BENJAMIN ARNOLD, OF EAST GREENWIOH, RHODE ISLAND.

OIL-DISTRIBUTING BOMB OR CASE.

SPECIFICATION forming part of Letters Patent No. 376,503, dated January 1'7, 1888.

I Application filed June 16, 1887. Serial No. 241,495. (No model) To aZZ whom it may concern/.-

Be it known that I, BENJAMIN ARNOLD, of East Greenwich, in the county of Kent and State of Rhode Island, have invented certain new and useful Improvements in Oil-Distributing Bombs or Gases; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a receptacle to hold oil, in which it can easily be thrown out on the water from on board a vessel or other position, and to provide this oilreceptacle with means whereby the oil will be released from it when it falls into the water, and is intended to facilitate the distribution of oil on the surface of the water at a distance from the vessel or stand from which itis thrown, for the purpose of preventing the action of the wind on the surface of the water and rendering it calm.

Figure 1 shows an elevation of one of the receptacles with its oil-releasing devices. Fig. 2 is a representation of the oil-receptacle A of Fig. 1 by itself. Fig. 3 is a separate View of the spring B of Fig. 1. Fig. at shows a crosssection of the apparatus, taken through line a: :20, Fig. 1. receptacle with an openingon one side and a spring to hold the stopple in it; Fig. 6 is an elevation of another form of the oil-receptacle. Fig. 7 shows a crosssection of the form shown in Fig. 6, taken on line on. Fig. 8 represents the form of the spring in Fig. 6 separate from the receptacle. Fig. 9 is a representation of a spherical shaped oil receptacle in cross-section. Fig. 10 shows a spherical-shaped oil-receptacle with two openings, also in section. Fig. 11 shows a tubular case open at each end, (before the confining devices are attached.)

The form of the oil-receptacle shown in Figs. 1 "1d. 2 consists ofa case, A, made of glass or ot.. er suitable material,and shaped like a common vial with the bottom cutoff. (See Fig.2.) A spring of wire, B, is bent in the shape shown in Fig. 3,and made of such a size that the loop 0 will enter only a little way into the large open end of the case A when the arms of the spring are open, as in Fig. 3; but when the arms are Fig. 5 represents a form of the oilcompressed to a parallel position, as in Fig. 1, the loop 0 will also be compressed, so as to enter the case A up to the outer bends of the spring.

A cork, S, of the proper size to just enter'the large end of case A, is fitted inside the loop of the spring B by-grooving the sides of the cork slightly to receive the wires of the loop, so that when the spring B is inserted in the case A,by 6Q compressing the arms as aforesaid, the cork S will close that end.

The arms of the spring B, when compressed close to the sides of the case A,are confined in that position by means 'of a strip of paper, 0, or some other material readily softenedby the water. This strip 0 is wound around the arms of the spring B over the case A, and the end secured by gumming it down.

The end of the case A, with the cork S and 0 spring B, is then to be dipped into melted paraffine, glue, or some other suitable substance that will enter and fill up any crevicesthere may be between the case A, cork S, and spring B and insure a complete closing of that end. The case is then ready to receive the oil, which is poured in through the neck or small end and a cork, N, inserted. The article, which may be called an oil-distributing bomb, is then ready for use, and upon being thrown upon the water the confiningstrip O at once absorbs water and becomes softened, so that the force of the confining-spring B will break it and allow the arms of the spring to expand suddenly and spread forcibly the loop 0, which will break open the sides of the end of the case A and allow the contents to escape onto the surface of the water, so as to render it calm bypreventing the action of the wind thereon. In the form of case shown in Fig. 6 a different- 0 shaped spring is used, which is shown in Fig.

8. The case is made with projections a a on its side. The spring is compressed and its ends confined by means of the strip 0 of some absorbing substance, as was described in Fig. 1. 5 The loop is then inserted between the projections at a, the space between which it should about fill. The spring may then be held in place on the case by having a strip of paper pasted over it. WVhen the case is thrown on too the water, the strip 0 is softened, so as to release the spring B, which will by its forcible opening break the case open by spreading the projections a a apart, and so release the contents of the case.

In the forms of the cases shown in Figs. 5, 9, 10, and 11 the spring is not intended to rupture the case on being released by the moistening of the strip that confines it, but by its rebound to throw out the corks, which are made tapering, so as not to stick in the openings, and release the oil. The spherical-shaped cases shown in Figs. 9 and 10 are more espe' cially intended to be projected out on the wa ter by means of a ball-trap or small mortar, while'the oblong shapes before described are intended to be thrown by hand.

The cases in Figs. 9, 10, 11 are shown in section for clearness. Fig. 9 shows aball or bomb with two openings, and Fig. 10 one with only one opening. The dotted linesin both figures show the position of the springs and corks when released by the moistening of the strip that confines them. a

In the different shapes shown in the drawings the different parts the case, the absorbent strip, thecorks, and the springs-ware considered identical, and also their principle and mode of operation, and they have accordingly been lettered alike.

As before mentioned, the cases may be made of other material besides glass, especially in .the forms shown in Figs. 5, 9, 10, 11, which,

not being intended to be broken by the action of the spring, may be made of papier-mach, tin, or other sheet metal. Pieces of sheet metal with leather or rubber under them may be used to cover the openings instead of corks. The spherical-shaped cases may be made in two parts, with a spring inclosed to throw them apart when the confining-strip, around them is softened by the water.

Having thus described my improvements, what I claim as my invention is- 1. In combination with a case for holding oil to be distributed on the water, a spring, B,

placed on the outside of the case, and a strip, 0, of material pervious to water, for the purpose of confining the spring, all constructed and arranged so that when the strip is moistened it will break, release the spring, and allow the oil to flow out upon the water, substantially as and for the purpose set forth.

2. The case A, having an opening in it, in combination with a stopper, S, for closing said opening, spring B, for holding the stopper S, and the strip 0, of material pervious to water, to confine the spring while under strain, substantially as and for the purpose specified.
