Application led March 30, 1918. Serial No. 225,754.

To all whom t may concern.'

Be it known that l, VVILsoN W. BUnsoN, u citizen of the United States, residing in Rockford, in the county of Winnebago and State of Illinois, have invented n new ond useful Improvement in Knitting-liliiohines, 0f which the following is n specification.

his invention relates in general lo kuit ting machines and hns for its object broadlyY the provision of u, knitting nnufhine ibut will knit n finer gauze gurmeut than has heretofore been possible in the machines prior to my invention,

Bly invention (contemplates the provision of n machine shorter reciproenting movements` and ur ranged closer together thun is possible with the latch needle, :ind has lalso for un objert the provision of n needle constructed for use in such n nmchine.

Another object of my invention is the vision of n knitting needle which will effectively with u short knitting stroke."

Another object of the invention is the provision of e knitting` needle constructed to require minimum space in the needle guides.

A other and highly importantobjeet of my invention is the provision of n knitting needle adapted to replace und perform all of the functions of the hitch needle, which Vro- Init

will operate automatienlhY in knitting and upon the mere forward projection und retraction of its knitting hook member.,

A still further object of the invention is the Vprovision of a needle which may be given e high degree of fineness nud et. the same time be strong and durable in use.

umerous other objects 4and ndvnntziges of the invention will he apparent es it is better understood from the following den Scription when considered in connection .with the accompanying drawing illustrating a preferred embodiment thereof.

On the dinwing,

The knitting hook meniber consists of a. sheet of metal folded bark upon itself at 15 und providing ui'iwiirdly extending spaced wings 1G :it the front and a hook 17 formed et the forward end oi the junction 15 between the silile portions of the member,A seid hook beim," thereafter bent up and over as indicated in Figs. l and The body of the knitting hook member extends rearwardly from the wings i6 und up into a. portion i8 edellted for engagement by the jack. A pom'ion I9 of it extends up and fornnrdlv forming n ruido for the tail of the lifting hook mem er. Rearwardly of a, point 2l e reinforcing plate is positioned between the ulnvzudlxv extending parts of the sheet of the knitting hook member and this member has the slnpe of the tail of the knitting hook member just described so that the reni.' part orteil .of the lm.tting hook member is of solid laminated member 14 is provided with nn enlarged forward end 23 adapted to be disposed between the wings 16 and having n bottom 24 adapted to rest 15 of the sheet forming the knitting hook the is cut away to provide a recess 25 efnin a lifting hook Q6 to be disposed just behin and'beneuth recesses 27 in thewfol ld edges of the Wings 16 in position to receive loop as the needle is projected'to pick u a. 28 isprovied 1x1 each wing `16 and alongside these slots uiper and 'lower lips 29 andl 31 extend out a the sides a, shortdistance and a similar lip 32 is provided on the upper edges of the construction.

wings in arallelism with the lips 29 and 31. The hea 23 of the lifting hook member is provided with two airs of oppositel; extending studs 33 andj 34, the studs .3i eing adapted to be disposed in the slots28 'and the studs 33 in position to nide upon the lips 32. From the head 23 'the lshank ofthe lifting hook member extends rearwardly and terminates in n return spring part 35 adapted to ress against the adjacent face of one partition 12 of the needle guide forcing the rear side of the shank against the other end creating sutiicient friction to cause the reletive movement of the needle parts as will be later described. `The shank is also provided at its end with bent-over curved lugs .S6-above the shank of the knitting hook member, andbeneath the forwardly extending part 1.9 so that this end of the knitting hook member is held to a, horizontal reciprocation. As the knitting hook moves from theI position shown in Fig. 2, in which position the parts are casting off the old loop over the new, to the position shown in Fig. l, which is the position the parts assume in the initial formation or' the new loop, the knitting hook is projectedby the jack and by reason of the friction between the lifting hook and the guides or partition 12 the forward niovement of the. lifting hook member is retarded until the studs 34 engage the lower rear ends'of the grooves 28 at which time the relative arrangement of the lit`ting'and knitting hook member is that shown in Fig` 1. At this time the knitting hook picks up the new yarn and the old loop has slid back into the recesses '27 and on to the lifting hook 26. Return movement of the knitting hook under the influence of the jack permits the rear end of -the lifting hook to remain stationery, the forward end rising as the studs 33 and 34 ride up the lips 31 and 32, the lifting hook 26 carrying with it the old loop and permitting it to drop oll' over the` knitting hook 17 and over the new loop c-(irried by it.

The' forward ends of the partition or guide 12 are rearwardly of the rearmost positions of the studs 33 ancLsl so that these studs may extend over the ends of the partitions end any unoccupied space between the needle guides, it only being necessary that snilicient space be there provided to permit the shank of the knitting hook member to move freely between the guides.

In order that the needles may more aecurately in their stroke, I provide an extension 38 on the needle bed, on which extension the lower feces of the knitting mein* 'bers slide. At the outer end this extension is provided with upwardly extending auxiliary guides 89 formed by sew-kerng a raised portion of the extension, or otherwise.

Since it is not necessary, as with the -over the ne latch needle,`to*r e member to be turned sufii cient f or the old loo to ass it, the stroke is meterielly reducedJin llngth being little greater than the distance between the knitting hook 17 und the liftin v' hook ZG when the parte are arran ed as s iown in Fig. 1. lt will be manifest rom the foregoing since the shank ot the knitting hook is constructed of three thicknesses of relatively thin sheet material, the space provided for them in the needle guides may be relatively narrow and the'number or' needles correspondingly increased in a needle bed of' riven dimensions. In making the knitting look member of sheet material and in reinforcing it as described it may be made of a high degree of fineness mid still have the requisite strength.

It is thought that the invention and meny of its attendant advantages will be understood from the foregoing description, and it will he apparent that various changes rney be made in the form, construction and are rangement of the parts without departing from the spirit and scop'e of the invention or sacrificing all of its material ad vantnges` the form hereinbetore desx'ribed beingmerely a preferred embodiment thereof. i
