LOADING MACHINE
Frank Cartliclge, Chicago, 111., assignor to Good
man Manufacturing Company, Chicago, Ill., a
corporation of Illinois
Application November 21, 1935, Serial No. 50,861
7 Claims. (01. 198-8)
This invention relates to improvements in load
ing machines of the type adapted to gather and
load loose material such as coal from the ground,
and more particularly to the gathering element
5 for initially picking up the loose material and
moving it onto a conveyer for discharge into cars
or the like.
The principal objects of my invention are to
provide a gathering element of the character de
10 scribed, especially designed to handle material
such as ‘coal in a more e?icient manner than
formerly.
‘
In carrying out my invention, I utilize the same
general principle of clearing the gathering means
from material on the conveyer at the upward
turning point, as is disclosed in the Shanaberger
Patent No. 1,680,695, and in a prior application,
Serial No. 48,189, ?led November 4, 1935, but im
prove upon the means for raising the gathering
20 arms above the conveyer as they move therealong
by eliminating the possibility of trapping coal be
tween the arms and the raising means and by
arranging said means so that the gathering means
will carry a minimum amount of coal beyond the
25 conveyer as it turns away therefrom.
My invention may be more clearly understood
with reference to the accompanying drawings,
wherein:
Figure 1 is a view in side elevation of a loading
30 machine of the track-mounted type, illustrating
one form in which my invention may be embodied;
Figure 2 is an enlarged side elevation of the
gathering and loading element shown in Figure

certain details of my invention;
~
Figure 3 is an enlarged plan view of the load
ing element of the machine shown in Figure l,
with certain parts broken away and shown in
section in order to illustrate certain details of my
invention, not shown in Figure 2;
Figure 4 is an enlarged sectional View taken
substantially along line ll—4 of Figure 3;
Figure 5 is an enlarged sectional view taken
45 substantially along line 5—-5 of Figure 3;
Figure 6 is an enlarged sectional View taken
substantially along‘ line 6—6 of Figure 3;
-
Figure 7 is an enlarged sectional view taken
substantially along line l—'l of Figure 6; and
50
Figure 8 is an enlarged side elevation showing
a modi?ed arrangement of the apron between the
gathering means.
In the drawings, my invention is shown as be
ing embodied in a loading machine of the track
mounted type, the main elements of which are
essentially the same as shown inmy prior ap
plication, Serial No. 682,248, ?led July 26, 1933,
which. issued as Patent No. 2,066,137 on Decem
ber 29, 1936. In the form shown, the loading ma- -
chine consists generally of a wheeled truck or. UT
main frame [0 having a horizontally and vertical
1y swingable gathering and loading element H
mounted at the forward end thereof and extend
ing forwardly therefrom, and a discharge con
veyer l2 extending from beneath the rear end of .
said loading element and upwardly and rearward
ly therefrom. Said discharge conveyer is ar—
ranged to overhang the rearward end of said main
frame for discharging material into suitable re
ceiving means, such as mine cars or the like.
The gathering and loading element ll may, as
usual, comprise an inclined conveyer frame I4
pivotally supported between transverse trunnion
supports l5, l5. Said trunnion supports are dis
posed at the forward end of said main frame and 20
are pivotally movable with respect thereto about
a vertical axis to permit said conveyer frame to
swing in a horizontal plane. The mechanism for
effecting swinging movement of said trunnion
supports and for pivotally swinging said conveyer
frame on said trunnion supports is not herein
shown or described since it forms no part of my
present invention and is fully disclosed in my
aforementioned application,‘ Serial No. 682,248,
30
now Patent No“ 2,060,137.
Thev inclined conveyer frame 14 includes a
trough-like conveyer section l6 and a forward
gathering section ll connected thereto in a suit
table manner. Said forward gathering section
has an apron I8 extending laterally beyond op 35
posite sides of the conveyer trough section and
downwardly therefrom in an inclined plane so
that the‘ forward end thereof may engage the
ground.
A plate l9 forms the bottom of the conveyer
section l6. Said plate extends forwardly in an
‘inclined plane which, as herein shown, is sub
stantially parallel with, but below the upper sur
faces of the apron [8 at the forward end of said
45
inclined conveyer frame.
