Improvements in or relating to Typewriting Machines.
A communication from CHARLES SPIRO, of 146, Centre Street, in the City,
County, and State of New York, United States of America, Gentleman.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
Two objects are sought to be attained in these improvements, first, to arrange
the machine for tabulating figures, or writing anything in columns in such a manner
that an operation of the spacing key will cause the paper carriage to travel the
full distance required from one column to the next whether the distance between
the various columns be always the same or not. Secondly, to arrange the machine
so that it may suit writers of different heights or positions to enable anyone to see
the writing; this is effected by a special. tilting device as will be presently
described.
The column spacing device may be effected in various ways, but it has been
found that either of the following arrangements gives satisfactory results.
Secured in any convenient manner upon the carriage of the machine preferably
upon the paper table is a bar or equivalent numbered to correspond with the usual
paper scale; this bar is also provided with a number of tapped holes into any of
which the requisite number of screws can be inserted leaving their heads or ends
projecting. Or in place of these a rack with a suitable number of sliding stops or
a simple slide or slot with the requisite number of suitable stops could be employed.
Pivotted upon a fixed portion of the frame is a dog or stop adapted under suitable
circumstances to engage with the pins or stops previously described and the spacing
key (which may be either the margin release key commonly used upon the Barlock
machines, or any other suitable key, special or not) is connected by any convenient
arrangement of mechanism with this stop and also with that dog of the escapement
mechanism which is normally in connection with the escapement rack. The
operation is as follows: -When the key is operated the spacing stops having been
placed in their respective positions, the movable stop is pressed forward into the
line of the spacing stops and the dog removed from engagement with the rack
when the paper carriage under the influence of its spring slides along until the
movable stop engages with the first of the spacing stops thus stopping the carriage.
Upon the release of the spacing key the escapement dog engages with the
escapement and the movable stop passes out of the path. of the spacing stops.
For the next column the spacing key is again operated with a like result and so on
and it will be seen that by placing the spacing stops at the requisite distances
apart the positions of the columns of printed matter can be varied as required.
The arrangement above described may if desired be reversed the stop being fixed
upon the paper carriage and the spacing stops connected with a movable or
rotatable bar so that they can be turned into and out of the path of the stop upon
the carriage, the escapement dog being operated as already described.
It will be understood that the details of this mechanism can be easily varied
without departing from the spirit of this part of the invention.
For the purpose of altering the tilt of the typewriting machine I apply to any
suitable part of the frame-work preferably the middle of the back one or more
screws or equivalent adjusting apparatus preferably carrying an indiarubber

page_text: button at the end by moving which so as to project more or less past the bottom of
the frame the tilt of the machine can be varied as will be easily understood.

COMPLETE SPECIFICATION.
Improvements in or relating to Typewriting Machines.
A communication from CHARLES SPIRO, of 146, Centre Street, in the City,
County, and State of New York, United States of America, Gentleman.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of London,
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 :-
Two objects are sought to be attained by this invention, first, to arrange the
machine for tabulating figures, or writing anything in columns in such a manner
that an operation of the spacing key will cause the paper carriage to travel the
full distance required from one column to the next whether the distance between
the various columns be always the same or not. Secondly, to arrange the machine
so that it may suit writers of different heights or positions to enable anyone to see
the writing this is effected by a special tilting device as will be presently
described.
In the accompanying drawings which exhibit portions of the well known Barlock
machine to which this invention, although applicable to other machines, is specially
adapted,
Figure 1 is a perspective view of those portions of the machine necessary to the
understanding of the present invention,
Figure 2 is a cross section through a portion of the frame-work and
Figures 3 and 4 are two views of the division plate for the column printing.
Figure 5 shows a portion of the frame-work with the tilting attachment.
Figure 6 shows the tilting attachment itself, and
Figure 7 is a plan of the bracket through which the tilting screw passes.
Like letters indicate like parts throughout the drawings.
A is a portion of the frame-work which carries the paper carriage etc., B¹ being
the bar upon which the carriage slides. C is the usual escapement rack upon the
paper carriage and travelling with it and D and E are the two dogs which engage
with the rack; B are portions of the paper carriage. To effect the column
printing it is necessary that the paper carriage with the platen and paper should
instantly travel when desired the distance from one column to the next and not as
in ordinary typewriting from one letter to the next. This distance may vary
according to the width of the columns, some perhaps being wider than others. To
effect this movement it is first of all necessary to disengage the dog D of the
ordinary escapement mechanism from the rack C so as to allow the carriage to
freely travel until pulled up in the proper place by the special mechanism provided
for the purpose. G is the key-spacing bar connected by the link G' with the two
armed lever H pivotted at H¹ upon the lug A' attached to the frame A. The
bar H carries the plate H2 the free end of which engages with the pin D¹ of the
dog D as shown in Figures 1 and 2 in such a manner that when the end of
the plate H2 is raised which occurs when the key-lever G is depressed the latter
pulling down the first end of the lever H and so raising the second end and the
plate H2 the dog D is tilted into the position shown in dotted lines in Figure 2,
and consequently its tooth D2 is entirely disengaged from the rack C shown in
dotted lines in Figure 2, and consequently (the other dog E being normally held

