declare the nature of this invention to be as follows:-
The object of the present invention is to provide a shuttle sewing machine which
shall be of very simple and cheap construction and adapted to sew all sorts of cloth
including the coarsest leather and the finest silk, this great variability of work being
accomplished by means of the exceptionally manifold and variable adjustability of
the working parts.
The invention firstly consists in the general construction of the machine herein
after described and illustrated.
The attached drawing illustrates the construction of this sewing machine,
Fig. 1 being a longitudinal vertical elevation of the machine.
Fig. 2 a vertical transverse section on line ay Fig. 1.
Fig. 3 is a view of the opened needle actuating case.
Fig. 4 shows the gearing fitted in said needle actuating case.
Fig. 5 is a cross cut of the thread tensioning device.
Fig. 6 is a transverse plan view on line ¹ y Fig. 4.
Fig. 7 the same on line x2 y2 Fig 1.
Fig. 8 the same on line a y³ Fig. 1, and
Fig. 9 is a longitudinal section on line ay in Fig. 8.
This sewing machine is mounted with its work plate a upon a table in the
ordinary way and its gearing is actuated by pedals and the usual leather strap or
endless band which runs in the furrow b on the handwheel c.
The wheel c is provided with the usual coupling d. When this device is set as
shown in Fig. 1 the actuating band transmits movement directly to the cranked
main shaft in the horizontal arm of the machine which shaft when dismounted can
together with the front bearing y be pulled out after opening the needle actuating
'case A.
The lever i in Figs. 1 and 2 is mounted on the crank of the upper main shaft f
and sets the oscillating shaft j in motion, through the lever n with which it is con-
nected and which is fastened on the shaft j by a set screw m. The shaft is carried
in pivot bearings ll supported by the arms below the work plate a. From this
shaft is suspended a flat iron bands hinged on its upwardly curved ends o and p
the end o being lengthened so as to form a side loop and the end p shaped at its top
into a fork r (see Figs. 1 and 8). The iron bands is made to oscillate independent
of the shaft itself through the eccentric t on the main shaft and the eccentric rod u
Figs. 1 and 2 connected to the loop g.
j
This sewing machine sews with the ordinary double quilt stitch and works as
follows.
On the front end of the main shaft in the needle actuating case A, Figs. 1 and 3
is a crank disc v which carries the pin w engaging in the slot of the needle bar a¹
Figs. 1 and 4 and, by its rotation, pushes the needle up and down. At the same
time, the shuttle in the shuttle chamber C below the plate a is guided by the shuttle
carrier e through the cleft d' in the side wall c' and moved forwards and backwards
by the arm mounted on the shaft j as shown in Figs. I aud 7. The cloth feed gl
fixed before the second wall of the shuttle chamber pushes the cloth forward
after each finished stitch for the next for exactly the width of that stitch.
j
This pushing motion is imparted from the shaft and the iron bands to the said
cloth feed g' which rests upon the bent lever, the horizontal arm of which lever
is provided with forked ends and thus guided upon a fixed pin j¹ in the wall /', and

