"Referring to Figures land 2 of the drawings,

reference character I indicates a standard tele- The wofrthe set screw 3 extending through the base member. A ortlon 4 ofthe standard near its :upper end 'issquare in cross section to which the scroll plate 5 is rigidly attached. The scroll plate is provided with outwardly extending scroll- Ilike .or spiral slots 6. A circular package-supporting plate "I, having a plurality ofradially extending slots 8, is rotatably'i mounted on the 3 upper endof the standard above the scroll plate.

Aeplurality of substantially L-shaped packagegripping-members 9 having depending portions -l l fl are'rmounted on the package-supporting plate with the dependin'g' portionspassing' through the slots ;in thepackage-supporting plate and the ,Jscroll plate. F1A sleeve-likemember H, having an ter slightly greater than the diamtiter of the packaging supporting plate, and a lhub-likexportion l2, islmounted on the standard 'standardis'provided with-a stop'means so {as tote axially and rotatably movable there- .lriof-rub er "or other cushioning material to sup- -port the "sleeve when .the sleeve is in "its lower position. The hub "is provided with .a pin member 14 which may belpressed into .a recess l5 Jextending aroundlthe periphery of the standard "whenx'the *sleeveiswaised, to retain the sleeve xincitszraised :position. The standard maybe protvided with a plurality of such recesses spaced :glonglthetstandard, whereby the sleeve may be *retain'edgin several positions on the standard.

. The.zpackage-supporting plate is provided with "depending guide means 22 "extending through guide holesfz3 in the sleeve-like member "which permit the sleeve-like member to be moved in an axial directlonielative to the :plate and the sleeve and {.the!- plate to lie-rotated together. 'Cover=manipulating members II are carried by the sleeve. and are adapted to bemoved radially :inwardlyand outwardly in the radially extending slots 1 8 in the brackets l9 attached to the bottom of the sleeve. The-slots in the bracketsare in line with the slots in the packagesupporting plate. "The cover-manipulating vmeansextend upwardly through the depending portions of the gripping members and the upper portions of the cover-manipulating means are bent over to form an inverted U-shape as shown by reference character 20. The package-contacting surfaces of the gripping members are recessed to accommodate the cover-manipulating means when the sleeve is in its lower position.

Instead of having the sleeve-like member movable in an axial direction relative to the packagesupporting plate, as described above, the sleevelike member may be attached to a base; and the standard, supporting the package-gripping members and the package-supporting and scroll plates, may be arranged so as to be axially movable and rotatable relative to the sleeve-like member. As in the embodiment of Figure l, the package-supporting plate is supported for axial movement relative to the sleeve-like member and such movement is assured by the rods 22 secured to the plate and extending through apertures 23 in the sleeve-like member. This is illustrated in the embodiment of Figure 8 in which the huh I: is fixed in a supporting bracket 25a and the shaft la (replacing the standard I of the embodiment of Figures 1 to 3) is rotatably and axially slidable with respect to the shell ll. Shaft la is provided with an additional groove or notch 26 to receive detent [4 when the shaft is raised, groove l5 serving when the shaft is lowered. The lower end of the shaft may be provided with a hand lever 21 to facilitate manipulation thereof. The operation is similar to that of Figures 1 to 3 as hereinafter described, but instead of manipulating the sleeve Ila, the lever 21 on the shaft la is manipulated to effect the relative movements needed.

In accordance with the preferred practice 0 the invention; an end portion'25a of a tubular fabric cover member, such as shown in the patent to Pedlow 2,230,067, is drawn over the grippin members and the sleeve, when they cre m the lower position shown in Figures 1, 2 and 3 of the drawing. The other end portion 26a of the cover member is then placed over the tops of the gripping members and cover manipulating members and is inserted or tucked in a gathered condition' in the space formed between the gripping members above the center of the package-supporting plate. An annular yarn or thread package I6 is placed onthe package-supporting plate over the gripping members and the cover member, as shown in Figure 4. The sleeve and the package-supporting plate are rotated relative to the standard and the scroll plate to move the gripping members outwardly to engage and firmly grip the package and also to center the package on the package-supporting plate; The sleeve member is then raised, which uniformly applies the end portion of the cover member engaging the sleeve to the outer side of the package, as

shown in Figure 5. At the same time the covermanipulating members are raised, extending the other end portion of the cover member upwardly, as shown in Figure 5, where it is in position to be readily engaged by an operator. The sleeve member is retained in the upper position by the pin in the hub member which is pressed into the recess in the standard. The upper end of the cover is then folded down over the sleeve memher, as shown in Figure 6. The pin member is withdrawn from the recess in the standard and the sleeve is lowered, causing the portion of the cover member engaging the sleeve to be uniformin overlapping relation to the other portion of the cover member pplied to the outer side of the package, as shown in Figure 7.

The apparatus as shown in Figures 9 to 12 of the drawings comprises a plurality ofyarn or thread package-supporting units mounted on a conveyor and moved to various positions in which they receive protective covering means, then packages, then the covers are wrapped about the packages, and the wrapped packages are removed.

