FLUSHBOXES AUTOMATICALLY PRIMED SIPHON MECHANISM FOR Filed Feb. 25. 1954 2 Sheets-Shqec 2 liquid. When United States Patent'O" AUTOMATICALLY PRIME'D SIPHON MECHANISM FOR FLUSHB'OXES This invention relates to flushboxes andmore especially to the kind of apparatus which is fitted for automatic periodical' primingso as to eflect at predetermined intervals a flushing of pipe systems,.for instance for the flushing of containers or the mixing or measuring of liquids :of different ki -v a In the drawings affix ed to this specification and forming part thereof an embodiment of the invention is shown diagrammatically by way of example.

In the drawings:

Fig. l is a perspective view of the front wall cut away.

Fig. 2 is a vertical section, and

Figs. 3 to 7 are similar views illustrating various details of construction.

Referring to the drawings, 1 is a flushbox, 2 is its cover, 3 is a filling pipe in the cover and 4 is the flush pipe.

According to this invention, there is provided within the box 1 a siphon tube 5 of U-shape which in this embodiment is a flat pipe ending in a funnel 6 and carries a stop member 7. The siphon tube 5 is pivoted at 8 (Figs. 2 and 3) to a connecting pipe 8 which is mounted on the bottom plate of the box and into which the siphon tube 5 discharges. The entering cross-section of the pipe 8 is equal to its exhaust section and forms a connection 9 between the siphon tube 5 and the flush pipe 4.

The pivot connection between the siphon 5 and the pipe 8 is tightly sealed by a membrane 10 of flexible waterproof material which is fixed to the top part of the pipe 8 and pressed against, and fixed to, a plate 11 at the end of the siphon pipe 5. 12 is a counterweight fixed to this plate.

A characteristic feature of this device is the float body 14 mounted by means of pivot pins 13 on the intake end of the siphon tube. The lifting power of this body is greater than the force exerted by the weight of the siphon on the pins 13. The form and location of these pins is so chosen that the float, when empty, floats on the filled and surrounded by air, the float is in a state of unstable equilibrium causing it to pivot on the pins 13.

The air-filled float proper extending longitudinally of one side of the open float surface serves for keeping this surface above the level of the liquid when the body 14 is immersed. If necessary, more than one float may be arranged around the intake pipe of the siphon. A check 15 extending over the entire width of the box 1 limits the lifting movement of the device and determines the highest liquid level.

This device operates as follows. i

The box 1 is filled by a predetermined quantity of liquid streaming in which can move in as rapidly or slowly as desired, even in a drop by drop manner. While the box is empty, the different parts occupy the positions shown in Fig. 4. When the liquid level rises in the box, the float 15 is lifted and rocks the float body 14 which then assumes the position shown in Fig. 5. From that point on the lifting power of the body 14, which remains empty,

of the apparatus with part 2,847,022 .P at e nted Aug. 12, 1958 suffices for lifting the tube 5 and its'spivots on the member8 on thelexhaust .side. iWhile the liquid. levelrises further, the body 14 meets the checkl15' which arrests it (Fig. 6).- However, since the liquid level continues rising, the liquid issuing from 3 flushes the body 14:and removes itsi carrying power. Under the weight of the liquid which fillssthe, body 14, the combined 's'iphonS and body 14 are forced to submerge in the liquid and the box is now filledcompletely.

The siphon immersedjin the-liquidnowiprimes itself irremediably (Fig. :7) and theliquid. in the box flows,r as shown by the arrows,,,toward the. discharge pipe 4 -so.that

the box is rapidly emptied]Thebody 14,;which, when full, is in a state of unstable equilibrium when surrounded by air,,is emptied also entirelyand rocks back into: the position shown in Fig. 4. The apparatus has now-returned to its initial position, and since 'new liquid streams in continually, anew period of action beginsautomatically. It is the fixe check 15 which determines exactly the 1 liquid'level in he. hex 11- a Means may be provided for interrupting the functioning of the apparatus, for instance in the form of an arm 16 (Figs. 1 and 2) which can pivot on a shaft 17 mounted on a support 18 fixed on the cover 2 and carrying a hook 19 which extends into the interior of the box 1 and can engage a ring 20 on the tube 5. It is therefore easy to maintain the siphon in the elevated position where it serves as an overflow. In order to return the apparatus into working position, all that is needed is to disengage the hook 19 from the ring 20.

The new device distinguishes over similar devices hitherto known by being of simple design and still offering entire security of working. It is not exposed to getting dirty or to be worn out soon and does not present a mobile joint. It does not require attendance and functions precisely at any filling speed. It is fit to be used for all purposes and for smallest and greatest outputs.

By simply hanging up the siphon in its top position, it will serve as overflow until it is set free again and starts again working automatically. No priming by hand is required to start it functioning, no liquid seal is provided and its operation may be discontinued for any desired period of time. As soon as it is filled again, it will resume its automatic cycle of operations.

The two pivot members on the siphon tube and on the float, respectively, are not subject to excessive wear nor do they have any detrimental influence on the operation of the apparatus, because (1) the movement executed by the pivots is negligible, and (2) any play of the pivots would not in any way influence the operation.

Liquids charged with solid matter may be handled by the device as easily'as pure liquids without any danger of deposits forming so as to disturb the operation, because there is no conduit present excepting the siphon.

No failure can occur as long as the box is not damaged. If it should be damaged, the liquid level in the box cannot rise above the siphon which acts as an overflow, and the box can easily be emptied altogether by hanging up the siphon in top position until it is filled. After disengagement the siphon will at once start working again.

The ring which serves for hooking up the siphon, remains always free of the liquid and the release level always remains constant.

If it is desired to be able to throw the apparatus in and out by remote control, an electromagnet can be used which is set operating by means of a push-button, to set off as many flushings as required. With the aid of a clockwork mechanism the device can be timed at will.

If no electric current is available, a simple clockwork set for any predetermined moment can be used.

Any standard installation can be provided with the dcayiceiandsno particulariprecision of working is required. I -I11ci dcicescanibeifixedtiniplacetorttheibracket vcarrying the flush pipe and nothing but the liquid supply tube need be connected.
