KLASSE 35: Hebezeuge.CLASS 35: Hoists.
Die Hebevorrichtung ist in vorliegend gedachtem Falle in einem Gehäuse gelagert, dessen zwei Lagerbügel L L1 oben durch das schmiedeiserne Querstück P mit Anhängehaken P1 und zu beiden Seiten durch die Schraubenbolzen b fest mit einander verbunden sind. ^ In den Bügeln L L1 sind zwei Achsen A und B gelagert, wovon auf A die aus einem Stück gegossene Kettennufs N mit den zu beiden Seiten angeordneten Stiftenscheiben W und W1 aufgesteckt ist, während auf B die beiden mit spiralförmigen Curven versehenen Scheiben T T1 und das Handkettenrad H aufgekeilt sind. An die in den Scheiben W und W1 in genauen, gleichen Abständen befestigten Stahlbolzen s S1, wovon die der einen Scheibe gegen die andere Scheibe um einen bestimmten Betrag nach rechts verstellt sind, legen sich die Curven C1 C3 und C2 C4 der Curvenscheiben T T1 bei Drehung des Handkettenrades H abwechselnd an und versetzen durch ihre eigenartige, aus der Zeichnung ersichtliche Construction und durch das Entlanggleiten an s bezw. S1 die Stiftenscheiben und somit auch die Kettennufs in eine um A drehende gleichmäfsige Bewegung, so dafs eine dort eingelegte Kette mit anhängender Last gehoben bezw. gesenkt werden mufs. Für letzteren Fall sind zur sicheren Rückwärtsbewegung vier Gegencurven K1 K3 bezw. K2 K^ noch angeordnet.In the present case, the lifting device is mounted in a housing, the two bearing brackets LL 1 of which are firmly connected to each other at the top by the wrought iron crosspiece P with suspension hook P 1 and on both sides by the screw bolts b. ^ Two axles A and B are mounted in the brackets LL 1 , of which the chain hub N cast from one piece with the pin washers W and W 1 arranged on both sides is attached to A , while the two TT 1 disks with spiral curves are attached to B and the hand chain wheel H are keyed. Curves C 1, C 3 and C 2 C are placed on the steel bolts s S 1 , which are fastened in the disks W and W 1 at exactly the same intervals , of which the one disk is adjusted to the right by a certain amount in relation to the other disk 4 of the curved disks TT 1 alternately when the hand chain wheel H is rotated and move by their peculiar construction, which can be seen from the drawing, and by sliding along on s respectively. S 1 the pin washers and thus also the chain knobs in a uniform movement rotating around A , so that an inserted chain with an attached load is lifted or lifted. must be lowered. In the latter case, four counter curves K 1 K 3 respectively are for safe backward movement. K 2 K ^ still arranged.
