LAUNCHING- APPARATUS FOR LIFEBOATS.

Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed October 21, 1919. Serial No. 332,154.

To all whom 'it may concern.

Be it known that MANUEL REY GARCIA, a citizen of Spain, residing at Leavenworth, in the county of Leavenworth and State of Kansas, has invented new and useful lmprovements in Launching Apparatus for Lifeboats, of which the following is a specification.

The` object of the invention is to provide a safety device capable of application to vessels particularly of the type designed for passenger travel whereby in case of .emergency the life boats may be expeditiously and safely launched under such conditions as to guard against capsizing or injury to the boats, particularly when the launching must be effected while a rough sea is running, andwhereby the boats may as readily be hoisted to their normal positions -with reference to the gunwales of the boat or ship as similar boats usually occupy when supported by davits as in the ordinary practice.

To this end the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, it being understood that changes in forms and proportions may be resorted to within the scope of theclaims without departing from the principles involved.

In the drawings: p

Figure 1 is an end view of the apparatus as seen when the boat is in its normal position while the vessel is in motion.

Fig. 2 is a side view of the same.

4 Fig. 3 is a detail view in section of a por tion of the landing platform or stage to show the means for retaining the same in' a normal or housed position and also the. means for lowering the same when required.

Figs. 4 and 5 are respectively side'and edge views of the supporting grapple which is connected with the hoist pole.

Figs. 6 and 7 are respectively side and edge views of the castoii. hook.

Fig. 8. is a View of the retaining loop or ring of the casteil hook.

Fig. 9 is a perspective view of the upper end of one of the platform or staging guides.

Figs. 10 and il are respectively perspective and plan views of the end portion of one of the traveler bars'which traverse the stationary guides or tracks secured to the vessels side.

Fig. l2 is a detail end view of a portion of the platform or staging to show one of the horses or chuck blocks by which the boat is seated on the platform.

Fig.` 13 is a detail view in side elevation of one of the bolt retaining arms and a portion of the connected retaining chain bywhich accidental displacement of the bolt when seated is prevented.

Fig. 14 is a detail sectional view to show the means whereby the supplemental platform is connected with the main platform and the connection of the buoy cables thereto.

A Essentially the apparatus consists of parallel tracks or guides 2O preferably secured in vertical position and in parallelism' to the side of the vessel indicated at 211, and which may be secured to theexterior surface thereof, and upon which is mounted for vertical movement a platform or staging 22 adapted to support a life boat 23 of which obviously any desired'number, depending on the size of the platform,l may be supportedfor the simultaneous launching operation. The platform or staging 22 is provided with a depending traveler frame 24: consisting in the construction illustrated of a plurality of parallel bars 25 headed as shown at 26 in Figs.` 10 and 1l to engage slots 2T in the guides 0r tracks 2O,` suitable diagonalbracing, elements 2S connecting said travelerbfars to afford the necessary strength l and rigidity.

A dav'it or hanger post 29 is disposedlin an inclined position to project terminally over the path of the platform or staging 22, the outer end thereof being supported by a post 30, and connected. therewith by means of a bolt 3l or the equivalent thereof is a hanger 32 consisting of an yupper hook 33 for engaging an eye 34 in the lower end of the bolt 3l, and a lower hook 35 with which is connected a suspending chain 36 leading to and engaged by a castoff hook 37 attached as at 38 to the platform or staging. Said chain is designed to hold the platform or staging n its normal or housed position with the boat supported thereon, and when it is desired to lower the boat for launching the castoff ring or loop 39 shown in detail in F ig. 8 may by means of the trip chain or cord 40 be disengaged from the hinged tongue 4l of the castoff hook so as to re-l lease the eye 42 at the lower end of the supporting chain. The lowering of the platform with the boat, and' obviously the return of the saine to the normal or housed position is effected by means ofa cable 43 passing around fall blocks 44 and V45 kof which the former is engaged with an eye 46 in the hook 33 of the supporting shackle 32 while the latter is connected by means of an eye 47 with the platform. It will be understood that a winch (not shown) may be employed for controlling the cable y43 or for controlling a plurality of hoisting cables connectedV with as many platforms or stages as may be desired, so that a plurality of boats maybe simultaneously launched from different points on the vessel.

From the traveler bars'25 located beneath the plane of the platform ork stage 22 there extend diagonal braces 48 to sustain the weight of the platform and its load, and carried by the platform are the horses or chuck blocks 49 combining at the bow and stern of the life boat to form seats for the reception of the -hull of such boat, retaining chains 50 being connected with retainer arms 51 extending transversely from the ends of the horses or chuck blocks and connected over the llife boat by means of castoff hooks 52. When a boat is about to be lowered these retaining chains may be loosened as indicated in Fig. l2 to permit of the floating of the boat as soon as it reaches the water, the purpose of said chains being obviously to prevent the accidental displacement of the boat from the seats vformed by the horses when the platform or staging is in its normal position as indi-g cated in Figs. l and 2.

The lower ends of the guides or tracksl which extend below the plane of inward curvature of the hull of the vessel are braced as shown at 53 so as to positively guide the platform and the traveler bars connected therewith to a depth sufficient to float the life boat free from the rests or seats formed by the horses or chuck blocks.

Suspended beneath the main platform or staging is a supplemental platform 54 designed to act as a fender to prevent injury to or excessive jarring of the main platform as the latter is lowered withl the boat, said supplemental platform being connected with the main platform by means of bolts 'extending through spacing tubes 56, and connected with'the supplemental platform are cables 57 extending through guide tubes 58 4on the edges of the main platform andv connected to cork'floats or buoys 59'which normally may be housed between the planes of said auxiliary and main platforms, but which when the apparatus is submerged float to the surface of the water at the front and rear edges of the platform or staging to serve as a guide to the occupants of the boat in positioning the latter above the platform when it is desired to hoist the boat to its'normal or elevated position as indicated in Figs. l and 2.

What is claimed is: Y f ,l
