tributor itself, of which eight, nine, ten, or more, can be fitted 
into the bottom of the seed box ; the framework consists of two 
moulded castings, which are bolted together, and form the 
chamber (b), in which is a saucer-shaped distributor (c) with 
ribs ; this, keyed on a main shaft revolving vertically, delivers 
the seed at the outlet (d) into the funnels and coulters to the 
ground. The outlet at D is controlled by an adjustable partition 
(e), which is connected at the extremity (a) with a coupling 
rod, at the end of which is a pointer, which, when set by the 
gradations on the dial, correctly indicates the quantity being 
sown per acre. The construction of one manure-box (Fig. 20) 
will serve as a sample of the whole. A square frame (f) is 
screwed into the bottom of the manure-box, below which runs 
a steel shaft, carrying a small bevel wheel for each distributor ;

Chadborn and CahlwelVs Excelsior Drill, No. 2331. 
(h) is a large feed-wheel, which revolves into the bottom of the 
frame (f), and gears into the small bevel wheel mentioned, from 
which it receives its horizontal rotary movement. The scrape 
wheel (j), which is carried by the feed wheel (h), and by their 
combined rotary motion, i.e., the scrape wheel, revolving with 
and upon the feed wheel, take hold of and force every particle of 
the manure, be it dry or sticky, through the opening controlled 
by the gate (g) down into the tubes, and through the coulters 
into the ground. The arm of the gate (g. Fig. 20) is at the 
point (g 1) connected with a coupling-rod, which is, like the 
seed-box in front, provided with a dial and pointer, and the 
opening at G in each of the distributors being adjusted to drill 
any quantity from 1 cwt. upwards per acre as may be needed. 
There is also a simple arrangement of shut-off slides, which can 
be used at will. They claim as an important feature in this drill, 
that its patent " spring coulter " effectually overcomes any diffi-
