J. H. CHENOWETH SEWING MACHINE Patented July 14, 1925.
UNITED STATES JOI-IN H. CHENOW'ETH,
OF CHICAGO, ILLINOIS.
SEWING MACHINE.
Application filed vMay 4,
To all whom t may concern.'
Be it known that I, JoHN H. CHENownTH, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Sewing Machines, of which the following is a full, clear, concise, and exact description.
My invention relates to sewing machines and, generally speaking, resides in the provision of improved cloth feeding mechanism supplementing the cloth feeding mechanism commonly forming parts of sewing machines and serving to have a feeding action upon the cloth which differs in extent from the feeding action of the main feeder.
If the 'supplemental feeding mechanism includes a tucking tool that engages the cloth the cloth is folded into tucks, the tucking tool having a greater travel than the main feeding tool. If the cloth is in the form of a tape whose threads are woven upon the bias and the supplemental tool employedis a spreading tool instead of a tucking tool the tapel will be widened, the spreading tool again having greater travel than the A main feeding tool.
The tape or cloth is sewed along its length, that is the direction in which the cloth is being fed, as it is shaped by the joint action of the main feeding tool and the selected supplemental tool whereby the shape imparted t the cloth by these two tools is preserved.
I will explain my invention more fully by reference to the accompanying drawings in which Fig. 1 illustrates the preferred embodiment thereof as employed in one of many standard makes of sewing machines; Figs. 2 and 3 are sectional views taken respectively on lines 2 2 and 3 3 of Fig. 1; and Fig. 4 is a perspective view, somewhat diagrammatic, illustrating parts of a standard sewing machine in dotted lines and my attachment in full lines.
Like parts are indicated by similar characters of reference throughout the different figures.
The main shaft 1 of the machine is driven by means of any suitable mechanism, there being illustrated belt driven sheaves 2 and 3 of different diameters, fixed upon the shaft and a hand wheel 4 also fixed upon the shaft. An eccentric 5 is fixed eccentrically upon the shaft and turns within a circular opening formed in the block 6 that is an 1923. serial No. 636,628.
integral part of an arm 7. This block is interposed between and is in sliding relation with the jaws 8 and 9 that are integral parts of an arm 10. The base of the arm 10 is bifurcated asV indica-ted at 11. The base portions 11 of the arm 10 are journaled upon a shaft 12 fixed upon an upright link 13 rigidly assembled with a shaft 14 at its base. The Vends of this shaft are journaled in fixed bearings formed in or carried by the stationary frame 15 of the machine. The link 13 has an upright arm 16 rigid with respect thereto and which is formed 'with an arcuate slot 17 therethrough. The main feeding tool 18 is normally rigid with respect to the arm 10 although adjustable thereon as is vunderstood by those skilled in ythe art.
The action of this'well known mechanism need not be explained in detail, it suflicing to say that the movement of the main feeding tool 18 in the direct-ion of the feeding movement may be varied in extent by adjusting the place of assembly of the arm 7 with the arm 16 of the link 13. For this purpose the shaft 19 upon which the arm 7 is journaled is provided with a clamping nut 2O which positions this shaft in any selected place along the arcuate slot 17.
Having thus outlined the well known mechanism, illustrated by dotted lines in Fig. 4, and which happens to form a part of the lVillcox and Gibbs sewing machine, I will now describe my improved attachment whereby any desired supplemental feeding tool, such as the spreader 21, may be associated with the main feeding tool 18.
