Application November 30, 1937, Serial No. 177,209 3 Claims. (C1. 86-110) 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. 5 Among the several objects the more important are: in reducing strain of the mechanism, pre venting undue wear; avoiding jack, sinker and worn plate lines in the fabric; preventing un even 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. 15 . » These objects are accomplished by the n_ovel construction and arrangement of parts herein after described and illustrated in the accom panying drawings, constituting an essential com l2l) ponent of this disclosure, and in which: Figure 1 is a top plan view of the sinker head (Not shown). Carried adjustably on the jack bed I6 are a series of spacer members or jack combs 25 held 5 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 lim 10 ited 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 nee 15 dle bar 33 held by a clamp 34 therein and actu ated 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 tive position. The verge plate is provided with substantially triangular openings 31 near its ends, through which extend pins >3Il ñxed in the cap bar 20. 'I'he rear edge 39 of the plate 35 is downwardly flanged and positioned in spaced relation to the is a plan view of the verge plate in is a similar view of the sinker plate. is an edge view of undulating spring between the verge and the sinker plates.

Figure 7 is a similar sectional view taken on 35 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 com posed 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. 50 linearly by the machine elements. of a conventional-type of knitting machine show ing an embodiment of the invention in opera.

Thus the constant pounding of the sinkers is minimized, reducing wear and vibration and dis tributing the shock to the machine. As changes of construction could be made with in the scope of the invention, it is intended that all matter contained in the foregoing descrip tion or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
