  • Patent number: 6155249
    Abstract: The present invention entails a gas log set including a generally triangular shaped pan having front and rear portions and a pair of sides that extend generally rearwardly and inwardly from the front portion. Each side of the triangular shaped pan includes a cantilevered log support structure projecting outwardly therefrom for receiving and holding artificial logs. In addition, other artificial logs provided with the set are supported such that they extend into the pan itself.

  • Patent number: 4502463
    Abstract: The present invention relates to an improved method and apparatus for efficiently capturing heat generated by gas logs and distributing the heat produced thereby into selected areas of a structure. In a fireplace environment having gas logs therein, the present invention entails a duct structure extending generally over the gas logs. A fan is provided adjacent the back wall and floor of the fireplace communicating with an inlet end of the duct structure. The fan produces a system of forced air which is introduced into the duct structure and moved therethrough. As the system of forced air passes through the duct structure it is heated by the gas logs underlying the duct structure, and the heated forced air is then exhausted from the duct into an adjoining structure.

  • Patent number: 4432337
    Abstract: The present invention relates to a method and apparatus for efficiently capturing heat generated by a fuel source such as gas or gas logs and distributing the heat produced thereby into selected areas of a structure. In a fireplace environment having gas logs therein, the present invention entails a duct structure extending generally over the gas logs. A fan is provided about an inlet end of the duct structure and produces a primary system of forced air that is introduced into the duct structure and moved therethrough, generally over the gas logs within the fireplace. In an area overlying the gas logs, the duct structure is provided with an opening and a transverse restrictor plate disposed within the duct adjacent the opening. As the system of forced air passes the restricted area, warm or hot air heated by the gas logs underlying the duct structure is induced into the duct structure where the same combines with the already produced system of air passing through the duct structure.

  • Patent number: 4206857
    Abstract: The present invention relates to an improved agricultural distributor including a hopper having a side wall structure and bottom and a plurality of spaced apart openings provided therein for dispensing material from said hopper. A cam type rotary flow control plate is rotatively secured to the bottom of said hopper adjacent said openings for simultaneously controlling the flow rate of material from said hopper by controlling the effective opening area of respective openings. Provided within said hopper is a plurality of spaced apart gear wheels that are rotatively driven during the operation of the distributor such that the gear wheels generally agitate the material within the hopper and also serve to generally deliver and meter material to and through said openings.
