RAILWAY SIGNAL-FUSEE.
Specification of Letters latcnt.
Patented an. 16,1912.
Application filed July 26, 1910, Serial No. 574,006. Renewed October 2 0,- 1911. Serial no. 655,749.
To all whom it may concern:
Be it known that I, ISADORE Nrnrrcn, a citizen of the United States, residing at Dorches ter, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Railway Signal-Fusees, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to improvements in railway signal fusees, the object of which is to provide asignal fusee with means which insures the ignition of the signal compound from the lighting or priming head, under .the severe weather conditions to which such signals are subjected in their practical use.
The present improvement is of practical utility with fusees having the usual burning compound which includes potassium chlorate, though it is particularly intended for use in that form of fusee compound and fusee disclosed and claimed in my 954,330 dated April 5th 1910 and 955,671 dated April 19th 1910, in which potassium perchlorate is used. In this latter type of fusee, the signal compound is not so readily lighted as in the former, and in the latter my present invention is of especial utility.
In the accompanying drawing-Figure 1 is a longitudinal central sectional view of a fusee which embodies my present invention. Fig. 2 is an enlarged sectional view of the head or lighting end of the improved fusee.
Referring now to the drawing, 1 is the usual paper tube in which the signal combustible compound is placed. So far as my present improvement is concerned, this combustible compound may be of any suitable mixture, though the mixture here disclosed is composed essentially of a coloring ingredient, a metallic nitrate, combined with sulfur, a carbohydrate and potassium perchlorate. Connected with one end of the tube 1 is the usual plug 3, having the spike 4. As here shown the tube 1 has its lighting end 5 crimped or turned in as shown at 6, though this maybe varied at will without affecting my present improvement. In this type of fuses there is a separating core 7 consisting chiefly of a perchlorate, though this is not essential to the present improvement. Surrounding this core 7 is a lighting stratum 8, and this core is united to the fusee compound by means of a peg 9, to bind the prim- Patents 1 ing or lighting head to the signal compound 2 to prevent the priming head shooting or skyrocketing, which tendency is due to the very'much more sensitive composition of which it is composed.
Thus far I have explained the form of fusee shown and described in my said Pate nt 955,671, and the usual form so far as a lighting head and binding peg is concerned. My present improvement consists in adding a function to this binding peg, by making it a means for-insuring the igniting of the fusee compound from the lighting head, as well as a binding medium. This is accomplished ..by so chemically treating it, that after being lighted by the priming or lighting head, it will contlnue to burn even when submerged end first into snow, slush or water immediately after the fusee is lighted, thereby insuring the lighting of the signal'compound, and preventing it from being extinguished under the most severe and adverse conditions.- This result is accomplished by saturating the binding peg with saltpeter and lead nitrate, preferably 6 parts of the former to 5 of the latter, though these proportions may be varied to some extent. The peg is preferably treated by being boiled in a solution'of said ingredients for about 12 hours, and then drained and dried.
Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A signal fusee comprising a tube, a signal compound therein, a lighting stratum at one end of the fusee and a wood peg satu-. rated with a combustible compound, the
.outer end ofthe wood peg united with the compound and conveys the fire from the lighting stratum to the signal compound.
2. A binding member for the lighting stratum and the signal compound of a signal fusee, consisting of a wood peg soaked and saturated with a combustible compound.
3. A binding member for the lighting stratum and signal compound of a slgnal fusee comprising a wood peg subjected; to a. hot
compound consisting essentially of saltpeter and lead nitrate to saturate it.with said solution for the purpose described.
4. A binding member for the lighting straturn and .the signal compound .of ia signal 'fusee, consistingof a wood peg subjected to a. hot compound comprising essentially saltpeter and lead nitrate until the peg is thoroughly saturated and impregnated throughout with the said-compound.
In testimony whereof I hereunto aflix my 20 signature in the presence of two witnesses.
ISAD'ORE NIDITCH.
