LIFEBOAT RELEASE.

Application filed December 31, 1921.

To all whom it may concern Be it known that 1, SIM E. ALLBIN, a citizen of the United States, and a resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Lifeboat Releases, of which the following is a specification.

Thi s invention relates to a life boat release and more particularly to means for releasing a life boat from a block and fall or other suspension means.

The object of the invention is to provide a releasing means of the above character which may be operative from the life boat with which the same is associated.

lit is also an object of the invention that the releasing means be positive in operation and durable in construction.

It is a further important object of the invention that the releasing means he not subject to acccidental operation for releasing a life boat.

Other objects and objects relating to details of construction. combination and arrangement of parts will hereinafter appear, in the detailed description to follow.

in the drawings:

Figure 1 is a longitudinal vertical sectional view of the life boat illustrating the application of the present invention and showing the boat when suspended previous to the operation of the releasing means,

Figure 2 is a similar view of one end of the boat and illustrating" the releasing means the position of the parts when the hooks are released being shown in dotted lines.

Figure 3 is a vertical sectional view taken substantially on the line 33 of Figure 2,

Figures t and 5 are views similar to Figure 3 taken on the line 4.-4 of Figure 2 and illustrating the crank shaft in its releasing and locking position, respectively,

Figure 6 is a perspective view of the releasing hook,

Figure 7 is a similar view of the release block. and

Figure 8 is a rear elevation of the release block.

Referring to the drawings more particularly, 10 indicates generally a life saving Serial No. 526,148.

boat of which 11 is the bottom wall and 12 the end walls. The boat of course may be of height and as well known these boats are usually suspended by davits, or the like, from the side of a vessel. through the means of block and falls as indicated at 13, Fig; ure 1, said block and falls carrying the usual clevises 14.

In carrying out the present invention a shaft 15 is mounted longitudinally of the boat 10, said shaft being rotatably supported by a plurality of bearings 16 said hearings in each instance preferably consisting of an L-shaped standard 17 which is secured to the bottom of the boat by the means of screw bolts, or the like, as at 18 and which carries at its upper end a pair of complemental members 19'by the means of bolts 20, said members 19 forming a split hearing or sleeve for the shaft 15. It may be mentioned that the bearings and screw bolts 18 should be made of material which is not subject to quick corrosion and rust. At a point intermediate the ends of the shaft 15 there is secured a T-fitting 21 which has extending therefrom at right angles to the shaft a short pipe 22 which is adapted to form a handle for rotating the crank. At each end of the shaft there is secured a rank member 23 which has fitted upon its crank portion 2 a sleeve 25, said sleeve being free for rotative movement and having formed therewith a lug 26 Figures 4: and 5.

To each side wall of the boat there is secured what may be termed a release block 27 which. is shown in detail in Figure 7 of the drawings. The block 27 consists in a substantially channel shaped member, of which 29 is the bottom or bridge portion and 30 the side flanges thereof. The bottom has provided therein suitable openings as at 31 to which bolt screws 32 extend for securing the same to the side wall 12 of the boat. The forward portions of the side flanges 30 are increased in width as shown and at their extremities curved upwardly as at 32 and each provided with an opening At the rear end of the enlargements there is formed a block or box 34 which is provided with a central longitudinal passage having fitted therein a sleeve 35, which is square in cross section and also which slightly tapers toward its forward end. in the opening 33 there is journaled a pin 86 which carries a hook 37, said pin passing through an opening in the bridge portion of the hook as at 38, Figure 6. The shank portion 39 of the hook 37 is free and reduced as at 40 to form a seat 41 which is adapted to engage beneath the end of a keeper 42, said keeper consisting in a pin which is adapted to slide in the sleeve and which is formed with a head 45:3 on its rear end. To the head 43 there is pivoted the one end of a connecting rod ll through the means of the bifurcated couple 1g 45, said connecting rod carrying at its other end a sleeve 46 which has threaded therein a bolt d7 which terminates at its othe' end in a bifurcated head adapted to stradsille the lug 26 carried by the crank member 23. The bifurcated head a8 is pivoted to the lug 26 by the means of a pin, as shown.

It is of course obvious from Figure 1 that the hooks 37 in each instance are ada 'ited to be connected with the clevis 14! of the block and falls 13. It is also believed hat from the foregoing description the o .rtion oi? the present device is clea apparent. its is obvious when it is desired to release a boat being held by the block and falls as at 13, the only action necessary is to rotate the shaft- 15 in the proper direction and l er the keepers 42 from the hooks 3?. l these keepers are lowered. or drawn downwardly sufficient to permit 1 'ollG shank portions 39 of the hooks to clear their keepers, then the hooks may turn upon their pivots 36 and become disengaged from the block and fall. A boat may be released very quickly by this arrangement and every possibility of the releasing mechanism hanging or refusing to operate is obviated by the simple construction shown.

It may be pointed. out tha the operating handle 22 of the shaft 15 need not assume the position as shown in the drawings if it is deemed to be inconvenient. For instance the outer end of the handl may normally rest upon the bottom of the boat and the same may be so arranged, t at upon lifting the leasin mechanism will be 0 aerated.

F or retaining the clevis in its associated hook 3'? there is provided a latch element 9 shown in Figure l. One of these latch elements are provided for each of the hooks 37 and consists in a finger having its one end pivoted as at 8 to the outer side the release block 27 and its forward ci l forwardly as at 7 so that when the raised in the position shown it will clo e opening of the associated book 37. i pin is provided as at 6 nich is threaded into an opening as at 5 of one side of the release block 27. Also an opening is provided as at 4: in the release block innnediately below the opening 5 for receiving the pin 8. The pin 6 is so arranged so that if desired the same may be removed and then the latch element 9 will drop from its position for closing the associated hook 37. The latch element 9 when in the latter position will not interfere with the operation of the release means, but will insure that the clevis 14 of the block and fall will not be disengaged from its hook.-

While I have shown and described the prefered form of my invention I wish it to be understood that I am aware of the fact that the construction, combination and arranpement of parts may be changed by those skilled in the art without departing from the spirit of my invention as indicated by the appended claims.
