' Application August 22, 1942, serial No. 455313 15 Claims. l(c1. i12-99) This invention relates to spangle machines and has for its object the provision of an improved spangle machine. 1 - _ Machines have heretofore been proposed for sewing pre-formed spangles to fabric. Such ma chines, however, are objectionable because of the fact that the spangles are tiny discs, very thin and very light, `and consequently quite diñicult tomanipulate or to arrange in any regular order sideration of the accompanying drawings which illustrate, by way of example, a spangle machine arranged to punch the spangles out of a narrow work strip and sew them to sheet material which if consists of dress fabric. In these drawings: Fig. 1 is a combined plan and sectional View showing the punching and transferring ,mecha-` so that they can be handled by a feeding mech it-_ nism in plan, the section being taken horizon-` tally through the shank of the presser foot of the anism,A Mechanism for handling such articles is sewing mechanism; ~ ` apt to be complicated, expensive to make and unreliable in operation. Fig. 2 is a view in elevation of the parts of the , V It _has also been heretofore proposed to par machine illustrated in Fig. 1 looking from the after ‘the needle had entered the hole in the with the parts in a different Iposition; -and Figs. 5, 6 and 7 are views of fragments of sheet tially pre-form the spangles, leaving‘them con~ is_ side of the sewing mechanism; Fig. 3 is also a view in elevation but looking' nected together in a continuous strip which was from the front; A fed to the stitching mechanism. Associated with, Fig. 4 is a detailed sectionalview of the punch this mechanism was a reciprocating knife which ing mechanism taken on line 4-4 of Fig. 1, but severed the individual spangles from the strip center of the spangle in the operationof sewing the spangle onto the fabric., This machine ne cessitated that cutting mechanism be positioned ' in close proximity to the needle ofthe sewing erable diiiiculty. Moreover, the character of de signs possible with such a machine was limited because of the fact that it would be impossible to sew the spangles onto the fabric in overlapped relation `to one another. The _object of the present invention is to pro~, vide .a sp‘angle` machine which is capable of both manufacturing the spangles from suitable mate rial andA applying them to the fabric or other sheet material to which it may be desired to at , , i Referring now to these drawings, the machine has an L-shaped frame I which is suitably mounted on the frame of a sewing machine. The mechanism, and this was apt to lead to consid tach them. material having spangles applied to them in dif ferent spacing. sewing machine is provided with _suitable stitch forming mechanism including a vertically rei ciprocating needle 2 and a presser’foot 3, _the needle being operatively connected in any suit able manner with the horizontal main shaft 4 lof the sewing machine, these being the only parts of the sewing machine illustrated. The sewing machine mechanism may be of any appropriate . construction, it being understood that the needle ' 2, presser foot 3 andother parts of the stitch-v . forming mechanismy make one reciprocation and More particularly, the object of the present form one complete stitch for each revolution4 of invention is to provide a machine in which the the sewing machine main shaft 4. , . individual spangles are completely formed from One leg of L-shaped frame I rotatably sup-V suitable material and then transferred individu~ 40 ports an operating shaft 5, this shaft being driven ally from the forming mechanism to the sewing from sewing‘machine main shaft 4 through a mechanism without `losing control of the indi chain 4a and cooperating sprockets having the vidual spangles. same number of teeth, thereby causing shaft 5 A feature of the invention also is the provision of `a spangle lmachine having forming or punch 45 to rotate in timed relation to shaft 4. On the end of shaft 5 there is a small crank having` a ing mechanism Which is disposed suñiciently re~ mote from Ythe sewing mechanism so that the ' design of the punching mechanism will not be restricted or'impaired by its proximity to the sewingmechanism. , ._ _ 4 v a continuous rocking movement to this, arm. 50 Arm 8 is-pinned as shown at 9 to a short shaft I0 which has a bearing in the short arm of the A further object of the invention is to provide a_,spangle machine which is of rugged construc tion `and canbe used for long periods of time with a minimum of servicing. L-shaped frame member I. On the opposite end of shaft I0 and pinned thereto at II `so as to rock with arm 8 there is a feed actuating mem I The invention will be understood from a con crank pin 6 which engages a slotted opening >'l at the rear end of a rock arm 8 so as to impart 55 ber I2 (Fig. 2)“, which will be referred Ato laterfon. The front end «of rock arm 8 actuates a ver ’ 2,390,639 2 tically reciprocating punch carrier member I3. This member viewed from the front is bifurcated at its upper portion and connected by means of a pin I5 to actuating member 8 which is slotted as shown at I4 in Fig. 2. Pin I5 is squared at its central portion so as to ñt the slot I4 and round at each ‘end so as to fit round holes in thei bi yieldable engagement with the teeth 36 by means of a helical spring 39 surrounding the outer end of shaft 34. Ratchet member 38 is provided with a pin 46 which passes through a slot 4I in shaft 34 so that longitudinal movement of member 38 is provided for. ' _ From this it will be understood that on each upward movement of punch carrier I3 pinion 35 furcated portion of the punch carrier. is rotated in the clockwise direction as viewed in Mounted in the lower surface of punch car rier I3 there are two punches-a small punch 10 Fig. 2, as shown .by the arrow, which causes the work strip 2| to be advanced.

The inner end of this radial arm section of swinging arm 45 is secured to a Avertical supporting post 5I. The end of the flex ible portion of the swinging arm 45 in which spangle receptacle 41 is located is preferably made of thin metal so that it may swing beneath the presser foot 3 and carry the spangle 48 to a position where the hole in the spangle is in align ment with needle 2. spangle receptacle 41 has needle 2 of the sewing mechanism makes 3, 4 or any 'desired number of strokes to one revolution of shaft 5, or one operation of the sp-angleform ing and transfer mechanism. In Fig. 7 the gear ratio is 1:3, that is, there are three revolutions of sewing machine shaft 4 Ato each single revolution of operating shaft 5, and accordingly two stitches 51 are placed between each of the spangles. By means of the present invention a machine a substantially U shape in plan view, as shown in 10 has been provided which is capable of forming Fig. 1, the bottom of the U fitting the curvature of the spangle. ' and attaching spangles in substantially a single . operation, that is to say, the spangles are punched The bottom of the receptacle has‘a U-shaped from a strip of suitable material transferred from slot to permit the passage of the needle 2 through the punching mechanism to a sewing mechanism the spangle while it is still held by receptacle 41. 15 and sewed onto the fabric as they are individu Guard member 46 is preferably an edgewise ally punched and without releasing control of mounted arcuate strip so as to provide rigidity them. This greatly reduces both the cost of and enters between’the toes of the presser foot manufacture of the spangles, and the `cost of 3 so las to terminate in close proximity to needle . sewing them on the fabric, or, infother words, 2. It may be secured in position by means of 20 it reduces the over-al1 cost of Spangled dress fab screws 52 on the side of guide bar I8 of the ric. punching mechanism. It will be understood that changes may be It will be understood that swinging arm 45 made in the construction of the machine illus carries spangle receptacle 41 to the sewing mech trated and described above without departing anism an instant previous to the entrance of the 25 from the spirit of the invention. the scope of downwardly moving needle 2 through the aper ture in the spangle 48, holds the spangle in po sition while the needle enters the spangle aper which is set forth in the accompanying claims.
