IMPROVEMENT IN TREATING ASPHALT.
Specification forming pmt of Letters Patent No. 135,879, dated February 18, 1873.
. mineral matters by the addition of sulphuret ot' carbon, or of benzine and take from nine to twelve parts by weight of this purified' asphalt, and then add from eighty-tive to ninety parts by weight of powdered calcareous Vspa-raor marble, when the compound will be ready for use without any other addition.
The calcareous spar or marble to be used is first ground, and must then be sieved or washed to cleanit of all dust, leaving only a. line sand, with particles Vof about equal size.
The asphalt is purilied by means of an apparatus represented in the accompanying drawlng.
A kettle, A, is arranged, having double walls, so that steam, produced in a boiler, R, can be introduced into the annular space between the two walls for the purpose of heating and dissolving the asphalt and other ingredients placed into the same. This kettle is partly filled with the asphalt to be puriied together with sulphuret of carbon or benzine.
Above the asphalt a sieve, L, made of silk or wire gauze, is arranged, through which the dissolved materials have to pass, causing thereby the mineral impurities to fall back into the kettle. The solution passes then through a pipe, D, into a boiler, E, where the same is evaporated. The asphalt4 will remain in the boiler E, While the vapors of the sulphuret of carbon or of the benzine pass into the worin U, where the same are condensed, and the. liquid returned, through the pipe S, into the kettle A, to assist again in dissolving another quantity of asphalt. The pipe S enters the inner part of the kettle A near its bottom. The boiler E is inclosed in a casin g or jacket, into which steam is admitted, through the pipe H, from the steam-boilerR, whereby the dissolving liquids, such as sulphuret of carbon or benzine, are evaporated. At the same time an ordinary furnace, F, is arrangedA under this boilerE, so that those particles ofthe dissolving liquids which cannot be evaporated at the temperature of the steam can be evaporated by the direct heat of the furnace.
When the asphalt is dissolved by means of sulphuret of carbon some heavy mineral oil must be added to the asphalt, so that the required elasticity may. be obtained. The quantity of mineral oil necessary varies from two to live per cent., according to the nature and quality of the natural asphalt, and may be put either into the kettle Aor into the boiler E.
When benzine is used as the dissolving agent this addition of mineral oil is not required, as enough of the heavier parts of the benzine remains in the asphalt to obtain the desired elasticity.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. The arrangement of a sieve, L, in the kettle A above the material to be dissolved, substantially as and for the purpose hereinbefore set forth.
2. The combination of the kettle A, boiler E, and worm U, connected together in the manner andl for the purpose substantially as set forth.
3. The combination of asphalt, purilied of its mineral impurities, with the sand of calcareous spar or marble in the proportions and for the purpose substantially as described.
