APPARATUS FOR LOWEBING AND HOIS'IING LIFE-BOATS FROM THE DECKS OF'SHIPS.

lowering and hoisting or raising life boats.

from the decks of ships; and the object thereof is to provide an improved apparatus of this class which is simple in construction and-operation, and which may be used on any kind or class of ships, 01' vessels and by means of which a life boat may be easily and safely lowered when desired and also quickly and easily raised to the deck of the vessel; a further object being to provide an apparatus of the class specified which is operated by a single winch device, which winch device may be operated by one or more men; and with these and other objects in view the invention consists in an apparatus of the class specified constructed as:

hereinafter described and claimed.

the standards a of the supports a are davits Z), and these davits are provided with bolts 6 which pass through the slots a in the arcshaped braces a. The bolts 6 where theypass through the davits b are angular in form and the outer ends of said bolts are threaded and provided with hand wheels 6 and by means of this construction the davits Z) are free to swing in a vertical plane outboard and iii-board, and may be locked or secured in any desired position by turning the hand wheels Z1 v Between the horizontal base members a of the supports a are placed the; saddles c which'norinally support the boat 0 and placed midway betweenthe supports a and slightly inward-1y thereof, in the construction shown, is a winch device (Z. The winch device (Z comprises, in the form of construction shown, side frame plates (Z connected zit-the back or in-board side bytwo transverse bars (Z and d, and said side fralneplates are also connected, in the form of construction shown,

by rods (1 and (1 the first of which is placed The invention is fully disclosed in the folat the top outer corner. and the latter just inwardly of the bar d", and above the rod d is another rod d which also connects the side plates (Z of the winch device.

Passing forwardlyand backwardly through the winch device (I is a shaft 0, the ends of which are supported by Z-shaped bracket plates 0 secured to the opposite sides of the base portions and the standards (1' of the supports a, and this shaft is provided with two drums c on which are wound. or nviih which areconnected cables 1 which are passed around pulleys in the top "portions. of the standards a of the supports a .and also around other pulleys in the upper or free end portions of the davits b and from which they are carried down and connected with the bow and stern-of the boat by means of hook devices 1 or in any other preferred manner, and said cables are preferably provided ju'st above the hook devices f with stop blocks or similar devices f.

Secured to the shaltwithin the frame work of the-winch device 4 is a large gear 9 provided with a grooved hub g and pass around thevhub g of thegear g is a brake band 9, one end of which is secured to the rod d and the other end of which is connected at with an arm mounted on the roddi The outer or rear end of the arm 9'' is'slotted or yoke-shaped in form as shown at g", and mounted therein is a cylinder g through which passes a vertically arranged screw 9 and the lower end of the screw g is pivoted or rotatably mounted in. the bar (Z of the winch device (1 and the upper end thereof passes through the bar 1.! which forms a bearmg therefor, and said screw is provided at its upper end with a hand wheel g and by manipulating the screw the brake 9 may be operated as will be readily I of theclutch hub or member if is asupplemental clutch member 2' provided with the usualannular groove z' and pivoted at 2 1s a clutch arm z" the outer end of which 1s provided with a handled? and the inner end of which is provided with the usual clutch ,oke i havin inwardl directed lu s or y a: z:

,pro ections 17 which operate in the groove '5 and by means of this construction the supplemental clutch member 2' may be moved longitudinally on the crank shaft h and to-' ward or from the clutch member on the gear wheel 12.

The shaft h, as shown in Fig. 3, is provided with a spline l1, movable in a corresponding groove in the clutch member i.

" and by means of this construction the said clutch member is free to slide longitudinally on said shaft but cannot turn thereon.

' dles c.

In Fig. 4 of the accon'manying drawing the clutch members It and z are shown in connected and operative position in full lines, and disconnected or in inoperative position in dotted lines.

The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof. The normal position of the parts of the apparatus is that shown in Fig. 1, in full lines, in which the boat rests in the sad- If new it is desired to lower the boat into the Water from the deck of the vessel the proeedure is as follows :-Presuming that the brake is not in operation, and that the clutch devices It and z are in operation, the crank shaft It is turned so 1S t0 raise the boat 0 into the position, shown in dotted lines at w in Fig. 2, the hand wheel-s 7J3 are theXtJi-Uifid so as to permit the davits Z) to tion they rest on the horizontal base members a of the supports a. The boat 0 may then be loweredistill farther into the water i by turning the crank shaft h by hand in the same direction, or the crank shaft 11. may be released and the clutch devices h and 2' thrown out of operation and the boat ,allowed to fall into the water, and this falling of the boat may, if desired, be regulated by manipul-atii'ig the brake screw 9* and the brake band by means of the hand wheel y. 'l nstead of following the above description the boat may be dropped into the water from the position shown at m in Fig.;2 by releasing the clutch devices ft and 2', and this operation may also be regulated by means of the brake device if desired.

The operation of raising the boat from the water into the position shown in dot-ted lines at w in Fig. 2 and then lowering it into I the saddles a will be readily uiulerstood, all that is necessary, the clutch devices It and i and the brake devices being out of opera tion, being to turn the crank shaft 71 in the proper direction to wind the cables f on the drums 0" untilthe davits b are in the position shown in full lines in Fig. 2 and the boat in the position shown at ac, after which the hand wheels I) are turned so as to hold the davits in said position and the crankshaft it turned so as to lower the boat into the saddles c.

Any suitable means may be provided for l'iolding the clutch arm 2" either in the operative position shown in full lines in Fig. 4, or in the inoperative position shown in dotted lines in said figure. In Fig. 2 l. have also shown at I; a part of one side of the hull of the vessel, and by means of my improved apparatus as herein shown anddescribed the boat 0 in the operation of lowering and raising the sameis suspended clear of the hull of the vessel, and my improved apparatus is, as will be seen, well adapted to accomplish the object for which it is intended; and various changes in and modifications of the construction described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages. t In the construction shown the supports'a and arc-shaped braces a are composed of separate side plates secured' together and a central member a 'secured between the horizontal bottom portions a of said supports and the davits b when'lowered into the position shown at w in Fig. '2 rest on the outer end portions of the parts a as indicated in dotted lines in said figure, but these supports may he constrlicted in any, desired manner and may be cast integrally if desired.
