Specification foriningpart of Letters Patent No. llg?, dated August l, 19:76; application liled June 1, 1876.

To all whom if may concern:

Be it known that I, FRANK W. FREUND,

of Cheyenne, in the county of Laramie, in

the said gun as it appears inst before tiring.

Fig. 55 is e. similar section of the said gun as it appears during the act of loading. Fig. 4 is a vertical longitudinal section through the retrnctor of the cartridge-shell, .showing` the rctracting-head at its extreme distance from the gun-breech. Figs. 5, 89, l() are def tailed views oi' my improved breech-block, hereafter fully deseribed.- Fig. 7 is a perspective view ot' the firing-pin slide block. Fig. llis a perspective view ofthe retraotor. Fig. l2 is a top view of my gun, with the breech closed; and Fig. 13 is a top view of the same, with the breech open.

rl`he nature of my invention consists in certain constructions, combinations, and arrangef ments of parts, as hereafter described and speciiically claimed, whereby an improved breech-loading gun is produced at a very slight cost.

The chief ohiect of my invention is to make e breech-block for a breech-loading gun, which cannot be moved beyond the limitof its ascent, and which stands at a right angle to the center of the gun-barrel, and which, in its descent, gradually swings around its horizontal axis, with its top olf the breech to slierten its downstroke, and to operate the retractor, and which in its ascent gradually, and with ease, pushes the fresh cartridge into its proper position.

To enable others skilled in the art to under stand my invention, I will proceed to describe it.

In the accompanying drawings, A represents a guirbarrel, and I3 the breech-frame, to which it is fastened; G, the rear stock; 1)..thc humilier, and E thc sight, all constructed in the manner as generallyr adopted. The breechspace F, in which the' breech-block G is oper ated, is provided with guidestrips g 'right and left of the breech end (t of the gun-barrel, which breech end is made to project beyond the front wall of the space F to avoid unnecessary friction ofthe breecl1-block in the mortise of the breech-frame. The rear side of the breech-block G is provided with an inclined offset, gl, whereby the parallel top part of the breech -block is reduced in thickness. lhe mortise of the breech-frame has a correspond` ing ol'set, I), against which the otl'set ot' the breech-block rests in its normal position. The remaining sides of the breech-block and niortise are all vertical land parallel, so that when the breech is closed there is a perfect iit between the' breech-block, the guide-strips g, the breech end aof the gun-barrel, the sides, and the rear abutment ofthe mortise. The move ment of the breeclrbloclt G is el'ected by the trigger-guard I-l, whichis. pivoted at It to the breechvframe, and is connected by means of the eccentric pin h1, the link I, and, pin 'i to the breech-block, which, for the reception and easy operation ofthe said link is slotted be low the level of the bore of the gun. The pin It serves also as a pivot for the reti-actor J, as seen in Fig.4, which, in its normal position, stands between the breech-block and the fore end of the mortise in the breech-frame aside from the breech end ay ot' the barrel A. The rctiecting-arm j is inserted into the metal of the breech end a in 'the usual mode, and may form a horizontal or other extension ot' the same. A lcver,jl, extends from the retractor toward the rear into aslot, g2, in the b1eecli-bloch, the end ot' which serves to throw the retractor backward, when the breech-block is moved down, as Fig. 4 shows.

An eccentric check, j", serves to limitl the back swing of the retractor by coming 1n contact with the lower end b ot' the breecl1-l'1anie. The descent ci' the breech-block G is vertical until its parallel top part connes to the offset b, when by means ot' a curved slot, f/i, in the side of the breech-block, (shown in Fig. 8,) and a rigid guide-pin, b2, in the side of the inortise, (shown in Fig. 13,) the said breech-block bccomes lifted with its top to the rear, which movement is steadicd by a lug, b, below the rear end ofthe mortise. A straight guide 'ueegeee 3 no chance for swayor other movement, and the swinging movement ot' my breech-block is necessarily connected with a vertical movement, which is not the case in old constructions.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, iS

1." [n a breech-loading fire-arm, a; breechblock, having a reduced upper part and parallei front and back sides, the upper and lower parts having a connecting-surface adapted to wedge the said breecli-block firmly intel-its normal position, substantially as described.

V2. In a breech-loading tire-arm, a breechblock, which moved verticall 'y into or out of the range of explosion, and in a curved direction and inclined position beyond the said range, by mechanism substantially asdescribed.

3. The breech-block G, having an inclined offset, g1, and a lvertically-mortised breechframe, B, having a correspoudinginclined oiset', b, constructed and operating substantially as set forth. J

et. The retractor J, having a retraeting arm orwing, j, a lever, jl, and an eccentric check, f2, constructed andv operating substantially as se't forth. y

5. rlhe combination of the breech-block G, having au inclined groove, g5, and being rounded at the -top,Jthe spring K, the trigger-guard H, land the link I, whereby the cartridge may be forced over the said breech-block into the gun-barrel, and whereby the cartridge is prevented from falling accidentally oc of the gunbarrel before the breech is closed, substantially as set forth.

A6. Thecombinatiou of the breech-block G, having a groove, g3, and the breech-frame B, having a guide pin or lug, b2, substantially as and for the purpose set forth.

7. The combination ot' the breechblock G, the spring K, and the trigger-guard H, havin g a horizontal surface, h2, a friction-roller, h3, and a check or heel, h4, substantially as and for the purpose set forth.v

8. The combination ot' theoreech-block G, having a vguideW-ay, g, andthe breech-frame B, having a lugg'l, substantially -as and for the purpose set forth.

`9. rIhe gas-trap Z2, formed partly on the rib Z of the sliding block L, and partly in the bottom of the groove g6 in the breech-block G, substantially as set forth. f 'j Vitness my hand in matter. of my application for a patent for improved breech-block' for tire-arms.
