April 19, 1932. o CARLSON BOAT HANDLING APPARATUS Original Filed Jan. 22, 1929 Patented Apr. 19, 1932 OTTO CARLSON, OF ASTORIA, OREGON BOAT HANDLING APPARATUS Application filed January 22, 1929, Serial No. 334,288. Renewed September 18, 1931 My invention relates to apparatus for lowering or raising boats, such as life boats, from a ship.

In accordance with my invention, apparatus is provided, which may be employed to lower a boat, such as a life boat, from a ship. When the boat being lowered rests upon the water, the boat is automatically disconnected from the lowering unit. In the event that either the bow or stern should first engage the water, and hence the automatic releasing action be impaired or prevented, such action may be manually effected by the operator within the boat. The apparatus is of simple construction, strong and durable.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of apparatus embodying my invention,

Figure 2-is a transverse section taken on line 22 of Figure 1,

Figure 3 is an enlarged side elevation of one of the releasing hooks,

Figure 4 is an edge elevation of the same,

Figure 5 is a side elevation of a modified form of releasing hook, and,

Figure 6 is an edge elevation of the same.

In the drawings, wherein for the purpose of illustration, are shown preferred embodiments of my invention, attention being called first to Figures 1 to 4, inclusive, the numeral 10 designates a boat, such as a life boat, having a keel 11.

The hoisting or lowering unit embodies a rod 12, which may be square in cross section, round, or of any other suitable shape. I prefer to mount sheaves 13 directly upon the rod 12 and the pulleys in these sheaves are engaged by tackle ropes let, which are at tached to the blocks upon the davits, as is well known.

Arranged within the boat 10 are stanchions or uprights 15, each of which is preferably formed of a pair of strap irons 16, bolted or riveted together, as shown at 17. The lower ends of these strap irons are apertured to receive a bolt 18, also passing through openthe hooks are freed ings in a generally U-shaped strap 19, which ispassed about the keel 11.

The stanchionor upright 15, may remain permanently vertical or may be folded downwardly to a horizontal position, when not in use, The stanchion 15 tothe left, Figure 1, may be retained permanently vertical by means of a strap 20, passing about the same, and attached to a .seat 21, or other fixed part of the boat. The stanchion 15 to the right, Figure 1, may be swung downwardly upon the pivot 18, when not in use, and when this is desired the strap 20 is omitted, and the 1 stanchion operates between a pair of seg-- mental guides 22. V

The'strap'irons 16, attheir tops, are bent laterally or spread, affording spaced arms 23. These spaced arms carry outwardly projecting lower stationary hooks 24, Figure 3, equipped with resilient extensions 25, attached thereto. Arranged above the stationary hooks 24 are pivoted hooks 26, carrying depending resilient extensions 27. The hooks 26 are formedtintegral with a rock shaft 28, which is rotatably mounted within open ngs 29, in the spaced arms 23. The upper hooks 26 normally depend, and are in alignment with the hooks 24. The upper and lower hooks with their resilient extensions 25 and 27 provide sockets for receiving and holding the rod 12.

' Arranged between the upper ends of the arms 23 are weights 30, rigidly mounted upon the rock shaft 28, and sufficiently heavy to overcome the weight of the hooks 26, when w from engagement with the rod 12.

These weights are provided in their lower ends with apertures for receiving and attaching a cord or cable 31, passed about pulleys 32. The cord extends longitudinally of the boat adjacent to the keel. pulling the cord,fthe weights 30 may be swung downwardly, and the hooks 26 manually turned to the upper position, thereby releasing the, rod 12. In Figures. 5 and 6, I have shown a modification of the attaching unit or stanchion. The stanchion or' upright in these figures embody a pair'of strap irons 33, having the spread or spaced arms 34. The arms 34 carry outwardly projecting fingers 35, equipped with upstanding resilient extensions 36. Co-acting with the lower fingers 35 are upper stationary fingers 37, carrying resilent extensions 38. Arranged above the fingers or extensions 37 are pivoted hooks 39, carried by a rock shaft 40, pivoted within openings in the upper ends of the arms 34.

A weight 41 is rigidly attached to the rock 7 shaft 40, and is arranged between the arms 34. The weight 41 is heavier than the hooks 39 and will raise the hooks, when they are freed from engagement with the rod 12. The numeral 42 designates a cord or cable, attached to the weights 40, and corresponding to the cord or cable 31.

In the operation of the first form of the invention, as shown inFigures 1 to 4, inclusive, the rod 12 is arranged within the sockets beneath the depending pivoted hooks 26. As the weight of the boat is now carried by the hooks 26, the weights 30 can not turn these hooks upwardly. The boat may now be lowered in the usual manner, and if it strikes the water, at a level, the rod 12 will move downwardly and relieve the engagement between the rod Y12 and the hooks 26. The weights 30 will now automatically swing downwardly, swinging the hooks 26 upwardly and the rod 12 will be disengaged from the hooks. Should either the bow or stern first engage the water, and it is desired to release the boat, the operator within the boat pulls the line 31, thereby manually turning the weights 3O downwardly and raising the hooks 26. This form of apparatus may be used in both raising and lowering the boat.

In Figure 5, the operation of the pivoted hooks 39 is the same as that of the hooks 26. The fingers or extensions 35 and 37 provide separate means for raising or otherwise handling the boat, when it is not desired to use the pivoted hooks 39.

It is to be understood that the forms of my invention, herewith shown and described, are to be taken as preferred examples of the same, and that various changes in the shape, size and arrangement of parts, may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claims.

Having thus described my invention, I claim 1. In a boat handling apparatus, a stanchion embodying a pair of strips secured together and spread at their ends for producing spaced arms, a rock shaft pivotally mounted upon the spaced arms and carrying hooks arranged upon opposite sides of said .arms, a weight arranged between the arms and rigidly mounted upon the rock shaft, and lateral extensions carried by said arms and co-acting with said hooks for producing sockets for the reception of rods or the like.

connected with the rock shaft, and lateral ex- 5 tensions carried by the arms and co-acting with the hooks to produce sockets for receiving rods or the like.

In testimony whereof I aflix my signature.

OTTO OARLSON.
