Before starting upon a detailed description of the present invention, reference is first made to the general elevational views in Figs. 17 and 18,

' wherein is illustrated at right angles a convenbeneath the work table T and at the left of the reciprocating needle 59 shown inFig. 17 is pivotally mounted a pin 60 which corresponds to the pin ID in Fig.1 of Scharf Patent 1,798,110,.

or the pin 13 in his Patent 1,994,406. It is unnecessary to show further details regarding this pin and its relation to the sewing machine for they are well described in; these patents. The pin 60 coacts with or enters the axial cylindrical opening inone end of the ornamental tip ll, clearly shown in Fig. 1. It-will be noted that this umbrella tip is provided also with thread engaging means here shown as a transverse hole slightly nearer to one end of the tip than the other for reasons hereinafter explained. This hole 36 during delivery is first adapted to be engaged by a carrier arm 64 and then moved laterally and slipped over the pin 60, as shown in Fig. 3, whereupon the arm 64 swings upwardly and moves to the right, thereby leaving the tip ll free to be engaged by the needle 59, which carries the thread through the hole 36 in the tip in operative relation to the looper beneath the work table T prior to making the next stitch to one side after the other of the tip, as fully described in the method patent to M. M. Scharf, above noted.

Heretofore this positioning operation had to be done by hand, that is, the operator selected one of the ornamental tips from a receptacle of any sort and positioned the same manually upon the pin 50 with great care to assure that the hole 36 extending transversely through the tip I l was vertically disposed and in registry with the path of travel of the needle 59. If, for example, the hole 36 in the tip shown in Fig. 3 where at an angle to the path of reciprocation of the needle, then the needle or tip would break as the needle impacted the tip, probably necessitating a replacement of the needle and rethreading of the machine with material loss of time. The present machine operates in a manner as will be hereinafter described and the operator knows that the tip is properly placed upon the pin 60 with the transverse hole 36 in registry with the path of travel of the needle.

Referring now to the general positioning and arrangement of parts, attention is directed particularly to Figs. 1, 3 and 5, wherein is shown a hopper ll) of any convenient size and material adapted to contain a plurality of ornamental rib tips II. This hopper has a chute l3 (Fig. 5) of a Width and thickness adapted to permit a natural free horizontal feeding by gravity of the tips H which are constantly stirred or agitated by means of a beveled reciprocating plunger l4 passing over an opening l6 located in the front face It of the hopper In to the chute 13. This plunger I4 is mounted in a suitable guide (Fig. '5) and is reciprocated by means of a link l1 pivotally connected at its upper end to the plunger M by means of the pin l8 and pivoted at its lower end on a pin i9 eccentrically mounted upon a disk is driven by the shaft 21 mounted in suitable supporting bracket 22 on the base 9 of 'the machine, as shown in Fig. 3. 1

It will be noted that a gear 23 (Fig. 3) of the worm type meshes with a pinion 24 keyed to a drive shaft 25, which in turn carries a larger gear 26 meshing with a smaller pinion or gear 21 on shaft 28, which may be considered the main driving shaft for the various mechanisms herein shown. The purpose of this reduction gearing is to insure a relatively slow reciprocation of the agitator plunger l4 within the hopper Hi, thereby tending to prevent breakage of the tips or tossing them out of the receptacle, as might otherwise'occur if violent agitation took place.

The'hopper iii is provided with a movable lower bottom door 29, as shown in Fig. 5, normally urged to closed position as by any suitable means such as well-known'spring hinges, the purpose being, to permitafq'uick discharge or removal of the majority of'these tips when desired, for it frequently happens one wishes to change the color of the tips to agree with the color of the cover used onthe umbrella, and by such a construction a change of the tips may be accomplished very quickly,especially when taken in connection with the interchangeable magazines hereinafter described with relation to Figs. 27 to 30.

; .As the tips H are fed to the chute l3, it will of course be obvious thatunder normal circumstances approximately 50% will point in one direction and the other 50% in the opposite direction. Therefore it is necessary that some means he provided for insuring that these tips, when they reach the pin 60 (Fig. 3), for example, they will bein the correct position to be mounted thereon. This may be done in several different ways,'only two of which will be herein illustrated and described.

