In order to insure. effective and satisfactory operation of a centrifugal separator, care must be taken to prevent the machine from being subjected to any shocks.

It has been proposed to eliminate shocks in a centrifugal separator by distributing the material to be centrifuged over the entire width of the centrifugal drum lor bowl in a uniform manner. Several forms of apparatus have been proposed for this purpose. For instance, one such apparatus comprises a, distributing pipe extending into the interior of the bowl, and having an opening extending lengthwise of said pipe and across the entire width of the bowl. By means of this arrangement, more material will pass through a portion of the opening nearest the feeding point, than will the portion of the opening on the outer end of the pipe. In order to eliminate this condition, it h'as been proposed to make this opening of variable width so that the opening diverges towards the outer end of .the pipe. However, I have found that lin apparatus of this kind, the opening hasa tendency to clog especially near the inner end of the pipe where the opening is narrowest.

One object of the present invention is to provide a new and improved device for uniformly distributing the material to be centrifuged in the inside of the centrifugal drum.

As an important feature of the present inve tion,- there is employed, for introducing the material, a distributing member having the outlet end thereof extending substantially over the entire width of the bowl and having a series ofV diverging channels receiving substantially equal amounts of material, and acting to uniformly distribute the material throughout the width of the outlet end.

In the accompanying drawing, there are shown for purposes of illustration, two embodiments of the presenty invention. Inthe drawing Fig. 1 is a vertical section taken through a centrifugal machine, and showing one form of distributing device embodying the present invention.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Fig. 3 is a front elevation ofanotherform of distributing device embodying the present invention, and

Fig. 4 is a section taken on line 4-4of Fig. 3.

The embodiments of the present invention are illustrated in connection with a centrifugal drum 10 mounted on a horizontal shaft 11 which may be driven from any suitable source of power. The material to be centrifuged is introduced through 14, 1932, Serial No. 605,153, and0 (ci. 21o-cs) a pipe 12 passing through an opening 13 at-one end of the drum 10, and leading into the interior of said drum. I have shown the end of the pipe 12 terminating substantially midway between the ends of the drum 10, and connected to the inlet end of a distributing member depending from said pipe. As ,an important feature of the invention, the distributing member has a pluralvity of fiared or diverging channels, the aggregate outlet ends of which extend substantially across the entire width of the drum 10.

- Inthe form shown in Figs. 1 and 2, the dis! tributing member comprises a fan shaped tubular member 14 subdivided by a plurality Aof diverging guide members or ribs 15 to form a Vseries of ad- 70 jacent channels 16 each tubular in shape. These channels are iiared towards the outlet end of the member 14 in'accordance with the are of said .member, and having substantially equal widths at their vinlet and outlet ends. It is advantageous 76 that the inletends of the channels 16 be spaced from the outlet end of the pipe 12 so as to leavel a manifold chamber 17 from which the material may be distributed equally to the various channels 16. By means of this distributing member, the so material which is delivered by the pipe 12 to the manifold chamber and then to the inlets of the various channels 16, is thereby uniformly! distributed across the entirewidth of the inside of the drum 10.

In Figs. Sand 4 is shown another form in which the distributing member is in the form of a fan shaped plate 18 connected to the outlet end of the pipe 12, and having connected thereto a series of guide webs 19 forming a plurality ofared chan- 90 nels 21'in the form of troughs through which the material is Auniformly distributed and delivered into the interior of the centrifugal drumllO. The plate 18 may form an integral part of the pipe 12 and extends therefrom in a direction to permit `95 gravitational flow of material thereover. l

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:-

1. A centrifugal machine including a rotatable 10 drum, a supply pipe therefor, and a distributing member in said drum, comprising a fan shaped tubular member having the smaller inlet end thereof connected to said pipe, and having the outlet end thereof extending over substantially 305 the entire width of the drum, said member being divided into a plurality of adjacent diverging tubular channels with the inlet ends thereof ad# jacent to the outlet end of said pipe, whereby the 'material supplied through said pipe is unito n@ distributed to said diverging channels, and delivered into the interior of the drum substantially uniformly along substantially the entire width of the drum'.

2. A -centrifugal machine including a rotatable drum, a supply pipe therefor, and a distributing member in said drum, comprising a fan shaped tubular member having the smaller inlet end thereof connected to said pipe, and having an elongated outlet end extending substantially across the entire width of the drum, and guide members in said tubular member dividing said tubular member into a plurality of adjacent tubular channels extending from a region close to -the inlet of said tubular member towards the outlet of said latter member, whereby the material supplied through said pipe is uniformly distributed to said channels and delivered into the interior of the drum substantially uniformly along substantially the entire width of the drum.

3. A centrifugal machine including a rotatable I drum, a pipe for conducting material to be treated i into the interior of said drum, and a member drum mounted on a horizontal axis, a supply pipe therefor, and a distributing member in said drum for uniformly distributing material substantially over the entire width of the drum. and comprising a fan shaped plate having the narrower end adapted to receive material from said pipe and the wider delivering end extending across substantially the entire width of said drum, said plate having a plurality of guide members forming therewith a plurality of adjacent diverging trough-like channels extending from a region close to said pipe towards the outer end of said plate, said plate extending in a direction to permit gravitational flow of the material from said pipe along said trough-like channels, whereby the material supplied through said pipe is uniformly distributed to said channels and delivered into the interior of the drum substantially uniformly along substantially the entire width of the drum.

5. A centrifugal machine including a rotatable drum, a pipe for conducting material to be treated into the interior of said drum, and a plurality of adjacent channels having their inlet ends close to the outlet end of said pipe for receiving material to be centrifuged from said pipe, said channels diverging at their outlet ends, and said outlet ends collectively extending along substaniially the entire length 'of the-drum, whereby the material supplied through said pipe is uniformly distributed to said diverging channels and delivered into the interior of the drum substantially uniformly along substantially the entire length thereof.
