We, EDWARD MARSHALL, and GEORGE PHILLIPS, both of Birmingham, in the
County of Warwick, Machinists do hereby declare the nature of the said invention
for "NEW OR IMPROVED MEANS OR APPLIANCES IN COMBINATION OR CONNECTION
WITH SPRING POWER FOR DRIVING MACHINERY "to be as follows:-
Our invention has for its object simplifying the construction of apparatus used
in connection with spring power for driving machinery and consists firstly in
connecting together the desired number of coiled flat springs used according to the
power required in the following way-The outer end of the first of such springs is
secured to a suitable wheel or disc and the inner end of the said spring is secured
to a revolving arbor to which arbor we also secure the inner end of the second
spring--the arbor revolving on a solid bolt held in position through the sides of
the frame by nuts or other convenient means; the outer end of the second spring
is secured to the outer end of the third spring by a clamp or other suitable
arrangement and in like manner we continue to connect any desired number of
springs according to the power required.
Our invention relates secondly to improved means or appliances for utilizing,
controlling and connecting the power acquired by the winding up of such springs
with the machinery to be actuated and consists in placing a toothed wheel of any
suitable material upon an upright or horizontal spindle, the said wheel having a
revolving oscillating and up and down motion so that it can be brought and held
in gear to either a toothed wheel or cone by a suitable spring or traversing action
and in connection with the means here described we use the angular toothed wheel,
tangent worm or thread traversing stop arrangement described in our former
application for Letters Patent No 12,753 dated the 24th day of September 1884,
by which improved means or appliances and combination or connection with the
spring power before described we are enabled to give speed or power to the
machinery to be set in motion as circumstances may require.

We EDWARD MARSHALL and GEORGE PHILLIPS both of Birmingham in the
County of Warwick Machinists do hereby declare the nature of our said invention
for "NEW OR IMPROVED MEANS OR APPLIANCES IN COMBINATION OR CONNECTION
WITH SPRING POWER FOR DRIVING MACHINERY" and in what manner the samo
is to be performed to be particularly described and ascertained in and by tho
following statement :-
Our invention has for its object simplifying the construction of apparatus used
in connection with spring power for driving machinery and consists firstly in
connecting together the desired number of coiled flat springs used according to the
power required in the following way-The outer end of the first of such springs is
secured to a suitable wheel or disc and the inner end of the said spring is secured
to a revolving and by preference double arbor to which arbor wo also secure the
inner end of the second spring-the arbor revolving on a solid bolt held in position
through the sides of the frame by nuts or other convenient means; the outer end of
the second spring is secured to the outer end of the third spring by a clamp or
other suitable arrangement and in like manner we continue to connect any desired
number of springs according to the power required.
Our invention relates secondly to improved means or appliances for utilising
controlling and connecting the power acquired by the winding up of such springs
with the machinery to be actuated and consists in placing a toothed wheel of any
Buitable material upon an upright or horizontal spindle, the said wheel having a
revolving oscillating and up and down motion so that it can be brought and held
in gear to cither a toothed wheel or cono by a suitable spring or traversing action:
and in connection with the means here described we use the angular toothed wheel,
tangent worm or thread, traversing stop arrangement described in our former
application for Letters Patent No 12753-dated the 24th day of September 1884
by which improved means or appliances and combination or connection with the
spring power before described, we are enabled to give speed or power to the
machinery to be set in motion as circumstances may require-But as our invention
will be best understood by aid of the drawings hereunto annexed we will proceed
to describe the same reference being made to the figures and letters marked
thereon,
DESCRIPTION OF DRAWINGS.

page_text: their functions wero fully described in our former Patent N° 12753 dated the
24 September 1884.
The outer end of the spring H. is connected to the spur wheel E by means of
the clamp I. secured by the pins a. a. shown in dotted lines to the boss of the
same as seen at Figure 1. and the inner end of the said spring H is attached to
the double arbor shown in dotted lines marked J. and in a detached view at
Figure 5. by having a hole in the end of the spring and hooking the same on
to the projection K. as seen also in the detached view of the spring at Figure 6.
the end of the second spring His hooked to the other projection marked L.
on the arbor J. in the opposite direction to that of the first spring H. By this
arrangement (in the act of winding) the spring H. is made to wind the second,
third or any required number of springs in succession, thereby obtaining a direct
action from the springs H. H &c. to the tangent wheel A. A. and other parts
and also enabling us to dispense with drum chain and fusee referred to although
not claimed by us in our previous Patent before named-But in place of the said
fusce for the purpose of conveying controlling and regulating the power of the
springs to the machinery to be driven, we place the toothed cone M. figure 2. in the
most suitable position according to the description of machino to be driven-In
this case it is placed in a horizontal position and upon the shaft or spindle N. of the
sewing machine-but the position of this cone as boing the transmittor of the
driving power to the machinery will be varied according to the requirements or
description of machinery to be driven.
The necessary motion of driving the machinery attached to our new or improved
apparatus is obtained by means of the spring power attained by the winding up of
the springs by a handle being placed upon the spindle G figure 1. and turned in the
direction of the arrow until the traversing stop O. shown detached at Figure 7.
prevents further winding, by the projection b. coming in contact with the stop c. on
the winding spindle G. this is effected during the operation of winding by the cam
action on the outside of the revolving geneva stop wheel c. being in gear with the
rack d. on the traversing stop O. which moves the stop O. one tooth forward at
each revolution of the geneva stop wheel a. and which stop wheel c. makes ono
revolution only to twenty revolutions of the winding spindle G by means of the
single tooth E on the spindle G gearing into the edge of the geneva wheel C as seen
at figure 4-and when the springs are being wound up, the power is first conveyed
to the spur wheel E then through the spur pinion F to the tangent wheel A A and
then to the tangent worn or thread B, to which tangent or thread we attach a pair
of toothed wheels marked P the outer one being firmly secured to the tangent
worm or thread B while the inner one is held in position on the tangent worm or
thread by means of a flat spring pressing upon it and adjusted by a set screw or
lock nuts these wheels gear into the toothed cone M and as the action of winding
is continued the said wheels P advance up the toothed cone M by the action of the
cone on the geneva wheel C acting on the rack d of the stop O as previously
referred to until the winding up of the spring is completed when the wheels P on
the tangent worm or thread will be advanced into the position shown in a detached
side view of the stop arrangement and cone M at Figure 8 also expanding the
coiled spring R as shewn which spring assists the movement of the wheels P when
the apparatus is in operation until the power of the springs HH is exhausted
when the wheels PP will be in the position shown on the cone M and coiled
spring R closed or collapsed as seen at figures 1 and 2, by these means we regulato
and control the power accumulated and also regulate the speed of the machinery to
be driven.
When the winding is completed and the winding handle removed from the
spindle G the connection between the spur wheel E spur pinion F and the tangent
wheel AA is established by the pauls Q. Q. Q. Q gearing into the teeth of the
spur pinion F thus giving motion to the tangent worm or thread B and to.the
wheels P and cone M attached to the machinery to be driven in any convenient
position.

page_text: Having now described our Improvements and the manner in which the same
may be carried into effect we wish it understood that we do not purpose confining
ourselves to the exact details herein described and exhibited as they may be varied
to suit the different construction of machinery required to be driven but what we
claim and wish protected by Letters Patent is
Firstly: The means substantially as herein described and exhibited for con-
necting and controlling any required number of coiled springs to apparatus for
driving machinery.
Secondly. The controlling and equalising of the power of apparatus for driving
machinery. by means of the differential toothed cono M, toothed wheels P cam on
geneva stop wheel c, and rack d on stop O in combination with other parts
substantially as herein described and exhibited.
