SEWING-MACHINE.
Specification of Letters Patent.
Patented Sept. 5, 1916.
Application filed July 20, 1912. Serial N o. 710,597.
To all whom/it may concern:
Beit known Vthat I, GEORGE E. MoLYNEUX, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to improvements in feeding mechanism for sewing machines., and is particularly applicable to the sewing of knit goods, the object being to provide a work-feeding element manually controlled to vary the field of its effective action with respect to the line of needle actuation, so that the feeding element and the material may be engaged in the same plane or in different planes, dependent upon whether it is desired to crowd the goods or maintain a uniform amplitude of feed movements of the material.
The invention is designed for application to a Singer 62 class machine, substantially such as is represented by U. S. Patent No. 1,005,645, issued October 10, 1911, to W. H. Hugg, but as it relates only to the construction and application of the feeding mechanism, only such reference will be made to the other elements of the machine as is deemed necessary for a proper understanding of its application,
In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figures 1 and 2 4are front end and plan views, respectively, and Fig. 3 a rear side elevation of the improved feeding mechanism, together with so much of the sewing machine frame and earlier construction of cloth-feeding mechanism as is deemed necesy sary for an understanding of the construction and relative action of the various elements, and Fig. 4 a view in cross section on the line urz-m, Fig. 1.
Referring to the figures, 1 represents the sewing machine frame carrying the needleplate 2, above which is suspended, in a manner common to sewing machines generally, the cloth-presser 3, through which descends the eye-pointed needle 4.
5 represents the main or looper-drivin-g shaft mounted in suitable bearings formed in the sewing machine frame (6 and 7 only of which are shown), the bearing 6 comprising an integral part of the frame, and the bearing 7 being formed in the bracket 8 securedby a suitable screw `(not shown) 'to the front end of the frame 1. The shaft 5 1s provided with the usual adjustable feedeccentric 9 encircled by a strap 10 forming apart of the feed-eccentric 11,;the opposite end of which is pivotally connected with a stud screw 12 threaded into the arm 13 of the oscillating feed-bracket 14 mounted on a shaft 15 secured by screws, as 16, in the stationary bracket 1'7, which in turn is secured by screw 18 to the frame 1.
19 represents the feed-dog-carrying bar secured at one end by screw 20 on a short shaft 21 mounted in the spaced bearing lugs 22 and 23 forming part of the feed-bracket 14, the opposite end of said feed-dog-carrying bar being provided with a downwardly extended portion 24 forked to receive the eccentric block 25 mounted on the eccentric 26, which in turn is secured on the reduced portion 27 of the main shaft 5. All of the foregoing parts are common to the class of machines represented by Patent No. 1,005,645, previously referred to, and are herein shown as representing a preferred form of construction to which the present invention is applicable.
Referring now to the features in construction directly connected with the invention, 28 represents a feed-dog which is provided with the usual serrated feeding surface 29 and pivotally attached by a screw 30 to the head 31 of the feed-dog-carrying bar 19.
32 is a feed-dog-adjusting bar mounted to move endwise in bearing lugs 33 and 34 carried by the bar 19, the bar 32 being pivotally attached at one end by screw 35 to the lower end of the feed-dog, and at its opposite end is acted on by a cam 36 mounted loosely on the short shaft 21 and provided 4with a cam portion 37 and treadle arm 38, the latter being connected by a suitable chain, as 39, to one form of commonly employed treadle (not shown). On the bar 32 is mounted a spring 40 seated at one end against the bearing lug 34, its opposite end bearing against a collar 41 secured by screw 42 on the bar 32 to limit the movements of the latter in a direction toward the cam portion 37, a collar 43 secured by screw 44 acting to limit the movements of said bar in the opposite direction.
From the foregoing it will be understood that When the feeding mechanism is free to be actuated independently of manual control, the serrated surface of the feed-dog Will occupy a plane corresponding to that of the under surface of the cloth-presser, but if it is desired to slightly full or gather the fabrics as they are fed to the action of the stitch-forming mechanism, the opera-tor will, through the manipulation of a suitable treadle operatively connected with the feeddog, cause the serrated surface of the latter to occupy a plane slightly inclined to the under surface of the feed-dog, as shown in dotted lines7 Fig. 1.
Claim:
In a sewing machine, the combination With a stitch-forming and cloth-feeding mechanism including a feed-dog carrying bar provided With a pivotally mounted feeddog, of means including a resiliently and slidably mounted cam controlled feed-dog adjusting bar held against movement about its longitudinal axis for eecting adjustments of said feed-dog With respect to the line of needle actuation independently of the movements of said feed-dog carrying bar.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
GEORGE E. MOLYNEUX.
