Single V Iron Planer
But few real improvements have been made in iron planers in the last ten years, and most of the prominent tool builders in the country use the same patterns, and build their planers the same way now as they did ten and fifteen years ago, while lathes, drill presses and milling machines have been greatly improved. The planer, one of the most important tools, has been left in almost its primitive state.
We illustrate herewith a cross section view of an improved iron planer made by Newton & Cox, Cleveland, O. The principal improvement consists in use of but one V while other manufacturers use two. The belt shifting apparatus is greatly improved and simplified. One V is made and scraped to a surfacing straight edge; this is made perfectly true with itself, then the flat part is surfaced with a plate, making it a smooth plane surface. The V then serves as a guide to the carriage. This is calculated to be far preferable to the old method of two V's & as all practical mechanics know that it is impossible to do perfect work on a planer. Valve-seats and bearing surfaces of fine tools always have to be scraped to a surface plate to bring them to perfect bearings. The principal cause of this is the two V's which are never perfect, and the imperfections cause the bed to " roll." Single V Iron Planer.
Four planers have already been built on this plan, and some time since the necessary papers to cover an improved lubricating device with the carriage that keeps it constantly oiled when in motion. |
