F. J. FORD KNITTED PADDING March 18, 1941.

Filed 001;. 12, 1939 Patented-Mar. 18, 1941 UNITED STATES PATENT OFFICE 3 Claims.

fins invention relates to padding formed of fibrous roving. While capable of general application -my improved padding is particularly adapted for use in steam press apparatus for laundries or dry-cleaning establishments, and in fill lit

til

bit

tit

other similar machines.

it is the general object of my invention to provide a padding of improved construction, reduced cost and increased durability.

it further object is to provide a padding in which o. rope of loosely twisted rovings is incorporated as an inlay filler in a. knitted structure which possesses exceptional heat-conducting and heat-distributing qualifications, and in which structure the stretch in both directions is in the direction of the arrow '1 in Fig. 4.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

it. preferred form of the invention is shown in the drawing, in which Fig. l is a side elevation of a portion of a roving rope;

hie. 2 is a plan view of one form of my improved knitted padding;

big. it is a face view of a portion of the fabric;

t ig. t is a back view oil a portion of the fabric:

the. b an enlarged detail face view of a knitted structure;

file", t is a detail sectional view, taken along the line tti in. Fig. it; and

t is a detail inverted elevation, looking in the direction. of the arrow l in Fig. 4.

in the manufacture of my improved padding, i. start wlth usual textile fibers, such as shortiength cotton fibers, and first form the fibers into soft rovines ill. I then assemble a considerable number of the rovings ill in the form of a loose rope it, in which the rovings i extend lengthwise and substantially parallel and with slight twist.

ll then feed the rope R through a guide or condenser to a knitting machine, preferably of the circular type, and produce a knitted padding therefrom in which the rope R forms fillers or inlays which are firmly bound in place by a plurality of knitting threads. The slight twist in the rope R may be largely removed by the reverse twist feeding motion of the knitting machine.

Certain of these knitting threads, as 20, extend circumierentially of the fabric or lengthwise oi the ropes R at the face or the fabric, while other threads 2| extend transversely of the ropes (Cl. lid- 193) R which they firmly embrace. The threads 2| are interlooped with the circumferentially extending threads 20.

Additional threads 22 extend in general circumferentially to form a chain at the back of the 5 fabric and also pass through the fabric to the front side and are interlooped with certain of the circumferential threads 20. The threads 22 thereafter pass downward through the fabric and also shift longitudinally of the ropes R to loop into the next adjacent thread 22. The threads 22 thus provide oblique binders to additionally confine the rovings in the ropes R.

After the padding has been thus knit in the form of a tube, the tube is cut longitudinally to produce a broad fiat fabric. The knitting threads then extend transversely of the fabric or lengthwise of the ropes R and effectively limit transverse stretch. The knitting threads 2i and 22 permit a slight but definitely limited stretch my lengthwise of the fabric or crosswise of the ropes R.

I thus provide a padding formed from a soft rope comprising a plurality of loose rovings, but at the same time I provide a padding in which 25 stretch or sagging ls definitely restrained, so that the padding is well adapted for commercial purposes.

After the fabric is prepared as above described, it is out in the desired shapes and sizes and the go edges are bound in any suitable manner, as by stitching a tape '1 around the edge, or in some cases, the edge may be finished by overcasting.

When used in steam press apparatus, such as is found in laundries and dry-cleaning establishrnents, my improved padis found to distribute the heat of the steam very uniformly over an extended area. lit is also found that the pad does not as easily burn or char at the point where the steam is injected.

While these qualifications particularly adapt my improved pad for use where steam is injected, it may also be used for many other purposes, such as pads for athletic equipment, for upholstery, and in the manufacture of garments and 5 shoes.

it will be understood that the particular knitted structure shown may be substantially varied within the scope of my invention.

Having thus described my invention wild the ad- 60 vantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

l. n knitted padding comprising a succession of rope inlays, and a plurality of knitting threads interlaced with each other to confine said rope inlays and to definitely limit the stretch of the fabric, both longitudinally and transversely of said inlays, certain of said threads extending longitudinally of said inlays at the face of the fabric and crossing other threads with which they are interlooped, and certain of said latter threads forming chains extending transversely of said inlays at the back of said fabric.

2. A knitted padding comprising a succession of rope inlays, and a plurality of knitting threads interlaced with each other to confine said rope inlays and to definitely limit the stretch of the fabric, both longitudinally and transversely of said inlays, certain of said threads extending longitudinally of said inlays at the face of the fabric and crossing other threads with which they are interlooped, and certain of said latter threads forming chains extending transversely of said in lays at the back of said fabric and having inlayconflning portions extending both perpendicularly and also obliquely between said face and back.

3. A knitted padding comprising a succession of rope inlays, and a plurality of knitting threads interlaced with each other to confine said rope inlays and to definitely limit the stretch of the fabric, both longitudinally and transversely of said inlays, certain of said knitting threads extending longitudinally of said inlays at the face of the fabric and crossing other knitting threads with which they are interlooped, certain of said latter threads forming chains extending transversely of said inlays at the back of said fabric and having inlay-confining portions extending both perpendicularly and also obliquely between said face and back, and other of said latter knitting threads forming chains disposed transversely to said inlays and separately encircling and confining each inlay.
