'lhiephwgei is eil'e'i'ila'rand 0f a diameter slightly less ihan' ytlia't of the package, and it has-vertiezil movement: wlthm a cage composed of a boi'ion'i pla'te 01' head 2- and stews:

The bottom plate Q-mete upon a-euitable talole 4, which extends 1 laterall from {L Wall or mixer-support, indicated at 5', mid the Sta-Ve 3 are secured co-the edge of theplate 2, 'in any suitable ma nneiyas imvirrsmnce by'serews 6, the edge 01 the plate being notched or recessed -to' receive the sfa'ves,

Cir

which are spaced apart slightly from each other, as clearly shown.

One of the staves indicated at 3 is hinged to the plate 2 as indicated at 7 instead of being rigidly connected therewith, so that the said stave may swing away from the axis of the cage at its upper end. The plunger 1 has connected therewith a rod 8, which extends through registering openings in the plate 2 and table 4-, and is engaged by operating mechanism to be described, for moving the same vertically.

A folding finger 9 is supported at the top of each stave, the fingers being hinged.

to the sta-ves as indicated at 10. These fingers are arranged to swing from the position of Fig. 6 to that of Fig. 2, and they are sector shaped so that when in such last named position they will cover substantially the upper end of the cage.

That is the upper or inner ends of the fingers are beveled, so that each will fit between two adjacent fingers when in horizontal position, with a slight space between adjacent beveled walls, sutficient to receive a double thickness of paper. ing fin or wing 11 is provided at the beveled edges of each finger, the wings being substantially V-shaped as shown, and decreasing in height from the point of the finger outward. The adjacent wings of adjacent fingers cooperate to form between them the pleats to be later described.

Each finger has its lower or outer end bent outward slightly as shown in Figs. 1 and 6, and the said end of each finger is counterweighted as shown at 12, so that normally the fingers occupy the position of Figs. 1 and 6. They are moved inwardly by means of a ring 13 which encircles the cage, and is movedvertically by mechanism to be described. The outward bend or angular portion of each finger is sutlicient to insure that when the ring 13 moves upward, it will engage the inner face of the finger, thereby to swing the lower end outward.

Each of the fingers 9 is reinforced by a longitudinal rib 14 on its outer face and near its upper end, the ribs extending from the points of the fingers about half their length. The finger connected to the stave 3 has two ribs 1 1 which are arranged at opposite sides of a slot 15 extending longitudinally of the finger, and the stave to which the finger is connected has a cam plate 16 on its outer face which moves in a radial notch 17 in the ring 18.

The plunger 8 is moved by means of a hand lever 18 pivoted to the fixed support 5, and having a loop or slot through which the plunger rod extends. Stop collars 19 are arranged on the rod above and below the lever, so that the rod moves with the lever. A pair of rods 20 is connected with the ring 13, and the rods extend through openings An upstandin the table 4:, to a connection with a yoke 21 at their lower ends. The rods are adjustably connected with the yoke, which has a bearing or hub 22 at its center, through which the rod 8 slides.

A hand lever 23 is pivoted to the fixed support 5 below the yoke and the lever has loop or slot through which the rod passes. The lever engages the lower end of the hub, which may be moved vertically by means of the lever to move the ring 13. Stop collars 21 and 25 are secured on the rods 20 above and below the table 4-, to limit the move ment of the ring.

i1. pressing plunger 26 is mounted above the package support. The plunger 26 is pivoted to a hand lever 27 which in turn is pivoted to the fixed support 5, and a spring 28 is provided for holding the lever and the plunger elevated in the position shown in Fig. 1.

In operation the package to be wrapped indicated at 29, of cylindrical form, and usually held in a can 80 or other cylindrical container of sheet metal or the like, is set upon the plunger, within the cage, as clearly shown in Fig. l. The plunger 1 is elevated so that the open end of the tube which is the inner wrapper of the package extends above the cage. That is the package should be in such a position that the top of the container 30 should be level or nearly so with the top of the cage.

The revenue stamp which is arranged to enclose the package, is placed in the container 30 before the package is inserted. The end of the stamp extends above the top of the container, and after the wrapping is complete, it is secured diametrically of the top of the package. In order to prevent injury to the end of the stamp during the folding, and to prevent folding" thereof with the top of the tube the end of the stamp is bent down outside of the can 30, and the can is so placed in the cage that the depending end of the stamp registers with the stave 8 This stave is shown in Figs. 1 and 6, swings outward when the ring 18 is down, because of the excess weight at its upper end, and the notch 17 of the ring permits a considerable outward swing.

l t hen the package has been properly posi tioned, the ring 13 is lifted by means of the hand lever 23. As the ring moves upward, the plate 16 engages the notch, and the upper end of the stave 3 is swung into vertical position. Further upward movement of the ring swings the lower ends of the folding fingers outward, and they are moved from the position of Fig. 1 to that of Fig. 2, forming in the open end of the tube or bag a number of radial pleats 31, as shown in Figs. 2, 3 and 4.

Since the folding fingers are similar, the pleats are also similar and similarly arrangeddiverging from the axis-of the package at equal angles. In effect the folding fingers formin the open top of the tube or bag a number of pairs of radialcrease lines.

lVith the-members of each pair parallel, the material between the members forms the pleat. I

The fins or wings 11 cooperate to flatten or iron the pleats, and when the ring 3 is lowered and the fingers swing outward, the pleats are of the shape shown in Fig. 3.

The pleats may be flattened by imparting a slight" angular movement to the package whenthe parts are in the position of Fig. 2, but preferably the plunger 26 is used. This plunger not only flattens the pleats. and causes them to lie in the same direction, each lapping upon the succeeding, but it also slightly depresses the folded: top as shown in Figs, 6 and aeoentuating' the fold-line, which is the hinge between the top and the side wall ofthe wrapper.

In order to use the plunger 26 the package is liftedas shown inFigfi to thelevel of" the upper endsof the folding fingers, by means of the plunger- 1:. The revenue-stamp may now be arranged on the top ofthe package, and the cover of the can placed:

The dropping ofthe plunger 1 andthe re-V lease of" the lever 27 restores thepa-rts to their normal position.

It will be noticedreferring to Figs. Sand .1-. that the folding fingers. do 'notentirely flatten the right triangular fold, a portion of the folds at the right angle, and opposite the hypothenuse remaining unfiattened. 'ihese portions o-f the folds are conicahand they contact as clearly; shown in the said figures; \Vhen the-folds are brought into contact with the plunger, because of this contact they all fold in one direction. The folding andflattemngmay be aided by 1111- parting a slight angular movement to the iacka 'e as above i'nentioned or to the plunger.
