in 11 vii-om it may concern.

Be it known that I. ruman ammy her. a citizen of the United States. residing at lavetteville. in the county of lVashing- 1 ton and State of Arkansas, have invented certain new and useful improvements in Revolvers; and i do hereby declare the tollowing to he a full. clear. and exactdescription er the invention. such will enable others skilled in the art to which it appertains to make and use the same.

One object of the invention is to insure accuracv of rapid shooting.

Another object is to reduce the strain upon the arm and hand in holding and tiring the revolver.

It is also my aim to form the handle so that it will not only be in position to balance he revolver in such a manner as to insure accurac in shooting but so that it will conform naturally to the hand and will conseturentlv be restful rather than tiresome in the grasp.

.znother object is to provide means for carrying an extra round of cartrid es in the revolver where thev will be accessible for ."liate use in an en'iergency.

iurther object is to reduce the length of the revoivcr over all; compared with the length of the harrcl. whereby the barrel may he .nade longer than in other revolvers without increasing the entire length of the. weapon.

.inothe ohject oi my invention to provide improved and thoroughly reliable locking means for fastening the breaking portionsv of the revolver together. a secondary loch heing cniplovcd to prevent the. acci-L dental opening of the revolver when in use or when handled by an inexperienced person.

further object is to automatically lock the trigger when the revolver is open therein preventing said tri from being pulled the revolver is being loaded. This znridentallv cocking the revolver. while loading. thus preventing accidental dis-;

charge after the weapon has been loaded and closed.

It is also my aim to prevent sparks from flu x 1 7 l MI "I r n in w I 'iw f v v 1 (v1.1a. tron. .arning t..c ingei. liltll I extended along the frame and engaged with the trigger for firing the revolver.

not cause the barrel to waver betlore firing.

notn.er cl eet to improve the constructron and operation of the trigger mechanism wherehvit will be easier to operate and will 3 in addition to raising and releasing the hammer, the trigger is designed to unlock the cylinder. to lock the hammer against accidental discharge, and to operate the mechanism tor revolving the cylinder.

.irnother object of my invention is to provide improved operative connection between the trigger and hammer whereby the hammer and its operating arm cannot become separated or loosened while in the revolver but may be instantly detached or connected when removed from the gun. This connecting device constructed with a view ing back the hammer. as said trigger is pressed back. for automatically tripping said hammer and for returning said hammer when released, as in a hammerless revolver. The hammer is also adapted to be with its retracted position. The trigger is designed to automatically release the hammer when used in this manner.

further object is to provide an improved accidental discharge lock operated by the trigger and serving to prevent the hammer from moving forward a sufiic-ient distance to bring its firing pin into contact with the cap on the cartridge without pressing said trigger.

i till another object is to provide an improved ejector which is simple in construction. reliable and automatic in its operation. The cylinder is retained in position while y the ejector moves back and forth as the t revolver is opened and closed.

Other objects will become apparent from the following description.

1 T he inventionconsists in the features of i construction and combinations of parts hereinai'ter described, illustrated in the accompanving drawings, and specified in the appended claims. a in the accompanying drawings: Figure l a side elevation of my revolver complete K when used for automatic firing. Fig. 2 is an enlarged broken side view of the revolver with the adjacent side plate removed. Fig. is a similar view showing the trigger and hammer in their withdrawn positions just before the latter is released. Fig. 4c is open position to illustrate the operation of the ejector. Fig. 5 is a detailed sectional view on the line c-:r of Fig. 3.

Fig. 9 is a detailed view of the hammer. Fig. 10 a detailed view of the two part connection between the trigger. ham1ner-actuating slide top plan view oi the lock shown in Fig. 13.

Fig. 15 is a sectional view through the fastening device for the upper forward end of the detachable cap. the removal of which converts the revolver from the hanunerlcss to the hannner type. and Fig. 1G is a transverse vertical sectional view through the lock which secures the closure of the eartridge storing chamber in the handle.

Referring more particularly to the drawings, l designates the lower part of the. revolver which carries the firing mechanism. and 2 indicates the upper part including the barrel and cylinder 14. The two parts are hinged together by a pivot pin 5. passed through overlapping pairs of pivot lugs 1 and 2 on the parts 1 and and secured by a small screw see Figs. 1 and 5.

