, H 'IGOVER rmsrrrcnmerosrrrou I The present invention relates to apparatus -for sewing attachments to umbrellascovers, and the like, and I more, {particularly to attachments having a single eye or opening, such as urnlcrella tips, and thelik'e:v V

As it is well known, at thepresent -tix-ne the edges of umbrella-covers, particularly that of ladies umbrellas, are frequently not: directly secured to the ribs of the umbrellafbut are provided with tips which are secured at the corners of the-umbrella cover segments and are fitted over the ends of the umbrella ribs, to retain the cover on -thes'ribs. I I l It is the object of the Present invention to provide apparatus of the-character described which will enable one to secure :the attachment named above to-the umbrella cover on the same sewing machine which was heretofore-used for sewing buttons thereon thereby making possible-greateconomyinplantequipment. I v I It is a further;object1of;the present invention to devise apparatus c f the character described which are particularly adaptable to be conveniently and easily used for attaching the tips to v manner that will leave the edge of "the -cover smooth and continuous, and Will -eliminate the necessit for :allowing an excess of material, as

-In :tne accompanying drawing there is shown one embodiment-of the s'ewing, machine and attachmentsnf the present invention; It :is to be understood; however, that such embodiment is shown by way of 'iillustrati'onyonly, to make the principles andm'ractice of the invention more readily comprehensible, :and is not intended, in anyway, "to limit ithe scopeiof :the invention to the-details' therein sho'wn; I

In the drawing? 7 1 Fi'g.-1-i's a view in perspective of one em'loodiment of the apparatus'oi the present invention showing a tip sewing attachment position with a 'tip:arranged'therein; v I I 'Fig. 2 :is a fragmentary top .plan view of the apparatus of Fig. 1; i

required with apparatus at v-presentlirrusejthereby resulting in :the double advantage of economy in the use of -materia1 and a minimum of strain along the edge of" the umbrella cover, at the point where the strainisgreatest. Q

It is the object, generally, .oflthepresent'invention to provide apparatus 'of (the. character described, which is 'of h'ig'hly simplified construe tion, easy andconvenient .to usefwhichis durable and economical, and whichishighly iefficierit rorits purposes; I v

He'retofore "tips were "attache'd"to 'the cover either by hand or by relatively compli'catedmecha'nism especially construetedror, that" purpose.

It is the L general object of the present inven- -tion to provide apparatus wherewith the operations described may be performed "on one-and -'Fig. 3 is :a side elevational view o'fthe tipretai'ningz-arm'shown in Figsrlandvz; y I

Referring more specifically to the accompanying drawing, thegisewing machine, which is .generally designated a's H0, is ;of the general type having a vibrating needle bar =l':l, iin which is arranged the needle 12,.and which moves :the needle laterally and aransversely of the machine,

as well as reciprocating "it perpendicularly to they ever, that any other machine having similar the samema'chine on whichthe buttons are sewn.

'This object is, 'broadly speaking,.1attained by-the provision of novel attachments for button'sewing machines by "means "er I which umbrella "cover tips may be accurately and conveniently held in position to be stitched *to the assoeiateef ra ri-p by thevibrat-irfgfiedleof'themachine."' I

characteristi'cs may be conveniently used.

The machine *fll fhas a work plateg-l 3in which -ther eis arranged the needle plate l 3', having the needle islet" I 4 through which the vibrating needle l '2 is'reciprocated. :The machine is also provided "With'a spivoteddcar, for "lever 4 6, WhichY eXtends Ia'l'o'ng the workiplate ll 3:andsisraisedthereabove, to the free end-of which button guides 'arenoranally Lattached. :In order to convert such machine l 0, f.or :the prur-posesof'thisinvention, there :is :secured near the free end' of the lever it an :L-shaped bracket :l] ,o-ne arm l8 of which-is suppbrteilff romithe lever :l16 "and the other arm 18' at the end of the lever I6 and aipoint opposite the needle bar H and is provided with shoulders 29 and a threaded opening 2|. An arm 22 is arranged within the channel [9 and is rigidly held therein by the shoulders 20 and by the set screw 23 passing through a slot 24 in the arm and engaging in the threaded opening 2|. The arm 22 is arranged to extend forwardly, in direction of the needle and to one side thereof, and is provided with a downwardly offset end, at the extremity of which is carried an enlarged portion or head 25, which normally rests on the work plate 13. The head 25 is provided with an aperture 26,

' is located, preferably, at a point intermediate When the ring 41 is to be secured between two folds of material, instead of to a band, as

is the case when such ring is attached to a foldapparent that the apparatus described, consisting of the attachments shown and described in association with a sewing machine of the character described, provide many advantages. Such apparatus enables the operator to perform the atprovided with the wing portions 3| to support the tip 29 in place. The member 30 is so arranged that it will support the tip 29 in position to have its eye 32 lie directly above the needle slot 14 at a point approximating. the position of the needle at one extreme of its vibrating movement.

It will be readily seen that when. the tip 29 is arranged within the retaining means 30 the edge of an umbrella cover may be placed around the rounded end of the tip, which'projects from the member 30, with the inner face of the cover 33 facing the tip, as is normally required to be done when sewing one object or fabric to another on a sewing machine. The machine is then set into. operation and, as it will be obvious, the needle I2 as it reciprocates and vibrates, will pass, alternately, once through the! eye 32 of the tip 29 and the fabric surrounding it, and once to the side of the tip, either through the fabric or alongside of it, in a chain stitch formation. The cover will thus be secured to the tip by stitches extending only from the center of the tip to one side thereof, to provide a smooth and continuous surface to the edge of the umbrella. cover, without any tucks or folds as heretoforeproduced in machine attachment of the tips.

When the stitching. is completed, the tip 29 may be easily removed'from its retaining means 30 and turned to face the inside of the cover 33,

and when in that position may be seated over the end of an umbrella rib, in a manner well known to those skilled in the art.

The arm i8 maybe provided with a groove 35 defining shoulders 36 and with a threaded opening 3! and adapted to receive a second arm 38 in substitution for the arm 22 when the latter is removed from its place. The arm 38 extends directly toward the needle 12 and is provided with a downwardly offset end, which normally rests on the needle plate 13' of the machine; the

said end being provided, preferably, with a forked extremit 39, passing about the needle slot 44. Also provided on the end of the arm 38, directly to the rear of the needle slot 14, is an upright pin or post 48, which is arranged in such position relative the needle [2 that when a button ring 4! is arranged about the post and held thereagainst, a portion of such ring 4| may be arranged over the needle slot M in position to permit the vibrating needle to pass to either side of the portion of the ring lying over the needle slot, so as to stitch a fabric about the ring, in a'manner which will be readily understood.

tachment of all accessories to an umbrella cover or case on the same sewing machine, and makes it possible to accomplish that with relatively small and simple alteration, by the relatively easy sub- 'stitution of asingle, simple and readily accessible part of the machine. The attachmentssubstituted are of simple construction and economical to make and use.- They are easy to assemble and dismantle and require no particular or new skill to operate.

What I-claim as my invention'is:
