' To all whom it may concern:

Be it known that I, ABRAHAM BALINKY, a citizen of the United States, residin in the city, county, and State of New ork, have invented certain new and useful Improvements in Embroidering-Machines, of which the following is a specification.

My invention relates to embroidering machines and particularly to that type of embroidering machine adapted to be operated or guided by hand for embroidering the desired material.

An object of my invention is to provide an embroidering machine which includes embroidering means and means for feeding the machine; a further object being to operate the feeding means from the embroid ering means.

Another object of my invention is to provide a feeding means for a hand embroidering machine which will positively feed the machine.

Another'object of my invention is to provide a feeding means for a hand embroidering machine which has a member in contact with the material to be embroidered which is given intermittent motion to feed the machine; a further object being to effect the feed on the up stroke of the embroidering needle.

Another object of my invention is to provide feeding means for a hand embroiderin machine which includes mechanism for a justment of the amount'of feeding action; a further object being to Operate such a feeding means from the embroidering means.

Another object of my invention is to provide an embroidering machine having means for feeding the machine by contact of a member with the material to be embroidered and means for breaking such contact while the needle is in the material.

Another object of my invention is to provide an embroidering machine in which the needle is reciprocated along and held from movement out of its axial line and in which the feeding is positively effected by means other than the needle in order to avoid spreading of the fibers of the material; a further object being to provide such alhand embroidering machine with a source of power for operating the mechanism while the machine isv guided by hand.

In the embodiments of my invention illustrated in the drawings," a frame is provided that consists of the tubular member or opbar guide 1, surrounded by a seceratin 0nd tu ular member or base portion 2 which carries or is formed with a foot 3 adapted to contact with the material to be embroidered. The foot 3 carries a web portion 4 upon which other parts may be mounted as hereinafter described. Mounted for reciprocation within-the frame member 1 is a needle operating bar 5 but the needle operating bar 5 may be otherwise mounted upon the frame. A needle 6 is fixed relatively to the operating bar 5 for exam le, as shown in Figs. 1 and 8, by being hel within a recess by means of a screw 7 passing through a slot 7 in the wall of the frame.

In the embodiment shown in Figs. 8 to 13 contact between screw 7 and the top of the slot 7 limits the upward motion of the operating bar. Surrounding the needle is a thread gripping member 8 to which is attached an upwardly extending rod 9 which is connected to the actuating member or handle 10 and which is of such a length that when the actuating member, which is slidably mounted on the operating bar 5 1s ushed down as far as it will go upon the ar 5, the thread gri ping member is free of the lower end 0 the operating bar 5, as shown in Fi s. 2 and 10. But when the actuating mem er 10 is drawn upward it slides u ward on the operating bar 5, as shown in Fig. 9 and draws the member 8 up against the bottom of the operating bar 5 to gri the thread betweenitself and the lower on of the operating bar and lies in the position shown in Figs. 1 and 9. Upon the web 1 of the presser foot there are mounted by means of the pivot-1 1 for rotary reciproca- J tion' or oscillation two members 15 and 16.

A member 18 is pivoted to the lower end of the member 16 by the ivot 17. The member 18 has an arm 19 w ich is guided by the lug 20' in the construction shown in F1 1 to 7 and in the slot 20 (see Fig. 13) in t e construction shown in Figs. 8 to 13 so that the swinging motion of the pivot 17 will result in a backward and forward movement of the feeding member 18 to which is attached a material contacting feedin member 21 which is preferably of flexi le material having a serrated edge 22 and provided with a notch 22' to prevent it from interfering with the operation of the needle as shown in Fig. 12. A projection 30 on the operating bar 5 engages in a slot 31 in the operating member 15 so that reciprocation of the operating member causes a swinging of the member 15. In the construction shown in Figs. 1 and 2 the member 15 is provided with a pin 50 fitting in a slotin engaging member 51 and holding the engaging member 51 in place upon the member 15. Engaging member 51 has a threaded extension 52 which asses through a lug 53 on the member 15 and is provided with a nut 54.

A spring 55 surrounding the extension 52 keeps the engaging'member 51 in its-lowermost position. A fin or 56 on the lmlr 16 engages within a note 57 in the engaging mem er 51. In'the construction shown in Figs. 1 and 2 the feedin member 22 rides over a disengaging mem or 58 formed on the presser foot so that when the needle is pressed down and the feedin member 22 is drawn back, as shown in 1g. 2, contact will be broken between the feeding member and the material and the amount of a.

for each stroke of the needle will be meat-V.

ured by the amount of movement after the edge 0 the contactbreaking member 58 by the members 15, 16 and 18. In order to vary this amount of movement of the feeding member 22 the nut 54' is rotated to change the angular relation of the members 15 and 16 so that the feeding member 22 will slide oif of the member 58 at an earlier or later time during the stroke of the needle.