In this embodiment, reference character A indicates generally one of a plurality of units for engaging and supporting a yarn or thread package. The unit comprises a pot-shaped receptacle or member 32 comprising a flat bottom, an upright cylindrical or sleeve-like member or side wall, and an axially extending hub member 33 having an axial bore. The sleeve is fixed'to a plate 34 which is attached to the links 35 of a conveyor chain. The conveyor moves in a closed path and passes over andis driven by the sprocket wheels 36. Means which are not shown are provided for driving the sprocket wheels. A circular package-supporting plate 31, Of slightly less diameter than the inside diameter of the sleeve-like member, is centrally and rotatably mounted on the end of the shaft 38 which extends through 'the'sleeve-like member and the axial bore in the hub member and carries fixedly secured thereto a facing plate 31a upon which the yarn or thread package actually rests. The shaft is adapted to be rotated and moved axially in the bore in the hub member. The packagesupporting plate is provided with a plurality of radially extending slots 3911. A scroll plate 40 is fixed to the end of the shaft beneath the package-supporting plate and is provided with a pinrality of scroll-like or spirally extending slots M. A roller or cam follower 42 is fixed to the end of the shaft. Also a pair of substantially diametrically opposed outwardly extending arms 43 and 44 are fixed to the shaft above the roller. A plurality of substantially L-shaped packagegripping members 45 arranged for axial sliding motion within slots or guideways 39 formed in the facing plate 31a and having depending portions 48 aremounted on the package-supportingplate with the depending portions passing through the slots in'the package-supporting plate and the scroll plate. The scroll plate is urged to rotate relative to the package-supporting plate by the spring means 41 attached at one end to a pin secured to the package-supporting plate and at the other end to a pin secured to the scroll plate. The spring is provided with a U- shaped member 48 intermediate its ends which straddles the shaft to permit the direction in which the spring exerts its force to pass from a position on one side of the shaft to a position on the other side. The spring may rotate the scroll plate relative to the package-supporting plate in either direction depending upon which side of the shaft the direction of force of the spring extends. The package-supporting plate is provided with depending guide means 49 extending through guide holes 50 in the bottom of the sleeve-like member which permit axial movement but not rotary movement of the packagesupporting plate relative to the sleeve-like member. A track 5! on which the roller 42 is adapted to roll is positioned below and extends in the direction of travel of the conveyor. The track is provided with a drop or lower section 52 which l y applied to the outer side of the packagean'd lowers the package-supporting plate during a portion 01 the movement of the package-supporting unit through the apparatus. Cam or deflecting members 53 and 54 are positioned aboveand on opposite sides of the track in the path of the outwardly extending arms 43 and 44 mounted on the shaft. for rendering the unit inoperative comprising the annular plate member rotatably supported on the bottom of the sleeve-like member. The annular plate is provided with handle means H, whereby it may be rotated relative to the sleevelike member about its axis. Guide holes 13 are formed in the annular plate which are' of the same size as the guide holes 50 in the bottom of the sleeve-like member and are positioned so that they may be aligned with the guide holes in the sleeve-like member.

In accordance with a preferred practice of this embodiment of the invention, end portions of tubular fabric cover members such as of the type Means are provided shown in the patent to Pedlow, 2,230,067 are drawn over the'gripping members 45 and the sleeves 32 of the package-supporting units when they are in the upper position at the loading end of the machine as shown in Figures 9 and 10. The uppermost end portions of the cover-members are then placed over the tops of the gripping members and are inserted or tucked in a gathered condition into the cup-like hollow space formed I between the gripping members 45 above the center of the package-supporting units. yarn or thread packages are then placed on the package-supporting units over the gripping mem bers 45 and the cover members applied thereto. As the package-supporting units move along with the conveyor the arm 43 on the shaft 38 strikes the cam or deflecting member 53. This rotates the shaft 38 in a clockwise direction as shown in Figure 11. The rotation of the shaft and the scroll plate in a clockwise direction as shown in Figure 11 urges the package-gripping members outwardly. With this motion, the direction in which the spring extends is moved to the other side of the shaft.. The spring thereby continues to urge the scroll plate and shaft in a clockwise.

direction and the gripping members radially outward. This operation centers the package on the package-supporting unit and retains it in position. The free end of the cover member is then withdrawn from the spac formed within the upper portions of the gripping members 45 at the center of the package supporting unit and is placed over the outside of the upper portion of the package. .As the package-supporting unit passes over the drop or lower portion 52 of the Annular track section, the roller 42 rolling on the track permits the shaft 38 and package-supporting plate package-supporting unit has passed over the drop or lower portion of the track, the package-supporting unit passes by the deflecting member 54 which is positioned on the side of the track opposite to the side on which the deflecting member 53 is positioned. The outwardly extending arm 44 fixed to the shaft 38 of the package-supporting unit strikes the deflecting member 54 causing the shaft and the scroll plate to be rotated in a counterclockwise direction, as shown in Figure 11.

The rotation of the scroll plate in a counterclock wise direction retracts the gripping members moving them radially inward. As the direction in which the spring member extends passes to the other side of the shaft, the spring member urges the scroll plate to continue to rotate in a counterclockwise direction which retains the gripping members in retracted position. The wrapped package may then be readily removed from the package-supporting unit by hand. If for any reason it is desired not to complete the application of the covering means to a certain package, the covering applying means for the unit supporting this package may be made inoperative. This is accomplished by rotating the plate 10 attached to this unit so that the holes 13 are out of alignment with the depending guide members 49. The plate member. in this position prevents the package-supporting plate from moving in an axial direction relative to the -sleeve.member as the unit passes over the drop or lower portion of the track.

Itis readily seen that with this invention the cover is uniformly and evenly placed on the package without rubbing the cover across the package and damaging the thread or yarn.
