17 Claim;

This invention relates to improvements in knit-,

ting machines, and more especially to an improved adjustable stand assembly, for supporting thev various equipment such as burrs (sinker, clearing, backing, etc.), pressers and the like, which are commonly used in connection with circular spring needle knitting machines.

These knitting machines, as heretofore constructed, generally include a rotatable needle cylinder mounted upon a bed for rotation about a vertical axis. According to one well known type] of machine, there is attached to the bed of the machine, below the needle cylinder, a slotted Syracuse, N. I" a. corpora.-

the needle cylinder, and independently of each other and of the adjustment of the unitary assembly as a whole; A still further object of my invention is to provide a stand having one or more brackets adjustabiy attached thereto so as to allow adjusting movement of said brackets in one imaginary plane, and each of said brackets having another bracket 'adjustably attached thereto for adjusting movement in .another imaginary plane gen- ;erally perpendicular tothe, first plane, said last imentioned brackets each removably receiving and mounting ring which serves to support the usual stands and other equipment which are necessary for the feeding and manipulation of the thread,

pressing the needle beards, etc., as usually performed in the knitting of the fabric.

.behereinafter described,

supporting another stand, while permitting angular adjustment of said latter stand,

Other and further objects of the invention will and the novel features thereofdeflned by the appended claims.

For many years, it has been the practice with" such machines to employ a separate stand for practically each piece of equipment supported by the mounting ring, with the result that the equipj ment is-crowded together, making it exceedingly. difiicult to gain access to certain of the parts for.

purposes of adjustment as may be required from time to time. requires a greater length of time to set up, as well as to adjust the various individual parts for satisfactory performance of their respective functions and operations.- and the range of adjustment of the parts is at best very limited, and in some cases, nil.

With the foregoing in view, I have developed a new type of adjustable stand which facilitates and greatly simplifies the adjustment of-the usual equipment hereinbefore referred to, while at the same time being very compact so as to afford more room to permit the mounting of additional equipment about the needle cylinder when required, and affording convenient access to all of such equipment.

Another object of the invention is to provide a novel combination stand which embraces a plurality of stands or supports in a single unit;

capable of being attached to the usual slotted In addition, such an arrangement I mounting ring or other fixed support, by a single, 1 slotted link or equivalent connecting means pref erably permitting both circumferential and radial adjustment of the combination stand as a whole,

relative to the needle cylinder. v

My invention additionally contemplates as a further object, the provision of a unitary combi nation or multiple stand assembly, wherein certain of the individual stands, at least, are both laterally as well as'radially adjustable relative to for adjustablysupporting In-the drawings: t

Like reference characters designate corresponding parts in the several figures of the drawings wherein I generally denotes aconventional rotatable needle cylinder of a typical circular knitting machine, said needle cylinder having mounted thereon the usual ring of spring needles 2 which are attached thereto by the needle caps 3. As shown in Figures 1 and 2, the needle cylinder is disposed for rotation about a vertical axis, and it will be understood that it lies above the usual bed of the machine (not shown).

Such machines, of which the illustration herein is general, are sometimes provided with a slotted mounting ring 4 which is attached to the bed of the machine at a point below the needle cylinder as best shown in Figure 1. This mounting ring serves to support the stands and various equipment which are mounted about the needle cylinder for coaction with the needles in the performance of the knitting operations.

According to my new stand construction to which this application is primarily directed, I

, attach the stands to the slotted mounting ring A,

in single or multiple units as the case requires, said attachment being effected in the conventional manner by means of a slotted link 5 extending radially outwardly from the mounting ring 4 and adjustably secured theretoby a bolt fastener ii extending through the slot 1 in the mounting ring 4 and the slot 8 in the link 5. By loosening the bolt 6, the slotted link 5 can be adjusted both circumferentially as well as radially, relative to the mounting ring 4 and needle cylinder, as will be obvious.

