Claims.—(1.) In a sewing-machine, the combination with a needle and its operating mechanism of a circularly moving loop-taking hook and a stationary thread-case supported by its periphery in said hook, and having a relatively short peripheral contact at one side only with said hook, so as to secure an early cast-off or discharge of a loop of needle-thread within less than a half-revolution of said hook after it has taken said loop from the needle. (2.) In a sewing-machine, the combination with a needle and its operating mechanism of a circularly moving hook, a stationary thread-case having a peripheral contact at one side only with said hook, a holder for restraining the said thread-case from movement as the hook travels about it, and a take-up whereby each loop is drawn up before the next loop is taken by the hook. (3.) In a sewing-machine, the combination with a needle and its operating mechanism of an oscillating circular hook, a segmental thread-case eccentric to and peripherally supported by said hook, and a stationary two-horned holder, extending within said hook, for maintaining the said thread-case stationary as the said hook moves about it, whereby, during the opposite movements of the said oscillating hook, the pressure at the points of contact between said holder and thread-case will be relaxed or the points of contact be opened for the easy passage of the loops of needle-thread. (4.) In a sewing-machine, the combination with a needle and its operating mechanism of a circularly moving hook, a stationary thread-case peripherally supported by said hook and located eccentric to the axis of movement of said hook, and on that side of said axis toward which the needle-thread loops are first carried by said hook. (5.) In a sewing-machine, the combination with a curved, circularly moving, and horizontally disposed loop-taker provided with an interior loop-seizing beak or hook, of a thread-case peripherally supported by said loop-taker, a holder for restraining said case from moving with said loop-taker, a vertically disposed needle arranged to descend inside of the circular path of movement of said loop-taker, and means for operating said needle and loop-taker. (6.) In a sewing-machine, the combination with a curved, circularly moving, and horizontally disposed loop-taker provided with an interior loop-seizing beak or hook, of a thread-case located eccentric to the axis of and peripherally supported by said loop-taker by a rib-and-groove connection, a holder for restraining said case from moving with said loop-taker, a vertically disposed needle arranged to descend inside of the circular path of movement of said loop-taker, and means for operating said needle and loop-taker. (7.) In a sewing-machine, the combination with a driving-shaft in the upper portion of the arm thereof, a needle-bar operatively connected with the forward end of said shaft, a vertical rock-shaft in the vertical portion of said arm and operatively connected with the said driving-shaft, a vertical rocking hub or rocker connected with said rock-shaft, a vertical rock-shaft at the forward end of the machine operatively connected with said rocker, an oscillating loop-taking hook operated by said last-named rock-shaft and co-operating with the needle carried by the needle-bar in forming stitches, and a stationary thread-case supported by said loop-taking hook, and arranged eccentric to the axis of the latter. (8.) The combination with the driving-shaft c of the needle-bar operatively connected with the forward end of said shaft, the rock-shaft j connected with the said driving-shaft, the vertical rocking hub or rocker n having the arms m and p, the pitman l connecting said rock-shaft j with the said arm m of said rocking hub, the rock-shaft s operatively connected with the said arm p of said rocking hub and provided with a loop-taking hook co-operating with the needle carried by said needle-bar in the formation of stitches, and a stationary thread-case supported by said hook and arranged eccentric to the axis of the latter. (9.) In a sewing-machine, the combination with a driving-shaft in the upper portion of the arm thereof, a needle-bar operatively connected with the forward end of said shaft, a vertical rock-shaft in the vertical portion of said arm and operatively connected with said driving-shaft, a feed-bar, and connections with said driving-shaft for imparting horizontal or feeding movements to said bar, a vertical rocker connected to said vertical rock-shaft and provided with a cam for imparting vertical movements to said feed-bar, a second vertical rock-shaft operatively connected with said rocker, an oscillating loop-taker carried by the last named rock-shaft, and a stationary thread-case supported by said loop-taker, and located mainly at one side of the axis of motion thereof. (10.) In a sewing-machine, the combination with a needle and its operating mechanism of a continuously and uniformly rotating hook, a thread-case supported by said hook and having a peripheral arc of contact therewith on one side only of the latter, means for restraining said thread-case from moving with the hook, a take-up whereby each loop is drawn up to complete the stitch before the next loop is taken by the hook, and means for operating said take-up and hook. (11.) In a sewing-machine, the combination with a rotating needle-bar shaft and a needle-bar operatively connected therewith of a rotating hook-shaft connected to the needle-bar shaft so as to rotate in unison or at the same speed therewith, a rotating hook carried by said hook-shaft, and a stationary thread-case supported by said hook, and arranged eccentric to or at one side of the axis of the latter. (12.) In a sewing-machine, the combination with a needle and its operating mechanism of a circularly moving hook, a stationary thread-case supported by said hook and having at or near its periphery an interlocking connection with said hook of less than half a circle in extent, to afford an early cast-off of the needle-loops, said thread-case being held by said connection against radial displacement from its bearing in the hook without requiring the use of an independent holder for this purpose, and means for restraining said thread-case from moving with said hook. (13.) In a sewing-machine, the combination with a needle and its operating mechanism of a circularly moving hook, a thread-case supported by and having a peripheral interlocking connection with said hook so as to be held from radial displacement, said thread-case but partly filling the space or field enclosed by said hook and being arranged eccentric to the axis of the latter, so as to secure an early cast-off or discharge of the loops of needle-thread around or over said thread-case. (14.) In a sewing-machine, the combination with a rotating shaft arranged above the work-plate and provided near its rear end with two cranks, a needle-bar operatively connected with the forward end of said shaft, a hook-shaft located below the work-plate and provided at or near its rear end with two cranks and at its forward end with a rotating hook, pitman connections between the cranks upon said shafts to cause them to rotate in unison, a stationary thread-case supported by said hook and arranged eccentric to the axis of the latter so as to secure an early discharge of the loops of needle-thread around said case, as described, and means for restraining said thread-case from moving with said hook. (15.) In a sewing-machine, the combination with a circularly moving hook, and a stationary bobbin-case supported thereby, of a bobbin holding and ejecting device comprising a yielding bobbin-ejecting lever and a bobbin-holding lever movable independently of said ejecting-lever, but having a portion to engage and operate said ejecting-lever after a certain limited movement of said holding-lever, and means for retaining said levers in their normal or stationary positions. (16.) In a sewing-machine, the combination with a circularly moving hook, and a stationary bobbin-case supported thereby, of a bobbin holding and ejecting device comprising a spring-pressed bobbin-ejecting lever, a bobbin-holding lever movable independently of said ejecting-lever but having a tailpiece or cam to engage and operate said ejecting-lever after a certain limited movement of said holding-lever, and a spring-pressed locking-lever or latch to retain said holding-lever in working-position. (17.) The combination with a hook-ring provided with a loop-taking beak and with an interior groove, of a thread-case having a peripheral segmental rib or flange fitting in said groove, and provided at one end with a loop-dividing hook, the point of which is housed in said groove, said thread-case having near its heel and adjacent to the said rib or flange a second rib or flange which rises gradually from the body of the thread-case to form between said ribs or flanges a groove to receive and house the point of the said beak of the hook-ring. (18.) The combination with the thread-case 10 provided at its upper portion with the separated flanges or walls 80 and 81, the latter having the threading-slot 83, of the tension lever-spring a part of which is received between said flanges or walls and another part of which bears against the inner face of the said wall 81, and a screw for regulating the tension of said spring. (19.) The described invention relating to lock-stitch sewing-machines in its entirety and in its various forms or modifications, as also in its details, as set forth.
