I, DENIS FLANAGAN, of Wellfield Works, Clayton-le-Moors, in the County of
Lancaster, Machine Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in apparatus to be employed for driving
light running machines such as sewing machines, small lathes and the like
heretofore driven by hand or by foot power through the agency of treadles and levers
or wheels. The object of this invention is to enable the operator to drive a machine
or lathe at a high rate of speed with great facility and a minimum expenditure of
power, dispensing with the usual treadles, hand wheels, cranks, and the like.
According to this invention 1 employ a drum or pulley on the shaft of which is a
pinion wheel gearing into a wheel of larger diameter and carried loosely on a
second shaft on which is fixed a ratchet wheel the larger wheel engaging with the
teeth of the ratchet wheel and being thereby locked on the shaft when moving in
one direction, by means of a spring catch or pawl. On the same shaft as the second
wheel is a drum around which is a cord, strap, or wire which when pulled and
drawn off the drum the latter revolves and the ratchet wheel carries round with it
the gear wheel driving the pinion and the first drum or pulley from which motion
is communicated to the machine by strap or belt. A spring returns the drum when
the tension on the strap, wire, or cord is removed and so re-winds the latter that
the motion may be continued. The momentum causes the motion to be continuous
between the intermittent pulls on the cord or wire. The cord or wire is operated
by being connected to a stirrup or loop in which the foot of the operator is placed
or it may be connected to a rocking lever operated by foot or hand. The appliance
is fixed to the frame of the machine to be driven and is enclosed in a box or case..

Improvements in Driving Apparatus.
I, DENIS FLANAGAN, of 26, Oswald Street, Clayton-le-Moors, in the County of
Lancaster, Machine Maker, and also of Wellfield Works, Clayton-le-Moors afore-
said, 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 improvements in apparatus to be employed for driving
light running machines such as small lathes and the like heretofore driven by hand

page_text: or by foot power through the agency of treadles and levers or wheels. The object
of this invention is to enable the operator to drive a machine or lathe at a high rate
of speed with great facility and a minimum expenditure of power, dispensing with
the usual treadles, hand wheels, cranks, and the like.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which
Fig. 1 is a side elevation of the apparatus.
Fig. 2 is a cross section of same on line a, c, of Fig. 1 looking in the direction of
the arrow.
Fig. 3 is a plan of Fig. 1.
Fig. 4 is a cross section on line y, y, of Fig. 2.
In a suitable frame which may consist of side plates 1, 1ª separated by distance
pins 2 and suitably held together, is supported a spindle 3 such spindle being
capable of being withdrawn from one side and held in place by a screw 3" on the
other. Loosely mounted on the spindle is a pulley 4 which carries a band or
cord 4 which may pass to the part to be driven. In an open box or case 1' formed
on the side plate 1" is a spring 5 attached in some suitable way at one end to the
spindle 3 which it surrounds, and at the other to the plate 1ª as shown in Fig. 4.
Fixed on the spindle 3 is a pulley 6 with which is formed or which carries a
ratchet wheel 7. On the side of the pulley 4 is pivotally hung a pawl 8 which is
kept in engagement with the ratchet wheel 7 by a spring of some suitable kind.
As shewn in Fig. 1 a light blade spring 9 is employed fixed by a screw 10 carried
by the pulley, such spring bearing on the free end of the pawl 8. A strap 11 is
secured by one of its ends to the pulley 6 and is of sufficient length to coil or wrap
a few times on itself around the same, the other or free end carrying a handle or
stirrup 12 or other attachment of some suitable form for taking a pull or pressure.
The bracket is suitable secured to the machine or part to be driven, such as by
means of the lugs 1°, and by pulling on the strap which is normally kept coiled on
the pulley 6 by the action of the spring 5, the pulley is rotated, and by the
engagement of the ratchet 7 with the pawl 8, the pulley 4 is driven round. As
soon as the strap 11 has been pulled out to its limit it is released and the spring
will coil it up again, the pulley 4 continuing to run in the same direction by reason
of its momentum (the pawl 8 running freely over the ratchet wheel) until at the
next pull on the strap the ratchet is caused to overtake same and give it and the
pulley 4 a further impulse, the motion imparted to the pulley being practically
continuous.
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 :-
(1) The general construction, arrangement, and combination of parts constituting
the improved driving apparatus, as and for the purpose herein described, and
substantially as illustrated by Figs. 1 and 2 of the annexed drawings.
(2) The spindle 3, loose pulley 4, pulley 6, ratchet 7, pawl 8, spring 5, and the
strap 11, all in combination, as and for the purpose herein described and
substantially as illustrated by Figs. 1, 2, and 3 of the annexed drawings.
