FIREARIVI.

To all whom t may concern.'

Be it known that we, EDWARD B. LEGGETT and THOMAS WV. APPLEYARD, citizens of the United States, and residents of the borough of Brooklyn of the city and State of New York, have invented new and useful Improvements in Firearms, of which the following is a specification, reference being made to the accompanying drawings, forming a part thereof.

The invention relates to lire arms in general and particularly to that t-ype known as revolvers.

This invention is directed to the following enumerated features and also to other features not specifically enumerated at this point but all of which are clearly described and set forth in the specification and claims forming a part thereof. Some of the features thus referred to are, a, the means for locking the rear end of the barrel to the frame; o, the hammer and operating mechanism therefor; c, the means for locking the rear end of the cylinder, at the central portion, to the frame of the fire arm at a time when the firing is to take place, said means also being connected to the firing pin and operable by the hammer; CZ, the means for holding the cylinder from rotating and also for holding the cylinder so that a cartridge hole in the cylinder is in proper position relative to the bore of the barrel at the time of firing and, e, the means for retaining the cylinder in place upon the barrel at the time the cartridge shells are being extracted from the cylinder by the extractor.

In the drawings above referred to, Figure l is a side view of the revolver partly in section showing the positions the parts normally occupy when the revolver is not being used. Fig. 2 is a view similar to Fig. l showing the position the parts occupy prior to the release of the hammer before firing. Fig. 3 is a side view partly in section of a part of the revolver showing the means for retaining the cylinder in place on the barrel and also the means for locking the rear end of the barrel to the frame. Fig. 4l is a side view partly in section of a part of the revolver showing the position which the member for retaining the cylinder upon the barrel occupies when the cylinder is being removed from, the barrel. Fig. 5 is a sectional view taken on line 5-5 of Fig. 2.

Serial No. 587,807.

Fig. 6 is a sectional view showing the posi tion of the cylinder, frame, and combined firing pin and locking bolt at the time of Fig. 7 represents detail views of the combined firing pin and locking means, and Fig. S shows front and side views of the hand, the lifter, the spring therebetween and a part of the trigger.

The vframe of the revolver is designated by l and upon this is pivotally mounted the barrel 2 carrying a cylinder 23. This cylinder is provided with any well known type of shell extracting means and as the same is not the subject of my invention it will not be further described.

In order to lock the rear end 5 of the barrel 2 to the frame l, the latter is provided with a projection 3 which is slotted and also with a recess portion 3a. The rear end 5 of the barrel is shaped so as to lit the frame and is recessed so as to receive the projection 3 carried by the frame. This rear portion of the barrel is also provided with a sliding spring pressed bolt 4 which is flattened at 4b so as to enter the slot of the projection when forced forward against the spring by pressure applied to the part 4d, and when the rear portion of the barrel is being swung to normal position. This bolt is also so formed that when the barrel and frame are in normal position relative to each other a part 4 of the bolt will enter the recess 3il and part 4C of the bolt will engage overhanging portions on the projection 3 and thereby form a double locking means between the barrel and frame.

A folding trigOer 7 is pivoted at 7a to the frame and on the rear end thereof there is pivotally mounted the front scar or lifter 8 and the hand 20. The front searl or lifter 8 and the hand 2O are pressed apart by the spring 2l and are so arranged that when the trigger is pulled the sear or lifter will force back the hammer and simultaneously therewith cause a revolving of the cylinder 23. But the revolving of the cylinder will not take place until after the cylinder stop 25 has been withdrawn from the notch 24, in the cylinder 23, in a manner which will be hereinafter described.

