SHIP-BUFFER.

Specification of Letters Patent. Patented Dec. 18, 191 '7.

Application filed-July 30, 1917. Serial No. 183,490.

'the provision of a buffer adapted to be carried by the hull of a ship adjacent the water line thereof for protecting the hull against collisions with other objects such as a boat or wharf.

A further object of the invention is the provision of a plurality of buffer plates arranged in parallelism partially surrounding the hull of a ship, resilient mountin means being provided whereby the shocks incident to striking an object will be-absorbed and cushioned at the point of impact, while the hull carrying the device will not be injured.

With these general objects in view and others that will appear as the'nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described and illustrated in the accompanying drawing and then claimed.

In the drawing formin a part of this a plication and in whic like reference 0 aracters designate corresponding parts throughout the several views,

Figure 1 is a top plan view of the hull of a ship provided with the, present. device.

Fig. 2 is avertical sectional view through a portion of the device with a portion of the hull shown in elevation.

Fig. 3 is anenlarged elevational view of a portion of the hull and a portionof the device mounted thereon with parts of the device removed, and

Figs. 4 and 5 are sectional detail views taken upon lines IV-IV and VV of Fig. 2.

twill be understood that the device may be arranged upon any bufler therefor, the same being illustrated in connection with a hull 10- of a ship having the device surrounding substantially the entire sides and bow portion 11 thereof but being interrupted at the stern portlon 12 of the hull. 4

- Elongated guideways 13 are secured upright upon the outerside 14 of the hull 10 in form of boat as aparallelism and are provided with mounting blocks 15 slidably mounted therein adapted for receiving the inner ends of springs 16 within the sockets 17 of the said blocks, the outer ends of said springs being seated within similar-sockets 18 of suitable heads 19. Elongated strips or buffer plates 20 are secured to the outer faces of the head 19, whereby the said plates are arranged in plurality substantially surrounding the entire hull 1O excepting its stern portion 12;

Each guideway 13 may be provided with a desirable number of bufler ,lates 20 in the manner herein described, four of the same being herein illustrateda comprising the complete bufling device. I will be seen that by this arrangement the mounting guideways 13 and spring carried heads 19 may be spaced at suitable distance apart while the forward ends 21 of the plates 20 are secured together in advance of the bow 11 of the hull 10 and at such point of connection there is preferably arranged a prow 22 of suitable material, preferably resilient,

such as rubber. A strip 23'11'1ay also be arranged within the points of attachment of the opposite plates 20 for connecting each row of plates together inwardly of the prow 22 while suitable springs 24 are arranged ing adjusting nuts 27 threaded upon the bar at opposite sides of each head and whereby as will be apparent, the positions'of theheads 19 upon the bars 26 may be readily adjusted and retained by means of the nuts 27. Retaining screws 28 are also provided for the blocks 15 for hearing against the guideways 13 and maintaining the blocks 15 against movement when suitably adjusted relatively of the heads 19.

Pivoted struts 29 are arranged at the opposite ends of each rod 26, the said struts 29 being pivoted at their inner ends to brackets 30 secured to the hull 10 at points above and below the guideways 13, while the outer ends of the struts 29 are pivoted to collars 31 adjustably arranged upon the opposite ends of the rods 26 and retained in n device which will still be operative.

capable of absorbing shocks at difi'erent guideways arranged in parallelism secured to the hull, blocks adjustablyarranged in the said guideways, outwardly pro ecting springs carried by the said blocks, heads upon the outer ends of the said springs, elongated strips carried by the said heads in parallel superposed arrangement spaced from the side of the hull-and adjustable connections between the said heads.

2. In combination with a hull, upright guideways arran ed in parallelism secured to the hull, bloc s adjustably arranged in the said guideways, outwardly projecting springs carried by the said blocks, heads upon the outer ends of the said springs,

elongated strips carried by the said heads in parallel superposed arrangement spaced from the side of the hull, threaded rods passing through the said heads, retaining means between said heads and rods, and struts pivotally connected between the opposite ends of the said rods and the hull at points removed from the opposite ends of a the said guideways.

aeeaeoe 3.. In combination with a, hull, upright guideways arranged in parallelism secured to the hull, blocks adjustably arranged in the said guideways, outwardly projecting springs carried by thesaid blocks, heads upon the outer ends of the said springs, elongated strips carried by the said heads in parallel superposed arrangement spaced from the side of the hull, a resilient prow connected between the forward ends of the said plates a strip arranged within said prow between the forward ends of said plates and springs arranged between the said strip and the bow extremity of the hull.

4. In combination with a hull, upright guideways arranged in parallelism secured to the hull, blocks adjustably arranged in the said guideways, outwardly projecting springs carried by the said blocks, heads upon the outer ends of the said springs, elongated strips carried by the said heads in parallel superposed arrangement spaced from the side of the hull, threaded rods passing through the said heads, retaining means between said heads and rods, and

struts pivotally connected between the opposite ends of the said rods and the hull at points removed from the opposite ends of the said guideways, a resilient prow connected between the forward ends of the said plates a stri arranged within said, prow between the orward ends of sald plates and springs arranged between the said strip and the bow extremity of the hull.

In testimony whereof I aflizrmy signature.
