Be it knewn that I, ROBERT IsBELI. HAMP- TON, of Athens, ,county-of Clarke, State of Georgia, have invented certain new and useful'Improvemeuts in Breech-Loading Guns, ofj which the following is a fulland exact description, reference being had to the-accompanying drawings, making part of this specification.

' fourth, to 'provide an automatic trigger-bolting device which can be made independent at will; and,-fth', to .supply the' means of taking uplost motion from wear in the hinge-piu, fore-stock, and lockffast action. In the accompanying drawings, Figure 1 is aside view oi'- the gun with the lock-plate removed, showing the parts in `proper relation with the hammer at full-cock.

lever.

The breech is constructed to furnish a re ccptaele for the lock mechanism, and the ham mer B, which is mounted therein, is provided between'its pivotal point and'heel with au vangular notch, C, which notch is arranged" at such distance from the pivot or axis as to cause the least amount of friction and consequent wear upon the scar, by which it is engaged. The notch C at its lower rear face is cut away to form an inclined surface, G, hereinafter referred to. The hammer 'is further provided between the notch C and the pivot with a Y notch, C,'.with which one end of the combined main and 4sear spring engages, and on its rear facelwithfa semicircular notch or recess, H', to be engaged by the bolt H, also hereinafter referred to. The hammer B extends forward into the stock under the barrels, and at its forward endl is provided with a cam projection,

M, extending inward from its side face into position to be engaged by a cam, I, onthe ejector-lever J, and bynieans of .which the hammer is cocked or forced into position to be engaged bythe scar-D, and engage with the safety locking-boltH.

The ejector'lever J is pivoted to the proj ection K on lthe barrels, is so placed that its upper end will engage the rod p of the ejector N, and is provided below with an outward-pro-y jecting cam, I, before '-referredto. An' angu lar switch-block, O, having its pivotalpoint at the angle, as shown at O, is provided at its lower or depending end with an inclined, projection, O", there being a horizontal arm,

O, extending rearward over said projection,

. and in such position that the toe of the hammer in being forced upward by' the'ejector-le` ver. willlengage the arm O and fofrce and hold the inclined projection out flush with the face of the guide-block L,which facilitates theeasy movement of the cam I of the ejector-lever on i its return with the closing of the barrels. The switch-block 0, consequent `to the engagement of the toe of the hammer therewith, performs 4the additional function of preventing the main-l -spring from i Aoperating the ejector` whenl the barrel has notfbeen red, for so lon as the hammerB remains at full-cock the malnspring E is prevented from operating .thegejector-lever, and, 'as a consequence, when 1t is desire to remove an unred cartridge, on opening the barrels the same will only be presented or forced out far enough to beremoved bythe ngers. .A switch, P, is employed to'accomplish'the same end when it is desired to save ,the empty shells, which consists of apin passing through from the side of the breech-frame andhaving that portion adj aeent to the switchblock made in semicircular form, and by turning either the rounded 'or the a'ttened face toward the switch-blockthe ejector is permitted either to apt forcibly to eject the shells or simply to push them out sufficiently to be re- By setting thefeathered portion of the arrowV show-n in line with the head on the side of the' breech-block pointingdownward the ,rounded surface of the pin willv bebrought opposite the switch-block, and consequently 'hold the same" Outland` prevent the ejector-lever from .being thrown itsil full extent by the vaction ofthe mainsp'ri'u'g; but when it is desiredforcibly to 4elect .the shells the pin is turned to `present the portion opposite. the switch-block, winch will allow .theswitehdull play', and in this way, as eachfbarrel is 'provided withaseparate ej eetor and an independently-oporating spring, it will be seen that either or bot barrels maybe convertedintoa non=ejector at will.

The Sear D is mounted li-n the breech-frame 1n lposition-to engage the hammer, .and is pro'-l vvided with a suitable notch toengage .one end of the combined main andgsear spring'E, the other end, which engages'Lffjaudv -operates the hammer, passing througha mortise .or slot in the sear,'caus`ing .the scarto-act as-a crampv link for saidspring.- The Sear has a rear ex-. tenslon, D', engaging a notch formed ina rear extension of the trigger, The hammer having been cocked or caused to engage with thelsear, as before stated, :is released therefrom by the trigger F, by pulling which the 'sear` is made will be .readily understood', and the force of the mainspring E carries the hammer forward until it nearly reaches the iiring-pin,when the force of the mainspring is arrested by the mortise in the sear acting as a crampi-link,l as before stated, the hammer being carried forward -by its momentum until itstrikes the firing pin. In this movement, the point of the Sear having passed off the arc leading to the bent notch in the hammer resting against the inclined surface at G, before referred to, both ends of the spring are exerted in forcing the hammer.

A tubular bolt, H, is employed to engage the semicircnlar recess IEP-in the hammer to' forma safetv-lock to the This bolt H is'notched at the point where it engages the hammer, and is provided on its inner end with a crank-pin or-'projection, h.' which engagesaslot, h', formed in the end of an upward-curved lextension of the trigger, and by which said bolt .is rotated to engage the hammer or release the same. When the bolt is rotated to engage the hammer, the semicircular face or unbroken surface of the bolt is caused to rest in the notchaud securely bolts the hammer against accidental discharge but when the trigger is pulled it causes the,v

bolt to be rotatedand turns the-notched por-v tion into line with recess, so that the hammer is left free to be acted upon by thespring.- The outerv end of thebolt H 'passes through 'the where locked, the letters A Ffbeing .out in'th'efend the ietrerss n on th;e 10erT the Word-safel orfany or deviceindibating this fact".'fis 4 stamped, which indioatesthat.thehammerjsl plate, one/on each44 side,- and in suchv manner f gaged by a' sector, S, which-sector is- T'."

A-sliding bolt .or trip-rod, V, ismoullted in',v bearings in the breechframe and is. connected' 'and operated from the forward-extending arm of the leverU, the bolt being adapted to engagea perforationy or hole, X, in the sector S.

:The trip-lever U is always under tension, and js forced down and h eld by the projection K' to slip out of the bent notch C in a manner that j on the barrels when closed; but when the le` ver is turned to. operate thesector, and through it the bolt R, the rear upper end of the trip-lever V is forced backward by the tension of the spring, 'raising the vforward extending end,

'and consequently the sliding bolt or trip-rod l"which action allows the sprl-ng W, acting on threaded perforation in the top of the breechf thesectonto'force the bolt R home and lock the barrels securely.

lV A set-screw, Y, is employed to engage the annular bolt and take up lost motion from wear' thereon. This screw Y passes through a frame in position to engage the upper face of the annular bol-t, and as said bolt or its supporting-face wears the screw can be turned in to compensate for any lost motion consequent thereto.

of the trigger, the said end being simultan` ously depressed by the engagement of the rear extension of the sear therewith, and in4 this position is held van'd locked until released by theoperator through the thumb-piece 02.-. This automatic feature -may be regulated at'will by means of a segmental pin,d, which is arranged in such manner as to be adapted to engage the rear face of the trip-lever U and hold the same from engaging the sliding plate a, and thereby prevent the operationof the triggr- Thehead of the pinis markedwith an arrowwhere it extends through the'breechframe under the lever T, so that the operator can tell how to set the pin.

The thumb-piece a? may be used to lock thetrigger at any time whenthegunhas been cocked without the use of the automatic arrangement.

The triggerbolt b is held firmly in position, locked or unlocked, by the closed end of the spring E resting against the under side ofthe trigger-bolt spindleEz, and from this, in con- 'also as a hammerbolt spring, while, sixth, it also, as above stated, holds the trigger-bolt spindle locked or unlocked.
