To all whom it'may concern:

Be it known that I, WILLIAM-JOHN in, the county of of the city of Toronto,

Canada,

York, iii-the Erovinoe of Ontario,

of which the following is the specifigiation. p

- My invention relates to improvements in releasing hooks for life boats and the like and the object of the invention is to provide a simple device conveniently'located in the boat for simultaneously operating the ,releasing means of the hook at each end of the "boat so as to simultaneously and instan=- taneously free the boat at each endimmediately the boat reaches each vdavit tackle and provided with a depending head, a suitable eye at each end of the boat, a hook engaging each eye, a spring lield sleeveconnected to the shank of'the hook contalninggrlpping jaws-designed to grip the depending head of the eye 0on nected to the davit tackle, a cable connected to each of the spring held sleeves of the boat I supporting hooks and extending down beneath the gunwale' of the boat through a tube leading from each end to the center of the boat so as to leave the central portions 'of the cable exposed, a supporting block depending beneath the gunwale; in proximity to each inner end of the cable contain ing tube, a handle provide'd with blocks supported by the central portion of" the cord between the aforesaid blocks depending from the gunwale as hereinafter more particularly described the following specifi- 5 0 indicate correspond .stern portion with-eyes A and A cation; I

It will be noticed that the central portion of the cable Gr extending betweenthe lnner ends of the tubes F and F is exposed gunwale of the boat in proximity to the inner endsof the tubes F and F and over which, the central portionof the cable G passes so as to support the same;

part of the davit tackle eye 0 thus freeing the boat simultaneously and instantaneously ..:t each end. To prevent the hooks D and.

and D from coming out of the eyes .A and A when the hooks are freed, I wind suitable wire K around the hooks as shown in Fig. 1 so as to prevent the hooks from coming out of the eyes. To prevent water getting into the sleeve D I provide a rub her cap L fitting over the top -of the sleeve and around the steinG andof the eye G.

.The stem C is'providd with a rib (3* so that there will he a closer connection between the rubber cap and the stem.

From this description it will be. seen that I haie devised a very simple device whereby a life boat when lowered into the water may be instantaneously and simultaneously released at both ends thereby minimizing the 1 danger of the boat capsizing inrough water.

What I claim as my invention is.

1. A releasing hook for life boats/com prising an eye member having adepending head at one end, a hook member having up.-

Copies of this patent may be obtained. 10'! wardly projecting lugs'between which are pivotally mounted gripping aws'designed to engage said depending head, and a sl d; ing spring-held sleeve inolosing said gripplng jaws, with means for operating same,

substantially as described.

' 2. A releasing hook for life boats comprising an eye member having a depending head at one end, a hook member having two upwardly projectlng lugs between which are WILLIAM JOHN HUFF.
