8 Claims.

The present invention relates, in general, to machines for picking up objects from the ground and, particularly, to machines for picking up golf balls from golf courses, and the like. Among the objects of this invention is the provision of a simple and sturdy machine adapted to be drawn across a driving range where the driven balls are found, and to pick up the balls and deposit them in a container for that purpose; and the provision of a golf ball retrieving machine which includes a plurality of rubber-tired wheels arranged in such spaced relation that, as the machine passes across the ground on which golf balls are lying, the balls will be picked up by the resilient tire-like peripheries of the wheels and carried by the rotation of the wheels and deposited in a container carried by the machine to receive the balls; while, in its more generic aspects, this machine may be used for picking up crops, such as fruit, nuts, or the like, which are harvested by being picked up from the ground.

This invention further resides in the combination, construction, and arrangement of the parts illustrated in the accompanying drawings and, while I have shown therein what is now regarded as the preferred embodiment of this invention, I desire the same to be understood as illustrative only and not to be interpreted in a limiting sense.

In the drawings annexed hereto and forming a part hereof,

Fig. 1 is a side view of a machine in which the principles of the present invention have been incorporated;

Fig. 2 is a plan view of the machine shown in Fig. 1;

Fig. 3 is a fragmentary sectional view taken substantially along the plane indicated by the line 33, Fig. 2; and

Figs. 4 to 7 are diagrammatic sectional views showing the operation of this machine.

Reference will now be made in greater detail to the annexed drawings for a more complete description of this invention. The frame of this golf ball retriever is indicated in its entirety by the numeral I and includes a pair of

side bars

2 and 3 interconnected by a pair of fore-and-aft spaced crossbars and 6. The front ends of the

side bars

2 and 3 are pivotally connected at 8 to a supporting wheeled front truck In which includes a front yoke H, the rear ends of which are connected by a crossbar l2 secured to the ends of the side bars of the yoke at their upper edges and rearwardly of the pivot points 8, the crossbar i2 overlying the front portions of the

side bars

2 and 3. The forward portions of the truck frame converge and carry suitable bearing means in which the upper end of the spindle section Id of a wheel fork I5 is rotatably positioned. The lower portion of the wheel fork receives a front supporting wheel IS. A stub tongue I8 is fixed to the upper portion of the wheel fork l5 and pivotally receives the rear end of an associated draft member l9 by which the machine is drawn.

The rear ends of the

side bars

2 and 3 are formed to extend downwardly and rearwardly, as indicated at 22 and 23, and these frame portions are apertured to receive a transverse axle 24 on which a plurality of wheels 25 are mounted. The wheels may be journaled on the axle, or they may be fixed thereto and the axle journaled in the

frame portions

22 and 23, as desired. Each wheel 25 includes a pair of dished or convex web members 26 which are apertured to receive the axle 24, and each wheel is provided with a rubber or rubber-like tire 21 which is substantially round in cross-section. The wheels are separated by spacing drums 28 and the drums and wheels are held in proper interconnected relation by four bolts 29, extending therethrough. The wheels are so spaced that, when they roll over a golf ball lying on the ground, the ball is held between the tire-like peripheries or tread portions of the adjacent wheels and are retained frictionally therebetween. Fig. 4 shows the machine approaching a golf ball on the ground and Fig. 5 shows how the weight of the machine will force the ball into engagement with the tires of two adjacent wheels, which roll together by virtue of the spacing drums 28 and the bolts 29.

A curved upper shield or guard 30 is carried by the frame I above the wheels 25. The front edge of the shield 3!) is connected in any suitable way to the rearward crossbar t, as by lugs 34, as shown in Fig. 3. The shield 30is curved concentrically with the wheels, and it extends down around the rear side of the wheels in closely spaced relation, the rear and lower edge of the shield or guard being secured, as by welding, to a transverse bar 33 which is attached at its ends to the rear ends of the

downturned frame portions

22 and 23.

A plurality of stripper bars 36, secured at their forward and lower ends to the rear crossbar 6, extend into the spaces between the wheels, as best shown in Figs. 4 to 7, far enough to pass under a ball held between adjacent wheel tires. As the wheels rotate, the stripper bars 36 dislodge the balls from between the wheels, whereupon the balls roll forwardly .by. gravity along the upper side of each stripper bar and into ballreceivin means carried on the frame. Preferably, as best shown in Figs. 1 and 2, such ballreceiving means consists of a pair of rectangular containers 4|, each of which has front and rear flanges adapted to rest on the

crossbars

5 and 6 but, when filled, they may readily be lifted from the machine. For the purpose of deflecting balls on the ground into the spaces between the retrieving wheels, I provide depending deflector bars 42, fixed at their upper ends, as by welding, to the rear crossbar 6. Secured to the forward side at the lower end of each of the deflector bars 32 is a forwardly extending lug 43 which, ;during the passage of the machine over the ground, aids in pushing balls on the ground over into positions where they may be picked up by the wheels 25.

Attention is called to the fact that the balls are engaged by the wheels and the shield so that they are'rolled up between the wheels and shield as-the machine moves forwardly.

The operaticnoi the m a'chin'e of the present invention is-b'eli'eved to beclear from theabcvc description. As'the machineis pulled over the groundpthe -de'fiectors l2, ll3 place the golf balls min a position to pass into the space between adjacent wheels. As the machine passes over the balls, the latter are held between the tirell-lie peripheral portions and the shield-2t and are carried-by the-continued rotation-of the wheels upand -into'the guard or shield "St. The latter thenen ages the balls 'assshowntin Fig. 6, cansing themto roltalong, the wheels embracing the "balls 'until the latter :are brought upwardly to points :wh'erezithey-are removedi'rrom.between the wheelsfby the stripper :bars '36. After being dislodged by :the latter, .the balls roll downwardly :androrwardlyalong:the bars .3 5 and into the container 1 51. .Since :eachside wall of each of 'the'tire-like peripheral portions can be deflected laterally inwardly when a ball .is encountered, independently otthe opposite side wall, .when a ball is 1 held between ;-two adjacent tire portions 2?, it does not interfereyvith another ball being .held bctweenzthezother sideof either of said tire portions :and: the nextradi acent tire portions.

,WhileI havaillustrated'sa part ofa single unit,

it will beunderstoodthat .as. many units may be .used-,'side:by:side, vas are desired. It is customary tomseethree units, side by side, with thirteen wheels, each, :but one person :has purchased rsix unitsiso that-he ma'yrcover approximately twenty feet at a time.

It is ofcourse understood-that the specific description of structure set forth-above .rnay be departed from without departing; from the spirit of this invention asdisclosed in this: specification and as. defined by theappended claims.
