6 Claims.

The present invention relates to yarn package handling apparatus and more particularly to a package carrier arranged for association with a novel supporting truck.

In the handling of carriers of the type mounting a plurality of yarn packages it has heretofore been the general practice to locate the package carrier in the dye vat with .the spindles of the packages in a vertical position and after the dyeing or other treating operation to remove the vation in part section of a modified form of the invention showing in full lines the loading position and in dotted lines the position for carrier I assembly; and Fig. 7 represents a section on line carrier and place it on a support with the packages in the same relative position as when in the vat, namely, with all spindles still vertically disposed with the present day carriers of large capacity holding hundreds of packages, and with three to four packages on each carrier spindle it is exceedingly difficult to remove and replace the packages, With these large diameter carriers it becomes almost impossible for the operator to reach the packages nearest the center of the carrier without danger of injury to his arm from the exposed sharp threads in the end of each spindle,

or without danger of bending the spindles through bodily contact.

Some of the objects of the present invention are to provide an improved method of handling carriers of yarn packages; to provide an apparatus for handling carriers of yarn packages wherein the foregoing disadvantages are overcome; to provide an apparatus wherein provision is made for ready access to any package on a yarn package carrier without interfering with any adjacent packages; to provide an apparatus wherein the centrally located yarn packages on a carrier are brought in position for removal with equal facility to those furthest from the center; to provide means whereby a yarn package carrier can be shifted from its normal plane of operation into another plane convenient for yarn package replacement; to provide a carrier locking means for retaining the carrier in yarn package replacement position; and to provide other improvements as will hereinafter appear.

In the accompanying drawings Fig. 1 represents an end elevation of a carrier handling truck embodying one form of the present invention and showing one form of package carrier mounted thereon in position for the replacement of the yarn packages; Fig. 2 represents a side elevation of the same; Fig. 3 represents a sideelevation of the truck with a carrier suspended above ready for placing thereon; Fig. 4 represents a sectional detail of one form of carrier locking means; Fig. 5 represents a detail in section of the mounting for the locking arm; Fig. 6 represents a side ele- 'I--1 of Fig. 6.

Referring to the drawings one form of the present invention consists of a wheeled truck ill for association with and support of a carrier of the type having spindles II for respectively mounting wound packages of yarn I2. As here shown the carrier has a hollow disc body it! arranged to support the spindles II at opposite sides thereof, each spindle being constructed to communicate with the interior of the body [3 for circulating treating liquid through the yarn packages I2 on the respective spindles. A pipe ll extends axially from the body I3 and has a tapered end ii to form a leak proofjoint with the enacting seat provided in the vat which is designed to receive the carrier, The oppositie side of the body I3 carries an axially disposed post ii of a length greater than that of the spindles, in order that its free end is accessible to attach'a hoisting mechanism. As shown the end of the post I6 is circumferentially grooved to form a head I! having a truncated end face, and therefore when the gripping jaws l8 on the hoist chain 20 grasp the head l1, the carrier can be suspended for movement from one position to another through the overhead trolley of which the chain 20 forms a part.

In order'to support the carrier when released I from the jaws l8, two diametrically located trunnions 2i are welded or otherwise made last to the body i3 and serve as rotatable supporting means to respectively seat on suitable supports.

For the purpose of supporting the carrier and allowing it to be controlled in accordance with the present invention, the truck III is formed with two vertical standards 22 so spaced apart as to receive the body l3 oi the carrier therebetween and allow the trunnions 2| to respectively seat in suitably shaped bearing sockets 23 in the ends of the respective standards 22, Thus when the carrier is lowered by the hoist into position between the standards 22, the trunnions 2| then support the carrier after the hoist jaws [8 are released. When so initially supported the package spindles H are still in the normal, vertical position but by reason of the trunnion action the carrier can now be swung to a position where the spindles II are disposed horizontally. Thus in the new position an operator can stand in front of the assembly of packages and remove and rebearings on the standards 22. tion has been reached the hoisting mechanism is 21 for manual release when-necessary. The cap 7 24 is fast to the upper end of an arm 28 which is mounted for limited swing action on a brace rod 30 of the truck Ill. Thus the lower end of the arm 28 joins a tubular sleeve 3| which is rotatable on the rod 30. A stop 32 projects from the arm 28 to ride in a limit slot 33 formed in a housing 34 fixed to the rod 30. This allows the arm 28 to swing outwardly only far enough to remove the cap 24 from the head l1, and is thus kept out of the operators way.

In operation the carrier may be supported by an overhead hoist in which gripping jaws l8 engage the head I 1 and suspend the carrier in a horizontal position with the package spindles vertically disposed. This is the manner in which the carrier is lowered into the vat for dyeing or other treating operations and is removed therefrom. At the end of a treating operation the carrier is broughtby the overhead trolley into an overhead alined relation to the truck and is then lowered so that the trunnions 2i seat in the When this posireleased and the carrier is then swung to the position where the post I6 is horizontally disposed and in position for registry with the cap 24. This latter is then swung forwardly on its arm 28 and the detent 25 drops into place back of the head H to thereby lock the carrier in position while it is being loaded and unloaded.

While in the foregoing a package carrier is shown, the invention is not limited in this respect as various other types of carriers can be used to carry out the underlying method. Thus the method devised includes as a novel step changing the axial relation of the package spindles from a vertical to a horizontal position or vice versa during the handling of the carrier. In the form of the invention shown in Figs. 6 and 7 the truck 35 is a three legged type supporting a centrally disposed rigid column 36- which terminates in a bifurcated head 31. Pivotally mounted between the forks of the head 31 is a bracket arm 38 carrying an integral tubular elongated housing 40 provided with a somewhat enlarged receiving end 4|. This housing 40 carries as a rigid component part thereof, an axially disposed stem or shank 42 and a portion of which projects from the housing for telescopic engagement with the pipe l4 of the package carrier. This projecting portion is of a size and shape to fit properly within the pipe I 4 and extending well through the carrier body so that the latter is entirely stable when assembled in the shank 42. As shown in full lines the weighted housing 40 is in the position to hold the carrier with the spindles ll horizontal while in dotted lines the housing is shown in position for removing a carrier therefrom or placing a carrier thereon.

In order-to prevent axial displacement of the carrier when in loading position, the pipe I4 is particular type of provided with a flange 43 arranged to seat back of a locking member 44 which is fixed to the head 31 in correct relation for proper cooperation with the flange 44. Thus as the housing swings from a vertical axis to a horizontal axis with a carrier on the shank 42, the flange 43 will seat back of the member 44 and thus prevent axial movement of the pipe l4 relative to the housingthereby ensuring interconnected relation between the support and carrier while the latter is being loaded or unloaded.

Having thus described our invention, we claim:
