Application March 13, 1936, Serial No. 68,618
19 Claims. (Cl. 198-220)
This invention relates to improvements in invention, connected to a conveyer pan line, with
drive mechanisms for shaker conveyers of the parts of the pan line broken away;
type utilized for conveying loose material such

vention;
More speci?cally the presentinvention is di
rected to improvements in construction of the
10 type of mechanism disclosed in my prior applica
tion, Serial No. 746,979, ?led October 5, 1934,
which matured into Patent No. 2,077,593, and has
as one of its objects to provide a drive whereby
the conveyer pan line may be driven from rock
15 ing arms and puller arms rather than directly
from a rotatable crank and pitman, which mech
anism is arranged in a novel manner to effect a
drive wherein the direction of coal travel may be
reversed under control of the operator.
20
Another prior application, Serial No. 57,730,
?led January 6, 1936, shows a variable conveyer
drive mechanism wherein a crank, rotatably driv
en at a variable angular velocity, reciprocably
drives a conveyer pan line by means of a rocking
25 member rocked‘ by a connecting rod journaled on
said crank. The device of my present invention
differs from the device of my prior application in
that it is reversible and in that the variably ro
tatable drive mechanism and connecting rod are
30 so arranged that the driving effect of the con
necting rod is relatively moderate and is added to
the driving effect of the variably rotatable‘crank
when arranged to convey material in a forward
direction and subtracted from the driving effect
35 of said crank when arranged to convey material
in a reverse direction. This results in a drive
mechanism so arranged that the driving effect of
the crank is ‘greater when the variably rotatable
drive mechanism is arranged to convey material
40 in a reverse direction than in a forward direction
so that the driving effect of said rotatable drive
mechanism in a reverse direction may counteract
the driving effect of the connecting rod in a for
ward direction and attain a ?nal conveying effect
45 of the mechanism which will be the same for
similar settings of the drive mechanism in both
forward and reverse directions.
Other objects of my invention will appear from
time to time as the following speci?cation pro
ceeds.

My invention may be more clearly understood
with reference to the accompanying’ drawings
wherein:

Referring now to the drawings which illustrate
a preferred embodiment of my invention, a
shaker conveyer drive mechanism, generally in
dicated by reference character I0, is provided.
Said drive mechanism is mounted on a base plate
I I which is adapted to be held in position on the
mine bottom in the usual manner; as, for in
stance, a plurality of mine jacks at the corners
thereof and indicated generally by reference
characters I2, I2.
The general arrangement of the drive mecha
nism and the details of the gear reduction mech
anism utilized therein are similar to those shown
and described in my aforementioned prior appli
cation, Serial No. 746,979, (Patent No. 2,077,593),
but as all of said parts cooperate to produce the
desired variations in shaking motions including 50
reversal thereof, said parts will herein be brie?y
described.

s
A casing I 3 is mounted on the base plate I I in a
suitable manner as by welding and comprises a
cylindrical portion I4 serving as a support and
2,123,685
housing for planetary gear reduction mecha
nism, generally indicated by reference character
I5, and a forwardly extended portion l6 which
forms a bearing support for a transversely dis
posed rocking shaft | ‘I.
Said rocking shaft is provided with a pair of
rockingarms l8, _l8 disposedat opposite-ends
thereof and herein shown as extending upwardly
34 and inwardly towards the center thereof and
is journaled on a shouldered hub 45 formed in
tegral with the side wall 38.
A spider 46 abuts the opposite face of said in
ternal gear and is secured thereto by means of OX
suitable nuts and bolts 41, 41.
Said spider is
provided with a hub 49 which is journaled on a
shoulder 5ll-of the rotatable support member 28
therefrom. Said rocking arms are adapted to and arranged coaxial‘ with the axis of rotation 10

The rocking arms l8, I8 and rocking shaft I11 - rotation of said cage will be increased, and when
are rocked by means of a rocking arm 2| keyed said internal gear is rotated in an opposite direc

tion, the speed of rotation of said cage will be
from said shaft. Said rocking arm is‘rockedby
a variably rotatable crank 22 by means of a
decreased; 1
relatively long connecting rod 23. It should here
in be noted that the cranki22, connecting rod 23
and rocking arm 2| are‘so arranged that said
crank will rock said rocking arm atequal angles
25 to a line extending through the center of the
rocking shaft l1 and disposed perpendicular to
the longitudinal center line of the , connecting
rod 23 when in a dead center'position. The‘rock
ing arms I8, l8 will in turn be rocked at equal
30 angles to a line extending through the rocking
center of said arms and perpendicular to- the
longitudinal center line of the puller arms |9
when said puller arms are at either of the ex
treme ends ‘of their stroke; The purposelof this
arrangement is to'moderate'the conveying effect
of said connecting rod and rocking arms as much
Referring now particularly to the mechanism
for changing the angular velocity of the crank
22'which mechanism forms a part ofthe subject
matter of the present invention, the same com
prises a novel~arrangement for rocking the in
ternal gear 43 alternately in opposite directions
during each revolution of said crank in such a
manner that the variation in angular velocity of
said crank will be greater when the parts are ar
ranged to convey material along the trough line
in one direction than in anopposite direction in '
order to counteract the tendency of the connect
ing rod 23 to move material along the trough line
in a forward direction when the conveying action
of the crank '22 is reversed.

