LEA THEF! AND PRQOESS OF MANUFACTURING THE SAME Patented Sept. 18, 1806.
Application filed April 26, 1904. Serial No. 204,749-
. 1'0 all whom it may concern.-
- flexible material.
and have besides the serious Be it known that I, BRUNO TRENCKMANN, manufacturer, a subject of the German Emporor, residing at 25 Hauptstrasse, in the city of Schoneberg, near Berlin; Germany, have invented new and useful Improvements in Leather and Processes of Manufacturing the Same, of which the following is a specification. 1
This inven tion relates to a new leather that is distinguished by its fineness, suppleness,
lightness, and durability. Leather having such properties is required for many industrial purposes, and particularly for linin organ-pipes' and in the manufacture of be] ows or the like, and generally for purposes where it is desired to have an air-tight, light, and The leather hitherto used for such purposes was usually not absolutely air-tight or sufficiently flexible, while rubber sheets or fabrics impregnated with a solution of rubber, although air-tight, are very difficult to fit snugly by reason of lack of softness drawback of being liable to deteriorate and lose their flexibility, thereby becoming brittle under the influence of cold. This is of great importance in the case of organs in churches which are not heated during the Winter; The new leather obviates all these drawbacks and is therefore suitable for various purled-and used as the so-called gold heaters skin. It has been proposed to subject the skin of the blind gut to a tanning process; but the leather obtained in that way alone is not sufficiently air-tight and durable for such purposes as have been referred to above.
According to this invention the blind-gut skin, well cleaned and washed with potash or the like, is first tanned by means of mineral substances, such as chrome alum, &c., or with vegetable substances. In practice I have found that for two hundred skins of the maximum size four hundred fate. with ten liters of water is suitable as a tanning solution, or about the same amount grams zinc sulof chrome alum may be used. Then the skin is placed in a filling-bath of yolks of eggs, flour,- or the like, permitted to remain until thoroughl impregnated, whereby the skin is rendere thicker and stronger. This bath is preferably made by adding to about one liter of yolk of eggs a small quantity of flour. By this filling process the skins absorb the oil of the eggs. After havin rinsed the skin it is stretched and dried. T 's drying is effected by placing two skins one on top of another and allowing them to dry together in intimate contact. ing process the skins firmly adhere to each other without any luing or cementing material being used. he best plan is to place the grain or outermost sides of the two skins against each other; 7 may be superposed in which case the similar sides are placed in apposition.
When a multiple skin treated in the above described manner has become sufficiently dry, it is degreased or deprived of its fat by treating it with benzin. The skins are then "at the same time rubbed and kneaded in the benzin, whereby they are rendered exceedingly soft and supple. This treatment is necessary to remove the oil incorporated in the skin by the treatment with the eggs and to render the leather soft, pliable, and capable of cementing to wood and the like.
' The new leather has the property of being suitable for gluing or piecing together, so that large pieces of any size maybe made from small pieces, and the leather can be ce niented to other materials, such as wood or the like, which is of great importance for organ-pipes and the like.
My preferred process, as above stated, includes the step of tanning the skins; but if the untanned skins are subjected to the other steps of the treatment filling, su erposing, and washing with benzina pro uct described my invention, and desire to secure by intestinal coating to a filling-bath of yolk of During this dryis obtained having many advantageous characteristics over the untanned skins previously eggs, superposing two or more-pieces thereof 2. A process of making leather, which con sists in subjecting the outer peritoneal intestinal coating to a filling-bath of yolk of eggs and flour, superposing two or more pieces thereof While wet, drying and washing in a fat solvent.
' 3. 'The process of making leather, which consists in tanning the outer peritoneal intestinal coating, subjec'ti to a filling-bath, superposing two or more pieces thereof while wet, and permitting todry in intimate contact.
4. The process of making leather, which' consists in tanning the; outer peritoneal intestinal coating, subjecting to a; filling-bath, super osing two or more pieces thereof While wet, rying and washing in a fat solvent.
7 5. The process of making leather, which 6. As an article of manufacture, a leather I consisting of multiple superposed adherent layers of the tanner outer peritoneal intestinal coating.
7. As an article of manufacture,aleather consisting of multiple adherent d'egreased filled layers of the tanned outer peritoneal intestinal coating.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
