Application led November 25, 1914. Serial'No. 8f3/,872.
To all who/a t may concern:
Be it known that I, ALBERT H. DE Von, a citizen of the United States, residing at VeStield, in the county of Union and State of New Jersey, have invented certain new and useful vImprovements iii @Sewing-Machines, of which the following is a speciication, reference being-had therein to the acconipanying` drawings.
This invention relates tov an improvement in that class of sewing machines designed for sewing tubular articles, suclr a's the sleeves of garments, in such manner that the article is delivered from the work-supporting member of the machine by the action'of the feedingr mechanism as the stitchingl proceeds. The improvement has for one of its chief objects the construction of the machine` frame in such manner as to facilitate the handling of the Workand its Vdelivery to the stitch-forming mechanism under advantageous conditions. l,It has for another object' to provide a simple and effective mechanism for operation upon the work. i
The machine-frame is preferably constructed in general conformity with that shown and described in my pending application Serial No. 852,345, tiled July 1914, with the work-supporting member disposedI transversely to and laterally ,offset from the standard with which it is connected by Y, means spaced above the base of the standard'.
That portion of the wOrk-supporting .nem-
ber nearest its connection with the standard is preferably contracted iii girth, and may be made both of `less width and less depth than the opposite end portion provided with the feeding and stitchingineaiis, inorder to alloi7 ample slack in the material to be presented to the stitch-forming mechanism and. to accommodate the. operators fingers in manipulating it on its way to the stitching mechanism. i y A The .-uncontracted portion of the' Worksuppoiting member is preferably formed with reciprocally and laterally swinging sec-A tions each sustaining a loop-taker perma-` ently connected by suitable gearing With a driving gear upon a shaft mounted in fixed bearings of the Work-supporting member.
and itself connected through a suitable train of gearing, including an intermediate shaft, With the main-shaft journaled within a laterally extending frame-member connecting the upper portion of the standard of the Work-supporting dependent connections with the said sleeve by .meaiis of which the needle-bar actuating eccentric is caused to impart operative workadvancing and rising-and-falling movements to the feed-dog. 'The needle-actuating eccentric preferably carries a crank-pin in its outer face fitted-Within a'n aperture of a socket member embracing theshank of a needle-thread take-up arm mounted upon a fixed fulcrum adjacent the junction of the intermediate frame-member and the Work-l supporting member.
Journaled within aiidlongitudinally of `theinterinediate frame-meinber is a rockshaft from which is laterally extended, preferably in a direction inclined to the length of the Work-supporting member, a rigid arm carrying the presser-foot. VAsthe vibratory needle-carrying arm is disposed above and' dog, the rock-lever and slide-bar having inlengthwise ofthe ivxi'rk-supporting member,`
it is desirable that the operators vision be further obstructedvas little as possible by other yelements of` the mechanism, and by' extending `the vpressii'-f oot supporting arm at aflateral. inclination with the Work-supporting member and theneedle-carrying i arm, thisy element is brought to one side of the operators range. of view of the Work which is downwardly inclined over the end member connected i'vith the intermediate frame-member. f In the accompanying drawings, Figure-l is a front elevation, With the frame in section, and Fig. 2 a side elevation, ofa machine constructed with the present improvements. i Fig; 3 is a rear elevation of the machine,
with the rearward portion of the Work-supporting member partly in section, and I iig. 4 a sectional plan vieiir of the frame standard With the .presser-foot lifting means. Fig. 5 is a plan of the machine. Fig. 6 is a Sectional elevation of the. Work-supporting member and the parts carried thereby,Fig. 7 a plan of the lwork-supporting member, partly in section, with certain parts ,carried thereby, and Fig. 7 a detail sectionalview of an element of the loop-taker adjusting ,means FigI 8 is 'a side view of the needle and feedlmeclranisms. I
As represented in the drawings, the frame comprises the hollow upright standard 1 having the flangedv base 2 and sustaining at its upper end the lateral armcomprising the tubular Imember 3 tern'iinating in the downwardly inclined` extensionl 3 connected with the top of 'the horizontal work-supporting member 4` depending therefrom.V At the junction of the extension'y with the member v 4 is a cavity 3 for housing certain of'the operative-parts, this cavity being partially closed by 'means fof the end-cap 5. The otherwise oval body portion of the standard is shown (see particularly, Figs. 1 and 4) Vflattened at 1" on the front `and inner side n the intermediate iframe member by means of a contracted portion et', the outer uncontracie'd portion being cut away laterallyat the upper side. to 'form at the lower side the supportingwton ue it, above which are pivotally mounle by 'means of the vertical studn pins 6 the laterally swinging sections 7 As shown in the drawings, ,the contracted.
