SPEGIFGATON forming part of Letters Patent No. 234,7?9, dated July 28, 1.993. Application filed November 24, 1902. Serial llo. 132.528. LNO mofdel.)

.To all. when@ it "may concern:

Be it known that I, `W1LLIAM il. VrvIAN, a citizen AOt the United States, residing at Gloucester, in the county of Esser. and State of Massachusetts, have invented new and useful Improvements in Cannon, of which the following is a specitioation.

This invention relates to improvements in cannon for war-ships or n. the supporting carriage resting open a Stationen different angles., the oh when mounted upon a carriage for ieldpieces.

The invention consists in e cannon, a sleeve eccentricall y mounted thereon, an d a suitable support upon which said sleeve is rotatably inounted. f 2

The invention agr-.in consists in a cannon, a sleeve eccentrically mounted thereon, and an annular ring in which'said sleeve isrotatably mounted.

The invention. finally consists in the combination and arrangement of parts set forth in the following specification, and particularly pointed out in the claims thereof.

Referring to the drawings, Figure l is a side elevation of a cannon mounted in accordance with my invention. Fie'. 2 is a rear end elevation of the same, showing the base of the carriage resting in a horizontal plane. Fig. 3 is a rear elevation similar te Fig. 2, illustrating the base oi' the carriage tilted at an angldwhile the cannon remains in the saine position with relation to a vertical plane extending through the longitudinal median line and through the sights as that shown in'Fiff. 2. `Fig. #i is a longitudinal section, partly in elevation, taken on line ai et of Fie. 2. Fig. 5 is a detail elevation of the front sight and a portion-of one ofthe eccentric flanges. ilig o is an enlarged detail elevation of the rear sight and e portion of the rear eccentric flange. Fig. 7 is an enlarged detail section of a poi tion of the rear eccentric fiange, annular rin?. and roller-bearings.

Like numerals refer to like parts throughout the several views of the drawings.

ln the drawings, 8 is a cannon of ordinary construction. 9 is a sleeve surrounding said cannon, in which said cannon is arranged to slide longitudinally.

10 10 ure ears fast to the can non 8 and hav ing recoil-cylinders 11 l1 fast thereto. The pistons of the recoil-cylinders re fastened by 'the rods 12,12 to the rear eccentric flange 13,

integral with the slect'e 9. The interior con struction of the recei`i-eylindors is not illus trated in the drawings; as it forms no part of this invention and is well known to those skilled in the art.. The rearlcccentric flange 13 and front eccentric iienge 1i are both in; tegral with the'sleeve 9 and eccentric to the bore of the cannon 8. Said flanges are' rota- .taoly mounted in an annular ring 15, foi-ined in two parts joined together by crc'iss-pieces'` 16 16. The cross-pieces 16 are provided with trunnions 17, integral therewith and pivotally mounted upon the cheeks 18 of' the carriage 19. The carriage 19 is preferably formed in two parts, the upper 'part '2O constitutinga table arrangedto rotate in a horizontalplane upon the base 21. In the said rear eccentric Harige 13 is 'provided a vertical slot 22 extending therethrough, and vupon the rear face of the'iiange 13 is fastened a plate 23, provided with affslide 24,' constituting the rear sight. Said slide 24 is provided with a sighthole 25 and with a thumb-screw 26,.by which it is held in .tired relation to the plato 23, the slide 2i projecting into the slot '22. The front eccentric flange 1 1 is provided with an aperture 27, and lin this aperture is located the stationary front sight 28. A

ln order that the sleeve 9 and the flanges 1B and 11i may rotate within .the ring 15 with the lleast possible friction, roller-hearings 29 Iand 30 are provided, the 'roller-bearings. 29

loeing located between the periphery of the eccentric cylindrical iange 13 and the ring 15. End roller-bearings 30 are provided between one face of the flange 13, adjacentto the bearing 29 are the periphery thereof, and a plate 3l, lfast to the ring l5 by screw-bolts32- The rollers of held in position laterally by heldto the ring l5 byscrewmeans ot a plate olts \see Fig. k4) between the forward eccentric ila-nge 14 and the ring' l5, the rollers of said bearing being held in 'position by plates 36 and 37, fast to the rin-g 15 by screw-bolts,

The operation of the cannon, mounted as hereinbefore described,is as follows: The cannon is free to slide longitudinally in the sleeve 9 and is controlled by the recoil-cylinders 11 411 in the usual manner. Vhen the vessel rolls, the base 21 may be moved from the position shown in Figl 2 to that shown in Fig. 3, and in this case the cannon 8, together with the sleeve 9 andl the flanges 13 and 14 integral therewith, maintains the same position with relation to a vertical ing through the median line of the bore of the cannon, so that the conditions and the position `of fthe sight are always the same with relation to the cannon and with relation to said 'vertical plane, as illustrated in AFig 8, in which the slot 22 is shown to be vertical and lie" in the vertical plane passing through longitudinal median line of the bore of cannon, the saine as in Fig. 2, in which the base 2l is horizontal. It

Will therefore be seen that as the support upon which the hase 21 rests assumes d iiii'erent angles, either when 'said support is a vessel ,or when it is the carriage of a field-piece, the cannon and the sie-:ey e surrounding said cannon will always maintain the same relation to a vertical plane passing through the longitudinal median line oit' the bore of said cannon and that the sights `will also maintain the same relative location in relation to said plane, and therefore that under all conditions the accuracy with which the cannon can be aimed in using the front and rear sights is not interfered with. y

It will be seen, that while l have illustrated the sleeve 9 as provided with two eccentric flanges 13 and 14 for the sake olA convenience in construction and for saving metal said sleeve might be made as a cylinder Without Roller-hearings are also providedplane passianges, the periphery of said cylinder being; of the diameter of said flanges, and the cannon eecentrically mounted in said sleeve `with relation to the periphery thereof Without departing from the spirit of my invention.

Having thus described my invention, what l claim, and desire by Letters Patent to secure, is-

1. A cannon, a cylindrical sleeve eccentric; ally mounted thereon, and a suitable support upon which said sleeve is rotatably mounted.

2. 'A cannon, a cylindrical sleeve eccentrically mounted thereon,'and an annular ring in which said sleeve is rotatably mounted.

3. A cannon-a sleeve mounted thereon, cylindrical flanges upon said sleeve eccentric to the bore of said cannon, and an annular ring in which said flanges are rotatably mounted.

4. A cannon, a sleeve mounted thereon, cylindrical flanges upon said sleeve eccentric to the bore of said cannon, an annular ring in which said flanges' are rotatably mounted,

trunnions integral with said annular ring",I

and a carriage upon which said trunnions are pivotally mounted.

5. A gun-carriage, an annular ring pivotallly supported thereon, and a cannon rotatably and eccentrically mounted Within said ring.

G. A cannon, a sleeve mounted thereon, two cylindrical flanges integral with saidA sleeve eccentric to the bore of said cannon, said flanges provided with apertures'to receive a front and a rear sight, and an annular ring in which said flanges are rotatably mounted.

7. A cannon, a sleeve mounted'thereon, cylindrical flanges upon said sleeve eccentric to the bore of said cannon, an annular ring in which said flanges are rotatably mounted,

and roller-bearings interposed between said flanges and ring. I

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
