Specification of Letters Patent.

Patented ct. 30, 1906.

Application filed December 6, 1905- Serial No. 290,656.

To all whom it may concern:

Be it known that I, BERTHOLD WIENER, a subject ofthe German Emperor, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Knitting-Machine Needles and Holders Therefor, is a specification. I 1

My invention pertains to knitting-machine needles and means for holding the said needles in their operating position; and it contemplates the provision of needles and a holder therefor of such construction that there isno liability of .the needles becoming casually displaced while in use and yet when any one of the needles breaks or isotherwise impaired it may be expeditiously removed and replaced with a perfect needle, and tnis without disturbing or in any way impairing the efficiency of the other nee s comple mentary to the holder. I

' With the foregoing in mind the invention understood from the following will be fully description and I claims when the same are considered in connection with the accompanying drawings, forming part of this specification, in wh1ch r the construction knitting-machines,

I form in cross-section and 5 5 vare horizontal sections enlarged perspective view 0 4s bodnnents.

Figure 1 is an elevation illustrating a needle-holder constructed in accordance with my invention and its full complement of needles. Fig. 2 is a view illustrating theouter late of the needle-holder removedand also lllustrating the upper portions of the needles broken awa Fig. 3 is a vertical transverse section of t e improvement. Figs. 4 and 5 taken in the planes indicated by the lines 4 4 and 5 5, respectively, of Fig. 3. Fig. 5", is an edge elevation of the needle-holder. TFig. 6 is an edge elevation, partly in section, of a modification, hereinafter referred to in detail; and Fig. 7 is a horizontal section taken inthe lane indicated by the line 7 7 of Fi 6.

, the lower portion of one o the needles common to both em- Referring. by letter to the said drawings, and more particularly to Figs; 1 to 5" there of, A A are the several needles of m provement. These needles are prefera ly of commonly employed in with the exception that their shanks or heel portions 0/ are of angular are suitably roughened, as indicated by b, for a purpose which will be presently set forth.

of which the following ig. 8 is an B is the inner member of tlie needle-holder. C is the outer member of said holder, and D D are the screws which constitute the means I which I prefer to employ for connecting the.

shanks 'or heel portions of the needles be tweensaidmembers Band- C. The member B of the holder is formed of cast-steel or other material compatible with the purpose of the invention and is provided at an termediate point of its length with a shoul fer or abutment c, as best shown in Fi 3. It is also provided at its upper edge wit a rib d, in which are a plurality of vertical grooves e for seating the upper portions of the needles i, e., the portions immediately above the shanksafter the manner best shown-in Fig. 4, with a view of bracing the needles'and in that way lessening the liability of the needles bein broken or displaced whilein use. The ishan s or heel portions 0 of the needles are preferably bent at an obtuse angle to the remainder thereof, this in order to enable the said shanks to rest flat on the portion of the 'gmember B intermediate the rib d and the jabutment or shoulder a and abut at their rear ?or lower ends against the said shoulder orabutment. This arrangement of the needleshanks is best shown in Fig. 3, and obviously it is calculated to stren then the connection of the needles to the ho der and in that way prolong the usefulness of the needles.

As best shown in Figs. 3 to 5 of the drawings,- the outer member 0 of the needleholder is provided with ashoulderf, arranged above and opposed to the shoulder a of memmembers B and 0 together and clamping the her B, and is also provided with a projection Fig. 5", the said projection 9 corresponding receive the angular and roughened I snugly arranged against and connected to the member after the manner show'n m Fig. 3 the shanks or heel portions a, will be frictionally held between the said members B and C in such manner that casual displacement or shifting of anyof the needles relative to the holder will be precluded, and yet when the member 0 is disconnected from the member B or the connection between said members is loosened any one of the needles may be readily withdrawn and replacedwith a new needle without disturbingor in any way impairing the other needles of the gang, In this connection it will be noticed that when the connection between=the members B and O is loosened the grooves h inthe proj ection g ofrthe member hold the roughened shanks or heel portions (1 of the needles and v in that way prevent displacement orchangein position of the perfect needles incident to the removal of a broken. or imp aired l needle and -'the insertion of a newneedle.

Asbefore-stated; I refer to connect: the membersBand G oft e holder throughthe mediumof screws D} Which have threaded shanks let: into threaded? apertures i in the lower-portion of the memberB and also have heads j:disposed in countersinks -7c in the lower-portionofthemember- O. I desire it distinctly understood, however, that I: do. not confine myself to.the connection of'the members B and*@ throughthe medium, of: screws, inasmuchv as :the said members may liIB CODDGC/tBd by-any suitable meanscom patible with my invention without affecting- 2 5 thesame.

In addition to the advantages which! I have aseribed to the embodiment ofimy. inT vention described. in the foregoing it will be noticed that. the said i embodlment is simple and compact: in construction and is as well: adapted! towithstand. rou hi and constant: usage asuany. other part of "t e mechanism of a=hnitting-machine The-embodiment of-the invention shown in Figs; 6 and-.7 comprises holder: members B andGI, needles -A, whioh=are similar: to the needles off'Figs. 1 to e.,4have rough?- ened or-slightly -corrugated shanks -01! heel? portions a#threaded ins D, extending lat-- erally outward from tl ie lowerportion of-the member B. and-.* through apertures in the lower-portion of the memberC", and wing or othervsuitable nuts D3, mounted on the pins. D andarra ngedto bear against the outer; sideof the memberG", so-as tor/lamp and holdfsaid: member against. the member Bi. Irncommon with'the-member-Bof the em-r bodiment'shown inFigs. 1 to 5' the member: B. of themOdifiedconstruction-is provided with an'intermediate shoulder-or abutment; whieh islettered er, and a rib on its upper ed e, the said ri-b being letteredd and provi QdWithVGI'hIQaI grooves c; The needles-\ oi the modified construetion rest.- in the groovese/ of the memberiB a and :abutat their- IOWGiR'GBdS against the ShOUIdBI'z-C. thereof and are securedin-such ositionby. the inclinedi u per portion of themember GJ. When. t 'eparts are thus arranged, the groovedu'ib-d of the member '34 will obvi ously. serve the same purpose-as the grooved. h

rib d of the embodiment shown in Figs. 1 t6 5 thatdsx tosay, will abrace and lend strength -to theneedles andat the sametime assistnin 6 5 preventing casual displacement; or shifting in.

positionof the perfect needles when the connection between the holder members is loosened and a broken or impaired needle is be- ,ing-removedand replaced.with anew needle. In bracing and strengthening the needles the grooved rib D is assisted by the shoulder or abutment 0', against which the lower ends of the needles abut, as best shown in Fig. 6.

In addition to the elements mentioned the modified construction of-Figs. 6 and 7 comprises a-strip M of rawhide, stout leather, or other suitable material: This stri Mfisinterposed'between-the shanks aof the needles and the u per inclined 'portion oflthe holder. member andit. servesrby engaging the-8o roughened or. corrugated shanks to'securelyhold the needle against casual'movement or, displacement, and italso. serves-when'the connection-between the membersB andrG is loosened to hold the perfect'needlesagainst 8 5 shifting while the broken OIriIllPlliI'Gd needle is beingremoved'andia-new needle is being substltuted'therefor;
