Improvements in or relating to Hay-tedders.
A communication from CARL HUGO TEICHER, of Dippoldiswalde, Saxony; in the
Empire of Germany, Manufacturer..
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Chartered Patent Agent, 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 a portable hand-apparatus for turning or tedding hay,
which, owing to its easy and simple construction, can conveniently be manipulated
by a single workman without having to exert too great an effort, adapts itself
admirably to the configuration of the ground, and in particular may be used to
great advantage wherever the troublesome machines drawn by horses would give
unfavourable results, e.g. in gardens, or on small irregular areas, much encumbered
with trees etc. ..

The working part of the apparatus, is a shaft which catches up the bay with its
radial forks and scatters it on each side. The shaft is borne in a light, rectangular
shaped frame carried by a single wheel with a broad rim. Hence the facility of
adaptation which characterises this invention, on uneven surfaces or those beset
with obstacles.
It is also especially advantageous to arrange the machine in such manner that
the working-shaft is pivoted on the axle of the driving or running wheel, and can
thus be laid over in the opposite direction, so that the machine, without having to
turn round, can be run and worked in either direction to and fro, and thus scatter
the bay in one and the same direction.
This, the most suitable form of the machine, is illustrated in the accompanying
drawings.
Fig. 1 is a side elevation of the machine, with the frame cut through;
Fig. 2 is a plan of the same.
Fig. 3 a view, partly in section showing how the rocking shaft is mounted and
borne.
A is the broad-rimmed running-wheel whose axle is carried in bearings by a
frame consisting of two parallel straight longitudinal bars B (curvilinear in the
vertical plane) with transverse connections, in all respects symmetrical in relation
to the axle. The cross-bars b, one at each end of the longitudinal bearers B B
are advantageously made in form suitable for use as handles in pushing and
steering the machine. The frame is suspended on the axle of the running wheel
so that, at pleasure, either end can be elevated and employed as a handle, while
the other, over which, in such case, the pivoted or working-shaft thien lies, is
lowered to the ground. In order to avoid sliding contact with the roadway, the
ends of the longitudinal bearers B can be provided with small running rollers.
The rocking shaft c, fitted with the radial forks C is tubular and arranged to
rotate on the solid rod D prolonged into a nave d encircling the axle a of the
running wheel (Fig. 3). The oblique cross bars F of the frame carry the
bearings, which, for convenience of opening and closing may advantageously be
provided with hinged covers f' (Figs. 1 and 2), to be secured by pios as shown.
In one of these bearings the working shaft c is laid, when the machine can be
set to work by pushing in one direction or the other, according to circumstances
(Fig. 1).

page_text: Rotary motion is imparted to the working-shafte by the bevelled toothed ringe
on the running wheel A driving the corresponding pinion e' on c.
Various modifications in the constructive details and arrangement of the machine
can, naturally, be made without departure from the principle and scope of the
invention.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed, 'I declare that what I claim is ;-
1. A portable apparatus for hay-tedding having a single broad-rimmed running-
wheel (A) carrying a rectangular frame (Bb) wherein the working shaft (c)
with radial forks is carried in bearings so that rotary motion is imparted to it
from the running wheel by means of bevel gear substantially as described and
illustrated.
2. A modification of the machine described in Claim 1 which can be run in
either direction without being turned round and wherein the working-shaft (c) is
arranged to swing or rock on the axle (a) of the running-wheel (A) and can thus
be turned over from one side to the other of the frame which is symmetrical in
relation to the said axle and for this purpose the shaft-bearings (f) are carried by
two transverse supports (F) on the frame of the machine substantially as described
and illustrated.
