Improvements in Haymakers.
We RICHARD WILDER JAMES WILDER and HENRY WILDER all of Wallingford in
the County of Berks Engineers do hereby declare the nature of this invention to be
as follows:-

!.
The object of our invention is to provide a hay maker wherein the drum or barrel
carrying the prongs or forks revolves upon the same spindle or axle as carries the
travelling wheels so that the said drum or barrel may rise and fall with the axle and
wheels being in a direct line therewith when passing over uneven ground thus
preventing undue strain upon the gearing.
We also provide means whereby the periphery of the prong drum may be
expanded or contracted so bringing each prong closer or further from the ground as
may be found desirable. Our invention is further designed to provide other novel
and useful improvements in such machines.
We make our prongs of preferably tempered steel wire bent into a kind of half
loop at the top then with each limb twisted round the other and finally the ends of
the wire diverge to form the prongs.
The prong holders are divided longitudinally and recessed to receive the prongs
placed between them when the halves can be bolted up so holding the prongs
firnily.
The prong heads are supported and held by spring holders bolted to the prong
drum, the bolts and holders being so set in the prong drum that the said holders
may be swivelled on their bolts, the holders carrying pins taking in holes in the
drum plate or vice-versa. These holes (or pins) are arranged in radi struck from
each bolt, therefore to expand or contract the drum the spring holders are pulled
with their pins from one hole in the prong drum and adjusted into other holes.
We use driving gear as follows, on the axle of the machine is a large sprocket
wheel and also a smaller wheel on the prong drum. A pair of first and second
motion shafts are mounted on the frame communicating by suitable toothed gearing.
The chains from the sprocket wheels carried by these shafts run as follows. The first
motion chain from the large sprocket wheel on the travelling shaft goes to the lower
sprocket wheel on the frame which by the toothed gearing drives the upper sprocket
wheel whose second motion chain runs to the sprocket wheel on the prong drum.
We also use an arrangement of ratchet gear to keep the prong drum idle whilst
travelling. The ratohet is mounted on a plate attached to the travelling wheel (or on
a. portion of the travelling wheel). On said plate is mounted a pawl held against
the ratchet by a spring. This pawl carries a hook or handle with a second hook on
the plate, thus the pawls can be easily raised from the ratchets for travelling.
We also provide a reversing and stopping action worked by a lever and rod, the lever
being advantageously mounted on a quadrant or like stop frame. The rod goes to a
rocking plate moving on a stud on the frame and carrying a pair of spur wheels to
engage with the sprocket wheel shafts so that by moving the lever and rod the
machine may be reversed or stopped.
We may if desired provide adjustable idle pulleys to take up the slack of the
driving chains.

Improvements in Haymakers.
We RICHARD WILDER, JAMES WILDER and HENRY WILDER all of Wallingford in
the County of Berks Engineers 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:
The object of our invention is to provide a haymaker wherein the drum or barrel
carrying the prongs or forks revolves upon the same spindle or axle.as, carries the
travelling wheels so that the said drum or barrel may rise and fall with the axle and
wheels (being in a direct line therewith) when passing over uneven ground thus
preventing undue strain upon the gearing. We also provide means whereby the
periphery of the prong drum may be expanded or contracted so bringing each prong
closer or further from the ground as may be found desirable. Our invention is
further designed to provide means whereby the action of the prong drum may be
reversed or the machine thrown out of gear when travelling on roads or the like.
Referring to the accompanying drawings and to the figures of reference marked
thereon
Figure 1 is an elevation of driving and reversing gear.
Figure 2 is an enlarged view of the driving and reversing gear showing the
machine reversed.
Figure 3 is an elevation of the prong drum showing the method of contracting and
expanding the same.
Figure 4 is an elevation of the ratchet arrangement fixed to the side of the driving
wheel 1 for throwing the machine out of gear.
Figure 5 shews the rocking plate with arrangement of wheels for reversing the
machine.
The spindles and spokes of the wheels are for the sake of clearness omitted in the
above figures.
1 is a driving wheel of the improved haymaker constructed according to our inven-
tion and which carries on its axle a large chain wheel 2. By means of this wheel 2
an endless chain 3 communicates motion to a smaller chain wheel 4; mounted on
the same spindle as the wheel 4 is a spur wheel 5 which engages with another spur
wheel 6 mounted on a rocking plate 7; this wheel 6 in turn imparts motion to a&
toothed wheel 61 which engages with the wheel 8. On the same spindle as this
wheel 8 is mounted a chain wheel 9 from which a chain 10 conveys motion to the
chain wheel 11 mounted on the prong drum.
The prong drum may be mounted rigidly on the main axle of the machine and in
this case the wheels are mounted so as to revolve loosely thereon so that the axle may
have independent motion or it may be carried on a separate hollow sleeve or tube
encircling the main axle. The whole of the gearing is mounted on a bracket 12 fixed
to the end of the frame 13.
To reverse the motion of the prong drum the handle 14 is simply moved to the
right or left on the quadrant 15 which pulls the rod 16 moving the rocking plate 7
and so bringing the disengaged spur wheel into gear. This rocking plate is pivoted
on the shaft carrying the wheels 4 and 5 and at its top is provided with a stud 17
which slides in a slot 18 in the bracket 12.
The method of contracting or expanding the prong drum is shown in Fig. 3. The
prong heads 19 are supported and held by spring holders 20 bolted to the prong, drum
the bolts and holders being so set in the drum that the said holders may be swivelled
on their bolts 30. These holders 20 carry pins 21 taking in holes 22 in the drum
plate 23 (or the pins may be on the plate and the holes in the spring holder).
holes (or pins) are arranged in radii struck from each bolt centre; therefore to
expand or contract the drum the spring holders (thinned and tempered for this
These

page_text: purpose at 24) are pulled with their pins from one hole in the prong drum and
adjusted into other holes.
A suitable ratchet 25 is fixed to a plate 26 and a pawl 27 is held in position by a
spring 28. This ratchet arrangement is fixed to the travelling wheel so that the prong
drum may be kept idle whilst travelling on roads or the like. To raise the pawl 27
it is pulled down and kept in position by a hook 29 on the plate.
Having now particularly described and ascertained the nature of our said inven-
tion and in what. manner the same is to be performed we declare that what
we claim is:
1. In so called haymakers the mounting of the prong drum upon the same spindle
or axle as carries the travelling wheels so that the said. drum or barrel may rise and
fall with the axle and wheels (being in a direct line therewith) when passing over
uneven ground substantially as described.
2. In a so called haymaker the employment of adjustable prongs substantially as
and for the purposes herein described and as illustrated in Fig. 3 of the accompanying
drawings.
3. In a so called haymaker the arrangement and combination of parts substantially
as hereinbefore described and as illustrated by the accompanying drawings.
