INVENTOR ATT( )RNEY The invention relates to a protective device or fence particularly designed for use in connection with playing fields such as a baseball diamond or the like which is surrounded by a rigid wall, the protective device being designed to prevent players from crashing into the wall in the course of the game and thereby sustaining injury.

The present application is a continuation-in-part of my application Serial No. 241,118, filed August 9, 1951, now abandoned.

The primary object of the invention is to provide a protecting device in the form of a fence including a flexible screen portion tightly but yieldingly supported from above and at its ends and serving as a buffer to protect a player from coming in contact therewith from injury as a result of such impact.

A further object of the invention is to provide improved supporting means for the protective screen adjacent the corners of the wall.

Another object is to provide means for returning to the playing field any balls which may have passed under and beyond the protective screen.

Other objects will be apparent from a consideration of the accompanying drawings and the following detailed description:

Referring to the drawings, reference numeral 10 denotes generally a baseball playing field which may include a diamond proper designated by the numeral 11 and including home plate 12, first base 13, second base 14 and States Patent 0 ICC third base 15. The field is normally separated from the spectators by means of a low, rigid wall extending around the field, this wall being designated by the numeral 16. During the course of the game players in the outfield frequently have to run for a ball and may sustain injury by crashing against the wall, particularly the portion of the wall surrounding first, second and third bases. There is little or no danger of damage from the wall surrounding the remainder of the field.

In accordance with my invention a suitable anti'crash fence 17 is provided extending around the inside of the wall from a position adjacent first base and extending to a position beyond third base. The fence 17 is flexibly but securely anchored adjacent its ends 18, 18 and three corners 19, 1'9, 19.

Preferably the fence comprises two flexible screen portions 20 and 21 suitably supported from above at dilferent levels and at different distances from the outer wall, the upper and inner screen 20 being adapted to protect a player running after a high ball, and the lower and outer screen 21 being adapted to protect a player in stoopedover position attempting to catch a low hit or grounded baseball. The screens 20 and 21 are preferably formed of relatively strong wire of reasonably fine mesh and may be suitably padded if desired. In accordance with my invention each screen may be continuous and is resiliently but firmly supported both at the two ends 18, 18 and at the three intermediate corners 19, 1'9, 19 of the fence by means of a series of cables secured thereto, which cables are connected to suitable springs anchored to upright posts located at the two ends and three corners of the fence. Sagging of the screens is prevented by resilient means engaging the top cable of each screen at suitable intervals and supported by curved overhanging arms attached to suitable upright posts.

As shown, the horizontal cables carrying upper screen 20 are designated by the reference numeral 22, and those supporting the lower screen are designated 23, and all may be of the same general construction. These horizontal supporting cables are preferably arranged in groups, one group extending from one end 18 of the fence to the adjacent corner 19, the next group extending from the first corner to the second, and the next group extending from the second corner to the third, and the last group extending from the third corner to the remote end 18 of the fence. Each group of cables passes over pulleys carried by upright posts located near the ends of the cables and the end portions of each cable are secured to coil springs anchored to an upright metal post located either at one of the ends or at one of the corners of the fence. Thus, the end portions of the first group of cables 22 pass about pulleys 24 carried by an upright metal post 200 and are preferably embedded in slots in an upright concrete post 25 adjacent post 200 and spaced outwardly a suitable distance from the wall 16, and are connected to end springs 26 which are carried by an upright metal post 27 embedded in the ground and preferably secured at its upper end to the wall 16. Similarly, the ends of the first group of cables 23 supporting the lower screen 21 pass around pulleys 29 carried 'by metal post 202 adjacent concrete post 30 and are connected to end springs 31 also carried by the post 27. Supporting collars 201 shown in detail in Fig. 11 may be mounted on post 27 to suitably space the end springs 26 and the end springs 31.

