' 1s claims. (c1. zzo-so) inr their wet state to containers, such as bottles and the like, whereby the bands may be rapidly and easily applied in position ,over the necks Y 15 of the containers or bottles.

` Another object is to prov1de an apparatus about which a part thereof bands are placed and then spread or extended a predetermined distance by the said apparatus to permit the apl paratus to easily, quickly and eiliciently positio`n\\the band about the neck of the container.

A5, still further object is to provide an apparatus having an extensible portion about which hydrated cellulose bands are placed and extended a distance sumcient to'perrnit the apparatus or 25 tool-` to be easily and quickly inserted about the neck of a bottle whereby the band'will be inserted over the neck of the bottle when the device is withdrawn.

Still another object of the invention is to provide the me od of placing hydrated regenerated Acellulose bands about the neck of a bottle which consistsin inserting a wet bandabout collapsible jaws off a device, inserting the jaws over the neck of "a bottle whereby the jaws will be arranged between the neck of the bottle and the exteriorly positioned band, tripping the device vso as to bring the jaws'together'and then withdrawing the collapsed jaws from the bottle so 40 that the band will be in proper relative position in respect to the bottle neck, the band shrinking tightly about the neck of the bottle while being dehydrated. A still further object of the invention is to 45 provide continuously operating vmechanism containing a plurality of devices about which hydrated regenerated cellulose bands are arranged whereby the necks of the bottles may be quickly inserted in a device as it moves to application 50 position whereby a lband will be placed about the neck of the bottle, the plurality of devices being movable constantly in position whereby a great number of bottles may have bands applied about the necks thereof within a very n short space of time.

l.but at right angles thereto.

Another important object "of the invention is the provision of -an applicator for use in c'onnection with applying seal bands on` bottles whereby bands may be applied to bottles, the bands being actually smaller than -the bottles 5 would normally require as the applicator stretches the bands. considerably and permits easy application thereof.

Numerous other objects and advantages will be apparent throughout the progress of the following specication.

The accompanying drawings illustrate a selected embodiment of the invention andthe views therein .are as follows:

The hand operating device or applying bands to the closure end of containers, such as bottles, is shown particularly in Figs. 1 to 6, and referring thereto 10 designates a handle provided with a vertical bore 11 through whicha rod I2 extends. The upper end of the 50 bore Il merges with a bore I3 of larger diameter. A cap I4 having a plunger end I5 is removably -fastened to the rod I2,' and a spring I6, ar-

ranged about the cap I4 and the upper end of the rod I2, is seated in the larger bore I3 and 55 apparatus for extending pairs of spaced vears 2D and 2I..

Downwardly

extendinglinks

22 and 23 are pivoted to the pairs of ears `2l) and 2l respectively as indicated at 24. Oppositely disposed arcuate jaws 25 `and 26 are fastened to the lower ends of the

links

22 and 23 by means of reinforcing elements 21 and screws 28.

Links

29 and 30 have their outer ends pivotally connected atv 3l to the downwardly extending

links

22 and 23 respectively, and their inner ends pivoted to the rod I2 as indicated at 32. ',The yoke I9, the

links

22 and 23 and their cross 29 and 3U fpro vide toggle mechanism controlling the voperation of the

jaws

25 and 26. Y"Ihe rod I2 extends downwardly a predetermined distance and inV a position adjacent the

jaws

25 and 26, there being a tripper end or knob 33 formed on the lower'end of the rod I2.

When the plunger end I of the rod I2 is pressed downwardly, the rod I2 will move downwardly carrying with it the

links

29 and 30. The downward movement of the

links

29 and 30 spreads the

links

22 and 23 and consequently the jaws and 26 apart. 'Ihe jaws therefore, when spread apart, will assume the position shown in Fig. 3, permitting the neck 34 of a bottle 35 to be received between or positioned within the

jaws

25 and 26. 'Ihe downward movement of the rod I2 is such that the

links

29 and 30 will extend below their normal horizontal center line. AThis downward movement may be limited by ears 36 formed on the inner ends of the

links

29 and 30 and these ears are adaptedA to engage the shaft or rod I2. The neck of the bottle is inserted a predetermined distance within the

jaws

25 and 26 of the device to have a band 31 applied thereto.

Bands 31 are preferably made of hydrated regenerated cellulose and these bands are preferably shipped wet, that is, a plurality of bands are shipped in a containerl containing a fluid to keep the bands smooth and moist. When the bands are applied to articles they are applied in their wet or hydrated state, the bands tightly shrinking about the necks of the bottles when dehydrated. It is a relatively easy matter to apply a smooth set band about the neck of a bottle Where a revenue stamp or seal is not applied over the closure 38 of the bottle. However, in cases where a stamp or seal 39 is applied over the closure 38 of the bottle, it is quite diiioult as great care must be taken not to tear or mutilate the stamp or'seal. Therefore when stamps or seals are placed over bottles, great care must be exercised. It has been found convenient and practical, therefore, to use a tool or device of the type just described to apply the bands in position about the necks of bottles and over the seals. In many 4instances for certain products the seals are required by statute and they must not be mutilated.

