I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and Engineers,
of 35, Southampton Buildings, Chancery Lane, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention relates to horse gins or motive power apparatus actuated by horses,
and it has for its object to provide means for equally distributing among the number
of horses used the amount of traction applied to work the gin, so that if one horse
of the set slackens its pace or fails to pull, the one or more other horses are not
submitted to any undue momentary over strain, any irregularities in the traction
being equalized by the improved appliance, which accordingly, serves to spare the
horses.
The gin is provided with a horizontal beam, preferably about 6 mêtres long, to
each end of which the horses are harnessed, and it turns freely upon a central pin
or pivot fixed to a supporting cast-iron block carried by a foundation of stone
or wood.
To each end of the crossbeam a vertical iron socket is fixed, and through the
said socket passes a strong bolt, the projecting ends of which serve as a pivot
for a horizontal bell crank or angle-piece the two arms of which may be of equal or
of different length. To the said angle-piece above the beam, a lower similar one
below the beam is bolted, the latter having upward sloping arms, connected to the
upper one by bolts, thus forming a strong frame, the upper part of which may be
strengthened by a cross-bar connecting the arms. The arms of the angle piece,
if of equal length, may conveniently be one mêtre in length; if of different length
one arm may be one inêtre, the other two mêtres long.
To the outside end of the angle piece a hook is secured to which the swingle-tree
of the harness is attached.
To the inside end of the angle piece a joint or loop is pivotted, which joint is con-
nected by rings and rods to the corresponding joint of the angle piece at the other
end of the cross beam.
The central connecting rod works through a guide by which it is kept in its proper
position. To the ring connected to the joint or loop upon the angle piece a chain is
attached, the other end of which is secured to a fixed hook or loop projecting from
the beam.
Below the beam at its centre a bevel toothed wheel is fixed which, with a corre-
sponding pinion upon a horizontal shaft which transmits the rotary motion obtained
by the traction of the horses to any other mechanism outside the gin in the usual
way. If both angle pieces have arms of equal length and an equal strain is applied
to them, the connecting rods described will keep their normal position as long as the
strain on one end of the beam is not either reduced or increased, should this occur,
at one end or the other, the angle piece will at once be drawn to that side, where the
strain exceeds that of the other side, and the rods will accordingly be shifted in the
same direction. By this means the resistance against either of the two horses or
sets of horses cannot be suddenly reduced or increased.
In the case of two horses of unequal strength being harnessed to the two ends
of the cross-beam, or a different number of horses (for instance one or two at one
end and two or three at the other end), the difference of strain is equalized by
applying to one end an angle piece of different length of arms the long outer arm
Pin S

attached to one of the holes, more or less distant from the central pivot, according
to the amount of difference of strain, or two hooks or joints for two horses may
be attached to the longer arm of the angle piece.
Should the strain at one end of the beam totally cease, the chain described above
will retain the angle piece sufficiently to allow the horse or set of horses at the
other end to work on. If the horse or set of horses be put only to one end of
the cross-heam, the ring upon the joint at the opposite end of the beam is fastened
upon a corresponding hook. The driver, with little attention, will easily see, from
the play of the angle pieces and rods, which of the horses should be driven.
The size of the apparatus and of its constituent parts, as stated before, may be
varied according to the circumstances in which it is to be used.

