UNITED STATES PATENT y, OFFICE.
JOHN C. RING-E, OF BRIDG'EPORT, CONNECTICUT, ASSIGNOR TO THE SINGER MANU- FACTURING COMPANY, A CORPORATION OF NEW JERSEY.
BOBBIN-CASE FOR SEWING-MACHINES.
Specification of Letters Patent.
Application filed May 20, 1911.
on the construction represented by United` States patent to O. H. Rudolph, No. 619,791, dated February 21, 1899, and consists in arranging the slide, which secures the bobbin or cop to its case, and its actuating lever in the same plane instead of in super-posed relationship as in the patent referred to, thus reducing the thickness of the bobbincase without interfering with the capacity of the inclosed bobbin or cop.
In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a vieW in substantially central section of a bobbin-case equipped with the present invention, Fig. 2 a perspective of the bobbin-case cap, Fig. 3 a detail in perspective of the bobbin-case slide and its actuating lever and Fig. 4 is a view in substantially central section of Fig. 2 on a line Vtransverse to that shown in Fig. 1.
As the present invention has to do only with the construction and mounting of the bobbin-case slide and its actuating lever, both of which are carried by the bobbincase cap, it has not been deemed necessary to illustrate the shuttle in which the bobbincase is mounted, nor only so much of the bobbin-case base as is important to an understanding of the invention.
1 represents the bobbin or cop, 2 the bobbin-case cap providedfwith a downwardly eX- tended tubular portion 3 and opening 3', 4 the bobbin-case base having formed integral With it a pin 5 which receives the tubular portion 3 and is provided with a circular groove 6, as in the patented construction previously referred to.
7 represents the bobbin-case slide' mounted in undercut guideways 8 and 9 formed on the outer surface of the cap 2, said slide being preferably provided with a downwardly extended flange or bobbin-retaining device 10 for gripping and lifting the bobbin from its seat in thebobbin-case base, as will later be explained, a spring 11 acting on the shoulder 12 to resiliently hold said slide in the direction indicated by the arrow t, or in the direction to position the catch 13 in the groove 6.
14 represents the bobbin-case slide actuating leverpivoted by pin 15 to the slide 7 and provided with a toe piece or cam 16 arranged to engage the integral portion 17 of the bobbin-case cap. When the lever 14 is lifted or swung outward, the cam 16 acts upon the portion 17 to force the slide 7 backward in opposition to the resiliency of the spring 11 to withdraw the catch 13 from the groove 6, thus releasing said slide from engagement with the pin 5.
The linger 10 is normally out of contact with the bobbin 1, but when the lever 14 is raised and the slide 7 is thereby moved to disengage the catch 13 from the groove 6, said finger is caused to engage one of the flanges of said bobbin and thereby retain the latter within the bobbin case cap 2 so long as said lever is in its raised position, a screw 18 acting, in the absence of said bobbin-retaining finger, to limit the backward movement of said slide. The lever 14 is intended to serve as a convenient handle when positioning the bobbin in the base 4, and is slightly undercut at 19 to facilitate its manual manipulation outward.
20 represents the commonly-employed bobbin-thread tension spring, and 2l the bobbin-case base liange which, as in earlier constructions, is mounted in a suitable groove formed in the shuttle (not shown).
Claims 1. A bobbin-case for sewing machines comprising a cap provided with a tubular portion, a base provided with a pin having at its free end a groove, a resiliently held slide mounted on said cap and normally held in operative relationship with said pin, and a lever pivoted to said slide which, when raised, serves to disengage said slide from said pin, said lever being arranged parallel with at the side of and in the same plane as said slide.
2. In a bobbin-case for sewing machines, a cap provided with a tubular portion, a
ybase provided With a pin having at its free end a groove, a resiliently held slide provided With a bobbin-retaining inger, said slide being mounted on said cap and normally held in operat-ive relationship With said pin, and a pivoted lever operatively connected With said slide which, When raised, serves to disengage said slide from said pin and to move said bobbin-retaining finger lin gripping Contact Wit-h the bobbin, said lever being arranged at the side of and in the same plane as said slide.
3. In a bobbin-case for sewing machines, a cap provided with a tubular portion, a base provided with a pin having at its free end a groove, a resilient-ly held slide provided With a catch and a bobbin-retaining finger, said slide being mounted on said Cap' and normally held in operative relationship with said pin, and a pivoted lever operatively connected With said slide Which, when raised, serves to disengage said catch from said groove and move said bobbin-retaining linger in gripping Contact With the bobbin, said lever being arranged parallel With at the side of and in the same plane as said Slide.
ln testimony whereof, I' have signed my name to this speoiiication, in the presence of two subscribing Witnesses.
