'SPECIFICATION forming part of Letters Patent No. 336,289, clated'ebruary 16, 1886.

Application filed June 1'8, 1985. lSerial No. 169,066. -(No model.)

. 5 State of Ohio, have invented certain new andl useful Improvements in Magazine Fire-Arms; and I do vhereby declare the followingto be a l'ull,clear, and exact description of the invention, suchas will enable others skilled in the ro art to which it appertains to make and use` the same, reference being had to' the raccomvpanyilng drawings, and to letters or figures of reference marked thereon, which form a part ot' this specification. y

'I'his invention relates to certain improvements in magazine ire-arms, said improve ments, while applicable to diiferent'constructions of fire-arms, being designed with especial, reference to those desctl'bedand referred 2O to in' lnitcd States Patent No. 285,020, issued the 18th voi"cptcinbei','1S-S3, to William H. Elliot, said arm being known on the market and to the trade as Colts Lightning Sporting-Rifle. A" My present invention consists in certain improvements in the construction of the hammer-locking pawl or lever and the parts cona nected therewith, whereby/thc slide or handle by means of which the breech mechanism is go-,operated can be automatically and, securely 'locked and also unlocked by simply reciprocating saidl slide or handle.

` In the'faccompanying drawings, Figurel represents a vertical longitudinal section of a portion of a breech-loading iire-arnrof the description above referred'to,with the handle y and vbreech locked and the breech mechanism -iufiring position. Fig. 2-represents the position the handle, vlocking-lever, and the ham-` 40 mer assume when the handle is pushed forward andthe breech opened.

In the drawings I have represented an arm such as shown in the patent above referred to; outras `my present invention is confined Ito improvements in the hammer and handle locking lever and the slide connected to the handle, I do not consider it-necessary to give any detailed description herein of those parts not the subject ot my improvements. A represents the receiver, Within whose ward end .the barrel B is-screwed in the usual way.`

for-

aa', one,a,serving as a locking-shoulder tosupb port' the bolt against the recoil of the charge,

the other a' bein@ bored to receive and su -l .port therear end of the magazine-tube I). The projection o" has on .each sidefa lateral projection, b,which serve as recoil-shoulders, to prevent the displacement of the guardst'rap by the'recoil of the charge.

Connected to the forward end of the` strapA E, connected to the operative mechanism, is the handle F, by which the' breech mechanism is operated. This connecting-strap slides in and is supported b'y. groovesinthe guardstrap, and hasy formed on its under face, and between the slots c and d therein, a rectangular or other suitably-shaped notch or recess, G.

H represents the iced pawl and lhandle and hammer locking lever, which is located in the lower part ofthe receiver below the connectingstrap, and has pivotal bearing at e, as shown. rlhis handle and` hammer locking lever has attached toitsunder face a spring,f, the tendency of which is to lforce the forwardend of the locking-lever H upward. The -rear or hammer end of the locking-lever is btn'rcated,

`and is extended rearwardly a sufficient distance beyond the curved or hook-shaped portion K on the lower edge or under side ofthe locking-lever, in order to prevent the pin Lproject-ing from each side of the lower part of thehammer J, passing beyond the rear end of said lever when the hammer is down. The under v face ofthe' rear bifurcated portion of the locking-lever is of curved `or other suitable shape from the hookv or recess K to the extreme end,

whereby when the hammer is sprung', by-pressure upon'the trigger or otherwise, the move' ment rearward ofthe lower portion of"'said hammer causes thc`pin I to press against 4the rear end of the locking-lever and force such 4 rear end 'upward As the flocking-lever has pivotal bearing at e, as before mentioned, it necessarily follows "that as the rear end of the lever is forced upward the front end thereof will be correspondingly depressed. The front end of the locking-lever is provided 4With anupwardly-extending beveled projection, L, in the upper face of which isformed a rectangu- IOO lar or other suitably-shaped 'notch, Mase as to present at thefront ond of thelevera pair of lugs or projections, Land N, the former of l.

which engages the forward `slot in the con'necting-strap, while the latter enga-ges the notch G, the notch 'M in thefront end of the lever engaging with the front walls of the notch G when the handleis in its foremost position,

and thus holding the same and the breech 'and-"theirprojection into a position prevent' i-ng the proper operation thereof. By my improved construction, however, this difficulty 1s avoided, as upon the hammer being cocked as it passes rearwardly the pin I on the lower part of the hammer is forced into the.notched or hookshaped portion G forward ofthe rear end of the locking-lever, whereby thehammer is locked and prevented from passing forward tothe firing-pin. Whilel in thisposition the arbor ofthe `hammer impinges against the rear top edge of the locking-lever and prevents any upward movement thereof. Then the handle is drawn rearwardly to open the breech and secure the extraction ofthe car# tridgelshell, and this accomplished the handle F is pushed forward, which act forces the notch G in the under face of the connectingstrap E into engagement with the notch M in the lower portion of the beveled projecv tion L, thus securely locking the handle and parts connected therewith in position while tiring. Upon these parts being thnslocked the hammer is caused to passforward toward the firing-pin, either Aby pressure upon the trigger or otherwise, and as said hammer moves forward the pin I thereon passes out of the hook or notch vK, and as the hammer strikes-the firing-pin said lpin I passes along the under face of the locking-lever in rear of thehook K, and forces the rear end ofthe lever upward, which act depresses the front end of the locking-lever and unlocks the handle and connecting-strap and permitsof their being retracted to again open the breech and discharge the spent shell.

' g represents a recess in the upper rear face -of the locking-lever H, to permit of the'freeA play of the lower part of the hammer. The operation of the several parts'can be accomplished with great rapidity, the simple reciprocation of the handleF being all that is necessary to secure the automatic'operation ofthe entire breech mechanism, and by my improvements there is no possibility of any of the parts getting out of their proper positions during any part ofthe operations of the arm. Thus there are no slips or breaks in the perfect and continuous action and firing of the arm so long as there is a supply of 7o cartridges.

Having thus described my invention, what I claim is- Y l. In a breech-loading fire-arm, the combination, with a lever or handle for operating the breech mechanism and a hammer having at its low-er portion an outwardly-projecting pin or shoulder, of a strap connected at one end to saidv `pin or shoulder, a pawl or lever having pivotal bearing within' the arm and having near its rear end a notched or hook-shaped portion, the rear end of said pawl or lever extending rearwardly beyond said pinv or shouL.- der and atits frontend having a notched projection, and a handle having a strap or slide provided on its under face with a slot or recess to receivel the notched projection on the forward end of the pawl or lever, substantially as and for the purpose set forth.

8. Ina breech-loading fire-arm, the combination, with a hammer vhaving a pin or projection on its lower portion,- ofa lever having atfits rear portion and on itslnnder face a recessto engage the pin, anda rearwardlyextending portion, and on its upper rear face a recessed or curved portion, and at its front end an upwardly-extending notched lug or projection, and a 'lever or handle for operating the breech mechanism, and a strap connected to said lever and having in its under face a notch or recess to receive the .lower portion o f said notched lng or projection, 'substan tially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
