July 1, 1947. A. SHULKIN MINIATURE PINBALL DEVICE F iled Dec. 18, 1944 III/I y WWW Patented July 1, 1947 ant UNITED STATES PATENT ()FFICE 8 Claims.

The present invention relates to pin ball machines and has particular reference to a miniature so-called pocket-sized type such as is believed to be ingenious and, therefore, an innovation in this line of endeavor.

More specifically, I have devised a simple and expedient pin ball game or device of a portable pocket-sized form suuceptible of being carried on ones person for handy and convenient use,

In carrying out a preferred embodiment of the invention, I provide a unique adaptation to the purposes intended, the same being characterized by an obstacle equipped ball receptive playing field, a ball-accommodating and projecting chute and novel spring-returned means coacting with the ball loading end of the chute for effectively projecting said ball.

Another object of the invention has to do with the adoption and use of a single ball, this to provide for simplicity, economy in construction, and ease and fairness in tallying the scores made by the players.

Another phase of the invention, seemingly possessed of newness, is the adoption and use of an appropriately anchored and tensioned fiat spring carrying a trigger at one end, the intermediate reach of the spring being so fashioned and arranged as to coast with short spaced partitions, the latter in conjunction with the coacting portion of the spring defining ball trapping pockets or stalls.

Then too, the bottom of the ball-accommodation obstacle field is contoured with pre-determined declivities r inclined regions coacting and merging with each other to facilitate gravitation of the ball from one end of the field into the stalls and then from the stalls toward the loading end of the ball feeder chute.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a top plan view, with the transparent cover removed, of a miniature pin ball device constructed in accordance with the specific principles of the instant invention.

Figure 2 is a fragmentary top plan view of the lower or inner end portion of the device, the cover panel being in place and the scoring legends painted or otherwise arranged on the underside thereof.

Figure 3 is a transverse section on the plane of the line 33 of Figure 1, looking in the direction of the arrows.

Figure 4 is a longitudinal sectional View taken centrally on the plane of the line 4-43 of Figure 1, also looking in the direction of the arrows.

Figure 5 is a fragmentary plan view of the lower end portion of the device showing the ball propulsion spring flexed to receive the ball and to facilitate placing same in entrance end of the chute.

The main body of the device, which is preferably rectangular in form and about the size illustrated in the drawing, is cast or otherwise formed from metal, plastic, or the like. The body as a unit, is denoted by the numeral 5. The top side thereof is provided with a recess defining an upstanding marginal rim and the upper surface portion 6 of said rim has a marginal groove 1 which defines a ledge for properly seating the glass, plastic or other transparent panel 8. On one side, as shown in Figure 1, is a longitudinal properly positioned and proportioned rib 9 which coacts with the adjacent portion of the rim in defining a ball runway or chute Hi this to accommodate the projectible ball II. The outer discharge end thereof is deflected laterally as at E2 and coacts with the arcuate ball guiding abutment IS. The numeral I4 designates a diamond-shaped boss which is centrally arranged in respect to the longitudinal dimension of the ball-accommodation field and other associated features. This is one of the socalled obstacles. The other obstacles are in the form of studs or pins l5 and these are arranged at pre-determined points by the manufacturer. The numeral l6 designates a penalty line which will be later covered. Adjacent the left hand corner area is a suitably shaped rubber bumper or buffer ii. The numeral I8 designates an insert or block having a longitudinally bowed edge H) which serves as a spring flexing eye gage and stop and this has its left hand end formed with an L-shaped notch which is spaced from adjacent surfaces of the rim to provide a keeper for the coacting end of the spring. The spring, as a unit, is of general U-shaped form and has one end of L-shaped form, the portions 20 and 2| thereof being anchored in the L-shaped keeper notch defined between said insert block l8 and adjacent wall portions of the rim of the body. The free opposite end of the spring is laterally directed as at 22 to define a trigger and the free terminal of this has a suit' able lateral trip 23. The trip equipped end extends through an accommodation kerf 24 in the right hand corner portion of the body. The intermediate reach portion 25 of the spring bridges the lower half portion of the playing field. It is of sufiicient resiliency to provide the ball propulsion requirements. In addition, it constitutes a gatej as is evident. That is to say, the trigger-equipped end bridges the loading end of the chute It to serve as a projector for the ball. The intermediate or reach portion 25 bears at one end against the buffer l1 and then bridges, in slight spaced relation, the

