Patent number: 11499283Abstract: A wheel guard includes a guard member disposed on a compactor wheel. The guard member has a first side having a first portion and a second portion. The second portion is offset from the first portion such that to define a first stepped recess therein. The guard member has a second side disposed opposite to the first side. The first portion has a first cross-sectional thickness and the second portion has a second cross-sectional thickness such that the second cross-sectional thickness is lesser than the first cross-sectional thickness. The guard member has a first top surface defined by the first portion, and a second top surface defined by the second portion and partially by the first portion. The second top surface is offset from the first top surface such that to define a second stepped recess therein. The wheel guard includes a base plate and a wear pad coupled thereto.Type: GrantFiled: April 13, 2020Date of Patent: November 15, 2022Assignee: Caterpillar Inc.Inventors: Dan Pierce, Jim Dale Angell, Thomas Marshall Congdon

Patent number: 7203773Abstract: A method and apparatus for using a control port in accordance with a variety of different protocols. A main processor communicates a configuration instruction to an interface controller. The interface controller uses the configuration instruction to select a protocol driver and to process signals to a control signal processor. The signals to the control signal processor include an output signal, an input signal, a direction signal, and a modulation enable signal. The control signal processor uses the direction signal to determine whether to output data or input data. The control signal processor uses the modulation enable signal to determine whether to couple a carrier signal on a transition from one digital level to another. The interface controller outputs data in accordance with a selected protocol and processes data input in accordance with the selected protocol.Type: GrantFiled: September 4, 2003Date of Patent: April 10, 2007Assignee: Digital Networks North America, Inc.Inventors: Jef Frank, Dan Pierce, Gerard Talatinian

Patent number: 6213574Abstract: A baseball dispenser for storing and dispensing a balls, comprising a cylindrical container which has an interior sized to hold a large supply of baseballs, softballs, and the like, and an opening at its top for receiving balls into the interior thereof. The baseball dispenser has a pair of handles secured to the upper end of the container and a pair of wheels rotatably mounted to the lower end thereof for facilitating easy transportation across the surface of the ground. One or more support columns extend vertically from the bottom of the container, wherein a compression spring is disposed about each of the support columns. A circular platform is vertically slidably disposed within the container and is engaged with the support columns such that the compression springs are constrained axially between the bottom of the container and the platform.Type: GrantFiled: August 7, 1998Date of Patent: April 10, 2001Inventor: Dan Pierce
