Complete Specification Left, 29th Sept., 1892-Accepted, 11th Feb., 1893
PROVISIONAL SPECIFICATION.
Improved Mechanism for Driving Sewing and other Machines by
Foot Power.
We GASTON HERVIEU of 73 Cambridge Road, Hammersmith Engineer and
NICOLAS ALPHONSE AUBERTIN of 10 Mornington Crescent Hampstead Road,
Chemist, both in the County of Middlesex, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to do away with the dead points which occur in
working sewing and other machines as at present constructed.
According to this invention we construct mechanism having a horizontal rotatory
motion instead of a vertical rotatory motion as heretofore.
One way of carrying our invention into effect is to fix the fly wheel horizontally
and to the crank thereof to fix a nearly vertical rod by means of an universal joint
and also to have another universal joint midway between the crank and lower end
of said rod so, that upon giving a horizontal circular motion to the lower end of
said rod it will rotate the fly wheel. The motion of the fly wheel arranged as
aforesaid may be imparted to the machine by any suitable means.

COMPLETE SPECIFICATION.
Improved Mechanism for Driving Sewing and other Machines by
Foot Power.
We GASTON HERVIEU of 73 Cambridge Road, Hammersmith, Engineer and
NICOLAS ALPHONSE AUBERTIN of 10 Mornington Crescent Hampstead Road,
Chemist, both 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:-
The object of this invention is to do away with the dead points which occur in
working sewing and other machines as at present constructed.
According to this invention we construct mechanism having a horizontal rotatory
motion instead of a vertical rotatory motion as heretofore. One way of carrying our
invention into effect is to fix the fly wheel horizontally and to the crank thereof to
fix a vertical rod by means of an universal joint and also to have another universal
joint midway between the crank and lower end of said rod so that upon giving a
horizontal circular motion to the lower end of said rod it will rotate the fly wheel.
The motion of the fly wheel arranged as aforesaid may be imparted to the machine
by any suitable means.
And in order that our said invention may be fully understood we will now
describe the same with reference to the accompanying drawings in which :-
Fig. 1. is a side elevation of our improved mechanism. Fig. 2. is a front
elevation of same. Fig. 3. is a top plan of same.
Similar letters of reference denote the same parts in all the views. a. is a crank
fixed to a vertical pivot b. so as to turn horizontally, c. is an arm fastened at its
upper end by a ball joint d. to the crank a. and its lower end is fastened rigidly to
another ball joint e. to which latter is also fixed rigidly an arm f. the lower end of
which is formed as at g. so that the foot may rest therein in order to work the
mashing

page_text: To the pivot . a fly wheel h. is fixed horizontally which also communicates
motion to the machine by the endless band o. (working in groove u. in fly wheel h.)
passing under pullies i. i. and over pulley p.
The pullies i. i. are mounted on arms j. j. and are supported by two brackets q. q.
jointed at l. 1. to pieces . r. which latter are also jointed to arms j. j. at . . so that
the pullies i. i. may be adjusted in order that the band o. may communicate with
the pulley p. in various directions these arms are also fixed to collars k. k. which
turn on the pivot b. in a horizontal radial direction so that the pullies i. i. may be
adjusted to suit the size and position of the pulley p. shewn more fully at Figs. 2
and 3. The whole is supported by a bracket m. in which the ball joint e. rests,
which bracket is fastened to a standard n. and a bracket t. fastened to top of
standard n. through which the pivot b. passes.
The action is as follows.
Upon circular motion being imparted to the arm f. by the foot at g. the fly
wheel h. will revolve horizontally and thus revolve the pullies i. i. and p. by
means of band o. The pulley p. is keyed on the driving spindle or shaft of the
machine which it is employed to work by our mechanism.
Although we have described the arm c. as fixed to ball joints d. and e. we do not
intend to limit ourselves to these joints as we may employ any other means for
obtaining the same result.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improved mechanism for working sewing and other machines by foot
power consisting of the horizontal circular motion substantially as hereinbefore
described and represented in the drawings.
2. The improved mechanism for working sewing and other machines by foot
power substantially as described and represented.