portion of the "work-supporting member is both narrower and of less -depth than the uncontracted4 portion -within which thecoperate in. the.
stitch-forming elements A production of the stitching. The uncontracted portionl of the worksupporting arm is made et sufficient width and depth to accommodatethe loop-takers and. the `feed-dog with their accessories, but is'made :1s small as practicable to accommo- -date the smal.lest-tubular 'portions of gar-` ments to be stitched. The inner contracted portion of the work-supportingmember,l ar
ranged between the un'contmcted ortion and the intermediate frame-member, 1s made suliiclently smaller than the adjacent portion to permit ample clearance for the4 finger-sof the operator in manipulating the fabric around the same preparatory toits presentation to the stitch-forming mecha#v 1|isin. By this means, the operator is enabled to handle the work with ease and is not cramped by necessity of formingA the ,garment for stitching from the outer ,face .of the fabric, which would be the case if the forward portion of j the Worlgfsupporting member were uncontractedt nemers The throat-plate 8 is secured upon the top ot the post e at one end by means of the screw 9 and upon the upper face f the member 4 at the opposite end by means. of vthe screws 10. rihe throat-plate is provided with the usual feed-dogopening 11 and `noodle-apertures adjacent ythe same.
111g operative movements to the needles and.
the feeding mechanism. Adjacent the eccentric 15 the main-shaft has ixedthereon `a bevel pinion 16 meshing with asimilar pinion 17 upon the short intermediate shaft 18 which is in turn connected means ofthe intermeshing bevel pinions '19 and .2G with the loop-taker lactuating 'shaft 21 journaied within and longitudinally of the work-supportingarm and having i'ixed upon its outer extremity the driving wear 22.
lInterineshing with't e driving gear 22 are the pinions 23each 'fixed upon a short shaft 24 journaled in'bcaring bushings 25 of the respective laterally swinging sections 7: The stud-pinsA 6 upon which the sections 'Z are fulcrumed have their axes preferably inintersecting relation with the pitch line oi'4 Athe driving gear with the respective pinions 23 and at the rear face of the latter, so that in the swinging of suchsections between operative and retracted positions the pinions vwill be Amaintained permanently in mesh with the Fig. 7. ljlachshaft 24 has fixed thereon a spiral gear` 2 meshing with a similargear 27 which is shown formed upon the hub of the cup-shaped loop-taker 23. The loop-taker hub is mounted upon the'lixed horizontal ulcrum stud-screw 29 tapped into the, adjustably`r sustainedholding plate 30. The
driving. gear, asv represented in late 30 is formed on its inner :tace with an vintegral stud 31 and it carries a. second stud 32- parallel therewith having near its outer end a flange 33 beyond which is an eccentric necked pportionli closely embraced by the vside edges of a slot extending lengthwise of j lthe plate 30, the stud 32 being held in position by means of the'clamp-screw 35 between' whose head and the flange 34 the surroundfy ing portion ofthe plate 3()l is clamped.
The studs 31 and 32 are` slidin l t y lit-ted within suitable apertures in thebo y y offthe 4section 7- within lwhich they are 'secured by set-screws 36 in the desired position oi'. end,
wise adjustment of thev gear tor the po sired gage of the seams. By looseningl the set-screws 36 and turning the stud 32 through the clamp-screw 35, the stud 32 may be shifted transversely ot' its length, thereby raising or lowering th, corresponding end of the holding plate 30 and correspondingly adjusting the position of the loop-taker and its connected spiral gear for taking up wear or for other purposes.
