facturers). Improvements in and relating to explosion-
motors for cycles.*

Claims.—(1.) The combination with an ordinary bicycle
of the safety type of a motor and its accessories grouped and
fixed within an approximately triangular tubular-steel frame,
said frame being held to the bicycle or main frame by
means of adjustable fastenings so as to distribute the strains,
substantially as described and explained, and illustrated.
(2.) In motor-cycles, fastenings for securing the motor-
frame to the main frame, consisting of ring screw-bolts
(such as 4) on the motor-frame, plates or clamps such as 5,
and wing-nuts such as 6, said fastenings being so placed as to
distribute the strains on the main frame, substantially as
described and explained, and as illustrated. (3.) In motor-
cycles, a casing for the motive parts, in which the side-plates
or cheeks are widened towards the front, said plates being
held to the motor-frame by means of spring clips, substan-
tially as described and explained, and as illustrated in Figs. 1,
2, and 4 of the drawings.

No. 19153.—1st March, 1905.—ALEXANDER GILLIES, of
Terang, Victoria, Australia, Dairyman. Improvements in
pneumatic teat-cups.*

Extracts from Specification.—According to this invention,
within the rigid outer shell 1 is placed an inner rubber
tubular casing 2, which is moulded or cut longitudinally and
parallel with its periphery so as to form a double thin wall,
with an air space or cavity 3 between for approximately
half the circumference, as shown in Figs. 2, 3, and 6. The
cavity extends downwardly to within a short distance of the
base of the casing, and tapers off at the bottom into a pair
of V-shaped ends 4, and forms with the walls an inflatable
bag 5, which resembles as nearly as possible the shape of a
calf’s tongue. Diametrically opposite the upper end of this
tongue or bag 5 the casing is cut or slit longitudinally and
parallel with its periphery, thus forming another cavity 12,
which, however, only extends a very short distance in a
downward direction and is tapered off at its lower end into
two V-shaped legs 13 (Fig. 1) and closed at its upper end
in a manner similar to the above-mentioned tongue, the
whole comprising a small inflatable “gum” 14, the object
of which is to grip the teat and hold same in the proper
position for milking. The inner surfaces of both these
inflatable parts—i.e., “tongue” and “gum”—are ribbed or
roughened as at 15, like a calf’s mouth, so as to enable the
teat to be more securely gripped. The inflatable “gum” 14 is
in permanent direct communication with the atmosphere by
means of a tube 16, which extends through the base of the
casing and is imbedded in the wall thereof for part of its
length.

in place of the claims.]