In carrying out the invention a band 31 is placed over the jaws 25 and 2lil when the jaws are in the position shown in Fig. 1. The plunger end I5 is then pressed downwardly until the rod assumes the position shown in Fig. 3 at which time thelinks 29 and 301v will be beyond Y wheel 52.

lmove the links 29fand 30- above their normal horizontal center line.

In this latter position thefspring I6 pulls the rod upwardly and consequently draws. the

links

22 and 23 inwardly to the position shown in Fig. 4. The jaws25. and 26wil1 therefore engage the neck of the bottle as shown in Fig. 4.. To retract the jaws a pressure is exerted at the points indicated at 40, Fing. 5, to hold the band to the bottle while the jawsarejf-'being slipped out of position. After the jaws l'iavejrb'een removed, the bottle is permitted vto stand until the band dries after which vtimetlfie band will tightly shrink about the neck ofthe bottle .in the manner-'shown in Fig. 6. A neat appearanceis rendered to the bottle, the bottle is rendered ornamental, the seal or stamp is neatly and permanently positioned inplace and the cap 38 of the bottle is locked in place and vcannot be removed. If desired, the band 31 may be applied to the neck of the bottle before the stamp or seal 39 is applied. However, a much -neater and attractive looking package is obtained if the seal is applied to the bottle before the band is put in place.

In Figs. 7 to 9 inclusive there is shown continuously operatingapparatus for applying bands to bottles. In these views there is shown a support having a transverse axis or axle 5I upon which there is rotatably mounteda wheel 52.l A plurality of

jaws

25 and 26 extend outwardly radially from the outer peripheral surface of the These devices, which are mounted about the periphery of the wheeL may be exactly the same in construction .as the device shown in Figs. l to 6 except that instead of using a handle I6, the wheel 52 is employed. The rod I2 extends through the wheel with the plunger l5 on the inner sideas clearly shown in Figs. 7 and 8. Also, instead of manipulating each device manually to stretch the bands when they are applied over the

jaws

25 and 26, a rigidly mounted cam 53 may be mounted in a position to successively engage the ends I5 as the wheel 52 rotates. The wheel 52 is rotated by a motor 54, a chain 55 and reduction gearing 56.

In operation the bands 31 are successively applied onto the device by an operator standing at the left-hand side of the machine, these bands being placed on each device as it moves to applying position. During the rotative movement of the wheel, the bands 31 will be stretched when the end I5 of the rod I2 engages -the cam 53. The tension on the band on the

jaws

25 and 26 holds the

jaws

25 and 26 in their extended position. At the right-hand side of the machine, Fig. 7, an operator inserts'the bottle 35 between the

Vopen jaws

25 and 26, and in inserting the neck in position, the plunger end 33 is engaged by the bottle with sulcient force to move the rod I2 inwardly a predetermined distance at which time the spring I6 will move the jaws to closed position at which time the jaws, with respect to the band and bottle, willbe in exactly the same position as shown in Fig. 4. The operator handling the bottles therefore has nothl the bottle, while in Fig. 6, the bottle is shown as having the stamp or seal applied aboutv the smaller dimension of the bottle.

If desired, the spring means 60, Fig. 3, may be positioned relative the links 22 and 23' and their cooperating

links

29 and 30 to assist in-overcoming the urging action of the spring I6 to hold the -device in`its extended position, that is, the posi-- tion shown in Fig. 3 when the

links

29 and 30 will bemoved below their normal horizontal center lie.

The purpose of a band is to makelan air-tight seal on a bottle, as the band shrinks by dehydration. A cellulose band from its normal diameter is susceptible of between 20% and 25% shrinkage. Naturally the tightest band that will go on a bottle makes the best appearanceand best seal after the band has shrunk. The use of the mechanism herein described permits the use of the band actually Vsmaller normally than the bottle would require, as -the applicator stretches the band considerably and permits of easygapplication. When the applicator is withdrawn, the band does notv immediately spring back to its normal diameter as would rubber, but

upon dehydration does tend to seek its smallest normal diameter'dry.

The invention provides new and improved means for applying sealing bands rapidly and neatly in position o the necks'of bottles. The invention is positive and eflicient in operation, is strong and durable in construction, and can be readily and economically manufactured. The device can be operated manually as shown in Figs. 1 to 6 or the same device can be applied to a rotary wheel and tripped by a stationary cam. The invention however in either of its forms materially assists in the application of wet bands about the necks of bottles and prevents the revenue stamps or seals from becoming mutilated where such stamps or seals are required. l

Changes may be made in the form, lconstruction and arrangement of the parts of the ap paratus and vtheimethod may be varied within certain ldegrees without departing from the spirit of the invention-or sacrificing 'any of its advantages, and the right'is hereby reserved to 'make all such changes as fairly fall Within the scope, of the following claims.
