SPECIFICATION forming part of Letters Patent N o. 571,564, dated November 17, 1896. Application filed Mey 18, 1898. Serial No. 592,041.l (No model.)
Be it known that I, EDWARD J. HOFFMAN,
a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Glass-Polishing Machines, of which the following is a specification.
The object of this invention is to rotate a head carrying a series of polishers, also to impart a rotary movement 'to'each polisher independent of the rotation of the head.'
The further object of this invention is to automatically reciprocate a' table or series of tables supporting the glass plate to be polished.
ln the accompanying drawings, Figure 1 is a front elevation of a series of polishers and tables, the tables being shown in lengthwise vertical section. Fig. 2 is a plan View of the head supporting the polishers. Fig. 3 is-a vertical section on dotted line a, Fig. 2..
The main supporting frame consists of lengthwise beams 1, supporting a rail 2 upon their upper faces and held elevated by posts 3, to which is secured a lengthwise beam 4.
Upon the rails 2 are located tables 5, supported upon wheels 6 and adapted to be moved in the lengthwisefdirectionfofthe rails, each table supporting 'a ymovable board 7, upon which the glass plates 8 tobe polished are located. v
Above the main supporting-frame is supported a framework composed of lengthwise barslOQ, held supported by vertical supporters i Over each table is located a head support# ing polishers, to which movement is imparted by a vertical shaft 11, held supported in bearJ ings connected to the lengthwise bars, and a pulley 12, supported by each shaft, around which a belt passes connected to a prime mover, imparts a rotary movement to the shafts in the direction indicated by the arrows. A weight 13 is located on the upper end of the shaftfurnishingthe necessary pressure for the polishers. The shaft 1,1 at the right hand of Fig. 1 supports a pulley 14, which has a connection with 'a pulley 15, supported by a vertical shaft 16, by a belt 17, and a.
pulley 18 is supported by a shaft 16,'4 which has a connection with a pulley 19, supported by a shaft 20, by ay belt 21. f This shaft 20 has f a crank-arm 2v2, connectedwto its upper end,
to which a link 23 is pivotallyl connected, and to the other end of the link is pivotally connected a -bar 24, whichv is guided in loops 25, connected to the ends of the movable tables, and set-screws clamp the loops in connection with the bar, thus forming a connection hetween-each of the tables and with the vertical shaft 11, andas the crank-'arm is rotated end, and toothed wheel 30 is secured to this' shaft and located on the upper face of the head. In each of the other openings` 28 is located a shaft 31, having a toothed wheel 32 secured to its upper end and-to its lower'end is secured a polisher The teeth of these toothed 'wheels meshwith the teeth of the center toothed wheel and will rotate in the direction indicated by the arrow thereon upon the center toothed wheel being rotated.
Apolisher of the above construction is connected-to each ofthe vertical shafts 1l, which is lowered in contact with the glass plate to be polished, and upon the rotation of the, shafts arotary movement will be imparted to each ofthe polisher-shafts and to the pol-A ishers, and the head 26 will be rotated in the `'same direction as the vertical shaft, but at a reduced speed, thereby imparting to each polisher a rotary movement, also a bodily-rotary movement around the shaft, and as the table supporting the glass plate to be polished is reciprocated under the polisher. a great extent of surface may be polished.
I claim as my invention- In a glass-polishing machine,the combina tion of a vertically-rotatable shaft, a head loosely supported thereby, aseries of polish ers loosely supported by the head and agear connection between the polishers and the -rotataiole shaft.
