Referring now to the details of the drawings by Humor; ls 1 reprosonts the. framing of what is known as the Union Spccial sewing machine, which. i have selected being Well adai itcd for the pn poses of my invention, but it will be understood ahat Various other makes of sewing machines may be 9111- plOyOd in connect-ion with my improvements.
The machine as shown in tho accompanying drawings comprises a needle oar 2 l'iaving a pair of nocdaas S and 4 and the usual pressor foot 5 and with these parts is combined the ordinary fee well known to need any further description. In Fig. of the acconipiniying drawings is also shown the usual loopor 7 and its coacting rotary ta-l cup and ihrow-oll 9; but as my invention docs not reside in any of these needed, except that lt-inay be well to state that in tho oporznion of sowing, the two noodles 3 and 4 conct with the looper 7, and the result is two rows of plain stitching on the upper side of the fabric, and a fancy or cross stitch on the under. sido similar to What is shown in Fig. 11. It may also be Well to state that the arm 10 which carries the feed-dogs 6 is given a rcciprocating movement, owing to its connection with a rocking frame 11 (see Figs. 2, 3 and 4) which is rocked by moans of a wrist pin 12 rotating with the main shaft 13 (see Fig. 3) Within a collar or sleeve 14: pivotally connected with an arm 15 projecting from the rocking frame dogs 6, all of which are too claims to this or any other style of machine, as I intend to cover the new features in the broadest possible terms. I
By referring to. Figs. 1 and 5, it will be seen that I have formed w at I shall term a separating knife 20 i hich is fixed to or forms part-of a rin 21 scrcwed to the bed plate 22 of the mac ine, although it will be obvious that this se arator 20 may be formed onthe bed pate itself if desired.
This separating knife 20 is in advance of the two needles3 and 4 and immediately to its right is a slot 23 (see Figs. 5 and 9). Through this slot works a vertically moving knife 24 which co-acts with the stationary knife 20, and it will be obvious that if a piece of fabric is fed under the separating knife 20 and this knife 24Icaused to IHOVG'U and down as the fabric is fed, the fabric will be severed or cut so that the two parts of the fabric will be divided, one part going on one side of the separating knife and the other part on the o posite side. It will therefore follow that i one of the severedparts is caused to move to one side of the two needles and the edge of the other part to enter between the said needles, the stitching performed by the needles covers one of the cut edges and leaves I the other free. The desired spreading action is the result of forming the separating knife 20 of "the peculiar shape shown in Fig. 5 Where it will be observed that the right hand edge is slightly to the left of the right hand 1 needle opening, while the left hand edge of e5 will described the n'icchanism for giving the 1 any fabric that may be impaled on its pins 39' the separating knife slants off so far to the left as to just cause the severed part of the fabric to be fed to the left side of the left needle. The result is very clearly shown in Figs. 1.0and 11, in the first of which'ligurcs the separating knife 20 is soon as having spread the fabric so that the left sideis clear of the sewing, and the other ligure (ll) showsone' of the cut edges as free and the other one as completely covered and hidden from sight, and protected from wear, bythe row of stitching. In some of my claims .1 have defined this so iarating knife 20 as being fixed to the throat plate, but said term throat plate is to be understood as being used in its broad sense and therefore as covering the knife if fixed to the bed platior to the plate through which the needle or needles pass.
Before describing my mcclmnism fori ceases knife 24 its reciprocating up and down mo tion. By referring to Figs. 2, P and 4, it will be seen that the knife 24 is carried in a knifebar 26 which has beveled edges and is movable up and down in a guide 27. This reciprocating movement is imparted to the bar and its knife by means of a crank arm 28 working in an o )ening 28 in the lower end of the bar 26, and secured to a rock-shaft 29 suitably journaled in the support 30 (see Fi 2). At the other end of the rock shaft 29 is connected a crank arm 31 and motion is given to this crank arm by means of an eccentric 32 rotating with the main shaft 13 and the eccentric collar 33 and connecting rod 34. It follows from this that as the main shaft is rotated in the operation of the machine, motion is transmitted by the eccentric and its collar so as to rock the shaft 29, and the rocking of this shaft gives a reciprocating up and down movement to the crank-arm 27 and thence to the knife bar 26 and knife 24, thus causing the latter to move up so as to co-act with the se arating knife and sever whatever may be etween them.
