Not illustrated. 1903 Excerpt: ...lengths, and farther allow of any one or more being easily removed in the event of their being damaged. The connectors themselves are cut from sheet copper, insulated by wrappings of tape or silk, and, after being bent to shape, are collected together by a device which clamps the complete set for one end of the armature. The Kapp connector, fig. 81, permits the over-all length of the armature to be kept down, but is somewhat wasteful of copper in cutting. The lugs are bent up and down respectively at right angles to the connector, the angular length of which is the mean of the front and back pitches, and the requisite increase or reduction is obtained by bending the lugs. The set is built up on a channel-shaped rim (shown in fig. 68), carefully lined with insulation, round which the connectors pass spirally in such a way that while the lugs at one end are attached to short-ended armature bars, those at the other are soldered to bars with prolonged ends; an outer layer of insulation and binding wires prevents any dislocation. A form which, with small modifications in the clamping hub, is widely employed, is shown in fig. 82. In this the strips are bent in opposite direction, making connection with long and short ended bars, while the complete set may form a compact overlapping mass, or have a more open structure, according to the radial depth at disposal. A similar connector, obtained by the folding of continuous strips, is shown in fig. 83. The Fig. 83. construction of the supporting! hubs will be sufficiently apparent from figs. 84 and 85. The simplest method of attaching the armature bars and connector strips is to solder the latter in saw cuts in the bars; but a better, though more laborious, way is to fold the lugs round the bars and solder. Somewhat in...
