SPECIFICATION forming part of Letters Patent No. fl80,719, dated August 20, 1901.
Application filed October 13, 1900.- Serial No. 52.945. (N0 specimens.)
To all whom it may concern:
Beit known that I, FRIEDRICH LEHNER, a citizen of Germany, residing at Zurich, Switzerland, have invented certain new and useful Improvements in Processcs ol? Manufacturing Artificial llorsehair; and I do hereby lulose, nitrocellulose, pyroxylin, alone or mixed. and in general with solutions or baths of cellulose derivatives, which, as is well kno u, are adapted to be spun or drawn out int a continuous thread in a precipitating be, h or liquid or in the air. Such solutions of c llulose derivatives, pure or mixed, have been escribed, for example, in United States Patents No. 304,559, of December 18, 1888, and No. 531,158, of December 1 8, 1894:, to De Ghardonnet; No. 571,530, of November 17, 18.96 to Langans; No. 550,392, of May ,5, 1896", e be. 562,626, of June 23, 1896,10 myself, and other patents and publications.
As is known, natural horsehair consi of a rather thick untwisted and solid thread. It now it is attempted to make a fictitious horsehair thread from the above materials by causing nitrocellulose or other soluti n to be drawn through an orifice corresponding to the thickness of natural horsehair, an allow ance being made for the shrinkage of the thread 01.1 solidifying, it will be found that such thread will be very brittle and will possess little tensile strength. It will be im possible to tie such a thread or to join annulber ct; such threads, since they will tear or rupture at the points of connection with extreme facility. It is the object of my inventionto overcome this great defect, and for this purpose lllY'illVGllhlOil consists in concurrcntl y drawing out a plurality of threads from the solution and then uniting the threads while they still are capable of running together and merging into each other.
I will now describe in detail what I consider the preferred method-of carrying .my invention into eiiect.
I take any well-known nitrocellulose, pyroxylin, or other solution of a cellulose dcrivative-such as set forth, for example, in the patents abovcn1cntionednud I draw a number (two or more) of thin threads from such solutions through suitable orifices or otherwise through a congealing or precipitatin g bath or into the air, the aggregate thick ness of such thin threads being such as to form together a thread of the thickness of horsehair. The component threads are then allowed to run together and merge into a. single thread, while they have still suiiicient fluidity to so combine. This combination of the threads I have found must take place very shortly after they have left the solution or spinning orifice, as otherwise they wouldnot completely merge into each other to form an integral single thread. The. artificial horse hair thread so obtained may then be treated in the manner well known for such fibers, and accordingto the starting material employed is subsequently denitratcd, dyed, doc. and will then serve as a perfect substitute for natural horsehair.
What I claim ,and desire to secure by Letters Patent of the United States, is-
The process of preparing artificial horsehair which consists in drawing a plurality of threads from a bath of cellulose or cellulose derivative and Biting such threads while they are yet capable of merging into a single thread. I
In testimony whereof I affix my signature in presence of two witnesses.
