page_text: I, ADAM CARLISLE BAMLETT of Thirsk in the County of York Agricultural
Engineer do hereby declare the nature of this Invention to be as follows:-
This Invention consists in certain improvements in reaping machines for giving
greater facility for regulating the cutting height of the knife. I mount the bracket
that carries the road wheel on the axis of the intermediate shaft and partly support
the weight of the machine by a spring connected to this bracket and to the main
frame. On the underside of the bracket I form an arm to which à chain is
attached, this chain passes round a pulley on the underside of the main frame it
then passes under the platform of the machine round a pulley at the corner of the
platform and is attached to a pivotted bar on which the corn side wheel is mounted.
I make the road wheel axle hollow with a spindle through it that carries a small
pulley at its inner end (this pulley is attached to the frame by a chain) and a lever
at its outer end, this lever is furnished with a pawl that takes into a ratchet on
the main axle, hence it follows that when this lever is raised or depressed it acts
both on the road wheel and on the corn side wheel raising or lowering the machine
and thus regulating the cutting height of the knife. For altering the pitch of the
platform I use a lever connected to the draft pole and the front part of the frame.

page_text: DESCRIPTION OF THE DRAWINGS.,
Figure 1 is a side elevation of a portion of a reaping machine arranged in
accordance with my invention and provided with apparatus for regulating the
cutting height of the knife.
Figure 2 is a plan of a portion of the same..
Figure 3 shows separately in plan the bracket on which is the axle of the road
wheel.
a is the road wheel and b is the main frame to which is attached the finger bar c.
d is the crank for driving the knife its axis passes through the frame.b and has
upon it at its upper end a pinion engaging with a bevilled wheel upon the inter-
mediate shaft e, thus the knife is driven in the usual manner, el is the pinion on the
shaft e. which gears with the ring of teeth upon the wheel a. f is the pole to which
the horses are harnessed, it is connected with the frame bat b¹. g is the bracket
on which is the axle of the road wheel a it has at one end a sleeve g¹ which
surrounds the hollow bearing of the intermediate shaft and at the other is the
axle g' of the main wheel. The axle is hollow and the spindle h passes through it.
h is a pulley on one end of the spindle h and 2 is a handle with which it is
provided at the other end. i is a bar forming part of the support for the seat of
the machine The seat bracket in rear of the axle is not shown but this arm i
passing forward from the axle serves to support it and keep it in position; it is
connected with the pole by a link -On the axle and also attached to the part i
there is a ratchet k and a pawl h* carried by the hand lever h³ which engages with
this ratchet to keep the hand lever in any position in which it may be placed.-
Z is a chain extending downwards from the pulley ¹ to the frame b. When
the handle h is drawn rearwards the chain is wound up upon the pulley the
frame 6 is lifted and the distance of the fingers from the ground is increased but the

page_text: inclination of the fingers is not materially altered. For the purpose of varying the
inclination of the fingers as may be required the frame b is provided with a pro-
jecting born 6*, this is connected by a link with the arm m³ of a hand lever m
which by means of a rack shown in the drawing can be retained in any desired
position. When this lever handle m is pressed downwards the frame 6 moves
around the axle of the main wheel and the inclination of the fingers to the ground
is altered. In respect however to these parts b*, m, and m¹ I make no claim,
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The arrangement substantially as herein described for regulating the height
of the knife consisting of a bracket moveable about the intermediate shaft and
having upon it the axle of the road wheel and a spindle passing through the said
axle and carrying at one end a pulley or arm connected by a chain (or like
connection) with the frame and at the other a hand lever by which the spindle
may be turned.
2. The arrangement substantially as represented by the annexed drawings.
