FLOATING ANCHOR AND OILER.

SPECIFICATION forming part of Letters Patent No. 378,171, dated February 21, 1888.

Application filed October 13, 1887. Serial No. 252,2i6. (N0 model.)

To ail whom, it may concern.-

Be it known that I, llIICHAEL MCCARTHY, of Middletown, Connecticut, have invented anew and useful Nautical Apparatus, which I denominate a Floating Anchor and Oiler, of which the following description and claims constitute the specification, and which is illus trated by the accompanying sheet of drawings.

This invention consists of a flat bag, made of canvas or other porous material and provided with rigid edges, and adapted to hold oil and to be held in the water at some distance from the deck of a ship by means of a rope extending from the apparatus at substantially rightangles to the surface thereof to the vessel.

The function of the apparatus consists in holding thebow ofthe vessel towindward when outridinga storm, and consists, also, in casting oil upon the waters some distance to windward of the vessel to which it is attached.

Figure l of the drawings is a perspective view of the apparatus. Fig. 2 is a fragmentary front view of the left-hand upper portion of the same. Fig. 3 is a vertical section on the vertical dotted line of Fig. 2.

A is the frame of the apparatus, made,prefcrably, by uniting four iron pipes of equal length, and provided with right and left hand screw th reads, respectively, upon the opposite ends of each, with four hollow elbows, the interiors of which are furnished with corresponding screwthreads, and the exteriors of which are provided with eyes or staples, to which the ropes B are respectively attached. Those ropes are of equal length, and their outer ends are made fast to the ring C. The rope D extends from that ring to the deck of the ship when the apparatus is in the water, and the rope E extends from one corner of the apparatus to the deck of the ship for a supplementary purpose hereinafter mentioned.

The bag F is composed of two thicknesses of heavy canvas, and is preferably bound with the cord G, while the two thick nesses are fastened together by the grommets H, of which any suitable number may be used to accomplish the desirable object of holding the two thicknesses of the bag together atsundry points upon their surfaces. The grommets I are also fastened through the bag F, near its border, on all sides thereof, and the riveted rings J have their heads united through those grommets, while their outer parts encircle the tubes which cempose the four sides of the frame A. The bushing K, provided on its inner end with the tube L, and capable of being closed at its outer end by the screw-cap M, gives entrance for oil to the interior of the bag F. A supplementary bag,N,may be filled with air or oil and attached to the upper grommets and rings in substantially the same way that the bag F is held within the frame A.

\Vhen out of use, the frame may be taken apart by unscrewing its pipes from its elbows, and the bags may be emptied and folded up with the parts of the frame, so as to occupy a small space on shipboard.

WVhen the apparatus is to be used, the bag F is filled with linseed or other animal or.vegetable oil, and the bag N is filled with oil or other like liquid or inflated with air, and then the two bags and the frame are assembled in the relative position shown in Fig. 1.

The mode of operation is as follows: iVhen the vessel is hove to with its head to the wind to outride a storm, the frame and the bags attached thereto are cast overboard at or near the bow of the vessel. The rope D isretained on board, and the bagNiioats upon the top of the water, while the frame A and the bag F are submerged in such a position that the plane of the frame is at right angles to the direction of the rope D. As the wind drives the vessel to leeward, the rope D is made taut, and the apparatus, not being materially affected by the wind, is not driven with the vessel, but remains at whatever distance off the how the length of the ropeD will permit. While the apparatus remains in that position it powerfully resists the leeward motion of thevessel, and thus acts like an anchor in the water. Atthe same time oil exudes through the meshes and pores of the bag F and rises thence to the surface of the water, where it powerfully tends to allay the waves. In serving like an anchor, the apparatus operates to keep the vessel out of the trough of the sea, and in serving as a distributer of oil some distance off the bow of the vessel the apparatus operates to diminish the violence of the advancing waves before they reach the bow of the ship. when the apparatus is no longer needed overboard, the rope side of the frame A by means of IOO D is slackened and the rope E is pulled, and the apparatus is thus brought to a horizontal position upon the surface of the water, whence it is easily hauled on board.

The bag N maybe omitted and the position of the apparatus near the surface of the water be maintained by its own buoyancy. So, also, the bag B may be lashed to the frame with ropes, instead of being held thereon by rings, and the grommets which hold the two thicknesses of the bag F together may be omitted, though I prefer to use those grommets and those rings.

The size of the apparatus should be adapted to the size of the vessel to which it is to be attached, and I calculate that one having sixteen square feet of surface 011 each side is large enough for a vessel of a hundred tons, and that apparatus of correspondingly larger sizes will hold correspondingly larger vessels out of the trough of the sea.

I claim as my invention-- 1. A floating anchor and oiler consisting of aflat bag, made of canvas or other porous material and provided with rigid edges and adapted tolrold oil; and to be held-in thewatcr at some distance from the deck of a ship by means of a rope extending from the apparatus at substantially right angles to the surface thereof to the vessel, all substantially as described.

2. The combination of a rigid frame and a flat bag, made of canvas or its equivalent and adapted to hold oil, and removably fastened within the frame, so as to operate therewith and be detachable therefrom, all substantially MICHAEL MCCARTHY.
