Application filed March 9,1906. Serial No. 305,033-

' Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in lllindstitching Sewing Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. I

The present invention relates to that class of sewing machines which is employed in felling or making blind stitches upon one side of a fabric, for attaching'a lining, binding, or facing thereto; and in which a curved needle operates wholly upon one side of the fabric.

In the present machine, the cloth or Work-piece to be sewed is laid directly upon the iced-arm, and a foot provided with an aperture rests upon theliabric and a needle is oscillated across the aperture in iilinement with the seam, engaging the portion of the fabric which is exposed in the aperture. A raceway in the form of an open trough is supported 'abovethe toot transj needle just as it is being retracted from the fabric.

verse to the path or" the needle and also transverse to the line of the seam, with a gap or notch in the middle to iacilitate the passage of the needle, and a reciprocating shuttle is laid in this open raceway and reciprocated by the shuttlecarrier to take a loop from the A shuttle pointed at both ends is preferable, as it is adapted to engage a loop upon the needle when crossing the path of the latter in either direction, and such a shuttle needs to be oscillated only half as frequently as the needle. The arrangement of an open-trough raceway above the foot renders-the shuttle very accessible, and permits it to be placed in and removed from the raceway with the utmost facility.

The machine is provided with a frame, a goose-neck, and a head upon the outer end of the goose-neck, carrying the stitch-forming mechanism; a driving shaft being extended into the head as usual, to operate such mechanism. The foot is preferably held stationary upon the head, and the feed-arm hinged upon the frame tomove to and from the foot, and pressed elastically thereto to clamp the fabric or cloth during the sewing operation.

The raceway for the shuttle is preferably secured upon the head in a fixed relation to the path of the needle, and the foot is adjustable upon the head so as to vary the exposure of the fabric to the point of the needle. As the needle ti'avels in a curve, it intersects one corner of the :raceway,-and the point of the shuttle is therefore formed to lie in such corner of the raceway, and notin the middle of the raceway, as is arm, and is preferably made with acentral smooth space between marginal rows of teeth, so that it may press the fabric close to the needle without danger of the needles engaging the teeth. The smooth central space is preferably made level with the tops of the teeth, so as to hold the fabric up as close as possible to the path of the needle.

The feed-Wheel is preferably formed with a short journal upon each end and connected by a universal joint with a teed-arbor in the post of theirame, such construction permitting a spring to be inserted under each of the journals to press them elastically toward the fabric, and thus permitting either end of the wheel to yield independently of the other, as is often required in stitching close to the edge of a garment, in which case the pressure and the feeding are thrown chiefly upon one end of the wheel.

The curved needle is carried by a vibrating arm, and the holder for the needle upon the arm provided with a thread-guide which delivers the thread directly into a groove upon the under side of the needle; a vertical eye near the point of the needle permitting the thread topass upward so that the loop is formed directly on top of the needle, where the transversely moving shuttle .can readily engage it.

Atake-up lever is provided, and operated by a cam wvliich permits the thread to follow the extreme for Figure l is a side elevation of the machine; Fig. 2 is a. plan of the same; Fig. 3 is a section on line 33 in Fig. 1; Fig. 4 is a front elevation; Fig. 5 is a plan in section just above the level of the foot M; Fig. 6 is a plan of the foot and raceway with needle across theraceway; Fig. 7 is an end view of the feed-arm and needle-arm with the foot, the raceway, and a piece of fabric in section; 8 is a front View of the head with the casing cut away to show the interior, and Fig. 9 is a section of the head, looking toward therear side of the head, and showing the connection for driving the shuttle-arm and Fig. 10 is a plan of the head in section, where hatchedj at'the center of the. driving-shaft. Fig, 11 is aver'tical section of the head adjacent to the outer end of the head, with the connections for the needle-arm only;

ing a loop of the needle-thread; Fig. 1G is asimilar dia gram with the right-hand end of the shuttle engaging a loop;

The machine is shown with a frame having a hollow post A, goose-neck B, and head 0, with a driving-shaft D extended into the head. A shuttle-shaft E is arranged directly below the drivingshaft and connected thereto by. gears F, and a rock-shaft G for the needle arm a is shown mounted to turn, and also to reciprocate, in a bearing directly below the shuttle-shaft.

