ACCESSORY FOR GAME APPARATUS Filed Feb. 23, 1942 BY//m Patented Apr. 27, 1943 ACCESSORY FOR GAME APPARATUS Harry E. Williams and Lyndon A. Durant, Chicago, Ill.
Application February 23, 1942, Serial No. 431,916
This invention relates to game apparatus and more particularly to an accessory for game apparatus and has as its principal object the provision of such an accessory which will be simple in construction, economical in manufacture and highly efcient in use.
It is an object of this invention to provide a n ovel ball objective for game apparatus which ball objective will be adapted to progressively advance playing pieces in accordance with the at tainment of such objective.
Another object of this invention is the provision of a unit for advancing balls from one trap to another down an inclined play board.
Still another object of our invention is the provision of a plurality of ball traps in alignment and adapted to coact with balls played into such traps for ejecting the balls therefrom.
Other objects and advantages of the present invention reside in certain novel details and improvements in construction as will become apparent in the following description read in the light of the annexed drawing in which:
Fig. l is a fragmentary perspective View of an inclined playing board embodying the present invention;
Fig. 2 is a fragment-ary plan view of the same;
Fig. 3 is a longitudinal sectional detail view through the inclined playing board of Figs. l and 2;
' Fig. 4 is a fragmentary bottom plan View of the under side of the play board as seen substantially along line 4-4 in Fig. 3; and
Fig. 5 is a schematic wiring diagram of an electrical circuit embodied in our invention.
The present invention is best adapted for use in ball rolling games, particularly the type known as bagatelle or pin ball games in which balls are adapted to be projected onto the upper end of an inclined play board for gravitation thereover. Such an inclined play board is indicated at Ill and includes a plurality of ball objectives in the form of apertures II cut into the board. In the present instance two of such ball objectives are shown in alignment along the inclined board Ill, it being understood that two or more of such ball objectives may be employed in carrying out the purpose of our invention.
In the playing of games of this type, balls are entrapped in the apertures II and are normally held therein until liberated by some release or resetttting means at the commencement of a new game. The accessory which comprises our invention is adapted for such purpose and in addition thereto is constructed to automatically eject balls entrapped in certain ball apertures for further advancement along the inclined play board during the course of a normal play. This accessory is generally indicated at I2 and inH cludes a strap of metal I3 forming a main carriage for our new unit. This strap I3 is adapted to be fastened to the underside of the board lil in alignment with the aforementioned `aligned apertures I I thus providing a oor for each aperture upon which trapped balls are adapted to rest. An elongated slot I4 is formed in the strap I3 along a line extending from center to center of each aperture II. An ejector member I5 is pivotally arranged as at I6 adjacent each aperture II and such members I5 are in the form of Segments having a pusher nger I'I formed at the edge normally extending through the slot I4 and into the aperture II. The ejector members I5 may vary in number corresponding to the number of apertures II and such members I5 in numbers are connected in tandem by means of a connecting rod i8 having pivotal connection with each of said members I 5 at their lowermost extremity as at I9. A spring 20 is connected t0 the rod I8 and also to a fixed anchorage 2l formed as a part of the carriage I3 in such a manner as to maintain all of the ejector members in normal position so that each aperture is adapted to receive a ball as shown in Fig. 3.
A motivating means in the form of an electroe magnetic solenoid 22 is arranged on a suspended ledge 23 formed on the carriage I3. This soienoid 22 includes an armature 24 arranged for movement within a coil 25 and in a plane parallel to the alignment of the ejector members I5. A link 23 has pivotal connection as at 2l with the armature 24 and has its opposite end pivotaliy connected as at 28 with the rod I8. The arrangement is such that the tandemed members I5 and rod I8 through link 26 are moved in unison by the armature 24 when the coil 25 is energized in a manner later t-o be explained, Also the spring 20 effects return of the tandemed members I5 and armature 24 when the magnetic influence of the coil 25 ceases.
Means for energizing the coil 25 for magnetically attracting the 4armature 24 comprises a circuit 29 including a source of electrical energy 30 having its ground connected to the ground pole of the coil 25 and its positive side connected by a conductor 3| with a plurality of switches 32 connected in series so that each of said switches 32 are required to be closed in order to supply current valong a conductor member 33 to the positive pole of the coil 25. There are a number of such switches 32 corresponding to the number of ball apertures Il, there being one of such switches 32 associated with each aperture. These switches 32 are a pair of resilient leaf spring contact elements 3B arranged with the uppermost element 35 nearest the underside of the ball apertures I I. Each of the upper elements 35 carries an insulating button 36 which extends through a slot 31 formed in the strip I3 so as to dispose such button 36 up in-to the ball trap formed by the aperture I I.
As is seen in Fig. 3 when a ball such as the ball 38 is entrapped in an aperture II, the Weight of such ball 38 will bear down upon the button 36 and fiex the uppermost contact element into contact with the lowermost element, thus completing circuit through the switch 32 of which they are a part. It is apparent that when a ball is entrapped in each of the apertures II, all of the switches 32 will be in circuit completing condition, whereupon the coil 25 will become energized.
Energization of the coil 25 attracts the armature 24 to the right (Fig. 3) and consequently draws the link 26 and rod I8 into dotted line position against the action of spring 20. Such action of the rod I8 causes the tandemed ejector members I to swing in unison upon their pivot mountings I 6 and urges the nose portions I1 into engagement with the entrapped balls 38 raising these balls out of the apertures in a direction for movement down the inclined board I0. The ball ejected from the aperture disposed lowest along the inclined board will be free to gravitate down therefrom while balls ejected from apertures above such point will be disposed to gravitate into the next lowest succeeding aperture. balls are thus displaced from the apertures, the series circuit through the switches 32 is broken and the coil deenergized, thus releasing the segments I5, rod I8 and armature 24 for return to normal position by action of the spring 20.
An auxiliary circuit 40 is provided to by-pass the normal playing circuit 29 and this auxiliary circuit includes a switch 4I controlled by 'a hand operated instrument in the form of a push button or the like for evacuating the apertures upon the playboard to condition the game for a new game.
While we have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation and mcdication without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details of constructions set forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.
