SECTIONAL PLATING DEVICE FOR STRAIGHT-KNITTING MACHINES.

Specification ot Letters Patent.

Patented Feb. 27, 1912.

Application filed December 14, `1910. Serial No. 597,186.

.To all 'whom 'it may concern:

Be it known that I, PAULGUENTIIER, a citizen of the United States, residing at Dover, in the county otl Morris and State of New Jersey, have invented a new and Improved Sectional Plating Devic for Straight-Knitting Machines, ot which the following is a specification.

This invention relates to a straight knitting machine which is so constructed that selected portions of a stocking or other garment may be plated, while the remaining portions thereof may be formed of but a single thickness. It has more particularly been found desirable to provide the soles and heels of silk stockings with an exteriorly invisible interknitted lining thread, so to reinforce these parts, while the instep and the leg of the stocking is made of but a single thread.

My invention comprises novel and effective means for performing the plating operation and consists of the various features of construction more fully pointed in the appended claims.

In thc accompanying drawings: Figures 1, 2 and 3 are consecutive 'plans of the thread carrier sustaining bars' and coperating parts of my improved straight knitting machine; Figs. 4, and (l are front elevations of Figs. l, 2 and 3 respectively; Fig. 7 isn' sectional side view of one of the guides for the shogging bars' and the left tappet rod; Fig. 8 a sectional side vlewof one ot the guides t'or the shogging bars and the right tappet rod; Fig. S) an enlarged front View ot' one o't' the tappets; Fig. 10 a vertical cross section on line 10-10, Fig. 9; Fig. l1 a cross section on line 11--1i, Fig. el, showing the thread carriers; Fig. 1Q a sectional end view of one ot' thc friction boxes; Fig. 13 a sectional end view o'l one of the lixed stops and cooperating parts; Fig. 14 a front view of the stop; Fig. 15 illustrates the foot portion of an unlinished stocking knitted on the machine. and Fig. 1G shows a stocking length haring plated high heels.

The drawings illustrate only those vparts of a straight knitting machine ot the "lott0n type, which are pertinent to my invention, the parts omitted being of well known construction.

Throughout the length ot' the machine, extend a suitable number of preferably staggering shogging bars of which bars 20, 21,

22 only are used for carrying out my invention, while the additional bars shown in Figs. 7, 8 and 13 arc used for purposes foreign to this invention, liars Q0, 2l, are slidably supported by suitable spaced guides 23 forming part o t' the machine frame. Bar f2.0 is the main shogging bar and supports a plurality ot' main thread carriers Q4, while bara 21, 2L are auxiliary shogging bars and support. respectively a like number of au'xiliary thread carriers 25, 2G. Carriers 24 are adapted to travel across the entire width of the stocking or other fabric to be made and produce in conjunction with needles, sinkcrs and other well known elements of construction the meshes or loops 27 of the fabric. Carriers 25 are designed for lining or reinforcing the left` hand sole and heel portion Q8 oi: the stocking, while carriers 26 reinforce the right hand portion 29 thereof. After the tcet have been knitted down to inc 30 (Fig. '15), one set of auxiliary thread carriers is rendered inoperative, while the other auxiliary carriers travel across thc entire width of toe 31.

The movements ot' the main thread carriers and auxiliary thread carriers are so timed that the latter will lag for a uniform distance behind the former, thereby insur` ing a true plating as more fully brought out in Patent #878,724 granted to me February 11th, 1908.

Reciprocativc movement is imparted lto `bars 20, 9.1, Q2 by means of a shifter bar 32 mounted in standards :lil and axially reciln'ocated by well known mechanism (not. shown). Upon bar 32 is mounted a friction device or box 3-1- `which when unchecked participates in the movement of bar 3Q by lrictional contact. Upon a longitudinal spindlc 35 ot' box 34 is mounted an arm 36 which is adapted to engage the corresponding rec 37 of a lug 3S secured to bar Qt). The stroke o the latter is limited b v a pair of adjusting screwst) tapped into the usual left and right fashioning heads 4() ot the knitting machine.

Bar 21V receives reciprocative movement from shifter bar 32 by means ot' a parallel intermediary'tappet rod -ll arranged vertically above the lett hand portion ot' bar 2l and guided in hook-shaped keepers 4Q of guides 23. To rod 41 is secured, by screws 43 an L-shapcd tappct 44 the depending leg of which is received within a corresponding recess 45 of a lug 46 secured to bar 2l by multaneousl vibrating the entire machine frame in a ongitudinal direction. It is obvious that with 'prolonged use of the Inachine, the shogging bar guides wear out, so that the bars carrying the thread guides are more apt to become slightly rocked or jammed, especially if there is provided the usual close fit between said bars and the elements transmitting movement from the main shifter bar to the thread guide bars. By interposing between said bars my novel tappet rods, the transmission of any rocking impulses from the shifter bar to the thread guide bars is prevented, while owing to the slight play between the tappets and the recessed lugs of said thread guide bars the undesirable effect of rebounds is minimized.

I claim:

1. In a machine of the character described, a main shogging bar, a pair of auxiliary shogging bars, tappet rods operatively connected to the auxiliary shogging bars with freedom of movement relatively thereto, and means for reciprocating the main shogging bar and the tappet rods.

24. In a machine of the character described, a main shogging bar, an auxiliary shogging bar, a rod arranged in parallelism with said 'bai-s, a tappet on said rod, means for connecting the tappet to the auxiliary shogging bar with freedom of movement relatively thereto, means for connecting the rod to the main shogging bar, and means for reciprocating the main shogging bar.

3. In a machine of the characterdescribed, a main shogging bar, an auxiliary shogging bar, a recessed lug on the auxiliary shog ging bar, a rod, a tappet on said rod that is loosely received within the lllg1'ecess, means for cfmnecting the main shogging bar to the rod, and means for reciprmfating said main shogging bar.

4. In a machine of the character described, a shogging bar, a recessed lug secured thereto, a. rod extendingr in parallelism with said bar and located vertically thereabove, means for intermittently reciprocating said bar, and a tappet on said rod that is loosely received within the lug-recess, said recess being slightly larger than the tappet so that the latter has a play within the former.

5. In a machine of the character described, a shogging bar, a rod arranged in parallelism therewith, means for connecting the rod to the bar, said means permitting freedom of movement between said rod and bar, a pair of abutments on the rod, and a pair of reciprocative members adapted to engage the abutments.

6. In a machine of the character described, a shogging bar, a rod arranged above said bar, means for connecting the rod to the bar, said means permittingr freedom of movement between said rod and bar, a pair of abutments on the rod, a pair of reciprocative members adapted to engage the abutments, and stops for said members.

7.l Ina machine of the character described, a fashioning head, a stop carried thereby, a shogging bar adapted to engage said stop, an adjusting screw carried b the shogging bar, a removable stop adapter to be engaged by said screw, a tappet rod extending along part of the shogging bar, means for connecting said rod to said bar, with freedom of movement relatively thereto, and means for intermittent-ly reciprocating the tappet rod.

8. In a machine ot' the character described, a shogging bar, stops therefor, a rod extending along part of said bar, 4a tappet on said rod, a recessed lng on the shogging bar engaged by the tappet, abutments on said rod, arms adapted to engage the abntments, friction devices carrying said arms, 'and' stops for said devices.