The crank 22 isjournaled'at one of its ends in
a suitable‘ end plate “for the casing l3 and has
a cage 25 of the planetary gear mechanism "15
As herein shown, my improved mechanism in 35

shaft for the crank 22 and disposed 90° out of

on the hub of said cage‘and'engaging a shouldered
bearing surface 21 formed in a supportmember
28 rotatably mounted in the cylindrical portion M
of the casing‘ l3.
The crank 22 and planetary gear mechanism l5
are driven from a suitable motor 29'secured to
one end wall of the casing ‘ l3 in a usual manner.
50 Said motor is herein shown as beingof the elec
tric type having a ?ywheel>30l5keyedon its motor

fluctuations'in speed of said motor.- Said‘motor
is provided with a motor pinion 3| which meshes
with and drivesan idler gear 33. Said idlerigear
meshes with and drives a spur gearv 34-'on a shaft
35. Said shaft, is journaled'at one of its ‘ends
in'an end plate 35 disposed oppositelyfrom-the
end plate 24 and is journaled ‘intermediate its
00 ends in a suitable bearing member 31 supported
in a side wall 38 of said casing. Said shaft has
a spur gear 39 keyed to its inner end which spur
gear forms a sun gear for the planetary gear‘re

spaced shafts 4|, 4| which shafts are's‘ecured-‘at
their ends in the cage 25'in'a usual‘manner'. Said
pinions mesh with an internal ring gear‘ 43 which
70 serves as a reaction vmember for~the planetary
gear reduction device. The‘ outer periphery and
side of said ring gear adjacent the end-plate36
abuts a shouldered portion of a rotatable support
member 44.» Saidsupport member'extends out
75 wardly over the sides of the cage 25-and sun-gear
In my improved construction, the crank 53 has
bearing in an anti-friction bearing member 54

Figures 2 and 3).
The oscillating'frame 51 is provided with a
hollow annular extension 59 surrounding the
crank 53. This annular extension forms a hub
for a rocking. member 60 rotatably mounted
thereon and provided with a pair of oppositely
disposed extensions 6| and 62. One of these ex~
tensions BI is pivotally. connected by means of
a relatively short link 63 to a projection64 of the
rotatable support member 28. Said rotatable it' 3
support member is mounted within the cylin
drical portion M of the casing I3 for rotatable
movement with respect thereto‘ and has worm
teeth formed on its outer periphery. Its general
arrangement and function is similar to that-of the
worm gear rings previously employed in drive
mechanisms of the same type illustratedby my
prior application, Serial Norv 746,979, (Patent
No. 2,077,593), namely, to change the angular
position of the rocking member 60 with respect to
the oscillating frame 51 so as to control the vio
lence of the shaking action, and also‘ by suitable
adjustment, as will presently appear, to re
verse the direction ofshaking movement.

wardly from the spider 46 forming a support for
the internal gear 43, as previously described,

than the link 63 and extends in the same general
direction as the link 63. Said projection extends

move along it when it is disposed along the level.
The foregoing is true with the device herein il

crank 22, however, has a conveying effect when
rotated at a uniform angular velocity which is due
to angularity of its movement with respect 10
to the trough, but this is only sufficient to cause
material to- move along the trough line when in
clined down grade. The connecting rod 23 and
‘H of the cylindrical portion M of the casing l3,

effect. The ?nal conveying action when these 15

which is manually controlled by a hand wheel 12.
A locking means is provided for restraining the
rotatable support member 28 from rotation. In
the form shown, said support member is provided
with a plurality of apertures, indicated by ref
erence characters ‘l3, 14, ‘I5, 16, 11 and 78, re
spectively, which are placed at suitable intervals

conveying effect of the connecting rod 23 and
rocking arms 2! and I8, however, is not reversed

