1 Claim. (Cl. 46-7) The present invention relates to improvements in toy bubble pipes for making bubbles from a soap solution.
The present invention has for its primary object to provide a soap bubble pipe which will permit the making of bubbles as large as three feet in diameter, a feat that is astounding and surprising to children and adults alike and which has not heretofore been possible with the bubble making pipes presently on the market.
The present invention attains this object by providing the pipe with a plurality of arms which are spherically shaped on an arc of up to three feet in diameter, and which are formed with small reservoirs to slowly dispense more solution to the bubble as it grows, it being known that the bubble size is dependent upon the amount of solution available at the pipe mouth.
Another object of the invention is to provide a bubble pipe with a reservoir which will contain sufficient solution for a series of smaller bubbles which are formed one at a time and shaken off as desired.
A further object of the invention is to provide a bubble pipe which has a spherical surface to which the bubble will cling after it is formed, and which therefore satisfactorily holds a bubble for display a relatively long period because its film is replenished for a short period by more solution supplied from the reservoirs.
These and other objects and advantages of the present invention will be readily apparent from consideration of the following description when taken with the annexed drawings in which like numerals indicate like parts throughout the several views and in which:
Figure 1 is a view in perspective of an embodiment of the present invention showing a bubble blown thereon;
Figure 2 is a top view in section taken on line 2-2 of Figure 1;
Figure 3 is a bottom view of the present invention; and
Figure 4 is a cross sectional view taken on line 4-4 of Figure 2.
Referring in greater detail to the drawing, the illustrated embodiment of the invention will be seen to consist of a hollow bowl or housing 10, formed of plastic or other material that may be molded, and having a pipe stem 11 projecting from the housing near its closed end 12. The other end of the housing is formed with a convexly curved face 13 which is provided with an opening 14. A spout 15 extends inwardly and upwardly into the housing and forms between it and the side wall 16 of the housing a reservoir 17 which will hold a small quantity 2,739,413 Patented Mar. 27, 1956 of soap solution when the pipe is dipped into a supply, as in the conventional way of blowing soap bubbles.
The housing 10 has attached to it around the end opposite the closed end a plurality of arms 18, here shown as five in number although more or less may be used as desired. Arms 18 are curved as though part of a sphere of about three feet in diameter, and have their lower faces 19 concavely shaped and meeting with the annular face 13 on the housing in such a manner as to form a smooth spherically shaped surface. On the upper faces 21 of the arms 18 are formed a series of depressions 22 and each has a hole 23 through to the inner or lower face 19. The housing 10 has other holes 24 through its face 13 and extending into the reservoir formed between the spout 15 and the housing side wall 16, these latter holes 24 being somewhat smaller in diameter than the holes 23 in the arms for the reason that the pressure of the air as itis blown into the housing and out the opening 14 tends to equalize the rate of drip of the solution to the bubble being formed.
The arms 18 are here shown to be tapering from the housing outwardly to their ends, but may be of other shape if desired. The bubble pipe will hold a bubble for a relatively long period on its spherically shaped lower surface, with the arms more effective than a true spherical or circular shape, the portions of the bubble between the arms, as it is formed, depending slightly downward and permitting the even distribution of the solution from the reservoirs. As is easily understood, a relatively large number of smaller bubbles may be blown, and shaken off, without refilling the reservoirs of the housing and the arms.
Though only a single embodiment of the invention has been here shown and described, other embodiments, as well as many changes and modifications are contemplated and may be made within the spirit and scope of the invention as set forth in the appended claim.
What is claimed is:
In a soap bubble pipe, a hollow bowl having a closed end and another end and a side wall, a pipe stem projecting from said side wall and communicating with the interior of the bowl at a point remote from said other end of the bowl, means partially closing said other end of the bowl and providing an opening smaller in diameter than said other end, a plurality of arms projecting from said other end of the housing, said arms being circumferentially spaced around the housing and having surfaces remote from the housing, said remote surfaces being uniformly concave and conforming in curvature to a segment of a sphere, said arms having holes extending therethrough, and spaced along the arms, and soap solution recesses in the opposite sides of the arms communicating with said holes.
