C. M.'ROTH FAUCET ATTACHMENT FOR BUBBLE BATH Jan. 11, 1955 Filed Aug. 4, i950 United States Patent Ofitice 2,699,357 FAUCET ATTACHMENT FOR BUBBLE BATH Charles M. Roth, Berwyn, Ill. Application August 4, 1950, Serial N 0. 177,729 1 Claim. (Cl. 299-107) This invention relates to an attachment for faucets and it relates more particularly to an attachment by which a large volume of bubbles are generated in a bath tub.
The usual bath tub faucet is adapted to direct a stream of water almost perpendicularly downward into the body of water already in the tub. Under such circumstances, it has been found that the formation of bubbles, after the water is properly softened, occurs only in the area where the oncoming stream strikes the surface of the water and the bubbles which are formed remain substan tially in the same area and are not distributed throughout the tub. The amount of bubbles formed by this arrangement is at a minimum because the oncoming stream of water is unable to engage the surface of the water in the tub in a manner to create greatest turbulence, the force of the oncoming stream is slowed by previous engagement with the volume of bubbles already there, and the impact of the stream with the formed bubbles causes their breakdown so as to eliminate some portion of the already formed bubbles.
An object of this invention is to produce an attachment of the type described by which the stream of water is directed on to the surface of the water already in the tub at an angle to create maximum turbulence while entrapping air in greater volume for bubble formation. The impact of the stream with the body of water at an angle causes a desirable body of water for bubble formation.
More particularly, provide an attachment of the type descr bed which may and simple in operation.
These and other objects of this invention will hereinafter appear, and for purposes of illustration, but not of limitation, an embodiment of the invention is shown in the accompanying drawing, in which Figure 1 is an elevational view of an attachment embodying features of this invention;
Figure 2 is an end view from the top of the attachment shown in Figure 1;
Figure 3 is an enlarged sectional elevational view taken along the line 3-3 of Figure 1, and
Figure 4 is a plan view showing the attachment in position of use on the end of a faucet, and indicating the reaction thereof when in use in a bath tub.
he principles of this invention reside in a faucet attachment having a restricted outlet portion disposed at an acute angle with the surface of the water in the tub or the like, for the purpose of directing the stream of Water at high velocity into the body of water at an angle to create maximum gent or other surface-active chemicals, the bubbles that are formed remain and pile up in larger volumes than have heretofore been possible by ordinary use of a faucet.
at an angle between 20 and 45 degrees, with the vertical, and preferably about 35 degrees. An angle greater than degrees is undesirable because thrown out too far so that the force is mostly spent before it strikes the surface of the Patented Jan. 11, 1955 tub. Although it is not essential, best results are secured when the nozzle portion is formed to have an outlet of lesser dimension than the tube 10 in order to force the stream of water from the nozzle at greater velocity. It has also been found best to flatten the end portion of the tube, as at 11a, so that the nozzle is in the form of an elongate opening which causes the water to issue in a ribbon-like stream further to increase the area of engagement with the body of water 14.
The tube portion 10 is shown as being joined to the faucet 15 by an adapter 16 formed of rubber or rubberlike materials having ribs 17 about the outer wall to provide a better gripping relation for manually forcing the adapter onto the faucet or for removing same from position of use. To establish a desired gripping relation which militates against the adapter being forced off of the faucet and in order to provide for the use of the adapter with all sizes of conventional faucets, the bore through the adapter is decreased in stepwise arrangement, as illustrated by figures 18, 19 and 2 0. Circumferential grooves 21, having a sharp abutment 22 in the direction to resist removal of the adapter from the faucet, are circumferentially arranged throughout the bore to enhance the permanence of the assembled relation.
The tube 10 is secured in position of use by a frictional grip established between the end portion 23 of the tube and the outer end portion of the bore 24 which is adapted to be stretched when the tube is inserted therein. Instead, other means may be used, such as forming the end of the tube with a flared portion adapted to rest formed where the bore is reduced through which the tube is inserted when in position of In a further alternative, the adapter and the tube may comprise a unitary assembly which may be screwed or otherwise secured onto the faucet.
It will be apparent from the description that an attachment of the type described may be readily placed upon the end of a faucet so as to direct the stream of water at high velocity and at a desirable angle into the body of water in the tub, whereby maximum turbulence and hubble formation is achieved. The angular relation is adapted also to cause constant circulation of the water in the tub so that the bubbles that are formed may be distributed over the entire area. In the event that the faucet member is otherwise originally disposed, the attachment should be modified so that the nozzle causes the oncoming stream to issue at the described angle for most effective reaction with the water.
It will be understood that numerous changes may be made in the details of construction, arrangement and operation without departing from the spirit of the invention, especially as defined in the following claim.
