CROSS REFERENCE TO RELATED APPLICATION
This application is a divisional patent application of its copending parent patent application, Ser. No. 265,037, filed Oct. 31, 1988, now U.S. Pat. No. 4,843,198.
1. Field of the Invention
This invention relates to a new combination of a burner control device and an electrical switch unit carried by the device as well as to a new control device for such a combination, a new switch unit for such a combination and to new methods of making the same, the burner control device being adapted to control the flow of gaseous fuel to a top burner of a cooking apparatus or the like and the electrical switch unit being adapted to control the electrical ignition means for initially igniting the fuel issuing from the burner.
2. Prior Art Statement
It is known to provide a combination of a burner control device having a rotatable shaft and an electrical switch unit carried by the device and being operated by the selector shaft, the device having a cover secured thereto by a plurality of screws each having a head and the switch unit having a plurality of cavities therein respectively receiving the heads of the screws therein. For example, see the U.S. Pat. No. 4,249,047 to Huff et al.
Also see the U.S. Pat. No. 4,342,886 to Demi, which discloses a switch unit that is snap-fitted to a burner control device.
It is one feature of this invention to provide unique means for securing an electrical switch unit to a burner control device.
In particular, it was found according to the teachings of this invention that by modifying the conventional screws utilized for normally holding a cover to a burner control device, such modified screws can be utilized for snap-fitting to snap-fit means of an electrical switch unit that is to be carried by the device and be operated by the selector shaft thereof whereby such screws provide the dual function of securing the cover to the burner control device and securing the electrical switch unit to the burner control device.
For example, one embodiment of this invention provides a combination of a burner control device having a rotatable selector shaft and an electrical switch unit carried by the device and being operated by the selector shaft, the device having a cover secured thereto by a plurality of screws each having a head, the switch unit having a plurality of cavities therein respectively receiving the heads of the screws therein, at least one of the cavities having snap-fit means therein that is snap-fitted to its respective head to hold the switch unit to the device.
Accordingly, it is an object of this invention to provide a new combination of a burner control device and an electrical switch unit, the combination of this invention having one or more of the novel features of this invention as set forth above or hereinafter shown or described.
Another object of this invention is to provide a new method of making such a combination, the method of this invention having one or more of the novel features of this invention as set forth above or hereinafter shown or described.
Another object of this invention is to provide a new burner control device for carrying an electrical switch unit, the device of this invention having one or more of the novel features of this invention as set forth above or hereinafter shown or described.
Another object of this invention is to provide a new method of making such a burner control device, the method of this invention having one or more of the novel features of this invention as set forth above or hereinafter shown or described.
Another object of this invention is to provide a new electrical switch unit to be carried by a burner control device, the electrical switch unit of this invention having one or more of the novel features of this invention as set forth above or hereinafter shown or described.
Another object of this invention is to provide a new method of making such an electrical switch unit, the method of this invention having one or more of the novel features of this invention as set forth above or hereinafter shown or described.
Other objects, uses and advantages of this invention are apparent from a reading of this description which proceeds with reference to the accompanying drawings forming a part thereof and wherein:
