HAWSE-PIPE.

Specficaton of Letters Patent No. 27,482, dated March 13, 1860.

To all whom it may concem:

Be it known that I, T. J. SOUTHARD, of Richmond, in the County of Sagadahoc and State of Maine, have invented a new and Improved Ship s Hawse-Pipe; and I do hereby declare that the following is a tull, clear, and exact description thereof, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure 1 represents a perspective view of my improved hawse pipe, with a chain cable in red lines, passing through the same. Fig. 2 is a longitudinal section taken through the same, showing the roller recessed into the mouth of the pipe. t

Similar letters of reference indicate corresponding parts in both figures.

This invention is a novel improvement in hawse pipes through which the cables pass when the ship lies at anchor, these pipes are made of met-al and Situated under the ships head, and are employed to prevent the chains from rubbing or chafing the hull by the motion of the vessel or in casting or weighing anchor.

The object of my invention is to remedy a very serious evil attending the casting and weighing of anchors, or when the ship is riding at anchor, particularly when she is riding a heavy sea, arising from the rubbing and chating of the chain upon the hawse pipe.

Sometimes in casting anchor the cable will snap short on account of the frict-ion upon it .in the hawse hole, then again there will be burning in the hawse caused by the great stran the cable sustains during a heavy sea, and frequently it is necessary to fresh the hawse when there is reason to suspect the cable may be fretted in the hawse holes.

The constant casting and weighing of the anchors soon wears out the hawse pipe through which the chain passes, and to obviate this evil I have formed the mouth, C, of the hawse pipe, A, as shown in the drawings so that a roller, B, may be introduced at that point of the mouth where the greatest strain is felt, and the cable most likely to chafe. This roller is slightly grooved and is recessed in the lower lip of the mouth so that it will be turned by the cable in passing through the hawse hole, and a great amount of 'friction will be removed from the chain by the roller, and the cable may be paid out very rapidly with less danger of burning in the hawse, snapping the chain, or fretting the hawse pipe; the wearing of the chain occasioned by the movement of the vessel while laying at anchor will also be prevented. The roller or pulley, B, is secured in its place between the jaws of the pipe by a rod, a, as shown in the sectional drawing, Fig 2, and is allowed to rotate freely upon this rod. The pipes are made of various sizes according to the size of able used; the width of the roller, B, may be equal to the diameter of the hawse hole, or it may be much wider if necessary with its surface concave or grooved, as exhibited by the drawings.

It will be obvious, from the above description, that the employnent of the friction roller will materially assist the weighing of the anchor; and that much less power will be required to weigh the anchor than where the friction of the cable, in the mouth, of the hawse is to be overcome.

I claim* A hawse pipe extending into or through the side of the vessel, and provided on the outside end with a flanged head and checks, containing a roller substantially as described for the purposes set forth.

T. J. SOUTHARD.
