JOSEPH BERGER, J'B., 0F UTICA, NEW YORK, ASSIGNOR T0 UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CUBPORATION OF ILLINOIS.
SEWING-MACHINE.
Application filed January 8, 1913.
To all whom it may concern:
Be it known that I, Josnru BERGER, Jr., a citizen of the United States, residing at 10 Genesee street, Utica, in the county of Oneida, State of New York, have invented certain new and useful Improvements in SewingMachines, of which the following is a description, reference being had to the ac companying drawing and to the figures of reference marked thereon.
The invention relates to new and useful improvements in a sewing machine, and more particularly to a sewing machine having two or more needles which are set in a line cutting the line of feed diagonally, and
- in which a thread or cord is interlocked with the needle threads above the fabric for forming an edge covering or the like, as shown in the patent granted to Lansing Onderdonk December 3, 1912, #LMGAOI.
An object of the invention is to provide a machine of the above character with a plurality of thread carrying fingers coiiperating with the needles above the material, whereby a plurality of threads may be laid on the upper face of the material and a better covering for the fabric between the lines of stitching produced.
In the drawings which show by way of illustration one embodiment of the invention,Figure 1 is a front view of the forward end of the machine embodying my improvements, said parts being broken away to show the looper; Fig. 2 is a rear view of the machine; Fig. 3 is an end view thereof; Fig. d is an enlarged detail in perspective showing the arrangement of the thread carrying fingers relative to the needles, and the immediate mechanism for oscillating the same; Fig. 5 is a view partially in plan and partially in section showing the thread fingers, the mechanism for operating the same, and their relation to the needles; Fig. 6 is a diagrammatic View showing one position of the thread fingers relative to the needles; Fig. 7 is a similar view showing another position of the thread fingers relative to the needles. Fig. 8 is a view similar to Fig. 7 showing the fabric fed a stitch length and the threads laid on the face of the fabric stitched down.
In the drawings, I have shown a sewing machine which consists of a supporting bed Specification of Letters Patent.

Serial No. 740,894.
1, on which is mounted a standard 2, carrying an overhanging arm 3, at the forward end of which is a needle head 4. Also carried by the head plate 1 is a work support 5. Mounted to reciprocate in the needle head is a needle bar 6, which carries two needles 7 and 8. These needles 7 and 8, as clearly shown in Figs. 3 and 5, are arranged in the line which is diagonal to the line of feed. Cooperating with the needles 7 and 8 respectively are loopers 9 and 10, which are located beneath the work support, and operated in the usual manner. These loopers cooperate independently with the needles. It will be obvious, however, that any other form of stitch forming mechanism may be substituted for that herein shown.
Located beneath the work support is the usual feed dog 11, which cooperates with the presser foot 12 carried by the presser bar 13 mounted in the needle head at the forward end of the overhanging arm. This feed bar is connected with the feed rocker 14 which is moved back and forth by the usual mechanism and the feed dog is raised and lowered by an eccentric on the main shaft 15.
The presser foot 12 is formed with a diagonal slot 16 in which the needles 7 and 8 operate. Cooperating with the needles 7 and 8 are two thread fingers 17 and 18. The thread finger 18 is mounted directly in the lower end of the vertical shaft 19. This vertical shaft 19 is, in turn, mounted in suitable bearings in the needle head 4: at the forward end of the overhanging arm 3. The vertical shaft 19 is located at one side the line of shaft is also located in the rear of the needle bar, as shown in Figs. 3 and 5. The axis of this shaft 19 is preferably so disposed that the needles 7 and 8 are substantially equal distances therefrom. This permits the thread finger 18 carried by the shaft to move very close to the needles without striking the same. The shaft 19 is oscillated by an arm 20, which is secured at the upper end thereof and carries a ball stud on its outer end. A link 21 is connected to the arm 20. This link is preferably formed so that it may be lengthened or shortened for varying the position of the thread finger 18. The link 21 at its opposite endis connected to an arm 22 which is fixed to the shaft 23. The
As the main shaft 15 is rotated the shaft 23 will be oscillated, and will in turn oscillate the thread finger 18. These gears .26 and 27 are so proportioned that the shaft 23 will be oscillated once for every two complete rotations of the main shaft 15. As a result the thread finger 18 will move from one end of its stroke to the other end during one complete reciprocation of the needles, and will be moved in the opposite direction during a second complete reciprocation of the needles.
