Application filed October 5, 1923, Serial No. 666,758. Renewed April `1, 19517l rllhis invention relates to machines for tilling andcapping bottlesparticularly to power operated machines of the type wherelnrthe bottleis filled with carbonated water, with or without the addition of a Havering syrup,

nand capped by the machineimmediately after f The principal object ofthe present invention is "to provide 'a simple and efficient machineof this type wherein av plurality of bottles are simultaneously actedupon, one bottle 'being given its proper amount of syrup while the next preceding bottle is being lilled with the carbonated water and capped,1 the rais ing of the bottles being simultaneously performed by power driven means automatically timed toperi'ormgthe various operations in the proper sequence.

A furtherobject "of the present invention is the provlsionof means for lil-ling and capping a'bottle with a minimum otlabor on the part of the attendant, Vthe construction of the machine bein 0' such that the attendant is able to .control the operation of the machine -by a foot treadle so that `he mayfhave both hands ifi-ee for the handling of the bottles.

Still further objects of the present invention `reside in thespeciic details of several of the parts ol the machine as more particuu larly pointed `out inthe specilication followineand definitely recited in the claims.

The base l() is a substantially rectangular casing Aeaiclosing the .driving mechanism and supponting `at its upper end a column lfl which in turn supports the filler .head l2 and .the hopperlal .which discharges the sealing caps to the li-ller head lthrough the chute 15.

The base cover i7, secured to the base in any desired manner as bythe bolts 18,` encloses the lower "portion of the .bottle raising mechanism, .the parts visible in. Fig. 1 .being the .bottle helder1 19 which'is held against rot-a- `tion by the guide 2O on'lthe column l0 and :which maybe adjusted on the head 22 which vreciprocates a constant` distanceyby means .of

the .screw having a manually `operated anisin adapted to'be operated by the valve handle 29 to admit carbonated water under `pressure or `to permit of the shifting operation which is necessary in illing bottles with liquids having gas under pressure therein. The carbonated water or the liquidunder pressure issupplied througha rear fittingd 3,from anv suitable source of supplyyand its entrance into the filling chamber is norijnally preventedby a tubular valve 31 seating against the inner 'end ofthe valve casing or a suitable seat formed inthe valve head,` and if desired having an intermediate fiber waslier 321 valve being held against itsseat `by la 'spring 38. VThe valve is adapted to be brought away orflifted from its scat ,by the `head of a secondary ` valve plunger 3,4 which at `its outer end is connected with ,the valve end controlled by the `handle 29. /The plunger 34 is tubularand provided with connectedv ports 36 in lproigimity toitsends, the port near its innerextremity being. so located ythat when the plunger ispushed inwardly it will be openedtothe lilling 'chambem but whenfthe plunger is drawn bailruitil its whereby any snifting exhaust will be con-4 veyed down through that pipe and escape at an unobjectionable point. For preventing communication between the liquid inlet and the snifting exhaust the valve casing is provided with a front packing Vwasher 39 held to its seat and in position to engage the tubular portion or sleeve of the main valve by a transversely apertured long follower 40 yand the projection of the valve end 35 with which the plunger is connected is surrounded by a packing washer 4l which is held in place by a short follower and l'ock nut 42. The whole arrangement is such that when the valve handle is moved inrone direction or so as to draw the valve end outwardly, the main valve will be lifted from its seat and carbonated liquid allowed to enter the filling chamber, but upon moving the valve handle in the opposite direction, the main valve will be seated or allowed to remain on its seat andthe supplemental valve will be opened, putting the filling chamber into com- 'ini'inication with the exhaust through the two ports in the snifting valve plunger.

