PRESSER-FOOT FOR SEWING-MACHINES.
Application filed July 20, 1915.
presser foot which cooperates with a feeding and trimming and a stitching mechanism for joining or covering the edges of fabric sections.
An object of the invention is to construct a presser foot of the above character having means for supporting the stationary member of a trimi'ning mechanism and also a guiding channel for directing the up turned edges of fabric sections to said trimming mechanism, with needle openings adapted to receive needles arranged in pairs, one in rear of the other, wherein the needles of the respective pairs are staggered relative to each other.
A still further object of the invention is to provide a device of the above character with a strip guide for directing the trimmedbif strip which strip guide is made in sections, one of which is movable so as to facilitate the threading of the needles or the changing of theneedles.
These and other objects will in part be obvious, and will in part be hereinafter more fully disclosed. I
In the drawings which show by way of illustration one embodiment of the invention,
Figure 1 is a view in side elevation, showing a presser foot having my improvements and also the end of the work support, the needle bar and needles. and a portion of the supporting head of the machine, the foot being elevated;
Fig. 2 is a front view of my improved presser foot;
Fig. 3 is a plan view of the same showing also the movable trimming member; and
Fig. et is a perspective view of the presser foot with parts thereof detached and with Specification of Letters Patent.

the strip deflector turned to one side whereby access may be had to the needles.
My improved presser foot consists of the main supporting shank 1, which is carried by a presser bar extending into the socket 2. This presser foot is formed with a main presser foot section 3 which is rigid on the shank l and a yielding or auxiliary presser foot section 4 which is slidingly supported by said shank. section at is formed with an auxiliary shank This shank fits between the lugs 6 and T on the main shank 1 and a cover plate 8 secured by screws 99 to the lug T which holds the auxiliary shank on the main shank but permits the same to slide vertically.
A spring 10 secured by a screw 11 to the main shank 1 of the presser foot, extends upwardly and forwardly over the auxiliary shank as at 12. This spring bears on an upwardly projecting lug 13 formed integral with the shank 5. Said spring normally forces the section 4 downwardly so that the lower face thereof projects below the lower face of the main section 3.
The auxiliary shank 5 is formed with an elongated vertical slot I l and a screw 15 passes through the cover plate 8, the elongated slot 14 and is threaded into the opening 16 in the main shank. This screw limits the downward movement and the lug 6 limits the upward movement of the auxiliary portion 4 of the presser foot.
The main section 3 of the presser foot is provided with two needle openings 17 and 18; and the foot is provided with two stitch tongues 19 and 19 which respectively extend into said openings. The needle opening 18 is in rear of the needle opening 17, and as shown in Fig. 3 said openings are offset or staggered relative to each other in the direction of the line of feed. The needles 20 and 21 enter the needle opening 17 on opposite sides of the stitch tongue 19, while the needles 22 and enter the needle opening 18 on the opposite side of the stitch tongue 19' in said opening. A suitable cross stitch-forming mechanism cotiperates with each pair of needles above and below the material and two independent seams are. therefore, made by the respective pairs of needles, which seams overlap each other as above noted.
The main section of the foot 3 has a for- The auxiliary fill wardlv and upwardly projecting portion 2i. This forwardly projectlng portion is set back from the inner edge of the main inner edge 27. of this portion 26 is spaced from the inner edge 28 of the projecting portion thus forming a tabrioguiding channel 29.
A stationary trimmer blade 30 is seated in a recess in the upper face of the presser foot and is held therein by a clamping plate 31 and a clamping screw The cutting edge of the stationary trmnning member is substantially in hue with the inner edge '28 of the projecting portion 2a. This inner.
edge 28 isin a line passing between the. stitch tongue in the needle openings 17 and 18. Coiiperating with the stationary trimming member 30 is a movable trimming member 33. This stationary triming member is carried by the main fixed section of the presser foot, and, therefore, the edges of the fahricwill be trimmed at a-uniform distance above the lower face of the main section of the foot.
A strip deflector 3st is secured by screws .35 to an arm 36 which is pivoted at 3? to the projecting portion on the main shank l spring .38 is secured to the arm 36 by screws 39. This spring bears against the flat face of the projection carrying the pivot 37 andwill hold the strip deflector in the position shown in Fig. 3 of the drawings. When said strip deflector is turned to the position shown in Fig. l, then said spring bears against the rear face of said projectionand holds the deflector in this position shown in said Fig. 4.
The strip deflector 3-Clis formed in two sections. The section 39 is rigidly secured to the. main section of the presser foot and. extends across the guiding channel The outer end of this fixed section of the strip deflector bears against a vertical. lug 2L0 secured to the auxiliary section l ot the presse-r foot by a screw all. This log serves to prevent the free end of the strip deflector from being forced rearwardly by the fabric. Said fixed section 39 cut awa on its under face to form a clearance for the movable trimming blade As the free end of the strip deflector Inerel rests against the lug 40, the auxiliary section of the presser :toot has free vertical movements.
Themovable section of the strip deflector isrshaped to conform in a general way with the fixed section and the lower edge of said movable section willturn freely above the raised portionsof the presser toot which 7 clamp thestationary trimming member.
The presser foot cooperates with the feed ing mechanism 42 operating at the free end of the work supporting arm The main shank of the presser foot has a rearwardly projecting arm it which is forked at, to so as to slidingly engage the auxiliary presser bar 4:6. This permits the presser foot to be raised and lowered but holds the same from turning on the presser bar or the presser bar from turning, due to thelateral force of the trinnning operation.
