do hereby declare the nature of my said invention for AN IMPROVED ANIMAL
POWER ENGINE to be as follows:-
By the mechanism illustrated in the accompanying drawing, animal draught-
power is converted in to rotary motions, for general purposes, without tireing or
mentally injuring the animal as heretofore the cases have been by the old methods.'
Figure 1 is a side view of the entire machine and by a dotted line showing a
draught-animal in working position; Fig. 2 is a top view of same without the
animal, and by its sloped shape, showing front and back view likewise. Figs. 3, 4,
and 5, are enlarged details showing construction movements and connections of the
principal parts. Fig. 6 is a half mechanism of the above, composed thereof and
I desire to secure it with above under a patent.
Similar letters refer to similar parts throughout the several views. The frame
work is composed of side framings A. A, end framings bb, and top framing c, and
are combined of such strength as to resist the strain of the animal.
The top cross bars of end framings bb, are in the direction above the animal's
hipp and shoulder joints; to thise cross bars are jointed the perpendicular moving
lever treadles & d, which are shaped so as to hang side ways down of the animal's
legs and going underneath its footsoles, and are flat on the tops of the underneath
going parts for the animal to stand on. At the front thereof is a free rod e, secured
at its ends. On this rod is a toe-cap j, moveable either way, and a chain in a
rubber tube g, for fastening the animal's boof, see Figs. 4 and 5. As shown in
Figs. 1 and 2, treadles d, are connected left front with right hind, and right front
with left hind by rods hh. Each pair of treadles is connected by a rod i, to the
out side of a wheel k, at such a point, that both points are in a straight line with'
center of rod 2, where the wheels kk, are fastened to the ends.

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:-
My invention relates to such mechanisms by which animal's draught power is
converted in to rotary motions, and has the quality of a motor.
The objects of my improvements are, first, to obtain a speed of one wheel-
revolution to two step-motions from the animal's legs direct, whereby is no loss of
power by frictions; second, to avoid tireing and mentally injuring the animal;
third, to retain the power of the animal longer as if working on a flat; and fourth
to limit the large space necded heretofore.
I attain these objects by the mechanism illustrated in the accompanying drawing,
in which
Figure 1. is a side view of the entire machine and by a dotted line showing a
draught animal in working position; Fig. 2. is a top view of same without the
animal, and by its sloped shape showing front and back view likewise; Figs. 3, 4
and 5, are enlarged details showing construction movements and connections of the
principal parts; Fig. 6. is a half mechanism of the above, composed thereof and
I desire to secure it with the above under a patent.
Similar letters refer to similar parts throughout the several views.
The fram-work is composed of side framings A. A, end framings b b, and top
framing o, and are combined of such strength as to resist the strain of the animal.
The top cross bars of end framings bb, are in the direction above the animal's
hipp and shoulder joints; to these cross bars are jointed the perpendicular move-
able lever treadles d d, which are shaped so as to hang sideways down of the
animal's legs and going underneath its foot soles, and are flat on the top of the
underneath going parts for the animal to stand on.
At the front thereof is a free rod e, secured at its ends; on this rod is a toe-cap j
moveable either way, and a chain in rubber tube g, for fastening the animal's hoof,
see Figs. 4 and 5.
As shown in Figs. 1 and 2, treadles & are connected left front with right hind,
and right front with left hind by rods h h.
Each pair of treadles is connected by a rod i to the out side of a wheel k, at
such a point that both points are in a straight line with center of rod 2, where the
wheels kk, are fastened to the ends.
The last said is an exact double throw-crank-action, which, when turned moves
the treadles so, as to suit the animals leg-movements for work.
The wheels are made with a split spoke, through which from the inner sides is
passed a set-screw in to the crank pin, for to lengthen or shorten the throw, and
thereby to set the treadles's sweeps to suit the animal's natural steps; and are
ratchet at the inner side on the inside of the rim, not visible in the drawing. In
which m, a short and thin steel-blade, such as a quarter of a table knife blade with
one end lays and the other und loose fastened to a bar.

This secures the wheels moving direct in one direction, and its lightness renders
it almost noiseless. ⚫
Under Fig. 3. a treadle & is shown in full with its bridging-piece for strength-
ening the same.
A chain in a rubber tube g, for fastening the toe-cap j, on to the animal's hoof is
this and so employed 1
The chain is made so long as just to be impossible for the animal to draw, its
hoof through, and the rubber-tube is made and fastened at the ends to the chain
ends, so short that it just keeps laying itself and chain in the notch above the hoof.
When the animal pulls the rubber stretches to the length of the chain, and then
softeness the pressure of it.
The top part of toe-cap j is stretched to right and left of the hoof, and thereby
has to move with the hoof to right and left as the animal pleases to move, and is
made of steel to obtain lightness and strength. nn, are lever handles of spring
wire bent to a round corner square, of which one part is short and passed through
the upper thickness of the toe-cap from the outside and riveted from the inside;
the longer part is moveable upwards, so it is passed through the end link of the
chain moved downwards and pressed beside a dowel as shown in Fig. 3. and so is
kept secure; lifting it up, the chain slips off itself.
There are two for the convenience of the operator to use.
Fig. 6. the half
mechanism is simply a lengthened side frame A bend to a half round in the middle
and connected to an end frame b; and the connection rod i is jointed, and moves
with a slider in a groove.
The whole frameworks and treadles are made of wrought iron or steel tubes,
where the connections and bends are cast on to, so as the enlarged detail part
Fig. 3. shows.
The top cross c and side frames A. A are held by bolt-screws, passed square
through tube and tenon for the taking the engine in parts for transport.
The free rod e, with toc-cap j can be changed to the other side of the treadle's
platform, to enable the animal to be placed the other better way.
To make the engine do to be worked by an animal some inches longer or shorter,
I keep the same length of rods hh, which connecting centers are equal to the length
of the apartness of the treadles's upper centers, and give them connections out of
the treadles's centerlines, whereby the longer or shorteress is obtained.
For this object I make the bottem part of the treadles where the lower connection
rod h is, wider as shown in the detail Fig. 4.
And for this changing the length, rod i is held by a set screw at the treadle's
end to change the length thereof to the perpendicularness of the treadles.
To obtain a more silent working of the engine I line the treadles's platforms and
toe-caps with rubber.
Pieces of wood planks are to be layed on the ground level with, and enclosing
the treadles's platforms, before an untrained animal is attached to the engine, which.
is to be protected from rusting by calvanising or painting.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim and desire to secure by letters patent is

chain in a rubber tube g, held by lever handles n n, to a sideways of an animal's
hoof extending toe-cap j, which is moveable either way on a free rod 6, which
is secured at its onds to one side of the platform of a treadle d, all substantially as
set forth.
2. For an animal power engine the perpendicular moveable lever treadles d,
which are borne by bars in the direction above and across of an animal's hipp
and shoulder joints going sideways down of an animal's legs, strengthened by a
bridging-piece and going underneath an animal's hoof, being flat on the top of