0n the front end of the cylinder there is formed a projecting collar 6 normally engaged by a spring-pressed hook 7 whereby said cylinder is retained in proper longitudinal position with respect to the other parts of the revolver but is free to be rotated for successively lnfinging the cartridges into position for firing. This hook T provided with a small handle or projection for releasing it from the collar (3 when it is desired to remove the cylinder for cleaning the same.

The ejector rod 9 passes through the cylinder in the customary way. The forward end of said rod extends into a chamber 10 in the part 2 of the revolver. Mounted in said chamber. upon the pivot pin 5 as an axis. a segmental gear 11 meshing with a As 3. said segmental gear: has a disk-shaped offset portion 13 arranged This offset porrack 12 on the end of the ejector rod. illustrated in Fig.

between the pivot lugs 2 tion or disk has a channel or groove 1-l formed in its surface W onally thereof. the through its center. said channel or groove are partially closed by flanges 15 which terminate short of the lower lateral edge of said channel leaving openings 16 at each end thereof. In said channel is fitted a lQCiPlOCtltlng pivot pin projecting pivot pin Fig. 12 is an enlarged- The opposite ends of to the elongated slot 18, leaving a resilient I finger 21 which serves to hold the plate inv i i l l l I l l l j l l l l j l g i l l and extending diagplate 1? having an enlarged slot 18 embracing the One end of the plate is made i either of its positions in the channel without en'iploying a separate spring. Projections and 23 are formed on the opposite ends of the plate 17 and are capable of being on tended through the openings 16 at the ends of the channel. The length of the plate, exclusive of its projections, is somewhatless than the distance between the flanges 15 at the ends of the channel so that said plate is capable or having a reciprocating movement. The length of the projections and is such as to bring one of theln flush with the periphery of the offset por tion 13 at one side thereof when the plate at the end of its stroke in the opposite dircction, that is to say. when the opposite end of said plate is in engagement with the cor V responding flange 15. In this position the projection on the last mentioned end of the plate will extend through the corresponding opening 16 beyond the periphery of the disk 13.

The projections 22 and are preferably formed as extensions along the lower lateral edge of the plate 17. The lower sides of said projections are straight. as at 2st, but their upper sides are rounded or beveledras at 27. see Fig. 6. \Vhen. the revolver is closed. the lower projection 22 engages a shoulder 26 on the lower part 1 and the projection is arranged in line with the meet ing edges of said lower part and the upper part 2, but said projection 21) is held within the periphery of the disk 13 by the abutting edges of said lower and upper parts. When the revolver is opened, the projection 22, engaging the shoulder 26, holds the segmental gear 11 rigid upon the lower part as the upper part is swung away from it. The result is that the eject-or rod is moved longitudinally, by reason of the segmental gear acting upon the rack 12, to remove the cartridges from the cylinder. hen the parts 1 and 2 are opened to the fullest extent. the lower face of the upper part, at 27. engages the inclined side of the projection and in riding up itforces the plate 17 upwardlv until said projection is re tracted within the periphery of the disk 13. and the projection is extended. beyond the same along the upper surface of the part 1 at 28. see Fig. el. The projection 23, engaging the iower part, at segmental gear 11 rigid upon said lower part while the upper part is closed upon it. hen the two parts come together in closed position. the lower surface of the upper part. at 29, engages the beveled side of the projection 23 and forces said projection back into the periphery ,of the d sk 13. ex tending the projection 2? into its initial po- 28. holds the sition. The operation of the ejector, is therefore, entirely automatic. The formation of the plate 17 with the resilient finger 21 retains it in either of its two positions until it is moved to the other position in the operation of opening and closing the revolver as just explained.

The handle is arranged below and intermediate of the ends of the revolver, preferably beneath the cylinder. At the top of the front edge of the handle there is a groove 31, separated by a forwardly projecting point 32 from the lower part of the handle, to receive the second finger of the hand when clasped around said handle. The confining of this finger within the groove aids in supporting the revolver in the proper level position in the hand. The arrangement of the handle below the heaviest part of the gun makes it balance more naturally, removing the strain on the hand and causing the barrel to normally lie in a level position when the revolver is in operat-ion. thereby making it comparatively easy to aim the weapon and saving considerable time in firing rapidly, as well as insuring accuracy.

