[No. 10

termittent admission of air-pressure into the outer chamber
necessitated a considerable amount of power to afterwards
remove it in order to produce the alternate suction. With
this invention, when the suction is in communication with the
inner chamber the small quantity of air admitted into the
“milk-way” merely assists the discharge of the milk which
is flowing from the teat at this time, and does not appreciably
affect the degree of suction, but when the suction is temporarily substantially cut off from the inner chamber the air
admitted at once reduces the degree of suction within the
inner chamber, thus relieving the strain on the teat and allowing the inner lining to distend as before stated. If preferred, instead of using two separate tubes from the respective
passages of the claw to the suction-supply one of said passages
may be joined to the other or placed in communication therewith, and the suction would be connected by a single tube
to the milk-passage, in which case a non-return valve is employed in the other passage to prevent the suction in the outer
chamber being broken.

No. 23328.—21st August, 1907.—FREDERICK RIDLEY
DENNISON, of Oamaru, Otago, New Zealand, Mechanic. An improved spare wheel for motor-cars and the like.*

Extract from Specification.—According to my invention
a rim constructed to carry a pneumatic tire in the ordinary
way is provided with a laterally projecting ring, adapted
to pass into or outside the rim of the defective wheel, or two
rings may be used, one fitting inside and the other outside
the rim, the edge of which thus lies in a groove. The spare
rim is attached to the wheel by any suitable connecting
means, and preferably by hooked bolts engaging the spokes
of the defective wheel, and passing through ears and lugs
integral with or secured to the conical rim.

Engineer. Improvements in extraction apparatus.

Claims.—(1.) An extraction apparatus comprising a vessel,
superposed filter-beds therein dividing the same into compartments, and a common distributing chamber for said
compartments. (2.) An extraction apparatus comprising a
vessel, superposed filter-beds therein dividing the same into
compartments, a common distributing chamber for said
compartments, and inlet seals between the distributing chamber and said compartments. (3.) An extraction apparatus comprising a vessel, superposed filter-beds therein
dividing the same into compartments, a common distributing
chamber for said compartments, and separate outlets for the
filtered liquid. (4.) An extraction apparatus, comprising a substantially liquid-tight vessel, means for inclining
the same, superposed filter-beds dividing said vessel into
compartments, and a common distributing chamber for said
compartments. (5.) An extraction apparatus comprising a substantially liquid-tight vessel, means for inclining
the same, superposed filter-beds dividing said vessel into
compartments, a common distributing chamber for said compartments, and inlet seals between the distributing chamber
and said compartments. (6.) An extraction apparatus
comprising a vessel, a filter-bed therein, an inlet, and an
inlet-seal between said inlet and filter-bed. (7.) An extraction apparatus comprising a substantially liquid-tight vessel,
means for inclining the same, a filter-bed therein, an inlet, and
an inlet-seal between said inlet and filter-bed.

No. 23614.—17th October, 1907.—JAMES RICHARD
MALLYON, of “Otterbourne,” Yass, New South Wales, Australia, Station-manager. An improved apparatus for turning
the leaves of music and other publications.*

Extracts from Specification.—This invention provides an improved apparatus intended primarily for use in turning the
leaves of music. The apparatus is so designed that the
leaves can at a slight touch of the operator’s finger be turned from right to left, and from left to right, with
ease and celerity, and either one at a time or all the leaves
simultaneously. . . . In operation the music-book is
opened at the last sheet to be turned, and it is supported
on the top flange (d) and on the back of the music-rest with
the centre of the book opposite the pivot-pin (g) of the leaf-turning arms (f). The remaining leaves on the right of the
book are secured in the ordinary manner to the music-rest.
The first sheet on the left-hand side and last to be turned
is then secured to the third or lowest turning-arm (f), and the
second and first sheets to be turned are secured to their
respective turning-arms by means of the clips (j). As the
sheets are placed in their respective clips the arms (f) are
turned from the left- to the right-hand side, leaving the first
sheet exposed to view. The turning-arms (f) and consequently their attached sheets are turned in their proper order
by striking the left side of the finger-operating pieces (l) of
the levers (k) one at a time in their order downwards. If
preferred, the leaves may be attached to the turning-arms (f)
in the reverse order—that is to say, the topmost arm may
be secured to the last sheet, and the bottom arm (f) to the
first sheet to be turned. In this case the finger-pieces (l)
would be operated in their order upwards. The sheets can
be returned from the left- to the right-hand side simultaneously
by pressing the right-hand side of the three levers (k) at the
same time, by which means the operator at the end of a verse
of a song is enabled to turn the sheets back to the commencement or first sheet very quickly.

No. 23659.—29th October, 1907.—JAMES MITCHELL YOUNGSON, of Clinton, Otago, New Zealand, Farmer. Improved
coupling-hook.*

Claims.—(1.) A coupling-hook approximately of the shape
of the letter “C,” having a gate swivelled upon its body
portion adapted to pass between the opened ends of the loop,
and a button pivoted upon said gate having ends projecting
beyond the gate and adapted to pass into recesses in the
opposite ends of the loop to retain the gate in position, substantially as specified. (2.) A coupling-hook consisting of the
parts constructed, combined, arranged, and operating substantially as and for the purposes specified, and as illustrated
in the drawings.
