I ARTHUR WILLIAM LOVELL REDDIE of the Office for Patents, 6 Bream's
Buildings, Chancery Lane in the County of Middlesex, Patent Agent do hereby
declare the nature of my invention for IMPROVEMENTS IN MACHINES FOR SEWING
AND QUILTING FABRICS BY MEANS OF PATTERN MECHANISM to be as follows:-
Although my Invention may be employed in machines for sewing and quilting
fabrics of various kinds it is more especially intended for producing upon fabrics of
large size such for example as bed quilts such as are known as "Comfortables" inade
by placing a lap or sheet of cotton or other filling between two sheets of woven
fabric patterns of quilting which are appropriate to the size and shape of the fabric
and particularly to produce such quilting automatically so that such fabrics may be
quilted in artistic and beautiful designs at small expense.
In carrying out my Invention I prefer to stretch or extend the fabric in or upon
a quilting frame or other suitable support or holder and I employ a sewing
machine having a long arm which will permit the needle to operate on any part
of the stretched or extended fabric.
In order to produce patterns by the sewing needle on the fabric it is essential:
that provision be afforded for a universal change in position between the fabric
and needle and that the speed of such universal and relative change in position
shall be at all times the same no matter what the direction of the lines along which
the change takes place.
To provide for such change in relative position between the fabric and needle
I mount either the sewing machine or fabric upon supports which are capable of
universal movement or in other words permit a universal movement of the sewing
machine or fabric These supports for the sewing machine or fabric may for
example consist of two carriages one mounted upon the other and capable of
movement in directions transverse to each other the first or lower carriage being
capable of free movement in order to permit a universal movement of the second
or upper carriage and the sewing machine or fabric which is supported thereon.
Now it is obvious that if a pattern board or plate having in or upon it a groove
or guide which is in form like the pattern to be produced on the fabric be arranged
in a plane parallel with the plane of movement of the carriages and sewing
machine or fabric holder and the second carriage or the sewing machine or
fabric holder (whichever is mounted thereon) be produced with a shaft pin or arm
:
•

page_text: engaging said groove or guide that the sewing machine or fabric holder may be
moved about and will be guided by the pattern in such manner that the lines of
sewing produced on the fabric will be made in the same form as the groove or
guide in the pattern and that such movement of the sewing machine or fabric
holder may be produced by hand if desired. (
Now in order to produce the movement of said carriages and sewing machine or
fabric-holder automatically I employ a pattern mechanism which forms a part of
the mechanical movement described in the Provisional Specification of Philip
Arthur Newton filed September 2nd 1884 Number 11,893 and which consists in
a spur toothed rack or other track arranged in pattern form and a positively
rotated pinion or other positively operating engaging device. If the rack or track
in pattern form be arranged adjacent to the aforesaid, groove or guide in pattern
form and the pinion or positively operating engaging device be carried by the said
second carriage or by the sewing machine or fabric holder mounted thereon then it
will be evident that the sewing machine or fabric holder will not only be guided by
the pattern but will be automatically moved along the pattern by the very
engagement of its pinion or positively operating device with the rack or track
of the pattern.
When the fabric holder is mounted upon supports which provide for its universal
movement under the needle of a stationary sewing machine the mechanism for
driving the needle operating shaft of the sewing machine may be of ordinary
character but when the sewing machine is mounted upon supports which provide
for its universal movement the mechanism for driving the needle operating shaft of
the sewing machine has to be of such nature as to operate during the bodily
movement of the sewing machine.
In a quilting machine in which the sewing machine is moveable the first or
lower carriage consists of an I-beam or stretcher mounted upon wheels at each end
and adapted to travel along tracks or ways. The second carriage consists of
frames attached rigidly to and depending from the sewing machine on opposite
sides of the beam or stretcher and provided with wheels or rollers for bearing on
the top and sides of and underneath the flanges of the I-beam or stretcher. These
side frames and rollers form a second or upper carriage capable of movement
lengthwise of the beam or stretcher and the rollers or wheels prevent the sewing
machine from canting sidewise.-The second carriage has upon it an upright shaft
which carries a pinion at its end and in a plane parallel with the plane of movement
of the sewing machine and preferably below the same is a pattern consisting of a
rack or track in pattern form with which the said pinion engages and by its positive
rotation in engagement with the rack or track it moves along the same
pattern is preferably formed with pairs of parallel flanges the rack or track being
formed upon one of them and the flanges being made to project beyond the rack or
track and on the stem, of the pinion is a loose friction roller which runs in the
groove or guide formed by the pair of flanges and so guides the sewing machine
and holds the pinion in engagement with the rack or track.
The
On the second carriage is mounted a cross shaft which drives the upright pinion
shaft through a screw and worm wheel and from this cross shaft motion is trans-
mitted by a belt and pulleys to a cross counter shaft supported by the sewing
machine and connected by a belt and pulleys with the needle operating shaft of the
sewing machine. The upright pinion shaft is made to slide vertically through the
worn wheel which drives it and it is surrounded by a sleeve to which is attached a
lever for raising the sleeve and shaft to lift the pinion on the shaft out of
engagement with the pattern rack or track.
A long driving drum or a driving shaft bearing a pulley moveable along it is
arranged parallel with the line of movement of the first carriage at one end thereof
and upon the opposite end of the first carriage is a pulley Upon the second
carriage are two pulleys one of which is on the aforesaid cross shaft and the other
of which ranges with the pulley on said cross shaft.-A long endless driving belt
band or chain passes around the driving drum or moveable pulley and around the

