Application filed February 6, 1911. Serial No. 606,737.

To all "whom. at may concern.-

Be it known that I, HENRY J. CHILTON, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Bottle-Handling Apparatus, of which the following is a specification.

This invention relates to improvements in bottle handling apparatus, and refers more particularly to a combined filling and capping machine of the rotary type.

Among the salient objects of the invention is to provide a construction in which the bottles are first filled in a suitable filling machine, preferably of the rotary type, and are then automatically conveyed to a capping machine, preferably of similar type, in which they are also automatically capped; to provide a construction which eliminates the necessity of any manual labor in conveying the bottles from the filling to the capping devices; to provide a construction in which the bottles are automatically arid successively moved in ahnement with the filling and capping devices by means of a traveling conveyer; .to provide in a construction of the character referred to means for supporting the bottles against lateral displacement during the operations of capping and filling, and at the same time affording a better contacting surface for the actu: atingplungers which raise and lower the bottles; and in general to provide an improved construction of the character referred to. e

The invention consists in the matters hereinafter described 'and more particularly pointed one in the appended claims.-

In the drawings--Figure 1 is a view partly in side elevation and partly in vertical section of my invention. Fig. 2- is a plan view of the same with certain parts shown in section. Fig. 3 is an enlarged sectional detail of a portion of the conveyer and bottle holding cups. Fig. i is a plan view of the same but showing a removable bushing within the cup. Y Fig.

is a vertical sectional view of Fig. 4.

In the drawings, C designates as a whole the filling machine and D the capping machine. The bottles are conveyed around each of these machines and delivered from the filling machine to the capping machine by means of an endless conveyor designated as a whole E. Upon the base frame ofthe machine is mounted a drive shaft 2, to the upper end of which 'is rigidly attached a main drive pulley 1 which is driven by any suitable source of power in the direction shown by the arrow 6. This shaft 2 is jou-rnaled in the bearing 3 carried by brackets 4 secured to the base 5 by means of bolts 4. The base 5 is mounted upon a suitable main base 6, as shown. The opposite end of the shaft 2 carries a pinion 7 meshing with a gear 8 secured by tap bolts 9 to the rotating standard 10 of the capping machine. The standard 10 of this frame is journaled in the upright stationary post 11 which extends through the standard 10. The lower part of the post 11 is provided with a horizontally extending flange 11' by which it is secured to the base 5 by means of bolts 12. The annular gear 8 in turn drives a shaft 14 through a pinion 13 carried by this shaft: The latter is journaled in bearings 15 and 18 carried respectively by brackets 16 and 19 mounted u on the base 6, and secured thereto by bolts 1'? and 20. U on the other end of the shaft 14 is mounte a pinion 21 which meshes with a similar pinion 22 carried by a parallel counter-shaft 23. One end of this shaft is journaled in a. bearing 24 formed in the bracket 19, while the opposite end of the I shaft is rotatably seated in a similar bearing 25 carried by the standard 26. The latter is secured to the base 6 by means of tap bolts 27. The right hand end of the shaft 23 is similarly provided with a bevel pinion 28 which drives a relatively large annular gear 29. This gear 29 is keyed by means of; a feather 31 to a hollow drive shaftwhich forms the main driving shaft of the filling mechanism. This drive shaft extends vertically through a stationary standard 34'. The latter forms the main supporting standard of the filling mecha- I11SII1 and is provided at its lower end with an enlarged base 33 whichrests upon the floor 6 of the machine. The lower end of the drive shaft 30 is rotatably seated in a bearing 32 secured to the standard 34' and at its upper end is similarly journaled in a bushing 34 secured to the upper end of the standard 34. To the upper end of the vertical shaft 30 is rigidly secured a plunger bracket 35 which rests upon a sleeve 35 carried by the upper end of the stationary standard 34., Thissleeve 35 is provided with a downwardly flaring extension 36 forming a support for bell-crank members hereinafter described.

The outer end of the bracket '35 is provided with a series of circumferentially exin their uppermost tending seats 37 in which are seated bushings 37 to receive the plungers 38 of the filling mechanism. Each of these plungers 38 is preferably hollow, as shown in Fig. 1, and is provided interiorly with a moi ably supported cap member 38, to which is pivotally connected, as shown at 40, arod 41. The lower end of this rod is pivotally con nected, as shown at 42, to a bell crank 43. The latter in turn is pivoted to the exten sion 36 of the sleeve 35 by means of pin 44. The upper end of each plunger 38 is closed, as shown at 38", and between the top 38 and the upper end of the cap 38 is inter posed a coiled expansion spring 39 whereby the cap 38 is yieldably supported. The opposite end of each bell-crank 43 is provided with a 'roller 45 which rides upon a cam track 46' carried by the bracket 46 mounted on a shoulder 46" upon theextension 33 of the main standard. This cam track 46 is so arranged that during a given periodv of ,the rotation of the filling machine the rollers "45 will ride upwardly and outwardly, ac-

