Description
CROSS REFERENCE UNITED STATES PATEnT'orrIoE.
WILLIAM nosnnrs comma, or nunnnic ron, mast-w;
momma comrouma.
No Drawing.
To all whom it may concern.-
Be it known that I, WILLIAM R. CONARD, a. citizen of the'Unit/ed States, residing at Burlington, in the county of Burlington and State of New Jersey, have invented a new and useful Molding Compound, of which the following is a specification.
The object of the present invention is to provide a novel molding compound in which the ordinary foundry slag and hydraulic oe-= ment are employed.
In manufacturing the compound which constitutes the subject matter of the present invention, waste material from a foundry cupola or air furnace, commonly known as foundry sla is employed. The slag is commonly of a brous nature, andwhen it comes from the furnace in masses too large for immediate use, I comminute the slag by .crushin t grinding or otherwise, to a fine and pre ferably impalpable powder, although the fineness of the comminuted slag will depend upon the nature'of the casting which is to be produced.
The slag should be in a dry condition, and if it is moist, either before or after being comminuted, it may be dried, either before or after the comminutiug process takes place. The comminuted slag is then mixed with a hydraulic cement, either natural (Rosendale) or artificial (Portland) cement being employed, the cement, of course, being in a dry condition.- Ordinarily one part of cement and two parts of slag are employed, but considerable latitude may be permitted in the proportions of the ingredients. The
operator will be guided by the size of the] casting which is to be produced, and by other conditions which are known in the art. Ordinarily, if the castings which are to be produced, are of considerable dimensions, the amount of cement may be reduced, so as to securea more porous aggregate, whereby the gases generated in the casting operation may readily escape. After the conuninuted slag and cement have been mixed thoroughly, in
a dry condition, water or other liquid is added, in order to make the mass plastic. The plastic mass is thoroughly mixed until it is of a uniform and homogeneous nature. The aggregate in a moist and plastic condition, is applied to a. pattern, and in this con-.
nection itis to be understood that the word Specification of Letters Patent. Patented Feb. 18, 19131 Application filed August 6, 1812. Serial No. 713,890.
pattern is used to designate any element which serves to cause the molten-metal to conform to the shape of the object which'i's to be cast. After. the moistened aggregate has been applied to the pattern, the aggregate is worked into all of the interstices of the pattern, by rubbing, pressing or otherwise, so that all of the lines of the pattern are entered by the aggregate. If necessary, the aggregate applied to the pattern may be permitted to take an initial set or a final set, this step in the process depending largely upon the amount-of liquid which has been introduced into the aggregate. The pattern is then removed from the aggregate, the
same now conforming to the pattern, and
EXAMINER consummated either by permittin the mold to dry out in the atmosphere, or y the application of steam, or under the heat. of a fire.
The compound hereinbefore referred to, may be employed with equal propriety for making the drag, the cope or the core. ,A molding element, constructed as above described, may-be used repeatedly, and the employment of gaggers W111 be unnecessary.-
Molding elements constructed as above described, will be suitable for casting in a wide variety of metals, such as iron, bronze or brass, Babbitt, lead and the like, and by the use of the abovespecified compound, a casting will be produced which will be devoid of imperfections and which will be superficially smooth. Patterns of wood; metal or rubber,
depending upon-the nature of the work, may be coated as above described, and in carrying out the invention, the expense for material and labor will be reduced to aminimum.
-' Having thus described the invention, what is claimed is':-.
1. .A molding compound comprising comminuted foui dry slag and a binder.
2. A molding compound comprising comminuted, fibrous, foundry slag'and hydraulic cement. L
In testimony thatI claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
