ATEN' FFIC GHR IS TIAN GERBER,

or MORGAN, UTAH.

To all whom it may] concern:

Be it known that I, CHRIsTInn GERBER, a citizen of the United States, residlngat Morgan, in, the county of Morgan and State of My invention relates to ship-bow shields.

and shock absorbers and has for its object to provide a shield for the bow of a ship which will act as a shock absorber and deaden the force of the contact when the ship on which it'is placed strikes another vessel or some-other obstacle. Tl16S6'Ob38CDS I accomplish with the device illustrated in the accompanying drawings in which similar letters and numerals of reference indicate like parts throughout the several figures, and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawings in which I have shown a substantial embodiment of my invention, Figure 1 is a side elevation of the front portion of a ship equipped with one of my shields. Fig. 2' is a vertical longitudinal section through the same. Fig.3isa plan view of the same portion of the ship with the deck removed showing the device in place thereon. Fig. 4 is a horizontal section on line 00 :0 of Fig. 2. Fig. 5 is a horizontal section on line a z of Fig. 2.

When a ship strikes a vessel, iceberg or other obstacle with its prow or how end, damages are frequently the result even when the ship is not moving with any great speed; and when the speed is great serious loss may occur.

It is the purpose of this invention to provide a shield which is secured to and covers a portion of the bow end of a ship that will deaden the impact and protect that portion of the vessel.

In the drawingsfiled herewith the bow of the vessel is shown at A and the shield complete as B. Said shield is constructed with an outer covering 1 shaped to conform to the bow of the vessel and normally spaced therefrom. A vertical beam 2 is secured within the apex of said shield or covering made of strong material and provided with recesses 3 which are cut or mortised in the open edge thereof. Horizontally placed buffer bars are carried in the front portion of the vessel extending forwardly therefrom Specification of Letters Patent.

and each having a pivot ring or plate 4: thereon. Said shield B is fastened in place on the vessel by said rings or plates t being inserted within said recesses 3 and pivot bolts 5 secured transversely through the sides 1 of said shield and passed through holes in said pivot plates 4. Said bufier bars are slidably carried in pipes 6 which are secured in place in the frame work of the vessel. Secured within the hold of the vessel and to the heavy frame work thereof are'cr'oss braces 7, 8, and 9. On the upper of said buffer bars, shown at 12, is carried a spiral spring 13, one end of which bears against a collar 1 1 that is rigidly secured on said buffer bar 12, and the other end bears againstthe cross'brace 8. This construction and arrangement allows said bufi'er bar 12 to be moved longitudinally inward against the compression of said spring 13 which spring normally holds said collar 14: against the inner side of the bow of the vessel. The next lower of said buffer bars 15 is yieldingly held extended and allowed limited'longitudinal movement within its pipe'6 by a similar spring 16. The next lower of said bufler bars 17 has a cross-head 18 firmly secured on the free end thereof, and a spring 10 is carried on said bar that tendsto hold it extended. On the end pore tions of said cross-head 18 are secured two parallel horizontally disposed bars 19, with their free ends slidable through openings in the cross brace 9. On each of said bars 19 is carried a spiral spring 20 which is compressed when said buifer bar 17 and crosshead 18 are moved horizontally inward. On the next lower of said bufier bars 21 I preferably carry two spiral springs 22 and 23 each held between a collar 24 and 25 respectively and the cross braces 8 and 9 adjacent.

In the lower hold of the vessel I provide two parallel buffer bars 26 with pivot plates 3 similar to those on the front end of the other bufier bars. On each of said bars 26 is carried a spiral spring 27 which normally holds said buffer bars in their extended position but will allow them to be forced horizontally inward to a limited extent.

Should a vessel upon which my device is fitted strike an object on the upper portion of the shield, the upper buffer bar would be moved longitudinally inward, and the spring 13 would be compressed. The other buffer bars would be in their order downward each moved lessthan the one above while the springs thereon would "becompressed correspondingly. Should the contactbe lower and more vertically centralon the shield all of said springs would be compressed in proportion to the movement of theshield toward the prow, the strength of I the springs determiningthe relative amount the impact was deadened; the momentum lessened and the final blow lightened.

Having thus-described my invention I desire to secure by Letters Patent-{and claim l. In a shieldandshock absorber for ship collisions, a V-shaped shield spaced from the bow ofthe ship: buffer'bars 'slidablycarried in the bow of the ship andto which said shield is pivoted; and spiral springs carried on said biifler bars to'no-rmally maintain the space between said shield and the bowof the ship.

"2. In a ship-bow shield and shock absorber the. combination of horizontally disposed buffer bars slidably carried in the prow of the ship and extended in front thereof; a V-shaped shield'pivoted on said buffer bars and spaced fromanda-round the prow of the ship; and spiralsprings carried on said bnfie'rbarsandwithin the prow'to normally hold said bars extended beyond the prow.
