To all whomat may concern:

Be it-known that we, J'AKOB Gnon'and Comm) citiz'ensof the Rep Switzerland, and residing, respectwel New York, p Jerse have invented a new and useful Cuttin Machine for Embroideries, of

which. the followin is a specification.

' Our invention re ates to-machines used to scallop embroideries and the ob ect of our. to provide, a confirst,v and. cutting. instrument, 0rd reliable guiding meansimprovement are, tinuously movin and second, to a for. the cuttin instrument.

We attain these objects by the mechams'm ustrated in the accompanying drawing, in which- Figure lis a vertical side elevation of the entire-'machine;-Fig. 2, a detailed.top view of the controlling, electric contacts;-'F1g. 3, a

detailed plan of the controlling magnets and.

Fig. 4:, shows the embroidery under the gindingand cutting members.

endless cuttingwir orband 1, passes over andfis driven y the pulleys 2. and3. The pulley 2 is rotatably mounted upon the arm 4 which is journaledto the u right 5. Aspri'ng' 6, fastened to the top 0 the up- 7 right 5 keeps the saw 1 under tension. The

are upon the axis 0 The embroidered -36 arepu1ledthrou the machine e rollers 40. and 41', an ke t vertical axis, upon pulley 3; is rotatably' mounted upon the wicket 7, which is fastened to. the upright screws. A. smaller pulley 8 integral with the pulley 3 is driven by the belt 9, which receivesits motion through ulley 10. The main iriving belt runs over t e pulley 10 which is Srotatably mounted intothe up right'5. Thelatter is rotable around its cone 12. is held. 1n: a suitable bearing 14, while the cone 13- is adjusted by the set screw 15 and nut 16 on the bracket 17, the latter being;

part of the machine frame. It will now be clear that the cutting tool 1 can runcon tinuously in the direction of the arrow and thatit' canbe swun back and forth in an the upright 5, for the puraose of following. the design43 Fig. 4,. of e embroidery-36 Figs. 1. and 4.

with a slot 44 in the form of an arc, holds the goods 36 against the cutting tool 1'.

To swing the cutting tool lalong the con tour 43 of the embroi naled central with. the axis of the u right 5 andis provided with a feeler- 35' rghtly pressing against the embroidery 43 and4fol-' lowing its contour, the said pressingbeing,

obta ned by he spring48 wound 'around andfastened to the pivot pin 45 and to;, the upr1ght. 5. Also mounted upon the rod there s a contact spring 32 charged with an electric current. This spring 32, when the feeler 35 is back and forth, is, over thestationary con-- ductor-segments 21'--30' transmitting cur rent. to a certain number of the segments, the number of segments. actuated uponbeing always thesame, but theindividual se entsi included in that number chan 'ng. with the movements of the feeler35. pair of see- $191181 magnets or'so1enoids46', 471 when energized, are actuating; a.v coreIQ mounted upon an extension- 18 of the upright 5., .The mags nets46 and 47 are built up in: sections, each one of which is energi, dv individuallywbfi one of the segments ofth'e" arc.33'. It 7 thus. be seen that as many sections ofthe' magnets 46, 47 will be energized, as here are segments on the etc 33 covered by the spring 32. A change in the position: of the spring 32 change the sectionsenergized of the magnets of suchan extension that it covers just the field of so many sections as are energized at one time. Supposing'that' sections 20,21, 22, 26, 27, 28- and 29 areener 'zed the core will go into the osition, 1n mated on the Fig. 2.. Moving; t e. spring 32 one segment 'overthe are 33 will; for instance, energize the sections 23 in addition. to-theaforemem tioned sections, but will. at the-same timede energize the section29. This causes' the core. 19 to swing over to agnet 46 for the width. of the section 23, thus turning also the-upright5 and the cutting tool 1. Inthis way" cry a. rod 34- is jourso I 46 and 47;- The core 19. is I the saw lmay follow continuouslythefeelen 35,.allf'thettimercuttingofi the-waste 42 a1ong; the contour of'the em roidery 43.. Thesegments 33 and: the magnets 46 and 41' have naturally to be subdivided very finely to 'do the saw I exactly along theedgeof t -e embroidery, so that no appreciable. step by step movements are made.
