Abstract: A pen is provided for the exterior of an animal shelter house or calf hutch, and is mounted onto an adjustable universal frame that fits on the exterior of the animal shelter house and is secured to the house. The frame is adjustable in width using cross members that overlap and are secured together in an adjusted position. The frame provides vertically extending guides that form a track for receiving side walls of the pen so that the pen can be slid longitudinally of the animal shelter house from an extended position which provides an exercise area pen to a retracted position wherein a forward panel of the pen will close the door or opening in the end of the animal shelter house. The end wall of the pen supports a suitable holder for feeding buckets for the calf or young animal.

Abstract: A warming and drying housing is provided with a support wall for the animal that will place the animal in a position where clean, heated air can be passed over the animal for drying and warming a newborn animal. The housing can have a support formed as a shelf that can be slid in and out of the housing, or the housing can have other types of openings, such as hinged doors or hinged side panels that open to permit access. A transport cart for the animals can be coordinated with the type of housing being used so that an animal can be transported in the cart, washed and partially dried in the cart if desired, and then moved into the warming and drying housing easily.

Abstract: The present invention relates to an animal shelter having a baffled entrance. Snow and rain are kept out of the shelter by the baffled entrance while air is free to circulate into the shelter. A movable attached pen is provided in which the animal may exercise.

Abstract: The hand control mechanism has the ability to receive two alternative modes of input for the given mode of output. The mechanism includes a handled lever extending into a housing rotatably mounted to a frame, and a bell crank rotatably mounted to said housing. The handled lever can be moved longitudinally to a first or second position. The first position communicates the lever to a plurality of gears such that rotating the lever about its longitudinal axis rotates the bell crank about the housing. Placing the lever in the second position the bell crank is restrained from rotating free of the housing which can be rotated directly by the lever, rotation of the bell crank being the assigned mode of output.
