The general purpose I seek to accOmpIish ,4 is to so move thegun relatively to the Wiesel as 'to compensateforv undesirable and voidable motions of the ship, such as woul ordinarily tend to render the aim of thejgu mordiiiicult. I

invention accomplishes the objects state terse? e? a lar e p op o s t 9 tacts. 34, 35, 36, 37. From the cont-actpoint' .1t may be impracticable to keep the 1 which are mounted upon a sleeve 9. carrying a gun 10. This arrangementis for the purpose of allowing the recoil of the gun to takeplace without disturbing the position of the carriage. a mutilated worm: gear is'engaged bya worm 12 mounted rigidly-upon a-j're'volnble provided with a" shaft 13.. This shaft is bevel gear 14 which meshes with another bevel gear 15 carried by a revoluble shaft 16.

This shaft is provided with -a coupling 17. 25

At 18 is a variable speed reversible electric motor having; a field 19 provided with a winding 20 and'also having a highspeed revol'uble armature21=mounted upon a shaft 22." Thisarmatu're is provided with a com: mutator 23. The ship mains are shown at 24-, 25, and wires 26, 27 are connected with these mains.

T'wo solenoids are shown at 28, 29, and are provided with movable cores, 28", 29. The

solenoid 28 is provided with stationarycontact'point-s 30, 31, 32, 33, the solenoid 29 be.-' ing. similarly provided with stationary. con- 33 a wire. 38 leads to the motor armature 2i 'and from the contact member 3.7 a wire 39 leadsto a variable resistance 40,- the latter being connected by a wire 41 with the armature 21.

The variable resistance is controllableat will by a slide 40 whichis set and left alone. This variable resistance'is'for the purpose of adapting the apparatus, as-a whole, sistance beingnecessary ll'l'iIlSttlIlCGS where the gun is very light, and vice, 'versa. The

f-variable resistance is also necessary in order" to give the apparatus for any given vessel a proper adjustment ascertainable by trial,

, as to current nceded'. The variable" resist.-

ance is useful further in choking down extra currents due to sudden stoppage and reversal of the motor armature.

A contact plate 42 is mounted upon the; movable core 28" andis adapted .toengage.

and disengage the stationary contact mombers 30, 31, 32, 33., Another contact plate.

43 is. similarly mounted upon the core 29 and adapted to engage the contact members 34, 35, 36,37. A wire 44 connects the sta- .tionary contact member 32 with-the .wire

A "sector .11, bar ing the form of slide", is I I shown at 62 andpasses directly through the 85 for guns of difierent sizes, m re 'B-' pose.

A wire 45 connectstogether the stationary contact members 30, 34. A.wi re 46 connects together the contact. members 31,

33, and the contactmembers 35, 37 are'connected together by a wire/17.

pendulum 48 is mountedfupon-a rod 49, the latter being suspended from adisk 50 mountedfupon bearings 51. These bearingssupport the disk 50 upon 'a circle 52 which .is similarlysuppbrted upon a circle 53 by aid of bearings- 53% By aid of a ball -j'ointj54 a'rod 55 is connected-with the disk .50. A turnbuckle 56 engages this rod and also, engages another rod 57. The rod 57' is provided with a ball head engagedin a bracket 59. -A slide is shown at 6. and extending directly throughthis slide is a post (ilrelatively to which the moved. An adjusting screw is bracket. 59. This adjusting screw is provided with a. handle 63 whereby it-ma'y be turned byfhand and whenever itis rotated, the bracket 59'moves up-or' down,-'as"the case may be.

. -l\I0unted"upon the slide 6o are boxes 64,65 .cont'aining spiralsprings 66, 67, and extend:

mg through theboxes are cont-act screws 68, 69 provided with milled -nuts70, 71 for securing them rigidly 6'9, mounted upon these screws in such a mannerthat one or the'other of the springs is compressed by a. contact arm 74, disposed 00 intermediatethe contact screws (see Figs.

1 and 2). This not only protects the. contact screws and the contact-arm frominjury, but compensates for movements of the gun incidental toits -eloadhngzwhen the gun is moving and not following .the relative movements of the ship, any accidental pressure exerted by. the contact arm 74' against either ofthe contact screws .68-

or 69,.can dono'h a'rm, It-isalway s neces 11o. sary that the 'current be cut oilwhile the gun is bei'ngreloaded, inmounts where a gun is brought to' loadingxposit-ion.

