SerialNo. 144,209.
This invention relates to sewing machines and has for an object to provide a sewing machine having a novel form of frame which is particularly adapted for'stitching operations on hats. Further objects of the invention are to provide the machine with simple needle-bar operating and feeding' mechanisms. Further objects of the invention will appear from the following description and claims The frame comprises a hollow casting having a vertical standard from the top of which K Iextends a lateral bracket-arm having its free end curved downwardly; said armV having a smoothly curved and unobstructed upper surface and being devoid of upward projections, whereby the crown of a.y hat may, Without difficulty, be extend-ed over the endof such bracket-arm during a sewing operation. Joining the standard .adjacent the base of the Vlatter is a hollow work-supporting arm which is inclined at an angle to the standard and at its free endfcarries ahorizontal throat-plate directly under the free end of the bracketarm, whichbracket-arm carries a reciprocating needle-bar and spring-pressed presserbar.' Y f rlhe stitch-forming and feeding mechanisms within the frame preferably derive their movements from a short horizontal main-shaft which is journaled in the standard vin a plane parallel to the plane of the needle- Vbar and work-supporting arm.- lThis shaft may be geared to a vertical drive shaft within the standard, which shaft is connected at its upper end to the needle-bar operating mechanism and at its lower end to a loopershaft extending lengthwise of and within the inclined work-supporting arm; Lsuch loopershaft at its free end carrying a rotary chainstitch looper. The feeding mechanism in the .Specific embodiment herein disclosed comprises a novel form of feed-bar and actuating mechanism adapted to the present frame structure.
The feed-bar extends lengthwise f of and within the inclined work-supporting arm, below the looper-shaft, and upwardly within the standard to a point substantially level with the tl'iroat-plate where it is anchored to the frame by a universal or ball joint. Below the ball joint andl preferably .within the standard is a feed-bar guide which is entered by a downward extension of the feed-bar and confines the motion of the vertical portion of the feed-bar to the plane parallel to the vertical plane of the work-supporting arm. The inclined looper-shaft preferably carries within and near the free end of the work-supporting arm a feed-lift eccentric and an adjustable feed-advancing eccentric which may be connected through suitable mechanism to the feed-bar on the free end of which is mounted a feed-dog extending upwardly through the throat-plate.
In the accompanying drawings Fig. l is a rear side elevation of a sewing machine embodying the invention. Fig. 2 is a front end elevation. Figs. 3 and 4 are, respectively, enlarged sections on the lines 3-3 and L -1, Fig. 1. Fig. 5 shows the portion of the looper-shaft which carries the feed-eccentrica Fig. 6 shows the portion of the feed-bar to which the 'feeding connections are made. Fig. 7 is a section on the line 7 7, Fig. 1; and Fig. 8 is a plan view, partly diagrammatic, of thefceding mechanism. y
In the preferred embodiment of the invention illustrated, the frame casting comprises a hollow vertical standard l having a base 2. Extending laterally from the upper end of the standard l is the hollow bracket-arm 3 which is curved downwardly at its free end 4 which carrie-s the reciprocating needle-bar 5 and presser-bar 6. The bracket-arm 3 has a smooth and unobstructed surface, devoid of upward projections, so that the crown of a hat A (in full lines) Fig. l, may be readily thrown over the free end of the bracket-arm during a stitching operation.
Extendi n g at an angle to the standard l and lio joining the standard adjacent the base 2 is the hollow inclined work-supporting arm 7 carrying at its free end the horizontal throator cloth-plate 8 and removable end cap 9. The inclined arm 7 facilitates many stitching o operations on hats and avoids the necessity of k standard 1, is the vertical drive shaft 13 to the vupper end of which is secured the balanced crank 14. The shaft 13 extends through the lubricant cavity 15, cast within the standard 1, and has fixed thereto within such cavity a bevel gear 1G with which meshes a bevel gear 17 carried by t-he inner end of the horizontal main-shaft 13 ournaled in the standard 1 iny parallelism with the plane of the needle-bar and work-supporting arm 7. The cavity is closed by an inner cover-plate 15. The main-shaft 18 carries a suitable beltpulley and balance-wheel 19. The lubricant cavity 15 may be packed with a suitable gear lubricant which is closely confined with the gears 16, 17.
The needle-bar 5 carrying the eye-pointed needle 20 is connected by the link 21 to the forwardly extending arm 22 of a bellcrank- Alever fulcrumed at 23 in the downwardly curved end 4 of the bracket-arm 3. The upstandingarm 24 of the bellcrank-lever is connected by a ball-and-socket joint to the pit- -man 25 which extends lengthwise of and within the bracket-arm 3 and has a ball-and-socket connection with the crank 14. This needlebar operating mechanism is simple and particularly well adapted for use l'within a hollow bracket-arm having a downwardly curved free end and no obstructions on its upper smoothly curved surface.
The presser-bar 6 carries a presser-foot 26 which is pressed upon the work by the leaf spring 27 housed within the hollow arm 3. The spring 27 is anchoredV at one end to the pin 28 and at its free end rests upon the top end 29 of the presser-bar. The thumb-screw 30 bearing upon the spring 27 is used to adjust the pressure thereof upon the presserbar. The usual cam-lever 31 is used to lift the presser-foot. lt acts upon the lateral pin 32 fixed to the presser-bar. A needle-thread take-up 33 is carried by the needle-bar 5.
dournaled within and longitudinally of the inclined work-supporting arm 7 is the looper-sliaft 34 which is geared at 35 to the vertical shaft 13 and at its upper end carries a rotary chain-stitch looper 36.
The feeding mechanism comprises a fourmotion feed-bar of angular form including a vertical portion 37 within the standard 1 and an inclined portion 38 within the work-supporting arm 7, joined rigidly together by means of the connecting arm 39. The Vportion 37 of the feed-bar is hung from the ballstud anchorage 40 within the standard 1 and at its lower end enters the guide-slot 41 adadjacent the base 2. Secured to the free end of the inclined portion 38 of the feed-bar is the carrier 42 for the feed-dog 43. It will be observed that the ball and socket joint 40 constitutes a fixed universal-joiiit connection between one end of the feed-bar and the sewing machine frame within the standard, such universal-joint connection being fixed in the sense that it has no bodily movement as a Ywhole relative vto the sewing Ymachine frame.
Also, it will be observed that the universaljoint connection 40 is about on a level with the cloth-plate 8 so that the swinging movement of the feed-bar about such connection will give to the feed-dog substantially vertical rising and falling movements, such movements being derived from the ballcrank or. eccentric 44 which is connected by the link 45 to the ball 46 on the feed-bar member 33.
eed-and-return movements are imparted to the feed-bar by means of the adjustable eccentric 47 carried by the looper-shaft 34. The eccentric 47 is embraced by the forked arm 48 of a bellcrank-lever oiirnaled on theV stationary'stud-pin 49 and including a downwardly extending arm 50 which is connected by the link 51 to the ball 52 on the feed-bar member 38. Mounted on the feed-dog carrier 42 is a Vroller-stud 53 which Yenters a guide-slot 54 in a member fixed to the arm 7. The guide-slot 54 is very slightly curved in a horizontal plane about the 'ball-stud '40 as a center, and the roller 53 is slightly barrelshaped so as not to cramp in the guide-slot during the rising-and-falling movements of the feed-dog. The present feeding mechanism is particularly well adapt-ed for incorporation in a work-supporting arm, and particularly in an inclined work-supporting arm, for feeding across the arm.
