pressure, running at 150 revolutions per minute, and Mr. Mc- 
Laren stated that the steam consumption was between 17 and 
18 lbs. per brake horse-power per hour. The engine is of a 
strong, serviceable pattern, and will, no doubt, make its way. 
IV. Dairy Implements. 
TJte Aijlcsbiinj Dairi/ Company^ Lim., showed a "Star" 
Hand Separator (Art. 1482), which differs from most of the hand 
separators in that (1) the driving 
Fig. 14. — "Star" Hand gear is fixed to the top part of 
Separator. the frame of the machine. (2) 
The drum, which is approximately 
spherical in form, is of consider- 
able size and weight. (3) The 
speed arranged for rotating the 
liaudle is much slower than 
usual. 
All the moving parts are very 
well balanced, and although the 
machine may as a consequence 
of (2) and (8) be a little heavier 
in starting, it has for the same 
reason the advantage of main- 
taining its speed for a consider- 
able time, as evidenced in the trial 
made by its taking 15 minutes to 
come to rest : this enables an at- 
tendant to leave the machine for 
a few moments, if necessary, 
either to move or replace cans, 
&c. 
Tlip driving' gear of the machine is 
in the top part of the frame, and con- 
sists of an avranr enient of spur or wheels, wliich, by means of a handle, 
rotates a vertical f-pindlc. This spindle has in its lower end a recess sochet, 
which is lined witli an india-rubber bush; into this socket the upper end of 
the drum spindle is introduced and rotated by the cross-pin in the end of the 
spindle htting into slots or notches in the socket of the top vertical spindle. 
The drum spindle on which the drum is fitted simjily by a cone rests with 
its male centre in the female centre on the screwed spindle. This spindle 
can be lowered and raised l)y the action of a handle and mitre wheels, thereby 
allowing the drum spindle and drum to be tixed in the machine or removed 
therefrom. 
The tendency of the drum spindle when driven will always be to find its 
exact vertical position, and the drum and spindle will rotate like a spinning 
top on its true centre; the upper end of the spindle is allowed to find its 
own position iu the socket of the top spindle by reason of the elastic bush.
