HEUZE GLAss POLI-SHING APPARATYUS Filed A ril 2, 1928 2 Sheets-Sheet 2 Patented Feb. 11, 1930 PATENT OFFICE CHARLES nnuzn, or AUVELAIS, BELGIUM GLASS-POLISHING APPARATUS This inventionrelates to continuous glass polishing apparatus oft-he type in which the runners travel as well as the glass, andhas for its object means whereby the different media required for polishing during different stages of the travel of each runner, are supplied tothe runner.

In polishing glass by the above-mentioned type of apparatus, each runner has to. be supplied with a medium which is different for different stages off travel of the runner. customarily, rouge and water are employed asimedia, a mixture of rouge and: water in varying proportions being. supplied at" some i stages, whilewater alone, in varying quantity, is supplied at other stages. The invention is applicable to the supply of any me"- dia suitable for polishing, and the term medium or media is hereinused to mean any .2 substance or substances suppliedto the polishing runners.

A receptacle is attached to each runner, which passes successively under the outlets of a plurality of fixed,tanksand-receives polishing mediunrtherefrom during the travel of the runner and distributes the polishing medium toits felts. 1 Inthe accompanyingdrawings-P Figure 1 isa side view of aportion of the polishing apparatus, largely diagrammatic;

Figure 2 isan'end view of one of the pole ishing runners, partly broken away; 1 V Figures 3 and 4c are views similar to Figure lshowing alternative arrangements; and

Figure 5 is a sectional elevation of one constructional form of valve for. thedistribw tion of the polishing medium.

Referring to Figure 2, the glass rests on the tables 21, which slide on fixed guides 22 and are caused to travel by the rack 23 and pinions 24:.

The polishing runner shown in Figure 2 is of the type in which a frame 1 extends across the apparatus and carries a pluralityof runner spindles 2, of which one only is shown. The runner frame 1 slides on fixed guides 25 and is caused to travel by chains 26 supported on rollers 27 and engaging projections 28 on the runner frame. The rotating runner spindie 2isxshown carrying two runner heads 3 Application filed April 2, 1928, Serial No. 266,731, and in Great Britain May 24, 1927. V

with their felt pads 4. Since this runner spindle is of ordinary type,- no further description isdeemed tobe necessary. Refer ring to Figure 1, the runner frames 1 are shown travelling in close proximity, the direction of travel being indicated by the arrow. A plurality of fixed tanks 5 contain the different polishing media adapted to the diflerent stages of the polishing operation, and each has its outlet pipe 6 which may be controlled by a valve and is kept permanently open during the operation of the apparatus.

Attached to each runner frame 1 is a receptacle consisting of a double inclined trough 7, the left-hand end of the trough of one runner as viewed in F igure l, overlapping the right-hand end of the trough of the following runner, so that the series of troughs 7 form a continuous trough system.

Referring to Figure 2, theoutlet pipebiof one of the tanks 5 (which latterare notrepresented in the said figure) is shown immediately above the trough 7 here seen in end view, and attached to the runner frame lby abracket 8. Immediately below the lowest point of the trough 7 which is there provided with an aperture, is a funnel 9 adaptedto lead the medium supplied tothe trough, into a distributing valve 10, attached-tothe-runner frame by a bracket 11. Fromthe distributing valve 10, a pipe runs towards each of the runner spindles on the runner frame. in the drawing three pipes are shown, one 12 running towards the runner spindle 2 shown,

while the other two, 13 andli l, run towards similar spindles not shown. The distributing valve 10 is operated by a pulley 15,.w-hich is driven by a belt by any convenient means. The distributing valve 10 may be of. any convenient type adapted to give passage to the medium contained in the body of the valve, to each of the pipes, .12,- 13, 14 in turn.

A convenient form of valve is shown in Figure 5 in which a hollow spindle 29 rotated by the pulley wheel 15, leads polishing medium from the funnel 9 to the'interior of thevalve 10. The bottom of the valvelias holes 30 adapted to lead the polishing mee dium to the pipes 12, 18, 14 (Figure 2). Attached to the spindle 29is a plate 31.which rests on the bottom of the valve and has a single hole 32. As the plate 31 turns, the polishing medium in the valve passes through the hole 32 to the holes 30 in turn.

Each pipe, as 12, delivers the medium into a circular trough 16 attached to, and rotating with, the respective runner spindle 2 and from this trough, pipes 17 deliver the medium to the glass.

A distributing valve, such as 10, is conveniently employed when there is a plurality of runner spindles on each runner frame, but when said frame has only a single runner spindle, it is unnecessary, and the pipe 12 can pass directly from the aperture of the trough 7 to the trough 16. The distributing valve can also be dispensed with in the case of two or three runner spindles, the delivery pipes 12 etc., being all connected to a common funnel such as 9, but in this case accuracy in the distribution is not so well ensured.

By referring to Figure 1, it will be seen that during part of the travel of each runner, its trough 7 is not receiving a supply of medium. During this part of the travel, a continuation of the supply of medium to the glass may, if desired, be secured by suitable design of the aperture in the distributing valve 10 or of the trough or pipe outlets.

The supply of medium may, however, be made continuous from the tanks 5 to the glass, by suitablyrelating the length of each trough 7 to the distance between the tanks, as shown for example in Figure 3, where the runner frames 1 are shown spaced apart, and the length of each trough is equal to the distance between adjacent tanks.

Alternatively, the trough 7 may be made short. but capable of containing sufficient medium to maintain an eflicient supply during the travel of a runner from one tank to thernext, as in Figure 4. In this case the outlet of each tank 5 is provided with a valve 18 which, as shown at the left-hand end of Figure 4, is opened by a bar 19 attached to each of the troughs 7. When there is no trough undera tank, as is the condition represented at the right-hand end of Figure 4, the valve 18 of said tank is kept closed, by a weight or spring (not shown).

The devices shown and described for the automatic supply of polishing medium are convenient for the type of polishing runner illustrated, but these are to be regarded merely as convenient examples and are susceptible of various modifications for this or for different runners and apparatus without departing from the invention; for example, the pipes 6 instead of being directly connected with the tanks as shown, may be supplied with media from the tanks under pressure.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. In continuous glass polishing apparatus in which both the glass and the polishing runners travel, the combination with a plurality of runner frames of a plurality of fixed tanks adapted to contain polishing media, a trough attached to each runner frame adapted to receive the media from the tanks during its travel and long enough to receive polishing medium for a considerable part of the time of travel of the runner frame from one tank to the next, and means conducting the media from each receptacle to the polishing pads of the runner frame.
