Peterson, 11221 Loch Lomond Drive, Los Alamitos, Calif. 90720 Filed Aug. 1, 1966, Ser. No. 569,355 2 Claims. (Cl. 114-235) ABSTRACT OF THE DISCLOSURE lIn order to propel a barge through the water, a tug is employed which enters a docking area constructed at the back of the barge; this docking area being open both top and bottom to permit the tug to fioat in the water while propelling the barge. There are a plurality of resilient or engaging members which engage the tug and are yieldable to permit limited Vertical movement between the tug and the barge.
When coupling a tugboat to a `barge it is essential to fit the tugboat into an open bottomed dock at the rear of the barge and then to provide yieldable grippin-g means which couple the tugboard to the barge, thus permitting limited Vertical movement of the tug relative to the barge to adjust to the movement of wave action on the ocean, lake, or the like.
This invention relates to an integrated 'barge and tugboat whereby these two units are coupled or connected by a fiexible, semiflexible, or yieldable means.
An object of my invention is to provide an integrated barge and tugboat for use on the ocean or Great Lakes, and particularly where swells or Waves are present, and where the yieldable or llexible coupling structure permits limited movement between the barge and tugboat so that excessive stresses onlthe coupling means will be reduced. i
Another object of my invention is to provide an integrated barge and tugboat in which greater control and maneuverability of the barge is provided, and which will eliminate the use of towing cables between the tug and the barge, particularly where the operation is on the ocean, lakes, bays, or the like.
Another object of my invention is to provide a barge with an open dock or slot in the stern thereof, and where the Vertical movement of the tug witln'n the slot or dock Will be minimal due to a tight but flexible coupling means between the tug and the dock. I
Still another object of my invention is to provide a novel integrated barge and tugboat where the coupling means between the tug and the barge shall be either pneumatically, hydraulically or mechanically actuated to eifectively hold the tug in position while the barge is being moved over the ocean, bay or lake.
While I have shown preferred embodments of my in- Vention, it is to be understood that other modifications may be provided which accomplish the prime result of coupling or connecting a barge and a tugboat in such a manner that there is a limited rnoVement possible between the barge and the tug induced'by swells or Waves on the ocean, bay or lake, and where excessive stresses on the coupling means is held to a minimum.
Other objects, advantages and features of invention may appear from the accompanying drawings, the subjoined detailed description and the appended claims.

FIGURE 14 is a sectional view taken on line 14-14 of FIGURE 13.
Referring more particularly to the drawing, the numeral 1 indicates a barge, such as those used on oceans, lakes, bays, or the like, and are used to move large quantities of material. The barge itself usually has no motive power, the engines being mounted in a tug 2, which is of usual and well known construction. The tug is positioned in a dock 3 at the rear of the barge, this dock being open at the top, bottom, and stern so that the tug may move into the dock area from the rear, and while both the barge and tug are iloating in the water.
In my invention the tug is so held or locked in position on the barge that it can effectively push the barge forwardly or rearwardly as desired, and due to the oceans swell or Waves a limited amount of Vertical movement between the tug and the barge is desirable so that the coupling structure will not be broken nor undue wear placed thereon. The dock 3 is defined at `both sides by rearwardly extending arms 4 and 5, which are an integral part of the barge 1 and which extend preferably for the full length of the dock 3 and encompass most or all of the length of the tug 2. To couple the tug 2 to the barge 1 so that the tug may steer the barge as well as motivate the same, I provide a plurality of disks or tires 6 which are mounted on a horizontal shaft or mandrel 7. The tires or resilient members 6 may be pneumatic, hydraulic, or solid tires, as may be required, but are sufficiently yieldable or compressible under the pressure of the tug 2 so that there will be a yieldable connection between the tug and the barge. A rib 8 is formed on the tug 2, or may be mounted on the inside of the arms 4-5, and the stern of the barge 1 as desired, and this rib extends horizontally and is positioned under the tires or resilient members 6 so that these tires or resilient members will bear against the rib, su'bstantially as shown in FIGURE 1. A second row of tires or resilient members 9 are mounted below the tires or resilient members 6 on the mandrel 10, and these latter tires or resilient members engage the bottom of the rib 8, and also bear against the front or pushing surface of the tug 2.
