A rectangular cavity is provided in an actuator lever intersecting with an upper edge of a shaft-receiving hole in the lever and receives a linearly slidable hard metal rectangular key having a cam on one edge for clamping the lever to the shaft. A screw engages threads on the key and is slidable with the key to a position where a distal end of the key is flush with or projects from a side surface of the lever, at which position the cam is free of the shaft-receiving opening, the key providing visual indication that the lever assembly may be positioned over the shaft without interference.

An improved optical sensor includes a light source from which light is projected onto an object. A photodetector detects the light reflected from the object. A refraction element is movable relative to the photodetector to vary the range of the optical sensor. The position of the light source relative to the photodetector can be varied.

A chip removal method and apparatus for a sign engraving machine. The method involves engraving a sign blank in such a manner that chips fall from a cutting region on the sign blank into an enclosure, and swirling the chips in the enclosure so that the chips exhaust through an opening in the periphery of the enclosure and eventually pass through a chute into a receptacle. The apparatus is a guide member located parallel to an outer envelope of the volume that can be occupied by a rotating cutting head of the engraver. The guide member has a surface for contacting the sign blank. The contact surface has an access opening at its center to allow chips to enter the guide member from a cutting region on the sign blank. The guide member tapers away from the cutting region and has an exhaust opening and chute for exhausting the chips. The guide member is used with a rotating cutting head that propels chips circumferentially and allows them to be exhausted through the chute.

A method and apparatus for automatic line width adjustment for engraving characters on a piece of sign material utilizes two cutters sliding by each other in face-to-face opposing relationship. Line width is controlled by controlling the spacing between a pair of cutter tips. The two cutters are moved over a portion of a sign blank while being rotated with the selected spacing between the cutter tips to effect a selected cutting width. The cutters are held in holders and are replaceable when worn out. An internal ratchet-and-pawl mechanism provides fifteen different cutter line widths. The cutter head is moved into engagement with an external pawl mechanism to operate the internal ratchet-and-pawl mechanism.

A pipemarker consists of an elongated sign, which has a front face for bearing identifying information and a rear face with a bracket-receiving channel, and at least one bracket that can be attached to a pipe with strapping. The bracket includes a rachet for tightening the strapping and an outward projection containing a compression spring which snaps into the bracket-receiving channel of the sign.

A high-speed impact hammer type solenoid capable of operating at high speed such as 500 to 1000 strokes per second and with a relatively long stroke length. It is housed in a cylindrical shell and includes two separate coils and magnetic circuits operating on a single short plunger. The plunger is driven magnetically in both directions. The short plunger has reduced mass. This is made possible by elongated backstops extending through the coils to the plunger and by a flux washer extending from the shell to the plunger. Close control of the plunger stroke is achieved by a non-magnetic sleeve surrounding the plunger and spacing the backstops which are screw threaded into the shell. Resilient anti-residual pads on each side of the plunger absorb the impact of the plunger with the backstop, start the plunger in the opposite direction and speed up the decay of the magnetic field.

A pair of replaceable, identical cutter inserts are provided for a cutter head assembly of a sign engraving machine. The cutter inserts have inside edges formed at an angle of approximately 15.degree. from a cutter tip axis. The inside edges of the cutter insert overlap to form an 'X' when installed in the cutter head for sign engraving operations. Chips migrate up the inside edges from the cutter tips and are exhausted from the cutting area.

A microprocessor controlled signmaking machine (1) including a reciprocating plunger (210) that impacts adhesive sheet material (46, 46a-d) to form a sign (48) including one or more characters separable from the sheet material (46, 46a-d) that can be adhered to the surface of an object.

Adhesive sheet material (10) for signmaking machines including a carrier tape (20), a release liner (16) and a sign tape (21,21') between the carrier tape (20) and release liner (16). Either the carrier tape (20) or release liner (16) has a high degree of elongation, and characters are defined in the sign tape (21, 21') by contacting the high elongation carrier tape (20) or release liner (16) with a character-forming tool of a signmaking machine.

A lockout device for a valve having a lever handle. The device includes a channel member defining a channel to receive a section of the lever handle when closed and a leg that bears against the valve or pipeline connected to it. A lock is inserted through the apertures in the channel member alongside an edge of the handle.
