NITED STATES PATENT OFFICE.

CHARLES PERLEY, OF NEW' YORK, N. Y.

HAWSE-PIPE.

Specification of Letters Patent No. 80,7 5 5, dated November 27, 1860.

To all whom it 'may concern:

Be it known that I, CHARLES PERLEY, of the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Hawser- Pipes for Ships and Vessels; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, wherein- Figure l is a plan of said improvement, and Fig. 2 is a vertical section of' the same.

Similar marks of reference denote the same parts.

The hawser pipes now usually passing out at the bows of steamers and other vessels are a source of annoyance to the crew because in running through heavy seas a jet of water will often strike through the hawser pipe for a considerable distance within the vessel; hence the forecastle of the ship is usually only tit for storage of old materials such as rope, &c., and even when a heavy sea is not running the wind and spray render this portion of the ship almost useless. Various attempts have been made to close these hawser pipes; cylinders of wood have been inserted into them, but in a heavy sea these are knocked out to the risk of personal injury to those near at hand, or else the force of water penetrates between the pipe and the wood, and wets the interior of the space, and if the wood swellsunder the action of the water it becomes difficult to remove the same as promptly as often required. With a view to obviate these difficulties I introduced several years since a hanging shutter at the outer end of the port drawn in by a rope, but if said shutter got loose in a storm the waves were apt to break the hinges and difficulty existed in securing the same again in lace.

The nature of my said invention consists of a movable cap or shutter applied to the inner end of the hawser pipe, and clamped thereto so as to be watertight, whereby the forecastle of a ship is rendered as dry and comfortable as any other portion. The cap is easily removed when necessary and being at the inner end of the hawser pipe is so far removed from the direct action of the waves as not to be liable to injury, for the force of the wave is partially broken by the air confined in the hawser pipe in its inclined position.

In the drawing a, represents a portion of a vessels bow or other portion at which the hawser pipe o, is applied. This hawser pipe is to be of any usual size or construction. I prefer that the extension o, of the hawser pipe be applied to the inner end and secured bythe flange l, because this part c, serves as a guide to the chain and a protection to the hawser from injury, although the inner end of the hawser pipe itself may be adapted to receive my cap or shutter d, which I have represented as fianged around its edge setting into a grooveQ, against an india rubber ring. In order to secure this cap or shutter firmly in place I have represented the bent arm c, attached to the hawser pipe by the eye 3, and provided with the clamping screw f to press the edge of the cap (l, firmly against the rubber or elastic packing in the groove 2. The convenience, reliability, cheapness, durability and efficiency of my cap or shutter to the hawser pipes will be fully apparent.

Vhat I claim and desire to secure by Letters Patent is i The movable cap or shutter applied to the inner end of the hawser pipe and clamped thereto, for the purposes and as specified.

In witness whereof I have hereunto set my signature this third day of November, 1860.

CHARLES PERLE Y.
