Improvements in Type Writing and the like Machines.
I JAMES HAROLD BARRY of 4 Cadogan Terrace Victoria Park in the County
of Middlesex Engineer do hereby declare the nature of this invention to be as
follows:-
:-
My invention relates to improvements in type writing and the like machines,
and consists in the construction of the type bars or arms that hold or carry the
type, and in the working or actuating them by means of levers and revolving gear
attached to the said type bars and in the mode of forming the ends or heads
to which the type is attached or fitted; and also in the material or materials
for the construction of the drum or barrel against which the type strikes in
operation, and in a rapid means of printing or writing in colors.
To carry this into effect I construct my type bars or arms, that hold or carry the
type, to revolve. To obtain this I pass such arms or bars through at their upper or
lower ends a hollow tube pivot or similar device, and fitted with a revolving or
reversable gearing formed by a pinion or other toothed wheel fixed at one end
and working in contact with an annular toothed wheel or section or part of a
wheel or other similar device or devices for the purpose of revolving the type
bars, such as milled heads and milled rings, or by a locking device such as pins
secured to the bars, and working in slots or holes in or around the sectional
annular, or annular toothed wheel or ring, or vice versa; or I may use a segment
of an ordinary toothed wheel locking with the pinions aforesaid, or pins or other
suitable device. The type heads or pieces to which the type is secured may be
made to carry two, three four or more sets of type on the reverse side of each
other, or on two, three or more sides of the said bars or arms.
With this revolving or reversable gear it will be seen that I can use a less
number of bars and levers than at present employed, and be able to print or
write in six or seven different characters; an indicator shewing the letters, is
fixed in a suitable place.
As these type bars, are revolving bars I am able to bring any letter, numeral
or other character for use to the front and I secure it there by spring or other
catch. In the type writers at present employed there is when in operation a
constant clicking or striking noise. I propose to obviate this by making my rollers,
drum, or barrel of silicate cotton or slag wool or such like sound proof material,
with a suitable binding agent, or cork or a mixture of cork and rubber or sections
of cork bound together by gum or rubber and suitably solutioned or such like
sound proof material or materials or any mixture of thein for the purpose
aforesaid.
In order to write or print in different colors without removing the ribbons
from the machine I propose providing more than one ribbon, with their bobbins
working on or around a toothed bar, endless screw, or with or by a rack or other
such arrangements for moving the bobbins and ribbons, backwards and forward
into position for working or they may also be placed on a frame to be lifted on
or off at the will of the operator.

I, JAMES HAROLD BARRY of 4 Cadogan Terrace Victoria Park in the County
of Middlesex, 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 :-
My invention relates to improvements in type-writing and the like machines, and
consists in the construction of the type-bars or arms that hold or carry the type,
and in the working or actuating them by levers and revolving gear attached to the
said type bars and in the mode of forming the ends or heads to which the type is
attached or fitted, and also in the material or materials for the construction of the
drum or barrel against which the type strikes in operation.
To carry this into effect I construct my type-bars or arms that hold or carry the
type to revolve, and to obtain this I pass each arm or bar through at their upper
or lower end, a hollow tubed pivot or similar device, and fitted with a revolving or
reversible gearing formed by a pinion or other toothed wheel affixed at one end,
and working in contact with an annular toothed wheel or section or part of a wheel
or other similar device or devices for the purpose of revolving the type-bars, such
as milled heads and milled rings, or by a locking device such as pins secured to the
bars and working in slots or holes in or around the sectional annular, or annular
toothed wheel or ring, or vice versa, or I may use a segment of an ordinary toothed
wheel locking with the pinions aforesaid, or pins or other suitable device.
An
The type-heads or pieces to which the type is secured may be made to carry two,
three four, or more sets of type, on the reverse side of each other, or on two, three,
or more sides of the said bars or arms. With this revolving or reversible gear it
will be seen that I can use a less number of bars and levers than at present
employed and be able to print or write in six or seven different characters.
indicator showing the letters is fixed in a suitable place. As these type-bars are
revolving bars I am able to bring any letter, numerals or other character for use to
the front, and I secure it there by spring or other catch. In the type-writers at
present employed there is when in operation a constant clicking or striking noise:
propose to obviate this by making my roller or drum of silicate cotton or slag
wool or such like sound proof material, with a suitable facing agent such as cork or
a mixture of cork and rubber or sections of cork bound together by gum or rubber
and suitably solutioned, or such like sound proof material or materials or any
mixture of then, for the purpose aforesaid.
As will have been seen from the foregoing, I can either evolve the type-heads
or the type bars by different mechanism or means. I will proceed with the aid of
the accompanying drawings to describe the method therein set forth first for
revolving the type-head, secondly for revolving the bar.
Figures 1 and 2 Sheet 1, shew a side and front view of the type bar R with
type-head P and ratchet wheel A which is provided with four holes (assuming four
sets of types are to be used) on the bottom side, into which the pin J fits when the
required type is in position, the pin J being attached to, or made with a loose
sleeve H fitting freely around the bar R and kept in position by the spring e.
