Specification forming part of Letters Patent No. dated August 15 1865.
To all whom it may concern..
Be it known that I HENRI' iIOLDEN of the city county and State of New York have in-vented a new and Improved Torpedo; and I do hereby. declare that the following is a full clear and exact description thereof which will enable those skilled in the art to make and use the same reference being had to the accompanyingdrawings. forming part ofth is specification in which
Figure .1 represents a plan of this invention when unfolded and ready to be exploded. Fig. 2 is a transverse Section of the same.
Similar letters'of reference indicate corresponding parts.
This invention consists in a torpedo made of a plain sheet of paper or other absorbent material which is wholly or partially saturated with a solution of fulminate of silver or ofinercary iu such a manner that after dr ing the fibers or pores of the paper or other absorbent material are filled with fulminate and a slight blow or pressure with a hard substance causes the same to explode with considerable noise.
A represeil is a sheet o f paper-thick soft blotting-paper being used by preferencewhich I cut in the shape cf a polygon or circle so that the k acne can be readily folded in a small compass for packing and sending. I do not wish to confine myself; however to any particularshape of the sheet of paper. Neither do Ire-strict myself to the use of a particular kind of material. The sheet immerse in a hydrated solution of fulminate of silver which I use iii preference to fulminate of mercury and after it has been thoroughly saturated therewith I hang it up or lay it on a flat board for drying; or instead of immersing the whole sheetronly a portion of the same may be saturated by folding it up and pouring a quantity of the solution into it or in aityothersuitable man tier. After the saturated sheet has been dried the torpedo is ready. It explodes when struck with a small pebbleor other hard substance with great noise without the least danger to surrounding objects and the manufacture of my torpedoes can be effected without danger of an explosion since the fulminate is employed in solution and consequently in such a state that a spontaneous explosion is impossible.
I claim as new and desire to secure by Letters Patent
A torpedo made of a silent of absorbent material saturated wholly or partially with a solution of fulminateof silver or of mercury substantiallyas and for the purpose set forth.
