Application filed May 14, 1927, Serial No. 191,460, and in :Italy ,May .26, 1926.
, The present invent-ion is a weapon based on-anew principles, having the object of throwing at a great distance, projectiles of considerable dimensions and weight, in re- 5 spectbf the weight, dimensions and general w. handi'ness, of the weapon itself. a
lwThe characteristic. features of the present new weapon, are embodied in the-firing barrel, in the projectile and in the standard or 10 carriage.
= In the accompanying-drawlngs is shown,
as illustration 'ofthe principles hereafter disclosed,- a weapon with its pro ecti1e and with its carriage, any alterations in the form orE-dimensions of-the weapon itself or in m the echoiceoftthe most convenient'materials for; its construction being understood -to remain within the scope 'ofpresent invention and appended claims.
-;Fig.-;1 s h0ws a section of the apparatus.
LFigJZ-shoWS a front viewof the-same.

.(Fig. ,5 shows a longitudinal section of the i Sa.,me f., i
=.Fig. 6 shows, to enlarged scale also, a section of the butt end illustrating how the capacityof the explosionchalnber canbe made to vary with the angle of fire.
= Fig. 7. shows in longitudinal section editferent form of execution of the main part of said apparatus with the bomb fitted to it. Fig. 8 shows a viewof the barrel of the same.
vention, is'a hollow body of diiierent shape 5 and dimensions according to its use (see Figs. 1 and. 7).
g t ts rear 18 arranged e ther a ring -g contalmng a number of balls rollersor similar members -71?- movable or fixed (Figs. 1, 4;, and 5) having the object of engaging,
at the start, the external rifling of the firing barrel -a so as to follow its helical development and thus impart to the projectile a spinning action.
A long slender tube d, integral with the i bomb, .is positioned coaxially within said bomb. 7 Sa d tube at has the rear end thereof contracted in diameter as at i (Fig. 1) and 1c0ntains a charge of solid, liquid or gaseous explosive. This charge will hereinafter be called the reaction chargesince it acts tomaintain the initial veloc ty imparted to the projectile by thepropelling charge,
Properly inclined holesfare" drilled around said tube in such a Way. astosend the hot gases issuing at high speedsfrom the same is cut, or applied, a ,ri fling proportioned ..tof the kind of bomb to be, thrown.- .Thisrifling. starts from the butten d. and; derfielopsheli- Cidally r g mth imuaz er i he a r a n d a y-sens; h the spec object of imparting a spinning motion to. the projectile surrounding the; barrel, but helps also to cool the barrel itself. .g
. The internal rlfling, helical cavities-'e cut-in ,the shape 0 turbine blades'which have theobjectof helping, the
projectile to spin by ,utilizing the gases developed by the explosionof. the reaction charge and coming out from ,the inclined holes drilled in tube '-d fixed in the central part of projectile. f saidreaction charge takingfire immediately after the explosion of the'propelling charge.
The propelling charge 13,15 placed within the firing barrel. -a, surrounding the contracted port-ion i of the tube q/, this charge is confined atits ends bythe enlar ementof tube .d-, and breech plug and is ignited by means of firing device -Z of any known type Said reaction chargeis ignited by the gases developed after. ignition lot the pro: pelling charge which enter through the restricted portion .,of the inner tube -d of the, bomb. Thus the reaction charge is ignited immediately. after the ,pro- .pellingcharge and acts from that time until its exhaustion to maintain the-projectileat more orless-the initial velocity.
