15 Claims. (Cl. 177-351)
This invention relates, in general, to an appa
ratus having means for automatically ascertain- -
ing the changes in a registering device, such as
a thermometer or the like, and for signaling the
,5 resultant ?ndings over a conductor or by radio
Another object of the invention is the provision
of an apparatus to alternately detect such ?nd
ing in a group of registering devices and while so
10 detecting the condition of each device to auto
matically record such conditions on a tape as‘a
permanent record thereof or for the purpose of

Fig. 13 is a circuit diagram for the same.
Referring now in detail to the drawings:
The numeral 1 designates the bed plate sup
porting the standards 2, in which shaft 3 is loosely
journaled. Securely fastened on the shaft is gear 10

' Still another object of the invention is the pro
vision of an-apparatus which will be especially
applicable for isolated spots for reporting meteor
ological and other ‘conditions. As a speci?c ex
ample I have shown a thermometer and a barom
20 eter but it is to be understood that these are
merely examples and not a limitation of types of
instruments which may be used.
The many novel features embraced in this in
vention are far-reaching in their scope and are
25 applicable in many embodiments other than that
which will be described, and I therefore do not
wish to be limited except as indicated by the

of which has ratchet teeth I'I, ‘engaged by the
spring pressed pawl 18, for the purpose-of retain
ing the bar in its attained height when the power 1
is released.
* The two sides [9 of the bar are recessed to slid
ably fit into the guide l5, which is securely at
appended claims.

held against lateral movement on shaft '3 by suit- v
able means 35, Fig. 3, and the hub 86 of the pin
ion 58.
The rod 89 is slidably mounted'in bearing 38

Fig. 10'is a top view of the thermometer and
has two ‘projecting arms 43 and 44. The arms
have slots 45 and 46, of such length, as to pro
vide freedom of motion for the rods 39 and 41,
when pivotally tied by bolts 48 and 49.
The forked head 59 of rod 41 is pivoted to the
rod 5|, carrying the contact roller 52, and rock-;
ably mounted in bearing 53. The spring 94 nor
mally holds the roller from contacting with the
code wheel as the roller 49 rests on the ?attened
portion of the cam 94 when the latter is in normal
position. The forward throw of the contact roll
10 er across the face of the code wheel ‘I, which is
stationary at this time is brought about when
the cam presents its non-?attened face to the
roller 49, at which time the spring is under ten
sion so that it will return contact roller 52 to its
15 non-contacting position upon the return of cam
84 to its normal position.
The cam 93, controls the release of the pawl I8
from the rack bar, through the angle rod 55,
Journaled in bearing 56, and having a projection
20 51 cooperating with said part. At the instant of
release, the bar, through its own weight, falls
downward to normal position. As the movement
of the rack bar and code wheel are coincident,
both members'return to normal at the same time.
25 This release occurs at the instant when the key
has reached its farthest travel beyond the code
wheel to the left, when the code wheel will swing
forked lever means operated by an electromagnet
I51 and spring I59 (see Fig. 5) which operation
will be later described. The electromagnet I51,
forkediever I58 and spring I59, schematically
shown in Fig. 5, are located below the cylinder 99
when the device is viewed in plan and therefore
are not shown in Fig. 1.
A sprocket wheel 93 having a hub 94 is loosely
mounted on shaft 99 between the gear 89 and
clutch member 91 and held laterally by suitable 10
means such as a set screw or pin not shown. The
hub 94 is provided with holes 95 for cooperation
with the pins 96 on clutch member 91 when said
clutch member is in its left hand position as
viewed in Fig. 1. A drum 99 is also loosely mount 15
ed_on shaft 99 between the clutch member 91
and bearing I94. The end I93 of drum 99 is pro
vided with holes to cooperate with pins on clutch
member 91 in a similar manner to the cooperation
of holes 95 and pins 96. Drum 99 is proyided with 20
a series of pins I99 for cooperation with perfora
tions I9I along the edges of paper tape I92. The
member 99 is suitably restrained from axial
movement along shaft 99.
A shaft I95 mounted on base I parallel to shaft
99 by bearings I99’ and I99" carries a drum I95
similar to drum 99 and having pins I9‘I like pins
I99. This drum is fixed to shaft I99 by suitable
freely around, and come to rest as the contact
roller commences to traverse backwardly over
30 the portion of the face of the code wheel not
means and is driven by means of sprocket wheel
I I9 mounted on the end of shaft I99. A chain
I I I connects the sprocket wheels 93 and H9.
Reference is made to Fig. 11 as well as Fig. 1
provided with code forming projections.
The hub 92 of the cams 33 and 84, extends to
the right of the cams and supports the pinion 58.
Meshing therewith is gear 59, carrying the drum
35 switch 99, in which metallic plates GI and 62‘ and
2“ are embedded-the whole being supported
on shaft 93, supported as by hearing 94.
Electrically contacting with the metallic plates
9|, 92, and 2“, are the brushes 65, 96 and 2I9,
40 which are held fast on their insulation support 61.
Projecting outwardly from the bearing 64 and
?xed on shaft 98 is the pinion ‘I9 which meshes
with the large gear ‘II provided on the end of the
drum switch ‘I2, carrying the metallic plates ‘I3,

