, ERNEST MEIERJOHAN ATTORNEY GOLF BALLDISPENSER OR THE LIKE Ernest Meierjohan, 3342'Hanna, Cincinnati, Ohio Filed Sept. 3, 1964, Ser. No. 394,185 12 Claims. (Cl. 221205) example, the dispenser may serve as a reservoir into which golf balls may be dumped at random, vibrated to assure an even flow, and fed promptly to a supply conduit or station at which the balls may be presented in uninterrupted succession, for use as driving practice balls at a driving range or the like;

In connection with any device of the character stated, profitable operation requires that the balls be supplied to the user or player without waste of time, and certainly without the annoyance of failure of the ball feed mechanism. In the past, efiorts to mechanically feed golf balls from a hopper to the hands of a player, or to a T, encountered various difficulties which, as I have discovered, resulted from a peculiar tendency of the balls to cling to one another and resist rearrangement when in contact with one another within a hopper. Thus, in the absence of an eifective form of agitation within the hopper, the balls contained therein would not readily rearrange themselves to induce dependable flow of balls from the hopper to a delivery chute or conduit leading to the players station. In fact, it was common for the balls to form one or more arches within the hopper, as indicated at X upon FIG. 1, to block gravitation of the balls toward the hopper discharge port, and thereby defeat the objective of constantly and dependably maintaining a supply of balls accessible to the player or user. a

An object of the present invention is to provide a dispenser of balls or spherical objects, which will feed balls from a hopper or reservoir to a delivery port, with unfailing dependability and despatch.

Another object is to provide apparatus for the purpose stated, which is simple and foolproof, and which requires no attention in the course of operation, to maintain an adequate supply of balls at its delivery station,

A further object of the invention is to provide an improved ball dispenser which may be quickly and easily charged with balls at any time during its operating period, and which will arrange and feed the balls fashion without damaging the balls.

The foregoing and other objects are attained by the means described herein and illustrated upon the accompanying drawings, in which:

FIG. 1 is a vertical cross-sectional view of the improved ball dispenser, showing a quantity of balls supported within the hopper portion thereof, the balls having been poured into the hopper portion from a bucket or other container.

FIG. 2 is a perspective view of the ball dispenser, part of a sidewall being broken away to expose interior construction.

FIG. 3 is a fragmentary enlarged cross-section taken on line 3-3 of FIG. 1.

FIGS. 4, 5 and 6, are enlarged detail views of a ball feed wheel and associated agitator, these being illustrated in various phases of operation in the several views.

With particular reference to FIGS. 1 and 2, the numeral denotes a housing having side, end, and

bottom walls

12, 14 and 16 respectively. Walls 12 preferably are in orderly United States Patent 0 spaced apart a distance slightly in excess of the diameter of a ball B, FIG. 3. In a preferred embodiment of the invention, the upper portion of housing 10 is flared outwardly to provide an enlarged funnel-like throat 20 3,248,008 Patented Apr. 26, 1966 facilitating pouring of balls into the housing from a bucket or other container. A lid or door 22 suitably hinged upon the housing at 24, may control access to the interior of the housing.

At a lower corner of housing 10, a ball delivery port 26 may direct balls from the housing to a delivery conduit or tube 28, which leads to a remote players station or possibly to a T that sets up a ball for play. Balls fed into the delivery conduit or tube 28 may accumulate therein, one behind another, so that a continuous succession of balls is presented at the players station, preferably by gravity advancement. Means are provided for adequately feeding balls to tube 28 as balls are removed therefrom at the players station.

The ball feed may comprise a motor-driven feed wheel 30, and a cooperating vibratory shelf or inclined support 32 which carries the weight of most of the balls in housing 10. Shelf 32 may consist of an elongate strip of metal or other suitable material, having a rear end 34 mounted upon an end wall 14 of the housing, and a forward terminal end 36 projecting toward and terminating short of the opposite end wall of the housing. The end 34 may be resilient at the location 38, or may be otherwise adapted,-to hinge the shelf for movement of terminal end 36 in a vertical plane. Preferably, the shelf is yieldingly biased rather strongly toward a stop 40 with a forceful snap action and thereby re-arrange the balls above it to break any cohesion or arching tendency such as is indicated at X, FIG. 1.

Shelf 32 may carry .a depending reinforcing rib 42 to stiffen the shelf between hinge portion 38 and its terminal end 36. The width of the shelf is less than the distance between the side walls 12 of the housing, so that the shelf may move freely between the side walls. Spacers as indicated at 44 may be employed to maintain a fixed spacing of the housing side walls from one another. In the example illustrated, the numerals 46 denote rivets or equivalent fasteners for mounting the shelf upon housing wall 14.

