DIST-EMPER-PAINT.

To all whom it may concern.- 1

Be it known that I, CHRISTOPHER G. DODGE, J r., formerly of the city, county, and

State of New York, but now of the city and county of Philadelphia, and State of Pennsylis a size formed by mixing glue or other similar soluble and adhesive material with water.

As heretofore commercially known, the calcimine or! distemper has been in the form of a cake or powder, having the glue, &c., neees- .sary for the size thoroughly incorporated with the pigment, and the whole beingin a drywon dition. In the preparation of these dry cakes and powders the materials are ground together, sometimes in a dry state or sometimes, and

more efl'ectually, in a wet or pasty condition.

When the wet process has been used it has heretofore been considered necessary-topress and ..t horoughly dry the mass, on account of theisnpposed impossibility of preserving the paint in a moist condition. When required for use water is added to convert the dry glue of the mixture into a size, and unless the water be hot much time is required for the softening and solution of the glue. Thus not only is theprocess of manufacture lengthened, but the product, in its hard and dry condition, cannot be rapidly dissolved under ordinary circumstances. 5 "-It is the object of my invention to furnish a calcimine or distemper which may be immediately reduced to the consistency required by the mere addition of cold water.

Ihave discovered that a calcimine having its binding agent in a pasty or moist state can be maintained in aproper condition for commercial purposes and without deterioration, or, in other words. that the pigments can be preserveddn combination with apasty or thick size in which the softening and solution of the glue has been completed, so that cold water will act upon it at once. I am thus enabled, when the wet process of manufacture is used, to arrest the same before the I pressing and drying, and thus expedite the ready-sized calcimine of moderate bulk in proper condition to be handled as an article of commerce.

vania-,.have invented a new and useful Im-- In this class of paints the binding-agent I use pariewhite, glue,- white soap, chloride 5 5' of calcium, car-bolicacid,'andwater, in the proportions hereinafter' specified.

In preparing the calcimine or distemper paints, Ita-ke three hundred and twenty pounds of paris-white, or its equivalent, and add to it a prepared sizing composed of six-v teen pounds of glue, sixteen ponndsof white soap, eight pounds of chloride'or' calcium, and

one hundred and sixty pounds of water,

These ingredients. are mixed and ground toigether until thoroughly intermingled, and to the mixture is;then added one-eighth of a pound of pure carbolic acid.

The mixture thus prepared forms a' calcimine, wall, or distemper paint of a consistency similar to white lead in oil, and is put up into packages of various siass for market, and is diluted with water when required for use.

The, effect of the soap and calcium salt is to produce a wall paint or calcimiue that will 7 5 work smooth under the brush; that will not peel, crack, or scale from the surface to which it maybe applied; that will not decompose,

putrefy, or grow oflensive in odor by standing, and will act as a disinfectantto the sur- 8o face to which it may be applied. a Oalcimine, wall, or distemper paint compounded in the manner hereinbefore described,
