United States Patent- DEVICE FOR THROWING AND HOISTING AN ANCHOR The present device relates to a device for throwing and hoisting boat anchors.

One of the objects of the present invention is to provide a device which may be mounted on the deck of a boat which may be remotely controlled to throw the anchor from the boat into a launching position.

Another object of the invention is to provide a device which will not only permit the remote control. of the launching of the anchor but also provide for the anchor to be hoisted from a remote point. l

A still further important object of the invention is to provide a novel anchor receiving head which is of such a construction that the pin of the anchor is guided therein from its different swinging movements and then securely held in position therein on the deck of the boat.

The accompanying drawings and-;the specification, as well as the claimed subject matter, disclose the invention as preferred and embodied at this time for under standing the problems sought to be solved in boat anchor throwing and hoisting devices. Since the teachings herein may suggest changes to others who wish to avail themselves of the benefit of the invention, it will be appreciated that subsequent modifications hereof may well be equivalent in form and hence the same in spirit and principle as this disclosure.

In the accompanying drawings, wherein for the purpose of illustration there is shown a preferred embodiment of the invention: a

Fig. 1 is a top plan view;

Fig. 2 is a side elevational view of the front portion of a boat showing the anchor throwing and hoisting device in its normal raised inoperative position on the deck of the boat; 7

Fig. 3 is a side elevational view of the front portion of a boat illustrating the device in its released upper position of throwing or launching the anchor;

Fig. 4 is a fragmentary front elevational view of the bow of a boat showing the device in its lower position on the deck thereof in anchor hoisted position;

Fig. 5 is a detail side elevational view of the anchor receiving head;

Fig. 6 is a detail front elevational view of the anchor receiving head; and I Fig. 7 is a perspective view of the anchor receiving head and the upper pin carrying end of the anchor which is guided into the head; the pin being received in the slot in the head.

In the accompanying drawings wherein for the purpose of illustration there is shown a preferred embodi ment of the invention and in which corresponding parts are designated by similar reference characters, Fig. 1 generally shows the anchor throwing and hoisting device The device includes a pair of spaced supports 12 and 14 secured to the deck 8 of the boat longitudinally and centrally thereof and in somewhat spaced relation from the extreme front end portion of the bow and forming V 2 v a base. The deck of the boat has an elongated longi tudinally extending recess therein in registry with the space formed between the supports 12 and 14 into which the anchor support 16 is received.

The movement of the anchor support 16 is efiected by means of a pair of operating supporting legs 18 and 20. One end of the'operating leg 18 is pivotally connected at 22 between the supports 12 and 14 of the base at the front, portions thereof and the other end of this leg is pivotally connected by-hinge means 24 to the under side of the anchor 16 adjacent the front end and on the underneath side thereof.

As clearly illustrated in Fig. 3 the other leg 20 is hingedly connected at its upper end to the underneath side of the anchor support 16 inwardly of the end thereof and the other end portion of this leg is pivotally connected at 28 for vertical swinging movement to the inside of the boat below the deck. The point of pivotal connection 28 of the lower portion of the leg 20 inside of the forward portion of the boat is such to permit as illustrated in Fig. 1, the anchor support 16 in its inoperative position to assume a vertical position where .the leg 18 is in its rearward horizontal position with in its normal raised inoperative position on the deck 8 'fo'f a boat 10. I

respect to the boat deck and as shown in Fig. 4 the anchor support 16 to assume a horizontal anchor hoisting position with respect to the boat deck when the leg 18 is in its forward horizontal position with respect to the deck of the boat. p

One end of a coiled spring 30 is pivotally connected in any manner to the inside of the forward portion of the boat and has its other end connected to an integral ear 32 on the leg 20 arranged substantially midway of the free ends thereof.

As shown in Fig. 2, the spring 30 is completely loaded when the anchor support 16 is in-its vertical inoperative position and substantially unloaded when the anchor support 16 is in its horizontal hoisting position.

The anchor support 16- is substantially of square vertical cross section and is hollow throughout'its entire length. To the inner end there is securely fastened by means of bolts or the like a cap 36 having a pulley 38 rotatably mounted therein; A similar end cap 40 having a pulley 42 is securely fastened to the other forward end of the anchor support 16. I e

A novelly constructed hollow anchor receiving head 46 is secured within and at a right angle to the cap 40. It will be observed as shown in Figures 5, 6 and 7 that the wall of the depending free end of the head 46 is provided with oppositely disposed slots 48 therein for receiving the horizontally projecting pins 50 on the end of the anchor 52. Y

The pins 50 are directed into the slots 48 by. means of the outwardly tapered spaced cars 54 and 56 defining substantially inverted opposite V-shaped guide openings; in the wall of the head which merge with the slots 48.

It is to be noted that the free'ends of the ears 54 and 56 are somewhat pointed and one terminates short of 7 It has been found that the novel constructionof the ears, and slot arrangement with respect thereto accurately and positively guides the anchor pins into theslots not withstanding the usual twisting and swaying of the anchor generally incident to the hoisting thereof.

The anchor arm 60 is provided with a hole 62 in the free end thereof to which one end of the anchor rope tion, an anchor having its arm received in the anchor head, resilient means secured to one of the legs and to the boat normally urging the anchor support from its vertical inoperative position, through the anchor throwing arc, to its horizontal anchor hoisting position, and a control rope-connected to the anchor arm and trained around pulleys on the anchor support and into the boat for controlling the operation of the anchor support and the throwing and hoisting of the anchor.

8. An anchor head for receiving'the arm of an anchor having oppositely extending pins thereon, comprising a tubular member, one end thereof terminating in a pair of spaced substantially V-shaped pointed ears with the side portions thereof defining inverted V-shaped openings, said openings merging into diametrically opposed l5 longitudinal anchor pin receiving slots in the wall of the tubular member, the side walls of each of the V-shaped pointed ears taperingjtoward their apex and slanting inwardly of the tubular member thereof, one of the pointed ears being shorter than the other, and the arcuate distance from the point of one ear to the point of the other on one side being substantially 160, and the arcuate distance therearound on the other side being substantially 200. 7
