KÖZLEMÉNYEK - Mendele Ferenc–Németh B. Ferenc: A kiskunhalasi műemlék-szélmalom helyreállítása

betteten Zwercheisen und der Steinanhiebkran in der Höhe der Steinbank wurden gleichwohl ersetzt. Das Mahlgut gelangt über einer neuen Rutsche in das Erdgeschoß. Die Brückensäulen und Brückenbalken der Mehlbank, samt Scheibeneisen, Seitenbüchse und Handschrauben bedurften nur einer Reparatur. Zwischen den Brückensäulen stehen neue Mehlkisten. Im Verlauf der Wiederherstellung mußte man die zum Betrieb der Windmühle unentbehrlichen Werkzeuge (Haspel, Stemschneidmlttel, Aufgußschaffel, Haken, Ziehkette, usw.) ersetzen. Die aufgefrischten Holzzahnräder sichern ein Übersetzungsverhältnis 1 :8 zwischen Wiindmühlflügel und Mahlsteinen. Die maximalzulässige Drehzahl der Mühlsteine beträgt 140... 160 U/imin. Bei einer idealen Windgeschwindigkeit von 4 ... 5 m/s liefert die Windenergie eine Triebkraft von 14 ... 16 PS. Die wiederhergestellte Windmühle zu Kiskunhalas, die sich zum Mahlen von jährlich 2000 Zentner Getreide eignen würde, steht unter der Pflege und Betreuung des örtlichen Jänos Thorma Museums. F. MENDELE — B. F. NÉMETH RECONSTRUCTION OF THE HISTORIC BUILDING OF THE KISKUNHALAS WINDMILL The windmill at Kiskunhalas, reconstructed in 1964—66 was built as a so-called bottom-drive mill in the first half of the 19th century. At the turn of the century the building was raised by one level and transformed into a top-drive one with three stonepairs. The Sáfrik mill has four levels from this time. In 1930 electricity and a hammer grinder were installed in the mill, and thus till 1950 the grinder operates in calm from electricity. From the end of the thirties the mill is used only for grinding, though earlier a rolling screen has been built in. The wing board and energy transmission structure could foe used till 1954. (In 1943 J. Kőrössy took over the mill and operated it till 1950 after the reconstruction.) At the end of the fifties the boards were dismounted, the windows bricked up. In spite of these at the beginning of reconstruction part of the apparatus was missing. When reconstructing the historic building the mudwalled, outwardly brickcovered mill-house was restored. A new roofing was made of pine shingle. The timbered ceilings, scales between the levels, doors and windows were renovated. The four-blade wing board, wind shaft and wind wheel were made in the course of reconstruction, as well as the turning coach and wheel. On the super-high gear wheel bench the stone spindles were corrected, missing wooden cogs of the big-spindle and super-high gear wheel were replaced and a new sack elevator was made. Shafts of the stone spindles (forked axles) along with the three stonepairs (grinders) were available. The stonecrust, consisting of two semicylinders, the hopper-holding transoms, fop discard and shake hoppers were newly made. The upper (rotating) stoneembedded crossrails were also supplied. The stone lifting crane on the stone bench level was renovated, too. Grist is forwarded to the basement by a new chute. Bridge columns and bridge ties of the flour bench, along with the iron disc, side bush and hand-screws needed only mending. The flour-bins, standing on legs between the bridge columns, are new. In the course of restoration accessories for the operation of the windmill were also completed (winch, stonecutting tools, filling pail, grappling hook, drag chain, etc.). Renovated wooden cogwheels provide a transmission 1 : 8 between the wing board and grinding stones. The maximum allowable speed of the grinding stones amounts to 140 ... 160 r. p. m. Driving power supplied by the energy of wind — in case of an ideal wind rate of 4... 5 m/s — is 14.. .16 h. p. The reconstructed windmill of Kiskunhalas would be suitable for the grinding and milling of 2 000 q grain yearly. The reconstructed mill is under the care of the local János Thorma Museum.
