PROVISIONAL SPECIFICATION.
Improvements in and relating to Machines for Turning the Swath
for Haymaking or other Purposes.
I, THOMAS MARTIN JARMAIN of Haseley Iron Works near Tetsworth, Oxon, Agri-
cultural Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and relating to machines for turning
the swath for haymaking or other similar purposes and my invention consists
in a machine baving a series of blades which are pivotally supported at one end
by means of suitable arms which arms are pivotally connected to a revolvable
disc or the like and which blades are also pivotally connected by means of
suitable rods to an eccentric-strap fitting on a fixed eccentric the arrangement being
such that when the disc is revolved the blades are carried with it and the eccentric
which is suitably arranged or set for this purpose-causes said blades to have a
"sweeping" motion imparted to them when said blades are bought nearest to the
ground. By these means each blade as it approaches the ground, lifts up and turns
the swath the "sweeping" motion of said blades enabling a comparatively wide swath
to be readily turned.
The frame which carries the parts referred to is preferably pivotally carried by the
axle of the machine so that the whole apparatus may be swung in such a position as
to make the machine more compact for transport purposes.
I wish it to be understood that I do not confine myself to any particular arrange-
ment of the different parts and I may employ any suitable mechanista for revolving
the disc referred to when the whole machine is in motion.
Further any desired means may be employed for imparting motion to the blades,
which blades are preferably serrated on their outer edges.
If desired I may also provide my improved machine with suitable guides or indica-
tions by means of which the driver of the machine may know that the revolving
blades which are preferably arranged at the back of the machine-are in a position
to turn the swath. I may also provide my improved machine with two or more sets
of blades so that two or more swaths may be simultaneously turned.

for Haymaking or other Purposes.
I, THOMAS MARTIN JARMAIN of Haseley Iron Works, near Tetsworth, Oxon, Agri-
cultural 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 improvements in and relating to machines for turning the
swath for hay making or other similar purposes, of the kind described in my former
Specification No 20795 of 1894, and my invention consists in a machine provided
with one or more sets or series of revolvable blades which are adapted to lift up and
turn the swath.
In order that my invention may be readily understood reference is made to the
accompanying drawings wherein like letters indicate corresponding parts throughout
the several figures and in which :-
Fig. I. Shows my invention in side elevation the top and bottom blades only-for
clearness-being shown.
Fig-II-Shows-a-series-of-fixed-blades.
Figs. 2 & 3 H.-&-IV show details hereinafter referred to.
In carrying out my invention I support on the axle A a bearing B in which a
spindle a is fixed, say by means of a pin or eettar cotter b, The the outer or free end
of said spindle a being supported by means of a trailing wheel or equivalent C. The
axle A has fixed to it a bevel wheel D with which a bevel pinion E capable of
revolving on the spindle a gears and to the said pinion E is fixed a disc F-shown in
front and side elevations respectively in Figs 32 and 4 3-which is revolved when
the axle A is revolved during the time when the machine is being drawn along. The
disc F is provided with pins f to receive the inner ends of rods or bars G as shewn
and said disc is also provided with stops or the like f¹ against which stops the bars.
are normally pressed by means of springs H. The bars to G and springs Ḥ are held
in place by means of a plate g and one end of each spring enters into the rear part
of the stops f¹ and the other end is held in position by means of pins or the like f2
fixed to the bars G.
The outer or free end of each bar G is pivotally attached to preferably a toothed
blade or wing J which blades must consequently revolve with the disc F when the
machine is in motion and for the purpose of imparting a more or less sweeping"
motion to the blades or wings J. I also pivotally connect them to the strap K of an
excentric L which is fixed to the spindle a the arrangement of the whole being such
that when each blade is brought to about its lowermost position its outer or free end
will be caused to more or less sweep along the ground and thereby said blade or wing
will lift up and turn a swath of considerable width.
The blades or wings J may, if desired, be fixedly attached to the arms G or they
may be integrally formed and fixed to the end of an adjustable spindle. as-shown-in
Fig-2. In any event when the revolving blades or wings-after proper
adjustment are brought in contact with the swath they will lift up and turn said
swath.
I prefer the frame of the machine which carries the parts referred to, to be pivotally
supported by the machine so that the mechanism may be swung into such a position
that the whole machine is rendered more.compact for transport.
I wish it to be understood that I do not confine myself to any particular arrange-
ment of the. blades or wings or to any particular means for causing them to revolve
when required. I also prefer to provide suitable means for throwing the bevel

page_text: wheel D and pinion E out of engagement so that the blades may remain stationary
even when the machine is being drawn along. I also prefer to provide my improved
machine with one or more guides to enable the driver to readily guide said machine
along the swath and in practice I find that two sets of wings for each machine are most
suitable although I do not confine myself to such number, and if more than one series
of blades be provided I fix said series with the necessary mechanism in such a manner
as to be readily adjustable relatively to one another on the axle.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is
1. A machine for turning the swath and having a series of blades such as J,
capable of being revolved substantially as described and illustrated.
2. In a machine for turning the swath, blades J pivotally attached to arms G
and guided or moved by means of an excentric substantially as described ard
illustrated.
3. In a machine for turning the swath the combination of a fixed spindle a
supporting a revolvable disc F carrying bars G to which are connected blades or
wings J, a fixed excentric L having a strap K to which said blades are also pivotally
attached, a trailing wheel and bevel wheels D and E all for the purposes and acting
substantially as described and illustrated.
