DEVICE FOR FILLING BOTTLES.

SPECIFICATION forming part of Letters Patent No. 768,837, dated August 30, 1904:.

Application filed February ll, 1904. Serial No. 193,036. (No model.)

To @ZZ whom it may concern:

Be it known that we, RALPH G/VRIGHT and KIRK K. IVRIGHT, residing at Buffalo, in the countyof Erie and State of New York, have invented certain new and useful Improvements in Devices for Filling Bottles,of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an apparatus for filling milk-bottles and other receptacles, and especially to the valves for such an apparatus.

The valve herein shown and described is an improvement on the valve described in our pending application, Serial No. 159,251, filed May 29, 1908, for an apparatus for filling bottles.

One of the objects of the present invention is to produce a valve which can be easily taken apart for cleaning' and will meet all sanitary requirements.

Another object is to produce a valve which can be cheaply constructed and easily and accurately operated.

Other objects will appear from the hereinafter description.v

vWe will now describe our invention indetail in connection with the accompanying' drawings, which clearly represent our 1nven` tion and which form a part of this specification.

Inthe accompanying drawings,Figure 1 is a vertical sectional view of one of our valves in its normal or closed position and connected to the bottom of atank to contain liquid with which bottles or other receptacles are to be filled. Fig. 2 shows the valve in side elevation disconnected from the tank. Fig. 3 is a vertical sectional View of a modified construction of the valve shown in its closed position and connected to the bottom of a tank. Fig'. 4: is avertical sectional view of said modified construction, showing the valve raised or in its open position. Fig. 5 is a perspective view of a detail.

The Isame parts in the several views are indicated by the same reference characters.

On the drawings the part marked 1 represents thc tank.

2 is an internal ly-screw-threaded bushing se- V cured in an opening in the bottom of the tank, by which the valve 3 is secured to the tank.

4 is a hollow plug screw-threaded to iit in the bushing 2. This plug is provided on its upper end with a valve-seat 5. A flange 6,

which is formed integral with the plug, rests against the under side of the tank. 7 is a downwardly-projecting collar, also formed on this plug.

8 is the opening in the plug, through whichy The lower end of this tube is provided With a screw-thread 13, which connects with the internally-serew-threaded portion 14 of another tube 15. These two tubes when connected together form a continuous channel, through which the liquid passes from the tank into the bottle when the puppet-valve 12 is raised off its seat 5. The tube 15 is enlarged at and above its screw-threaded portion 14:, so that when the tubes 9 and 15 are secured together a channel or passage-way 16 is left between the outer surface of the said tube 9 and the inner surface of the said tube 15.

17 represents openings in the tube 15 just above the screw-threads 14 or at the bottom of the channel 16, these openings and channel being the passage-way for the escape of air, foam, and overflow milk when a bottle is being filled. The tubel 15 is provided with a iiange 18 above the opening 17 and against which the washer or stopper 19 is fitted.

20 is a sleeve which surrounds and snugly lits over the upper end of the tube 15. The upper end of this sleeve tits around'the collar 7 of the plug 4, with its edge resting against the flange 6 of said plug. This sleeve is provided with a flange 21' near its upper end, against which the upper end of a coil-spring 22, which surrounds the sleeve and the tube 15, rests, the lower end of this spring resting against the flange 18. This sleeve is kept in IOO its normal position against the flange 6 by the coil-spring 22.

23 is an overflow-spout formed on the sleeve at or above the flange 21. This spout communicates with the channel 16 between the tubes 9 and 15. The upper end of the tube 15 telescoping with the sleeve 20, the ends of the coil-spring 22 resting against the flange 18 and the tube 15 and on the flange 21 on the sleeve 20, the spring tends to force the tube out of the sleeve and keeps the upper end of said sleeve seated in position around the collar 7 and against the flange 6 of the plug 4. and keeps the'valve 12 on its seat 5 on said plug, as is clearly seen from the drawings. As many of these valves as desired may be connected to the bottom of the tank, as illustrated in my application above referred to.