tuating the corresponding bell-cranks and forcing the plungers 38 upwardly. The arrangement is such that as the plungers are forced'upwardly they will engage the bottle holders 48 hereinafter described and carry the bottles upwardly into engagement with the filling devices. These filling mechanisms may be of suitable construction,

and preferably comprise filling tubes 51,

centering mouth pieces 50. The mouth pieces 50 are telescopically mounted on the tubes 51 and operate a valve mechanism not shown, causing the liquid to escape through-the tubes while the bottles are held posit-ion. The roller 45,

as it rides off of the raised portion 47 of the cam track, lowers the plungers 38 back to their original position by means of the bellcranks, whereupon the bottles are automatically carried out of engagement -with the filling'meehanisms.

Referring more particularlyto F igs. 3 and 5, it will be noted that upon the lower end of each bottle holder 48 is formed a centering pin orstud 52, which is adapted to register with the opening 53in the top of the .plunger 38. The arrangement just described prevents the bottle Holders from lateral displacement-when-they are raised out of the conveyer cups 49. These conveyer cups 49 are open at either'end and of such shape as to accurately holdthe cups.

Preferably these cups themselves form the which forms the main frame support of the filling mechanism. This frame support 57' is carried by the rotary shaft 30. and rests upon the enlarged head portion forming part of the support 35. The outer ends of the arms 57 are provided with vertical extensions 57 which carry the tank 58. The filling mechanism is also provided with suitable valves 59 which form no part of the present invention. Liquid is supplied to the filling tank 58 through pipes 60 which are connected to a main supply pipe 62 through a T-connection 61. This main supply pipe 62 extends through the vertical shaft 30 and is connected to a horizontal supply pipe 64 by connection 63. This chain after beingtrained around the sprocket of the filling mechanism leads thence to a smaller sprocket 65 rigidly secured to the standard 66 which supports the capping mechanism.,...The lower end of this standard or post 66 is provided with a flange 67 bolted by means of bolts 68 to a head 69 upon the upper end of the rotary standard 10. To the enlarged head 69 of the rotary member 10 is rigidly secured in any suitable manner an annular series of sleeves or bushings '70. The lower end of the rotary standard 10 is provided with similar bushing 71 in alinement with the bushing 70. These bushings 70 and 71 serve as guides for the plungers 72. The latter are pref erably provided at either end with enlarged heads '73 a d 74 respectively, which fit closely within he respective bushings 70 and 71. The lower ends of the heads 74- are forkedas shown at 74 in which are journaled rollers 75 on pins 76. These rollers75 ride upon an annular cam track 77 formed on the flange 11 of the stationary post 11'.

, As the capping machine is rotated the cam rollers 75 will ride around this track and as they pass onto the raised portion 78 thereof, Will force the plungers 72 upwardly into engagement with the bottle holders 48. The

upper end 79 of the plunger 73 is recessed to receive the centering pins 52 of the bottle holders 48. After "eled over the raised portion of the track 77 they ride onto the downwardly sloping portion 81, thus carrying the plungers back to the rollers 75 have travtheir normal position and restoring the bottle holders to their seats in the conveyer. @These caps are fed to the cappers 80 through a chute 83 from a stationary hopper 82 in a :well known manner; This hopper 82 is held from rotary movement by a part of the frame not shown. The conveyer is centrally fsupported by means of a standard 84 secured by bolts 85 to the sub-base 6. On the upper portion of the standards 84 are rotat-ably mounted idler sprocket wheels 87 pivotally secured to pins 88 mounted in the standard the casting 57 84. The sprockets 89 of the sprocket wheels 87 engage the outer sides 90 of the cups 49 of the conveyer chain.

In 'Fig. 4 is shown in detail plan view one of the conveyor cups 49; each conveyer cup being provided with radially outstanding flanges 91, which in passing around the sprocket wheel 55 straddle the rib 92 thereon. At the right hand side of Fig. l these parts are shown in section, and in Fig. 2 in plan; the purpose of this construction being to hold the conveyor cups against vertical movement. The cups which form the links of the chain are provided with lugs 93, 93 which interfit with lugs 94 carried by the adjacent cup, these lugs being pivotally' secured by means ofbolts 95. Each cup is obviously provided with the spaced apart lugs 93, 93 and the interfitting lug 94. In order that the machine may be accommodated to bottles of various sizes, the bottle holders 48 may be provided with removable bushing 96 for smaller bottles. I

T he operation of the machine is apparent from the foregoing description and need not be described in detail. It will be noted, however, that the parts are so inter-connected that the filling andcapping devices are rotated synchronously with the bottle holding conveyer. The bottles are at all times maintained in proper centered position. a
