crank, which gives a speed of 28-89 to 1 revolution of the road-wheel, or 4 to 1 
foot of circumference, showing an increase of speed of 2-27 to one revolution of 
the road-wheel ; the fingers are 2^ inches apart ; the length of the throw is 2^. 
Fig. 9 is a plan of No. 583, by Messrs. Hornsby and Sons, called their 
" Manchester Mower," on a scale of i inch to 1 foot, which the Judges highly 
commended. The gearing is of the same proportions as in Ncs. 580 and 582,. 
but with a finger-bar pin-jointed to the main frame a, which is of cast iron, 
the throw of the crank being the same. 
The diflerence in the arrangement of gearing on the frame, jilan of frame, 
and increased length of the connecting-rod, which is 23 inches, will be- 
sufBciently shown by the drawing. 
1 commence the description of a few other machines with 
that of No. 181, made and exhibited by the long-established 
and extensive firm of Messrs. Samuelson and Co., of Banbury, 
as it stands high in merit, more especially in respect to 
lightness of draught ; it was also first in number of points after 
the prize machines, and, with No. 183 by the same ^maker, 
was highly commended by the Judges. 
SamueJsoti and Co.'s Mowing Machine, i\'o. 181. — In Fig. 10 is given the 
full view. 
Fig. 11 represents an arrangement for lifting by hand the finger-bar at the 
the pleasure of the driver, somewhat similar to that in their other machines ; but 
as all cannot be described, it may be of interest to give it here, a is a part 
of the main framing ; b b the shoe and finger-bar ; c a chain attached by a 
loose link to the extension-bar d, running under a half-pulley attached to the 
frame, and connected with a wood-lever e (Figs. 11 and 12) ; g (Figs. 11 and 
12) is the drauglit-pole ; f shows front view of pulley d, shown in Fig. 12. It 
will be seen that when the chain is slack the knife is free to act upon its 
natural bearings ; when tightened by the driver pulling back the wood-lever e, 
the chain pulls down the extension-bar n, which renders the beam rigid from 
end to end, at the same time lifting the beam and knife over any obstacle. 
Fig. 12 shows a side view of Samuelson's peculiar arrangement of the draught- 
chain, by which, in case of any undue draught, not absolutely necessary in the 
ordinary working of the machine — such as an obstacle of exti'aordinar}' resist- 
ance — the knife-bar is raised by the pull of the horses so as to allow it to 
ride over such obstacles. This arrangement has been applied to all the moweis 
and combined machines of these makers since 1868. It will be noticed that 
by the draught being taken from the extreme end of the pole, there is a tendency 
to raise the other end, and thus, when the machine is cutting, the pressure 
upon the horse-collar is removed, c c is the draught-chain, one end of which 
is attached to the whipple-tree, and the other to the tail-end of the pole- 
bracket A, adjustable by the three holes iii; it runs under the pulley n 
attached to the main frame, and over another pulley, D, attached to the front 
portion of the drawing frame. It will be seen that the draught-chain a can 
thus be adjusted at either of the three holes, or by varying the position of the 
pulley B, with respect to the main axle, for which provision is made by having 
two or more holes in the main frame, to which the pulley can be fitted. 
Fig. 13 is a plan of the main shoe, with a part of the knife and finger-bar; 
and Fig. 14 shows the side view of it. To disconnect the connecting-rod 
A, in both figures, the spring-catch b is drawn out, and the pawl c, which is 
pivoted, is raised, and allows the rod a to spring out of the knife-bar head E. 
Fig. 14 is the guide to the head of the knife-bar e, and also forms a means 
of oiling by means of the reservoir for oil, g. 
Fig. 15 shows the pawl c, raised to allow the knife-bar bead to be discon- 
nected, and the dotted lines show it in its proi^er position.
