Abstract
An improved dimpler attachment for use on gypsum wall board and the like for fastening on a fastener driving tool. The tool housing has a driving piston, pneumatic or other power means to reciprocate the piston and an elongated driver connected to the piston for reciprocation and extending out of the housing. A slide connects a dimpler head to the outside of the housing and bears a fastener magazine. The dimpler head has a central channel slidingly engaging the driver and a pocket adapted to functionally seat a stop plug connected to the driver. The head is connected to the housing by return springs. The front end of the head is curved so that it effects a dimpling action when urged forward on the slide by the forward movement of the plug while seated in the pocket during forward movement of the driver. The driver front end preferably is chamfered to facilitate stripping of fasteners from the magazine and preferably is curved to match the head so as to effect flush seating of a fastener in the hole of a dimple made in a substrate during operation of the tool. The dimpler attachment comprises the described head, slide, return springs and driver which are readily attachable to conven…
