FULL FASHIONED KNITTING MACHINE Filed Jan. 16. 1930 lnueni'on 'fi g l zh// sbam wa Patented Mar. 29, 1932 UNITED STATES PATENT OFFICE .KENNETH HOWIE, OF NQRRISTOWN, PENNSYLVANIA, ASSIGNOIL TO WILDMAN MFG.

(10., OF NORRISTOWN, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA FULL FASHIONED KNITTING MACHINE Application filed January 16, 1930. Serial No. 421,175.

My present invention relates to improvements in full fashioned knitting machines, and more particularly it relates to an improved mounting for the knock-over bits.

An object of the invention is the provision of anarrangemcnt whereby the cuts or slots in the bar for receiving and supporting the knock-over bits may be made true and perpendicular in relation to the bar.-

A further object is the provision of a construction enabling the use of cutters of substantial width for forming the knock-over bit receiving slots, thus avoiding the use of very fine cutters which are liable to tip at an 5 angle and produce an angular cut resulting in an imperfectly set bit.

Another object is to provide a structure having relatively wide slots in the bar for receiving the knock-over bits, enabling the re-.

moval orcleaning out from said slots of any roughness or fins on the walls or bottom thereof which may have been left by the cutting operation.

A still further object is the provision of knock-over bit receiving slots of such width that each slot is adapted to receive two knockover bits separated by a spacer member, the entiredseries of knock-over bits being equally space Other objects will appear hereinafter from the accompanying description, claims, and drawings.

The invention consists in the'feat-ures, the

combination, and the arrangement of parts hereinafter described and particularly pointed out in the claims.

Referring to the drawings Figure 1 is a partly section view showing a cross-section of the bar and clamp with the knock-over bitand spacer shown in elevation.

Figure 2 is a plan view of Figure 1.

Fi ures

3 and 4 are elevations of the knockover it and spacer respectively.

Fi ure 5 is a perspective view of the spacer mem er.

In the drawings, 1 represents the bar in which are cut slots or kerfs 2 for receivingv the knock-over bits 3, said slots being. of such width, as shown bestin Figure 2, that each slot is adapted to receive a plurality of knock-- over bits. Two knock-over bits 3 are shown herein one against cash of the opposing walls of the slot 2, and with spacer member 4 therebetween.

The spacer members 4 are provided with vertical projections 4a like the projections 3a of the knock-overbits 3. These projections are adapted to be received in a groove 5 extending longitudinally of the bar 1, to maintain the knock-over bits and spacers in proper position.

According to the present invention the slots 2 are cutby cutters of substantial width (about 30 thousandths of an inch), as distinguished from the very fine cutters (about 4 thousandths of an inch) heretofore used to cut individual slots each for receiving a single knock-over bit, thus securing freedom from the danger attendant upon theuse of very fine cutters of deflecting of the cutter and producing an imperfect or inclined out not truly vertical. The use of the wider cut- 'ters according to the present disclosure produces slots of substantial width, ensures greater accuracy and results in the slots having perpendicular and parallel walls. The wide slots also permit of ready cleanin out of fins or projections within the slot le t by the cutting.

The spacer members 4 are equal in width to the intact or uncut portions of the bar between the slots, thus making the series of knock-over bits spaced apart equally. In other words the slots exceed in width the por- 35 tions of the bar between them, by the thickness of the two knock-over bits.

The usual clamp 6 bears at its forward edge upon the knock-over bits and at its rear edge upon the bar 1 at notch 1a, the clamp being adjustably secured to the bar by means of screw 7 having threaded engagement with said bar.

I claim:

1. In combination, knock-over bits, a bar having a series of integral parallel walls forming divisions between spaces at each side thereof, each of the series of spaces having therein a pair of knock-over bits, and stationary spacers inserted between the knock-over 100 bits, and s acing them apart distances equal to the thicliness of the integral walls against which the bits lie.

2. In combination, knock-over hits, a bar having a series of integral parallel walls forming divisions between spaces at each side thereof, each of the series of spaces being of a width to receive at least a pair of knockover bits with spacers between said bits, and stationary spacers inserted between the knock-over bits, and spacing them apart distances equal to the thickness of the integral walls, said walls segregating the bits with their spacers into groups, with the bits of each group and the groups themselves being equally spaced apart.

3. In combination, a bar having transversely extending kerfs in its upper face and a groove extending longitudinally of the bar across and below the bottoms of the kerfs and communicating therewith, knock-over bits and spacers inserted between the bits, each of which bits and spacers has a projection on its lower edge extending into said longitudinal groove, and a clamping plate secured to the bar and bearing on,the upper edges of the knock-over bits and spacers.

In testimony whereof, I affix my signature.

KENNETH HOWIE.
