The presser feet thus press the goods only Ia'lso have devised for the purposeof feeding during the formation of the stitches. They conical strips of goods-such asthe conicalbod- I I 50 rise with the needles, and their pressure on ice of skirts or skirt-borders-a feed device op- 10o BEST AVAILABLE COM eratingintermittingly between the formation of the stitches, which extends substantially throughout-the width of the conical strip of goods, and which,as it departs from the shorter curved edge and approaches the longer curved edge of the goods, is adapted to have a proportionately increased range of feed-movement so that it will feed the conical strip of goods in the requisite curved path evenly and without any injurious strain or 'drag.
The feed device in which I have embodied this feature of my invention consists, as shown in the drawings, of feedrollsI-I, which are made of conical shape and of such taper or relative diameters at their respective ends as. to conform to the shape of the skirt or quilted.
The cloth to be sewed passes over the clothplate I, under and back of the lower roll, thence up between the two rolls and to the front of the upper roll, over which it'finally passes. The rolls are made conical only for the purpose border to be above mentioned. To feed straight goods they are made cylindrical. the sewing-frame.
They do not move with They have no movement of lateral reciprocation, but revolve in bearings formed in a stationary frame, H. They act intermittently, resting during the forma tion of the stitch, and ieeding the goods when the needles are out of the cloth.
The intermittent movement of rotation is produced as follows: The lower roll is the one that is positively acted on. movable boxes acted on by springs, which cause it to bear with yielding pressure on the lower roll, the two rolls being geared together, as shown.
The shaft or journal of the lower roll is at one end prolonged to extend beyond its bearing, and on this prolonged end is mounted a hub, the periphery of which is encircled by a spring rlng-like clasp, c, which is not a con tinnous ring, but hasseparatc ends, one of which, d, carries a yoke, d, The other end, 0, directly above the end this free, and normally is somewhat separated from the other. Pivoted at f in the yoke 01 is a lever, g, whose shorter arm overhangs the end a, and whose longer arm is in contact with a cam, tappet, or eccentric, h, on the driving-shaft, said part It being of 21* Wit th snfficient to allow it to reciprocate with t- 1e sewing-frame without quitting the lever.
When the longer arm of the lever is raised by the cam its shorter arm bears on the end 2 of the spring-clasp, and first forces it down toward the other end, and so causes the clasp to clutch the hub. The continued movement of the lever now causes the hub to make a movement of partial rotation, thus operating the feed-roll. The extent of the movement of the roll is determined by the amount of lost motion of the lever, and this lost motion is regulated by means of a screw, 9, in the shorter arm of the lever, which may be caused to apprcach the -end'a of the clasp more or less, as required.
The ctherroll hasis caused to engage and operate the feed by means of a vibratory lev&, which is caused to act on the clutch sooner or later in its stroke, according to the length of stitch required. The lever is held down 'to the eccentric It by a spring, h. I
The same kind of mechanism is employed to give movement to the laterally-reciprocating sewing-frame. In this case, however, as seen in the drawings, the mechanism is dnp1i-. cated, one friction-clutch, i, and lever j being required to move the frame in one direction, and one friction-clutch, 7c, and'lever I being required to move the frame in the other direction. The mechanisms are. mounted one on one side and the other on the other side of central flange, m, on a shaft, n, which is rocked back and forth by the action of the clutches, and is connected with the sewing-frame by a rod, 0, jointed at one end to an arm projecting from the sewing-frame, and at the other end to a radial arm projecting from the shaft 12. or from the flange m thereon.
The levers j and Z are held by springs p 11 against the pattern-cams, by which they respectively are acted on, and this brings me to the last portion of my improvements, which relates to a pattern mechanism, or mechanism for giving to the sewin g-frame the lateral movement required for the particular pattern to be made.
111 my patented machine I use for this purpose a peripherally cam grooved patternwheel. This wheel is required to bechanged not only for each regular feed-a. 6., for varying lengths of stitches-but also for every figure or pattern. To remedyineonveniences arising from this plan I havenow adopted a permanent wheel, J, gearing with the driving mechanism, and carrying on its opposite faces the cam-points s, which operate the levers of the friction-clutches. These cam-points are removable from the wheel, and may be replaced by others, so that with the same wheel any number of pattern-cams can be interchangeably used. The campoints s'may be in one piece with the central disk S; or they may be' made separate from the disk and attached independently of one another to' the wheel. The wheel is of a size to make one element of the design or, pattern, so that at each revolution of the wheel one element of the design will be completed. For instance, the cams shown in the drawings will make the zigzag pattern shown iii Fig. 4, and that pattern is e uposed of a number of elements, each of w consists of up-and-down lines in V for hile the series of cams on one side of the act on one lever the other lever is opp the open space on the cam-disk on the ot de of the wheel, Thus the one set of cams, ac ing on'onelever by a series of intermittentv impulses, draws the sewing-frame in one direction. Those cams then becomeiuactive, and the opposite set commences to act on the other lever, ausing the frame to move in a ICC.
similar manner in the other direction, thus, in
conjunction with the regular forward feed,
causing a pattern to be produced like that shown in Fig. 4.
I have described only so much of the machine as required to illustrate my improvements. The stitch-forming mechanisms, one for each needle, may be of any approved pattern, embracing tension, takeup, spool-holder, shuttle, or book for the under thread, &c.
Having described my improvements,wl1at I claim, and desire to secure by Letters Patcut, is-
1. In a maehine for quilting conical strips of goods, the combination, with the series or gang of sewing mechanisms and the clothplate which supports the goods under the action of the same, of a feed device operatingintermittingly in theintcrvals between the formationtof the stitches,-which extends and op; erates substantially across or from edge toedge of the conical strip of goods, and which, as it departs from the shorter curved edge and approaches the longer curved edge of said goods, is adapted to have a proportionately increased range of feed-movement, substantially as and for the purposes set forth. 1
2. The combination, with a series of vertieallv-reeiprocating needles mounted in a laterally-reeiprocating sewing-frame, of conical feed-rolls and mechanism for causing them to act intermitlingly during the intervals between the formation of stitches, substantially as herein shown and described.
3. The described mechanism for operating the feed, consisting of a friction-clutch clasping the feedshaft, in combination with a vibratory pivoted lever supported on one end of the clutch, nd having one of its arms overhanging but not attached to the other and free end of the clutch, substantially as set forth, so that the movement of said lever shall cause the clutch first to close upon the shaft .and then to rotate the same, as set forth,
whether the said mechanism be used to operate the forward or lateral feed.
4. The combination of the frietiolrclntch, the feed-shaft embraced by the same, and the vibratory lever provided at that end, which acts on the clutch, with means of adjustment, whereby the lost motion of the lever may be increased or decreased at pleasure to regulate the length of feed.
5. The combination, with the sewing-frame, of the pattern wheel and removable patterncams, one set on each face of the wheel, the one set designed to move the sewing-frame in one direction and the other set in the other direction each set acting alternately on the frame, and both being removable, to allow different setsof pattern-cams to be interchangeably used on the same wheel.
6. The pattern-wheel with removable pattern-cams, one set on each face of the wheel,
in combination with the friction-clutches and their operating-levers, one set for each set of pattern-cams, and a rock-shaft, on which said clutches aremounted, connected with andimparting a laterally-reciprocating movement to the sewing-frame, substantially as herein shown and set forth.
In testimony whereof I have hereunto set 'my hand this 13th day of January, 1880.
AUGUST-BECK.
