Beit known that I, WILLIAM OsEoRNE, of

j Phnadeiphiaeouutyofrnnaceiphiaandstate `the accompanying drawings, which form part thereof. A

In the Kent and Leeson machine a blendingwheel is used to raise the plush-thread and pass it over the beards of the. needles, and thereby make it blend with thebinding-thread, which. is under the beards of said needles. In practice it is found that a difficulty arises, owing to the fact that at times the fabric having irregularities and lumps gets Within reach of the said blending-wheel and is caught thereby, which action bends and breaks the needles and stops the machine, and as there are usually a number of sets of the wheels shown in said patent used upon one large needle-head, the danger referred to isincreased proportionally.

The object of my invention is therefore to overcome this di'licnlty, and to accomplish this dispense with .the blending-wheel, and in place thereof II substitute a simple presserwheel of the usual construction, and on the inner side of the needlesl 'place a simple landing-wheel to Work in conjunction with said presser-wheel, and in place of using a single push-back I use two--one on each side of said landing-wheel-the object of which is to hold the fabric down upon the needles when laying in the plush and binding threads,`then`let it rise as the landing-wheel raises said fabric, and cause the plush-threads to pass up on the beardsV of the needles, and then the second push-back pushes the fabric down again, leaving the plush-thread over the beards and the binding-thread under the same, and after the fabric face-thread has been placed under the beards with the binding-thread the 'fabric is raised once again by the landing and knockover wheels used upon the machines generally,

and the old loops of the fabric and the binding-loops .pass over the tops of the needles, and the same operation takes place once more.

In the drawings, Figure l isa plan View of a part of a knitting-machine showing my improvement attached thereto. Fig. 2 is an elevation of Fig. l, with the wheels removed and the supporting-arms of the guides shown in section, the said gure showing the arrangement of the various threads on the needles in the process of knitting. Fig. 3 is a plan view of the plush-thread-introducing wheel; and Fig. 4 is a top view of a course of loops, showing the position of the plush-thread in the knitted web before it is carded.

A represents a portion of the inner stationary bed or frame of the machine, and A the outer stationary frame, to which the feedwheels, die., are secured. A

B represents a set of needles, of the kind commonly known as the "spring-bearded needle, which are secured in the ordinary manner in the revolving frame B', whiehlatter revolves in the direction indicated by the arrow, Fig. l.

'C is the looping-wheel, which places the knitting-thread upon the needles and under the beards oi' the same.

E is the dividing-wheel for forming the knitting-thread into loops or curves of equal size. l

F is the presser for closing the beards of the needles, while the loops forming the lower edge-of the knitted web rise over the same when released from the push-back S.

G is the landing-wheel, which raises the lower edge of the knitted web, whilethe presser F closes the beards of the needles.

G is the knocking-over wheel, which throws the loops forming the lower edge of the knitted web clear off the needles,I and thereby forms a new course.

The parts above described are of the kind heretofore used on circular-knitting machines having spring-needles, and are attached to the frame of the machine in the usual manner, be-

ing such as are used for making plain knitted fabrics from one thread 5 and, for the purpose of producing this kind of fabric, I use upon the machine, in addition to these, the parts hereinafterdescribednamely,aplush-threadlooping wheel, H, for introducing the plush- IOO \ plush-thread and fabric are raised, alandingn on the beards of the needles.

thread, a clearing-wheel, I, for pushing the l plush-thread down the needles, out of the way, while a binding-thread is being placed upon the needles, an additional looper, J, for introducing the binding-thread p, a presser-wheel, K'. to press in the beards of the needles as the wheel, K, for raising the said plush-thread and fabric, and a push-back, S', to force the fabric down again and leave the plush-thread n The push-back S holds down the fabric and 'allows it-to rise slowly after the binding-thread p has been introduced under the beards of the needles, the said fabric and. the plush and binding threads being raised by the landing-wheel K, and the plush-thread i, in the act of being raised, passes over the beards of the needles in front of which it is located, the said beards being pressed in by the pressure-wheel K', and the bindingthread p being under the beards of said nee- The fabric is then forced down again by the second push-bael ,S',leaVing the plushthread i in its new position, and the fabric or face thread d is then introduced under the beards of said needles, and a new row of loops of the fabric is formed by pushing said plushloops and the fabric loops over the tops of the needles, as set forth hereinafter.