Figures 3 and 4 Sheet 1 shew pinions A Figure 3, and D Figure 4, to work
with and gear into quadrant or curved rack 6. 7. 8 & 9. Sheet 1.
To actuate this movement the knob or finger plate d Figure 6 Sheet 1 is pressed
inwards, when the quadrant or curved rack Figure 6 comes into gear with the
pinions A Figures 1 & 3 or D, Figure 4 and revolves the type-heads Pane quarter
turn, or a turn in ratio to the number of types on the type-head, when by the
application of the spring O Figure 6 Sheet 1 which is fixed between the frame of
the machine "a" Figure 6, and the knob or finger-plate d the quadrant or

page_text: curved rack comes out of gear back into its former position on releasing the
pressure.
At the same time and by the same movement resulting from the pressing of the
knob d the cam action N Fig. 8 forces out the pin J Figures 1 & 2 Sheet 1 from
the hole it is in until the turn given to the pinion A Fig. 1 by the lugs B Figs. 6
& 7 is sufficient and the spring Ô is released, the curved quadrant Fig. 6 with its
cam N Fig. 8 comes out of gear, the pin J becomes free to fix into the next hole in
the bottom side of the pinion A Figure 1 and 3 or D Figure 4 and secure the
head ready for striking.
It will be seen that by the whole of the revolving type-heads or bars being
arranged with their pinions A or D to come into gear with the curved rack
Figure 6 & 7 the one pressing of the knob or finger plate "d" will revolve them
all simultaneously, so that the characters letters or signs will correspond.
Figures 4 & 7 with their letters D & C shew a different form of pinion and rack,
to be actuated as before described, but may be made continuous or working
backwards and forward.
Figure 9 Sheet 1 is a cross section of Figure 8 and in which B is the curved
rack and N the cam aforesaid on its reverse side for actuating the pin J as before
described.
Figure 5 Sheet 1 shews the striking movement, being the finger plate or key,
f&l being fixed joints, the levers L working on them and actuating type-bar or
arm R Fig. 5 & 1.
Figure 1 is the fixed joint as at Figure 5.
Figures 12 & 13 Sheet 2 shews plan and side elevation of indicator.
Figs. 12 & 13 show plan and side elevation of the indicator worked by pressing
the knob d Fig. 6 when revolving the type bars-that is when the knob d Fig. 6
Sheet 1 is pressed, the lug M, Fig. 6 Sheet 1 working in the ratchet or cam t
Fig. 13 Sheet 2 actuates the revolving disc T of the indicator Figs. 12 and 13
Sheet 2.
The indicator moves one quarter turn at each stroke of the knob or finger
plate d Fig. 6 Sheet 1 : thus the letter numeral or sign on the type head in action
jor striking will be represented in the recess of the indicator as shown at T
Fig. 12 & 13 Sheet 2. Referring to Figs. 12 & 13 Sheet 2 the top plate V is
stationary, the plate T figured with the signs and numerals revolving as previously
described, by the gearing of the lug M, Fig. 6 Sheet 1 into the ratchet or cam t
Fig. 13 Sheet 2 underneath the revolving part T of the indicator and being
connected thereto.
For revolving type bar or arms S, I may make the same, or provide it with a
hollow tube or sleeve Q encircling it at its upper or lower end and having
trunions X Figs. 10 & 11 to work in a pivot on the frame.
The type-bar or arm S thus revolves inside the sleeve Q or hollow tube without
affecting any other part of the mechanism.
I attach the pinion at one end of the bar to be actuated by the curved rack as
before described and shown in the accompanying drawings.
Fig. 10 Sheet 2 is a side view and Fig. 11 is a front view of the sleeved end of
the type bar or arm.
S. Figs. 10 & 11 Sheet 2 is the type-bar or arm, Q the sleeve, X the trunions,
and W the pinion to be actuated by curved rack Figs. 6 & 7 Sheet 1. as before
described. I may also revolve these bars by a ball and socket or universal joint
arrangement. Figs. 16 & 17 Sheet 2 are a side elevation and section of the drum or
roller in which G is the silicate cotton or slag wool and E the facing agent of cork
or a mixture of cork & rubber I being the rod on and around which the drum
is built.
Whilst I prefer to arrange the materials for forming the drum or roller as
stated 1 desire to reserve to myself the right to differently arrange them, or to
use the silicate cotton or slag wool alone or in combination with any other suitable
material or materials.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it understood
that I do not confine myself to the hereinbefore means and mechanism for
revolving the type-bars, or heads, as there are other means of accomplishing the
same including an electrical and pneumatic action, but what I desire to secure by
Letters Patent is :-
1. In type-writing or the like machines the use and application of revolving
type-bars or type-beads actuated by the mechanism herein before described or
other means, for the purpose set forth.
2. In type-writing or the like machines, the use and application of a silent
drum or roller, composed of silicate cotton or slag wool in combination with cork,
or a mixture of cork & rubber, or the silicate cotton or slag wool by itself, or
in combination with other suitable material or materials.
3. Type writing or the like machines containing silent drums as described and
revolving type bars or heads with two or more types on the reverse sides of
such bars or heads.
