IIIIII VIII,
I ureutor Richard J. Mays By 2mm WWW 3M8 4| used for preventing the gasoline when placed in the tank 38 from slushing about, thereby providing a proper and constant feed of fuel to the engine cylinder. A pipe or tube 42 will be connected at be connected at its lower end to the port 44 at the lower end of the cylinder I, whereby the air in the lower part of the cylinder entering through a conventional valved inlet in the wall thereof is compressed as the piston moves downwardly,
:after which the air is forced through'th'e pipe ortube 42 and. into the'up'per end of the cylinder 1 above'the piston 30 to "be further compressed and mixed with the fuel and ignited when the switch arm 26 and the switch or contact finger 21 make contact to close the circuit to the battery l6, coil I5 and spark plug 12. As the piston 3i! movesdownwardly in the cylinder I, the exhaust gases will be discharged or exhausted through the exhaust port 45 and out from the exhaust pipe 46 connected thereto.
A control switch 41 will be disposed upon the handle 3 and will be connected by means of the electric conductorsor wires 48 and 49 to the ignition. apparatus of the gasoline engine.
From the foregoing description, it will be apparent that there'has been devised and provided a highly efilcient form of gasoline engine operated jumping stick which will be highly efiicient an'd'amusing in operation, and relatively inexpensive to manufacture and produce, said: stick being capable of being operatedat various speeds controlled at the will of the operator.
While the preferred embodiment of the instant I invention has been illustrated and described, it
. will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from the spirit of the invention. W
Having thus described my invention what I claim as new and desire to secure by Letters Pa ent of the United States is: I
1. A mechanical jumping stick comprising an upper portion and a lower portion, a hand bar and a foot bar on the opposite ends of said upper portion, a resilient cushioning shoe on the lower end of said lower portion, a gasoline engine disposed between said upper and lower portions and including a cylinder secured to said upper portion, a piston attached to said lower portion and operatively received in said cylinder, guide ports through its wall, and ignition means for igniting the fuel in said cylinder when the same has been compressed therein.
cent the outer end thereof.
means for preventing rotary movement between 2. The subject matter as claimed in claim 1, a fuel deflector on said piston, resilient cushioning means on the head of said piston, and a circuit making and breaking mechanism for automatically closing an electric circuit for igniting the fuel in said cylinder when the same has been compressed.
3. The subject matter as claimed in claim 1, a fuel deflector on said piston, resilient cushioning means on the head ofsaid piston. a circuit making and breaking mechanism for automatically closing an electric circuit for igniting the fuel in said cylinder when the same has been compressed, and a control switch on said hand bar for rendering the engine of said pogo stick either operative or inoperative.
4'. Amechanical jumping stick comprising a cylinder defining a body section, a rigid upper structure extending upwardly from said cylinder, and including vertically spaced hand and foot bars, a reciprocating lower structure operatively extending from the lower end of the cylinder and including a piston rod having a resilient cushioning element disposed on its outer end, a piston slidably mounted in said cylinder and connected to the inner end of the piston rod, guide means for preventing rotary movement between said cylinder and piston, a fuel tank disposed circumferentially of said cylinder, said cylinder having fuel inlet and exhaust ports through its wall, and. ignition means for igniting the fuel in said cylinder and control means responsive to the sequential reciprocation of the piston rod in the cylinder for said ignition means.
5. The combination ofclaim 4, wherein said guide means includes an elongated key formed in said piston rod and a complementary groove formed in the lower end of the cylinder.
6. The combination of claim 4, wherein resilient means is disposed in the cylinder betweenthe upper end thereof and the piston for cushioning the action of the piston and urging the same downwardly in the cylinder.
'7. The combination of claim 4, wherein said control means for the ignition means includes a source of electrical energy carried by the cylinder, a switch interposed between said source and the ignition means.
8. The combination of claim 7, wherein said switch includes a fixed positive contact carried by the lower end of the cylinder and a movable ground contact secured to the piston rod adja- RICHARD J. MAYs.
