Robert C. Osgood and Leslie A. Currier, Clare
mont, N. H., assignors to Sullivan Machinery
Company, a corporation of Massachusetts
Application September 3, 1936, Serial No. 99,228
18 Claims. (Cl. 214-110)
This invention relates to loading apparatus,
and more particularly to improvements in a
loading apparatus especially designed to use with
a hoist operated scraper mechanism.
An object of this invention is to provide an
improved loading apparatus.
Another object
is to provide an improved loading apparatus es
pecially designed to use with a hoist operated
scraper mechanism whereby the material to be
10' loaded may be moved by the scraper into an
elevated position for discharge into a suitable
receptacle. A further object is to provide an
improved loading slide. Another object is to
provide an improved rock loading slide particu
15 larly adapted for use in scraper loading work.
Still another object is to provide an improved
rock loader slide of extremely simple and rugged
construction and low in height. A still further
object is to provide an improved scraper load
ing apparatus wherein but a single rigid hori
zontal boom structure is mounted on a portable
base and has its front and rear end portions
overhanging the ends of the base, the front over
hanging end of the boom structure entirely sup
» porting the hoisting mechanism for operating
the scraper of the scraper mechanism. Other
objects and advantages of the invention will,
however, hereinafter more fully appear.
In the accompanying drawings there is shown
30 for purposes of illustration one form which the
invention may assume in practice.

Fig. 11 is a diagrammatic view showing the
apparatus moving through a curved mine pas
sage with the loading slide swiveled with respect 5
to the base to facilitate movement of the ap
paratus through the passage.
In this-illustrative embodiment of the inven
tion there is shown a loading apparatus of the
type commonly known as a loading slide, espe 10
cially designed to use with a hoist operated scrap
er mechanism, and particularly adapted for load
ing rock in tunnel work.
It will be evident,
however, that the improved loading apparatus
may be used for loading loose material in any 15
suitable type of work, such as loading ore in
mines.
In this illustrative construction there is shown
a portable base I, herein in the form of a truck
frame, mounted on truck wheels 2 adapted to
travel along a trackway 3. Secured to the top
of the truck frame I is a horizontal plate II on
which is swiveled, on a vertical axis at 5, a hori
zontal plate 6. Mounted on the horizontal plate
6 is the improved loading slide generally desig
nated "I, Referring more particularly to the
loading slide, it will be noted that secured to
the top surface of the horizontal plate 6 are chan
nel bars 8, while mounted on the plate 6 and
secured to the channel bars 3 are vertical chan 30
nel bars 9. Superimposed on the base and sup
ported by the vertical channel bars 9 is but a
single rigid horizontal elongated beam or load
ing boom I0 comprising parallel side channel
bars II, I I suitably rigidly secured together, the 35
horizontal boom having its rearward end por
tion overhanging a substantial distance the rear
end of said base and provided with a downwardly
bent forward end overhanging the front end of
the base. Secured to the channel bars II of 40
the loading boom rearwardly of said inclined
overhanging forward end thereof and to the
vertical channel bars 9 are vertical side plates
I3 outwardly flared at the iront of the slide and
in turn having secured thereto a downwardly
and forwardly inclined bottom plate I4, while
arranged between the rearward portion of the
horizontal beam and the vertical bars 9 and
secured thereto is a horizontal plate I5, the
plates I4 and I5 being joined at I6 (Fig. 7) 50
to form a bottom slide, as will later be described.
Fixed to the horizontal beam rearwardly of the
horizontal slide plate I5 are horizontal side plates
Il having their top surfaces iiush with the top
surface of the plate I5, and these side plates co- 5_5
2
2,123,909
operate with the plate I5 to provide a discharge
opening I8 rearwardly of the rear edge of the
plate I5.
As shown most clearly in Fig. 7, horizontally
pivoted at I9 on the forward extremity of the
inclined slide plate I4 is a plate 2€! having a
curved forward end or receiving nose 2| adapted
to rest on the ground surface, while pivotally
mounted on upstanding axes at 22 on the flared
10 portions of the vertical plates I3 at the opposite
sides of the slide are horizontally swingable side
wings 23. The horizontal plate 6, together with
the slide structure carried thereby, are, as above
mentioned, horizontally swiveled with respect to
the base about a vertical axis at 5, and the means
for locking the plates 4 and 6 together comprises
bolts 24 carried by the upper plate 6 and pass
ing through arcuate slots 25 formed in the lower
plate 4, the slots being formed on radii struck
from the center of the pivot 5.
These slots per
mit swiveling of the plate 6 with respect to the
plate 4 when the bolts 24 are loosened, and when
the latter are tightened the plates are locked
together. Mounted on horizontal cross bars 2S
supported by the channel bars 8 are hand wheels
2‘I for operating screw adjusting devices con
nected to usual rail clamps or grips 28 so that
the apparatus may be clamped in a stationary
position on the trackway in an obvious manner.
