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

Fig. I shows a cardboard missile-disc 20 (such

As already stated, the construction of ordinary

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
Having thus described my invention, I claim:

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

With a cocoa mat,
such catching of the club sometimes happens,

the player.
With an outward-bevelled metal

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
