PATENTAMT.PATENT OFFICE.
Gegenstand des Patentes ist ein schmiedeisernes Bruststück für Windmühlenflügel. Die bekannten Bruststücke haben alle, abgesehen von ungeschickter und unschöner Konstruktion, mehr oder minder den Fehler, daß bei ihnen die Befestigung der Holzrute umständlich oder schwierig ist und daß die Holzrute an der Befestigungsstelle dem Verrotten ausgesetzt ist. Bei vorliegender Konstruktion' ist die denkbarThe subject of the patent is a wrought iron chest piece for windmill blades. the well-known chest pieces all have, apart from the clumsy and unsightly construction, more or less the mistake that with them the attachment of the wooden rod awkward or is difficult and that the wooden rod is exposed to rotting at the point of attachment. In the case of the present construction, that is conceivable
ίο beste Befestigung der Rute möglich und ein Verrotten derselben ausgeschlossen. Das Brust-ίο best attachment of the rod possible and one Rotting of the same excluded. The breast
. stück ist ein Träger in Fischbauchform, dessen Vordergurt (gegen den Wind gerichtet) aus zwei Winkeleisen W besteht, die nur in der Mitte durch das Blech C und bei D miteinander verbunden sind. Der Hintergurt H besteht entweder aus zwei Winkeleisen oder einem U-Eisen. Die Befestigung der Rute R auf dem Bruststück geschieht mittels sogegenannter Schraubenbänder 5, die die Rute und die Winkeleisen W umklammern und mittels Bolzen, die durch Rute und Winkeleisen hindurchgehen. Um die Reibung zwischen Rute und Bruststück zu vergrößern, werden die Winkeleisen W dort, wo die Schraubenbänder und Bolzen sitzen, mit eisernen Erhöhungen versehen, die sich beim Anziehen in das Holz der Rute eindrücken. Die Konstruktion besitzt die Eigenart, daß durch das Fehlen eines Verbandes im Vordergurt zwischen den Winkeleisen W eine Elastizität vorhanden ist. Der Verband wird durch die Rute selbst hergestellt. Beim Nachziehen der Schraubenbänder S, das wegen des Eintrocknens der Rute von Zeit zu Zeit erforderlich ist, werden die Winkeleisen W elastisch nachgeben, wodurch ein festes Umklammern beider Teile stets gewährleistet ist. Ferner liegt bei Verwendung von Winkeleisen ein Teil der Holzrute an der Auflagerseite frei und kann von der Luft bestrichen werden, wodurch ein Verrotten vermieden wird.. piece is a fish-belly-shaped beam, the front strap of which (directed against the wind) consists of two angle irons W , which are only connected in the middle by sheet metal C and at D. The rear chord H consists either of two angle irons or one U-iron. The attachment of the rod R to the chest piece is done by means of so-called screw straps 5, which clasp the rod and the angle iron W and by means of bolts that go through the rod and angle iron. In order to increase the friction between the rod and the chest piece, the angle irons W are provided with iron elevations where the screw straps and bolts are located, which press into the wood of the rod when they are tightened. The construction has the peculiarity that there is elasticity between the angle irons W due to the lack of a bandage in the front chord. The bandage is made by the rod itself. When tightening the screw straps S, which is necessary from time to time because the rod dries up, the angle irons W will yield elastically, whereby a firm grip on both parts is always guaranteed. Furthermore, when using angle irons, part of the wooden rod is exposed on the support side and can be brushed by the air, which prevents it from rotting.
