JOHN GONNELLY, OF HALLOWELL, MAINE.

SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 228,611, dated June 8, 1880.

Application filed January 6, 1880.

To all whom it may concern Be it known that I, JOHN OONNELLY, of Hallowcll, in the county of Kennebec and State of Maine, have invented a new and useful Improvement in Sewing-Machines,of which the following is a specification.

My invention relates to a permanent attachment for sewing-machines of a certain class, the function of which is to aid in removing the shuttle from the raceway.

The same consists of a spring-plunger or lifting-rod and a supporting-guide therefor, which are respectively constructed, arranged, and attached to the oil-pan of a sewing-machine beneath the raceway, as hereinafter set forth, and shown in the accompanying drawings, whereby the plunger is made available for raising the shuttle when its removal is required.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of my improvement, the bed of the machine being shown in section transversely of the raceway. Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

A is a curved metal stirrup, in which is fitted loosely the plunger 1), that consists of asmall metal rod fitted at its outer end with a knob, c.

d is a cross-pin carried by plunger 1) to limit its downward movement in the stirrup.

Around the plunger 1) is a spiral spring, 6, which bears on the pin (1 and the under side of the oil-pan of the sewingmachine and presses the plunger b downward.

The ends of the stirrup A are provided with outwardly-bent apertured ends, which are fitted with screws or bolts f, for securing the attachment to the machine.

As shown in Fig. 1, these devices are attached to a Singer machine, the stirrup A being secured upon the under side of the oil-pan B, and the plunger 7/ passing through the pan to a point beneath the raceway G.

When used with other machines the devices will be attached in the same position relative to the raceway, and in some cases the plunger will have to be longer.

111 this instance the shuttle D is shown held by a sliding carrier, E, directly over the plunger or lifting-rod I) and beneath the slide-covered opening in the plate F.

When it is desired to remove the shuttle the plunger 1) is to be thrown up by pressing on knob c, and the plunger coming in contact with the shuttle will tlnow the same out of the raceway or raise it far enough to be grasped by hand. The shuttle may thus be removed with great facility, and much trouble and annoyance saved. The spring 0 returns the plunger downward as soon as the pressure on knob I) is released.

This shuttle-ejector is simple, convenient, and inexpensive, and is permanently attached to the machine.

I am aware that a spring-plunger has been employed for various purposes, and therefore I disclaim it per se; but

What I do claim is- In a shuttle sewing-machine of the class hereinbcfore referred to, the combination, with the shuttle and its carrier and the apertured plate F, of the plunger or lifting-rod b, arranged vertically beneath said opening, the stirrup or guide A, devices f, and the oil-pan to which said stirrup is attached, as and for 'the purpose specified.
