Improvements in Page-foot Indicators and Alarms for Type-writing
Machines.
I, FRANK WALDEN STANLEY, of No. 310 Washington Avenue, in the City of
Brooklyn, King's County, in the State of New York, United States of America,
Clerk, do hereby declare the nature of this invention to be as follows:-
It is common to employ means for indicating when the end of each line is
approaching. My improvement indicates in a somewhat analogous manner when
the writing has approached the bottom of the sheet.
In what I esteem the most complete form of the invention, I employ two
indicators, the first arranged to give warning when only about the proper space remains
for the closing lines of a letter, and the second to indicate when the bottom is so
much more nearly reached that there is not sufficient space for another line of
writing. I make each indicator extend a little inward upon the tympan, with
sufficient space under it to receive the edge of the paper. These indicators move
upward with the paper. I provide a removable arm carried on what is generally
termed the envelope-holder, a brace which stands in front of the type-written
matter and holds the paper close to the cylinder. This arm aids the eye in
determining when, by the feeding upward of the paper, each indicator has reached
that level.
The device can serve by thus indicating to the eye alone, but I prefer to provide
also some means whereby a signal will be given to the ear, when each indicator
reaches the proper line.
The accompanying drawings form a part of this Specification and represent what
I consider the best means of carrying out the invention.
Figure 1 is a plan view of a portion, and
Fig. 2 a corresponding side elevation, certain portions being broken away.
Fig. 3 is on a smaller scale. It is a plan view of the tympan and its attached
indicators alone.
Fig. 4 is a plan view of one of the indicators partially manufactured. It is in
the extended condition which obtains prior to the folding.
Fig. 5 is a corresponding edge view.
Fig. 6 is a cross-section of a portion of a tympan with an edge view of an
indicator in its properly folded condition ready to serve.
Fig. 7 is an edge view of a portion of the tympan with an end view of the
indicator.
Similar letters of reference indicate corresponding parts in all the figures where
they appear.
A indicates portions of the fixed frame-work of the machine. B is the travelling
carriage, certain portions being represented when necessary by super-numerals
as B' etc. C is the cylinder, which serves as a. platen. It is supported in fixed
bearings carried on the carriage B. D is the feed-roller, E one of the ordinary
grooved pulleys, turning on the bar B', and F one of the slight rubber bands which
run between the roller D and the cylinder C, moving forward in contact with the

page_text: latter and ultimately around one of the pulleys E, and aiding to hold the paper
gently and steadily in contact with the under side of the cylinder. All these
parts, and such others as are not otherwise described, may be of the construction
and arrangement ordinarily adopted in what is known as the Remington type-
writer.
B2 is the ordinary envelope-holder or paper guide. G is a removable index
fitted thereon when my invention is to be used. It extends horizontally to the
left, and aids the eye in determining when the indicator has, by the feeding of the
paper upward for the several lines, come to the required level.
I provide a sheet of good paper, which I call the tympan, cut to the size of
the sheet which is to be type-written on.
propose to provide several of these
tympans of different sizes, adapted to serve respectively for large letter paper,
note paper, and other sizes which are likely to be required. For most offices
one sheet should be of a proper size for the legal-cap paper used. A description
of one tympan, which I will assume is adapted for note-paper, will suffice
for all.
H is the tympan sheet. II are indicators, of thin sheet brass, each formed with
a number of points i. By pressing these points through the paper and clenching
them, the indicators are firmly and permanently attached to the tympan. Each
indicator is folded as shown; one portion, that which is fastened, lies on the under
or back face of the tympan, and the other part I on the front, with a sufficient
space between it and the tympan to receive the edge of the paper M on which the
type-writing is to be produced. A strong black line H₁ is printed or otherwise
produced across the face of the tympan H opposite each indicator I.
K is a frame which is adapted to be secured on the carriage B, by means of the
screw J, and carries a small bell L. P is a lever carrying a sufficient hammer
head P¹ pivoted to the frame K at p, and having an arm P' which extends into the
path of the indicators I. This lever is subject to the force of a gentle spring Q.
It is adjusted with its head P¹ in the interior of the bell L, just out of contact
therewith.
In the use of the invention, the tympan H is removed from the machine and
the sheet of paper M is set in place with one edge under the folds I¹ of the
indicators. The paper thus accompanied by the tympan is inserted in the machine
in the ordinary manner, and the machine being operated in the usual manner, the
type-writing proceeds in all respects as usual. When, by the successive feeding
movements of the paper and tympan forward and upward, the sheet M has been
nearly filled with the printed impressions, and the first or uppermost of the two
indicators comes into line with the arm G, the operator knows that there is only
about sufficient space below for the ordinary formal terminating of the letter.
the eye may not be sufficiently observant to recognize the conditions, the ear
receives warning through the striking of the hammer P against the inner surface
of the bell L. The blow of the hammer is due to the action of the folded part I'
of the indicator against the arm P2 of the lever P. This action first turns the
lever against the force of the gentle spring Qand then liberates it. On the
liberation of the lever the spring Q brings it smartly back to a little beyond its
original position, causing its head to strike the bell.
As:
These parts are so adjusted that the hammer P will be lifted a little earlier, and
will be liberated so as to make the blow at the same time that the indicator arrives
in line with the cross-bar G.
In case the warning thus given is disregarded and the type-writing is continued
two or three lines farther, the second indicator comes into line with the arm G, and
the same operation is repeated, the warning being given as before, both through
the eye and the ear of the operator. This second warning tends to ensure
that the writing shall never be continued downward below or quite to the bottom of
the paper.
Modifications may be made without departing from the principle or sacrificing
the advantages of the invention. When carbon copies are required, two or more

page_text: sheets of thin paper M may be applied one over the other with carbon paper
between, in the ordinary manner. In some kinds of work it may be desired to have
a number of tympans H, each properly equipped with the paper ready to be
instantly supplied as each sheet is filled. For copying long documents on legal-cap,
only the lowermost of the two indicators should be used.
Parts of the invention may be used without the whole. The bell L, with its
supporting means K and its operating lever P and spring Q may be dispensed with
and the eye alone depended upon for receiving the warning. With paper which is
transparent the line H' may serve alone as a sufficient indicator. The arm G may
be permanently instead of removably attached.
The indicating devices may, obviously, be on the right instead of the left edge
of the paper, and the arm G may extend either to the right or left, or in both
directions.
I prefer the whole as shown.

I, FRANK WALDEN STANLEY of No. 310 Washington Avenue, in the City of
Brooklyn, King's County, in the State of New York, United States of America,
Clerk, 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 :-

only the lowermost of the two indicators should be used.

I prefer the whole as shown.
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 a type-writing machine, an indicator moving with the cylinder, arranged to
show on the exposed face and thus to give notice when the writing approaches the
bottom of the sheet, substantially as herein specified.
2. In a type-writing machine, an indicator adapted to be fed through the machine
with the paper, in combination with the arm G mounted on the carriage as shown,.
all arranged for joint operation substantially as herein specified.
3. In a type-writing machine, a flexible tympan carrying an indicator as the thin
metal fold standing in front of the paper M to be printed, in combination with
a device as the bell and hammer, arranged to be operated by the passage of the
indicator to give an alarm when the type-writing arrives near the bottom of the
sheet, as herein specified.
4. In a type-writing machine, a flexible tympan carrying two indicators each
having a part as the flap I' projecting, in combination with the bell L, and with
operating means P, Q, arranged to be actuated successively by the indicator 50 as
to give two warnings when the writing approaches the bottom of the paper, as.
herein specified.
