20080244913 | Tool having clamping chuck - A tool includes a shank having an engaging hole for receiving one end of a tool member and having a number of orifices for receiving detents, a control ferrule rotatably engaged onto the shank and having a number of notches each of which includes a deeper portion for selectively receiving the detents and for disengaging the detents from the tool member and a shallower portion for selectively forcing and actuating the detents to engage with the tool member and to detachably couple the tool member to the shank, and a spring member may actuate the shallower portions of the notches of the control ferrule to engage with the detents and then to detachably couple the tool member to the shank. | 10-09-2008 |
20090199410 | Impact tool with multiple and simultaneous force vectors - The present invention is directed to a tool for modifying or interacting with a surface wherein two simultaneous force vectors are applied to the tool so as to control the resulting effect of the tool. In particular, the tool is comprised of a handle, a shaft having a proximal and a distal end, a working face, and a strike plate. The handle is connected to the proximal end of the shaft wherein the shaft has a finite length. At the distal end of the shaft is a working face which may be either integral to the shaft or is a separate element which is durably attached to the shaft. At a point on the shaft between the proximal or handle end, and the distal or working face end, a strike plate is durably attached to the shaft. The strike plate is configured to receiving repeated impact by a drive source. Suitable drive sources include, but are not limited to, manually operated discontinuous devices such as weighted head or dead-blow type hammers as well as continuous service devices such as pneumatic and electrically powered impact hammers. In practical application, an operator applies at least one force vector (FV | 08-13-2009 |
20100218384 | Cutting tool - The cutting tool includes a rigid, elongate, axially and laterally symmetrical bar having a plurality of parallel cutting edges and a handle portion at each end thereof. The tool has a plurality of cutting blades having generally flat faces therebetween. The edges are blunted at each end of the tool to allow the end portions to serve as handles, thus facilitating manipulation of the tool. Each handle portion includes at least one flat face that is coplanar with a face extending from at least one cutting edge. This allows the tool to be stroked along a panel surface to trim a veneer edge therefrom with the plane of the cutting blade remaining flush against the surface of the panel during the cutting operation and not being lifted from the surface due to the thickness of the handle protruding beyond the plane of the cutting blade. | 09-02-2010 |
20110041346 | CHISEL WITH INTERCHANGEABLE BLADE - A chisel with interchangeable blade has a handle, a holding device and a blade. The handle has two ends and a device hole. The device hole is defined in one end of the handle. The holding device is securely mounted in the device hole and has a body. The body is securely mounted in and protrudes out from the device hole and has a connecting end and a connecting hole. The connecting end protrudes out from the device hole. The connecting hole is defined in the connecting end of the body and has a cross section. The blade is detachably mounted on the holding device and has a connecting tang. The connecting tang is detachably mounted in the connecting hole and has a cross section corresponding to that of the connecting hole. | 02-24-2011 |
20110247218 | WOOD CHISEL AND BLADE FOR A WOOD CHISEL - A tool, in particular a wood chisel, includes a first profiled part ( | 10-13-2011 |
20140137415 | ACCESSORY FOR A RECIPROCATING SAW - An accessory for a reciprocating power tool including a first blade clamp mechanism and a linkage having a first end and a second end. The accessory further includes an attachment member coupled to the first blade clamp mechanism and to the first end of the linkage. The attachment member couples the linkage to the tool. A shaft is secured to the second end of the linkage and includes a second blade clamp mechanism. A distal member is coupled to the power tool and defines a channel through which the shaft extends. The channel defines a first stop surface and a second stop surface. A biasing mechanism is contained within the distal member and supported by one of the first and second stop surfaces. The biasing mechanism biases the shaft in a first position. | 05-22-2014 |
20150020390 | WOOD CHISEL AND BLADE FOR A WOOD CHISEL - A tool, in particular a wood chisel, includes a first profiled part ( | 01-22-2015 |
20160158928 | Self-Contained Force Magnifying Chisel - The self-contained force magnifying chisel disclosed herein includes a chisel portion, a striker, at least a portion of which is disposed within the chisel portion, and a spring, a least a portion of which is disposed within the chisel portion. The spring attaches to both the chisel portion and the striker. When the striker is pulled by a user, the spring stores mechanical energy. When the user releases the striker, the striker impacts on the chisel portion transferring the mechanical energy stored in the spring into a driving force. The force is magnified by a chisel blade on the chisel portion of the self-contained force magnifying chisel and applied to a workpiece. | 06-09-2016 |

20120255180 | CHISEL BLADE WITH SIDES CONFIGURED FOR CUTTING - A chisel includes a blade joined with a handle configured to be struck by a striking instrument. The blade includes a front beveled cutting edge portion at its forward end, a beveled side cutting edge portion along one longitudinal side of the blade, and a strike surface along an opposite, longitudinal side. The blade also has a main body portion that narrows in thickness as it extends in a forward direction from a relatively rearward portion thereof to the front beveled cutting edge portion and that narrows in thickness as it extends in a lateral direction from the strike surface towards the beveled side cutting edge portion. The beveled side cutting edge portion has a surface forms an angle with a surface of the main body portion. | 10-11-2012 |
20120272530 | MULTI-EDGE CHISEL - A multi-edge chisel which can be operated in a hands-free manner is made from a unitary main body with at least one opening. The main body has a flat profile, with a blade on one end, and at least one striking plate on the opposite end. | 11-01-2012 |