page_text: pulley on the first carriage and this belt or band is deflected around or over the
two pulleys on the second carriage and so drives the cross shaft on said second
carriage As the first carriage moves the driving belt band or chain travels along
the driving drum or the movable pulley which drives said belt travels along the
driving shaft and as the second carriage moves on the first carriage the pulleys
on the second carriage over which the belt or band passes or is deflected move
along the upper member of said belt or band while receiving motion therefrom.-
It will therefore be seen that during the bodily movements of the sewing machine
its cross shaft on the second carriage always receives rotary motion and transmits
that motion to the upright shaft and pinion which always rotate at uniform speed
and so the speed of movement of the sewing machine in any and every direction
will always be uniform.
The pattern whether consisting of a simple groove or guide in pattern form or of
a rack or track in similar form or of both a guide and rack or track may be
arranged to produce any desired figure or combination of figures upon the fabric.
Bed comfortables are commonly square or nearly so and hence an appropriate
design for such fabrics will be formed in whole or in part by lines of quilting
successively enclosing or surrounding each other or if figures are produced which
do not successively enclose or surround each other they will be arranged about the
common centre of the quilt.
To produce figures or designs having these characteristics I employ patterns
having grooves or guides in pattern form which successively enclose or surround
each other or which are arranged about a common centre.
"
A very beautiful and seemingly intricate design may often be produced by a
very simple figure produced or repeated in different positions on the quilt so as to
interlace itself and to this end I provide for turning the pattern or fabric one
relatively to the other so as to repeat one figure in as many different positions as
may be desired. The fabric may be turned relatively to the pattern or the pattern
or a part thereof may be turned relatively to the fabric.
In a quilting machine in which the fabric holder is movable it may be mounted
upon similar carriages and an endless belt and gearing employed as described for
operating the shaft on which is the pinion that engages with the pattern rack or
track. The sewing machine then being stationary may be operated by the ordinary
driving belt or mechanism.
Having thus generally described my Invention I will point out what I consider
to be the essential features thereof.
The Invention consists in the combination with a fabric holder and sewing
machine of supports for one of said parts consisting of two carriages mounted one
on the other and movable as described a pattern comprising a guide in pattern
form and a shaft or device on the second carriage engaging with said guide the
pattern being preferably arranged in a plane approximately parallel with the fabric.