In operation the bottle to be filled is placed under the lower end of the valve-tube 15. The bottle is then raised so that the tube 15 projects into the bottle, with the mouth of the bottle resting against the washer 19, by which the mouth of the bottle is closed. As the bottle is further raised it raises the tube 15 against the action of the spring 22 and telescopes it in the sleeve 20, and as the tubes 9 and 15 are connected together the puppetvalve 12, carried by the tube 9, is raised off its seat 5, as shown in Fig. 1. and the liquid in the tanksuch as milk, for exampledflows through the opening 10 at the upper end of the tube 9 down through this tube and through the tube 15 into the bottle. As the mouth of the bottle is closed by the stopper 19 foam, air, and overflow milk pass out of the bottle through the openings 17 and through the channel 16, the air escaping at the spout 223 and the milk and foam passing over or through the spout into a receptacle, where it is collected. l/Vhen the bottle is filled, it is lowered, whereupon the spring 22 forces the tubes 9 and 15 to their normal position, and the puppet-valve is seated, and the supply of milk to the bottle is cut oil'.

In the modification shown in Figs. 3 and 11 we have formed the overflow-spout 23 on the upper end of the tube 15, and this spout of course moves with the tube, while in the valve shown by Fig. 2 the spout is-stationary. To permit this, we have provided the collar or sleeve 2O with a vertical slot 20E, through which the spout projects and in which it moves vertically. lVith this exception the operation of this modification is the same as the other construction above described.

In the construction shown in Figs. 1 and 2 the valve 12 is formed integral with a butterfly-nut 12, this nut and pin 11 being provided with left-hand scre\v.-threads, so that the valve may be removed from the tube 9 without liability of' the tubes 9 and 15 being separated, or the tube 15 may be removed from the tube 9 without removing the valve 12 from the tube 9, it being understood, of course, that the threads 13 and 111 on tubes 9 and 15 are righthanded. In the construction shown by 3 the valve 12 is held in place on the lefthanded screw-threaded pin by an ordinary nut 12b.. The valve maybe held on in any other well-known way.

To remove the whole valve from the tank without taking out the screw-threaded plug 4, the tube 15 is held in the hand, and the valve 12 is retrieved from the pin 11 by moving the the nuts 12fL or 12, when the tube 9 is pulled out of the plug et, carrying with it the sleeve 20 and spring 22. The tubes 9 and 15 may then be separated by screwing them at the joints 13 andll. When this is done, all the parts may be thoroughly washed and cleaned. It is to be noticed that as the openings 17 in the tube 15 are at the bottom of the channel 16 there is no pocket formed wherein milk would settle and collect. Then the tube 9 is removed from the tube 15, a brush may be pushed through the openings 17 and the ledge at the top of the screw-thread 14 thoroughly cleaned.

r1`he tube 15 and the collar or sleeve 18 may be removed without removing the tube 9. rlhis is done by holding the nut 12 or 12" so that the tube 9 will not turn. Then by turning or unsere-wing the tube 15 from the lower end of the tube 9 the spring 22 and sleeve 2O come off with the tube 15. These removed parts, as well as the lower end of the tube 9, may be washed and the parts then reassembled.

By our construction it is seen that there are no closed tubes, pockets, or recesses into which milk will collect and become stale and all the parts may be easily and quickly separated and when separated the tubes, sleeve, and spout and all of their parts may be easily, quickly, and thoroughly cleaned.

lVhile in describing the operation of our device we have stated that the bottle to be filled is raised to unseat the puppet-valve 12, it is of course understood that the bottle may be held stationary and the tank having our improved valve (or valves) secured to the bottom thereof lowered to the bottle, and when the stopper 19 comes in contact with the mouth of the bottle the parts will operate, as heretofore described, to open the valve 12, permitting the liquid in the tank to flow into and through the tubes 9 and 15 into the bottle and the air and overflow liquid to pass out through the openings 17 and the channel 16.

It is to be noticed that the spoutin the first form of our device remains stationary and near the bottom of the tank and in the modification, in which the spout moves, it is carried up near the bottom of the tank before the milk overflows. 1n both instances it is seen that the overii ow milk is discharged much higher than in the old forms of valves. This is quite advantageous, the bottles can be put farther down inthe filling-cases than could be done in the old forms of valves.
