To all whom it mafz concern;
'B it known that I, Bnnsnnnn Fisonnn, engineer, a subject of the King of Saxony, and resident of Hohestrasse 79, Dresden, Kingdom of saxony Germnn Empire, hare invented new and useful Improvements in Grinding Apparatus, of which the followin' is a specification.
lhe present invention has for its ob3ect a rindin' apparatus jirovided with means 01"COIl311(3i1ng away y sucking action the dust generated during the grinding operation.
Aecordin .to the present invention, the grinding n fiaratns, the grinding wheel or ring of which is provided in a wfelllgnown manner with fan-blades for-"snaking n the dust en'eneted; is inolosed within a casing snrroundin' the said fan-blades end the grinding-w eel and such easing 1s te ded with oyerticelly arranged sticking s it end a perforated water in e or sprinkler, a dish or CUiXCOIlGCt i-Hg the l quid heed in the grind ing'jeoperatiqii and a free air-discharge for smoking awa end setthng the dust generated itndfor inahitaining. it purified ntm'o's; ph'ere withinthe-workroom.- The sucking s'iit is ,forined by a vertically adjustable work-table and the Ou er edge of the grindifig ififhei end the-water pipe or sprinkler, the liquid collecting dish sflpplyingthe my ten t the {vibe or sgrinkler mentioned end the lee air disehetge situated above said edllectinig dish or cup not together of in confu bitietioii with each ther in sneh 'e indnnet that the dost stroke in andeliflioiently isflturated with Witter is eompelled to nijtielly settle at thebottdm of the snrrofln in'g casing w erase the miter mi'xedwlth dust is fed into t e colleo ing dish or ,qiip andthe air A ilt is retiirned back into the m eqm edr AgrmdMg-ayfiamtim arranged eocortling to the present invention has, in o er'ison A tindihg-apperatus, t e mivantage that t 'e .fan mounted up to now sepaiateiy tit a suitable-distance from the nmchinesmd the-long pipe-system between the said {an 1nd the machine May be dispensed with and the power fofrnierly necesmy for driving the an-can be reduced to it Very eet'd egree.

9 is a perforated wateripo or sprinkler capable of being shut 0 end rojecting into the casing 6, below the fmn'blades 5. Said water-pipe or sprinkler is supplied with water by a pump, 10 or in anyother suitable manner. A pipe 9 connects the water-pipe or sprinkler 9 with the pump 10 which isdriven by a belt or bend-pulley 11, the belt or band of which runs around the pulley 12 of smaller diameter and fas- I tened to the shaft 13 of the pulleys 14, 15
- for driving the pulley 16 fastened. to the main shaft 3 of the apparatus. The rotary ing the rotary movement of this grindingwheel the fan-blades 5 suck in the air and simultaneously the dust generated during the grinding-operation. The dust generated is thrown into the hollow space or slit 17 also by means of the grinding-wheel 1 itself. In this manner, the water pipe or I sprinkler 9 moistens the dust-air sucked in so that the wet dust particles contained in it settle at the bottom of the casing 6 from which the water collected in the latter flows into the bed-plate 18 of the apparatus formed as a collecting cup, whereas the air sucked in enters into a pipe or passage 19 tangentially connected to the casing 6. In this manner, the said air may directly escape through the mouth 20 of the pipe or passage 19 into the work-room.
Any water and dust particles taken along by the air will fall down into a vessel 21 arranged below the mouth 20 of the air dischar e 19, said vessel being connected to the bed-plate 18. The wet dust-particles carried along will settle in this vessel by their gravity. The bedplate mentioned may be provided with ribs of difierent height, over which the collected water flows for being purified in such a manner that it will enter into the sucking-pipe 22 of the pump 10 in a nearly purified state and returned or supplied through the conduit or pipe 9* into the perforated water-pipe or sprinkler 9. By this means it will only be necessary to add fresh water once a day for replacing the water entering into the at-' mosphere in the shape of water-dust.
To keep the level of the sucking slit 17 and of the space within the casin 6 near the working-place 7 surrounded by t e lower,
part of the casing-wall, in correspondence with the wear and tear of the grinding surface 1, the working-table 23 which may be adjusted in height by an automatically stoppin worm-gear, is provided on its lower sur ace with a downwardly projecting edge or rim 24. This edge or rim will telescopically enter into the casing 6 in such a mannet that the air will be sucked 'n by the slit formed between the working-table 23 and the grinding-wheel 1.
The automatically stopping worm-gear mentioned consists of two worm-wheels 25, 26, the hubs of which are formed as nuts which are engaged by the screws of two long screw-bolts 29, 3O projecting in a downprojecting in an upward direction from act as nuts and cause an'upward or downward movementof the screw-bolts '29, 30
and together with said movement the ad justment of the work-table23.
A traverse or bar 37 arran ed above'the grinding-wheel 1 is fastened to thelateral posts 35, 36. A dressing-apparatus 38'is permanently mounted on said traverse or bar in such a manner that the'dust generated during the dressing of the grindingwheel 1 is compelled to directly enter. into the casing 6 acting together with the blades 5 as a fan.
I claim as my invention:
1. In a grinding-apparatus the combination with a rotating grinding-wheel, of means for sucking in the dust generated on said grinding-wheel, means for settling the dust generated, a work-table for feeding the work in hand to the inding-wheel, and means for vertically ad usting the table.
