PROVISIONAL SPECIFICATION.
Improvements in Hay-makers or Hay-tedders.
I, JOHN HARRISON, of the Harrison Patents Company Limited, of Lincolnshire
Iron Works, Stamford, in the County of Lincoln, Engineer, do hereby declare the
nature of this invention to be as follows :—
This invention relates to improvements in hay-makers or hay-tedders and has for
object to provide a rotary hay-maker ortedder with tedding forks having a feathering
or kicking action.
For this purpose I mount the forks on shafts parallel with the central axle, the
shafts being partially rotated so as to give the forks the required feathering or
kicking action at the desired point by suitable means such as a cam advantageously
made adjustable.

COMPLETE SPECIFICATION.
Improvements in Hay-makers or Hay-tedders.
I, JOHN HARRISON, of the Harrison Patents Company, Limited, of Lincolnshire
Iron Works, Stamford, in the County of Lincoln, Engineer, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to hay-makers or hay-tedders and has for object to provide
an improved rotary hay-maker or tedder with tedding forks having a feathering or
kicking action.
For this purpose I mount the forks on shafts parallel with and upon the central
axle, the said shafts being partially rotated so as to give the forks the required
feathering or kicking action at the desired point by suitable means such as a cam
advantageously made adjustable.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a plan partly in section of a hay-maker or hay-tedder constructed
according to my invention; and,
Figure 2 is a sectional view of the same on the line xx, Figure 1:
Figure 3 is a view of a detail.
a is the framing of the machine, b is the main shaft or axle thereof, and c, c are
the travelling wheels.
d, d are the barrels of the hay-maker, each of which is composed of a series of
shafts d', d carrying the forks e, e, and two crosses f, f rotating upon the central
shaft band having the shafts d', d' pivotally mounted in their arms.
At the outer
end of each of the shafts d' is fixed a lever g carrying a roller h.
i, i are cam-plates each having a groovej in which the rollers h, h run, the said
cam-grooves being shaped advantageously as shewn in Figure 2 so as to cause the
forks e, e to make their proper feathering movements.
Motion is imparted to the barrels d, d by the following means :-
Upon the shaft b at each end is a bush k, at the outer end of which is fixed one
part of a clutch and at the inner end of which are two arms m, m carrying
pinions n, n, which pinions engage with a ring of teeth o formed integral with the
cam-plate i. The wheels c, c rotate upon the bush k and sliding upon the hubs
Pm d

page_text: of the said wheel c are the clutch parts p, p designed to engage with the parts 1, 1.
Whilst the parts p, p are out of engagement with the parts 1, the travelling wheels
rotate freely upon the bush k: when, however, the parts of the clutch-box are in
engagement, the travelling wheels will be locked to the bush k so that the latter
will cause the rotation of the said bush. As a result of this movement of the bush
the wheels n, n will move around within the ring of teeth o and as they engage
with gear-teeth o' upon the hub of one of the crosses ƒ of each barrel they will
cause the rotation of the said barrels.
The parts p
of the clutch-box are operated simultaneously from a lever
mounted upon the front bar of the frame a (as shewn most clearly in Figure 3) and.
connected with the clutches through the medium of rods r, r and bifurcated spring
levers s, s engaging in grooves in the parts p, p of the clutches.
In order to adjust the height of the barrels relatively with the ground I make use
of the links t, t, each of which is connected at one end to the cross-bar of the
frame a and at the outer end, which is hook-shaped, adapted to engage in one of a.
series of holes u, u formed in the cam-plates i, i.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. A hay-maker or hay-tedder the forks of which are carried by barrels rotating
upon the main axle of the machine and all of which have a feathering or kicking
movement imparted to them through the medium of levers engaging with fixed cams,
substantially as described.
2. In a hay-maker of the kind referred to in the preceding claiming clause, the
arrangement of mechanism for communicating the movement of the travelling
wheels to the said barrels, substantially as hereinbefore described.
3. The manufacture and use of the improved hay-maker or hay-tedder herein-
before described and illustrated in the accompanying drawings.
