$PECIFICATION forming part of Letters Patent No. 309,095, dated December 9, 1884.

(No model.)

To all whom it may concern:

Be it known that I, GEORGE S. REEsE, a citizen of the United States, residing at Plymouth, in the county of Luzerne and State of Pennsylvania, have invented certaininew and useful Improvements in Squibs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters or figures of reference marked thereon, which forms a part of this specification.

The drawing is a representation of this invention.

This invention has relation to squibs for the use of miners and others; and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claims.

This squib is made of paper or any other suitable material, usually in one piece to form the powder-case a and the double match 11 b at the end of the powder'case and continuous therefrom. At the junction of the match portion with the case a the squib is flattened or pressed and sewed with thread at this point in such a manner that the thread penetrates and at the same time envelops the squib and guards the powder, preventing it from escaping through this end of the case or tube. This thread is designed to perform another important work, as a medium between the slow-burning match and the powder in the case or body of the squib. For this purpose before the thread is used upon the squib it is immersed in a strong solution of inflammable matte'r,thiss0lutionbeing very much stronger-for instance, fifty per cent. stronger-than that which is employed in the match portion. As soon as the slow fire of the match reaches the thread medium, 7

the latter burns with greater force and rapidity andignites the main charge of powder in the tube a. It is designed in this manner to insure the ignition of the charge in the squib. The tightness of the match junction is effectually counteracted. 1 Each branch of the double match is independent of the other in its burning, but the fire of both matches meets at the medium. The double match is usually formed by splitting that portion of the tube which extends beyond the thread from the powder-case a and immersing the branches in inflammable material. These branches have neither twist nor hardness, nor have they any recesses to receive and conceal loose powder. In this manner they are, therefore, formed to burn steadily and easily.

Having described :this invention, what I claim, and desire to secure by Letters Patent, 1s

1. A squib having at the end of the powdercase, where the match portion joins, a guard of thread saturated in quick-burning material and forming a medium to insure the lighting of the charge from the fire of the slow-burning match, substantially as specified.

2. A squib having at its end portion a double match, and where the branches of said match join the charge-case a guard and medium of quick-burning thread, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE SIMS REESE.
