 Levi Snow of New Haven and Alon- 20 H. Warner Of New Britain have pa tented food chopper. It is described as having a cylindrical primary fore ing chamber and confcal secondary forcing chamber which is larger than the first chamber. A cylindrical forceT corresponding in diameter to the prl- mary chamber, but smaller than the secondary chamber. Cutting arms are arranged to spring from the forward partition of the inclined wall of the secondary chamber so as to leave the rear portion Of the chamber unob- structed for the reception Of the deliv- cry end of the forcer. A cutter is pro vided, carried by the forcer which CO., acts with the outer faces of the arms to cut the food. The food expands in the secondary chamber in which the ribs of the forcer co-act through the food with the inclined wall to produce direct forward pressure. supplementing the pressure developed in the primary forcing chamber, whereby the food is forced between the arms upon the outer faces of which it is cut by the cutter. MT Warner has assigned his interest in the invention to his CO., inventor, MT Snow.

A dia- phragm is located upon the upper face of the sleeve to which the collar is clamped, the diaphragm being perfer- ated to permit the thermometer to be passed into the tube.
