of sliding upon
two parallel horizontal rods or bars d. d. by means of a carrier provided with
suitable pins, projections, or fittings & gripping such bars or rods.. A rack e is at one
end detachably connected with the type carriage by means of a spring slot e¹, or
otherwise, and a pin 66 in the carrier 6, whilst at the other end it passes through a
guide slot d formed in an angle finger pieco d' connected to the left ends of the

page_text: parallel bars or rods d. d.
A wire or other spring presses the rack e down to the
bottom of such guide slot 2, which is deeper than the rack e, so as to prevent
accidental back action of the rack. The said rack e, and consequently the parallel
rods d. d. and carriage b, rest upon a wire or other spring g, which also acts as the
driver to the rack e, which latter is provided with a pin stop e² to prevent it from
passing accidentally through the guide slot d². g. is a hook or stop to limit the
upward motion of the spring driver g and thereby prevent its moving the rack e more
than one tooth at a time.
The parallel rods d. d. are jointed to two brackets or supports h. h. and the angle
finger piece d¹ works between two guides i. i formed by a bracket fixed to the
opposite end of the base of the type writer. The type carriage b is provided with
two inking rollers k. k. which supply ink to the type at points near to the printing
position.
The object of making the type carriage detachable from the rack e is to enable the
said carriage to be readily slid off from the right end of the parallel rods or bars d. d.
and another carriage with different characters put in its place.
The paper
is held in position by springs or by a bar clamping it down on to the
base of the instrument, such bar being connected to two pivotted spring arms l',
which permit it to be moved to facilitate the placing of the paper under the same.
The type band a has its two ends connected to plates a, a, which are connected
together adjustably by a screw a passing through a slot in plate at and screwing into
the plate a³.
For writing on books or surfaces which cannot be placed in the type writer, I con-
struct the instrument without a continuous separate hase j, and in such manner that
the instrument can be placed upon the material to be printed upon; for this purpose
I connect the brackets h. h. carrying the axes of the parallel rods or bars d. d. with the
guide bracket i, either by rods or strips of metal or by making the said brackets and
strips of metal in one piece, leaving a space or slot parallel with the parallel rods
or bars, and into or through which the printing takes place. Suitable regulating
stops m. m. are employed to adjust the depth to which the angle finger piece d¹ can
be depressed, and consequently the pressure given to the type on the paper or other
surface to be printed upon.
The instrument is operated as follows:-
To place the paper or other material in position to be printed on, the parallel guide
rods d. d, together with the type carriage band parts connected therewith, are lifted
up. free from the base j, upon which the paper or other material to be printed on is
placed; the spring barl is turned somewhat away from the base of the instrument
and the paper introduced under the same, after which the said bar is again placed in
the position shown in the drawing figure 2, and the paper properly adjusted. The
typo carriage is then slidden to the desired starting point by pulling the rack bar e to
the left; for the beginning of ordinary lines this is regulated by the stop d³ on
one of the parallel guide bars d. d. The parallel guide bars d. d are then brought, or
allowed to fall back into their normal position; the index bar a² is then slidden up or
down, by means of the finger piece or holder a¹, until the desired letter thereon and
its notch come under the spring stop c, the angle finger piece d' is then depressed by
the finger of the left hand. The first part of this action causes the rack e to be moved
one tooth to the right by means of the spring driver-g, thus effecting the spacing of
the letters; on continuing to depress the angle finger piece d' the type at the printing
point P is printed upon the paper or other material underneath it. Upon allowing
the springy to raise the parallel guide bars d. d. and type carriage to their normal
position, the spring driver g takes into the next tooth of the rack bar e, the springf
holding the rack bar e in position and preventing it returning or sliding back; this is
effected by the spring pressing the rack bare down, so that one of its teeth acts
against the edge of metal at the lower part of the slot d² in the angle finger piece d'.
The words are spaced by simply depressing the finger piece d' sufficiently to allow the
spring driver g to move tho rack e the distance of one tooth, but not sufficiently far to
cause the printing of the type.

page_text: 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 Type Writing Apparatus, the peculiar construction, combination, and
arrangement of parts substantially as herein shown and described.
2. In Type Writing Apparatus in which type bands are used, the peculiar con-
struction and arrangement of parts whereby the printing is effected in a downward
direction by depressing the parallel guide rods together with the carriage and type
band thereon substantially as herein shown and described.
3. In Type Writing Apparatus in which type bands are used, the sliding notched
index bar connected to the type band, and a spring stop acting with such notched.
index bar for the purpose of securing the accurate adjustment of the character on the
type band to the printing position and of holding it in such position during the
printing operation substantially as herein shown and described.
4. In Type Writing Apparatus in which typo bands are used, removeably mounting
the type carriage on guide bars and means for readily connecting and disconnecting
the same with the rack bar substantially as herein shown and described and for the
purpose stated.
