COMPLETE SPECIFICATION.
Improvements in Hay Rakers.
I, GEORGE CHARLES NEWTON BRYAN, of Fir Grove, East Hoathly, in the
County of Sussex, late Captain Royal Munster Fusiliers 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, that is to
Say :-
This invention relates to improvements in hay rakers and has for object as
hereinafter particularly described to provide a machine which shall automatically
and at any desired intervals lay the hay in the process of haymaking in what are
termed windrows.
In haymaking after the grass is mown it is tedded or spread evenly over the
ground and then raked into windrows preparatory to being put up or rolled into
grass cocks.
Now in accordance with this invention 1 provide a machine which shall rake the
hay and as it rakes and gathers same up shall deposit it automatically at regular
and at desired intervals in the lines or rows, called windrows.
And in order that this my invention may be fully understood and readily carried
into effect I will now proceed to describe same with reference to the accompanying
drawings and to the letters and figures of reference marked thereon, similar letters
indicating like parts in each of the figures, that is to say :-
Fig. 1 is a perspective view of a windrowing machine constructed in accordance
with this invention and Fig. 2. is a sectional side elevation of the machine shewing
in detail the arrangement and working of the parts for automatically at required
intervals raising the rake and allowing the hay gathered by it to lay in rows or
wedges.
a is the frame of the machine preferably of a rectangular shape mounted upon
wheels b b. c. c. are ratchet wheels carried upon the axle c'. e c. are pawls, fixed
one upon the inner side of each wheel b, which take into the teeth of the ratchet
wheels c c, and which cause said ratchet wheels to revolve with, and in the same
direction as the carriage wheels when the machine is travelling in a forward
direction; but which allow of the carriage wheels turning in an opposite direction
without affecting the ratchet wheels.
Upon the inner faces of the ratchet wheels cc I have pins or studs d (two or
more of these pins or studs d upon each ratchet wheel may be employed if desired
all according to the distances required for the windrows to be apart). These
pins or studs d in each revolution of the ratchet wheels c c take upon the
projections formed upon the jiggers and depress same. The upper ends of
the jiggers are provided with pins g which work in slots formed in the ends of
the arms h. These arms are pivotted at 4' to the side frames a of the machine.
At their other ends the arms have slots in which work the ends of the tine
holder i. As in their revolutions the pins d engage with the projections fl the
jiggers fare depressed and the ends of the arms h to which they are connected are
also lowered and (as these arms are pivotted) their other ends are in consequence
raised. And as they rise so will they lift the rake or tine holder i from the
position shewn in Fig. 1. to the position shewn in Fig. 2. This latter will again
fall when the pins or studs d clear the ends of the jiggers f. See Fig. 1
In Fig. 2. the rake is shewn in the raised position the pin or stud d on ratchet
wheel c being shewn engaged with the projecting end f1 of the jigger f. It will be
observed that for every revolution of the wheels the rake is raised once and hence
one windrow will be formed for each revolution.
Should it be desired that the windrows be placed in closer proximity one with

page_text: another one or more pins or studs d may be added to the ratchet wheels and thus
shorten the intervals between the rake raising actions aforesaid, kk are the slotted
guides fixed at back of the machine on the frame a through which the tine holder i
works.
The machine as above described may be drawn by manual or horse power as
desired and as a means of adjustment of the shafts I form the frame with extending
arms to which the shafts m m are attached by screw pins or bolts n.
These arms I form with a downward curve l' which may have two or more
apertures therethrough in either of which according to requirement the aforesaid
screw pins or bolts may be inserted for attaching the shafts.
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 :-
1st. In hay rakers automatically raising and lowering the rake for the purpose of
depositing the hay gathered by it in ridges or windrows; substantially as in the
manner set forth.
2nd. In hay rakers the combination of rake pivotted by supporting arms to frame
of the machine and provided with jiggers f; ratchet wheels or discs provided with
projecting studs or pins; and pawis; all substantially as and for the purpose
hereinbefore described and shewn in the accompanying drawings.
3rd. The general construction combination and arrangement of parts forming
my improvements in hay rakers, substantially as hereinbefore described and
shewn.
