GUN WETHBAEEEL ADJUSTABLE 1N A LATERAL DIRECTION.

Specification of Letters Batent. Patented July 19,1921..

Application filed September 4, 1920. Serial vNo. 408,386.

To @ZZ whom t may concern:

Be it known that LEOPOLD SCHMIDT, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Guns withV Barrelsfidjustable in a Lateral Direction,

(tor which l have tiled' application in Germany, filed March 9, 1918,) of which the following is a specification.

This invention relates to gun carriages,-

with a gun barrel which is adjustable in a lateral direction and with a traversing gear with two operating members which are 1n.

dependent of each other, and of which'the one serves for the lateral adjustment of the v sighting line, while the other` is intended without iniiuencing the traverse imparted to the sighting line by the first operatingr member, to vary the angle which the planes passing' through the sighting line and the longitudinal axis of the gun carriage .at right angles to the bearing plane of the gun carriage form. vThe present invention relates to. a construction of a gun or' this kind, which also insures an accurate lateral adjustment oi' the gun when targets have to be dealt with, which, like aircraft for exy ample, are situated at a considerable height A rected upon the point of impactitself (d) above the place where the'gnn is situated.A

The invention will be firstly described with the aid of diagram shown at Figure l ot the drawin "s the remainino- Figs. 2 to 6 g 3 b b inclusive showing an example of construe#v tion, being hereafter dealt with.

ln Fig. Vl let a denote the place where the gun is situated and bthe path along with point Z by 21. By observing the movement ot' the target the angle may be determined without difliculty which the line of vision toward the target describes in the unit of time.

if the range of the target at the moment be ascertained, say, by means of a rangeA 'inder and also the corresponding Hight of the projectile the angle 8 is thereby determined, which the straight lines a c and a fl' iorin. At the kinstant of firing the shot the time of flight oi the ci the` gun barrel dinal axis of gun is so adjusted, that the :sighting line co incides with the straight line a c and therefore the vertical plane passing through the sighting' line coincides with the plane a c `01. Et the target were stationary,` and if the' dritt of the projectilel and ythe'influence of the wind were ignored, the vertical `plane*` passing through the longitudinal axis of the@ gun barrel would also have to coincide with the plane a c c1. v As, however, during the' projectile the target has inoved `toward the point d, the gun must` be so adjusted that the vertical plane pass# ing through the longitudinal axis of :the gun.L barrel may? coincide with the plane a (Z df. The vertical planes passing through' the sighting line and the longitudinal axis Y A Y must` also describe an angle 'which isequal to the angle between the planes a c c1 and d d1. This angle is; equal to the angle lwhichV the straight lines a o1 and a d1 form, that sto say, is equal to en r theprojection of the angleV 8 on the plane a c all. v

Hitherto it has been assumed that the target is movable. The same conditions exist however in thev case of a stationary target if the sighting line ofthev gun cannot vbe dijusting the sighting line of the target tothe Y angle which is tofbe regarded as given, the j vertical planepassing-through the longitu'V gun barrel is automaticallyv adjusted to the angle (81) and moreover in such a way that the sighting line in'thiscase can permanently retain the direction toward the target. i

The. invention will be further described with reference to the accompanying drawings jn which Figs. 2 to .6 show aV construction of gun according to the presentA in. vention.

Fig. 2 being a. side elevation of the gun,

Fig. 3 is a-sectio-n on the line 3-3 of'Fig. 2, lookingfrom the left,

Fig. 4 isa section on the line of Fig.

3, on a larger scale, looking from above,

Fig. 5 is a top plan viewo'f the part .of

the gun .denoted by'lthe arrow m in Fig.A

tor elevating gear B2.l The gun carriageCV can be rotated on a pedestal D by means of being rotated a pin C1, the Vgun carriage 1 at right angles aboutthe axis Vof the -pin to its bearing plane by means of a travers-` ing gear with a-worm E, which is mounted on a shaft E1, which is mounted in one of the side wallsjofy the gun carriage and lcar-v ries a hand wheel e2 and engages with worm teeth Z1 attached to the pedestal D.

On one' of the two trunnions b1 which is located on the same sideas theV shaft El, is rigidly fixed a rocking lever 63', which is coupled by two parallel connecting rods F to a second rocking lever G rotating about a similarly directed axis. This Vsecond' rockinglever G is rigidly Ymounted on a shaft G1 (see Fig. 3) which is mounted in a sleeve c2 carried on the gun carriage. vThe sleeve c2 widens out on the side remote: from Vthe wall of the gun carriage into a drum-shaped hollow-pin03, to which is attached in the center a continuation c4, vwhich 'terminates in a solid pin c5. Y@n the hollow pin c3, the axis of whichcoincides with the axis of the shaft G1 and VVthe lcontinuation c4 is rotatably mounted a composite sleeve H provided Ywith a spherical shaped intermediate piece h1,

and reaching almost tothe-free end of vthe pin 05. e i

Upon the intermediate piece tl isl Afixed by means of'two coaxialVA pins 'il the axis of which cuts the axis of rotation of the sleevel hand wheel 7:1 (see Figs. 2 andV 6), which gears into a ring of'teeth 06. on the hollowv pin c3. By rotating theY hand wheel '7st the Y sleeve H can therefore be so rotatedon the arm formed by the sleeve czthe hollow pin c3 and the continuation c4 .togetherwith the pin 0 5, that the sighting line of the sighting telescope J2 receives the Ydirection corresponding to thev elevation of the target. The sleeve H forms therefore the carrier for the means of determining'the elevation of the sighting line.

For reading oill the range of the target there is provided in the part of the sleeve H, which covers over the 1 hollow pin c5, a

through aperture provided with a reading off edge 7b3 (see Fig. 5) and through which a range graduation g3 is rendered visible. rlhis latter is arranged on the outer surface of a sector G2, which is rigidly mountedon the free end of the shaft G1 coupled to one of the trunnions (1) and projecting into the hollow pin c3, and projects into a recess c7 (see Fig. 3) in the hollow pin in such away that its outer surface, which carries the graduation g3 lies flush with the outer surface of the hollow pin.

The ring J, which can be'rotated relatively to the sleeve H about the axis of the pin il, formsthe'carrier of the'sighting means of the sighting device, which determines the traverse of the sighting line. The traverse is-adjusted by means ofy an annular operating member M, which Vis rotatably Vmounted inside the part 71,1 of the sleeve H on the continuation c4 by means of a nonrotatable pin 08 connected thereto. The axis lof this pin 08 passes through the point o and is parallel with the Vaxis of rotation ofthe gun carriage C, which coincides with the axis of the pin C1.

T he operating member M has a cylindrical `Vexternal surface mi, the axisV of which like-V wise passes through the Vpoint 0 and it further lias two flangesm2 arranged at right angles thereto. OnA the ring J are rotatably mounted two coaxial pins N, the common axis of which likewise passes through the point 0 and is parallel with thesighting line of the telescope J2. The pins N- project through an aperture 71,4 in the part tl of the sleeve H into the interior of the sleeve and are embraced on their free ends by sliding pieces P, Vwhich are guided between the iianges m2 on the outer surface m1 of the operating body M. The axis ofthe pins N is .therefore guided inthe central'plane of the operating member passing through the axis of the pinos at right angles to the axis of the cylindrical outer surface m1, which will be briefly termed hereinafter the guiding plane. In consequence thereof for every angular position, which the sleeve H can assume relatively to arms ,c2 c3 c4 c5, a rotation of the operating member M about the axis of the pin 0S must cause a rotation of the ring J relatively to the sleeve H about the axis of the pin 1.

The valve of Vthe'angle of rotation of the ring J is thus proportioned in accordance with the angular position in which the sleeve H is situated relatively to the arms c2 c3 c4 c, that is to say, according to the inclination of the sighting line ofthe telescope J 2, said value is different from the value of the angle of rotation of the operating, member M.

One ofthe twopins N is rigidly` connected Yat its outer end to a graduated disk N1 and providedl with a series of bevel wheel teeth n2 which gear with a series of teeth provided on the `edge of the corresponding aperture h4. Rotation of the ring J about the axis of the pin 1 therefore causes a rotation of the graduated disk N1 relatively tol the ring J and the angle of rotation of the graduated disk N1 is proportionall equal to the angle of rotation of the ring d.

