Report on the Trials of Implements at Taunton. 
Another adjustment for altering the pitch or angle of the teeth with t 
ground is made at o by means of a pair of serrated discs. 
The carrying-wheels of this rake are 48 inches in diameter, the spok 
and tires are of wrought iron ; the spokes are half-round section-bent, as sho^ 
in the drawing, to form half of one spoke and the inner part of the rim of t 
wheel in one piece. These teeth, as in the other rakes bj' these makers, wo 
in couples.

Self-acting Sorse-ralce, No. 1037. 
Fig. 35 illustrates the same makers' plan of trussing the axle, which, in 
great measure, obviates the objection to applying a seat, namely, the liabilit 
of the axle to become deflected by the weight of the driver being jJaced on! 
upon the middle part of the axle, and thus causing disarrangement in varioi 
parts. R shows the truss-rods ; k the seat-irons. It will be noticed thj 
both these are made to clasp the axle by clips, and are held firm by double sei 
screws. 
The Second Prize was given to rSo. 2774, manufactured b 
Haughton and Thompson. It has a very simple arrangemen 
for self-action, but the Judges did not consider the shape o 
the tooth so good as in the First Prize rake, neither was its per 
formance so satisfactory. 
Haughton and Thompson's Self-acting Uorse-rake, Ko. 2774^. — The accom 
panying sketch represents the self-acting horse-rake, which took the Secom 
Prize, by Messrs. Haughton and Thompson. It is 9 feet wide, a is the frjmi 
of the rake and the support of the driver's-seat ; B the travelling-wliecl o 
wrought iron, 4 feet high; d the tooth, showing the particular shape, made o 
steel, and working upon the pivot e. The spur-wheel k is fastened near tbi 
centre of the revolving axle, geared into an intermediate wheel, w, which ala 
gears in a third wheel, o, combined with the ratchet, which is partly coverec 
by a hollow crank-disc, i, within which the pawl works, and partly overlap 
the ratchet-wheel, p is a connecting-rod coupling the disco with the rocking- 
frame of the rake gfh. In working the rake, the pressure of the foot Iroir 
the person, when riding, upon the stirrup t, or, when walking, upon the back- 
lever V, by hand, vibrating on the stud u, engages the pawl with the ratchet
