T BOBBlN INSERTING AND EJECTING' ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 351,992, dated November 2, 1886.

' I Application filed June 27, 1885. Serial No. 169.950. (Model) To all whom it, may concern:

Be it known that I, CHARLES MIEHLING, a citizen of the United States, and residingin New York city, in the county and State of New York, have invented a new and useful Improvement in Bobbin Inserting and Ej ecting Attachments for Sewing-Machines, of which I declare the following to be a full, clear, and exact description, such as will enable any one skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference ,rnarked thereon, which form a part of this specification.

The invention relates to the parts of the machineemployedinplacing,holding,andejecting the bobbin,and hasforits object to provide simple means by which an empty bobbinmay be removed from the bobbin-holder and a full bobbin introduced and securely held in sewingmachlnes that employ disk-bobbins like the bobbins used in the Wheeler& Wilson sewingmachine, and that employ bobbin-holders like the bobbin-holders of the Wheeler & Wilson machine.

The invention consists of the mechanisms hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a broken away and showing my improvement; and Fig. 2 is a front elevation of the same.

Like letters of reference indicate like parts. Fig. 1 shows in full and in dotted lines the two positions of theparts assumed in use.

A is the bed-plate of the machine,havi mg the usual front slide, B.

O is the hook, carried on the shaft D.

E is the bobbin-holding block and drop,carried on the usual slide of the frame and secured by the usual set-screw, and having the usual spring, G, to bear against and hold the revolving bobbin. The pivoted bobbin-holder e is hinged to the block 0 in the usual way and adapted to drop down or away from the revolving hook, permitting the introduction or While the block 6 alone .is beveled at a, if desired both the pivoted bobbin-holder e and the block e may be beveled at a, so that the pivoted bobbin-holder e is allowed to fall on the set-screw e, if it is desired to give said bobbin-holder more play on removal of a bobbin. This pivoted bobbinholder 6 has heretofore been held up in place against the confined bobbin by a spring catch and lever adapted to be directly operated by the hand when the removal or introduction of a bobbin was desired, or to be operated through intervening levers and links, pivoted rods,and springs, such as are shown in Patents Nos. 310,954 and 310,955, issued January 20,1885. My present improvement does entirely away with this meansofoperatingthe pivotedbobbinholder 6, substituting therefor the apparatus about to be described.

Thespring F may be of any convenient form, so long as it has two portions connected so that the one bears against the pivoted bobbin-hold-' er e and holds it up in place coincidently with the other projecting into and so obstructing the bobbin-funnel H, and so that when the latter portion of the spring is forced'out of its obstructing position the former will thereby be forced out of its holding position, and the pivoted bobbin-holder e be thereby allowed to fall. The spring may be secured to any fixed part of. the machine. I prefer the particular form of spring and connection of parts shown in the drawings.

' The slide B has a hole cut in large enough to permit of the easy passage of the bobbin, and has a bobbin-funnel, H, to guide the bobbin into place against the hook.

follows: When it is desired to'open the bobbin-holding device to eject an empty bobbin and at the same time introduce a new bobbin, all that is necessary to do is to insertabobbin into the mouth of the bobbin-funnel H- and press it down firmly with the finger. The bobbin in passing down presses against the spring spring 1 prefer to locate in the slot h, as shown in the drawings) in the funnel H. By this pressure the spring F is so acted upon that it recedes from its position at rest and allows the pivoted bobbin-holder e to fall down or away from the revolving hook at the same time the machine is set in motion, and by natural action of the revolving hook the empty bobbin is ejected and the full one takes its place.

If it is desired to remove a bobbin already in the bobbin-holder without feeding it with F at the point of obstruction (which part of the.

The operation of my improved device is as I another one, all that need be done is to press any suitable ihstrn 1nentsuch as a screwdriver or a Hat piece of iron, or, perhaps, the fingeragainst the spring F at its point of obstruction in the bobbin-funnel H, after having set the machine in motion, as described, when the bobbin will be ejected. A new bobbin may also be introduced into the bobbin-funnel H while the machine is running and in full motion, when the empty bobbin will be ejected and replaced by the new one by selfaetion of the spring F, in combination with the natural revolution of the revolving hook O.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In Combination with the revolving book 0 and the pivoted bobbin-holder n of a sewinglnaehine, the bobbin-funnel H, the pivoted bobbin-holder c, and holding'sprin g F, projecting: into said funnel, whereby the introduction of a bobbin into the bobbin-funnel H causes the pivoted bobbin-holder etofalhand its removal therefrom causes thcsaid pivoted bobbin-holder 0 to spring up to place, substantially asand for the purposes set forth.

2. In combination with the revolving hook C and the pivoted bobbin-holder e of asewingmachine, the slide B, the bobbin-funnel H, the pivoted bobbin-holder e, and holding-spring F, projecting into said fnnneLsubstanti-ally as and for the purposes set forth.

3. In combination with the revolving hook O and the pivoted bobbin-holder e ofa sewingmaehine, the bobbin-funnel H, having slot h, the pivoted bobbin holder e, and holdingspring F, projecting through said slot into said funnel, substantially as and for the purposes set forth.

4. In combination with the revolving hook C and. the pivoted bobbin-holder e of a sewingmaehine, the slide B, having the slotted bobbin-funnel H, the pivoted bobbin'holder c, and holding-spring F, carried on said slide and projecting through the slot into said funnel, substantially as and for the purposes set forth.
