SEWING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 465,743, dated December 22, 1891.
Application tiled December 18, 1890. Serial No. 375,109. (No model.) l
T Ol/ZZ whom, t may concern:
Be it known that I, RUSSEL G. WooDwARD,
a citizen of the United States, residing `at lVaukegan, in the county of Lake and State of Illinois, have invented a new and useful Improvement in Sewing-Machines, of which the following is a specification.
My invention relates more especially to an improvement in the class of sewing-machines adapted by means of a looper and mechanism for actuating it both back and forth and laterally to form loops in the thread at the needle or needles, and thereby link the thread to produce a concatenated stitch.
In sewing together two thicknesses of material which it is desired shall be capable of being opened out tiat at the seam a degree of elasticity or give is necessary in the stitch to permit such iattening out of the material.
The object of my invention is to provide means for use with sewing-machines, particularly of the class mentioned7 whereby a sufiicient amount of yield or slack shall be provided in the links of the thread in forming the stitches to afford in the seam the desired degree of elasticity referred to.
To this end my invention consists in forming in the throat-plate and the presser-foot each two needle-holes and an intermediate 3c rigid projecting tongue, the needle-holes and tongue on the presser-foot respectively aligning vertically with their counterparts on the throat-plate. By these means 'the thread in being passed by the action of the needle or needles through the needle-holes on opposite sides of the tongues and through material to be sewed interposed between the presserfoot and throat-plate forms, with the looping mechanism, a concatenated stitch, and in forming the latter crosses the thread over the two tongues. Thus the desired slack is aiorded in the stitch, and as the stitching proceeds the parts of the thread crossing the tongues are slid off the ends of the latter by the feed in feeding the material.
The only'feature in a sewing machine which I claim as myinvention in the present specification is that of the slack-producing appliance formed of the tonguesin the presserfoot and throat-plate projecting from between the needle-holes. This mechanism may be applied to any sewing-machine having needle-actuating mechanism, a looper, and looperactuating mechanism suitable for use with it, such mechanisms as are represented in the 5 5 accompanying drawings as co-operative with my said invention being shown and described inLetters Patent of the United States hereinafter more definitely referred to. Even the peculiar stitch illustrated and hereinafter de- 6o scribed is not novel, except as to the feature of slack provided in it.
Referring to the drawings, Figure 1 is a View in side elevation, partly sectional, of a sewing machine provided with my improvement. Fig. 2 is a section taken at the line 2 of Fig. 1 and viewed in the direction ot' the arrow. Fig. 3 is a section taken on the line 3 of Fig. 1 and viewed in the direction of the arrow. Fig. 4 is a perspective View in the 7o nature of a diagram, showing the presser-foot provided with the tongue and needle-holes with material in place to be sewed and the needle making the stitch. Fig. 5 is va similar view of the portion of the throat-plate provided with the tongue and needle-holes.
`Fig. Gis a cross-sectional view through the presser-foot and throat-plate and th rough the rigid tongues thereon, showing the formation of the slack on the tongues in stitching 8o through the material being sewed, the section being taken at the line 6 of Fig. 4. Fig. 7 is a perspective view in the nature of a diagram representing in exaggerated size the stitch produced by the mechanism illustrated.
With the exception of the tongues and needle-holes in the presser-foot and throatplate, the parts of the mechanism presented in the drawings are shown and described in Letters Patent of the United States, No. 9o 299,568, to Muther and Dearborn, dated J une 3, 1884, and No. 401,294, to Muther and foodward, dated April 9, 1889. Hence they need not herein be more definitely referred to than is required to enable their (3o-operation with 95 my said improvement to be comprehended, and I do not limit the use of my said improvement in connection with the particular mechanism illust-rated, since it is adapted for use in chain-stitch sewing-machines generally, too whether employing one or two needles each, having analogous mechanisms for producing a concatenated stitch. It may also be used with lock-stitch sewing-machines, and the terms of the appended claims are intended to include its construction with the shuttleform of sewing-machines.
A denotes the frame provided with an Yover hanging arm A, having a stud A2, upon which is pivoted avibrating arm A4, actuated through the medium of a link A5, connecting -it with an eccentric A6 upon-the lower shaft B of the machine, the said shaft being provided at its front end with suitable cams or eccentrics for actuating the feeding mechanism, substantially as described in the aforesaid Letters Patent No. 299,568.
B is a pitman pivoted at one end to the lower end of the arm A4 and jointed at its opposite end to a looper-frame a, pivoted at a upon a rocking frame a2. The looper-frame has adjustably connected with' it the looper having at its heel a slotted eye, in which is led the under thread, the said thread being carried along in a groove in one side of the looper and emerging from the hole Z9 in the forward end thereof, and behind which on one side (not shown) is a shoulder to catch the thread in the sewing operation. This looper has a movement into thev loop of the needlethread, and then rocks across the path of vertical movement of the needle c in the direction of the feed and back again toward the rear of the machine, so that the looper and needle co-operating together make a stitch.
' The medium for effecting the lateral oscillation of the looper-carrier at proper intervals is shown in Fig. 3, and comprises the eccentric n upon the main shaft B, working in the fork of a forked armm on a pivotal support upon the frame A. These various parts are likewise shown and described in the aforesaid Letters Patent No. 299,568.
'The following-n amed parts and their operation are shown and described in the aforesaid Letters Patent No. 401,294: The shaft B, carrying the pinion C, engages the gear C. The cam C3 on the gear C is engaged by a roller D at one end of the elbow-lever D', pivotally supported on the bracket D3 and jointed by a link D4 to the arm d, attached by screws cl to the arm e of the guide e for the needle- -bar e3,which guide is pivoted to oscillate To afford my improvement I provide in the presser-foot E two needle-holes r and q at opposite sides of the aforesaid line parallel with the direction of feed and in the lines of the verticalplay of needle c, and between the needle-holes I provide a rigid ton gue p. In the throat-plate F, I provide the two needle-holes r and q toalign vertically with the needle-holes r and q, respectively, and between them the rigid tongue p to align with the tongue p.
As will be readily understood, the thread carried by the needle in the oscillations of the latter across the plane of the tongues is caught by the looper below the tonguep, thereby forminga series of vertical loops about catenated stitch, which loops afford the slack the two tongues in the formation of the conto produce the desired elasticity in the stitch,
and are moved off the tongues toward their free ends with the material o being sewed by the action of the feed G upon the material.
The peculiar stitch formed -by the particular mechanism illustrated as co-operating with my improved slack-producing means is represented in Fig. 7; but as it presents no novelty,l except as to its slack structure, due to being crossed about the tongues, and will be readily comprehended by those skilled in the art to which my invention relates, the stitch need not herein be accurately described.
That I claim as new, and desire to secure by Letters Patent, is-
1. In a sewing-machine, and in combination with a vertically and laterally moving needle and a looping mechanism, a presserfoot having an opening in its base, a tongue extending into said opening, thereby forming IOO two needle-holes, and a throat-plate having an opening corresponding to that in the presserfoot and provided also with a tongue extending into the said opening, substantially as described.
2. In a sewing-machine, and in combination, a vertically and laterally movable threadcarrying eye-pointed needle, a presser-foot having an opening in its base, a tongue extending into said opening, thereby forming two needle-holes, a throat-plate having an opening corresponding to that in the presserfoot and provided also with a tongue extending into said opening, means for moving the needle vertically and reciprocating it laterally from one side to the other of the tongues, a looper, and mechanism for moving it positively in the four directions, substantially as described.