spaced parallel partitions. I provide four of hose in order to define five ball-receptive and scoring stalls or pockets. It is also to be noted that the intermediate portion 25 of the spring is slightly diagonal in respect to the longitudinal dimension of the body. Moreover, the dividers 26, which are of sufiicient height, incline from right to left, this for the purpose of facilitating the return of the ball into the ball-return area where it is retrieved and delivered into said chute. The main ball-coursing surface 2"! is inclined from the abutment I3- tovvard the stalls. This decline is brought out in Figure 4. Then, the ball-return area has its surface 28 inclined from left to right. Or, in other words, we have a longitudinal inclination 21 merging into a coacting transverse inclination 28," these coacting Withthe ball-receivingpockets to facilitatereleasing of the balls after they have been trapped. There is sufficient clearance between the partitions 128 and the stop. surface l9 to permit the ball to clear out of any one of the pockets and 'to roll and follow down on the portion 22 of the spring, whereby to permit it to be properly located for the next shot.

' The underside of the cover 8 is provided with suitably designedand painted ball-scoring indicators 29, of which there are five in general practice. These register with the stalls or pockets. v

The ball propulsion element is preferably a one-piece springfserving atthe same time as aguard'o'r gate for score denoting stalls. Same is to be made out of metal spring, rubber band, string, gut string, plasticwooden spring, push plu'nger, snap plunger, etc, all of which serve the stated double functionj The purpose is. to. achieve the highest score by skillful shooting of the ball from the loading compartment of 'thechute into the field with obstacles and then the placing of theball into the score stalls orpocketsl The'stalls are arranged in the following fashion:

#1 stall scores Loss #2. scores 500.

#3 scores 300 #4 scores 1001". #5.scores Win By virtue of the placement of obstacles in the playfield, the win score i's'the most difficult to achieve; and; could be done consistently only by a very delicate shot to propelthe ball. Such adelicate shot will propel'the ball against the Diamond obstacle, then bounceofi and follow a direct course downward between theobstacle Pins and the side of the Chute right down into; the Win stall. Conversely, the Loss stall is arranged in relation to the obstacles in the playfieldin such: a way that in careless playing, it is the easiest compartment to place theballin. The rest of the Score Stalls are distributed about evenly] About three-quarters up the length of the Chute, there is a penalty line. This is provided to penalizeoverlydelicate shooting; the penalty shots considered to be'those that pass above the; penalty lineinside of the chute but are not, strong enough to reach. out into. the obstacle playfield and consequently roll back, into the loading compartmen The invention is in effect, a, portable .gamepiece. in the form of a pin; ball machine. In Dlaged upona flat table such, as a, surfaceand fo 1 this reason thebottorn or underside of the pocket-sized miniaturev use it is preferably.

body is perfectly flat to insure that it will be level and that fairness of play will exist among competitive players. Of course, certain players will agree to use the device while held in the palm of the hand but is primarily intended to sit fiat on a stationary surface.

An article of this type can be made, in actual practice, as a belt buckle, or, can be used in connection with a wrist-band or bracelet, as a sort of an ornament. In fact, it might be providedon the back with a pin to be employed as a sort of lapel ornament. These are, however, incidental phases of the invention.

Due to the size of the device herein illustrated it is referred to as a miniature pin ball device. The latter expression is used advisedly in contrast to the expression machine inasmuch as the same feature could be employed a full sized machine. By the same token an article of this type, being somewhat toy-like in form could, as before implied, be covered as a sort of a game piece. I simply desire to biting attention to these factors in order to assist the reader in interpreting the nature of the invention, the scope and the delinitions thereof in the claims.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size and arrangement of details coming within the field. of invention claimed may be resorted to in actual practice, if desired.
