page_text: I, CHARLES WILLIAM TANNER of the South Metropolitan Gas Works. 709A Old
Kent Road, in the County of Surrey Chief Foreman of the said Gas Works do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention has for its object the construction of apparatus for breaking coke,
commonly called "coke breakers," in such a manner as to reduce their wear and tear,
and to admit of the various parts when worn being replaced with great facility, while
the quantity of breeze produced by their use is greatly reduced.
In order that the invention may be easily understood drawings are attached hereto
of which the following is a description. Fig. 1 is a part plan and part sectional plan
of the apparatus.
Fig. 2 is a side elevation of it, a part being written in section.
Fig. 3 is an end elevation. Fig. + is a side elevation of the segmental teeth. Fig. 5
is a cross section of the same. Fig. 6 is a transverse section of the segmental teeth,
and Fig. 7 shows the screw, washer and nut for compressing the discs of teeth and
distance pieces into a tightly compacted body. Fig. 8 is a part end and part sectional
view of the cylinder and knives and Fig. 9 is a view of Fig. 8 taken at right angles
to the same. Fig. 10 is a front elevation of one of the knives and Fig. 11 is an end
elevation of it. Fig. 12 is a front elevation of the coke feeder and Fig. 13 is a
transverse section of it. In each of the views similar letters refer to the same parts.
The apparatus consists of a strong frame A Fig. 1. Upon this frame a shaft B
working in suitable bearings a a is mounted and carries a cylinder C Fig. 8, to which
are attached a number of knives D D placed diagonally, or spirally, the knives being
made of steel and shaped so as to enter the straight grooves E E. of the cylinder C,
the knives being secured in position by ring plates F, F, Figs. 8 and 9. Tho frame A
also has inserted in the slots G Fig. 2 suitable bearings H H which carry a shaft J,
the body of which is squaro, and upon which are mounted a number of distance
pieces N Figs. 4 and 5. Upon these distance pieces are mounted by means of studs
or pins the segments LL having teeth M, M. One end of the shaft J is provided
with a fixed collar Fig. 1. The opposite end of the shaft has a screw cut upon it

page_text: and is furnished with a washer Q and nut R. The discs and distance pieces being
placed upon the shaft, alternately, hetween the collar and the screw the whole may be
tightly compressed by screwing up the nut R. Or in case it is desired to remove and
replace any of the toothed segments L L they may, any of them, be reached by
unscrewing the nut R The shaft J complete with the bearings may be removed
by taking out the gap-pieces Z Z. For the purpose of adjusting and keeping the
teeth and knives at a suitable distance from each other a strong coach spring S is
placed as shown in Fig. 1, and caused to press upon the bearings H H either directly,
or indirectly through the intervention of sliding blocks T T, the adjustment being
made by turning the screw U. The frame A is surmounted by a hopper V open at
bottom and at W Fig. 2, the height of this latter opening being regulated by a sliding
door or plate X which is provided with a screw Y 'to retain the said door or plate in
any desired position.
The whole of the different parts of the apparatus being arranged relatively to cach
other as shown in the drawings and motion being imparted to the shaft B, the hopper
may be charged with coke by shovel or other means, when the coke falling upon the
knives D is carried against the teeth M and in its passage between the knives and the
teeth it is cracked or broken and falls into a suitable receptacle below, from whence
it may be removed by any appropriate means. The filling of the hopper by hand
however would in many cases he neither sufficiently continuous or expeditious and a
feeder as shown in Figs. 12 and 13 is therefore provided. This consists of a drum or
cylinder b b mounted upon a shaft c which works in bearings d attached to the top of
the hopper, or placed at any convenient distance above it. The drum is provided with
a number of blades or arms e e and the coko being led to them by a shoot, they, when
made to revolve deliver the coke on to the knives in a constantly regular layer or
stream, and the breaking then takes place as before referred to.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is,
1.-The construction of coke breakers with knives D mounted and arranged upon
a shaft B as herein described and shown on the drawings.
2. The construction of coke breakers with teeth M and distance pieces N mounted
and arranged upon a shaft J and formed as herein described and shown on the
drawings.
3. The spring S applied as herein described and shown on the drawings, and
4. The combination and arrangement of the various parts as herein described and
shown on the drawings.
