International Classification:

B25C 1/04

US Classification:

227 8, 227129, 227142

Abstract:

A fastening tool can include a housing and a motor assembly in the housing. The motor assembly can include an output member and a motor for translating the output member. A knob can be rotatably coupled to the housing and include a first surface. An adjustment element can have a second surface and a threaded aperture. The second surface can be engaged to the first surface such that rotation of the knob effects corresponding rotation of the adjustment element. An adjustment rod can be threadably received into the threaded aperture. A lower contact trip can be coupled to the adjustment rod. A locating formation can be coupled to one of the housing and the knob. An indexing member can be coupled to the other of the housing and the knob. The indexing member can engage the locating formation to resist rotation of the knob relative to the housing.

International Classification:

B25C 5/02

US Classification:

173131, 227133, 227131

Abstract:

A method for calibrating a power tool having a roller, a driver and a solenoid. The solenoid has a body and a rod and is coupled to the roller so as to be capable of selectively advancing the roller toward the driver. The method includes: locating the roller onto a predetermined portion of the driver; moving the body of the solenoid in a first direction until the occurrence of a first predetermined condition, the first direction being in a direction that causes the roller to be driven toward the driver; after the occurrence of the first predetermined condition, moving the body of the solenoid in a second direction opposite the first direction until the occurrence of a second predetermined condition and thereafter securing the body of the solenoid to inhibit further movement of the body of the solenoid.

International Classification:

B25C 5/15
B25C 1/06

US Classification:

227131, 227 4, 227120

Abstract:

A fastening device drives one or more fasteners into a workpiece. The fastening device generally includes a tool housing and a multistage solenoid having at least a first stage, a second stage and an armature member that travels therebetween. The multistage solenoid is contained within the tool housing. A driver blade is connected to the armature member. The driver blade is operable between an extended condition and a retracted condition. A control module determines a position of the armature member relative to at least one of the first stage, the second stage and a combination thereof. A trigger assembly is connected to the control module and activates a driver sequence that moves the driver blade member between the retracted condition and the extended condition. The control module directs power between the first stage and the second stage based on the position of the armature member relative thereto.
