초록 ▼

A pneumatically operated fastener-driving tool, particularly adapted for nailing drywall to the framing of a building, comprising a housing, a reciprocator assembly mounted within the housing, and a piston mechanism mounted within the reciprocator assembly for axially driving the fastener into the drywall and underlying framing member. Upon actuation of the tool, the piston is pneumatically driven through a fastener-driving stroke and the reciprocator is reactively driven in an opposite direction. The oppositely driven reciprocator assembly absorbs recoil energy during the piston\s driving stroke without transmitting an appreciable amount thereof to the housing, thereby substantially precluding housing recoil during driving of the fastener. At the end of the driving stroke, the reciprocator engages and is decelerated by the piston, thereby reducing housing recoil subsequent to the driving of the fastener. At the end of its driving stroke, the piston mechanism recesses the fastener in the drywall and engages a dimpler member to form a shallow recess around the driven fastener.

A fastener driving tool comprising: (a) a housing; (b) a reciprocator assembly mounted for linear movement within said housing; (c) means for pneumatically driving fasteners in a single strokes into a workpiece, at least a portion of said fastener driving means being mounted within said reciprocator assembly for parallel linear movement relative thereto; (d) means for pneumatically actuating said fastener driving means forwardly through a driving stroke and simultaneously reactively actuating said reciprocator assembly rearwardly within said housing whereby rearward recoil of said housing during said driving stroke is substantially eliminated; (e) means carried by said reciprocator assembly for cooperating with said fastener driving means by impingement therewith to dissipate recoil energy of said reciprocator assembly with but slight impingement of said reciprocator assembly upon said housing, whereby rearward recoil of said housing subsequent to said driving stroke is significantly reduced; and (f) dimpler means for forming a rounded dimple in a workpeice as the fastener is being driven thereinto, said dimple circumscribing the driven fastener wherein said dimpler means include an elongated dimple member carried by said housing for a limited longitudinal movement parallel to said linear movement of said reciprocator assembly, said dimple member having an inner end positioned to be struck by said fastener driving means during said driving stroke, and a tapered outer end positioned to be driven into a workpeice to from said dimple, said outer end of said dimple member having a workpeice engaging surface having two areas making two respectively distinctly different angles with the axis of movement of said dimple member, whereby uniform dimples may be formed despite tilting of said tool and the axis of movement of said fastener driving means relative to the surface of a workpeice in which a dimple is to be formed. A fastener driving and dimpling apparatus adapted to drive a fastener and make a dimple therearound in the absence of metal-to-metal impacts between any parts of the apparatus, said apparatus comprising: (a) an outer housing; (b) piston means mounted in said housing, said piston means being adapted to engage a fastener and drive it into a workpiece; (c) fluid-operated means to actuate said piston means in such manner as to drive said fastener fully into the workpiece in a single stroke; (d) dimpler means having an inner end, and also having an outer end adapted to contact and dimple the workpiece; (e) first resilient bumper means provided at said inner end and adapted to be engaged by said piston means so that said dimpler means is actuated; and (f) second resilient bumper means disposed outwardly of an intermediate portion of said dimpler means and inwardly of a portion of said housing.