Arrangement of fecd-ar'm..-A feed-arm H has forked feet fitted within the post A and jointed upon pivots I, and it is extended beneath the head to carry a feedwheel beneath the needlearm a. A leaf spring J is secured to a seat 1 within the post and projected outwardly between the feet of the fork to the front end of the iced-arm, and an adjusting screw K is arranged beneath the spring to produce an upward elastic pressure upon the ieed-arm. The upward movement of the feed-arm under such prcssure is limited by a screw L The foot M is'mounted adj ustably upon the head by a bar M and clamp-screws N, a screw N 2 (having a bearing upon the head) being fitted to the upper end of such bar to adjust the foot vertically. A treadle 0 and chain 0 are shown diagrammatically in Fig. 1 to depress the feed arm,- when it is requisite to insert the garment or fabric to be sewed beneath the foot, i

Shuttle connetions.-The raceway P has division or gap in thepath of theneedlc, and attached to the rear edge of the head (Figs. 8 and 9), and a doublepointed shuttle Q is vibrated in the raceway by shuttle-carrier R and a shuttle-arm R, having pivot S at one side of the driving-shaft transverse to the same, and provided with spherical crank-pin S A crank upon the shuttle-shaft E is also provided with a spherical Crank-pin, and a connecting-rod T has spherical bearings fitted o the said crank-pins to oscillate the shuttle-arm as the shuttle-shaft revolves. With this arrangement the raceway lies wholl y above the foot and is curved in a vertical plane, concentric with the pivot S. The shuttle-arnrR also moves in a vertical plane as its pivot is horizontal. The shuttle-arm R moves in a vertical plane, and as its lower end traverses a curve, the raceway is corresponding] y curved in a vertical plane, but its bottom is flat transversely. The

- bottom of the shuttle is therefore flat transversely and curved longitudinally to fit the open trough of the raceway,- from which it can be readily lifted when required. With a (li'inble-pointed shuttle, the gearing revolves the shuttle-shaft at half the speed of the driving shait, thus permitting the needle to make two oscillations for each oscillation for the shuttle, and enabling the-opposite ends of the shuttle to engage the loop of the needlethrcadfi'yl'ieh crossing the path of the needle in either direction, as shown in Figs. 15 and 16.

Construction for zigzag 'sewiny.--The general construction of the machine adapts it for sewing zigzag stitches or a straight scam, the stitches requiring the moving .of the'needle laterally intermediate to its oscillations, so as to intersect the cloth or fabric in two different lines, as shown in Figs. 15 and 16. In

the present invention; such lateral movement of the needle is made inparallel planes, and is effected by mounting the needl e-ar m a upon arock-shaft G which rock-shaft, a crank b with spherical crank-pin b is attached to the needle-arm (Figs. 10 and 11), and 0s cillated by a link 0 which is connected to a spherical crank-pin d rotated by the end of the shaft D. The rock-shaft is reciprocated by a connecting-rod f having one end adjustable in a segment 9, which is vibrated by a crank e and a needle-cam 6 upon one of the gearwheels F. This connecting-rod is shown arched upwardly to afford more room for the cloth or work-piece upon the feed-arm. The segment is grooved or slotted to receivelhe connecting-pin f of the rod f, and such groove is extended past the axis of the crank 0, so that pin f may remain stationary when set at that point, as required when the needle is to oscillate always in the same path, for sewing a straight seam. The connecting-rod f is attached to the pivot-shaft G by a universal joint so as to permit the oscillation of the shaft and the movement of the rod f to different inclinations, as the pin f is adjusted in the segment. The segment g being actuated b ythe shuttle-shaft, is vibrated only half as often as the needle oscillates, and it consequently operates intermediate'to the oscillations of the needle to shift it into the two positions required for zigzag sewing. The adjustment of the pin f varies the breadth of the stitches in zigzag sewing. Fig. 7 shows a thick piece of cloth x stretched over the feed-wheel upon the outer end of the feed-arm, with a piece of thin facing or lining it upon its upper side in contact with the bottom of the foot M. Fig. 6 shows a recess with sloping side in the upper side of the foot, with aperture m through the bottom of the recess, of a width equal to the space between the sections of the raceway, and suitable for the lateral play or movement of the needle in sewing zigzag stitch es. A. beveled recess m is also shown at the end of the aperture from which the needle advances, to accommodate the needle-carrier marked a, and Fig. 7 shows the needle n engaged with a portion of the cloth 2; and thefacing u to form a stitch, and retracted partially from its extreme forward position to loosen the thread and form a loop j with which the pointof the shuttle Q is shown engaged, the same as in Figs. 15 and 16. As the needle moves through or along the aperture of the foot in orderto penetrate the cloth, it necessarily moves tangentl'ally to the feed-wheel; as it does not pass through the cloth in forming the stitches, but enters and emerges at adjacent points, as clearly shown in Fig. 7.

