H. GESSWEIN April ll, 1950 SWITCH Filed Jan. 15, 1949 INVENTOR Jen J'y Gesswen mami ATTORNEYS Patented Apr. 11, 1950 UNITED STATES PATENT OFFICE SWITCH Henry Gesswein, Stocktcn, Calif. Application January 15, 1949, Serial No. 71,101"
(CL Z00--52) 13 Claims.
This invention relates generally to an eleetric switch.
In certain coin controlled, electrically operated amusement devicessuch as so-cailed "pin-ball machines-a tilt actuatedswitch is interposed in the circuit for the purpose of automatically breaking said circuit and stopping operation of the amusement device when a person manually tilts the device attempting to accomplish improper playing thereof.
It is one object of the present invention to provide a tilt actuated switch which is especially adaptable, but not limited, for use in an amusement device 'as above.
Another object of the invention is to provide a tilt actuated switch, as above, wherein a gravity displaced ball serves as the switch control medium.
A further object of the invention is to provide a tilt actuated switch, as in the preceding paragraph, wherein said gravity displaced ball is dis posed to run on a pair of Spaced but side by side longitudinal supporting fingers one of said fingers being movable laterally upon the ball running in a. predetermined direction along said fingers, and such lateral movement of said one finger controlling the switch A further object of the inventlon is to provide a switch designed for ease and economy of manufacture.
A still further object of the invention is to provide a practical and reliable switch, and one which will be exceedingly efiective for the purpose for which it is designed. l These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following' specification and claims.
In the drawings:
Fig. 1' is a side elevation of the switch, with the housing o'r frame in section; showing the parts of said switch in their normal positions.
Fig. 2 is a cross section on line 2-2 of Fig. 1.
Fig. 3 is a plan view of the switch, with the parts in normal position, as in Fig, 1.
Fig. 4 is a view similar to Fig. 1, but shows the switch with the parts in the positions occupied thereby when said-switch is open under the influence of the gravity displaced ball.
Fig. 5 is a cross section online 5-5 of F'g. 4.
Referring now more particularly to the characters of reference on the drawings, the switch comprises an upstanding housing or frame, indicated generally ati, which frame is of elongated, rectangular configuration, including sides 2 and ends 3. The frame I ,is preferably formed of dielectric material and is adapted to be mounted on a supporting structure by any suitable means (not shown).
Within the frame I', and extending lengthwise thereof, the switch includes a pair of longitudinal supporting fingers 4 and 5 disposed in side by side but spaced apart relation. The supporting fingers 4 and 5 are of fiat strip metal disposed vertically edgewise; the nger 4 being fixed to the frame I by attachment'at opposite ends of said finger to the ends 3 of the frame. The upper edges of the fingers 4 and 5 lie in substantally the same horizontal plane.
The finger 5 is free at one end with respect to the frame l and is mounted at its other end to the corresponding end of the frame by a spring hinge 6 for lateraloutward swinging motion relative to the fixed finger 4. The spring hinge 8 normally but yieldabl maintains the finger 5 substantially parallel to the finger 4. (See Fig. 3.)
A terminal 1 is mounted on the end 3 of the frame l which corresponds to the spring hinge 6; said terminal l being an electrical connection with the laterally outwardly movabe nger 5.
Another terminal 8 is mounted in connection with the side 2 of the frame directly laterally out from the free end portion of the finger 5; said terminal 8 including an inwardly projecting switch point 9 which extends through the adjacent side 2 and terminates adjacent but short of a cooperating switch point I 0 on the near side of said finger 5. When the finger 5 is in its nor-` mal position, as in Fig. 3, theswitch points 9 and I 0 are separated. In other words, the switch is normally open. i
While the present switch is designed for use in a circuit wherein closing of the switch causes the breaking of such circuit, as through a relay, it is obvious that such switch could be designed to open rather than close upon lateral swinging of the fingcr 5 relative to the nger 4.
Such latera swinging of the nger 5 to close the switch is caused by a gravity displaced ball I l. This ball H is preferably of metal, of substantial weight, and of a diameter greater than the spacing of the fingers 4 and 5.
The frame i is mounted within the cabinet of the amusement devi'ce; or other device being con-` trolled, with a very slight tilt toward the spring hinge end of the frame l whereby the ball I l nor mally rests on the fingers 4 and 5 at the end portions thereof adjacent said spring hinge. However, if the amusement device is tiited by a person in an attempt to accomplish lmproper playing of such device, the frame I will be tilted down wardly toward the end opposite the spring hinge 8, as in Fig. 4, Whereupon the ball H is gravitationally displaced from its normal position, as in Fig. 1, to a position at the other end of the frame, as in Fig. 4. When the ball H moves to this latter position its weight causes the finger 5 to Shift laterally outwardly, closing the switch points 9 and !0, and thus closing the switch. As previously described, this results in breaking of the circuit of the ,amusement device, ,and prevents unauthorzed play thereof by manual tilting.
The switch is automatically resetting for the reason that when the device is returned to its' the ball H will have return normal position, travel on the ngers 4 and 5 to its initial or ing position.
While the switch is simplen-its structure, and designed for ready and inexpensive manufacture, nevertheless it provides a very practical and restartliable control for the circuit of any device which may besubject 'to 'ti-lting and wherein 'it is desired to breakthe circuit when "such 'tilt oc'curs.