To provide a coupling means along the sides of the tug 2 and between the tug and the arms 4-5, I provide a plurality of horizontally spaced tires or resilient members 11-12 which are either rotatably mounted or may be statonary on mandrels 13-14 respectively. These latter tires or 'bumpers may be mounted either on the barge arms 4-5 or on the tug 2, and the tires may be either q z:) pneumatic, hydraulic, or solid, as found most expedient. The tires or resilient members 11-12 bear against the upper surface of the rib 8, and a second set of tires or resilient members 15-16 are positioned below the tires 11-12 respectively, so that the second described tires bear against the bottom of the rib 8, thus yieldably holding the tug 2 against excess vertical movement relative to the barge 1, b'ut permitting a certain limited amount of vertical movement between the tug and the barge to prevent excessive strain due to the ocean swell or Waves.
To keep the tug 2 from accidentally backing out of the dock 3, I may provide connecting cables or ropes 17 extending between the tug and the barge, substantially as shown. Due to the limited compressibility' of the various tires or bumpers 6, 9, 12 and 16, the tug will be held securely in position relative to the barge 1 and within the dock 3, so that the tug can both push and guide the barge as required. Also this tire compressibility absorbs the swell or waves in the ocean, lake, or bay so that no njury will result to themeans coupling the tug and the barge.
In FIGURES 5, 6 and 7, I have illustrated another means to couple the tug to the barge within the dock 3, consisting of a block or strip 18 which is mounted either on one of the arms 4 or 5 of the lbarge, or on the tug 2 as desired. As shown in FIGURE 6 the strip or block 18, formed of a suitable elastic, rubber, or plastic, extends into a groove 18 in the barge arm 4 or 5, and the resilient block is pressed tightly into the groove 19 by means of a resilient tire 20 which bears against one side of the block 18. In FIGURE 7 the reverse construction is shown to that illustrated in FIGURE 6, in that the resilient block or strip 21 bears against the outer surface of the tug 2 and is pressed tightly against the tug by the pneumatic tire 22. In both instances the resilient strip or block 18 or 21 has a frictional engagement with either the barge or the tug, and sufficient pressure can be exerted against the strip to insure a secure coupling between the tug and the barge.
lIn FIGURES 8 and 9, I have illustrated still another means of .coupling the tug 2 to the barge 1 consisting of a plurality of resilient tires or resilient members 23 which are either rotatably or fixedly mounted on suitable shafts or mandrels 24, which shafts or mandrels may be mounted either on the tug or on the barge as desired. The tires or bumpers 23 fit into a groove or slot 25 formed or constructed in the tug 2 or the barge 1, and the tires all fit tightly within the grooves 25 thus coupling the tug to the barge, but permitting limited Vertical movement due to the compressibility of the tires 23.
In FIGURES 10, ll and 12, I have shown still another means of coupling the tug to the barge consisting of a pair of large horizontally extending posts, tubes or shafts 26-27 which extend rearwardly'I from the' Stern of the barge 1. The tug 2 is provided with a plurality of outwardly extending rings 28 which are larger in diameter than the shaft 26 or 27, and each ring is provided with a pneumatic or hydraulic tire 29 which grips the shaft 26 or 27. Thus again the tug is coupled to the barge 1 by a resilient or movable coupling of a limited amount.
In FIGURES 13 and 14 I ha've shown still another means of coupling the tug 2 to a barge within a dock area, consisting of resilient tires 30 which are mounted in a yoke 31, the yoke 31 is in turn attached to a hydraulic or pneumatic ram 32 and this ram, when operated, will press thetires 30 tightly against the adjacent Vertical face of an arm 4 or 5 of the barge; or a reverse position may 'be provided for the tires 30 so that the tires can engage the outer Vertical face of the tug 2. The pressure of the hydraulic ram 32 is sufficient to frictionally hold the tires 30 tightly against its adjacent bearing surface, thus again yieldably coupling the tug to the barge and permitting only limited and lateral and forward or aft movement between the tug and the barge to prevent ocean swells from injuring the coupling structure.
Having described my invention, I claim:
1. An integrated barge and tugboat, said barge having a dock therein to receive a tugboat, means releasably coupling the tugboat to the barge, said coupling means permitting limited movement between the tugboat and the barge, a rib on the tugboat, said coupling means engaging both the top and bottom surfaces of the rib.
2. An integrated barge and tugboat, said barge having a dock therein to receive a tugboat, means releasably coupling the tugboat to the barge, said coupling means permitting limited movement between the tugboat and the barge, said coupling means including pneumatic tires positioned in the dock between the tugboat and the barge, and a rib on the tugboat, said pneumatic tires engaging both the top and bottom surfaces of the rib.
