Z-Gifliflis;

This invention relates generally to towboats and othervessels, and more particularly to a boat used for salvage purposes, the device comprising a combination with such a boat of a tube extending substantiallyvertically through one end of a boat with a spud slidably mounted within this tube and having a fair lead on the upper portion of the spud, the fair lead guiding a cable, one end of which cable will be secured to the material to be salvaged from the shore, the other end of the cable being wound on a reel: on the deck of the boat','whereby the spud is" forced downwardly through the tube and provides. temporary anchoring of the" boat during the salvage operation, the invention including a second. cable securabl'e to the lower end of the spud whereby the spud may be conveniently raised. when the salvaging operation is com-- pleted'.

A. primary object of this invention is to rovide a device of the character mentioned, inwhich the component parts are constructed with extreme simplicity, susceptible of manufacture in very rugged. form, and generally adapted for whereby the anchoring; means. may be; easily retracted, when it is desired to move the boat to. a new location.

' Another object of this invention is to. provide means. of this character in which the controls of the anchor and the dragline are grouped togather at one point on the deck. of the boat.

And a last object to be specifically mentioned is to provide means of this character which is relatively inexpensive and practicable to manufacture, extremely simple and conveniently used under various conditions, and. which will. give generally efiicient and durable service.

With these objects definitely in view, this invention resides in certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail, particularly set forth in the appended claims, and illustrated in the accompanying drawings which form a material part of this application, and in which:

Figure 1 is a side elevational view of a salvage boat with this invention incorporated thereon, the view including the portion of the shore line and a log which is being salvaged;

Figure 2 is a fragmentary view of the portion 2. a of the structure shown in- Figure 1 the portion of the boat" being broken away to show the under lying structure in vertical section;

Figure 3 is-a view similar'toFigure 2 but showing the spud retracted;

Figure 4 is an enlarged detailed view of the spud, reel and contiguous structure, the tube wherein the spud is housed being shown in vertical section, the spud and tube being broken, to conserve space; and

Figure 5' is an enlarged top plan view of the spud, real and adjacent structure;

Similar characters of reference designate similar or identical parts and portions throughout the specification and throughout the several views ofthe drawings.

Referring now to the drawings in detail, the environment wherewith this invention is adapted to be used includesa log It, used to represent the object on the shore l2 which it is desired to salvage. A boat, generally represented at [4, may be of any desired type and will include a. deck l6 and a hull portion I 8. This invenfioni may be incorporated with either the front or bow portion of the boat or another portion of the boat, there being provided in every case a tube 26 which will be disposed in substantially vertical position and will extend to. said deck and hull portion. This tube 2.0. will preferablyhavean integral flange 22 on the lower en'd' thereof and the upper end. of the. tube will be provided with aflange 24'.

A spud 26,. preferably sharpened at the lower end 28. is slid'ably mounted within the tube 2.0, and. the upper end. of. this spud is provided with afair lead? 30; of any suitable type.

A. double reel comprisingthe singlereelSZ. and the single reel 34'. isoperatively mounted on the deck it. A base plate 36 for this reel assembly is formed. with. a projecting. portion. 38* The. reels 32 and. 34. are co-axially mounted, a large center bearing 411 comprising the main supporting. membar for; both. reels, the crank handle 42 being. directly connected with the reel 32', and the crank handle 44 being connected by means of the shaft 46,

pulleys

48 and 50, a belt 52 entrained on these pulleys, to drive the reel 34 which is directly secured to the shaft 54 on which the pulley 50 is mounted. The exact construction of this reel is immaterial in the present disclosure, but such reel assembly will normally include collars 56 to retain the reels in position on the

shafts

58 and 54, bearings 60 for the shaft 46, and the necessary complement of equipment to properly secure the reel assembly to the deck l6 and provide for the selective actuation of the

reels

32 and 34 by the hand cranks 42 and 44, respectively.

