. KNITTED PILE FABRIC l' Original Filed Feb. 16, 1938 2 Sheets-Sheet 2 IN VENTO R Harry Flejslzen BY ATTORNEY v Patented July 19, 193s KNITTED PILE FABRIC Harry Fleislier, Watertown, Conn., assignor to Princeton Inc., Watertown, Conn., a corporation of Connecticut Application February 16, 1938, Serial No. 190,763 Renewed June 21, 1938 s claims. (o1.- ca -191) This invention relates to knitted fabrics, and more particularly to a knitted pile fabric wherein the threads or yarns constituting the same are so arranged that the fabric is substantially runresisting and is provided, in addition to the regular plain stitch, with loops extending outwardly lfrom one surface forming a loop-pile which may be conveniently napped to give the fabric a woolly appearance. v

One object of this invention is to provide a fabric of the above nature wherein all of the pile loops are substantially the same in length and are firmly retained in the fabric.

Another object is' to provide a knitted pile fabric of the above nature having a new sequence of stitches including floats in'combination with pile-loops.

A further object is to provide a knitted pile fabric of the above nature having a ribbed surface formed by the pile loops and 4which, after napping, possesses a ribbed woolly appearance.

A still further object is to provide an improved knitted pile fabric of the above nature which will be simple and easy to manufacture, flexible and elastic, non-crushable, substantially run-resisting, and very efficient and durable in use.

With these and other objects in view, there has been illustrated on the accompanying drawings one form in which the invention may be conveniently embodied in practice.

In the drawings:

Fig. l represents a diagrammatic plan view of a circular eight-feed" knitting machine for producing the improved fabric.

Fig. 2 is an enlarged open view of the front surface of the improved knitted pile fabric embodying the principles and features of this invention.

Fig. 3 is a similar view of the reverse surface of the fabric.

Fig. 4 is a sectional view, taken on the line 4--4 of Fig. 2 through one of the courses of the fabric. t Fig. 5 isa sectional view, taken on the line 5-5 of Fig.2 through one of the wales of the fabric.

Fig. 6 is a development view of a portion of the needle actuating cylinder cam.

Fig. 7 is an enlarged vertical sectional view of a portion of the knitting machine. v 50 Fig. 8 is a sectional view of a portion of the needle actuating cam, taken on the line 8-8 of Fig. 6. l

Fig. 9 `is a sectional view of another portion of lthe needle actuating cam, taken on the line 9-9 I5 of Fig. 6.

Fig. 10 is a .detail view of the sinker used :in forming the fabric, as it appears `when engaging a single yarn for producing a. stitch, without forming a. pile-loop.

Fig. 11 is a detail View, similar to Fig. 10, showing the sinker as it appears when engaging two yarnsone for producing a knitting stitch, and the other 'for forming a pile-loop.

One important Vadvantage obtained by the novel arrangement of the threads o r yarns in the improved knitted pile fabric herein disclosed is that said fabric may be made on an ordinary plain knitting machine without employing complicated mechanisms or special attachments,1t merely being necessary to use a new form of sinker and a. 'suitable controlling cam therefor together with a needle-actuating cam cylinder arranged to produce oats at'certain desired points.

Referring now to the drawings, wherein like reference numerals denote corresponding parts throughout the several views, the numeral l0 indicates a circular stationary base or table upon which a plurality of upstanding brackets il are mounted. The brackets li support a stationary ring member l2, which carries a plurality of horizontal arcuate plates i3 forming a segmental l substantially circular sinker-operating cam mem- Provision is. also made ofv a rotating needlecarrying cylinder id and a. 'stationary annular needle-actuating cam cylinder l5, the latter being rigidly secured tothe stationary table lll in the usual manner and located below said stationary ring member l2. The rotary needle cylinder i4 carries a plurality of needles it and Il which are adapted to be engaged by the stationary needle cam cylinder I5 to cause said needles to travel upwardly and downwardly during the operation of the machine. The needles I6 are of the type having long butts, while the needles Hare ofl the type having short butts, and said long and short butt needles are arranged alternately around the circumference of the needle cylinder i4. Each of the needles lt'and I1 is provided at its upper end with the usual spring beard I8 which is adapted to catch the yarn on its downward stroke to form loops in carrying out the knitting action. Operating between the successive needles I 6 and Il are a series of horizontal sinkers i9, which are provided with substantially rectangular projections 20 on their upper edges adaptedto travel within a horizontal cam groove 2l formed in the sinker-operating arcuate plates i3. 'I'he cam groove 2l serves .to control 2. A knitted, pile fabric i'n accordance with claim 1', wherein the floats vare on the same side of the fabric as the pile-loops.

3. A knitted pile fabric in accordance with claim 1 wherein the threads forming the pileloops are interlocked between the adjacent knitted stitches and extend outwardly from the fabric on the same side thereof as the iioats are located. l y

4. A knitted pile fabric consisting of a repeat- Ving series of courses, each series including a first course havingv a single yarn knitted at even nurnbered wales and floated at odd numbered wales, a second course having two yarns, one being knitted at each wale and the other being forn1ed into a pile-loop, athird course having a single yarn knitted at odd numbered wales and iioated at even numbered wales, fourth and fifth courses y each having two yarns, one beingknitted at each wale of each course and the other being formed into a pi1eloop in each course, asixth course having a single yarn knitted at each wale, 4and seventh and eighth courses each having two.

yarns, one being knitted at eachJ-wale and the other being formed into a pile-loop at each wale of each course.

. 5. A knitted'pile fabric formed in accordance '7. A knitted pile fabric consisting of repeating v .2,194,861 3 series of courses, each series consisting of at least one course having iioats at every odd numbered wale, one course having fioats at every even numbered wale, a plurality of courses having pileloops extending outwardly from one surface of 5 the fabric, and a course without iioats or pileloops, said fabric being napped on the pile-loop side, whereby a wool-like loose fibrous effect is produced.

s. A knitted pue fabric consisting of a repat- 1o ing series of courses, each series including a. iirst course having a single yarn knitted at even numbered wales and floated at odd numbered wales, -a second course having two yarns, one being knitted at each Wale and the other being formed 15 into a pile-loop, a third course having a single thread knitted at odd numbered wales and floated at even numbered wales, fourth and iifth 4courses each having two yarns, one being knitted at each wale of each course and the other being formed 20 into a pile-loop in each course, a sixth course having a single yarn knitted at each wale, and seventh and" eighth courses each having two yarns, one being knitted at each Wale and the otherbeing formed'into apile-loop at each wale 25' of each course, said fabric being napped on the pile-'loop side, whereby a wool-like loose brous eect is produced. 9. A knitted pile/ fabric consisting of repeating series of cour, each series comprising a first course havingta yarn iioatedat every other, wale, a second succeeding course having pile `loops of a second yarn at every wale, a third succeeding course ha ng a third yarn oated at as every other wale and staggered from the oats of said rst course, and a fourth succeeding course having pile loops of a fourth yarn at every wale.
