SEWING-MACHINE.l
SPECIFICATION forming part of Letters Patent No. 455,691, dated July 7, 1891,.
Application led December 16, 1890. Serial No. 374,874. (No model.)
.To all w/wm it may concern: Be it known that I, CHARLES S. REED, o Boston, county of Suffolk, State of Massachu-v setts, have invented au improvement in Sewing-Machines, of which the following descrip-k tion, in connection vwith the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.
This invention has for its obj ect to provide a sewing-machine of the wax-thread variety, using an awl and hooked needle, with means for moving laterally the material being stitched while the needle and awl are out of the material, whereby an overedge-stitch is made with a single thread.
The machine herein to be described is Very useful for applying a fibrous or cloth binding` or edge to a wooden or other frame for a slate,
v2o and it may be used to great advantage in overstitching other heavy articles.
In the machine to be herein described the stitch-forming devices, including the needle,
cast-off, awl, and thread-guide, are substan- 2 5 .tially as common. With these common parts I have combined a work holder which is moved laterally by a cam on the main shaft below the bed-plate, the said holder consisting,vessentially, of a bottom or base plate, a 3o presser-foot or equivalent capable of vertical movement, a link connecting it with a stand, av stud on `the said plate, and preferably a gage attached to and moving with the said work-holder. The face of this gage is notched or cut out equal to the length of the longest stitch to be made, so as to let the needle in its horizontal or feeding movement move outside the edge of the material.
The particular features in which my inven- 4o tion consists will be hereinafter described, and pointed out in the claims at the end ofl this specification.
Figure l is aefront end elevation of a sewing-machine embodying my invention, the material being omittedfrom under the presserfoot; Fig. 2, a side elevation partially broken away; Fig. 3, a top or plan View of the workholder below the irregular dotted line oc, Fig. 1; Fig. 4, a detail in side elevation of the parts shown in Fig. 3; Fig. 5, a top or plan View 5o like Fig. 3, but with the parts in different positions. Figs. G and 7 show the two cam-hubs developed. Fig. 8 shows material bound and overstitched by the machine herein to be described, and Fig. 9 a detail showing the guide `55 f2 detached.
The frame-work consists, essentially, of the casting A, the post A', the plate A2, the overhanging arm A3, and head A4. The head has bearings for the awl-bar B, having the awl l) 6o and the presser-bar B. The casting A is provided at its front end with a dovetailed groove (see Fig. 2) for the reception of the feed-slide B2, provided with the guide B3, in which reciprocate the needle-bar B4, having a hooked needle b4, and a cast-off B5, having secured to its upper end any usual cast-off.
C is the thread-guide shaft, having the at# tached thread-guide c.
The awl-bar derives its vertical movements 7o` from an elbow-lever B7, pivoted atBS. The parts so far speciiically referred to by letter are old and common inwell-known waxthread sewing-machin es for leather-work, and in practice they will and may be actuated in any usual manner to cause the awl to penetrate the materialfor the passage of the hooked needle through the material and to enable the needle to feed the material, and in practice the presser-foot will be automatically lifted 8o by usual devices acting on the lever b5 to lift it from the materialduring the time that the needle in the material acts to feed lthe same. These parts, being old and common in the socalled New England wax-thread sewing-ma- 8 5 chine, need not be herein more fully described further than to say that the thread on its way to the thread-guide c maybe waxed, oiled, or treated in any usual way and be subjected to the action of any usual tension de- 9o vice or take-up.
The casting A has suitable bearings for the main rotating shaft D, havinga cam B9, shaped, as best shown at 2, Fig. 7, to afford a slight dwell in the awl-bar, as when the holder to be described is being shifted laterally. The main shaft has applied to it a second cam-hub D', which receives a roller or other stud D2, ex-
tended downward from the under side of the bottom plate e, constituting part of the holder for the material. The other effective part of the holder consists of a presser-foot c', having, as represented, a stud-screw e2 (see Figs. l and 3) and a link c3, connected with the said l screw, and a stud-screw e4 in a stand e5, at-
tached to the said bottom plate. This bottom plate also has connected to it by screws f the I binding m of felt or other desired fibrous material. The machine herein described may, however, be used to overstitch any heavy materials wherein it is desired to cover the edge with a single thread stitched eitherpwith or without a binding. The dog g, held in place by the screw g, serves to keep the bottom plate down in proper place in its guideways in the table-plate A2.