I will new again refer to Figs. 1 and 5 to describe my mechanism for guiding the fabric and increasing-the tendency to separate the fabric as hcreinbefore refercrd to. Around the aforesaid ring 21, which has been referred to as being secured to the bed-plate 22, is left or formed an annular recess 36 in which is fitted a second ring which may be termed a feeding or guiding ring 37 which is formed with ratchet teeth 38 entirely around its periphery and with pins 39 projecting from its upper surface all as very clearly shown in lfiigs'. 1 and 5. This ring may be merely embedded in the recess but 1 prefer the construction shown in Figs. 6 and 7, where it will be seen that the ring is formed with a rabbct 40 into which fits the project: ing rim 41 of the ring 21, and the ring 37 is thus held in position and yet given freedom of movement in a rotarydirection only. To cause this ring 37 with its im )aling pins 39 to revolve and thus feedany fabric impaled thereon, I employ a spring-actuated reciprocating pawl 42 which is adapted to engage the ratchetlecth 38 on the periphery of the ring 37 and this pawl is given its proper movement by being connected to and sup portcdby an arm 44 (see Figs. 2 and 3) which moves in unison with the feed-dogs 6 as it is connected with the same rocking frame 11 which imparts movement to said feed-dogs. It may be here mentioned that in' order to prevent an y reverse or backward movement of the feeding ring 37 I employ a spring dog 45 which engages the teeth 38 on said ring.
From the above construction it will be nmnifcst that us the machine is operated, the pawl 42 will give an intermittent movefurther increasing this spreading effect, I i input to the feeding or guiding ring 37, and
Similarly, the other soknife 24 or that part ol the knife axis of the plate or turnelable.
Will he automatically f: l under the presses foot 5, in a circular direction. at further observed that the space betw' through Which the knife 2 passes (sci:- 5) and the path of the pins 39 is a lit l than the space between the lel't ham opening and the path of the pins I obvious result of this s tl guided in its circul- 37, that part of the or cut by the liniv- 4 will separated until it is ju t outside ol the part sewed by the two needles, and will therefore not be touched by the stitching (see Fig. 55). red edge will also be moved in the same d. cation and. thus be brought between the two needles and thus the stitching will pass over and hide the severed edge. 1
In order to assist the feeding or guiding ring 27 in giving rotary or circular movement to the fabric being sewed, l employ e circular guide or turn. ible do which is sin-- bedded in the ring 21 and rests on the bed plate 32, a. screw 47 passing through "he circular guide and the bed plate 22 into support 48 below both. This screw or trunnion, however, is not absolutely necessary, as the circular guide will work just well without it. On. tli. upper surface this circular guide or. turn-table 46 are projecting impaling pins 49 which are quitenear the periphery so to pass near as possible to the stitching. T his plate or turn-table l6 revolves freely or loosely and depends upon the movement of the ring 37 or the feed dogs 6 for its movement. Thus it a fabric is being sewed and is fed by the lead dogs 6 in the usual Way or by the guiding rin 37, and is impaled also on this plate or tron-table 46, it will be obvious that the labric and. the plate or turn-table will both moye on the l prelier to use the s riding ring 37 and the plate or turntable so together for in this case there is a row of iinpaliug pins on each side of tho stitching mechanism which insures uniform ity cl movement and prevents anv impro ier feeding but it will be within the one of my invention to use either ol those devices witli-- out the other. i am not, however, claiming; this revolving guide or turn-tablc td broadly in this application as it lorms the sub ect lilatter of a separate application lilcd on April 190i, and. serial nun'ilier 55,502). (in the present case, however, l. prefer to marl; uiding lines on the plate or turn tablc to as shown in Fig. 5 so that in. placing a. shirt or other g'z'irm'ent on the machine, the imorutor can placeit on any one of certain lines andllavc a predetermined depth ol sowing. ample if a shallow "necking is to be sowed on the shirt, the latte-r will say about one-third of the plate ll}, while it be uided or be placed over,

Although I have indicated in the i tion ol' the structuretlic o, ration of my ma chine, itmay be well to s I that the operation. of my machine is as .l'ollows The operator takes the fabric to be cut and wed and after doubling it places it in the desired position over both the guiding ring 37 and the plete or turn table l6 and after impaliny; it on the projecting pins, feeds the fabric until the separating" kniie caused to enter a small aperture made in the lold of the fabric. The presser-foothis then dropped and the machine started in the usual way. In the process of sewing, the feed-dogs and the ring 37 given a positive intermittentfeed and thus move the fabric under the presser foot, and as the fabric is so fed the under rubric is severed, step by step, by the knife 24 which passes through it, as very clearly shown in Fig. 9. As the two parts of the under fabric continue to be fed forward, they scripseparated as hereinbe'lore described and pass forward to the stitching mechanism in the separated condition. Therefore one severed edge passes tree of the needle and the other edge passes between the needles and the sewing is tl'ierelore made to overlap the last-named edge so that it is completely covered as shown. infllig. ll.
Vi hilc some of my claims cover the combination ol the sewing mechanism, cutter and guiding mechanism, it will be n'ianilest that others are not limited to the use of all of those features, the cutting D'lCllllillSl'll may be used with other l'orms of guides or the fabric may be guided by the operator. likewise, in some ol my 'Qiwllllfi; l have in- (-lu'dcd two needles, but it is obvious that my invention may be used on a machine with a single needle. These and other clninges may be made without departii'lg l'rom the spirit ol my invention, and l intend the follosing claims to cover all such variations and modifications as naturally fall within the lines oi my invention.
