2 Claims. (Cl. 235-91)
The invention is a simple and inexpensive
counting device by which a t-ally may be kept.
It is particularly useful to farmers, truck drivers
and pieceworkers, and will be found to‘be gen
erally useful in many other ?elds of industry in

is desired to secure the back plate by more than
which it is desired to keep a tally or score.
The device is equipped with a pull chain manu

to fastening elements. The use of these additional
A counting
mechanism is contained within a casing and is
actuated by a tripping mechanism when the chain
is pulled.
A salient feature of construction resides in pro
viding a lug for suspending the casing on a wall,
and disposing the pull chain so that the pull is
taken directly on the lug without any tendency to
cause the casing to wabble.
The invention essentially consists of a counting
mechanism in which a step by‘step rotation is
imparted to an actuating ratchet wheel by a trip
20 dogcarried by a ‘quadrant operated by the pull
chain. The invention also comprehends a reset
ting mechanism comprising perforated dials
manually turnable by a pick that for convenience
is carried by the pull chain.
Having brie?y recounted the nature of the in
vention, reference is made to the accompanying
drawing in which Figure 1 is a perspective view
in which a part of the front wall is broken away
to disclose a unit dial.
Figure 2 is a view of the back of the case.
Figure 3 is a vertical cross section taken on line
3—3 of Figure 2.
Figure 4 is a vertical section through the full
width of the casing and showing the mechanism
therein, the tripping mechanism being depicted in
retracted or normal position.
Figure 5 is a similar but fragmentary view
showing the tripping mechanism advanced by the
pull chain.
Like numerals of reference indicate correspond
ing parts in each figure throughout the drawing.
Referring to the accompanying drawing in
which the preferred construction of the invention
is illustrated, the numeral 6 generally denotes a
45 casing having a front wall 1, integral side walls 8
and a detachable back plate 9. The front wall
contains three horizontal aligned apertures IE]
constituting sights. The back plate enables
access to be had to the interior of the casing and
50 is preferably detachably connected by prongs H
inserted in apertures.
The ends of the prongs
may be bent over‘ to form a secure connection. It
will of course be understood that other means
may be resorted to for the purpose of attaching
55 the back plate, if so desired.
The top of the back plate has an integral lug i2
upwardly extending and pierced as at $3 receptive
apertures, however, is optional.
Formed in the back plate is a suitable arrange
ment of openings as at l5 which enable the mech
10'
anism to be inspected and parts replaced when
necessary.
,
The counting mechanism comprises a series of
dials, preferably three in number, identi?ed at 15
i8, i1 and i 8 as shown, each of which. consists of a
circular disc rotatively journalled in the casing in
overlapping formation. Each dial bears digits
from one to nine and a nought on its outer face
which individually appear to view through the IO0
respective sights as the dial is rotated. The
indicia may be suitably inscribed, such as by litho
graphing or otherwise as is common in the art.
The dial It represents units, the dial i'l tens and
the dial l8 hundreds. The dials are positioned
directly behind the front wall ‘I of the casing in
order that their indicia may, be readily read
through the sights aforementioned, which dials in
the preferred construction of the invention are to
be mounted upon ?xed stub shafts as at l9 by
means of ‘a sleeve~like hub ‘21). Each hub turns
with its dial and presents a long bearing surface
that resists wear and tear. Each dial has a
ratchet wheel 2! integral with or secured to its
hub and provided with ten teeth.
35
The ratchet wheels are individually held against
retrograde movement by resilient detents 22 'at~
tachedto the casing. The ratchet of the unit dial
has a projection at one side in the form of a bent
wire 23 that presents a tooth for turning the
ratchet wheel of the tens dial a distance of one
tooth in each revolution of the unit dial, similarly
the ratchet wheel of the tens dial is provided with
a tooth 24 for fractionally turning the third dial
l8 each time it makes a complete revolution.
The tripping mechanism comprises a quadrant
25 having a pair of spaced side plates attached
to a hub 26 journalled on a ?xed stub shaft 27.
The stub shaft is similar in construction to the
stub shafts I9, all of which stub shafts may be
constructed with a head at the front end and
locked in place at the rear end by means of in
serted wires as indicated at 28. The wires are
arranged to preclude the shafts from turning.
Such construction may of course be modified ac

cording to circumstances.

The quadrant is pro
vided with a curved or circular wall 29 united
with the aforesaid side plates and presenting an
arcuate face substantially on an arc whose centre
is common with the axis of the quadrant. A
pull chain 39 is applied over the curved face of
the quadrant and has its upper end attached
thereto at 3| and extends downwardly through
a member 32 providing a guide passage there
10 for. The chain extends'for a suitable distance
below the casing and carries a pick 33 for the
purpose of resetting the counting mechanism, as
number of times to bring the nought into register
with the respective aperture in the front wall of
the casing. The tens dial is then re-set by in
serting the pick 33 in one of the apertures 4|
exposed through the respective slot in the casing
and urging the dial forwardly in the direction of
the arrow head. This operation is repeated a
su?icient number of times to bring the nought
into register with the respective casing sight.
The hundreds dial is reset in a similar manner.
What I claim is:
l. The combination in a tally keeper, of a cas
will be hereinafter explained.
‘The ?exible element 30, upon being pulled,
15 turns the quadrant about its axis imparting a
ing including an apertured bottom wall, a ratchet
wheel journalled in the casing for operating a
counting mechanism, a quadrant in the casing
fractional turn thereto. The quadrant carries a
trip dog 34 pivoted on an axis extending between
the upper parts of the side plates thereof and
having its distal end inwardly curved as at 36
20 to engage the teeth of the unit ratchet wheel 2|.
An arm 3? radially extends from the ‘trip dog
below the ratchet wheel and composed of a pair
of spaced side plates connected by a pivotally
mounted hub, and a curved wall attached to the
at its pivotal axis and is angularly disposed with
respect of the length of the trip dog. This arm
is connected to a tension spring 38, which in
25 turn is connected to a Wall of the casing. The
spring not only functions to urge the trip dog
into contact with the teeth of the ratchet wheel
but also retracts the quadrant to its normal po
sition following a pulling operation. Means are
30 provided to limit the oscillatory movement of the
quadrant, which means consist of prolonging the
side plates of the quadrant to compose ?ngers 39
adapted to abut a wall of the casing in the re
tarded position. The members 39 thus are held
35 in abutment with the casing by the spring 3'!
in the normal position of the quadrant and when
the quadrant is advanced a forward limiting stop
is provided by the engagement of the edge 43 of
the curved part 29 which contacts the casing, as
40 shown in Figure 5. The quadrant has a move
ment about its axis suf?cient to enable the trip
dog to advance the unit ratchet wheel a distance
of one tooth each time the chain is pulled. It
will therefore be evident that when the tripping
45 mechanism has been actuated ten times, the unit
dial will have made a complete revolution and
the tens dial will have been turned a distance of
one-tenth of a revolution.
The re-setting mechanism comprises a series
50 of equally spaced circumferential apertures 4|
arranged in the dials ll‘ and is in accordance
with the spacing of the teeth of their ratchet
wheels. Two adjacent apertures of each of these
dials are accessible by means of arcuate slots 42
65 in the front wall of the casing, which slots ter
minate preferably in an arrow head in order to
indicate direction of movement. In re-setting
the counting mechanism, the unit dial is ?rst
turned to zero by pulling the chain a sufficient

wheel, an arm radially extending from the pivot
point of the trip dog, and a tension spring con—
necting said arm to the casing and so directed as
to retain the trip dog in contact with the ratchet
wheel and to retract the quadrant.
