T0 aZZw/wm it may concern: v.

' Be it known that we,1MANLIo TERRAGNI and TEOBALDO BoLDIzzoNI, subjects of the King of Italy, residing in New York, in the county of Bronx and Stateof New York, have invented certain new and useful Improvements in Embroidering. Devices, of which the following is a specification.

Our invention relates-to an improved embroidering devi.ce,-adapted to work artistic designs in thread upon pieces of cloth."

An object of our invention is to provide an embroideringdevice which is simple in its make up; embracing relatively few parts, and which is capable of being operated easily and efficiently by hand to produce the desir'edresults.

Other objects of our invention are to provide an embroidering device having means whereby the length of the stitch and the length of the stroke of the thread-actuating element, such as the needle, can be conveniently adjusted; and so constructed that the thread-actuating element itself serves to move or feed the device over the cloth from'one point to another, in practice.

Further objects and advantages of our invention will appear from the following description, taken in connection with the accompanying drawings, which illustrate what we regard as the best forms of our invention; and the characteristics of our'in vention are defined in the appended claims. This disclosure, however, is explanatory only and we reserve the right to make changes in the shape, size and arrangement of parts, without departing from the scope, and spirit of our inventionto the full extent indicated by the generalmeanings of the terms and variations vof phrase in which, the claims are expressed."

Specification of Letters Patent. Patented Aug, 1920, Applicationfiled August so, 1919. Serial No. 320,888. r

the body of the device. This body is furnished at its lower end with an open presser foot 2, united to the body by legs 3. Above the legs, the body is tubular and it may be formed out of a single piece of metal, cut and bent into the required shape. In

the tubular portion of the body is a reciprocating plunger 4 connected to a holder 5 for a thread-actuating element, such as a needle 6. The holder 5 projects from the lower end of the body and the needle is movable upward and downward through the foot 2; while the plunger 4 projects from the upper end of the tubular portion of the body 1 and carries at its outer end a slidinghead 7 to which is attached both ends of a band 8. This band forms in effect a ring to encircle the finger of the operator and enable the plunger to be moved up and down to work the'needle 6.

In practice the user graps the tubular portion of the body 1 between his thumb andsecond finger, inserting the first or index finger through the ring 8., He then presses the foot 2 against the cloth and moves the plunger up and down with his index finger by means of the head 7 and ring 8 to make one stitch after another.

The plunger 4 may be simply a, channelshapedpiece of metal and theholder may beftubular, inserted into the plunger at one end and receiving the needle at the other. The legs 3 are provided with inclined edges 9 at the back, and the holder'5 has a pair of projectionslO which engage these edges when the needle makes its downward stroke Consequently when the device is in use and the head 7 is pressed downward, the needle will be first moved in a direction that is substantially perpendicular. to the surface of the cloth, which is to be embroi'dered; butafter the point of the needle pierces the cloth, the projections 10 strike the inclined edges 9, and the remainder of the movement of the needle is in a direction downward and to the rear. The backward component of the movement of the needle has'the effect of impellingthe presser foot 2 forward and thus moving the device into proper position for the next stitch.

We arrange to regulate the length of the stroke of the needle by providing notches 11 in the edges of the plunger 4 and in engagement with these notches is an adjustable stop 12. This stop hasthe form ofa strip which slides up and down in the'tubular portion of the body 1 with the plunger 4; and at its outer or-upper end itis bent over and widened to enter the notches.

WVhen the plunger 4 is depressedfar'enough to carry the upper widened end of this strip 12 against. the upper end of the tubular portion of the body 1; it can go no farther.

For a short stroke, the stop should be in these arms rearward beyond the inclined edges 9 on the back of the legs 3,, a variable portionof those edges can be rendered ineffective; and the projections 10 caused to engage the inclined edges 9 at a lower point in the stroke of the needle 6. The lower the point at which the projections 10 engage these edges theshorter is the distance over which the needle is given a slantwise backward movement, and therefore the shorteris the stitch. Before the" point of the needle pierces the cloth, the projections 10 strike the arms 13. After the needle goes through the cloth, the projections 10 strike the edges 9.' Hence, the'movement of the needle to impel the presser foot forward does not take place until the needle engages the cloth that is being worked. The arms maybe tightly riveted to the legs, so that they'stay set by friction.

The lower part of the holder 5' is provided with a pair of lugs 15 just below the projections 10, and through these lugs is passed a pin mounting a cam16. This cam locks the needle in the holder and enables the needle to be removed merely by turning the cam downward by means of the handlel7.

The head 7 carries a pin 18 which moves in slots19 in the sides of the 'upperpart of the plunger 4. This pin and slot engage ment of the head 7 with the plunger 4 enables the head to slide to some ektent inthe plunger; and the plunger maybe provided at the top with a front portion 20 sothat it encircles the head on all sides. The plunger 4 is provided with an opening 21 in the portion 20 and with a similaropening 21 in the back, and the head 7 may have a passage 22 tomove into and out of registry with the holes 21. The thread from a ball 'orspool is passed through the holes 21 and passage 22;

. down to a thread-guide .23 in the lower end of the holder 5; and then through the eye of the needle 6. When the plunger is forced downward the holes 21 register with the passage 22 and the needle can draw the thread freely; but when the upstroke is given to the needle 6, the head 7 is pulled to draw now be clear.

the passage 22 out of registry with the holes 22. Thusthe thread is held fast in the holes 21. l

The mode of operation of the device will A piece of cloth with a design marked thereon is secured in a frame; and the design isthen worked over w1th threadby" the operator taking hold of the body 1 between his thumb and second fingerand moving the needle up and down with his index finger through the ring8; the

length of the needlesstroke and the length a of the stitch being first adjusted as explained above. ward stroke through the'cloth, the needle makesa straight stitch on the face of-the On its forwardpridowncloth bearing the design. On the upper rea small loop is left on the side opposite to where the stitch is formed. See Figs. 5 and 6. The body 1 is held-firmly with the foot 2 pressing tightly against the face of the cloth turn stroke, the head 7 binds the thread and 24 which is to have the design, the cloth face being held so that this face is the upper face, whilethe face where thexloops 25 are made, will be the lower face. The loops are due to the slack in the thread, partly taken up by the upward movement of theneedle after making each stitch 26. a

In Fig. 7 I show a modification wherein the arms 18 on the legs 3 are dispensed with. Instead of these arms, a threaded shank 13 is fixed to the holder 5 near the projections 10, this "shank extending rearward, and receiving a member or nut 27. to bescrewed against the plunger 4. Normally, the holder 5 is set so that on the downstrokethe projections 10 strike the edges at :a relatively high point, butby turning thenut forward, they can be caused to engage by the edges 9 at lower points, making thestitches shorter.

The nut thus makes variableportions of the edges 9, ineffective, like the arms 13.

As shown in Figs, 1, 5 and 6, the '13 i are in such position as to screenthe full length of the edges 9, .but obviously they will be pushed forward. as far as is desired whenthe deviceis innse. a j The plunger 5 may belong enough toproject at both ends of the bodyil whenthe needle is at the end" of itsworking stroke, and the holder5 is disposed in the plunger so that the projections 10 are near the lower end thereof. v A spring 28, providedby bending down the upper end of the-holder keeps the holderin tight frictional engagement with the back of the plunger andthe stop 12in front, pressing the stop against,v

the inside of the body. The holder-may also have pro ections 29, near the spring 28 to enter notches 3,0 in theplnnge'r4, so'that the plunger, as it moves, will cause the d plunger are require holder to move' with it. Thus no fastening :deviceS for the holder. and- Having described our invention what We believe to be new and desire to secure and protect by Letters Patent of the United btates is i j 1.
