This shuttle-carrier J is 5 sectional elevation of the same on the line 2; 1:, provided in thelongitudinal edges with grooves Fig. 8. i, into which the horizontal guide-tracks t The needle A is secured in the lower end of pass. The shuttle-carrier J is provided with the needle-bar B, guided by an aperture in the the end arms, j, and the outer side arm or lug, 50 lower end of the head P at the end of the hol; j between which the shuttle K is placed. too

I The movement of this shuttle-carrier J is at right angles to the movement of the feeding devices.

The shuttle K is formed of two sections, K and K which, when united, form the shuttle. The section K is very flat, and only contains -an anti-friction roller, it, over which the shuttle-thread passes. The section K is deeper and is adapted to contain an ordinary spool,

J, of thread, silk, &c., which is held between an adjustable studded plate, R and a plate having stud k surrounded by-a spiral spring, It, and fitting into a socket-piece, l, pivoted iu the front end of the section, K this spring pressing the stud k into the end of the spool J Theplate k can be adjusted a greater or less distance from the end of the section K by means of a screw, l, and corresponding nut, Z according to the size of the spool J To remove the spool, the plate of the stud k is pushed back, whereby the spring is is compressed so as to permit drawing the stud 10 out of the end of the spool, upon which the socket-piece l is swung upward, and the spool is removed. The spool is placed in the section K byperformingthe above movements in the inverse order. The shuttle thread passes through suitable openings in the sides of the section K, as shown in Fig. 9.

The sections K K of the shuttle are held together by an L-shaped hook, P, at the rear end of the section K, and catching under the edge of the section K and by a hook, l, at the front end of the section K, and catching on a spring catch or latch, 1 in the front end of the section K That part G of the sewingplate Gr covering the shuttle-race is hinged so that it can be swung outward, as shown in Fig. 4. The shuttle race or groove J is so arranged in relation to the needle A that the shuttle will run so close to the needle that the shuttle can pass through the thread-loop formed by the needle.

I use the four-motion feed generally used in sewing-machines. It consists of a dog or lever, h, pivoted in a slidingframe, W, and provided at its outer end with teeth m, which pass through a slot, m, in the sewing-plate G. This frame k is provided on its under. side' with a p1 ojection, m resting against a beveled cam, m mounted on the shaft h, and the dog It is provided with a projection,m resting on an eccentric cam, m mounted on the shaft h. Springs 12 press the frame h from the needle A,'and the cam m presses it toward the needle, and the cam m raises it, all these parts operating in such a manner that the teeth m, upon which the cloth rests, will be raised and moved toward the needle, then lowered and withdrawn, and so on.

The sliding frame [L2 is provided with two shoulders, n a, which strike against the ends n of a sliding fork, a on the under side of the sewing-plate G at the return movement of the frame h Accordingly as this frame strikes against the ends of the fork n sooner or later, the stitch will be shorter or longer crank 11.

that is, the stitch is regulated by the position.

of this fork n (Shown in dotted lines in Fig. 3.) This fork n can be adjusted by means of a pivoted lever, L, which can be operated by the person operating the machine.

The thread-spool L is held by a pintle, L which is passed longitudinally through the opening of the spool,and is attached to a pivoted arm, 0, pivoted to one end ofa transverse bar or frame, 0, resting on the arm 0, and provided at the opposite end with a pivoted latch, 0 for holding the end of the pintle L after the same has passed through the spool. From the spool L the thread passes through the tension device M, consisting of a fixed disk, 19, and a loose dislgp mounted on a shaft, p, projecting from an arm, p of a standard, M, on the arm 0. The collar or neck of the loose disk 19 is pivoted to a fork, V, which is pivoted to the standard M, and has its lower end pivoted to a rack, r, extendingtransversely across the standard M-that is, in a position parallel with the shaft paud sliding in a grooved track, W. A cog-wheel, M engages with the rack r, and is mounted on a shaft, m journaled parallel with the arm Gin projections or standards on the same, as shown in Fig. 1, and extending to the end of this arm. The end of this 1 shaft M is provided with a hand-wheel, M. The adjoining surfaces of the disks pp are preferably coated with a layer of felt, rubber, 850., to increase friction. By turning the hand-w heel M the rack 0' will be moved longitudinally and the disks p 19 will bepressed together or separated-that is, the friction on the thread is increased or decreased correspondingly. From thetension deviceM the thread I passes through the loop .9 at the upper end of astandard, a, on the arm (Land from this loop to the end of the take-up consisting of a lever, n, pivoted to the standard a and actuated by a connecting-rod, n pivoted to the lever n and resting on a cam, 0, mounted on the shaft D, adjoining the From the take-up lever the thread passes through the loops or eyelets P P on the head P, and from there through the eye of the needle. The presser-foot Q is attached to a vertical rod, Q, guided. in projections Q of the head and surrounded and pressed downward by a spring, It.

To the upper end of the rod Q, an arm, R, is pivoted, provided with a pin, t, passing into the curved slot t of a hand-lever, R pivoted to the head P, and serving to raise the presser-foot.

The bridge S and screw Sare to be used for attaching quilters, corders, 850., to the head. A bevel-gear wheel, T, is mounted on the shaft D about midway between the cam O and cogwheel d, and engages with a cog-wheel, T, mounted on a shaft, T at right angles to the shaft D and projecting from the arm 0 toward the operator. This shaft T has a hand-wheel, U, on its outer end. This hand-wheel revolves, as indicated by the arrow, when themachiue is operated. The movement of the IIO machine can be reversed in case the needleis to be raised, 850., by turning the hand-wheel U in the inverse direction of its arrow. The vertical part 0 of. the arm 0 is hinged by hinges w to a base, 0 on the plate F in such a manner that the arm (J can be turned or swung from the operator. A spring-latch,V, is pivoted to the part G of the arm 0, and catches on a stud, V, on the base 0 for the purpose of holding the arm 0 in its upright or normal position. When this arm isturned over or swung outward the rod D slides upward in the sleeve D I have constructed the arm 0 so that it can be tilted for the purpose of facilitating fastening needles into the needle-bar or hemmers, quilters, or other attachments to the head P. Furthermore, a very low box will be required to cover the tilted arm, whereas a large box would be required if the arm remained erect.

Theopcration is as follows: If the shaft E is rotated by a treadle or any suitable motor, the bevel-gear wheel 0 will rotate the bevel- .gear wheel 0 and the sleeve D which in turn rotates the rods D and D The bevel'gear wheel d, on the upper end of the rod D, rotates the bevel gear wheel d on the end of the shaft D, whereby the crank 11 will be operated and the needle A will be reciprocated vertically. The rod N resting on the earn 0, vibrates the take-up lever N. The gear-wheel 0 at the upper end of the sleeve D rotates the gearwheel e, and the bevel-gear wheel 0 rotates the bevel-gear wheel f on the shaft f. The bevel-gear wheel f 2 rotates the bevel-gear wheel 9, and the bevel-gear wheel 9 rotates the bevel-gear wheel which is mounted on the shaft h, causing a rotation of the same. Thereby the dog h, provided with the teeth m, will be raised, pushed forward,lowered, and withdrawn by the action of the cams m and m on the projections m and m By means of the connecting-rod H the U-shaped pivoted lever H is vibrated and the shuttle-carrier J is moved to and fro iuits slot J, whereby the shuttle will be thrown through the loop formed by the needle. The cloth is moved toward the operator. The motion is transmitteddirectly by means of shafts and gear-wheels in all cases, and belts and pulleys are dispensed with.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