I ARTHUR WILLIAM LOVELL REDDIE of the Office for Patents, 6 Bream's
Buildings, Chancery Lane in the County of Middlesex, Patent Agent 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
Although my invention may be employed in Machines for Sewing and Quilting
fabrics of various kinds it is more especially intended for producing upon fabrics
of large size, such for example as bed quilts such as are known as "comfortables
made by placing a lap or sheet of cotton or other filling between two sheets of

In carrying out my invention I prefer to stretch or extend the fabric in or upon
a quilting frame or other suitable support or holder and I employ a sewing machine
having a long arm which will perimit the needle to operate on any part of the
stretched or extended fabric.
In order to produce patterns by the sewing needle on the fabric it is essential
that provision be afforded for a universal change in position between the fabric
and needle and that the speed of such universal and relative change in position
shall be at all times the same, no matter what the direction of the lines along which
the change takes place.
To provide for such change in relative position between the fabric and needle
I mount either the sewing machine or fabric upon supports which are capable of

example consist of two carriages one mounted upon the other and capable of
movement in directions transverse to each other, the first or lower carriage being
capable of free movement in order to permit a universal movement of the second or
upper carriage and the sewing machine or fabric, which is supported thereon.
Now it is obvious that if a pattern board or plate having in or upon it a groove
or guide which is in form like the pattern to be produced on the fabric,.be
arranged in a plane paralled with the plane of movement of the carriages and
sewing machine or fabric holder and the second carriage or the sewing machine or
fabric holder whichever is mounted thereon, be produced with a shaft, pin, or arm
engaging said groove or guide, that the sewing machine or fabric holder may be.
moved about and will be guided by the pattern in such manner that the lines of
sewing produced on the fabric will be made in the same form as the groove or guide
in the pattern and that such movement of the sewing machine or fabric-holder may
be produced by hand if desired.
Now in order to produce the movement of said carriages and sewing machine or
fabric holder automatically I employ a pattern mechanism which forms a part of

page_text: the mechanical movement described in the specification of the patent of Philip
Arthur Newton dated September 2nd 1884 No 11893 and which consists in a spur
toothed rack or other track arranged in pattern form and a positively rotated
pinion or other positively operating engaging device. If the rack or track in
pattern form be arranged adjacent to the aforesaid groove or guide in pattern form
and the pinion or positively. operating engaging device be carried by the said
second carriage or by the sewing machine or fabric-holder mounted thereon then
it will be evident that the sewing machine or fabric holder will not only be guided
by the pattern but will be automatically moved along the pattern by the very
engagement of its pinion or positively operating device with the rack or track of
the pattern.
When the fabric holder is mounted upon supports which provide for its universal
movement under the needle of a stationary sewing machine the mechanism for
driving the needle-operating shaft of the sewing machine may be of ordinary
character; but when the sewing machine is mounted upon supports which provide
for its universal movement the mechanism for driving the needle operating shaft of
the sewing machine has to be of such nature as to operate during the bodily
movement of the sewing machine.
In a quilting machine in which the sewing machine is movable, the first or lower
carriage consists of an I-beam or stretcher mounted upon wheels at each end and
adapted to travel along tracks or ways. The second carriage consists of frames
attached rigidly to and depending from the sewing machine at opposite sides of the
beam or stretcher and provided with wheels or rollers for bearing on the top and
sides of and underneath the flanges of the I-beam or stretcher. These side frames
and rollers form a second or upper carriage capable of movement lengthwise of the
beam or stretcher and the rollers or wheels prevent the sewing machine from
canting sideways. The second carriage has upon it an upright shaft which carries
a pinion at its end and in a plane parallel with the plane of movement of the
sewing machine and preferably below the same is a pattern consisting of a rack or
track in pattern form with which the said pinion engages and by its positive
rotation in engagement with the rack or track it moves along the same. The
pattern is preferably formed with pairs of parallel flanges the rack or track being
formed upon one of them, and the flanges being made to project beyond the rack or
track, and on the stem of the pinion is a loose friction roller which runs in the
groove or guide formed by the pair of flanges and so guides the sewing machine
and holds the pinion in engagement with the rack or track.
On the second carriage is mounted a cross shaft which drives the upright-pinion.
shaft through a screw and worm wheel; and from this cross shaft motion is
transmitted by a belt and pulleys to a cross counter shaft supported by the sewing
machine and connected by a belt and pulleys with the needle operating shaft of the
sewing machine. The upright pinion shaft is made to slide vertically through the
worm wheel which drives it and it is surrounded by a sleeve to which is attached a
lever for raising the sleeve and shaft to lift the pinion on the shaft out of
engagement with the pattern rack or track.
A long driving drum or a driving shaft bearing a pulley movable along it, is
arranged parallel with the line of movement of the first carriage at one end thereof
and upon the opposite end of the first carriage is a pulley. Upon the second
carriage are two pulleys one of which is on the aforesaid cross-shaft and the other
of which ranges with the pulley on said cross shaft. A long endless driving belt
band or chain passes around the driving drum or movable pulley and around the
pulley on the first carriage, and this belt or band is deflected around or over the
two pulleys on the second carriage and so drives the cross shaft on said second
carriage As the first carriage moves, the driving belt, band or chain travels along
the driving drum or the movable pulley which drives said belt travels along the
driving shaft, and as the second carriage moves on the first carriage the pulleys on
the second carriage over which the belt or band passes or is deflected, move along
the upper member of said belt, or band while receiving motion therefrom. It will

