Application filed March 1, 1916. Serial No. 81,808.

To all whom it may concern:

Be it known that I, JOHN P. WEIS, a citizen of the United States, residing at N yack, in the county of Rockland and State of New York, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification.

This invention relates to sewing machines and particularly to that class of cylinder sewing machines adapted forstitching tubular goods, an object of the invention being to provide a machine for making separate rows of ornamental stitches, one row being spaced from the other to suit the'requirements, and which ornamental stitches will comprise a cover stitch on the bottom of the work as well as on the top thereof, together foot and feeding mechanisms to carry the work past the stitching mechanism.

The object of the present improvement is the provision of a machine for stitchin a knit strip of cloth to the shoulder of un ergarments, such strip being cut with the Wale of the fabric, but which when stitched to the garment will have its wales at right angles to the wales of the knit garment itself so as to overcome the sagging or stretching of the shoulders thereof. A large proportion of the better grade of knit underwear is made in this fashion, but this is accomplished by having the shoulder strips previously cut to a width and length to conform to the size of the garment. Then one edge thereof is stitched to one side of the shoulder'portion of the garment by an ornamental stitch ma-- chine, and then the opposite edge is subsequently stitched to the other shoulder portion of the garment and in this manner.

the shoulder seams are finished. With the present improvement, however, the-strip of cloth is cut in long continuous lengths and when properly rolled is suitably mounted on top of the sewing machine and guided to the stitching mechanism,- shown herein as a automatically and both seams stitched simultaneously, the throat plate being provided with suitable edges of the shoulder portions of-the garment so that the operation is much simpler and quicker to perform and the finished work is uniform.

. raising and lowering .useful in machines of the The invention is also useful in the manufacture of that class of undergarments made from woven fabric, such as B. V. D.s for instance, some of which are provided with a strip .of knit goods down each leg of the garment and sometimes around the waist thereof to give elasticity to a portion of the garment, as for instance, the back of the body portion and the knee of the leg portion. At present these operations are done in the same manner described in connection with the shoulder seam and, therefore, it will be apparent that a substantial the use of my improvement in the manufacture of such garments and that articles are more salable.

Among the objects of the-invention is also the provision of an improved form of looper mechanism and an improved form of thread carrying finger mechanism. and means for the latter simultaneouslywith the presser foot by means of which the foregoing work may be performed.

A further object of the invention is the provision of an improved thread carrying or cross stitch finger mechanism, particularly character described, but which may be also advantageously used in other kinds of sewing machines if desired.

1 A still further object of the invention is he anism,

the finished also particularly useful in connection with the present improved machine,

but which likewise may be advantageously used with other forms of sewing machines.

In the drawings accompanying and forming a part of this specification, Figure 1 is a longitudinal sectionalview of the machine, showing the working parts and particularly the looper mechanism and the top cross stitch andneedle operating mechanisms Fig. 2 is a cross sectional view of the, shoulder seam; Fig. 3 is a top view of the shoulder portion of a garment, looking directly at it from the arm-hole side; Fig. 4 is a detail'view of the presser foot; Fig. 5 is a top view of the throat plate; Fig. 6 is an end view of the throat plate; Fig. 7 is an 3 end view of the machine showing portions is deemed unnecessary herein.

"Fig. 8 is a detail of the thread pull-off demechanism with. the end cover thereof In section, and Fig. 12 is an enlarged View illustrating one of the rows of stitches, one of the finger thread stitches being shown slightly wider or of rope form so as to differentiate it from its companion finger thread stitch.

Similar character corresponding parts in the drawings.

As the invention is useful in connection with any cylinder machine, and particularly that shown in my application filed December 2, 1915, Serial No. 64,630, now Patent No. 1,221,254, dated April 3, 1917, a detailed description of the main part of the machine of reference indicate the several figures of The machine base 1 has its cylindrical bed or horn 2 thereof carrying a looper shaft. 3 and a feeding mechanism actuated by the connections 5, while the feed is operated by the connections 6, all driven by the top rotary shaft 7. The top part of the machine frame comprises a vertical trunk 8 and an overhanging arm 9 provided with bearings 10, 11 and 12. The bearing '10 carries a bushing 13, and a belt or hand wheel 14 is secured to the top shaftadj acent to this bushing 13, while a tubular incasement 15 supports the forward end of this top shaft 7. The machine head 16, carrying the needle driving mechanism may be a separate part from the overhanging arm 9 and clamped on to the incasement 15 in any suitable manner. as at 17, so that various stitching devices can be readily applied by substituting one head for another with the proper mechanism carried thereby. In the present instance the head 16 carries'a gear 18 and a crank disk 19 driven by the top shaft 7. This disk has a crank pin 20 op- 21 connected as at 22 to a cross bar 23 secured to the needle bars 24. The needle bars 24 carry needle chucks 25 and needles 26 spaced to suit the character of work. Each needle bar operates in a sleeve 27, see Fig. 7, provided with a gear This sleeve 27 in turn operates in a similar sleeve 29 also carrying a gear 30. A collar 31 is clamped to the bottom of the outer sleeve 29, and has secured thereto a 32. The inner sleeve 27 also has a collar 33 carrying a thread carrying finger 34. The gears 28 of the two sleeves 27 co-act with a segmental gear 35 while the gears of the two sleeves 29 coact with a segmental gear 36. The gear 36 is in the rear of the gears 30 while-the gear is in the front of the gears 28 so as-to give 4. The looper'is nism, as at 45.

