Description
AUGUST r. manure-man, or rumour, NEW YORK, ASSIGNOR r0 CHARLES OALMAN AND UNITED STATES PATENT OFFICE.-
HENRY L. (JALMAN, PARTNERS DOING BUSINESS UNDER THE FIRM-NAME OF EMIL GAL- MAN & COMPANY, OF NEW YORK, N. Y.
I VABNISH AND PROCESS FOR PRODUCING SAME.
T 0 all whom it mag concern:
Be it known that'I AUGUST P. BJERRE- GAARD, a citizen of the United States, residing at Mineola, fassau county, New York, have invented certain new and useful Improvements in Varnish and Proc ss for Producing Same, of which thefollow-ir'ig isa full, I clear, and exact description.
This invention relates to improvements in varnishes.
Economy of production, the obtaining of an eiiective quick drying varnish, and the obtaining'of a dead or matt finish are among the objects and advantages of this invention. This varnish may be very advantageously employed for what is termed thefirst coat, for it will be found that the necessity of employing the usual filler may be avoided, although of course the varnish may be applied to a surface which has been previously treated with any of the well known fillers.-
In this respect the varnish possesses a unique advantage, for with the varnishes ordinarily employed a filler is usually required. By the use of this varnish it is unnecessary to rub the surface, but the finishing coats may be immediately applied as soon as the first coat of my improved varnish is dry. Another peculiar advantage of this varnish resides in the ease with which it may be Worked under the brush.
The varnish isprepared in the ,iollowing manner: The gum employed is called black damar. The solvent employed is benzin or other suitabie petroleum products benzol or its homologues, or mixtures of any or all of them; in other Words, a suitable liquid hydrocarbon. The process of preparation comprises dissolving the gum in substantially more of the solvent than is desired in the finished product, which solution is made at substantially ordinary tempera ture and pressure, then either settling or filtering out theundissolved impurities, and then removing (as by distillation) the surplus solvent until the mixture is of the deslred consistency. The object of using a surplus of the solvent in dissolving the gum is to secure a product that will settle or that may be filtered. This, however, is not the finished product, for as above indicated, to sei'irethe finished product requires that the excess of solvent shall be subtracted. It has been Specification of Letters Patent. Application filed January 14. 1907. Serial No. 352.104

Pate ted-Jan. as, 1908.
found heretofore that with that quantity of solvent required for a given amount of said gum to produce a varnish of the proper consistency for use, a product-will be obtained that Will not-settle and cannot be filtered on account of the slimy nature of the same. I
have found that an excess of the solvent in the first instance, these difficulties are removed, and a pro erlyrefined product is easily obtained. The surplus solvent after recovery can, of course, be used in making the next batch in lace of an equivalent quantity-of the original solvent. It will be observed that in the preparation no oil is required, but it should be understood that if I desire to add oil to the product it may be appearance, due not to any insoluble element but to the inherent quality of the gum. When applied and dried it will give a dead unique advantage of this varnish is that, unlike any other varnish not containing alcohol or a similar solvent, it dries with extreme rapidity, say ten minutes under favorable conditions, and never over a few hours under unfavorable circumstances. Unlike other so-called quick-drying varnishes, this varnish may be applied and Worked under the brush with the greatest ease; in fact, as. easily as any oil varnish. These properties give this varnish a particular value for use as a first coat, so-called.
One conspicuous and" Its dead or mat-t finish renders it unnecessary to rubor sandpaper the same to make it ready to receive another coat or coats. This is a distlnct advantage, because, asis Well .known,'when a coat of varnish is sandpapered or rubbed it is not only impaired but a substantial portion of the same is actually removed. By my invention't-his is entirely avoided the matt surface furnishing amos't 105 cfl'ecti-Ce anchorage for the superposed coat.
Mes-over, the labor (if rubbing down the" coat ofvarnish, as well as the time required to permit other first coat v'arnishesto is saved.
What I claim is: r 1. A varnish composed of so-called black.
damar guni dissolved in a suitable volatile,
liquid]hydrocarbon, from which varnish the impurities have been removed. j v I 2. A varnish composed of so-called black denier 11111 dissolved ina suiteblevoletile' liquid hydrocarbon, from which varnishthe nnpurltles have been removed, and a; suit"- a'ble quantity of oil.
3. T he process of manufacturing. varnis comprising dissolving a black denier gum in a, suitable volatile hydrocarbonsolvent at atmospheric pressure and temperature,
:the quantity of the. latter being in excess of that desired the finished product, then refining to remove insoluble impurities, and
finall distilling-to remove the e'xcess' 30 solvent. 1 v H AUGUsrRfBJERB-EoAARn- Witnesses:
