Improvements in Sewing and Quilting Machinery for the Manufacture
of Quilts, Quilted Lining, Skirts, Mattresses, and other like
articles.
I, HARRY EDLER of Portland Street, Manchester in the County of Lancaster,
Manufacturer do hereby declare the nature of my said invention to be as follows:-
In the manufacture of quilts &c. I employ a multiple (by preference) lock-stitch
nachine with one two or more rows of needles of any number reaching across the
whole width of material to be sewn and arranged parallel with the feeding rollers
and in which the. needles presser bar and shuttle mechanism are moveable and
capable of travelling to and fro transversely across the width of the material in the
production of curves zig-zags and other fancy lines of stitching and which travelling.
parts may work in conjunction with one or more rows of stationary needles.
In order to impart the necessary reciprocating or traversing motion to the one
two or more rows of. needles on the same carriage a single grooved cam may, be
employed and by having a connecting rod to the other carriage (with one or more
rows of needles) I can operate the same and work the same figures of stitching but
in the opposite direction in case of some patterns however it is necessary to employ
a separate cam for each carriage.
On the driving shaft. of each carriage three or more cams are employed for
driving the needle bar or each needle may be similarly worked. by its own.
individual cam.
To run the mechanism of two carriages together I employ three spur wheels of
equal diameter and containing the same number of teeth but the middle spur
wheel must be of the sanse or of a greater: width than the widest pattern as the
outside spur wheels which are mounted upon the respective driving shafts of
the two machines traverse to and fro along its length in producing the pattern.
•
The shuttle mechanism consists of either one or more shuttles in one race or two.
or more right and left shuttles arranged parallel to each other in the same box
which races are so arranged upon pivots or vertical slides as to enable the operative
to withdraw any single shuttle from below the machine without interfering with
the material being sewn and whilst the machine is working.. Each shuttle is
operated from below by a slotted.arm mounted upon a vibrating shaft..
In case of several sets of needle bars the shafts of the same can be geared
together and driven by bevel gearing by cranks and connecting rod by pegged
chains and wheels or other equivalent.mechanism.
The carriages containing. the sewing mechanism are mounted upon rollers
anning parallel in the top surface of the table. A special grooved pattern cam

Improvements in Sewing and Quilting Machinery for the Manufacture
of Quilts, Quilted Lining, Skirts, Mattresses, and other like
articles.
I, HARRY EDLER of Portland Street, Manchester in the County of Lancaster,
Manufacturer do hereby declare the nature of the said invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
In the manufacture of quilts, quilted linings, skirts, mattresses, and other like
articles I employ one or more multiple by preference lock-stitch sewing-machines
each provided with one two or more rows of needles of any number reaching across
the whole width of the material to be sewn and arranged parallel with the feeding
or drawing rollers. The special feature in these machines is that the needles
presser-foot and shuttle-mechanism are so mounted in carriages as to be capable of
travelling to and fro transversely (more or less) across the width of the material
to be quilted and thus are used in the production of curves zig-zags and other
fancy lines. of stitching. The travelling machines may work in conjunction with
one or more rows of stationary needles producing straight lines of stitching.
On the accompanying drawing Fig. I is a side or longitudinal sectional view and
Fig. 2 a plan view of my improved multiple needle lock-stitch sewing-machine
shewn in conjunction with my improved feeding mechanism the subject of Letters
Patent No. 10223 granted to me on the 2nd day of July 1890 and of an application
for Letters Patent filed simultaneously herewith and numbered 2237 for feeding
the filling material between the two fabrics to be quilted.
As this feeding mechanism forms no part of the present application it will suffice
to say that the two fabrics to be sewn together are drawn off their respective
rolls 1 and 2 and the lower fabric 1 in passing backwards round the guide roller 3
receives the filling material from the revolving picker 4 and then carries the same
forwards beneath an adjustable roller or evener 5 for laying and regulating the
thickness of layer until it meets the upper fabric 2 passing round its guide
roller 6. The two fabrics carrying the filling material between them proceed in
the direction of the arrows around the several guide rollers and beneath the several
rows of needles of the sewing-mechanism and thus become sewn together with
continuous rows of fancy stitching as hereinafter described.
Fig. 3 represents the front or delivery end of the machine.
The sewing-mechanism I employ consists of one two or more needle-bars f
carrying rows of needles of any number reaching across the whole width of the
material and arranged parallel with the delivery rollers c'.
In Fig. 1 it will be observed that I illustrate the application of a single double
and treble row of needles.
Each needle bar f is provided with its presser-foot h (single double or treble as
the case may be) mounted upon rods e rising from the top of the needle-bar and
surrounded by spiral springs y to give the presser foot a constant tendency to
exercise pressure when the needles are in the material and the latter is not moving
but which presser-foot rises from such material along with the needle-bar when it is
travelling.
These
These needle-bars and presser-feet (along with the shuttle-mechanism hereinafter
described) are mounted in standards a and receive their vertically reciprocating
motion through links, as illustrated to several grooved cams e, e upon the driving
shaft d and which shaft has its bearings in the same standards a, a.
standards a, a are not stationary as usual but rise from a sliding base plate a¹
mounted upon rollers u running in guide grooves in the surface of the table a² and
thus constitute a carriage for traversing the sewing-mechanism to and fro
transversely across the machine.

