Abstract
Abstract A duct having an inlet end and an outlet end and attached thereto in register with the outlet end is a loop adapted to hold the bubble making solution in a thin film, whereby air expelled through the duct will be propelled through the loop and cause the formation of bubbles from the bubble making solution. A support arm connects the duct and loop to hold the two in relative operating position. The support arm is connected to the loop by a flexible bridge or hinge which allows the arm to pivot from a plane parallel with the loop to a position perpendicular to the plane of the loop. A pop bead type of connection on the arm and loop serve to lock the arm in position perpendicular to the plane of the loop.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
157 words
In the combination to form a bubble making apparatus, means forming a duct adapted to convey air from an inlet end to an outlet end and means forming a loop for holding a film of bubble making solution, means for attaching said loop means and said duct means together for holding them in operative position, in operative position said loop means being located whereby air expelled from the outlet end of said duct means passes through the aperture bounded by said loop means, the improvement comprising: a relatively rigid support arm flexibly attached to said loop means, the flexible attachment between the arm and loop allowing said support arm to pivot from a position approximately perpendicular to the plane defined by said loop means to a position approximately parallel with said plane, and means for locking the support arm and loop means in position with the arm approximately perpendicular to the plane defined by said loop means.
Claim 2
Dependent Claim
157 words
In the combination to form a bubble making apparatus, means forming a duct adapted to convey air from an inlet end to an outlet end and means forming a loop for holding a film of bubble making solution, means for attaching said loop means and said duct means together for holding them in operative position, in operative position said loop means being located whereby air expelled from the outlet end of said duct means passes through the aperture bounded by said loop means, the improvement comprising: a relatively rigid support arm flexibly attached to said loop means, the flexible attachment between the arm and loop allowing said support arm to pivot from a position approximately perpendicular to the plane defined by said loop means to a position approximately parallel with said plane, and means for locking the support arm and loop means in position with the arm approximately perpendicular to the plane defined by said loop means.
Claim 3
Dependent Claim
65 words
The combination of claim 1 wherein the locking means comprises a nipple on one of the arm and loop means and a concavity on the other, the concavity being at least partially smaller than the largest part of the nipple and formed of resilient material, whereby the nipple is gripped and held by the deformed surface of the concavity when the nipple is inserted therein.
Claim 4
Dependent Claim
31 words
The combination of claim 2 wherein the end of the support arm remote from the loop means is shaped to be joined with a cooperatively shaped structure of said duct means.
Claim 5
Dependent Claim
27 words
The combination of claim 3 wherein the duct means includes two outlet passages at its outlet end and a loop means in register over each outlet passage.
Claim 6
Dependent Claim
27 words
The combination of claim 2 wherein the duct means includes two outlet passages at its outlet end and a loop means in register over each outlet passage.
Claim 7
Dependent Claim
27 words
The combination of claim 1 wherein the duct means includes two outlet passages at its outlet end and a loop means in register over each outlet passage.
Claim 8
Dependent Claim
31 words
The combination of claim 6 wherein the end of the support arm remote from the loop means is shaped to be joined with a cooperatively shaped structure of said duct means.
Claim 9
Dependent Claim
31 words
The combination of claim 1 wherein the end of the support arm remote from the loop means is shaped to be joined with a cooperatively shaped structure of said duct means.
Claim 10
Dependent Claim
67 words
The combination of claim 3 wherein the means for attaching the loop means and the duct means comprises a resilient open loop on the end of the arm remote from the Loop means, said resilient open loop having a side opening smaller than the duct means whereby, the duct may be forced through said side opening and gripped by the inside surface of the resilient open loop.
Claim 11
Dependent Claim
54 words
The combination of claim 3 wherein the means for attaching the loop means and the duct means comprises a slot in one of the duct means and arm means and a cooperatively shaped probe on the other whereby the probe inserted into the slot serves to lock the loop means and duct means together.
Claim 12
Dependent Claim
63 words
The combination of claim 1 wherein the duct means incorporates therein a rotor with an axle and radially extending vanes, a decorative element being mounted on said axle and being visible from the exterior of said duct, means for directing a stream of fluid passing through said duct to impinge tangentially on said vanes to thereby rotate said rotor and said decorative device.
Claim 13
Dependent Claim
34 words
The combination of claim 1 wherein the interior surface of the loop means includes means forming surface irregularities for storing larger amounts of bubble solution than are stored with a correspondingly smooth interior surface.
Claim 14
Dependent Claim
45 words
The combination of claim 1 wherein the locking means comprises an elongated aperture in one of the loop means and the support arm and an elongated nipple on the other, the nipple having a portion larger in cross-section than the smallest cross-section of the aperture.
