To all whom, t may concern.-

Beit known that I, JOHANN SCHMITT, asubject of the King of Prussia, German Emperor, and a resident of Cologne, in the Province of the Rhine, Kingdom of Prussia, German Enipire, have invented an Improved Knitting- Machine for the Production of Meshes with Crossed Threads, (for which patents have been obtained in Germany, No. 79,262, dated May 1o 21, 1894; in Sweden, No. 6,612, dated June 7, 1894; in France, No. 239,111, dated June 7, 1894; in Belgium, No. 110,323, dated June 7, 1894; in Switzerland, No. 8,865, dated Julie 27, 1894; in Italy, No. 36,671, dated June 27,

i i5 1894; in Great Britain, No. 12,424, dated June 27, 1894; in Hungary, No. 1,091, dated September 11, 1894; in Austria, No. 44,/5,607,

dated October 24, 1894, and in Denmark, No.

479, dated March 26, 1896,) of which the folzo lowing is an exact specification.

This invention refers to knitting-machines in which the meshes are formed on and held by a rotating spiral of horseshoe-like configuration, the two parallel ends or end windings of which rotate in opposite directions, so that the meshes are taken up by one end of the spiral and dropped by the other. A knitting-machine of such akind is shown, for instance,in my United States Patent No.421,526,

3o dated February 18, 1890, and there is also shown a needle, or, more precisely, a threadguide, which catches up the meshes falling off the one end of the spiral and which hangs new meshes onto the other end of the spiral.

I therefore do not lay any claim upon said known parts; but what I claim and what my improvements in knitting-machines of the said kind consists in is, iirst, a special coniiguration of the first winding of the spiral,

4o or of that end of the latter which catches the meshes up, respectively, and, second, a spiral configuration of the head of the thread-guide. The object of my invention is to produce on a knitting-machine of the kind in question meshes with crossed threads, or a knitted fabric consisting of such meshes, respectively.

In order to make my invention more clear, I refer to the accompanying drawings, in

which similar letters denote similar parts throughout the different vie ws,and in which- 5 o Figure 1 is a plan view of the two ends of the spiral of the knitting-machine aforementioned together with the main portion of the thread-guide. Fig. 2 is a front view of the parts shown in Fig. 1, and Fig. 3 represents 55 a portion of the spiral together with some single meshes and some interlocked ones.

To produce meshes of the kind in question,

I cause the thread to pass through the ear of the thread-guide not from the rear side of 6o the latter, as hitherto done, but from the front side thereof, and also the meshes are consequently taken up not from the rear side of the thread-guides, but from the front side of the saine. In order to enable the first winding of the spiral to catch the meshes up in said way, I have shaped the end portion or point of said winding, as well as the point or head of the thread-guide, in a manner as follows: 7o

First. The head a/ of the thread-guide d is provided with a projection a2, situated upon the front side of the guide a. Said projection contains the eye a3.

Second. The end portion c of the iirst winding c of the spiral is situated in avertie-al plane standing in front of the plane of the front surface of the projection a2, aforementioned, and the point proper, c2, of said end portion is directed rearward or bent in a direction to the 8o front surface of the guide a, respectively. 1f, therefore, the thread e' passes through the eye d3 from the rear side of the thread-guide a and if the thread is carried by said guide through the mesh i2 next to be dropped by the last 85 winding of the spiral, there results from the presence of the projection d2 of the guide a a space between the thread portion e" and the respective opposite portion of the guide a. Said space is necessary for allowing the first 9o winding of the spiral to catch the thread up, but for that purpose the end portion c' of said winding must have its point proper, c2, bent so as to enable this latter to take behind the thread or into the said space, respectively.

Having thus fully described the nature of this invention, what I desire to secure by Letters Patent of the United States is 1. In a knittingmachine having a rotating spiral for holding and transporting the meshes, and a reciprocating thread-guide for catching up the meshes dropped by the one end of said spiral, and hanging new meshes upon the other end of the Same, the combination with the said spiral, and With said 1hreadguide, of a projection a2 arranged at the head and upon the front surface of the same, and containing the eye for the thread; and of a rearwardly-bcnt-oif portion c2 forming the point proper of the irst Winding of the spiral, and being situated in front of the said thread-guide, and adapted to take around the projection a2 of the same, substantially and for the purpose as described.

2. In a knitting-machine having a rotating spiral for holding and transporting the meshes, and a reciprocating thread-guide for catching up the meshes dropped by the one end of said spiral, and hanging new meshes upon the other end of the same, the combination with the said spiral, and With said thread-guide, of a projection a2 arranged at the head and upon the front surface of the same, and containing the eye for the thread; and of a rearWardly-bent-oi point c2 forming the end proper of the first Winding of the spiral, and being adapted to take around said projection; an end portion c forming the connection between said point c2 and thc other portion of said first Winding, and being situated in a Vertical plane standing in front of the front surface of the said threadguide, substantially and for the purpose as described.

In testimony whereof I have signed this speciication in the presence of two subscrib- 4o ing Witnesses.
