IMPROVEMENT IN KNITTING-MAGHINE.
tite .clgettle nimm in in tijd trttrs tant Vrmt mating tutti its same.
TO .ALL WHOM IT MAY CONCERN:
Ba it known that I', ALF-RED JOHN Wann, of Philadelphia, Pennsylvania, havenvented an Improvement in Knittingdlachines; andI do hereby declare the following to b'e a full, clear, and exact description of the same.
My invention consists of certain thread-guides and cams arranged and operating as fully described here-` after, in connection with a circular-knitting machine, in which some of the needles project outward beyond the others, so that a supplementary thread or threads may be embedded in the fabric, to decrease its4 transverse elasticity and increase its density. l ,v
In order to enable othersfsklled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, whihh forms a. part of this specication, and in whichi Figure 1 is a sectional elevation of my improved knitting-machine, and
Figure 2 a plan view. y
A A are parallel stationary plates, through which ex tends a hollow cylinder, d3, having at the outside vertical grooves or channels, a, for the reception of needle-slides or bars, C, projections b on the latter extending between the opposite edges ot two annular cams or projections, D D', on the plates A". i
To some of the bars C are secured' needles c, and t'o others, needles c, the former being bent so as to be` almost in contact with the face of .the cylinder B, while the latter are bent outward, their upper ends being almost on a line with the outer edges of the bars C, to which they4 are attached, the two sets of needles alternating as shown-in the drawing.
To standards E,l on the plate A, are secured three' thread-guides, H H II, and to intermediate standards, E', are secured thread-guides F. Within the cylinder, at equal distances apart, are arranged three cams d d d, each of whiehis attached to or forms'a part'of a rod, G, secured to one of the standards E. I
A rotary motion in the direction of its arrow is imparted to the cylinder B, the cams DD being of such a shape, and thcguide and cams d being soarranged that each needle will begin to rise above the upper edge of the cylinder as'it passes from beneath either of the said guides F, and willdescend below the edge ofthe' cylinder immediately after passing from contact with the adjacent cam d. Y
These cams d aire of suoli -a l;orm that the needles c, as they are carried'past cach cam, are bent outward, until they occupy ,the same position as the needles c', and with the said needles will therefore catch the thread x, passing from'the guides H, and will carry the threads in loops through the'loops of fabric on the shaiiks of the needles in a manner too well known to those familiar with knitting-machinery to need particular description.
Asthe needles begin to rise, after passing from beneath the end of each guide F, a thread, y, will bedirected by the said guide tol such a point above the edge of the cylinder that each needle c will rise at the inside, and each needle c at the outside of the said thread, which is thus laid betwecii the two sets of needles, and is, consequently, intel-locked with the-loops ofthe fabric, and is embedded in the latter, although it is not itself formed v in-to loops. A i
The introduction of a thread in this manner, while it imparts density to the fabric, also limits its transverse elasticity. .'llie fabric thus approximates, both in its appearance and character, to loom-made goods, and when l Vfulled and shorn, cannot be readily distinguished therefrom, and it hasthe advantage over woven fabrics, as regards economy, by reason of the, greater rapidity and facility with which it can be manufactured.
Acylinder of any desired diameter, and carrying any gauge" of' needles, may be used to produce fabrics4 of any desired width andltextnre, while the number ot' thread-carriers or guides may bc increased or diminished as required.
I vclaim as'niy invention, and desire to secure by Letters Patcnt- M The cylinder B, with its'slides and its needles, some of which project outward beyond the others, in combination with supplementary thread-guides F and cams eZ, the wholebeing constructed, arrangedand operating substantially as and for the purpose described.
In testimonyjvhereot', I have signed my-nam'e to this specification in the presence of two subscribing witnesses.
i AFFRED JOHN WALE.
