page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
My invention relates to that class of anchors having a sliding stock adapted to
lie parallel with the shank when the anchor is not in use.
In anchors of this description as heretofore constructed, the sliding stock is held
in place in a central position at right angles to the shank when the anchor is to be
used, by a pin or key passing through a hole or slot in the stock, which prevents it
from moving longitudinally in one direction, while a collar or shoulder on the stock
adapted to bear on the side of the shank opposite to that on which the pin or key
is located, prevents any longitudinal movement in the opposite direction.
This method of fastening the stock is however objectionable, as the pin or key is
liable to drop or work out of its hole or slot when the anchor is on the bottom and
thus allow the stock to slide out of place into a position parallel with the shank
when the anchor is liable to turn over in such a manner that its flukes will fail to
properly catch and hold at the bottom as required. Furthermore the pin or key is
often lost, thus rendering the anchor temporarily useless.
My invention has for its object to overcome these difficulties and to provide a
more secure and reliable fastening for holding the stock in place at right angles to
the shank, whereby all liability of its becoming loose and slipping out of place is
avoided. To this end my invention consists in providing the stock, at or about the
centre of its length, with a screw-thread which is adapted to engage a nut or a
corresponding thread formed on the inside of the eye of the shank through which
the stock slides, by which construction the stock is held securely in operative
position, and all liability of its becoming displaced when the anchor is on the
bottom, entirely avoided."
In the accompanying drawing:-
Figure 1 is a perspective view of an anchor constructed in accordance with this
invention, the stock being shown in the position which it occupies when the anchor
is on the bottom,

of the shank in the position which it occupies when the anchor is not in use.
Figures 4 and 5 are modifications to be referred to.
In the said drawings A represents the shank of the anchor, and B, B, the flukes,
which are preferably made of the form shown without shoulders at the bottom,
whereby the fouling of the cable is prevented.
use.
C is the stock which is adapted to slide through the eye b at the upper end of
the shank A and, as usual, lie parallel with said shank when the anchor is not in
The stock C is provided at or near the centre of its length with a screw-
thread d, on one side of which is the usual collar or shoulder e, which, when the
stock is in a position at right angles to the shank, as seen in Figures 1 and 2, bears
upon the said shank around the eye b. On the opposite side of the shank, the
stock is encircled by a thumb-nut D, which slides loosely upon the smooth portion
thereof and engages with the thread d, whereby the shoulder or collar e is drawn
up tightly against the shank, and the stock is thus securely confined in place and
cannot by any possibility become loose or slide out of position when on the
bottom, thus causing the flukes of the anchor to take hold of the ground at all
times as required.
After the anchor is hauled aboard, the nut D is unscrewed and slipped back on
the smooth portion of the stock, when the latter can be slid through the eye b and
turned down parallel with the shank as seen in Figure 3.
If desired the nut D may be dispensed with, and the eye b provided on the
inside with a screw thread f, as seen in Figure 4, in which case the thread d will
engage with the thread f, the stock being turned until the collar or shoulder c is
brought to a firm bearing against the side of the shank A; or if preferred both the
nut D and the collar or shoulder e may be dispensed with, as seen in Figure 5, in
which case the stock may be screwed in from either side, and may have both
ends g curved to enable it to be placed parallel with the shank on either side
thereof; I however regard these slight differences of construction as mere
modifications of my invention, either of which may be adopted as preferred.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, as communicated to
me by my Foreign Correspondent, I declare that what I claim is :-
First. An improved anchor-stock provided with a screw-thread for securing the
stock in operative position upon the anchor-shank, substantially as described.
Second. The combination with an anchor of the kind berein described, of a
sliding anchor-stock having a screw threaded portion to secure said stock to the
auchor-shank in operative position, substantially as described.