a stop means for the roller key 52.
In addition to the means already described the
55 apparatus mounted on base I includes a recorder
of the type in which a tape is perforated at in
tervals and additional contacting means for co
operation therewith to control a delayed trans
mission of the instrument readings. This means
is connected to the main driven shaft 3 by means
of an irreversibledrive so that it is driven in one
direction only. ‘A more detailed description of
this means is now given.
Shaft 99 is mounted in spaced bearings 92 and
65 I94 which are ?xed to the base I, a gear 95 is
loosely mounted on said shaft and engages with
pinion I9 to be driven thereby. A ratchet wheel
88 has its hub pinned to shaft 99 by pin 9|. A
pawl 91 is mounted on the side of gear 99 and is
70 pressed into engagement with the teeth of ratchet
wheel 98 by spring 89. Thus the shaft 99 is driven
only when pinion I9 is driving the rack I6 up
A clutch member 91 is‘splined to shaft 99 by
75 spline 98. This member 91 is shifted by the usual
Any ordinary "step by step” movement, not
shown, may be employed to move the paper along
for other stampings.
The non-magnetic bars I22 and I23 aligned
with guide rods I24, and the iron plungers I25,
freely journaled, constitute the stamping die.
The electromagnet I28 with an extended core I2'I,
serves to attract the iron plungers when ener
gized. Such successive energization of the mag~ 60
net as might be caused by any kind of rotary
switch, affords means for the plungers to faith
fully reproduce successively any one of the letters
or numbers carried on the face of the code wheel,
when presented.
The bottom portion I23, forming the movable
head of the die has the dependent rod I29 jour
naled in bearing I29, and armature I39, in this
way, the solenoid I3I, when energized, forces the
head, beneath the paper, upwardly to engage the
plungers, when the perforation of the paper is

paratus, omitting the perforator and the electro
magnets operating the same. The relay magnets 75
I32 are shown beneath the base, with armatures

the system will be later described. The projecting
end carries electrical contact I35 oppositely op
posed to'electrical contact I36 insulated from the
base by insulation I31 and kept open when the
rack bar i6 seats upon the armature or when
magnets I32 are energized and closed during the
upward movement of the bar by the spring I38,
10 provided said magnet I32 is deenergized.
The means for‘ electromagnetically operating
the clutch member I3, is also shown wherein the