page_text: by a spring kits vertical arm is pressed tight against the cam on the shaftj while
a pivot m on the same end engages with the abovementioned fork of the iron
band s.
The oscillation of the fork imparts the sliding motion to the cloth feed g
as mentioned above and the sliding cam presses the feed tightly against the cloth
between the feed and the presser foot n' of the needle case see Fig. 4.
The upper
thread on the thread spool is carried over the tension device B to the hook q¹
Figs. 1 and 3 thence through the eyelet of the needle bar a¹ and finally through
an entirely hidden flap salong the front side of the needle actuating case A to the
needle .
The tension device B Figs. 1 and 5 is also of a novel construction and consists of
the small rotating wheels carried upon a pivot a drawn inward by the flat steel
spring t. The thread ' is held between these wheels and the more the screw w is
screwed against the spring the tighter the thread o is held by the discs or
wheels. An additional novelty is the spooling mechanism D, Fig. 1, namely
the actuating of the spooling device by pressure of the little wheel a thereof
against the endless band and transmission of the motive force of the latter to this
little wheel with the wedge shaped furrow . in this way actuating said spooling
device by the connecting endless band. This procedure does away with the
expensive fast wearing rubber rings hitherto used for the purpose.
Another novelty lies in the shuttle lifting device which throws out the shuttle
from the shuttle chamber C. This device consists of the adjusted wire e² shown in
Figs. 8 and 9 carried in the side wall of the shuttle chamber C and in a suitable
lug on the work plate a, said wire being held in position by a coiled spring das
shown in Figs. 8 and 9. When the needle is raised to the most elevated position
the shuttle is just above the hook shaped end 2 of the wire c² in the shuttle
chamber. If then the other end of the wire e² protruding above the work plate
is turned from right to left, the end e2 of the wire will fling out the shuttle at the
top opening of the shuttle chamber after the lock plate has been removed for the
purpose.
.

Further novelties lie in the stitch adjusting and the variable adjustment of
the presser foot n¹.
The diminishing or enlarging of the stitch is accomplished through shifting of
the eccentric rod in the loop 7 Figs. 1 and 2 by means of the bar or pusher h
fixable by the screw which catches the eccentric rod with the hook shaped end 2.
The largest stitch is secured when the bar is pushed in entirely, and the smallest
and narrowest in the reverse way.
The variation in adjusting the presser foot n' is effected by the screw Fig. 4
and its purpose is, when the efl'ectual pressure slackens through want of pressure
of the spiral spring upon the check or is otherwise required to be increased or
diminished, that the cheek may be moved and subsequently fixed with the screw, to
lessen or increase the pressure of the presser foot on the cloth.

I FRANZ BRETZ of Békés in the Kingdom of Hungary, Manufacturer 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:
The object of the present invention is to provide a shuttle sewing machine which
shall be of very simple and cheap construction and adapted to sew all sorts of cloth
including the coarsest leather and the finest silk this great variability of work being
accomplished by means of the exceptionally manifold and variable adjustability of

