This invention relates to machines for securing 'hoods of flexible and preferably transparent mav terial to the necks oi. milk bottles and the like by means of an adhesively coated tape wound circumferentially about the bottle neck. One object of the invention is to provide improved means for applying the tape around the neck of the bottle while the bottle is held stationary, in contrast to certain prior devices in which the bottle is rotated 10 while the tape applying device remains stationary, A further object is to provide an improved device for guiding and applying the tape to the hood. A further object is to provide improved devices-of this character which will be applicable to either 18 a hand operated or an automatic machine. Ad-

ditional objects will appear from the following description and claims.

Referring to the drawings, Fig. 1 is a side elevation of a bottle holding my machine embodying the invention;

Fig. 2 is an enlarged top plan view of the tape applying apparatus;

Fig. 3 is an enlarged sectional view of the hood ing and tape applying apparatus; 25 Fig. 4 is a perspective view oithe tape applying finger;

Figs. 5, 6, and '7 are diagrammatic views showing progressive stages in the application of the.

tape to the hood; and 30 Fig. 8 is a detail of the hooded bottle.

The machine is supported on a plurality of ver}:

tical members Ill carrying legs II. A table 12 is carried by the vertical members Ill just above the legs, and bears brackets l3 and M. The bracket 35 I3 serves as a bearing for a pair of spaced arms [5 and I6 having rearwardly extending projections l1 and I8 joined at their outer ends by a link l9. Fitted in the outer ends of the arms, and held as by a clamp screw 20; is a rod 2! bearing at its 40 upper end a support 22 for a milk bottle'23. A link 24 joins the lower arm IE to a lever 25 pivoted on the bracket l4 and having a treadle extension 26 by the depression of which the milk bottle support may be raised to carry the bottle 45 into the zonei-of operation of the'hooding and taping apparatus. Ifdesired, a spring Z'ljoins the extension 18 to an uppertable member 28 to assist gravityin'returning the bottle' support to its lowermost position; in which it is arrested by contact of the extension II with a stop 29 formed on the bracket l3. v

Supported by the upper table member is a hooding device which forms no part of my present 55 invention and which will therefore be described only briefly. This hooding device comprises a guide 30 into which a sheet of hooding material maybe introduced either manually or by some automatic device not here necessary'to be shown, and a pleating apparatus which drapes the sheet 5 of hood material downwardly around the neck of the bottle as the latter is elevated bythe linkage described. The latter device comprises four segmental rubber members 3|, each carried on a pivot 32, and divided at their inner peripheries I into fingers which drape and pleat the hood material .about the bottle neck as the bottle is elevated through them and which hold it during the taping operation later to be described. When the hooded and taped bottle is again lowered, the segmental members rock on their pivots to permit the bottle to pass downwardly without danger of the rubber fingers disturbing the freshly applied tape.

The tape applying apparatus is rotatably mounted in a bearing 35 clamped as by a screw 36 in the end of a bracket 31 arising from the table '28. Rot'atable within the bearing is a sleeve 38 prevented from moving upwardly within the bearing by an arm 39 pinned to the sleeve at 4,0, and

from moving downwardly by a handle 4| pinned to it at 42. Threaded through the sleeve 38, and held in adjusted position with respect to it by a lock nut 43, is a rod 44. The lower end of this rod is reduced in size as at 45, and bears upon this reduced portion a holder 46 having an interior 0 conical form so as to furnish a stabilizing support for the top of the bottle. The holder is secured to the rod as by a cotter pin 41, and is free to rotate relative to the rod; so that as the latter turns the holder may remain stationary upon the top of the stationary bottle. The arm 39 projects laterally so as to furnish supportfor a vertical shaft 50 upon which is fixed an upper'finger 5| and a lower applicator finger 52. A pin 53 on the upper finger is joined by a spring 5| to a lateral projection 55 of the arm 39, the spring being arranged substantially in line with the pivot shaft so as to hold the two fingers either in an outer position shownin Fig. 2,

in which the upper finger is held against further .45

outward motion by contact with a shoulder 56 on a the arm 39, or in an inner position in which the applicatorfinger 52 rests against the bottle neck, with a yielding pressure. The applicator finger is shown in perspective in Fig. 4, and in .its operation 50 in Figs. 5, 6 and 7. It is provided with a lateral notch 51 extending ,ina slanting direction and serving to receive a tape, and with a' recess 58" opening out of the notch on that side near the end of the finger and serving to guide the tape during 56 the application thereof to the hood. The end of the applicator finger is provided with a bearing the tape against the ofl fromthe guide 30 and carrying it upwardly through the circular ,series ofrubber fingers. This drapes the hood over the bottle top in somewhat the conditionshown in Fig. 3, and clamps the hood between the bottle top'and the holder 46. A length of tape t is now taken from any suitable source, its surface coated with adhesive or with asolvent for whatever adhesive coating there may be on it, in case the tape is not naturally adhesive, and one end placed within the slot 51 so as to enter the recess 58. The applicator finger is then moved so as to contact with the tape and carry it into firm contact with the hood on the bottle as in Fig. 6, preferably by pushing on the end of the upper finger 5| with the hand.

The applicator finger may now be carried around the bottle by rotating the sleeve .38 by means of the handle 4|. In this rotationthe tape remains within the recess 58, and is guided by it into accurate registration with the hood around the periphery of .the bottle neck. This part of the operation is indicated in Fig. 6. The tape'ispreferably chosen of such a length as to overlap upon itself as in Fig. 7, and whenits full length'has been applied to the hood the applicator finger, is once more removed from contact with the bottle by an outward pressure upon the upper finger 5|. Pressure on the treadie 26 is then removed,- and the bottle sinks through the rubber fingers which rotate as described above, to permit the bottle to move freely without danger of stripping the freshly applied hood.

1. In a bottle hooding machine having means for draping a hoodover the mouth and neck or a bottle, a guide rotatable about the bottle for guiding a length, of adhesive tape into contact with a hood so draped over the bottle, and a device rotating around the bottlefor pressing'the tape so guided directly against the hood and intoadherent contact therewith throughout its circuniference.

2. In a bottle hooding machine having means for draping a hood over the mouth and neck of abottle and holding the hood adjacent the bottom portion of the skirt thereof, a guide rotatable about the bottle in a plane above that portion of the hood which, is being held, said guide being adapted to guide a length of adhesive tape into contact with a hood so draped over the bottle,-

and a device rotatable around the bottle for presing the tape so guided directly against the hood and into, adherent contact therewith throughout its circumference.

8. In a machinefor securing a hood upon a bottle, an applicator finger having a tape receiving slot therein and a hood contacting surfac'e adapted to press the tape so guided into adhering contact with the hood on the bottle, the slot having a laterally ofl'set recessopening out of it'into which the tape may be received to preserve its alignment with respect to the contacting surface of the finger, means for moving said finger either 'into yielding contact with a hood on the bottle or into a position out of contact with the bottlefi ROBERT M.
