PROVISIONAL SPECIFICATION.
A Haymaker for Use with Grass, Clover, or the like.
JOHN DOBBING Agricultural Engineer Commercial Street Darlington County
of Durham I do hereby declare the nature of this invention to be as follows:-
This combined haymaking machine consists in a new arrangement for taking the
hay of the ground and turning the same completely over without damaging the hay
or shaking the seeds out of same to accomplish this I make a reel triangular square
or round fitted with two three or four rows of teeth Each row of teeth is fitted
in two parts set at a given angle and hinged those teeth being held in position by a
spring either flat volute or spiral or india rubber as may be required, the teeth
being so arranged that on coming in contact with any uneven surface whilst
working they yield to such uneven surface and are brought back into position by
the spring before named, the machine revolving to meet the hay and so taking up
the hay carrying the same over and delivering behind machine To prevent these
teeth from taking up more hay than they can deliver or to give the machine a
regular feed I fix a dividing rake or set of teeth the full length of machine and in
such a position from the ground that in case of any heep or more than ordinary
thickness of bay this dividing rake only admits each set of teeth to take its own
portion dividing the hay proportionately over the whole of the teeth the reel
traveling as slow as possible to do the work and is driven by gear wheels connected
to traveling wheels by ratchets and thrown in and out of gear by spring catch or
clutch this machine may be worked by horse or other power.

A Haymaker for Use with Grass, Clover, or the like.
I, JOHN DOBBING, Engineer, of Commercial Street Darlington, in the County of
Durham, 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 combined haymaker consists in a new arrangement for taking the hay or
grass off the ground and turning the same completely over without damaging the
hay or shaking the seeds out of same.
I accomplish this object by means of a machine as 'illustrated in the accompanying
drawing in which
Fig. 1 is a transverse sectional view corresponding to which Fig. 2 is an end
elevation and Fig. 3 a plan.
Figs. 4 to 8 inclusive are some of the details drawn to a larger scale.
In carrying out my invention I construct the machine with a reel a of a
triangular shape as shown in the drawing or of a square, round or flat shape if
preferred. This reel a is furnished with two three or more rows of teeth b the
triangular reel shown having three rows of teeth attached to it and the mode of
attachment is designed to enable the teeth on coming into contact with any uneven

surface whilst working to yield accordingly until they get clear of such uneven
surface when they are automatically brought back into position by the action of a
spring such as a flat volute spiral or india-rubber spring. A suitable device for
this purpose is illustrated in Figs. 4 and 5, Fig. 4 being a sectional view taken on
line of Fig. 5, which is itself a sectional view of one corner the reel a.
teeth bare mounted in the form of a rake on the cross bar c extending the full
length of the reel, and journalled into the end plates a¹ thereof on each of which is
cast a stop piece d against which the cam shaped chock e is seated by the action of
the spring. This enables the teeth to yield to obstructions with a constant
tendency to return to the working or normal position.
The reel a is driven from the travelling wheels g by means of spur wheels
geared together to rotate the reel a as slowly as possible for doing the work.
Suitable provision is made for throwing the spur wheels in or out of gear as
required, such as the device illustrated in Figs. 6, 7 and 8 in which Fig. 6 is a
sectional view taken on line y y of Figs. 7 and 8 which are corresponding views in
front elevation and plan. In this device a spring catch or clutch engages with a
ratchet when the wheels h are in gear, and is disengaged therefrom by pulling
out the handle or trigger to the dotted position shown in Fig. 8.
My improved haymaker being constructed and fitted together as hereinbefore
described it will be seen that as the teeth advance along the ground the bay,
grass or other material is lifted from the ground and lodged against the side of the
reel, and as the reel turns over, the hay or other material is turned over with it and
deposited in the inverted position at the rear of the machine so that the damp side
is exposed to the sun and wind.
Having now particularly described and ascertained the nature of my said inven-
tion and what manner the same is to be performed, I would here observe that
I do not find it necessary to provide a dividing rake as mentioned in my Provisional
Specification for the purpose of regulating the feed to each set of teeth and I have
accordingly omitted it from my machine as not being essential to my said invention,
and I declare that what I claim is :-
The combination of parts constituting a machine by which the hay, grass or other
material is turned over by means of teeth secured to a reel which is rotated and
operated substantially as and for the purpose as hereinbefore described with
reference to the accompanying drawing.