The filler head is provided with a pad for the attachment of a bracket 43 iny which the syruping device is mounted. This syrupiiig device comprises preliminarily a measuring cylinder44 which is vertically movable in the bracket but held against rotation therein, and within the cylinder there is a weighted f piston45, the upward` movement of which piston in the cylinder is limited by an accurate stop mechanism which is readily adjustable from the exterior so as to regulate the volume of syrup accommodated in the cylinder in any one charge. For admitting syrup to the cylinder, it is provided on the rear side -with a syrup supply fitting 46, Fig. 3, connected with anysuitable source of supply 'and having sufficient' hydrostatic head to elevate the piston. This syrup supply fitting `46 communicates with the interior of the cylinder through Van inlet port 47, Fig. 2,

'openingdownwardly, and adapted to beL closed at certain times, if so desired, byk a vertically movable valve 48. Vhen the valve is in the position shown in- Fig. 2 the inlet port 47 is in ropen communication through the intercommunicating passage 49 with the cylinder below the piston, and the entering syrup will raise the piston'to the limit permitted by the stop mechanism. The syrup is permitted to escape from the cylinder into the bott-le when the valve 48 is lifted by conlcoil spring 5l confined between the conical mouth piecev and a recess in a valve nut 52 screwing into the lower end of the cylinder. The stop mechanism for regulating the .volume of syrup measured, consists of a cylindrical gage nut 53 screwing into the upper end yof the cylinder and at its lower edge forming the stop for arresting the upward movement of the plunger or piston. The re llation of the pitch of the screw threads to the size of the cylinder is such that a com-v plete turn of the gage nut will vary the size of the measuring chamber to accommodate a delinite volume of liquidsay, for example, one-fourth ounce, and gage marks are provided on the nut for indicating each partic- Y ular rotation and the volume which will be measured at each point. In addition, the periphery of the nut and the cylinder with which it cooperates are divided into eight divisions, each of which indicates one thirtysecond of an ounce, and in order toretain the nut accurately and positively in its adjusted position with relation to the cylinder, vertical apertures are formed in the threaded portion of the two members, as shown at 54, in Fig. 3, for the accommodation of a locking pin55, thus providing for the most accurate adjustment and the retention of the parts `in their adjusted position with the greatest degree of certainty.

As a convenient construction the piston proper is preferably a relatively heavy body, as shown at 45, and this is surmounted by a leather packing 56 confined between the body v45 and a follower 57, the parts being held together by a screw-threaded handle 58 located within the cylinder and gage nut, as shown clearly in Fig. 2.

The weight of when the exit valve is opened by the engagement ofthe bottle mouth with the seat at the lower end of the valve, and by making the cylinder itself vertically movable in its bracket, any variation in the height of the bottle is readily accommodated and the only precaution necessary to observe is that the the piston effects the discharge of the measuredquantity of syrup ln other words. the weio'ht therewith as by the set screw 127. I iind it convenient to place a. wear sleeve 128 between the upper portion oli' the cover and the bottom of the skirt of the member 22 thus preventing `undue wear of the permanent parts of the machine. rier 19 be brought to rest before the end of vthe travel of the piston 123 the spring 125 will be compressed.

- It sometimes happens that the operator fouls a bottle against the bottom cap of the llerhead in which case the spring 125 is cornpressed to an excessive extent and unless some provision is made for such emergency the breaking of a bottle while the spring is under this extreme tension might damage the machine by the violence of its returnaction. To meet this emergency l Jform a dashpot at the end of the spindle 126 forming a cylindrical recess 130 connecting with the narrower portion of the spindle through the hole 133 and l close the bottom o' the cavity by means of a ball 1311 and fill the base 1() with lubricating oil up to the level of the small pet cock 135 shown in Fig. 1. Now when the piston 122% rises after the bottle carrier y19 and spindle 126 are brought to rest a vacuum is formed between the shoulder 127 of the vpistonand the larger diameter at the bottom of the spindle.

Oil is therefore drawn past lthe ball 12B-Lt and is discharged into the annular cavity between the piston and spindle through the radial passageway 138. Should a bottle break with the spring under extreme tension the spindle could not snap up into .contact with the piston without first discharging this oil, the discharge being regulated through a small hole (not shown) connecting the. annular chamber withthe base and restrictingy the speed ofreturn in exactly the same manner as in a door check.

c "little value in the ordinary operation of the `hub 97 rotates in the direction. shown by the arrow the engagement of the clutch head 108 with the timing ring 137 prevents engagement ot' the clutch pin with the immediate adjacent slot in the clutch hub but as the clutch hub continues to revolve in the direction shown engagement may be made with the vnext adjacent slot, the clutch pin then carrying the timing ring against the tension of the spring 139 until engagement of the clutch pin and clutch hubr is etfected.

