Improved Driving Gear for Churns.
GEORGE DUMARESQ of St. Marys Parish in the Island of Jersey 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 combination of levers by means of which a maximum
number of the muscles of the human anatomy together with the weight of the body
of the operator are utilized to produce power.
One application of such power is in the linear up and down motion used in
churning, and another is any rotary motion as upon a crank.
In the drawings:-
Figure 1, is a side elevation of a construction embodying the invention, and
Figure 2, shows certain additional details, not shown in Figure 1.
In the drawings:-
A, is a frame of wood, having base blocks a, a.
of it rise two uprights B, C.
From this frame, and as a part
D, is a seat upon which the operator sits to press one end of the lever E, by means
of the post d, made a part of the seat.
The lever E, is pivotally secured upon the centre e, its end farthest from the
contact point of the post d, being pivotally secured to the lever G, through the
centre, this centre being a steel rod of suitable dimensions and carrying at each end
the pedals F. The lever G, is pivotally secured to the upright B, through the
centre g, and its outer end is articulated to the link H, through the centre h. The
other end of the link H, is articulated to the lever I, through the centre ; the inner
end of the lover, being articulated to tho upright B, through the centre j, and its
outer end articulated to the handle k, of the churn K, through the centre 1.
The lever L, is made one with the lever G, and has handles M. In operating the
device; a person sitting on the seat D, and placing his feet on the pedals F, seizes
the handle M, with his hands; and by pulling with his hands and pushing with bis
foot, causes the churn dash to rise and fall while advantage is given him of the
weight of his body resting on the seat D, to give a very strong downward thrust to
the churn dash k.
In Figuro 2, the churn dash k, becomes a link to give rotary motion to a barrel
churn as shewn in that figure.
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 :-
1st. The combination with the frame A, having the upright C; of the seat D, and
the lever E, substantially as set forth.
2nd. The combination with the lever E, having the centre e; of the seat D,
having the post d, substantially as set forth.
3rd. The combination with the seat D, and the lever E, of the lever G, having the
podals F, substantially as described.
4th. The combination with the lever G, of the lever L, substantially as described.
5th. The combination with the lover G, having the pivot g, of the lever I, through
the link H, substantially as described.
6th. The combination with the lever I, of the link k, substantially
Rorine ads
as described,

page_text: 7th. The combination of the seat or member D, with the pedal F, and the
handles M, whereby through their articulated levers very great power is reproduced
through the muscles of the operator either in linear or rotary motion substantially as
hereinbefore described, and as and for the purposes set forth.
Dated this 3rd day of November 1896.
