Calculagraph
© Brooke Clarke 2008
Model 110 Model 33
Background
Prior to the Calculagraph when
the
elapsed time was needed, like for phone calls or workers time
cards, a
manual procedure was followed. The starting time was
hand printed
on a card and then the ending time was hand printed. A
clerk
would subtract to find the elapsed time. About 20% of
the time
the clerk made a math error. The Calculagraph prints the
start
time and the elapsed time so no calculations are needed.
Note no
math is done in the Calculagraph it just prints the elapsed
time dials
at the start and the elapsed time pointers at the end.
They were
used all over the world.
Calculagraph patent 583320 issued May 25, 1897 by Henry Abbott. This was one of the first time printers. An early use was in pool halls where a ticket would be printed using the start lever and when the table was no longer being used by the stop lever. Inspection would show the elapsed time (or optionally the dollar amount would be printed). This may have been the origin of the expression "Time is Money". The round style unit shown above is based on this patent. The plating at the front of the model 110 has been worn away indicating that this unit has seen a lot of use. It would be nice to know where that happened.
A later application was for timing phone calls where the Model 33 shown at the right above was used in a similar manner. That's to say the operator would insert a card and stamp the time when the call started then stamp it again when the call ended. Note that the Model 33 is only connected to a power source, not the phone lines so the accuracy of the timing depended on the operator. By 1904 Henry has patents for telephone call timers that are coupled to the phone lines, but the Model 33 was patented in 1941 and was widely used. So maybe the 1904 type call timers were not actually used.
The Model 30 looks very much like the model 110. It has a 5 3/4 " diameter clock face, the handles are about 1" in diameter. and the can that covers the bottom is about 9" in diameter that goes into the switchboard position shelf. The IBM mark sense cards were the same size as the standard punched card 7 1/2" X 3 1/4" as I measured them crudely.
Google Image search has many photos of these as well as the other products with the same name.

The Calculagraph and its
Functions.
The manufacturers who devised the calculagraph have made a great advance on all other systems of time recording. The ingenious calculagraph saves 50 per cent or more of the time clerk's work by registering the time at which the job commenced, and mechanically subtracting this from the time of finishing; the difference or time elapsed is then printed in hours and minutes on the card dropped into the slot.
The calculagraph makes no clerical errors, and can be manipulated by anyone. It is only necessary to push a card into the slot and pull a lever, and the number of calculations this clever machine can make is only limited by the number of cards it is possible to push consecutively into the slot during a given time.
. . . .
Special calculagraphs can also be had for industries or factories where the rate of pay per hour is uniform in the department, which print the value of the elapsed time in (pounds Sterling), s. d. or other coinage. The calculagraph therefore, obviates all necessity for clerical work on the part of the workman, besides saving half that of the time clerk. . . . .

Brooke,
Attached is the article from the Jan. 1928 issue of Electrical Communications. This was published by IT&T in New York.
Before the Calculagraph, the operators noted the start time and stop time from a clock on the wall on a paper ticket and then subtracted the former from the latter to determine the minutes and seconds elapsed for calculating the charge on the call. Normally there was a basic rate for the first 3 minutes and a per-minute overtime rate for each additional minute, or fraction thereof. The extra-minute rate was usually about 1/3 of the basic 3-minute minimum rate.
Because there were many calls at progress at any one time, and because a single Calculagraph normally served two complete switchboard positions, there was no way to associate a specific call in progress with the Calculagraph. That would have required a Calculagraph for each connecting cord circuit. There were normally at least 10 cord circuits for each operator on every switchboard position, which meant that there could be 20 calls requiring timing in progress when all 10 cord circuits on the two positions were connected. Stamping each toll ticket when the call started, and again when it was completed, allowed a single Calculagraph to do the time recording for many calls. While the call was in progress, the toll ticket was stored temporarily in a slot in the keyshelf associated with the particular cord pair over which the call was being completed. That way the operator knew quickly which toll ticket to slip into the Calculagraph and pull the handle when the call was completed. Accuracy was dependent on the operator being very prompt in stamping the toll tickets when conversation began and when it terminated. It was only as accurate as the operator was fast.
Also, on magneto switchboards, there was no sure electrical signal when the called party answered or when the parties hung up. Subscribers were supposed to "ring off" when they completed a call to tell the operator the call was over, but they often forgot to do that. The operator had to constantly be monitoring the calls to determine when each call was completed and then
quickly stick the toll ticket into the Calculagraph to stamp completion. She would open her listening key just long enough to make sure the parties were still talking. If she heard no conversation, she would ask "Are you through?" If there was no response, she knew the call was done and proceed to stamp the toll ticket in the Calculagraph. It was a very "manual"
process.
I have seen L M Ericsson toll switchboards, made in Sweden, for common battery and automatic dial toll service where, instead of a Calculagraph there was actually a meter mounted in the switchboard keyself, one for each cord pair, which was electrically operated to start counting elapsed time when the answer lamp went out (when the called party answered) and stopped counting when either party hung up. This was electrically operated. The operator then read the elapsed time from the meter and noted it on the toll ticket. This elapsed time was used to manually calculate the charge for the call. This was a more accurate method, but required a much greater investment than did the Calculagraph.
It wasn't until TSPS cordless toll switchboards came along that timing actuated by the subscriber's hanging up was employed to determine elapsed time on long distance calls. This is when call billing data started being recorded on punched paper tape rather than on individual paper toll tickets.

