Description

TECHNICAL FIELD

The present invention relates to tortilla cutters. More particularly, the present invention relates to an automatic cutter that is able to cut stacked tortillas.

BACKGROUND ART

Numerous innovations for tortilla cutters have been provided in the prior art that are described as follows. Even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present invention as hereinafter contrasted.

In U.S. Pat. No. 5,148,655, titled Slicer and Bagger for Substantially Flat Food Products, invented by Salinas, stacks of food products are manually placed on top of a slicing blade and a slotted ram vertically positioned above the stack pushes the stack through the blade into a bag below the blade. The drawback of this device is its complexity and the inability to automate the cutting operation.

In U.S. Pat. No. 5,918,533, titled Tortilla Manufacturing Apparatus, invented by Lawrence et al., a system for making tortillas includes a sheeter, a roller/heater, and an oven. Tortillas are die cut into an oblong shape in the sheeter. The roller/heater rolls the tortillas into a round shape and conductively heats the tortillas simultaneously on the top and bottom surfaces, gelatinizing the food product and sealing in moisture. The tortillas are then baked in an oven. Slot marks on the tortillas are avoided as the roller/heater has upper and lower belts have continuous surfaces.

In U.S. Pat. No 4,978,548, titled Method and Apparatus for Continuous Production of Tortilla Chips, invented by Lawrence et al., the method includes steps of mixing tortilla flour and water to form a dough, rolling the dough into a continuous sheet, cutting tortilla shapes from the sheet, moving the tortilla shapes continuously through a baking oven to produce baked products, moving the baked products continuously along an equilibration conveyor to substantially equalize the moisture content of each baked product throughout the product to form an equilibrated product, moving the equilibrated product continuously through a refrigeration unit to cool the product to form a cooled product, cutting the cooled products into chip shapes, and moving the chip shapes to a fryer to produce the tortilla chips. The frying step may be continuous or batch as desired.

In U.S. Pat. No 5,662,949, titled Tortilla Manufacturing Apparatus, invented by Rubio et al., embodiments of this invention useful for removing articles cut from a sheet of flexible material include a gas transmissive conveyor belt that is brought into proximity to the exposed surface of the articles, a suction roll which backs the conveyor belt and has an internal vacuum and passageways for exposing said vacuum to the outer surface of the suction roll in configurations corresponding the leading portions of the articles, and means for causing the passageways to register substantially with the leading regions of the articles. Embodiments may also include passageways which are arcuately arrayed in groups, a cylindrical cutter roll for cutting out the articles from the sheet as it is being transported by a carrier surface, and/or a carrier surface in the form of a roll face.

Numerous innovations for a tortilla cutter have been provided in the prior art that are adapted to be used. Even though these innovations may be suitable for the specific individual purposes to which they address, they would not be suitable for the purposes of the present invention as heretofore described.

SUMMARY OF THE INVENTION

When the housing bracket is designed in accordance with the present invention, it has a housing bracket top having a housing bracket top left opening and a housing bracket top right opening, a housing bracket middle, a housing bracket bottom with a housing bracket bottom left opening (not shown) and a housing bracket bottom right opening (not shown).

In accordance with another feature of the present invention, the right housing having a right housing wall with a right housing wall slot, a right housing top rib with a right housing top rib opening and a right housing top rib notch, a right housing middle rib with a right housing middle rib opening and a right housing middle rib notch, a right housing bottom rib with a right housing bottom rib opening and a right housing bottom rib notch, a right housing connector with a right housing connector first opening and a right housing connector second opening.

Another feature of the present invention is that the cutter has a cutter first blade and a cutter second blade, a cutter shaft, a cutter plate, a cutter plate first opening, and a cutter plate second opening.

The novel features which are considered characteristic for the invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of the specific embodiments when read and understood in connection with the accompanying drawings.

In operation of tortilla cutter ( 10 ), the housing shaft ( 12 E) and concurrently the sharp cutter blade is retracted and a stack ( 16 ) of at least one tortilla is positioned within the opened housing ( 12 ), as shown in FIG. 5 A. The housing shaft ( 12 E) is then extended closing the housing ( 12 ), and the cutter shaft ( 14 C) is extended forming at least one severed tortilla ( 16 A), as shown in FIG. 5 B. The housing shaft ( 12 E) is then retracted, the cutter plate ( 14 D) is retracted exposing base plate opening ( 15 A), and the stack ( 16 ) of at least one severed tortilla ( 16 A) falls through base plate opening ( 15 A) into container ( 18 ).

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the type described above.

While the invention has been illustrated and described as embodied in a tortilla cutter, it is not intended to be limited to the details shown, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