page_text: therefor be seen that during the bodily movements of the sewing machine its cross
shaft. on the second carriage always receives rotary motion and transmits that
motion to the upright shaft and pinion which always rotate at uniform speed and
so the speed of movement of the sewing machine in any and every direction will
always be uniform.
.
The pattern whether consisting of a simple groove or guide in pattern form or of
a rack or track in similar form or of both a guide and rack or track may be
arranged to produce any desired figure, or combination of figures upon the fabric.
Bed comfortables are commonly square or nearly so and hence an appropriate
design for such fabrics will be formed in whole or in part by lines of quilting
successively enclosing or surrounding each other or if figures are produced which do
not successively enclose or surround each other they will be arranged about the
common centre of the quilt.
To produce figures or designs having the characteristics I employ patterns having
grooves or guides in pattern form which successively enclose or surround each other
or which are arranged about a common centre.
A very beautiful and seemingly intricate design may often be produced by a very
simple figure produced or repeated in different positions on the quilt so as to
interlace itself and to this end I provide for turning the pattern or fabric one
relatively to the other so as to repeat one figure in as many different positions as
may be desired. The fabric may be turned relatively to the pattern or the pattern
or a part thereof may be turned relatively to the fabric.
In a quilting machine in which the fabric holder is movable it may be mounted
upon similar carriages and an endless belt and gearing employed as described for
operating the shaft on which is the pinion that engages with the pattern rack or.
track. The sewing machine then being stationary may be operated by the ordinary
driving belt or mechanism.

the invention and in which the sewing machine is supported by carriages in such
manner that it is capable of universal movement; Fig. 2 is a plan thereof; Fig. 3
is a vertical section on the dotted line x, x, Fig. 1.; Fig. 4 is a diagram illustrating
a part of the means employed for transmitting movement to the operating shaft of
the sewing machine during its bodily movement; Fig. 5 is a detail sectional view
upon a larger scale, of a part of the mechanism shown in Fig. 3: Fig. 6 is a side

manner that it is capable of universal movement and Fig. 7 is a plan of the machine
shown in Fig. 6.
"
Similar letters of reference designate corresponding parts in all the Figures.
In both examples of my invention, the first or lower carriage, as here shown,
consists of a horizontal beam or stretcher A, furnished with brackets or lateral
projections A¹ As and provided with supporting wheels B B¹.
The two wheels B, at one end of said beam or stretcher are flanged and are
adapted to travel along a track or rail C; and a designates an arm projecting
downward from said carriage and engaging with a laterally extending lip or
flange a¹ on said rail. By these means the wheels B are guided on the rail C and
are prevented from rising therefrom. Near the other end of said beam or stretcher A
and journalled on the brackets A' are wheels B₁ which are adapted to travel or run.
along a track rail C¹. The rails C, C¹, extend parallel with each other and are at
right angles to the length of the beam or stretcher A. The beam or stretcher A may
advantageously consist of an I-beam of rolled iron made as light as is consistent
with the necessary strength and it may be strengthened by truss rods b as shown
in Fig. 1 to prevent deflection.
I will first describe the example of my invention which is shown in Figs. 1 to 5
inclusive. The sewing machine consists essentially of a long arm D through which
extends a shaft c for operating the needle bar d and another long arm D' to the
outer end of which, the work plate d' is attached as best shown in Fig. 1, 12
.::