In this illustrative construction, mounted in a
30
relatively low position on the inclined overhang
ing forward end portion of the beam Il] is a
hoisting mechanism generally designated 30.
The hoisting mechanism is supported entirely by
35 the overhanging front end of the boom wholly
independently of the underlying slide structure.
This hoisting mechanism may be of the same
general character as that described in Patent No.
1,740,707, to R. C. Osgood, patented December 24,
40 1929, although it will be evident that various
types of hoisting mechanisms may be employed.
This hoisting mechanism is of the double drum
type comprising a pull rope drum 3I and a tail
rope drum 32, these drums having respectively
45 wound thereon pull and tail ropes 33 and 34.
The hoisting mechanism is supported on a trans
verse plate 35 secured to the upper surfaces of
the inclined portions I2 of the channel bars I I
and the pull and tail rope drums are driven, as
50 clearly described in the above mentioned patent,
by a motor 3G through suitable gearing under
the control of brake bands 31 and 38, respec
tively. These brake bands are operated by suit
able control levers 39 and 40 conveniently lo
Ui Ui cated at the side of the apparatus. The pull
rope 33 is adapted to extend from the drum 3l
through suitable guides 4I in the form of eye
around this pulley rearwardly beneath a hori
zontal guide roll 49 journaled on a hori
zontal channel bar 50 secured to the forward ends
of the channel bars II in the manner shown in
Fig. 7. The tail rope extends beneath the guide
roll 45 rearwardly into connection at 5I with the
scraper. The opposite sides of the rearward por
tion of the horizontal beam i0 are inwardly and
rearwardly inclined at 52, while the lower sur
faces of the channel bars I I are upwardly and 10
rearwardly inclined at 53. The inclined sides 52
provide clearance for the rearward end of the
beam as the loading apparatus moves through a
curved mine passage.
The mode of operation of the improved load 15
ing apparatus will be clearly apparent from the
description given. A suitable receptacle such as
a mine car 54 is adapted to be placed beneath
the overhanging extremity of the horizontal
beam Ii) directly below the discharge opening I8. 20
The hoisting mechanism may be operated to
move the scraper 46 back and forth toward and
from the pile of material to be loaded, and the
scraper is adapted to engage the material and
drag the material toward the loading apparatus 25
and up the inclined slide until the scraper as
sumes the position directly above the discharge
opening I8 as shown in Fig. '7, the material then
being discharged by gravity from the scraperI
directly into the mine car.
The pivotcd bottom 30
plate 2E! and the pivoted side plates 23 cooperate
to direct the scraper and material to be loaded
onto the slide, and as the scraper moves up
wardly along the inclined portion of the slide it
passes beneath the transverse supporting plate
35 on which the hoisting mechanism is sup
ported. It will thus be seen that the scraper
may be rapidly moved toward and from the pile
of material to be loaded, the scraper moving
directly up the slide of the loading apparatus
and discharging the material directly into the
waiting mine car, thereby eliminating the neces
sity cf belt conveyors and other complicated
mechanism. The swivel type base, as shown in
Fig. 1l, facilitates movement of the loading ap
paratus through a curved mine passage of small
radius, it being possible to swivel the loading
slide with respect to the base as the apparatus
moves through the curved passage. It will also
be evident that by providing the horizontal beam
35
40
45
50
or boom structure on which the scraper slide
lets mounted on the top of one of the channel
way is formed and by supporting the hoisting
mechanism directly on the downwardly inclined
portion of the horizontal beam structure the ap
paratus is rendered extremely low in height. As 55
the scraper moves upwardly along the inclined
slide plates I 4 and I5 into its discharging posi
tion, as shown in Fig. 7, it is guided directly by
bars II, and passes around horizontal guide
these plates, and when the scraper moves rear
60 sheaves ¿i2 and 43, the latter being supported by
a cross frame 44 secured to the rearward ends of
the channel bars II of the horizontal beam. An
opening 45 is formed in the opposite side of the
boom structure so that the guide sheave 42 may
be transposed to the opposite side of the appa
ratus, and the position of the hoisting mecha
nism may be reversed in case a right hand con
trol is desired. The pull rope extends around
the guide sheave 43 forwardly into connection
70 at 46 to a scraper 41 of a conventional design,
herein preferably of the hoe box type. The tail
rope extends from the tail rope drum 32, be
neath a guide roll 48 forwardly of the apparatus,
to a suitable pulley (not shown) located adjacent
75 the material to be loaded, the tail rope passing
wardly beyond the position shown in Fig. '7 60
wherein it overlies the discharge opening I8 it
is guided by the horizontal side plates I'I located
at the sides of the discharge opening. Other uses
and advantages of the improved scraper load
ing apparatus will be clearly apparent to those
65
skilled in the art.
While there is in this application specifically
described one form which the invention may
assume in practice, it will be understood that this
form of the same is shown for purposes of illus
tration and that the invention may be modified
and embodied in various other forms without
departing from its spirit or the scope of the
appended claims.
