An improve microtomy device is disclosed comprising a microtome and a thermostatically controlled refrigeration means controllable by a microprocessor and accommodated in an instrument cabinet, the improvement comprising, providing an upper part of the instrument cabinet in the form of a movable cover, which cover encloses a slidable transparent pane arranged above the microtome to define an inspection window disposed in a front portion of the cover. The pane is heatable and can be removed from the cover and/or shifted into a rearward portion of the cover to open the inspection window for cleaning purposes. The improved device provides convenient accessibility to the interior of the instrument and improved control of operations.

A guide arrangement for portable power saws is made up of a guide plate adapted to be placed on the work and a stand plate fixed to the saw. The guide plate possesses a raised rail running in the feed direction of the saw. In use, the saw with the stand plate is placed on the guide plate so that a socket in the stand plate fits round the rail and the stand plate may then be moved along the guide plate on the rail, the guiding section straddling the rail and guiding the stand plate on the rail. The stand plate is fitted with a backlash limiter having an operating part acting against the side of the rail for reducing play between the rail and the stand plate. This means that the saw is guided in the length direction parallel to the rail of the guide plate and it is possible for straight cuts to be sawn with a high degree of accuracy without any danger of the saw running askew. The backlash limiter may take the form of a spring loaded member or one driven by a screw or threaded rod. Alternatively the member may have a slot to allow adjustment thereof in relation to the rail.

A compass saw comprises a drive unit for a saw blade holder carrying a saw blade, and a base plate supporting the drive unit. The base plate has on its underside a glide shoe lined on a bottom face with a contact sole. The guide shoe is provided to guide the blade at the level of the base plate, more particularly close above the contact sole, laterally to an extract such as to prevent it from deviating from the desired course, as well from canting and coming into off position.

A guide device for a hand circular saw or the like has a guide plate with a non-slip coating on its lower face to make contact with the work, and a foot plate running along the guide plate and carrying the saw or the like thereon. The foot plate has a recess thereon which enables it to completely straddle the guide plate while giving lateral guidance. In the recess there are spring loaded rollers or shoes pressing on the guide plate.

A router comprises a cage supporting a drive unit having a shaft on which a cutter can be fixed. A rest plate is provided with an aperture for moving the cutter therethrough. The rest plate is connected to the cage through two guide columns on which it is displaceable in axial directions of the cutter and arrestable in a selected position. The rest plate is a hollow structure open downwardly where it is closed by a detachable cover having a smooth outer surface. A cavity of the plate communicates with and encircles the aperture 21 for the cutter and grows toward an exhaust connection which extends tangentially to the cutter, i.e. in the direction in which the millings are thrown. The exhaust connection can be connected to an exhauster. Laterally on the rest plate, an adjustable slide stop may be provided having an angled leg which can be brought into a position flush with the bottom surface of the rest plate or moved downward therefrom. A chip screen is mounted for adjustable movement toward and away from the rest plate.

Router with dust exhaust

The spindle can be rotated by way of a set wheel, and thus displaced within the spindle guide. At the end of this displacement, the spindle butts against one of the set screws of a turret stop provided on the rest plate. The spindle can be locked to the respective set screw by way of a swing extension. The spindle may be hollow to pass therethrough a tool and finely adjust the set screw already locked to the spindle.
