Abstract: A biscuit joiner 11 has a pair of selectively usable retractable antiskid pin subassemblies 13, 15 for increasing the frictional resistance of the shoe assembly 23 with a workpiece when making a cut in the workpiece. Pins 19, 21 are biased forwardly to an extended position by a spring 45. To permit selective use of the pins 19, 21, a retractor 47 retains pins 19, 21 in a retracted position. Retractor 47 preferably comprises a cam 59 and a cam follower 61 and is actuated and deactuated by rotation of pins 19, 21 within chambers 43. Each pin tip 55 has a plurality of peripheral points 73-76 which are particularly effective for reducing skidding on a workpiece.

Abstract: An accessory for inflating and deflating inflatable articles comprises a conduit 13, an intake 17, an outtake 19 and an injector 35. In use, conduit 13 functions as a venturi tube for rapid inflation and deflation of inflatable articles, preferably, articles having a large, low pressure air volume. For inflation, outtake 19 is connected to the inflatable article. For deflation, intake 17 is connected to the inflated article. For inflation and deflation, a source of pressurized air, preferably, an electric air compressor is connected to injector 35.

Abstract: A control apparatus for a battery pack having two power receptacles coupled to an electric circuit that includes a switch for selectively delivering power to the receptacles. The control apparatus includes (1) a structure for retaining the receptacles a predetermined distance apart; (2) a cover moveable on the retaining structure so as to selectively expose a selected one of the receptacles while simultaneously covering the nonselected one; and (3) a protuberance coupled to the cover for engaging the switch and translating movement of the cover into operable movement of the switch.

Abstract: A simple, low cost, light weight biscuit jointer (21) comprises an elongated motor housing (23), a motor end cap assembly (25) fixed to one end of housing (23) and a base assembly (27) for engagement with a workpiece. To form a biscuit receiving slot in a workpiece, the motor housing (23) and end cap assembly (25) are pivoted relative to base assembly (27) for sweeping a an elongated, generally cylindrical bit (29) through an opening (31) in a base plate (33). The sweeping action is effected by an operator rotating a handle (35) fixed to end cap assembly (25) counterclockwise (FIG. 2) relative to base assembly (27). A handle (37) is used to stabilize base assembly (27) as house assembly (23) is pivoted to form the slot.

Abstract: A biscuit jointer cutter for making segment shaped cuts by plunge cutting has a shoe assembly reciprocally movable relative to a housing containing a motor. The shoe assembly houses a cutter blade rotatably driven by the motor, and has a front opening through which the blade is movable in a forward direction for cutting and retractable in a rearward direction after cutting. A fence assembly is mounted on the shoe assembly above the front opening. The fence assembly is adjustably movable upwardly and downwardly relative to the front opening by means of a rack and pinion mechanism, and also has a fence adjustably pivotable through 90 degrees. A depth of cut adjustment mechanism is operatively connected between the shoe assembly and the housing, and includes a movable rod cooperative with a stop. The stop is a turret selectively rotatable about an axis eccentric of the rod and having recesses of different axial length.
