IMPROVMENT iN GLOVE-SEWING MACHINES.
Specification forming part f Letters Patent No. 180,225, dated July 25, 1876; application filed January 24, 1876. A Y
To all whom Ait may concern:
Beit known that we, PETER E. GULLRAND- sEN and JOHAN C. RETTINGER, ot'Gopenhagen, Denmark, have invented a new and Improved Machine for Sewing Gloves, ot' which the following is a specification In the accom pan ying drawing, Figure l represents a vertical ylongitudinal section ot' our improved glove-sewing machine; Fig. 2, a detail side view ot' the actuating mechanism; Fig. 3, a top View of the machine; Fio. 4a bottom View of the gearing transmitting moanism of the cross-stitching device. Fig. 6 is a detail bottom view ofthe needle-bar-actuating cam; Fig. 7, a detail top view ot' the bobbin-tension device, Fig. S, a side view of the needle-bar, showing attachment ot'needle; and Fig. 9 is a side view ot' the rotating hook. Figs. 10 and 11 are face and back views of the stitch made by our machine.
Similar letters ot' reference indicate correspondin g parts.
'lhe object ot our invention is to construct a glove-sewing machine on the revolving-hook system, which produces with two threads astepping and cross stitch, that resembles and equals the best sewing done by hand, and makes the seams strong and durable.
The invention consists ot' glove-feeding cups, reciprocating needle-bar with tension devices, a rotating hook with bobbin and tension, and a compound mechanism for operating the crossstitching device. The horizontal actuating mechanism ot' the parts is inclosed below the table, and operated by a treadle, the glovei'eedingcups being run close to each other, or at some distance t'roni each other, to take hold or relinquish the work by means of a pressurespring and releasing treadle-connection.
In the drawing, A represents the supporting-tableI of our improved glove-sewinglmachine, which is placed on a frame similar to that ot common sewing-machines, and provided with two treadles-one to set the machine iu motion, the other to' control the glove-feedingcups. Theactuatingmechanismisarranged ina horizontal manner below the table, the
main treadle being connected to the same by the pi-voted treadle-rod a, which is pivoted t0 f and (1 are )laced inside of illars B and B,
J l l ot' whichv three are supported 011 the table, the central pillar B2 serving to carry the feed-shaft g2 and cup. Thev central and rear pillars B2 Bl are fixed in stationary manner to the table A. The front pillar B, however, is secured, by strong fastening-screws or otherwise, to a swinging'lever-frame, lL, a recess in the table admitting the adjustment ot' front pillar B. The 'lever-frame his ot' oval shape, as shown in Fig. 4, and hinged to bearings at the bot tom ot' frame A, a strong spring, h', acting ou the part of frame L opposite to the front pillar B, and forces thereby that end of the lever-frame down, raising thereby the front pillar B, and carryingthe rim ot' a loose'cup. B3, at the ripper end ot' the same against the rim of the revolving cup B4, applied rigidly to the central feed-shaft g2. A second treadle connects by its rod to a pivoted arm, i, that passes across the swinging lever-trame h, and raises the same .when the front part ot' the treadle is depressed, so that its rear part and rod are forced in upward direction. The spring L, acting on the lever-frame, causes the approach and tight binding ot' the cups, so as to feed forward the leather or otherlfabric placed between the same, the depression ot' the treadle separating the cups, and admitting the inserting and detaching ot' the work. The feed-cup B2 ot' the central shaft is revolved by a ratchet-wheel, l, at the lower end of the shaft, which is engaged by a pawl, ll, of an angular spring-acted arm, l2, that is acted upon by an eccentric or cam, Z3, of the rear shaft, (shown il: Fi". 4,) so that each revolution ot' the shaft moves the ratchet-wheel one tooth, and feeds thereby the cups and leather forward for a stitch. The upper circumference or rim of the cups is made parallel, or nearly so, and slightly roughened or milled, for the purpose of firmly holding the fabric to be sewed, and feedin g the saule to the stitchingneedle. f
The shaft of the rear pillar serves the twofold purpose of actuating the horizontal needle-bar O, which is guided in a square frame, F, at the top of the pillar, and reeiprocated by the eccentric pin m of a cam-wheel, G, keyed to the rear shaft, and engaging a curved slotted piece, a, of the needle-bar. (Shown in Fig. 6.)
