To all whom t may concern:

Be it known that we, HENRY M. KOLB and UHARLESFOEHL, ofthe city and county ofv --Philadelphia, State of Pennsylvania, have invented a new and useful Firearm, of which 'the following is a specification.

Our invention relates to a 'new and usefulfirearm; and it consists in means for locking n the jcylinder-support in order that the same may be positively held in alinement. t It further consists in locking the cylinder or extractor rod.

lf fIt Jurtherconsists of other novel details of construction, all as will be hereinafter fully set forth.

. Figure 1 represents a partial side elevation and -awpartial sectional view of a firearm shown as a revolver embodying'our inven- 1- tion. f Fig. 2 represents a partial elevation f20`- and partial sectional view of a portion of the .p revolver, showing the parts in a dierent positionrom that shown in Fig. 1. Fig. 3 represents a sectional view of a portion of the tions. Fig. 4 represents a bottom plan view SimilarA numerals of reference indicate cory responding parts in the figures.

Referring to the drawings, 1 designates the rame of the revolver, 2 the handle or stock,

-4 designates the hammer, which is pivotally mounted in the frame and is suitably acv-tuated by the spring 5.

6 designates a lug orv projectiony on the f hammerwithwhich is adapted to engage a le- -ver-arrn 7 of the dog 8, said dog being pivoti ally mounted in theframe and suitably actuated by a spring 9, said dog having a bolt 10 for a purpose as will be hereinafter eX` Uvplained.

. trigg 13 designates the 'cylinder of the revolver, is: Awhich is provided with a series of notches 14 5ov and with which the bolt 10 is adapted to en-- .'s, gage in successionas the cylinder is rotated in order toy hold the cylinder in alinement' 11 designates the trigger, which-has a suitvable projection 12, engaging with a suitable 45 4portion of the hammer 4 in order that the latter may be actuated by the movement of the with vthe barrel.

The cylinder is mounted upon the sleeve 15, saidv sleeve bein'gpivotally` connected with the rotary arm 16,` which hasllint'egral therewith or secured thereto a collar 17, which is adapted to rotateon thebarrel, whereby it will be seen that said `cylindersleeve and rotary arm-.may be moved to one fside for loading the `cylinderand kejecting the shells.

1'8 designates thecylinder or 1extractor rod,-which passes through the sleeve 1 5and has `la pin 19v adjacent its inner end which is adapted to abut against the ej ec'tor.- llate 20, carried by thetube 21, ywhich latter as slotsl 22 adjacent its' end, in which -s'aidpin is ada ted to move, said p in, having its en'd 23 ,slig tly reduced and passing through -asuitableopening in the plate-20,.is adapted to enter 1 a recessin theframe 1 of the revolver'for locking the cylinder and vparts at theinner end.

A spring24, surrounds the "tube 21 andrbears against the pin 19, tending to 'holdthejsame in position normally seen'in Fig, 3, it; being seen, however, that the rod 1'8"canbe pulled to theright from the position seeninfsaid Fig. 3 againstthe tension' oi-"they'spring, so that the end 23 thereof isreleased''rom the recess, whereby thecylinder 'ian'd theparts can be ,moved to one side, as 'before` stated,

said spring 24 serving further tojreturn the parts to their normal position -when'the rod 18 and ejector-plate 20 have 'been moved to the left, whichcan be'done after'the' cylinder has been swung out, said laction'beingfor the ur'pose of ej ecting theshells from' the cylinger., the saidrod 'being moved 4in this direction, carrying with it the ej ector`=plate 20 and ing against the spring 24, aswill beevident.

` 26 designates a lug onprojection on the vtrigger 11,]said'lug or projectionengaging with one end of the lever 27jwhich issuitably pivoted in-theframe of the revolver; and the vided' with a. suitable openingv 29 lirl-*ainvement with the passage intheramef-L,`E and said eXtractorfrod- 18fhaving a' reduced "neck roo i `or groove 30 so situated with-res ectft the `opening 2 9 and lthe1 `p'assagelin lt -e-{lvi'rame l that when the'rod is in'normal osition, as

seen in thefigures, thelsamef'will 'ea-linep lment with'sad'opening 29. l. .The "spring 31k bears against a suitable portion of the frame and surrounds the pin 28, which in the present instance is provided with a head 32, against which said spring acts, so that the locking-pin 28 is normally held in the position seen in Figs. 1 and 3.

