Improvements in and Applicable to Horse Gears.
I CARL FERDINAND PAUL HÜBNER, Estate Bailiff of Götz near Gross Kreuz in
der Mark in the Kingdom of Prussia, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to horse gears and consists in an improved arrangement for
effecting an equalisation of the tractive efforts of the animals working the gear, so that
the tractive power of each animal is fully utilised and not one of them over exerted
while another is needlessly spared as is frequently the case with the horse gears
previously in use.
On the sheet of drawings appended hereunto figure 1 shows my improved arrange-
ment in top view; figure 2 the same in side view; figure 3 a detail of the same on an
enlarged scale.
The gearing of the horse gear may be constructed in any ordinary manner and one
of the most usual and simple gears is represented with my improvement applied to it.
The top of the upright shaft a. rotating in the frame A carries the boss b. with wings
for the reception of the poles B B¹ B² B³. Inside the frame A the shaft a carries the
bevil wheel C. in gear with the bevil pinion c. Upon the shaft of the pinion c. the
spur wheel c is fixed which drives the pinion 2 on the horizontal shaft D.
The animals are yoked to the whipple poles E E E E³ which are linked to the ends
of the bell crank levers e e e e³ which are fulcrumed upon studs in the ends of the
poles.
The other loose ends of bell crank levers are again connected by a special arrange-
ment of links by means of which the equalisation of the force is obtained in a simple
manner. Resting upon the poles B B1 B2 B3 and surrounding the cross piece b. a
square of links is arranged, the sides ssss of which are connected to the loose ends
of the bell crank e e e e by draw bars tttt in such a manner that each two
adjoining sides are moveably connected to one of said draw bars. This connection
may be made by means of pins passing through eyes at the ends of the links, but is
more conveniently effected by means of three rings (figure 3) one of which 7. runs
through an eye or hook of the draw bar and is linked to the other rings 2 each of
which passes through an eye or hook on one of the links forming the square.
The draw bars t¹³ ³ are likewise connected to the bell cranks e e e² es by means
of swivel joints or hooks.
If all the animals draw with equal force on the whipple poles, the links form a square
as shown by figure 1 in full lines. This square however is at once dislocated when
one of the animals, for instance the one working at the pole B pulls with greater force
than the others, as shewn in dotted lines, and the tractive force is thereby equalised.
In consequence of the moveable connection of the links forming the side of the
square to the drawbars the square can adjust itself in any position corre-
spondingly to the force exerted upon the different poles so that even if all four
animals work very irregularly an equalisation of the power is obtained.
The improved tractive arrangement hereinbefore described can be easily applied to
existing horse gears, as only the holes for the studs of the bell crank levers have to be
bored in the ends of the poles in order to attach the whole mechanism without any
alteration of the other gear.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is

attach them to bell crank levers e e e 3 fulcrumed on the ends of the poles B B B² B³
and having the whipple poles attached to their other ends substantially as hereinbefore
described and illustrated by the drawings and for the purpose set forth.
