This -invention relates to material loading ap
cially adapted to transport through sharply
10 curved, relatively restricted mine or tunnel pas
sageways.
Yet another object is to'provide an
improved rock loading slide especially designed for
use underground in mines or tunnels and hav
ing embodied therein improved means for piv
otally mounting the overhanging rearward por
tion of the slide structure, whereby negotiation
of the apparatus around relatively sharp curves
in the mine or tunnel passageway is facilitated.
A still further object is to provide an improved
rock loading slide having an elongated'rear'
ward slideway-providing structure, and embody
ing means for pivotally mounting the rearward
structure, whereby the same may be swung hori~
zontally during movement of the loading slide
around sharply curved mine or tunnel passage
ways.
Yet another object is to provide an im
proved pivotal mounting for the rearward boom
structure of a rock loading slide, whereby the
rearward boomy portion may be swung both ver
tically and horizontally in an improved manner.
Still another object is to provide an improved
wheel mounting structure for the bottom rear
ward portion of the boom structure, whereby the
rear end of the boom, when the latter is swung
downwardly about its horizontal pivot, may be
guided by trailer wheels running along the mine
or tunnel shaft trackway o-n which the rock load
ing slide is supported and guided, so that the
Itrailing rearward boom portion follows the
40 curvature of the mine or tunnel trackway.
A
further object is to provide' an improved pivotal
mounting for the rear overhanging portion of
the boom of a rock loading slide, whereby the
rearward boom portion may be swung horizontally
in either direction relative to the forward boom
portion. _These and other objects and advantages
of the invention will, however, hereinafter more
fully appear.

- In the preferred illustrative embodiment of the
invention disclosed in Figs. 1 to 6, inclusive, there
is shown a material loading apparatus of the type
commonly known as a rock loading slide especial
ly designed to use with a hoist-operated scraper
mechanism and particularly adapted'to loading
loose rock in underground tunnel work. It will be
evident, however, that the improved loading ap
paratus embodying my invention may‘be adapted
for loading material in any form ,of underground
mining'work wherein the mine passages are rela
tively restricted and sharplyv curved. In this
construction, the invention is shown, for illus
trative purposes, embodied in a scraper loading
slide of the same general character as that dis
closed in the copending joint application of R. C.
Osgood and myself, Serial No. 99,228, filed Sep
tember 3, 1936, now matured into Patent No.
2,123,909, granted July 19, 1938. This scraper
loading slide comprises a portable base in the
form of a truck frame I mounted on wheels 2
adapted to run along a trackway 3 laid on the
mine or tunnel-shaft bottom. Secured to the
top of the truck :frame is a horizontal plate Il, on
which is swivelly mounted at 5 on a vertical axis,
a horizontal turntable plate 6.
Mounted on the
swiveled turntable plate ‘ß is an upstanding frame
work l supporting> a slide structure, generally
designated 8. This slide structure comprises a

supported by the framework l and suitably rigidly
secured together; the front boom portion having
axis of the turntable frame 36 is located a distance
a forwardly and downwardly inclined front end
II overhanging the front end of the truck, in
the manner shown in Fig. 1. The slide structure
on a horizontal pivot to swing vertically relative
to the truck is an upstanding arm structure 38 CII

overhanging, a substantial distance, the rear end
tom of the rearward boom portion I2. Fixed,
as by Welding, to the opposite sides of the chan
of the truck and pivotally mounted on the truck
in an improved manner to be later described.
This rearward boom portion l2 has side channel
nel bars II), Ill of the front boom portion 9 are
rearward projections 4I), 40 to which the rear
bars I3, I3 alined with the channel bars IIB, Iii,
when the rear boom portion is in the position
shown in Figs. 1 and 3. Secured to the framework
-I and the front boom portion S is an inclined bot*
tom plate I4 provided with vertical side plates I5
flared outwardly at the front end of the slide,
while secured to the bottom of the side channel
bars I D, I0 is a horizontal bottom plate I6 co
20 operating with the inclined bottom plate I4 to
form a bottom slideway extending upwardly and
rearwardly along the front boom portion. The
rearward boom portion has a bottom plate l'I
ilush with the bottom plate I5 and forming acon
tinuation of the bottom slideway, and flush with
the bottom plate I'I and extending longitudinally
along the inner sides of the channel bars i3, I3
are horizontal side plates I8, I8 providing guide
ways at the sides of a bottom discharge opening
30 I9 rearwardly of the horizontal bottom plate' l?.
As clearly described in the copendingY applica
tion above referred to, mounted on the down
wardly inclined front end of the front portion of
the boom slideway is a double drum hoist 20
35 which may be of the same general type as that
disclosed in Patent No. 1,740,707 to R. C. Osgood,
patented December 24, 1929. This hoist comprises
a pull rope drum 2| and a tail rope drum 22, and
these drums have respectively wound thereon
40 pull and tail rope or drag-line cables 23 and 24.
The pull rope cable 23 may be extended from its
drum through suitable guides 25 arranged along
the top of the boom slideway, and passes around
substantially rearwardly of the turntable axis 5.
Pivotallymounted on the turntable 36 as, at 31,
boom portion may be attached, as by screws or
bolts 4I. When the attaching bolts are released,
the rear boom portion may be swung downwardly _
about its horizontal pivot 31 by means of capstans
42, 42 arranged at opposite sides of the front
boom portion’ 9 and iixed to a cross shaft 43 jour
naled on the top of the front boom portion, and
this cross shaft has a usual hand crank 44 where
by the capstans maybe rotated. Wound on the
capstans are cables 45, 45 extending along the
sides of the boom structure and guided by guide
sheaves 4‘6 located at the opposite sides of the
front boom portion 9 and attachable at their rear
ends at 4‘I to the rearward end of the rearward
boom portion I2. When the rear boom portion
is in its lower position, as indicated in dotted lines
in Fig.v 1, a pair of track wheels 48 journaled
thereon engage the rails of the trackway 3, there
by to support and guide the rear boom portion as
the loading apparatus moves along the trackway.
When the capstans’ 42 are operated to wind in the
cables, the rear boom portion I2 is swung upward
ly about its pivot 31, and when the rear boom`
portion assumes the position shown in full lines
in Fig. 1, the attaching bolts 4I are replaced to
lock rigidly the rear and front boom portions to
gether.
VIn the modiñed form of theV invention shown,
in Figs. 7 to 10, inclusive, the rear overhanging
boom portion 50 is pivotally mounted at 5I, 5Iv
to the front boom portion of the loading appa
ratus, and these pivotal mountings comprise lugs
52 formed on the front end of the rear boom por
horizontal guide sheaves 26 and 21, the latter
tion and interñtting spaced lugs 53 secured to
45 being supported by a cross frame 28 secured to the
the rear end of the front boom portion, and these
rearward ends of the side channel bars I3, I3 of
the rear boom portion. The pull rope extends
around the guide sheave 2'! forwardly into con
which are insertible locking and pivot pins 54.

mounted in a guide 51 secured to the bottom 'of
-the front boom portion. When one or the other

about the vertical axis 5, and any suitable means, neath the overhanging extremity of the rearward
such as those disclosed in the above mentioned co
pending application, may be employed to lock the
slideway supporting plate to the truck. As also
mentioned above, in accordance with the inven
tion, the rearward boom portion of the scraper
slideway is pivotally mounted. As shown in Fig. 3,

on which is journaled to turn about a vertical
axis horizontally relative to the truck, a swivel

The hoist 20 may then be operated to move the
loading scraper 30 back and forth toward and
from the pile of material to be loaded, and the 70
scraper engages the material and drags the ma