page_text: : In connection with the needle I employ a looper, hook, or other stitch-forming
device, the shaft of which extends within the lower arm D', of the machine, and is
operated by a cam and rod or other ordinary connections from the operating
shaft c.
The connections for operating the shaft of the stitch-forming device from the
operating shaft, may be arranged in the hollow frame of the machine, as is
commonly done, and to operate both the needle and the stitch-forming device it is
only necessary to impart a rotary motion to the operating shaft c which I do by
means hereinafter described. .
Near the outer or front end of the long arm D' are bolted frames or
supports D3 D³ which depend or project downward on opposite sides of the
beam or stretcher A and in which is journalled a roller or wheel e bearing and
adapted to travel on the top of the said beam or stretcher A.
Near the rear or inner end of the long arm D' are bolted frames or supports D* D*
which depend or extend downward on opposite sides of the beam or stretcher A and
in which is journalled a roller or wheel e¹ which bears on the top of the beam or
stretcher A. The rollers or wheels e e' bear on the top of the beam or stretcher A,
near its opposite edges and are provided with flanges e which project, down on
opposite sides of the top flange f, of the beam or stretcher A and thus prevent
lateral displacement.
The frames or supports D³ D³ also carry guide rollers e³ which bear on opposite
edges of the lower flange f¹ of the beam or stretcher A, and thus prevent canting
or tilting of the sewing machine from side to side. The frames or supports D
carry rollers ewliich bear on the underside of the top flange f, of the beam or
stretcher A and thus prevent the sewing machine from rising.
From the above description it will be clear that the frames or supports D2, D3, D4,
with their wheels and rollers e, e¹, e³, es, constitute a second carriage, to which the
sewing machine D; D1, is secured and which is capable of movement in a direction
lengthwise of the beam or stretcher A while the first carriage, with the second
carriage and superposed sewing machine mounted upon it, is capable of movement
in the direction of the rails. C, C².
The construction of the two carriages hereinabove described, is very advantageous
both because of its strength and simplicity, and because of the very firm support
afforded the second carriage against canting or tilting from side to side and against
rising up.
I will now describe how motion is imparted to the operating shaft 'c of the sewing
machine.
Near the rail C is a long drum or cylinder E which is supported in stationary
bearings g and to which rotary motion is imparted by a belt driving onto a pulley g¹
at one end of the drum, as shown in Fig. 2.. This drum has a continuous rotary
motion and the first carriage moves above it in the direction of its length.
In lieu of the long cylindric drum E I may employ a shaft and a pulley locked
to turn with the shaft, but capable of sliding lengthwise thereof.
:
E designates a pulley journalled on a stud g2 projecting from the side of the
beam or stretcher A and adapted to rotate freely thereon. The pulley E¹ inoves
with the first carriage while the driving drum E does not; but the distance
between the centres of said pulley and drum is fixed and always remains the
same.
F designates a shaft which is journalled in the frames D2, D3 of the second
carriage and on which are fast and loose pulleys h, h¹, and ranging vertically with
said pulleys is an idler pulley h which is adapted to turn freely on a stud projecting
from the frame 1)².
1 1
G designates a belt which passes around the drum E and the pulley, E¹ and
which in its course partly encircles the pulleys-h h2 as best shown in Fig. 4. This
belt receives afcontinuous motion from the driving drum E. Its tension is preserved
at all times, because the distance between the drum and the pulley E' is invariable
and as it passes around the pulley h, it imparts. rotary motion to the cross shaft F.

