PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung bezieht sich auf ein Mefsrad mit Zählwerk für Längenmessungen in Gestalt einer Schubkarre, mittelst deren man Feld, Acker oder sonstige Flächen, auch solche schlüpfriger Natur, auf einfache und zuverlässige Weise schnell genau zu vermessen im Stande ist.The present invention relates to a meter wheel with counter for length measurements in the form of a wheelbarrow, by means of which one can use fields, fields or other areas, including such slippery nature, can be measured quickly and accurately in a simple and reliable way Stand is.
Das wesentlich Neue an dieser bekannten Vorrichtung besteht dabei in der Anwendung eines Rades, an dessen Kranze Spitzen in derartigem Abstande angeordnet sind, dafs an der Lage dieser Spitzen die kleinen Theilstrecken zu ersehen sind, die am Zifferblatt des Zählwerkes nicht unmittelbar angezeigt werden. Gleichzeitig bewirken die Spitzen, dafs die Mefskarre auch auf schlüpfrigem Boden sicher arbeitet.What is essentially new about this known device is its application of a wheel, on the rim of which tips are arranged at such a distance that on the In the position of these peaks, the small partial segments can be seen on the dial of the counter cannot be displayed immediately. At the same time, the tips cause the Mefskarre works safely even on slippery ground.
Der Erfindungsgegenstand ist in der beiliegenden Zeichnung perspectivisch dargestellt.The subject of the invention is shown in perspective in the accompanying drawing.
An den Tragstangen α ist drehbar das Rad b gelagert, dessen Durchmesser in der üblichen Weise derart gewählt ist, dafs sein Umfang ein bestimmtes Längentnafs, z. B. 1 oder 2 m, beträgt. Der Umfang des Rades ist dabei in kleinere Mafseinheiten der beireffenden Längeneinheit, z. B. in Decimeter, eingetheilt und jeder Theilpunkt am Radumfang b durch eine Spitze, Rippe c oder dergl. bezeichnet, welche der Angriffsstelle der Speichen des Rades entspricht. On the support rods α , the wheel b is rotatably mounted, the diameter of which is selected in the usual manner such that its circumference has a certain length, z. B. 1 or 2 m. The circumference of the wheel is divided into smaller units of the beireffenden length unit, e.g. B. in decimeters, and each subpoint on the wheel circumference b is designated by a point, rib c or the like, which corresponds to the point of application of the spokes of the wheel.
Die Achse e des Rades b steht nun an einer Seite mit einer Zählvorrichtung in Verbindung, welche die Zahl der Umdrehungen des Rades b anzeigt und eine beliebige Ausführung haben kann.The axis e of the wheel b is now connected on one side to a counting device which shows the number of revolutions of the wheel b and can be of any design.
Das Zählwerk kann entweder bei einer vollen Umdrehung des Rades b um einen Theilstrich weiterrücken oder aber nach einer bestimmten Anzahl von Umdrehungen, beispielsweise 10, 100 oder dergl., wobei jedesmal bei einer vollen Umdrehung ein Läutewerk ein entsprechendes Zeichen giebt. Unabhängig von diesem Zählwerk, welches volle Umdrehungen angiebt, gehen nun mittelst der Spitzen c die Theilstrecken der abgemessenen Fläche abzulesen, und zwar sowohl während des Messens selbst, als auch durch Nachzählen der mittelst der Spitzen zurückgelassenen Spuren im Erdboden, so dafs stets eine genaue Messung ermöglicht wird.The counter can either move forward by a division with a full revolution of wheel b or after a certain number of revolutions, for example 10, 100 or the like, with a bell ringing each time with a full revolution. Independently of this counter, which indicates full revolutions, the partial distances of the measured area can now be read off by means of the tips c , both during the measurement itself and by counting the traces left in the ground by the tips, so that an accurate measurement is always made is made possible.
