Application May 11', 1931.

Serial No. 536,470'

c claims. (ci. 226-77) This invention relates to improvements in bottle fillers and particularly to combined bottle fillers and cappers. l

In this connection attention isA directed to my copending application for patent, filed April 29,

1930, entitled Bottle llers and cappers and bearing Serial Number 448,224.

The principal object ofthe invention is to simplify vthe mode of operation'and the means for iilling ,l and capping bottles. n

Another object is to prevent leakage; at the filler between the bottle filling operations.

A further object is to provide an improved holding, clinching and crimping means for crown caps. l

Other objects and advantages will appear as the description progresses.

In this specification and the accompanying drawings the invention is disclosed in its preferred form. It is to be understood', however, that itis not limited to this form because it may be embodied inV other forms Ywithin the spirit of the claims following the description.

In the two sheets of drawings:

Fig. 1 is a vertical section of a combined iller and capper constructed in accordance with this invention.

Fig. 2 is a similar View of the same in the -tle lling position.

Fig. 3 is a similar view of thesame in tle capping position.

Fig. 4 is a similar view of a modified form of portable bottle ller in the closed position.

Fig. 5 is a similar View of the same in the bottle lling position.

Fig. 6 is a side elevation of the modiiied form complete with the handle and vent.

In detail the construction illustrated in the drawings, referring to Fig. 1, comprises the outer shell 1, having the chamfered opening 2 lat the bottom. Its upper portion or head 3 has the threadedcentral opening therethru to receive the threaded end 4 of the plunger of the capping machine. The interior opening of the shell has the annular shoulder 5 and is recessed at 6 and vented through the head at 'l to receive the nipple 8. The side of the shell is slotted at 9 to clear the the botfiller nipple 10. This shell 1 rises and falls withA the plunger stud 4 to cap the bottle X resting upon the base of the capping machine in the usual manner.

The iiller valve mechanism consists of an inverted elastic cup 11, of tough vulcanized rubber stock. The annular plug 12 of softer elastic 5 stock is inserted in the bottom of the cup 11 which it ts snugly and with which it' forms ahermetic bond. The parts 11-12 coact as a unit to form` the chamber 13. The valve seat 14 is formed in the bottom ofthe plug 12. The vvalve lfcooper-I ates with the seat 14 and has the tubular stem,

16, extending thru the top 17 of the cup 11,. which it engages between the ange l8--19. The elasticity of the walls and the top 16 of the cup 11 normally pullthe valve 15 snugly" against. the soft seat 14. The valve and stem 15-16 may be formed of non-corrosive metal, bakelite or any suitable material. Y Y

The hollow collapsible cushion 20 is'set vwithin the recess 6 and is provided withY alined perforations 21-22 communicatingwith the vent 7 and the tubular stem 16.

The annular ring 23 surrounds Athe plug 12 tof which it adheres and stops against `the shoulder 5.

The .bottle Xis placed in the capping `machine under the ,plunger 4 asin Fig. 2. Vi/hen the plunger descends, the ring 23Y engages theY tcp of the bottle which pushes the ring up to the stop shoulder 5. This raises the cup 11 until the end 19 of the stem 16 impinges on the cushion 20. The resistance of the cushion depresses and collapses the top 17 of the cup 1l. The completion of the upward movement of the ring 23 thus raises the seat 14 off the valve 15. As the plunger 4 rises the valve 14-15 closes as in Fig. 1.

The crown cap Y is placed on top of the bottle under the bottom 2 of the shell and the plunger 4 again forced down 'to clinch the cap onto the neck of the bottle, inthe usual manner. The presence of the cap carries the valve 15-16 upward, which compresses the cushion 20. The re"- sistance of the cushion is sufficient to depress or crimp the center of the cap Y, which further ccm- -presses the corl; gasket Z between the cap and the mouth of the bottle insuring perfect sealing of the bottle closure.`

This invention operates substantially as follows: The liquid flows thru the nipple 10 into the chamber 13 and is stopped by the valve 14-15 as in Fig. 1. If the liquid is siphoned, the flow can be started by applying suction to the vent nipple 6 after the bottle X is inserted in the machine. A Insertion of the bottle as in Fig. 2 opens the valve 14-15, permitting the liquid to ow into the bottle. The liquid is directed against the sides of the bottle clown which it flows, while the air impounded in the bottle flows upwardthru the tubular valve stem 16 and escapes at the vent 7. If foaming liquids are being handled they will OW into the bottle Without efervescing, if directed against the sides of the bottle as stated, and the impounded air is given a free outlet. If there is any mingling of such liquid with the outgoing air, regurgitation is set up and filling of the bottle is prevented.

When the pressure against the mouth of the bottle is removed the resilient Walls and top 17 of the cup 11 expand and draw the valve 15 against its seat 14. This seat being oi soft rubber it insures a perfect stopping of the liquid, even in the presence of ordinary obstructive solid particles suspended in the liquid, which cause an after drip at the filler when other forms of valves are used. The extended annulus of the valve at 24. of soft rubber seals the mouth of the bottle against overflow during the lling operation, see Fig. 2.

In addition to the mechanical effectiveness and simplicity of the resilient chamber 13 it protects the liquid from contact with the metal parts of the apparatus. All the parts contacting the liquid canbe of soft and hard rubber respectively' and easily maintained in a sanitiary condition. The modified form of this invention shown in Figs. 4-5-6 is similar in construction and mode of operation to that previously described, except that the capping mechanisms are omitted. For identication the various parts will be given the same reference characters previously used, with the addition of the character zv. This modification is especially useful for rapidly lling bottles arranged en masse. The handle 4J; is substituted for the plunger 4 through which the tubular vent 7a: extends and is bent laterally so that the hand of the operator will not close it. When the ring 23.1: is pressed down upon the neck of the bottle the Walls of the chamber 13 compress and open the valve 14m-15x. Lifting the handle 4.1; automatically closes the valve. The shell la: merely acts to guide the top of the bottle under the valve and to give stability to the device in operation.

Having thus described this invention what is claimed and desired to secure by Letters Patent is:

1. A filler including a shell having an internal shoulder, resilient walls within said shell forming a chamber and having a valve seat therein, a ring encircling said seat and adapted to engage said shoulder, a valve engaging said seat and having a hollow stem engaging said Walls.

2. A ller including a shell having a vent therefrom; a resilient Wall within said shell forming a chamber with a valve seat therein; a valve engaging said seat and having a hollow stem engaging said wall and said shell and communieating with said vent.

3. A ller including a' shell; a resilient wall within said shell forming a chamber with openings in its opposite sides respectively; a valve engaging one of said openings and having a stem iixed in the opposite opening and a cushion interposed between said shell and the end of said stem.

4. A filler including a shell with a top Vent and a side opening and having an internal shoulder; a wall within said shell forming a chamber havin openings in its opposite sides; a valve engaging one of said openings and having a hollow stem communicating with said vent and engaging the other opening, a cushion interposed between said stem and the top of said shell and a nipple eX- tending through a side opening and communicating with said chamber.

5. A llerkincluding a shell; a coinpressible wall, and a collapsible top within said shell forming a chamber with a valve seat therein; a valve engaging said seat and having a stem engaging said top and said shell.

6. A ller including a shell having a vent therefrom; a compressible Wall and a collapsible top within said shell forming a chamber with a valve seat therein; a valve engaging said seat and having a hollow stem engaging said top and said shell and communicating with said vent.
