I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a type-writing machine which has the letters or type
arranged on a wheel and which differs from other machines of the same class in the
arrangement of a tilting frame which carries both the type wheel adjustable on
a fixed spindle and the fixed indicating disc and which, when tilted partially effects
spacing by advancing the carriage and only when fully tilted effects the printing
by the corresponding type the key causing the tilting and the advance of the carriage
effects the movement of a tooth rack required for the latter operation by sliding
against a cam-face of the said tooth-rack. The advance of the paper is effected by
means of a band.
On the base plate is supported a side-bearing the pivotted tilting frame said frame
being constituted by two side-standards and longitudinal guide rails and a fixed
spindle. The movement of the tilting frame is effected by means of a key supported
by a spring and having the shape of a double armed lever carried on a pin on the
tilting frame. The shorter arm engages with a cam-face or projection of the tooth
rack guided in the tilting frame a pawl on a carriage mounted on the rail engaging with
said rack. On the carriage there is supported a bracket pivotted about a stud said
bracket carrying the type wheel loosely mounted on the longitudinal spindle of the
tilting frame and a bevel wheel with which engages a second hevel wheel the spindle
of which is supported on the bracket which also carries the fixed horizontal or
substantially horizontal index wheel or indicating disc. The spindle passes through
the latter and is provided at the end with a pointer arranged in a guide under the
influence of a spring or hookshaped projection of said pointer engaging with the
toothed rim of the indicating disc having teeth projecting downwards. A spring
band provided with an ink-pad on its inner surface partially covers the type wheel
and supplies ink to the type as the wheel rotates. The paper is guided by means of
an angle bar moved by means of a band one branch of said angle bar being guided
in a sleeve and provided with divisions on its surface for the purpose of spacing lines,
the paper being secured to the wide surface of the other branch by means of a spring
clamp.
The working of the machine is as follows:-
Having secured the paper to the angle piece a spring rail guided in lugs on the
base plate is raised for the purpose of keeping the paper flat the carriage is brought
after disengaging the pawl into the position required and the desired letter is
found on the indicating disc by turning the pointer. Owing to this turning of
the pointer and with it of its spindle the bevel gearing causes the type wheel to come
into such position that the corresponding type is at the lowest point of the

page_text: type-wheel. By causing the hook of the pointer to engage with the teeth of the
fixed indicating disc the type wheel is locked in this position. With the left hand
the operating key is depressed as much as possible, whereby the tilting frame with
the type wheel is caused to incline and the desired type is printed on the paper
stretched flat on the base plate, the printing of the adjoining types being prevented
by means of a metal-shield provided with a hole for the selected type to pass through.
During the time that the desired letter is being found by turning the pointer with
the right hand the operating key is depressed with the left hand as far as necessary
to move the tooth rack to the extent of one tooth for the purpose of spacing, by
causing the arm of the key to engage with the cam face of said rack. During this
time only the carriage is moved the frame is not yet tilted. When the operating key
is released the tooth rack is returned into its original position by a spring
consequently the pawl engages with the next tooth. Then the frame is again tilted
by depressing the key to the full extent and the next type printed. The returning
of the frame into its original position is also effected by a spring.
It is clear that with a little practice the machine can be worked very quickly.
Owing to the simplicity of its construction it can be manufactured cheaply and does
not require expensive repairs. Moreover it has the advantage of the whole surface of
the paper being visible.

A communication from the Firm of BEGER & MARKWORTH, of Deuben, near
Dresden, in the Empire of Germany, Metal Goods Manufacturers.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, 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 type-writing machine in which the type which is
connected with the indicating disc by bevel gearing and rests adjustably on a slide
in a tilting frame which is adapted to be inclined by means of a key by one
hand in order to print the lowest or undermost type on the paper, while the
other hand moves the indicator for selecting the desired letter on the indicating
disc, the key, before tilting the frame, laterally moving a rack mounted on the
tilting frame and thereby the slide supporting the type-wheel, for the purposes
of spacing.
In the accompanying drawing
Fig. 1 is a plan of a type-wheel machine according to the present invention
Fig. 2 is a side elevation in section
Fig. 3 is a front elevation and
Fig. 4 is a detail view of the tilting device.
On the base-plate a is supported in side-bearings 6 the pivotted tilting frame c
said frame being constituted by two side-standards and a longitudinal guide-
rail c¹ and a fixed spindle c². The movement of the tilting frame c is effected
by means of a key d supported by a spring f and having the shape of a double-armed
lever loosely mounted on one of the pins or pivots of the tilting frame. The shorter
arm engages when depressed with a pin c¹ of the frame and thus inclines the latter.

