DAVID HASTINGS HILL, OF PHILADELPHIA, PENNSYLVANIA.

CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 4"? 5,058, dated May 1'7, 1892.

Application filed December 30, 1891. Serial No. 416,585. (No model.)

To all whom it may concern.-

Be it known that I, DAVID HASTINGS HILL, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Circular- Knitting Machines, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in circular-knitting machines designed for making stockinette cloth; and it consists of aknitting-machine having extra knocking-over and clearing wheels, substantially as described, wherebya backin g-th read is secured to the fabric knit thereon by a tying-thread withoutthe latter being exposed on the face of said fabric.

Figure 1 represents a plan view of a circular-knitting machine, partly broken away, embodying my invention. Fig. 2 represents, as on a plane surface, a view showing the position of the needles and threads during the tying-in of the backing-thread. Fig. 3 represents a side view of a detail portion of the machine.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a circular-knitting machine adapted to make thereon stockinette cloth.

B designates a backingwheel adapted to depress a portion, of the needles 0, so that the backing-thread D fed to the machine is in front of some of the needles and behind the others.

E designates a clearing-wheel, which lowers the backing-thread D on the needles away from the beards C of the latter. wheel F forms loops on the light thread F fed to the needles and under the beards 0 thereof, the press-wheel G holding back the beards, so that the inside landingwheel I-I raises the thread D between the needles and outside or above the lower ends of the beards.

The parts so far described are old and well known and are not claimed per se.

J designates a knocking-over wheel of usual form adapted for raising the portion of the backing-thread D which is in front of a needle over and behind the same and over the The looptying-in thread, and K designates a clearingwheel of usual construction for lowering the thread, so that the entire thread D is placed behind the needles but in front of the tying in thread F, which latter is in front of the said needles, so that as the other threads L and M are fed to the needles by the loopwheels N and P and united with the stitches Q, already on the needles, by means of the operation of the dividing-wheel R, presser-' wheel S, and landing and knockingover wheels T and U, the said backing-thread D forms a backing for the cloth, the tying-in thread F not being exposed on the face thereof. The pushback V has a bridge or arched portion WV above the landing-wheel I-I, so as to permit the approach of the latter to the needles. Without the wheels J and K the tying-in thread would appear at intervals or at the points where the backing-thread would be in front of the needles, as at a, so that the face of the fabric wouldnot present a uniform appearance.

The mechanism, with the exception of the said Wheels J and K, is old and is not claimed per se.

Having thus described my invention, what claim as new, and desire to secure by Letters Patent, is

1. A circular-knitting machine for the purpose described, having the extra knockingover wheel J on the outside of the needlecylinder and the adjacent clearing-wheel K,

said parts being combined substantially as and for the purpose set forth.

2. In a circular-knitting machine, the combination of a rotary needle-cylinder with needles thereon, mechanism,substantially as described, consisting of backing, clearing, looppresser, and inside landing Wheels for placing a backing-thread behind some of said needles and in front of the others, and for placing a tying-in thread under the beards of said needles, an outside knockingover wheel for lifting the portion of the backingthread in front of the needle over the same and the tying-in thread, and a clearing-Wheel for lowering said threads on the said needles, said parts being combined substantially as described.

3. A circular-knitting machine having a sidelanding-wheelTand knocking-ever wheel needle-cylinderwithneedlesthereomthebaek- U, said parts being combined substantially 1o ing-wheel B, the clearing-wheel E, the loopas described.
