Claims.--(1.) The improved vice, comprising the com-
bination with a spindle, extending loosely in bearings beneath

No. 23102.--6th July, 1907.--AKTIESELSKABET BUR-
MEISTER AND WAINS MASKIN-OG SKIBSBYGGGERI, of No. 9
Overgaden neden Vandet, Copenhagen, Denmark, Manu-
facturing Company. Improvements in the method of avoid-
ing formation of rust in tinned-iron tanks or vessels.

Claim.--A method of preventing formation of rust in tinned-
iron tanks or vessels for storing or transporting milk and
other liquids, characterized by tinned or untinned metal or
alloy which is more electro-positive than iron, being arranged
on the inside of the tinned tank, for instance, in recesses of
suitable size, whereby the electric current generated by the
simultaneous action of the liquid coming into contact through
pores in the layer of tin with the two metals, the iron and
the more electro-positive metal, prevents oxygen from being
taken up by the iron, or at least considerably impedes it.

No. 23104.--9th July, 1907.--HARRY REYNOLDS, of Christ-
church, New Zealand, Watchmaker. An improved race-
starting machine.

Claims.--(1.) The improved race-starting machine, com-
prising an upwardly and forwardly inclined rod on each
side of the track, a spring-controlled pulley on the top end of
each rod, a collar slidably mounted on each rod, a rope kept
normally wound on each pulley by the action of the spring,
and having its free end fastened to the collar on the respective
rod, a tape or barrier extending across between the two
collars, and means whereby the collars may be retained at
the bottom ends of the rods and for releasing them simul-
taneously, substantially as specified. (2.) In race-starting
machines, in combination, an upwardly and forwardly in-
clined rod on each side of the track, a collar slidably mounted
on each rod, a cross-pin on each collar, a pivoted hook-lever
on each side of the track adapted to engage with the pin on
the collar when the collar is at the lower end of the rod, a
pivoted hand-lever connected to the hook-levers on both
sides of the track, a tape or barrier extending across the track
and fastened to the collars, a spring-controlled pulley mounted
on the upper end of each inclined rod, and a rope kept nor-
mally wound upon each pulley and fastened to the collar
on the respective rod, substantially as specified. (3.) In
race-starting machines, a tape or barrier made up of a num-
ber of sections joined end to end and connected together

jected to a strain, substantially as and for the purpose specified.
(4.) The improved race-starting machine, substantially as
described and explained, and as illustrated in the drawings.

No. 23108.--10th July, 1907.--THOMAS L. SMITH, of 134
Tenth Street, Milwaukee, Wisconsin, United States of America,
Engineer. Improvements in and connected with rotary mix-
ing-machines.

Claims.--(l.) In a rotary mixing-machine, providing with-
in the mixing receptacle one or more oblique deflecting sur-
faces, the bounding edges of which are in close contact with
or merge into the internal surfaces of the receptacle, the de-
flecting surfaces being also of such a nature that they im-
part a crosswise movement to the material to be mixed, in
addition to the usual rising and falling motion derived from
the rotation of the receptacle. (2.) In a rotary mixing-
machine of the character described, and having a discharge-
trough, adapting the latter to be moved into or out of the
receptacle as required, and in such a manner that the trough
in either position is always so inclined as to allow the material
to automatically drain off, and so that the action of gravity
tends to maintain the trough in the position in which it is
set. (3.) In a rotary mixing-machine of the character de-
scribed, and having a discharge-trough, the combination there-
with of a hopper fitted with a gate, substantially as and for the
purpose set forth. (4.) In a rotary mixing-machine of the
character described, deflecting surfaces within the mixing re-
ceptacle, substantially as described and illustrated by the
several figures of the drawings. (5.) In a rotary mixing-
machine of the character described, means for discharging the
mixed material, substantially as described and as illustrated
by Figs. 1, 2, 6, and 7 of the drawings. (6.) The improved

therein that the receptacle is mounted on rollers on a swing-
ing frame, so that it can be rotated for mixing and tilted to
discharge its contents. (3.) A machine as claimed in claim 2,
characterized therein that the frame is weighted to counter-
balance the weight of the receptacle. (4.) A machine as
claimed in claim 1, characterized therein that the blades in
the receptacle are mounted on brackets so as to stand away
from the surface of the receptacle, and that the latter is pro-
vided inside with renewable liners and outside with drip-
