This invention relates to the ?tting of caps to tubular containers such as those made of glass, this process being hereinafter referred to as “capsuling”. In the usual method of capsuling 5. glass vessels, more particularly those which serve for the accommodation of tablets, pills or the like, acap or capsule approximately ?tting the glass is arranged to slide ?rmly upon the latter by bending in or denting the ?ange portion of 10 said capsule. As such glass vessels are normally made ~from glass tubes, the diameters of which 18 invention is pressed axially by means of a plunger l2 so that the margin of the capsule I0 is con stricted by the hole H and is caused to ?t the tube 8 in a snug manner. This action can be assisted, if desired, by imparting simultaneously a rotating movement to the plunger l2. In Figure 1 said plunger is about to descend, and in Figure 2 it has eifected the constricting operation and is about to be raised forpermitting the removal of the capsuled container 8. 10 This principle is employed in the machine vary considerably, this capsuling is a tedious and - shown in Figures 3 and 4, which machine com time-wasting operation which has been hitherto prises a base plate 35 ?tted with a ?xed vertical carried out during the manufacture of‘ the con pin 36 carrying a body 31 capable'of angular tainers and prior to ?lling. _ movement. 'Within this body the plunger i2 is is It is the object of the present invention to pro slidably mounted‘, and is actuated by a lever l9 vide an improved method whereby these disad having a projection 38 which presses upon the vantages are overcome, since each individual cap upper end of the plunger l2 so as to permit rota is ?tted to its own tube either before or after the 20 ?lling operation, thus rendering it unnecessary to remove the cap until the contents of the con tainer are about to be used. , It is a further object of the invention to pro vide an improved form of apparatus for'e?'ecting 25 (Cl. 226-80) , the ‘capsuling operation, said. apparatus being simple in construction and comprising in theme ferred arrangement‘ means for receiving the'con tainer and capsule and for constricting the edge tion of the latter during the constricting opera tion. This movement is effected by the engage 20 'ment of a pin' 22 carried by a plunger H with a curved slot 23 formed in the body 31, downward movement of the vplunger l2 being regulated by a stop screw 20 co-operating with the lever H). For suitably holding the tubular container 8, the base plate 35 is provided with a set of jaws 25 l5, conveniently three in number, the upper parts M of which constitute a constricting member cor of the latter when an axial pressure is applied to ‘ responding to the ring 9 in Figure 1. The jaws l5 30 the head portion of said capsule conveniently by are actuated by vertical movement of a sleeve i6 means of a plunger. > ' It is a further object of the invention to pro vide an improved arrangement and construction of automatic apparatus whereby the capsuling 3 operation may be carried out continuously in as sociation, if desired, with means whereby the filled‘ and capsuled containers are labelled or '. otherwise marked. The invention is illustrated in the accompany 40 ing drawing in which _ Figures 1 and 2 are diagrammatic sectional ele vations showing the elements directly associated with the capsuling operation; ' , Figure 3 is a part sectional side elevation of a upon a ?xed supporting tube 24, this vertical 30 movement being effected by an oblique slot 26 in the tube i6 engaging a ?xed pin 25, rotation and hence vertical movement of the tube l6 be ing effected by angular movement of a radial handle 28 and being controlled by a helical spring I‘! tending to close the jaws l5; For limiting the extent to which the container 8 is inserted-into the jaws IS, a stop member 39 conveniently bear ing upon a compression spring is carried by a 40 central rod l8 mounted in a ?xed bracket 40. - In operation the body 31 is moved out of line . with the jaws l5, this movement being arrested by a stop‘platel‘l. When a container 8 having a loosely ?tting cap I0 is placed within the jaws Figure 4 is a plan corresponding to Figure 3; I 5, the handle 28 is released, thus allowing the 45 Figure 5 is a part sectional diagrammatic side spring II to close the jaws and the body 31 is elevation of an automatic type of ' capsuling moved into line. Depression of the handle l9 machine; I thereupon forces the plunger l2 into contact with Figure 6 is a diagrammatic plan corresponding the capsule l0. thereby constricting the lower 50 to Figure 5; and ' > ' margin of the latter until it grips the container 8 Figure 7 is a diagrammatic elevation of a fur ?rmly.v Upon release of the pressure upon the ther modi?ed form of machine arranged to oper lever IS the plunger l2 springs upwardly, and ate upon a plurality of containers simultaneously. after the chuck has been released by the handle Referring ?rst to Figures 1 and 2, a glass tube 28 the capsuled container-is removed. 55 I 55. indicated at 8 ‘is provided with a, loosely ?tting In ‘Figures 5 and 6, the improved principle is metal cap or capsule I0 and is ?rmly supported applied to a form of automatic machine having within a die 9 having a countersunk or other" four stations indicated at 1,, II, IiI and ‘IV in tapered hole II.

