June 30, 1953 F. w. HUCK BOAT ANCHOR Filed March 26. 1952 www Patented June 30, 1953 Vree stares er] entre 1 claim. l

This invention relates to boat anchors.

The primary object of my invention is to provide an anchor whereby a boat may be securely held in fast water below a dam or in currents of varying degree or strength, while fishing, but may be released without pulling against the current, by the same rope that holds the boat in place.

A further object of my invention is to provide an anchor in which a coil spring is used and adjusted at the proper tension, whereby the anchor will not trip by the pull of the boat, but may be released by a hard jerk on the rope fastened to the boat.

A still further object of my invention is to provide a boat anchor of the character specied that is simple and economical in construction and highly efficient and durable in use.

With the foregoing and other objects in view that will appear as the nature of my invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts illustrated in the accompanying drawings and more particularly pointed out in the appended claim.

In the accompanying drawings, which are for illustrative purposes only and are therefore not drawn to scale:

Figure 1 is a side elevation, illustrating the application of my invention.

Figure 2 is an enlarged longitudinal section, with parts broken away.

Figure 3 is a vertical transverse section, taken on line 3 3 of Figure 2; Figure 4 is a similar view, taken on line i-d of Figure 2 and Figure 5 is a similar View taken on line 5-*5 of Figure 2.

Referring to the drawings for a more particular description of my invention, and in which drawings like parts are designated by like reference characters throughout the several views, my boat anchor essentially comprises the relatively long upper shaft I, and the shorter shaft 2 at the lower or anchor end of the device.

The inner end of the shaft 2 is formed with an exteriorly threaded stem 3, for screw threaded engagement with the sleeve li, and the inner end of the shaft I with an exteriorly threaded stem 5 for screw threaded engagement with a second sleeve 6. outer end of the sleeve yS and formed with upper and lower lugs S and IS to engage corresponding openings II and I2 formed in said sleeve and other laterally extending lugs I3 and Ill to engage corresponding openings in the straps I5 and IB A square block 'I is positioned in the I formed at the inner end of the stem 3 of shaft 2. A circular concave disc I'I is carried by the lower exteriorly threaded end I8 of the shaft 2 and held in place by the inner and outer nuts I 9 and 20, respectively. The concave disc I'I is preferably fifteen inches in diameter, with a maximum depth or curvature of one and one-half inches, although it is to be understood that I do not limit myself to these particular dimensions. A. tubular housing 2| fits over the universal joint and associated parts, with one end. of said tubular housing bearing against the nut I9 and the opposite end thereof bearing against the collar 22 tting on the sleeve 23, carried by the smooth inner end 2i of the longer shaft I.

A coil expansion spring 25 encircles the upper portion ofthe shaft I, with one end bearing against the sleeve 23 and its opposite end bearing against a nut 26 screwing on the upper threaded end 21 of said shaft. The tension of the coil spring 2li may be adjusted by means of the nut 26 to hold the anchor end of the device against releasing in currents of varying strength or on windy days. A collar 28 also screws on the threaded end 2I of the shaft I and is providedY with a right-angularly bent loop 29 to receive one end, as 30, of the rope A that holds the boat. The

other end, as 3|, of the rope, is fastened to a.

loop 32 soldered or other fastened to the inner end of the tubular housing 2 I.

In practice, the anchor may be released by the rope A that holds the boat, without pulling against the current, simply by giving the rope a quick hard jerk. This causes the tubular housing 2l to slide upwardly and compresses the coil expansion spring 25, which exerts a thrust against the nut 25 on the upper threaded end 2'! of the shaft I, and since the shaft I is connected by means of a universal joint with the shaft 2, a pull is transmitted to the latter, which carries the circular concave disc I1.

- From the foregoing description taken in connection with the drawings, it is though that the construction, operation and advantages of my invention will be readily understood, without requiring a more extended explanation.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

A boat anchor of the character specied, comprising a relatively long upper shaft, a shorter lower shaft, a concave disc carried by the outer end of the lower shaft, a universal joint between the adjacent inner ends of the longer and shorter shafts, a tubular housing for said universal joint and associated parts, a loop carried by the upper n end of said tubular housing, a rope attached at one end to said loop, a colla-r carried by the lower end of the longer shaft and fitting against the corresponding end of the tubular housing, a Y

sleeve slidably mounted on the longer shaft and co-acting with said collar, a coil expansion spring encircling the longer shaft with one end bearing;r against said sleeve, a nut screwed on the upper end of said longer shaft for regulating the tension of said expansion spring and a collar screwed on said longer shaft and formed with a right-angularly bent loop through which said rope passes before connected to the boat.