which is also pivoted as at base I45. The upper
end of the rod is of the usual design for engaging
a slidable clutch; forked ends with adjustable
er 24, and turns the code wheel 1 around corre
20 screws.
Fig. 5 is a circuit arrangement showing how
one or more recording devices, such as the ther
mometer “a” and barometer “b” may be mon
itored and the readings broadcasted. The clock
25 switch I46, and the circuit controlling the motor
6, is represented by the conductors I41, I48. and
source I49. The rotatable metallic portion 80
of the switch 12 shunts the clock switch through
conductors I50 and I5I. The insulation insert BI
30 on the rotatable metallic portion of the switch
12 serves to break the motor current after the
shaft 62. or switch has made one cycle. after.
which time the motor must again be energized by
the clock switch or by some similar method.
Describing the operation of the apparatus and‘
referring to Figs. 1 and 5, the clock switch I46
may close at predetermined periods and when so
closed the motor 6, which ‘serves to drive the
shaft 3, and incidentally shafts 63 and 82, be
40 comes energized. In order to short-circuit the
clock switch I46 and to- establish a predetermined
time limit to the operation a switching means
comprising a metallic portion 80 of switch 12
with an insulation insert 8| and brushes 80 is
connected across said switch I46 in the following
manner: lead I5I connects one brush 80 to nega
tive of battery I49 and lead I50 connects lead I41
to the other brush 80. When the system is In
normal condition insulation 8| is under brushes
50 80 maintaining an open circuit at this point.
The main clutch I3, having taken hold the pin
ion I0, uplifts the rack bar I6 supporting the roll
spondingly to a degree with respect to the align
ment of the contact roller 52 across its face until 20
the roller 24 rises above the level line between
the point of contact and the top of the mercury
column I63 where it loses the current and causes _
the electromagnet I60 to become deenergized, al
lowing the spring .I10 to again contact with the 25
lead "I, leading to the electromagnet I I4,'which,
on becoming energized, for the second time perfo
rates the paper strip, this time, indicating the
height of travel of the bar. The circuit of the
punching unit may be traced through the spring 30
I10 on the armature of the electromagnet I60,
thence through the.conductor I1I, electromag
net II 4, conductor I12, brushes 16, conductors
I14 and I48, to the positive side of the source I49.
From the negative side of the source, conductors 35
IN and I68, conductor I69 and thence back to
the spring I10, as shown.
In this manner the distance between perfo
ration in the paper strip is made to represent the
distance traveled by the rack bar and code wheel. 40
Therefore, each successive action of the appa
ratus is recorded permanently, and, later, through
other movements, may be made to automatically
repeat such action.
As each action causes an .
additional step forward of the paper strip, the 45
strip eventually forms into a loop I08, Fig. 11.
Upon the ‘main clutch circuitbeing broken the
spring I40 engages clutch I3 with hub 32 and the
switch drums 60 and 1.2 and cams 36 and 34 are
again made to rotate by power from shaft 3. The 50

such action has already been described which
brings us to the point where the whole may be
again broadcasted collectively through the re
15 corder during the second phase of the cycle of
the drum 00 when the monitoring is silent the
plates not being shown. In this case the cam
05 is omitted from the apparatus. The length of
time of the monitoring and broadcasting is de
20 termined by the clock switches I40 and IE3, which
may be made to shunt the insulation 0|, on me
tallic drum 12, otherwise as shown, the action
of the whole will stop as the brushes 00" contact
with the insulation insert 8i, thus completing
25 period of broadcast, which may be renewed by the
clock switching means at certain periods. Where
the instruments are monitored only for one-half
phase of the drum 00 and the cam 05 having
its eccentric extension arranged to interrupt the
30 path of the roller 52 may be timed to stay the
roller 52 to the left side, during this time, until
the beginning of the second half-phase of the
cycle when the cam may release the roller and
the clock switch I53 may close to energize .the
auxiliary circuit controlling the electromagnet
I51 of the recorder.
The circuit for the same
consists of the clock switch I53, conductor I 55,
electromagnet I51, conductor I54 to the nega
tive side of the source I50, and from the posi
40 tive side of the source to the pivoted end of the
switch I53. With the disengagement of the
clutch 01 of the recorder from the sprocket wheel
03, the drum 08 turns in engagement with the
clutch 01 and advances the paper strip I02 up
from the loop I00; beneath the contact roller I I2,
and thereafter, electrically contacts with the
of the brushes 10 which contacts the plate 15.
It will be noted that the armature is held
downward by the weight of the rack bar which
is provided with the insulation 3i in its normal
position against the bias of armature spring I30.
When the rack bar is raised contacts I30, I31 and 15
lead I8I are allowed to complete the circuit of
clutch operating magnet I00. Thus while the
paper strip separates drum 09 and contact roller
H2, the clutch magnet I00 remains energized in
a manner similar to when energized through the 20
mercury column in monitoring the upward travel
of the roller 24, when the paper strip moves for
ward and presents another perforation beneath
the roller II2, the electromagnet I32 is energized
and draws the armature downward to break the 25
circuit through‘the electromagnet I60 for an
other length between the perforations in the
paper strip, and so on, until the last perforation
arrives at a predetermined position, when the
clock switches I53 and I 40 will open simultane 30
Fig. 8 shows the clock switch I53, together with
the motor circuits and transmitting set condi
tions, as similarly shown in Fig. 5.
The drums, 80 and 12, may have many plates
according to the gear ratio, in this respect, how
ever, I have shown but four ‘metallic plates, 0i
and 02, surrounding the one-half phase of the
drum: the other side of the drum is left blank
except for the smaller plates 2I4 which are 40
equally spaced around the drum. The plates 13,
14, and 15, on drum 12 are suitably arranged to
cooperate with the plates SI, 02 and 2“ of
drum 00, and the clock switches I40 and I53.
The cam 05 is for the purpose of making captive 45
the contact roller 52, and may come on at any
drum 00 as the holes are encountered to complete prearranged time of the system, as for instance,
the circuit through the system. The position of ' when it is desired to monitor and record the data

