Mark M. Hennessy, Milwaukee, Wis., assignor to
Durant Manufacturing Company, Milwaukee,
Wis., a corporation of Wisconsin
Application October 25, 1937, Serial No. 170,775
5 Claims. (Cl. 235-117)
especially adapted to register the successive oper
My present invention relates in general to im
provements in the construction and operation of ations of various types of machines or mecha
registering devices for indicating or registering nisms, it is not the intent to thereby unnecessarily
successive operations of a machine or the like,
5 and relates more speci?cally to an improved sup
port or mounting for such devices.
Generally defined, an object of this invention is
to provide an improved registering device or unit
which is extremely durable and compact, and
which may be readily installed for cooperation
with the machine with which it is to be used.
Another object of the invention is the provision
of an improved mode of mounting counter units or
the like, so that a complete counter assemblage
may be conveniently installed in a bored hole in
the machine with which the unit cooperates, and
will thereafter be effectively protected against
damage.
a
A further object of my invention is the provi
sion of an improved registering unit comprising a
series of concentric counter wheels mounted on
one shaft and a like series of motion transmitting
pinions mounted upon another shaft, the two
shafts being supported in a circular cage which
5 con?nes and protects the wheels and pinions,
while at the same time providing a durable sup
port for the mechanism.
Still another object of the invention is the pro
vision of a simple and compact registering assem
30 blage having neat appearance, and which may be
manufactured and installed at moderate cost.
These and other objects and advantages of my
present invention will be apparent from the fol
lowing detailed description.
A clear conception of one embodiment of my
present invention, and of the mode of construct
ing. installing and of utilizing registering devices
built in accordance with the improvement, may be
had by referring to the drawing accompanying
and forming a part of this speci?cation wherein
like reference characters designate the same or
similar parts in the several views.
Fig. l is an outside view of one of the improved
registering units completely assembled;
Fig. 2 is a longitudinal section through the sup
porting housing of the unit of Fig. 1, taken along
the line 2--2 of Fig. 3;
Fig. 3 is an end view of the registering assem
blage with the closure cover removed;
Fig. 4 is a transverse section through the unit,
taken along the line 4-4 of Fig. 2; and I
Fig. 5 is another transverse section through the
assemblage, taken along the line 5-5 of Fig. 2.
While the invention has been illustrated herein
55 as being speci?cally embodied in a_counter unit
restrict the scope, since some of the improved
features may be susceptible of more general appli 91
cation.
Referring to the drawing. the improved regis
tering device shown therein comprises in general
a main housing or casing 8 having therein a cir
cular hole provided with opposite end bores 9, It,
the casing also being provided with a lateral sight
opening ii and with a readily removable cap i2
normally directly enclosing the outer end bore It;
a counter unit confined within the circular hole of
the casing 8 and including a frame or cage i3 pro 15
vided with circular end heads or portions It, IS
snugly fitting the casing bores 9, l0 respectively, a
series of counter wheels i6 rotatably supported
upon a shaft l'l eccentrically mounted in the end
heads l4, l5 and being visible through the opening 20
H, and a like series of motion transmitting pin
ions 18 rotatable upon a second shaft It also
eccentrically supported in the end heads H, l5;
and gearing for driving the counter unit and also
being housed within the main casing 8.
The main casing 8 may be a part of the frame of
the machine with which the registering device is
intended to cooperate, and is preferably formed of
one piece of metal having the counter unit receiv
ing hole formed directly therein either by coring 30
during casting, or by drilling and boring. The
sight opening it of the casing 8 may be provided
with a protecting shield 20 and a transparent
covering 2i as shown in Figs. 1 and 4, in order to
exclude dust and dirt, and the end cover or cap I!
may be detachably secured to the end of the
casing B in any suitable manner so as to further
exclude foreign substances while permitting con
venient access to the counter assemblage.
The frame or cage i3 is also preferably formed
from a single piece of metal, and the end heads It,
ii are rigidly interconnected by means of spaced
bars 22 formed integral with these heads, and
between which the counter wheels l6 and pinions
l8 are disposed. The end head or portion H of
the cage i3 is of lesser diameter than the oppositr
end head i5, and as previously stated, the portions
M, ii ‘are formed to snugly fit the casing bores 9,
ill respectively. The cage end head i5 is provided
with a peripheral notch 23 which is adapted to
coact with a pin 24 secured to the main casing 8
as shown in Fig. 3, in order to prevent rotation ~ '
the cage i3 relative to the casing 8 when
assembled.
