SPECIFICATION forming part of Letters Patent No. 305,250, dated September 16, 1884-.

Y Application filed May 8, 1884. (No model.)

To all whom it may concern.-

Be it known that I, ELDRIDGE A. THOMP- sON, of Silver City, county of Owyhee, and Territory of Idaho, haveinvented an Improvement in J oint-Protector and Igniter for Fuses; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful protector for the joint of a fuse, whether said joint be made by the union of two piecesof fuse or the union of the fuse with the cap, said protector being also applicable as an jgniter of the fuse.

My invention consists in a peculiarly-prepared water-proof and inflammable cloth, wound around the fuse at a j oint, or tied around the end of thefuse, asI shall hereinafter fully describe. i

The object of my invention is to keep the joint dry, especially the joint made by the union of the fuse with the cap, and also to I provide a ready means for igniting the fuse.

Referring to the accompanying drawing, the figure is a perspective view of a fuse and cap, showing the application of myjoin't protector andigniter.

A is a piece of fuse, and B the cap 011 one end. 0 is the protector wound around the cap and fuse, and covering the joint made by their union. D is a piece of the same material as G, tied around the fuse near its end, and having its free ends brought together ready for ignition. These ends may be made of any suitable length to regulate the period of their combustion.

The protector and igniter consists of a piece of cloth prepared in the following manner: rosin, mutton-tallow, and beeswax, in the proportions, approximately, of three pounds of .40 rosin, one pound of mutton -tallow, and one pound of beeswax, are taken and melted together. Into this melted mixture the cloth is dipped until it takes up sufficient to fill its pores and cover its surface with a thin layer of the material. WVhen the cloth dries, it is yet flexible enough to be handled in winding and tying, and is both water proof and inflammable. It is of prime importance to renderthe joint between the cap and fuse waterproof. When the hole is tamped with water, it is absolutely necessary to effect this result to prevent missing the hole, as the failure of the blast is styled. In any case, where dampness surrounds the fuse, it is essential to protect the joint. By wrapping my cloth around it, this is efiectually accomplished. It keeps the joint dry by reason of its imperviousness to water, and it does not hinder combustion in the least. By reason of its inflammable nature, it can be used, as shown by D, for igniting the fuse, a use to which it is adapted with better and cheaper results than the ordinary candlesnuff.

. V I am aware that the joint between the fuse and cap has been heretofore made water-proof to a certain extent by the use of soap, grease, tar, or clay applied to it, and I have heard of a waxed rope being used for this purpose; but I am not aware that a piece of cloth prepared as I describe, has ever been used, and I claim that it is more readily applied and more effective in its results than those materials I have mentioned.

' Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In combination with a fuse and a cap on its end, as described, forming a joint at its union with the fuse, the water-proof protector G, wound around the cap and fuse, and covering the joint, said protector consisting of a piece of cloth prepared by dipping it into a melted mixture of rosin, mutton -tallow, and bees wax, substantially as and for the purpose here in described. a

In witness whereof I have hereunto set my hand.

ELDRIDGE A. THOMPSON.