cuit through'the electromagnets I32 and IE0.
Tracing the circuit for the electromagnet I32,
whichv is operably associated with the perfora
tions in the paper strip, there is shown plate 14,
65 one brush '11, conductor I10, roller II2, under
which the paper strip is drawn, the drum 00,
electromagnet I32, conductors I10 to conductors
I00, IN to the negative side of the source I40,
from the positive side of the source through con
ductor I 40, thence over conductor I14 which has
a short lead to the other brush 11 and to plate
14. This circuit, through the electromagnet I32,
is controlled by the paper strip I02, and performs
the same service with respect to the operation of
the clutch magnet I00 as the column‘of mer
cording with each action of the apparatus, or may 80
be omitted, as the case might be.
Fig. 7 showshow a multiple roller 24 and 25,
electrically connected to each other and to the
rack bar support I0, may engage a multiple row
of metallic buttons 2“ and 2i I’ on an insulation 05
panel 30 and electrically connected separately
with the plates 0| and 02, as might be inserted
in the circuit, Fig. 5. Any number of rollers, on
one rack bar, and as many rows of buttons, prop
erly insulated on a panel, may identify a num
ber of instruments successively as the plates GI,
02 et seq. are successively contacted by their re
spective brushes.
In Fig. 8 the main clutch circuit for energiz~
ing the electromagnet 00 is slightly modi?ed to
conform ‘to the application of a photocell, which
functions in lieu of the roller 24. The cell I94 is
energized and attracts the armature I99, there
housed in the case I93, on top of the rackbar in
net I60, in the same manner as shown in Fig. 8.
The circuit of the relay may be traced from
alignment with the lamp I9I, also housed oppo
sitely in the case.
The whole forms a part of the movement of
the rackbar. As the rackbar rises the light rays
scan one side of the thermometer, the mercury
of which forms a shutter for the cell opposite.
10 0n reaching the top of the mercury,'the light
rays pass through the stem uninterruptedly to
the cell, which on being sensitized through the
leads I96 and/I91, instantly energizes the relay
I96 through—leads I96 and I91, whose armature
15 I99 becomes attracted, and, similarly, as the roll
er 24 rises above the mercury, the relay breaks
the current through the electromagnet I60. The
circuit may be traced as follows: the two con
ductors I64 and I66, leading from source I49, in
20 cluding contacts 65 and the plate 6|. ‘From the
negative side of the source I49 the conductors
I6I and I68 connect with electromagnet I60
and from the magnet through conductor‘ I62,
pawl I8, rackbar I6, and therefrom through lead
20I back to the armature I99. With the excep
tion of omitting plates 2I4, the switch 60 is of
the same construction and has the same parts
as shown in Fig. 5. The circuit for the elec
tromagnet II4 for recording the perforations in
80 the paper strip is also the same as used in Fig. 5.
The circuit used in broadcasting the data, how
ever, on account of the relay application, is dif
ferent to the extent that electromagnet I32 is
omitted, the member I82 taking the place of
armature I33, the contacts, etc., being the same‘
as in Fig. 5. From the member I82, when free,
the circuit continues through conductor 200 to
relay I98, and thence through conductor 200'
to roller I I2, and through the perforation in the
40 paper to drum 99, thence through conductor I19
, through brushes 11, to plate 14, across the plate
14 to the short lead connecting the conductor
I 14, and through I48 to the positive side of source
I49. From negative side of source through .con
ductors I6I, I68, to conductor I16, back to arma
ture I82.
The lamp circuit, which is also controlled by
the plate 13, is composed of conductors I6I and
I95, leading from negative side of source I49 to
lamp I9I, conductor I94 to conductor I12,
brushes 16, plate 13, and conductors I14, I48 to
the positive side of source I49. The clock switch
I53, and the electromagnet I51, operate in the
same way, as in Fig. 5.

