can slip out.

Patented in the German Empire on December 28, 1911.

The invention relates to a remotely operated tow hook, in which a hook is turned by turning a support holding it so that the hawser slips out can. The purpose of the new device is to minimize the resistance that has to be overcome when the support is folded down to make it small.

An embodiment of the invention is shown in the drawing. It shows:

Fig. Ι the tow hook in the position of use,

Fig. 2 in the released position and
Fig. 3 is an upward view of the hook.

The hook δ, into which the towing cable g is hooked, is held in the hook housing α by pegs d , which are mounted in horizontally extending slot holes so that when the cable is inserted, ie when towing, they are at the front end of the slot holes and therefore not are loaded, rather allow the hook b to move backwards when slipping. The hook b finds its support when it is towed and the hawser g is tensioned by means of two pins f in a forked hook c, A, which in turn rests with its back against fixed jaws i in the hook housing α so that the support point on these jaws in a straight line with the direction of pull of the hawser and the support point of the pin f in hooks c, k . As a result of this arrangement, the hook c, k is not subjected to rotation, and the cable is taken up entirely by the jaws i in the housing. In order to slip the tow rope, a rotation of the hook c, k must therefore be made, which is made possible by the fact that the jaws i are beveled at their upper end and thus do not prevent the hook ends h from whipping around. When the hook c, k is rotated, the pegs f of the hook b slip out of it, so that it is now around the lower pivot d, which, when the hook c, k is turned over, as a result of the backward movement of the hook b towards the rear end of the slot hole can also fold down and release the cable g. In order to hold the hook c, k in the rest position, ie when towing, and to be able to cause its rotation to slip, a support e is rotatably mounted in the front end of the housing α , which is pressed slightly backwards by a spring and against which an extension / of the hook C ₁ k supports. The lower end of the support e is designed so that when the latter is folded over , it presses the extension I of the hook c, k upwards in order to release the pin f of the hook b.

So that the hook I ₁ has a hold in the housing α when it is not being dragged, it is provided with pegs h which rest in mortises in the housing α with such clearance that they only come to rest after a small rotation of the hook c, k .

Claims (1)

The advantage of the new device is that there is no rotating force on the hooks c, k when towing, and that there is no friction between the extension I of the hooks c, k and the support e , which makes it difficult to fold the latter. In addition, the turning of the hook c, k is to be facilitated by the fact that his back is only supported against the jaws i . Pa τ ε ν τ - A ν s ρ κ υ cn: Tow hook with slipping device, in which a hook is rotated after a support holding it in the rest position has been turned over so that the cable can slip out, characterized in that this hook (c) into which the actual tow hook which can be folded over around a bolt (d) (b) is hooked, is mounted in such a way that its support point and the point of application of the train of the tow hook (b ) fall in the direction of the train of the tow rope (g) , that also the abutment for the hook (c) of two jaws (i ) is formed, and that the hook (b) is held with clearance by journals (d) mounted in the hook housing. 1 sheet of drawings.
