FENDERFOR SHIPS.

SPECIFICATION forming part of Letters Patent No. 293,321, dated February 12, 1884.

Application filed September 26, 1883.

T aZZ whom it may concern:

Be it known that I, J OHANN Hemmer: GRELL, Sen., a subject of the Emperor of Germany, and aresident of Hamburg, in the German Empire, have invented certain new and useful Improvementsin Means for Preventing or Lessening Damage to Ships from Collisions, of which the following is a specification.

The object of my invention is to prevent or lessen the damage arising to vessels from collisions by means of a simple and inexpensive attachment to the hulls of the same; and the invention consists of two or more ropes ofwire,

hemp, or other suitable material, that are stretched tightly in longitudinal direction around the hull and across the bow and stern, said ropes being retained by means of angleirons, between which the rope is confined, and by straps passing transversely across the ropes. To the bow of the vessel is applied in a similar manner a vertical rope, that acts as a fender to lessen the force of the shock.

In the accompanying drawings, Figure 1 represents a side elevation of a steamship provided with my improvement. Fig. 2 is a bottom view of the same. Figs. 3 and 4 are end views, showing,respectively, the bow and stern.

Fig. 5 is a vertical transverse section of a part of the hull drawn on a larger scale; andFig. 6 is a detail vertical transverse section, showing the manner of fastening the rope to the hull.

Similar letters of reference indicate corresponding parts.

A represents the hull of a steamship or other vessel; and a is a rope of wire, hemp, or other suitable material, of which one or more are stretched tightly in longitudinal direction above the water-line around the hull of the vessel, the ends of the rope or ropes a being connected together. Each rope is securely retained in position on the hull by means of' angle-irons b b, which are fastened tothe hull parallel to each other, of a depth of about half the diameter of the rope a, and of a width from (No model.)

The rope a is retained between the an gle-irons b b by means of cords, straps, or wires 0, that are drawn tightly transversely across the rope a from one angleiron to the other and fasten ed thereto in order to retain'the rope a in the required position, as shown clearly in Fig. 6.

According to the size of the vessel, one, two,

' or more horizontal ropes may be used to protect the hull and distribute the effect of the collision overthe whole surface of the hull,

each other equal to the diameter of the rope. 5

thus increasing the power of resistance of the nally around the sides and ends of the same,

parallel angle-irons, which are attached to the hull at each side of the rope or ropes, and transverse straps that extend across the ropes and serve to retain them between the angleirons, substantially as and for the purpose set forth.

2. The combination, with the hull of a vessel, having one 'or more pairs of parallel angleirons extending longitudinally around thehull, of ropes retained by said angle-irons and transverse straps, and of avertical fendervrope applied to angle-irons of the stem-post of the bow, substantially as set forth.

In testimony that I claim the foregoing as my invention Ihave signed my name, in presence of two witnesses, this 31st dayof August,

JOHANN HEINRICH GRELL, SEN. Witnesses:

ALEXANDER SrEoHT, EMIL HAASE.
