TORPEDO-GUARD.

Application filed November 3, 1917.

To all whom it may concern:

Be it known that I, FREDERICK G. ROLF, a citizen of the United States, residing at El Paso, in the county of El Paso and State of Texas, have invented new and useful Improvements in Torpedo-Guards, of which the following is a specification.

This invention relates to a torpedo guard, and one object is to provide a plurality of units having pivotal connection with the side of a vessel and adapted to be raised to a position above the water line, so that the said units may be readily applied without the necessity of placing the vessel in a dry dock.

A further obj ect is to provide a plurality of units mounted as specified and each comprising a plurality of steel plates, which may be spaced apart forming an air chamber within each unit.

A further object is to provide certain novel means for mounting the plates comprising the individual guard members and permitting the latter to be raised out of operative position when desired.

IVith the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of elements hereinafter described and claimed.

In the drawings:

Figure l is a View in side elevation.

Fig. 2 is a similar view with the unit in inoperative position.

I Fig. 3 is a top plan View.

Fig. 4 is a detail view in top plan of certain of the securing devices.

Fig. 5 is a vertical section of one of the units proper.

Each unit comprises a plurality of steel plates such as 10 and 12, these plates being spaced apart by means of a suitable frame or the like shown at 13 and providing an air chamber 1 1 between the plates, whereby the shock due to the impact of a torpedo is somewhat lessened. It is the intention however to provide units which may readily be replaced when individual units are destroyed by the impact of a torpedo. The units are suitably spaced from the sides of the vessel by the supporting devices referred to below and the ship will not be damaged by the destruction of one of the members mentioned.

The supporting devices for the individual Specification of Letters Patent. Patented May 21, 1918,

Serial No. 200,107.

units comprise a plurality of upper arms designated 16, these arms being slotted as shown at 17 and being pivotally mounted in brackets 18 carried by the side of the vessel.

The lower curved arms20 are mounted in brackets 21 also carried at the side of the vessel. Diagonally extending arms or braces 22 each carry a pin 23 at the upper end and are oppositely located on the sides of arm 16 forming a forked brace, the lower ends of braces 22 being provided with eyes 23 through which a bar or pin 24 passes, this pin also passing through ears 25 mounted on brackets 21. Pin 23 at the upper end of brace 22 operates within a slot 17 in bar 16 and permits of the necessary movement when the pivotally mounted frames are elevated for the purpose of placing the guard units out of operative position. Each lower arm 20 is connected with an adjacent guard unit at a point 29.

The units are elevated for the purpose of placing them out of operative position by means of wire cables Or the like designated 30 controlled by any suitable winding means shown conventionally at 31 and carried on the deck of the vessel.

The movement of the pin 23 within slot 17 of the bar 16 is limited, this pin engaging the outer end wall of the slot when the bar is in horizontal position, and thereby holding the guard units in correct operative position.

What is claimed is:

1. In a device of the class described, a guard unit and mean for mounting the latter at the side of the vessel, said means comprising a plurality of outwardly extending arms provided with longitudinal slots, means for securing said arms to the side of a vessel, a plurality of spaced parallel braces pivotally mounted on the vessel at a point below each of the aforesaid arms one end of each brace being movable longitudinally of the arm and guided by the slot therein, the braces folding into position to partly inclose the arms, an additional arm connected with the guard unit, and single means for pivotally mounting the braces and arm last named.

2. In a device of the class described, a guard unit, and means for mounting the unit at the side of a vessel, said means including a plurality of outwardly extending arms having pivotal connection with the hull named, an arm, connected withv said bracket of the vessel, a bracket carried bythe hull of neans of' s aid pin and connected 1. at its the Vessel, a plurality of devices formed on outer end With the guard unit, and means 10 the bracket and constituting bearing memfor raising said unit out of operative posibers, a pin passing through said bearing tion.* 4 3 members, a brace pivotally connected with In testimony whereof I affix my signature. said pin and With one of the arms "first FREDERICK G.
