Abstract: 290,268. Bernhardt, F. G., and Bernhardt, G. W., (trading as Bernhardt, F.) [Firm of]). May 12, 1927, [Convention date]. Gill boxes.-In a gill box having two sets of intersecting fallers the upper set a of which can be lifted vertically from the lower set b, the upper set is driven from the lower set by gearing which is slidable along and rotatable with vertical shafts driven from the lower set. The frame of the upper set slides on rods c and is lifted by an arrangement of a hand-wheel and bevel or other suitable gearing. ton in the preparation of material for felt, batting for upholstery, &c., comprises a casing 14 mounted on a stand 10. In the upper part of the casing is a hopper 17, in which the cotton is placed, formed by a partition 15 and a baffle plate 16. Toothed rollers 18, 19 occupy the space between the partition and plate, and are driven in the same direction.

IPC: E03C1/20
Filed: 1922-03-22
Abstract: 193,716. Delattre, J. H. March 22, 1922. Closure members, rotary conical.-An ejector device for filling and emptying receptacles such as baths is formed as a three-way rotary plug cock f provided with an injector nozzle j operable by a handle and connected to the water supply, the discharge pipe c, and the receptacle. In the discharge position of the valve the pressure water supplied through the connection b flows through an ejector nozzle j and discharge the waste water communicating with the passage in front of the nozzle. The pipe c is in the form of a Venturi double cone at the part adjacent to the casing of the valve. The nozzle is formed of two narrowing cones i<1>, i and a short cylindrical piece h. In the mid-position the valve closes the discharge and supply pipes, while in the other extreme position water is permitted to flow freely into the baths, the discharge pipe c then being cut off. For the purpose of discharging water to a higher level, air may be admitted to the water in the discharge pipe to lessen the weight of the column of liquid being discharged, by forming this pipe of a suitable position with an adjustable air inlet.
