s claims. 1

.-Theprincipal objects of this invention are to provide a golf practice device on which an individual may practice the striking of a golf ball. with perfection of movement within extremely small space limitations and to indicate to the player with reasonable accuracy the distance and direction of the shot The principal features of the invention consist in the novel construction of a device whereby a means forv projecting a ball over a miniature coursezis operatively connected through a gear train with .a rotatable member adapted to be struck. with .a golf club, such mechanism being pivotally mounted so .as to swing in response to the direction of the stroke of the club of the player, thereby effecting the delivery of the ball in a line corresponding with the line of the stroke of deliveryof the player.

In the accompanying drawing: .Figure l is a perspective view of a device to whichmy. improved form of practice apparatus is applied.

Figure 2 is a plan view of the device illustrated in Figure 1 with the platform cover removed.

Figure 3 is a. longitudinal vertical sectional view taken through the linev 3--3 of Figure 2.

Figure 4 is an enlarged perspective detailof the .ball-propelling. mechanism.

. .Figure 5 is an enlarged vertical sectional view vided which will permit such freedom of actionv on the part ofthe player but which will give an accurate indication of the direction and range ofthe stroke without requiring the actual distance so :that the apparatus may be arranged in ag small space, such as within a room, and yet willhave lfull scope in the making of practice shots. f

` The form of thedevice herein shown comprises an"r enclosure I, the side and end walls of which form the boundaries of a, miniature golf course 2 which Vmay be suitably directed to indicate the landscape with a green and fairway with hazards.

At one end of the enclosure is arranged a platform 3 upon which the player stands. In substantially the middle of this platform is arranged an` opening 4 and projecting upwardly from within thev space beneath the platform is an arm 5" tha ball. head 6 of the size and characteristiof agoifgban. A

Arranged within the enclosure beneath the 2 platform 3 and rigidly secured to the bottom of the enclosure, is a vertical standard l, within which is pivotally mounted a bracketmember 8 which is adapted to swing in a horizontal plane.

At one side of this bracket member is arranged an angular-shaped vertical web 9 which supports an arrangement of journal bearings I0, II and I2 which are arranged transverse to the web.

Within the journal I0 is mounted a shaft I3 to which is keyed a spur pinion I4 and also a hollow drum member I5 of a friction clutch device.

A journal I6 mounted on the bracket member 9, in alignment with the journal I0, supports a shaft I'I on one end of which is keyed a clutch member I8 which is provided with suitable clutching means to engage the interior of the drum member I5 mounted on the shaft I3.

The arm 5 carrying the ball 6 is mounted on the clutch member I8 and projects upwardly through the opening 4 in the platform to the height of 'a teed golf ball, so that it rests in the proper position for play, with the player stand ing on the platform at one side of the ball.

Attached to the shaft Il is a counter-balance I9 which-is adapted to return the clutch mem ber I8 and the arm and ball 6 to a normal upright position after it has been struck.

It will be understood that amr suitable form of automatic centrifugal clutch may be used be tween the two aligned shaft members I3 and I7 to transmit the rotative movement imparted to the clutch member I8 `upon thestriking of the ball to the clutch' member I5.

The rotation thus transmitted to the shaft rotates the pinion I4. with a spur-gear 20 mounted on a shaft journalled in the bearing II, which shaft carries a pinion 2|, and the vpinion 2| meshes with a spur gear 22 mounted on a shaft journalled in the bearing I2.

This arrangement of a gear train imparts rotative movement to the gear 22, and the shaft on which it is mounted, on a considerably reduced ratio from the movement imparted to the shaft I3 by the striking of the ball.

A hub member 23V is secured to the shaft on which the gear 22 is mounted and has a radial arm 24 extending vertically upward.

A trough-shaped member 25 is supported by an arm 26 extending upwardlyfrom the pivotal bracket 8. This trough member is formed with a slot 21 in the end adjacent to the arm 24 carff ried'by theses; tram, which enc of the trough The pinion I4 meshesv I and the movement n roll outward over the slightly upwardly inclined surface 28 of the miniature golf course.

This surface may be covered with a suitable surface representing a fairway, and preferably one which will render a slight impedance to the rolling of the ball, and the ball projected from the trough member Will roll in the direction of the.

green 29 arranged at the Y far end of the course.

It will be particularly noted that. the entire ball-projecting device is mounted on a verticalpivot in the standard l, and this pivot isv preferably arranged in alignment with the longitudinal centre of the course. and the balll 6. Consequently if the player swings his club with either a slieing or hooking stroke the stroke will. be. out of line from the longitudinal centre lineandl-the impact ofthe blow againsty the ball tz will be. in anu guiar direction. Such a stroke will cause the en tire bracket member, to swing on its pivot, carrying the ball-projecting device to an angular-.position to either side of the longitudinal centre lili@ of the sol-f course. and the ballliloimtefl in the trough will be delivered in a, line. oliA centre directlv in accordance with the orf centre stroke of the golf club.

The train of gears .set in. motion by the impact of the players stroke. on the ball ti will continue its rotation until the arm 24 comes back to a Vortioal position where it will be; stopped by .tbe member 3.0. which is in the forni of a bell Crank lever nivotally mounted on theunderside of. the platform. 3 and having. the. extension endportion 3l arranged in. a .Convenient position where the player may put his.. foot upon it after striking the ball.. By pressing down on the member 3| the member Sill is tilted on. its .pivot .to brine, tho lower enel inte .the nath of movement the-erm 2G so that the .said ann will be arrested on oomthat the golf ball` which has been pmiected over the fairway will. .roll back. to tbestartinaizoint and will, be .guided inte the holding-trough. 251. by inclined guides 3?..
