Claims. (Cl. -21) This invention relates to apparatus for cleaning and polishing spherical objects, and more particularly to an improved apparatus for rapidly and efliciently cleaning and polishing bowling balls.

In a machine constructed in accordance with the invention, there are provided two cleaning and polishing brushes which rotatably support a spherical object such as a ball and also clean and polish it. One of the brushes rotates continuously; the other rotates intermittently. As a result; of the continuous rotation of one brush, the object being cleaned and polished is also rotated continuously, but at a slower rate than it is when both brushes are rotating in unison. When the intermittently operated brush is rotated for a predetermined period of time, it turns the rotating ball being cleaned and polished a few degrees, or shifts it relative to the axis of the. continuously driven or rotating brush. Since the intermittently driven brush is operated for a plurality of sequences during each ball cleaning and polishing period,

it will be seen that the surface of each ball subjected all the entire surface of the ball may be completely cleaned and polished.

It is a further object of the invention to provide a novel spherical object cleaning and polishing apparatus having two cylindrical brushes mounted angularly in different planes and wherein one of thebrushes in continu- .ously driven and the other is intermittently driven in order to insure that the entire surface of a spherical article supported by the brushes and rotated thereby will be completely cleaned and polished. I

It is a further object of the invention to provide a ball cleaning and polishing apparatus where two angularly mounted cylindrical brushes coact to support a ball and to effect such movement thereof relative to the two brushes that the entire surface of the ball is cleaned and polished according to a prescribed cleaning and polishing pattern. 7

The invention further consists in the provision of a novel and simple ball cleaning and polishing apparatus wherein two brushes support and clean and polish a ball, and means are included for maintaining a ball to be cleaned properly positioned on the brushes so that the desired cleaning and polishing of the ball will proceed. accoi ding to a prescribed pattern and be completed in predetermined timed cycle of operations.

The invention also consists'in the provision of two coacting elongated cleaning and polishing brushes, which support a ball and demand polish the surface thereof,

'ice

and wherein the ball in continuously rotated at one rate of speed by one of the supporting brushes and at a different rate of speed by the supporting brushes when both brushes are rotating, in order that the entire surface of the ball may be cleaned and polished.

It is an added object of the invention to provide a ballcleaning and polishing apparatus having two opposed elongated ball supporting, cleaning and polishing brushes, one of which is intermittently driven while the other is continuously driven, and ball positioning brushes spaced from the first-named brushes operative to center a ball to be cleaned and polished on the cleaning and polishing brushes in order that, as the result of the continued rotation of one of the brushes, and the controlled intermittent operation of the other, the entire surface of a ball may be cleaned and polished according to a prescribed pattern of operations.

.With these and other objects of the invention not specifically mentioned in view, the invention consists in certain combinations and constructions which are described fully hereinafter, and then set forth in the claims here- ,unto appended.

In the accompanying drawings, which form a part of this specification, and in which like characters of reference indicate the same or like parts:

Figure 1 is a front elevation of the bowling ball cleaning and polishing apparatus with the front cover removed.

Figure 2 is a side elevation of the same with the side cover removed.

Figure 3 is a plan view of the bowling ball cleaning and polishing apparatus with the hinged top cover partly broken away, and a Figure 4 is a wiring diagram illustrating the control circuit of the bowling ball cleaning and polishing apparatus. With reference to the drawings, which illustrate a preferred embodiment of the invention, the bowling ball cleaner and polisher consists of a housing 10 in which are mounted a pair of cylindrical rotating brushes 12 and 14.

ings 20 mounted on a pair of spaced cross-framemembers 22 held by a channel frame 23. Mounted on one end of shaft 18 is a pulley 24 which by means of a suitable belt 26 is continuously driven by pulley 28 secured to shaft 30 of split phase motor 32 mounted on platform 34 of housing 10.

