LOUIS JONEZIC, 0F JOLIE'I, ILLINOIS.

SHIP-RETARDING DEVICE.

Application filed January 22, 1921.

To all 4.071 am it may concern Be it known that I, LOUIS JoNnzio, a citizen of J ugo-Slovakia, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Ship-Retarding Devices, of

which the following is a specification.

This invention relates to certain new and useful improvements in ship retarding de vices, and has particular reference to the provision of hinged plates carried by the outer sides of the hull of a ship normally lying in flat engagement therewith and adapted to be projected laterally thereof for retarding the forward travel of the ship.

The primary object of the invention resides in the provision of an attachment to a ships hull adapted to be moved to a position to prevent the forward movement of a ship to retard such movement and bring the ship to a sudden stop to prevent collisions and other accidents.

A further object of the invention embodies a device for retarding the forward travel of aship in the form of plates hinged to the outer sides of the hull of a ship with each plate being independently operable for retarding the forward movements and also capable of cooperation with the ships rudder to provide for a short turning of the ship.

With these general objects in view and others that will appear as the nature of th invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim.

In the drawings forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a side elevational view of a ship equipped with the present invention showing the movement-retarding plates lying adjacent the sides of the ships hull,

Fig. 2 is a top plan view of the same showing the plates extended outwardly,

Fig. 3 is a detail horizontal sectional view showing the side plates lying adjacent the sides of the ships hull with the mechanism for projecting the same,

Fig. 4. is a detail sectional view taken on line IVIV of Fig. 3,

tion of one of the arcuate guides for one of the guide rods of the retarding plate.

Fig. 6 is a detail sectional view showing the operating gears and the rack bar for shifting the retarding plate and Fig. 7 is a cross sectional view taken on line VII-VII of Fig. 5.

Referring more in detail to the accompanying drawings there is illustrated a ship 1 of any conventional type equipped with the present form of device for retarding the forward movement thereof, the devices embodying plates 2 hinged to opposite sides of the ships hull and normally assuming a position in engagement with the sides as shown by full lines in Figs. 1 and 2 with the plates adapted to be projected laterally of the ship to the dotted line positions shown in Fig. 2 for retarding the forward movement.

The plates and their specific mountings together with the operating mechanism therefor are shown more clearly in Figs. 3 to 7, the plate 2 being hinged at its forward edge as at 3 to the outer side of the ships hull. To provide a guiding means for the swinging end 2 of the plate, the hull of the ship is provided with spaced vertically alined arcuate tubes 4 extending inwardly of the hull as shown in Fig. 3 with the curvature of the tubes centering on the plate hinges 3. i

A curved link 5 pivoted as at 6 to the inner face of the plate 2 extends into the tube 4 and carries a plunger head 7 at the inner end thereof, the tube being closed at its inner end to prevent the entrance of water from the tube into the interior of the ship.

The mechanism for projecting the plates 2 laterally of the sides of the ship embodies an arcuate rod 9 centering on the hinge connection 3 and pivoted at its outer end as at 10 to the inner face of the plate 2, the rod 9 passing through a boss 11 and a packing gland 12 of water-tight construction.

A bracket 13 carried by the inner face of the ships side has a pinion 1 1 journaled in the inner end thereof in engagement with rack teeth 15 formed in the base of a groove upon the inner side of the rod 9, shown more clearly in Fig. 6. A gear wheel 16 fixed to a shaft 17 journaled in brackets 18 is in constant engagement with the pinion 14 and upon rotation of the shaft 17 the gear and pinion are revolved to effect movement of t e rod 9.

In the operation of the device, a suitable source of power applied to the shaft 17 rotates the gear 16 and pinion 14: to move the rod 19 outwardly of the sides of the shaft as shown in Fig. 2, the plate 2 moved outwardly upon its hinge connection 3 being guided and braced by the arcuate rods 5. The plunger heads 7 upon the inner ends of the rod will cushion the movements of the plates in opposite directions, the plunger heads being of slightly less diameter than the arcuate tubes l to permit the escape of water at the periphery thereof. Should a ship, equipped with this device encounter an obstruction, the plates 2 may be moved outwardly to retard the forward movement thereof, and either of said plates may also be alone operated to provide a short turning of the ship. 7

While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is A ship retarding device in combination with a ship, hinged plates carried by'the sides thereof, arcuat'e tubular members carried by said ship. guide rods carried by said plate extending into the'ship and having a longitudinal groove cut in the face at the inner are thereof with rack teeth formed in the bottom of the groove, a pinion journaled adjacent the arcuate rod and having one edge extending into the rod groove for engagement with the rack teeth, and a vertical shaft carried by said ship having a gear upon one end for engagement with the said pinion and the pulley upon the opposite end for rotating said shaft. I

In testimony whereof I affix my signature.

LOUIS J ONEZIC.
