IMPROVEMENT IN REVOLVING CANNONS.

Specification forming part of Letters Patent N0. l 10,191, dated December 2.0, 1870.

To 4all whom 'it may concern! Be it known that I, EDUARD BREHM, of Jersey City, in the county of Hudson and State of'NeW Jersey, haveinvented a new and Improved Revolving Gannon; and I do hereby Vdeclare that the following is a full, clear, and

exact description thereofwhich will enable others skilled in the art to make and use the same, reference being had to the accompany- 'ing drawings, forming part of this specification, in which- Figu're 1 represents a vertical longitudinal` section of my improved revolving` cannon, mi', Fig. 2, being the section-line. Fig. 2 is a vertical transverse section of the same, y y, Fig. 1, being the section-line. Fig. 3 is a horizontal section of the same, z ve, Fig. 2,- beiug the .section-line.

Similar letters of reference indicate corresponding parts.

My invention relates to a revolving cannon for rapid ring, and my purpose is to improve thereon, as hereinafter described, and subse- `guently specified in the claim.

A in the drawings representsthe frame in which the cannon-body B is hung, by means of trunnions a a, in the well-known manner. The

frame A terminates at its lower end in a turn table or plate, which is, by a swivel-bolt, b, pivoted to the stationary or supportin g frame U. A worm, c, hung in, the frame C, and

meshing into the toothed edge ofthe turn-plate of A, serves to set the cannoli horizontally, so as to point it in any desired direction. A vertical screw, d, arranged in the frame A, behind the trunnions, supports the breech end ofthe cannon, and serves to adjust the range of the same.

The cannon-body I3 consists of the front barrel and of the breech-chamber D. This breechchamber is enlarged downwardly and to the each set containing as many separate receptacles ff for cartridges as there are bores or clef receives one cartridge, and is, by a backwardly-extending tine perforation, connected with a groove or chamber, g. The groove or chamber g is in communication with ai nipple, h, which projects from the disk E, there being one nipple k for each of the sets ot` cartridgechambers. Whenever a percussion-cap onone ot' the nipples is exploded it will ignite the powder in the groove or chamber g, and thereby also all the cartridges of the set to which it pertains. Whenthe disk is so turned that the several cartridge-receptacles of one set are in exact line with the bores e, and when then these cartridges are exploded, as aforesaid,

their charges will all be passed through and directed by the said bores Qr barrels e. The disk can then be turned to bring another set of cartridges into line and have the same discharged. The turning of the disk is effected by means of the shaft F, which has a crank-handle, z', to be turned. The shaft can be readily withdrawn to release the disk and permit its removal and the insertion of another. The shaft has a projecting lug,'j, which, entering a notch in the disk, serves to carry the same round with the shaft. A forked key, k, Iitting over the grooved frontend of the shaft. serves to retain the same in position for op ration.

The hammer G, for exploding the charges,'is

secured to a spring, H, and is raised by the cam-shaped edge ofthe disk between the nipples. When a nipple arrives under the hammer the latter is suddenly forced down upon the same -t0 explode the percussion cap, and to lock the disk in the proper position for the discharge.

The bores of the barrel B diverge from their breech ends in a horizontal direction, as is clearly shown in Fig. 3, so that they will serve to spread the shot and to sweep an extensive expanse of ground. A

The grooves or chambers gare protected by removable plates l, which are held in place by means of screws or other fastenings. When these plates are taken ott the said grooves or chambers can be properly cleaned or filled.

It is designed to take to a ticld of operations a series of disks, E, properly loaded, and to rapidly replace each one when discharged by one that is still loaded, and to reload those which are emptied while the others are being Each receptai discharged, so as thereby to be able to keep up an absolutely irresistible ne againstan approaching enemy.

A suitable armor, made of sheet. metal oxother material, can be applied to the frame of the cannon for protecting' the men attending to the loading and operation of the same.

Having tbusdeseribed my invention, I claim as new and desire to secure by Letters Patent- A disk, E, having a cam-shaped edge, and

several sin gle-nippled sets of cartridge-holders, combined, as desnribcd, with n-spring-halnmer, G,\vbiob antonmtcally looks the said disk and explodes tliecnrtridges in the manner set; forth.

EDUARD BREIIM.
