IMPROVEMENT iN BREECHLOADING FlREeRMS.

ASpecifica-tion forniing part ci Letters Eatent No. 53,522, dated Merch 27, 1866.

Tooll whom Ait may w Be it known that I, FRANGXS CLARK, of Auburn, in the county oEWorestcr and State of Massachusetts, have invented certain new a-'iid useful Improvements in 'Brecon-Loading Fire- Arms and I do hereb" declare that the followin g is a full, clear, and exact description of the same, reference being had to theaccompenyiug of this specidation,

y Figure l represents' n sidev'iew of -so :noch ci a breech-loading :tire-erm es is necessary to illustrate my invention. Fig. 2 represents a.

'similiar 4view`with tiiei'ireechfblock turned back, and Figs 3 and 4 representdctached' parts hereinafter to bereierred to.

ln the drcwingen; .represents the breech piece'.` 'ro the' front part, B, the barrel is to be secured,\`vhile thestock isto be secured to the rear, U. The particular-'form of the front and` rear parte, B and U, of the breechvpiece.

Au may be such es will-suit the testes ci' inanuiactnrers. l

The breecirblock D is mede in" two parts, E' and F, 'which parts tney be fastened together by screws a a, or in any otherv proper manner.

Y The breechfbi'ock D tnrnsnpon the-neck G of the ,breech-piece A, and has e screw-thread cnt I uponrthe inner surface ot' its circular part D' 'to iitlnto a scremb, on the neck G. The front end, c, ci' block i) turns upon n shoulder, d, while thel rear end of the' block turns upon shoulder, c.

H is a strap, which is fastened to the under side Vot' the ends B and C to give them greater strength, The circuler vperi: D of block D is in two parts, the pertf being connected withA part F, and the part g with the part E, the

two parts 'meeting at the point h, thus making an expansihle hinge for the block D.

Ai is a stop against which the block strikes,

' and its motion is stopped when in proper position to hold the cartridge in place.

The operation isos follows: Block .O is turned one side, es indicated in Fig. 2, when the cartridge is inserted in the end. of the barrel, which is fastened into the end or piece B. Block D is Fig. 1wi1en its end c is brought close np observed that the block D, when turned inten ally,os shown in Fig. 2, is at the seine tim' drawn back end-wise by the actioirci' screw b on neck G, and when it is turned ba--tk ngnin it is moved forward by the seme means. By this arrangement the rear end of the cartridge is held iirm and secure in place, while 31o l' ioek is not liable to bind so as to prever-1 it xroln being readily exploded shell.

pand readily, being open jat h, and consequently is not liable to bind by the heating of the parts so as to interfere with the proper action of the whole when in use. By making the block l) iu two parts I am able to make the parts B, C, and G all in one piece, which for many ree-v s'ons is advantageous.

The application .ot-the'1ock, the mode of firing or exploding the charge, and removing the exploded'shell being substantially vthe s same as described in patents previnsly granted to me, no extended description of such mode of operation is here deemed necessary, since my present invention relates to the mode of construction and operation of block D and the parts connected therewith. YHavingdescribed inyimprovemeutin breechloeding rlire-arms, what; lcleim therein as of my invention, and desirel to secure by Letters Patent, is

1. Making block D in 'two parts, substantially as set forth.

2. Making the circular part D' open,as at k, as and for the purposes set forth.

3. The combination of the parte E and F,

jects past the end of F, and prevents any joint in the block where it comes in contact with the rearof the cartridge.
