DAVID A. GRANT,- OEPHILADELPHIA, PENNSYLVANIA.-
nnnen-iinrncrne MEANS non rims-roses.
'To all whom it may concern:
Be it known that 1, DAVID A. GRANna V citizen of '-lthe United States, residing at Philadelphia, in the county of Philadelphia 'andState of Pennsylvania, have invented certain new and'useful Improvements in Range-Defacing Means for Time-Fuses, of which the following is a specification.
My invention relates to time fuses used for igniting shells,'projectiles, shrapnel and the like, and particularly to time fuses employing a rotatable member which is set in a a certain position in relation to a fixed member time of the explosion of the to determine the shell.
Time fuses are provided with agraduated scale, usually located upon the fixed memberor body portion, said scale indicating seconds of time, and the opposite, or rotatable meinber, is provided with an arrow. or indicatI-- 'ing point. -The rotatable member may be i turned to bring the arrow adjacent to any desired point upon the graduated scale, and
thus set the fuse to explode at a specified time. v The object of my invention is to construct a time fuse in such a manner that the indicating point or the graduated scale may be removed or defaced after the fuse is set and before the shell is fired from the gun, to destroy-all evidence of the time allowed when setting the fuse, for the travel of the shell from the gun to the-place where the shell hits. The purpose of this is to prevent the enemy from obtaining the range at which the fuse is set by examining the indicating marks upon the fuse of an unexploded shell,
and thus obtaining the firing range.
In the accompanying drawings Figure 1, is a side elevation of a fuse showing my improved detachable band or sleeve secured to the body portion of the fuse; and having the graduated scale formed upon said band; Fig. 2 is a similar view showing the detachable band secured to the rotatable timing ring of the fuse, and having a single indicatin mark upon the band, the graduated scale being formed upon the body portion of the fuse in the usual manner; Fig. 3 is a perspective view of the band or sleeve, detached. Fig. 4, is a side elevation of a fuse, drawn on a smaller scale, showing two detachable bands, one thereof secured upon the rotatable ring and the other secured upon the body portion of the fuse; and Fig. 5 illustrates a different method of carrying out my invenspecifieationojfletters Patent.
Referring to the drawings which like references refer to like parts, 1 represents BatentedAug. 28,1917.
Application filed April 13, 1916. Serial N 0. 90,823.
' tion, by providing a removable indicating 1 the detachable 'metal'band or sleeve upon which are shown graduations indicating seconds of time,and also having a second scale indicating yards; The band 1 is adapted to be secured to a-time fuse, as show-n in'Fig. 1.
The fuse shown in the drawing consists of I a body portion 2,.provided with a threaded shank 3, for securingthe fuse in a shell or" projectile.- The body portion 2 is provided withthe nose portion 4 which is rigidly secured in the body portion 2. Between the bodyportion 2 and the nose portion 4, of the fuse is formed anannular groove in which is rotatably mounted the timing ring 5 and havingan arrow --or mark 6 formed thereon.
The timing ring 5 is'rotated so as to bring the-arrow 6 to anyide'sire point upon the graduated'scale upon the band 1. This will govern thetime requiredfor the fuse to explode after it has been' firedfrom the gun.
In Fig. 2 my" improved graduated band l is shownsecured to the rotatable timing ring 5 and: the: arrow 7 is shown located upon the band and-used. upon a fuse having the graduated scale located upon the body portion in v the usual manner. a The-metal band 1 may be made circular but I prefer to make it in a flat strip and secure the ends thereof together, so that the lpand may be more readily removed from the use.
In the drawings I have shown the metal band 1, with a fastening device consisting of a tongue 9 formed upon one end of the band and the opposite end of the band is shown with an aperture 10 formed therein to receive the tongue 9, which latter is bent over upon itself after it has been passed through the said aperture. This will hold the ends of the band together and the band lmay be readily removed by tearing oil the tongue or straightening out the tongue so that it may be withdrawn through the aper turning upon the fuse.
Any suitable form 0ffastening- "device 1 may be employed for securing the bandupon the fuse Without departingfrommy invenns T e r me ahl rband ma e attached to either the fixed part'of the fuseor to the rotatable part and it maybesos. arranged, that the detachable sleeve Willcarry a single:
