This invention pertains to tinsel winding machines and more particularlyto that type designed to wind what are known in the trade as tinsel icicles.

The main object Ofthe present invention has to do with an improved means for grasping and holding the end of the strand of tinsel prior to the beginning of the winding operation thereof about a' forming mandrel.

A still further object of the' invention resides in the provision of means whereby the grasping means just mentioned may be expeditiously operated both in. the gripping or grasping operation as well as in the release of the tinsel ;-a feature which materially speeds up production. i i

With these and other objects and advantages in view, as will hereinafter appear, ref- 7, erence is bad to the "annexed drawings,i wherein:

Figure 1 is a perspective view of the machine with the table broken away, the oper ating foot pedals Omitted and with a portion of the icicle wound about the mandrel, Figure 2 is a side elevation of the machine with a portion of the mandrel supports broken away and the mandrel advanced to that position where the free end of the tinsel may be placed upon the mandrel so that it will be clamped when the mandrel is retracted, I a

of standard 4 is a sleeve 5, the same being held in place by a'lockcollar 6 mounted onthe rearwardly extending portion thereof, a washer 7 preferably being placed between said collar and the standard. i v Extending through the collar, and also through a bearing in standard 3, is a shaft 8 which at its: left hand end in the mechanism as shown is, formed into a taper mandrel 9 polyg'- onal in cross section. It will be appreciated, ofucourse, that the mandrel proper could be made; separate'and fixed to the end ofthe shaft; Also secured to shaft 8 inward of the standard 3 is a gear 10 and interposed between said gear and collar 6 isa" coiled springjl'l normally under compression and tending 'at alltimes to retract or move shaft. 8 .to'the right. A wheel 12 is I signed to contact a driving wheel 13 when the. latter is moved into contact therewith. V Said wheel 13- is secured to the shaft of an electric motor 14, which latter is so mounted on the, table that it may be rocked to bring the wheels into Operative contact. f flAs will be seen upon reference to Figure 4, the 'rear'portion of the motor base overhangs the edge of the table 1 and underlying such V portion (the rear legs of the base) is a shaft l'5extending lengthwise of the tableand supported for rotation in any suitable manner. Secured to the shaft and underlying the motor base are blocks, as 16 which,'when' the shaft is turned clockwise, lift the motor. Shaft 15 maybe actuated in any suitable manner but preferably by a pedal (not shown) connected toa draw-link 17 whichin' turn is pivotally connected to a crank-likeportion 18 of shaft 15. This arrangement provides means whereby the operator has secured to shaft and is do complete control of the driving mechanism to start and stop the same.

In order that the motor may be rocked' or tipped to bring driving wheel 13into contact with the wheel 12 the inner portion or legs of the motor base are held to table 1 by screws 19 which pass through enlarged openlngs 20 A spring 21' encircles each screw and takes against the under face of the head and against 1 a washer 22 which rests upon the upper sur point adjacent the end of element 18.

face of the motor leg. This arrangement allows the motor to be-rocked for the purpose above described. I

It is designed,of course, to feed the tinsel lengthwise of the mandrel as the latter is rotated andvafter the free end of the tinsel has been clamped in place with reference to the mandrel.

The clamping and feeding mechanism will now. be described. I

Shaft 8'is movable endwise through the. bearing, in standard 3 and sleeve Said sleeve is keyed to the shaft, the key being deretracted, forms a clamp for the free end of the tinsel which is to be wound about the mandrel 9 upon rotation thereof. l j

8 With a view of moving the shaft endwise so that the groove 24 will stand outward of thesleeve in order that the end of thetinsel may be inserted in the groove I may employ any suitable mechanism. In the instant case the shaft 8 at its rear or right hand end is formedwitha socket 25 into which extendsa screw 26 adiustably mounted in the upper end 1 of a lever 27 fulcrumed at 28 upon a suitable fixed supporter element as 29. v

Rigidly affixed to lever 27' is an armor second lever 30 which, as shown in Figure 1, ex-

tends over the edge of the table 1 andat a draw-link 31 is pivotally connected to the end of said lever 30 and a pedal, (not shown),is connected thereto for'drawing the link 31 V downwardly andfroc king lever 27 through lever 30 with a consequent endwise movement of shaft .8 and compression of spring 11.