The wheel H consists of a hub, e, a series of teeth or blades, f, which are set at an angle of about forty-five degrees (or other suitable angle) with the axis of the wheel, and which are formed with a nib, g, on the upper part of their edges, and a circular plate, h, having slots cut in its periphery, which is rigidly secured to the lower side of the wheel, which said slots are each opposite to two adjoining spaces between the teeth of the wheel, the other and intervening spaces being covered by the projecting pieces of the said plate, which said projecting pieces push every third needle inward as the frame B' revolves, and at the same time closethe beards of such needles. The teeth f are at a distance apart corresponding with the distance between the needles, and the nibs g seize the plush-thread as it is presented by the guide L and lay it over the needles, the projections of the plate 7L pushing inward every third needle, and at the same time closing its beard, so that the plush-thread is laid on the inside of two adjoining needles and on the outside of the next adjoining one, as shown at the right of Fig. 2, in which i represents the plush-thread. This wheel H rotates upon a pin or journal secured by any suitable means to the frame A' at such angle from the perpendicular as will enable it to lay the thread over theneedles in the manner indicated. The clearing-wheel I is somewhat similar in form to the wheels G and G', but works in the opposite direction, has bearings in an arm secured to the frame A', and is placed in such a position and at such angle that its teeth will work in between the needles in a downward direction. Its function is to force the plush-thread down the shanks of the needles,while the additional looper, J ,is placing the binding-thread pupon'the needles. The additional looper,J ,is similar inform and construction to the wheel C, and is set in a similar way.

It places the binding-thread p upon the needles in the same manner. that the wheel C places the knitting-thread upon f them,

rIhe presser-wheel K' and landing-wheel K fl are of the same construction as wheels F and G. The joint operation of these wheels, in 'f connection with the wheels C, E, F, G, and G' is as follows:

The plush-looper II takes the l yplush-thread i from the guide L, and places it' upon and between the needles in such a position that it passes over two or more adjoining needles on the inside of the circle of needles and over one needle on the outside alternately,

the slotted plate h closing the beards of the y n needles meantime, so that it shall pass over them. The clearing-wheel I lthen pushes the f thread z' downward, as seen at the right of Fig. 2, so that it shall not interfere with the action of the additional looper,J, which latter places Y t the second or binding thread, p, under the beards of the needles. As the plush-thread i is laid in the needles above the fabric, when the landing-wheel K raises the fabric it also raises the plush-thread, and after raising it sufficiently to p ut the said plush-thread i' upon the outside of the beards which lare held down by the presser-wheel K', the push-back S'pushes the fabric down and clears the needles for the reception of the fabric face-thread d. The wheel C then places the thread d upon the needles, the wheel E now equalizes the loop, the wheel G brings up the lower edge of the knitted web, (represented by the two parallel solid lines in Fig. 2,) while the presser F pushes back the beards of the needles. The wheel G' now the needles, while the threads p and d remain on the needles and now form the lower edge of the web. The plush-thread is thus laid in long loops on the back of the web, and is afterward subjected to the action of an ordinary card, to break the loops and bring out the plush in the ordinary manner.

The push-backs S S' may be made separately y or may be connected above the landing-wheel K, as desired,

I do not limit myself -to the exact construction of the push-backs and landing-wheel K, as they may be modified without departing from my invention.

Having now described my invention, what I claim as new is- 1. The combination of stationary frame, needle-cylinder, and needles, with the plush-looping wheel H, wheel J, presser-wheel K', landing-wheel K, push-backsS S', wheels F G G', and looping-wheel C, located on one side of said landing-wheel K, and wheels H and J on the other side, `substantially as and for the purpose specified.

2. The combination of stationary frame, neeing wheel H7, Wheels I and J, presser-Wheel .KQ landing-wheel K, push-back S, a' pushback,S, looping-Wheel G, and devices for rais- Y :ing the knittef web and throwing it off the ,i needles, substantially as and for the purpose specified. 4

3. The combination of stationary frame, needie-cylinder, and needles, with the plush-looping Wheel H, Wheels I and J, presser-wheel q K, landing-Wheel K, Wheels C E, presser F, g landing-wheel G, knock-over Wheel G', pushback S, and a push-back, S', substantially as v and .for the purpose speciiied. y

4. The combination of a stationary frame, needle-head, and needles, with loopingwheels the binding-thread, and the fabric facethread for inserting, respectively, the plush-thread, l

upon said needles, presser-wheel, landing and knock-over wheels, and devices, substantially as set forth, for raising` the fabric and' the plush-thread, for the purpose of placing said plush-thread upon the beards of the needles In testimony of which invention I hereunto set my hand.
