the winch as the elevating-chain 20 is wound
thereon by the manipulation of the cranks 18.
The chain 20 is provided at its end with a hook
21, as usual.
5 In addition to the winch-rail 12 the boom 5
is equipped with a truck-rail 22, extending
along one side face of the boom at a point
above the lower edge thereof. This truck-
rail 22 instead of terminating at the ends of
1o the boom is provided at one end with a curved
extension or switch 23, the end of which alines
with and is designed to slide freely upon the
flange of the stringer-rail 9. The truck-rail
22 is designed to support a wheeled truck 24,
15 from one side of which is suspended a hanger
25, equipped with grappling mechanism de-
signed to effect the transfer of an ice-can from
the hoisting mechanism to the truck for con-
veyance to the ice-dump or any other desired
20 point. The grappling mechanism includes a
grappling-hook 26, having a comparatively
long shank 27, bifurcated at its upper end (see
Fig. 5) and pivotally connected, as indicated
at 28, to one end of a lever 29, fulcrumed, as
25 indicated at 30, upon the angular lower ex-
tremity 31 of the hanger 25. That portion of
the lever 29 which is connected to the hanger
and grappling-hook shank is in the form of a
loop 32, receiving the lower end of the hanger
30 25, as shown. One end of the loop 32-to
wit, that end thereof from which the handle
33 of the lever extends-is designed to abut
against one edge of the hanger 25, as shown
in Fig. 3, to limit the movement of the lever,
35 while the opposite end of the loop is designed
to be engaged by a pivoted catch 31, carried
by the hanger 25 when the handle of the lever
is drawn down to the dotted position in Fig.
3 for the purpose of raising the grappling-
40 hook 26 to effect the transfer of the ice-can
from the hoisting mechanism to the truck.
When it is desired to convey the cans from
one of the freezing-tanks, the boom is shifted
along the stringers until it arrives above the
45 tank. The winch is then shifted along the
boom to a position above one of the ice-cans,
usually the one at the left-hand end of the
tank. A can-jack 35 is then attached to the
can, as shown in Fig. 3, and the hook 21 of
50 the winch chain or cable is drawn down and
passed through the ring 36 of the jack, care
being taken to have the hook 21 open toward
the front-that is to say, toward that side of
the boom at which the truck is supported.
55 The winch is then operated to hoist the ice-
can from the freezing-tank, and when it has
reached the proper height the truck 24 is
shifted along the truck-rail until the grap-
pling-hook arrives in position to engage the
6o ring 36 of the can-jack, it being understood
that the cranks of the winch are brought to
rest in a vertical position in order to prevent
interference with the mechanism suspendedfrom the truck when the latter is shifted to
its engaging position. The grappling-hook 65
is now passed into the ring 36 from the side
opposite the hook 21, and the lever 29 is then
swung to the dotted position in Fig. 3 for the
purpose of lifting the can, and thereby de-
taching the ring 36 from the hook 21 of the 70
hoisting mechanism. The elevation of the
short end of the lever 29 will cause it to snap
under the catch 34, and the grappling-hook
will thus be prevented from moving down-
ward, since this movement must necessarily 75
be accompanied by the movement of the lever
29, which is locked against movement by the
catch 34. The described manipulation of the
parts will have effected the transfer of the
can from the hoisting mechanism to the truck, 8o
and the latter may now be shifted along the
truck-rail and around the deflected end or
switch 23 thereof to the stringer-rail 9, whence
the can may be conveyed to any desired por-
tion of a track or rail system, including the 85
stringer - rail, as an element thereof. The
usual destination of the ice-can is the ice-
dump, (shown conventionally in Fig. 1 at 37,)
and while this dump is shown below one of
the stringer-rails it may be remarked that its .90
usual location is at a point remote from the
freezing-tanks and under a rail to which the
truck is transferred from the stringer-rail
through the medium of intermediate rails and
switches. The point of delivery, however, is 95
entirely immaterial, since the present inven-
tion is concerned particularly with the con-
struction and arrangement of the boom, pro-
vided with the switch 23, adjustable there-
with and equipped in a novel manner with 1 oc
hoisting and conveying mechanism of novel
and advantageous construction.
It is thought that from the foregoing the
construction, operation, and many advan-
tages of my ice-conveying apparatus will be 105
clearly comprehended; but while the present
embodiment of the invention appears at this
time to be preferable I desire to reserve the
right to effect such changes, modifications,
and variations of the illustrated structure as n1o
may fall fairly within the scope of the pro-
tection prayed.
What I claim is-
1. In an apparatus of the class described, the
combination with stringer-rails, and a boom 115
mounted to travel thereon, of a truck-rail
movable with the boom and having a lat-
erally-deflected end overlapping one of the
stringer-rails and constituting a switch.
2. In an apparatus of the class described, the 120
combination with stringer-rails, of a wheeled
boom mounted to travel thereon, and a truck-
rail rigid with the boom and having one end
curved and disposed over one of the stringer-
rails to constitute a traveling switch. 125
3. In an apparatus of the class described, the
