CHARLES HENDRICKSON, OF NEW BRIGHTON, NEWV YORK.

T E N N l S N ET SPECIFICATION forming part of Letters Patent No. 497,662, dated May 16, 1893.

Applicationfiled November 25, 1892. Serial No. 453,077- (No model.)

To all whom it may concern:

Be it known that I, CHARLES HENDRICKSON, a citizen of the United States, residing at New Brighton, in the county of Richmond and State of New York, have invented new and useful Improvements in Tennis-Nets, of which the following is a specification.

This invention relates to tennis nets and consists in certain novel features as described and shown in the following specification, refence being had to the accompanying drawings in which- Figure 1, represents the center piece of a tennis net composed of double thread loops, the said loops alternating with open spaces at the ends of the center piece. Fig. 2, represents the netin course of completion. Fig. 3, represents a tennis net made according to the old style.

In Letters Patent No. 394,138, granted to George F. Shepard, December 4,1888, a tennis net is described, the end portions of which are composed of single cords interlocked to form meshes, each bounded by a single cord, while the middle portion of said net is composed of cords'interlocked to form meshes, each bounded on all sides by two cords, forming an outer mesh and a smaller mesh just within and in the plane of the first or in other words, said tennis net is composed of end portions having single cord meshes and of a middle portion having double cord meshes. Tennis nets of this kind have been manufactured and sold in the United States at least for ten years last past and in order to explain the advantage of my invention I have represented in Fig. 3 atennis net of the kind described in said Patent No. 394,138. In this figure the letter A designates the middle portion composed of double cord meshes and B B are the end portions composed of single cord meshes. In the process of knittinga net of this kind a device is used which is technically called a needle but which resembles the shuttle of a loom and which contains two cords. The operative first forms the mesh 1) (Fig.3), then the meshes 19 b then the meshes b to 19 then the meshes b to b and so on and until the line of meshes b b is reached. The operative uses only one of the cords in his needle but when he reaches the mesh 12", the second cord of the needle is introduced and this second cord is continued in forming the first two double cord meshes .in'the line b b butif the third mesh in this line is reached, which is a singlecord mesh, one-of the cords in the needle has to be cut and its end tied by a knot to one of the meshes already formed and then the remaim it to one of the meshes already formed requires much time and the knots which appear on the net impart to the same an unsight-1y appearance. In order to overcome these disadvantages I first complete the mid-. dle portion A of my net with the double cord needle and as shownin Fig. lot the drawings this middle portion is provided at its ends with double cord meshes a a a &c., with intervening open spacess s, &c., and when the middle portion A has been finished with a double cord needle, I take a single cord needle for the purpose of finishing thesingle cord end -portions B a portion of one of which is shown in Fig. 2. In order to effect this purpose I draw the end 0 of the cord out 1 of the needle and tie the same to the middle portion A at 0*. Then I finish the single cord mesh (Z and at the same time I form a depending loop (1* (technically called a jocker) which is afterward used in closing the open space 8.

By referring to Fig. 2 it will be seen that when the net is completed, the double cord meshes a a, &c.,of the middle portion A are bounded at their junction with the single cord portion B by three cords while the mesh es s s, &c., are bounded at their junction with the single cord portion B only by two cords so that when my net is completed, it can be readily distinguished from the tennis nets heretofore known. It will also be seen from this explanation, that I am' enabled to knit the middle portions A composed of double cord meshes by themselves, so that one man can devote his whole time to knitting these middle portions while other men are engaged in joining to said middle portions the end e V n r 497,662
