GOLF` BALL RETRIEVING MACHINE Leslie Woodall, Windsor, Ontario, Canada Application August 19, 1953, Serial No. 375,254
3 Claims. (Cl. 214-356) This invention relates to golf driving range equipment and, in particular, to golf ball retrieving machines.
Golf driving ranges, where golfers practice their driving strokes, inthe course of such practice receive hundreds of golf balls which are driven out into the grass of the range to widely scattered locations. From time to time it becomes necessary to pick up these golf balls and return them to the tees for reuse. The problem of picking up this enormous number of widely-scattered golf balls is complicated by the fact that there are two sizes of golf balls still in use upon such rangesthe older and now superseded 1.62 golf ball and the newer and larger 1.68 golf ball which has replaced it in competition. This problem is still further complicated by the fact that some balls become knocked out of round. It is expensive for operators of such ranges to replace all of the older and smaller golf balls with the newer and larger ones, especially since such balls are subjected to such rough treatment that it is costly enough even when using balls of both sizes.
Golf ball retrieving machines hitherto devised have frequently been the cause of damaging many of the golf balls while they were being picked up, and such prior machines have been incapable of satisfactorily picking up both sizes of balls or balls which are out of round. Certain prior machines, moreover, have caused damage to the turf when turning corners while others have suffered from iniiexibility and inadaptability to both small and large driving ranges.
One object of the present invention is to provide a golf ball retrieving machine which is adapted to rapidly and eiciently retrieve balls of both sizes currently in use, even when both sizes are distributed indiscriminately over the range.
Another object is to provide a golf ball retrieving machine wherein the balls are retrieved by resiliently mounted discs which not only pick up both sizes of ball and balls which are out of round, but also by their resilient mounting firmly grip the balls as well as yielding sufficiently to prevent damage to the ball if a ball is encountered accidentally directly under one of the discs.
Another object is to provide a golf ball retrieving machine which turns corners easily without digging up the turf and which is also easily backed. Y
Another object is to provide a golf ball retrieving machine which is assembled in independent units connected to one another so that a small golf driving range may use only one or two units, whereas a large one can assemble as many as five units side by side in one machine, the different units being linked together by parallel links which enable them to rise and fall independently so as to adjust themselves to irregularities in the terrain.
Other objects and advantages of the invention will become apparent during the course of the following description of the accompanying drawings, wherein:
Figure 1 is a top plan view of one of the self-contained units of a golf ball retrieving machine, according to one sited? States Patent() nel members 40 by supplemental channel members 48.
n consists of a central anged hub 60 bored as at 62 to form of the present invention, with a removable golf ball receiving container indicated in dotted lines;
Figure 2 is a side elevation of the golf ball retrieving unit of Figure 1, with the removable golf ball receiving container similarly shown in dotted lines;
Figure 3 is an enlarged fragmentary vertical section through a pair of the golf ball retrieving discs and the ball guide between them, taken along the line 3-3 in Figure 1; and
Figure 4 is a top plan view of a complete machine consisting of five interlinked units of the type shown in Figures 1 and 2.
Referring to the drawings in detail, Figure 4 shows a golf ball retrieving machine, generally designated 10, as consisting of a plurality of identical but independent golf ball retrieving units, generally designated 12. Five such units are shown for purposes of illustration, but it will be self-evident and distinctly understood that a greater or lesser number may be used depending upon the size of the range and the volume of golf balls requiring retrieving. Moreover, the machine may be started with one or two units, and other units 12 may be added from time to time as the range increases in size or use or becomes financially better able to afford a larger machine. The central unit 12 isconnected by a main draw bar 14 to a tractor or other towing machine, the draw bar 14 having a hook or right-angle bend 16 at its rearward end and a coupling eye 18 at its forward end.
Also welded or otherwise secured to the forward end of the main draw bar 14 is a coupling plate 20 having spaced multiple holes 22 therein, these holes being engaged by the forward bent ends 24 of secondary draw bars 26, the rearward bent ends 2S of which are connected to the outlying units 12 in a similar manner to the central or main draw bar 14, as described below in connection with the description of the individual units 12. The individual units 12 are interconnected laterally by floating links 30 secured by pivot bolts or pivot pins 32 at their opposite ends to the respective adjacent units, which are separated laterally a slight distance from one another to enable relative rise and fall of one unit relatively to its neighboring unit or units without flashing or conflicting with one another.
Each machine unit 12 consists of a rectangular main frame 34 composed of front and rear channel members 36 and 38 interconnected by side channel members 40. Intermediate their opposite ends, the side channel members 40 are interconnected by an intermediate cross channel member 42. The forward and intermediate cross channel members 36 and 42 are interconnected by a central longitudinal channel member 44 whereas the intermediate and rear cross channel members 42 and 38 are similarly interconnected by slightly spaced parallel channel members 46. Similarly, the outer ends of the same cross channel members 42 and 38 are interconnected adjacent the chan- These various frame members 36 to 48 are preferably secured to one another by welding in order to form the main frame 34.
Bolted or otherwise secured to the channel members 46 and 48 and depending therefrom are two pairs of aligned journal bearings or shaft hangers 50 in which two coaxial but longitudinally spaced shafts 52 are rotatably mounted. Secured at intervals along each shaft unit 52 are axially spaced sets or pairs, collecttively designated 54, of ball pickup wheels 56 and 58 respectively. The wheels 56 and 58 are similar in construction to one another but face in opposite directions (Figure 3) so that a single description and a single set of reference numerals will suce for both.
