1 Claim.
This invention relates to anchor construction, the primary object of the invention being to provide means for releasing the nukes, of the anchor from obstructions under which the nukes may be held, thereby preventing loss of the anchor which frequently occurs, when attempting to release fouled anchors of known construction by exerting excessive pull on the anchor.
An important object of the invention is to provide an anchor embodying a. shank, and a spindle on which the nukes are pivotally mounted, means being provided for releasably securing the nukes in their extended positions, so that when the anchor is dropped, the nukes will be embedded in the bed of the body of Water to anchor the boat with which the anchor is connected, in a predetermined position.
With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawing Figure 1 is an elevational View of an anchor constructed in accordance with the invention.
Figure 2 is a sectional view through the anchor spindle and nuke mounting.
Figure 3 is a sectional View through the spindle and nuke mounting, illustrating the spring tensioning means to regulate the action of the nukes and adapting the anchor for use under various conditions.
Referring to the drawing in detail, the anchor comprises the shank 5 which is formed with a hollow head 6 through which the nuke spindle 1 extends, the spindle 'I being secured within the hollow head, in any desired manner.
The nukes 8, are formed with bearing portions 9 which are secured to the hollow shaft I0 disposed between the bearing portions 9 and the spindle l, the hollow shaft being formed with a cut-out portion II disposed at a point intermediate the ends thereof, the cut-out portion Il falling opposite to the opening I2 formed in the hollow head 6.
Secured to the shank 5 of the anchor, is a leaf spring I3, which spring is formed with a curved end I4 presenting a lug I5 adapted to ride in the opening I2 and cut-out portion Il, the lug I5 being designed to engage the edges of the cutout portion Il, to restrict rotary movement of the nukes with respect to the fluke spindle 1.
The spring I3 is provided with an opening to receive the securing bolt I6 which passes through an opening in the shank 5 of the anchor. The
spring I3 is further held in position by means of the plate I1 and adjusting plate I8, the plates I1 and I8 having openings adapted to aline to receive the bolt I6. Thus, it will be seen that the adjustment of the plates I'I and I8, will tend to regulate the tension of the spring I3 so that the nukes may be adjusted for use in securing a boat under various conditions. That is to say, if the anchor is to be used in rough weather, to hold the boat, the tension on the spring would be increased, but under normal conditions, the tension of the spring would be adjusted so that the anchor would hold the boat against drifting, but the anchor would be released upon an excessive pull directed to the anchor.
Assuming that the nukes of the anchor are extended in a manner as shown by Figure 3 of the drawing, and the nukes are caught under a rock or lug. It is obvious that an excessive pull on the anchor, will cause the spring lug I5 to ride over the shoulder presented at one side of the cut-out portion of the hollow shaft, permitting the nukes to move to a position at such an angle with respect to the shank of the anchor, as to cause the nukes to ride from under the material holding the nukes against movement.
From the foregoing, it is believed that the construction and operation of the anchor forming the subject matter of this invention, will be clear, and that further detail disclosure as to the use and operation of the anchor is unnecessary.
What is claimed is:
In an anchor, a shank, a shaft mounted for rotary movement at one end of the shank, nukes secured to the shaft, a spring arm secured to the shank, one end of the arm being curved providing a lug adapted to engage the shaft, normally restricting movement of the shaft and nukes mounted thereon, a plate engaging the spring arm adapted to secure the spring arm to the shank, and means for adjusting the plate longitudinally of the shank towards and away from the lug, whereby the tension of the spring arm is regulated, regulating the movements of the shaft and nukes.
