The Shot- Gun. 



grip, B, with the lug, F, prevents any and all springing of the barrels 

 and breech at this point. Any wear on B can be taken up by tight- 

 ening nut, E, without altering the position of C; and any wear on C, 

 by screwing downward the second nut, E, on shank of B, without 

 altering position of B. To prevent the nut, E, from getting loose, a 

 steel washer with a tongue fits between it and the face of the breech. 

 Thus, with the two pieces B and C and the nuts E E is formed a perfect 

 double-grip action, allowing compensation for wear, requiring nothing 

 further, if strength alone is considered. To keep the grips and the 

 lug, F, and hook, D, from wearing by continual contact, stop L enters 

 into a notch on the underside of grip, C, when the gun is opened, 

 holding the grip out of the way until the barrels are brought home, 

 when L is depressed by lower lug, D, and the grips allowed to swing 

 into their locking position. The gun is made self-closing by the 

 spring, K, bearing against a stud on C, bringing the grips home when 

 released from the hold of L. The strain on the hinge when the 

 barrels drop is entirely obviated by the shoulder-lug, D, coming in 

 contact with check, J. This check works exactly like the bolt which 

 holds the front stock to the barrels. Wear on hinge is taken up by 

 compensating hinge-bolt. 



Mr. Sneider claims for this action : That with four pieces, B, E, 

 E, C, a perfect double-grip gun is formed ; that, without affecting the 

 strength of the action, it is made self-closing, by spring, K, and 

 the movement, and consequently the wear upon the parts lessened 

 exactly one-half by the introduction of stop, L ; that the strain on 

 the hinge-bolt is entirely overcome by check, J; and that means of 

 compensation is supplied at every point where wear can occur in a 

 breech-loader — on B by nut E, on C by nut. and on hinge-bolt by
