THE SUPPLY OF THE CLOTH
Year: 1885

page_text: 2nd THE SUPPLY OF THE CLOTH.
The feeding rod is fixed at the end i to d³ and makes a two and fro motion, and
which is used in different ways, instead of the motion of the real feeder or
pusher K. In Figs. 1 to 4 I is pressed upwards and sidewards with two sloped
noses and i and the spring at the end of I while in Figs. 5 and 6 the supply
rod I at the end of I possesses the fast and sloped projections and is as well as
the nose Fig. 7 moveable around I The pusher K has underneath a notch for
the bar I and the spring k.
The supply takes place as follows:-
When I goes from right to left K is raised by the the above projection Fig. 4,
21
or Fig. 5. sidewards by means of or 2, and the cloth carried along as far as I,
reaches the end of its motion On the return of I, K by means of the influence of
the spring K¹ goes downwards and the spring 3 brings in the arrangement shown
in Figs. 1 to 4 and pushes the feeder back till the pin N³, fastened to K rests
against the arm L' of the lever L used for altering the length of the stitch, and
80 K is held fast by L. By means of this arrangement the feeder K is always
pushed forwards to the same point and the length of the feed is detirmined by
means of the arms L.
By means of the arrangement Figs. 5 and 6 the pusher K is always pushed back
by the projection from behind on the bar I by the return of the same to the
same point and the length of the stitch is detirmined by means of the position of
the projection 8 The change of the same results from the Lever L used for
altering the length of the stitch Figs. 3 and 6 against the arm of which, the arm i
of rests and pushes out more or less towards the position L'. By means of this
arrangement the commencement of the supply of cloth is constant the end of the
same being detirmined by means of the length of the stitch.
3rd THE MOTION OF THE SHUTTLE
The lever M is fixed to the end d² and with this the lever N on which the
connecting rod P is placed with the shuttle case and with the fast turning-point
on the projections O of the frame of the machine. By the to and fro motion of d
(by means of the indirect connection of D with d) a stroke of the shuttle S. is
produced and also the necessary velocity of the shuttle S. suitable for the needle
and for a perfect lock stitch. At the head A' of the machine rests the thread
feeder which consists of the lever R Fig. 9 moveable on A' with the springs over
which the tension is laid and is placed moveable with R by means of the pivot r¹.
The link R³ connects R, and the needle rod H The thread coming from the spool Q
is laid in in the following manner, from the spool Q to R and R, and from thence
to the tension U.
As the tension R¹, by means of the spring, moves further away from R, so the
double length of the thread is looped By means of the connection of R and H the
play of the general thread lever, working on the unevenness of the stitches stops.
The automatic (by means of a spring) tension R₁ adjusts all unevenness of the
pressing of the cloth, and the thread material necessary for the formation of the
loop. In the needle rod H, the needle V. is fastened in the following manner :-
H has underneath it a hole h' Figs. 7 and 9 in which the piece h³ fits, and by
means of the screw h* is pressed against the needle lying in the groove ho. Thus V
is sure to come into its right position by means of h³ and by means of pressure
away from h, to keep it fast in it As figures 1 to 4 show the fore plate A³ is open
as far as the edge, and covered by a plate W In the same is situated on the left
side the pusher w Fig. 12 which for the purpose of taking out the shuttle and the
spool, is brought into the dotted position.
The guidance necessary is here given on one side by the straight edge a-b of
the fixed part W, on the other side by means of the rivetted angle w under W¹ to

page_text: which it is fastened and slides against the edge x of the frame plate, which is
always in the same place. The knee or angle joints have for their fast joining and
safe motion the arrangement shown in section in Fig. 2. one arm g is provided
with a projecting ring which lies in a groove of the other arm and thus supports
the middle pivot g³.
At the commencement it was shown that through the motion of the knee joint,
by means of the connecting rod every up and down motion of the same produces
two stitches in the machine without the application of wheels and belts. This
circumstance is independant of the means by which the middle joint d fixed to it
is moved to and fro and therefore in all machines, which by hand levers, treadle
apparatuses &c are directly or indirectly moved by the middle joint, there will be
a double stitch effected.
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
1st The application of an angle lever or knee lever by which, by a to and fro
motion of the middle joint, in consequence of the two sided stroke over the
stretched position of both joint arms, the machine makes two stitches.
2nd The feeder moved by a swinging lever I by whose upwards and sideward
slopes i and Fig. 1 or moveable projections and i the elevation and pushing
forward of the feeder K is effected by the forward motion of I; the depression
of K by means of the pressing spring Figs. 1 to 4 or the projection on the
return of S by which the length of the stitch is effected as in Figs. 1 to 4 by
the holding fast of the feeder or as in Figs. 5 and 6 by the holding fast of the
projection 26 on the side of the lever for detirmining the length of the stitch.
3rd The motion up or down of the needle rod H in a manner suitable for the
formation of the stitch by the to and fro motion of the knee joint G G¹ fixed to it
by means of a rod F which holds fast either both arms in the middle pivot g³ or in
one arm outside its fixed centre.
4th The guidance of the middle joint of the knee joint by a ring projecting from
one arm and lying in the recess of another.
5th The thread feeder K fastened to the needle rod H provided with a self
acting regulator tension spring R².
6. The fastening of the needle V by means of the piece ³ fitting into the
notch h of the needle rod H by means of the screw h in the groove h³.
7. The securing and guiding of the pusher W₁ in the plate W by means of the
angle w fastened under W¹ on the inner side of the base.
8. The hand sewing machine Fig. 1 to 4 by which the influence of a driving
crank on a knee joint D D¹ and the junction of the same with another angle or
knee joint G G¹ by means of the lever E and connecting rod F, causes a suitable
motion of the needle rod H. whilst the feeder I is moved directly from D D¹; on
the other hand the connecting rod P of the shuttle case Q is moved indirectly by
means of a lever N fastened moveably on the foundation and bound by means of
link M with the free end d' of the knee joint D D¹. By means of the knee joint
two stitches are made by the machine at every revolution of the wheel.