At each of the corners 19 the individual cables of each group of cables 22 supporting the upper screen 20 pass around pulleys 35 carried by an upright metal post 36. Similarly, the individual cables of each group of cables 23 supporting the lower screen 21 pass about pulleys 37 carried by post 38. At these corners 19 the end port-ions 40 of each of the cables 22 supporting the upper screen Patented Mar. 19, 1957 are connected to coil springs 41, whichin turn are secured to upright end posts 42, which posts are embedded in the ground and at their upper ends are secured to the wall 16. Similarly, the end portions '43 of ca'blesr23 supporting the lower screen 21 are secured to coil springs 44 which are also carried by the posts 42. Supporting collars 2&3 similar to the collars 201 on. post 27 may be employed on rods 42 to space springs 41 and 42, and like collars 204 and 205 may be employed on posts or rods 36 and 38 to space pulleys and 37 respectively.

In addition to the resilient end and corner supports the screens 29 and 21 are provided at spaced intervals with resilient upper supports which serve to prevent sagging. As shown, upright metal posts are provided at suitable intervals along the inside of the outer wall and located slightly away from such wall. Each upright post 50, is provided with a horizontally extending curved or arched arm or goose-neck 51, these arms serving to support the screen 20 from above and prevent the same from sagging. Similarly, shorter arched arms 52 are carried at spaced intervals by the uprights 50 and serve to support the lower fence or screen 21. As shown, connecting means are provided between the arm 51 and the screen or fence comprising an enclosed spring unit or member 69 having an eye connection 62 with the curved arm 51, and a lower eye connection 63 with the upper cable 22 which supports the upper screen 20. Similarly, an enclosed spring member 64 similar to the spring member is provided with an upper eye connection 65 secured to the curved arm $2 and is provided with a lower eye connection 66 connected with the upper cable 23 ofthe lower screen member 21.

I As shown, the lower screen 21 terminates a few inches from the surface of the ground, which is suflicient to allow a ball to pass thereunder. 21 and the outer Wall 16 an inclined ball-return member 70 is provided which causes any balls passing beyond. both screens to roll back onto the playing field.

Additional supporting cables 81 and 82 are provided which are adapted to pass through the eye connections 62 and 65 carried by the spring members 60 and 64', respectively, these cables being anchored at their ends to securing members 83 carried by the outer wall. These additional cables are anchored at the corners 19 to up right posts having upper and lower tie rods 91 and 92 connected with the cables 81 and 82, respectively.

Fig. 8 illustrates a modified form of playing field designated 10' herein shown as of generally rectangular shape similar to the playing field 10 shown in Fig. 1, except that it includes an inset or inwardly directed sharp corner portion 10f requiring additional protection. The field 10' is equipped with a protecting fence similar to that shown in Fig. 1 except for the inwardly directed portions designed to protect the sharp corner 100, and except for these inwardly directed portions the parts of the fence and the'supporting elements therefor may be designated by the same reference numerals designating corresponding parts in Figs. 1 to 7.

As. shown, the upper screen portion 20 of the fence and the cables 22 supporting the same extend inwardly at 20 and 22 and then pass in front of a yieldingly supported flat plate 161 equipped with a plurality of rows of cable holding means 102 detachably secured to the plate by means of nuts 103 or the like at the rear of. the plate. The plate 101 may be of any suitable size and material. A plate 24 wide and 36" long has been found satisfactory. The plate is yieldingly supported in spaced relation to the corner by means of a series of enclosed compression spring members 164 secured, to the center of the plate by a series of fastening'devices 105 in vertical-alignment, and secured at their opposite ends toan upright post 106, T-shape in cross section and embedded. in concrete, the post being erected adjacent, the

corner 100.

Similarly, the lower screen. portion 21 of thefence Between the screen.

and. the supporting cables 23. therefor are inset at the corner, as indicated at 21' and 23' and are then passed over and secured to a plate similar to the plate 101, which plate 110 is yieldingly supported in a manner similar to the plate 101.

The invention has been described in detail for the purpose of illustration, but it will be obvious that numerous modifications and variations may be resorted to with- 3 out departing from the spirit of the invention.
