GLASS-GRINDING TABLE.
Specification of Letters Patent.
Patented Dec. 15, 1914.
Be it known that l, lewaia) BaoNALL, a citizen o'l' the United States. residing at Pittsburgh. in the county of Allegheny and State ol Pennsylvanii, have iniented certain new and useful linproi'muents in (Erlass- Grinding Tables, of which the following is a specification. f
My invention relates to iuiproveinents' in apparatus for grinding, smoothing and polishing plate glass, and it has tor its object to provide effective and economical means for cusliionincr and holding the glass plates upon 'the upper portion olf the rotating),` table, in connection with. the oper-ations peilbi'iiied by the usual superimposed runners.
In carrying out my invention the rotatable supporting table is provided with means for exhausting the air trom its interior, and a plurality of numerous supporting resilient cups, the central portions of which are in communication with such vacuum cavity, adapted to support the plate or plates and hold them by suction, or exterior air pressure, the cups being so constructed as to utiliz/.e automatically closing check valve devices .tor preventingr ingress of air through the exposed cups.
Preferred constructions ot' the invention are shown in the accompanying drawings, in which- Figurelis a. plan View of the apparatus, showing' certain of the exposedcups provided withinelosinp` valve devices. l'-`i,q.2is a ver tical sectional view tln'fough the table, showing the glass supliorted upon sonne ot the cups bet'ore air exhaustion is effected. Fig. 3 is a sectional detail view oi a portion ot' the table, showing the plate resting on the cups bei? "e the air is exhausted, one ol the cups being exposed. Fig. ft is a sectional detail view, showing the action olE the glass on the cups when the :.ir is exhausted. Fig. 5 is a view similar to Fig. 3, but showing the table provided with supplementalsupporting abutments. Fixer. (i is a broken plan View, showin;` the said construction.
The rotatable ldass supporting table A is preferably made ot an upper wall 2 and a lower wall $5 providing an interior air cavity 4. rThe table made in a plurality of Sections and divided at the line 5,' the secA tions constitutingr units ol the complete table, connected as shown, and providing for continuous circulation ot the air throughout its entire interior, by means of the ccntral, connnon rotatable air conduit or hollow spindle 6. Said spindle may be connectedwith the interior of the table in any suitable manner, operating as a hollow' Inast which may act as the main steinof the table,
and which may be provided with anA actuating drum or pulley 7. Such drum is rigidly incorporated with the table or its central mast in any suitable manner, as shown, resting upon roller or ball bearings S, being driven by a pulley or cable engaging the peripheral groove 9, as will be readily understood.
10 represents an air exhausting device of any suitable construction having an operating steam pipe connection 11, an exhaust teri'ninal 12, and a suction conduit 13. Said conduit makes a tclescoping engagement with the lower end of the rotatable mast 6, as indicated at 14, being provided with suitable packingr or other customary or necessary attachments or parts, whereby con munieation may be established with the interior cavity -'lot the table at all times.
The upper wall 2 of the table, or of the several connected units comprising' it, is provided with a numerous series of attaching bushings 15 tapped into the shell 2 and having;r a central opening, preferably tapered, into which is inserted the hollow nipple 1G o'l. the resilient cup 17. preferably oi rubber, is so constructed as to bear upwardly underl'ieath the underside of the plate a, as shown in Figs. 2 and 3. and,
to be compressed by the weight of the plate and the exterior atmospheric pressure when Said cup, which is the air is exhausted from the interior oi" the table and through the hollow nipples 1G, as in Fig. 4.
Tn utilizing' the invention, the plates c, which are usually rmtane'ular, leave uncovered certain oi' the cups which are thus not utilized. llor the purpose oi closing' them against atmospheric circuhation, each is provided with a check valve ih. which may Il@ in the torni ot' a rubber or other ball. and which will tightly seat in the upper portion ot the nipple at the ba c ol' the cup. ell'ecing the desired closure, For such purpose, and to insure seating ol' the valve IH below the plane ol' the under side oll the glass. when depressed by air pressure, the valves are 'compress-rd, as indicated in Fig. 4, thereby bringilng all ol the several plates down to a common level, and wliereby the grinding, smoothing a'nd polishing operations of the runners may be readily aeeoniplished.
It' itlis desired to space the cups apart, or in any ease, to provide intervening supports` Jfor the glass plate, supporting abutnients of any suitable kind may be extended upwardly from the main surface et the table to receive `the glasf in its lo\\ered position, and assist in the sipporting af'iionV of the cups. Such abutmen may be of any suitable construetion, as shown in Figs. 5 and G, wherein transverse intersecting ribs 20 extend upwardly from the upper vfall 2 of the table and between adjacent cups, throughout the area of the table. These may be of any suitable construction or arrangement, and Will also assist in maintaining a uniform level of the glass.
The advantages of the invention Will be readily understood and appreciated by all those familiar with this class ol. apparatus. It obviates the necessity of the usual cen'ienting or other laborious and expensive methods in vogue for holding the glass plates to the table, admitting' ot their easy and quick removal or reversal upon admission oi. air to the interior. blut-.h admission may be effected by any suitable valve mechanism or by operation oi the pump member l0.
The number ot' the cups, their arrangement, shape or other features or details of construction may be variously changed or modified by the skilled mechanic, but all such are to be considered as Within the 'scope y of the following claims.
`What I claim is:
1. A rotatable glass grinding table having a hollow interior, means for exhausting the air therefrom, and a plurality of individual suction cups of resilient material located onn up-per supporting wall, thecombination with said wall efr; plurality of individuallyfinserted suction oups eaeh having an air eXn haust opening therethrough and provided with a removable cheek valve device, substantially as 'set forth.
4. In afrotatable glass supporting table oit the class described having an interior vacuum cavity and an upper supporting Wall provided with upwardly projecting supporting abutments; the combination With said upper wall of a'series of colnpressible resilient suetion eupslecated between said abutments, having air circulation openings therei through, andmdapled to be depressed to the Jupper level of said abutments substantially as set fortln! l'n testimony whereof I hereunto aiiix my signature in the presence of two Witnesses.
