MELOHIOR MALEVEZ, OF BRUSSELS, BELGIUM, ASSIGNOR TO MESSIEURS PILKINGTON BROTHERS, OF ST. HELENS, ENGLAND.
APPARATUS FOR GRINDING, SMOOTHING, AND POLISHING GLASS.
SPECIFICATION forming part of Letters Patent No. 449,686, dated April '7, 1891.
Application filed October 23, 1890- Serial No. 369,021. (No model.) Patented in Belgium August 22. 1886, No- 74,333 in Eng land April 23, 1888, No. 6,028,: in Germany November 14, 1888, No. 48,725, and in Italy January 9, 1890,1I0. 2,675.
To all whom it may concern:
Be it known that I, I\IELCHIOR MALEVEZ, of Brussels, in the Kingdom of Belgium, have invented a new and useful Improvement in Apparatus for Grinding, Smoothing, and P01- 1 ishin g Glass, (for which I have obtained Letters Patent in Belgium, No. 74,333, dated August 22, 1886, and Patent of Addition No. 78,563, dated August 22, 1887; in Great'Britain, No. 6,028, dated April23, 1888; in Germany, No. 48,725, dated November 14, 1888, and in Italy, No. 26,757, dated January 9, 1890, and nowhere else and I do hereby declare the following to be a full, clear, and exact description thereof.
The invention relates to apparatus for grinding, smoothing, and polishing glass, more especially plate-glass.
The main objects are to so construct such apparatus that the glass is operated on uniformly and effectually by the grinding, smoothing, and polishing disks or rubbers.
Figure 1 is a plan. Fig. 2 is a vertical section at the line A A, part being in elevation; and Fig. 3 isan end view of my improved apparatus.
1 represents the foundation of brick-work or other suitable material.
2 is a table on which the glass to be ground, smoothed, or polished is secured in any usual manner. The said table is carried on a vertical shaft 3 free to rotate in bearings 4.
5 is a worm-wheel freed from or connected to the shaft 3 by means of a clutch 6. This clutch maybe of any usual form. The wormwheel 5 is actuated by a worm on a shaft 7, carried in bearings 8, which worm is not shown, because behind and meshing with said worm-wheel. (See Fig. 2. Motion is given to the worm-wheel shaft 7 by means of a belt 9, passing around pulleys 011 the said wormwheel shaft 7 and main driving-shaft 10.
The main driving-shaft 10 is actuated by any convenient motor through fast and loose pulleys ll. The frames 12 are provided each with three bearings 13, through which pass shafts 14. The central shafts are driven directly from the main driving-shaft 1 O by bevel gear 15, while the outer shafts are driven from the central shafts by means of toothed wheels 16 on the said shafts and intermediate toothed wheels 17, secured to axles 18, free to revolve in bearings 19. In this way all the shafts M rotate in the same direction. The upper ends of the shafts 14 have secured thereto cranks 20, and the lower ends are free to rotate in bearings 21. The cranks 20 are provided with pins 22, which fit into bearings in three beams 23, one crank being at the end of each beam. The said beams are connected together by tie-bars 24, disposed so as to radiate at angles of about sixty degrees from the center of the middle beam. Beneath the middle beam and the tie-bars are six frames 25, suspended by means of screw-shafts 26, the lower ends of which pass through nuts 27 in the frames 25. The upper ends of the said screw-shafts are provided with beveltoothed wheels 28, and are carried in bearings 29,,secur'ed to the beams and tie-bars. The shafts 30 are carried in bearings 31 on the beams and tie-bars, and are provided with operating hand-wheels and with bevel-toothed wheels 33, which gear into the wheels 28 on the screw-shafts 26. The grinding, smoothing, or polishing disks orrubbers 34 are shown as not fixed to and carried by the frame; but. they are provided with pins 35, which fit loosely and freely in slots 36 in the frames 25, to move with such frames horizontally and downwardly, but not upwardly. The slots 36 are disposed in the frames 25, that the grinding, smoothing, or polishing disks or rubbers are arranged in more or less concentric circles.
The action of the apparatus is as follows: The glass to be ground, smoothed, or polished is secured on the table 2 in any usual mannor, the frames first having been raised close to the beams and tie-bars by means of the screw-shafts 26, actuated through the hand-wheels 32 and shafts and their gear. Suitable grinding, smoothing, or polishing disks or rubbers 341 are placed next on the glass with their pins in alignment with the slots in the frames 25, and then the frames 25 are lowered until the bins of the grinding, smoothing, or polishing disks or rubbers engage in the slots 36. The main shaft 10 is now set in motion, and the glass being acted on is rotated with the table 2, while the disks or rubbers have a circular or orbital motion imparted to them by means of the cranks 20 acting on the beams, tie-bars, and frames.
The motion of the table 2 may be arrested at pleasure by means of .the clutch 6.
I claim-- 1. Grinding, smoothing, and polishing apparatus for glass, consisting of a table 2 and means to rotate it, in combination with beams 93, bars 24, which tic said beams together, radiating frames 25, screw-shafts 26, connecting the frames and beams and tie-bars, and gearing for operating the said screw-shafts to raise and lower the frames and crank-shafts, cranks thereon connected to the beams, and power appliances to drive all of the crankshafts simultaneously and in one direction,
thereby to impart a circular or orbital motion to the frames and their rubbers, substantially as described.
2. Grinding, smoothing, and polishing apparatus for glass, consisting of a table 2 and means to rotate it, in combination with beams 23, bars 24:, tying said beams together, radiating frames 25, suspended from said beams and tie-bars, rubbers arranged concentrically upon said frames and crank-shafts, cranks thereon connected to the beams, and power appliances to drive all of the crank-shafts simultaneously and in one direction, thereby to impart a circular or orbital motion to the frames and their rubbers, substantially as described.