A different form of execution of above said parts, shoWninFig. 7;besides utilising the pressure of the "propelling charge on'the tube containing the reaction charge .utilizes.
the action of the momentum of. the gases detom of the bomb or ,torpedo,";tl3e firing barrelhaving always, the function of imparting the first impulse and spi-mand (at-creatingthe first part of the trajectory of the bomb and the reaction charge maintaining the function of helpingto obtain 'said spin and to increase .the projectilesthrow. I
In orderto better utilizethe energyfof the propellingcharge 7 without too 'much fatiguing the tube containingthe reaction" charge the "barrels bore is surrounded by a number of longitudinal straight or 'helicoldal holes --a of proper f section,{f somewhat choke-bored at the muzzlefso'thatthegases developed by the explosion'of the-propelling charge contained in; "chamber- M maybe guided "towards the front bottom bf the pro 5 jectile in which are 'ut recesses pro J Said 1 outflowihg -gsges on5 impm against the bombs btlttbiti Ji'nd'f-On' bungee: fiecte'd a certain angle lig'ains'tabove 'said aiianientumyasa g ive the greatest inipi'llsf "at the same timethey start' and; help the seaming was pre'jctilefact l iIlg, a similar waysteamdoes a ainst the blading of a'tui'oini I f" The gases having siient their er against the front Hottom ahdjribs' b'f the' erm jectile exhaustshe atfnd "here through- The abov'describedc'ontr anceisrduce r to its simplest to na ls-essential parts si ns and design may' varg withifi tlie'liriiit ofthe present specification'and appended claims. j Another charact'e'ifisticfeature of the ap paratus is the firing 'de ice ofthe' propelling charge, which consists; '-'applying any breech-loading" ordinary or} magazine rifleblock Z'- of whatsoever typez this will offer besides the advantages-of low cost and easy replacement,that of very quick firing permitted by, such-' me'chani'sm's; once the magazine of said breech-loading block is filled'with proper blank'cartridg'es ther'e re-Y mains but to insert the complete projectile with its propelling charge onthe firing barrel, cock the firing pin and fire as with ordinary rifles. "'j" l r The carriage or frame is built up with two simple angular plates properly riveted to a sheet base plate through: angle irons. Said base plate'is" piv0ted in its} centre on a pipe --2 going; through twoother plates no the lower of-which"-0+ can-be properly bolted on arwobden platforni or frame p so as to be placed eithe'r on' the ground or'ona' carriagefi Said-lower plate carries on its front end ashort-pipe +3 and has an oblong opening rcut out in hip;

. vThe other plate --nwhich is rigid with plates m and can only move parallel to the base-plate o-, is guided by two lateral slides 'tand'may be engaged or disengaged at will so as to allow any kind of.
horizontal shift.
The vertical displacements can be obtained through the pinion o meshing with the toothed sector 'w fixed to the butt-end of' the barrel.
Having now particularly described and as- I ing barrel, a propelling chargein the barrel, a bomb mounted on the barrel, a tube in the bomb, 5 andan additional propelling charge in the tube'which is adapted'to act upon the bomb" after'the initial action ofthe first propelling charge.
2. A bombing apparatus comprising a firing barrel, a'propelling charge in the barrel, external rifling on the barrel; a bomb mount- I edo'n the barrel, a tube-in the bomb, means gy on the bomb for engaging with therifling on the firing barrel, and an additional propelling charge in the tube which is adapted'to 5 act upon the bomb after the initial action of the first prbpelling charge.
3. Abombing apparatus comprising a firing barrel, a propelling charge in the barrel, external rifling-on the barrel, internal rifiing in the barrel, a bomb mounted on the barrel, means on the bomb engaging the external ri'fling on the firing barrel, a tube in the bomb, and an additional propelling charge in the tube-which is' adapted to act upon the bomb after the initial action of the first propelling charge, the gases from said additional propelling. charge reacting against the internal r'ifling of the firing barrel.
" 4. A bombing apparatus as recited in claim 3, together with a carriage for the firing barrel, a pivot on which the carriage is mounted, a base plate provided with a slot in which is inserted the said pivot of the carriage, a fixed standard on the base plate, and elastic means connecting the fixed standardwith the said pivot so as to compensate mounted on the barrel and provided with apertures through which the gases formed during the combustion of the propelling charge may be exhausted into the atmosphere after they pass through the said series of grooves in the bore of the barrel and react upon the bomb, means on the bomb engaging the external rifling on the barrel so as to impart a spinning motion to the bomb, a
10 tube in the bomb, and an additional propelling charge in the tube which is adapted to act upon the bomb after the initial action of the first propelling charge.
