<p>1,114,168. Soldering. ERSA ERNST SACHS KOMM GES. 12 Jan., 1966 [13 Jan., 1965], No. 1509/66. Heading B3R. An electric soldering iron comprises a heating element and a soldering bit mounted on a tubular shank which is handless and is secured in a block carrying connecing terminals and a cable clamp and adjustably pivotally connected between cheek plates of a carrying member. In one embodiment a bit 1, Fig. 1, and element 2 are carried on a tubular shank 3 which is secured by a cap nut 4 in a hollow block 5 having flat sides 5<SP>1</SP> and a transverse bore 13. Internally of the block is arranged a clamping element 8 which clamps the cable 10 and provides connection to the two leads 12 of the element, the cable extending from the end of the block remote from the shank 3. The block is arranged between the side cheeks of a trough-like carrying member 20, Fig. 2, a spindle passing through holes in the cheeks and the bore 13 and having a clamping nut at one end. The block may be adjusted in the member 20 about the spindle and clamped in position. In another embodiment the block is adjustably mounted on a spindle as before in the cheeks (22a), Fig. 6 (not shown), of a short bifurcated member in turn pivotally mounted on a spindle between cheeks of a head (29) clamped to a stand (45). A lever (32) is mounted on the two spindles so that the block, adjusted and clamped in the bifurcated member, may be brought to soldering position by depressing the lever. A compression spring (34) is provided to act on the bifurcated member and encloses a cable connected to a pedal which may alternatively be used to lower the iron.</p> |
