PROVISIONAL SPECIFICATION.
Improvements in Type Writing Apparatus.
1, JAMES MICHAEL FARMER of Esher Villa, Belgrade Road, Hampton, in the
County of Middlesex, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
The invention has for its object improvements in that class of type writing
apparatus, in which an endless band passing round two extension and guide rollers
and provided with projecting type of india rubber is employed in combination with
a holder and a rack to facilitate selection of the type required.
According to my present invention I mount the said guide and extension rollers
on vertical axes carried by a fixed frame or support and I employ two exactly
similar racks fixed a short distance apart and between which the finger piece or
holder connected to the type band moves. A pin or stud projects on each side of the
finger piece or holder to drop into the notches in the racks when a type has been
selected. This arrangement is to ensure a true motion to the type hand and prevent
the same being stretched in such manner as to throw the type, when printing, out of
their proper position.
The type work between two inking rollers near the printing position.
In combination with the aforesaid fixed type frame I employ a moveable paper
carriage, which is caused to traverse across the type writer step by step as required
for each type to be printed and for the spaces.
This paper carriage is constructed and operated as follows.
Guides are fixed to the base of the machine and the frame or base of the paper
carrier fits accurately between such guides with capability of moving to and fro
therein.
On the base of the paper carrier is fixed a toothed rack and on a bracket fixed
to the base of the machine is mounted a hell crank spacing lever carrying on its
short arm a spring pawl, which acts in combination with the aforesaid toothed
rack so that, by depressing the long arm of said bell crank spacing lever, the
spring pawl is caused to take into a fresh tooth of the rack and on the return or
rising motion of the spacing lever, which is effected by a spring, the paper
carrier is caused to move the distance of one space or type across the type
writer.
The paper carrier proper consists of a rubber covered roller mounted in the
vertical arms of a bell crank frame, which latter is mounted on an axis at the
junction of the two arms of the crank; a spring presser, curved to fit the rubber
covered roller, acts to clip the paper firmly between it and the said roller; a
wheel or knob on the axis of the rubber covered roller is employed to rotate such
roller when the paper is required to be advanced for a fresh line of writing and a
star wheel is also fixed on said axis, which acts in combination with a spring pawi
to indicate when the paper has been advanced the proper distance.
The paper carrier frame carries a "printing" bar, which forces the paper against
the type when a bar extending from end to end of the said paper carrier frame
is acted upon by a "
printing" lever mounted on the fixed bracket carrying the
bell crank spacing lever acting in connection with the toothed rack. The spring
pawl carried by said bell crank spacing lever is provided with a finger piece, by
depressing which the said pawl can be raised from the rack for the purpose of
enabling the paper carrier to be freely moved back across the machine for the
commencement of a fresh line of writing.
دو
The finger pieces of the spacing and "printing levers are arranged so that
the latter overlaps the former a certain distance in order that, by depressing the

page_text: printing" lover, the spacing lever shall also be depressed, whilst the latter can,
when desired, be separately operated.

Improvements in Type-writing Apparatus.
I, JAMES MICHAEL FARMER of Esher Villa, Belgrave Road, Hampton, in the
County of Middlesex, 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, reference being had to the accompanying
drawings, and to the figures and letters marked thereon:-
The invention has for its object improvements in that class of type writing
apparatus in which an endless band, passing round two extension and guide rollers,
and provided with projecting type of india rubber, is employed in combination
with a holder and a rack to facilitate selection of the type required, and the invention
consists of novel arrangements and combinations of parts to secure the correct action
of the apparatus, and at the same time simplify the construction thereof.
Figure 1 is a plan of my improved type writing apparatus, Figure 2 is a front
elevation, Figure 3 is a side elevation, and Figure 4 is a cross section drawn on the
line 1. 1. of figure 1.
In all the figures like parts are indicated by similar letters of reference.
a is the base of the machine, b is the endless type band, and c. c are the guide and
extension rollers, which, according to my present invention, are mounted on vertical
axes c², carried by a frame or support d fixed rigidly to the base a. The upper part
of the frame or support d consists of a plate d¹, in each end of which is a slotted
hole d², in which the axes c² are adjustably fixed, thereby enabling the endless type
hand b to be properly strained and adjusted. I employ two exactly similar racks e, e,
fixed a short distance apart to blocks d³, fixed to the frame or support d, and
between which racks, the finger-piece or holder b¹ connected to the type band, moves.
A pin or stud 2 projects on each side of the finger piece or holder b¹ to drop into
the notches in the racks e, e, when a type has been selected.
This arrangement is to ensure a true motion to the type band, and prevents the
same being stretched in such manner as to throw the type, when printing, out of
their proper position.
The type work between two inking rollers f near the printing position.
In combination with the aforesaid fixed type frame, I employ a moveable paper
carriage, which is caused to traverse across the type writer step by step, as required
for each type to be printed and for the spaces.
This paper carriage is constructed and operated as follows:-
Guides 9. g. are fixed to the base of the machine, and the frame or base h of the
paper carrier, fits accurately between such guides with capability of moving to and
fro therein.
On the base of the paper-carrier is fixed a toothed rack i, and on a bracket j, fixed
to the base a of the machine, is mounted a bell crank spacing lever k, k¹, carrying
on its short arm k¹, a spring pawl, which acts in combination with the aforesaid
toothed rack, so that by depressing the long arm k of said bell crank spacing lever,
the spring pawl is caused to take into a fresh tooth of the rack i, and on the return
or rising motion of the arm k of the spacing lever k. k¹, which is effected by a
spring m, the paper carrier is caused to move the distance of one space or type across
the type writer.
The paper carrier proper consists of a rubber covered roller n, mounted in the
vertical arms o of a bell crank frame, which latter is mounted at the junction of the

page_text: two arms o. o¹ of the crank on a rod or axis o³, working in brackets fixed to
the base h of the paper carrier; a spring presser 9, curved to fit the rubber covered
roller n, and provided with spring arms bearing against the rod o³, acts to clip
the paper firmly between it and the said roller n; a wheel or knob n¹ on the axis
of the rubber covered roller n is employed to rotate such roller when the paper is
required to be advanced for a fresh line of writing, and a star wheel n² is also fixed
on said axis, which acts in combination with a spring pawl r, to indicate when the
paper has been advanced the proper distance for a fresh line of writing.
The paper carrier frame carries at the upper ends of the vertical arms o, a printing
bar o³, which forces the paper t against the type, when a bar o extending from end
to end of the said paper carrier frame, and fixed at the ends of the arms o¹ of the
bell crank frame, is acted upon by a printing lever u, mounted on the fixed
bracket j, carrying the bell crank spacing lever k. k', acting in connection with the
toothed rack. The spring pawl l, carried by said bell crank spacing lever k, kl, is
provided with a finger piece , by depressing which, the said pawl i can be raised
from the rack i, for the purpose of enabling the paper-carrier to be freely moved back
across the machine for the commencement of a fresh line of writing.
The finger pieces ³, u¹ of the spacing and printing levers k. k² and u, are arranged
so that the latter overlaps the former a certain distance, in order that by depressing
the printing lever u, the spacing lever k. k¹, shall also be depressed, whilst the latter
can, when desired, be separately operated.
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 in which an endless india rubber type band is
employed, the peculiar construction and combination of parts substantially as herein
shown and described.
2. In type writing apparatus in which an endless india rubber type band is
employed, the peculiar construction of parts for ensuring the true motion of the
type band, substantially as herein shown and described.
3. In type writing apparatus in which an endless india rubber type hand is
employed, the combination therewith of a traversing paper carrier, constructed
substantially as herein shown and described.
