ArrAaA'ros non use IN PLAYING GAMES or THE ROULETTE TYPE.
Be it known that Application filedFebruary 27, 1923.
concern: I, J orrn J AMES JARvIs,
a subject of the King of Great Britain and Ireland, residing at 24 Ranelagh Barnes, in the county'of Surrey,
have invented new and usefuhImprovements in Apparatus for Use 111 Play ng Games of the Roulette 'Type,

Apparatus adapt ed for use in carrying my present invention into efiect is illustrated in whereof Fig. 1 is a plan view, a transverse section.

The-table a of the game apparatus is subdivided, as' shewn in into variously coloured segments, turn are subdivided by arcs struckw1th various radii; each sui tablynumbcred or which n such sub-division being otherwise distinguished.
The table, thus. coloured and marked "off,

In a central orifice formed'in thetable a is freely this stem is fitted mounted a'tubula'r stem and on a loose sleeve 6 surthe stem isa pinion an'eccentrically mounted pinion g,

The inclined floor m is attached to the upper sleeve (Z and derives rotative motion from the tubular stem j, the latter being in connection with the motor-spindle Z, preferably by means of a spring clip a, such as shown on an enlarged scale in Fig.4. The inclined floor m is formed at one point'in its periphery with a depression m such as shewn inrFig. l, which serves as a ball-chute on theorifice Z in the side of the receptacle 7c. Beneath the ball-receptacle Z is arranged a circular plate 0 which serves to convey the balls, as they issue from arriving opposite the orifice Z, to the outer portion of the table.
Above the gear tram is arranged a platea (shewn in plan in Fig. 5) the sides of traverses thefloor of a cup shaped freely mounted,-upo.u a light feather spring which are turned down to rest upon the table or plate a and are formed with ears a which passthrough slots in the plate a and arethen turned laterally to engage with the under side thereof; being thereby securely "fastened together. to afford a bearing for the upper extremity of the stud on which the cccentrically disposed gear wheelsg, h are mounted. 7 From the foregoing it will beunderstood that the clip a, when engaged with the motor-spindle Z, drives the tubular stem. This stem drives the pinion 6,,and, through the eccentrically mounted pinions h and g, the sleeve 0, whence the ball-receptacle l derives rotative motion by frictional contact withfthe shoulder 6 upon which it'rests. The inclined floor m of the ball-receptacle is attached to the upper sleeve 01; derives the two plates (1, a,
rotative motionby reason of its resting upon the upper extremity of the sleeve 6, and consequently is also driven frictionally.
The legs X are capable of attachment to the edge of the table or plate a at different distances from the centre with a view to adapting the apparatus to gramophone tables of different diameters. As may be seen in Fig. 2, the horizontally projecting arm X of the leg X is formed with two folded loops, in either of which the edge of the table or plate a may be engaged.
When working the apparatus from the spindle of an ordinary gramophone, it is desirable to effect a considerable increase in the speed of rotation of the ball-receptacle 7c in relation to the said spindle. The pair of spur wheels i [L are accordingly propoi tioned to'eli eet .one increase in speed, whilst the pair o tgear .wheels 9 f are so proportioned as to effect a further increase. The former pair consistv moreover of eccentric and elliptical wheels, which have the further effect of varyinguthe speed at; diiierent porions of their rotation; it being desirable to produce irregularity, rather than regularity, in the speed of rotation of the ball-receptacle 7a in addition, to the irregularities which occur owing to slip taking place in the driving parts; the drive being merely dependent on friction of a very moderate character.
It will moreover be understood that, owing to slip. at the spring disposed between the second and third pinions of the geartrain, when such spring is employed, or to slip between the under surface of the plate (a and the boss on which it rests, the relative rotative speeds of the ball-receptacle and of the inclined floor therein arranged frequently vary; with the eii'ect that the interrails of time between the successive periods of coincidence between the discharge point 221 in the revolving floor and the orifice Z in the ballreceptacle undergo constant variation. The form of the orifice Z' which I have found best adapted to prevent the balls jamming therein is shewn in Fig.
lVith a view to further increasing the irregularity with which the balls are delivered from the ballreceptacle, means of the character illustrated in plan view in Fig. 5 and in vertical section in Fig. 6 may be employed. Beneath the ball-receptacle 7a and cover plate 0 and above the gear-train is arranged a loose plate 0, capable of rotating freely about the axis of the spindle Z. The edge of this plate is at one point formed with a turned down finger 0 Fast upon the stud of the eccentrically mounted gear wheels 9 h is mounted a radial arm 3) so arranged that its outer extremity traverses the path of rotation of the finger 0 The upper surface of the plate 0 is "formed with slight humps 0 which contact with the underside of the cover plate 0 and cause the plate 0 to rotate therewith. The plate 0 and the gear-wheel g rotate, however, at difierent speeds, with the eifeet that the turneddown finger a sometimes comes into contact with the radial arm 72, whilst in the course of other revolutions the finger 0 passes clear of the arm 32. lVhen the two collide, the rotative movement of the plate 0 suffers a momentary check, which check is conveyed to the ball-receptacle is, but without necessarily arresting the rotative movement of the latter, its momentum causing it to slip in relation to the plate 0.
I claimz- 1. Apparatus for use in playing a game of the roulette type, c'on'iprising ai ball-receptacle formed with a lateral orifice, a slightly inclined floor arranged within the ball-receptacle and formed with a chute at its lower edge, the receptacle and floor mounted for rotation about a common axis, driving gear positioned beneath the receptacle and operatively connected to it and the floor whereby to rotate both the ball-receptacle and the floor, the former at a different speed than the latter, and a surrounding play-tabl e, formed with pockets for the reception of the balls ejected from the rotating ball-receptacle.
2. An apparatus of the class described comprising a drive shaiit, a sleeve mounted thereon, a ball supporting disc having a discharge chute carried by the sleeve, a noncircular pinion carried by the shaft, a gear train operat-ively connecting the pinion to the sleeve whereby to rotate the sleeve at a variable speed, a ball receptacle, and means to frictional'ly mount the 'sameon the sleeve whereby the receptacle is caused to slip with respect to the disc during periods of accoloration and deceleration to discharge the balls therefrom.
3. An apparatus of the class described comprising a drive shaft, a sleeve carried by the shaft, a disc having a discharge chute carried by the sleeve,-a pinion carried by the shaft, a gear train operatively con necting the pinion with the'sleeve and including an eccentrical ly mounted pinion whereby the sleeve is driven intermittently, a receptacle 7 having a lateral opening formed therein, and means to frictionally mount the receptacle on the sleeve and surrounding the disc whereby the receptacle is caused to slip with respect to the disc by the variations in the speed of the latter to discharge balls supported thereon through the opening in said receptacle.
4. An apparatus of the class described comprising a drive shaft, a non-circular pinion carried thereby, a sleeve mounted on the shaft, a disc carried by the sleeve and provided with a discharge chute, a second shaft, a pinion carried thereby and meshing with said non-circular pinion, a pinion charge chute of the disc, and means to fricrespect to the intermittently tionally mount the receptacle on the sleeve whereby the receptacle is caused to slip with disc during periods of celeration and deceleration to cause balls supported by the disc to 'be discharged through the opening in the receptacle.
