Patented July 19, 1938 UNETED STAT-ES PATENT OFFICE .2,124,123 GOLF PRACTICE MAT 0R THE LIKE Mitchell G. Rosengarten, Philadelphia, Pa. Application April122, 1937, Serial No. 138,284 5 Claims. (Cl. 273-33) My invention relates to golf-practice apparatus cardboard disc, the bristle wires >serve to keep it and the like, and especially to a mat from which golf-missiles can be played or driven. The invention also involves a novel combination of a mat 5 and a coacting missile-disc. For convenience, I use the word “driving” in a broadway to express the playing of a golf missile with any golfclub or the like, without regard to the strict technicalities of golf parlance as to the particular club or im10 plement used, or the `force of therstroke: -e. g., as including equally the very `strongest strokes with a driver and the very‘lightest shot. I aim to provide a mat that will simulatefas‘closely as possible the conditions of ordinary-outdoor golf 15 on a regular golf course. In ordinary golf, some kstrokesfare made from a “tee” resting on bare ground; but more are made without any tee, from the greensward‘or fairway: i. e., with the ball lying in grassor on earthithat 2c is rather yielding if touched or struck bythe club. In some places where golf shots are practiced, ordinary cocoa mats (like doormats) are used `to simulate grass; 'but such mats do not last-well under the severe punishment of continual use; if.; do not really approach actual'playingconditions very closely; and offer some danger of catching the club on a hard downward stroke andv snapping it off, or injuring the wrist of the player. iFor practice with light cardboard missile-discs, mats 30 and tee supports are disclosed in my .Patent No. upright without the use of a tee device or other holding means, and release it easily and natu rally When it is struck. Various other features and advantages of my f5 invention will appear from the following descrip tion of a species or form of embodiment, and from my drawing. All features shown or de scribed are, indeed, of my invention, so far as novel over the prior art. 1-0 In‘the drawing, Fig. I is a tilted or perspective vview of one form of mat constructed in accord ance with my invention, with a missile disc there on ready for driving. `FigsII and IIIare fragmentary sectional views, 15 taken as indicated by the lines and arrows II--II and III-III in Fig. I. yFigs.

The underside ofthe backplate -I l .may;have„a sheet or pad of 55 2 2,124,123 felt Il cemented to it, to prevent the mat from slipping on the floor or scratching it. Fig. I shows a cardboard missile-disc 20 (such ends of the wires in Figs. II and III, though a trifle lower. As already stated, the construction of ordinary as mentioned above) stuck in the mat in con venient position for driving; and in Figs. II and III, the outlines of such a missile-disc are indi card-clothing answers very well for the facing 5. Such card-clothing commonly comprises a stout, flexible base 'l with fairly short bristle wires 6 cated in dot and dash lines. The upstanding bristle wires 6 hold the disc 20 securely, by en gagement of the disc margin amongst them, or by impalement of the margin on some of the fixed therein and projecting a certain uniform distance therefrom, parallel with one another. wires, or in both these ways. The proper en gagement of the cardboard disc 2U with the bristle wires 6 occurs automatically: all the play er has to do is to press the disc edge firmly 15 against the bristle surface of the mat, and then release the disc when he feels that he has forced it into the mat somewhat. The disc edge impales itself firmly on such wires 6 as it encounters end on, and elastically deflects other wires 6 slightly, 20 the wires 6 being resiliently flexible relative to the general plane of the mat. The player then plays or drives the disc 20 just as if it were a golf-ball lying on the fairway, or on a tee. The disc 20 releases itself easily from the ends of the 25 bristles 6, which slope diagonally upward in the direction of the disc flight, as shown in Fig. II the release of the missile disc 28 is facilitated by the downward displacement of the facing 5 by the club and the lateral ñ‘exure of the bristles 6, 30 both of which also avoid injury of facing and bristles by the club. If desired, of course, a tee clip such as shown in my Patent No. 2,011,014, granted August 13, 1935, or in my application Serial Number 15,550, filed April 10, 1935, could 35 be used in the mat with a missile disc 20; but in general it is unnecessary. ' When a golf ball or any ordinary form of golf practice missile is used, it is merely laid or thrown on the surface of the mat, as on a fair way, Without any attempt to press or force it down on the bristles 6, as described above in the case of the cardboard disc 20. For any type of missile that might be used on it, from an ordinary golf ball to a cardboard 45 disc, my mat affords conditions closely approxi mating those on the ordinary fairway: i. e., when a club strikes or scrapes over the mat, the bristles 6 bend down before it with a yielding cushion ef fect, like the turf of a fairway. Like the earth of 50 a fairway, also, the resilient backing 8 under the card cloth or similar facing 5 yields locally to cushion the stroke and