Meaiaw ]5. P. CANFIELD, OF CAMBRIDGEPORT, ASSIGNORl TO H-IMSELF AND l. F. FALES, OF WALPOLE, BMSSACHUSETTS Letters-Patent No. 86,057, dated January 19, 1869.
IMPROVEMENT IN SEWING-MACHINE FOR SEWING PARALLEL SEAMS.
Tne Schedule referred to in these Letters Patent and making part of the same To all whom-it may concern Be it known that l, F. l. GANFIELD, of Cambridge-- port, in the county of Middlesex, and State of Massachusetts, have invented new and useful lmprovements in Sewing-Machines ;-v and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled .in the art to make and use the same, reference heilig had to the accompanying drawings, forming part of this specification.
In the machine referred to,.in connection with the hereinafter-described improvements, the fabric which is to be sewed or stitched is fed through the machine with acontinuousmotion. The frame carrying the needles, as
the latter enter, pass through, and are in the fabric, will the frame is' then swung' back to it-s original position, Y
without disturbing or interfering, in either case, with the continuous forward movement or feed of the fabric.
I employ a particular inode of hanging` and operating the vibrating frame, carrying the needles, presserfeet, cloth-plate, and hook, and thereby render the movement of the swinging frame independent of the movement of such needles and presser-feet, and thus, by such improved construction and arrangement of parts, gain manyadvantages; as, for instance, the needle-bars and presser-rods, being attached to the rockershaft by means of intervening levers or arms, and independent of the motion of the vibrating frame, they involve very little weight in their upward and downward movements; also, the reciprocating frame may be disconnected from the eccentrics, while the sewingmechanism would still operate.
The presser-rods are also very conveniently attached to the mechanism operating the needle bars, and the arrangement ofA parts such as to permit of thel introduction of a Vibrating hook on the vibrating frame containing the needle-bars and presser-rods.
In the accompanying plate of drawings, my improve ments in sewing-machines are illustrated-- Figure 1 being a plan or top view of the machine;
Figure 2, a longitudinal vertical section, taken in the plane of the line x fig. 1; and
Figure 3, a view of the front end of the machine.
Similar lettes of reference indicate like parts.
The supporting frame-work of the machine may be of any suitable construction to receive and support the various working-parts of the sa1neit consisting, in the present instance, of two parallel side-frames, B B,joined or connected together byhorizontal cross-bars or braces, C C, at suitable points of the same.
D, the driving-shaft of the machine, which extends I horizontally, across from one of the side-frames B to the othei^,in each of which it 'is arranged to turn.
E and F, gear-wheels, secured to one end of shaft D, with thi: `smaller gear inside of the larger, and engagroller H, at the rear end of the machine," above which` roller H another similar feral-rollerl I, is hung.
The two feed-rollers, lil and I, are geared togetherI at their ends J.
The larger gear-'wheel F of the dliving-shait engages with a small gear-wheel, K, upon one end of a horizontal shaft, L, extending across from one sideframe, B,'to the other, in bearings, 011 which itturns.
M, two similar eccentric-wheels, secured to shaft L, around which eccentric-wheels straps N, at one end of connecting or pitman-rods 0,- iit.
These rods O, at their outer ends P, are hung to the lower end of a vertical frame, Q, suspended at its upper end, in and between the parallel side-frames B of the machine, so as to swing forward and backward thereon.
In this swinging frame Q the mechanismfor sewing is arranged or hung, which mechanism, in the present instance, is shown as duplicated in the drawings.
R, the needle-bars, carrying needles S at their lower ends, and arranged to more in vertical planes, passing through the horizontal cross-bars or plates T of the frame Q.
U, levers, hung at one end to the upper ends of needle-bars R, from which they extend horizontally, or nearly so, and are fastened to the horizontal rockershaft V, turning in suitable bearings of the upper portion of the side-frames B.
W, a vertical rod, fastened to one end of rockershaft V, outside of side-frames, from which it extends downward, and is huhg by its slotted end X upon the pin or stud Y, fixed in the gear-wheel K, hereinbefore referred to.
Z, the presser-feet of the sewing-mechanism, formed at the lower ends of the vertical presser-rods A2, moving in and through the cross-bars or plates T, hereinbefore referred to.
B2, levers, hung to upper ends of presserbars A2, and at one end to the rocker-shaft levers with their opposite ends resting upon and playing in the vertically-slotted uprights or standards O2, fixed to the upper cross-bar of the swinging frame Q.
D2, springs, coiled around presser-bars A2, to hold the presser-feet down upon the cloth or fabric being sewed, as in ordinary pressenrods of sewing-machines.
E2, the loopers of the sewing-mechanism, one to each needle, but both being connected to a common horizontal shaft, F2, placed below the bed-piece or clothplate G2 of the swinging frame.l
This shaft F2, at one end, has a crank-arm, H2.
I2, a stud or pin on outer end of crank-arm H2, on which stud plays the slotted end J 2 of a lever-arm, K2, turning upon a fulcrnm, at L2, of the stationary framework, and receivingits motion through a pin arranged to play in and around the earn-way or groove M, upon i one face or side of a wheel, Oseeured to and turn\ ing with the eccentricfwheel shaft hereinbefore referred to.
l, the bobbins for supplying the needles with thread during the sewing-operation, from which bobbins the threads pass. to the needle, through any of the ordinary arrangements of guides and tension-regulators.
Q2 Q2, two lfeed-rollers at front end of machine,rbe tween which thc'fabric to be sewed or stitched is passed, and thence, over the cloth-plate of the swinging frame, .to the other feed-rollers, at the rear or opposite end of the machine. The fabric, as it is thus passed or fed from one end of the machine to the other, with av 'continuous motion, being sewed or stitched by the sewingmeehanism, which, through the arrangement of devices hereinabove described, is not only properly operated therefor, but, by means of the swinging frame carrying the sewing-mechanism, and the manner in which it is connected withthe driving-shaft, the needles, 85e., as they are passing through, or are in the cloth or fabric, are carried along with the same, while, when out thereof, they are carried in an opposite direction to the movement of the fabric, and thus back to their original position, for theA needles to again entergthe cloth for forming the next stitch, and so on, the slotted end of the operating-lever for the looper-shaft allowing such shaft to play through the same, as the frame moves forward or backward, while at the same time the desired or requisite throw or movement of the loopers can'be produced.
Claims. What I claim as new, and desire to secure by Leters Patent, is-
frame pivoted te the side-frames of the machine, and
carrying the needles, presser-heet, cloth-plate, and hook of the levers, rocker-shaft, eccentrics, and pitman for operating the same, substantially as described.
