6 Claims.

This invention in general relates to machines for casting metal used in the making of stereotype printing plates, and more particularly to improved simplified means for adapting a pump of the kind indicated, to deliver molten metal selectively from any one of a plurality of nozzles for appropriate use according to the type, size and shape of the mold in instant use.

Another object is to provide a novel multiple nozzle assembly adapted to be operatively applied to conventional stereotype casting pumps for permitting such a pump to be conveniently used for the casting of stereotype printing plates of the most diverse sizes and shapes.

A further object is the provision of a novel attachment for the spout of a metal casting pump adapting the said pump for use selectively with different sizes and shapes of molds.

Other objects and advantages in the design, construction, arrangement and adaptation of parts will appear more fully in the details hereinafter described and will be best understood when taking in connection with the accompanying drawing in which:

Figure 1 is a fragmentary elevational view of a casting machine to which an embodiment of my invention has been operatively applied;

Figure 2 is an enlarged elevational view, partly in section, with parts broken away, of a multiple nozzle assembly embodying my invention, detached from the spout of the conventional metal casting machine shown in Figure 1; and

Figure 3 is a transverse sectionalview taken on line 33 of Figure 2, looking in the direction of the arrow.

While I have illustrated a preferred form of the invention, it will be understood the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

In the drawing, H designates a casting pump of conventional design and construction to which a nozzle assembly A embodying my invention has been operatively applied. The casting pump includes the usual frame l2 and a furnace housing l3 in which a melting pot i4 is arranged. The melting pot as is provided with a pump cylinder i5 which is adapted to discharge molten metal into an outlet passage it connected thereto when an operating handle ll is manipulated in the usual manner.

The above details form no part of the present invention being common to metal casting pumps in general, but will sufiice to show how my device can be conveniently applied to conventional apparatus of the kind indicated.

The nozzle assembly A embodying my invention hereinafter described may be attached directly to 5, an extending portion Id of the spout 16 in any suitable manner or may include a pipe l 9 having a fiange 2i at one end which is bolted or otherwise suitably secured to a flange 22 formed on the exteriorly projecting part l8 of the spout l6. At h). the other end of the pipe l9, another flange 23 is provided on which latter a hollow nozzle-supporting' or spout member 24, forming a part of the nozzle assembly A, is detachably secured by the screw bolts 25. The member 24, as best shown in 15 Figure 2, is formed with an annular projecting portion or flange 2b, which is received in an annu lar groove or pocket 21, provided by an annular member 28, having an inwardly directed lip or fiange 29, and by a coacting rear surface or annu- .0 lar portion 3|, of a nozzle-bearing member 32 forming a part of my assembly A. The nozzlebearing member 32 is formed with a shouldered surface as at 39 which contacts with an inner surface formed on the member 24, the member 25 32 being secured to the latter and the member 28 in any suitable manner, as by the bolts 33, and is rotatably mounted on the inner or bearing surface 23 of the said member 2A, a considerable part of the body portion of which is arranged within a 30 bore 3 formed in the member 32. The member 32 is formed with or has secured thereto a plurality of nozzles, in the present instance two, 35, 33 of diiferent size and configuration, the bores 31, '38 respectively of which are of different capacity and shape and communicate with the bore.

By further inspection of Figure 2, it will be seen the bore of pipe [3 communicates with an opening 89 provided in member 2A, the member 24 being formed with an internal pocket 4i hav- 40 ing a shelving floor 42, and an outlet or spout 43. Adjacent the outlet 43, which communicates with opening 39, the member 2 is formed with apair of depending lips 44, which are adapted to extend into the nozzle in immediate use, which in the drawing is nozzle 36, and which serve as a guide for molten'metal when issuing from the outlet 43 into the nozzle being used, 'so' that the said molten'metal will not run into any interstices between the member 2 and the nozzlebearing member 32. The outlet 43 is formed by removing or cutting out a portion of the walls, as at 46, of the pocket 4!. Either of the

nozzles

35, 36 may be brought into use or co-operation with the outlet 43 by unscrewing the wing screw 41 which is threaded in a hole formed in the member 28 and engaged against the said annular flange 26, thereby permitting the annular member 28, which is fastened to the nozzle bearing member 32, to be turned by a handle or element 48 secured to a lug or extension 49 arranged on the body portion of member 32 for the pur pose of turning the

nozzles

35, 36 secured thereto. When the nozzle selected is in correct depending position and alignment with outlet 43, the wing screw 41 is tightened and the device is again ready for operation.

It will now be obvious that when the operating handle I! is manipulated, molten metal will be raised in the outlet passage I6 and conveyed into the pocket 4| through opening 39, thence passing through outlet 43 between and out of the lips 44, 45, into the bore 38, of nozzle 36 in instant use at a point below the level of the contacting surfaces of the

members

24 and 32, to be discharged thence into the customary molds, which may be done by means of the present invention through the nozzle best adapted for the purpose, by rotating the nozzle-bearing member 32 by handle 48 until the preferred nozzle is in the operative position shown in Figures 1 and 2. In practice, it has been found desirable to pour molten metal into stereotype molds from nozzles of different configurations and sizes, so that the most efficient application of molten metal to the said molds may be made, it being understood that in certain instances, it is preferable to have a wide flattened type of nozzle and again in other cases, a round nozzle may be an advantage. By inspection of Figure 2, it will be observed that the extremities of the lips 44, 45 of the nozzle-supporting member 24 are positioned substantially below the level of the inner or bearing surface 20 of the said member 24 so that molten metal will be prevented from finding its way into the joints or interstices between said nozzle assembly and the hollow nozzle supporting member. The entrance of molten metal into the bearing of the rotatable nozzle-supporting member, it is of course understood, would result in binding it when themetal cools. ing an adjustable nozzle assembly having a pair of nozzles, but if desirable other additional nozzles may be provided as a part of the assembly A.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
