FUZE or FusE, an appliance for firing See also:explosives in See also:blasting operations, military shells, &c. (see BLASTING and See also:AMMUNITION, § See also:Shell). The spelling is not governed by authority, but See also:modern convenience has dictated the See also:adoption of the " z " by military See also:engineers as a See also:general See also:rule, in See also:order to distinguish this sense from that of melting by See also:heat (see below). The word, according to the New See also:English See also:Dictionary, is one of the forms in which the See also:Lat. fusus, spindle, has been adapted through Romanic into English, the See also:ordinary fuze taking the shape of a spindle-like See also:tube. Similarly the See also:term "fusee" (Fr. fusee, spindle full of See also:tow, See also:Late Lat. fusata) is applied to a coned spindle sometimes used in the See also:wheel See also:train of watches and See also:spring clocks to equalize the See also:action of the mainspring (see See also:WATCH); and the application of the same term to a See also:special See also:kind of match may also be due to its resemblance to a spindle. Again, in See also:heraldry, another See also:form, " fusil," derived through the See also:French from a Late Lat. diminutive (fusillus or fusellus) of this same fuses, is used of a bearing, an elongated See also:lozenge. According to other etymological authorities, however (see See also:Skeat, Etym. Dict., 1898), " fuze " or " fuse," and " fusee " in the sense of match, are all forms derived through the Fr. fusil, from Late Lat. focile, See also:steel for striking See also:fire from a See also:flint, from Lat. See also:focus, See also:hearth. The Fr. fusil and English " fusil " were thus transferred to the " firelock," i.e. the See also:light See also:musket of the 17th See also:century (see See also:FUSILIER). In See also:electrical See also:engineering a " fuse " (always so spelled) is a safety See also:device, commonly consisting of a See also:strip or See also:wire of easily fusible See also:metal, which melts and thus interrupts the See also:circuit of which it forms See also:part, whenever that circuit, through some See also:accident or derangement, is caused to carry a current larger than that for Which it is intended. In this sense the word must be connected with fusus, the past participle of Lat. fundere, to pour, whence comes the verb " fuse," to melt by heat, often used figuratively in the sense of blend, mix.
