Abstract:
A microtome comprising:a knife holder and a knife holder support having cooperating arcuate bearing surfaces permitting angular movement of the knife holder relative to the knife holder support about the axis of curvature of said bearing surfaces with concomitant sliding movement of one of said arcuate surfaces over the other; a releaseable securing means operable to pull the knife holder against the knife holder support and thereby to fixedly secure the knife holder on the knife holder support, wherein the releaseable securing means is releaseable to allow angular movement of the knife holder relative to the knife holder support; and a locating device adjustably secured to one of the knife holder and knife holder support, and a datum being provided on the other of the knife holder and knife holder support for cooperation with said locating device, such that said locating device engages in said datum to ensure that with said locating device fixed to said one of said knife holder and knife holder support the angular position of the knife holder on the knife holder support at which said locating device cooperates with said datum can readily be established, and said locating device can be fixed in such adjusted position independently of whether or not said releaseable securing means is released or whether or not the knife holder is removed from the knife holder support.