The interior of the handle is hollowed out to form a chamber 33 for the storage of an extra round of cartridges. One side. 34:, of the handle is hinged at 35 and constitutes a closure for the chamber 33. Said closure is provided with a hook shaped lug 36 in its inner face and registering with a recess 37 in the edge of the handle. Said recess extends down to the base of the handle and contains a springpressed catch 38 having a hook 39 at its upper end adapted to automatically interlock with the lug 36 on the closure 3%. The lower end of the catch 38 formed into the shape of a button 40 which is countersunk in the handle, as at 41, space being left to permit the necessary vertical movement of said button for releasing the latch from the lug on the closure when it is desired to open the latter.

The lower part 1 of the revolver is provided with a finger opening or slot 41 located just behind the pivot pin 5 and ejector disk 13. Said finger opening extends parallel to the barrel and into it extends the finger piece 12 on the forward end of the trigger slide 4:3 which also extends parallel to the barrel. Said trigger slide is normally held in its advanced position by a helical spring ll housed therein and abutting against a fixed pin 45 passed through a slot- %6 in said trigger slide for limiting the forward movement thereof, as well as for furnishing an abutment for the spring. The bottom surface of said trigger slide is channeled out at 4:7 leaving a ratchet tooth or projection e8 facing rearwardly and extending down into the plane of said bottom surface. The top surface of the trigger slide is also channeled out at e9, leaving alug extending up into the plane of said top surface. The rear end of said trigger slide has a bifurcation 51 cut vertically and centrally thereof and preferably extending forward to the lug 50, leaving two separated lateral walls at the rear end of said slide. Both of said lateral walls 52 and 53 project above the top of the main portion of the slide. The upper edge 5% of the wall 52 is inclined upwardly and rearwardly from the main upper surface of the slide and the lower rear corner of said wall is rounded at The upper edge 56 of the lateral wall is inclined forwardly and upwardly. Below the trigger slide there is arranged another slide 54' which I have called the hammer-actuating slide. This slide moves parallel to the trigger slide and is nori'nally held in advanced position by a helical spring housed therein and abutting against a fixed pin 59 passed through a horizontal slot (30 in said slide. he rear end of this slide has a vertical bifurcation ('31 formed therein with registering perforations 62 in the sides thereof. Pivotally mounted in said bifurcation. by means of a pivot pin 63 engaging said perforations 62. is what I call a two-part connection between the trigger slide and the hammer. One part ti-t of said connection is pivoted intermediate of its ends in a fork 65 at the forward end of the other part 66. The forward end of the part- 65': is normally held by means of a spring 67, up in the plane of the top of the slide 57,

and is provided with a ratchet tooth 68 facing forward and adapted to engage the ratchet tooth 48 on the bottom of the trigger slide. The rear end of said part G l normally extends below the rear end of the slide 57 and its lower corner is rounded off, as at 69. The part 66 is connected at its rear end to the hammer TO by a safety hinge joint comprising a T-shaped head T1 on the part (36 engaging a transverse slot 72 in the hammer, and the reduced shank 73 of said T- shaped head confined in a recess 'T-t in the lower wall of the slot 72. The opening 75 leading to the slot 72 is of smaller diameter than said slot. This makes it neces; ry for the head 71 to be introduced endwise into said slot. the shank T3, of course. fitting the opening 75. It will thus be seen that when the part 66 is connected with the hammer and assumes its normal position. there is no chance of said parts working loose or becoming separated in the revolver.

The hammer is pivoted at its lower end upon a pin 76. Below said pivot the hammer 15 provided with a forwardly extending The firing pin TS extends through an; opening 111 a rigid rertieal p1rt1t1on S6 arranged t'ansversely of the part 1 of the revolver just r arward ot' the cylinder l. l A, vertically movable hammer locking block 97 is located behind said partition and i:

The othe' portion 95 of said revolving deviceis: mounted 1 teleseopicalli in the free end of the part 93. The end of said telescoping part 95 is 5 formed into a ratchet tooth 9G and below said tooth. said part is beveled oil. as at 97', to conform to the bottom 92 of the slot 1 ated upon i 1 it out- 1 i l.

