VITREOUS FURNACE.
` invented certain new and useful Improveas is clearly indicated in the drawings, and
ments in Vitreous Furnaces, of which the following ,is a specilication. reference being had to the accompanying drawings.
This invention relates to furnaces and the like for the manufacture of vitreous compositions, and morev in particular to means for drawing olf the lsame in their molten state. Y
@ne of the objects of this invention is to provide means for a furnace which will permit molten material from the same to be drawn off in a clean stream, and without scum mixed therewith.'
Avfurther object is to provide such means with an arrangement for permitting it to be readily inserted into afurnace, and into molten material, and in such a way that the most desirable part of the material will tend to flow into the spout.
Another object is to provide such means, with end -portions which will be especially designed to prevent the ingress of undesirable material into the spout.
0th er objects will become apparent as the invention is more fully set forth.
ln the appended drawings which show a modification of this invention: Figure l is a perspective phantom view of an embodiment of this invention.- Fig. 2 is a longitudinal sectional view of the embodiment. Fig. 3 is a plan view of the embodiment, Figs. l and 5 are transverse sectional views.
Similar reference characters -refer to similar parts throughout the drawings.`
n the construction shown. the reference character 1 represents the wall of a furnace which is provided with an opening 2 for a spout 3. The spout is provided with a groove or channel 4 .near its upper portion this channel is preferably'rounded andrestricted at its bottom. The channel runs longitudinally through the spout or spout Specication of Letters Patent.

Application filed July 22, 1914. Serial No. 852,499.
block, as it may be termed, and runs through to one end, the drawing-off end, but stops some appreciable distance from the other or furnace end.
Apassage 5, transversely and downwardly extending through the block, connects the channel with the bottom of the block. The block is of suclrdimensions that its upper surface will be above the level of the molten material in the furnace. In this way the molten material can only flow out through the spout by following a path to the bottom of the block, thence up through the passage 5, thence along the channel 4 and out of the open end 6 of the same.
It will .be noted that only the cleaner molten material will go into the spout, the scum beingA prevented from doing so by reason of its being on the upper surface of the fluid, and the sludge being settled on the bottom of the furnace. -Thus the flow in the spout will be always clean and that taken out will be more satisfactory than without such an arrangement. The channel portion over the passage being in the furnace the fluid therein will be kept hot and with an veven pressure upon it.
While but one form of the invention is f shown in the drawing it is not desired to limit it to that particular form or in .any other Way otherwise than limited by the prior art, as many other constructions can 'be made without departing from the principles 4of this invention and coming Within the scope of the appended claim.
We claim:
ln combination with a furnace having'a rectangular opening, a rectangular prismatic spout block insertible in and filling the opening, said spout having a longitudinally grooved open duct in itsupper surface por-A tion and extending from the outer end of the block to a point away from the inner end of the block, said duct having its lower portion or depth arranged below the normal level of the material melted in the furnace,
and its'uppor and open portion above and accessible to inspection, a duct through the block extending from the inner end portion of the' groove duct toa point 'below the our signatures in the presence of two witscum line of the material in the' furnace, messes.
l said ducts being disposed' inthe block Where- HERMAN STAPELMANN.
by the flow of molten material through the y J ULIUS J UGH. 5 same 'may be controlled by moving thebloek Witnesses:
