Another interesting use for the Sparklets bulb was

offered in a 1935 invention by Bert E. Wallace of

Barrington, Illinois. His U. S. Patent No. 2,014,824

detailed a dispensing apparatus "for dispensing beer

and similar beverages" which would take up minimal

space in a refrigerator.

While Campbell was working on bulb improvements

at Sparklets, others were working on novel designs for

soda syphons. In 1936 Lawrence Ward, a New York

City inventor, applied for a patent for a "Dispensing

Apparatus." Like Campbell he referred to the capsule

using "…a high pressure carbon dioxide container

known to the trade as a 'Sparklet bulb'." Ward's

discussion in the application is primarily concerned

with the method in which the bulb is pierced to

release the gas and syphon off the liquid.

On August 1, 1936, within four months of the

"Dispensing Apparatus" application, Ward filed for a U. S. Design patent for a Syphon

that was destined to become a well-recognized form. The

assignee for his Design Patent 101,421 issued September

29, 1936 was Sparklets Limited, London.

The design patent was followed up with a mechanical

patent application on August 20, 1936 (Patent No.

2,092,596) issued September 7, 1937 in which he states

"These siphons as heretofore made usually consist of a

glass bottle or vase that is reinforced by a woven wire

jacket or other metallic covering as in the well-known

'Sparklets' name." Included among several objectives,

Ward says, "Still another object of the invention is to

provide an all metal siphon, thereby doing away with the

glass vase." He also designed it with interchangeable

siphon and cocktail shaker heads.