reverse motion to the thread carrying fintal gears 35 and 36 are carried by a swin ing arm 37 pivotally hung, as at 38, in the top of the machine head 16 for oscillating motion, and this arm is so shaped as to clear the other moving parts and is provided with a slot 39 in which moves a slide block 40. This block 40 is operated by a crank pin 41 carried by a large gear 42 in mesh with a smaller gear 18, forming a two to one reduction to cause the thread carrying fingers to cross the threads underneath the needles at every other stitch. In order that the thread carrying fingers may operate close to the work it is necessary to have them controlled automatically to and from the work with respect to the thickness thereof. To accomplish this the segmental gear 35 is provided with a rabbeted portion 43, overhanging the gears 28 to keep them tion, and to lift the fingers I have provided a lift-er 44 to co-act with the collars 31 and a post 44 carried by the presser foot mecha- This post has a roller 46 co-acting with the bottom portion of the segmental gear 36 to lift it.

The presser foot mechanism consists of a presser foot shank 47 having presser feet 48 hinged thereto by pins 49, see Fig. 4, and provided with guiding lips 50 to guide the shoulder strip 51 of knit cloth. These presser feet have openings 52 and tongues 53 over which the stitches are formed. It will of course be obvious that if for certain classes of work it should be desired in practice to make the presser foot in one piece instead of two, that is to say as a single bottom instead of independent bottoms as shown, such mere mechanical change does not in any way affect the invention. These presser feet are carried by the presser bar 54secured to the presser lifter bracket 55.

A guide fin 56 is also carried by the bracket and operates in a slot of the head 16 to steady the movement thereof. This bracket is curved as at 58 to fit underneath the arm 9 so as to occupy as little space as possible, be ri id in construction and not interfere with the work, and it is pivotally secured as at 59 to the trunk of the machine at each side thereof and has an extending arm 60 which may be operated by a chain 61 conin working relathese thread guides 68 are mounted on posts 69 for vertical adjustment toproperly control the finger threads.

From the foregoing it will be seen that tWo independent needle carriers are provided as well as two independent cross stitch devices cooperating therewith, a single driving mechanism for the needles and a single driving mechanism for the cross stitch fingers, and that the action or movement of the thread carrying fingers is confined close to and around the needles so as not to interfere with the handling of the work or the fingers of the operator in the manipulation ereof. In other words the present improved machine is provided with two sets or pairs of spaced or separated needles and not only does a looper cooperate with each of thread carrying fingers cooperating with of needles, and each thread around the axis of the needle holders. 7

Attached to the cylindrical bed 2 is an end bracket 70 secured to the cylinder by screws 71. his bracket is tapered toward the rear to enable the Work to be removed quickly and is also in the form of an attachment so that different gages of loopers may be used to suit the-needle spacings. e looper driving meshing with segcarried on short looper shafts and 81 each having a looper socket hub 76, see Fig. 9, to carry a looper or 83 and these hubs are cut out as at movement. The short looper shafts are slidingly supported in the bracket 70 in lelism with the looper driving shaft 3. Each gear 74 and is provided with guide plates 84 to fit close .to the the regular four-motion movement is transthe loopers so that they operate on the back of the needles in taking the needle loops andon the. front of the attached directly to the haft 3. n t e present improvement the oopers, although driven by the same driving means, are separately mounted, that is to lave if it were has a movement which, as h para-lti l.

carried by the same say, both loopers are not One of the advantages of this conshaft.

struction is that the loopers can be so sup- Fig. 10; I

The organization shown for operating the loopers is merely one way by which the doule looper movement may be accomplished from the main looper shaft so that the loopers may bespaced one from the other, andI do not desire to be limited to the construe tion shown.

the work done by the machine 18 illustrated. The shoulder strip is 51 while the bottom portion of the garment is 93, 94'is the arm hole, 95 the seams joining the shoulder strip to garment and 96 represents the top cross stitches and 97 represents the bottom stitches.

In Fig. 12 is shown one of the rows of stitches in which'96 illustrates one of the finger threads while 96 illustrates the other of the finger threads while the needle stitches are indicated by 97' and 97 and it will be observed that each of the stitches is opportunity for the raveling zwoided as would be th each alternative finger thread down by a needle thread.