'22 so is still in a forward direction. Thus, when
30 apertures are adapted to be selectively engaged
by a spring-pressed plunger 19 mounted in a lug
8|! extending outwardly from said casing (see
Figures 4, 5 and 6).
The plunger 19 is disengaged from any of said
535 aforementioned apertures by means of a pair of
spaced lever arms 8| actuated by an operating
lever 82 (see Figure 1). The free ends of said
arms engage the lower ends of projections 83,
83 extending inwardly from a member 84. Said
member is secured to the outer end of said plung
er and extends inwardly along opposite sides of
the lug 8B.
'
It will be manifest that the greater the arc of
movement of the internal ring gear 43 during
45 each revolution of the crank 22, the greater will
be the variation of the angular velocity of the
crank 22 and the steeper will be the line of the
velocity curve, indicating the deceleration of the
forward stroke resulting in an increase in mate
50 rial travel along the trough line with a corre
sponding increase in stresses on the drive.
It will be observed in Figures 4 and 5 particu
larly, that the effective arc of rocking move
ment of the internal ring gear 43 may be con
55 trolled by rotation of the rotatable support mem_
ber 28 through manipulation of the hand wheel
12. In Figure 4, the parts are positioned so that
?nal velocity curve will be similar to curve A in
Figure 9, and movement of said support member
the rocking member 69 is in this last-mentioned 30
position, the ?nal conveying eifect of the drive
will be the conveying effect of the connecting rod
23 and rocking arms I 8 and 2| subtracted from
the conveying effect of the crank 22. When the
support member is midway between the apertures 35
75 and ‘Hi, the conveying effect of the crank 22
in a reverse direction will be neutralized by the
conveying eifect of the connecting rod 23 and
rocking arms l8 and 2 i. The velocity curve of the
drive will be similar to that indicated by curve :40
B. of Figure 9, and the trough line will have no
conveying effect, except when inclined down
grade.
Further rotation of said rotatable support
member in the same direction will reverse the 45
direction of movement of said internal gear and
change the phase of the peak of the acceleration
curve so it will occur in the ?rst 90° of the cycle
of rotation of said crank.
Still further rotation
of said support member will gradually increase 50
the arc of movement of said internal gear and
thus increase the effectiveness of the drive action
in a reverse direction until a point is reached
where the plunger 19 may engage the aperture 55
18 at which point the drive action will be the
same as indicated by curve A of Figure 9, but in
a reverse direction and indicated by curve C‘ of
Figure 9.

in Figure 4 will result in a gradual decrease in the
arc of movement of the internal gear 43, which
will decrease the effectiveness of the conveying
action until a point is reached where there will
65 be no rocking movement of said internal gear.
It should be understood that a crank driven at
a uniform angular velocity and connected to a
conveyer trough by means of a connecting rod
will reciprocably drive the trough, but the motion
70 of the trough will be such that there will beno
movement of material along it except when in
sirable that the conveying effect of the rocking
clined down grade. If, however, the connecting
rod is relatively short and its free end is connected
to a rocking member which in turn is connected

the arc of movement of the internal gear 43 ‘and
thus increasing thev variationin angular velocity
of the crank‘22."
'
This increasein the arc of movement'of said in;
ternal gear,‘ when said -‘ rocking memberisina
reverse position,“ is attained by arranging the
parts so thatithe vertical component ‘of-move
T15 ment of said internal gear is less ‘for'a'forward
position than for a corresponding reverse po
sition, so that the ?nal conveyingeffectrof the
drive will be the same in either a forwardor
reverse direction, as may clearly be seen with
reference to Figures 4 and 5.
Thus, when the parts are positioned; as shown
in Figure 5,- the ?nal conveying action of the drive
will be the same as when positioned as shown
in Figure 4, but‘ in a reverse-direction and=~will
be the conveying effect of the crank 22, minus the
conveying effect of the connecting rod 23 and
rocking arms 2| and I8.
As a further feature of my'improved ‘construc
tion, I provide novel means for indicating the
30 position of the parts‘ and violence of-the drive
when the rotatable support member 28 is in its
various positions of adjustment. As herein
shown, a housing member 86 is mounted on the
upper side of the cylindrical portion M of the
casing l3 by means of cap screws 81, 81' (see
Figures '7 and 8). Said housing ‘member has an
indicating pointer 88 mounted thereon for trans
lational movement with respect thereto. Said
pointer is connected at its inner end to a mem
ber 89 slidably guided in said housing member.
The member 89 has a depending portion 90 which
is slidably mounted in a spiral groove 9| formed
in the outer periphery of the rotatable support
member 28. Suitable characters or letters are
herein shown as being provided on the outer face
of the housing member 86, as is best shown in
Figurer'i, so said indicating pointer may, indicate
the position of the parts when the plunger 19 is
engaged with any of the apertures 13 to "I8, in
elusive, and thus indicate the violence of’ the con
veying action and the direction of material travel
along the pan line.
While I have herein shown and'described one
form of my invention, I do not wish to be lim
ited to the precise details of construction or‘ar
rangement of parts herein shown and described,
excepting as speci?cally'limited in the appended