The moving parts of the conveyer consist of a
pair’ of parallel-spaced endless chains 20, 20 hav~
ing material engaging ?ights 2 I, 2| carried there
between at suitable intervals. vThe lower run of
said chains extends downwardly beneath the 50
plate l9 over adjustable idler rollers 24, 24 for
taking up excessive slack in said chains, under
idler rollers 25, 25, and around sprockets 26, 26
on a transversely extending shaft 21 immediately
forwardly of the front margin of the plate I9._ 55
2
2,135,882
From thence said chains move upwardly over said
plate on guide rails 28, 28 disposed along opposite
sides of said plate.
Immediately in front of the sprockets 26, 26 is
a curved plate 29 substantially conforming to the
form of the chains 20, 20 as they round said
sprockets, and terminating at the delivery edge
of said inclined apron, which edge is herein shown
as being forwardly of the shaft 21. A bottom
10 plate 32 extends across the bottom of the forward
end of said frame, and the forward edge of said
apron and said bottom plate are notched adja
cent the central portion thereof, as is'indicated
by reference character 33, to-eliminate a dead
15 space between said gathering arms in the central
portion of said apron in a manner which has been
described in a prior application, Serial No.
580,755, ?led December 14, 1931-, now Patent
No. 2,073,142.
It should herein be noted that the angle of
deposited thereon, said means includes an ar
rangement whereby said conveyer is moved faster
than said arms, so as to move material away from
the arms and also includes an improved means
for raising said arms above the conveyer at their
outward turning point utilizing the same princi
ples disclosed in the Shanaberger Patent No.
1,680,695. As herein shown, each gathering arm
31 is pivotally connected to the chain 35 by means
of a pivotal pin 54 secured at its ends to a pair of 10
spaced lugs 55, 55 extending outwardly from suit
able links of said endless chain (see Figures 2
and‘3)‘.
The pivotal axis of said arms, as herein
shown, is parallel to the path of travel of the
chain 35 to permit the arms to be pivoted up— 15
wardly with respect to the apron | 6.
Said gathering arms are lifted away from the
coal on the conveyer at their upward turning
point by means of a cam member 56 extending
upwardly along the inner side of each apron from 20
a point disposed adjacent the forward- end- of
‘inclination of the bottom plate 32 withrespect

cam member is inclined downwardly towards the
conveyer and gradually decreases with respect to
a horizontal-plane as-saidcam member extends
along the conveyer for raising the gathering arms
rearwardly of the forward end-of said apron may
clear the ground and said apron may follow an
uneven bottom and be more readily wedged under
the material it is desired’ to load.
The gathering means consists of a pair of end
less chains 35, 35 orbitally guided in chain guides
36, 36 and having a‘ plurality of gathering arms
31, 37 extending laterally therefrom. Each of
said chain guides-is mounted on the apron |8
and extends along opposite-sides'of the conveyer
from points disposed forwardly of the forward
end thereof in rearward diverging paths, so that
said gathering arms- may diverge laterally away
40 from the conveyer as they extend therealong and
swing in paths extending forwardly beyond sai
apron at their lower turning point.
'
The drive for each of the endless gathering
chains 35, 35 includesa drive sprocket 39 mounted
45 on each end of the shaft 2‘! outwardly from the
sprockets 26, 26'. Each sprocket 39 drives apar
allel-spaced sprocket 40 on a transversely extend
ing shaft “by means of a drive chain 43. The
shaft Al is journaled-at its inner end in a suitable
ball bearing 44 mounted in the upper and lower
halves of a housing and bearing support member
45. Said housing is secured to the sidesof the
‘conveyer frame I4 andis split in an inclined
plane which is herein shown as substantially par
allel to the plane of the conveyer, so said chain
and sprocket and parts driven therefrom may
readily be accessible for inspection or repair.
The outer end of said shaft is mounted in a bear
ing 46 carried in a bearing support member 41
60 extending across and mounted in the upper half
of the housing 45. A bevel pinion 48 is keyed on
the shaft 4| outwardly from the sprocket 40 and
meshes with and drives a bevel gear 49 keyed on
the lower end of an upstanding shaft 50. Said
65 shaft ismounted at one of‘ its ends in ‘the hous
ing 45 on a suitable bearing 5| and is mounted
at its opposite end in a bearing 52, which bear
ing in turn is mounted in an upper portion of
the chain guide 36. A sprocket 53 is keyed to
70 said shaft intermediate the bearings 5| and 52
and meshes with the endless chain 35 for driving
said chain.
