Patents by Inventor Christopher Trimble

Christopher Trimble 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: 12123174
    Abstract: A hydraulic control system for use with a work machine. The work machine has a platform which supports an operator. When the operator is not on the platform, the platform moves into a first position, causing a signal generator to send a signal to a controller. The controller is configured to limit the hydraulic flow to the ground drive motor when the platform is in the first position. The controller may directly reduce operation of the engine, or may adjust a valve which diverts a portion of hydraulic flow. The limitation may be overridden when desired by the operator.

  • Publication number: 20240059352
    Abstract: An articulated work machine with individually powered drive members. Each drive member is controlled by a corresponding electric motor, and is capable of rotating at a different speed and in the opposite rotational direction than all other drive members. Each drive member may also remain stationary while all other drive members rotate. The electric motors are commanded by a controller, which may be directed by inputs from by an operator. A lift arm extends from the front end of the vehicle, and a platform station extends from the rear end of the vehicle. The lift arm is connected to a tool, such as a bucket.

  • Patent number: 11767656
    Abstract: A cruise control system for work machines. The system comprises one or more levers for controlling the velocity of the work machine and one or more magnet assemblies. The magnet assemblies comprise means of overcoming the neutral bias of a control lever so that the velocity of the work machine may be maintained without manual input from the operator. The magnets may act directly upon a control lever or a surface adjacent a control lever. Additional controls may be employed to set a maximum cruising speed for the work machine when cruise control is engaged.
