T0 to whom, it may concern:
Beit known that I, JOHN HEBERLING, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New" This invention relates to a rotary take-up for sewing-machines, which is of such construction as to tighten the stitch quickly with the least possible strain upon the needlethread, so as to leave plenty of time in the rotation of the driving-shaft for the operation of the other parts of the sewing mechanism and so that the danger of breaking the needle-thread when the machine is running at high speeds will be reduced to a minimum, the improved take-up being of such construction and being so timed relative to, the movements of the needle and shuttle as properly to control the needle-thread at all times, so
that during no part of the stitch-forming operations will there be an objectionable amount of slack needle-thread.
To this end the improved take-u p com prises tion to each rotation of said shaft and pref-.
erably at a uniform speed, said rotatingwheel or device comprising three or more connected disks, preferably of skeleton form and separated from each other in such a manner as to provide two or more distinct thread-passages, and the said rotating wheel or device also comprising two or more eccentric oppositelyacting take-up pins or studs, so that in tightening the stitches two or more bights of needle-thread will be simultaneously formed, thereby taking up slack quickly with less strain upon the thread than would result in taking up an equal amount-of slack thread in an equal time by forming a single slack-tightening bight of thread. The said rotary takeup also preferably comprises two or more eccentric slack-controlling pins or studs so disposed as to let off the slack needle-thread slowly as it is required by the shuttle, and said rotary take-u p also preferably comprises an eccentric pull-off. pin or'stud to draw a suitable amount of thread from the threadsupply at each stitch.
In the accompanying drawings, Figure 1 is a front side sectional view of the head or forward part of the arm of a sewing-machine embodying the invention. Fig. 2 is a front end view of the machine with the parts in the position which they occupy at the moment when a loop of needle-thread has been carried by the shuttle to cast-off position and the take-up or stitch-tighteningoperationis about to commence. Figs. 3, 4, and 5 are front end views of the head of the machine and showing the parts in difierent positions from each other and from those represented in Fig. 2 to illustrate the take-up or stitch-tightening and thread slackening operations. Fig. 6 is a plan view of the head or forward part of the arm of the machine shown in the other views. Fig. 7 is a detail perspective view to show the connection of the lower thread-guide with the presser-bar. Figs. 8 and 9 are enlarged detail views illustrative of the adjustable controlling-pin.
Referring to the drawings, A denotes the forward part of the arm of a well-known type of sewing-machine, and B the rotary drivingshaft, journaled in the upper part of said arm and provided at its forward end with a crankarm or disk b, provided with a crank-pin I), connected by a pitman Z2 with the needlebar G to reciprocate the said bar. in the usual manner. Connected with the crankcarried by said disk I), is a disk cl, prefer ably cut out or made in skeleton form for lightness, but having a central hub or part by which itis clamped or otherwise suitably attached to the said disk 17 said skeleton disk d having radial arms and an encircling rim. Attached to the disk (Z at suitable points is a second skeleton disk d, and attached to thesaid disk dis athird skeleton disk (1 these several disks also having radial arms and encircling rims,said disks being attached together at suitable points in such a manner as to be separated from each other, thereby forming two distinct thread-passages, and the innermost disk d being separated from the face-plate A in such a manner as to leave a thread-passage between the said innermost disk and the outersurface of said face-plate. Attached to the innermost disk (I and disposed in a recess in the face-plate Ais a ring (P, which is separated from the said innermost disk, so as to leave a thread-passage between said disk and said ring. Between the disks (Z and d is a take-up pin or stud d, and between the disks (1' and (Z is a second take-up pin or stud (1, preferably arranged diametrically opposite to the said take-up pin or stud d so as to act in opposition thereto. Also between the said disks (Z and (Z are two thread controlling pins or studs (1 and (1 and between the said disks d and d is a third thread-controlling pin or stud (1 preferably made radially adjustable on an arm of the skeleton disk (Z by means of a slot (i in said arm and a set-screw d, by which a small plate (Z carrying said pin or stud d maybe secured in diderent positions of adjustment. The thread-controlling pin or stud (1 may likewise be adjustably mounted on the rotary take up wheel or device, if desired. Between the innermost take-up disk dand the ring d are one or more eccentric pull-off studs or pins d two being employed in the present construction.
