CASTING noo'nss.
$PECIFICA'1ION formingpart of Letters Patent No. 703,171, dated June 24, 1902.
Application filed January 23,190 2.
To all whom it 77mg concern:
Be it known that I, FREDERICK BALDT', S12, a citizen of the United States, residing at Chester, in the county of Delaware, State of Pennsylvania, have invented a new and useful Improvement in a Casting Process, of
I which the following is a specification.
My invention consists of a casting process, and relates more especially to the introduction of the molding material into a receptacle containing a fusible pattern or of packing molding material or sand around'the said pattern.
In the art of casting when employing a fusible pattern said pattern is embedded in the molding material and is afterward heated to a molten state to allow it to run out from the mold that is formed through a suitable opening therein, after which the molten metal of which the article is to be cast is introduced into the space formerly occupied by the fusible pattern.
In casting by this process the fusible pattern is first placed within a box, flask, or casing, after which the sand is packed therearound; and my invention relates especially to the manner of introducing or packing the sand around the pattern, and the accompanying drawing illustrates one form of apparatus by means of which this process can be practiced.
4 In said drawing, A designates a tank or reservoir containing sand, which is provided with an outlet B, which'may be valve-controlled, if desired. Below this outlet B is a pipe or passage D, the upper end 0 of which is funnel-shaped. Situated over the funnel O is'a grate or sieve E, connected withthe device F for vibrating the same. The lower end of the passage D communicates with the transverse pipe or nozzle G, one end of which communicates with suitable apparatus, such as a fan, for creating an air blast or current therethrough, While the other endccommunicates with the flask or casing H,within which the pattern J or fusible material is to'be supported and afterward embedded.
The following is a convenientway of prac- 'ticing my process with the apparatus above Serial No. 90.867. (No specimnsJ' described. Sufficient sand is placed within the box or casing H to supporta pattern J. Then the outlet B isopened, thesieve or grate E vibrated, and an air-blast directed into the nozzleor pipe G The result is that the sand falls upon the vibratory grate E, is sifted therethrough, and falls through the funnel G and passage D into the nozzle'or .pipe G, wherein it is carried off by the air blast or current, being thereby introduced into the box or flask around the pattern and embeds the latter and is packed around the pattern. It is seen that in this manner I am enabled to pack the pattern in a highly efficient manner, obviating the slow and tedious methods now employed. It is understood, of course, that after the pattern is embedded it is melted by the application of heat and removed through suitable openings made in the sand,
tion of the blast of molding-sand, since the specific means I have set forth are merely to illustrate one practical way in which my process: can be-;practiced. For instance, it may be that the sand can be projected into the fiask' by centrifugalforce or, in fact, any other manner that would project it therein in a stream or blast.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is' 1-. Aprocess for casting, which consists in forming a fusible pattern, packing molding material therearound by projecting the same with sufficient force to pack'the material and form the mold, heating said pattern-to a molten state to remove the same, and lastly introducing molten metal into the space formerly occupied by the said pattern.
2. A process for casting which consists in forming a seamless mold byemploying a fugle receptacle out of contact with the walls thereof, packing the molding material around said pattern by projecting the said material into said receptacle with sufficient force to pack the material and form the mold, heating said pattern to a molten state to remove the,
same, and then introducing molten metal into the space formerly occupied by the said pat tern.
