COMPLETE SPECIFICATION.
An Additional Method of Giving Motion to Sewing Machines and
the like.
I, GEORGE GLASSON of The Excelsior Works, Agard Street, Derby in the
County of Derby, Carpenter & Joiner do hereby declare the nature of this inven-
tion 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 my invention is to provide an additional method of giving motion
to sewing machines and the like, the ordinary treadle being in some instances
very injurious to the operators, and persons of delicate health are often unable
to work them; the constant use too of a hand machine is extremely unpleasant to
some persons.
In carrying out my invention I employ a hand lever of iron, wood or other
suitable material attached to the machine by means of a hook, bolt, pin, rivet or
other suitable means. To this lever is or are attached one or more connecting
rods or chains of iron, steel or other suitable material, the said connecting rods
or chains are also attached to the treadle of the machine in any convenient and
suitable manner, or I may form a slot in the lever in which the crank of the
driving wheel may move freely backwards and forwards or a small connecting
rod acting upon the crank may be employed.
I may make the lever adjustable if desired by any suitable means such as by
thumb-screws or by having additional holes made therein. Although the lever
is here shewn fixed below the crank-axle it may be fixed above if desired or in
any other suitable position.
It will thus be seen that the lever motion may be used either independently
of the treadle or in combination therewith.
In order that my invention may be the more readily understood I have caused
to be annexed to this Specification a sheet of drawings to the figures and letters
of reference marked thereon I now refer, it being understood that the parts of
the sewing machine not necessary for the illustration of my invention are not
shewn thereon.
Figures 1 and 2 are side views shewing the hand lever A used in connection with
the treadle B, the connecting rod C being employed to effect the co-operation of
the two it is pivotted to the lever at M and to the treadle at N in any of the three
ways shewn on these two figures, the lever itself being pivotted to the frame of the
machine at E and operated by means of the handle F.
Figure 3 shews how the lever may be used independently of the treadle by
slotting the same as at G the crank or pivot E on the driving wheel D sliding in
the said slot.
Figure 4 also shews how the lever may be used independently of the treadle by
employing a short connecting rod H between the lever and the crank I.
Figure 5 shews connecting chains J instead of the rods.
Figure 6 shews how the lever may be hung to the frame or cross brace of
machine by means of a hook K, in this case two chains or rods L will be required.
O indicates the ordinary driving belt of the machine, P the machine spindle,
Qthe work table and R the ordinary connecting rod between the treadle and the
driving wheel.
A decided advantage is gained by employing a lever in that an assistant may
work the machine from the opposite side if desired; greater speed is also obtained
and it may be applied to any existing treadle machine.

page_text: 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:
An additional method of giving motion to sewing machines and the like, by
means of a hand lever, substantially as herein described and illustrated by the
accompanying sheet of drawings.
