SELF-ADJUSTING FIRING LANYARD FOR FIELD ARTILLERY. 
Sectional Elevation on A B. 
Scale 
a, a , are steel nuts, screwed into the gun. 
b, is a hinge. 
s, s, are the guides for sliding bar. 
z, is a fixing bolt held in by a split pin. 
x, the end of guide piece, is slightly turned up, so as to allow a fuze key or pricker to be 
inserted under it to lift up the guide piece if necessary to take it off. 
N.B.—The “ sliding bar ” is not shown in either of the above, so as to make 
them the more clear. 
The nut at the hinge b is undercut thus on the outside, so as to 
admit of the guide piece fitting underneath. By this method of ad¬ 
justment the whole thing can very rapidly be removed and replaced in 
the event of anything breaking. 
Tor tightening the vent a spanner shaped thus would be 
better suited than the one now in use, as it would not be 
necessary to remove any portion of the Tiring Lanyard. 
The advantages of this instrument over the ordinary tube lanyard 
and tube pocket are 
1. All appliances for firing are attached to the gun itself, so that 
in the event of 1STo. 3 being disabled another man can fill 
his place and at once carry on his duties without having 
to supply himself with anything from the person, of the 
disabled number. 
2. Time saved in making ready to fire. 
3. Insurance against miss-fire (the tube cannot be jerked out of 
the vent as the sliding bar can only move horizontally). 
4. Freedom of action to No. 3, who is not overloaded with imple¬ 
ments. 
5. Convenient position of fuze key for setting fuze before loading. 
6. Existing stores can be used (no special tube being required). 
The small fuze key attached to the end of the lanyard is 
only intended for fixrng the fuze, it will not remove the 
fuze from the shell, but this would never be required to be 
done at the gun. (This small fuze key seems to be more 
handy for setting the fuze.)
