SEWING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 432,449, dated July 15, 1890.
Application tiled November 25, 1887. Serial No. 256.060. (Model.)
To all whom it may concern: y
Be itknown that I, JAMES STEWART, Jr., a citizen of the United States, residing at Yonkers, in the county Of Westchester and State of New York, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specilication.
1 My invention relates to a machine adapted not only for ordinary straight. sewing, lout also to fancy, ornamental, overedge, and eyelethole sewing.
lts object is to produce a simple and effective machine, readily adjustable, and adaptable to the particular stitch to be made, which end I attain by a novel organization of instrumentalities.
The subject-matter claimed is hereinafter specilied. Unless otherwise designated the parts are of usual construction.
My improved organization involves the lateral movement ortraverse of the stitch-forming mechanism in alternately-opposite directions across the line of feed of` the goods. Vhere the loop is formed on the under side of the goods by means of a rotating hook, I form on the front face thereof an annular fiange, the working-edge of which is inclined to the plane of its rotation or the line of traverse of the needle, so as to deflect the thread relatively to the path of the needle at proper intervals in co-operation with a pin or stud lying in close proximity to the pathot` the needle and oscillating laterally therewith and with the hook to control the thread in forming the loop. The driving-wheel, the driving-shaft, the rotating hook, the looperstud, and the needle-bar, in addition to their usual movements, all reciprocate transversely to the line of feed, being mounted in or earried by a plate or frame sliding on the main frame and provided with a bearing einbracing a journal on the driving-shaft., which carries a pinion gearing with acorresponding wheel carrying a detachable pattern-cam connected with the frame by adjustable levers, so that various designs and kinds of stitches may be produced by varying the relative movements of the parts.
The accompanyingdrawings show so much of a single-thread sewing-machine embodying my improvements as is necessary to illustrate the subject-matter claimed.
Figure 1 shows a front elevation of the machine or that side on which the pattern-cam is located with the cover of the pattern-cam removed and the table and adjacent parts in section. Fig. 2 is a similar elevation ofthe rear or opposite side of the machine. is a view in elevation of the stitch-forming end of the machine with the table in section. Fig. 4 is a vertical transverse central section on the line c x of Figs. 1 and 2, looking toward the driving-wheel end of the machine. Fig. 5 is a plan of the presser-foot ordinarily employed; Fig. 6, a plan of part of the table; Fig. 7, a plan of the feeding and loop-forming mechanism under the table. Fig. S shows a view in elevation, partly in section, ofthe stitch-forming mechanism detached, with the parts in the position they occupy when the needle begins to rise in advance of the medial line of the needle; and Fig. 9, a similar view of the same parts during the corresponding operation in their retracted position or that nearest the driving-wheel end of the machine. Fig. is an outline face view of a patterncam adapted to produce the stitch shown in Fig. 17, and Fig. 11 a similar View of a pattern-cam adapted to produce the stitch shown in Fig. 18. Fig. 12snows a plan of a pressen foot adapted for overedge stitching. Fig. 13 shows a plan, and Fig. 13 a vertical transverse section, of a presser-foot and guide adapted for forming eyelets. Figs. 14 to 23, both inclusive, illustrate some of the various kinds of stitching which my improved machine is capable of producing. Figs. 24 and 25 are perspective views, on an enlarged scale, of my improved stitch or loop forming mechanism.
The drawings show a G-shaped stationary or main frame a. A U -shaped plate or frame is provided with horizontally-elongated slots near its upper front and rear ends, which slide on guide-pins b b2 on the upper arm of the main frame a, thus leaving the plate b free to slide horizontally and longitudinally thereon. A needle-bar c2 reciproca-tes vertically in bearing-blocks c c on the front endl IOO v cam j.
