TBUING MECHANISM FOR GLASS-GRINDING APPARATUS.
Application filed November 14, 1911.
Specification of Letters Patent.
To all whom. it may cmwcrn Be it known that T, RAYMOND C. llna'r'rr, a citizen of the United States, residing at Ford City, in the county of Armstrong and State of Pennsylvania, have invented certain new and useful Improvements in Truing lricchanism for Glass-Grinding i pparatus, of which the following is a specification.
This invention has reference to glass grinding apparatus and particularly to the operating mechanism for truing the grinding tables. It has among its chief objects: the provision of an improved arrangenwnt of driving mechansm whereby the grinding tables may be turned or trued in place by means of a cutting tool; and the provision of an arrangement oi the character described whereby a plurality of grinding tables may be turned or trued on the same apl'iaratus. These, together with such other objects as may hereinafter appear or are incidental to my invention 1 attain by means of a construction illustrated in preferred form in the accompanying drawings.
Of the drawings Figure 1 is a diagrammatic illustration of a number of grinding machines such as may be found in glassmaking factories; Fig. 2 is a plan view of such a grinding machine drawn on a larger scale and showing my improved arrangement of parts; Fig. 8 is a section through Fig. 2; Figs. 4tand 5 illustrate details of my improved mechanism; and Figs. 6 and 7 are respectively a plan and side elevation of the cutting tool carriage employed in turning the grinding tables.
Referring to Fig. 1, it will be seen that a number of grinding pits 1 are illustrated. Mounted in the pits are the usual grinding tables 2 over which the runners 3 are supported from the beams 4 mounted on the walls of the pit. For convenience in handling the grinding tables 2, which are o't considerable weight, tracks 5 are provided which lead from each pitto a main track 6 which in turn may be provided, if desired, with a number of turn-tables 7. If preferred, a transfer car may be utilized to shift the table from one machine to another. In theleft-hand pit of Figurel I have shown the apparatus with the runners 3 removed, and a finishing or cutting mechanism detachably secured to the beam 1; for turning down and finishing the surface oi. the grinding table.
011 reference to Figs. 2 and 3, particularly to the latter, it will be observed that the operatingor driving mechanism for revolving the grinding table comprises a vertical shaft 1) slidably mounted in the pit for vertical movement. The shaft is rotatably driven by the motor 10 through the train of gearing indicated by the numeral. 11. The shaft is elevated and lowered by means o'l a hydraulic plunger mechanism 12 and is locked in raised position by means of the forked block '13 (Figs. 4; and 5) which advanced bcncath the flange 1 oil? the plunger when the latter is elevated, by the hydraulic device 15. The end of the shaft 9 has a bearing on the under side of the grinding table and when it is elevated it carries the latter with it free from the tracks 5 when both shaft and table can be rotated. hen thus elevated, the surface of the grinding tables is brought adjacent the cutting mechanism 8 and the cutting tool 16 thereof is properly adjusted. As the grinding table is rotated, the tool 1.6 is advanced across the face of the table by means 01 the motor and gear connections shown in Figs. 6 and 7 The advantage of the construction where there are a number of: grinding pits is obvious. The runner mechanism is not only emnbersome but di'flicult to remove, and the various grinding tables can be brought to the pit to which the cutting mechanism is attached and there be turned or trued and then brought back to their proper pits. The construction is also advantageous in that it is preferable to turn the tables in place inasmuch as a large amount of time and labor is required in moving the tables to a shop or the like because of the weight and size of the tables. Other advantages will occur to those familiar with the art.
Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is the following 1. In glass grinding apparatus, the combination of a group of grinding machines having portable tables, a truing machine for facing oil the surface of any of said tables, and a permanent transfer means connecting
