T0 ALL yWHOM IT MAY CONCERN: l
i Be it known 'that I, JOHN- STRICKER BRADFQRD, ofthe city, county, and State of New York, have invented a. new and valuable Improvement in the Construction of Ferrry-4Br'idges, of which the following is a full, clear, and enact description, reference being hadto the drawings filed with the originel spet'zilicntion- Figure 1 isaplane view. i l l i Figure 2 is a vertical longitudinal section through the centre ofg. 1. "A represents an ordinary ferry`hridge`, whichrises and falls with the tide.. v B Vis my improvement, consisting of the-platform or grating, 4attached, at a slight angle of inclination inwarde, to the front of. and forming--a--pzrrtjot the bridge, and mayl be submerged, or adjusted at'or above the surface of the water,'c"onrstrueted of heavy double plenking, or-'timber, so placed, diagonally, as to leave open spnces for the water topass through, and Ystrengthenedby'kiiagon'al braces, (underneath of and forming a, part ot' the platform) placed nt such-'an angle as to receive the` entire strain from the 'concussion of the boat, on its entrance to the slip, surroundedibyn. raieed edge, and `with its inner Aextreme ends, at the bont-opening, so
rounded o as to act rather as erguido than un impediment tothe ferry-boat, in its ingress to or egress from the slip.
C is the line of the' ferry-slip. "D isahe water-line'. v
My invention ie designed asan absolute safeguard against loss of'life `by drowning, in thel event of a person .falling overbourd,`either 4from the ferry-bridge or bont, the entire water-surface, of the' hreoldtli of the slip, for
ftee'n feet, more o'r less, outwards from the front of the bridge, (with the vexception ofthe smell space to be occupied by the end of the boat,) being protected by the platform o r grting, the construction of which is such thatits angle ofinelination is suieient te'cause bodies falling on its surfaceto slide-inwards towards`the'bridge, and its raisedfedge (to the heightof which I do not limit myself) rendering it impossible for them to slide ofi1 atrthe sides, or at theboat-opening in theeentre, 'or to get beyond erover it into deep water.
p l What I claim as my invention, and .desire to slecnre by Letters Patent, is
A platformY or grating, attached to 'a ferry-bridge, whether submerged, or at or above the surface o f the water, constructed substantially as herein described, `and for the purpose set forth.
.LSTRICKER BRADORD.