A "Calculagraph" is an
instrument for
automatically recording lapsed time and is used specifically
in
recording the length of time a long distance telephone has
been used by
the operation of a lever at the beginning and end of such
use, and also
the time of day when such use was
commenced. Calculagraph Co. v.
Wilson, 132 Fed. 20, 22.
Henry Abbott
Henry worked as a watch smith in
New
York. At that time the import duty on watch parts was
lower than
on complete watches, so he imported the parts and assembled
watches. Prior to inventing the Calculagraph he invented
a way to
convert a watch from needing a key to wind to to using the
stem for
both winding and setting the hands. With his invention
key wind
watch movements could be converted to stem wind making them
more
desirable (valuable).
Description
Round Model 110 Calculagraph
The key idea is that when the start lever is pressed back it prints the graphical clock showing the start time and when pulled forward it prints the two outer circles that will show the elapsed time (not the stop time). When the card is again inserted and the stop lever is moved back and forward it prints the arrows in the elapsed time circles. Note that the arrow always points to the zero position of the circle, but they are printed at different times so show the elapsed time.There are two holes in face as shown in the photo at the top of the page. In the left "day of month" hole is a square post that can be turned with a common clock winding key (3.4 mm size). That same key can be used to press the cylinder under the right hole to advance the months. The Time Savers (#10050) 3.4 mm key fits the square pin, but it too short to work the month advance so a key that's longer would be a better choice. Also the squard pin does not want to turn. Not sure why.
It's not yet clear how the hours and minutes are set.
This is a later version of the original round model. The 583320 patent shows a unit that's powered by a clockwork spring, not an 110 VAC electric motor like this model 110.
1582651 is the 1926 patent for auto reversing the ribbon and this model 110 s/n 52756 has auto reverse on the ribbon.

The cord goes through a
gromet
in the side of the can so the socket on the cord must be assembled after installing the cord. It mates to a plug visible in the photo below. |

The
large type
wheel has the days of the month. The wheel to the right has the months of the year. |

There are five print
wheels in
this photo. The three clock face type are left to right: * left Start Time is a three part dial the outer dial (I to XII) is fixed (XII always at top), the minutes arrow turns with the visible clock face minute hand, The triangular hour pointer turns with the visible clock face hour hand. Pressing the START (left) lever back causes both the outer dial and arrow to print. * center TENTHS dial is two parts. Pressing START (right) lever forward causes outer dial to print (not pointer) Pressing FINISH (left) lever forward causes TENTHS pointer to print. * right HOURS dial is two parts. Pressing START (right) lever forward causes outer dial to print (not pointer). Pressing FINISH (left) lever forward causes HOURS pointer to print. * center below tenths is the DAY OF MONTH wheel with numbers on it's edge. Pressing START (right) lever forward causes wheel to print day of month. * right below hours is the Month wheel with numbers on it's edge. Pressing START (right) lever forward causes wheel to print three letter month. |

The hands are set just
past
12:00 to allow the pin to clear the Day Of Month set
arm. When the arm is riding on the pin there is not enough are swing to cause a date change. This prevents getting the time and date out of sync. |
Setting Time & Date
On the visible clock face there are two ways to mount the minute hand to it's shaft and only one of them is correct. The hour hand is a friction fit and needs to be rotated to match the start time small triangular pointer. The minute hand should be installed to match the minute pointer in the start time dial.To set the time turn the visible minute hand clockwise (not counterclockwise) until both the hour and minute hands are showing the correct time.
There is a pin on the hour gear that restricts the movement of the day of month setting key and a little after 12:10 the pin allows full movement of the day of month key so for each CW-CCW cycle of the key the day of month advances one day. Note that the day of month and the month need to be set manually since they are not connected to the clock work.
Key
Jeffrey Lamb of Kingston, Ontario makes a new setting key.
Rectangular Model 33 Calculagraph
The model 33 was made expressly for use on telephone switchboards. It's powered by a 20 VAC electric motor. The narrow rectangular shape allows it to fit on the table part of a switch board and not take up anywhere as much space as the round model would. |

Note that the Model 33 does not have day and date wheels like the Model 110. Less to maintain.
This is the plate that's just above the printing wheels.
On it's
back side is an almost hard rubber strip that has a give to
allow the
type wheels to depress the time card. The Model 110 also
has the
same rubber strip under it's top plate.The clock Hour, Minute and Second hands just press on the shaft on the right side gear. No nut is needed like on the Model 110. If this plate is turned upside down the gears will fall out.

Inking
By manually operating the FINISH
lever
the ribbon will feed. When the end of travel is reached
the
direction is supposed to reverse. But on both of these a
very
small drop of oil on the reversing mechanism was needed to get
them to
auto reverse.
By applying stamp pad ink just prior to the take up spool you can see the ink from the ribbon that's already on the spool soak through to the new ribbon that's being wound on. If you don't see the ink wetting the new ribbon then add more stamp pad ink.
Note that working any of the levers to advance the ink also puts ink on the rubber platten and that needs to be cleaned before using the Calculagraph.
