PATENT OFFMIF.

SOPHIE FLIEGEL, OF BROOKLYN, NEW YORK.

HAND EMBROIDERY-MACHINE.

Speccation of Letters Patent.

Patented Jan. 4e, 1.921.

Application filed March 22, 1920. Serial No. 367,772.

10 all whom t may concern Be it known that l, SOPHIE FLrnenL, a citizen of Austria, and resident ot the borough of Brooklyn, in the city and State of New York, have invented a new and useful AImprovement in Hand Embroidery-Machines, oiC which the following is a specilication.

The object of my invention is to provide certain improvements in the construction, form and arrangement of the several parts of avhand embroidery machine, whereby its structure will be simplified, its cost ot manufacture reduced, its etlectiveness increased and its product improved.

A practical embodiment of my invention is represented in the accompanying drawings, in which,

Figure 1 represents the machine in front elevation.

Fig. 2 represents a vertical central section taken in the plane of the line 'II- II ot Fig. 1, looking in the direction of the arrows.

Fig. 3 represents a side elevation partly in section with the parts in the positions which they assume when depressed to their limits. l

Fig. 4 represents a similar view with the parts in the positions which they assume when the handle bar has been raised sufficiently to clamp the thread.

Fig. 5 represents a detail view showing the needle adjusted to a different angle.

Fig. 6 represents a transverse section taken in the plane of the line VI-VI of Fig. 2, looking in the direction of the ar rows.

Fig. 7 represents a transverse section taken in the plane of the line VII-VII of Fig. 2, looking in the direction ot the arrows.

Fig. 8 represents a transverse section taken in the plane of the line VIII-VITI, of Fig. 2, looking in the direction of the arrows.

The tubular member 1 of the machine is herein shown as square in cross section and open at both its upper and lower ends. A multiple thread holder 2 may be carried by the tubular member 1, which holder has two uprising pins 3 for receiving the spools of thread 4. The nuts 5 may be screw-threaded onto the upper ends of the pins 3 to retain the spools thereon.

The presser foot 6 is provided with a vertical extension 7 U-shaped in cross section,

which vertical extension is adjustable along a lug 8 projecting from the back wall of the tubular member 1,A for different lengths of needles. In the present instance, the extension 7' is provided with a vertically elongated slot 9 through which a set screw 10 passes into engagement with the lug 6.

The needle bar '11 is herein shown as square in cross section and it is slidable in the tubular member 1 and projects through the upper and lower` ends thereof. A loop 12 is struck up from the back wall of the needle bar near its lower end 'forming an abutment located in position to engage the lower end ot the tubular member, for limiting the upward movement of the needle bar.

An adjustable stop for limiting the downward movement of the needle bar is provided, which stop comprises an inner member 13, an outer member 14 anda set screw 15, which passes through the outer member 14C into the inner member 13, through a vertically elongated slot 16 in the back wall of' the needle bar. This member 111 is provided with sidevflanges 17 over-lapping the side walls of the needle bar for guiding the stop to its different adjusted positions. The needle bar may be provided with a lscale 18 of markings along which the outer member of the stop may be moved to accurately adjust the limit of downward movement of the needle bar.

The needle block 19 is pivoted at 20 within the needle bar 11 at its lower end. The shank of the needle 21 is secured within the needle head by the set screw 22 which projects through a slot 23 in the front wall of the needle bar 11, into the needle head. A bar spring 24 is clamped within the needle bar 11 with its tree end pressing against the front of the needle head above its hinged connection 20, tending to yieldingly hold the needle at the limit of its forward swinging movement. This spring 211 is secured to the needle bar 11 by passing it through slits `formed in the back wall of the needle bar by stamping a loop 25 inwardly therefrom.

The handle bar 26 is herein shown as square in cross section and it has a limited sliding movement in the needle bar 11. This handle bar 26 is provided with a suitable operating handle 27 which acts as a stop to limit the downward movement ot the handle bar. This handle bar is cutaway near its upper end leaving a dat bar extension 28 which extends downwardly along the inside justing the of the front wall of the needle bar l1 to a point a short distance below tl e lower end of the said bar, where the extension is provided with a projection 29 `for not only limiting the upward movement of the handle bar with respect to the'needle bar, but also acting as a clamp for the thread which is lead from the spool l through an eye 30 in the extension, to the needle. rllhe extension 28 of the handle bar 26 provided with an elongated slot 3l through which the needle clamping screw 22 extends.

The means which l have shown for adiorward inclination of the needle for longer or shorter stitches comprises an adjusting nut 32 and its lool; nut 33, both threaded on the needle clamping screw 22, the nut 32 bearing against the front wall of the needle bar 11.

From the above description it will be seen that l have provided a very simple and strong structure in which a common means is employed for adjusting the inclination of the needle and for clamping the needle in the needle head, in which a very simple arrangement is provided for limiting the movement oi' the dierent parts and in which only one spring is employed, viz.,the spring for yieldingly holding the needle at the limit of its forwardly inclined position.

It will also be seen that l have provided means whereby needles of different lengths may be employed by extending and contracting the presser foot.

It is evident that various changes might be made in the construction, form and arrangement oi the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself to the particular embodiment herein shown and described, but

llhat l claim is:

l. An embroidery machine including a tubular member, a tubular needle bar having a limited sliding movement therein, a handle bar having a limited sliding movement in the needle bar, a needle head pivoted within the needle bar, a needle seated in the needle head, a spring engaging the needle head for yieldingly holding the needle at the limit of its forwardly inclined position, a set screw for clamping the needle in.

its head, and an adjusting nut on the set screw for changing the inclination of the needle.

2. An embroidery machine including a tubular member, a tubular needle bar having a limited sliding movement therein, a handle bar having a limited sliding movement in the needle bar, a needle head pivotod within the needle bar, a needle seated in the needle head, a spring engaging the needle head -for yieldingly holding the needle at the limit of its forwardly inclined position, a set screw for clamping the needle in its head, the needle bar having a vertical slot in its wall, and an adjustable stop for limiting the downward movement of the needle bar, comprising inner and outer members and a set screw passing through said slot and engaging said inner and outer members.

In testimony that I claim the foregoing as my invention, l have signed my name this 18th day of March 1920.

SOPHIE FLIEGEL.
