CONTINUOUS GLASS-POLISHING MEANS.
Application filed September 3, 1926. Serial No. 133,338.
This invention relates to apparatus parand adapted to guide the successive backticularly intended for grinding or polishing ward and forward movements across the plate glass in a continuous manner. tables of respective sets of glass surfacing An object of the invention is the provision units 5, which for convenience may hereinof a simple, efficient and practical machine after he referred to as polishing units.

Each guide 4 continuously at a slow speed under the hastwo runs, preferably in parallel relation, polishing means. across the table runway transversely thereof A further object of-the invention is the and the adjacent ends of the runs are conprovision of means for automatically, at et-t d by o ped portions of the guides dispredetermined intervals, cleaning or reposed without the table runway at opposite conditioning the felt covered working sursides thereof. The guides 4; are supported faces of the polishing members so they will at each side of the table runway by a respecc ti t ff ti l p li h th gl d tive set of standards '4' arranged alongside of will not scratch or otherwise injure the same e ables in Close relation thereto, and are also supported at the-looped ends thereof in by reason of the accumulation of the polishoutwardly spaced relation to the standards 7 ing or abradin'g material thereon.
Further objects and advantages of the invention will be apparent from the following detailed description thereof.
While the invention in its broader aspect is capableeof embodiment in numerous. forms, a preferred embodiment thereof is by respective sets of standards 8.
Each polishing unit 5 has a carriage or cross-head member 9 that is mounted in and guided for movements by the respective guide 4, and a vertical shaft 10 is journaled in each carriage. A rotary head 11 is carillustrated in the accompanying drawings, in Pied y Each ft 10 at its lower end and a hi h, plurality of runners or polishing blocks 12 Figure 1 is a top plan view of an appa- (in the present instance four in number) are ratus embodying the invention with parts cfirlled y ea h ad 11 for turning moveb k Fi 2 i a crogg-5ecti0n on merits therewith and for rotary movements th li 2 2 i Fi 1, Fi ,3 i a f relative thereto, as well understood in the mentary side elevation of the machine with T b cks 12 usually have their work parts removed. Fig. 4 is a section on the line surfaces Y f w th felt and arcadapt- 4- l in Fig. 1, and Fig. 5 is an enlarged ed to have polishing coaetion with the surfragnientary detail of one of the polishing facfioi h 11155 I as they move across the units and of portions of the associated drive Samed g idin mean Each pol shing unit 5 has an upstanding Referring to the drawings, 1 designates 13 SWWehd 0n the upper end of its h l t h i; glass t h f d carriagc 9 for free horizontal turning move-- polished, which is mounted on one or more f thereto, and h PD 0nd poiishing bl 2 f truck form Th the arm is connected to a drive chain 14 so tables are preferably arranged in train or that the assoc ated unit is caused to move tandem form in end abutting relation to pro- With the iis Connection of the vide a prolonged substantially unbroken top Several units with the chain also maintains surface length ise of th t i d th the un ts in proper spaced relation, the spactm'vel over id il 3 ing being such that a plurality of successive The tables 2 pass under one or more endunits are preferably in polishing coaction at less guides 4 arranged in spaced relation the same time with the glass being surfaced. lengthwise of the movement of the tables The chain 14 is disposed over the associated aworm wheel 18 in mesh with a drivework- 19 on a drive shaft 20 mounted in bearings 21 lengthwise of the frame and at one side of the table runway. The speed of movement of the chain 14 is preferably such that the polishing units will have a slow moveeach unit of a set.
ment across the glass being polished.
The rotary heads 11 of the polishing units are rotated at the desired speed by the engagementof a drive chain 22 with a sprocket wheel 23 on the upper end of the shaft 10 of The chain 22, in the present instance, is disposed below the plane of the chain 14 and within the path of movement thereof in substantial parallelism therewith, being guided at the corners of its movement by idler rolls 24 loosely mounted on the shafts 16 so that such rolls and the sprocket wheels 15 may have movements according to the speed of movements of the respective chains 14 and 22. The chain 22 at one side of the table runway is looped inwardly around a drive sprocket wheel 25 that is mounted on a shaft 26 intermediate the pair of guide rolls 24 at that end of the guide. The shaft 26 is journaled in the associated bracket 17 and carries a beveled pinion 27 at its upper end in mesh with a companion pinion 28 on the drive shaft 20. A rotary movement is imparted to the polishing heads of the severa units throughout the entire course of their travel in the guide 4, except at the points where the chain 22 is looped inwardly around the drive sprocket 25.
A set of rollers 30 is disposed at each side of the table runway to support the units 5 while traveling the looped portions of the guide 4 or while passing from one cross run to the other of a guide. The rollers 30 of each set are journaled at their inner and outer ends in rails 31 and 32, respectively, the rail 31 being carried by the standards 7 and the rail 32 by the standards 8. and both blocksras they pass thereover.
extending in parallel relation lengthwise of the table runway.
In order to clean or re-condition the felt covered working surfaces of the polishing blocks 12 at a predeterminedpoint in each cycle of movement of the units, a scraper blade 33 is disposed between two of the rollers 30 'of one set substantially centrally of 'the associated end loop of the guide 4 and is elevated sufficiently to havescraping coaction with the working faces of the The scraper 33 is preferably disposed below the end of the guide at which the unitsprocket wheels 23 remain in engagement with the chain 22 so that the polishing heads of the units will be rotated as they pass over thc'scraper.
The scraper 33 is mounted at its ends in vertical guides 34 secured to the undersides of the associated rails 31 and 32 and is verticallyv adjusted in the guides by screws 35 (see Fig. 3). v
In theuse of the machine, the glass 1 to be polished or ground, which may be in continuous sheet form or in sectional form,
is mounted on or supported by the tables 2 and fed lengthwise of the machine and under the polishing units by the movement of the tables. Any number of sets of polishing units may be employed tosuit the work to be performed and each set has its polishing units moving continuously and in successive order first in one direction and then another across the glass, this being accomplished by the driving action of the chain 14. At the same time the polishing members of the units are given the desired rotary movements by the driving connection of the chain 22 therewith. The working surfaces of. the polishing units are cleaned and re-conditioned after leaving the glass at one side thereof by coaction with a scraper blade 33 which is vertically adjustable to compensate for wear and to vary the pressure intended to be exerted thereby a ainst the under-surfaces of the polishing b ocks.
I wish it understood that the references herein to plate glass applies to and includes all kinds of sheet glass which is adapted to be ground or polished and is not restricted to that kind of glass which is commonly referred to in the trade as plate glass; also that the term polishing as used herein is intended to include any abrasive action applied to the glass, whether the same be for grinding or for polishing the same, and that while the machi'ne described herein is intended primarily for polishing, strictly speaking, glass plates or sheets, it may also be used for the'grinding of the surfaces of such sheets.
