8 x 6 1/2" (20.3 x 16.5cm)
Massey's patent "relates to a new and improved liquid-measuring funnel, and consists in indicating the quantity on a wheel, revolved by either a coiled spring or weight, and by a float, which rises with the liquid, and also in a valve on the bottom of the funnel, which is opened and closed from the top of the funnel..." He said the advantage to this improvement is that "for retailing liquids, it will not only save much valuable time, but prevent waste." (Patent Number 90,457)