page_text: It will now be apparent that by imparting the requisite to and fro motion to the
carriage as the fabric passes beneath the needles that any desired zig-zag curved or
other faucy lines of stitching can be produced. This is conveniently effected by
employing a single grooved pattern cam 6 shewn dotted in Fig. 2 (the groove of
which is formed in and around its periphery to correspond with the zig-zag curved
or other fancy lines of stitching required to be produced) mounted upon and
revolving with the shaft supported in brackets from the side frame of the
machine. A pin or stud 62 with a suitable bowl depending from the underside of
the travelling carriage and entering the groove of the cam serving to impart the
necessary to and fro motion to such carriage.
By means of a connecting yoke c at the extremity to accomodate the motion I
connect the two first carriages (single and double needle) together and so operate
the two by the use of one and the same cam and by which means I work the same
figure of stitching by each machine but in the opposite direction. In case of some
patterns however it is necessary to employ a separate cam for each carriage.
T
The drawing rollers c' are driven by the pawl c² and ratchet wheel from the
main driving shaft g through the eccentric This pawl and ratchet mechanism
also serves to drive the spur wheels c which in turn impart revolving motion to the
cam b.
On the driving shaft d of each carriage three or more cams e, e are employed for
driving the needle-bars f, for each needle may be similarly worked by its own
individual cam.
In order to drive the needle-bar and shuttle-mechanism of each carriage from
the main driving shaft g which revolves in stationary bearings g' I employ three
spur wheels, all of equal diameter as illustrated and each containing the same
number of teeth but the middle spur wheel i keyed upon the shaft g is of the same
or of a greater width than that of the widest pattern of stitch to be produced
whilst the outside spur wheels and j mounted upon the respective cam shafts d, d
of the two carriages are capable of traversing to and fro along its width without
becoming ungeared in producing the pattern.
In case of a single carriage as illustrated in the machine on the left hand side of
Fig. 1 of the drawing I only employ two spur wheels k, k the narrower one sliding in
the teeth of the wider one.
The shuttle mechanism (see Fig. 1) consists of either one or more shuttles
connected together and running in one common race or each shuttle may have a
distinct race m as illustrated and the races are so pivoted or hinged as to be capable
of turning down for taking out the shuttle or shuttles from below the machine
without interfering with the material. Each shuttle or series of shuttles is
operated by a slotted arm or picker n mounted upon a vibrating or rocking shaft o
receiving its motion from an eccentric o¹ on the cam shaft.
In case of several sets of multiple sewing-machines the driving shafts of the same
can be geared together as illustrated in the case of two separate machines in
Figs. 1 and 2 by means of cranks p and connecting rods 7 or by pegged or pitch
chains and wheels or other equivalent mechanism and between each machine I
prefer to form gaps or races by leading the material around suitable guide
rollers s and between which a platform t is formed to facilitate access to the several
needle bars f.
If I desire the carriages to be movable or stationary at every stitch according to
the pattern desired I employ a suitable cam with projections and corresponding
recesses formed upon its opposite sides working between a pair of friction rollers w, w
depending from the carriage as illustrated more clearly in Fig. 3 or I employ a
special grooved pattern cam (see Fig. 4) with steps and recesses in the groove to
form the pattern and so as not to move the carriage when the needles are sewing
but to move the same when the needles are out of the work and so on continuously.
The cam in this case being driven direct from the driving shaft of the machine.
Although I have only hereinbefore described my improved arrangement of
travelling carriage and cam driving mechanism as applied to a multiple needle

page_text: sewing-machine it will be apparent that they are equally applicable to a single
needle machine for producing fancy lines of stitching.
Having thus particularly described and ascertained the nature of this inven
tion and. in. what manner. the same is to be. performed I declare that what I
claim is
Ist. The combination and arrangement of parts constituting my improved
multiple needle lock-stitch sewing and quilting-machine substantially as herein-

rollers employed and mounted in a carriage capable of traversing. to and fro
transversely across the table of the machine substantially as hereinbefore described
and illustrated on the accompanying drawing.
3rd. In my improved multiple needle lock-stitch sewing and quilting-machine the
employment of pivoted or hinged shuttle races in conjunction with slotted pickers
operated by a vibrating shaft to allow of the shuttles being taken out from below
substantially as and for the purposes hereinbefore described and illustrated on the
accompanying drawing:
4th. The employment. of a grooved pattern cam driven by pawl and ratchet.
mechanism and toothed gearing and working in the case of a double machine in
conjunction with a suitable connecting yoke for operating the movable carriage or