The terminal end 36 of shelf 32 approaches, but does not reach,-that end wall of the housing which includes the port 26. Intermediate said end wall and the terminal end of the shelf, the housing supports a transverse rotary shaft 48 disposed at an elevation lower than the shelf end 36, and upon said shaft is fixed the feed wheel 30. A motor 50 disposed exteriorly of the housing, drives shaft 48 and wheel 30 constantly at slow speed, in the direction indicated by arrow'52.

Feed wheel 30 may be considered a star wheel in the sense that it includes a plurality of peripheral lobes 54 separated from one another by valleys, recesses or depressions 56. The valleys, recesses or depression-s 56 may be formed on an arc corresponding substantially with the arcuacy of a portion of ball B (see FIG. 4); As the feed wheel rotates, the lobes thereof agitate the balls in an upward direction so as to preclude jamming of the balls against the end wall of housing 10. The halls, however, are free to gravitate past the feed wheel and into delivery port 26; since the lobes of the feed wheel are spaced from the adjacent end wall 14 of the housing a distance greater than the diameter of a ball.

Means are provided for imparting to shelf 32 a succession of forceful snap actions in a downward direction, to break any cohesion or arching tendency of the balls within the hopper capable of interrupting a steady flow of balls past the feed wheel and into the delivery port. Such means may be activated by the feed wheel or its drive shaft, and may comprise a plurality of shelf lifters each in the form of a lever 60 pivoted upon the feed wheel radially outwardly from shaft 48. Each lever has an inner end portion 61 pivoted at 62 upon the feed wheel, and the outer end of each lever may carry an anti-friction roller 64 adapted to contact and lift an arcuate cam follower 66 connected to the shelf 32 near its terminal end 36 by means of an extension finger 32a secured at one end to the shelf 32 and extending forwardly therefrom and having the cam follower fixed to its other end.

In FIG. 6, none of the lifters 60 are in contact with cam follower 66, wherefore shelf 32 is disposed in the fully lowered or home position against stop 40. It may be noted that lifter 60 at the left of shaft 48 in FIG. 6, extends radially and rests upon a stop 68 fixed upon wheel 30. Clockwise rotation of wheel 30 will bring the roller cam-ming 64 to the FIG. 4 position, at which roller 64 strikes the leading edge 70 of cam follower 66, thereby to elevate the shelf 32 relative to stop 40 and cause the shelf to lift many of the balls within housing 10.

Continued rotation of feed wheel 30 places the lifter roller 64 at the FIG. 5 position, where the roller is about to leave the trailing end 72 of cam follower 66. As the roller passes off the cam follower end 72, it will suddenly drop about pivot 62 to the broken line position 74, permitting shelf 32 to snap down to home position as shown by broken lines in FIG. 5, the snap action being augmented by the spring section 38 of the shelf mounting. The displaced lifter, having dropped to the inoperative position 74, is stopped against the abutment 68. Rotation of the lifter about its pivot 62 may be limited to about 90 degfees, by the stop or abutment 68.

As the feed wheel 30 continues to rotate, lifter 60 will be picked up by stop 68" for restoring the lifter to radial position (see lifter 60 at the left of shaft 48 in FIGS. 5 and 6), thereby placing the lifter in operative position to again actuate the cam follower 66.

From the foregoing, it is apparent that a snap-action movement is imparted to shelf 32, following each traverse of cam 66 by a lifter 60. The number of lifters may be varied, and coordinated with the speed of rotation of feed wheel 30, as desired. It is important, however, that the lifters leave the cam suddenly at, the trailing end 72 in order to produce a form of agitation capable of breaking.

the inherent arching and cohering tendency of the ball compilation. It is desirable also that the shelf be returned to home position by spring action or other forceful means,

the shelf end 36 and feed Wheel 30 during the. operating period. The bafile slopes from the housing end Wall downwardly toward the shelf, and has a free end 80 which is spaced from the shelf sutficiently to permit passage of several courses of balls to the restricted zone 78. By this means, the feed wheel and the terminal end 36 of shelf 32 are relieved of the strain of agitating and displacing the weight of the many balls within the hopper during rotation of the feed wheel, and the freedom of ball movement provided by zone 78 assures an easy flow of balls past the feed wheel and into delivery port 26. The arrangement definitely eliminates the arching depicted at X in FIG. 1 while the apparatus is in operation.

In FIG. 3, the numeral 80 indicates a bearing carried by one of the housing side walls, to support an end of drive shaft 48. Such hearing may or may not be needed, depending upon the adequacy of the drive motor to support the feed wheel without the assistance of exterior shaft bearings, as will be understood. The shelf stop or bumper 40 may be formed of rubber or other resilient material, if desired.

It is to be understood that various modifications and changes may be made in the structural details of the device,
