ANCHOB-CABLE-CUTTING APPARATUS FOR SUBMARINE BOATS.

Specification of Letters Patent.

Patented Oct. 26, 1915.

Application filed Hatch 8, 1915. Serial N 0. 12,832.

for cutting the supporting cables of anchors carried by submarine boats so as to release the anchors in the event of accident to the boat, or in the event of the anchors becoming so tightly locked in the water-bed that they cannot be lifted by the hoisting apparatus.

The invention has for its object to provide a simple and elficient arrangement for protecting the cutting blades from the water when the boat is submerged, and thus prevent themand their'operating parts from being impaired through rust.

The invention consists in providing a casing or housing for the cutting blades, and in the peculiar and novel provision of a sleeve vention.

of lead or other soft metal providing a passage through the casing through which the anchor-cable operates, the said cutting blades being so arranged to provide a shearing out upon the said sleeve and thecable whereby the cable may be cut with the exertion of but little power.

The invention further consists in certain details of construction and novel arrangements of parts as will be hereinafter described and then claimed. 4

In the drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a diagrammatic vertical longitudinal section of the forward end of a submarine or sulnnersiblo boat illustrating the a 'iplication'of my in- Fig. 2 is a horizontal section drawn on a larger scale on the line a-a of Fig. 1. Fig. is a sectional view on the line 6-?) of Fig. 2, part of thesheave over which the cable operates being broken away.

1 designates the forward end of a submarine or submersible boat having an anchor well 2 arranged therein; and 3 desig- .nates the superstructure of the boat into which the upper end of the well 2 opens, these parts and general arrangement thereof being of the design common in boats of the Lake type.

Upon the top of the hull plating and having an opening which registers with the upper end of the well 2, is a casting -l upon which is mounted and secured in suitable manner, the base 5 of the lower half of a sectional casing or housing 6, each section having an opening 8 in which is held a sleeve 9, preferably of lead, but which may be of any' suitable soft metal. The said sleeve passes through the casing and has its ends bent or flanged outwardly as at Sand designed to rest upon shoulders 10 surrounding the openings 8. The sleeve 9 is held in place by nuts 11 which are threaded into the outer ends 12 of the openings 8, the

said nuts being provided with central openlugs and also with annular flanges 13 which are designed to fit into the respective ends of the sleeve 9, and also with knife edges 14:

'which are designed to engage and cut intothe flanges 9 of the sleeve 9 so as to provide water-tight joints and thus prevent ingress of water to the casing or housing 6 when the boat is submerged.

Journaled in bearings 6' formed in the upper and lower sections of the casing G, is an idle shaft 15' a segmental worm gear 15 loosely journaled thereon, the teeth of which are meshed'by a worm 16, carried by a shaft 16 journaled in the casing 3, and having-one end extended through the casing and provided with a bevel gear 17 which is meshed by a bevel pinion 18 carricd'at the upper end of a vertical shaft 19. journaled in a bearing '20 secured to the hull,

andin a stuflingbox formed in said bearing,

the inner end of the shaft bciug extended into the mum hull and provided' with a hand wheel 21 as shown in Fig. l.

The segmental worm gear 15 is provided with an extension 22 having a recess 22 in which is securely held a cutting blade 23 having a curved cutting edge as shown, and

secured to a boss :24 formed integral with having its inner cud. woun upon a drum (not shown) which may be of any suitable design, but grcfc'rably of thc 'clesigm shown in Letiscrs stem No: Z 16 ,059 gcsnitcd to Simon Lake, December 16. will?