A sighting telescope is shown at 7 5, and a bar 76 is connected with this instrumentand is '12o provided with a. rack 77 which passes into 1 a'conne'cting clamp -78. The latteris provided with a manually-operated pinion v79,

which engagesthe rack 77 and is. adapted as raise or lower the sighting telescope 75. 1-25 The clamping bracket-78' is mounted upon a rod 80 which isfconnected at 82 with one of the tninnions-S ,(see Fig. -2),- the trunnion" being i rovided with a P1n 82 f01 thispur- 58 which is 80 in position. The 9 springs 66, 67 are connected with the con: tact screws 68, 69 by the aid of heads 68,

That is to say,

he shaft 76 isconnected with a shaft see {29 "is connected by a- 'ing post 73, andthe on the slide.-., That is, to say,

[same-direction the gun would be trained in such a manner that it would exactly compensate'for that degree ofroll.

The sighting telescope is operated movements of the gunfilVhen the muz'hle of .the latter is raised the front endof'the telescope is'raised', and when the muzzle of. thegun is lowered the front end of the teleis lowered. The purpose ofthewheel 79 1s t'oadiust the aggregate'l'eng'th of the.

rods 76, 80 and' thereby bring the line of sight of the telescope into a predetermined; position relatively to the longitudinal aris of the gun, so that when the'telescope' is'bn the target'the gun is trained upon it. v A-battery is shown at 84 and from it a wire'85: leads to a wire 86 which connects together the solenoids 28, 29. The solenoid wire 87 with the bindbinding post 72 is connected by a wire 88 with the solenoid Connected with the contact arm '74 is a wire 89 which leads to the'battery 84. By thus using a battery; current instead of the high potential current otherwisej obtainable upon shi board, excessive sparking is prevented.

' dulum 48 {pendulum .90 (see lower right-hand corner of Fig. 1) is mounted upon arod 91, the latter being supported by a disk 92 mounted upon lcircle s'. 93, substantially as. above described with reference to the penat the left of Fig. 1.

I A rod'94 connectsthe disk 92 with a rheostat slide 96 mounted upona rheostat 95. This rheostat is provided with a number of contact points 97,. successirely connected with a continuous windingQS:v The center of the latter is connected by a wire 99 with the main 25. From the slide 96 a wire 100 leads to a'slide'lOl'foi-ming part of a rheostat 101*. This slide is operated by a handle. 102 and a pitman 103. The rheo'stat is provided with contacts .104, the latter being conn cted witha winding 10:).- This rheostat, by a wire .106 with a slide 107 of another rheostat 107?, the latter being provided with contacts 108 and with a winding 109, and being with a grad 'ated scale 10?", same range in degrees as clinometer. v a

From the rhe'ost'at 107 a wire 112 leads to a slide113 of arheostat 113. This rheostat is provided withfc'ontacts 114 and with a and from the former a wire the field winding 20 of the motor. A wire '117connects this field winding v with .'t-he main '24.

j The' un is mountedin a turret- 118 pro vided, with an annular rack '119, and disposed internally of'this rack is a driving 120 which meshes. with it, this pinion being mounted upon a shaft-121 where by it may be rotated by hand or power. A driven'gear122 meshes with theannular rack 119 and is turned-by motions of the' gear is mounted-upon a shaft 124' is. mounted upon the.=gear 126 and is provided wihfa slot'12 7; lhis rod carries the-slide l13' of'the' rhe-ostat so. that; this rheostat is controlled directly by movements of the' turrefiff The hand lever 102 isdirectly under the control of the gunner-who si hts the un. Therheostat 107 is controllei u who may -havenothing directly to do with the sighting, of-thelgnn, degrees indicated by the clinoniet'er. Neither slide 107 con'stantlyb .He

sets this slide fromtimeto nometer as to the number of degrees the ship may be rolling. Thejrheostat 107,- is

designed to set the system. For instance; the ship rolls 15 degrees; now it becomes the duty of the operator of rheostat 107 to set his rheostat l5degreesl. If, however,. the ship keeps r0lling',15 degrees continually he does not change his-rheostat; but ifthe ship "varies in 'the ln'umber' of degrees which it rolls at an time, theoperat'or changes the rheostat accordingly; When this rheostat is, set for ,15 degrees and the 15 degrees the system is in perfect unisoh. The "difference between what this 'rheo stat 10]. is set at and then'umber of-degrees the ship rolls l'must be takennp' by the'rheostatlOlfjoperated'by the man who fires the'gun, i p It is plain that aside from the longitudinal motion of the gun causedby the turning of the turret and its contents; a gunteuds' ordinarily to have motions of different causes. Forinstance', the' rocking of the wessfel from'side to side might cause the. muzzle ofthegun to be raised and"depressed, and as this rockingis 'variable-in degreegiithe dippingv in degree. Again the ves- 'sel may rock in a plane representing its genlength and this motion may be variable.