In a machine of. the class described, means for supporting a container, means for moving a cap axially of the container to close the open end thereof, means‘ for constricting said cap during rotated .by a geneva or equivalent mechanism indicated at 43 so that chuck members 44, four in number, stop progressively in register with each of the stations I, II, III and IV. The chuck members 44, which are similar in construction the axial movement thereof, and means for effect to the corresponding part of the mechanism shown in Figure 3, normally assume their closed ing relative rotation between the container and the cap during the constricting of the cap. condition, but are opened at stations IV and I by the engagement of the handle 28 with a cam 10 rail 45. The stop rods 18 are also mechanically 4.

A lateral arm 5| engaging a vertical recess in 20 the bracket 42 prevents rotation of the rod 29. tainer. formed of relatively movable sections adapted to In the operation of. the machine shown in Fig be moved into gripping engagement with a con tainer, a die section associated with each chuck ures 5 and. 6, a container and loosely ?tting-cap sule is fed by hand into each'chuck member as it reaches the station I. At due time as deter 25 mined by the Geneva mechanism 43 the capsule reaches station II where it is constricted by the plunger l2. ‘ 5. In a machine of the class described, a chuck 20 section, said movable sections being adapted when the chuck is closed to ?rmly grip the con 25 tainer adjacent the open end thereof, said die sections together forming a die having a bore tapering outwardly toward the open end of the container, and means for forcing a cap down wardly over the open end of. said container, the 30 tapering bore of the die acting to constrict the cap during‘ the movement of the cap axially of the container. 6. In a machine of the class described, a chuck comprising a plurality of relatively movable mem -35 After moving to station III, the container is labelled or stamped by any suitable mechanism (not shown), and as the chuck is 30 ?nally taken to station IV the jaws are opened and the ?nished container is ejected. In the modi?ed construction shown in Figure 7 an intermittently driven endless band 52 is pro vided with a series of sockets 53 into which the 35 containers 8 are fed by means of a plunger bers adapted to grip a container adjacent the mechanism indicated generally at 54. Capsules open end thereof to support the container during ID are then fitted to the containers, and as these pass beneatha pair of constricting plungers l2 a capping operation, means for moving said chuck and Ila, the latter automatically descend, thus to each of a plurality of stations, means for open 40 operating upon two . capsules simultaneously. The depth to which the containers 8 pass into the sockets 53 is determined by a guide or abutment. 55, the delivery end 56 of whichapproaches the curved part of the band so as to expel the ?nished 45 containers on to a delivery chute 48. _ The actual shape of the ring 9 or equivalen part for effecting the constriction of the cap sules can, of course, be varied to produce either a uniform constriction,‘ or alternatively a. corm gated or dented effect can be obtained. It is'not 50 essential for the constriction to be effected at the edge of the capsule, as it may also be made at any other part of the curved wall of the latter, either continuously or locally, as for example in 55 a number of sections. By forming the shaping portion 14 of the apparatus in a plurality of por tions adapted to accommodate themselves to the diameter of the container 8, a uniform constrict ing effect is obtained, even where the containers 60 vary in diameter to an excessive amount. What I claim is:-- ‘ i . 1. In a method of ?tting caps to containers, those steps which consist in placing the cap on the container, constricting the cap while it is in position on the container, and rotating the cap during the constricting operation. 2. In a method of ?tting caps on containers, those steps which consist in placing a cap on the container, constricting the marginal portion of the cap while it is in position on the container, 70 and rotating the cap during the constricting operation. ing said chuck at one of said stations to permit 40 insertion of a container therein, means for closing said chuck after insertion of the container there in, means at another of said stations for moving a cap axially of the container and into engagement with the same, means adjacent said opening means for forcing the capped container upwardly out of the chuck, and a de?ecting means for di recting the ejected container to a suitable dis charge point. 7. In a'machine of the class described, means 50 I snugly embracing a container adjacent the open end thereof for supporting the same, said means comprising a plurality of elements movable radi ally with respect to the container, each of said elements being provided with 'an arcuate portion 55 tapering outwardly toward the open end of the container, means for forcing a cap downwardly over the open endof said container, the tapering portions acting to constrict the cap during‘ the movement thereof axially of the container, and 60 means for rotating said cap forcing means during constriction of the cap. 8. In a method of ?tting bendable skirted me tallic caps over cylindrical glass containers, those steps which consist in placing the cap on the con tainer, bending the skirt of the cap to engage the wall of the container while the cap is on the con tainer, and rotating the cap during the bending operation to effect a complete circumferential en gagement oi the bent portion of the cap skirt with 70 the container.