1 The cylinder 4 is locked in each of its lpositions by a lever 105 intermediatelv pivoted on. a fixed pin 10 and having a lug 107 projecting upwardly from one of its ends into engagement with one of a series iot' notthes 108 in the periphery of the cylinder. These notches are spaced equidistant apart and eor'espond to the ear tridge chambers in the cylinder. The lug it)? is preferably rounded and adapted to ride n a shallow groove 109 between the notches 108. Said lug; 1O?- normally held in engagement with said groove or said notches by a spring 110 bearing upon the other end of the lever 103.

The head 117 of said pin engages the outer face of one of the lateral projections 116. The other end of said pin is bored and tapped to receive a screw 118, the head of which engages the outer surface of the other lateral projection 116 when screwed into the end of the pin 115 whereby said pin is retained in place and the cap 112 is rigidly secured upon the revolver. Said cap is made to exactly tit and conform to the other parts of the revolver so that when it is in place, the joint between them will hardly be discernible and dust and dirt will be excluded from said joint. Then the cap is to be removed, it is only necessary to take out the screw 118 and remove the pin 115, whereupon the hook 113 may be readily disengaged from the lug 11st when the revolver is opened or broken.

is hereinbefore indicated, the hinged part 2 of the revolver is secured in closed position upon the main portion 1 thereof by two locks. The upper lock consists of a springpressed latch 119, see Figs. 13 and 1%, arranged at the rear end of the part 2 so that it projects over the partition 86 on the part 1. Said latch is slidably mounted in a recess 120 in the rigid portion of the part 2 which extends over the cylinder. The rear end of said latch is formed with lateral projections 121 which extend slightly beyond the sides of the revolver and are milled or roughened so as to be readily engaged by the thumb and finger. A vertical passage 12-2 in the latch 119 has a rearwardly projecting ratchet tooth 123 on its front wall. lVhen the revolver is closed, that is the part 2 is closed down upon the part 1, this ratchet tooth 123 snaps into engagementwith a hooked projection or lug 124; on the upper edge of the partition 86, thereby looking the two parts of the revolver together. lVhen it is desired to release the lock, the projections 121 are gripped between the thumb and finger and moved forwardly until the ratchet tooth 123 is disengaged from the hooked lug 12%.

The second or safety lock comprises pivoted member 125 mounted on the main 1 portion 1 of the revolver just in front of the cylinder and above the trigger slide. Said pivoted member is angular in shape, having one arm 126 extending upwardly from the i pivot 127 and the other arm 128 extending forwardly therefrom. The upwardly extending arm has a ratchet hook 129 formed on its forward edge and adapted to engage a similar but inverted hook 130 on the part 2 of the revolver. A spring 131 engages the rear edge of said arm 126 and normally presses the same forward so that the hook 129 will engage the hook 130 when the part- 2 is closed upon the part 1. Milled lateral project-ions 132 extend from the arm 126 of the locking member 125, slightly beyond the sides of the revolver where they may be engaged by the thumb and finger for retracting and disengaging the hook 129 from the hook 1.30. lVhen the revolver is opened, that is when the part 2 is spread away from the part 1, the spring 131 press- .ing against the arm 126 of the locking member 125 causes the other arm 12S thereof to drop down behind a shoulder on the trigger slide, thereby automatically locking said trigger from being pressed while the revolver is in its open position. It will thus be seen that the locking member 125 serves the double function of a safety lock for holding the two parts of the revolver together and also of a safety lock for preventing the rearward movement of the trigger when the revolver is open.

From the foregoing description, it will be seen that, when the revolver is closed and the firing mechanism is in its normal position, as illustrated in Fig. 2-, the trigger slide and hammer-actilating slide are held in their advanced positions by their springs, the hammer is in its advanced. position but held in safety position by the block 97 which is supported in its raised position upon the inclined upper edge of the lateral wall 52 at the rear end of the trigger slide, the cylinder is locked by the lug on the lever 105 engaging one of the notches 10S therein, and the revolving device is in its lowered and retracted position with its rounded lower edge 10 1 resting upon the lower portion of the i clined upper edge 56 of the other lateral wall at the rear end of the trigger slide. It will be observed that when the parts are in this position, the lug on the trigger slide is arranged in front of the i-shaped lug 111 on the bottom of the cylinder locking lever 195, and that the ratchet tooth 18 on said trigger slide is arranged in front of and engaged with the ratchet tooth G8 on the intermediately pivoted part 6% of the two-part connection between the trigger slide and hammer. ll hen the trigger is pressed, moving the trigger slide rearwardly, the hammer-actuating slide is moved with it by reason of the engagement of the ratchet teeth' lS and GS, and the hammer is retracted by reason of the connection 6 between it and said hainmer-actuating slide. As the trigger slide moves rearwardly, the lug 50 engages the lug 111 on the cylinder locking lever 105 and operates to withdraw the lug 10? on said lever from its notch in the cylinder. lVhile the cylinder is being unlocked in this way, the revolving device 93 has been traveling up the inclined edge 56 of the lateral wall on said trigger slide, so that by the time the lug on said lock has been entirely withdrawn from the notch in the cylinder, said revolving device has been raised to the of the hammer connection.

position indicated in dotted lines in Fig. 12 with its end in engagement with one of the ratchet teeth 99 on the end of the cylinder. As the trigger slide travels still farther rearward, the revolving device travels farther up the inclined edge 56 with the result that the cylinder is revolved until the next one of the notches 10S therein is brought into register with the lug 107 on the locking lever 105. In the meantime, the lug 50 on the trigger slide has passed the lug 11 on the bottom of the locking lever 105 and said lever has been returned to normal position by the spring 110 so that the log 10? on said lever engages the notch 108 which has been brought into register therewith and thus locks the cylinder in position for the firing of a cartridge.

All of the operations just described in sequence will have taken place before the trigger slide reaches the limit of its rearward movement. During this operation, however, the hammer has been swung back the requisite distance and the projection 77 on the lower end thereof has been raised into the path of the rear end (39 of the intermediately pivoted part (3% of the two-part connection between the trigger slide and the hammer. As the trigger slide reaches the end of its rear stroke, said lug 77 comes into contact with said rear end (39 of the part (ii and raises it thereby withdrawing and disengaging the ratchet tooth (28 on said part 64 from the ratchet tooth l8 on the trigger slide. The moment these ratchet teeth are disengaged, the spring 58 throws the slide 5? forward bringing the hammer with it and firing the cartridge. When the pressure of the finger is removed from the trigger slide, its spring 1+. moves it forward and returns all of the parts to their initial positions. In doing so, the safety locking block 97 is pushed up between the partition 86 and the lug 79 on the hammer and the cylinder lock is merely withdrawn momentarily from its; notch in the cylinder as the lug 50 on the trigger slide passes under the lug 11.1

the ratchet tooth 68 on the on its lock. As the trigger slide reaches the end of its front stroke, the ratchet tooth l8 thereon snaps into engagement again with the ratchet tooth (38 on the pivoted part (it hen it preferred to operate the re volver as one of the hammer type, instead of a automatically, the cap 112 removed and the hammer withdrawn, by engaging the thumb with the thumb-piece 80, until the, hook 81 on said hammer interlocks with the hook 82 on the springpressed retainer 83. The operations resulting from the reciprocation of the trigger slide, in this case, are the same as already described except that the hammer is released in a different way. The i hammer-actuating slide 57 has been previously withdrawn with the hammer and below the plane of the ratchet tooth 48 on the trigger slide by the engagement of the projection 7'? on the hammer with the rear end of said part 64 in the retracted positions of said hammer and its actuating slide. As the trigger slide reaches the end of its rear stroke, and after its ratchet tooth &S has passed the ratchet tooth (38, the lower rounded corner 55 on the lateral wall 52 at the rear end of said slide engages the beveled forward projection 84 on the lower end of the retainer 83, thereby releasing the hammer which is thereupon immediately drawn forward for firing by the spring of its actuating slide. 1

It is obvious that variations may be made in the details of construction of my revolver, as herein shown and described, without departing from the spirit or sacrificing the advantages of my invention. 1, therefore, reserve the right to make such changes as fairly fall within the scope of the appended claims.

in order to prevent the finger used for pulling the trigger from becoming burned by sparks escaping from the breech of the revolver, I have provided a flange 13% ex tending along the edge of the upper part2 below the barrel and cylinder and above the place cccn pied by the finger when the. gun is m use.
