To all whom it may concern:
Be it known that I, KARL Wrasse, a subject of the German Emperor, and a resident of Essen-Riittenscheid, Germany, have invented certain new and useful Improvements in Burning Time-Fuses, of which the following is a specification.
The present invention relates to burning time-fuses. It is customary to make the body of such fuses of comparatively soft metal; but it has been found that when rofuses are ed with great initial velocity the projectile bursts before the expiration of the ad usted time of burning. This is due to the fact that on firing the base of the fuse bends under the effect of its own inertia, thus creating an empty space between the base of the fuse and the priming-circle in the composition ring surmounting the disk, throu h which space the flame oi the priming-airs e passes to the channel in the leading to the detonatingchamber. The ignition of the charge is therefore not del yed till the burnin out of the part of the primingmircle whic corres ends to the adjusted time of'burning. On the contrary, the ignition of the charge takes place directly after the priming-circle has started burn ing.
The object of the present invention is 'to do away with the drawback above set forth. In he accompanying drawings I have, by the way of example, shown the invention applied to a fuse which is provided with one fixed composition ring and one rotatable composition ring. Figure 1 is a longitudinal section of the fuse and part of the projectile, the several parts bein shown in the fositi ons which they assume he ore firing; an Fig. 2 is a view corresponding to that shown in Fig. 1 showing how the shape of the base of the tuse is altered by firing.
The spindle A and the fuse-base B, which is integral with the spindle, are made from brass, aluminium, or other metal that is E, worked. In the upper part of the spini. which i rlosed by the cap C, the nipple ll sndihe prime-elicit E are arranged. On the windie a are placed the two composition rings F G, one of which, F, is
com position rings F G are arranged the primin -circles F G which are covered bv felt nonrotatably i'onnccted to the spindie by a pin H. In the plates J K. In the fuse-base B is the detonatmg-chamber 'L' and the channel M, leading theilgto. The above-described arrangement 1s 0 Between the fuse-base B and the composition G or the racking-plate K is arran ed an annular pateP, which must be me e from a material that is at'least as hard made and may be made from a mat i'ia of greater hardness; such as steel; The plate P is loosely inserted on the spindle A and lies in its entire width plate K and before firing also tightly against the fuse base B. The plate P is provided with a flash-hole or vent p, re istering with the priming-cricle G and with channel M. A pin which issituated ina bore in the late P hnd in thebase B, preventsthe plate rom turning relatively to the fuse-body A B when the composition ring G is adjusted or when the ojectile commences to rotate.
If a pro ectile rovided with-the improved fuse is fired with great initial velocity, the fuse-base B bends, as shown in Fig. 2 at the moment of'firingunder the inertia of the base and the spindle A. The plate P does not, however, alter its shapagiecause its mass is small and 'for the furth 1' reason, if made from steel, that it possesses much power of resistance. From the foregoi'n it follows that after firin he plate P stil lies tightly against the pitching-plate K, so as to prevent the premature communication of the fire from the priming-circle G to the flash-hole plate P thus pre- 2) and the channel M.

Having thus described the invention, the following is what is claimed as new therein: 1. In a time-burning fuse, the combination with the fuse-base having a powder-channel therein, of a composition ring having its priming-circle disposed on the side adjacent the base, and a protecting-ring formed of an incombustible material that will not become 1 distorted on firing, and located between the composition ring and the base. 2.
