Improvements in Two Reel Sewing Machines.
1, 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 sewing machines such as are described
in Specification of Letters Patent No. 2647 of the year 1892 granted to the present
applicant the object being to simplify the construction of such machines and to
lessen the liability of their getting out of order or being broken.
The invention consists of improvements in the reel case and carrier and appliances
connected therewith and also to improvements in the method of and means
employed for regulating the length of stitch by adjusting the feed motion.
According to this invention I employ a reel case carrier mounted on an arm free
to move on a pin or stud and held in position by an inclined spring locking pin.
Inside the carrier is the reel case containing the reel the top of such case being closed
by a cap or cover on the top of which is a projecting lug and the amount of
tension is regulated by a screw compressing a spiral spring which acts on the
tension block. When the reel case is placed in the carrier a cap or cover hinged
to the top of the latter is folded down and such cap or cover has a slit for the
passage
of the thread such slit being wide or open at one end so as to allow the
thread to quickly find its way into the slit. On the top of the cap or cover and on
each side of the thread slit are slight projections which when in position lie close
alongside a projection on the underside of the feed lock and the thread is guided
by these projections so as to be kept quite clear of the loop carrier when the machine
is in motion.
In its normal position the reel carrier is below the feed block and when it is
desired to place in position a new reel, or examine the reel case a slide plate on
the top of the bed is opened a lever moved and this lowers the spring locking pin
releasing the latter and at the same time acting on the incline of the pin forces
it to one side and a small spiral spring turns the reel carrier on its arm & movés
it below the open slide plate whereon the cap or cover of the carrier is by spring
in its hinge at once automatically opened and the reel case and its carrier is
exposed and open for any purpose and it is also clear of the loop carrier.
To replace the reel case and carrier in its working position the latter is slightly
thrown round on its stud by the finger and the underside of the bed plate acting
on the curved cap or cover of the reel carrier the latter is automatically closed
and when the whole has moved into correct position it is there locked by the
spring locking pin.
In order to allow the thread to pass freely between the reel case and the
interior of the carrier there is formed on the under part of the former two lugs
or projections and the loop carrier passes between these at each revolution and the
reel case is by the tension of the thread slightly raised from its seating in the
reel carrier and the thread passes freely between same.

moved and set in the slot of the link and forms a fulcrum pin for same and its
position regulates the length of stitch.

Improvements in Two Reel Sewing Machines.
1
I, DENIS FLANAGAN, of Willfield Works, Clayton-le-Moors, in the County of
Lancaster, Machine Maker, 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 sewing machines such as are described
in Specification of Letters Patent No. 2647 of the year 1892 granted to the present
applicant the object being to simplify the construction of such machines and to
lessen the liability of their getting out of order or being broken.
The invention consists of improvements in the reel case and carrier and appliances
connected therewith and also to improvements in the method of and means
employed for regulating the length of stitch by adjusting the feed motion.
Such being the nature and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings
in 'which
Figure 1 is a side elevation of part of a sewing machine with my improvements
applied thereto with the reel case removed.
Figure 2 is a plan view of the underside of a sewing machine with the improve-
ments applied thereto.
Figure 3 is an end view of Figure 2.
Figures 4, 5, 6, 7, 8 are details of the reel case and carrier.
According to this invention I employ a reel case carrier 1 mounted on an arm 2
free to move on a pin or stud 3 and held in position by an inclined spring locking
pin 4. Inside the carrier is the reel case 5 containing the reel the top of such case 5
being closed by a cap or cover 6 on the top of which is a projecting. lug 7 and
the amount of tension is regulated by a screw 8 compressing a spiral spring 9
which acts on the tension block 10. When the reel case 5 is placed in the
carrier a cap or cover 11 hinged to the top of the latter is folded down and such
cap or cover 11 has a slit 12 for the passage of the thread such slit being wide
or open at one end 13 so as to allow the thread to quickly find its way into the
slit 12. On the top of the cap or cover 11 and on each side of the thread slit 12
are slight projections 14 which when in position lie close alongside a projection en
the underside of the feed block 15 and the thread is guided by these projections 14
so as to be kept quite clear of the loop carrier 16 when the machine is in
motion.
In its normal position the reel carrier 1 is below the feed block 15 and when it is
desired to place in position a new reel or examine the reel case a slide plate on the
top of the bed 17 is opened a lever 18 moved and an inclined face of this lowers
the spring locking pin 4 releasing the latter and at the same time acting on the
incline of the pin forces it to one side and a small spiral spring 19 turns the reel

page_text: rrier 1 on its pivot 3 and moves it below the open slide plate whereon the cap
ver 11 of the carrier 1 is by spring 20 in its hinge at once automatically opened.
ad the reel case 5 and its carrier 1 is exposed and open for any purpose and it is
so clear of the loop carrier 16.
To replace the reel case 5 and carrier 1 in its working position the latter is
lightly thrown round on its stud 3 by the finger and the underside of the bed
late 17 acting on the curved top or cover of the reel carrier 1 the latter is
utomatically closed and when the whole has moved into correct position it is there
ocked by the spring locking pin 4.
In order to allow the thread to pass freely between the reel case 5 and the interior
of the carrier 1 there is formed on the underpart of the former two lugs or projec-
tions 23 and the loop carrier 16 passes between these at each revolution and
the reel case 5 is by the tension of the thread slightly raised from its seating
in the reel carrier 1 and the thread passes freely between same.
To regulate the length of stitch as desired the ordinary rocking shaft 24 of the
feed is connected by links 25 to the eccentric 26 on the main shaft 27 and in one
of the links 25 is a slot 28 receiving a roller 29 on one end of a rocking lever 30
on the opposite end of which is a roller 31 received in an incline or slot 32 on the
end of a lever 34 the position of which can be adjusted by set screw 35. By
moving the lever 34 the roller 29 is adjusted and set in the slot 28, of the link 25
and forms a fulcrum pin for the latter and its position regulates the amount of
movement of the following links and also the length of stitch.
Having now particularly described and ascertained the nature of my said
invention 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 reel case and carrier as and for the purpose herein described and
substantially as illustrated by Figures 1 and 2 and Sheet 2 of the annexed drawings.
(2) The general construction arrangement and combination of parts constituting
O the improved reel case carrier as and for the purpose herein described and
substantially as illustrated by Figs. 1, 2, 7 and 8 of the annexed drawings.
(3) The general construction arrangement and combination of parts constituting
the improved apparatus for regulating the length of stitch as herein described and
substantially as illustrated by Figures 1, 2 and 3 of the annexed drawings.
1 of July 1898.