page_text: the machine hereinafter described and illustrated.
Reference being made to the drawings filed with the Provisional Specification
Fig. 1 is a longitudinal vertical section of the machine.
Fig. 2 a vertical transverse section on line y Fig. 1.
Fig. 3 is a view of the opened needle actuating case.
Fig. 4 shows, the gearing fitted in said needle actuating case.
Fig. 5 is a cross cut of the thread tensioning device.
Fig. 6 is a transverse plan view on line
y Fig..4.
Fig. 7 a transverse section on line 2 y2 Fig. 1.
Fig. 8 a similar section on line y³ Fig. 1 and
Fig. 9 is a longitudinal section on line at y', Fig. 8.
This sewing machine is mounted with its work plate a upon a table in the
ordinary way and its gearing is actuated by pedals and the usual leather strap or
endless band which runs in the furrow on the handwheel c.
The wheel c is pro-
vided with the usual coupling d. When the device is set as shown in Fig. 1 the
actuating band transmits movement directly to the cranked main shaft in the
horizontal arm of the machine which shaft when dismounted can together with
the front bearing a be pulled out after opening the needle actuating case A.
The lever i in Figs. 1 and 2 is mounted on the crank of the upper main shaft. F
and sets the oscillating shaft in motion through the lever n with which it is, con-
nected and which is fastened on the shaftj by the set screw m. The shaft jis
carried in pivot bearings supported by the arms below the work plate a.
From this shaft jis suspended a flat iron bands hinged on its upwardly curved
ends o and p the end o being lengthened so as to form a side loop 7 Fig. 2 and the
end p shaped at its top into a fork (see Figs. 1 and 8). The iron band s is made
to oscillate independent of the shaft ; and is driven from the shaft which is
connected to the loop 7 through the eccentric t on the main shaft and the eccentric
rod u Figs. 1 and 2.
At
This sewing machine sews with the ordinary double quilt stitch and works as
follows. On the front end of the main shaft in the needle actuating case A Figs. 1
and 3 is a crank disc v which carries the pin w engaging in the slot of the needle
bar a', Figs. 1 and 4 and pushes, by its rotation, the needle &' up and down.
the same time the shuttle in the shuttle chamber C below the plate a is guided by
the shuttle carrier e' through the cleft in the side wall cand moved forwards
and backwards by the arm f' mounted on the shaft ; as shown in Figs. 1 and 7.
The cloth feed gl placed before the second wall of the shuttle chamber pushes
the cloth forward after cach finished stitch for the next, for exactly the width of
that stitch. This pushing motion is imparted from the shaft j and the iron band s
to the said cloth feed g' which rests upon the bent lever the horizontal arm of
which lever is provided with forked ends and thus guided upon a fixed pin in the
wall hand by a spring its vertical arm is pressed tight against the cam on the
shaft while a pivot m' on the same end engages with the above mentioned fork r
of the iron band s. The oscillation of the fork imparts the sliding motion to the
cloth feed as mentioned above and the sliding cam presses the feed tightly
against the cloth between the feed and the presser foot n¹ of the needle case sec
Fig. 4. The upper thread o on the thread spool p' is carried over the tension
device B to the hook q' Figs. 1 and 3 thence through the eyelet of the needle
bar a' and finally through an entirely hidden flaps along the front side of the
needle actuating case A to the needle b'.
The tension device B Figs. 1 and 5 is also of a novel construction and consists
of the small rotating wheels v v carried upon a pivot u' drawn inward by the flat
steel spring. The thread o' is held between these wheels and the more the
screw is screwed against the spring the tighter the thread o' is held by the
discs or wheels v¹ v. An additional novelty is the spooling mechanism D, Fig. 1
namely the actuating of the spooling device by pressure of the little wheel a'
thereof against the endless band and transmission of the motive force of the latter

spooling device by the connecting endless band. This procedure does away with
the expensive fast wearing rubber rings hitherto used for the purpose.
novelty lies in the shuttle lifting device which throws out the shuttle from the
shuttle chamber c. This device consists of the adjusted wire c shown in Figs. 8
and 9, carried in the side wall of the shuttle chamber C and in a suitable lug 2
on the work plate a said wire being held in position by a coiled spring d² as shown
in Figs. 8 and 9. When the needle b' is raised to the most elevated position the
shuttle is just above the hook shaped end e² of the wire c² in the shuttle chamber.
If then the other end 2 of the wire c² protruding above the work plate a is turned
from right to left, the end e² of the wire will fling out the shuttle at the top opening
of the shuttle chamber after the work plate has been removed for the purpose.
Further novelties lie in the stitch adjusting and the variable adjustment of the
presser foot . The diminishing or enlarging of the stitch is accomplished through
shifting of the eccentric rod in the loop y Figs. 1 and 2 by means of the bar or
pusher fixable by the screw g² which catches the eccentric rod with the hook
shaped end. The largest stitch is secured when the bar is pushed in entirely and
the smallest and narrowest in the reverse way. The variation in adjusting the
presser foot is effected by the screw Fig. 4 and its purpose is when the effectual
pressure slackens through want of pressure of the spiral spring k² upon the check (2
or is otherwise required to be increased or diminished, the check may be moved and
subsequently fixed with the screw, to lessen or increase the pressure of the presser
foot on the cloth.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed 1 declare that what I
claim is.
1. In a double-quilt-stitch sewing machine the working parts a¹ bel g₁ actuated
by the parts hijf land tus pi¹ by the main shaft f together with the
cam g.
2. In a double-quilt-stitch sewing machine the tension device B, Figs. 1 to 5
