Patent number: 4785725Abstract: An improved automatic french frying machine and method uses a supply of cooking oil which remains in a cooking vat during normal operation and is heated directly in the cooking vat. A system of thermostats combines with a heating element within the cooking vat to ensure proper cooking temperature and safe operation. An automatic initialization and monitoring system ensures safe startup and operation. Preferred embodiments also include an automatic flushing cycle which is activated at predetermined intervals to clean the cooking vat and replenish the cooking oil within the vat. A specially shaped cooking vat ensures that food particles will be removed from the vat during the flushing cycle. Oil degradation is minimized by either an open-topped cooking vat or a cooking vat having a lid which remains open during cooking.Type: GrantFiled: February 27, 1986Date of Patent: November 22, 1988Assignee: U1 GroupInventors: Maurice Tate, Robert L.

Patent number: 4776296Abstract: A knob for a cooking vessel is a whistle which gives an audible signal that cooking temperature has been reached, and has a valve slide assembly including a separate leaf spring for shutting off the whistle. Inside and outside knob parts incorporate halves of a resonance chamber which makes the knob extremely simple to mold, assemble, clean, and disassemble. The inner knob is comprised of two parts: a top having a whistle orifice and a base which has two arc segments portions which extend through the lid of a cooking vessel and allow the top to be snapped into place abutting the cooking vessel lid. Because the inner knob is comprised of two parts in this fashion, the central opening in the cooking vessel top can be made small enough so that it will be difficult for a user to catch his or her fingers in the opening when the knob is dissasembled for cleaning. The valve slide rests in guides and is overlaid by a knob cover.Type: GrantFiled: February 9, 1987Date of Patent: October 11, 1988Assignee: Regal Ware, Inc.Inventor: Thomas W. Heermans

Patent number: 4690095Abstract: A cooking vessel is provided with a whistle knob which has an internal passage for carrying steam from a hole in the cooking vessel to a rotary whistle chamber molded in the knob. The whistle chamber is displaced from and eccentric to the knob axis. The lower surface of the knob has a cavity which surrounds the knob axis, providing a steam passage inlet which is in communication with the hole in the cooking vessel regardless of the angular position of the knob relative to its axis. From the inlet cavity, steam passes through a vertically extending passage, a plenum chamber and a horizontally extending passage which introduces steam into the whistle chamber at an angle which causes an audible whistle and rotary movement of the steam. The whistle chamber has an outlet which may be opened and closed by rotational movement of a valve ring which extends circumferentially around the knob.Type: GrantFiled: May 19, 1986Date of Patent: September 1, 1987Assignee: TSCO CorporationInventors: Henry M.

Patent number: 4417508Abstract: A wafer baking oven has a set of baking tongs which move through the oven to effect baking of the wafers. The oven is particularly for wafer products such as flat wafers, low hollow wafers, sugar cones, wafer cups and wafer figures. There is a baking chamber through which the baking tongs move and a front end at which baked wafers are discharged from the baking tongs and fresh batter is poured into the tongs for baking. The region in which this takes place is referred to as a front port. The front port includes a batter pouring station and a discharge station with a chute and at least one discharge spider. To reduce loss of heat and to reduce the noise level of the wafer oven, the front port is surrounded by a housing which comprises, at least in part, an enclosure attached to a frame. The housing has two passage openings at the side which face the baking chamber, and the baking tongs pass through these passage openings as they move in a circuit between the baking oven and the front port.Type: GrantFiled: May 11, 1982Date of Patent: November 29, 1983Inventors: Franz Haas, Sr., Franz Haas, Jr., Johann Haas

The drive and safety cut-out are provided housed within the heater housing adjacent the frying tank of the machine for ease of assembly and manufacturing cost. The heater element housing is mounted on pivots which allow easy pivotal removal of the heating elements from the frying tank as well as providing a wide stance support for the heating elements when pivoted out of the tank. The drive and control circuitry for the conveyor and the cutter head are interlocked to prevent repetitive cycling of the cutter head during a conveyor overload position. An improved dual head doughnut cutter is also provided.Type: GrantFiled: April 28, 1980Date of Patent: August 31, 1982Assignee: Belshaw Bros., Inc.Inventors: Wilbur D. Wilke, Archie A.

Patent number: 4089222Abstract: There is disclosed a device for telemetry of the temperature of a mass undergoing temperature change, typically of a comestible being heated in an oven, and the like. The device includes a probe having a cavity which receives a thermally expansive material such as wax, a displacement member responsive to pressure developed by the temperature expansive material, a sonic or ultra-sonic signal generator, a latch mechanism inhibiting operation of the audio signal generator and a rod mechanically interconnecting the displacement member with the latch so that expansion of the material in the probe cavity trips the latch mechanism to permit generation of an output signal. The device also includes adjustment means for variation in the relative positions of the latch mechanism to the displaceable member whereby the triggering temperature for the latch mechanism can be fixedly adjusted.Type: GrantFiled: December 30, 1976Date of Patent: May 16, 1978Assignee: Robertshaw Controls CompanyInventor: Charles H.

Patent number: 4083250Abstract: A portable food thermometer affording an audible alarm at a preset cooking completion temperature. A water reservoir defined within a two-part housing is fillable by the user in advance of use. An elongated sensing probe insertable in the food is secured extending through one of the housing parts inward of the reservoir and contains a slideable rod supported on a confined temperature sensing material. Expansion of the sensing material in response to increasing food temperature forces the rod outward of the probe. Opposite the free end of the rod is a spring loaded ball valve sealing the reservoir from a whistle outlet. Temperature graduations on the housing enable adjusting the spacing between the rod and valve at room temperature for presetting the operating temperature of the unit. On reaching set point cooking temperature, the outwardly forced position of the rod acts to open the valve enabling steam in the reservoir to activate the whistle alarm.Type: GrantFiled: February 10, 1977Date of Patent: April 11, 1978Assignee: Dresser Industries, Inc.Inventors: Randall Goff, John M. Radbill, Roger W. Pleasanton
