Claim 12

The structure according to claim 10 wherein: a variable sized air chamber is formed within the first tube and second tube for alternately compressing and drawing in air as the first and second tubes are slid longitudinally relative to one another.

Claim 13

The structure according to claim 11 including: a diaphragm positioned within the first tube and formed with an air pressure aperture; and, a linking tube extending between the air passage aperture and cylinder first port in order to place the cylinder and air chamber in mutual fluid communication.

Claim 14

The structure according to claim 11, including: an air barrier secured to the cylinder and positioned to generally block the flow of air around the cylinder.

Claim 15

The structure according to claim 13 wherein: the air barrier has a pair of wing walls extending laterally from opposite sides of the cylinder into contact with the casing front section.

Claim 16

The structure according to claim 10 including: stop means for preventing the first tube from sliding off the second tube; and, guide means to prevent relative rotation and twisting between the first tube and second tube.

Claim 17

The structure according to claim 15 wherein: the guide means includes a longitudinally extending guide slot formed in one of said tubes; and, the stop means includes a key fixed to the other of said tubes and projecting into the guide slot, the key being arranged to slide within the guide slot and make contact after a predetermined length of travel.

Claim 18

A bubble gun toy comprising: a. a casing simulating a gun and having an elongated hollow front section and a rear section; b. a cylinder positioned within and extending laterally across the casing front section; c. a guide slot formed in a front side wall portion of the cylinder and extending longitudinally from the top end of the cylinder; d. a first port formed through the lower end of the cylinder; e. a second port formed through an intermediate portion of the cylinder, the guide slot being longitudinally aligned with and terminating near the second port; f. pumping means coupled to the casing for alternately driving a charge of compressed air sequentially through the first and second ports to assist in forming bubbles, and, drawing a fresh charge of air sequentially back through the second and first ports; g. a shuttle in the cylinder arranged for travel between the first and second ports, the shuttle being lifted beyond the second port when a charge of compressed air is driven through the cylinder and pulled forcibly to a level adjacent the first port when a fresh charge of air is drawn through the cylinder; h. an arm connected to the shuttle and projecting through the guide slot; i. a torus-shaped reservoir for holding bubble producing liquid coupled to the casing front section and having an arcuate slot formed in an inner wall portion, the reservoir having a central opening concentrically aligned with the second port; and, j. a dip ring carried by the arm and oriented to pass through the reservoir arcuate slot and into the reservoir as the shuttle is forcibly pulled, and, be lifted from the reservoir as the shuttle is lifted.

Claim 19

A bubble gun toy comprising: a. a casing simulating a gun and having an elongated hollow front section and a rear section; b. a cylinder positioned within and extending laterally across the casing front section; c. a guide slot formed in a front side wall portion of the cylinder and extending longitudinally from the top end of the cylinder; d. a first port formed through the lower end of the cylinder; e. a second port formed through an intermediate portion of the cylinder, the guide slot being longitudinally aligned with and terminating near the second port; f. pumping means coupled to the casing for alternately driving a charge of compressed air sequentially through the first and second ports to assist in forming bubbles, and, drawing a fresh charge of air sequentially back through the second and first ports; g. a shuttle in the cylinder arranged for travel between the first and second ports, the shuttle being lifted beyond the second port when a charge of compressed air is driven through the cylinder and pulled forcibly to a level adjacent the first port when a fresh charge of air is drawn through the cylinder; h. an arm connected to the shuttle and projecting through the guide slot; i. a torus-shaped reservoir for holding bubble producing liquid coupled to the casing front section and having an arcuate slot formed in an inner wall portion, the reservoir having a central opening concentrically aligned with the second port; and, j. a dip ring carried by the arm and oriented to pass through the reservoir arcuate slot and into the reservoir as the shuttle is forcibly pulled, and, be lifted from the reservoir as the shuttle is lifted.