lhe cam-wheel Gr is shown in Figs. 1 and 5, and is made of an upper and lower section, of which each is peculiarly formed-the lowerone to engage an angular arm, o, pivoted to frame F, .the upper to engage a similar arm, p, pivoted at the front end of frame l.
A fixed arm, 0I, is keyedto the upper Aend of the pivot of arm o, and connected by a loose balland-soeket joint to the rear end of the eross-stitehing lever E, which is further applied to the fixed arm ol by a spiralspring, 02. An ar|n,11,is 'attached to the upper end ofthe pivot ofthe angular piece p, and is provided at its end with a forked bearing,rp2, to which the lever E is loosely fulcrunied to slide readily by a projection below the fulcruln to one side or the other of a raised part or earn, p3, otl the bearingpz. y
A springzp, bears on the upper partof lever E, and retains the saine in contact with the forked bearing. The don-ble cam-wheel Gr imparts, b v the joint operation of arms 0l and p1, a compound motion to the cross-stitching levell E, which is thereby enabled to take up, by its peculiarly-spurred front end, (shown in Figs. l and 3.) the thread from the bo'obin in `the front cup, carrying the saine across the edge ofthe material down in the feed-cup 152, and forming there a loop, through which the needle passes. The erossstitehing apparatus returns then to its original position, ready for the next stitching. Y
The needle is attached by a fastening-ring and set-screw to the front end of the sliding needle-bar, the thread heilig taken from a` common spool placed on a side arin of the square frame F.
lhe thread is guided over a suitable tension, q, back to a take-up device, q1, that is applied to an arm at the rear pillar, and operated by a connectinglin k, q2, of the needle-bar. rlhe thread is then passed forward in a channel, o', of the fra-111e F to the needle, the said take-up serving to close the stitch after the loop has been formed by the rotating hook l) ofthe front shaft.
The central dishing part of the rotating hook, which is made in the nature 'of the hook used in the Wheeler 8L Wilson machine, carries a bobbin, D', that provides the second thread for cross-stitching the material. bobbin D is also provided with an adjustable tension device, H, which isshown in Figs. l and 7, and secured by a set-screw to a support or arm of the front pillar. A central disk of the bobbin-tenson bears on the same,
and is set thereto by a lever-arm with spiral spring and regulatingnut.
An additional cog-wheel, I, with springacted sliding shaft and nut I', may be used for starting the machine.
The rotating hook and bobbin revolve twice with each stroke ofthe needle, for the purpose of assisting in forming `the stepstitch, that sews the edges ofthe fabric together, `and the cross-stitch, that binds across the edges ofand producing an elegant anddurable stitching of the fabric.
Having thus described our invention, we
` claim as new and desire to secure by Letters 1. The machine for sewing gloves herein described, consisting, essentially, of a horizontaily-reciprocating needlebar, (J, a rotating hook, l), with bohbintension, a crossstitching lever, E, and the glove or fabric feeding oups 133 B4, all constructed and relatively arranged substantially as herein shown, to operate in the manner set forth.
2. rlhe combination of the vibrating arm o 0l, movable angular piece 1J, and forked bearing 112 with the double cani G and crossstitching lever E, as and for the purpose set forth. p
3. vTheeoinbination ofthe horizontallyrotat ing hook l), bobhin D', and tension device 1I with the feeding-cup B, front pillar B4, horizontally-reciprocating needle-bar C, crossstitching lever E, and revolving feeding-cup B4, as and for the purpose set forth.
