their ratchets engage with pawls 16 pivoted on
thesidebars and thrown byany suitable spring
into mesh with the ratchets, a rubber elastic
band, 17, being a convenient device for the
5 purpose. The pay-off rolls 6 and 12, as well
as the take-up roll 9, are preferably square
or octagonal in cross-section. The quilting-
frame thus constructed is supported upon a
rail, 17a, transverse to the frame and arranged
ito beneath the stay-rod 3. This rail is provided
with a groove, 18, and bead 19, upon which
travel two wheels, 20, mounted on the stay-
rod 3. The rail 17" is clamped to the work-
table of a sewing-machine by means of any
15 suitable clamp and screw, 21, attachable to
the table. The ends of the rail which pro-
ject beyond the sides of the work-table of the
machine are supported by detachable legs 22,
connected to plates 23, screwed to the rail
20 and projecting beyond its longitudinal edges.
In the projecting ends of these plates 23 are
formed openings 24, and from each of these
openings a slot, 25, is cut to the outer edge,
the plane of said slot being inclined to the
z5 perpendicular at a suitable angle. Upon the
extremities of the legs are mounted headed
screw-eyes 26, which by inclining the leg may
be inserted in the slot and caused to enter the
opening 24, after which the leg will fall by
30 gravity into contact with the floor, where it
will support the rail and can only be removed
therefrom by inclining it sufficiently to en-
able the screw-eye 26 to pass out of 'the slot
25. By this construction the rail may be
35 moved without the legs dropping from their
attachment thereto.
The mode of operation is as follows: The
top and lining of the quilt are wound, respect-
ively, upon the pay-off rolls 6 and 12, andthe
40 ends of said fabrics are loosely stitched to a
cloth edge on the take-up roll 9, which may
be removed from its bearings for the purpose.
The take-up roll is then passed beneath the
guide-roll 8 and replaced in its bearings, the
45 lowerbearings, 10, being used forthe purpose,
in order to bring the fabrics down flat upon the
bed-plate of the sewing - machine. Before
mounting the take-up roll, however, the lin-
ing and top are separated to allow the intro-
50 duction of the batting, and after the roll is
placed in its bearings and the pawl engaged
with the ratchet 13, the pay-off roll 12 is
turned until the lining is drawn taut, the
ratchet 14 holding it, and any slack in the top
55 is taken up by revolving the roll 6, which is
placed in the uppermost of the bearings, 5".
When properly arranged the lining will pass
from the pay-off roll 12 under the roll 6, where
the top will be laid upon it, and both top and
6o lining will pass over the stay-rod 3 under one
guide-roll 8, and be received upon the under
side of the take-up roll 9. The frame is then
drawn toward the operator until the edge of
the goods is brought under the needle, where-
65 upon the machine is operated, the frame trav-
eling upon the rail 17 and producing a per-
fectly straight transverse seam. The threadsare then severed, and the ratchet i3 being re=
leased from its pawl the take-up roll is turned
a given distance to bring the succeeding por- 7c
tion of the fabric under the needle, whenthe
operations are repeated until it becomes nec-
essary to insert the batting. For this purpose
the pay-off roll 6 is removed from its bearings
and the top is removed from the lining as far 75
as the guide-roll 8. The batting is then laid
upon the lining and the top is replaced and
the pay-off roll mounted in its bearings, the
operation being repeated as often as may be
necessary. As the diameter of the take-up 80
roll 9 increases it may be shifted from the
lower bearings, 10, to those next above, and in
like manner the pay-off roll 6 may, as its di=
ameter decreases, be shifted from its upperto
a lower bearing in the lugs 5, the purpose be- 85
ing to maintain a surface contact between the
lining passing beneath the roll 6 and the top
wound on the latter, whereby the fabric form-
ing the top will be paid off and laid upon the
lining at the same speed with which the lat- 90
ter travels, thereby avoiding any fullness or
slack, and securing an equal tension upon
both fabrics, whereby the quilted material
will lie smooth and be free from folds and
wrinkles. The guide-roll 8 is also adjusted 95
vertically to correspond with the adjustment
of the take-up and retain that part of the quilt
lying on the bed-plate of the machine in a
proper position relatively to said bed-plate.
In withdrawing the top and lining from the roo
two pay-off rolls there is little difficulty in se-
curing an equal tension and travel of the two
webs. It frequently happens, however, that
it becomes necessary to draw. both fabrics
back upon the pay-off rolls. This may hap- o05
pen by the operator turning the take-up roll
too far to give an equal interval between the
seams, or it may result from other causes. In
all cases, however, the retrograde movement
of the pay-off roll 12 will produce an equal Ito
retrograde movement of the pay-off roll 6, or,
in other words, will cause both top and lining
to move backward to an equal degree, this re-
sult being produced by the surface contact
between the lining as it travels beneath the uT5
roll 6 and the top wound upon said roll. By
this arrangement I am able to produce a
similar and equal travel and tension of both
top and lining when moving in either direc-
tion, and I effect this result without gearing 20o
the two pay-off rolls together and by the op-
eration of one of said rolls only.
What I claim is-
1. A quilting attachment for sewing-ma-
chines, consisting of two side bars, a take-up 125
roll at one end, a stay-rod at or near the cen-
tral part thereof, a vertically-adjustable guide
and tension-roll revoluble between the stay-
rod and take-up roll, an independently revo-
luble pay-off roll for the lining at the op- 130
posite end of the side bars, a vertically-ad-
justable pay-off roll for the top removably
mounted in bearings between the side bars
adjacent to the stay-rod and between the lat-