As shown in Figures 1 to 4, my new stand assembly includes a main stand 9 which is adapted to rest upon the upper side of the slotted link 5, the lower end of the stand being preferably milled flat to seat upon the slotted link without rocking. Attachment of the stand 9 to the slotted link 5 is preferably accomplished by means of a bolt Ill passing through the slot 8 of the link 5, into the lower end of the stand which -is provided with a threaded aperture to threadedly receive the bolt I0. By loosening the bolt ill, the stand 9 may be adjusted longitudinally along the slotted link 5, that is, radially respecting the needle cylinder, independently of the radial adjustment afforded by adjusting the link 5 itself on the mounting ring 4 as previously described. In the construction shown in Figures 1 to 4, the stand 9 extends upwardly to a point in the zone of elevation of the needle cylinder above the bed of the, knitting machine, and the upper end of the stand is forked or bifurcated to provide a pair of laterally spaced vertical arms H, 7

ll. Each of the arms H, H is preferably provided on its inner face with a shoulder i2 extending vertically thereof, for cooperation with a guide l3 provided on the inner face of a depending bracket l4 forming a part of the piece of equipment which is to be mounted on the such as a sinker tube assembly l5. The guide I3 is of such width as to lie between the forked arms H, H of the stand 9, but affording sliding engagement therewith to permit vertical adjustment of the bracket i l relative to the stand 9. A bolt l6 extending through the bracket I4,

and having an enlarged head l1. spanning the space between the arms II, II of the stand 9, serves to clamp the bracket It to the stand in its vertically adjusted position, while allowing quick and easy adjustment of the elevation of the sinker tube 15 on loosening the clamping bolt.

The details of the sinker tube assembly are best shown in Figure 12 of the drawings, but it is to be understood that the invention is not limited to this precise construction. It suffices to explain that the sinker tube assembly includes a spring-pressed bar or rod l8 projecting therefrom towards the needle cylinder, and onto the end of which is adapted to be secured a burr bracket l9 having a collar 20 at one end to receive the end of the rod [8. A set screws 2| serves to attach the burr bracket i9 to the rod l8. At the opposite end of the burr bracket,

there is provided a stud 22 on which is rotatably,

mounted a sinker burr designated 23 and shown in broken lines in Figure 1. This sinker burr may be of conventional construction, embodying aplurality of blades, one of which is shown in outline at 24 in Figure l. The blades 24 of the sinker burr mesh with the needles 2 on the needle cylinder I, causing the sinker burr to rotate on the stud 22, responsive to rotation of the needle cylinder in the conventional manner. This meshing relation can be conveniently adjusted by adjusting the position'of the stand 9 on the slotted link 5, and/or by adjusting the slotted link 5 relative to the mounting ring 4, in the manner hereinbefore described. Other burrs, such as clearing and backing burrs and the like, may be substituted for the sinker burr 23, or may be similarly mounted on other stands arranged at suitable positions about the needle cylinder for coaction with the needles in the proper sequence.

Referring now to Figures 3 to 9, it will be seen that the outer vertical face of the stand 9 is provided with a pair of vertically spaced tongues 25, 2B projecting outwardly from the surface thereof and extending transversely across the face of the stand near its lower end. At the center of each tongue, I provide the threaded openings 21, 28 to receive the respective bolts 2'9, 30. Coacting with the respective tongues 25, 2B are slide brackets 3|, 32 which are mounted on the stand 9 for horizontal sliding move ment. The brackets 3|, 32 are identical in construction, and one of the same, 32 for example, is shown in detail in Figures 5 to '7. As will be seen from these latter figures, the bracket 32 is angular in form, providing two arms 33 and 34 arranged perpendicular to each other. The arm 33 is slotted at 35 to receive the clamping bolt 30 therethrough and permit horizontal sliding adjustment of the bracket 32, the rear face of this arm being channeled at 36 to receive the tongue 26 on the stand 9, and by coaction therewith, to guide the bracket in its horizontal sliding adjustment. The outer face of the arm 34 is provided with an elongated protuberant guiding tongue 31, and is further provided with a plurality of threaded openings 38 at spaced points in the length thereof to receive a clamping bolt 39 by which a second bracket 40 is attached to the bracket 32 for horizontal sliding adjustment in a direction normal to the sliding adjustment of the bracket 32, the bolt 39 being selectively receivable in the apertures 36.

The details of the bracket or cross-slide 40 are shown in Figures 8 and 9, from which it will be observed that the cross-slide is provided with a channel 4| to receive the tongue 31 on the arm 34 of the bracket 32, this channel 4| and tongue 31 having a sliding fit with each other to guide the cross-slide in its adjusting movement relative to the bracket 32. The cross-slide is also slotted at 42 to receive the clamping bolt 39 therethrough, thereby allowing a limited sliding adjustment of the cross-slide for each position of the bolt 39 in the selective openings 38.

The cross-slide 4D is laterally ofiset at one end as indicated at 43, and this offset is provided with a vertical socket or opening 44, preferably cylindrical in cross section, to receive the lower end 45 of another short stand 46, the upper portion of which generally corresponds to the construction of the stand 9. The lower end 45 of the short stand 46 is preferably cylindrical in form to snugly fit into the {opening 44 in the cross-slide 40, and the cross-slide is preferably provided with a set screw'4l which, on tightening the same against the end 45 ofthe stand' 46',

serves to restrain'this stand against angular movement and against vertical displacement.

from the cross-slide, By loosening the set screw 41 the short stand 46 may be angularly adjusted in a manner which may be obvious. The short stand 46 may be utilized in the same manner as the stand 9, to support other burrs such as clearing and backing burrs, pressers, or other equipment which are usually employed in association with the sinker burr 23 hereinbefore described.

Again referring to Figure 3, it will be seen that a duplicate of the cross-slide 4|], designated 48,

end of the presser stand assembly of Figure 13, is reduced in'size-as at 54 and is preferably circular in cross section to permit the same to be received in the vertical opening in the cross-slides 40 or 48. The part 54 is preferably formed as an integral part of the presser tube and is elongated to allow for convenient vertical adjustment broken lines a and bin Figure 2.

While the specific details have been herein shownand described, the inventionis-not confined thereto, aschanges'and alterations may be made without departing from the spirit thereof as defined by the appended claims.

l. Ina knitting machine having a needle cylinder and a fixed support extending about the axis of said needle cylinder at a point below the cylinder, a stand adjustably carried by the fixed support for adjustment cireumferentially and radially relative to the needle cylinder, a bracket I slidably connected to said stand for adjustment laterally relative thereto, a second bracket slidably connected to said first bracket for adjusting is attached to the slide bracket 3|, by means'of a clamping bolt 49, and another short stand 56 is mounted in the cross-slide 48 and secured thereto by a set screw 5|, in th same manner described above. In this manner, as many as three stands may be combined into one combination stand unit, and attached to the slotted mounting ring 4 by a single slotted link 5. Where the conditions do not require the use of all three stands, one or both of the short stands 46, 50, together with their adjusting slides, may be removed, and the stand 9 used alone if desired. However, when used in multiple, the stands are conveniently located in compact parallel relation to each other, and are independently adjustable both laterally respecting one another, as well as radially respecting the needle cylinder, in addition to being adjustable as a unit, both radially and circumferentially respecting the needle cylinder, all of which contributes to the ease of assembly and adjustment of the knitting machine equipment, and to the high over-all efliciency of the knitting machine.

Referring to Figures 10 and 11, I have shown a modified form of stand 9' which may be substituted in lieu of stand 9 in Figures 1 to 4, stand 9 being substantially taller than stand 9 and permitting the attachment thereto of additional equipment besides the sinker tube I5, as is sometimes preferred. In other respects, stand 9' generally corresponds to'stand 9, and is provided with guide tongues 25' and 26' for coaction with brackets 3|, 32.