Thread guide and take-'itp.lhe needle is shown with I a vertical 0 e l. Fi s. 6 and 7) and rooves l/ n 7011 the under side, and the thread is led into such groove by a threadguide 7) attached to thencedle-arm or carrier close to the shank of the needle. An ear p upon the opposite end of the needle-carrier receives the thread from a gnidearm p which extends from the needlearm upwardly to receive the thread from a take-up lever V. This lever, as shown in Fig. l2, is actuated by a cam having a groove with. three different seats for the lever-pin o. The cam, as shown in Figs. 1 and 12, is

mounted upon the driving-shaft, and the take-up lever is pivoted at one side of the shalt and extended across the grooved face of the cam and downwardly toward the needle-arm to deliver the thread thereto. In Figs. 1 and 4, the machine is shown with spool AK, tension so ,the aperture m, and curve the freecorner of the same downwardly sufliciently to press upon the cloth elasticdeliver the thregd b to the take-up lever. The lever;

- its highest position gradually downward as the'needle' device B and threadguides C upon the head which Vs shown in'FE 12 in fulllines in the position, just before the needle is retracted to form a loop, and it is shown in dotted lines at opposite sides of such position, The cam revolves per arrow V and the lever-pin u is shown engaging the seat '0; of the groove, which is sufficiently eccentric to let the take-up lever move from enters the cloth. The groove then makes a sudden drop to the seat 1), which slackens the thread and per; mits the formation of the loop j upon the needle as the shuttle engages the same, and the seat 1) which connects the portions r and 1/ inclines outwardly from the axis of the cam so as to raise the take-up lef'er to its highest position, and tighten the needle-thread upon the shuttle-thread to finish the stitch after the shutthe has cleared the loop.

Attachments to thefoot.l have found that the needle itannot engage theiabric uniformly, to make uniform lstitches, with a mere foot having an aperture or throat through which the cloth can project to engage'a needle ally and prevent the same from movement, except when carried forward bythe feed-wheel. To hold the edge of a facing down upon the cloth at either side of the needle,I provide fingersr attached adjustably to the top of the 'foot, so that they may be set at varying distances apart 1 asjniay he required to admit the lateral movement of 1 "therieedle in zigzagsewing. Each finger has a straight rib which projects downwardly through the aperture m .to the top of the clpth, as shown in Fig. '14, and they ,prevent the edge of, the fabric from lifting in the aper- A o; the feed 'arm, .which is provided with two cross-bars s ture, on one side or the other, when the stitches are I made'(as along the tops of trousers bands) so close to the edge of the fabric that ,this'edge rests pon only one iside of the feed-wheel, and does not extend across the aperture.

These fingers can be ,adjusted'so as to hold .-the fabric down, no matter how close the sewing is done .to the edgeoi the fabric. w

' Feeding devices.- Figs. 7 13 and 14 show the outer end having eacha vertical slot 3 to form bearings for the journals i of the feed-wheel. The wheel has marginal rows' of teeth w and an intermediate smooth space w, whichis'preferably made flush with thetops of the i teeth, to press the cloth I upwardly, as shown in Fig. 14.-

Or'i oi the journals t is provided with a universal joint t connecting it with a feed-shait t which is extended into'the feed-arm from the post A of the machine, where it isdmrpled to a iced-arbor T having a ratchet-wheel 'T" thereonfasishhryn in Figs. 1 and 5. An eccentric 3 on the feed-shaft oscillatesthe feed-crank u' having the The feed-crank the eed-arba Tflso. that as itis oscillated by the occen 2 is showmas an arm pivoted upon piece of Cloth, as'a tric y, the pawl 14, moves back and forth over the teeth of the ratchet-wheel '1 intermittingly, and drives the feed-wheel in the required manner.