In the construction shown in Figs. 8 to 13, the member 16 is provided on opposite.

sides of its pivot with projections 23 and 21.

, A flange 25 on the member 15 contacts with 25 and a nut 27 is screwed upon the thread ed part. The nutis .held in position by contact of the corrugations 28 upon it wit 29. Upon the downward motion 7 a spring of the member 15 thenut 27 enga es the rejecting portion 2a on the mem er. 16.

he projection 30 on the operating bar engages wlthin a slot 31 in the member 15 causing it to swing up and down as the embroidering mechanism is operated, and this swinging or rotary reciprocation is imparted to the member 16in a roportion depending upon the amount of st motion respectively between the flange 25 and the part 23 v and between the nut 27 and the part 24. his proportion of the swinging of the member 15 which is transmitted to the member 16 is dependent upon the position of the nut 27 and the reciprocation or intermittent movement of the material contaeti member 21 is thereby controlled.

In order to speed u my 'embroidering machine whileit isgui ed by hand, 1 have provided, in the construction shown in Figs. 1. to 7, a'source'of power supply for the embroidering mechanism. A bracket 60 is clamped upon the guide 1 by means of screw 62 and held against twisting by the key 61;

Projectile downwardly from the screw 62 is a. three ed member 63 upon which is a. nut Gt'held between the ears 65, which are se cured to the frame member 2. A disk 66 is journaled upon the bracket 60 and carries a a gear face 67, which engages a pinion 68 also mounted on the bracket 60 and driven by a flexible shaft 69 or an equivalent means. A

block-70 fitting within'a slot in the disk 66 is connected by a link 71 to the actuating member 10 and is movable within the slot by means of a screw 72 held in place by the collar 73. In operating the embroidering machine it is desirable that the needle shall never rise hi her than the position shown in Fig. land t eref ore when the block 70 is movedaway fromthe center of the disk 66 to increase the extent of reciprocation of the actuating member 10 and thereby cause the needle to be lifted as much above the position shown in Fig. 1 as its movement below feedm member 22 is slid beyond the lower that position is increased, it is necessary to 1201- "unclamp the bracket 60 and draw it down by means of the ut 64.

In former e broidering machines the feeding has been efi iected .by mounting the f I needle so that it will swing automatically as it is pressed into the cloth, or else provi ing means to swing the'needle while it is in the cloth to effect the feedin of the machine. This movement of the needl line separates the fibers of thematerial and e out ofits axial enlarges the hole produced by the needle and furthermore, it-is not a-positive and dependable feed and such a feeding could not be relied upon where the machine is speeded up to hundreds of stitches a minute.

It will therefore be seen that I have provided a machine in which the needle ismoved only along its axial line and which is provided with a positive feeding mechanism capable of feeding the machine at any rate of operation.

In the construction shown in Figs. 1 and 2 the feeding means is drawn up'clear of the material during certain portions of the stroke of the needle so that the machine may be twisted and-turned to follow a pattern. It will also appear from what has been described that l have provided an embroidering machine embodying embroidering mechanism including a needle and the necessary mechanism for operating it and also including a feeding mechanism separate from the needle and which is operated from the embroidering means.

The embodiment of my invention herein described for the purpose of disclosing my invention, is a machine for making that class of embroidery wherein the stitches comprise loops of thread thrust through the material to a greater or less extent and at longer or shorter intervals. These looped stitches may be referred to as turfing but in forming the looped stitches the machine described does not necessarily employ a hollow quill-like needle such as that employed in numerous machines designated in the art by the title Turfing machines. The looped stitches are not locked stitches and apparently are the usual type of stitch made byia machine which is adapted to be moved about over stretched material and having all its parts located on the same side of the material, the parts including a foot constituting the sole supporting means for the machine. A. hand sewing machine making a locked stitch on the other hand has parts located on both sides of the material so as to produce a locked stitch and has a presser foot or the equivalent and a feeding member which grip the. material between them.

While I have described my invention with considerable detail, I do not intend to be limited to the particular features and the constructions described, but intend that my invention shall be defined by the hereunto appended claims.

In the construction shown in Figs. 1 and 2 theamount of feeding for each stroke of the needle is varied by changing the proportion of the stroke oi? the feeding member 22- during which it rides upon the contact breaking member 58 so that in addition to securing the advantage of separating the feeding member 22 from the material while the needle is in the material, the necessity is I avoidedfor a lost motion construction such as shown in Figs. 8 to 13, and} in my copending application, Serial No. 334 444, filed October 30, 1919, of which this application has been made to a certainextent a continuation.
