App1ieation filed September 17; ean-serial 110,501,290.

To all 207mm it may concern:

Be it known that 1,.EARLM. l VITIIERELL, a citizen of the United States, residing at Duluth, in the county of St. Louis andSta-te of Minnesota, have invented certain new and useful Improvements iii-Yarn Stands for Knitting Machines, of which the following isa specification, reference being -.had therein to the accompanying drawing.

This invention relates to knitting machines and has specialreterence to an improved yarn stand for what is known as-fiat knitting machines. 'lhose il'nnillar with the art know that in the ordinary fiat knitting machine the yarn stand is a permanent fixture extending horizontally away from and in :t'ront of the operator of the machine, and

in the use of such machines when it becomes necessary to change the color or quality of yarn stand which maybe quickly adjusted to or from active position on the machine and the latter quickly re-threaded without necessitating a material delay in the opera tion of the machine.

Another object of the invention is to provide means whereby a second party, other than. the operator, niay'attend to the changing or replenishing oi the yarn stand while the machine is in operation.

Other objects and advantages of the invention will appear in the further descrip tion thereof.

Referring to the accompanying drawing wherein like reference characters indicate like parts, i

t Figure 1 represents a rear elevation of one embodiment of the invention, and

Figure 2 is an end elevation of the same.

1 represents the base of a Hat knitting machine, and 2 a suggestion of the ordinary needle bed.

The yarn stand is supported upon two upstanding brackets 3 which are securely bolted to therearmost edge of the base 1, as at 4-, and, in Figure 2, I have illustrated at 5, in dotted lines, the position of the ordinary p a I; E5, v I.

-yarn stand whichmay 'or not be dispensed with inmaking use of my improved stand, as the improved stand operates above same and wholly "independently thereof,

though, of 'course, the bobbins or spool spindles in the ordinary stand 'would have t-01b6, removed if myimprovedstand were appliedutosuc h machine. I

, In the ordinary machine ofthis type there are two uprightrods 6 and? .which form extensions of the brackets .33, andPconnecting the two endsof these upright rods, extending longitudinallyof the machine, is a bar 8, this ordinarily being for the support of the take up brackets 9, the location. of which, however, are entirely changed wheremy improved yarn stand isinstalled.

In the installation of the multiple yarn stand, I provide two rectangularly shaped metal fabricated structures, indicated at 10 and 11, they beingpreierably of light angle iron and made oi sufiiciently' staunch structure in any desired manner. are pivotally hung one upon each one of the upright rods 6 and 7, they being provided for such pivotal suspension with angle clips 12 securely fixed to one corner thereof and having holes therethrough which surround the upright rods, and a collar 13 is securely fixed to each rod 6' and 7 just" beneath the lowermost supporting angle clip 12 so that in this manner each stand may be swung backwardly away from the cross bar 8 or towards and against same as the exigency of the case demands. A small metal clip 14; is attached adjacent the upper innermost cornor of the tree end of each stand and which clip is provided with a concaved notch in These frames 7 the lower edge thereof for the purpose of overlapping or hooking over the upper edge of the cross bar 8-when the rack isswung into active position on the machine and is also for the purpose of holding said rack in such position. x

Upon each rack is mounted the usual number of spaced cone or bobbin spindles 15, upon which any desired number of spools of yarn maybe applied and threadedin the usual way except that I prefer to make the spindles 15 in the two uppermost series hollowso that the threads from the lower spindles may pass therethrough and be joined with their companion threads in the upper part of the stand as desired and that the take up brackets 9 are carried upon the uppermost inner edge of each stand so that each stand is provided with its own set of take up brackets.

As an additional novel feature in connection withthis form of multiple yarn stand I propose to'use a job or work card indicated at 16 which is hung upon one corner of each yarn stand so that the job foreman, having a knowledge of the subsequent requirements of the machine, may place a card thereupon when not. in use for the information and v guidance 'ofthe party furnishing yarn to the stand so that hemay proceed tofill the un- .occupied stand ready for instant change by the, operator whenthe time arrives for him ,to makessuch. change in the work being accomplished] so that-,allhe has to do is to swing out of operativeposition the stand.

which he has been using and swing the other stand v into place and vtie inhis threads.

[From the foregoing it is evident that I have devised novel means whereby to matecarried by each stand, and bobbin spindles carried by each stand whereby one of the standsmay be replenished or, supplied with yarn while the other is in operative engagement with the machine.

. In testimony whereof I hereunto atiix my signature in the E KL M. VVITHERELL.
