jllc it known that I, FRANZ Crucifix, a citizen of tire-(herman, Empire. ri-isiding at (,hemnitz, in thi, Kingdom of Saxolly, (ier many. have invented certain new and use lul impl-ovenlents in llosiery-Fralnes; and l doiherchy decl-.ire the following to'hc a' full, clear, and exact descriptonof the invention, such ns'will ,enable others skilled .in the artto which it appertnins4 to make .and use the saine, reference being had .to

the aci'zonipanying drewingsend to letters or figures et.4 reference [marked thereon, which form a part of this specification.

My invention relates to improvements in hosiery frames, and more particularly' 'in the mechanism :for reducingr and increasing' of the thread guide. reinforced portions in knitted goods on fiat hosiery frames the inward stroke of the thread guide is limited h 'y..1|'1ea.ns of fixed stops which correspond 'to the desired breadth oithe reinforced portion. -By means of such a mechanism only reinfm'ced portions'can be made which have straight border lines, while it is not possible to makeliancy reinforced portions.

The object of the improvements is to provide a mechanism by means of which fancy wreinloixzed portions can be made. With this ohjectvinjricw lniv invention cons lt -riding,mechanism for limiting' 1When in a ki n g stroke oi the thread ,froide whirl `can he4 regulated autoinaticall.)r while the niachinc 1s in operation.

,For explaining the operation of.; the. 4

l assumed that l iifhee-l portion isto be knitted which is to he 4gradn ua lv reinforced from the points A or A. to the points B or B", whereupon the reinforced `portion `is uniformly eontinued to the points-f()4 andV C' -respective1y, and is gradually reduced to the points D and D.

When starting the manufacturegof the goods the locking-pewl 31 act-ing jon the vratchet Wheel 10 is thrown int inoperativeposition, so that the. racks 1.1,and12 are shifted b the spring 18 into initial posi. tions, an -the stop 14 is in-,its extreme position-at the' right, and the stop 16 in its extreme position at the left. The shaft 28 and 'the cam 29 mounted thereon 'areconstantly rotated vin the direction of the ar.

row shown in Fig. 2. The linli 2T is'coni 12, are shifted. *As the spring 18 has th'e Apull therack 12 to the left the tendency to :31. is-provided'v by means of pavvl 33 Dis'thrown out of llookin *positionr 'trolled by a. counting mechanism 'such as a jucqiiard'pattern, narrowingchain, or the like. -When pulling the sii-'nie tothe right and inthe direction of the arrow the lever 26 shifts, the sleeve 2J into'the p ath ol the rain 29. 'lhereby tjlie push'r'od 2() is shifted ii yn'vard, so that' the; "pawl ad vaiices the v ratchet wheel 10 and the gearwl'ieel S) connectedv therewith, so that| the-racks 1'1 and locking paw which the return movement of the ratchet Wheels 10 and 1 0 is prevented. "Normally the forward movement of the ratchet wheel 10 is prevented by means 'of thepawl 33. VVhen'thefpush rod 20 is shifted upward-the by means of the rod connecte 'with the Aarm ofthe said pawl, so tthat the ratchet wheel is nowvfree to be inov'edvby the pawl 22., Upon the'freturn movement ofthe push rod 2() the pawl 33 fallsagain` into engagement with the; ratchet wlee'l. Upon each forward niove'nient of the ratchet' wheel '10 the rrack 11 isshifted -to the left andv the rack 12 to the right, so thatthe distance of vthe stops 14: and 16is reduced. Thereby the fin Fig. 4in which theright hand stop 1-Ll Strokes of the "thread guide bars are' increased'accordingly,'because the stops l6 and 7 get into engagement withlthe Astopsl'it and 16 later, andA `the thread guides 3 Aand'ltcan be approached to each other more and more. Thereby the reinforced .portion A-B or A/V-'B can be'i'nade the border lines ofVVT which are directed aiigularly ii'1\vard,"see

Fig. 1. As the ratchet wheel 10is further advanced in the :manner just described, thc racks 11 and 12 are shift-ed froni=tl1e position shownin Fig,v 3 into the position shown ofthe `raclgll isfin the position correspondingy .to the rightliand stop 17 ofthe rac'k'12,

andl the ,left hand stop 16: of thera'cks11 is iii aposit-ion corrcspondingto, the left hand vstop loof the raclr 12'- 'The stops and 7 of the thread guide-bars 1 and 2 have such breadtlis, that they are in the'paths of :both4 the stops 14, and 1'( and 15 and -16 respectively.

Ithe' ratchet Wheel 1()- is further advanced,

at `the right` the stopfl? of Athe rack 12 is brought into.k cooperation :with the stop 6 of the threafl guide bar '1,-ai`id1'at -the left thestop 15 of the rack 11- isbrought i-ntocoi operation with the stop 7 oftliethreadguide vbar 2 (Fig, 4.) Thereafter the stops 15 and `17 are'- mo'ved farther outward, so that the with a pair of of the thread guides, a

movement of the thread. guides 1 and 2 is shortened atthe inner end, and the rein- :forcedportion C-Dor v(y-D is produced the border line of which is directed angiilarly` outward (Fig. l); It willv readily be understood, that the position of the points B and B', that is the 1nner limi-t of the reinforced portion depends on the distance ofthe stops 14 and`15, and 16 and 17 respectively. By setting the stops in different positionslthe relative position of the lpoints-B` and B can be changed. In

any case it is necessary iist to obtain the breadth of the reinforced portion which` can be attained with-the racks 11 and 12, before the'breadth` or' the reinforced portion can be reduced again.

' In the example lshown in Fig. 1- the breadth of the reinforced portion remains the same on Athe. parts bordered by the li'nes B-C and lB- C, for which purpose the ratchet wheel 10 is not shifted when knitting these portions. Of course, such parts with parallel border lines can also lbe made at any `)arts of the linesl A-B and (l-D, or A- if and CX-DQ for which purpose the counting mechanism by meansjof which the roller 24 is brought into the 'path of the'cam 29 'is thrown 'out of action. But also `in these cases the portions with inclined and lied tothe innermost points B, B,. before the return movement is possible.

I'claim herein as my invention:
