Patented Feb. 12 1935 4 u i\ i I `y j1,991,1 `o;; f `i N KNITTING MACHINE mianm` 1.: Arthur currienrenacook, H., assignoto Knttng Machine & Needle Company, Frank-j- V lin, N; 11.; a `corporation of New Hampshire l u Application February'28, 1934, SerialNo.1713,328 i e p e j 'e Claims, (ol. ,163,-5)` f i i, r This invention relates to knittingmachine being formed at any convenient point in the procneedles ofthe latch type and more especially to `e' ss.-""` After the 'various manuiacturing operathe so -called' rivetless njeedles. v tions on'the' latchhave been completed,` includ- As is wellnnderstoodby those sklled in this ing the drilling of the hole'7,-'Fig. 3, to take'the l 5 art, the latch of a knitting machine needle usulatch pivot, 'the latch and the shaft are assembled 5 ally is mounted on a pivot which is either threadin the proper relation hip withtheshank 6 of the 'ed through the walls of the needle shaft or body, i latch 'correctly positiohe'd' in the 'slot *4. These or is "`riveted "to them. In using needles of' this parts are locatedgas for'exan'ple by means 'of a character, especially those of the smaller sizes and suitable jig or fixture, in the correct relationship which are'commonly" employed in `knitting fine to twopunches-'8and` 9 which are moved toward 10 goods, such as silk hosiery, it occasionally hapa Other and pp d When their ends have ar'- pens that the pivot of the needle latch will work rived at pred h poi pu loose' sufiiiently'to allow the end of the' pivotto ipro t t a d nd r m each other i a p t project beyondthe'outer surface of the needle'. o e dent w t theirfown' axes, the leteh` When this happens "`such a projecting end will and needle` "re so positioned with reference to 15 i catch a `'loop of thread and produc'e afiaw in the them, that the hole 7 in the latch shank is co work. With a View to preventing accidents of axial withthe punches; ti consequently whenthey s character, it has "been proposed heretofore aremovedttoward each other to substantially the to avoid the use of a separate pivot and to form pesitienhlirelatohshp` lhltrated l' y Short studs projecting from the oppos'te wa of force inwardly sections of the walls or "checks" 20 the latch slot into the pivot hole in thelatch, of th lat h t oppo it d s of t t p these studs cooperating to perform the functions je these POI'tOnS of the metal intothe e Of a pivot. This expedient has proved us ful in where the two sections of metal so displaced cosome sizes andvstyles of needes A common boperate to form a pivot for the latch. i These secjection to it, however, is the fact that ii the latch t are ind at d at 10 and respeetvely. It 253 is tipped or bent laterally, liris very likely t will be observed that the end acesof the tips a i spring apart the two walls of the slot in which it a d b the punches 8 and 9 are spo d is located and to snap out of place v agonally with reference to their axes and to that The present invention aims to improve the con- Of the h01e 7 in the latehconsequently, the S struction and methods of manufacture of rivettiene 10 and 12 Of the metal punched m t e 30 less `knitting machine needles with a view to overchecks of the needle body are similarly disposed coming the difilculty above described and providor inclined. These sections th ap each ing a Construction which will be more reliable and other in the hole '7, as clearly shown in Fig. 4, will have better wearing qualities. i and they abut against each other along' a plane 5 `The nature of the invention will be'readily which is parallel to the two end faces of the punch v understood from the following description when tipsa and b. Both of the sections 10 and 12 thus m Connection With the a companying draW- extend across the median planeof the latch so e and e novel features l be p i a y that there is little likelihood of springing the pomted out m the appended e checks far enough apartto release the latch.'
40 the drewing Preferably the tips a and b of the punches 8 Fgure 1 15 Slde eevaton of kmttmg and 9 are made of circularform in cross-'secchine needle' of the general type with which this mm, but they are tapered slghty and the end invention is concerned;
2 is a secona View on substanauy the portons of these tips are a few thousandths i smallerin diameter than the internal diameter 45 Showmg the parts on much of the hole '7 in the latch shank. consequently, FgS 3 and 4 are views Similar to 2 but u the metal displaced to form the pivot sections 10 trating steps in the method of manufacture of a and 12 is moved Chiefly in line thithe hola 7 needle in accordance with this invention. and does not fl lateranyte any Substantatde' In making such a needle as that illustrated in gree. The surface-smi the pun a the i 50 Figs. and 2, the shaft or body 2 may bemade tion of the p a b w themain dy po n in any suitable or convenient manner. In a typitions of the pu c are t pe d, as indicated at cal process the manufacturing Operations on the c and d, respectively, andflthe stroke of the shaft are completed, and the hook 3 is bent into punches is made such that they produce slight its final shape, the slot 4 for receiving the latch 5 counter-sinks in the checks, as shown at c' and 55 d',-Fig. 2, thus avodng the formaton of any burr or rough edge.
The pivot produced in the manner above described completely fills the hole 7 in the latch shank but still remains integral with the shaft so that there is no possibility of the pivot working loose. In addition, any danger of the latch snapping out of place is minimized and, since both sections of the pivot are unusually long for a latch of a given thickness, a longer bearing surface on each section is provided. The necessary play required to make the latch 5 work easily will be produced in the tumbling operation to which the, needles customarily are subjected after the manufacturing Operations on them have'be'en completed.
V While I have herein shown and described' a preferred embodiment of my invention, it will be understood that the invention'fis. not limited to embodiment in the exact form showrn Having thus described my invention', what I desire to claim as-new is:.
1. A knitting machine needle provided with a latch slot, a latch havingashank located in said slot, said shank having a pivot hole therethrcugh, and a pivot for said the opposite walls of said: Slots projecting into said hole in the latch shank with said parts overlapping each other in said hole. o
2. A knitting machine needle having a latch slot therein and provided with cheeks at opposite sides of said slot, a latch havinga shank located in said slot, said shank having a pivot hole therethrough, and a pivot for said latch comprising two pivot sections integral, respectively, with said cheeks, said sections abutting against ,each `other insad hole along a plane disposed diagonally with reference to the axis of said hole. i
3.` A knitting machine needle 'having a latch slot therein and provided with checks; at opposite `two pivot sections integral,
latch comprising parts of` sides of said slot, a latch having a shank located in said slot, said shank having a pivot hole therethrough, and a pivot for said latch comprising two pivot sections projecting into said hole and integral, respectively, said sections extending across the median plane of said latch.
4. A knittingmachine needle having a latch slot therein and provided with cheeksat opposite sides of'said' slot, a latchhaving a shank located insaid slot, said shank having a pivot hole therethrough, and a pivot for said latch comprising respectively, with said cheeks, said sections abutting against each other" in said'hole and having ends diagonally disposed` with reference to the median plane of the latch.
5. A'knitting machine needle having a latch slot therein and provided With cheeks at opposite sides of said slot, a latch having a shank located in said slot, said shank having a pivothole therethrough, and a pivot for said latch comprising two pivot sections projecting into said hole and integral, respectively, withsaid checks, said sections being substantially parallel to each other and both disposed diagonally with 'reference to the axis of said pivot hole. p
6. That improvement in methods of making knitting machine needles, which consists in forcing portions ofthe opposite walls of the latch slot of a needle body inwardly into the; pivot hole of the needle latch, confining said operation to approximately the portionsof the metal of the checks in line with the latch hole in said slot, and disposing both sections of the pivot sopoduced in planes parallel to eachother. but extending diagonally with reference to the axis of said pivot hole. i r a Y ARTHUR CURRIER.
