New Power Feed Hand Planer.
We present in Fig. 7 of the illustrations a general view of a new power feed hand planer, which is manufactured by the Bentel & Margedant Company of Hamilton, Ohio, and for which many claims are made. In referring to the novel feed apparatus of the machine the manufacturers point out that it retains all the advantages of the sensitive hand feed, while it has none of the disadvantages; that it is elastic and sensitive like the hand, but differs from it because the feed is conunuous and the application of pressure uniform, that number of pieces can be fed at the same time, and that the whole width of the table can be filled up with narrow material, and the pieces fed in an unbroken line. Another important advantage which is claimed for the machine is that no expert operator is required to lay the material within the grip of the feed works, as an intelligent boy answers for this purpose. The manufacturers state that they have had such a decided success in applying this form of planer to various work formerly done by hand that they have constructed a greatly improved machine, which is strong and is supplied with a positive and powerful feeding apparatus, as an inspection of the engraving will readily show. The journal boxes support two large and wide face adjustable feed pulleys, any number of which can be placed on the shafts within the dimensions of the machine. The pulleys are flanged and carry heavy India rubber bands with wide face, traveling from one to the opposite feed pulley. The lower flat parts of the band from the vertical center lines of pulleys rest on the material and adjust themselves to any inequalities of surface and move it in regular speed of motion forward over and past the planer cutter head. The amount of pressure for the reception of various thicknesses of material is adjustable, and the tables can be raised or lowered regardless of the feed apparatus. The machine is of substantial construction, the column frame being cast in one piece and provided with a top declining in angle on both sides. Bach side carries a dovetailing slide bolted to the frame proper. The tables are long and heavy and arranged with inclined sides all cast in one piece, while the lower part is planed with dovetail slide surfaces and provided with adjustable slide gibs.