and 13, wherein the swinging pointer type meter
The gear I0 is shown in mesh with the teeth
of the curved portion of-the rackbar I6a which
is shaped to swing around freely on a shaft, as at
point 209, centrally but independently of the
shaft of the meter. The top of the bar is pro
vided with the resilient blade 2I0, with its top
most portion bent inwardly so as when the pin
ion I0 turns the rackbar backward the bent por
tion of the blade will swing forward and elec
-70 trically engage the pointer 201. As the move
ment of the blade is synchronized with the move

position corresponding to that of the meter

I98, conductors I95, I6I, to negative side of the
source and from the positive side of the source
I66 to conductor I48, thence to conductor I14,
across plate 13, to conductor I12, thence to
conductor I94, and then to pointer 201.
The main clutchcircuit, operating the elec
tromagnet I60 is followed from the armature
I99, through conductor I64, across plate 6I
through conductor I66 to the positive side of_
source I49, and from the negative side of the 15
source to conductors I6I, I68, electromagnet I60,
thence through conductor I62 to pawl I8, pinion
I0, to conductor 20I and back to the armature
The broadcasting circuit may be traced from 20
plate 14 through brushes 11_ to conductor I14,
thence to conductor I48 to positive side of the
source I49 and from the negative side of the
source to conductors I6I and I95, to relay I98,
thence through conductor 200 to member I82, 25
conductor 200' to roller II2, drum 99, conductor
I19 and through other brush 11 to plate 14.
Fig. 2 shows a modi?ed form of the code
wheel 1, which is constructed of non-magnetic
material and has an open side to permit the por 80
tion I21 of the core of electromagnet I26 to ex
tend inwardly and over the projections 8. Prop
erly spaced beneath the projections are the iron
plungers I25 which are loosely supported in the
non-magnetic bar I22, held fast to the table top
by pins I24. The head I23, attached to the ar
mature I30, forming a part of the non-magnetic
rod I28, has a series of holes in alignment with
the iron plungers I25. The plungers normally
escape the projections 8, but when the magnet 40
I26 is energized are drawn towards the pro
jections ‘and spaces between them as shown.
Such plungers as are free to become magnetically
attracted rise up into the spaces between the
projections and when so attracted, do not reg 4-5
ister when the head I23 is forced upward to
take the impression of the plungers as they
might array beneath the projections of the code
wheel. The paper has a step-by-step motion at
right angles to the code wheel, in order to take
other impressions of the code wheel. Any suit

be divided into two integral parts, and how the ,
hoto-cell may be kept in alignment with the
lamp case by the looped arm 202, attachedto the
photocell case ?xed to the head of the rackbar
I6. The loop is for the purpose of allowing the
thermometer to be displaced by another instru
ment of similar design when such instruments
are mounted on a carriage and passed on succes
‘sively from the loop after having been monitored.
The thermometer is shown coated with black
enamel 203 with two slits along its length 204 and
205 to permitthe light rays to pass to the photo
cell. A top view of the thermometer and cases
is shown in Fig. 10.
