@nitro taies atwt @ffice CHRISTIAN eo'rTHoLD MEINHARDI, or ALrooNA, AssIeNoR To HIMSELF AND BENJAMIN r. BELL, or A-NfrIsfroWN, -I nNNsYLvANIA- i Leners Patent No. 80,869, dated August 11, 186s.
IMPROVEMENT IN SHIPS DAVITS.
'ro ALI. wIIoM 'I'r MAY eoNcnnN: Y
l Beit known that I, CHRISTIAN GorrHoLD M-EINIIARDT, of Altoona, in the 'county of Blair', and State of Pennsylvania, have invented a new and useful Improvement in Ships Davits; and I do hereby declarethe following to be a full and correct description of the saine, suiiicient to enable others skilled in the mechanical art to which my invention appertains to fully understandand use the same, reference being had to the accompany- Aing drawings, which make part of this invention, in which v Figure l is a side elevation of my improved davit.
Figure 2 is a sectional end view of the same in line a: z, iig. 1.
Figure 3 is a sectional view ot' the side of the frame opposite to the one shown in fig. 1.
Like letters indicate like parts in the several figures. My invention consists in placing an iron davit into a movable frame, and making this answer the purpose A, in Athe drawings, may'represent the davit, provided with a roller or sheave, a. The davit Afis provided with a colla;` or flange, b, resting o n the top of the frame or casing B, that part of the davit A below the collar l) passingV through au opening in the top plate of the casingB, and having a pintle on its lower end, which.
passes through a hole in the bottom of the casing I3, an'd may be secured by a pin, 0,'in such a manner, that while the davit is held by the casing it is free to revolve in'the same. I
C C aro the sides of the casing B, and form the bearings of two shafts, D'land E. The shaft D bears two cog-wheels, l (if, one on the outside of each side C and the .wheel 0lV having apawhf, over it, and the wheel cl gearing with alnrger cog-wheel, e, on the shaft E, which latter is provided with a winch, F, on which the hoisting-rope is wound up. V i
vTlhrongh the other end of the casing B passes an iron rod or circular` bar, G, provided at its lower partI with a collar, g, and three-pointed foot, The casing B rests-with this end on the collar g and foot gl, while,
at its other end it is provided with a caster-roller, g2, of any description, suitable to bear the weight, the roller itseli` being placed at right angles to the length of the casing. Y Y
The bar G is providedat'its top part with a screzwthread, h, and is connected to a hook, H, having a screwthread, it', in opposite direction to the screw-thread 7i, by means of a sleeve, I, provided with right-and-left female-screw threads in such a manner that, when the sleeve I is turned in one direction, the bar G and hook H are brought nearer to euch other, and when turned in the opposite direction, they are brought further away one from another. i i
A hook, AJ, serves to support the davit A, and may be screwed into Athe latter, or be attached to a band around it, as shown in the drawing. It hooksinto Van oye, j, on the hook H.
Its operation isv as 'follows:
When it is to be used, the davit is rolled, on the rollerrg to the side ci' the vessel, and the hook Gr passed over the railing, to which it is secured by the screw t'. The foot g1. standing on the deck with its three points, is firmly secured to thesame by turning the sleeve I. The davit A may now be swung around in the casing B at pleasure, or with thc latter on the caster-roller g2,- as, forinstance, when passengers are to be lowered from a burning vessel, they mayV get into the bloat onthe deck oi' the vessel, and thus avoid the danger of being lowered into a boat which is being tossed up and down by a heavy sea. The boat being filled, is hoisted up, theA davit swung around, and theboat may be provided with a detaching-device to'place it safely on the water at the right moment. Y f.
A great danger to passengers is that,in case of fire, often no access can be had to the davits, always placed near the poop-deck, on account of the ames, and boats have to be pitched overboard at the risk of their overturning and being immediately swamped. i
My device overcomes this dithculty. As it is movable, it can be used anywhere on board of a vessel as long as there are any bulwarks to attach it to, and it does not matter whether they are high or low, as it is made adjustable by means of the sleeire I.
It also aordsnn easy means for hoisting goods into the several hntchways of a. vessel, a-s will be `easily understood.
Having thus described my invention, what I claim as new, :rnd desire to secure by Letters Patent, is`
The easing B, in one end of' which swings the davit A, provided with :L caster, g2, swinging around the bar G, which is secured by the three-*pointed foot g1 and hooik H, and operated by the sleeve I, substantially as and for the purposes described.
