This invention relates to calculating devices
and more particularly to providing a machine
whereby perforated time cards can be rapidly and
accurately extended to determine the amount of
wages due the workman, for the elapsed time in
of the spring is held stationary to the shaft by
means of pin 3|, the outer end of the spring is
dicated by the perforations.
The device as set forth hereinafter can be
adapted to function with other forms of pre
pared cards for a variety of purposes.
connected to pin 23 on the inner side of the time
ring wall. Pin 24 which is also connected to the
inner wall of the time ring 2 comes to rest against
stationary pin 30 on the shaft 3, under the pres
sure of the spring 32. This pin 30 allows the time
ring 2 to make one revolution. Racks 4 in vertical
guides 40 and 4| normally mesh with gears 2|
t The main object of the invention is to enable 10 when held up by a spring ‘I2 to controlled bar ‘I,
an operator to obtain accurate and rapid equa
tions in hours and minutes and dollars and cents
representing the wages due on the working time
indicated by the holes pierced in the card, there
by reducing to a minimum the time required to
I prepare a correct statement of the wages due.
In the device shown and described provision is
made for a six day period. The device does not
print the amount, but exposes on a dial the daily
total, computed for the operator to take down
on an adding machine.
The device is shown in
the accompanying drawings in which.
Figure 1 is a perspective View of the device.
Figure 2 is a vertical cross section.
Figure 3 is a horizontal cross section.
Figure 4 is a side View of one of the time rings.
Figure 5 shows surface markings on the time
rings.
Figure 6 shows the dial slots in the rate drum,
exposing the ?gures.
Figure '7 shows details of one of the operating
handles.
Figure 8 shows a complete rate drum.
Figure 9 is an illustration of a time card perfo~
rated.
As seen in Figure 1, a base I I] has two side
pedestals I5 supporting the shaft 3. The ends
of the shaft 3 are squared to ?t into the slots I6
and are held by latches I'I.
Mounted to rotate on the shaft 3 are six time
rings 2, one for each day. The set of rings 2
are enclosed in a cylindrical light metal casing
I I forming a drum shaped housing Fig. 8, which
is secured to the shaft 3.
This drum I I is provided with six slots 42 on its
under side, that permit the racks 4 to travel
through the drum and engage with the gears 2 I.
There are also six apertures I2 as shown in Fig,
6, for reading the data on each time ring. Each
drum II represents a speci?c rate of wages per
hour and is readily interchangeable on the cal
culator. Each time ring 2 has a bushing 20 in
side and a gear 2| outside forming bearings.
The time rings 2 are connected to the shaft 3
which is journalled in bearings ‘ID. A lever ‘II at
one end of bar ‘I provides means for lowering the
bar ‘I and releasing the racks 4 from the gears 2 I.
The forward ends of the racks 4 are pivoted to
light metal rods 5 which terminate in operating
handles 6, having spring ball points 60. The rods
5 have guides 5I. The handles 6 are adapted to
travel in narrow slots I3 in the casing I, situated
directly above the columns with the holes 80
perforated in the time card 8.
The time card 8 is inserted through an opening
I4 in the end of the casing I and comes to rest
in the spring clips 8|. Its perforated columns
are then directly below slots I3, and this permits
25 the ball points 60 to press upon it and enter the
holes 80.
The handles 6 have springs 6| in tubes 62 bear
ing on projecting balls 60 which are adapted to
enter the perforations 80 in the time card 8.
Each rate drum Fig. 8 consists of six calculat
ing rings 2 each ring is printed on its outer sur—
face 25 as shown in Fig. 5, showing the elapsed
time and the equivalent dollars and cents repre
sented by the rate of that particular drum. Any
number of drums of various rates can be used
with each calculator.
The supporting bar ‘I which is operated by lever
‘II is kept in a raised position by a spring ‘I2.
When this lever is pressed down the racks 4 are
disengaged from the gears 2 I, this allows the
calculating rings 2 all to return to zero by means
of the spring 32.
The time card, illustrated in Figure 9 of the
drawings, is marked ed in ?fteen minute periods
from seven a. m. to six p. m. the noon hour from
twelve to one is omitted and all cards that punch
out at twelve o'clock and in again at one o'clock
are punched through the same hole-at both times,
and when the cards are so perforated and are ex
tended, it is only necessary to use the starting
and ?nishing hole in the card to get a complete
record for the day.
The method of operating the calculating ma
chine is as follows: All the cards of the same rate
by means of ?at spiral springs 32, the inner end 55 are stacked together and valued, when the ?rst
