.ToaZZ whom it may concern:

Be it-known that I, WALTER E. HICKS, af

citizen of the United States, residing at Brooking is a specification. j

My invention has reference. to Vcehtrifugal dynamite-guns; and it consists in providing the same with devices to maintain a solid shot;

an explosive shell, or a combination shot and shell in position at or near the periphery of a' pair of disk-.wheels placed concentrically side by side until, power having been applied-fthe.

required velocity is obtained to throw ordischarge the projectile the requisite distance dcsired, and :the ,details of construction, all of which are fully set forth in the following speciiication, and'shown in the accompanying draw'- ngs; which form part thereof.

agency, revolves the saidlwheels. 4,

Th'e'twin disk-wheels, as' shown i the drawings, Fig. 3, are bulged toward their centers,

their sectional perimeters forming the'curved lines'of a tractory, with cusps cut-off at the axis of motion and asymptotic to the periphery. They' are made in this shape to resist the enor- [nous strain of the centrifugal force, for to thef velocity o'f the wheels is due the accelerationI imparted to the projectile. Near-the periphery of the said twin disk-wheels are four oblong firing-chambers, -F F and F F, Fig. 4r

It is to be understood that two of the firingchambers,F and F, diametrically opposite to each other, are to be unlocked in rapid sequence from the right-hand. side of the twin4 j disk-wheels D D, whilel the two charnbers F and Fhave been unlocked from the 1eft-handl -in order to maintain the stability of the equilibriumof the revolving wheels. vAt oneend the said'firing-chambers-rejournaled in theiis'k'- wheels and rock'. on trunnions h.

' tiens by clutch-hars T, working on shafts'll,

the notched ends meshing with clutch-.teeth T', the other ends of the said clutch-bars being connected to shafts V by rods r and arms c. When the 'projectile is tombe discharged, the shaft V isturned by means tobe hercinafter described, which unclasps the clutch-bars T from theY clutch-teeth Tf, and the chambers F F are throwny upward by centrifugal force and cani U tothe position shown by chambers F F', thcxdoors P falling automatically into pockets dd, as shown by 12 d". Theprojectiles at thi`sinstant having received their acceleration from the velocity of the twin diskwhecls, are released' for their lines of iight,

' and the action of the fring-chamhers dying upward at the moment of discharge counteracts the centripetal tendency of the curvilinear trajectory. Links W, 'attached to chambers F l F and' Ff F and linked to cams U, draw the said chambers down when locking. i

The journals O O, Fig. 3, have circular ilanges a a, with cylindrical sleeves a (d extending on the inside, the opening of which is somewhat large, so ashot to touch the shaltO beyond the 'proper bearings.

On the ends of thesaid sleeves arcthe collars and flanges cc, (set by sct-screws,) and'bctween the said eollarsand flanges and the said journallangcs the disks b I; are placed ecncentrically face to face, revolving on the said sleeves.l vThe said concentric disks are fastened VbyI caps and lhe said caps slide ou the periphery of the journalflanges c a, and by the adjustment of the said concentric disks, so the poiutersZ will indicate on the annular rims ll4 ll the dcgreesof eleva tion or depression desired, and, fastening them there by the caps and th n rub-screws c', the gun canbe discharged-at any given angle in the vertical plane;

Loosely sliding in the Said slecves'nrc thc firing-bolts Z Z,which are held in place by the cross-pins c2 c2,wor ing in slots .in .the sides ofthe said sleeves. On top of the said sleeves are the pawls q whose fulcrnms work in brackets l Z, attached tothe sleeves. Beneath one cndof the said pawls are springs e2 el, pressing upward,so the other ends sink down through holes in the sleeves to catch in notches Z in the firing-bolts Z Z when the said. yiringdoolts are driven forward. Attached to the shaft C are the iring-bars n n.,

. which revolve with the said shaft.

Now, when the' gun is to be ired, the gunner draws the lanyard Y, Fig. 5, which places the lever-arm min the position m. The said lever-arm is'thenstruck by oneof the ri ng-bars ,whiehi 'drives' the firing bolt Z forward through.I the sleeve y. The' firing-bolt Z then strikesrihe'came, driving'it toffv (Dotted "linesUJ .,Thecani o, resting on spring fw, at -tached to ioclbolt m, drives the said. spring and lcckfhelt-to the' positioned and x'. (Dotted lines shown in the drawings, Fig. 5.) The firing-bolt Z next strikes'thc arm g, throwing the said arm and the sectors f and f of the Fig. 1. Sectors f and f having now-'partly revolved shaft V, the arms e, by means of ,conn ectingbars 9:', have unlocked clutch-bars T from clutch-teeth T', and the cam V has raised the firing-chambers F Ff, as shown'in Fig".l 4.'

the lanyard Y is released.