At the lower end of the chute I3 is a revolving drum or magazine mounted in an outer shell I! having a base secured as by means of screws 8 tov volves in a clockwise direction, engages the tapered or bevelled edge of a cam 38 to be retracted into the central position shown in Fig. 6. Thus, with the parts in retracted position, "the tip designated at A in Fig. 6 will be free to rotate about its axis and the inner surface 31 of the outer casing l2 will rotate the tip as the wheel or magazine rotates, thus bringing the transverse open-' ing 36 into position to be engaged bythe pin when released from the cam and, when in, such position, the spring 35a will force the pin 35 through the opening, thus holding the tip in that position throughout the rest of its travel about" the drum or approximately through the remain ing three hundred degrees of arc.

When the tip reaches the position shown at the top of its cycle, as in Figs. 5 and 8, it is then 1 ready to be engaged 'by the feeder arm 64 and carried out of the magazine and on to the sup- P rting pin 60.

This transfer mechanism is better shown in Figs. 8 to 11, inclusive, wherein is shown the pin 60, the reciprocating needle 59 and the upper part only of the rotatable magazine. The sides of the magazine are cut away to permit a pusher bar or rod 66 to pass completely therethrough, as shown in Figs. 3 and f8. This'rod '66 is pivotally mountedat the upper end of a lever5l, which Fig. 10 it will have caused'one of the ornamental tips to be carried'out of the magazine by-reason of the split end of the carrier "pin 64 riding down the surface of the cam block-'65 to engage the hole 36 in the tip as illustratedin Figg-Q. This downward swingof the carrier pin 64 occurs when the lever 5| has moved toward the left only a very small distance and is caused to swing downward by means of the spring 69a, most clearly shown in Figs. 6 and '7', engaging the arm 69Lto Which'is securedthe carrier pin 64. The

upper end of the: arm69 is connected to the end of the pusher rod 68 in such a manner to allow the arm to'swing aboutits pivot asshowniin Figs. 8 and 9 which illustrate thismovement. Just as the endof the carrier pin 64 has completely entered the hole- 36of the tip, "'the forward end of the pusher rod 66 has contacted the'rounded head 7 of the tip (Fig. 9) and from this point'the two lever is in turn mounted upon a stud, 5"! carried by bracket 58, the lower end of which "lever extends below the work table Sand'is adapted to be actuated bythe knee of an operator against the action of a return spring 5 l was shown in Figs. Hand 18.

Fig. 17 shows these parts in actuated position,

and. when pressur upon the lower end of the arm 5| is released, then the upper part of lever 5|, as shown in Fig. 3, moves towards the ri'ghtto retract the rod 66 entirely from the'rotating per tion of the magazine. The pusher rod 66 is connected with bar 6|, whichrides in a suitable slide bearing 63and has pivotally mounted between its forward end and the end of a'pusher rod '68 an arm 69 that supports the tip carrier 64. As shown in Fig. -8, the bar BI is at its furthest position or at a point Where the lever 5| has been moved to its extreme right or neutral position. Referring to Fig. 3, it will be noted that after thislever 5! is actuated to the position shown, a segmental rack 56 carried thereby, meshing with a pinion 55 secured on the shaft 48 mounted in the bearing block 58a, causes a rotation of the disk 49 in a clockwise direction to the position as shown. Further movement of th lever 5| and disc 49is prevented by the stop pin P carried by the bearing block SBa contacting the pin 49a mounted on the periphery of the disc 49. The counterclockwise movement of the disc 49 and the return of lever to its inoperative or normal position is limited by the pin 4% also mounted on the periphery of disc 49 when it contacts stop pin P on the other side. This same movement may be accomplished by hand if the operator grasps a knob 5|] and. moves it in a clockwise direction a suffic'ien't distance'to accomplish the same result as to positioninFig.3. I

As the lever 5 I moved in the position" shown in pusher rods .66 and 68 move forward --together, pushing th tip out of the magazine, the tip being held between the-ends of 'the carrier pin' 64 and the pusher rod-66. i As thelever 5| nears the end of its movement,the tip H is pushed upon the split end of the pin: 60 as illustrated in Fig. 10. At

this point the shoulder 1| located at the right Y hand end of the pusher rod 68 contacts the stop pin 12, thereby preventing any further'forward movement of the pusher rod'GB; ''-As the lever continues to move to complete the restof its movementwhich is very. slight'at this time,-the bar 6|, upon the end ofwhich the arm 69 is pivoted continues tomoveiorward. This action causes the upper end ofthe arm 69 to actfas the pivot point instead of its lower end and the resultant action causes the end of the carrier pin B4 to bewithdrawn from the tip as shown in Fig. '11. When the pusher rocl68 is stopped by the pin 12 and the lever 5| must continue to. move forward, their points of connection mustchange and this is accomplished, as

