preparing flax-waste as cattle-food.*

Claim.—The use of hot air or steam-heated (jacketed)
metallic cylinders such as described, for the purpose described

No. 22909.—29th May, 1907.—MARK DONALDSON, of
Stand 1251, Berea Road, Bezuidenhout Valley, Johannesburg,
Transvaal, Speculator, and WILLIAM GRIFFITH WILLIAMS,
of 36 End Street, Johannesburg aforesaid, Contractor. Im-
provements in totalisator apparatus.*

Claims.—(1.) The improved totalisator apparatus sub-
stantially as described. (2.) In apparatus of the nature
specified, the combination of apparatus for printing tickets
with adjustable “horse” numbers, separate electrically
operated totalling-mechanisms for the several “horse”
numbers, and electrical transmitting-mechanism whereby
upon the printing of a ticket the corresponding “horse”
total is increased by unity. (3.) In apparatus of the nature
specified, the printing-mechanism substantially as described
with reference to Figs. I, II, and V of the drawings. (4.) In
apparatus of the nature specified, the totalling or counting
and indicating mechanism substantially as described with
reference to Figs. XV—XVII of the drawings. (5.) In appa-
ratus of the nature specified, the arrangement of ball floors
divided into compartments, each controlled by an electrical
escapement, and shoots for conveying balls from the escape-
ments to counting-mechanism, the whole of the escapements
for one horse number being grouped together, and there being
where necessary separate shoots and counting-mechanism
for “wins” and “places,” substantially as described with
reference to Figs. IX—XIV of the drawings. (6.) In appa-
ratus of the nature specified, the electrical escapements sub-
stantially as described with reference to Figs. IX and X of
the drawings. (7.) In apparatus of the nature specified, in
combination with electrically operated totalling-devices, an
electrical transmitting-mechanism associated with a “horse”
number printing-wheel, consisting of a drum having one ele-
ment of each of a plurality of electrical contacts, arranged
helically thereon correspondingly with the numbers on the
horse wheel, and means for depressing the wheel and drum
together, whereby upon a “horse” number being printed
the corresponding contact element on the drum is caused to
make connection with its other element and transmit an
impulse to the corresponding totalising-device, substantially
as described with reference to Figs. I and II of the drawings.
(8.) In apparatus of the nature specified and wherein the
tickets are printed by perforation, the arrangement whereby
the tickets are printed in duplicate from continuous webs
and the duplicate is returned within the machine and rerolled,
substantially as described with reference to Figs. III and IV
of the drawings. (9.) In apparatus of the nature specified,
a ticket-printing mechanism, and in combination therewith
an electrically operated device for locking the same, adapted
to be operated from a central station or other distant point,
substantially as described with reference to Fig. II of the
drawings. (10.) In apparatus of the nature indicated, the
device whereby the adjustable printing-wheels are brought
to and kept in register, consisting of V notches in the peri-
pheries of the wheels and V lugs projecting from fixed parts,
substantially as described with reference to Fig. II of the
drawings.

ing. (2.) In combination, an electric trolley-wheel and its pole,
with a drum normally worked by a spring arranged to keep
a light tension on the usual guiding-line, with a lever arranged
to screw over the said drum to a brake-disc, and lifting the
