40 HOW TO TAKE 



TO TAKE A LOCK TO PIECES. 



In the event of breaking or weakening a spring, and 

 therefore having to replace it with an extra one ; or, in 

 case the works of a lock should have become damaged 

 by rust and neglect, every sportsman should be provided 

 with a little spring-cramp, which may be carried with 

 his gun-case, and with which he may himself take his 

 locks to pieces, with as much safety as the first work- 

 man in London. I have, therefore, here given specific 

 directions, regularly numbered, by having which before 

 him he will, I trust, find it almost impossible to mis- 

 take, either in taking his locks to pieces, or putting 

 them together. 



TO TAKE OFF THE [HAMMER AND] SPRINGS. 



EN. B. In cramping springs, be sure never to confine them closer 

 than is absolutely necessary, otherwise you will soon weaken and 

 spoil them. 



MAINSPRING. 



To take off: 



1. Put lock to full cock. 



2. Cramp the mainspring. 



3. Let down the cock, and the mainspring will drop off. 



To put it on again : 



(Let cock be left down.) 



1. Hook the end of the mainspring on the swivel, or chain. 



2. Move it up, and into its position on the lock-plate. 



3. Unscrew the cramp, and the mainspring will be replaced 



for action. 



[HAMMER. 



To lake off: 



1. Shut down the hammer.