The value of the last mentioned angle of rotation, by which the amount of traverse to be imparted to the sighting telescope J is measured, can therefore be read off on a graduation n3 (see Fig. 2) arranged on the graduated disk N1 by means of a mark (not shown in the drawingJ) on a rib 3 (see F'gs. 2 and 6) on the ring If theoperating member M be so adjusted, that the guid-` ing rplane determined thereby is at right angles to the axis of rotation of the sleeveA H, the mark located on the rib i3 points to the zero point of the graduations n3, irrespective of the angular position whichthe sleeve H assumes relatively to the arms c2 c3 c4 05. e

The p operating member is moved by a worm gear, which consists of a toothed sector m3 rigidly connected to the operating member and a worm Q gearing into the said sector and mounted on a shaft Q1 carried on,

the continuation 01. On this` shaft :Q1 is mounted a bevel wheel g2 (see Fig. 4). This bevel wheel gears with a ring of vteeth r1,

which is arranged on a sleeve R, which is,

surrounded by the sleeve H and canrotate independently thereof about the same axis'. The sleeve R has a member R2 rigidly connected thereto in which are carried'two bevell wheels S; situated opposite each other and rotatable aboutl the same axis, so that their axis of rotation cuts the axis of rotation of the sleeve R (which coincideswith the axis ofthe pin c5) at right angles.

In the member R2 are also mounted two bevel wheels TandU. locatedA opposite each other, the axes of rotation of which coincide with the axis of rotation of the sleeve R and each of which engages with the'two bevel wheels S. `Rigidly connected to the bevel wheel v'1" is a milled head T1and to the bevel wheelv U a spur'wheel U1 and which spur wheel U1 engages with a toothed wheel La?,

which is fixed on a shaft V which is mountedon the continuation c4 and extends into the sleeve c2.

gears with a bevel wheel w1, which is mounted on one end of a shaft W carriedV on the .i

sleeve c2 and the corresponding side wall of the gun carriage C. 0n its other end has been p above stated, there is provided for the l'operation On its end lying inside the sleeve 01, the shaft V carries a bevel wheel lo? V(seeFigs. 3 and 6)v which bevel wheel l'v2 of the operating member M a traversing ing members, which are independent of each other, namely, the handrwheel T1 and the. hand wheel e? (see Fig. 'Then when on thevone hand the hand wheel c? is at rest, the bevel wheelfU on the" gun carriage C is also at rest as this wheel is positively connected Y Y tive rotation .of the sleeve'R andofthe op v erating member M, which is always positively connected thereto by the gearings r1, Q2 and Q, m3# On the other hand, when ythe handwheel` T1 and consequently the bevel wheel T is held fast, a rotation vof the hand wheel e2 effects naddition to a rotation ofi the gun' carriage aboutthe axisof the pin C1, a rotaf tion of the bevel wheel U positively connect ed to the rhand wheel e? and consequently by means of the returning Asun and planetY gear U S T VR?, of which the middle wheel T is now fixed, again apositive rotation ,of the sleeve R fand of the operatingrmember M, which is alwayspositively connected t0 it. The conditions are so selected in this case. that the operating member hf is rotated relatively to the continuation 04 andrconse-V quently also-.relatively to the ygun carriage always through the same angle but in the opposite vdirection to that inwhich thegun carriage is rotated relatively to the pedestal. The guide plane fixed at the operating member retains therefore, onrthe rotation of the gun carriage, always the. same direction relatively `to thefpedestal D. lThe adjust-V the drawing; the guideplane ofthe operat:

ingfinemberan'd the sightingpline of thek telescope JZ, Iwhich is always parallel withV it are therefore in this adjustment parallel with the p-lane passing at right angles .to` the4 axis of thetrunnions .through the longitudinal axis of the gun barrel. .The readingo-ff@ mark arranged on the rib "i3 then always points to the zero point ofthegraduatio-n irrespective of which angular position the.

sleeve Hfassumes with respect tothe arms-V Y c a Y 13.0

In order to impart the rough traverse to the gun, No. l of the crew turns the hand wheel T1 andthe No. 2 the hand wheel 62 (see Figg). In order that this may be more Veasily understood let it be first as-v sumed 'that the rotation of both the hand wheels does not take placev simultaneously but the one after thevother.V The rotation of theV hand wheel T1 alone results, as lex-V plained more fully above, in the operating member M rotating relatively'Y to the gun carriage C and, as this latter islprovisionally stationar relatively to thev'pedestal' also. The rotation of the member M is transmitted by Vmeans of the sliding pieces P andthe pins N to the ring J Vin'such aV way, that this latter'rotates about the axis of the pins l relatively to the sleeve H, and

the sighting line lof the telescope J 2 fixedson the ring J will therefore likewise be traversed both relatively to the guncarriage and the pedestal D in a lateralfdirection.

