"IMPROVEMENT lN'iTH'E MANUFACTURE OF INKSTANDS.

Specification forming part of Letters Patent No. 2,460,.dated'Februazy 21, 1842.

To, all whom it may concern:

BeitknownthatI,D.J.MANDELL,ofSpringfield, in the county of Hampden and State of Massachusetts, have invented a new and Improved Inkstan'd and I do hereby declare that the following is a full and exact description.

The nature of my invention consists in pro viding an inkstand in which water becomes expeditiously changed into a pure, beautiful, bright, and permanent ink, black, blue, or red, as the case may be, and flowing most readily from any pen, whether of steel or quill, while the outside is so constructed as to prevent the moisture tliatis within from oozing through, rendering the inkstand firm and cleanly without, while the interior moistens and wears gradually away beneath the action of the water.

To enable others skilled in the art to make and use myinvention, I will proceed to describe its construction and operation.

. I construct myinkstand in any ofthe known forms and apply thereto tops, lids, moldings, carvings, decorations, and other appendages of iukstands but in order to obviate the diffieulty of keeping ink in aform in which it may freeze and thus spoil, dry and thus waste, or spilland thus be lostand soil whatever it comes in contact with, and from other causes, I construct my inkstands as follows:

First, I prepare a dough of which to form the body of inkstands which I intend to make, whether for black, blue, or red ink.

The dough for black I thus prepare: I use Prussian blue or any other blue, first pulverizin g it, if necessary. If I use Prussian blue, and it be of a character to acquire blackness from extract of gall-nuts or gallic acid, I mix it with a decoction of gall-nuts (or something possessing the quality of gall-nutspand gumarabic. The proportion of extract of gall-nuts, or. of something possessing their quality in the decoction, must be such as will secure the neoessary degree of blackness to the Prussian blue, and the proportion of the gum-arabic Mixing the Prussian blue, as above described,

into a dough with the before-mentioned decoetion, I sometimes prefer to give it more body or a closer texture by adding lamp-black or any other substance as well suited for the office, and in such quantity as is necessary for the purpose, addingto the dough,in whatever case, enough of bullocks gall to impart a bitter taste; or, otherwise,where1happen to be using Prussian blue, which, on account of some peculiarity in its manufacture or from some other cause, the gallic acid will not affect, or where I am using some other blue, I give it blackness by mingling it with lamp-black or any other substance capable of answering the purpose, mixing the whole, it not with the decoction of gall-nuts and gum-arabic, with gum-arabic dissolved in water in sufficient proportion, as above described, adding, as in the former case. enough of the bullocks gall to give the dough a bitter taste.

The dough for the blue I thus prepare: I take Antwerp blue,'or any other blue that is sufficiently good and elegant, and havipg pulverized it, if necessary, I mix it with gumarabie dissolved in water in the same proportion as in the former case, sometimes varying the shade of the blue withsuitable proportions of whiting, or other material which would answer the same end, adding, as in the instance above mentioned, enough of bullocks gall to give the mass a bitter taste.

. The dough for the red ink I thus prepare: I take lake, vermillion, red lead, or some other good and substantial red, either singly or in such proportions together as will best secure the most desirable shade, shades, or color, and, having pulverized-them, mix them with gumarabic dissolved in water in essentially the same proportion as in the above-mentioned instances, adding, as in those instances provided, bullocks gall enough to give the whole a bitter taste.

Second. Havingin the manner thus described formed a dough for the bodyof the inkstands, I next press it into cases made of some metal, wood, glass, stone, or other substance, forming in the top a hole or holes, finishing all ofl" in the manner most ornamental or expedient, seeing always that the hole or holes are provided with a rim,either of metal or some other material, to a suitable depth and extent, and that the top becovered with metal, varnish, or anything else available as a suitable covering or finishing the hole or holes and top as above or, otherwise, I mold the dough into a suitable form and cover the sides and bottom with any composition cleanly, ornamental, and which will harden sufficiently to make a suitable outside, firm and water-proof, preparing The construction or manufacture of inkstands of the material and in the manner above described, which will change water expeditiously into an ink which will be not only of good color, substance, and permanency, but which will most freely flow upon almost any paper from almostany pen, whether steel or quill, while the inkstands themselves remain outwardly as firm and as clean to the touch to the last as any.
