PATENT OFFICE.
RAILWAY SIGNAL-FUSE.
Application filed September 1, 1920. Serial No. 407,558.
To all whom it may concern.
Beit known that I Fnnnnmc L. WANK- LYN, a subject of the g of Great Britain, andresident of the city of Montreal, Province of Quebec, Dominion of Canada,rhave invented certain new and useful Improvements in Railway Signal-Fusees; and I do hereby declare that the following is a full,
clear, and exact description thereof.
My invention relates .to railway signal,
fusees disclosed in my pending application Serial No. 367,019 for use particularly in railway signaling and adapted to be effective during the day as well as during the night by having combinedtherein smokeproducing and light-producing elements.
Some difiiculty' has been experienced in providing a fusee the dimensions of which conform to the requirements of the rail way commissions andv in which the smoke signal will be of a duration equal to that of the light signal and .it is the object of the present invention to overcome this difficulty by roviding a railway signal fusee of standar dimensions and constructed and arranged to produce a continuous flare or light signal and a series of successive smoke signals the latter covering a length of time equal the duration of the light signal.
To thisend my invention consists of the particular construction and arrangement of parts hereinafter described 'and pointed out in the drawing.
For full comprehension, however, of my invention reference must be had to the accompanying drawings in which- Figure 1 is a side elevation partly in vertical section of a fusee constructed according to my invention;
Fig. 2 is a transverse sectional view on line 2-2 Fig. 1; and
Fig. 3 is a similar view to Fig. 1 illustrating a modification.
My improved fusee consists of a tubular container 2 divided longitudinally by a partition 3 of ogee curvature in cross section, the latter constituting an integral art of the container which is constructed 0 an inflammable material such as pa er or the like. The lower end of the tu ular container is closed by a relatively heavy head 4 carrying the usual spike 5 while the oposite end of the container is adapted to l ie protected by a cap 6, the latter belng rovided with the usual iting substance i protec ed by a tape 8 which also serves to taken seal the cap thereon. One of the chambers of the container is completely filled with any well known light-producing mixture indlcated at 9 while the other chamber is filled with aseries of smoke producing ellets 10 and non-inflammable fillers 12, the latter filling the paces between the pellets which are uniform y distributed throughout the length of the'fusee. I
In order to successively ignite the pellets from the light-producing mixture, the op poslte ends of a slow match 13 are respectively connected to the light-producin mix-. ture and to each of the smoke pro ucing pellets so that as the former burns the slow matches will be successively ignited and in turn will ignite their respective pellets.
If desired my invention may be embodied in the construction illustrated in Fig. 3. In this embodiment the tubular container 1s not divided longitudinally into separate chambers, the pellets being embedded directly 1n the light-producing mixture.
It may be found desirable to provide each pellet with vertical perforations to promote combustiom 7 From the foregoing description it will be seen that 'the fusee is provided of uniform diameter throughout and in which an intermittent smoke signal will be produced covering a period of time equal to the duration of li ht signal.
What f claim is as follows:
1. A railway signal fusee containing a llght producing element extending throughout the length of the fusee and constructed and arranged to burn continuously and a series of smoke producing elements distributed throughout the length of the fusee.
' 2. A railway signal fusee containing a light producing element extending throughout the length of the fusee and constructed and arranged to burn continuously and a series of smoke producing elements distributed throughout the length of the fusee and constructed and arranged to be successively ignited as the light .producing element burns, and means in contact with said light producing element and with each of said smoke producin elements and constructed and arrange from the former.
3. A railway siglnal fusee divided lon itudinally into two 0 ambers one of said 0 amto ignite the latterhers containing a light roducing element constructed and arrange to burn continuously, the other chamber containin a series of smoke producing elements, an non-inflammable means spacing said smoke producin elements apart, said smoke producing e ements being constructed and arranged to be successively ignited as the light producing element burns.
4. A railway signal fusee consistin of a tubular container divided longitu inal'ly throughout its length into two chambers and having one end closed, a light producing element within one of said chambers and completely filling the same, a series of smoke producing elements located within the other of said chambers and uniformly spaced apart throughout the length of the same, a non-inflammable substance filling each of the spaces between the smoke producing elements, an ignition device effecting communication between each of said smoke roducing elements and the light producing element whereb the smoke producing elements areigmted as the light producing element burns, and a cap protecting one end of said fusee.
5. In a railway signal fusee, light-producing means adapted to burn continuously and smoke-produclng means adapted to burn intermittently.
In testimony whereof I have signed my name to this specification in the presence of two witnesses.
