' TU (Ill whom,- it may concern:
Be it known thatI, CHARLES M. BROWN, a citizen of the United States, residing at Chicago, in the county of'Cook andState' of Illinois, have invented certain new and useful Improvements in Projectiles, of which the following is'a specification. L
The present invention relates to that class of projectiles that are p'rovided witha vane or tailpiece adapted to control the position of the projectile during its flight and compel jectile, the partsbeing shown in the posi tions that they occupy during the flight of theprojectile. Fig. 3 is a section on the line 3 3, Fig. 1. Fig. 4 is an elevation o f the rear end of the projectile. f r
A represents the body of' 'tho projectile; whichin the illustration which Iha'v e selected for the pni'posesof the present application is in the form of ahollow shellh'a'ving af cha 'na be'r Bfor containing anexpl'osive charge; The rear "end of this chamberis closed by a screw-ping *0 having a1 centrally-located threaded opening OTfor receiving the inset. This ping also providcsthe ncansfor atta'ch ing the vane or tailpiece nat on ccording to the-present invention consists of'a r nger a diskhavinga central opening d, register ing with the fn'se-opening C or the? ing I The plug is provided with'a'plurality of eqiii distant sockets E,'\vhieh projectin war s con he plug-properv and are "adapted macaw the" siderable' distance past the inner end; 0'
enlarged heads f of the stems F; by whichth vane or tailpiece'is. carried; The" object the prolongation of the'so'cketsE isto n'able the use of' stemsof the lon'gth necessaryjin order to per-mittheitailpieceto move a saidcient distance away from the rear end of the projectile. The inner end of each of the 2 manner .dese
sockets E is closed by a screw-plug e. The plug C has a flange 0, which bearsagainst the rear end of the body'proper, andt-this flange is reduced for the purpose of allowing the air" to impinge against the, margin of the vane or tailpiece during. the flight of the projecti'le,"and thnsmove'the vane' or tailpiece ifro'inits position against the; rear end of the projectile, as shown in- Fig. 11; to its position some distance in rear thereof, asshown in Fig. 2. k The margin of the vane or tailpiece is also chamfei ed on the forward side. Asa
result of this theair impinging open the slopingportionof the vane is deflected outward, and thereby tends to more.certainly'hold the vane in eorrectposition at the rear of the projec'tile. It isthonght that by snllicientlyre- 'dncing the-projectile in the vieinityol' the vane" or tailpiec'efthe action of the air will be snfflient'to displace the vane or tailpiece in the manner described. 'l ha' i 'e not, however,
verified this by tests, and while reserving to myself the right to use this means alone for displacingflthe v'ane or tailpiece,,shonld it prove to beefllcient to this end, still I have.
sho 'i l g jnwings an additional means "by whichtlievane or tailpiece will with certaintybejdisplaced. This additional means consists of one or more chambers G, formed in th'el rjear endof the plug 0 and filled with a slo'wrbnrning explosive substance; the vane or tailpiece beingprovided opposite each oi :said chambers was an opening d; I The heat prfodncedby the ex'plosionof the projecting chargeignitesfathe charge in the chambers G gthro'ngh thejopenings d, and by reason of the character of theexplosive' in these chambers rea lepmplete explosion='w'ill not take place n'ntil'fa'fter th'e-proj'efc'tin g force d no to the ex-. plosion of'thef projecting charge has ceased was ripen the vane ortailpiece. IJThis ren a nij s men o'ded porti'oii of the charges 5 in the ha-Inl)e 's, G will then in exploding 11 1793 6 3 A H j or tailpiece" round the margins of) the openhaek ardpressnre upon ,the vane 6;; wh le are smaller than. the I openings ejchanibe Ggand-ldisplaeeit in the d" P eierably 1 use a plurality of these chambers; G; and dispose them at eqnaldistanec's apart in oi'der'to preserve the balanced condition of the projectile. .It is for this reason also that I prefer to use. a
vane o'r tailpiece of the annular form shown, which form enables the use of a centrallydisposed fuse. I
In order to hold the vane or tailpiece in po= 5 sition against the rear end of the projectile and prevent it from moving away therefrom in the ordinary handling of theprojectile, I
unite the ad acent faces of the'vane or tail-- piece and projectile by some holding means,
by the heat developed inthe-explosion of the projecting charge. To this end I prefer to inter-pose between said surfaces an adhesive gasket H, made of or containing an adhesive" cement 'or a thin film of soft solder which will melt readily by the heat developed.
i Ihave shown and described the several features of my invention asbcing embodied in "a. hollow shell; but manifestly features are not limited to shells of this class.
-- Iain. aware that it -hasf ,been proposed to provide a projectile with a vane 01' rtailpiecc consisting of a continuous disk which is practically equal in diameter with the diameter of the'plug for closing the rear endof-the projectile, the margin of the-plug in the'immediate vicinity of the Value or tailpiece being gradually contracted. This contraction of the plug is-not theiequivalent of chaptering the vane or tailpiece, nor is'a vane or 4 tailpiece consisting ofthe continuous disk .cnigents of airstriking the chainfered sur-f 5 face-will be deflected outWarrL'soythat so long as these-currents remain equal .on-a'll sides of the vane or tailpiece they will tend to hold the projectile to-itsco'urse butshould the projectile from any can so be swerved from a position-strictly in line with its trajectory then the cha'mfered surface on one side of I the vane or tailpiece will be-brought to a positionmore-nearty perpendicular. to "the. line.
of'resistance, while the chamfered surface on 5 5 the opposite side of the vane or tailpiece will with-this line. The advantage of a vane or tailpiece having an opening is that the opehin'g aifords an exit for the air which enters; the space between the-vane or tailpiece and the body. Without any opening in the rape or tailpiece the air would be compelled to both enter and leave this space at the peripheryof the vane or tailpiece, and this would result in more or less inequality injthe distributionpf the pressure.
Having described my invention, what I the holding power of which will be destroyed.