Cylindrical brush 14, designated the pattern brush, is adjustably secured on an angularly mounted shaft '36. This shaft is rotatably supported at its ends by suitable bearings 38. One bearing 38 is secured to bracket 40 attached to one of the cross frames 20. The other hearing 38 is fastened to a block 42 secured to angularly mounted bar 44 attached to channel frames 23. Secured to one end of shaft 36 is a pulley 46 which by means of a suitable belt 48, is driven intermittently from pulley 50 mounted on shaft 52 of a capacitor start motor 54. This motor as described more in detail hereinafter, is intermittently and automatically turned on for suitable periods of time, say 2 seconds, and 3 /2 seconds off throughout the ball cleaning and polishing cycle, which may be of any suitable duration, such for example as two minutes.

Brushes 12 and 14 can be formed of any suitable materials orcombination thereof as long as they have the capability of supporting a ball, and, can exert sutficient cleaning and polishing action necessary to clean and polish a ball in a minimum of time. It has been found 'that brushes composed of a combination of vegetable drive or cleaning motor.

' 2,980,936 A I .T

The cycle timing mechanism for the apparatus is located in control box 56 secured to frame 58 within housing 10. Capacitor motor-'54 is mounted on an angle block 60 secured to platform 34 in the bottom of housing- 10. This housing is =mounted on suitable casters orfrollers which allow the apparatus to be moved around as desired in a bowling alley. The top portion of housing 1t) is provided with a plate 62, the center portion of which has an opening 64, preferably circular, employed for the purpose of allowing a bowling ballB to be placed correctly on the cylindrical brushes 12 and '14 and at the same time, providing means for maintaining the ball in centered position during cleaning and polishing operations. Plate 62, as shown, is suitably secured to the inner walls of housing 10.

Circular opening 64 also is provided with two re'ctangu- 1 lar cut-outs 66 which are 180 opposed from each other. These cut-outs form the openings for two quarter circular downward projecting cowl-shaped guards 68 provided for the purpose of permitting the ball to be placed on the brushes 12 and 14 and at the same time providing means to prevent the hands of the person who inserts the ball in opening 64 from coming in contact with the mechanism and thus constituting a safety guard. The adjustable mounting of brushes 12 and 14 on their respective shafts 18 and 36 insures long operating life. When the cleaning 'eflici'e'ncy of brushes 1'2 and 14 has decreased due to use, it is only necessary to loosen the set screws securing them to their operating shafts and either slide one or both brushes ashort distance along its shaft, or remove one or both brushes andtreverse them on their shafts and then tighten the set screws; This adjustment provides a new contact area on the brushes exposed to balls to be cleaned and polished.

In order to assist in maintaining a ball centered on the cleaning brushes during the cleaning and polishing operations and prevent the ball from contacting the rim of circular opening 64 in plate '62, the latter is provided with two bumper brushes 70 which are mounted opposite each other and extend horizontally partway in the opening 64. Each bumper brush 70 is heldby a suitable mounting bracket 72 secured to the underside of plate 62 so that said brushes may easily be adjusted or replaced in case of wear.

The top portion of housing ltlconsists of a removable dome 74 which rests on the housing and is interlocked therewith by means of a pair 'of upright studs 76 proas a Hansen Mfg. Co., Cycle Timer," model 610 (Fig. 4), adjacent which are mounted two cam operated switches 90 and 92. Switchr-90 is the pattern motor control switch and is actuated by means of a phenolic condensation product and over cam 94 cut in a saw tooth fashion. Cam 94 is mounted on output shaft 96 of timing motor 88 by means of set srew-98. The latter, provided with a rounded head, is long enough so that the head contacts and actuates the switch 9 2 once in' each revolution of timer shaft 96. Switch 92 controls the starting and stopping of the'operating cycle of cleaning motor 32.

With reference to the Wiring diagram shown inFig. 4 of the drawings the sequence of operation of the ball cleaner and polisher is as follows:

After a ball B is placed on the brushes 12 and 14 in the machine the operator'closes the 'hinge mounted cover 80 which as mentioned heretofore causes switch 84 to be closed by lug 82 mounted inside cover 80. In order to start the machine the operator then depresses start button -100"which isconveniently secured'to the exterior of dome 74. Start button switch 100, may be replaced by acoin operated switch if so desired.