Attached to the face-plate A and overhanging the rotary take-up wheel is a thread-guide a, having two thread-eyes a and a registering, respectively, with the thread'passages between the separated skeleton disks d and (Z and d and (Z and having a bridge portion a between said thread-eyes overhanging the central disk d, said bridge portionserving to prevent the thread from coming in contact with the disks when it is taut, so that it is handled with the least possible friction and wear. Beneath the rotary take-up wheel and preferably diametrically opposite the thread-guide a is a second thread-guide 6, preferably having a single thread slot or aperture, said threadguide 6 being preferably connected with the presser-bar E, so as to rise and fall with the varying thicknesses of fabric passing beneath the presser-foot e. The thread-guide e is also preferably so arranged as to keep the thread when taut from contact with the sides of the disks. By connecting the thread-guide c with the presser-bar an automatic regulation of the amount of slack thread drawn up by the take-up is provided for. Thus when thicker work is passing beneath the presser-foot and the thread-guide c is lifted nearer to the takeup wheel more thread will be tightened and slackened, as required by the thicker work, and less thread will be handled when the work is thinner and the presser-foot falls.
The needle-thread runs from the spool or other source of thread-supply through a plate, thence between said face-plate and the innermost disk 01 and in front of the ring (l recessed in said face-plate, and thence to guide-pin on said face-plate, through the tension device F, thence through the guide eye or slot formed in the thread-guide e, and thence upward between the disks (1 and d to the thread-eye a at the top of the rotary takeup device or wheel, thence over the bridge portion a of the thread-guide a to and downward through the thread-eye a and between the disks (1 and to the thread-guide e, and thence to the needle 92.
The operation of the improved take-up is as follows: \Vhen the shuttle s has carried a loop of needle-thread around the bobbin-case s to the cast-off position shown in Fig. 2, the needle-thread has been fully slackened for the purpose of permitting of-the formation of a loop of needle-thread of the size required by the shuttle. At this time the take-up pins or studs d and are adjacent to the threadguides a and 6; but as the take-up rotates in the direction denoted by the arrow in Fig. 2
and the said take-up studs pass away from saidthread-guides bights of thread are formed by said take-up pins or studs and said thread eyes or guides by deflecting the two limbs or sections of thread extending between said threadguides away from the latter, so that when the parts have arrived in the positions denoted by Fig. 3 theslack is partlytaken up,and when the rotarytake-up has arrived at the position denoted in Fig. 4 the extreme take-up movement has been effected and the stitch is fully tightened. The entire take-up or stitch-tightening movement is thus accomplished in a quarterrotation of the driving-shaft or slightly less. As the parts move forward from the position shown in Fig. 4 to the position shown in Fig. 55, causing the take-up pins or studs to again approach the said thread-guides CL and e, the thread is slackened, the needle at this time descending for the formation of the next succeeding stitch, and the thread-controlling pins or studs (1, d and (Z at this time serve to control the slack thread, so that it will not be given up too rapidly. By the time the shuttle has taken the next loop of thread from the needle the adjustable take-up pin or stud (1 will have arrived in a position directly beneath the thread-guide a and will thus have yielded up the entire slack thread controlled thereby, the slack controlled by the pin (1 having been previously yielded up,and before the shuttle will have quite arrived at its next cast-off position, as shown in Fig. 2,the threadcontrolling pin or stud (1 will have arrived in line with the thread-guide e and will have thus yielded up the entire slack needle-thread which it controls. During this thread-slackening operation and while the needle-bar is rising and the shuttle is entering the loop of needle-thread the pull-off studs or pins (1" will have acted upon the needle-thread running between the thread-guide a and the tension device in such a manner as to have IIO drawn a sufiicient supply of needle-thread through the tension device for the next succeeding stitch.
The invention is not to be understood a being limited to the details of construction herein shown and described, as for cooperation with a different'form or differently-timed shuttle from that with which the machine herein partly illustrated is provided somewhat differently-located but oppositely-acting take-up pins or studs on the rotary takeup device or wheel might be employed. Also instead of. using two diametrically-arrangedtake-up pins or studs and a rotary take-up device or wheel comprising three separated disks, affording two thread-passages between them, as herein shown and described, the number of disks might be increased, and as by adding a fourth or even more, and in the case of the addition of the fourth disk a somewhat difierent arrangement thereof might be desirable or necessary.-
It will thus be understood that the invention consists, broadly, in a rotary take-up provided with a plurality of eccentrically-located takeup pins or studs preferably in combination with eccentrically-located slackcontrolling pins or studs for cooperation with the take-up elements in properly controlling the needle-thread at all times.
