New Iron Planer
The illustration on this page represents a new iron planer which is made from very heavy patterns, and which embodies some newly patented features. The first noticeable peculiarity is that the parts subjected to the greatest strains are made of unusual size. The bed has great depth and sufficient length to prevent the table from tipping when heavily loaded on the overhanging end. The table is thick, with slot bolts truly planed, and pin holes carefully reamed for convenience in fastening work.
The uprights or posts are very heavy and stiff, having great breadth of base, making it possible to take heavy cuts when the bar is at greatest height from table, without jar or chatter. The uprights are designed to allow the greatest possible amount of light on work.
To enable it to plane surfaces truly, and without chattering, the machine is provided with a powerful train of cut gears, a cut rack on the table, also with shafts of large diameter with bearings double the usual length.
The patented feeding device gives automatic feed in all directions, is adjustable from fine to very wide cuts for finishing, and takes no power except when feeding.
The crank for operating the cross feed by hand can be applied to end of the rod in bar, thus operating the vertical and angular feeds by hand when the handle on the perpendicular feed screw is not within easy reach.
To return the table after the cut, in quickest practical time, can best be effected by open and cross belts, and pulleys of different diameters on countershaft, thus dispensing with extra gears. Speed can be increased or diminished by users to meet their requirements by changing the countershaft pulleys.
The patented automatic belt-shifter transfers but one belt at the same time, thereby preventing two belts running in opposite directions from being on the tight pulley at same time, thus obviating "squealing" of belts and jar of machine. It is entirely disconnected from feeding apparatus, hence works easily, giving the operator quick and perfect control over movements of the table without using the countershaft shipper; is arranged to throw out to clear the reversing dogs on the table which can then be run backward to examine the work. The dogs, not being loosened, retain the necessary strokes and also allow a temporary adjustment of stroke to places not in the limit fixed by the position of the dogs.
This new planer is one of the latest machines brought out at the machine tool works of David W. Pond. Worcester, Mass. |
