Title: Safe power machine
Claims: What is claimed is: 1. A safe power machine comprising: a housing with walls forming a first slot having a thickness of no more than about three-eights inch at the surface of the housing to prevent the deep entrance of a human finger therein, said first slot extending substantially horizontally, said housing having a second slot substantially parallel to and vertically spaced from said first slot, a portion of one of said slots lying directly over the other slot and said slots extending into said housing from opposite sides of the housing; a motor mounted in said housing; a first machining tool drivingly coupled to said motor and located within said slot, said first machining tool including a saw with an upper portion extending through said first slot; and a second machining tool drivingly coupled to said motor and located within said second slot. 2. A safety power machine comprising: a housing having fixed walls forming a slot of a thickness of less than three-eights inch along the outside of the housing; a motor mounted in said housing; a cutting tool coupled to said motor to be rotated by it, said cutting tool extending through said slot to cut plates of material inserted into the slot, all rotating cutting surfaces of said tool which lie in said slot being spaced from the open edges of the slot by a distance at least equal to the thickness of the slot; a shaft driven by said motor, said cutting tool comprising a circular saw blade fixed to the shaft; a sanding disc fixed to said shaft at a location spaced from the saw blade; and a second slot provided in said housing, said second slot being less than three-eights inch in thickness and extending perpendicular to the shaft, said sanding disc being located at the bottom of said second slot. 3. A safety power machine comprising: a housing having a pair of vertically spaced slots extending substantially horizontally into opposite sides of the housing; a shaft rotatably mounted in said housing below said slots; a circular saw blade fixed to said shaft and having an edge portion extending across a first of said slots; and an elongated narrow saw coupled to said shaft to be moved by it, said narrow saw extending through a second of said slots. 4. The power machine described in claim 3 wherein: said housing forms a third slot at one side of the housing and extending parallel to said pair of slots; and including a sanding disc fixed to said shaft and located near the bottom of said third slot. 5. The power machine described in claim 3 wherein: said housing forms a third slot at one side of the housing and extending perpendicular to said pair of slots; and including spline means formed at an end of said shaft; a drill assembly slidably mounted on said shaft and engaged with said spline means, said assembly including a drill with a tip that is movable across said third slot when the assembly slides; and manually operable means for sliding said drill assembly; said housing including walls forming a drill-receiving recess on the side of the third slot opposite the shaft, for receiving the drill tip and prevent contact of an operator therewith.
