REVOLVER.

SPECIFICATION forming* part Of Letters Patent No. 652,625, dated June 26, 1900.

` Application led February 9, 1900. Serial No. 41648. (No model.)

To all whom/zt may concerm.

' Beit known thatvI, CHRISTOPHER D. Mo- DONALD, of Vance, in thejcounty of San Miguel-and State of Colorado, have invented a newand useful Improvement in Revolvers,

l of which the following is -a specification.

'My invention is in the nature of animprovement upon the revolver forwhch I have in ade application for Lett-ers` Patent of the United States, Serial No. 725,091, which application was filed July 25, 1899, and allowed September 2D, 1899. In this application I de'- scribed and claimed a revolver in which the handle portion is provided with rigidly-at` tached upper and lower extensions inclosing the cylinder-space, and the-barrel 'is hinged on a vertical axis between the forward ends of said rigid extensions and bears the revolv-4 ing cylinder, which swings out when the barrel is deflected aboutv said joint at the two forward extensions of the handle. My present invention employs this same general principle of construction, 'but provides an improved means of articulation, `as will be hereinafter more fully described with refer-i ence to the drawings, in which- Figure l is a side view, partly broken away. Fig. 2 is a plan view with the barrel turned to one side in Vdotted lines. Fig.` 3 is a partial longitudinal section on line 3 3 of Fig.

2. Fig. et is atransverse section through line 44; and Figsj and 6 are 'plan viewsof the rear portion of the barrel, partly broken away to show the means for jointin g the barrel to the handle extensions.

In the drawings, A represents the' Darrel,

`carrying the cylinder C, and B is the handle,

having rigid forwardextensionsb and b', in-` of whichv extensions the' barrel. is -jointed about a vertical axis, as shown and described vin my former application referred to.

In my present invention one -side `of the rear endof the barrel is madewith a lateral projection a, in which is formed an elongated chamber opening at the upper edge of the barrel, containing a horizon-tal locking-bar a', havinga thumb-piece or lip-o1.3 extending through a notched portion of 'the barrel ont to the edge ofthe same. In the elongated chamber, beneath the locking-'bar a, is an elliptical spring a2,which makes the bar spring. seated, normally holding it up in locking po# sition toprevent the barrel from being'turned on its axis of articulation, butcapable of bein'g depressed by the thumb, so as to allow the rear end of the barrel to pass under the forward extension b of the handle.-

The articulated joint of the barrelis formed at the lower side by a simple screw. f, connecting the lower extension b' of the handle to thevlower lug of the barrel. At'tho upper side, however, there is a peculiarly-formed joint, as follows: Thefupper extension b of the handle is recessed at b2 on its upper side, which portion passes under an overhanging part a4 on the rear end of thezbarrel. The

lower side of the extension b is formed at its vextreme end with a circular boss b3, which sition shownin Fig. 5. A locking-slide e, f'

Fig'. 5, is then slipped sidewise into the opening d and when fully in is fastened by a screw e., asin Fig. 6, and retains the block d, behind the bosser joint-bearing b3. To take the revolver -to pieces, the screw -e is taken out 4and the slide e and block d removed through theoutletd', andthe screw f of the lower joint beingremoved the boss or bearing b3`can Abe ydrawn back and 4taken out .through the opening d'. closing the cylinder, and to the forward ends When "thebarrel is in true Valinement, the long locking-bar af is forced up by `its -subjacent spring a2 and by bearing against the sidefof the upper extension b holds the barrel firmly' inalinement, so that it cannot be bent :on its joint, andthe long bearing which the bara aiords makes a very strong. lock and holds the barrel firmly in alinement.

In breaking the revolver for ejectiug the shells and reloading` the handle is taken in the righthandand the barrel in the left, with the thumb of the left hand resting upon the .lip as of the spring-seated locking-bar, and

IOC

it Will be seen that all the parts are so organized as to enable this action to be quickly and most conveniently effected.

l Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A revolver having a handle with a rigid extension beyond the cylinder, and formed with a pivot-boss on its lower side at the end, a barrel having a recessed upper surface at the rear end with a side outlet, a detachable bearing block adapted to be introduced through this side outlet and pushed up to the boss, and a laterally-inserted locking-slide for the bearing-block substantially as def scribed.

:2. An articulatedjoint fora revolver, consisting of a barrel having an overhanging rear end {t and a right-angn'larly-recessed chamber bcneat'lit With'lateral outlet, a handle extension l) With recessed upper surface lf3 and boss Ui, and the detachable bearing d arranged to be inserted through the lateral outlet and pushed up to contact against the boss, and the locking-piece c inserted laterally behind the 4bearing (l substantially as and for the purpose described.

In testimony whereof I have signed my name to this specilicationin the presence of two subscribing Witnesses.
