SEVJING-MACHINE.

Application filed November 14, 1911.

T all whom it may concern:

Be it known that I, DONALD NOBLE, a subject of the King of Great Britain, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented cer tain new and useful Improvements in Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements 1n blind stitch sewing machines and, broadly considered, is directed toward providing a more practical, durable and speedy construction.

In the development of machines of the class herein represented, various improvements have been devised to overcome the dif ficulties incident to adapting a single specific construction to meet the requirements of fabrics of varying thickness, texture and elasticity, which difliculties have, in a substantial degree, been due to a lack of means for maintaining a positive synchronization of the stitch-forming movements of the needle and coacting loop-taker with respect to the action of the fabric ridge-forming element.

In the present device, the movements of the needle-carrying bar directly control the relative action of the needle and loop-taker with respect to their loop-taking positions, and to this end the needle-carrying bar and looper-carrying shaft are mounted in an oscillatory carrier actuated from the main shaft of the sewing machine to form stitches first in one and then in the other of two, separate, horizontal planes, the mechanism for feeding the fabric being arranged and actuated so as to compensate for any in equality in the thickness of the fabric being operated upon.

Other advantages of the improved construction arise from a number of separate constructive features, each of which acts to more effectively control the functions of its coacting elements.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a plan view of a sewing machine embodying the invention. Fig. 2 is a right hand side elevation of Fig. 1. Fig. 3 is a left hand side elevation of Fig. 1. Fig. 4 is an underside view of Fig. 1. Fig. 5 is a front end elevation of Fig. 1. Fig. 6 is Specification of Letters Patent.

Fig. 14 is a diagrammatic view showing the character of the seam formed by the improved construction. Fig. 15, a central cross-section of the oppositely arranged, adjustably mounted, spring-controlled feed-actuating gears and their carrier.

1 represents the sewing machine frame in which is mounted in suitable bearings the main shaft 2 carrying at one end the beltpulley or hand-wheel 3 and at its opposite end the shaft-flange 4:.

5 represents an oscillating cylinder having formed integral with it a bearing stud 6 mounted in a suitable bearing 7 formed in said frame, said stud being held against endwise movement by nuts, as 8, threaded on the outer end of said stud.

Mounted to move endwise in suitable bearings formed in the cylinder 5 is a needleoarrying bar 9 provided at its forward end with a needle-bracket 10 in which is suitably secured an eye-pointed needle 11, and coacting with said needle is an oscillating threadcarrying loop-taker 12 provided with the usual bobbin 13, said loop-taker having formed integral with it a hollow loop-taker shaft 14 (see Fig. 6) mounted in a flanged bushing 15 secured in an opening. 16 formed in the cross-head 17 of the cylinder 5.

18 represents a screw bolt which passes through the base of the loop-taker and through the hollow loop-taker shaft and is threaded into a spirally threaded looperoscillating shaft 19, a suitable tongue and notch (not shown) acting to hold the shafts 14 and 19 in given relationship.

20 represents a screw stud threaded ina suitable bearing formed in the cross-wall 21 of the cylinder 5 and secured by nut 22, the forward end of said screw stud being provided with a flange 23 and bearing 24, the flange 23 acting against the inner end of the looper-oscillating shaft 19, and the bearing 24 entering a suitable opening formed in said looper-oscillating shaft.

Upon the pivot stud 25 threaded into the shaft-flange 4 is pivoted one end of the needle-bar-actuating connection comprising an externally threaded connection 26 and an internally threaded connection 27, the latter receiving the threaded end of the connection 26 and being provided with a bearing 28 in which is mounted a short shaft 29 having formed integral with it a pinch bearing 30 inwhich is secured, by a pinch screw 31, the needle-carrying bar 9. The opposite end of the shaft 29 has formed integral with it a collar '31 provided with a spirally-threaded opening 32 which coacts with the spirallythreaded looper-oscillating shaft 19 to oscillate the loop-taker to form stitches.

From the foregoing it is to be understood that the element 29 is provided with integrally-formed means for giving to the shaft 19 oscillatory movements, and that through the shaft-flange 4 and connections 26 and 27 horizontal movements are transmitted to the needle 11 which, as will be obvious, coacts with the loop-taker to form stitches.

