ATTORNEYS,
THADDEUS S. GRAHAM, DE LOS ANGELES, CALIFORNIA.
DUPLEX NEEDLE-PLATE FOR SOLE-STITCHING MACHINES.
Application filed April 22,
To all whom it may concern:
Be it known that I, THADDEUS S. GRAHAM, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Duplex Needle- Plates for Sole-Stitching Machines, of which the following is a specification.
My invention relates to combination needle plates for sole stitching machines and consists of the novel features herein shown, described and claimed.
My object is to make a knife needle plate for channeling a sole ahead of a needle, and a lip needle plate adapted to cover the channel cutter so as to avoid the necessity of removing one plate and replacing the other.
Figure 1 is a perspective of a sole stitching machine equipped with a combinat on needle plate in accordance with the principles of my invention.
Fig. 2 is a fragmentary perspective showing the operation of sewing a leather sole with the knife needle plate, the lip needle plate being thrown out of use so as to channel the sole.
Fig. 3 is a view analogous to Fig. 2 and showing the operation of stitching a rubber sole, the lip needle plate being thrown over the knife needle plate so as not to channel the sole. I
Fig. 4 is a sectional view illustratlng the operation shown in Fig. 2.
Fig. 5 is a sectional detail illustrating the operation shown in Fig. 3. i
Fig. 6 is a perspective of the knlfe needle plate.
Fig. 7 is a perspective of the lip needle plate.
Fig. 8 is a perspective of the two plates connected together.
Referring to Fig. 6 the details of the knife needle plate are as follows:
The flat rectangular body 1 has a tongue 2 extending from one end, there lfieing a screw hole 3 through the center of e body 1, and a screw hole 45 through the tongue 2. The plate is made from heavy sheet metal, and the parts out from the sides of the Specification of Letters Patent.
Patented June 8, 1920.
1919. Serial No. 291,883.
Referring to Fig. 7 the lip needle plate comprises a rectangular body 9 having flanges l0 and 11 extending downwardly to fit the sides of the body 1, a needle hole 12 to aline with the needle hole 7, and a hinge bearing 13 to fit between the bearings 5 and 6. A screw 14 is inserted through the bearings 5 and 6 through the bearing 13 to connect the lip needle plate to the knife needle plate, as shown in F 8.
The knife needle plate is placed upon the v sewing machine horn 15 and secured in place by screws 16 and 17 inserted through the screw holes 3 and 4, and when it is desired to stitch a leather sole 18 to a shoe 19, as in Figs. 2 and 4, the lip needle plate is swung upwardly and outwardly out of the way and the sole 18 is placed upon the body 1 and moved toward the needle hole 7 with the knife 8 cutting a channel 20 in the leather ahead of the needle.
When it is desired to stitch a rubber sole 21 to the shoe 22 the lip needle plate is swung over on to the knife needle plate, as shown in Figs-3 and 5, and the sole 21 is placed upon the face of the lip needle plate and passes above the knife so that no channel is formed in the rubber sole.
Thus I have produced a combination needle plate for sole stitching machines in which the lip needle plate fits upon the knife needle plate when the use of the knife needle plate is not desired, and in which the lip needle plate swings away from the knife needle plate when the use of the knife needle plate is desired thus avoiding the necessity of unscrewing one plate from the machine and screwing another plate upon the machine. This is an important matter especially in repair shops where the work alter nates from channel to unchanneled jobs.
Various changes may be made Without departing from the spirit of my invention as claimed.
1 claim:
A combination needle plate comprising a knife needle plate having a needle hole and a grooving knife, means for fixing the needle plate upon a stitching machine and having a hinge adapted to carry a lip need-1e plate