The ratchet mechanism for turning the feed-arbor is practice made variable so as to vary the iced; but the construction of the ratchet mechanism is immaterial to the .present invention.

The journals t of the feed-wheel are pressed upwardly" by the opposite ends of a leaf-spring W, and its periphery projects above the top of the feed-arm, through an opening formed in the same, such projection and the I spring-support W enabling the feed-wheel to yield dur'-" ing the operation of sewing, when material of greater or' lesser thickness is passed beneath the foot. The connection of the feed-shaft t with the feedwheel and the feed-arbor T by universal couplings,

permits the feed-wheel to yield readily when pressed downward by the cloth, and allows one end of the wheel 5 to 'be depressed independently of the other where the sewing is done close to the edge of the cloth, and the lat ter therefore presses upon only one end of the feedwheel. The ends of the wheel are rounded, as shown in Fig. 14, to permit it to tip between the partitions which form its bearings. j

The yielding support of the feed-arm permits the lat I ter also to yield, if the variations in the thickness of the 5 material excedthe projection of the feed-wheel from the arm.

From the above description it will be understood" that the raceway and, the needle are arranged in'fixed relations to one another, so that the needle may always pass beneath the corner of the shuttle. The foot is ar-f" ranged between the raceway and the feed-arm, and is preferably held stationary, as shown in the drawing,

and the feedarm made to yield for introducing the fab 'l00 ric or work-piece.

In Fig. 7, 1 have shown the top of the feed-arm curved/in cross sccti6n, and the'bottom of the foot corre' spond ingly curved at one side; but no ridge is re quired to bend the cloth for sewing in the present in-? vention, nor is, itnecessary to bend the foot in conform-g ity to such aridge. Theioot is shown bent downward at one side in Fig. '7, to clear the end of the carrier which supports and moves the needle; but the foot may be madi flat and the needle-bar or table may be made flat, as shown and claimed in the co-pending ap plication just referred to herein.

In the drawing, the reciprocation of the needle transverse to the feed-arm, and as the raceway is neccssarily transverse'tothe mode it reciprocates in a plane parallel to the lined the feed arm, with ,this arrangement; but the relation of these parts to the feed arn1 may be varied Without departing from the invention.

Where'the rock-shaft for the needle-arm has an adjustahle longitudinal movement to form zigzag stitches and to vary their breadth, it necessitates the use of uuiyersalcouplings upon theconn'ecting-rod which oscillates this shaft, and the movement of the shuttle-arm tastes the use of universal 'oints upon its connection with the shuttle shaft,- whip ,is made parallel the at right angles t'dtlie oscil\aion oi the needle necessi- The machine mayzhezopemted for fellingthe folds of seams,"for joining the edge of a to the edge of a e artrhusers waistband,- and in quilting the crinoline or stifieningin the lining i" collars, or for any other purpose to which a blind stitching machine is adapted, and can, while engaged in making zigzag stitches, be readily changed for sewing a straight seam or single lir of stitches, by merely shiftin; the pin f to the center ol' oscillation of the segment {1; the needle with whatever kind of stitching always reciprocating in the line of the seam and not transverse to the same, and taking positions in two parallel planes alternately, when making zigzag stitches. The width of a zigzag seam with this construction is governed solely by the reciprocation of the rock-shalt G and thus differs widely from those in which the needle operates transverse to the line of the seam and in which the width of the seam is produced and governed by the penetration oi the needle into the cloth,

With a transverse movement of the needle, such as has'connnonly been employed, a greater width of seam can only be secured by penetrating the cloth to a greater depth which is of course prohibited in sewing thin materials, whereas, the present construction can form a zigzag scam of any width upon material of any thickness. A wide zigzag scam can therefore be made upon thin materials, where it is desired to ornament the surface and display colored threads thereon, or a very narrow zigzag seam can be made upon thick mate rial, and unite the layers together, which is impossible vl ith thin materials if the needle operates transverse to the seam. i v

So far I am aware, my present invention is the first in which a reciprocating shuttle has been used in forming zigzag stitches, and as a reciprocating shuttle clears the needle thread in a different manner from a rotary shuttle, it enables me to operate twice as fast as if a rot ary shuttle were employed to form the stitch.

Having thus set iorth'the nature of the invention what is claimedhercin is:
