THREADMADE FROM HORSEHAIR AND PROCESS OF FORMTNG THE THREAD.

Specification of Letters Patent.

Patented Apr. 1, 1913.

Application filed October 30, 1912. Serial No. 728,564.

To all whom it may concern:

-Be. itknown that I, REINHOLD GRABEIN,'21

. subject of the King of Prussia, residing at Richtstrasse 9, Forst, Lusatia, Germany, have invented new and useful Improvements in Thread Made from Horsehair and Processes of Forming the Thread, of which the following is a specification.

This invention relates to thread made from horsehair and to the process of forming the thread.

One of the objects of the invention is to provide a thread of this character in which the horse hairs of which the thread is composed cannot be withdrawn and in which the ends of the hairs will not project through the covering of the thread.

Another object is to provide a simple method by which such a thread may be made.

Other objects will in part be obvious and in part be pointed out hereinafter.

Referring to the accompanying drawings, Figure 1 represents a machine by means of which the process may be carriedout. Fig. 2 shows on a greatly enlarged scale, the form which the hair acquires after being curled or corrugated. Fig. 3 is a sectional view of a thread drawn to a greatly enlarged scale. Fig. 4 is a view similar to Fig. 3.showing a slightly modified form of thread.

According to the usual practice, when horse hair is formed into a thread, it will, if the thread is bent, Work loose, as a result of which the ends of the hairs will project from the thread or from the cloth fabric made from the thread. This feature is a very disagreeable one, especially where the fabric formed of horsehair thread is used for the lining or stiffening of clothes, as the projecting ends of the hair are apt to stick into the body of the person wearing the clothes. Furthermore, the hairs can be easily drawn out of the fabric, thus destroying the stiffening quality of the same. These disadvantages increase as the length of the hairs which are used decreases. 'In other words, the shorter the hairs which form the thread, the more pronounced will be the.

working out of the hairs.

The principal feature of this invention is to provide a thread, and a process of forming the same which will avoid the above mentioned disadvantages of the ordinary horse hair thread and the fabric c011- structed therefrom.

By way of example, in order simply to illustrate the process, there is shown a hair feeding apparatus such as 'is described and claimed in applicants co-pending application, Serial #602,617, filed January 14th, 1911, to which application reference is made for a detailed description of the apparatus. It will, of course, be understood that the process or the article is not limited in any way to this particular form of apparatus, as, of course, other apparatus might be used without in any .way departing from the spirit of the invention.

Referring to Fig. 1 of the drawing, 1 represents a trough in which the horse hairs are placed and which is provided with a longitudinal slot formed in its bottom, through which slot the ends of the pincers 2, mounted upon a rotatable disk 3 may pass, as described in the above referred to application. These pincers open as they enter theslot in the trough, then close so as to grip one or more of the hairs in the trough to feecl'the same forward, and then again open in order to release the hair or hairs, as the ends thereof engage between the roughening or corrugating-rollers 1. The hairs may be fed to the'rollerssingly, or if desired, two or more hairs may be fed at one time and the hairs are so fed that they will overlap the preceding hairs. As the hairs pass through these rollers, they will, of course, be curled or corrugated, as clearly shown in Fig. 2 and the overlapping portion of the hairs will, to a certain extent, interlock with one another as illustrated in Fig. 3. If a plurality of hairs are fed to the corrugating rollersat each rotation of the pincers, the hairs of each set will, of course, be similarly waved or corrugated "and will interlock with one another and the overlapping ends of the sets of hairs will -5 are led through a funnel 6, from which they pass through a hollow spindle 7 of any approved construction. Before passing through the hollow spindle, the hairs are wound about with binding threadB in the well known manner. This binding thread will, of course, lie in the corrugations formed in the hairs, as-shown in Figs. 3

therefrom will be impossible.

and 4:, and-will serve to hold the individual hairs firmly in position, from which it will be understood that not only are the free ends of the hairs held against projecting out of the finished thread which emerges-from the lower end of the hollow spindle, but the hairs will be so firmly held in position in the finished thread that their withdrawal Even if the thread should be cut at a point intermediate the ends ofone of the hairs, the'cut ends cannot project from the thread, as they will be held in position by reason of the corrugations with which the binding thread engages.

Having described the invention to the details of which disclosure, it is not, of course, to be limited, What is claimed as new and What is desired to be secured by Letters Patent, as set forth in the appended claims 1. A thread comprising corrugated horse hairs in overlapping relation to one another and a binding thread wound around said hairs. v

2. A thread comprising corrugated horse hairs in overlapping relation to one another, the corrugations of the overlapping portions of the thread interlocking with one another, and a binding thread wound around said hairs.

3. The herein described method of forming a thread from horse hairs which consists in feeding the hairs in overlapping relation to one another, corrugating the hairs and winding a binding thread about the corrugated hairs.

In testimony whereof I have signed my name to this specification in the presence of two subscriblng witnesses.

REINHOLD GRABEIN.