Again, the partial turning of the turret may, vary the degree of inclination of thejgun, other things being equal. However,- notsiitlistanding the fact thatnmnyforces and their compositions mayplay upon the gun for the purpose of destroying'the gunners aim, it is also clear that aside fro'nithe motion of turningthe turret- (whi'ch is controllablefat will) the gun can be kept upon the targehor approximately soQifthe apparatus is so arranged. and handled that'the motor armature turns at appropriate but varia-ble rates of speed, and provided further that thedireetion-of rotation shall be such as, direction-of movement of the gun. f

.In my iipparatus the various disturbing factors tending to throw the aim of thegun; ofi" the target are separately compensated for by causing-them to reverse the-direction of rotation ofthe motor when such reversalis necessary; and to varythe speed of the motor when such variation is necessary, in

order to fully neutralize the undesirable' motions ofthe vessel.

The purposeof the rheostats 95, 101, 107 and 113*,is to so control the current strengh that the variable speed of the motor arnia ture will just eonnnensate the varying-speed of the-vessel relatively to the ideal constant. position desired for the sun. ,The rheo stat '95, being controlled by'i'he pendulum 90. varies'th e current with regard to the speed of the rocking of the vessel. The rheostat 101 operated directly by the gunner who is watching the target, is entirely arbitrary ,--Now I V and its connections in "such amannerthat the turret by its-rotation and by its having straight out to s the condition when the gun is pointeth say in its act-ion, being intendedto niakegthe con-l trol of the gun more, thorough and perfect.

For instance, if the gunner finds; as a matter of obseryatio'm-th'at notwithstanding all other compensating mechanism-his aim is at certain intervals at little too ow, he soon learns just how far-to move the 'hand lever l02 inorder to increase or diminish the motor current suiliciently' to produce adequate compensation of movement, thereby retaining the gun-continuously upon the target.

The rheostatflt)? is operatedzupon a-somewhat similar-principle. Some oilicer watches the clinometer 110. 1- By noting the degree of roll of the vessel, he' can determine how to operate the, rheostat' 107 so asto coin- -.pens'ate, or atleast to assist in compensating forthenumberof degrees'the gun must be tralize the inotion of the ship. The .ofiicer endeavors to so control the .rheostat 107 that the current, handled by it will at all -times represent the mean quantity of current necessary e 4 The partial turning of the turret may to gi e the meter proper Vary, Within proper limits, the angle-of in-' clination swept over by the gun in its vertical; movelne11t,'due to the rocking of th .vessel andto similar disturbing influences. For instance, :if the wessel. s heaving violently-abeam, and the turret be turned in such position. that the gun pointsstraight ahead, the ,rocking motion of the vessel --would"- have comparatively little influence upon the sighting of the gun whereas, other things remaining the same-if the gun he turned to a rightangle so as to point away, 1 say to the starboard, the angle .of 1ncln1ationicovered by thewvertical sweep of the gun may ibe. jconsiderable.

here arranged theIrheost-at- 113*- complete COIlt-l'O-l over-the rheostat 113, increases the CIlIIPiltwhen the gun 'ls' pon'ited arhoard, as compared w th instances he .can make the-aim perfect by manipulating the hand lever 102. It. even with the aid of this lever, he .15 still unable to get aperfect line upon the ta'rgelghe can at least bring the gun sullirienth near a elevated or depressed so as to virtuall}; neuproper training to enable him to catch thetargetat someintervalwhile the sight of the. gun is in transit across it. and this feat is rendered far less d ihcult as the hr] 11;:

zone of the gun is narrow, as above described. and the period of oscillation is the same as for thefull .roll of the ship.

In practice, the firing gunner, when un- ..able to train the gun quite steadily upon the,
