4 Claims.
'This invention relates to a collapsible anchor, the general object of the invention being to provide means whereby both the flukes and the stock can be collapsed so that the anchor will occupy but little space when not in use and which can b e collapsed when in use so that it can be readily lifted without danger of fouling This invention also consistsin certain other features of construction and in the combination 0 and arrangement of several parts, to be hereinafter `fully described; illustrated in the accompanying drawings'and specically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:
Fig. 1 is a longitudinal sectional view through the anchor.
Fig. 2 is a section on line 2-2 of Fig. 1.
Fig. 3 is an elevation.
Fig. 4 is a view taken at right angles to Fig. 3 and showing the lower part in section.
Fig. 5 is a section on line 5-5 of Fig. 4.
Fig. 6 is a view of the lower part of the shank and showing how the ring is slidably arranged thereon.
Fig. 7 is a perspective view of one of the guards.
In these drawings, the numeral I indicates the shank of the anchor which has its lower end reduced and of forked construction, the prongs of this forked part being shown at 2. Each prong has a longitudinally extending slot 3 therein and the lower portion of the shank is formed with the lower large chamber 4 which opens out into the space between said prongs and with a smaller upper chamber 5 which opens out into the top of the chamber 4, a bore 6 extending from the top of the upper chamber 5 into a chamber l formed in an enlarged part of the top of the shank. The pair of lukes is shown at 8 and the inner end of each fluke has an upright head 9 thereon which is of forked shape with the space between the prongs tapering inwardly as shown in Fig. l.
These heads overlap and a pivot pin I0 passes through the heads where they join the flukes and through the lower ends oi the prongs, the holes in the prongs for this pin being shown at II in Fig. 6 and this pin also passes through the lower end of a pair of channel-shaped guards I2 which provide a space between themselves and the prongs 2 for a sliding collar I3 which carries a pin I4 which passes through the slots 3 in the prongs and also through a wedge member I5 which is slidably arranged in the chamber 4 and is adapted to engage the wedge-shaped spaces formed by the prongs of the heads 9 to hold the flukes in operative position. A rod or cable I6 has one end attached to the wedge-shaped member I5 and said rod or cable passes through the 5 chambers 4 and 5 and through the bore 6 and through the upper chamber 1 and through a hole in the top wall of the chamber 1, a ring I1 being attached to the upper end of the rod or cable.
A spring I8 is coiled around a part of the rod 1 or cable and is located in the chambers 4 and 5 and tends to press the wedge-shaped member downwardly. As will be seen when the wedgeshaped member is in its lowermost position, it will engage the wedge-shaped spaces formed by the prongs of the heads 9 of the nukes and as the collar I3 is connected with the wedge-shaped member I5 by the pin.l4, this collar will also be moved downwardly so as to fit around the heads 9 and thus the iiukes are locked in operative position as shown in Figs. 1 and 3. The guards I2 protect the collar I3 and a slot I2' is formed in each guard for permitting escape of any water collecting in the spaces between the guards and the lower part of the shank. These guards are 25 connected with the shank at their upper ends as shown at I9 in Figs. 3 and 4. Thus, it will be seen that by pulling upwardly upon the cable or rod I6, the wedge-shaped member I5 and the collar I3 are raised so as to release the heads 9 of the flukes 8 so that these flukes can drop into the dotted line position shown in Fig. 1 which will enable the anchor to be readily lifted and eliminate fouling of the anchor.
We also provide means for collapsing the 35 stock 20 by making the stock in two sections with the inner ends of the sections provided with heads 2|, each head having a tapered recess 22 therein for receiving a wedge-shaped member 23 slidably arranged in the chamber 'l and con- 40 nected by upper and lower collars 24 with the cable or rod I6. The wedge-shaped member has a pin 25 passing therethrough, the ends of which enter elongated slots 26 in the enlarged upper end of the shank and each head 2| of the stock is pivoted in the lower part of the chamber 1 by a pin 26. Thus when the rod or cable I6 is moved downwardly by the spring I8 to lock the flukes in operative position, the wedge-shaped member 23 is moved downwardly to lock the sec- 50 tions of the stock in operative position but when the cable or rod IB is moved upwardly, the wedgeshaped member is moved upwardly so that the sections of the stock can move to the dotted line position shown in Fig. 2 while the flukes end-of the shank to receive the anchor chain and the outer end of each iiuke is of the substantially triangular shape shown at 2l in Fig. 2 and provided with the points 3l at its front. This end of the iiuke insures the anchor against dragging on almost any sort of a bottom.
-It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement .of the several parts, .provided that such changes fall within the scope of the v appended claims.
