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.

Abstract: A coffee brewing unit is disclosed which enables a brew cycle to be initiated automatically upon insertion of a coffee receiving vessel into its coffee receiving position, but which prevents a brew cycle from proceeding if a number of required operating conditions are not implemented. If all operating conditions again become implemented after a brew cycle, once underway, is interrupted, the brew cycle continues on to completion. Visual signals indicate that a brew cycle is in progress and also when sufficient mineral deposits are present that cleaning of the unit is recommended. An insulated carafe is used as the vessel to receive brewed coffee thereby eliminating the need for a warmer plate. The unit may be mounted under a cabinet to thereby maximize usable countertop space and a coffee basket for the unit utilizes a dispensing valve which is opened by the carafe when inserted into position but which closes when the carafe is withdrawn.

Abstract: A coffee brewing machine utilizes an insulated carafe to receive the brewed coffee and automatically turns itself off a short time after completion of a brew cycle. The machine also turns off automatically a specified time after a brew cycle is initiated when calcification is so extreme that flow of water through the unit is totally prevented. Additionally, as a safety feature, the system also turns off automatically in the case of a "dry run", that is, a short specified time after accidental energization when no water is in the reservoir. A lamp is lighted when a brew cycle is in progress but is extinguished at other times.

Abstract: For a coffee brewing machine, an indicating system which operates to notify the user when it is time to clean the water supply conduit of accumulated mineral deposits. When a self contained removable reservoir is inserted into its operative position connecting to the water supply conduit, it closes the contacts of a temperature sensitive switch. During normal operation, the switch opens when water is depleted from the reservoir and the brewing cycle is completed. However, if the switch opens while water remains in the supply conduit upstream of the heater mechanism, this is a sure indication that there is a substantial accumulation of mineral deposits in the supply conduit. Thus, a sensing mechanism is employed to detect the presence of water in the supply conduit after the temperature sensitive switch opens, and a lamp is energized to indicate the condition. In one embodiment, the sensing operation is performed by an electromechanical device, and in another embodiment by logic circuitry.

Abstract: A peeler attachment for an electric appliance includes a frame having a central slot therein and a blade disposed centrally of the slot. The blade includes first and second cutting edges at opposed sides thereof. The cutting edges are spaced from the central slot to form first and second entry channels into the slot. The blade includes first and second surfaces facing the slot shaped to provide continuously increasing exit channels whereby any tendency for peelings to become wedged in the exit channels is avoided. A shank for locking the peeler attachment into the electric appliance is preferably unitary with the blade. First and second locking notches in the shank permit installation of the peeler attachment in first and second rotational positions angularly separated by 180 degrees, whereby both right-handed and left-handed user are accommodated.

Abstract: A contact includes an arcuately-shaped member having opposite end portions which are joined by an intermediate U-shaped portion. The end portions are slotted to form bifurcations which include contact-engaging surfaces. A contact element includes elongated first and second portions which are joined by an intermediate portion. A lanced-out tab is formed in, and forms an acute angle with, the first portion with the tab opening toward the intermediate portion.

Abstract: An electric knife having a housing, a motor fixed in the housing having a drive shaft disposed for rotation about a drive axis, a spur gear fixed to the end of the drive shaft, a flange fixed to the motor including an integrally formed, axially-projecting output shaft coaxial to an output axis and parallel to the drive axis, an output gear in meshing engagement with and driven by the spur gear disposed on the output shaft for rotation about the output axis, a tubular element coaxially engaging the output gear for rotation therewith about the output axis, the tubular element including a cylindrical cam in the outside surface thereof, and a pair of blade holders disposed in the housing in adjacent, opposed relation for independent, linear reciprocation parallel to and on opposite sides of the output axis.

Abstract: An electric mixer for selectively rotating a pair of cooperating beaters, the mixer comprising a housing defining a cavity having an axis extending between first and second ends thereof, a motor disposed in the cavity generally coaxial with the cavity axis, the motor including an axial drive shaft and a drive gear fixed to the second end of the drive shaft, a gear case fixed to the second end of the motor, the gear case including a pair of integral, depending tubular shafts having rotation axes substantially parallel to each other and to the cavity axis, each tubular shaft having a bore open at the first and second ends thereof.

Abstract: Two pairs of contact strips are mounted on the respective bridge members of an integral web portion of the molded field case of a power tool or other motor-driven device. The forward ends of the contact strips are cantilever mounted and automatically engage the respective terminals on the field, as the field is inserted into the field case and is secured therein. An annular wire harness is mounted on the rear bearing boss of the field case. Spaced contacts are carried by the wire harness and engage the respective ends of the first pair of contact strips. The respective ends of the second pair of contact strips are connected to terminals on the ends of the brush shunts. In a reversing embodiment, a third pair of contact strips is mounted on the bridge, and a rotatable reversing subassembly is mounted on the rear bearing boss in lieu of the wire harness.
