APPLICATION FILED MAY I, 1915- Patented Mar. 14, 1916.




I Application filed May 1, 1915. Serial No. 25,222.

To all whom it may concern:

Be it known that I, IoNA'rrUs Lucas, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented a new and useful Froth-Producing Implement, of which the following is a specification.

My invention relates to improvements in a froth producing implement in which a reciprocating compound piston fitting into a container sucks air through a hollow pistonrod into the container by one motion and pushing by the other motion this air with the liquid previously put into the container though specially placed apertures of the compound piston-head, which consists of a lower part fastened to the hollow pistonrod and an upper part movable upon the piston-rod upward and downward acting as a valve with the aforesaid lower part of the piston-head; thereby forcibly mixing the air with the liquid and producing froth.

In operating this froth producing implement, the air before it enters the hollow piston-rod, is filtered by forcing this air through an aseptic, absorbent substance placed in a receptacle on top of the hollow piston-rod making the said operation sanitary and the objects of my improvement are, first, to quicken the operation of froth making, second, to provide a sanitary way of producing froth should the same be used for food.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figures 1, 2, 3, are vertical sections of the entire implement; Fig. 4, is a top-view of the implement, Fig. 5, is a top view of the upper part of the compound piston-head, Fig. 6, is a top view of the upper and lower member of the compound piston head.

Similar letters refer to similar parts throughout the several views.

The container A, Figs. 1, 2, 3, 4, forms the casing inside of which the compound piston B, reciprocates. To avoid corners which might not be readily cleansed and so become a place for filth to accumulate, I make the bottom of the container A, round. The top of the container A, (which for the aforesaid reason can also be made round) is removable and has a sleeve C, Figs. 1, 2, 3, 4, through which the hollow piston-rod I, Works. The compound piston B, Figs. 1, 2,

3, 4, which is made to slide up and down in side of the container A, is composed of a compounded head D, Figs. 1, 2, 3, 4, 6, and

the hollow piston-rod 1, Figs. 1, 2, 3, 4. The receptacle E, Figs. 1, 2, 3, is outside of the container A, and is placed on top of the hollow piston rod 1. The piston head D,

Figs. 1, 2, 3, 4, is composed of a lower member 2, Figs. 3, 4, 6, securely fastened to the lower part of the hollow piston-rod I, shown at 3, Figs. 1, 2, 3. The upper member 4, Figs. 1, 2, 3, 5, slides upward and downward upon the hollow piston-rod but is prevented from turning sidewise on the said pistonrod by a key 5, Fig. 6. Both members 2, and 4, Figs. 1, 2, 3, of the piston-head D, conform with the shape of the bottom of the container A, Figs. 1, 2, Both members, 2, 4, of the compound piston-head have apertures 6, 7, and the apertures 6, of the lower member 2, Figs. 1, 2, 3, 4, '5, 6, are placed different relative to the apertures 7, of the upper member 4, Figs. 1, 2, 3, 4, 5, 6, in fact the upper member 4, closes the apertures 6, of the lower member 2, when the compound piston-head D, is at the bottom of the container A, also when the compound piston is moved upward Figs. 1,2. On the downward stroke of the compound piston B, the upper member 4, is lifted away from the lower member 2, by the exsutfiating fluid Figs. 2, 3, 4.

Inmanipulating my aforedescribed froth producing implement any tenacious liquid such as the white of the egg, cream or the like, that has now been placed into the said container will be turned into froth as the piston of the said implement in moving upward sucks air through the receptacle down the hollow piston-shaft and underneath the compound piston and by the downward motion of said compound piston pressing sucked-in air on and into the liquid mixing and forcing the air and liquid through the numerous apertures producing thereby in the liquid a multitude of air bubbles which in reality are froth.

Having thus described my invention, I