The thread finger 17 is fixedly connected to an arm 28 carried by a yoke 29 mounted to oscillate freely upon the shaft 19. This yoke between its ends carries a ball stud 30 to which is joined a link 31. The link 81 is connected at its opposite end to an arm 32 carried by the shaft 23 and extending downwardly from the shaft 23. As the shaft 23 is oscillated, it will, therefore, be apparent that the yoke 29 will be in turn oscillated and movements imparted to the thread finger 17. This link is formed with right and left hand threads at its ends, so that when the link is turned, the length thereof is varied in a well known manner in this art. The arm 22 extends upwardly from the shaft 23 while the arm 32 extends downwardly therefrom, as above noted. Therefore, these arms will move in opposite directions at their outer ends, and when the thread finger 18 moves in one direction, the thread finger 17 will be moved in the opposite direction.
The thread finger 17 is so positioned when at the forward end of its stroke that the covering thread a extends from the previous interlocking with the needle loop in rear of both of the needles 7 and 8. The thread finger 17'is so timed as to be retracted when the needles are in the material and rising therefrom. As a consequence, the thread a will be laid about both needles in the form of a loop, as shown in Fig. 7. When the thread finger 17 is at the forward end of its stroke, the thread finger 18 is at the rear end of its stroke, and the thread 7) carried thereby is laid entirely in rear of both needles 7 and 8. As the thread finger 17 moves to the rear end of its stroke, the thread finger 18 moves to the forward end of its stroke, and the thread 7) will be laid in loop form about both needles. Inasmuch as the needles make a complete reciprocation during the movement of each thread finger in one direction, the needles which arerising from the material will again enter the material before the thread fingers are again moved to the other end of their strokes, and during this time the feed of the fabric takes place so that the threads a and through the feed of the fabric are positioned in rear of the path of the needles 7 r and 8, and on the descent of the needles said needles will enter the fabric in front of the threads at and b, and the needle threads will be carried or laid over the threads a and b.
It will be apparent from the above description, that I have provided a sewing machine in which the needles are so positioned that independent loopers may 00- operate therewith beneath the work support, and the loopers be moved in a direction substantially at right angles to the line of feed. This positioning of the needles, as above noted, is in a line diagonal or oblique to the line of feed. I have also provided thread laying devices wherein a plurality of covering threads may be laid about the needles on the upper face of the fabric and said threads stitched to the fabric.
lVhile l have described the thread fingers as carrying a thread, it will be understood that l have used this term in the broad sense and that an ornamental cord may be used if desired.
It is obvious that minor changes in the details of construction and the arrangement of parts may be made without departing from the spirit of the invention, as set forth in the appended claims.
Having thus described my invention, what I claim is:
1. The combination of the stitch forming mechanism, including a plurality of needles set in an oblique position with respect to the line of feed, and a looper for each needle, of thread laying mechanism for laying threads on the upper face of the fabric, comprising thread carrying fingers, a vertical shaft supporting one of said fingers, means for operating the shaft, said vertical shaft being disposed at one side the line of feed, whereby the thread carrying finger moves in an are substantially equal distances from said needles, and means for supporting the other thread finger, whereby the same may be oscillated about the axis of said vertical shaft independently of said first named thread finger and in a direction opposed thereto, and means for oscillating said last named thread finger, the oscillating devices for the thread fingers being timed so that said thread fingers are moved simultaneously in opposite directions and are given one complete reciprocation for every two complete reciprocations of the needles. 7
