My invention relates to a machine for sewing the seams of carpets in making them up from the piece; and its object is to produce a machine which is readily managed and easily operated by hand, and which performs the work required of it in a more rapid and uniform manner than is at the present time possible by the hand process, and which is adapted to rest upon and astride of the edges of the material being sewed, and to travel thereon while it is sewing the edges together.

In my machine the frame which carries all the working parts is made of a plate bent or formed into a saddle of inverted U shape, adapted to rest astride of and travel upon the edges of the material to be united, and an intermittent feed acts against the surface of the material held stationary and in a vertical position, and moves the machine progressdle is reciprocated in a horizontal path from one side of the machine, and the loops of thread for forming the stitches are interlocked by a horizontally-oscillating and verticallyreciprocating hook operating on the opposite side of the machine.

My invention consists, first, in the combination, with a saddle-frame adapted to rest astride of and ride upon the edge of the material being sewed, of stitch-forming mechanism, whereby a machine adapted for sewing can be moved on the edge of stationary material, and while being moved can sew the material.

It consists, secondly, in the combination, with a saddle-frame adapted to rest astride of and ride upon the edge of the material being sewed, of stitch-forming and feeding.

mechanisms, whereby a machine adapted for sewing is automatically fed along on the edge of the material, and while moving sews the material. I

It consists, thirdly, in the combination, with the saddle-frame adapted to rest astride of and travel over the edges of the material to be united, of means for moving said frame automatically and intermittently forward step by step, to space the stitch, said mechanism being capable of adjustment to regulate the length of the intermittent progressive movements.

' It consists, fourthly, in the combination of stitch-formin g mechanism a, the saddle-frame, and an automatic intermittently-acting feed mechanism, acting positively 011 the two sides.

of the material being sewed, while the saddleframe presses down upon the upper edges of capable of yielding to the material against which it bears and over which it rolls.

It consists, sixthly, in a machine adapted to rest astride of and to ride upon the edge of the material being sewed, in the combination of stitch-forming mechanism, a saddle, and an adjustable gage-plate applied under the bend of the saddle, and adapted to be raised and lowered with respect to the needle, whereby the machine is rendered self-guiding by having the edges of the material always in contact with the under portion of it, and at the same time the distance of the line of sewing from the edges of the material can be regulated as desired.

It consists, seventhly, in a plate beneath the bend of the saddle-frame, which is adapted for first readily receiving the two ends of the carpet, at the upper edge, while in an uncompressed condition, and then of compressing said ends and the upper edges of the carpet just previous to the passage of the needle.

through the same; also, for holding the sewed portion under compression until the stitches appear beyond the rear of the saddle-frame.

It consists, eighthly, in a sewing-machine adapted to rest astride of and ride upon the material being sewed, in the combination of a saddle-frame, stitch-forming mechanism, feeding mechanism, and a downwardly-projecting point, which is adapted to move with the ma. chine and enter centrally between the edges of the carpet sewed, and to turn in and out of the way of the needle, just in front of the transverse path of the needle, the wool or any such portions of the right side of the carpet as may be frayed or raveled out, and thereby permit the needle to pass unobstructedly through the selvage edges of the carpet, thus insuring more perfect seams.

It consists, ninthly, in the gage-plate Z1, having the downwardly-extending point and contracted channel.

It consists, tenthly, in a sewing-machine, in the combination of a saddle-frame adapted to rest astride of and to ride upon the edges of the material being sewed, a feed mechanism to move the said saddle-frame intermittently and regularly forward over the edges of the material, and a device for regulating the distance of the line of sewing from the edges of the material, as hereinafter described.

It consists, eleventhly, in a sewing-machine, in the combination of a saddle-frame adapted torest astride of and ride upon the edges of the material being sewed, an automatic feed to move the said frame intermittently forward over the edges of the material, an eye-pointed needle reciprocated in a horizontal path and through slots or apertures in both limbs of the saddle-frame, an oscillating looper situated and operating upon that side of the saddleframe opposite to where the needle enters the apertures to engage with and interloop the needle-thread, and means for operating the I parts comprisin g the combination, all combined as hereinafter set forth.

