SHIPS FENDER.

SPECIFICATION forming part of Letters Patent No. 448,074, dated March 10, 1891.

Application filed November 11, 1889. Serial No. 329,862. (No model.)

' useful Improvements in Ship-Fenders; and I do hereby declare the following to be a full, clear, and exact description of the invention,

- such as will enable others sk lled in the art to which it appertains to make and use the same.

This invention relates to ship-fenders.

The object of the invention is to obviate the usual disastrous effect of collisions upon the waters.

lVith this object in view the invention consists in one or more fenders arranged at the bow of a vessel, preferably attached to the cut-water or adjacent thereto and capable of vertical adjustment. Furthermore, the invention consists in one or more stationary fenders placed at the bow of a vessel and one or more vertically adjustable fenders designed to slide up and down upon the outwater and be retained atany desired elevation.

In the accompanying drawingsI have shown one embodiment of the invention.

In the drawings, Figure 1 is aside elevation of a portion of the bow of a vessel, showing my fenders arranged thereon. Fig. 2 is a front view of awessel with the fenders in the positions in which they are placed for use at the time of a collision, and Fig. 3 is a sectional View showing the preferred form of tender.

In the drawings, A represents the bow of a vessel, and (t represents the cut-water. Attached to the cut-water is a bar or rod of steel or iron arranged to leave a space between it and the cut-water, allowing free movement and suflicient play to the the rings or slides, by which the movable fenders are attached to the bar or rod.

B B 13 represent fenders of any suitable size, which are connected with the bar or rod by rings, which permit a free up-and-down movement. The upper fender B is arranged near the top of the cut-water, and is preferably stationary in use, though so attached to the rod as to permit ready detachment, if desired. The two fenders B and B are designed to slide upon the bar or rod a, allow ing them to be drawn up into the position shown in'Fig. 1 and to be dropped into position shown in Fig. 2.

The fenders are each provided with ropes or chains 7) and I), attached to each end of the fenders. These chains or ropes are each attached on deck to drums or the like, (not shown,) by the manipulation of whichthefenders maybe raised or lowered at will or drawn upon the deck when desired.

The tenders are preferably made of rubber, though any suitable material may be employed. To add to the effectiveness, they may be provided with an interior chamber,in which are arranged springs upon which the force of the blow of a collision would be expended.

It is well understood that it the Wedge-like bowof avesselis prevented from entering the side of a vessel or any other object struck the effect of collision is greatly mitigated, and by placing the strong elastic fenders between the bow of the vessel and the object struck the bow is prevented from entering and damage is averted.

In the ordinary use of fenders they are until needed raised out of the water, and this offers no obstruction to the passage of the vessel through the water, and there is no space taken up that would be occupied by anything else. The fenders are compactly carried on the bow and in heavy weather can be hauled on board.

Of course it will be understood that the bar or rod upon which the fenders are carried will not remain uninjured aftera collision; but if it is damaged or carried away this is of no importance, as its otfice will have been performed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the bow of a vessel havinga guide device, of one or more movable fcnders arranged upon the cut-water and capable of sliding up and down thereon, substantially as described.

2. The combination, with the bow of a vessel having a guide device, of one or more stationary and one or more movable fenders, the movable fenders being arranged to be moved up and down on the guide device, substanfenders attached to the rod, and chains or tiall y as described. ropes attached to the fenders and attached to 3. The combination, with the bow of a vcsa drum or the like on the deck, substantially sel, of a rod or bar attached thereto and one as described.

5 or more stationary and one or more vertioally- In testimony whereof Iaffix mysignatnre in [5 movable fenders attached to the rod or bar, presence of two Witnesses. substantially as described. THOMAS RAFTERY.

4. The combination, with the bow of a ves sel, of a vertical rod attached thereto, one or 10 more stationary and one or more movable 1 \Vitnesses:
