Improvements in the Construction of Ice-breaking Machines.
I, CHARLES EMERSON BARTON of Providence Works, Eleanor Street Great
Grimsby, in the County of Lincoln, Fingineer do hereby declare the nature of this
invention and in what manner the sanie is to be performed, to be particularly
described and ascertained in and by the following statement :-
-
My invention relates to improvements in the construction of ice breaking machines,
and is based upon the Specification of Letters Patent granted to me No. 1520
A.D. 1870.
The objects of my present invention are to render the whole apparatus more
durable, and also affording greater facilities in obtaining access to the interior, for
repairs and the like.
In order that my invention may be the better understood I have appended the
accompanying sheet of drawings in which Figure 1 represents a vertical sectional
elevation, and Figure 2 a reverse elevational view of the device, the latter being
shewn without the hopper or shoot.
In carrying my invention into effect, I employ a spiked drum B, suspended by a
transverse shaft C, within a casing A which is held together by bolts A¹ and the like
fitting into bolts holes A" upon suitable flanges A". To the casing A is attached
fixed spikes a that engage with the spikes & upon the drum B sufficiently for the
purpose of breaking the ice, the crude blocks or lumps being fed into the hopper D.
Below the drum B, and arranged to work together upon the same horizontal axial
line, I provide two smaller spiked drums E, and E', and I also form the sides of the
casing A so as to provide a throat or rectangular delivery I, in which I place a guide
plate G, pivotted at g for diverting the crushed ice to either side of the centro line
as may be desired, this being accomplished by moving the handle or lever H,
Figure 2.
have shewn by the dotted outline e a spur wheel keyed or attached to the
shaft C, and two pinions d' gearing together, and either of these may be made to
engage with the teeth of, or gear with the spur wheel c directly, or by means of an
intermediate geared wheel e upon a stud f, and a pulley or rigger may be attached to
the shaft or boss of any meniber of the train of gearing c d d' and e for the purpose
of transmitting motive power thereto, or a handle or cranked lever may be similarly
attached for the employment of manual power. I do not however confine myself to
the drums and gearing as hereinbefore described, but refer ospecially to the improve-
ments in the construction of the casing A, and the mounting and housing of the
bearings for the various spindles or shafts.
The casting forming the casing A is made so as to be divisible vertically at the
junction of the flanges c¹ and e¹ and the side frame pieces or cheeks are similarly
divided, so that square brass bearings, provided with flanges J, K and K¹ may be
fitted into suitable housings formed in the side frame pieces before mentioned. By
means of this arrangement the brass bearings may be removed, or set up to
compensate wear without rendering it necessary to take the whole machine to
pieces.
The flanged brasses K K' forming bearings for the transverse shafts or spindles of
the spiked rollers E E¹, may, if necessary he fitted into an horizontal slot, and set
screws or an equivalent device may be employed for setting the rollers together, or
withdrawing them so that the spikes may engage to a greater or less extent as may
be desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim
;-
T
heasking marking the emploxinent of side frome pieces that are

page_text: separated at the axial lines of the various bearings, and retained together by means of
flanges A, bolts and the like A', substantially as herein described and shewn by
the appended drawings.
Second. In an ice breaking machine with divided side frame pieces as referred to
in the preceding claim the employment of square flanged brasses, fitting into suitable
housings in said frames, with or without adjusting devices, substantially as herein
described and shewn by the appended drawing.