As is well understood, in the formation of ablind stitch seam the needle passes alternately through and outside of the fabric and when piercing the fabric enters and emerges from the same side thereof, and this in the present instance is accomplished by giving to the cylinder 5 a rocking movement with respect to the plane of the fabric being stitched, as will now be explained.

Upon the main shaft 2 is secured a gear 33 which meshes with a gear 34 carried by a feed-actuating shaft 35, and as said gears are of the ratio of two to one, the shaft 35 is given one rotation to two rotations of the shaft 2. Secured to the forward end of the shaft 35 is a feed-disk 36 provided with an undercut groove 37 in which is secured, by a nut 38, a stud 39 upon which is pivoted one end of a depending link 40, the opposite end of which is pivotally connected with a feed-lever 41 fulcrumed upon a feed-shaft 42 and, by a screw 43, connected to an oscillating disk 44 forming a part of one form of commonly employed and well understood feed-actuating disk 45 secured upon the feed-shaft 42; and upon the end 46 of the shaft 35 is secured a flange 47 in which is secured a pin 48 with its axis eccentric to that of said shaft, and swiveled on said pin i,is3,572

is a block 49 which works in a groove 50 formed in an extended portion 51 of the oscillating cylinder 5, thus oscillatory move ments are transmitted to said cylinder through the elements 33, 34, 35, 48 and 49,

causing the stitch-forming mechanism to place stitches alternately in and outside of the fabric.

Upon the endof the shaft 42 opposite that carrying the feed-disk 45 is mounted a movable hollow shaft 52 secured to rotate with the shaft 42 by a key'53 and keyway 54, and upon said hollowshaft are rigidlysecured oppositely arranged bevel gears 55 and 56, there being mounted between the inner end wall of the shaft 52 and the end of the shaft 42 a coil spring 57 which acts to holdthe gear 56 in mesh with a gear 58 carried by an oscillating feed-shaft 59 upon the free. end of which are secured- serrated rotary feeddisks 60 and 61, thus, through the elements 42, 56, 58 and 59, step-by-step feed movements are transmitted from the disk 45to the feed- disks 60 and 61.

62 represents a rock-lever pivoted upon a shaft 63 mounted in the frame 1 and at its forward end provided'with a pin 64 which enters a suitable opening in the lower end of the fabric ridge-forming blade 65.

66 represents a horizontally arranged shaft mounted in suitable bearings .formed in the frame 1 and having secured to one end a rock-lever 67, one end of whiclrlatter is provided with a block 68 carried by the pin 48 which enters a slot 69 formed insaid lever, the rotation of said pin causingsaid lever to be rocked upon its fulcrum 66.

The opposite end of the lever 67 is divided and provided with oppositely arranged hearings in which is trunnionedashort shaft 70 through which passes a standard 71 secured at its lower end in a rock-shaft 71 carried by the rock-lever 62, said standard being threaded at its upper end to receive an.

adjusting nut 72 provided with a slightly tapered threaded portion 73 upon which is threaded a securing nut 74, the nut 72 being provided with a depending portion 75. Thus it will be seen that through the adjustment of the nut 72 vertical adjustment of the ridge-forming blade is effected when for any purpose it is desired to change the operative relationship of the upper end of said blade with respect to the line of needle actuation, a spring 72 seated at its lower end on the hub 73 of the standard 71 and having its upper end in contact with the inner end wall of the housing 74 threaded into the frame 1, normally acting to hold said ridge-forming blade in its elevated position.

lhe shafts 42 and 59 are mounted in suitable bearings formed in the transversely arranged sections 76 and 77 of the shaftbraeket 78, and upon the section 77 is securedyby a pinch screw 79, one end of a lever 80, the opposite end of which is pivotally attached to an upright rod 81 which passes through a housing 82 threaded into the frame 1 and is provided at its upper end with an adjusting nut 83 having an eX- tended threaded tapered portion 84 provided with a securing nut 85, and mounted upon the rod 81 is a spiral. spring 86 the upper end of which contacts with the inner wall of the housing 82 while its lower end is seated upon a collar 87 secured upon said rod, thus, through the action of said spring, the feed- disks 60 and 61 are resiliently held in their elevated or operative positions with respect to the fabric being acted upon.