In accordance with my invention the supplemental feeding tool is actuated by the ksame eccentric 5 that operates the main feeding tool 18. In the preferred embodiment of the invention this eccentric operates the supplemental feeding tool through the intermediation of the arm 7, the arm 16 and the link 13. To this end I assemble another arm 22 with the link 13 and bring this added arm into actuating relation with the supplemental feeding tool 21 in the manner to be described. In order that the arm 22 ma be most conveniently assembled with the link 13 I form said arm with a base portion 23 which is assembled with the link by means of screws 24. The arm 22 is formed with a straight slot 25 through which a shaft 26 is extended, this shaft being adjustable along the slot and provided with a llt) "at its other end is'journaled iipon a shaft 29 that passes through an arcuate rslo't '30 formed, in `still another farm Y31 Awhich is` journaled upon a shaft S2 turning in bearings 33 that are fast upon the frame of the machine. yZll'ieshaft A29 may beheld in any position 'along the slot 30 'by 'means of the clamping device 84.
The supplemcmtal `tool illustrated is the spreader 2l which is journaled at one end upon an upper portion of the arm 8.1 and whose work engaging end reciprocates upen a cloth positioning plate 35 with which this end is held in engagement by vmeansof a spring 36. By means of the mechanism illustrated the working end of `the supplemental feeding tool moves in the 'direction of feeding movement of the main feeding travel so that the tape or other c'loth operated upon will have its shape modified.
lf the supplemental tool is a spreading tool and the cloth operated 'upon is a tape whose weaving is on the bias; the tape will be spread.M Whatever the shape imparted toYV the 1cloth bythe supplemental fe'effing tooli such shane fis .preserved 'by 4a lnngitudiknal row of stitching uponk the tape 37` effected by the needle f'which operates upon the cloth that passes between the presser foot 39 vand the main feeding tool 18 land also between vthe cloth supporting plate 35 and supplemental tool S21.
By the mechanism illustrated the extent of feeding travel ofthe supplemental feeding tool may be widely varied to ysuit the nature of the work which'thiis tool is 'to accomplish.
While I have herein shown and particularly described the preferred embodiment of my invention I do not Wish to be limited to the precise details of construction shown as changes may readily be made 'without departing from the spirit of Vmy invention, but having thus described my invention I claim as new and desire to secure by .Letters Patent the following 1. A sewing machine including a main operating shaft; an eccentric upon this shaft; a block upon -theecce-ntricl; an arm with which the block is in sliding engagenient; a main feeding tool upon the arm; a pivoted link upon which said arm is mountlturn n jai'fm p p connected at one end with the latter arm and terminating in the aforesaid block at its 'thislinl' having' aiiarn Vthere'en 1 j v. aren and swinginglyw other lend;aisecond arm upon saidlink; an j' arm adjustable along and swingingly connected at one end with the latter arm; another swinging arm with which 'the re-; maining end of the last aforesaid arm is swingingly connected and also .adjustably yconnected along the same; and a supplemental feeding tool maintained thereby in eo-operative relation with the main feeding tool.
2. A sewing machine including 'a main operating shaft; an eccentric Vupon this shaft; a bloclcupon the eccentric; an arm 'with which thel block .isin sliding engagement; a main feeding tool upon the arm; `a lpivoted link upon 'which said'arm jis mounted to turn, this 'link 'having an arm thereon; an arm swingingly connected at one end with the rlatter arm and terminating in the aforesaid block at its other end; a second arm upon said link; an armswingin'gly vconnected at one end with Ythe latterY arm: an- ,w
'swiii'gingly connected; and a supplemental feeding tool maintained tl'iereby in co-operative relation rwith lthe .main feeding tool..
, 3. A sewing'machine including a main operating shaft; an yeccentric upon 'this' shaft; av block upon the eccentric; an arm with whichthe block is in sliding engagement; a main feeding tool upon the arm;`ia pivoted llink upon which said arm is `mounted to turn; an arm Aswingingly connected at one end with said ,link and terminating in the aforesaid block at its other end; another arm swingingly connected at one end with said link; another swinging arm with which vthe remaining'end of the last aforesaid arm is swingingly connected; and a supplemental feeding tool assembled with the last arm of the serie-s and maintained thereby in cooperative relation with the main feeding tool.
ln witness whereof, I hereunto subscribe my name this 26th day of April A. D., 1928.