page_text: out of engagement with the rack C by its spring E³) the carriage is free to move
and will move under the influence of its spring until stopped by some means other
than the dog D. This stoppage is effected in the following manner. The detent I
Figure 2 pivotted to the frame at I' is normally in the position shown in full
lines in Figure 2, being retained in that position by the margin rack bar K whic
is pivotted at each end as at K¹ in suitable brackets or lugs upon the frame of
the machine. The normal position of the rack bar K is horizontal as shown in
full lines in Figure 1 so that its forward edge engages with the arm or tail I² of
the detent I thus holding it in its normal position and compressing the helical
spring J Figure 2. The rack bar K is held in its normal horizontal position by
the link or equivalent device K2 which connects it with one end of the lever H
beyond the plate H2, and as that end under the influence of a spring or by the
weight of the plate H2 or otherwise normally remains at its lowest position the
rack bar K is retained in its normal position. When however the key lever G is
depressed and the other end of the lever H is also depressed and the plate end
raised the link K' in rising turns the rack bar K upon its pivot until it lies in the
vertical plane as shown in dotted lines in Figure 2. When it assumes this position
the rack bar K ceases to engage with the tail 12 of the detent I and the latter
turning upon its pivot has its nose or dog 13 projected into the path of the
[3
screw L screwed into or fixed upon any convenient moving part of the paper
carriage B. It will therefore be seen that if the dog 13 be in the position shown
in dotted lines in Figure 2 and therefore in the path of the screws L the carriage
when released from the dog D and travelling under the influence of its own spring
will be pulled up so soon as the first screw or other projection L engages with the
dog I³ and the carriage will be stopped. Consequently to settle the spacing of the
columns it is only necessary to insert the screws or equivalent L at suitable
positions upon the paper carriage which to facilitate this is bored with a number of
holes M Figure 3 into any of which these screws may be placed and at any desired
distances apart. For convenience in positioning these screws the bar N which is
fixed upon the paper carriage and into which the screws L are inserted is marked
upon its face with a scale corresponding with that upon the paper carriage so that
by noting the positions upon the paper scale where the columns are to come and
placing the pins against the corresponding numbers upon the scale N the proper
positions of the screws and therefore of the columns can be provided before the
work commences. It will be understood that the scale upon the bar N is merely a
matter of convenience and that the pins L may be employed without the scale;
also that I merely employ the margin rack bar K to control the detent I as a
matter of convenience as I may operate the said detent in some other convenient
manner.
When the key G is released the parts return to their normal positions the dog D
engaging with the rack C and the dog 13 returning out of the path of the pins L
so that the machine then operates in the usual manner until the key G is again
depressed when the same operation is repeated the dog I³ then engaging with the
next pin L and so on.
The object of the tilting device shown in Figures 5 to 7 is to enable the operator
to adjust the lie of the machine so that he can conveniently see over the arc or
casing of the machine so as to get a view of the writing as he proceeds, the reason
for this adjustment being that it is found that while one operator can easily see the
writing, another one not quite so tall cannot see it so clearly. The tilting device
consists of a screw or equivalent device O screwing through a bracket P attached
to the back of the machine so that when the screw is screwed through this bracket
it tilts up the back of the machine and tilts down the front thus projecting the arc
towards the operator and enabling him more easily to see over it. To facilitate
the working of the tilting device the machine may be pivoted or provided with
special legs or equivalent but in practice it is found that the Barlock machines as
usually constructed are suitable for the application of this tilting device. Figure 6
shows on a larger scale the screw O and bracket P the former having a milled

page_text: head O by which it can be turned: Figure 7 shows a plan of the bracket without
the screw.
The bottom of the screw may have a loose end or head O preferably
of indiarubber which may be loose upon the end of the screw and retained by a
pin O engaging in a groove O' in the end of the screw O, a washer O' affording
a bearing for the rubber head O².
Having now particularly described and ascertained the nature of this said inven-
tion as communicated to me by my foreign correspondent and in what manner
the same is to be performed, I declare that what I claim is :-
:-
1. A typewriting machine so constructed that upon the moving of an appropriate
key the ordinary escapement mechanism is disengaged so that the carriage is free
to travel and a special engaging or stop device is brought into the line of travel of
certain movable stops in such a manner as to arrest the movement of the carriage
at these stops.
2. In a typewriting machine the combination of the lever H plate such as H³
dog D and pin D' whereby the escapement mechanism is disengaged from the rack
of the paper carriage substantially as described and illustrated in the accompanying
drawings.
3. In a typewriting machine the combination with a lever such as H of a pivotted
bar such as K so arranged that when the escapement mechanism is disengaged
from the paper carriage rack a special dog or detent such as 13 is brought into the
path of pins or stops such as L whereby the paper carriage is arrested at the
appropriate points substantially as described and illustrated in the accompanying
drawings.
4. The combination with a typewriting machine frame of a screw or device for
tilting the machine substantially as described.
5. In a typewriting machine the combination and arrangement of parts
constituting the complete paper carriage releasing and arresting device substantially
as described and illustrated in the accompanying drawings.