page_text: Before the key comes into engagement with the tilting frame, its short arm slides
along a cam face e¹ of the rack e, carried on the tilting frame, with which rack
engages a pawl g of the slide h mounted on the rail c¹. On the slide or carriage h
there is supported on a pin í a double arm or fork k carrying on one side the type
wheel loosely mounted on the spindle c¹¹ and a bevel wheel m with which engages a
bevel wheel m¹ the spindle n of which is supported at the other end by the other
arm k, which also carries the fixed indicating disc o. The spindle n passes through
the latter and is provided at the end with a pointer arranged in a guide p under the
influence of a spring, a hook-shaped projection 8 of said pointer engaging with the
toothed rim of the indicating disc o provided with downwardly projecting teeth.
For the purpose of inking the types on the wheel there is arranged on the arm ka
springy curved part u which is faced with a piece of felt v, or with any other suitable
fabric, the latter being permeated with colour and held in contact with the passing
type.
For the purpose of guiding the paper there is arranged on the foundation plate a
a rail y under which the paper is pushed, so that it rests against the branches of the
angle piece w where it is held by a spring . One branch of wis guided in a socket
z and is provided with a scale corresponding to the space between the line. By
advancing the angle piece w the paper is each time caused to advance to the extent
of one line.
The working of the machine is as follows:-
Having placed the paper on the plate a the slide his brought into position
after disengaging the pawl g and the desired letter is found on the indicating
disc o and by turning the pointer say by the right hand. .Owing to this turn-
ing of the pointer and with it of its spindle n, the bevel gearing m m¹ causes
the type-wheel to come into such position that the corresponding type is at the
lowest point of the type-wheel. By causing the hook s of the pointer to engage
with one of the teeth t of the fixed indicating disco the type wheel is locked in
this position. With the left hand the operating key d is depressed as much as
possible, whereby the tilting frame c with the type wheel is caused to incline and
the desired letter is printed on the paper stretched flat on the base plate a, the
printing of the adjoining types being prevented by means of a metal-shield pro-
vided with a hole for the selected type to pass through.
During the time that the next desired letter is being found by turning the
pointer with the right hand, the operating key d is depressed with the left-hand
as far as necessary to move the tooth-rack e to the extent of one tooth for the
purpose of spacing, by causing the arm of the key d to engage with the cam face
of said rack. During this time only the carriage his moved, the frame c not
being tilted.
When the operating key d is released, the tooth rack e is returned
into its original position by a spring, consequently the pawlg engages with the next
tooth. Then the frame c is again tilted by depressing the key d to the full extent
and the next letter printed and so on. The return of the frame c into its original
position is also effected by a spring.
With a little practice the machine can be worked very quickly. Owing to the
simplicity of its construction it can be manufactured cheaply and does not require
expensive repairs. Moreover it has the advantage of the whole surface of the
paper being visible.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondents and in what manner
the same is to be performed, I declare that what I claim is :-
1. Typewriting apparatus in which the pointer on an indicating disc and the
type wheel are operated with one hand, the other hand effecting the spacing movement
and the printing of the selected letter, comprising a frame adapted to be tilted by
a key d, said frame carrying an indicating disc supported by a slide h laterally adjust-
able on a rail c¹ and a type-wheel connected with said disc by bevel gearing, and also a
toothed rack which is first moved to the extent of one tooth, when the key is depressed,

page_text: for the purpose of moving the carriage after which by the complete depression of the
key the tilting frame c is inclined and the selected letter printed substantially as
described.
2. The combination and arrangement of parts constituting the complete typewriting
apparatus substantially as described and illustrated in the accompanying drawings.
