ABSTRACT:
A combination tip wrench and stand which is particularly designed for use with a soldering or desoldering instrument, but having other uses. Basically the tip wrench is of generally U-shape, consisting of a top wall and two side walls, preferably of sheet metal. The instrument has a first, a second, and a third width of successively smaller dimensions, the largest width being at one end. The top wall extends only from the second width and is provided with a first U-shaped opening. The other end also has a second U-shaped opening in the top wall, thus forming a first, a second, and a third wrench. Near the third U-shaped opening is a portion normal to the top wall and the side walls and integral therewith and having a circular opening to extend, for example, a soldering tip therethrough, while its nut can be unscrewed by engagement with the side walls. The instrument also includes a pair of legs which in their folded position extend over the smallest width of the tip wrench. The two legs are yieldably held by a tension spring extending through apertures in the side walls. The ends of the legs near the spring include a portion normal to the legs, so shaped as to lock the legs against the side walls and also, in the extended position, to lock the legs against the width of the side walls, thereby to form a stand for an instrument.
