Fig.5 is ndetail riew ver 15, preferably formed integral with the of one of the parts. spindle, as shown, and adaptedto rest upon The reference -numeral l designates the the rear portion 16 oft-he breech-frame. This breech-frame, and :l the barrels, having the rear extension 16 of the frame is formed with rpo 5o usual pivotalconnection with the frame lat an elongated slot 16 to receive the safety- 'the point 3. slide 16, adapted to be emtahlyoonneched so jecting portion 13 of the bolt 12 extends `3o restore the gun to locked position, the barwith the trigger, (not shown,) and said safetyslide has a connection with the oscillatory lboking-bolt, consisting of a rod 17,'support-A ed below the rear extension 16 of the breech 5 frame by means ot a depending eye'l. A .coil-spring 18 surrounds the rod 17, one end bearing against the eye 17'* and the -opposite end agsinita nut 18, the latter being adj'nstable upon the rod to regulate the tension ro ot the spring. It will be seen that the rear end ofthe rod 17 bears against the safetyslide 16, while its forward end -impingee against the locking-bolt, thus insuring 'the movement of the slide when the bolt is oscil x5 lated.

The utility, operation, and functions of theV mechanism thus far described will now beexplained.

When thegun is in locked position, the pro.-

.through'the opening in the barrel-lug, as shown inFigs; 1 and 2, and by moving the lever laterally the b olt is oscillnted to release the barrels and permit the gun to be z5 broken down. When the presen re upon the,

spring 7 is thus released, the post is projected upward, bringing the beveled shoulderG thereof in contact with the lip 1l* to lock the bolt in its unlocked position. To

rels are tilted on the pivot 3, causing the lug 14 to strike the upper end of the pin 6, depressing said pin and the cylindrical post 5 and compressing the spring 7. The bolt 1:. is thus released and is then oscillated by means of the spring-actuated rod 17 engaging the barrel-lug. The beveled surface of the shoulder 6 is held closely against the lip l1l when the gun is in unlocked' position, and fo the upward force of the 'spring insures this close contact, thus compensating for wear upon these coperating elements. A furtherimportantfeatn re of my improved lconstruction is the eccentric surface 12 of 5 the slot in the lockingbolt. lf this surface were parallel with the opposite wall of the slot and concentric with the spindle, slight wear upon the surface 1S." would result in a loose locking connection. By inclining the surface 12 l, as shown and described, and having the spindle inclined rearward aldownward and .nearward'lockiug strain is applied to the bar- :g1-1i .ig and wear upon the bolt is compensated neces It will be obvious that the safety-slide will be operated simultaneously with the m`ovement of the locking-bolt through the rod 17.

I claimil. In a breechfioadingbreakdown hammerlees gun, the combination with the barrel-lug, of an oscillatory spindie supported in an inclined position within thc breech frame,- a lockinzbolt mounted on' said spindle, a post to receive the impact of the barrel-lug, said post having an annular beveled shoulder, and a stop device carried by the spindle.

2. In a breech-loadin g breakdown hammerless gun, the combination with the barrel-lug, of. an oscillatory spindle supported in au inclined position within the breeclurame', a locking-bolt mounted on the spindle, a post to receive the impact of the barrel comprising a hollow cylinder having a beveled shoulder,

' and a projecting pin, a bifurcated plug, with-v in the cylinder, a spring within the cylinder, and a stop device carried by the spindle. 3. In a bresch-load'in g breakdown hammerl les gun, the combination with the 'harrelduml of an oscillatory spindle supported in an in clined position Within the breech-fratne, a locking-bolt mounted on the spindle, and constrncted to engage the barrel-lug, a yielding post to receive the impact of the barrel-lug and formed with an annular beveled shoulder, a stop device carried by the spindle and adapted to engage the post, a safetyslide and a connection between said slide and the locking-bolt.

4. In a breech-loading breakdown gun, the combination with the stop-arm carried by the spindle of the locking-lever, of a spring-actuated stop-post which is formed with au annular beveled shoulder at its point of lockingcontact with the said stop-arm, so as to compensate for wear.

5. ln a breech-loading breakdown hammerleas `gun, the combination with the barrellocking bolt, of a push-rod bearing at one end againstl said bolt, and connected at its oppositeend to the safety-slide, and a spring for etl'ecting the longitudinal movement of said XL In testimony whereof I allix my signature in presence of two witnesses.
