PROVISIONAL SPECIFICATION.
Improvements in Separators or a Combined Air Trunk and Expansion
Chamber, with Improvements in the Form and Construction
thereof.
JOIN ROSE, 4, Harolds Avenue, Buckingham Street, Hull, Engineet, do hereby
declare the nature of this invention to be as follows:-
There 18 a vertical an trunk which is turned over at the top in the form of a
bemmichele, which forms the top of the expansion chamber, it is brought straight
down some distance and then tapered either one or both sides to bring it to a
point, the air trunk forms one side There is a valve at the bottom of the
expansion chamber for the discharge of light gram, and outlets in each end for
the au into the side trunks which lead to the fan. A feed hopper is connected
to the vertical an trunk with a feed gate to spreading the giain, or it can be
made with an inlet for the giain

JOHN ROSE, 4, Harolds Avenue, Buckingham Street, Hull, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be pei-
formed, to be particularly described and ascertained in and by the following
statement;-
1
The expansion chamber is formed on one side of the vertical air trunk whilst
the feed hoppe is formed on the other side, the top of the an trunk is brought
over in the form of a semicircle and continued down for a suitable distance, the
bottom of the expansion chamber is brought to a point by tapering one or both
sides to facilitate the discharge through the valve. The feed hopper is mado
with an enclosed passiage into the air tiunk The tail or back end asparation
18 made without a hoppei having only an inlet for the grain.
Refering to the diawing, which is a longitudinal sectional elevation
BB 18 the expansion chambers CC is the valves for the
DD is the outlets for air into the side trunks, 1 is a
is the feed hopper H is the feed gate for spreading
passiage to the air trunk. J is the sieve, K is the
AA is the an trunks
discharge of light grain
side trunk, is the pau,
the grain I is the enclosed

It will thus be seen that grain enters the feed hopper & passing
through the enclosed passage into the air trunk A where it is subject to a curent
of air which lifts out light corn chaff and dust, the light corn 18 deposited at
the bottom of the expansion chamber passing out by the valve C, the good giam
passing along the sieve into the back air trunk where it is treated as before
Having now particularly descubed and ascertained the nature of my said
invention and in what manner the same 18 to be performed I declare what
I claim 18. —
1st The combined a trunk and expansion chamber with the semicircular
top and feed hopper as set forth and described
2nd The combined an tiunk and expansion chamber with the semicircular
top and tapered bottom with valve, as set forth and described.
