Abstract
Abstract Apparatus for charging the cavity in the mold plate of a patty machine with a food product, such as a meat product to form hamburger patties. The charging apparatus includes a cylinder having a first opening for receiving the food product and a second opening, peripherally displaced from the first opening, through which the product is discharged from the cylinder into the mold plate cavity. A piston is rotatably mounted in the cylinder and conveys the food product from the first opening to the second as the piston rotates about the longitudinal axis of the cylinder.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
A patty machine comprising: a. a cylinder having radially spaced charging and discharging openings, b. a piston rotatably received in said cylinder, c. means defining a radially disposed relieved portion in said piston, d. means for rotating said piston about the longitudinal axis of said cylinder between a first position in which said relieved portion communicates with said charging opening and a second position in which said relieved portion communicates with said discharge opening, e. a stationary center block extending from the wall of said cylinder inwardly into said relieved portion of said piston, f. a mold plate having portions defining a mold cavity therein, g. means for reciprocally moving said mold plate between a first position in which said mold cavity communicates with said discharge opening and a second position in which a molded patty can be removed from said mold cavity, and h. means for supplying moldable patty material to said charging means.
Claim 2
Dependent Claim
155 words
A patty machine comprising: a. a cylinder having radially spaced charging and discharging openings, b. a piston rotatably received in said cylinder, c. means defining a radially disposed relieved portion in said piston, d. means for rotating said piston about the longitudinal axis of said cylinder between a first position in which said relieved portion communicates with said charging opening and a second position in which said relieved portion communicates with said discharge opening, e. a stationary center block extending from the wall of said cylinder inwardly into said relieved portion of said piston, f. a mold plate having portions defining a mold cavity therein, g. means for reciprocally moving said mold plate between a first position in which said mold cavity communicates with said discharge opening and a second position in which a molded patty can be removed from said mold cavity, and h. means for supplying moldable patty material to said charging means.
Claim 3
Dependent Claim
37 words
The machine of claim 1 further comprising: a. removable nozzle means mounted in said discharging opening of said cylinder and directing patty material into said mold cavity when said mold plate is in said first position thereof.
Claim 4
Dependent Claim