`lVhen the ring J rotates, the bevelwheel teeth a2 on the pin N rigidly connected to the graduated disk N1V travel-overthe teeth h5 so that the graduated disk i 1 is rotated relatively to the ring J. The reading off mark arranged onY the rib'z'gtherefore, after the sighting line'has been traversed by a certain amount, no longer points: tothe Zero point of the graduation n3. It is'now as'- sume'd that No; 2 ofthe crew turnsthe hand wheel e2, while No. l holds the hand wheel T1 fast in the angular position, which thisV wheel has just arrived in. I The rotation of the hand wheel@2 alone effects as more fully explained above, on the one hand by means of theV worm gear ELcZl, a rotation of thel Yofun carriage C about the axis of the .piniv C1 and onthe other hand b. means oi' the driving gear El @3, 102 Wr w1, 2 Vo1,'U1,U, S,

T, R2 R 75g? Q1, Q, m3 a rotation of the*V operating member M relatively to the conf tinuation c? about the axis of Vthe pin 08; Connected with this rotation of the operating member M, there is again va rotation of the ringJ 'about the axis of the vpin 1' and consequently rotation of the' graduated disk relatively tothe ringAJ. The rotation of the hand wheel e2 may take place suoliv a direction that the zero point of the gradu-V ation on the graduated diskllL approaches Y the reading off -mark on the; rib 3 (see VFigs.

2 and 6) andthe rotation is continued'until the zero point agai'n coincides with the zero mark.

The guide plane fixed by the operating,

member M and the sighting line of the Sighting telescope J 2, which is always parallel therewith, are then againat right angles to the axis of rotation of the sleeve H parallel' with the axis of thetrunnions, that isv to` say, the plane passing through the longitudinal axis of the guny barrel at right angles to the axis of the trunnions,'is again 153853153ikv parallel with the guide plane of the operating member'lvi'an'dthe sighting line.

No alteration is made in the traverse, which was imparted to the guide plane of the operating member M and the sighting line of the telescope J 2 always parallel to this plane, relatively "to the pedestal D of the gun bythe rotation oiilthe hand wheel e2 since, as above described, the gun carriage rotates Vwith the operating member inthe opposite directionthroughthe same angle. The result'V of the two successively eiiccted-v rotations of the hand wheels T1 and e2 consists Vtherefore in the fact that the sighting line? and the gun 'carriage' C fare traversed without alteration of their mutual angular position conjointly through a definite angle Vin a lateral direction.

,The same resultV is of course attained, when the two -hand whe'els'l1 and c2 are rotated Vsimultaneously and .the member of the guns crew, who rotates the hand wheel e2, observes that the reading oii2 mark on the rib i3 always points to the zero point of the'graduation n3. simultaneously' rotating the Vhand wheels T1 and e2 any desired traverse can be impartedl to` the sighting.,T line and the gun carriage Vconjointly with? out alteration of the mutual angular position. Y i

' Afterlthe rough traverse has been impart'- ed in the manner described, No. l of ther guns crew now rotating'the hand wheel T1v and thev hand wheel 701 simultaneously (sce Figs. 2 and) and consequently by means of the worm gear K 0Go (see Fig) rotatesl the sleeveiH `and consequently the" telescope mountedthereon about the axis of the hol vlow pin ceparallel'with the :axis'of'the trunnions, lays thesighting line on thetar'get and then followsithe movement thereof by' continuedA rotation of the hand wheels `T1 and/761; 'The sighting linel then lcoincides with the straight'line a '0 in `Fig.v l Vand the guide plane'of the voperating member M, when theaxis of tlievp'ivot pin of the gun carriage stands vertical, yas is' to be 'assumed with'respect to the vertical plane at c 01.' p y VAs soonVr as the angleV is determined Vin themannerzhereinbefore described, No. 2 of the *crewv 'regulates the'rotation ofthe hand wheel e2 in such away that'the reading off mark on the rib 3 now continuously pointsA (see F ig. 1) z'. e., it forms with the vertical plane passing throughV the sighting line, viz., the plane a c 01,;as is necessary according toy the description hereinbefore given, the angle 81. The gun therefore receives irrespecve of what height the target is at, always the exact traverse l.

Finally in order to adjust the gun to the angle of elevation corresponding to Vthe range of the target, No. 3 of the crew rocks by means of the elevating gear the gun barrel A about the axis of the trunnions b1 until the shaft G1 coupled to the one trunnion by the connecting Irods F and the sectorattached thereon has reached an angular position, in which the graduation mark of the graduation g3 (seeV Fig. 5), which corresponds to the range of the target is adjusted to the readingoitl" edge 7a3 of the aperture k2 provided in the sleeve H.' The longitudinal axis of the gun barrel then forms with the sighting line, which for the adjustment oi the gun barrel eilected by the elevating gear retains the direction toward the target unaltered, the attachment angle corresponding to the range of the target.