The loop-takers represented in the drawings are of a well-known type, being formed with a loop-taking beak in the outer end' and having fitted within the same a threadcase 37 provided with a bobbin 38. As shown and described more fully in my pend# ing application Serial No. 852, 345, each of the sections 7 is provided with a holding plate or" hanger 39 pivoted thereto aty the lower end and provided with a lateral arm 40 adapted for engagement with the hooked end 4l of a spring 42. secured in a longitudlnal channel of the pin 48 mounted within a suitable transverse aperture of the section 7 in which it is adjustably secured by means of the set-screw 44 (Fig.
The pin has a transverse aperture entered by the reduced extremity of the plunger-pin 45 fitted within a suitable aperf ture of the section 7A and resting upon the spring 42. The section 7 having been retracted as -represented in the lower part of Fig. 7, by depressing the plunger-pin 45 the spring 4Q is defiected to disengage it from the hanger 39 which may be swung outwardly for access to the thread-cavity of the loop-taker.
Each' of the sections 7 is provided witha spring-catch 46 whose hooked operative eX- tremity 47 is adapted for engagement .with
the shoulder of one of the latchfplates 48 secured by means of screws 49 adjustably in i position upon the post 4". '".nese sections are normally held in operative position by engagement of the spring-catches with their respect-ive catch-plates, and may be vretracted for introduction and removal of the lower thread supplyto the loop-takers byy pressing inwardlyv the spring-catches for their disengagement from the shouldered catchplates. i
Secured upon the inner 'face of the lend? cap'5 by means of the screw 50 is a fulerumstud 5l disposed vabove the work-supporting member and near its junction with the intermediate trame-member. Momted upon the stud 51`and maintained in position there.- o'n by the cap-screw 52 is the hub of the needle-carrying arm 54 provided in its outer end portion with a. socket in which is secured by means of the set-screw 55 the shank 56 of the needle-clamp 57 which .carries in practice two eye-pointed needles 58 coperating with the loop-takers 28 in the production of stitches. l
The hub 53 isw formed with the rearwardly y extending boss 59 sustaining the pin 60 which is slidingly fitt^d within a tangential socket or aperture of the boss 61 formed upon the lower side of the sleeve 62 which is in turn fitted upon the actuating eccentric l5 ofthe main-shaft. The needle-arm 54 derives, from the described pin-andsocket connection with the sleeve 62 embracing the actuatin-g eccentric, vibratory movements from which the needles 58 derive their sub-y stantially rectilinear reciprocations.
The hub of the needle-arm 54 has upon one side of said arm a rearward extension 63 to which is pivotally connected one end of a link 64 whose opposite end is sin'iilarly connected with the rearwardly extending arm of'a rock-lever 65 mounted upon the fixed transverse fulcrum-pin 66 and formed with a longitudinally extending tubular member 67 disposed above the fulcrum-pin- Slidingly fitted within the member 67 is the tubular bar 68 constituting the shank of the feed-dog 69.
Secured by means of a set-screw 70 within l a socket in the forward end of the slide-bar 68' is one end of a flexible rod 7l whose opposite end is secured Within the rocking stud-pin 72 upon the adjustable blockl 73 fitted within 'a lateral recess of the feed rocklever 74. y The lever 74 ismounted upon the fulcrum-stud 75 tapped into theVcap-plate and secured in position by the jam-nut 75. The block 73 is secured for adjustment toward vtnd from the fulcrum 75 by means of the screw v'(6 passing through an elongated slot of the lever 74 and tapped into said block 73 which may be adjusted by loosening the screw 76 and shifting the block and retightening said screw. The upper arm of the lever 7 4 isformed as a slide-pin 77 which,Y is fitted within a lateral tubular boss or socket 78 or" a collar 79 `embracing the shouldered crank-pin 80 which is secured in the split boss 8l of the sleeve 62.
From its described connections, the teendog receives its to-and-fro or work-advancing movementsfrom thesleeve 62 em' bracing the common actuating eccentric l5; while tilting movements are imparted to the rock-lever 65,'and hence rising-and-alling' movements of the needles and both Vthe worladvancing and the rising-and-falling movements of the feed-dog are derived from the common actuating element upon the shaft l2.
Tapped into the cap-plate 5 in which itis secured by the jam-nut 82 is the fulcrumstud 83 upon which is mounted the sleeve 84- ,r
having a split socket 8e in which is clamped l t means oi the bushing sleeve 105.
by means oi the screw vthe take-up arm 86 having the reduced and backwardly bent portion 87 provided with the usual threado eye. Slidinglyitted upon the straight cylindrical portion of the arm 86 is a sleeve 88 formed `with a lateral lug 89 apertured to receive the crank-stud 90 which is tapped into the outer face oi the actnatingeccento tric 15.
l In the. rotation of the eccentric 15 with the shaft, the crank-stud l90 is carried in a circular path and thereby communicates to the takeup arm through the described .lo connections vibratory movements upon the fulcrum-stud 83, klt will thus be seen that the reciprocation of the needles, the operative movements of the eed-dogA and the f vibratory movements oi' the take-up arm are 2o all derived from operative connections with theA actuating element 15 upon the main' shafte and that the timing, of these several members is therefore fixed for all adjust- .dunder all operative conditions of to the mattine..
pposed to the feed-dog is'the usual presser-toot composed in the present instance of the preureplate 91 pivotally l connected with the lower end yof theshank 92 Whose so upper end is fitted Within the transverse boss 9S of the laterally extending arm 9i lia-ving a hub 95 secured by means ofthe setserew A96 upon the rock-shaft 9? which is journaled Within and longitudinally of,
es the intermediate :frame member 8 parallel withl the main-shaft The presser-foot carrying' arm 94 extends from a position intermediate the ends of the :framefmember 3 in a direction inclined to the Worlosnpeo porting member e, i', as represented particularly in Fig. 5, in order to avoid obstructing the View or the operator in look;
toward the stitching position. et The roclrfshaft -9?' has secured upon its /rearward end .a collar 98 from which extends upwardly the laterally offset -tappet-aiin 99,
and from which depends a second arm 100;
The forwardY face ci? the tappet-arm 99 is to engaged. by one 'end oli a pin `101 Whose 104 acts through the pins .102 and 4101 upon the tappet--ar1n 99 and thence thronghthe rocleshaft and lateral arm 94 to thrust the pressenfoot downward upon the work-sup- @t port, and the stress of the spring lis adapted ing across the extremityA of the member 3 zo. neonato to be regulated in a manner Well-lrnovvn by The standard. 1 is provided near its bese with the n spaced and apertured lugs lilo to receive the ulcrum-pin 107 upon. which is mounted the hub 108 oi a rock-lever 'trav-- y ing one arm 109 extending inwardly throngi the wallet the standard Where. it is provided with a roller-stud 110 adapted tor engagement With one edgeo the depending' rock-shaft arm 100, as represented in Fig. e. An oppositely extending arm lll of said rock-lever is formed with an eye to receive the hooked extremity 112 of the treadle rod 113 by means of which the rock-lever 103 109 111 may be operated to press the arm 100 laterally and thereby rock the shait 97 in opposition to the spring 10d to liftw the presser-foot. ,In preparing the machine for operation, the two needlethreads are led 'from the source egt supply through. the apertured lugs 111i` of the tension-supporting' plate l115 and thence between the tension disks 116 from which they are led through 'apertures 117 in a forward extension ofthe plate 115, over the guide-finger 118 and thence through the eyev of the take-np arm 86 87 from which they are led through a guide-aperture 119 in the enter end o? the needle-carrying arm 54 to `the needl ln presenting the Work ir action :be
