Applcaton filed April 28, 1919.

To all whom t may concern.'

Be it known that I, WILLIAM COHEN, a citizen of the United States, and a resident of Bayonne, in the county of Hudson and State of New Jersey, have invented a new and Improved IIand Embroidery-Machine, of which the following is a full, clear, and exact description,

This invention relates to embroidery machines and has for an object to provide an improved construction over the machine shown in my prior Patent No. 1,265,430, issued May 7, 1918.

A further object, more specifically, lis to provide an adjustment for the needle so as to take long or short stitches as desired.

A further object is to provide a general re-shaping of certain parts including a removable foot having an appreciably wide base.

Another object of the invention is to provide a hand embroidery machine in which the machine automatically feeds itself forward regardless of the adjustment of the needle or needles as to the length of loop provided and without the assistance of any springs directly acting on the needle or its particular holder.

In the accompanying drawing:

Figure 1 is a perspective view of an embroidery machine disclosing an embodiment of the invention.

Fig. 2 is a longitudinal vertical section through the structure shown in Fig. 1.

Fig. 3 is a sectional view similar to Fig. 2, but showing the needle and associate parts in the position occupied at the end of a downward stroke.

Fig. 4 is a view similar to the lower part of Fig. 3, the same having the parts so positioned as to indicate the needle as it is being withdrawn from the cloth preparatory to making a second loop or stitch.

Fig. 5 is a detail perspective view of the foot removed.

In the present invention it is aimed to provide not only 'the ready adjustment of the length of loop with one or a large number of needles, but to provide for an adjustment of the needle or needles so that the needleV or needles may make long or short stitches. In addition it is aimed to arrange the foot so that it will smooth down in a better manner the stitches and hold the Specification of Letters Patent.

cloth more exactly during the stitching operation. v

Referring to the accompanying drawing by numerals, 1 indicates a piece of cloth of any desired kind on which it is desired to provide embroidery of any design. As shown in Figs. 2, 3 and 4 the various loops 2 are arranged on the side of the cloth which is opposite to that engaged by the footmember 3. This results in the embroidery being worked on what is termed the wrong side. caused to contact with the cloth 1 when the device is in use, and together with the tubular frame member 4 to which it is firmly connected preferably by friction forms the frame of the machine. In order that the foot member may be rigidly held in position it has a member 5 which encircles part of the frame member 4 and the rear section 6 of the foot member has a notch or opening 7 to providean openingin the frame to accommodate the screws 8 and 9 hereinafter fully described. The lower or material engaging part of foot 3 is provided with a solid section 10 of any desired size to smooth out the embroidery and to hold the parts in a better position for receiving the loops. By this construction and arrangement of foot the same will be held rigidly or irmly to the frame member 4, but maybe quickly and easily removed. The frame member 4 is preferably square in cross section in order to prevent turning of the parts and to assist in causing the device to operate so as to move in a straight line automatically. Frame member 4 has rigidly secured thereto, or formed integral therewith means for supporting spools 11 and 12 of thread, said means being in the nature of a shelf 13 having upstanding pins 14 arranged thereon on which the spools freely rotate. In the drawing two spools are shown, but only one needle 15, but it will be evident that more than one could be used without departing from the spirit of the invention as disclosed in -my patent above identified. The needle 15 fits into a suitable member or sleeve 21. VIt will be evident that rlhe foot member 3 is' socket in the holder 17. This holder has i when the screw is tightened the needle or needles are clamped lirmly in place. In addition a spring 22 surrounds the screw 9 and acts against the head thereof and against the sleeve 2l so as to have a tendency to swing the needle holder 17 and needle l5 on its pivotal support 23 so as to throw the needle forwardly, or away fromthe back of the foot 3. The needle holder l is provided with an extension 24 against whichthe screw 8 acts said screw being threaded through sleeve 'as desired, said thread-gripping member being turned over at 27 at thelower end. This turned over end 27 is preferably provided with at least as many apertures 28 as there are needles l5 so 'as to guide the 'yarn `or thread 29 to the needles. This thread or yarn passes directly from the spools lor spool as the case may be and is threaded through the openings in theend '27l as shown in the drawing, or in any desired manner to produce the fdesired tension in a simple way.

N ear the upper part vof sliding sleeve 2l and "above the frame member 4 is an auX- iliary sleeve `30 having a set screw 31 where` ylocked in the desired position.

`by this "auxiliary sleeve `may be locked in *any desired adjusted position for limiting or controlling 'the length of the loop 2. The

extreme upper end `of the sliding vbar 25 is provided with a handle 32 preferably more or less ornamental so as to give a finished appearance 'to the machine. I en it is de- 'sir'ed to lengthen the loop 2 so that the embroidery will "be thicker the band or auX- iliary sleeve 30 is moved upwardly and y The distance between the lower 'end of this sleeve and the upper end of thefram'e member 4 determines the length 'of the loop. When it is Adesired to adjust the position of the needle l5 and thereby the length of the stitch, screw i8 is moved in either direction according to the way the needle is 'to be moved.

In operation, when the parts are arranged as `'shown for instance in Figs. 1 and 2 and the thread or threads properly threaded through 'the openings 28 and the eyes of the needles, the handle 32 is moved up and fdown. During the up and down movement of `'this handle the frame member 4 is `grasped yloy'one lhand while the other lhand operates the handle 32. 'The hand grasping the frame member 4 naturally steers or guides the foot and the needle over the design to be embroidered. As the needle moves downwardly the inclined position of the needle in its pivotally mounted holder 17 acts to feed the device forwardly during each stitch. lvhen the device is ready for use and thel needles forced downwardly through the cloth l as shown in Fig. 3, the downward and `also the upward movement act to force the partsin position as shown in F ig. 4, so that as soon as the needle -or needles are withdrawn the spring 22 will act to throw the needles forwardly from the position shown in Fig. 4 to that shown in Figs. l and 2.

llhat I claim is:
