Report on the Trials of Implements at Cardiff. 
frames in the ordinary way, and project from the periphery of this wire- 
cylinder. The concave is of the usual construction, with longitudinal flat 
bars, 2i inches from centre to centre, and curved iron-wires, \ inch diameter 
and 4 inch from centre to centre. The shakers are carried on rocking- 
links at the delivery ends, and on a crank-shaft at their inner ends. This 
arrangement does not secure an efficient jerk throughout the length of the 
shakers. A double caving-riddle is employed, the two parts of which move 
independently. The upper riddle has large oval holes, 1? to If inch diameter; 
the lower riddle is one of Humphries' make. The bevel-wheel employed 
to drive the screen is noisy; the bearing being rather far from the wheel, 
the shaft springs a little in working. The corn is delivered on the left side, 
the cavings at the back, and the chaff is delivered on the ground under the 
hind wheels, a \)zxl not easy to get at for removing it. The frame, of oak, is 
well constructed, but the position of the screen-case is objectionable ; it projects 
over the left-hand fore wheel, and is thus liable to be damaged in travelling. 
Special means are adopted to prevent any such injury to the corn elevator case. 
It is attached to the outside of the frame by bolts working in slots, and by 
means of a long-handled lever it can be raised 9 inches. Thus, when at work, 
the bottom of the case is only 7 inches, but when travelling it is 16 inches 
above the ground. This is a low-priced machine, which did its work very 
fairly. 
4985. P. and II. P. Gihhons. — Three belts on the left, two of them from the 
drum-shaft, one being op])Osite to the engine-belt. Three belts on the right, 
Two of which are from the drum-shaft on opposite sides, and balance each 
other. Three pairs of bevel-wheels are employed to drive respectively one of 
Penney's screens, the fans beneath the frame, and a long himmieller placed out- 
side the frame. These bevel-gearings were rather noisy in working, and are 
not so well adapted as friction-belts for use in a portable machine. The corn 
is delivered on the right side, the screen being placed over the fore-wheel; 
chaff is blown out on the left side, the fans being placed near the ground, and 
heliind the hind-wheels. We have here a machine in which the elevator, 
hummeller, screen, and fan-case, are all placed outside the main frame. By 
this means ample room is obtained for the working parts, so that there can be 
no fear of clogging up when the grain is in bad condition. We think, how- 
ever, this advantage is counterbalanced by the inconvenient width of the 
machine ; the parts projecting over the wheels would be liable to injury in 
travelling. Only four shaker-boxes are used for the straw ; two of these are on 
a crank-shaft at their delivery end, and the other two on a crank-shaft at 
their inner end, the other ends of each box are carried on rocking links. The 
feeding of this machine was well done. The feeder stood a little on one 
side of the mouth of the drum, and did not take the sheaf into his hands, 
but had it placed on the floor in front; he then spread it a little, and 
pushed it along the floor to the drum. He thus, with less exertion, fed with 
more than the usual regularity. 
4228. Holmes and Sons. — In this and the following machine the winnower 
that separates the chaff from the corn is placed at the top of the machine 
instead of under it ; the drum, and other heavy working parts, are thus brought 
much closer to the ground, an arrangement which ensures steadiness in work- 
ing. There are two belts on the left side ; one of them, from the drum-shaft 
placed opposite to the engine-belt, is bent at a right angle round two friction- 
pulleys, to convey ])Ower to the fans, which, by a cross blast, blow the chafif 
into bags placed on the right side. There are three belts on the right, and a 
short belt at the top of the machine. The construction of the machine is similar 
to that of the non-finishing machine. No. 4229, in Class 111 (see Fig. 17, p. 430). 
The corn and chaff, after falling through the caving riddle, are together 
raised by an elevator furnished witli cups of an extra size. The capes, which 
in most machines are delivered into a basket placed upon the ground, are here
