PATENT OFFICE.

The present invention relates to a feed column for dentists who need recovery who allows gold, silver or platinum waste resulting from dental procedures. There are already canteens with collecting containers for valuable waste in the form of Fountain, d. H. those with water circulation to wash the bowl of the bowl and to take away the blood and the spit out masses. Allow these devices but it is very difficult to collect the valuable metal particles because these particles usually ends up in the collecting bin with unclean waste, and it would be required every time this waste is removed from the cuspidor ought to devote oneself to a boring and reluctant quest to find the aforementioned Separate particles that are usually very fine (filings and dust from external milling and polishing the seals, bridges, etc.).

These evils will now be eliminated by that in the bottom of the spittoon below a covering the contents of the spittoon Guard plate is a device for catching and washing cotton balls and other rubbish thrown in the spittoon is arranged, but which allows the valuable metal particles to pass through unhindered.

For this purpose there is a basket with a perforated bottom in the bottom of the bowl of the spittoon arranged, which is easily removed from the spittoon for the purpose of removing its contents can be.

In the drawing, the subject matter of the invention is shown in two exemplary embodiments.

Fig. Ι shows a vertical section through the feed column and

FIG. 2 shows a horizontal section along line AA in FIG. 1.

Fig. 3 shows the second embodiment of the flushing device of the spittoon.

As the drawing shows, the end of an arm a, which can be adjusted in height on a stand b , carries a part c, which has a channel d in the middle through which the water that has entered the spittoon flows off, and the on a lead e is connected. The upper end of part c forms a cylindrical housing f, in which a container g is mounted, in the center of which a tube h is soldered, the lower part of which engages slightly into the channel d in order to secure the guidance of the water and to close it prevent from rising up between the housing f and the container g. A leather washer i, which is clamped between the container g and the bottom of the housing f , also prevents the water from penetrating.

The lower cylindrical part of a bowl / without a bottom is accommodated in the container g. This bowl expands at its upper part and is conveniently made of glass or porcelain.

Since this interlocking always offers a certain amount of play, the shell / is secured on its upper part by a metal ring k in order to prevent it from tipping over due to an impact

ίο held, which is pressed to form a rim and is equipped with a fork I which comprises a conduit m through which water passes to a tap m ¹ , which is used to fill the glass for the mouthwash. A rotatable bolt I ¹ closes the fork / and prevents it from moving away from the line m and at the same time enables the tray j to be removed very quickly.

The shell / can also be made of metal.

In this case, the metal ring k is omitted, the fork I being soldered directly to the shell.

Inside the bowl / is an annular basket η , the bottom n ^{1 of which is} perforated and is kept at a distance of a few millimeters from the bottom of the container g in order to keep a space free in which the metal particles carried along by the water can be stored .

The middle wall of the basket consists of a sleeve n ² , which has large holes n ³ through which the water escapes to drain through the channel d.

The holes n ^a are seen high enough so that some water always remains at the bottom of the spittoon. A wire screen 0 surrounds the sleeve n ² and prevents the fixed parts from being carried away as soon as the water level rises above the sleeve n ^2.

A vertical tube p is fixed in the middle of the device by means of a part q which engages in the channel d and has lateral recesses q ¹ (Fig. 2) for the passage of the water coming from the bowl.

This part q is itself provided with a channel connecting the pipe p to a connector r connected to the line m and carrying a cock r ¹ activated by a handle r ² .

A sleeve s is pushed onto the upper end of the pipe p with strong friction and carries a shower s ¹ provided with small holes. The sleeve s is provided with a thread on the outside, onto which a conical protective plate t is screwed in a known manner, which covers the bottom of the spittoon.

By screwing the protective plate t on the sleeve s , it can be raised or lowered so that the width of the gap t ¹ between the lower edge of the protective plate and the shell / can be changed.

If you want to use the feed column, the tap r ^{1 is opened} by moving the handle r ² . The water of the line m then rises in the pipe p and sprays through the holes of the shower s ¹ and thus forms an umbrella-shaped water jet that washes the walls of the shell / and the protective plate p and the solid masses through the annular gap t ¹ after Basket η entrains, where a whirling occurs which stirs the solid waste and separates the metal particles from the same, the metal particles then falling through the holes in the bottom n ¹ into the container g.

As soon as the water exceeds the height of the holes n ³ , it overflows into the tube h and flows through the recesses q ¹ (FIG. 2) into the discharge line e.

Due to the large drainage openings for the water, no blockages can occur.

To clean the cuspidor, it is sufficient to remove the sleeve s with the protective plate t and to remove the metal sieve 0 and the basket η and to dispose of the waste contained in the latter. From time to time, when the gold or platinum particles that have been collected in the container g are to be removed, the latch I ^{1 is} opened so that the bowl j can be removed and the container g can be taken out.

As can be seen, it can be disassembled and reassembled in a matter of seconds as all parts simply interlock.

Fig. 3 shows the arrangement of a shower, the regulation of the falling on the shell Allows water jet.

This shower consists of a chamber s ² which is soldered at its lower end to a disk s ^{3 of} a sleeve s which is pushed onto the pipe p with strong friction.

Inside the chamber s ² , a disk s ^{4 is} soldered, which has holes for the passage of water and ^{carries an internally threaded sleeve s 6} , in which a screw spindle s ^{6 can be} screwed, which on its upper part with a rimmed head s ^{7 is} provided.

By screwing the screw spindle s ⁶ into the sleeve s ^B to a greater or lesser extent, the water jet that ^{emerges between the head s 7} and the upper part of the chamber s ^{2 is more or less throttled.}

You can regulate the water jet in this way in such a way that the bowl / in a suitable Way is cleaned.

Small, soil s ^a chamber provided holes allow small water jets

step out facing downwards and flush the protective plate t.

Claims (3)

Patent Claims: i. Feeding column with collecting container for valuable waste, characterized in that a removable ring-shaped basket (η) with a perforated base is arranged in the full-bottomed tray that holds all the waste, so that a space for collecting the valuable waste remains between the bases of both containers, while in the inner cylindrical wall (n ² ) of the basket furnace openings (n ^a ) are provided at a certain height, through which the rinsing liquid, which stirs the waste, runs off. 2. Feed column according to claim 1, characterized in that a vertical sieve tube (0) surrounding its inner annular wall is arranged in the basket, which prevents the floating waste from clogging the openings (n ³ ) of the wall (n ² ). ■ 3. Feeding column according to claim 1 and 2, characterized in that the known conical, serving to cover the bottom of the Speinapfes guard plate (t) is arranged by means of thread on the seated with high friction on the end of the water supply pipe sleeve of the shower, so that one can change its height by turning the protective plate on this sleeve. 1 sheet of drawings.
