Fig. 36. — Sams' s Patent Disc Seed-discltarger, No. 888. 
The Sams's Patent Disc Seed Discharger exhibited by Mei^srs. B. lieida 
Co., of the Bon-Accord Works, Aberdeen, shown in the accompanying cut, i 
a very simple and efficient substitute for the cups and brushes commonly use 
in drills and seed distributors. The disc is waved, so that in each revolutio 
four deliveries of seed are made into the hole beneath it; the size of thes 
holes is regulated by a sliding bar with similar holes adjusted beneath th 
seed-box by means of a handle in the middle of the machine. The broadcas 
sowing machine in which these discs were exhibited has other merits in i 
construction, and was tested on a wet and muddy part of the Show-ya 
where it delivered its seed very evenly, and worked to the satisfaction of th_. 
Judges. The seed-box is 12 feet long, made in one piece and very strong ; it 
is hung between 2 wheels of 4 feet 6 inches diameter. These wheels revolve 
upon an axle 13 feet 6 inches long ; by means of a ratchet and paul this axle 
only revolves as the machine advances, so that no seed drops oixt in turning 
at the headlands; the seed-box being beneath this shaft is nearer the ground 
than in most machines with smaller wheels, hence it can be \ised in windy 
weather, and is yet very light in draught. A quick stepping horse will sow 
18 to 20 acres a day. Upon the middle of the carriage-shaft a spur-wheel is 
keyed, and works by double gearing into a .spur-wheel ujion the disc-shaft 
that revolves in the bottom of the seed-box. The intermediate spur pinions 
can be ]iut in and out of gear by means of a lever handle in the centre of the 
box. When working \\\) or down hill the seed is sown at the same pace 
without any adjustment. For travelling along a road the two land-wheels are 
removed from tiio long axle on to a short cross axle in the middle of the box, 
and the shafts are removed from the centre to one end of.the box. Two size 
of discs are used, a large one for grain and .small seeds, a small one for l)eans 
])eas, and other large seeds. The price of the machine to sow 12 feet, wit 
road carriage, is 1 4?. 10s.
