Abstract

Automatic bowling game, perfected, which is characterized, because in the upper part of the track precisely where the pins are implanted to proceed with the throwing, there is a frame, which covers said space substantially above those, and in which it has an electric motor, with a speed reducer that transmits its rotation to an axis, which has two cranks at its two ends, linked to two rockers by means of two connecting rods, and whose rockers are joined together by a knee parallel to that axis, and below whose roller pass the strings attached at one end to the heads of their respective pins take their other end to overload detection levers, tensioned by two springs mounted on the chassis of the machine, passing said strings through of conduits that are part of the device for detecting the falls of the boluses, and whose conduits through which the strings run, are provided with grooves or flutes. Jeros through which access to the inside of the tubes paths rollers, which are displaced by a knot made previously in each rope, when the bolus is knocked down, driving these wheels to their respective micro-switches that lock to their relevant roles.
