IMPROVEMENTS IN THE CONSTRUCTION OF ANCHORS
Year: 1885

page_text: I, WILLIAM WASTENEYS SMITH of the City & County of Newcastle-on-Tyne
Civil & Consulting Engineer do hereby declare the nature of the said invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF ANCHORS" to be as follows:-
This Invention has for its object improvements in the construction and reducing
the cost of manufacture of my well known "Stockless" Anchors as described in
Letters Patent granted to me 2nd day of March 1871 N° 552 and 12th day of
December 1874 N° 4281.
For this purpose I form the crosshead and the two arms, each arm fitted with
horns, in one solid piece by preference (although; same end can be obtained by
making them in two or more parts so long as these parts are rigidly secured
together) about the centre of the crosshead I make an elongated slot into which
is secured the shank by a pin or pivots, the slot being sufficiently long to adinit of
the arms and crosshead vibrating freely on the shank to an angle of about 42°
each way before coming in contact with its extremities which form the required
stops.
The shank may be of the most simple shape, either slightly tapered every way,
parallel from end to end, or fluted on its sides.
In some instances I use a bifurcated shank in which case two slots are formed in
the crosshead instead of one.
For purpose of reducing weight and having a uniform thickness of material
I hollow out the space at the back of the arms between the horns as also that at
the back of the crosshead these recesses enabling the pin or pivots which secure
the shank to the crosshead and arms to be inserted.

Civil and Consulting Engineer do hereby declare the nature of this invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF ANCHORS" and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This Invention has for its object improvements in the construction and reduction
of cost of manufacture of my well known "Stockless" Anchors as described in
Letters Patent granted to me 2nd day of March 1871 N° 552 and 12th day of
December 1874 No. 4281.
For this purpose I form the crosshead and arms in one piece (although same end
may be gained by making them in any number of parts so long as they are rigidly
joined together) about the centre of the crosshead is formed an elongated slot in
which the shank is inserted and secured by a pin or pivots and is sufficiently long
to admit the arms to vibrate on the shank to an angle of about 42° each way
before coming in contact with its extremities which form the required stops.
The shank may be of the simplest shape of any convenient section, longitudinally
fish bellied, tapered or parallel and either internally hollow or fluted on its sides.
In some instances I use a bifurcated shank in which case two slots are made in
the crosshead instead of one.
For purpose of reducing weight and having a uniform thickness of material
throughout the arms are hollowed or recessed between the horns and the resisting
surfaces of them are made concave. The crosshead is also recessed for same purpose
and for admitting the insertion of the pin or pivots for securing the shank.
In the accompanying drawings
Figure 1. is a plan of an anchor.
Figure 2. a side elevation showing arms at full angle one way, and
Figure 3. is an end view.
The shank A is secured to the crosshead B by the pin or pivots g, the arms C
are integral with the crosshead and are formed with concave surfaces similar to as
shown in section in the plan view, and have palms h. h. and horns d. d. at the bee!
for the purpose of causing the points of the arms to enter the ground, both the
arms and crosshead are recessed as shown in dotted lines in Figures 1 and 2. and
open in Figure 3, but it is obvious these recesses can be very much varied opening
either to sides of arms or front of crosshead or otherwise but still serving same
purpose; the crosshead B has a slot i. in centre of it with opening through at back
to allow sand or mud to escape, within this slot the shank A is secured by the pin
or pivots g. and allowed freedom of movement within an angle of about 42° either
way before coming in contact with the stops.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
An anchor having a shank A. pivotted with a crosshead B. integral with the
arms C, which are formed with the horns d. d. palms h. h. and concave resisting
surfaces, both crosshead and arms being hollowed or recessed substantially as, and
for the purpose set forth.
