JOHN LE MAY, OF INDIANAPOLIS, INDIANA.

'DISTRIBUTER FOR ROTARY CASTING APPARATUS.

To all whom it may concern y .Be it known that I, JOHN Ln MAY, a c1t1- zen of-the United States, residing at Into a plurality .of equi-distant dies.

The object of the invention is to distribute the metal equally to the several dies without splashing and splattering it which tends to chill it, thereby clogging the apparatus, and to cause chilled particles to enter the dies or molds in a manner to impair the quality of the product.

The object, also, is to eliminate the collection of the chilled metal on the surface of the distributer to a large extent, and to provide open conduits in the distributer which will be readily accessible for cleaning the chilled metal therefrom, should there be any, without removing a covering member or requiring the previous manipulation of any portion of the distributer.

- I accomplish the above and other objects which willhereinafter appear, by the means illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view and partial horizontal section of the distributor. Fig. 2, is a vertical section on the line 22 of Fig. 1 andFig. 3 is a perspective view.

Like characters of reference indicate likeparts throughout the several views of the drawings.

As is well known to those familiar with the centrifugal casting art, a series of dies or molds are mounted concentrically of and are rotated with a distributor, the latter being located at the center of rotation and pr0- viding the means through which molten .metal supplied to it is distributed and thrown into the-dies. This invention relates only to the construction ofsaid distributor, and, inasmuch as the associated parts are of common form, and well known, it is deemed unnecessary to illustrate the latter.

The distributer which I have selected for illustration has four discharge channels'diverging from the middle thereof and equidistant from each other, to serve a like number of or molds located opposite Patented Nov. 23, 1915.

Application filed April 13, 1915. Serial No. 21,029.

with four channels only byway of illustrationf suitable size and shape, depending upon the number of channels in it and the work to be done. It is provided with a spreader 5 at its center, here shown in the form of a cone which enters the discharge end of a funnel 6, shown in dotted lines in Fig. 2, through which the molten metal is delivered. Diverging from the base of the spreader are the channels 7, the inside walls 8, of which, are planes which are substantially straight and tangent to the base of-the spreader 5, except near their outer ends Where the portions 9 are bent forward to give a radial discharge to the metal issuing from the end of the channel. The upper portions of the inner wall 8 merge by curved lines into an overhanging top 10 which projects forward of the wall 8 sufficiently to restrain the metal from leaving the channel in that direction, 'but not to obstruct the removal of The body. 4, of the distributer is of any chilled or cold metal through the open front:

opposite the wall 8, merges into .a helicoid surface 12, which extends to the top cover of the next channelon that side. The surface 12 does not obstruct the entrance to the channel from which it springs, but leavesthe latter very open so the cold metal, during the, cleaning of the distributer, will come out easily and freely. 7

The channel as bounded by its upwardly sloping bottom and by the top 10 which slopes in the opposite direction, is outwardly tapering to concentrate the molten metal discharging through the channel and to direct. it with mouth of the die.

Theconstruction illustrated is preferable greater precision into the because the centrifugal action to discharge the molten metal is developed more quickly and is an appreciable force to turn the main quantity of metal as it passes the pocket'll.

While I have described my invention with more or less minuteness as regards details of construction and arrangement and as being embodied in. certain precise forms, I

do not desire to-be limited thereto unduly or any more than is pointed out in the claims. On the contrary I contemplate all proper changes in form, construction, and

arrangement, the omission of immaterial elements and the substitution of equivalents as circumstances may suggest or as necessity may render expedient.

I claimv -1. A rotatable distributer for a centrifugal casting apparatus having a plurality o conduits diverging from its center said conduits having longitudinal openings for v the ready removal of chilled metal therefrom.

I 2. A rotatable distributer for a centrifugal casting apparatus having a plurality of conduits diverging from its center said conduits being open toward the direction of rotation of the distributer for the ready removal of chilled metal therefrom.

. 3. A rotatable distributer for a centrif-- ugal casting apparatus comprising a. centrally located spreader and a plurality of conduits tangent to said spreader said conduits being open toward the direction of rotation of the distributer for theready "re moval ofchilled metal therefrom.

- 4. A rotatable distributer for a centrifugal casting apparatus-having a plurality 0 conduits diverging from its center said conduits being opentoward'the direction of rotation of the distributer for the ready removal, of chilled metal therefrom the outer ends of the conduits being bent forward of the major body-portions thereof.

a helicoid surface forming an opening to the conduit for the ready removal of chilled metal therefrom.

7. A rotatable distributer for a centrifugal casting apparatus comprisin a centrally located conical spreader an a plurality of conduits each having a substantially straight side tangent to the base of the conical spreader but bent forward near its discharge end, a bottom lowest at its inner end and merging with a gradual curve in the direction of rotation of the distributer into a helicoid surface to provide an opening to the conduit for the ready removal of chilled metal therefrom. In witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana,

this sixth day of April, A. D. one thousand nine hundred and fifteen. p
