UNITED STATES PATENT OFFICE.
DAVID J. OGILVY, OF CINCINNATI. OHIO.
BINDER non cons-Maxine.
No Drawing.
To all whom it may concern:
Be it known that I, DAVID J. OGILVY, a
."citizen of the United States residing at the city'of Cincinnati, in Hamilton county and State of Ohio, have invented certain new and useful Improvements in Binders for Core-Making, of which the following is a specification.
The object of this invention is to roduce an economical and satisfactory core inding agent for use in foundry purposes. This object I attain by utilizing rosin pitch which being usually a secondar or byproduct 1s therefore low in rice. d his pitch ma be used for corebin ing either in a soli or liquefied condition. When it is used in a solid state it is preferable to have a pitch which is brittle and which may be easily powdered and which will-remain in a powdered condition under the ordinary weather conditions. A hard pitch suitable for inding if not athand may be produced rom a soft rosin pitch by removinga percentage of the more volatile products by heat, thereby I easily obtain a pitch of the necessary hardness. When it is referred to use the pitch in a liquefied condltion this is attained by liquefying with a high fire test crude or refined petroleum aided by heat, a mixture of say 40 parts rosin pitch and 60 parts petroleum being an average example. This results in a viscous liquid in which the rosin pitch is very finely divided insuring a thorough diffusion of the rosin pitch throughout the core mixture.
Specification of Letters ratent.
Application filed May 9, 1906. Serial No. 316,008.
Patented Mar. 4, 1913.
Among the many advantages of rosin pitch as a' core bindin agent are its low price,- the ease with w ich the hard pitch may be powdered and which may be kept in a powdered condition at ordinary temperatures, the facility of liquefying the itch in heavy petroleum and the stabillty o the resultin liquid. Rosin pitch has not the. disagreea 1e and irritating effect that many other corebindin agents have. Cores in which rosin pitc is used as the binding agent are not deliquesoent. By the term rosin pitch is understood the dark colored residues obtained by heating or distilling rosin or rosin mixtures, varying from a semifluid to a hard solid state depending on the tem erature and'duration of heating to which tl ie rosin or rosin products have been exposed.
What I claim as new and of my own invention and desire to secure by Letters Patent is BEISSUED 1. In a binder for core making, a composition of matter'consisting of brittle rosin pitch and a material suitable-for use in the making of cores, as set forth.
2. -Asa binder for. core making, a composition of matter consistin of powdered brittle rosin pitch and a pow ered material suitable for use in the making of cores, as set forth.
