SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 522,828, dated July 10, 1894.

i Application tiled January 10,'1894. Serial No. 496.417. `(lTo model.)

the seam is produced by the usual elements of a shuttle sewing machine and which is provided with a universal feed, with a braiding spool, with suitable passages for the braid and with a braiding guide, which can be turned together with the universal feed of the machine by means of the crank handle, while the needle bar and the shuttle do not participate in said movement but remain relatively stationary as in the ordinary shuttle sewing machine. i

In the accompanying drawings which form part of this specication, Figurel represents an elevation and Fig. 2 a front view of the machine. Fig. 3 is an elevation of the slide for driving the needle-bar. Fig. .tis a `front elevation of the head of the machine, showing a modiiied form of the connections for driving the needle-bar. Fig. 5 is a vertical section on the axis of the needle-bar. Fig. 6 is a cross-section on the hollow tube M. Fig.

7 is a detail in plan Yof the nut L, and Fig. 8 i

is a detail in sectional elevation.

The hollow needle bar A is set in motion by means of a slide B having aheart shaped cam B represented in Fig. 3 and which is similar to that employed on 'the Singer sewing machines. The heart slide B operates the bar A either directly as represented in Fig. 5 or by the intermediate action of a lever C which is driven by said heart slide as represented in` Figs. l, 2, and 4. where the `heart slide B operates lever C which turns on its fulcrum a and which drives the vertical slidebar D and the horizontal arm E. In Fig. 5 the needle bar A and the central tubes of the machine are represented in sections of full slze.

On the head of the machine is secured `a column F, Fig. 1, which supports the bracket K, upon which is mounted the oscillatory spool holderG of the braiding spool H. The

of the machine by means of pinions 2, 3, 4, 5, 6, 7, 8, 9, l0, 11, 12 and 13. Pinion 13 turns with the bracket K and to its hub the holder G is secured. The braid q passes down from spool L(` through the passage b in pinion 13, Fig. 5) thence through a similar passage c Figs. 5 and 7) in the nutL, which is actuated either directlyby the heart slide B as represented in Fig. 5'01' by the intermediate lever C as represented in Figs. l, 2 and 4. The braid q thence passes through a groove CZ in the central tube M (Figs. 5 and 6) in which the needle bar A plays and is thence guided into the braiding guide N which is secured to the tube O and which can also be turned by the crank handle by means of the pinion 9 which is secured to the tube M. The needle bar A is provided at its upper end with a square or flat part g (Figs. 1 and 2) which plays in the frame I and which prevents the bar from turning. vided with a small cylindrical boss h which enters nut L (Fig. 5) and is held therein by means of the latch m (Figs. 5 and 7) so that the needle bar is' reciprocated vertically by the motion of the heart slide B without participitating in the axial motion of nut L. The nut L in its up and downward motion plays on two rods n which are secured to pin- `ion 13 (Figs. 5 and 8) so that the nut L canbe turned during its up and downward motion by said pinion from the crank handle of the machine. In Fig. 4 the needle bar A is secured directly to the transverse arm E ofthe bar D by means of screw p and in this case the nut L can be entirely dispensed with.

The universal feed-bar y in this machine is not secured to the central tube but is placed ipon a secondary shaft Q as represented at fig. 2.

The object of the intermediate lever C is to permit the application of the present invention to such existing machines as have not suihcient space to admit the long stroke of the heart slide whichis required on shuttle machines, and such length of stroke is there` fore obtained by the action ofl lever C on the bar D and on the horizontal arm E.

and which requires no description.

IOD

The thread from the spool Q (Fig. l) is passed through the tension and thread guides of ordinary construction down through the hollow needle bar A and is then threaded into the needle. By the construction and arrangement of parts shownand described the slide for driving the needle-bar is actuated directly from the main shaft W, instead of from a supplementary shaft, as in machines devised for doing similar work.

We do not claim the combination with the elements of a shuttle machineot a universal feeding mechanism, as such combination has been extensively used for many years in machines for sewing elastics to shoes and gaiters.

l. In a braiding machine having universal feed-mechanism and stitch forming mechanism, the combination with the needle-bar, the actuating slide therefor, the nut L connected and turning with the universal feed mechanism and also connected and reciprocating with said slide, and means connecting thencedle-bar to said n ut, so that the former reci procates with the latter without participating in its axial movement, substantially as described.

2. The combination with the stitch forming mechanism and the universal feed mechanism, of the braid-holder connected with a pinion of the universal feed-mechanisn1 so as to follow the motions of the operating handle thereof, a nut provided with a braid-passage and also connected With the operating handle of the feed-mechanism so that it moves with the braid-holder, means for reciprocating said nut, and a needle barconnected with and reciprocated by said nut', substantially as described.

In testimony whereof we have signed this specication in the presence of two subscribing witnesses.
