To all whom it may concern.'

Be it known that I, Bum' A. Pmnsoiv, citizen of the United States, residing at kford, in the county of Winnebago and 5 .State of Illinois, have invented certain new and useful Improvements in Knotters, of which the following is a specification.

The invention has reference to devices used in the textile srtsfor unitin the ends l0 of thread or yarn, and while it re ates more particularly to that class of tyin device which is mounted upon the hand o an op erative the invention in some of-its phases w in not imited to use in this manner.

provide a knot-tyin implement which is of an advantageous c aracter from a struc tural 'int of view as well as'fr'omian opera'- tive endpoint, reducing Lthe cost of manu- 20 facture to a minimum'consistent with a high deree of eiciency in operation. i fr' orespecic ob'ect of the invention is to pgvide a knetter aving asmoothly and il f operatin actuating mechanism com- 25 l y arrange and enclosed within a small cylindrical 4casing rotatabl mounted-in a -supporting frame, the who e being capable (of su rt upon the hand of the operative in an s tantageous manner permitting oft.

improved construction for the" tying The embodiment of the invention selected for purposes of illustration includes means whereby the knotterfmay be conveniently 56 mounted u on the hand'of the operative.

Brieiiy,l t e knetter comprises a casing 10 i cylindrical in form and rotatably mounted in a generally U-shaped frame 11 carried by a member 12. By means of this member, 00 together with a strap (not shown); the device is mounted u on the hand of theA operative. A tying bi 113- is rotatably supported by the casing through the medium of a spindle 14 journaled transversely thereof and having a caring connection with an element 15 within the casing, the element 15 bein fixed ith reference to the frame 11.. 4 On t e exter r of the casing adjacent the tying bill `13 is a thread clamping device l -16 which is also fixed with reference .to thefraine 11 so that in theoscillation of the. casing, the tyinlliill moves with reference to said device. e latter is operatively associated with the casin so that in the move- 7 ments of the casing e device is actuated to clamp"and hold the thread ends during the formation of the knot The means for oscillating the, easingV com rises a thumb lever 17 made rigid vwith 't e casing, and l $0 torsion s ring llone end of which is mede fast tot e casing and the other end to element 15 which is ri id with the frame 11.

The casingv 10 is cy indrical in form and ,l comprises a m'ain or cu section 1.0* having BI a cap portion 10" detac ably-'secured in po sition in any suitable way. Herein said means comprises albowed spring member 19 formed of Wire end having its opposite ends bent outward] so as to project t ough reg- W istering open ngs in the two overlappin portions of the casing. In the iphei wall of the `casing 'is provided a ating 20 in whichis journaled one end of the spindle 14, and diametrically opposite said bearing and secured within the casing is a member 21 providing a. bearin for the op osite end of the spindle. Sei member a o has a socket 22 formed therein to provide a cam barrel for actuating the tying bill in a man- 00 ner well known inthe art. Said tying bill -iis"carried by the spindle 14 and projects through an opening 23 in the peripheral wall of the casing.

The frame l1 comprises side members 11'-l and 11b spaced apart suilicient to receive between them the easing 1.0,wli'ieh is rotatably supported thereb'ygv and 1s rigidly' secured 4upon the member 12. Preferably the upright portions of the frameare shaped t0 formguiding,means for use inipositioni'ng the threads to be united in operative relation to the tyin bill. Thus the member 11'l is shaped so t at its forward edge extends be-V provide a guidingedge 24 which merges in 'a 'notch' 25 forming aliook merifiber26v for receiving the threads to beunited.` A The tying bill 13, which is carried by the spindle 14, com rises a rtion 27 fixed with reference. tot e s in le and carrying a pivot, pin 28 upon .w ich is mounted a'shear.- ing and clamping jaw 29,'and a stationary Qian-'vV or bill 'spring .369i The lower portion ofthje jaw29' is sh'irped to provide a com 30 wingl adapted tocbact wit the cam bar- 'rel"`22 for operxiiioii vthereby in the usual mim'ne'r. `A 's'shown in' Figs. to 9 inclusive, the ortioiil Zfiff tli'etyingbill' is made intengrllwiththe spindle 14.

The stationary element 15 comprises a stem 38 disposed coaxially of the'casing endv a .bracketf portion 39 ,substantially ci rcular in form and ri 'dly "securedl to the stem. 4The latter inay e provided for this purpose with a nnge 40 to which the bracket isfrigidly secured.

'Theupper ends of-tiieimembere 48- nd 49 are 'sha to provde-ffstationary jaws 56 while-t copper end of 'the memberto is'- shaped to!'plroviclel movable jaw V57. VIn 'order thatt "e casing tney opcillate' with reference to the clampin device, it is provided in its eripheral wal with a slot 58 (Fig. 6) and to hoid the clamping device stationary during the movement o the casing, the circular member 39 of the element 15 is provided with an arcuate peripheral flange ;ment by the thumb of the hand which carries the knetter. The spring 18 which serves to restore the parts to their normal position is in the form of a torsion sprin surrounding the stem 38, and having one en secured u on a pin 62 (Fi 2) rigid with the stem and) its opposite en detachably connected with a ton e or linger 63 struck nwardl from the peripheral wall of the casing at Atiie edge of the cu shaped section 10l thereof. The extent o movement of the casin by the operation of the thumb lever 17 isimited by the engagement of said lever with the lower end of the frame 11; and to limit the return movement of the casin by the spring 18, a projection 64 is provi ed on the lower peripherv of the casing. This projection is an ranged to engage with a stationary stop which is herein 1n thc ,form of a fiat ring member 65 carried by the hand ho ding member 12. This spring member, it will be seen, serves to cushion the impact of the projection. and thus relieves the knetter of undue shock and stress.

Briefly, the operation of the evice is as follows: 'Ihe two strands oft read to be united are placed, with the aid of the guiding edges 24 and 24' of the upright members of the .supportingI frame, in operative relation to the tying bill..13 and the clampin device16`. Relative movement is then e fected between the tying bill and the thread clamping device through the movement of the casing 10 by means of the thumb of the operative engaging the lever 17. In this swinging movement of the casing,l the spindle 14 is swung with reference to the bracket 15 so that. the pinion 46, meshing with` the stationary gear segment 47, rotates the spindle and hence the tying bill, the parts hein relatively roportioned so that the tying bi rotates `sagst/,antially through one and onehalf revolutions. In such rotation of thetying bill, the loops of the 'knot to be formed nre made while the threads are clamped by `the clam in device 16. This clem mg action of t e evice 16 is accompli' .bv the character.

stationary rative connection between the intermediste member 50 of the clamping device andV the cam member 53 secured to the casing, the cam groove 52 being shaped to produce the clamping action upon the initial movement of thea casing 10. In the continued rotation of the tyin vbill 13, the threads are clamped thereby an bill approaches the end'of its stroke the loops are stripped therefrom while the ends of the threads remain clamped so as to tighten the knot. lever 17 by the -operative the spring 18 restores the parts to, their initial osition.

It will be'seen that I have prodhced a knottying implement of a very advantageous then severed, and as the tying Upon the release of the.,

The construct-ion is simple and the partsare very compactly' arranged.

Moreover, the actuating mechanism is wholly enclosed and the relatively movable parts so mounted and arranged with reference to each other as to provide a smoothly operating mechanism of high efliciency.
