SHIP STABILIZER.
APPLICATION FILED NOV. 18. 191B.

- 'INVENIOR '7/ iT5L/J/fi0 /MA/Z UM/ ATTORNEY I sHlIr s'rABILIzEIt.
Application filed November 18, 1913.
To 'aZZwkom it may concern: I Be it known that I, TA'rsUJIRo' IMAIzUM a sub ect of the Emperor of Japan, "residing in Seattle, in the countyof King and State:
of Washington, have inventedcertain new and useful Improvements in Ship-Stabrlizers, of whichthe following is-Ean exact and the object of this improvement is to provide a simple and efficient device that may be used to prevent rolling or tilting of boats or ships in the water.
In a general way the device comprises a plurality of cone shaped pans or receptacles arranged in tandem one above another in spaced apart relation and provided at the lower end with a weight, several of such devices being adapted to be suspended from the sides of a ship, or boat to oifer resistance to the water and prevent the ship or boat from rolling.
This apparatus is particularly well adapted for use in connection with life boats although it is obvious that the same may be used on large or small boats of almost any type.
The invention consists in the novel construction, adaptation and combination. of parts of a ship stabilizing device as will be more clearly hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a view in perspective of one unit of a stabilizing device, constructed in accordance with this invention; Fig. 2 is a somewhat diagrammatic view in end elevation showing a boat equipped with this stabilizing apparatus and Fig. 3 is an inverted View in perspective of one of the cone shaped pans or receptacles embodied in the invention a portion of the same being broken away.
Referring to the drawings throughout which like reference characters designate like parts, the letters A designate relatively shallow cone shaped pans or receptacles that are preferably formed of non-corrosive sheet metal and have their upper circular edges or rims rolled over wires in well known manner to give them strength and rigidity as shown in Fig. 3.
i Specification of Letters Patent The edge of each pan I Al is perforated at three equidistant points aifound'fits peripm ery as indicated at B forthereception"of'j'55 links Qth'at pass thro'ugli the"perforations B and aroundthe wirededge offthe pans.
In forming one of these'stabilizingdevices a plurality'fof' the cone shaped pansfiare used in tandem ancrarranged one above "an 0 other, the links C .of the lowermost pan be-i ing oonnectedby chains or cables 1) with a conical weight E and the links in the edges of the respective pans being connected with each other by other chains or cables D.
The links C of the uppermost pan are con nected with three chains or cables F that unite and are secured to a single chain or cable F that is adapted to be connected to a boat as indicated in Fig. 2.
In practice two of these devices will preferably be placed near the bow of the boat and on opposite sides thereof and two will be placed near the stern, and on opposite sides of the boat as indicated in Fig. 2, the cables F being made fast in any suitable manner to the sides of theboat.
The cone shaped receptacles A when suspended in the water with the concave side uppermost offer great resistance to any movement tending to lift them so that when any force tends to rock the boat in either direction it will be counteracted by the stabilizing devices.
This apparatus is particularly well adapted for use on life boats at the time passengers are being lowered into such boats and when-there is a tendency for the passengers to become excited and tip the boats over. The apparatus may also be used to advan- 90 tage on large boats to prevent them from rolling in rough weather or when they are discharging passengers and cargo and may even be advantageously. used on canoes and row boats.
If desired one of these devices may be secured to the stern of a boat and used as a drag to slow down the speed of a drifting boat.
It will be readily understood that any desired number of the water resistance members or pans A either more or less than the number shown may be connected in tandem to form one of these devices.
The Weights E are just heavy enough to hold the stabilizers in extended position in the Water as shown in Figs. 1 and 2.
When this apparatus is not in use the pans A will fit one Within another so that they will not occupy much space.
It is obvious that changes in the precise form of construction of the various parts of this device may be resorted to Within the scope of the following claims.
WVhat I claim and desire to protect by Letters Patent is 1. Ship stabilizing apparatus comprising a plurality of Water resisting units adapted to be suspended from the sides of a ship to offer resistance to lifting movement each of said units comprising a plurality of shallow cone shaped pans arranged one above another in spaced apart relation, the peripheral edges of each pan being connected at three equally spaced points with flexible suspension members that extend upwardly and are secured to the sides of the ship and the lowermost pan having a Weight connected therewith.
2. Ship stabilizing apparatus comprising a plurality of shallow cone shaped receptacles adapted to be connected in tandem each of said receptacles having a Wired rim and having perforations at three equidistant points adjacent to and inside of said Wired rim, links adapted to pass through said per ferations and encircle said rim, connectors extending between the links in the several receptacles, a Weight suspended from the links in said lowermost receptacle and connectors secured to the links of said uppermost receptacle and adapted to be made fast to the side of a ship.