page_text: When the first carriage moves on the rails C. C, the belt G. and the pulleys E¹,
h, h, hall move with the first and second carriages and the sewing machine, the
belt sliding along the drum E, lengthwise thereof; and as the second' carriage,
travels along the beam or stretcher A, the pulleys, h, h¹, h² move along the upper
portion of the belt G which encircles them. Consequently it will be seen that the
belt G imparts motion to the shaft F in whatsoever position the second carriage
and sewing machine inay be on the beam or stretcher A. The belt G is controlled
by a shipper rod h³ which extends transversely through the frames D*, D³, and is
attached to an arm projecting from a rock shaft h. The said shaft has .a
handle whereby it may be turned and by turning it the belt G will be shifted
from the fast pulley / onto the loose pulley h¹ and the shaft F will be stopped.
Upon the shaft F is a pulley i from which a belt passes to a pulley 2² on.a
shaft G¹ which is supported in bearings at the rear end of the sewing machine.
Upon the shaft G is a pulley from which a quarter-twist-belt drives onto a
pulley c¹ on the needle operating shaft c. By this mechanism the needle bar d is
operated from the shaft F during the bodily movement of the sewing machine,
and when the shaft F is stopped by shifting the belt G as described the bodily
movement of the sewing machine will cease, and motion will no longer be trans-
mitted to the needle bar d.
H designates a vertical shaft which carries at its upper end a worn wheel j and
on the cross shaft F is a worm or screw j¹ which gears into said wheel and imparts
rotary motion to said wheel and shaft H.
.
:
The manner of supporting the vertical shaft H is best shown in Fig. 5 but also
in Figs. 1, 2 and 3. The frame D³ is constructed with three bearings k k k and
the worm wheel j is held between the bearings kk. The upper portion of the
shaft H is grooved at as shown in Fig. 5 and the wheel j has a feather or key in
its bore which enters such groove. By such means the said shaft and wheel are
'locked together so that the wheel in turning turns the shaft and yet provision is
afforded for the shaft to move upward and downward through the wheel. The
portion of the shaft H which passes through the bearing ke is surrounded by a
sleeve which is arranged between a shoulder near the lower end of the shaft
and a collar fast on said shaft above the bearing k¹.
To the sleeve is connected a lever I fulcrummed at 13 and by manipulating this
lever the shaft H and sleeve may be raised for a purpose soon to be described.
When the lever I is in its upward position as shown in Fig. 1, its rear end may be
supported on a rest and its weight will thus be prevented from raising the
shatt H accidentally.
At the lower end-the shaft H is enlarged so as to form a socket 1 in which is
fitted a stem m¹ which projects upward from a pinion m and between it and the
end of the shaft H is a roller m² which is free to turn freely on the stem m³ and is
slightly larger in diameter than the pinion m.
The pattern employed consists essentially of a pattern board J, fixed in a
horizontal position below the carriages and having fast upon
it's
upper side or face
pairs of upwardly projecting flanges n n¹ (shown in Fig. 5) The distance between
the flanges of each pair is slightly greater than the diameter of the roller m² and
to the flange n is secured a rack 2 with which the pinion m is adapted to engage.
When the shaft H and pinion m are lowered as shown in the dotted portion of
Fig. 5 the pinion engages with the rack n² and by its rotary motion, will move the
shaft bodily along the rack, the carriages permitting the universal movement of
said shaft.
As before stated the roller m², is somewhat larger in diameter than the pinion!m,
and yet somewhat less in diameter than the space between the flanges n. n. The
roller will therefore.turn in one direction or the other, as it bears against.one.or
other of said flanges, and will at all times, keep the pinion from binding on said
flanges.
i
A
The pattern J which is here shown comprises several pairs of flanges n. n
extending round the pattern board, the flanges of each pair being separate and

