Our invention is illustrated in the accompany- Before describing the operation of the device, ing drawing forming a part of this application, it is best to refer to Figure 3 where the bottom in which plan View of the rotating die A is shown. The Figure 1 is a front elevation of the device; bottom of the die has spiral grooves 2| therein 25 Figure 2 is a side elevation, partly in section; of a cross sectional shape as shown Pin Figure 4.

The casthey move the hamburger toward the flange I5 ing supports a motor 3 and the motor in turn and this is due to the gently curving rear edges carries a gear reduction housing 4. A shaft 5 of the grooves. Moreover, the gently curving projects through the housing and is slidably rear edges will permit air to enter between the keyed to a worm gear E. The worm gear meshes bottom of the die and the hamburger with the 40 with a worm 'I that is mounted on a motor result that any suction between the hamburger shaft 8. and the die bottom will be broken and the die will A two piece hamburger patty-forming die is lift clear of the hamburger when the lever I9 is removably secured to the lower end of the shaft freed. 5.

The die B is held is slidablymounted on the shank 9 and shaft I0. against rotation by the lug I5a and pin I5. The When the shaft 5 is in raised position, the disc lever is manually moved downwardly until the I2 will bear against a washer I4 and will lift the housing die B covers the hamburger. Further downward movement of the lever will bring the rotating die A down upon the meat and the spiral grooves 2I will spread the meat toward the ange. The handle I9 is continued in its downward movement until a certain back pressure is developed which will indicate to the operator that the meat has been spread to a uniform thickness within the die housing B. The shaft 5 rotates in a cap 5a that in turn is pivotally connected to the lever I9 at 49a. The spring I8 is fully expanded when the disc I2 and housing I3 are raised above the base I as 'shown in Figures 1 and 2.
The handle or lever I9 is` now freed and the perfectly formed patty will remain on the paper while the spring I8 raises the double die. The patty will have a periphery of a perfect circle and the thickness of the patty will be uniform throughout. Another quantity of meat may be brought into registration with the double die and the operation repeated. The device materially speeds up the proper forming of hamburger patties and gives a uniform product at all times.
.It is especially adapted for restaurant use or at hamburger stands where a large quantity of hamburger patties must be made in a short time.
While We have shown only the preferred form of our invention, it should be understood that various changes or modifications may be made within the scope of the appended claims without departing from the spirit of the invention.
We claim: 1. In combination, a base for supporting a quantity of hamburger, a rotating shaft, a disc .5 carried by the shaft and rotatable therewith,
means for moving the shaft and disc toward the base for causing the disc to flatten the hamburger into a patty, a circular cup-shaped housing slidably telescoping over the disc with the rim of the housing depending below the latter and enclosing the disc, said housing receiving the hamburger when the housing is lowered, said disc being movable with respect to the housing for forcing the hamburger against the circular housing wall for forming a patty of uniform thickness and perfect circumference, the disc being arranged to raise the housing above the base when the shaft is retracted, and means for holding the housing against rotation at all times during its movement toward and away from the base, whereby the housing will be retained against turning as it is moved relative to the base.
2. In a device .of the type described, a double die for forming hamburger patties, one die being in the shape of a circular cup-shaped housing, means for raising this die above a support and for lowering it onto the support, means for preventing rotation of this die at all times during its movement toward and away from the support, whereby the cup-shaped die will be retained against turning as it is moved relative to the support, the other die being rotatable in the first die and movable axially with respect t0 the first die, the means for raising the first die also moving the second die axially, and means for rotating the second die for forming a patty on the support and confined within the two dies.
