GEORGE E. (JOY, OF SYRACUSE, NEW YORK, ASSIGNOR OF FIVE-SIXTHS TO JOHN (JOY, SYLVESTER PIPER, AND ISAAC N. CHARLOOK, OF SAME PLACE.
COMPOUND T RESTRAIN THE SETTING OF PLASTER AND PROCESS OF MAKING THE SAME.
SPEGIFIGATION'forming part of Letters Patent No. 465,614, dated December 22, 1891.
Application filed September 2% 1891.
.To all whom it may concern.-
Be it known that I, GEORGE E. Cox, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and 5 useful Improvements in Compounds to Restrain the Setting of Plaster and Processes of Making the Same, of which the following is a full, clear, and exact description.
It is well known in the art that the setting of plaster used for architectural purposes can be retarded by mixing glue therewith, and various methods and means have been resorted to for the purpose of thoroughly incorporating the glue in the plaster, especially with the View of producing a retarding compound in a dry pulverulent condition. This has heretofore been usually accomplished by mixing a solution of glue with plaster-of-paris and in some instances with other ingredients, then drying or baking the mixture, and subsequently grinding the same into a pulverulent condition. This method of producing the retarding compound is obviously very slow and expensive and requires an extra mill or triturating machine.
The object of this invention is to provide a dry pulverous retarding compound which shall be adapted to be readily or thoroughly mixed with plaster-of-paris or other analogous cements in which the setting thereof is to be retarded and which retarder shall be simple and comparatively inexpensive in its manufacture; and to that end it consists in the following compound and method of producing the same.
The compound consists, essentially, of pul- Verous quicklime, glue, and flour, which I mix in the proportions of one pound of glue to twenty pounds of lime and three-fourths of a pound of flour. In mixing these ingredients I proceed as follows: I spread a layer of unslaked quicklime over a suitable floor to the thickness of three or four inches, then sprinkle said lime with sufficient water to slake it to a dry pulverous condition, and then, While the said lime is still Warm, incident to the slaking process, I sprinkle over it the glue dissolved in Water and thoroughly mix the mass by effectually stirring the same,
Serial No. 406,720. (No specimens) and then I sprinkle over this mass the Wheat or rye flour, and again stir the mass so as to thoroughly incorporate the flour. In this manner I obtain a dry pulverous compound which, when mixed with plaster-of-paris or analogous mineral cement and made plastic 5' 5 by the addition of water, will retard the set ting thereof suffieiently to enable the Workman to properly spread it in plastering the Walls and ceilings of buildings or in molding cornices or other ornamentations on the exterior or interior of buildings.
In preparing mortar for plastering buildings about twenty pounds of the described pulvero us retarder or restrainer is to be mixed with three hundred and fifty pounds of plaster-of-paris, and to this is to be added about ten hundred and fifty pounds of sand and seventy-five to one hundred pounds of lime, with a suitable quantity of Water to render the mass plastic and of a proper consistency to allow it to be easily spread by the trowel. This makes an excellent mortar for the first or scratch coat. For the second coat a smaller portion of sand should be used.
Having described my invention, What I claim as new, and desire to secure by Letters Patent, is
1. The composition of matter consisting of pulverous quicklime, glue, and flour, as set forth.
2. The method of compounding the withindescribed retarder, consisting in spreading a layer of unslakcd quicklime over a floor, then sprinkling said lime with sufficient Water to slake it to dry pulverous condition, and then, while still warm, due to the slaking process, sprinkling over the same a solution of glue and thoroughly mixing the mass, and then sprinkling over said mass and thoroughly mixing therewith a suitable quantity of flour, as set forth.
In testimony whereof I have hereunto signed my name this 23d day of Sepember,
GEORGE E. COY. n s] Witnesses H. M. SEAMANS, C. L. BENDIXON.