To manually efiect the downward adjustment of the feed- disks 60 and 61 and blade 65, as when placing the fabric into or out of operative relationship with the stitchforming mechanism, there is provided a lever 88 secured to one end of a rock-shaft 89 mounted in suitable bearings formed in the frame 1, and upon said shaft is secured a bracket 90 provided with oppositely-arranged rollers 91 and 92, the former coacting with the lever 62 and the latter with the lever 80, to move the elements 60, 61 and 65 to their lower or inoperative positions, through a suitable foottreadle (not shown) connected with a treadle-rod 93.

When it is desired to reverse the direction of the feed of the fabric the operator, through a suitable manually-actuated treadle (not shown) connected with a treadle-wire 9-1, oscillates a bell crank lever 95 upon a short shaft 96 mounted in a bracket 97, thus causing the forked end 98 of said bell crank lever to move the hollow shaft 52 in a direction to disconnect the gear 56 from the gear 58 and place the gear in operative relationship with the gear 58, thus reversing the direction of rotation of the feed-disks and 61.

99 represents a take-up cam mounted on and to rotate with the main shaft 2, said cam being provided with a groove 100 in which tracks a follower 101 carried by a short arm 102 to which is attached a take-up lever 103, the arm 102 being pivoted upon the lower end of a stud 104 secured by nut 105 in the frame 1, and said follower being held in operative relationship with the groove 100 bv the head 106 of said stud.

The cloth-presser comprises an upright threaded portion 107, integrally-formed cross-bar 108 and swinging presser-foot 109, the latter being provided with upturned lugs, as 110, through which pass pivot screws, as 111, threaded into said cross-bar. The upright portion 107 passes through a vertical tubular portion 112 formed integral with a horizontal arm 113 slidably mounted in a tubular bearing 11 1 rigidly secured in an upwardly extended portion of the oscillating cylinder 5, a spring 115 acting to fabric. The horizontal arm 113 is free to oscillate in the tubular bearing 111 and to be moved endwise in opposition to the resiliency of the spring 116 mounted on the arm 113 and held confined between a shoulder 118 and the inner end of a nut 119 threaded upon the arm 113, thus permitting rocking movements of the cloth-presser 109 in the direction of and transverse to the line of the seam. The needle-thread is passed from the supply through a thread-check 120, threadtensions 121, thread-leader 122, takeup 123 and a suitable opening in the bracket 10 from where it is passed through the eye of the needle 11.

The operation of the machine is as follows :The operator, through a suitable treadle connection, first moves the lever 88 in the direction indicated by the arrow 6, thus placing the feed- disks 60 and 61 and ridge-forming blade in their depressed positions, and introduces the fabric to be operated upon above said feed-disks and below the cloth-presser 109, when the lever 88 and parts 60, 61 and 65 are permitted to take their normal positions with respect to the fabric, and the stitching is commenced. The ridge-forming blade is moved vertically in one direction during the formation of one stitch and in the opposite direction during the formation of the next subsequent stitch, its upward movement into contact with the fabric occurring just before the point of the needle enters the fabric to form the stitch 126, thus serving to firmly hold the fabric in the opening 12% of the presser-foot. When the needle has entered the fabric the blade 65 recedes so as not to influence the movement of the needle while advancing to present the loop to the action of the loop taker, and as the needle recedes from the fabric the resiliently held feed-disks and presser-foot follow the upward oscillation of the loop-taker and needle until the latter is clear of the fabric, and at such time the feed-disks are held against further upward movement by the nut 83 contacting with the housing 82, when the upward oscillation of the needle and loop-taker is continued to a position for forming the overseam stitch 125, and during the formation of said stitch the blade 65 occupies its depressed position, leaving the fabric free to be advanced under the needle but firmly held in contact with the feeddisks by the spring actuated presser-foot 109.

lVhen in the stitching operation a seam or other increased resistance is encountered, the feed- disks 60 and 61, as well as the ridgeforming blade 65, are caused to yield to the increased thickness.
