NEEDLE-FEED CHAIN-STITCH SEWING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 691,311, dated January 14, 1902.
Application filed July 13,1901. Serial No. 68,218. (No model.)
following is a specification.
My present invention is designed as an im provement on the machine covered by the Letters Patent granted to me on the 2d day of July, 1901, No. 677,740; and the object of my present invention is, first, to simplify the construction of the presser-foot; second, to simplify the construction of the guide or fulcrum plate, and, third, to provide a better spring for the Presser-foot. I attain these objects by the mechanism illustrated inthe accompanying drawings, in which- Figure 1 is a side elevation of a sewingmachine constructed according to my present invention, a part being broken away. Fig. 2 is a top plan view thereof, and Fig. 3 is a front view of apart of the machine on alarger scale.
In the accompanying drawings like parts are indicated by the same numerals of reference in each of the views, and in the practice ofmy invention I provide the presserfoot 5 with a perpendicular standard 6, integral with the cross-piece 7, which is pivoted to the frame at 8, and a handle 9 is provided to operate said cross-piece and presser-foot. On the opposite side of the machine an angular extension 10 of the cross-piece 7 is provided, between which and the frame is mounted a compression-spring 11, working on a pin 12 in said extension, and the other end is seated in a socket 13, formed in the side of the frame, as clearly shown in Fig. 3. By reason of this construction itis not necessary to mount a pin or place a stud on the side of the frame to hold the spring in position, and more space is created for the spring, so that a longer and better spring can be used, and the extension will not be prevented coming close to the frame when the presser-foot is raised.
The guide or fulcrum plate 14 is provided with a central longitudinaljslot 15, through 7 of the presser-foot, and the metal removed to form said slot is left attached at the lower end thereof and is bent outward at right angles to the plate 14, as shown at 18, and is provided with an eye 19, through which the needle 20 passes, the upper end of the needle being mounted on the crank 21, and the throw of the needle is adjusted by moving the plate 14; up and down on the screw 16, as will be readily understood. The plate 14; is provided with wings 22, which engage the standard 6 of the presser-foot, which acts as a guide for the lower end of said plate. By this construction I get a very cheap and efficient fulcrumplate, and the adjustment of the same is always in a vertical plane.
By the construction of presser-foot the crosspicce is considerably above the presser-foot, which is curved upward at both ends and makes a very neat and efficient foot.
In this class of machines the shaft 23 is rotated, which causes the point of the needle 20 to describe an ellipse and feeds the cloth forward underneath the presser foot. A hook-needle is used, and the thread is fed to th'eneedle by the spring 24 in a manner described in my other patent. As this spring projects across the path of the needle, the needle would be caught andbroken if the shaft were to be rotated backward. To prevent this, I have provided a ratchet-wheel which a screw 16 is passed into the cross-piece 25, which is mounted on the shaft 23, and I at 27 to the frame and engages the ratchetwheel 25, thereby preventing the rotation of th'eshaft 23 in the wrong direction. By using a gravity-pawl constructed in this manner scarcely any noise is made, which is not the case if a spring-pawl is used, and the pawl can be thrown out of engagement when required.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A needle-feed for a chain-stitch sewingmachine, the same comprising a needle, a presser foot pivoted to the frame of the machine and provided with a vertical standard,
and a plate carried by said presser-foot and serving as a fulcrum for said needle, and provided 'With wings engaging said standard, as and for the purpose set forth.
2. The combination with a chain-stitch sewing-machine of a presser-foot pivoted to the frame of the machine and having an angular extension, the frame of the machine being provided with a socket back of said extension, and a compression-spring mounted in said socket, and engaging said extension, as and for the purpose set forth.
' In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
