Improvements in Pressure Recording Devices;
JOSEPH FRANKLIN BATCHELOR citizen of the United States residing at'
Number 138. Livingston Street in the City of Brooklyn, County of Kings and
State of New York, Mechanical and Electrical Engineer,, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in pressure recording devices, that is to
say, devices wherein a record is made as to the time and duration in which pressure
is exerted, and the same is adapted to be employed in connection with whistles
operated by pressure, as steam or in any other connection in which it is desirable
to record the time at which pressure may be present, in such relation as to affect
the device there employed and, the length or duration of time in which such pressure
is present.
I have illustrated my invention in the accompanying drawings in which like
letters refer to like parte.
Fig. 1. is a form of construction in which my invention may be applied wherein
the record' is made mechanically.
Fig. 2. is a form in which the record may be made by means controlled
electrically.

operation of the time mechanism C.
The operation of this device is as follows;

When pressure is interposed into the pipe A, aud chamber B, it affects the
cylinder head, and drives the point 6 against the disk c, to make a mark or
puncture therein, to indicate that pressure has been before the cylinder head. It
will be understood that this disk is preferably divided in the usual form, into days
or hours as the case may require. The disk as stated, is caused to revolve by the
time mechanism C, and as such revolutions: progress the record will be made upon
the same by the point &, either in the form of punctures or marks; according to
the length of time that the pressure is exerted in the chamber B, so will the longth
of the mark indicate the same.

The operation of this device is as follows:
When pressure is introduced into the pipe A, it affects the diaphragm F, and
causes the circuit maker f' to make electrical contact with the contact plates f
and, thus completing a circuit through the electro magnet G, thus attracting
the armature g¹ to operate the printing mechanism of the time stamp D, and
cause an impression to be made from the time stamp on the ribbon e, at the same
time actuating the deteut lever e, to release the feed roller e, thus causing the
paper to be continually-fed to the printing mechanism until the roller has made
a complete revolution and the pin e engages the detent levere when its motion is
arrested. It will be understood that when the diaphragm F is affected by the
pressure, the contact maker passes over the contact plates and completing-
a'circuit thereby, and with the further expansion of the diaphragm the circuit is
broken. It will also be understood that with the retraction of the diaphragm due
to the exhaustion of the pressure in the pipe A, that the circuit is again made as
the contact maker returns over the contact plates f and f, thus again causing the
electro magnets to print a record on the tape to indicate auch return.
It will be understood from this description, that with the expansion of the
diaphragm and the making of the circuit, a record is made of the time at which.
this occurs, and again as the diaphragm retracts a second record is made..
It will be manifest that if the impulses of the diaphragm are very rapid, that the.
distance between the impressions on the ribbon will indicate the length of time.
that the pressure is present before the diaphragm. That is to say, with the
expansion of the diaphragm the circuit is made, and the printing takes place, and
at the same time the detent is released and the tape is fed to the stamp, and with
the retraction of the diaphragm the circuit is made again, and the printing is:
repeated.
If the second making of the circuit occurs before the time stamp has had time to
complete its change of time indication, then the same time will be indicated twice,
but by reason of the feed of paper there will be a space between the impressions
from the stamp, the length of which space, will indicate the length of time the.
pressure is present before the diaphragin.
If on the other hand the pressure is exerted long enough to permit the time.
stamp to change, the imprint from the stamp will indicate the length of time the.
pressure is exerted against the diaphragm.

I, JOSEPH FRANKLIN BATCHELOR of 138 Livingston Street, Brooklyn, in the
County of Kings and State of New York, United States of America, Mechanical
and Electrical 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 pressure recording devices, that is to
say, devices wherein a record is made as to time and duration in which pressure is
exerted, and the same is adapted to be employed in connection with whistles
operated by pressure, as steam, or in any other connection in which it is desirable
to record the time at which pressure may be present, in such relation as to affect

page_text: the device there employed and the length or duration of time in which such pressure
is present.
The invention will be understood from the following description, reference being
had to the drawings accompanying the Provisional Specification, in which:
Figure 1 is a form of construction in which my invention may be applied,
wherein the record is made mechanically; and
Figure 2 is a form in which the record may be made by means controlled
electrically.
connected with a
In Figure 1, A is a pipe in which a chamber B is interposed having a port
cylinder 6 having one end closed and the other entering into
the chamber B; is a piston head and 6 a piston rod; b' is a point which may be
a puncturing or marking point secured to the end of the piston rod, and 65 is a
spring interposed between the head of the cylinder and the head 6. C is a time
mechanism operating a stem c', and is a disc secured to said stem c, and
revolving therewith, with the operation of the time mechanism C.
The operation of the device is as follows:-
When pressure is introduced into the pipe A, and chamber B, it affects thie
cylinder head b³, and drives the point 6 against the disc, to make a mark or
puncture therein to indicate that pressure has been before the cylinder head. It
will be understood that the disc is preferably divided in the usual form, into daýs
or hours as the case may require. The disc as stated is caused to revolve by the
time mechanism C, and as such revolutions progress the record will be made upon
the same by the point 6, either in the form of punctures or marks; according to
the length of time that the pressure is exerted in the chamber B, so will the length
of the mark indicate the same.
In Figure 2, A is a pipe, for instance say steam pipe leading to a steam whistle.
F is a diaphragm interposed in a port in said pipe is a circuit maker carried
by the diaphragm; and f' and fare contact plates in circuit connection with an
electro magnet G. D'is a time stamp of any of the usual forms, having a printing
hammer d', secured to an armature for said magnet g', E is a spool upon which is
wound a paper ribbon or tape e', which passes under the printing mechanism of the
time stamp, and between the rollers e and e³; e and e³ are rollers between which
said paper is intended to pass to feed the same to the printing device; e* is a
figurative representation of a motor, preferably a clock movement, suitably
connected to operate the roller e, in a direction to feed the paper to the printing
mechanism of the time stamp; is a pin secured to the roller ee is a detent
lever pivoted at e' to arrest the movement of the roller e³;
The operation of the device is as follows:-
.
When pressure is introduced into the pipe A, it affects the diaphragm F and
causes the circuit maker f¹ to make electrical contact with the contact plate f
and, thus completing a circuit through the electro maguet G, thus attracting
the armature g' to operate the printing mechanism of the time stamp D, and cause
an impression to be made from the time stamp on the ribbon el at the same time
actuating the detent levere to release the feed roller e, thus causing the paper to
be continuously fed to the printing mechanism until the roller e has made a
complete revolution and the pin e engages the detent lover when its motion is
arrested. It will be understood that when the diaphragm F is affected by the
pressure, the contact maker f¹ passes over the contact plates and f completing
a circuit thereby, and with the further expansion of the diaphragm the circuit is
broken. It will also be understood that with the retraction of the diaphragm due
to the exhaustion of the pressure in the pipe A, that the circuit is again made as
the contact maker returns over the contact plates aud f, thus again causing the
electro magnet to print a record on the tape to indicate such return.
It will be understood from this description, that with the expansion of the
-diaphragm and the making of the circuit a record is made of the time at which
this occurs, and again as the diaphragm retracts a second is made. It will be
"manifest that if the impulses of the diaphragm are very rapid that the distance

