IMPROVEMENT IN SEWING-MACHINES.
specification forming part of Letters Patent No. 85,191, dated May 6, 186-).
To all whom it may concern;
Be it known that I, J; B. WINGHELL, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful improvement in Double-Thread Lock-Stitch Sewing-Machines; and I do-hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming part of this specification, in"which-- v Figure 1 is a; vertical longitudinal section of a sewing-machine with my improvements applied to it in the line at w of Fig. '3. Fig. .2 is also a vertical longitudinal section of, the machine in-the line 3 y of Fig. 3. Fig. 3 is avertical transverse section of the same in the line 2 z of Figs land 2. f
Similar letters, of reference in the several figures indicate corresponding parts.
My invention consists, first, in so organizing a double-thread sewing-machine which employs a one-pointed hook or interlocking device that it continuously sews clothor othermaterial without changing the direction of .its feed or, the character of the sewing, whether the mechanism intermediate the driving-s'haft and the shaft of the lower thread-interlocking device is set-in motion by a forward or a backward. revolution of the main shaft; second, in constructing a lower thread-case of nearly cylindric form between its ends, and of rounded form at its termini, and with a movable axial pin, and arranging the said case between twodisks, one of which has adishingconca'veface and the othera partially-cylindricconcave face, so that an ordinary spool of cotton, instead of a bohbin,may be confined from moving in the path of a circle on. its'major and minor imaginary axes, and thuspracticably be used, and, also, that the loop of the needle may be carried entirely around thecase in a manner to effect an interlock of the upper thread with the lower thread before the stitch is drawn up into the cloth with but slight fric tion or bind upon the loop of the upper'thread; third,.in so constructing and arranging the mechanism intermediate the main shaft and the shaft of the interlocking device that the needle-bar produces two up-anttdown movemen ts and the'interlockin g device two circular reciprocating movements, and thus 'fornrtwo stitchesduriugeach'revolution ofashort'cran karm of the main shaft or pulley.
To enable others skilled in the art to make and use myinvention, I will proceed to describe its construction and operation with reference to the drawings.
A is the frame of the machine; 13, the sewing-table, elevated above the bed-plate O by 'means of erect-angular hollow support of the frame, as'shown.
D is the arm, which supports on its front end the guide-box E of an ordinary spring pressure-foot, F, and of the reciprocating needle-bar G, as shown. 0n the bar and guide-box, or at other suitable points,'any of the approved tension devices may be arranged.
H is the needle arm or lever, pivoted to the upright a of the frame, and to the guide-box arm D, as at b. This lever extends forward and connects by a link, 0, with the needle-bar. It also extends downward from-its fulcrum and terminates below the bed-plate in form of an obtuse angle, or nearly a right angle. In this angular portion a slot, I, of ashape corresponding to the'outlinejustnamed,is formed.
as shown.
I is a reciprocating feeder.
J is a thread-case of cylindrical form tween its ends, except at one part, c, where it is flat, and it is tapered off at the corners, as shown in Fig. 4. The ends or heads of this caseare bulging or semi-elliptic in form, and one of them is remo \-'able,-likea cover, being fitted to a socket of the case, so as to form a smooth'continuation of it. To the center of this movable head an axial pin,f, is attached, and in the fixed head acentral bearing for the end of said pin to fit inis-formed; The'axial pin passes through the eye of a commouspool of cotton, and when the spool is in the case J it revolves on the pin. winding upon a bobbin is obviated. The thread' case is arranged iucliningly below the sewing table and directlyunder the needle, b,etween two concave disks, K K, the disk K being on its inner face ofdishing concave form, and having at its base a horizontal slide, 9, with longitudinal slot.'g' in'it, and being confined by means of a set-screw, h, to a raised seat of the bed-plate, and capable of being adjusted as occasion may require. The disk K is on its iunerface concave, but in a partiallyfcylindric form, and 'is attached fast to'a still shaft, L, which has its hearings in the boxshapedsupport of thesewing-table' 0. Both Thus the necessity of the rock-shaft P.
of the needle-arm, due to a further impingementupon and depression of' the slotted portion ot'connecting-rod R by the crank-pin W of the drivingshaft Q, and by the consequent thrust of the angled end of the needle-arm against the toothed segment-arm. The same motions of the needle and hook and a feed of the cloth take place as the pin it ascends in the obtuse-angle slot of the needle-arm, and therefore two stitches are formed during every revolution of the main shaft or vibration of The slack of the threads and the tightening of the stitches are controlled by the ordinary methods and the motions of the needle.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. Asewing-machineorganization which will interlock two threads and sew continuously in the same direction, without changing the direction of feed or the character of sewing,with
a single-pointed hook or interlocking device, substantially as described, whether the connecting mechanism intermediate between the upper needle and the hook or interlocking de- Vice is set in motion by either a back or forward revolution of the main shaft, substantially asset forth.
2. The combination of the specified lower spool'case and the specified disks between which it is arranged, and all the remaining specified operative parts of mechanism, substantially as and. for the purposes set forth.
3. The combination of the angular slotted extension ot'the needle-arm, slottedconnectin grod R, main shaft Q, rod '1, segment-arm Or, and pinion N, or their equivalents, substantially as and for the purposes set forth.