page_text: "
distinct from those of the other pairs and surrounding or enclosing one another and
still other pairs of flanges which are arranged to produce a central figure, as seen
in Fig. 2. In order to remove the pinion m from engagement with the rack n² of
one pair of flanges, the shaft H and said pinion are raised as shown in Fig. 5 and
the carriages and sewing machine'may then be shifted by hand to bring the pinion
into position to be dropped between the flanges of another pair. Before thus
moving the shaft H, the shaft F is stopped and hence the pinion 'm is no longer
rotated.
^
From the foregoing description it will be understood that the pattern racks or
tracks are to correspond in form to the pattern to be produced, but the beauty
of the design may often be greatly enhanced by arranging a pattern portion of
very simple design so that it may be turned to produce the figure in different
positions on the fabric.' This is illustrated in Fig. 2 which shows a central circular
pattern portion J having a pair of flanges n. n¹ arranged to form an elongated
figure having a curved outline. After producing this figure in one position on the
fabric, the circular portion J¹ may be turned, and the figure again produced on the
fabric, and this may be repeated as many times as may be desired to produce
a foliated and seemingly intricate figure on the fabric. After being turned the
portion may be locked by a bolt r engaging one of several keepers 7.
K designates a rectangular fabric frame or holder to which the fabric may be
secured in a stretched and extended condition and in any suitable manner, as for
example, by tenter pins on said frame. The fabric frame or holder is supported by
standards K¹ and the fabric is removed so as not to hide the parts beneath.
Instead of turning the pattern the same result may be obtained by turning the
fabric frame K relatively to the pattern. Said frame may be lifted from its supports,
partly turned and replaced in a new position.
As the second carriage and sewing machine are moved universally by the
engagement of the pinion m with the rack n² the first carriage moves freely to
permit such movement and the needle of the sewing machine D D₁ will reproduce
on the fabric the design delineated on the pattern J. The rack n² constitutes the
pattern and the flanges n, n¹ constitute guides whereby the pinion wheel m is held
in engagement with the pattern rack n² The long drum E enables the belt G to
be moved along the drum lengthwise thereof.
As I have before stated the two parallel flanges n n¹ constitute a guide in
pattern form on the pattern J and broadly considered the shaft H is the device
through which the said guide controls the movement of the second carriage and
superposed sewing machine. The antifriction roller m² is the part which engages
directly with said guide, but both said roller and the pinion m may to a certain.
extent be considered as a part of the shaft H..
.
I will now describe the example of my invention shown in Figs. 6 and 7 and in
which the sewing machine is stationary and the fabric frame or holder universally
movable under control of a pattern J like that, before described.
The construction and arrangement of the lower carriage A, its supporting wheels
and tracks are all similar to that shown in Figs. 1 and 2. The sewing machine
which is stationary, has the upper and lower arms D, D¹, carrying respectively the
needle bar d and work plate d¹ and the operating shaft c is provided with a
pulley c¹ for a driving belt c*.
The fabric frame or holder K which is provided with tenter pins or other means
of securing the fabric at the edges, is, here movable and is constructed with cross
rails or stretchers K* which have depending from them, on opposite sides of the
beam or stretcher A frames D2, D3, D4, which carry an arrangement of guiding
wheels or rollers e, e', e³, e, similar to that before described for running upon the
beam A. The frames D2, D3, D4, with their rollers constitute the upper carriage
and the frames D2, D³, carry a cross, shaft F which through suitable gearing like
that before described, transmits motion to the vertical shaft H which engages with
the pattern J.

page_text: The arrangement of parts for imparting motion to the cross shaft F including
the belt G, drum E, pulley E¹, and pulley h, h1, h2, are all arranged as before
described and the construction and arrangement of parts for shifting the belt and
raising and lowering the shaft H are all the same as in Figs. 1 and 2.
;
In this latter example of my invention the fabric receives a universal motion
relatively to the needle of the stationary sewing machine, and the result produced
on the fabric is the same as in Figs. 1 and 2, where the fabric is stationary and..
the sewing machine movable.
In this example of my invention the pattern J, has no rotary centre piece Ji
like that before described, but has an arrangement' of flanges n, n¹, and racks n²
to produce a central foliated figure.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed as communicated to me by my.
