"Disengaging and Brake Mechanism for use with Horse Gears or
Gins for Actuating Agricultural and like Machinery."

I, PAUL BURMEISTER, Engineer, of 56 Hospital Strasse, Ratzeburg, in the Kingdom
of Saxony, 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 that class of machinery in which horse gins actuate or
drive the machine. Disengaging gear arrangements are already generally in use, but
they have the disadvantage that when the gear is released the winch beam of the
horse gin strikes the hind legs of the horses with the common result that the horses
either bolt or shy, and the object of the present invention is to provide a brake gear
which simultaneously with the disconnection of the horse gin from the machine
operated applies a brake to absorb the motion of the winch beam.
The present invention consists of a combined disengaging mechanism and clutches s0
arranged that at the same time the gear is thrown out of operation, brakes are put
into action for the purpose hereinbefore referred to.
The invention is illustrated in the accompanying sheet of drawings as follows.―
Figure 1 is an elevation partly in section of the apparatus.
Figure 2 is a plan.
The disengaging mechanism is arranged between the horse gin and the machine
operated in such a way that the horse gin is attached to the knuckle b, while the
shaft of the machine to be operated is attached to the jaw piece a. A shaft chas
arranged upon it at one end a jaw coupling e, which when in gear transmits the
motion of the horse gin to the machine operated, and this shaft c has also arranged
upon it a brake disc f, while fixed to the outer end of the jaw clutch e is a similar
brake disc d forming part of the knuckle piece a connected to the machine.
A compound lever n with two extension arms his pivotted at the bottom of these
extension arms respectively to two sleeves n and i, the one sleeve i being keyed to
the shaft c, while the other n is free to slide upon it. Upon the bottom of the
extension arms, and beyond the point of pivotting, brake blocks l, g, are fixed, which,
in a certain position, will bind upon the brake discs f and d.
The operation of the hereinbefore described mechanism is as follows.-When the
compound lever n is in the position shown in Figure 1 in full lines, the brakes g and
are out of gear with the respective discs f and d, and the jaw coupling e is in gear
with its other half fixed to the disc d, and thus the power from the horse gin is
transmitted from the shaft c to the machine operated. When, however, the compound
lever n is swung over to the position shown in dotted lines on Figure 1, the jaw
clutch e is pulled out by the sliding back of the sleeve n, thus disengaging the horse
gin from the machine operated, and simultaneously with this action the brake
blocks g and grip the brake discs & and f instantaneously or nearly so, stopping the
shaft c and the winch bar, and thus preventing the sudden unburdening and
unyoking of the horses, and the resulting inconvenience previously mentioned.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the said is to be performed, I declare that what I
claim is.-
In disengaging mechanism for agricultural and like machinery the provision of
brake blocks fixed upon the disengaging mechanism in such a manner that
simultaneously with the release of the driving and connecting clutch the brake blocks
are sprung into brake discs to absorb the stored up energy, all substantially as and
for the purpose hereinbefore described..