It consists, twelfthly, in a sewing-machine adapted to rest astride of and to ride upon the edges of the material being sewed, in the combination of the saddle-frame, the needlebar, the upright driving-shaft with its crankmeans for producing an oscillation of the looper and a horizontal reciprocation of the needle,

whereby all of the means are operated by one shaft. I

It consists, fonrteenthly, in the combination means for operating said rod and crank, and

devices for producing the up and down movements of the looper, as hereinafter described.

It consists, fifteenthly, in the combination of a handle for steadyin g the machine, the hand crank wheel, and the saddle frame, whereby while the machine is operated by the crank-handle with one hand on one side of the saddle-frame it can be steadied with the other hand of the operator on the other side of the sad dle-frame.

It consists, sixteenthly,in a sewing-machine, in the combination, with the horizontally-rotating feed-rollers, of the mechanism for actuating them, consisting of the rocking bar, independent spring-pawls, the continuously-revolving shaft with its cam, and the feed-regulatin g screw and spring, whereby the feed for the stitches maybe regulated, and thus the stitches shortened or lengthened, and whereby, also,

the adjustable mechanism is set in motion by the shaft which operates the needle and looper mechanisms.

I make the frame A A of the machine of a saddle shape, or of the form of an inverted U, with two limbs extending downward from the bend, with sufficient space between them to readily receive the two thicknesses of the material to be sewed. One of the limbs is provided with a stud or bearing, B, to hold the hand crank-wheel O, and the other limb supports a bracket, A on the end of which is a guide-frame, I, for the reciprocating needle-bar I. The bracket A of the guide-frame I has also a rigid bar or handle, A which is placed at the side of the frame opposite to the driving-wheel, for the purpose of guiding or steadying the machine as the hand-wheel is revolved.

The saddleframe A, within its bend or loop formed by the junction of its two limbs, is furnished with an adjustable gage-plate, b, to regulate the distance of the line of sewing from the edges of the material. This plate is made with a channel on its under side, and

this channel serves as a guideway for the edges of the material being sewed together. The channel is contracted in width some distance from its forward end, as indicatedat b so as to laterally compress the two edges of the material being sewed just before the needle penetrates the same; and at this point I) I provide a downwardly-projecting point, W, in line with the space between the two pieces of material and in front of the path of the needle. This point is attached to the plate I). The plate I) is made adjustable vertically by means of a set-screw, b, which is placed to work through the saddle-frame at the top and against the upper face of the plate. The saddlet'ra-me thus provided with the plate b will, when placed astride of the work, rest with its plate 1) bearing immediately upon the edges of the material being sewed; and as the plate is adjustable by the screw b both toward and from the line of sewing, or the needle-aperturesthrough the limbs of the saddle-frame, the distance of the line of stitches from the edge of the material can be perfectly regulated, and the control of the sameis under the operator while the sewing progresses.

The wider part of the channel of the plate I) affords a ready entrance for the material to be sewed, while the contracted part, beginning at 1) operates to compress the outside edges of the material as they approach the needle, or just before the needle acts upon them, and the downweirdly-projecting point 11 occupies a position midway of the two pieces of material being sewed, and comes in contact with and turns in out of the way of the needle such portions of the right side of the material as may be frayed or raveled out.

WVithin the space between the limbs of the saddle-frame I place a spring presser-plate, H, with its lower end secured to one side of the saddleframe A, and the upper end free and pressing toward the opposite side or limb of the frame, so as to compress between these two parts the material to be sewed, and to properly press and hold together the two thick-- nesses near the point of penetration of the needle. This presser-plate is provided with a handle, H, by which it is drawn back in placing the machine upon or removing it from the work. This handle, as shown in Fig. 1, projects through a hole or slot in the saddleframe A, and is bent upward at the end outside the saddle-frame. One of the feed-rollers to is held in bearings fixed to the spring presser-plate H, and when the presser-plate is drawn backward this roller is also moved away from the material.

The saddleframeA thus constructed is provided with two horizontally-rotating roughened or serrated wheels or rollers, a a, one being attached to the saddle-frame A and the other to the presser-plate H, and these roll.- ers are actuated, by means which will presently be described, intermittently and uniformly at one and the same time. The feedwheels are so applied that they act upon both sides of the material through the sides of 'which it is carried.

the saddle-frame when said saddle-frame is placed astride of the edges of the material suspended vertically; and the means for actuating the rollers consist of a rock bar or shaft, L, held in bearings at the back of the bracket A and carrying on its downwardly-bent ends two pawls, L L, one for each roller. The pawls are pivoted independently of each other, and work beneath and engage with pins or ratchet-teeth on the under side of the feedrollers a a, (see Fig. 7,) and either of the pawls may be thrown out of action, and at such time will be held back by the spring 0 and pin 0, whenever it is desired to stop the feeding action of either one of the rollers, this being necessary in moving or adjusting the sides or breadths of the carpet with each other to properly match the pattern.

