To all whom t may concern Be it-known that I, ARTEMAS B. EDMANDs,

a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, and formerly resid' Knot-Tying Devices, of which the following f is a specification.

My present invention relates to improvements in knot-tying devices, and the purprovide a mechanism, by which the loose ends of the thread may be cut oli neatly, and of approximately the same length, and a weavers knot quickly and accurately tied.

I accomplish these results by the mechanism shown in the accompanying drawings, in which Figure 1 is a view of my device looked at from above;

he various parts of the mechanism are 'screw a5.

-the tying of the knot; and two thread cutters for cutting off the ends of the thread.

In the several figures a represents the body or framework of a hollow box or casing, 4approximately rectangular in horizontal section and having a lateral projection as seen at the top of the drawings in Figs. 1 and 2. ,n

a is a flange, or projection from one' side of the o ase a, serving as a seat for the member as to which is affixed a handle a seen `best in Fig. 5, provided with slots L7-a7 for' the reception of a strap and buckle (z8- a9 adapted to'secure the device upon the hand of the operator. The member ais adjustable upon a by means of a slot a4, andthe The bend a2 seen in Fig. 1 limits the movement of as.

Upon the interior offthe'case a, and at the interior angle formed by the lateral prov jection above mentioned, is the angular member h, Fig. 2, having the support h which carries the stud'b2 supportingythe shaft b andalso forms the support h2 of the stud i supporting the shaft e3, these two shafts b and es being at right angles to each other. The shaft b is supported byV -the stud or screw c at the outer end and by thel similar stud b2. at the inner end,- and. the shaft es is supported by the 'stud i; the shaft b is revolubly mounted von the stud b2 and the pine, and this shaft b has fixed upon it the lmember d-.d and the member m', which vshaft and members are herein shown as all integral with and operated by the trigger m, best seen in Fig. 3. The member al-d consists substantially of a longitudinal piece of metal terminating at lone end in a receptacle nl*v -for the hook needle f-f, and at the opposite extremity 1n the piece d which is upon oneface made .a segment' of a beveled' gear. vThe shaft e is beveled gear e in mesh with the beveled gear d; and forming also a part of the shaft e3 and preferably integral therewith is the arm e, having at its extremity the projectionl e2 serving as a receptacle or holder for the other hook needle g, the arm e and the arm ci being substantially counter-parts of each other and operating simultaneously in.l

planes at right angles to each other by means of the beveled gears d-e. The two shafts e3 and b with their connected beveled gears f and hook need e carriers are operated by the trigger m of ig.l 3, which is integral with theshaft b as above stated.

The gear al` is about two-fifths larger pitch diameter thanl the gear e so that the hook needle g will have 'a somewhat' longer travel than the-needle f.

m is a segmental beveled. gear which meshes with asimilar segmental gear n fixed upon the revoluble stud In, a' vertical view of which is seenin dotted lines in Fig. 4. It will thus be seen that when the trigger'I m ispulled, the beveled gears e-d' are brought into operation, each carrying its res eetive hook needle and at the same time t e beveled gears 'mf-fn,vl act to rotate the stud 'n as above stated. -The trigger m and its connected parts are restored to their normal position by the coiled spring `S of Fig. 3, this spring bein fixed to the shaft b by thetongue Ss andllxaving its other end S4 anchored to the frame, as seen in Fig. 4.

m, seen best in Figs. 1 and 9, is a stationary shear blade fixed upon the frame of the device and y is a movable blade, the two serv ing for cutting olf the thread` 1- before the knot has been tied, las hereinafter set forth. The'blade .y is fixed upon and operated by the stud n which is itself operated by the beveled gears )mfr-fn', above described.

ft will be noted that the stud n which'carries the blade g/ of the upper pair of shears against the upper ace ofthe gear n', Figs. 34 and 4, thus holding the blade y firmly against its opposing blade w. g

rwa seen in Fig. 5 is a projection from the top of the device, and carries the stud nf for the other threadand itsneedle.` It will benoted 1n Figs. 3 and 4, that the stud n is perforated wlth the hole f. This permits land 7" the movable blade thereof.

the hook needle f to pass entirely through y it when the trigger m is pulled back to its limit, and as the perforation f2 is made considerably larger than the hook needle f',

there is no interference with the operation of the blade y, as the throwvor travel of y is itself very limited.`

The end of the other thread 2 before the knot is tied is cut by the shears j-p shown best in Fig. 4, p, being the stationary b lele 1s movable blade j is fixed upon the member j and slides within the plate k which is itself fastened to the frame of the knot tier, and thisbladel j is seen best in Fig. 8, which figure also`discloses its method of operation. Fixed upon the beveled gear e which forms part of the'needle carrier e,`and a little off thecenter on which said beveled gear revolves, is a pin or stud e, seen also in Figs. 1 and 2, which pin engages the slot e5 in the member j' and a partial revolution of the beveled'gear e causes the member y' with the blade j' to travel forward sufficiently to 4shear'of the vprojecting end of the thread by means of theV blade p and j. The position of the thread just before shearing is shown in Fig. 9 and just after pulling the trigger is shown in Fig. 10.

