Emery Grinding, Buffing & Brushing Machine
The first engraving on this page represents a machine -which, in addition to possessing all the advantages of an efficient emery grinder, may also be used for buffing and brushing. This is done by an extension of the spindle upon which are placed the extra wheels as shown.
The object in designing this machine has been to furnish a desirable combination to factories and establishments which either cannot afford or have not the room for separate machines, to perform all the different operations. To use separate machines also involves extra expense and a sacrifice of power.
The body is cast in one piece, being built in a very substantial manner, having the bearings separated sufficiently to enable two men to work upon it at the same time. The spindle, which is 36" from the floor, carries two emery wheels, which may be either covered or solid. The extension referred to is removable, and carries a buffing wheel. Another removable tapered screw extension carries a brush.
These extensions, together with the main spindles, are of steel, and are fitted together so nicely that, when in motion, they run so true that one would suppose they were one solid piece of steel turned without removing from the centers.
The wheels may be left in place, or, in case they should interfere with a large piece of work, they may be removed in a few moments.
One of the principal advantages of this machine is that a piece of work may be ground, buffed and brushed with but one handling, and without stopping the machine to change the wheels. The operator simply has to step from one wheel to the other. There are six flanged sleeves for bushing wooden wheels furnished with each machine. The speed at the spindle should run is from 2,500 to 3,000, according to the diameter of the wheels.
the spindles is greatly facilitated by the addition of a graduated scale.
These machines are built by P. Pryibil, 401 to 467 West Fortieth St., N. Y. |
