436 Report on the Trials of Implements at Cardiff. 
and consequently was forced wide open in the trial in chief; this was unfor- 
tunate, as the results of the subsequent trial show that this machine is 
capable of doing excellent work. Fig. 17 shows the general arrangement of 
parts. The drum-shaft seen in the centre of the cut is placed lower than 
in most machines ; the cavings are delivered a^t the back ; the corn and chaif 
fall through the caving-riddle upon a ^ne screen that removes small weed 
seeds, and are then together raised on the left side by an elevator, with very 
large cups, to the winnowing ajjparatus upon the top of the frame. The 
chaff, it will be noticed, falls at once into bags, and does not need any 
separate bagging apparatus, as in machines that have the winnowing-bo.x 
under instead of above the frame. The chobs are similarly delivered to the 
drum, and do not need to be raised in a basket, as is commonly done, by ban 
The corn is delivered into sacks on the left side.

2053. Barrows and Stewart. — The frame is made as for a finishing-machine, 
but with the case intended for the rotary screen empty. Three belts are driven 
IVom the right-hand end of the drum-shaft, and the outside strap is placed so 
far from the bearing that there is a tendency to bend the shaft and so work 
unevenly on the bearing. Even in the short time of trial this bearing heated. 
Only four shaker-boxes are used. The deliverj' ends of these are fixed alter- 
nately on two cross-bars ; these bars are carried on wooden spring hangers. The 
inner ends of the shakers are driven in the usual way by a crank-shaft. This 
method does not give sufficient jerking to the straw at the delivery end, con- 
sequently the points in column 29 are low. In the trial the wheels were not 
properly held in position, consequently the machine worked very unsteadily. 
4885. Edward Humphries. — Drum-beaters used with a plain surface. 
Shaker-cranks work in bearings of wood, boiled in oil. The belt on the right- 
hand end of the drum-shaft, driving the white coater, is placed 11 inches (mea- 
sured to the middle of the stra])) from the bearing, which consequently heated 
ill the trial. A double-blast machine.
