Application June 17, 1949, Serial No. 99,723
The present invention relates to bubble shooters and it consists in the combinations, constructions and arrangements of parts herein described and claimed.
Generally, there is provided a bubble shooter or bubble blowing device which consists essentially of an air pump having an outlet valve at one end and at which end is attached a reservoir for containing so-called bubble soap and at which end is pivotally mounted a film producing element which is in the form of a bell crank lever having a ring at the end of one arm which is adapted to be dipped into the container and a spring connected with the other arm of said bell crank lever. A piston is provided for the pump and a handle is provided for the piston rod. To the handle is aflixed or formed integrally a second rod which is parallel to the piston rod and which is mounted within a housing afiixed to the outer side of the pump. The spring is attached to the second rod and is adapted to normally hold the ring of the film forming device in registry with the outlet opening of the pump. When the piston is forced inwardly of its cylinder to a point adjacent its innermost point of travel, it will cause the spring to completely collapse and further movement inwardly of the piston and the secondary rod will cause the spring to move downwardly into the soap mixture. Thereafter outward movement of the piston will again bring the ring into registry with the outlet opening of the pump. Thus bubbles may be formed by a continuous pumping motion, such pumping motion causing an automatic dipping and replacement of the filament forming means.
It is accordingly an object of the invention to provide a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and eificient in use.
Another object of the invention is the provision of automatic means for replenishing with bubble soap a film forming mechanism forming a part of the invention.
A further object of the invention is the provision of novel means for bringing a film forming mechanism into and out of registry with the outlet opening of a pump forming a part of the invention.
(Ether and further objects of the invention will become apparent from a reading of the Figure 2 is a plan view thereof,
Figure 3 is a front elevational view of the device shown in Figures 1 and 2,
Figure 4 is a sectional view taken along line l 6 of Figure 2,
Figure 5 is a vertical sectional view thereof,
Figure 6 is a view similar to Figure 5 but showing a piston and its associated parts, forming a part of the invention, in their outermost position, and 1 Figure 7 is a fragmentary perspective view of the device.
Referring more particularly to the drawings, there is shown therein a pump cylinder it) having a plug II in its rearward end and which plug H is held in position by a crimp 12 in the rearward end of the cylinder Ii]. The forward end of the cylinder I9 is provided with a cap [3 which is afiixed thereto by welding and the like and which is simply provided with a restricted air outlet fitting I4. I
A piston I5 is slidably mounted within the cylinder H3 and is provided with a piston rod hi which extends rearwardly through the plug H, as indicated at Ila, and which terminates in an integrally formed handle IT.
A spring housing [8 is amxed atop the cylinder It and extends longitudinally thereof. A spring actuated rod 19 is formed integrally with the handle I! and extends into the housing IS. A container 20 is provided with an upwardly extending rear wall 2| through which the fitting l4 extends and a bracket member 22 is also mounted upon the valve I4 and is held in position thereon by means of a nut 23 which is threaded on the outer side of the fitting M.
The container 20 is provided with an opening 24 in its upper side and a bell crank lever 25 is pivotally mounted in the upper end of the bracket 22.
A relatively long arm 25 of the bell crank lever is provided at its outer end with a circular film forming device 2'! and its relatively short arm 28 has afiixed thereto one end of a spring 29, the other end of which extends into the housing l8 and is attached to the rod It, as indicated at 30. The container 20 is adapted to contain a bubble forming mixture 3|.
In operation, it will be apparent that when the handle H is moved rearwardly of the cylinder in air will be drawn into the cylinder ll) through the fitting it and at the same time the spring 29 will be tensioned by the rearward movement of the rod 19 the result being that the bell crank lever will be moved to a position as viewed in 3 either Figure 5 or Figure 6 thus bringing the ring 21 into registry with the fitting 14, as indicated in Figure 6. Upon the forward movement of the rod 16 the rod l9 will likewise be moved forwardly and the piston 15 will be moved forwardly to force air in a stream through the fitting M to impinge upon a film of soap and water which at this time covers the space within the ring 21 due to its immersion in the mixture 3|. to be formed and blown away from the entire device until the piston [55 arrives at a point adjacent the forward end of the cylinder [0, at which time the spring 29 will have reached its uttermost contraction after which, upon further forward movement of the rod I6 and the rod 19 the spring 29, being new compressed, will force the arm 28 forwardly and downwardly and hence force the arm 26 in a like direction, as indicated in Figure 5, to again immerse the ring 21 in the fluid 31. Rearward motion of the handle 11 will again begin the cycle just above described so that constant movement of the pistonv in a reciprocatory manner will cause a continuous stream of bubbles to be formed by the device.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.
What is claimed is:
1. A device of the character described comprising a cylinder having an air outlet fitting inits forward end, a plug affixed to the rear end of said cylinder, a piston within the cylinder, a piston rod extending through the plug and connected with said piston, a handle at the outer end of the piston rod, a liquid container dependently aflixed to the forward end of the cylinder, an arm pivotally connected to the forward end of the cylinder, a ring formed at the outer end of said arm, and a tension spring interconnecting said arm and said handle for normally holding said ring in registry with the fitting when the arm is drawn outwardly, said spring having its tension releasable.
This stream of air will cause bubbles 2. A device of the character described comprising a cylinder having an air outlet fitting in its forward end, a plug aifixed in the rear end of said cylinder, a piston within the cylinder, a piston rod extending through the plug and connected with said piston, a handle at the outer end of said piston rod, a liquid container dependently aifixed to the forward end of said cylinder, an arm pivotally connected to the forward end of the cylinder, a ring formed in the outer end of said arm, said arm being swingable to move said ring into said container in a downward direction and into longitudinal registry with said air outlet fitting in an upward direction, an open-ended housing longitudinally afiixed to the top of the cylinder, a secondary rod extending from said handle into said housing, and a tension spring interconnecting the arm and the free end of the secondary rod, said spring having its tension releasable with the consequent downward movement of the arm causing the ring to move downwardly into said container and said spring forming a yieldable link between the arm and the secondary rod when the piston is moved outwardly whereby to move the ring into the aforesaid longitudinal registry with the air outlet fitting, said piston rod, secondary rod and said handle being all formed of a single piece of material.
