Description

April 16, 1935. A. STROBEL BLIND STITCH SEWING MACHINE Filed Sept. 20, 1930 M M m ALFo/vs STROBE L.
Arron/v1: x
Patented Apr. 16, 1935 UNITED STATES PATENT OFFICE Application September 20, 1930, Serial No. 483,315 In'Germany September 24, 1929 2 Claims.
The invention relates to blind stitch sewing machines in which the work is supported under the stitch plate by a saddle and is pressed against the sides of the saddle by benders.
The object of the invention is to enable machines of this kind to be easily adjusted for sewing cloths of dlfierent thicknesses.
For this purpose the benders are, according to the invention, carried by levers abutting against springs having adjustable holders, so that the position of the benders in relation to the saddle can be adjusted by adjusting the spring holders.
An embodiment of the invention is shown in the accompanying drawing, in which Fig. 1 is an elevation of the relevant parts of 15 a sewing machine,
Fig. 2 a section on the line A--B thereof, and
Fig. 3 a section on the line CD of Fig. 1.
The stitch plate I9 is carried by a yoke la, and below the same, at the sides of the saddle 8, there are benders 2, 3, in this example bevelled rolls of 5 abuts against a coiled spring in tending to hold it against one of the limbs of the guide. The guide 9 is adjustable lengthwise of a slot II in the yoke la, the guide having a stud l2, into which is screwed a screw II, which can be turned by 0 means of a button I. By this means the benders 2 and 3 can easily be adjusted in relation to the saddle 8, without affecting the compression of the springs ID.
The work fed over the saddle lies under the slot in the stitch plate 19, and a pivoted bender, indicated by broken lines at 24 in Fig. 2, is for each stitch rocked so that it presses the cloth through the slot into the path of the needle. In this respect the mechanism is similar to mechanism shown for the same purpose in the specification of my Patent No. 1,828,789, and illustrated therein in Figs. 4, 5, 6 and 9.
The lateral benders 2, 3 ensure that the work lies smoothly on the saddle and is presented to the needle without rucks or creasing.
What I claim as my invention and desire to secure by Letters Patent of the United States is 1. A blind stitch sewing machine having in combination with a stitch plate and a work saddle thereunder, two levers separately pivoted at opposite sides of said saddle, springs against which said levers abut, adjustable holders for said springs, and work benders carried by said levers.
2. A blind stitch sewing machine having in combination with a stitch plate and a work saddle thereunder, two levers separately pivoted at op- I posite sides of said saddle, springs against which said levers abut, a yoke supporting said stitch plate, adjustable holders for said springs carried by said yoke, and work benders carried by said levers.
