Implement Show at Leicester. 
Class II. 
The best application of Steam Power adapted for Occupations of Moderate Size. 
In tliis class were tried four roundabout systems, and two direct acting 
systems. 
Tiie deciding trials took place on Saturday, July 11th, in a field of about 
12 acres, previously divided into six ^wrtions. 
The competitors were arranged as follows : — 
Lot 1, Aveling and Porter] 
Lot 2, J. and F. Howard I Roundabout. 
Lot 3, Tasker and Sons ) 
Lot 4, Fowler, with clip-drum and travelling disc-anchor. Direct. 
Ljot 5, Edward Hayes, Roundabout. 
Lot (>, Fowler, with double drum engine and travelling disc-anchor. Direct. 
On Friday night the above were ordered to place themselves in a field about 
a quarter of a mile from the scene of action. 
The en2;ines and tackle were drawn up side by side. The different sets 
were started so as to work clear of each other. The time of travelling to the 
field, with all particulars as to the mode of progression, whether by horse- 
power or traction; the time occupied after reaching the field in preparing for 
■work ; the time occupied in actual work ; and the nature of the work ascer- 
tained by numerous observations, and by actual weight of soil moved, were 
all data by which we were enabled to arrive at a decision as to the merits of 
the different systems, which systems we will now describe : — 
ioi 1. — Aveling and Porter, who by their excellent traction-engino 
work. Fowler's implement and Fowler's winding-drums, exhibited 
a combination, consisting of a 10-horse- power traction-engine, £ 
No, 59G9, price 420 
Working Fowler and Go's roundabout apparatus, comprising doiible- 
drum windlass, cultivator, porters, snatch-blocks, &c. (5067) .. .. 250 
670 
If with eight of Aveling's travelling-porters, in lieu of ordinary porters, then 
181. extra. 
The windlass consists of a strong axle, supported upon carrying or bearing 
wheels ; on this axle the two drums run loosely. 
The drums are furnished with spur-wheels at their outer edges, into which 
gear at all times two pinions (also loose) upon the driving shaft above. 
Motion is communicated to this shaft from the steam engine by means of 
another shaft with universal joints, which allows for a certain amount of 
irregularity in the adjustment of the windlass relative to the engine. On the 
top shaft is a long sliding clutch, which can be put into gear so as to drive the 
pillion of tiiu one drum or the other. The tension upon the outgoing rope 
is regulated by an ordinary break. The engine must be stojiped in order 
to reverse the drums. The engine named "Leicester," made by the exhibitors, 
who have devoted much attention to traction engines, appeared to be excellently 
manufactured, and to possess very great steering facilities, there being a 
leading-wheel in front of the ordinary steering wheels. The whole steering 
"was readily managed by a young lad. 
The time occupied in reaching the field was eight minutes; the time of 
getting to work after the field was reached was forty minutes. The engine 
drew after it a waggon carrying the snatch-blocks, anchors, &c. ; and also 
drew a train composed of the windlass, the cultivating implements, and the 
porters. 
The implement used was a 5-tine bevel beam cultivator on the balance 
principle.
