IMPROVEMENT IN KNITTING-MACHINE.

The Schedule referred to lnthese Letters Paten't ,and making part of the sama.

To all whom it may con-cern Be, it known Vthat I, HENRY ..'HOUSE, ot' Bridge` port, in the county of Fairfield, and State of Connecticut, have invented certain new and useful Improvements in KnittingMachinery; and l dohereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specication, in which- Figure 1,'shet 1,is a section through the machine, akenlin the horizontal plane indicated by line y in Figure 2, sheetlg'fis a longitudinal section through the machine, taken in the veltical plane indicated by line a: x in fig. 1.

.Figure 3, sheet 1,.-is -a Alongitudinal .sections-oi"theV frame,takeu in the saine plane as fig. 2, with the needlesand inner guide-plates or wallsV removed.

Figures 4 and 5, sheet 1,- are perspective views of needles and their toothed sections.

Figure 6, sheet 2, is an enlarged section, taken `transversely through the machine, as indicated by linezin'g. 1. p

This invention relates to certainnovel improvements onv thatclass of knitting-machinery which is adapted especially for knitting circular work, but which is applicable'to the production of straight or single work,

wherein the needles-are arranged'so as to travel aroundin'` the path of a' flattened ellipse, and alsorise and descend, for receiving the yarn and casting off 'the' loops. Y The nature of my invention consists in providing for Vincreasing Vor diminishing the capacity of a knittingmachneanda`ording guides-and `firm. supports for the needles at all times, by the employment of :tu extensible frame, constructed as will be hereinafterl explained.' I

'.lo ,enable others skilled iu the art to understand my invention, l'will describe its construction and operation. i

I have not represented' in the accompanying drawf ings,devices for supplying yarn to the needles and casting oi' the loops, for the reason that well-known devices, adapted for these purposes,may be employed. VA represents the main portion Of the frame of the 4machine, which portion consists of two parallel sides, l

terminatingin semicircular ends, one of which ends is cut away so as to lea.

1 tion, as shown in figs. 2-and 3.

Az represents thev'movable Vportion of the frame,v which is of a semicircular form, and tittedlsnuglypbetween the parallel sides of the .portion A, so as to be veonly a thin connecting por-` bridge-plate, H2., arranged beneath the baser-plate H1,

of .the section A2, this section can be rigidly secured to the portion A, at any desired distance from the closed end thereof.l

Within this extensible frame, plates g hh are ap- -:plied, so as to form a channel for receiving the toothed sections e of the needles e, and guiding these needles while in operation-.f -v

The plate or inner wall g is secured to the portion A, near its lower edge, and occupies about one-half the length`of this portion. I

i r1 he plate or wall h, which is semieircular,is secured to the movable section A?, at a point near its lower 4edge; and the' narrow plates h li extend from the vertical edges ofthe plate or wall 71., and are fitted' into grooves made in the outersurfaces of the straight portions of the walltg, so as -to be Hush with the said surfaces, as shown in iig'. 6..

.- y These narrow 'plates h-.h are connected to the wall y .g by screws t @which pass through long slots made through this wall, as shown in figs. 'l and 2,:at g'.

It will be seen, that the channel which is formed within the frame-sections A' A2, is endless, and of an equal width at-allpoints, and that this channel can "be lengthened or shortened by adjusting the 'section A2.

The 'base of this channel is `formed by the off-sets or ways p, on the inner surface of the section A, which should be straight, or parallel to the upper edges of this section, along those surfaces upon which the section Azis required-to slide; and at those points where the needles are required to take the yarn and cast oil' Vthe loops, the ways p should be formed as shown in gs. 2 and 3, so as to elevate theneedles as they successiyely pass around the closed end of the section A, and then allow them Ato descend or dip. i

It will be, seen, by reference to figs. 2 and 3, that Y "the ways p are carried around upon the inner side of the section A2, in an uninterrupted plane. l

Aboye the ways or shoulders p, is a groove, s, which is ,made in the inner. side of the section A, and continued around in the inner side of the adjustable sec?, tion A, above the ways .pi

I'Ihis groove s should be parallel to the Waysp, or equidistant from them at all points` throughout its length. i

At suitable points along the groove s, one or more switch-grooves, nl, lead fromit into a groove, n, from which 'one or more short vertical grooves, n2, lead ont to theupper edge of the scctionA', for allowing the insertion of the needles into their proper places, and a ready removal of vone or more'needles from the machine. l

Each one of the needles e is secured to a quill or toothed-rack section, el, which is adaptedto fit snugly but loosely into the channel formedin the'frame` above described, and which may be constructed with two or more teeth, according to the distance apart it is re-v quired to have the needles arranged in the frame.

Fig. 4 shows a needle, c, applied to a section, el, having three teeth; and iig. 5 shows a needle applied to a section having but two teeth.

These sections el collectively constitute an endless toothed rack, as shown in tig. 2, which rack is moved around in its channel by mea-ns of one or more toothed wheels C.

Each needle section el has a short, round stud, c2, extending from its toothed side, which is received by the groove s,.as shown in figs. 2 and 6, and .affords a support for the needles and their sections in this groove, so that while the needles will all slide freely, they, will be held down in their places, and be guided while-in operation by the groove s.

rlhe studs e2 may be formed by bending the buts of the needles at right angles to their shank portions, and passing these bent ends through I'the sections el, as shown in one instance in fig. 2; or the studs might be formed on the needle sections'in casting them.

To introduce the needles into the channel formed in frame A A2, the studs c2 must be inserted into a vertical groove, u, and made to follow the course of the grooves n nl, and the same movements are rcquired to remove the needles.

When the required number of needles have beenV inserted into theilv channel, as above stated, the sec-- tion A2 is pressed toward the closed end of section A, until all the quills or needle sections e2 are 'in close contact with one another. The section Az'is then se'f cured fast by its binding screw H, and the machine is ready for operation.

The spurred wheels C C,.which engage with the teeth of the needle sect-ions el, and move these sections around in their channel, are arranged near the .closed end of frame section A, on opposite sides theresot', and are keyed ou vertical shafts, 1) D, carrying spur-pinions c c.

The teeth o f the spurs c c are oblique, and engage surfaces of these sections, or they may be formed by a steel lining applied to said surfaces.

rlhe plate A1, which is secured to the bottom of 'frame section`A, beneath its chambered portion, will lserve as a bearing for the lower ends of the shafts I) 1), and also as a means for securing the machine to a table or other established object.

-I' am `aware that knitting-needles which were connected together by links have been applied to adjustable rollers or drums, applicable to chains of needles of different lengths; but I am not aware that an extensible frame, adapted for the working of disconnected needles, has ever been known or used prior to my invention. v

Having described my invention,

What I claim as new, and desire to secure by Let' ters Patent, s'- l 1. An extensible frame or needle-support, composed of sections A A2, having interior guides applied to them, and. adapted for receiving, supporting, and guiding knitting-needles which are disconnected from ,each other, substantially as described. 4

2. The plates or bars h1, in combination with the sliding vframe section A2, and inner walls g h, for connecting these walls and forming a continuation of the needle-guide channel between them, substantially as desciibed.
