erate with the ratchet, in order to prevent
the cables 11 from unwinding from the
drums 8 and 10. In other words the pawl
prevents retrogression of the said shaft.
5 Connected. to one end of the pawl 17 is a
p11 cord 18, which passes over a pulley 19
carried by the frame. The other end of the
cord 18 is connected to a lever 20, which is
pivoted at the base of the frame work. This
10 lever 20 is provided with the usual dog 21
to engage the usual form of quadrant 22,
whereby the lever 20 may be held in ad-
justed positions. The lever 20 is also pro-
vided with a hand grip for manipulating
15 the dog 21. Also connected to the lever 20
is the pull cord 23, the upper end of which,
after having passed over the pulley 24 is
connected to a brake lever 25, which is pro-
vided with the usual brake shoe 26. When
20 it is desired to allow the tray 14 to lower, the
lever 20 is oscillated downwardly, thus re-
leasing the spring tensioned pawl from en-
gagement with the said ratchet, which will
permit retrograde movement of the said
25 shaft, thus allowing the cables 11 to unwind
and the cable 15 to wind. At the same time
the shaft is permitted to have a retrograde
movement, the brake shoe of the brake le-
ver is applied against the side of the drum
30 9, by virtue of the pull cord connection be-
tween the brake lever and the lever 20.
The hoisting tray comprises a rectangular
metal frame having two side flanges 13, and
provided with a two part hinged bottom.
35 To hold the two parts 27 and 28 of the
hinged bottom in closed positions cables 29
are provided, which at one of their ends are
connected to one of the side flanges 13, while
their other ends are wound about and posi-
40 tively connected to a revoluble rod shaft 30,
which is mounted in suitable bearings 31 of
the other flange 13 of the tray. Carried by
and rotatable with the rod shaft 30 at one
end thereof is a beveled gear 32, which
45 meshes with a beveled gear 33. The beveled
gear 33 is carried by and rotatable with a
vertical shaft 34, which is arranged at right
angles to the shaft 30 and is provided with
a crank handle 35. The shaft 34 is mounted
50 in bearings 36, as shown in the side eleva-
tion of the hoisting tray. A ratchet wheel
37 is mounted upon the shaft 30 so as to ro-
tate therewith. Engageable with the ratchet
37 is a spring tensioned pawl 38, and con-
55 nected to the pawl is a pull cord 39. By im-
parting a pulling action on the pull cord 39
the pawl 38 will be released from engage-
ment with the ratchet, and by the virtue of
the weight of the contents on the two hinged
60 parts of the tray, the cables 29 will be per-
mitted to unwind from the shaft 30, thus
allowing the hinged parts 27 and 28 to open.
When the hinged parts open, the contents of
the tray will be allowed to dump into the
65 wagon. After the contents are dumped the.rod shaft 30 may be rotated-by virtue of the
crank and the beveled gear connection, so as
to rewind the cables 29 upon the rod shaft
30, thus closing the two hinged parts. When
the hinged parts are again closed the tray 70
may be again lowered in the manner herein-
before stated, for another loading of gravel
or other material.
From the foregoing it will be observed
that a novel form of apparatus for hoisting 75
gravel, or other material for loading the
same into wagons has been devised, and one
which is found to be practical in every phase
of its operations, and also one which is
found to fulfil all the requirements in prac- 80
tical fields.
The invention having been set forth, what
is claimed as new and useful is:-
1. In combination with a hoisting mecha-
nism, a loading tray including two hinged 85
parts, transverse cables attached to one side
of the tray at one of their ends, a rotating
member mounted in bearings at the other
side of the tray about which the cables are
wound, and means for releasing the rotating 90
member, a crank shaft arranged at right
angles to the rotating member and including
beveled gear connections with the member
whereby the same may be rotated for re-
winding the cables thereon, thus closing the 95
two hinged parts.
2. In combination with a hoisting mecha-
nism, a loading tray including two hinged
parts, transverse cables attached to one side
of the tray at one of their ends, for holding 100
the parts in closed positions, a rotating mem-
ber mounted in bearings at the other side of
the tray about which the cables are wound, a
ratchet movable with the rotating member,
a pawl in engagement therewith for pre- 105
venting rotation of the member, a pull cord
for releasing the pawl from engagement
with the ratchet, thus permitting the two
parts to open, a crank shaft arranged at
right angles to the rotating member and in- 110
eluding beveled gear connections with the
member whereby the same may be rotated
for rewinding the cables thereon, thus clos-
ing the two hinged parts.
3. In a device as set forth, a frame, a shaft 115
journaled in bearing of the frame at the top
thereof, and including a plurality of drums,
hoisting cables connected to two of the
drums, a hoisting tray suspended from the
lower end of the hoisting cables,.a pulling 120
cable wound around one of the drums, by
which the hoisting cables may be wound
upon their drums, a brake lever including a
shoe for engaging the side of one of the
drums, a ratchet movable with the shaft, a 125
pawl in engagement with the ratchet, an op-
erating lever pivoted to the frame, and
cables, one being connected between the op-
erating lever and the pawl, while the other
is connected between the brake lever and the 1300
