UNITED STATES PATENT OFFICE.
JOHN LUCAS, OF BRIDGEPORT, CONNECTICUT.
COMPOSITION FOR CASTING-MOLDS.
No Drawing.
To all whom it may concern:
Be it known that I, JOHN LUCAS, a citi zen of Hungary, having declared my in tention to become a citizen of the United States of America, residing at Bridgeport, in the county of Fairfield and State of Con necticut, have invented certain new and useful Improvements in Composition for Casting-Molds, of which the following is a specification.
The primary object of the present invention is to provide a new composition of matter for casting molds in which the ma terial hereinafter disclosed, when mixed and combined in the quantities specified, produces a mold especially used in an iron flask mold that may be consecutively used a larger number of times for more castings and in case of slight damage, can easily be repaired.
With the above object in view and others that will appear as the nature of this new composition is disclosed, it is to be understood that slight variations of the quantities specified may be employed in compounding the material, but to obtain the best results, the proportions outlined should be employed.
The improved composition of matter includes the following ingredients in the proportions specified, to wit, 1% asbestos, 25% graphite, 2% horse manure, 17% core sand and 55% fire clay. The process employed in binding these ingredients consists in thoroughly mixing all of the proportions with the exception of the graphite binder Specification of Letters Patent.
Patented Apr. 27, 1920.
Application filed July 16, 1919. Serial No. 311,271.
which may be later graduall mixed therewith until all of the ingredlents are thoroughly combined and a substantially plastic mass results. With the material obtained by this mixture, and while in a plastic state, molds of any desired formation or design may be made and preferably iron flask molds and by suitable drying and baking processes, the mold is permitted to set and become hardened for the use intended.
While the above description alone refers to the molding of iron castings, generally known as gray iron castings, it is to be understood that the composition disclosed herein, is equally adaptable for molds for forming steel castings, brass, bronze, aluminum, and anything made in the foundry, and will function and perform, when made into a mold, in a like manner.
What I claim as new is 1. A composition for casting molds comprising the following ingredients in the proportion stated, to wit, asbestos 1%, graphite 25%, horse manure 2%, core sand 17%, and fire clay 55%.
2. A composition for casting molds comprising the following ingredients in the proportions stated, to wit: fire clay in excess of 50%; graphite, less than 50% of fire clay; core sand in excess of 50% of graphite; the least quantity of asbestos, and horse manure in excess of the asbestos.
In testimony whereof I affix my signature.
JOHN LUCAS. I
