PROVISIONAL SPECIFICATION.
An Improvement in or relating to Type-writing Machines.
I ADOLPH EDWARD VIDAL, of 20 Central Hill, Upper Norwood, in the
County of London, Gentleman do hereby declare the nature of this invention to be
as follows:-
This invention has for its object to provide means for ensuring a proper margio
being left at the bottom of the sheet of paper.
According to this invention, I cut a slot or opening in the paper plate or table.
At the back or front of said slot 1 pivot an arm, so that one end shall come
against the paper. The other or tail end of the said arm (or an additional arm
fixed on the same rod) extends back sufficiently far to actuate a sound or sight
signal, either directly or indirectly, when the bottom of the paper is drawn away
from the end of the first mentioned arm.
1 provide suitable means for keeping the paper pressed against the aforesaid
arm.
According to one way of carrying out this invention I cut a slot, at the bottom
of the paper plate or table, and I pivot at the back of this slot an arm in such a
way that one end shall extend through said slot, and the opposite end shall rest on
the release bar or other suitable part of the carriage, after the paper has been
drawn from that end of the arm extending through the slot.
Thus when the
away
carriage is being drawn back for the purpose of commencing a fresh line of
writing, the back or tail end of the aforesaid arm will come against the striker of
the bell fixed to the machine, and give the desired signal. I fix an additional
plate, over the paper plate, having a slot or opening cut therein, corresponding to
the aforesaid slot or opening in the paper plate.
Instead of having a bell or other sound signal, I may have a sight signal or a
combination of the two.
Dated this Second day of December 1895.
COMPLETE SPECIFICATION.
An Improvement in or relating to Type-writing Machines.
I ADOLPH EDWARD VIDAL of 20 Central Hill, Upper Norwood in the
County of London; Gentleman, 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 has for its object to provide means for ensuring a proper margin
being left at the bottom of the sheet of paper.
According to this invention I cut a slot or opening in the paper plate or table.
At the back or front of said slot I pivot an arm, so that one end shall come against
the paper. The other or tail end of the said arm (or an additional arm fixed on
the same rod) extends back sufficiently far to actuate a sound or sight signal,
either directly or indirectly, when the bottom of the paper is drawn away from the
end of the first mentioned arm; I provide suitable means for keeping the paper
pressed against the aforesaid arm.
According to one way of carrying out this invention I cut a slot at the bottom

page_text: of the paper plate or table, and 1 pivot at the back of this slot an arm in such a
way that one end shall extend through the said slot, and the opposite end shall
rest on the release bar or other suitable part of the carriage, after the paper has
been drawn away from that end of the arm extending through the slot. Thus
when the carriage is being drawn back for the purpose of commencing a fresh line
of writing, the back or tail end of the aforesaid arm will come against the striker
of a bell fixed to the machine and give the desired signal.
I fix an additional plate over the paper plate, having a slot or opening cut
therein, corresponding to the aforesaid slot or opening in the paper plate.
Instead of having a bell or other sound signal, I may have a sight signal or the
two combined.
And in order that my said invention may be better understood I will now proceed
to describe the same with reference to the drawings accompanying this specification
in which :-
Fig. 1 is an elevation of the paper plate or table such as is used in the Yost
machine, having my invention adapted thereto.
Figure 2 is a vertical section of same shewing also the roller in the carriage.
Fig. 3 is a plan of the back portion of a machine of the same type shewing two
positions in either of which the indicating bell mechanism may be fitted.
Fig. 4 shews back elevation of bell and striker fitted to same machine.
Fig. 5 shews elevation of a paper plate or table of a Remington machine with
my invention adapted thereto.
Fig. 6 side elevation of same.
Fig. 7 shews modification of my invention on a plate similar to that shewn
at Fig. 1.
The same letters denote the same parts in all the views.
With reference to Figs. 1 and 2, a shews the paper plate or table of the
machine, shews an extra plate fixed over the ordinary one a sufficient space being
left between the two plates for the sheet or sheets of paper to pass. c shews a
slot cut in the two plates a and b. d shews an arm or tongue to which is fixed a
rode (shewn dotted) such rod fitting loosely into short tubes ff so that the arm
or tongue d may be pivoted at these points in order that the said arm or tongue
may escillate freely for the purpose hereafter described.
With reference to a modification shewn at Figs. 5 and 6 instead of having the
extra plate b, I fix a wire b¹ across the plate a, to which a fork piece c' is attached.
The arm or tongue d is bent as shewn at Figure 6 in this case and passes through
a slit in the upper portion of the paper plate a. This system would be found more
suitable for machines of the "Remington" type than that before described.
At Figure 7 is shewn another modification, in which the plates a and b are
arranged similarly to those shewn at Figures 1 and 2, but the rod e extends along
the whole length of the plate a, and is bent up at e¹ to act as striker to the bell n,
which in this case is fixed to the plate a, by means of an arm h. The rod e turas
in the tubes ff, fixed to the paper plate a, and this rod is cranked as at d', and is
intended to take the place of the arm or tongue d, shewn in the other views.
The bell arrangement with reference to the systems shewn at Figs. 1 and 5, is
represented at Figs. 3 and 4. In these figures i is a clamp, which takes on to the
back of the machine, this clamp is held in position by the screw k, on to this
clamp is pivotted the striker 1, at m, n is the bell, secured to one end of the wire o,
the other end of which wire is fixed to the clamp piece i.
I might form the clamp piece i, as shewn dotted in Figure 3.
shews the sheet or sheets of paper.
The action is as follows:-
Supposing the paper r to be inserted between the plates a and b, Figures 1
and 7, or between the plate a and the wire b¹ in Figure 5, and brought under the
rollers of the machine in the ordinary way, it passes between the arm or tongue d
and the plate bor the forked piece b¹ respectively, and thus keeps the arm or
tongue d in a raised position, as shewn at Figures 2 and 6 in full lines.

page_text: The consequence is that the tail end of the arm or tongue d passes clear of the
striker 7, when the carriage is drawn back to commence a fresh line of writing.
In the case of the mechanism shewn at Fig. 7, the striker is kept away from the
bell. As soon as the bottom of the sheet or sheets of paper is or are drawn past
the end of the arm or tongue d, the tail or opposite end of such arm will

system shewn at Figs. 1 and 2 is applied to a Yost machine, this tail will rest on
the release bart see Fig. 2. When arranged as shewn at Figs. 5 and 6 the
tongue or arm d will be held in the lower position, shewn dotted at Fig. 6, through
a part of it coming into contact with the forked piece c¹.
Thus as the carriage is drawn back, to commence a fresh line of writing, the
tail end of the arm d will catch against the end u of the striker l, and after
pulling it for a short distance, will release it, so that it will strike the bell, thereby
indicating that the writing is within a certain distance, say an inch, from the
bottom of the sheet. If less margin is required at the bottom of the sheet, one or
more lines can be written before numbering. There is no risk of forgetting, and
writing beyond the bottom of the page, as each time the carriage is drawn back
the bell will ring.
In the case of the arrangement shewn at Figure 7, when the bottom of the sheet
has passed the tongue d', the striker / will fall onto the bell.
I prefer to make the arm or tongue of thin spring steel, for the sake of lightness,
so as not to interfere with the insertion of the paper.
It is obvious that instead of indicating when the bottom of the paper is nearly
reached, by means of a sound signal, I might do so by means of a sight signal,
and this might be effected by causing the tail end of the lever to catch against a
signal rod, pivotted to the back of the machine, so as to turn the said rod up in
view of the operator or I might combine both sight and sound signal. I have
not thought it necessary to shew this sight signal on the drawing, as the method of
operating it is so obvious from the foregoing.
Instead of clamping the bell mechanism on to the machine, it may be fitted to
the same in the course of manufacturing the machine.
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. The improvement in or relating to type-writing machines, substantially as
and for the purpose set forth.
2. In type-writing machines, the combination with the paper plate, of a pivotted
arm or tongue and a slot in the paper plate, so that a signal may be actuated after
the bottom of the paper has passed the end of said tongue or arm, either directly
or upon the carriage being drawn back to commence writing a fresh line.
3. In type-writing machines, the combination with the paper plate of a pivotted
arm or tongue, slot in the paper plate, and means for keeping the paper pressed
against that portion of the arm or tongue projecting through the slot, so that the
tail end of said arm or tongue will be kept raised until the bottom of the paper is
drawn past the other end, for the purposes set forth.
Dated this Second day of September 1896.