The operation of the device is as follows: The attendant irst lls a bottle with syrup and transfers thisk bottle ttl the filler head As is obvious should the bottle car- While the dashpot action is of but' syruping device to the iilling device. When the syruped bottle is beneath thelller head the treadle 109 is depressed Araising the wedge 105and allowing the clutch pin to move rearwardly to lockthe cam hub to the constantly rotating clutchr hub 97. Movement or' the cam raises both bottles, the bottle beneath vthe filler head being raised from the position shown in Fig. 6 where it was placed by the operator to the position shown in Fig. 7 f

Just previous to the parts assuming the position shown in Fig. 5 the bottle cap holder 141 has discharged a cap through the chute and into position on the crown ring 7 3 .the opening inwhich is of such size as to readily permit exit of a crimped cap while barring passage ot' an uncrimped cap. rI he movement of the cam which causes the bottle to rise simultaneously lowers the throat 72 by means of the rod 140 which is pivoted to the lever 68 at its upper end and which carries the cam rollerV 120 at its lower end and then centers a cap 88 over the bottle 141 and also moves the next succeeding cap 142 back into the chute 15. A slight further movement of the roller 120 and rod 140 lowers the hollow cylinder and the throat member 72 into sealing contact with the crown ring forcing the valve cylinder 27 downward and reducing Vthe internal diameter of the sealing gasket compressing the gasket so that it forms a sealing engagement with the bottle. f

The operator now manipulates the handle 29 of the valve so as to irst admit carbonated water and when thel pressure is equalized movement of thevhandle in the opposite direction permits the escape of air the handle being continuously manipulated forwardly andbackwardly until the bottle is properly filled. At this timethe operator releases the treadle and since the two wedges are restored tonormal position the cam continues its rotation which was stopped by the withdrawal of the clutch pin 103 by the wedge 115. Further rotation of the cam thus set in motionrby release oi" the treadle forces the bottle up through the throat gasket and into contact with the sealing cap 88, the lirstV contact being caused by the plunger 60. As the bottle enters the contracting throat member 72 the plunger (SO is elevated against the spring 61 as shown in Fig. 6 and at this time and while the bottle yis still rising the cam raises the throat 72 to 4mains in that position while the hottie Contnues .its upward. movement and. then iesaid valve casing, a throat carried by saidV scends to a point wherek the top of the bottle is below the bottom of the cap port after which the throat 7 2 rises and the capped bot.

It will be noted from Figs. 4 to 7 that when the hollow cylinder 9.5 and throat 72 are in their lowest position the bottle carrier 19 has been raised less than half its travel and that between Figs. G and 7 the throat rises as the bottle rises but to a very much less extent. As shown in Fig 7 the bottle is at the extreme upper limit of its travel but the throat is midway of its travel having already risen to free the gasket from contact with the bottle neck.

What I claim is:

l. In a filler head, an axially movable valve casing, a sub-head movable with respect to sub-head and movable wit-hin said valve casing, means within said valve casing to form a seal with said throat, and means operable upon movement of said throat into sealing engagement to form a seal about the neck ot a bottle inserted within the liller head.

3. In a iller head, a hollow vertically movable sub-head, a throat secured thereto, a pivoted cap stop pivoted in the path of .said throat, and cooperating means on said cap stop and said throat :tor positioning said stop for centering a` bottle cap with respect to the axis of the liller head.

4. In a filler head, a hollow movable sub head, a throat secured thereto, a pivoted cap stop, and means on said throat for rocking said pivoted cap `stop"lior centering a bottle cap with respect to the axis of the filler head.

5. Ina filler head, a hollow movable subhead, a throat secured thereto, a pivoted cap stop adapted to have one end projected ben neat-h the throat, and means on said throat adapted to engage .the opposite end of the stop for rocking said stop on its pivotal center.
