When the net has been fitted and rod engaged thereby; Fig. 5 is a side elevation at each of its ends with one of the rods l2, and of a modified structure, and Fig. 6 shows another the rods placed in position between the ends of modification. the spring arms, the tendency of the spring arms With reference to the embodiment of the into exert a pull toward the spring post to which vention shown in Fig. 1, the supporting bracket they are secured, will draw the net longitudinally is generally indicated at I. This bracket is preiand thus hold it taut across the table. Since the erably, but not necessarily, constructed of flat 5 springs can be flexed to a considerable extent, it

will be obvious that variations in the lengths of the nets provided can be compensated for and the nets used will always be held taut. When it is desired to remove a net, the rods l2 at the opposite ends of the net are simply removed from the springs, and a replacement of the net means merely slipping the rods back into place, the springs acting at once to take up the slack in the net without requirin any manual adjustments.

It is to be noted that the springs and the rods supported thereby are attached to the inside faces of the upright posts 3 so that the outer face of the post is smooth and clear of projections. Thus, the likelihood of a player injuring himself on protruding parts is completely obviated.

In the embodiment of the invention shown in Fig. 5, the rod I2 is held between the laterallybent ends 2| of a bracket 20, which might be of springy r resilient material, and extending from the bracket is one or more, and in the embodiment shown, two pins or studs .22 which slide through apertures provided in the upright post 3 of the supporting bracket. On the end of each of the pins or studs 22 is a head or nut 24, and confined between the head or nut 24 and the outer face of the upright post 3 is a coil spring 23 extending around the pin 22. Through this arrangement, a resilient pull is imposed on the rod 12 and the end of the net through which the rod is fitted. While the structure shown in this embodiment of the invention causes projecting elements to become disposed on the outside of the post 3, the shape and disposition of such elements is such that the same can be readily protected by suitable rubber shields or sleeves, not herein shown, in order to more clearly disclose the construction.

In the embodiment of the invention shown in Fig. 6, a rod 25 is shown as extending through the hem II of the net, said rod being provided at its opposite ends with an eyelet 26. A spring 2'! has one end attached to the eyelet and its other end secured to the post 3, the springs tending to pull the end of the net toward the post. While two springs 2'! are shown, this number may be increased if desired.

While I have shown several embodiments of th invention, other embodiments and changes in the disclosed structures will be readily apparent to those skilled in this art. In the disclosed structures, the net is drawn taut with the imposition of a resilient pull on its opposite ends. The result is that all slackness in the net is taken up, differences in net-lengths is compensated for, manual adjustments are rendered unnecessary and setting up and taking down of the net is greatly simplified.

I have herein suggested that the net employed might be provided at its ends with a hem to form an elongated pocket to fit the rod 12, but it will be understood that strings of the character used on some types of nets can be used to attach the nets to the rods or possibly directly to the spring arms l5. It is also possible to facilitate the placement of the stub-ends of the rods into the apertures l8 by the provision of grooves in the ends of the spring arms adjacent to the apertures and whereby the ends of the rod may be easily snapped into the apertures and readily manually removed from engagement therewith.

These and other modifications are comprehended as being within the scope of the invention and the claims appended hereto.

What I claim is:

1. A net holder comprising, a bracket having an upright post, a leaf spring secured to the inner face of the post, said spring having a pair of resilient arm portions bowed or shaped to cause the same to extend toward the inner face of the post, lateral ends on said arm portions extending in a direction away from the post, a rod holding one end of a net, said rod being resiliently clamped between the lateral ends of the spring arms, said ends being apertured to receive the ends of the rod.

2. A net holder comprising, a bracket having a rigid upright post, a. flat leaf spring located on the inner face of the post, said spring being rigidly and non-pivotally attached at a substantially central point to the inner face of the post, said spring having a pair of resilient arm portions bowed or shaped to cause the same to extend toward the inner face of the post, lateral ends on said arm portions extending in a direction away from the post, a rod holding one end of a net, said rod being resiliently clamped between the SAMUEL NADELSON.