.most clearly shown in Fig. 14, bymeans o-rthe arm 1|] pivotally connected to the pusher rod 58 at one end and having its other end pinned to the stud 62 whichis free to slide in'a slot in 66a which slidably engages the "pusherrod 66 by means of well. known pin and slot connection. It'is easily 'seen that'a's the lever 5| continues to move forward carrying'the bar 6| with'it, the

arm 1!] will be turned in a clockwise-direction as shown in Fig. 11. This turning action of theiarm It! also causes the-block B6a'to move forward compressing the spring which normally holds the push rod 66 in itsextended forward position until the ring l3 secured on "the rod contacts theside of the magazine l2. As the block 66a continuesto compress the spring 61, the pin 15 carriedby block 66a engages the hooked end of the flat spring 14 secured to the ring T3 to hold the- push rods 66 and 58 in the position shown in Fig. l1.

When thelever 5| starts to return to the position shown'in Fig. 8 the fiat'spring id continues to hold the push rods in the locked position which causes the carrier pin 64 to remain in raised position to prevent it fromstripping the delivered tip off the pin 6|). As the parts near the position shown in Fig. 8, the shoulder Ha of the push rod 63 contacts the stop pin 12. Thecontinued' movement of the lever 5| causes the stopped push rod 53 to pull the block 66a backward-because of their being connected as already described.-

1 This backward movement of the block 66a bring' 's the turned down end of the flat spring 14 into contact with a releasing screw 16, carried on the lever 51, which forces the end of the flat spring downward away from the pin 15 thereby releasing the.push rod 66 to allow the coil spring 61 to move it forward to its normal position.

When the push rod 68 was stopped by the pin 12 this allowed the bar 6| to release the carrier pin arm 89 but since the carrier pin 64 has been brought back into position over the bevelled block 65 it cannot swing downward into the magazine and comes to rest on said bevelled block 65, as shown in Fig. 8.

If, for any reason, a tip II is incorrectly posi tioned in the magazine, that isas illustrated in Fig. 12 for example, then the transverse hole 36 which is slightly longitudinally off center is not in a position to be engaged by the spring pressed carrier pin 64 as illustrated in. Fig. 9. Consequently, as illustrated in Fig. 12, as the pusher rods 66 and 68 move towards the left, the carrier pin 64 moves downwardly ofi the bevelled block 65, missing the transverse hole 36 in the tip H, and as the forward movement of the pusher rod 56 is continued and the tip is free of the magazine,the carrier pin 54 snaps downward, as shown in Fig. 13, to discharge the tip through an opening in the work supporting table of the sewing machine as illustrated.

This discharge of an incorrectly positioned tip must beaccomplished by a full movement of the lever in order to reset the carrier pin 64 as already described. After an incorrectly positioned tip within the magazine has been discharged, the magazine has been turned one position by the pawl 41 and the operator merely has to actuate the lever 51 again to feed another tip out of the magazine toward the'pin 60.

The pawl 4! is pivotally mounted on the bell crank 43 by means of the screw stud 42 and is held in contact with the ratchet disc 40 by the spring 53 (Fig, 1). The bell crank 43 is supported on the stud 44 which is secured in an extension of the bearing block 58a (Figs. 1 and 2). The arm 45 of the bell crank 43 carries the roller 46 which contacts the hub of the disc 49 and is held in this position by means of the tension spring 54.

Carried on the hub of the disc 49 is the cam 41 which actuates the bell crank 43 upon the return of lever 51 to its inoperative position. The throw of the cam 4'! is such that the pawl 41 will be moved upward the distance of one tooth of the ratchet disc 40 as shown in dot and dash lines of Fig. 3. This movement of the ratchet disc 49 in turn rotates the magazine 30 one position to bring another tip I i into position. The spring pressed pawl 52 also engages the teeth of the ratchet disc 40 to insure perfect registration of the magazine 30.

Another form of mechanism. for discarding tips prior to reaching the magazine is shown in Figs. 19 to 26, inclusive. This mechanism is directly associated with the feed chute I3 and includes a pusher rod 90 actuated by means of lever 81 mounted upon shaft 51, as in Figs. 20 and 21. The reciprocation of this pusher rod 90 is accomplished by means of a connecting link 86, the opposite end of which is eccentrically connected with a disk upon shaft 83 and driven by any suitable form of flexible gearing-such as spring belt 8|, passing about a pulley 80 upon the shaft 28 and the idler pulley 80a which is free to rotate on the looper shaft of the sewing machine.

Thus, at regular intervals, the pusher rod 30, having a split end or pin 91, passes through an opening 9! in the side wall of the chute 13. The pusher rod slides in a suitable tubular guide 89 slidably mounted in the guide block 96 under the action of the lever 8']. As this lever 81 moves towards the left, as shown in Fig. 20, its split pin or end 91 passes through the opening Si in the chute l3 and if a tip is correctly positioned, as shown in Fig. 24, then the movement of the pusher arm 90 is arrested by reason of the engagement of the rounded head of the tip by the split pin end 9?, and the surrounding spring is compressed.

However, if the tip is incorrectly positioned, as shown in Fig. 20, then this split pin end 91 of the pusher rod 90 will pass through the opening 9| and engage the recess 92 in the end of the tip pointed in that direction and, as the pusher rod 90 moves toward the right, the tip will be drawn out of the chute, as shown in Figs, 22 and 25. When the tip is in this position, its shoulder at its head end is engaged by means of spring pressed stripper fingers 93 (Fig. 25) and pulled off of the supporting split pin 91, and drops into a suitable chute or receptacle 94 for discard.

It will be noted that the stripper'fingers 93 are free to move inwardly and outwardly as the pusher rod 9d reciprocates. A sleeve 98 surrounds the spring 95 to prevent engagement between the stripper fingers and spring when the pusher rod moves toward the magazine. and the stripper fingers 93 remain in this position until the pusher rod is withdrawn, whereupon they coact with the ornamental collar about the head of the tip to assure its removal and discard. Since this pusher rod 83 with its split pin end 9'! is reciprocating continuously, it contacts the end of each tipa number of times before the-tip passes onward toward the magazine. This continuousfeeling action for wrongly positioned tips in the chute i3 is provided to insure a steady supply of correctly positioned tips to the magazine should two or m r wr n ly p s ti tips have to be discarded consecutively.

As previously stated, it is frequently desired to change the-color of the tips fed to the sewing machine It has already been explained how they may be quickly removed from the hopper by means of the door 29 (Fig. 5). This however does not eliminate the necessity of the operator having manually to eject the remaining tips-in the magazine and the chute i3 and it is to eliminate all this loss of time that I devised the detachable magazine illustrated in Figs. 27 to 30. In Figs. 27, 28 and 29, for example, the supporting plate $9 carryingthe shaft em and feed ratchet 4i) and its operating parts is permanently secured to the bed or base of the machine above the work table 9. The tip feed and ejector mechanism remains exactly as already described, and it is only necessary to actuate a releasemechanism such as a spring catch iflfl passing through an opening ID! at the base of the removable support portion I02 of the magazine, whereupon the magazine 3!), including its housing I93, support I02 and all of the tips carried thereby, may be removed bodily from the shaft, as shown in Fig. 29, and a substitute magazine is placed upon the shaft 3 la, in accordance with the arrangement in Fig. 27. The magazine otherwise is of similar construction to that illustrated in Figs. 3 and 5, the main difference being that it receives its turning motion by means of a clutch I04.

The operation of this machine is clear from the above description. It is sufficient to state that when the sewing machine is ready for operation the usual clutch is thrownin and then the con-- tinuously running power shaft 28 will drive the other parts first to continuously agitate the tips wthin the hopper, as shown in Fig. 5. Actuation of the lever i manually will cause-a rotation of the magazine, and likewise an operation of the' tip feeding mechanism shown in Fig. 3 to carry the tip from the magazine overto the pin 60 as shown in Figs. 8 to 11, inclusive. If, for any reason, a tip is improperly positioned Within the magazine, then it will be automatically discharged by the mechanism shown in Figs. 12 and 13. If this form of discarding mechanism is replaced, then the'incorrectly positioned tips may be removed by the mechanism shown in Figs. '19 to 26, inclusive, for example. I

When it is desired to change the color of the tips another magazine is easily and quickly substituted by means of the mechanism'and arrangement of parts shown in Figs. 27 to 30, in-

elusive.

It will thus be seen that the present invention comprehends a reliable and efiicient mechanism which may be inexpensively manufactured and quickly applied to machines now in use; thereby greatly speeding up the operation of such machines and eliminating the personal element in applying ornamental umbrella tips to the support on a sewing machine while the same are being secured to the fabric forming the umbrella cover.

Definite assurance is provided for feeding the tips not only in the correct relative position to the support at all times and discard those which are improperly positioned, but to be assured that the attaching hole in the tip isin registry with the line of travel of the needle to prevent breakage of any of the parts and particularly the needle. In short, the invention is adapted to accomplish among others, all of the objects and advantages herein set forth.
