tweca the lower end of the clothresser earrying bar and the gripping jaws 102, thus securing the cloth-.presser 111 ciiective relav 'tionship with the fabric bein acted upon. end to the connection 65 acting to normally In the use of sewing macines for effect ing embroidery work much depends upon the operator and the object in providing improved stitch controlling means, as herein, is

not only to lessen the responsibility of the vent sizs'of perforations in the fabric. Supposing the spur eyelet 90 to represent the desired size the operator adjusts the fabricwith the spur in the perforation and adjusts the cloth-presser down upon the fabric whernQ if it is desired to ditch an eyelet of uniform radial stitches. the operator adjusts and by winged nut 71 secures the slide 34- to efiect the desired amplitude of vibration of the needle, and during the stitchin opera-5 tion the fabric is manually turned a out the nicer-see spur for one, two or more rotations dependent upon the desired character of product, and at the completion of the formation of the radial stitches the operator moves the cam-lever to its vertical position, thus permitting the spring 6l'to move the camplate 58 in line with the head 42 of the plunger 41 when the operator, through the manipulation of a suitable treadle, rocks the shaft 55 which causes the cam-plate 58 to move the plunger 41, and through the me dium of spring 46 and nut 47, move the segment lever toward the operator at distance suflicient to release the teat 38 from engagement with the opening 40 and with the stationary lug 106 in engagement with the notch 36 formed in said segment-lever, thus holding the latter out of engagement with the segment lever carrier and with the needle in its outside or depth stitch position or in position to form either superposed tying stitching or a circular line of stitches about the eyelet in line with the depth stitches, after which the operator returns the lever 60 to its former position, it being understood that radial stitches of varying lengths may be employed through the manipulation of a suitable treadle connected, as previously described, with the rock-shaft 55. It being un derstood that the spring 46 when depressed is of sufficient strength to overcome the' strength of the spring 52.

When it is desired to do fiat embroidery the spur eyelet is exchanged for a *needleplate and the cloth-presser removed, the fabric being held in one form of commonly employed tambour frame which is manually held down upon the cloth-plate, and as in stitching eyelets, the fabric is manually presented to the action of the needle. in er fecting the last mentioned embroidery the teat 38 is transferred from the opening 40 to the opening 39, thus carryin the segment lever 32 and needle 7 to to left of I their former positions which causes the nec-,

moved laterally equi distant across the/axis of the previously positioned spur 9l'when, through the means previously described, the operator moves the slide 67 in the guideslot 34 to such position as will eli'ect the desired design or figure, the tying ofi or binding stitches being efiected by allowing the slide 67 to position the axis of the stud 66 in aiinement with the axis of the shaft 33,

and during the manualmanipulation of the slide 67 the cam lug 74 is caused to release the tension action of the'disks '77 more or less dependent upon theamplitude of vibration of the needle, the tension device 13 acting uniformly upon the thread during the stitching operation. a

The lug 107 of the segment lever carrier 28 tracks the slot 35 formed in the segment lever 32 and acts to limit the downward movement of the slide 67 when effecting radial stitches as in the stitching of an eyelet, but when the teat 38 of the plunger 37 occupies the opening 39 in the lever 28 the guide-slot 34 is carried to the left of said lug thus permitting said slide to be moved below said lug as when effecting fiat embroidery, the stop determining the limit of downward movement of the slide 67.
