Patents by Inventor Robert A. Grubba

Robert A. Grubba has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7749040
    Abstract: A smoke production system for a model locomotive capable of accurately simulating the exhaust characteristics of an actual locomotive. The present invention accomplishes this by monitoring the rotation to the flywheel of the electric motor used to drive the drive wheels of the model locomotive. Various devices may be used to monitor the rotation of the flywheel. For example, a magnet is employed on the flywheel and a magnetically-reactive element such as a reed switch or Hall effect sensor is positioned adjacent to the flywheel. Alternatively, an opticoupler or cam may be used to track the rotations of the flywheel. A controller counts the rotations of the flywheel and actuates a smoke production device to emit smoke four discrete times for every rotation of the model locomotive's drive wheel.

  • Patent number: 7634411
    Abstract: A system for generating realistic train sounds which are synchronized with the motion of a model train. A sensor is placed aboard the model train to sense the position of desired components, such as the driving pistons of a model steam engine. Preferably, sound data is gathered and transmitted as a radio frequency signal from the model train. The radio frequency signal is received by an external receiver/amplifier. This component amplifies the synchronized sounds and plays them through a subwoofer which is capable of producing deep and resonant sound.

  • Patent number: 7215092
    Abstract: A wireless system uses a direct UHF radio frequency (RF) signal to control electric trains and train accessories. A controller, such as a handheld unit used by the toy train operator, accepts control commands and transmits encoded control data over a high frequency radio link directly to a receiver, on the toy train or train accessory, which decodes the commands and controls the toy train or toy train accessory functions with either unidirectional or bidirectional communication between the controller and the model train or train accessory. One controller has the ability to control many trains and other model train layout components such as signals and track switches even while other train operators are operating their trains on the same electric train track layout.

  • Patent number: 6485347
    Abstract: The present invention provides a smoke generator for a model train. The invention allows a toy locomotive to produce smoke as an actual train would, in a puffing pattern. The present achieves its purpose by manipulating the flow of air through a smoke generating housing with a fan and a blocking device.

  • Patent number: 6441570
    Abstract: The present invention provides a controller for a model toy train set. In a first aspect of the invention, the controller includes a plurality of input connectors for receiving supply power from one or more remote power supplies and providing such power to a plurality of output connectors. In a second aspect of the invention, the controller includes an input device for producing an input signal to limit the amount of output power supplied from the controller to a toy train set when the controller is remotely operated from a remote transmitter. In a third aspect of the invention, the controller includes a programming circuit having a first mode for controlling a plurality of output channels from separate sets of inputs and a second mode for controlling the plurality of output channels from a single set of inputs.

  • Patent number: 6186074
    Abstract: The present invention provides a drive assembly for a model toy train which connects a single drive shaft from an electric motor to a pair of discrete truck assemblies. The drive shaft drives a plurality of pinions which in turn drive a pair of worm shafts which extend toward the truck assemblies. A pair of worm wheel shafts are driven by the worm shafts to drive the wheels on the truck assemblies. A saddle and bearing combination rotationally connects the model toy train to the truck assemblies allowing the truck assemblies to freely rotate.
