48 HOW TO TAKE A LOCK TO PIECES. 



4. Put in the scear; to open a clear passage for the screw of 

 which, you must observe the same pressure of the fore- 

 finger and thumb on the scear and scear-spring, and 

 the pushing of the cock forward, as before described for 

 taking off the scear. 



The reason for this pressure being required, to put in the scear, 

 is, to get the hole in the scear opposite the hole in the bridle, so 

 as to admit the scear-screw to pass freely. What most frequently 

 puzzles people, who are not used to mechanics, is, that they 

 neglect to keep pressing the cock forward, and by that means the 

 scear is constantly slipping out of the tumbler, and they are plagued 

 to get the holes in a line, to which they would immediately be 

 brought by the pressing forward of the cock, and the pressing in- 

 ward of the scear.

LET DOWN the cock, to put on the mainspring, as before 

 directed, and your lock will have every thing in its 

 place. 



Observe well, that except the pressure required to put in the 

 scear, which is the only part in the least difficult, there should be 

 no force whatever used with the works of a gunlock. 



With detonating guns, however, we have but half the trouble, 

 and the only extra dissection that may be required for those which 

 are now most usually made is, to screw out the nipple or pivot 

 with a small wrench or key. 



In doing all this, or indeed any thing to a gun, it is 

 advisable to put on an old pair of gloves, as the warmth 

 of the skin is apt to produce rust, and the hand, with 

 the glove on, has a better purchase for taking out the 

 scear. 



As a key to the foregoing directions, the following is 

 an alphabetical list of the proper names for the principal 

 parts of a gun, which may not be universally known 

 among sportsmen.