By reason of the action of the spring 31, in addition to the Jfunction already described, upon the lever 27 it serves as a trigger-returnthat is to say, the end of saiddever 27 bearing on the projection 26 causes the trigger toreturn to its normal position, as seen in Fig. 1.

The operation of the device will be readily appreciated. When the parts are in the position seen in Fig. l-that is to say, with the hammer downthe cylinder or extractor rod 18, as well as the sleeve 15, upon which the time of starting the ire.

the cylinder is mounted and which is pivoted to the rotary arm 16, are not locked at their forward end, although the end 23 of the rod is in engagement with the frame 1; but by a slight pull upon the rod 18 to the right from its position seen in the figures of the drawings the end 23 is released from the frame 1, and the cylinder, with its coacting parts and the rod 18, can be moved to one side, swinging on the barrel 3 by reason ofthe collar of the rotary arm 16 being mounted thereon. The cylinder is then in position to receive the cartridges, and after loading the arts are thrown back to the position seen in ig. 1, the spring 24 immediately returning the rod 18 to the position seen in Fig. 3 with the end 23 engaged in the 1frame 1. The revolver is now ready for iiring. As the trigger 11 is pulled back the projection 12 raises the hammer 4 by reason of its engagement therewith, and at the same time the lug 6 acts upon the dog 8 in order to remove the bolt 10 from the notch 14, with which it is in engagement at As soon, however, as the lug 6 has passed the lever-arm 7 of the dog 8 the spring 9 acts upon the said dog in order to force the bolt 10 into engagement with the neXt notch 14, which is so spaced on the cylinder that one of the chambers of the cylinder is in alinement with the bore of the barrel 'at the proper time. By continued rearward movement of the trigger 1 1 1 the hammer 4 is released and is forced forward by the spring 5, striking the cartridge and firing the same. The leverarm 7 is formed of thin material and is resilient, so that the return movement of the hammer causes the lug 6 to press the lever-arm 7 to one side to permit proper movement of the parts. It will be note that as soon as the trigger 11 is started on its rearward movement the end of the lever 27 in engagement with the lug 26 is depressed, raising the opposite end of said lever, which thus elevates the locking-pin 28 and overcomes the tension of the spring 31. The pin 28 will be thus passed through the opening 29 in the sleeve 15, which is the cylinder-support, and enters the groove 30 in the eXtractor-rod, it bein seen that by this provision the forward en of the cylinder-support and the cylinder are positively locked 1n osition, as well as the extractor-rod 18, so t at the same cannot be moved in either direction. The hammer is released or tripped at a suitable point in the rearward movement of the trigger, while the latter is still held in its rearward position until after firing, whereby the locking-pin 28 is held in elevated position, whereby the cy linder and its support, as well as the cylinderrod, is positively locked and absolutely insures proper iiring of the revolver, it being noticed that by reason of the locking of the rod 18 the rear end 23 thereof cannot be removed rom the recess in the frame 1, with evident results. As soon as the trigger is released, in addition to the usual return, the spring 31, acting through the lever 27 and pm 28, serves as a trigger-return, at the same time removing the pin 28 Jfrom engagement with the cylinder su port or sleeve and rod 18. It will thus e seen that the locking of the parts occurs at each iiring and is automatic in its action. It will be further seen that by the construction and arrangement of the parts that it is necessary for the pin 28 to enter the recess in the rod in order that the iiring may take place, so that in addition the locking the parts when fLring the construction prevents iiring unless the parts are in proper position therefor, as should the recess 30 not be in proper position to receive the pin 28 the latter when elevated would abut against the rod 18, and thus would be stopped from further upward movement, so that the hammer will not be released, as will beevident, and thus the iirearm cannot be discharged. It will thus be seen that until the parts are in proper position discharge is prevented.

It will be evident that various changes may be made by those skilled in the art which will come within the scope of our invention, and we do not, therefore, desire to be limited in every instance to the exact construction herein shown and described.

Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is
