The accompanying illustration represents a new and improved upright drill press, designed and manufactured by Mr. W. P. Davis, of North Bloomfield, N. Y., and which is characterized by a number of mechanical features which render it a highly convenient and efficient tool for the machine shop. Its special features will be understood from the following description.
The drill has a 4.5-inch column, and wil swing 20 inches on the face-plate. The diameter of the face-plate is 14 inches. The weight of the sleeve and face-plate is accurately balanced by a counter weight inside the column, and attached to it by a chain passing over a pulley at the top of the column. By pushing down or raising up the handle, therefore, the sleeve and face-plate may readily be raised and lowered. The spindle is of steel, and is held in an arm that is made to swing over the same as a planer head, thus making it possible to drill work at any required angle. The table can be swung around the column, and also turned on the sleeve, if desired, so that the tool will drill at any point on the face-plate without requiring the work to be readjusted. The drill is provided with a screw-feed or hand-wheel, which has a brass nut, and the spindle is connected to the screw with a brass cap nut. Each drill is provided with a chuck, adapted for the Morse taper shank drills, but any other can be fitted to it. The gears are cut, the spindles and screws are made of steel, and the sleeve is made to fasten with the handle by clamping to the column.
In connection with the screw-feed, this drill has a lever-feed for small quick drilling and counter-sinking, by the use of which, on many jobs, double the amount of work can be turned off than can be done with the ordinary screw-feed. The drill is provided with counter shaft, pulleys, hangers, belt-shifter and hanger-plank complete, ready to attach at once.
In the design and construction of this machine, it has been the effort fo the maker to produce a tool of reasonable price which should be capable of turning out accurate work, and which should be characterized especially by its simplicity and ease of manipulation.
From the foregoing description, our mechanical readers will be able to judge how completely the claims of the maker are realized. |
