barns and granaries. The hoist consists of a socket, four square, 
which is let into the ground, and a post that fits into it, and is 
furnished with a movable head for 
meeting the load at any angle. The Fig. 34. — View of Mr. J. W. 
illustration shows the post standing in 
the socket. The head that contains 
the pulley is free to turn upon the 
bolt that passes through the upper 
part of the post. The pulley can be 
fixed to suit the lead of the horse by 
means of the quadrant and pin. A 
single post and block will serve for 
any number of sockets that it may be 
desirable to insert in different parts of 
the yards or buildings. The price, 
bl. bs., includes the gin and a rope, 
and a greater length of post and socket 
than is shown in the illustration. 
No. 2693, Messrs. J. RicJiardson 
and Soil's Seed Dressing Machine for 
hand-power, comprises a blower fitted 
with regulating slides, a riddle with a 
riddling surface 5 feet by 2 feet, and 
two other screens, one of them with 
the same amount of surface, and the 
other smaller and rotary, with an in- 
dependent motion. The seeds are 
fed from the hopper by a fluted roller ; 
the feed, regulated at will by a slide 
on the hopper, falls first upon the 
rotary screen which is hung on chains 
immediately under the blower, and takes off the roughest material 
from the seeds ; the next riddle removes large seeds like goose 
grass, and the lower shaker takes out hair grass, sand, &c. A 
clean sample is thus obtained at one operation. 
No. 2694 is a Potato Sorting Machine by the same exhibitors, 
of great simplicity. It consists of a strong frame, inside of 
which is suspended on chains a shaker containing three riddles. 
The shaker is worked on the rotary principle by means of two 
cranks, one on each side, driven off the main axle by bevel 
wheels. Two of the riddles are changeable to suit the different 
kinds of potatoes. This machine makes three samples of 
potatoes. 
A still simpler machine, for making two samples only, was 
exhibited by Mr. H. Coocli, No. 2307, in which a single riddle 
is hung on chains and agitated by hand.
