Referring now to the drawingathe numeral |
designates the base or lower carriage frame,
20 which, as shown, preferably comprises) longitudi
nal side members of inverted T-section, ,but,
horizontal middle upper portion l8, from the
ends of which leg portions I9 diverge downward
ly, the lower end portions of the leg portions
turned to be disposed vertically, as at 20, and
respectively united with the inner side S of the
vertical stem ?anges of the inverted T-shaped
side members I of the base or lower carriage
frame, as best shown in Figure 2 of the drawings. 10
Secured on top of.the frame members I6, H,
are a pair of horizontal longitudinally disposed
members 2| of L-shape cross section, and this
super-frame'structure is preferably completed by
the provision of diagonal brace members 22, a 15
pair of which are crossed at one side of the struc
ture, and a single member being provided at the
opposite side thereof, as shown in Figure 1, one
member being omitted at this side to aiford
clearance for pulley and belt to be later de 20
scribed.
,
obviously, may be of any approved or desired
form. Near the ends of the frame the side mem
bers I are cross-connected by plate members 2.
Supported on the above described super-frame
structure is a housing 23 for an ice receiving
hopper and a co-operating means for crushing
25/ These members are preferably united by welding
the ice received in the hopper. As shown, this
housing 23 comprises a pair of side plates 24, 25,
the lower edge portions of which rest on the
portions I8 of the frame members I6, I1, and their
process, as are the various other structural mem
bers hereinafter described, unless otherwise
speci?cally stated.
'
As shown, the base or lower carriage frame is
, mounted on conventional ?anged wheels 3 to
obviously travel on rails, as will be more fully
hereinafter described. However, for portability,
adjacent outer face portions are welded to the
abutting inner faces of the vertical ?anges of
said horizontal top’ frame members 2|. The
inner upper marginal portions of the plates 24,
the frame may be mounted on other types of
25, are connected by a right angular plate 26 hav
wheels or rollers, depending upon the particular
location and manner in which the apparatus is
ing its vertical marginal portions ?anged, as at
used.
A suitable braking mechanism is provided for
holding the machine in position while in use. As
shown, a transverse brake beam 4 is slidable
40 longitudinlly of the base or lower carriage frame
on supporting brackets 5 secured on the under
sides of the‘ side members I of the frame.
Welded to the ends of the beam 4 are arcuate
brackets 6 which are L-shape in cross section and
45 carry brake shoes ‘I, preferablyv wooden blocks,
and provided with linings 8 of rubber or suitable
?brous material, to engage the tread surfaces of
the adjacent wheels 3.
Welded tothe middle
under portion of the beam 4 is an operating bar
50 or rod 9, the outer end portion of the bar or rod
being screw-threaded and projected slidably
through an aperture provided therefor in the
vertical ?ange of an L-shape cross frame mema
.ber I0 secured to_the under sides of the side
55 ‘members | of the base or lower carriage frame
(see Figures 1, 2, 6 and '7).
This bar or rod is
normally urged inwardly by a spring I I, inter
posed between the vertical ?ange of the cross
member I0 and a collar I2 ?xed on the bar or
60 rod, thereby releasing the brake shoes 1 from
engagement with'the wheels 3. 0n the project-'
ing screw-threaded outer end portion of the bar
or rod 9 is a correspondingly internally screw
threaded hub portion l3 of a crank member I4,
65 having a handle portion I5. By turning the
crank in one, direction the bar or rod 9 is drawn
outwardly, thereby clamping the brake shoes 1
against the correlated wheels 3, and in the op
posite direction the bar or rod is permitted move
70 ment inwardly under the reaction of the spring
ll, whereby the brake shoes are released from
engagement with the wheels.
Near one end of the base or lower carriage
frame is a super-frame structure comprising the
; two opposed upright frame members I6, I‘I,
21, and its horizontal marginal portions likewise
?anged, as at 28, said ?anged portions overlap
ping the adjacent outer faces of the side plates
24, 25, and being welded thereto.
Within the housing 23, adjacent said plate 26,
l
is a supplemental plate 29, a portion. of which is
arcuate, as at 30, and substantially concentric
with a cylindrical ice crushing element to be
later described, said supplemental plate 29 hav
ing its opposite side marglnal'portions ?anged,
as at 3|, and welded or otherwise secured to the 45
inner faces of the respective side plates 24, 25.
An inclined hopper plate 32 has its upper mar
ginal portion 33, rolled to ?t supportingly on a
transverse rod 34 which is secured at its opposite
ends in apertures provided therefor in said side
plates 24, 25 (see Figure 10). The lower mar
ginal portion of this hopper plate 32, as shown,
rests on the upper portion of the inclined bottom
plate 35 of a chute 36 which conveys the crushed
ice to an impelling device to be later described. 55
The plate 35 has its upper marginal portion
rolled, as at 31, in a manner similar to the end
portion 33 of said hopper plate 32, and it is sup
ported on a transverse rod 38, similar to the rod
34.
Near the lower end of the hopper plate 32, a
grate element 39 is provided (see Figures 10 and
12), this element in effect comprising a series
of spaced lugs 40 which hold the pieces of ice
received in the hopper 4|, and with which the
crushing element, now to be described, co-oper
ates in its operation.
Mounted on a shaft 42, having antifriction
bearings 43 provided therefor on said housing
plates 24, 25, is a cylindrical member 44, the hub 70
portion 45 of which is keyed, as at 46, to said
shaft 42 (see Figure 10) . On the circumference
of the cylinder 44 are a series of substantially
tangential spikes or sharp pointed studs 41
which, during the rotation of the cylinder, pass 75
2,136,214
through the spaces between the lugs 49 of the
grate element 39. ‘The spikes or studs 41 may
be provided in any suitable number and relative
arrangement upon the circumference of the cyl
inder 44. For practical purposes and considering
the high speed at which the cylinder 44 is
rotated in operation, nine of the spikes 41 are

recessed portions, is welded or otherwise ?xedly '
secured to the margins of said blades or vanes,
thereby reinforcing the rotor structure.
On opposite sides of the cylindrical housing~
are-supporting members 14, the upper portions or
which are arcuate and secured to the respective
side wall plates 6|, 62, preferably by welding, al
though, of course, other approved means of at~ 10

and 3).
The super-frame 18, which is located near the
end of the base or lower carriage frame I, sup
ports a conventional anti-friction bearing 88 for 25
the outer end portion of the shaft 61 of the im
pelling device. Secured on the shaft 61 is a pul

pulley 83 on the shaft 84 of a motor (preferably
electric) 85. As shown, the motor 85 is covered 30
by a continuation of the hereinbefore described
hood 51 covering the motor 56. Preferably, the
able and interchangeable to secure different speed

through which the crushed ice is delivered to the
housing from the chute 36, the delivery end of
said chute being supported on a substantially
U-sh-aped reinforcing member 65 secured on the
outer face of said wall plate 6|, said member 65
being preferably formed from a length of angle
iron, as shown in Figures 1 and 9.
The opposite wall plate 62 is provided with

adaptation of the invention is of the reversible
type, or, in other words, is adapted to rotate the
shaft 84 in opposite directions, and, accordingly,
the rotor of the impelling device is actuated and
the crushed ice delivered from the device through
either of the discharge tubes 60, at will, .and de
pending upon the side of the machine at which
the car to be iced is located.
To close the tube 60 not used a hollow cy
10 lindrical closure member 99 is preferably pro
vided, as shown in Figures'3 and 8. As shown,
this member 99 is closed at its inner end, as at
I00, and it is provided with an external annular
collar IOI engaging the end of the tube 60 to limit
15 the inserted position of the closure, and the
closure being releasably held in place by hook ele
ments I02 hingedly. attached to the tube 60 and
engaging studs I03 on the closure member. The
hook elements I02 also hold a conveyor tube, to.
20 be presently described, on the discharge tube 60
being used and through which the crushed ice
is delivered to the car.
The preferred conveyor tube is illustrated in de
tail in Figures 13 and'14 of the drawings and its
25 application to the crushed ice impelling device of
the apparatus of the present invention isshown in
a practical adaptation in Figure 15. As shown,
the ‘conveyor. tube comprises a coupling 'sleeve
member I04 to ?t over the discharge tube 60 of
30 the impelling'device, said sleeve member having
the end portion of a metal tube section I05 ?tted
over its reducedouter end portion (see Figure 13),
the parts being held together by a stud member
I06 on opposite sides in diametrical relation. The
stud members I06 are projected su?iciently to be
engaged .by the hook elements I02 whereby the
conveyor tube is detachably held on the discharge
tube 60 of the impelling device.
Fitted telescopically withboth longitudinal and
conventionally, is located on the trackway I I6
on the platform III, by which arrangement the
car to be iced may be placed at any position along
side of the platform on the railway track I I3 and
the icing apparatus brought into working position
with respect to the car instead of having to lo
cate or "spot" the car with respect to the ap
paratus.
_
At an elevation above the platform III and in
parallelv alinement over the trackway H6 is a 10
longitudinal ice supply trough II‘! in the bottom
of which are a series of outlet hoppers II8, ob
viously closed normally by trapdoors or releasable
closures (not shown), under one of which the ice
receiving hopper ll of the icing apparatus is posi 16
tioned selectively and conveniently for the icing
of the car as positioned at the side of the plat
form III. The ice crushing and impelling ma
chine is held in position by applying the herein
before described brake device to the wheels 3.
20
{It is to be here noted that the rotor of the
crushed ice impeller is rotated at a high speed in
operation, and the crushed ice as it is delivered
into the housing 59 through the central side open
ing 64 tends to drop immediately to the bottom 25
of the housing, anyway into the path of the rotor
blades or vanes ‘II which strike the pieces of ice
with great vforcerwhereby the ice is knocked or
batted, with practically the same effect as a ball
or missile when struck by a bat or the like, rather 30
than by slinging or throwing effect from a centrif
ugal or other mechanical similarly effective,
agency or by compressed air or a blast of air from
a fan.
,
It has been found by actual experimentation
and practical use that an._impelling device of the
character illustrated and herein described drives
the pieces of crushed ice with great force and
momentum through the conveyor tube and to a
rotative movement on the metal tube section I05 _ considerable distance from the discharge nozzle
is a second metal tube section I0'I on the outer of the tube. In use, under ordinary conditions, 40
end portion of which is fitted a ?exible tube, pref
and particularly from a platform as illustrated in
erably of the'character of rubber hose, said ?exi
ble tube, designated by the numeral I08, being

from the discharge nozzle IIO the pieces of ice
are,,by manual manipulation of the nozzle, de
livered to all parts of the space in the car above
clamping bands I09, as conventionally shown in
Figure 13.

'
At the outer end of the ?exible tube I00 is a
metal nozzle member or discharge tube II 0, the
outer end portion of which is turned at a slight
angle, preferably sixty (60°) degrees or approxi
mately so, for practical use.
A practical arrangement of a loading platform
alongside of which is a railway track and having
thereon a trackway for the ice crushing and im
pelling machine and overhead means for sup
plying ice to the machine, is illustrated more or
less conventionally and schematically. As shown,
the platform III is elevated to approximately
, the level of the bottom of the ordinary refrigerator
r freight car and in co-operative relation to which
a'car, designated by the numeral I I2, is positioned
on the railway track II3. A portion of the car,
as illustrated, is broken away and shown in sec
tion, a load of crated produce Ill, for example,
lettuce or other garden or farm vegetables, being
gown, and on top of which the crushed ice, as in
cated by the numeral H5, is being distributed
from the nozzle IIO of the conveyor tube which
70 in use is projected into the car through the side
door opening and is manipulated by an operator
who stands on a ladder or .other suitable support
(not shown).

car, and with evenness of distribution and with
rapidity. It may be also here noted that an im
pelleroi the character of that of the present in
50
vention drives the pieces of ice to an elevation a
considerable distance above the discharge tube 60,
for example, it has been found in actual prac
tice that the driven ice is easily lifted twenty or
more feet from the discharge tube 60. Hence, 65
the impeller may be located close to the ground, in
some cases, instead of upon a raised platform, and‘
top icing of cars accomplished by use of the ap
paratus at that lower position with facility and
satisfactory results. So, too, in such cases, the
machine may be mounted on ground wheels of
any approved character for portability instead of
?anged wheels for track rails as shown in the
drawings. This being obvious speci?c details are
not illustrated in the drawings.
65
While‘ an air blast from a fan alone will not
impel the crushed ice to any appreciable distance.
the blast created by the rotating blades or vanes
of the rotor naturally assists to some degree the 70
momentum of the forcibly knocked or batted
pieces of ice. Furthermore, the pieces of ice
entering the impelling device are immediately
