Abstract

Abstract A horizontal-type band saw having a drive wheel and a support wheel mounted on a base, and a saw blade supported on the wheels, a work support member, and horizontally adjustable substantially vertically positioned guide means mounted one on each side of the work support member, each having a recess for receiving and guiding a portion of the saw blade in a vertical cutting position, and elongate channel-form blade guards each affixed at one end to one of said vertical blade guides and having the saw blade disposed within the channels of the blade guards, the other ends of the blade guards telescoping into protective housings covering the drive and support wheels. In an improved form, the walls and bottom of the channelform blade guards are sufficiently spaced from the blade guides so that the blade may be removed from the guides and blade guards without disassembling the structure. In a further improved embodiment, a hinged cover is provided on the blade guard to cover the open channel during operation, and to be opened for removal of the saw blade.