page_text: between the impressions on the ribbon will indicate the length of time that the
pressure is present before the diaphragm; that is to say with the expansion of the
diaphragm the circuit is made and the printing takes place,.and at the same time
the detent is released and the tape is fed to the stamp, and with the retraction of
the diaphragm the circuit is made again and the printing is repeated. If the
second making of the circuit occurs before the time stamp has had time to complete its
change of time indications, then the same time will be indicated twice, but by reason
of the feed of paper there will be a space between the impressions from the stamp,
the length of which space will indicate the length of time the pressure is present
before the diaphragm. If on the other hand, the pressure is exerted long enough
to permit the time stamp to change, the imprint from the stamp will indicate the
length of time the pressure is exerted against the diaphragm.
The drawing and specification of Figure 1 are intended by me to cover the
broad idea of making a record of the time of and duration of pressure when
exerted, the record being shown on a disc of paper revolved. by a time mechanism.
In the drawing of Figure 1 is shown a point which may be a puncturing or
marking point secured to the end of the piston rod. and I do not desiro to copfine
myself to one method of producing the indication on the paper, as it is evident that
I may effect it in several ways, for instance:
I. I may attach the puncturing needle to the piston end by a joint, allowing the
needle point to swing toward one side, a weak flat spring hearing on that side of
the needle, the spring being attached to the piston rod. The operation is that
when the needle point is driven into the paper by the piston, the paper instead of
holding the paper back continues to move, but the sideways movement of the
"needle point allowed by the flat spring permits it to draw out of the puncture and
make a scratch or indentation on the paper as long as pressure is exerted.
11. I may use a point which is a marking point, eay a point of silver wire and
chemically prepared paper discs. In this plan, the silver point would be attached
to a holder sliding within the hollowed piston rod 68 and a spiral spring exerting
its tension against a stop on the piston rod and against another stop on the holder
would keep the silver point pressed against the chemical paper whenever pressure
is exerted. I may use an ordinary lead pencil or iuk stylus to make the mark as
.above.
III. Instead of a point, I may place a loose toothed marking wheel on the end
of the holder described in II, in which the teeth of the wheel would puncture the
paper, indicating time for each puncture made by the revolution of the teeth
coincident with the revolution of the paper disc.
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 pressure recording device, a piston or diaphragm operated by pressure,
and a puncturing or marking point operated by the said piston or diaphragm, in
combination with a time mechanism and a disc or its equivalent caused to revolve
by the time mechanism aforesaid, said disc or its equivalent being so placed
relatively to the marking or puncturing point, that when pressure is interposed
against the piston or diaphragm, the point is driven against the disc to make a
mark or puncture thereon, substantially as and for the purpose described.
2. In a pressure recording device, a piston or diaphragm operated by pressure,
in combination with a time stamp, an electro magnet in circuit, an armature for
said magnet connected to operate the printing mechanism of the stamp and also a
detent controlling the feed of paper to the stamp, and means to control said circuit
operated by the movement of the diaphragm, first by its expansion and second by
its retraction, substantially as described.
3. In a pressure recording device, a piston or diaphragm operated by pressure
in combination with a time stamp, an electro magnet in circuit, and means to
☐ control said circuit, consisting of a contact maker carried by the diaphragm,

page_text: engaging contact plates as the diaphragm expands, and again as the diaphragm
retracts, an armature for said magnet connected to operate the printing mechanism
of the stamp, and also a detent controlling the feed of the paper to the stamp,
substantially as described.
4. In a pressure recording device the combination with a chamber adapted to
receive pressure, a piston or diaphragm exposed to said pressure, and connected
with a circuit controller, controlling an electric circuit through an electro magnet
first by the expansion of the diaphragm to make and break the circuit, and second
by the contraction of the diaphragm to make and break the circuit, said magnet
having an armature connected to operate the printing mechanism of a time stamp,
and a detent controlling a motor to feed the paper to the printing mechanism,
substantially as described.