The momentary closing of-starter switch 100 permits 'currentto flowthrough the closed contactor arm 102 of switch 92 and cause the energization of relay 86 which, after the release of button 100, is held in hy-means "of its own contacts 104. Since "the'energiZation of relay 86'also cause'd the cIo'sing-of relay contacts'106 and I switch 84 was closed when the cover 80 w'asclosed by jecting upwardly from the frame 23. Thesestuds engage with suitable holes in a pair of brackets 78 secured to the inner walls of dome 74. The latter is also provided with a curved hinge mounted plastic glass cover 80 which is lifted to insert the ball into the machine, but due to its transparency, permits viewing of the cleaning and polishing process. Cover 80 is provided with a lug 82 which, when "cover plate 80is. closed, depresses a switch button 84 which'clo'ses the operating circuit :and starts the machine. When cover 80 is open, switch 84 is inoperative and the machine. cannot be started until it is closed again.

As mentioned heretofore the apparatus embodying the invention is provided WithltWO motors 32 and 54. Motor 32 preferably is a split phase and is referred to as the circuit of the machine in "such manner as to run continuously during the selected cleaning cycle which is usually about two minutes Motor 54 preferably is a capacitor start motor :andis referred to as the pattern motor. 'Motor '54 isintermittentl-y driven during the cleaning cycle. .As an example of its operation 'itzmay be turned on for 2 :seconds, and off for 3% lseconds throughout the selected cleaning cycle.

The cycle. timing mechanismzwhich controls S'the cleaning and polishing operation of brushes 12 and 141s mounted in control box '56 mentioned hereinabiove. The

"components enclosed in box 56 consist of "a holdain relay 86 and a suitable conventional timingmotorSS, *such Itis connected in the operating I the operator, current now flows to the cleaning motor 32 which starts running and thus-drives cleaning brush 12. Closed switch 84 also permits current to flow to the timing motor 88 which starts it: The starting of timing motor 88 effects the rotation of cam 94 whi'chin turn through arm 1'08 opensand'closesswitch 90 which contrek the starting and stopping of pattern motor 54.

Inorder to prevent the cleaning and pattern motors 32 and '54, respectively, from starting at the same time which would-cause an excessive inrush of current, one of the teeth of saw tooth shaped cam 94 is' removed so that closing of switch 90 and thus starting of pattern motor 54 is' delayed for a suitable period, say about six seconds. The rotation of cam 94 also causes the head of the set screws '98 on cam 94 to disengage from "arm of switch 92 causing contactor arm 102 to open and interrupt the current flow to relay 86, which at the same time another contactor' arm 112 in switch-'92 closes and permits current to flow 'througha relay-bypass circuit directly to motors: The opening of contactor arm 102 eifects the disenergization of relay 86 and thesawtoothed cam .94 causes the intermittent starting and stopping ofLthe pattern motor 54. When,;after one revolutionof cam 94 the head of set screw '98 contacts and depressesJswitch arm 110 of switch 92 contactorarm 112 in swith92 opens and interrupts all current how to the motors and thus effects the stopping of the machine.

In order to provide means to enable the operator to run the machine continuously,theilatter. is provided with 'a switch 114 which may be turnedfbyakey 116 (Fig. 2) and thus supply operating current even Iifth'e' .cover 80 and cover switch 84,.are open.

It will be a parent that in an apparatus embodying the invention we have provided va novel. method of. cleaning and polishing spherical objects, such as bowling balls, wherein the object isplaced on two supporting cleaning and polishing brushes and one brush islro'tated continuouslywhi-le the other is. rotated intermittently in the opposite ldirectionto lprogressiv'e'lyclean and polish the entire surface of the .object in accordancewith a timed program of.operation.-