The shafts l1, it upon which the counter 56
2
2,127,295
wheels I6 and the pinions II are rotatably
mounted, are fixed against rotation relative
to the cage II and are located on opposite sides
of the axis of this cage between the bars 22,
see Figs. 2 and 4. The outer end of the shart I!
may be disposed sufficiently close to the closure
cap_l2 so as to prevent endwise displacement
In
the extreme ends of the bores 8, l0, respectively.
By virtue of the fact that parallel shafts 11, II
are so disposed that the periphery of the counter
wheels and of the plnions which cooperate there
with are located well within the periphery of the
of the cage I3 relative to the casing 8, or the
cage I! may be held in place by a removable
substantially cylinder cage 13,‘ this removal and
cries of the wheels 16 and of the pinions I!
are located within the external diameter of the
9, l0, so as to insure proper coaction of the worm
wheel 28 with the worm 3H, and after the cage II
insertion of the cage is entirely unobstructed and
dowel pin. The disposition of the shafts l1, I9 may be freely accomplished. The end heads H, I!
is obviously such that all portions of the periphe ,should snugly fit the corresponding casing bores 10
end head l4, thereby permitting unobstructed
insertion and removal of the counter cage and
mechanism relative to the bores of the casing 8
when the cover or cap I! has been removed.
The number bearing counter wheels I6 which
are rotatably supported upon the shaft H in
alinement with the sight opening H, are of
relatively well known and standard construc
ticn, and each of these wheels has an end gear
25 which cooperates with the adjacent pinion
I8 on the shaft IS in such a manner that each
of the successive higher numbered wheels l6 will
. make only one-tenth of a revolution for each
complete revolution of the preceding wheel Hi.
In the counter wheel assemblage specifically
30
and the worm wheel 28 will automatically engage
the worm 30 when the end heads #4, l5 enter
shown herein, there are several dead or blank
wheels 26 interposed between the digit number
bearing wheel of lowest order, and the driving
mechanism, and motion is transmitted to the end
wheel 26 through a sleeve 21 which surrounds~
the shaft l1 and is‘journaled in the end head IL
The driving mechanism which imparts motion
to the counter unit, comprises a worm wheel 28
secured to the outer end of the sleeve 21 by
means of a pin 29, and a worm 30 meshing
with the worm wheel 28 and secured to the end
~11) of a driving shaft 3| journaled in a sleeve 32
‘which is detachably secured to the main casing
8. The sleeve 32 is of suilicient external diam
eter to permit removal of the worm 30 from with
in the casing 8 when the sleeve 32 is removed.
When the improved registering device has been
properly assembled, the driving mechanism which
is located within the casing here or recess remote
from the open end thereof, is adapted to impart
rotary motion to the counter wheels I6, 26,
through the sleeve 21 and through the pinions 28,
in a well-known manner. The shaft 3| may be
connected with any desired type of machine or
mechanism, and may be either continuously or
intermittently rotated. The numerals of the
counter wheels 16 'will be clearly visible through
the transparent closure 2| of the opening II, and
the cage i3 will be prevented from rotating by the
pin 24 coacting with the notch 23 of the cage.
The cover I! will normally be in position and will
60 cooperate with the transparent closure H to pre~
vent ingress of dust or dirt.
When it becomes desirable to dismantle the
mechanism by removing the counter unit, it is
only necessary to remove the cover l2 and to with
65 draw the cage l3 together with the counter mech
anism, as a unit, from within the casing bore
through the open end thereof. The worm wheel
28 will then disengage the worm 3D, and the latter
may thereafter be removed from within the eas
ing 8 together with its shaft 3| and bearing sleeve
32. Assembly of the mechanism is just as simple.
The cage '3 with the counter mechanism as
sembled therein, may be readily inserted into
the bore of the casing 8 through the open end
. oi the latter, after the cover l2 has been removed,
has been inserted, provision should be made for
preventing endwise shifting thereof.
‘ From the foregoing specific description it will
be apparent that the present invention provides
an extremely simple ‘mounting for a relatively
compact registering unit, and that the unit after
insertion is well protected against possible dam 20
age. The unit may, however, be quickly as
sembled and inserted within or removed from the
casing bore, and by providing an integral or
one~piece casing 8, adequate protection of the
relatively delicate mechanism is assured. The
circular formation of the cage and the eccentric
disposition ofythe counter wheels, pinions, and
supporting shafts within the circular cage, facil
itates construction and assembling of the device,
25
and the improvement has proven highly success»
ful in actualcommercial use.
- It should be understood that it is not desired
to limit this invention to the exact details of
construction or to the precise mode of assembling,
herein shown and described, for various modifica
tions within the scope of the claims may occur
to persons skilled-in the art.