The plate c which retains in 4place the .member j with its connected blade j" is split longitudinally, as shown in Fig. 4, `and the r amber k above the split is bent inward so as 'to force yit by a spring engagement closelyy against the cut.

lw-fw are posts rounded on their outer faces, and having aspace w. between them for the passage of the hook needle f and the reception of one of the threads, and together blade p so as to insure a clean serve 'as a thread holder, as seen best in Figs.

9, l() and l1.

The member s, Figs. 6 and 7, serves as a thread guide operating to insure the proper placing of the thread for its engagement by the hook needle. The member s is mounted so as to rock upon the stud t, and-has a .spring u to bring it back into the position from which it has. been moved .by the'ten- 1s held firmly down by means ofv the spring `0 seen best in Fi 3, which spring bearssion ofthe thread in the proper placing of the same before tying the knot. The backward motion of s islimited by the stud s'.

.r2-m3, Figs. 1, 3 and 4, is an eyelet fastened b y the flat shank :v24 tothe side of the projectlon w8 and serves to hold the thread 1 `1n proper relation to the shearsf'-y. This facilitate the admission of one of the threads, as explained later. This plate g is secured to p at its lower end so that it has a spring contact at the u per end with the stationary blade p, thus orming a clamp serving to hold the thread 2 at proper tension as seen in Figs. `9 and l0. a

' Attention is called to the fact that the under orconcave surface of the needle f is cut away, as shown in Fig. 3 and also in Fig. 11% excepting at the upper endV f of the needle. This cut away space and full sized end f serves a very important function in holding the thread 1 when ,the loo-p is formed and before it is drawn tight and away from the knot tying device,A as will be shown hereafter.

The operation of my 'invention is as fol.

lows, and can be seen best by an inspection of Figs. 9, 10, 11 and 12. The device is held in the left hand, the hand' going through the strap i5-a, the index or middle linger being in engagement with the trigger m and the thumb restingL upon the upper portion of the knot tier and holding the thread l. AOne end of the thread 1 is then passed through' the space/w and thence through the guide loop .r3 above the shears wy. vThe other thread 2 is drawn by the right hand between the clamp g and the stationary yblade p and lthence around the posts "w--w over' the spring guide s, thence through .the space 'wf and over the thread f1, the outer portion of the thread 2 being held in the right hand; the thread 2 is then drawn somewhat tightly by the right hand,l forcing forward the spring guide s until the threadI 2 slips off and a .assumes its original position, as shown in Fig. 9 leaving the thread lying' close to and around the base of the posts w-w. When this position is reached, the trigger m is pulled by the middle finger of the left hand, the two hook needlesA f-g are-thus brought forward,l g crossing over the outer or loose end of the thread 2, Fig. 10, and under the thread 1, and also under that portion of 2 lying between the posts fio-w and the clam q. The pulling of the trigger" m cuts off t 'e thread 1 bythe shears m-g/ also the thread 2 by the shear j,-12.

The relative position of the threads just l before the triggeris released is shown in Figs` 10 .and 11%. The needle f-f. as' it comes forward forces by reason of the'shape of the headi'f the thread 1 to one side, as shown in Fig. 10 and as the needle point f' advances it passes over the thread 1 as indicated by the dotted lines in Fig. 10. As soon as the threads have been cut off by the shears as above stated, the trigger is relea sed and the needlesg-g and f-f return to their original position by 'means ofthe spring s.

As it is important that the main portion of the thread 1 should not. be disturbed by the return of the needle f-f luntil the outer end of I1 is 4caught by the hook f', I have provided afclearance for the main portion of the threadby cutting away theunder por-l tion of the needle f-f, as shown in Figs. 3 and 11%. As the needle ,g4-g returns toward its original position it catches on its return path, first, that portion of the thread. 2 which lies directly between the clamp g and the posts 'l0-w, and draws it backward in a loop as shown in Fig. 11. At the same time the needle f-f in its return catches with its hook the end of the thread 1 adjacent tothe shears ari-y and brings it back over the outer end of thethread 2 which is held. by the right hand of the operator, the relative positions of the thread then being as shown in Fig. 11. I

Fig. 111,L also shows that that portion of the thread 1 lying immediately below the 85 shears -y is almost perpendicular thereto, y so that'the side barb of the needle f-f readily grasps it and draws it backward into the position shown in Fig. 11. It will also be seen in Fig. lll that the head or extrein- .f ity of the needle f-f being of full size, serves to hold securely the end looped thread 1 as the needle f-f returns to its original position and is stationary, so that the thread 1 is clamped by the'head' f of the needle -f against the underlying part of the v ody of framework at the point shown in Fig. 11%, until the thread 2 is pulled from the posts w-fw inthe final tightening of the knot. y

The threads being in the relative position shown in Fig. 11', a slight pull of the right hand upon the `thread 2 slides'the loop of ythe thread 2 off from the posts Aw-w and leaves the ends in the relative positions shown in Fig. 12, the knot being then completed by pulling thethread 2 tighter by means of the right hand of the operator, the thread 1 being retained` by the thumb of the left. hand. s