. By arranging the draw rods 17 and 31 adjacent each other the operator will have ready control of the machine through depression of the pedals attachedto the rods just mentioned. e

When the pedal controlling the draw link 31 is released spring 11 will immediately retract the shaft and mandrel and grasp the end of the tinsel which has been introduced into the groove 24. The tinsel is relatively 7 are in their retracted position, as shown in Figure 3. This arrangement permits of the ready insertion of the free end of the tinsel uponthe mandrel.

in the groove and the clamping of the tinsel by retraction of the shaft.

Pinion 10, whichv is secured to shaft 8, meshes with anidler 34 mounted upon a stub shaft, the gears being of such width as to always be in mesh whatever may be the position of the shaft 8. Idler 34 meshes with a gear 35 secured upon a shaft 36, the outer or forward end of which is provided with a screw thread as at'37'. The screw is-designed to cooperate with the tinsel feeding and advancing means, best shown in Figures 1 and 5.

Extending from the standard4 are two fixed rods 38 and 39 which at their outer ends have secured thereto a plate 40 carrying an adjustablethrow-off arm 41. The rod 38 forms the support for the tinsel feeding mechanism. Such mechanism. may be said to comprise an inverted L-shaped member 42 provided with elongated bearing sleeves 43 and 43? through which, and through the member 42, the rod 38 freely extends. In other words, the member 42'is pivoted for swinging motion upon the rod 38 toward and from the feedscrew 37 Adj acent the screw 37 the member 42 is provided with threads complemental to the threads'37 anddesigned, whenthe parts are in engagement, to advance the member 42-toward, the end of the mandrel 9. The tinsel,

denoted by T, passes about and over a grooved wheel 44 and over a fixed finger 45 secured to the upper end of the member 42 with its forward endextending laterally and over which the tinsel passes just prior to its being wound To hold the tinsel within; the grooved wheel 44 and to smooth it out there is present a pivoted block 46 normally held in contact at its forward end with the tinsel within the groove by a spring 47 secured to themember'42. This member maybe held in its upright position by merely turning it upon its pivot when it is desired to'thread the tin sel over the wheel 44.

The tinsel T will preferably pass through a tension element 48 of any approved type, said tension member being mounted upon the outer end of an arm 49 which at its inner end'is secured to the member ,42iand moves therewith. Preferably the tinsel will be taken from a spool, as .50, mounted in any suitable support upon the table 1 and any tension mechanism, as 51, may be employed to prevent the spool from unwinding too rapidlyor from unwinding through possible breakage of the tinsel. v In operation the tinsel is drawnfrom the spool through the tension device'48 about and over the wheel 44 after which the block 46 lSD'lOVBd to itslowest position, as in Figure 5, and the free end of the tinsel is inserted in the groove 24, the shaft 8 and the mandrel 9 at such time being moved forward 7 spring 11 draws the parts back to the position shown in Figure 3 at which time the end of the tinsel will be clamped and firmly held in position. The operator then draws down upon the link 17 which rocks the motor, as above set forth, and brings the wheel 13 into driving relation with the wheel 12. Motion.

is thus imparted to the shaft 8 and mandrel 9. Motion is also imparted to the shaft 36 and the screw 37 with the consequence that the feed and guide member 42 is moved longitudinally of the mandrel toward the outer end thereof winding the tinsel tightly about the mandrel so that when it is released or removed from the mandrel it will maintain the form shown in Figure 6. The feed screw extends beyond the end of the mandrel and as a consequence the tinsel guiding mechanism or element 42 passes beyond the end of the mandrel and upon continued rotation of the shaft 8 the tinsel will be broken ofi at the outer end of the mandrel. At, or-just after, this breaking operation the member 41 will contact the beveled face 52 formed upon the lower end of the member 42 and thus swing the member 42 so as to withdraw the threads formed thereon from the screw 37 This operation is not essential as the operator may, of course, withdraw the member 42 from engagement with the screw 37 through manual operation. Rotation of the shaft 8 is then stopped and the shaft .8 moved outwardly releasing the clamped end of the tinsel at which time the completed tinsel icicle may be removed from the mandrel. It of course has a slight tendency to expand and thus'there is no difficulty with reference to its removal from the mandrel. After a completed icicle has been withdrawn the operator swings the member 42 rearwardly to free it from engagement with the screw 37 and moves it toward the standard 4. The free end of the tinsel, which at that time extends beyond the member 46, may be inserted into the groove 24 when'the shaft is again moved outwardly as above stated.