COMPLETE SPECIFICATION.
Improved Motive Power Apparatus Driven by Horses.
A communication to me from abroad by FRANZ WENNEMEDE, of Saaringen, in the
Empire of Germany, Farmer.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of Middlesex,
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, and accompanying drawing :-
This invention relates to horse gins, or motive power apparatus actuated by means
of horses, and it has for its object to provide means for equally distributing among
the number of horses used the amount of traction applied to work the gin, so that
if one horse of the set slackens its pace or fails to pull, the one or more other
horses are not submitted to any undue momentary over-strain, any irregularities
in the traction being equalised by the improved appliance, which, accordingly,
serves to spare the horses."
And in order to make the said invention more readily understood, 1 will describe
the same with reference to the accompanying drawings, in which:
Figure 1 is a side elevation of a horse gin fitted with the improved appliance,
Figure 2 is a plan,
Figure 3 is an end view of the same,
The horizontal cross beam A of the gin preferably of about 6 metres length
turns freely upon the central shaft or pivot B secured to the supporting cast-iron
block C carried upon a bed of stone, or timber.
To each end of the said cross-beain A a closed iron socket D is secured by screws
and keys E, and through the said socket passes a strong bolt F, the projecting ends of
which serve as a pivot for the horizontal bell crank G, the two sides of which may be
of equal or of different lengths. To the said bell crank or toggle G, a lower, parallel
toggle H below the beam is bolted by its upward sloping arms, the lower toggle is
pivotted upon the same holt F and is further secured to the upper toggle G by studs
or bolts F, thus forming a strong frame, the upper part of which may be strengthened
by a cross-bar or stay K. The arms of the toggle, if of equal length, may con-
veniently be about one metre in length, if of different lengths one arm may be about
one metre and the other two metres long.
To the outside end of the toggle or angle piece G a hook L is secured to which the
swingle tree of the harness is attached.
To the inside end of the toggle G a hoop M is pivotted, the said hoop being con-
nected by means of rings N and rods O to the corresponding hoop M of the toggle G
at the other end of the cross-beam A.

page_text: The central connecting rod 0 is guided in a sleeve P to keep it in its proper
position. To the first ring N of each hoop Ma chain Q is attached, the other end of
which is secured, as at R, to a fixed hook or loop projecting from the beam A.
Below the beam A a bevel toothed wheel is mounted on the shaft B gearing with a
pinion upon a horizontal shaft, which transmits the rotary motion obtained by the
traction of the horses to other mechanism outside in the usual way.
If both toggles
or bell cranks G have equal sides and an equal strain is applied to them, the con-
necting rods NO will keep their normal position as long as the strain on one end of
the beam is not either reduced or increased, should this occur at one end or the other,
the toggle G will at once be drawn to that side, where the strain exceeds that at the
other side, and the rods N, O, will accordingly, be shifted in the same direction. By
this means the resistance against either of the two horses or sets of horses cannot be
suddenly reduced or increased.
In the case of two horses of unequal strength being harnessed to the two ends of
the cross beam A or a different number of horses (for instance one or two to one end
and two or three to the other end), the difference of strain is equalised by applying to
one end a toggle or angle piece G of different length of arms the long outer arm of
the said toggle being provided with several holes to fit the book L and the said hook
being attached to one of the holes, more or less distant from the pivot F according to
the amount of difference of strain, or two hooks L for two horses may be attached to
the long arm of the toggle or bellcrank.
Should the strain at one end of the beam A totally cease, the chain Q will retain
the toggle or bell-crank G sufficiently to allow the horse or set of horses at the other
end to work on. If the horse or set of horses be harnessed only to one end of the
cross-beam A, the ring N of hoop M at the opposite end of the beam is fastened upon
a corresponding hook. The driver, with some attention will easily see, from the play
of the toggle G and rods N O, which of the horses should be driven.
The size of the apparatus and of its constituent parts, as stated before may be
varied according to the circumstances in which it is to be used.
Having now particularly described and ascertained the nature of ny said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
An improved horse gin having secured to both ends of its cross-beam A a pivotted
toggle or bell crank G of equal or of unequal length of arms, forming a frame with
the bent bars H, bolts J and bar K, the inner ends of the two toggles G being con-
nected to each other by rings N and rods O, for the purpose of equalizing any
difference of strain at the two ends of the beam and thereby preventing any undue
strain from being put upon the animals, the said difference of strain being
neutralized by a toggle of different length of arms in those cases, where horses of
different strength or number are working at the two ends of the cross-beam, all
substantially as and for the purpose described and shewn in the drawing.
