3 Claims.

This invention relates to knitting machines with special reference to the verge plates used in connection with the sinkerhead or loop forming devices for straight line knitting machines.

Among the several objects the more important are: in reducing strain of the mechanism, preventing undue wear; avoiding jack, sinker and worn plate lines in the fabric; preventing uneven knitting, and effecting very considerable l0 saving of sinkers, time and material.

More specifically the purpose of the invention is in the provision of a, verge plate limitedly movable and resiliently pressed outward away from the sinker plate.

These objects are accomplished by the n ovel construction and arrangement of parts hereinafter described and illustrated in the accompanying drawings, constituting an essential component of this disclosure, and in which:-

l2l) Figure 1 is a top plan view of the sinker head of a conventional-type of knitting machine showing an embodiment of the invention in opera.- tive position.

Figure 2 is a plan view of the verge plate in detail.

Figure 3 is a similar view of the sinker plate.

Figure 4 is an edge view of undulating spring interposed between the verge and the sinker plates.

Figure 5 is a front elevational view of the same.

Figure 6 is an enlarged transverse sectional view taken on line G--B of Figure l.

Figure 7 is a similar sectional view taken on line 1--1 of Figure 1.

Figure 8 is a transverse sectional view of the loop forming portion of the knitting machine.

Figure 9 is a similar sectional view showing the same parts in advanced position.

4,0 Figure 10 is another like view of the same as further advanced.

Referring in further detail to the drawings, the machine will be seen to include a frame composed of a center bed I5 extending the length 4.3 of the machine; on the rear flanged portion of the bed is secured a jack bed I6, and on top of its upright forward portion is a base bar I1, its lateral edges extending both forwardly and rearwardly as shown.

The bar I'l is plurally grooved transversely to slidably receive dividers I8 alternating with sinkers I9, the upper edges of these elements being engaged in corresponding grooves in the cap bar 20 of the sinker head.

56 Raised lugs 2| on the dividers I8 are engaged in a catch bar 22 by an adjustable block 23 attached to cam actuated arms 24 moved rectilinearly by the machine elements. (Not shown).

Carried adjustably on the jack bed I6 are a series of spacer members or jack combs 25 held by a clamp bar 25 and spaced in conformity with the sinkers I9 whereby alinement is maintained.

A plurality of jacks 2l are pivoted on a rod 23 set in the spacers 25 and pressed forwardly by individual springs 29, their motion being limited by a stop bar 30.

The upper, forwardly curved ends of the jacks 21 are adapted to contact upstanding projections 3| at the rear ends of the sinkers I9.

A plurality of needles 32 are secured in a needle bar 33 held by a clamp 34 therein and actuated in a manner well known in the art.

'I'he improvements consist in a novel form of verge plate 35 loosely held on the inclined upper surface of the cap bar 20 of the sinker head and floatingly secured against rising by shoulder screws 35.

The verge plate is provided with substantially triangular openings 31 near its ends, through which extend pins 3Il xed in the cap bar 20.

'I'he rear edge 39 of the plate 35 is downwardly flanged and positioned in spaced relation to the rear edge of the cap; in the space thus formed is inserted a thin flat spring 40, bent sinuously to produce a series of undulations 4I, and its ends 42 turned angularly, its effect being to normally press the verge plate 35 rearwardly when it strikes the sinker projections 3|, cushioning the contact.

Thus the constant pounding of the sinkers is minimized, reducing wear and vibration and distributing the shock to the machine.

As changes of construction could be made within the scope of the invention, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent, isz- 1. In a knitting machine having a sinker head provided with a cap bar and a plurality of divider and sinker elements movable transversely in grooves therebetween, said sinkers having raised projections rearwardly of the cap bar, a verge bar floatingly secured on said cap bar, said plate having a. down-reaching flange entering the space between said b ar and projections, and a flat spring plurally undulated interposed between said flange and cap bar.

2. In a knitting machine having a sinker head provided with a cap bar and a plurality of divider and sinker elements movable transversely in grooves cooperatively formed therein, a verge plate having triangular openings, pins set into said head to extend into the mentioned openings limiting the movement oi said plate, means to prevent rising of said plate, a down-reaching ilange on said plate spaced from said cap, and resilient means disposed in the space therebetween to cushion the impact o! said sinkers.
