i .citizenw of the AUnited States, residing at oneormore of said wheels.

Brockton, Ain the county of Plymouth and State `of Massachusetts, `have invented new and useful:` Improvements in `Engines of Warfare, of which the following is a speciication.4 f v a The object of the presentinvention is to provide afself-propelled and armored .engine `of warfare. Theinvention is embodied in `two spherical metallic shells, one within theother, the inner shell being provided with `wheels arranged to: roll upon the internal "surface of `the outer shell, and containing a motor and drivin mechanism for driving The load carn riedby the inner shell is unequally distrib- 1uted `with relation to the center, with thel result that the inner `shell tends constantly f toassume a normal position with the greater part of the load at the bottom, and as the drivingjwheel or wheels rotate and tend to `revolve the inner shell from said normal position the `outer shell respondsto the tendrw ency of the inner shell to return to said nori `mal position. `The Vouter shell isthus re- Nvolved, and the engine is' caused to` travel u forward orbackward according to the direction of rotation ofthe driving wheels.

`The invention includes steering mechalaterallyiin relation to the louter shell, the

innershellbeing substantially smaller than the internal `diameterof the outer `shell to provide the necessaryfspace for such shifting. Asthe inner shell is shifted from right 'i 1 "to left the load carriedby the inner shell .i i lto shift the inner shell to the right relativelyW to the i outer shell thewlatterwill traverseaw Y `causes the outer shell to change `its course to the left until the inner shell is shifted `back to a median position. lOn the other hand ifthe steeringlmechanismlbe adjusted curved path toward the right until the inner shell is shifted back to said median position.` LThe engine is capableioftraveling onland i `or inwater. i When traveling onland it may `jfbetused for destroying objects fsuch as hyso` trolley Ywires,railway cars, andsmall frame drants,`rtelegraph poles, poles for supporting j ybuildingsfby collision.

both shells are provided with openings through which projectiles may be'red when the openings of the inner shell are` in line `with some of the openings of the outer shell.

Fig.2 represents a vertical section through `the structure intersected by line 2-2 of Fig.

1 looking forward.

Fig. 3 is a horizontal section through the structure intersected by line 33 of Fig. 1. Fig. 4L isa sectional view of a swivel connection of the steering mechanism.

Fig. 5 is a view of the plugs used for closing the port holes in the inner shell.

The same reference characters indicate the saine parts wherever they occur. The outer sphericalshellyas shown, `is made of two layers of metal, the outer layer comprising two hemispherical portions 10,

j 10 `that meet in edge-tdedge relation to form a joint at 11. Theinner layer of theouter shell. comprises two

hemispherical sections

12, 12 that meet in edge to edge relation to `forni ajoint at 13.v The'inner and outer layers are arranged so that the plane of joint 13 is at right angles to the plane of joint 11. When thetwolayers of the outer shell are bolted one to another they reinforce each other and relieve the joints of any undue strain. Aside from this structural detail the outer shell is to all intents and purposes a` spherical unit.

The external surface of the outer shell is provided with knobs or protuberances 14 to "avoid"slippinor on moist ground. The outer miran s'rnfrns PATENT OFFRE. f

. 51 comprisesbevel gears 59 and 60,;a shaft 61, and a handfwheel62, the latter being arranged within reach of the attendant of the propelling motor 25.` Shaft 61 is mounted in suitable bearings provided by a swinging hanger 63 and the latter ishung upon shaft 51.` Platform42 is cutaway as indicated at 64 to afford access to the propelling mo- .l

tor and to afford clearance for the steering shaft 6l. `The springs 58 exert their stress in opposite directions against portions 65 of the inner shell and the lateral position of. the latter is determined by the point at which ,1 the spring stressesare equal. Thepitch direction of the two screw portions 56 is the same, and consequently when shaft 51 is i j turned in one direction both nuts 57 will be `moved toward the right or left as the case `suicient force tomove it :laterally the shock i closure` 68 may be put in place or detached, 4o

would be taken up by the springs 58.

The two shells are provided `with open-` ings large enough to afford entrance to and exit from the inner shell. Such opening of the outer shell is indicated at 66 in Fig `1,

`and the opening of the inner shell 1s indicated at 67.` A closure for opening 66 is in.-

dicated at 68, said closure being capable ofm `moving toward the center of the shell, and being fastened in place byboltsu69. ,When` the `openings 66 and 67 move into registraq tion with each other as shown by Fig. 1 the as the case may be, and for the purpose of handling itI have provided the inner shell `with a swinging holder 70. This holder is mounted upon a pivot stud 71 and is provided With a Stem 72 that is arranged to pro` ject through opening` 67 when in use. The

" closure 68 is formed with a socket on its inner side, to receive the reduced end portion 7 2 of the stem 72, Fig. 1 showing the holder in solid lines as having been moved to take theclosure 68. j One end of a rope 78 is attached to holder.70.and the inner shell is provided with a pulley 74 over which the the position represented by solid lines.` Am

rope-may be drawn to swing the holder to i portion 72.of the swinging holder. Closure 76 would be held in place by bolts such yas those represented at 77.

Assuming that both the closures were fastened to their respective shells, and that the engine as a whole were traveling, the swing# ing holder would be retracted into the inner shell and lashed to `Prevent it from swinging and striking the other parts of the structurelorA the occupants. On the other hand, 4assuming f that the closures were and that it were desired to remove them from their respective openingsthe holder 70 would be` used` as follows: An attendant would draw rope 73 toward the anchoring` device 75 tomove the end portion` 72into the socket 76 of the` inner closure. The holder would thus be made available to sustain the closure 76 while unscrewing the bolts 77 to release the closure. Rope 73 would then be paid out to enable theholder to descend with the closure 76 mounted thereon. It would then be necessary to rej move closure 76 from the holder in order to usethe latter to take the closure 68 from its shell. Opening 67 of the inner shell is sufficiently large to enable closure 68 to pass through it, and both closures may be deposited upon the platform 42. 1

Closure 76 isprovided with a flange 78 that is adapted to be lapped in relation to a flange 79 that defines the opening 67, and suitable soft packing material may be provided to make the `joint watertight. The

vport holes 19 of the innershell may be made watertight by inserting closures such as that shownby Fig. 5. `This closure comprises a screw-plug portion 80, a flange` 81, and a polygonal boss 82 adapted to receive a wrench. The port holes 19 are formed with internal screw-threads adapted to coact with theexternal screw-threads of the plug-por.- tion 80. The flange81 is adapted` to bel pressedagainst the rim of a port hole and the joint may be made watertight by providing a washer or gasket of suitable material. Such washeror gasket'is indicatedat 83.

By means of the closures for the port holes, and that for the opening 67, the inner shell may be made sufficiently watertight. y The propelling motor represented conveney tionally at 25 is intendedto be a motor of the internal'combustion type, and the exhaust pipe therefor is indicatedat 84 (Fig. 3). A muffler is `indicated conventionally at 85. The outer end of pipe 84: extendsy through .brought into registration with each` other, j
