IMPROVEMENT IN SEWING-MACHINES.
Specification forming part of Letters Patent No. 171,007, dated December 14, 1875; application filed October 7, 1875.
To all whom it may concern:
Be it known that I, SAMUEL WARD FRAN- CIS, of Newport, Rhode Island, have invented certain new and useful Improvements in Sewing-Machine Attachments, of which the following is a specification, reference being bad to the accomponying drawing, of which Figure l is a perspective view of a Singer sewing-machine embodying my improvement; Fig. 2, a detail view, exhibiting the under side of the machine, where the principal part of the improvement lies. Fig. 3 represents separately the attachment to the needle-bar of a Singer sewing-machine, by means of which two or more needles may be employed.
This invention relates to sewing-machine attachments, applicable particularly to sewing-machines of which the so called Singer machine is the type-t. e., machines sewing with two threads, to make what is termed the lock-stitch, by means of a reciprocating needle and shuttle attachment, whereby two or more parallel rows of stitches may be sewed at one and the same time. It has heretofore been attempted to accomplish this result, but so far as I am informed the means employed were inadequate, or of such c0mplex nature as to render its application and practical operation impossible.
The object I have in view is not only to preserve the original character of the machine-i. 6., its capacity of stitching single rows-but to render it convertible into a ma parallel lines.
. The attachment subject of this patent consists of two parts, namely:
First, a sliding and adjustable shuttle-race. This part of the invention consists of mechbetween the guides s and t.
anism by which two or more shuttles may-be worked at one and the same time, as shown in the drawing. Fig. 2. Motion is given by the crank a, through the levers b, c, d, and e, to the main or primary shuttle-carrierf. Attached to said shuttle-carrier f is a slotted arm, g, which drives the second shuttle-can rier h by means of the pin 3, which is capable of moving freely in the slot is l. Slotted arm 9 may be lengthened indefinitely for the pur pose of driving as many shuttle-carriers as the limits of the machine will allow. Shuttle-carrier It Works upon the bars m and n of the sh uttle-race 0 p q 7*, which is made to slide The shuttle race is adjusted by means of a set-screw, v, attached to the bar to of the sh uttle-race, which may be moved along the slot as y, and set at any position, thus regulating the distance between the shnttlecarriers f and h. It will be observed that a series of sliding and adj ustable shuttle-races may be employed.
Second, the adjustable needle-clamp. The primary or main needle c is attached to the needle-bar b by the usual method. The second needle 0 is clamped to the needle-bar at any point of the horizontal slotted arm cl 6 by the clamp f and the set-screw g.
It will be observed that the slotted arm (Z 0 may be extended indefinitely, and that any number of adjustable needles may be employed.
In Fig. 1 I have shown the feed-dog and presser-foot extended to admit of additional feeding-surface for additional rows of stitches. They are extended to reach. that part of the material through which the needle farthest removed will pass.
Having described my invention, what I claim, and. desire to secure by Letters Patent, 1s
1. The combination, with the main shuttlecarrier, of the slotted arm, forming adjustable connection with the auxiliary shuttles, as described, so that the movement of the primary or main shuttle shall be directly transmitted to and partaken of by the auxiliary shuttles, as shown and described.
2. The combination, with the needle-bar, of the primary or main needle, of a slotted arm and adjustable auxiliary needle-clamps, as clescribed, so that the auxiliary needle or needles shall be adjustable on said slotted arm, and the movement of the main needles shall be directly transmittedto and partaken of by the auxiliary needles, substantially as herein shown and described.
3. In combination with the adjustable auxiliary shuttles and needles, arranged and 0perated as described, the elongated feed and In testimony whereof I have hereto set my hand and affixed my seal in the presence of the subscribing witnesses.
