A cigar lighter has a heating element and a movable knob biased by a spring. The heating element has a first electrical terminal in contact with a first contact element disposed around the perimeter of the heating element and a second centrally located terminal in contact with a centrally disposed fastener. A bimetal element is in contact with the second terminal of the heating element and has two engaging clips. A movable contact moves with the knob and has a first position wherein it does not engage the clips and the heating element is unenergized and a second position wherein it engages the clips to energize the heating element.

A rivet pulling head is supported for vertical displacement from an up position to a down riveting position. A rivet delivery device is carried by a movable support and has a delivery arm which can be lowered relative to the pulling head and pivoted underneath it to deliver the next rivet to the pulling head. The delivery device is operated when the head is at the up position and while the head is maintained at that location.

Table top rivet setting assembly

A rivet tool is supported for repeated displacement to a rivet setting location. When the tool is at this location, it is forcefully pushed against the workpiece during rivet setting to assure that the rivet will be properly set.

A vacuum pulls a spent mandrel through a gun bore and into a collection tube which discharges into a collector. Gun operation and mandrel entry into and departure from the collection tube are sensed and blockage of the mandrel within the collection tube and the jamming of the mandrel in the rivet gun are determined and signalled to the operator. The cycle immediately continues when the mandrel is cleared.

Automatic riveting machine

Rivets are delivered from a feed chute to a transfer location and blown through a feed tube to a loading device. The presence of a rivet is sensed both at the transfer location and at the loading device and a fault indicator is operated in the event a rivet sensed and transported from the transfer location does not wind up in the loading device. The operator hits the reset button which blows clean air thru the feed tube in an attempt to free the jammed rivet. In the event this does not occur, the system assumes the operator cleared the jam and loads the next rivet into position to be transferred and continues the cycle.

An automatic riveting machine is disclosed which counts the rivets, as set, to control the feeding of rivets from a feeder to the rivet track or chute. The track will be resupplied after a selected number of rivets are set or sooner should the track become prematurely empty by removal of rivets from the track.

Apparatus and method for automated and semi-automated installation of blind rivets, comprising mechanical, pneumatic, and electronic subassemblies, with self-diagnostic capabilities. The system includes a rivet transfer arm external to the installation tool, which receives pneumatically fed rivets in a 'home' position and transfers the rivets to an 'advanced' position of alignment with the tool's nosepiece. A mandrel collection system routes separated mandrels from the tool to a remote receptacle through a channel under vacuum. Various sensors detect rivet placements, mechanism positions, and air pressure conditions, and signals from such sensors together with user inputs are received by a central processing unit (CPU). The CPU diagnoses the state of the installation system, produces command signals for a plurality of solenoid valves to regulate the system pneumatics, and reports status and fault conditions to the operator. The operating software may include self-correction routines, as for example one which recognizes unsuccessful loading of a rivet into the nosepiece and reattempts loading with a new rivet.
