application filed February 23, 1911. Serial No. 610,302.

To all whom it my concern:

Be it known that I, FnANgIs ALBERT Ponon'r, a citizen of the French Republic, and resident of Paris, France, have invented certain new and useful Improvements in Casting Machines for Siphon Heads, of I which the following is a specification.

My invention relates to casting machines for siphon heads in which the several parts, comprising mold parts and cores, are held in operative relation to each other in a mannet that certain of the cores maybe mechanically removed from a position coacting with mold parts in order to expedite the manufacture of, facilitate the removal of the finished product and automatically return the cores to a position in operative relation to the mold parts.

The objects of my invention are to make a complete casting with the least complicated mechanism, to provide a device simple in construction and operation, whereby its use reduces the cost of such castings, and to so dispose the several parts that they may be maintained at the desired temperature by a source of Heat such'as a blowpipe. I

arrangement of parts shown in the accompanying drawings, in which,-

Figure 1 is a central vertical section of a device embodying my invention, as seen from the side. Fig. 1 is a sectional detail of a portion of the base coreactuating mechanism. Fig. 2 is a central vertical section taken on the, line 22 of Fig.1, a fg mmetrical-portion to the right bein inicated by dotted lines. Fig. 3 is a etail sectional view through a portion of the clamping means for the mold parts.) Fig. 4 is a detail view showing the mechanism for imparting movement to certain ofthe core members.

Similar reference characters refer to similar arts throughout the several views.

The ap aratus comprises asuitably supported ta le 1, upon which mold parts 3 are symmetrically mounted and centered by means of the flange 1 formed on the table and serving as the bottom margin of the mold. These pattern plates 3 are movable and are operated by means of handles ,4.

a portion of the The inner hollows of the mold parts are formed complementary to shape the outer or exterior contour of the siphon head and the egress spout, and is in communication with a pouring gate 6 and the principal air pipe 7 through which the air escapes when the metal is being cast into the mold. A

certain number of smaller air channels 8 are also provided.

The core is composed of five parts. A central base core 9, serving to produce the inner hollow of the siphon head designed to embrace the bottle neck, has an end portion 10 corresponding to the shape of 'a valve seat. This core is provided with a concentric opening 12, extending from one ,-end to the other, communicating with a pipe 11, open to the air.

The base. core, through the pipe 11, is su ported by nuts 16 and is movable longitu nally by the forked lever 13, the pivot means 14 of which is carried by two supports 15 fixed to the underside of thetable 1. The forked end of the lever 13 embraces pipe 11 and is confined between adjustable nuts 16, in such .a manner that the base core is normally retained in a position in operative relation to the mold parts by the weight of the lever arm. The pipe 11 guided by a plate 11 which is secured to support 11 ma be separated therefrom whereby the taklng to pieces of the apparatus is greatly facilitated.

In order to form the central opening of the siphon head and lateral openings, I provide a core 18, having a pro ection 17 of a size to enter theupper portion of the opening 12 in the core 9, and which is arranged concentrically therewith. The core 18 is provided with an opening 19 through .which may be inserted a lateral core member'20 which serves to produce a lateral opening in the siphon head for the operating lever A curved core 24, the axis of which is concentric-with a pivot point 25, enters the complementary formed opening 2 of the mold parts 3' and serves to produce the inner bore of the siphon spout. The core 24 is guided through a confining plate 26 and is formed tapering toward the vertical axis of the siphon head. The core is secured, at its end 24*, to an arm 27 of an elbow lever 28 which is fork-shaped and pivot'ally mounted on the bearings 25 carried by the supports 25. This lever, owing to its weight, returns the core 24 to an operative position with respect to the mold parts.

A suitable blow pipe 29 is provided for heating the mold and for maintaining the same at' a temperature near the point of fusion of the material of which the siphon head is to be formed. This blow pipe heats the entire plate and more particularly the cores 9 and 24:, the core 18 being heated by its close proximity'with the melting furnace. The mold-parts rest upon the table by their own weight and are held in operative relation with each other b means of a clamp 30 having portions 30, ormed at ends, at

right angles to the main portion which is clamped together by a link 31 orthe like.

From the above description it is seen that the castsiphon head is inclosed by the mold parts, which being complementally formed allows the completed product to be removed without injury to the same.

The operation of the device is as follows :-After the table 1 has been made stationary at a suitable distance from the melt ing furnace, the table 1 and the cores 9 and 24 are heated by means ofthe blow pipe, while the mold parts are heated in a furnace. When the parts are perfectly clean and heated to the required temperature the mold parts are mounted on the table and the cores placed in their proper positions therewith. The molding metal enters the mold-' ing machine through the pouring gate 6. When the required amount of metal has entered the device the cores 23 and '20 are removed from the core 18, which permits the removal of the latter. Through the levers 13 and 28 the cores 9 and 24 are removed. This allows the mold parts to be separated, the formed siphon head remaining in one half thereof and removed therefrom by the operator to the finishin table.

The manipulation o the device very simple and requires but a short time to complete the cast siphon head and which enables the operatolarto' again assemble the device with very little loss of heat.

I claim-:- 1.
