T0 ALL WHOM IT MAY'CONCERN I Be itknown that I, WILLIAMH.' Houston, ot' New York, of the county ot' New York, in the State of 'New York; have invented certain new and useful improvcmcntsl in Apparntus'for Launching or Lowering Overheard Small Boots; und I do hereby declare that the following,r is a full and exact description thereof, reference being had to `the.aceonfqxmyini drawings, making part of this application. Y Y

My inven'tion relates to the mechanism or device employed for effecting the launching ot' life-boats from ships, and has foi' its objects to readily and with certainty eiiect the rcleaseme'nt of the 'coat as soon it is fairly launched, And 'to theseends myinvention consists in an automatic boat-eyeor lock, so constructed and operating that when attached to the hook, by which the boat is suspended, it will automatically disengagc or detach itself from said hook the moment the boat, or that part to which said lock is attached, rests fairly in the nat-er.

Toenablc those skilled in the art to make and use my-invention, I will `proceed to describe more fully the constnut'ion and operation Vof my automatic or self-detaching liront-lockerl eye, referring by letters to Athe accompanying drawings, in which-Y l A i 4 f l Figure 1 is an elevation, illustrating a boat suspended ready to hc launched, arid having on it my invention.

Figure 2 is asimilar rien, showing the boat launched;v and lFigure 3 is a sectional elevation of the automatic or self-detaching device.A Figure 4 isalsimilar section, showing another form ofmy invention. 1n the several, ligures, A is a. life-boat, and B is the arm or dni/it," `from which the boatis suspended, by

means of the usual ropes C, passing through an eye in the outer end of said arm B, and proiiided with a suitable hoek, d. .To each lend of thc boat may be' 'attached securely one .of roy-automatic locks, as seen at F,'iigs.` l and 2.'l This lock is composed of'ametnllic stock orl stand portion, as shown at F, in which are arranged on' v each sidetwo vertical and movable hars 7i l, (see figs. 2 and 3,) which are so arranged as to be capable of a. compound vibratory and sliding motion, being hung en pins S S, which pass through slots 1 2 in the said bars h Z. To one of these bars 'lis pivotod at n, (seeiig) a. pawl, P, which is formed :1t-one end to catch andere Vshoulder at o, (seo iig. 3,) in 4theupper part of bark. The said hais h l are -formed with shoulders or projections at v w, on which bear the opposite ends of a spring, m, which passes -under n. cross-bar or pin z', and which throws down the bars Il l in the manner and for -the purpose-to beprcsently'explained U is asliding cam-bar 4,which raises thc bars h Z, and t o. catch or lock to hold said cam-.bnr in place.

' The operation of the seicral partstogcther may be thus explained: The lparts being adjusted 'andl locked in the position seen at figs. 1 and', theordinary hook d is placed on the pejjl P, as seen at viigt 1. As soon as 'the boat is thus held-and suspended on the hooks, the catch t being rasedout of the, notch in cam-bar v U,'thc latter is slid out, as seen at igf, when the pawl P andbars hf? will still retain their same relative .positions in consequence of-the weight of the boat being suspended from the pawl P, and the boat muy-be lowered with 'perfect safety, but just as soonasthe boat A i'e-sts in the water, as seen et iig. 2, so Athat the pawl P is relieved. ofv its weight, then the spring m immediately forces downward the hars h l, which spread apart or diverge om each other at theirl upper ends, as seen at iig. 2, so aste release the end of pawl P from ,thebnr Il,

and allow the hoolc dito slide cti' of said pani and the bont to go iree.4 When itis .desired to lift the-boat, the lock mechanism should be re-adjusted to hold the hook d. VBy the arrangement'of the pins S S, and slots l and 2, and spring m, the hars can he moved downward and upward in such a direction as to'sprcad open their upper ends and release the pawl P, os shownA and described. The said bars are'i'orecd up and togcthcrhy means ofthe inclines or cam surfaces of the sliding-bar U, (see iig. 3.) It will be seen that with the automatic device described the boat A, `can be safely lowered, andthot the moment the boat rests fairly onthc water that moment she is completely released by the automaticl operatonot' thc lock, ns already cnplnined. Anil it will be understood that in the use ofm'y'invcntion, if one end of the boat reaches the water first that end only will he let go, and the oiherwill lio let. go free as soonl esit rests on the water sufficiently to takethe weight ed' of' theropeat that end.

I At 5g. 4 have shoivn 'a modification of .the'apparatus, 'in which, in lieu. of two bars, I have only one har, and have the pani l? piyotcd at n in tholstock F of the lock., In this modification thespring n; is4 attached.

explained. I

' fairly on 'thewatelg.substantially'ns hereixibefore described.

at one end toi the-moin stock of the lock, ond at its other end piesses on the shoulder 1. l This form of lock requires of' course ohly'o'ne. incline on the bar U; it ie si'qipler, and mty-be formedl to Work quite as well as the other form,`shown 'in figs.' 1, 2, and 3.V It will ble understood that the detail form ,and varrangement o' the parts may he modified in al great variety o l'jways without depaiting from lthe gist of myinvention, which is in the idea. of the automatically Working piwl or, catch-bm', or its eq'uimlent, so combined with a iovable bar ]4, or its equivalent, that the former will serve to hol thewater, and will lthan become iminediately. disengagedat its vibrating or loose end 'sbstantially'as already .The combination of the cotdz-pawl P, locking-bar h, 'andsp'ring m, to operate as described-.uufthepurpose set forth.

I also claim an mltothzticl boat-eye or lock, so construct What I claim as new, AI zi'iCl-zlesi're to secune by vLetters Patent, is-
