BOTTLE-FILLIN G HEAD;

meogeee.

To all whom it may concern:

Be it known that I, SAMUEL Kara, a citizen of the United States, residing at Columbus, in county of Lowndes and State of Mississippi, have invented certain new and useful Improvements in BottleFilling Heads, of which the following is a specification.

My invention relates to an improvement in bottling machines, and more particularly to an improvement in bottle-filling heads for such machines; and this present invention is an improvement on the invention disclosed in application filed by me January 28, 1908, Serial No. 412,994; and also has to do with mechanism which cooperates with the cap finger set forth in a pending application Serial No. 77 8,714, filed July 12, 1913.

In the accompanying drawings Figure 1 is a view in side elevation of an improved head,

Fig. 2 is a vertical sectional view, v

Fig. 3 is a view corresponding to Fig. 2 with parts in elevation and portions broken away and showing the bottle projecting into the head and in the position of having the cap secured thereon.

Fig. 4 is a horizontal section on the line 4% of Fig. 2.

Figs. 5, 6, and 7 are horizontal sections on the line 5-5 of Fig. 2, showing the parts in different positions.

Fig. 8 is an enlarged vertical fragmentary seccpion of the lower end of the filling-head, an

Fig. 9 is a diagrammatic view illustrating the relation of parts of the bottling machine with respect to the filling head, which cooperate therewith to cause the automatic and synchronous action of theparts of my invention. a

A, represents the filling-head, which is, of course, only one of several in a completelyorganized machine. This filling-head is supported on a screw 1 which depends from a rod 2 from a point of support above on a circular track (not shown).

Within the head a receiving chamber '3 is formed. The size of this receiving chamber may be varied, and the elevation of the head on the screw 1 may be regulated to suit the requirements'of bottles of varying sizes by turning the screw 1 on thethreads of the rod 2 and within the head A. After this the lock-nut4 is screwed in place, compressing the packing gasket 5 in the seat ing or conical mouth 9,

by means of a strap 7, so that while the screw 1 is capable of being turned for raising and lowering the head to regulate the size of chamber 3, the filling-head A and rod 2 are held together against axial turning.

l/Vithin the lower end of the head, the throat 8 is stationed. This throat has a flar into which the cap C is forced by the cap-finger 10 from below, whereby the cap is held by the frictional engagement of its flaring edges against the wall of the throat.

In Fig. 2, the cap-finger is in the position of receding from the filling-head, just after having forced the cap G into the throat 8.

One of the primary objects of my present invention is to prevent the leakage and waste of the liquid to be bottled. This necessitates a tight joint between the bottleneck and the filling-head especially in the bottling of carbonated water or other effervescent liquids under pressure.

An elastic ring 12 is utilized for this purpose. This ring 12 is held at a point between the throat 8 and the mouth 11 of the filling-head, and through the orifice in the center of the elastic ring, the cap-finger and the bottle-neck pass alternately.

Means is provided for compressing the elastic ring 12 around the bottle-neck, which comprises the

compressors

13, 13, of which three are illustrated. These compressors are held slidably in the guide-cup 14 secured on the lower end of the filling-head A by screws or other means 15, 15. The

compressors

13, 13, move radially in this guidecup, they being provided on their lower surfaces with radial tongues 16, which fit and slide radially in the slots 17, in the bottom of the guide-cup 14. The outer surfaces 18 of the compressors 13 are correspondingly-curved eccentric to the center of the guide-cup in the form of cams and outside of each surface 18 is a groove 19.

A ring 21 is fitted and adapted to turn within the guide-cup 14. This ring is provided with as many depending lugs as there are compressors, and one lug is fitted to and adapted to traverse each. of the grooves 19,

V and to bear upon the corresponding cam surface of a compressor, so that as the ring 21 is turned in one direction or'theother,

the

lugs

20, 20, positively force the

compressors

13, 13, radially in or out, and, when inwardly, uniform pressure is applied upon the elastlc ring 12 is to resumeits normal proportions on the pressure or the compressors bemgremoved, yet 1t is well understood thatrubber sooner or later loses much of its elasticity, especially when strain uponit is al'l in one direction. This is largely, if not wholly, overcome by repeatedly forcing the cap-finger through the orifice in the center of the elastic ring and alternately with each outside compression of the ring, thus each time positively restoring the elastic ring to its normal proportions, in this way insuring and preserving the normal,proportions and dimensions of the elastic ring, thereby notonl-y' greatly arolongingits life but also getting the benefit of its highest efliciency during'its life.

An outer band lower end of the filling-head is secured to the ring 21 by studs 23, of which there are three shown in Fig. 5, these studs operating. through

elongated slots

24, 2 in the sides ofthe cup 147. g

The band 22 is provided with two arms 25 i and, 26 which extend out in more or less opdownwardly alongside the posite directions, one in position to strike one of the main posts 27 of the ma chine, and the other an obstruction 28 at predetermined intervals, one to turn the band 22 in a direction to compress the elastic ring .12 around the bottle-neck when the bottle is being filled, and the other to turn the band to releasethe ring before the head is lifted from the bottle.

t is understood, of course, that the bottlemouth is contracted around the neck of the bottle only when the bottle is being filled, and not when the capping or removal of the bottle takes place. 7 y i v v V The liquid to be bottled is supplied through a fixed pipe 29, j which extends lower end passing througha slot 3l in the band 22 into the head Aat'a point below the bottom of .chamberB. Through this hotlliq'uid discharges upwardly through the-nozzle 30,,

' raiser-p829 is provided eat a as, 32 V 22 titted toturn on the filling-head, the r which is normally closed by a spring ,3?

sleei edfuponthe'stem'of the valve. Ahead 33 on the end of this stem rests normallyin carbonatortnotshown) dischargesint'o the receiving chamber 3, and after '1 which the parts are returned to normal by an obstruction similar to post 27, not shown. v

Aii amount of liqui'l equal to the capacity of the bottle, being filled is discl'iarged through the pipe 29 as determined by the size of the chamber .3. The pressurein the so, I

chamber and bottle become equalized thy v communicating through outlets 41 in, the

lower end of the fillin'g h'ea'd A,. and the supply'of liquid tothe bottle is thus autoniatically stopped, the liquid passing down through the outlets l i nto the bottle, and the air displaced from the bottle rising into the displacement and receiving chamber 3 The displaced, air from the bottle prevents the, accumulatioi'i'of liquidiii the chamber 3.

lVhile the c'aibonator pressure isbeing maintained in the bottle, the cap is applied and secured to th bottle by Ftheb ad at the 7 month of the bottle being forced beneath the cap G intothe throats, the. tapering mouth 9 of which threat 8 thereb'y'clenches the ,crimped edge of the cap "around the beadedmouth of the bottle. 7

A rubber phig 38'. in thethroatB creates suflicientpressure on "the 'ca 0 to insure seating the cap properly, and as a result of its compression it forces the bottle free from the throat when the headilifts or rises from the bottle after the completion or, the capping operation. i 7

Valve 32 remains open until the arm 36 on the band 85 leaves the obstruction, where upon the spring 37 closes the valve 32; This is done previous to the filling-head being removed from the bottle, and, by manage-e the upturned nozzle seer the supply pipe 29, the lossof the liquid remaining in that portion of the pipe below the valye (after the valve is shut) which, would otherwise flow out is prevented, it being one of the primay objects o l my present invention, as pre viously stated, to prevent waste of any of t e liquid to be bottled as; well as leakage 1 a through thejoint formed around th e bottleneck. j Y