Referring now in particular to the novel means
for clearing the gathering arms from material
75 on the inclined conveyer, after the latter has ‘been
to a-maximum as they turn away from the con
veyer. Said cam members being inclined to
30
wards the conveyer, permit material whichmight
fall thereon or be moved thereon by said gather
ing arms to slide down the inclined surface
thereof onto the conveyer.
Each gathering arm 31 is provided with an in
wardly disposed engaging end 51 disposed be
neath its pivotal axis, which engaging end is
herein shown as being formed integral with said
arm.
Said engaging ends of said arms are 40
adapted to-engage the engaging face of the cam
member. 56 to cause said arms to gradually rise
above the conveyer as they move therealong.
A ?at cam member 59 is provided for support—
ing each gathering. arm as it turns away from the
conveyer and moves downwardly along ‘the outer
edge of the apron I8.
As herein shown, said ?at
cam member extends around and conforms to the
rearward endlof'the chain guide 36 and its rear
ward portion is formed substantially like the in
side of a segment of a truncated cone.
As said
flat cam member extends downwardly along the
outer side of the apron l8, its angle of inclina
tion with respect to said apron decreases for- per
mitting the arms to gradually pivot downwardly 55
with respect to said apron and rest on said apron.
It should herein be noted that the cam member
56 overlaps the cam member 59 a slight distance
at the initial turning point of the arms away from
the conveyer, and that said last-mentioned cam 60
member is provided with an entering edge 60
which is so inclined with respect to said gathering
arms that material carried upwardly by said
gathering arms will be de?ected thereby onto the
conveyer, instead of being carried around to the 65
retreating side of the apronin the trough-like
formationformed by said ?at cam member.
Suitable means are provided for positively re
straining pivotal movement of said gathering
arms while traveling downwardly along said apron 70
which operate on a principle somewhat similar
to that shown in my prior application, Serial No.
48,189; Said means includes an abutment or
‘shoulder 6| disposed above the pivotal axis of __
'said'gatheringarm; which is adapted to engage "7'5

ment relative to its plane of travel, and means
The lower side of said chain guiding member is
for positively raising said arms as they approach
adapted to be engaged by the engaging face 51.
It should herein be noted that the upper portion
of the chain guiding member, disposed adjacent
their upper turning point comprising a cam mem
the cam members 56 and 59, is inclined in a
manner corresponding to the angles of ‘inclina
tion of said cam members to permit elevation of
said gathering arms by means of said cam
inclined downwardly towards said conveyer and
10 members.
A direction-changing device '63 having means
rotated thereby for positively restraining pivotal
movement of said arms at their lower turning
point is provided at the forward end of each chain
15 guiding member 36. As herein shown, said di
rection-changing device is in the form of a
sprocket journaled on a suitable bearing member
64 mounted in said chain-guiding member in a
usual manner. A rotatable member 65, such as a
20 disk, is disposed beneath said sprocket and r0
ber extending along said apron adjacent said
conveyer, said cam member having a cam surface 5
adapted to be engaged by abutting surfaces of
said gathering arms disposed beneath the pivotal
axes thereof, and another cam member forming
a continuation of said ?rst-mentioned cam mem- 10
ber at the turning point of said arms away from
the conveyer, said second-mentioned'cam mem
ber being inclined upwardly from said apron in
a direction away from said chain and extending
around the rearward turning point of said gath- 15
ering arms, and said second-mentioned cam
member being provided with an inner edge adja

The modi?ed form of my invention shown in
35 Figure 8 differs from the form previously de
scribed in that the gathering section has two lat
erally extending aprons 6?, 67 at opposite sides
of the conveyer trough section and in that a
channel, generally indicated by reference charac
40
ter 68, is provided between these aprons for mov—
ing material onto the conveyer. Said channel is
formed by a relatively low inclined plate 59, in
clined at a lesser angle with respect to the ground
than said aprons, which terminates at the curved
plate 29 in a plane which is substantially normal
to the conveyer as it turns around the sprockets
25, 28. The forward edge of said inclined plate
is notched in a manner similar to the apron I 8
and the sides of said plate are joined with said
apron in a suitable manner to form a channel
having closed sides leading to the conveyer below
the upper margins thereof.
Thus, material is continuously moved toward
the conveyer along said channel by the gathering
55 arms and the ?nes collected therein form in ef
fect a cushion for the larger lumpsof material
which reduces breakage thereof, as has been pre
viously described in a prior application, Serial
No. 49,004, ?led November 9, 1935, now Patent No.