The hammer 6 is continually forced forward by a spring pressed rod l1 and is pivotally connected at the point l()il to an actuating lever 10, which is pivoted on the frame at point 9. Both the actuating lever and the hammer are provided with o-penings larger than the pivot or fulcrum member at 9 into which said member enters. The free forward end of the actuating lever 10 has a slidable engagement with the rear end of the trigger 7 and a pull upon the latter will impart an upward movement to the forward end of the actuating lever and a downward movement of the rear portion to which the hammer 6 is pivotally connected since the actuating lever swings about the pivot or fulcrum member at 9. The pull on the trigger will also cause the front sear or lifter S to press upon the hammer and force it against the pressure of the spring pressed rod and this will cause the hammer to swing around the pivotal point 10a, which has been lowered, until the pivot or fulcrum member at 9 is in the lower portion of the openings referred to. Now when the front sear or lifter disengages from the hammer the latter will be forced forward and downward due to the spring pressed rod and the forward end of the hammer will engage the combined firing pin and locking bolt at the point 12a and will force them to firing and cylinder locking position. This engagement of the combined firing pin and locking bolt by the forward end of the hammer will take place due to the fact that the point 10EL around which the hammer swings has been lowered and due to the fact that this swinging can take place since the opening in the hammer 6 in which the pivot or fulcrum member at 9 is located will permit the swinging movement of the hammer. The opening in the actuating lever is made larger than the pivotal or fulcrum member at 9 to permit a change in distance between the pivot or fulcrum member at 9 and the pivotal connection between the hammer and lever at the point 10a so that the hammer can swing freely forward without any cramping taking place between the two said points due to the walls which define the opening in the hammer being at variable distances from the pivot-al connecting point 10a. It will be observed that the slot in the hammer is not concentric with the pivotal point 10a and therefore when the hammer swings about said point 10a there is, due to the engagement of the wall or cam portion `of the slot in the hammer with the pivotal member 9, a movement of the point 10a from said pivotal or fulcrum member 9 carried by the frame and this movement is permitted to take place due to the elongated slot in the front sear or lifter 8 which slot permits the sear or lifter to move as a whole.

The spring pressed rod 11 for forcing the hammer forward, after the latter has been released by the front sear or lifter, is provided with an adjustable nut 17 which engages one end of the coiled main spring y 13 and this serves as a means for regulating the compressing force of the spring 13 upon the rod. Carried by slots in the front and

rear handle portions

18 and 19 respectively of the frame and in a manner to permit removal therefrom by a lateral movement is main spring guide bar 14 through which the rod 11 above referred to passes and which also supports one end of the main spring 13. This bar is provided with a hole 15 through which screws for the handle may pass in order to hold the handle in place.

The combined iiring pin and locking bolt 12 comprises the locking bolt 12b and the firing pin 12c both of which are integrally connected and both of which are slidably mounted in the frame 1. The locking bolt 1 2b is so positioned that it is in axial alinement with the cylinder and is constructed so that when the iiring pin is in the position which it must occupy in order to cause the cartridge to explode, the locking bolt will be in an `opening 23a in the cylinder so that the cylinder and frame will be held in proper position relative to each other. The upper rear portion of the combined firing pin and locking bolt is recessed so that the end of the hammer will normally rest therein when not in use.

In `order to hold the cylinder from rotating and also in order to hold the cylinder so that one of the cartridge openings therein is in alinement with the bore of the barrel, there is provided a cylinder stop 25 which is located in sto-p slot hole 26 and which is pivotally mounted upon the frame. This stop is normally held in place by a spring and has an end which enters notches 24 in cylinder 23. A spring pressed latch 22 is slidably mounted in the trigger and is lo-, cated so that a pull upon the trigger will lirst cause a sufficient movement to be imparted, by means yof the latch, to the cylinder stop member to swing the end of the stop member, which is in one of the notches 2li away from the cylinder 23 so as t-o permit the latter to revolve when caused to do so by the hand 20 previously described. Before, however, the trigger has reached the limit of its rearward movement, this latch will become disengaged from the cylinder stop member and the spring will cause the stop member to'return to its normal position when the stop and notched portions are in juxtaposition.

The cylinder retaining means can be clearly seen in Figs. 2, 3 and l. This means comprises a member 29 which is held in normal position by means of the spring 30 and' when in said position abuts against a portion of the frame 30a which prevents the end 29:L thereof from being forced rearwardly. This end 29a overlaps the cylinder 23 but is located to the rear of the end of the cylinder 23 suliiciently to permit said end to be swung forward up out of the way or' the cylinder so that the latter can be withdrawn from the barrel when a rearward movement is imparted thereto.

In F ig. 8 can be seen the specific construction of the cylinder turning hand 20, the sear or lifter 8 and the spiral compression spring 2l therebetween. Integral with the hand 20 is a pin Qtrl which enters openings 7a in the spaced lugs or ears 7b of the trigger 7. Between these ears there is pivoted on the pin 2O1 the sear or lifter 8 which has a portion 8 overlapping the hand 20. The hand and also the'sear or lifter are both rev cessed to receive the ends of the spiral compression spring 2l. It will be apparent that this construction avoids the use of a spring which is hard and diticult to make and utilizes in place thereof a spiral spring which is one of the simplest springs that can be made and it will also be apparent in this construction the spring forces are allied in a very advantageous and simple manner to the hand and also to the sear.

It is obvious that various changes and modiiications may be made without departing from the spirit and scope of our invention.