The motion of the rocking bar L is produced by a fixed cam or projection, f, on. the upright rotating shaft G, which bears against or is in contact with an upright arm projecting from the bar, the two being kept in contact by a spring,.f The joint action of this rocking bar, cam, and the spring f produces an intermittent oscillating movement of the pawls which act upon the feedrollers.

The feed or length of movement of the sad dle-frame upon the material after each reciprocation of the needle is controlled by means of a screw, f upon the standard A. The head of this screw is placed in line with, and so that it may be struck by, the small projec tion or arm f whose length of movement is consequently limited by the position of the screw f The extent of movement of the bar L is lessened'and the stitch shortened by turning down the screw f and by turning this screw in the reverse direction the stitch is lengthened.

I employ a straight eye-pointed needle, and move it in a horizontal path by the reciprocation of the needle-bar I. This bar slides in bearings in the guide-frame I, and it is moved by means of a top crank on the driving-shaft G and a connecting-rod, G, attached thereto and to the rear end of the needle-bar.

Upon the needle-bar I, and carried by it, are also the spindle for the thread-spool, threadtension device, and slack take-up, as shown in Fig. 2.

I also employ a horizontally-oseil]ating and a vertically-reciprocating looper, M, and it is fixed to the lower end of a vertical rod, g, by This looper is in close proximity to the needle-point, and on the opposite side of the machine to that where the needle enters its apertures in the saddle-frame, as shown.

The rod 9 has a horizontal oscillating movement, and also a short vertical reciprocating movement, in a guide-tube, g fixed to the guide-frame I.

The horizontal oscillatingmovement of the looper and its rod is produced by the horizontal plate 9 secured upon the upper portion of the vertical rod 9, and having cam grooves 0r slots, into which the studs or fixed projections on the under side of the connecting-rod G and plate I are caused to enter and work during the reciprocations of the needle-bar I.

The forward and backward movements of the rod G produced by the crank causes the studs to move in an elliptical path, and as they enter and pass through the cam-slots in the i plate 9 they produce a horizontal oscillating movement of the plate, shaft, and looper; and at proper intervals a short upward movement of the looper and shaft is produced (in order to have the looper properly take the loop of the needle-thread) bymeans of an elevated part, W, of the guide-bar h, which lifts the rod g.

The plate g is guided by a pin, h and the guide-bar h as it is elevated by the portion h of the said guide-bar; and at the return movement of the plate 9 the rod 9 is brought down again to depress the looper (and thereby readily clear said looper of the loop) below the needle-point by the action of a spiral spring, w,

between guide-tube g and the lower arm carrying the looper M. This downward move ment of the rod may be produced in a more positive manner than by a spring, to, by makin g the upper end of the rod 9 with an inclined or beveled face, and placing a beveled block or stud, l, on the connecting-rod G, and by the reciprocation of the connecting-rod this part Zwill be caused to strike against the beveled end of the rod 9 and force it downward after each upward movement is produced by the means previously described for producing such upward movement.

In the operation of my machine the carpet to be sewed is suspended by means of hooks or clamps after the manner adopted inhand sewing, and theneedle of the machine is drawn back and the presser-plate held back by its handle, and the machine placed astride the edges of the two pieces of carpet to be sewed together. The handle H is now released, and the gage-plate adjusted to regulate the distance between the edge of the carpet resting against the under side of the gage-plate and the path traveled by the needle through the sides of the said saddle-frames. The handle A is now grasped by the left hand of the operator to steady the machine, while with the right hand the operator turns the crankwheel 0.

With my invention the edges of carpets can be united in a rapid, easy, and uniform manner, with equal tension and length of stitches throughout the entire length of seam, and thus the tedious work of making up carpets by hand can be performed at far less cost and labor by machinery.

The machine, as represented,is provided with suitable gearing, E F,for transmitting the motion of thehand crank-wheel to the other mechanism.
