DESCRIPTION OF BOXER’S 2 -inch TIME FUZE 
FOR 
RIFLED ORDNANCE. 
BY CAPTAIN VIVIAN DERING MAJENDIE, R.A. 
CAPTAIN INSTRUCTOR, ROYAL LABORATORY. 
A new fuze having recently been adopted for use with the 7-in. (110-pr.) 
Armstrong shells, 1 and the means of access to sections or specimens of this 
fuze, or other opportunities of becoming acquainted with its construction, 
being wanting to many Officers in the Regiment, I have thought that the 
following description might be acceptable, and perhaps, in some cases, 
useful. 
As this fuze is merely a modification of Boxer's common fuze, with which 
those for whose use the following paper is contributed are no doubt perfectly 
familiar, I have, as it were, built my description upon the common fuze, not 
dwelling upon the details which are common to the two, but enumerating and 
explaining the points in which this fuze differs from the common. 
This fuze resembles Boxer's common fuze in its general features and 
construction, but differs from it in several points of detail. 
The points of difference may be most conveniently explained by arranging 
them under the following heads :—■ 
(1) Points of difference in the head of the fuze. 
(2) do do body do 
(3) General dimensions. 
As regards (I) The head of the fuze :—The principal difference here consists 
in the method of ignition : Time fuzes for smooth-bore guns are ignited by 
the flash of the discharge, but owing to the absence of windage in Armstrong 
guns the fuzes intended to be used with them must be ignited by some 
other agency; accordingly a detonating arrangement is provided in the head 
of this fuze, by which it is fired. The arrangement is called a “ detonator" 
1 Col. Boxer, tlie inventor of the fuze, proposed it for use with all Armstrong shells; and it is not 
impossible that fuzes of this construction may ultimately be employed with the lower natures.