of the sliding frame l) and carries a needle c3 on its lower end. A block c4, pivoted on the needle-bar between its bearings, slides in :L horizontal slot in the free end of an arm d, rocking on a pivot d2 on the main frame ct and having a spherical stud d3 on its short arm, connected with a similar eccentric c on the driving-shaft E by a connecting-rod F. A guide-block c5, secured to the rear side of the needle-bar, works in a vertical slot in the slide-frame, thus preventing the needlebar from turning axially in its bearings. A bearing-arm f2, rigidly secured to and pendent from the sliding frame or plate7 em* braces a grooved journal in a collar j", fixed on the driving-shaft, which shaft is thus caused to slide longitudinally or move endwise in its bearings a c2 in the main frame coincidently with the reciprocating movements of the slide-frame or plate in its bearings. The driving-shaft also turns freely in its bearings, being driven by a belt encircling a driving wheel or pulley e2 thereon. It also moves freely endwise through a bevelpinion g, mounted in a fixed bearing a3 in the main frame in such manner as to rotate freely therein in a fixed plane or without endplay. Pins f3, projecting from the face of the grooved collar f parallel with the drivingshaft, enter holes in the bevel-pinion, thus forming a feather, which causes the pinion and collar to rotate together, while leaving the latter free to move to and fro relatively tothe former. A bevel-wheel g turns on a stud g2 on the main frame and :meshes with this bevelpinion g. A face-cam g3 is secured to or formed on the outer side of the bevel-wheel g. A lever 71I on a short shaft h', rocking in abearing on the main frame, carries on its free end a guide-pin or friction-roller working in the cam g3. An arm 7L2 on the rockshaft is embraced by the fianges of an adjusting-block h3, pivoted in a slide-block e, adjustable vertically in a slot t in the sliding frame. An adj Listing-screw i2, provided with a milled head t and turning in a bearing in the sliding frame, passes through this slideblock, and thus adjusts it higher or lower in the slide-frame, the flanged block 71.3 sliding correspondingly on the rocking arm h2. This adjustment correspondingly regulates the throw or amount of lateral reciprocation imparted to the sliding-frame and its connected parts by means of the face-cam, the range of movement of course being greater the farther the adjusting-block is set from the axis of the rock-shaft 7L. Vhen the center of this block coincides with the axis of that shaft, the slide-frame will remain unmoved, and the mechanism will be in condition for ordinary straight sewing.
The article to be stitched is held in proper position by a presser-foot having the usual barj, movable vertically endwise in the main frame, its depressingspring j', and lifting- Special presser-feet are secured on the lower end of the bar j for different styles of sewing. The presser-footj3, (shown in the main views and in Fig. 5) has a triangular opening, through which the needle passes. Other forms of presser-feet will hereinafter be described.
The feeding device Z is shown as consisting of three sets of parallel teeth working through three slots in the throat-plate m of the table m and carried by a bar Z, actuated byan eccen tric e3 on the driving-shaft, and controlled in its movement by the ordinary eccentric-stop Z2 at the front end of the machine, while its other end slides in the usual guides. The feed operates in a fixed relation to the main frame, while the eccentric partakes of the endwise movement of the drivin g-shaft, and is accordingly elongated to an extent sutiicient to accommodate this movement-that is to say, the eccentric both rotates and moves endwise in the feeding device to actuate it. The throatplate m is adapted to slide in grooves in the table, so as readily to admit ot' its insertion or removal or replacement by others of special construction. Fig. 6 shows it as provided with a triangular opening m2, through which the needle passes, and with three parallel slits, through which the feed-teeth project, two of these slits being short and immediately belhind the needlebpening, and the third and longer one extending alongside the opening.
A bar n, extending forward from the sliding ing frame u nder the table, carriesat its forward end a looper-stud or thread-guiding pin n/,located immediately below the table about the level of the top of the rotary hook in advance thereof-that is, on the side opposite from the dri vi n g-wheel--an d proj eetin g backward from the front side of the machine or that on which the face-cam is located. The needle reciprocates in the space between the forward face of the rotary hook and the looper-stud, the free end of which points toward the feed-bar. This looper-stud or thread-guiding pin controls the loops formed by the rotary hook o and presents them properly to the needle when the latter and the stitch-forming devices are in the positions shown in Figs. l and fl-that is, in their retracted position or that nearest the driving wheel. The rotary hook 0 is mounted on the forward end of' the elongated eccentric c", formed on the drivingshaft E, and is provided with an annular or cylindrical thread-guiding flangel or rim o', the forward or operative edge of which is inclined or canrshaped relatively to its plane of rotation on the side next the wheel, its greatest projection being just behind the point of the hook relatively to its direction of rotation, just behind which point the cam suddenly inclines away from the needle to a point opposite the other end of the hook, whence it gradually widens to the point of greatest extension above mentioned. The relation of the parts is such that the thread is taken from the needle just as it begins to rise by the hook TOO IIO
o, passing between the back of the hook and the flange, subjecting it to increasing friction I or pressure during the rotation of the hook in forming the loop, which is then presented to the needle for its passage therethrough in making` the next stitch, the drop-off part of the flange assisting in controlling the thread in properly presenting' the loop to the point of the needle when the stitch is being formed, with the parts in the advanced position or that farthest from the driving-wheel. Figs. 2 and S.)
The stitch produced by the mechanism organized, as shown in the main views of the the high part of the cam or that farthest fromits axis, while the opposite stitches are formed when the roller is in the opposite portion ot the cam, the feeding of the goods taking place between each stitch when the needle is out of the cloth, as usual. Fig. 15 shows the reverse side ofthe stitch shown in Fig. 14 and the manner of interlocking the threads on that side. Fig. 10 shows the reverse side of this zigzag stitch with the looping and `interlocking of the threads thrown to one side of the medial line by varying the tension on the thread. i
A great variety of stitches may be produced on this machine by changing the gearwheel g and face-cam g3. It, for instance, a wheel be substituted having the proportions of three to one relatively to the driving-pinion g and carrying a cam g5, Fig. 10, adapted to move and hold thc lever h in one of its positions for a third of its revolution and to move and hold the lever in the other position for two-thirds of its revolution, the stitch shown in Fig. 17 will be formed. rlhe use of a wheel having the proportions of four to one in relation to the drivingpinion g and carrying a two-throw cam g, Fig. 1l, will produce the stitch shown in Fig. 18. By changing the form of the cam on this four-to-one wheel the needle may be caused to penetrate the goods, first, on one side of the medial line; secondly, on that line; thirdly, on the same line, and, fourthly, onrthe opposite side of that line, thence returning to the opposite extremity of its movement to repeat. th ese steps, forming the stitch shown in Fig. 19. Another cam on the same wheel will produce the pattern shown in Fig. 20, the first stitch being on one side of the medial line` the second on the line, the third to the opposite side of the medial line, and-the lfourth on the line again.
It will readily be understood from the foregoing description that an endless variety ol patterns and stitches may be produced by simply changing the number of teeth of the (See the needle-hole cut away at one edge.
pattern gear-wheel g and the relations of the face-cam g2 relatively tothe driving-pinion g.
lt will also be seen that the form of each patoveredge stitch, so as to1 lie on the extreme edge of the goods or on either side thereof, thus producing varied and pleasing effects and adapting said stitch as a binding. In working this overedge stitch on this machine I prefer to use a presser-foot 71;, Fig. 12, withA The gear-Wheel g. and face-cam g3 are used to produce the stitch shown in Figs. 21 and 22, the needle of the machine being therebyT caused. alternately-to pierce the goods near one edge and to form a stitch outside of but near said` edge, the inclined or cam flange 0, surrounding the hook 0, assisting to form the stitch and throw the loopings under thc edge, as shown in Fig. 22. l
To adapt t-he machine to bind eyelet-holes, as in Fig. 23, a plate q is substituted for the plate m, ordinarily used. `rlhis plate q is proupwardly from the plate at one side of the needle-opening. rlhe goods p2 are placed upon the table with this flange p extending. through the hole to be bound, said flange acting as a guide around which to turn the goods. This rotation is accomplished by ythat part of the feed-teeth lying alongside the needle, the goods being pressed thereon by a roller r on a stud projecting from a presserfoot 7c', substituted for the one above described. lVhen this guide and rotary presser-foot operate in combination with the twothrow cam g3, (shown in the main drawings,) the needle alternately pierces the goods set` over the semi-cylindrical guide q on one side of said guide, and then passes through the guide and the holein the goods. I As the goods are partly rotated each time the stitch is made by the feed l and the roller o of the presserfoot, the stitches are formed radially around the hole, as shown in Fig. k23.
It will be seen from the foregoing` description that under my improved organization the driving-wheel, the driving-shaft, the rotary hook, the looper-stud or thread-guiding pin, and the needle, in addition to their usual movements, are all reciprocated transversely to the line of feed during the formation of the stitch bythe action of the pattern-cam g3 and its connections with the slide-frame, and that these traversing movements are always in the same vertical and horizontal planes, in contradistinction to prior machines, in
IOO
tion, organization, and operation of my improved sewing-maehine, what I claim therein as new and as of my own invention is- 1.