In this invention the gage]2 is attached to and so as to travel longitudinally with the work-holder, and the edge of the material to be stitched is placed against the edge of the gage.
Assuming that the material to be stitched has been placed upon the work-holder next the face of the gage f2, the presser-foot at such time being lifted in usual manner and the binding m" having been placed between the edge of the material to be overstitched and the face of the edge-guide, and that the work-holder has been drawn back fully to the right, as in Figs. l and 2, andthe machine started, the awlb will descend to` punch a hole nearly through the material and through the binding thereon, and then the awl will commence to rise and the needle will follow closely the pointof the awl and complete and rise through the hole made thereby and above the presser-foot, at which time the presserfoot will be slightly lifted and the needle-bar will be moved in usual manner by the usual devices common to needle-feeding machines to feed the material for the length of a stitch. The material having been fed the length of a stitch, the presser-foot closely descends again upon the material, it having a rising motion given to it in any usual manner to enable the vfeed to take place, and the threadguide is then moved forward, so as to deliver its thread into the hook of the needle, when the latter commences to descend and draws a loop of needle-thread down through the material, the thread-guide being retracted in usual manner and by usual devices common to wax-thread sewing-machines as the needle completes its descent. As soon as the needle descends through the material, taking with it a loop of thread which it yet holds, the workholder, by or through its actuating-cam D', is moved to the left, the needle yet holding the loop of needle-thread below the material, and the movement of the holder to the left having been completed and the needle-bar having in the meantime again been moved forward toward the front of the machine into its starting-point preparatory to rising the needle is again raised, yet holding upon its shank'the last loop of thread pulled down by it and the needle is again moved in the direction of the feed of the material; but at this time the needle does not enter the material, but stands at one side of the material with its hook above the presser-foot, as before. During this second backward movement of the needle. in the direction of the feed the needle does not move the material, but it does act upon the needle-threadbetween thethreadguide and the material at the stitch-making point and pulls the said thread back in the direction of the feed, and the needle having completed its backward stroke the threadguide again supplies its thread to the needle, which latter pulls a second loop of thread down through the loop then on its shank, the second loop to be pulled down lying, however, outside the edge of the material. The needle having completed its descent as before, the work-holder is again moved, this time to the right to place the material again in position to be penetrated by the awl and needle. The only time that the presser-foot is lifted from the material is when the needle in the material is moving it to feed the same for the length of a stitch. At all other times the presserfoot bears upon the material and holds it down in place upon the lower member e of the workholder. The cam-groove in the cam B9 is of such shape at the points 2 2 as to give to the awl a slight dwell or to slow down its movement sufficiently to permit the work-holder to be moved laterally without interfering with the awl, this slight dwell or slowing down of the speed of the awl adding very materially to the value of my invention.
I claim- A sewing-machine containing the following instrumentalities, viz: an awl-bar having an awl, a lever to move the said awl-bar, the rotating shaft I), having a cam B9, to actuate the said lever, and a second cam D', athreadguide, a needle-bar, a hooked needle,a co-operating cast-off, a presser-bar, and a workholder consisting, essentially, of a presser-foot connected with the presser-bar, a bottom plate e, the link e3, pivoted thereto, the edgeguide attached to the said bottom plate and havingv a cut-away portion in its face, and a stud or finger attached to the bottom plate and actu- IOO ated by the Said earn D, the needle moving name to this specification in the presence of in said eut-away portion in itssecond ascenty two subscribing Witnesses. in the direction of the feed, but not in themal terial, to' thereby engage the needle-thread CHARLES S.
