lMPROVEMENT-lhi KNITTiNtQ MACHtNEtL Specification forming part of Letters Patent No. 1,540, dated February 9 1864 traction of the circular 'i'abric from-bending the needles, and interfering with the proper action of the said lifting-wheel;

In order to enable others skilled in the art to make and apply my invention, I will now proceed to describe its construction and operation. j v

0n referenceto the accompnn yin g drawings, which form a part of this specification, Figure 1 is a sectional elevation of sufiicient of a rotary knitting-machine to illustrate my in:

vention, and Fig. 2 a plan view. V The construction andoperation of knittingtnachines of the class to which my invention belongs are so well known that I have not deemed it needi'ul to illustrate or describe other parts than those to which my improvement directly relates.

A is the ordinary revolving cylinder, to which are secured the usual vertical needles a, and near the cylinder is a standard, B, car; tying. the usual lifting-wheel, or,as it is sometimes termed, the knocking-over wheel C.

Within the circle of needles a is a stationmy block, D, the top of which projects toward the liftiug-wheelG, forming a curved ledge extending above and nearly over the tops of the needles from the point so to the point m, Fig. 2. y

In ordinary knittingrnachines the circular fabric contracts the moment is lifted from the needles, and the stitches upon the needles are drawn inward against the latter with .such force that the needles arebeni, and considcrable resistance is made to the proper ac tion of the wheel 0 in raising the loop.

In order'to obviate these difficulties 1 use the above-described ledge b, which projects above and nearly over the needles at a point where the stitches escape from the same, so that the fabric 3 Fig. 1, instead of contracting immediately on leaving the needles, and thereby drawing the loops against them and interfering with the action of the lifting-wheeis,.

will not contract until. it has passed the ledge, thus obyiating the above-described difficulties. V

It is obvious thattwithout departing from the main ieatures of my invention a revolving wheel may be placed inside the circle of needles, instead of the block I) with itsledge or that a wire or plate of metal, presenting a curved edge, may be permanently secured and arranged so that it will extend between the points x and w, the effectbeing the same in both cases.

I claim as my invention and desire to secure by Letters Patent The block I) with projecting ledge '11. or their equivalents when arranged in respect to the needles and lifting-wheel of a rotary knitting-machine, substantially as and for the purpose herein set forth In testimony whereof I have signed my. name to this specification in the presence of two subscribing witnesses.

EDWARD snonn.