let the club pass more easily,-thus minimizing wear on the card cloth. In other words, the facing 5 yields downward un 55 der the pressure of the club, in addition to the lateral yielding or flexure of the wires 6; but the bristles return spontaneously to erect, even-sur faced condition. Provided the stroke is made with the bristles 6 as shown in Fig. II (and not 60 against them or cross-wise), it has been found The base 'l may be of rubber, leather, or stout textile fabric: I prefer textile fabric, which may 10 advantageously be saturated with rubber, which is afterward vulcanized to leave the rubber elastic but ñrm. The wires 6 are preferably fairly stiff, resiliently flexible, fine steel wires such as gen erally used in card cloth, and set rather close to 15 gether. Fine wires 6 projecting about a quarter of an inch from the base and set about thirty three thousandths to one twentieth of an inch apart answer very well, particularly with a card board disc 20 about thirty-nine thousandths of 20 an inch thick.. In the drawing, the size and spacing of the wires 6 is of course exaggerated for the sake of clearness of illustration. Commonly, pairs of adjacent wires 6 of card cloth are united behind the base l, so that they are in effect like 25 staples driven through the base from behind. In card cloth, the wires 6 are customarily bent slightly all in one direction, as shown in Fig. II, which is advantageous for my purpose. The lat» eral flexure of the wires 6 seems to be partly due 30 to their own resiliency, and partly yielding in the mat. The rubber saturation of the mat min imizes internal Wear amongst its threads due to this. One commercial grade of card clothing which I have used with good results is #28 CWC 35 of American Card Clothing Co. For the elastic backing 8, I may use sheet sponge rubber about a half inch thick, preferably fairly stiff and resilient rather than very soft. A commercial grade which has given good results is 40 4075 black sponge rubber of Lee Tire and Rubber Co. Having thus described my invention, I claim: l. Game apparatus comprising in combination a plain cardboard missile-disc, adapted to be propelled by a stroke of a_ golf club against its edge, and a driving mat comprising a facing mounted to yield resiliently downward under a stroke of a club and surfaced with upstanding bristle Wires resiliently flexible relative to the 50 facing and of such length and stiffness and so spaced as to impale and receive amongst them the margin of the plain cardboard missile disc, when it is pushed edgewise against the facing, so that the facing and its bristles hold the disc up 55 right to receive the stroke of the club, yet tem porarily yield downward and laterally under such stroke, thereby avoiding injury of the facing and even with a stroke that has a somewhat exagger releasing the disc more easily. 2. A golfer’s driving mat comprising a facing 60 composed of a flexible base surfaced with bristle wires upstanding free of lateral support above ated downward component. said base, and resiliently flexible relative thereto, impossible to “catch” the club in the bristles 6, With a cocoa mat, such catching of the club sometimes happens, 65 resulting in a broken stick, or an injured wrist for the player. With an outward-bevelled metal surfaced frame I0, it is also practically impos sible to catch and break the club against the frame by an ill-aimed stroke,-unless, perhaps, the lower edge of the club-head should hit squarely against the angle-bend between the -top surface of the frame and the bottom plate l I, which is very unlikely. The edges of the facing 5 and backing 8 are effectively protected by the 75 frame I0, whose top edge is almost even with the so that they yield laterally under a golf club stroke at a missile on the mat, and means for 65 mounting said facing to yield resiliently down Ward under such a golf club stroke, all so that the bristle wires and facing spontaneously re turn to erect, even-surfaced condition after the stroke. 70 3. A golfer’s driving mat comprising a facing composed of a flexible base surfaced with bristle Wires upstanding free of lateral support above said base, and resiliently flexible relative thereto, so that they yield laterally under a golf club 75 2,124,123 stroke at a missile on the mat, and a resiliently yielding layer or pad of elastic sponge rubber under said base backing said» facing, all so that while said facing yields resiliently downward under a golf club stroke at a missile on the mat, the bristle wires and facing spontaneously re turn to erect, even-surfaced condition after the stroke. 4. A golfer’s driving mat comprising a struc 10 tural back, a resiliently yielding elastic pad on said back secured to its surface, and a facing on said pad comprising a ñexible base secured to 3 the surface of the pad and itself surfaced with upstanding bristle wires resiliently flexible rela tive to said base. 5. A golfer’s driving mat comprising a facing composed of a flexible base surfaced with up standing bristle Wires resiliently flexible relative to said base, a resiliently yielding elastic pad under said base, and a frame enclosing the edges of said facing and pad, and at one side over hanging the facing bristles and beveled outward 10 and downward.
