New Surface Planing Machine
In designing the "Eureka" Surface Planing Machine, illustrated on this page, the makers, Cordesman, Egan & Co., 246 to 250 West Front Street, Cincinnati, Ohio, have aimed to squeeze a big machine into small compass, as a glance at its solid and compact proportions will show.
The machine will take a fine finishing cut, doing the smoothest work, or, by a few turns of the wheel, the bed can be lowered, and a cut 5/8 inch deep in hard wood can be taken. The frame and bed are each cast in one piece, and especial credit is claimed by the makers for the manner in which the bed and frame are dove-tailed together, making the machine very stiff, and leaving the cut free from ridges. The boxes for cylinder and rolls are cast on the machine, making a very rigid and substantial bearing free from vibration.
The cylinder is of refined wrought iron with twisted journals, and the bearings are long and lined with genuine Babbitt. A pressure bar goes on each side of the cylinder, thus insuring steadiness even when planing short or thin stuff. These pressure bars are self-adjusting, always regulating themselves to the various lumber being planed.
The process of changing the machine to different thicknesses is quick and simple, the bed being raised and lowered by a single hand wheel. The feed rolls and cylinder being in stationary boxes, are always the same, and when the bed is raised or lowered, a glance at an index on side shows the thickness to be planed, and requires no further setting.
The four feed rolls are extra-large, the front one being fluted. The friction rolls in table are easily adjustable. The gearing is strong, and every device introduced to make a strong, reliable feed.
It planes from 1/16 to 6 inches thick, and either 18 inches or 24 inches wide. A counter shaft is furnished, if needed, and can be either placed on the floor, or under, as most convenient. The counter shaft has a flanged pulley on it to run to loose and tight on machine, thus stopping or starting the feed.
The machine is especially recommended by its makers for panel work, cigar box, pattern and mill work, box and planing mills, carriage and furniture factories, and smooth work generally. The pulleys are 10 inches by 5½ inches face and are intended to run at the rate of 900 revolutions per minute. Two sizes are made of this machine, 18¼ and 24¼ inches wide respectively, working in either soft or hard wood. |