A cable 62 is terminally secured to the reel 34 and is guided by the

vertical rolls

64 and 66, and a horizontal roll 68, to enter the top of the tube 32 the other end of this cable 62 being secured, as at to the spud 26 adjacent the lower end 28 thereof. It will be understood that the tube is of a diameter considerably in excess of the diameter of the spud 26 and that the spud and cable 62 may freely slide within the tube. The

rolls

64 and 66 will ordinarily be secured by their vertical shafts 72, to the deck l6, and the roll 68 is shown secured to the top flange 24 of the tube 26, by means of terminal bearings 74.

The shore line 16 is terminally secured to the reel 32 and is threaded through the fair leads 30, to extend shoreward for securement to the material to be salvaged, suitable grappling or attaching means being provided on the terminal of said cable, to facilitate the securement of the salvage material. The fair leads 36 may comprise a horizontal roller 18 and a pair of vertical rollers 80, and it will be understood that suitable plate attachment means 82 will be provided on the upper end of the spud 26.

The operation of this invention will be clear 1 understood from the foregoing description of the mechanical details thereof, taken in connection with the above recitation of the objects sought to be achieved by this invention, but it ma be expedient to further illustrate the operation of this invention by reference to the use thereof in salvaging logs set adrift from booms during transportation of these log booms along river and coastal routes. These logs are, of course, of considerable value and a salvage boat of the general character illustrated in Figure 1 is used to salvage those logs after the same have become beached and the work is expedited and facilitated by the use of this invention. The boat is made to approach reasonably close to the shore and the hand crank 64 is turned to allow the reel 34 to unwind the cable 62 and thus allow the spud 26 to gravitate downwardly through the tube 28 until the lower end 28 of the spud contacts a submarine portion of the shore l2, all as indicated in Figure 1. One end of the shore line 16 is thrown ashore and secured to the log it and the hand crank 42 is used to wind the reel 32 and the cable 76 is tensioned, this action causing the spud 26 to be forced more deeply into the material of the beach, more securely anchoring the boat, and completely preventing the boat from being drawn shoreward when suilicient tension is placed on the shore line 16 to draw the log 16 away from the shore and eventually on to the deck E6 or into a boom of salvage logs. If no other logs are to be salvaged in the immediate vicinity, the reel 3 is actuated in the opposite direction to tension the cable 62 and to retract upwardly the spud 26, and when the spud has been sufficient- 4 1y released the boat is once again free to be maneuvered into a new position.

It should be clearly understood that the exact construction and proportionment of the various elements of this invention, as for example the positioning and form of the

rollers

64 and 66, the fair lead 30, and the particular mechanical combination of the

reels

32 and 34, is described in this application with a view to illustrating rather than limiting the particular constructon by which this invention may be reduced to practice. Therefore, though there has been shown a particular embodiment of this invention, this application is not limited to this particular embodiment, but it is desired to include in the scope of this invention the constructon, combination and arrangement of parts and portions substantially as set forth in the appended claims.

What is claimed as new and desired to be secured by Letters Patent is:

1. In combination in a salvaging boat, a tube extending substantially vertically through one end of a boat, a spud slidably mounted within said tube, a fair lead on the upper portion of said spud, a reel operatively mounted on said boat beneath the level of said fair lead, and'a shore line threaded through said fair lead and terminally connected to said reel, whereby the spud is forced downwardly when the shore line is terminally secured as to a beached log and the reel operated.

2. In combination with a boat, a tube extending substantially vertically through one end of a boat, a spud slidably mounted within said tube, a fair lead on the upper portion of said spud, a reel operatively mounted on said boat beneath the level of said fair lead, a shore line threaded through said fair lead and terminally connected to said reel, whereby the spud is forced downwardly when the shore line is secured ashore and the reel actuated, and a second cable secured to said spud adjacent the lower end thereof and extending upwardly through said tube, whereby the spud may be raised.
