KNITTING-MACHINE NEEDLE.

SPECIFICATION forming part of Letters Patent No. 387,507, dated August 7, 1888. Application filed January 16,1888. Serial No. 260,864. (No model.)

To all whom it may concern.-

Be it known that I, CARL FRESOHL, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Knitting-Machine Needles; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to those needles which are intended and adapted for use with that class of knitting-machines having needle'supporting cylinders, and the features which I believe to be new are hereinafter specifically claimed.

The object of my invention is to provide a needle with a spring to retain it in the groove of the cylinder and adapted for use with a short cylinder, as well as with a long one, which needle may also be readily inserted in or removed from the cylinder at the top.

- In the drawings, Figure 1 is a view of a knitting-machine-needle cylinder supported on its bed-piece and showing a needle in the position assumed in inserting or removing it from the cylinder. Fig. 2shows my improved form of needle. Figs. 3, 4, 5, and 6 are modified forms of the same needle.

The same letters refer to like parts in all the views.

In the drawings, A is the needle-cylinder of a knitting-machine, in each of the vertical grooves B of which is carried a verticallymoving needle, 0. These needles are retained in place by the walls of the grooves and by an elastic band, D, usually constructed of coiled wire placed about the cylinder in a groove near its top. The needles in common use in such machines all have a hook, E,.a latch, F, a shank, G, and a foot or bit, H. The cylinder is supported on a bed-piece, I.

To support and hold the needle in its groove against any improper motion up or down, I provide a spring, K, made integral with the lower part of the needle, but located above the foot or bit H, which spring is constructed of a strip or end of the metal, as

shown in Figs. 2, 3, 4, 5, and 6, adapted to bear against one side of the groove, as shown in Figs. 2 and 3, or against both sides of the groove, as shown in Fig. 5, or is constructed bifurcate, as shown in Fig. 4, adapted, to bear against both sides of the groove of the cylinder.

To provide a recess for the spring'K, the shank G is thrown forward at L, as shown in Fig. 2, whereby not only is the recess for the spring K formed in the shank of the needle, but at the same time this forwardly-thrown part of the shank becomes a guard for the spring, and also a guide on the needle, to hold the needle more certainly than would be done by the bit'aloue against turning or twisting in its groove. A similar forwardly-projecting guard and guide, L, is constructed in that form of needle shown in Fig. 6', in which the spring K is shown in front of the shank instead of in its rear, as seen in Fig. 2. The importance and desirableness of this peculiar construction of the needle will be seen when it is understood that in many knitting-machines now in use the cylinder A is so short and the bit of the needle in its travel in the groove goes'so near the bottom edge of the cylinder and to the bed-plate that a projection on the needle belowthe bit would not be practical; and the advantage of this form of construction will also be apparent when the usual method of inserting the needle in the cylinder beneath the retaining-band D is taken into consideration, which method of inserting the needle in the groove of the cylinder and beneath the band D is clearly shown in Fig. 1 at M, from which it will be seen that as the bit H and the shank of the needle are carried beneath the band D by an initial curvilinear motion it would be inconvenient and practically impossible to insert a needle beneath the band D from above in this manner if the needle were formed with any considerable projection below the bit H.

What I claim as new, and desire to secure ing a shank, G, a bit, H, and a spring, K, 10- cnted above the bit and adapted to bear laterally against the side or sides of the groove of the cylinder in which the needle travels, said shank, bit, and spring being formed integrally of a single piece of metal, substantially as described. I

In testimony whereof I affix my signature in presence of two witnesses.

CARL FRESCHL.
