Ancient Greek seamen used these early anchors to put in for trade at the mouth of the Nile. The invention of the steam hammer in made the welding of heavy masses of iron a comparatively easy and reliable process, so that from this time onward the strength of anchors fully kept pace with that of the chain cables which had come into general use.

Rodger's anchor marked a great departure from the form of previous anchors. The arms were formed in one piece, and were pivoted at the crown on a bolt passing through the forked shank. The points or pees to the palms were blunt.
This anchor had an excellent reputation amongst nautical men of that period, and by the committee on anchors, appointed by the British admiralty in , it was placed second only to the anchor of Trotman. Later came the self-canting and close-stowing Martin anchor, which, passing through successive improvements, became the improved Martin anchor made of forged iron.
A projection in the center of the arms works in a recess at the hub of the shank; the vacancies outside the shank are filled by blocks bolted through on each side, and are flush with the side plates, which keep the flukes in position.
The introduction of cast steel in led to the improved Martin-Adelphi pattern, in which the crown and arms are cast in one, and, with the stock, are made of cast steel, the shank remaining of forged iron. A projection in the crown works in a recess right image , and is secured in its place by a forged steel pin, fitted with a nut and washer, which passes through the crown and the heel of the shank.
All of the above anchors were provide with a stock, the use of which is to "cant" the anchor. If it falls on the ground, resting on one arm and one stock, when a strain is brought on the cable, the stock cants the anchor, causing the arms to lie at a downward angle to the holding ground; and the pees enter and bury themselves below the surface of the soil.
Stockless anchors have been extensively used in the British mercantile marine and in some other navies. In they were adopted generally for the British Navy, after extensive anchor trials, begun in Their advantages are: handiness combined with a saving of time and labor; absence of davits, anchor-beds, and other gear, with a resulting reduction in weight; and a clear forecastle for "right ahead" gun fire or for working ship.
On the other hand, a larger hawsepipe is required, and there appears to be a consensus that a stockless anchor, when "let go" does not hold so quickly as a stocked one, is more uncertain in its action over uneven ground, and is more liable to "come home" drag. At the beginning of the 20th century, the stockless anchors principally in use in the British navy were Hall's improved, Byer's, and Wasteneys Smith's.
In Hall's improved anchor, the arms and crown of cast steel are in one piece, and the shank of forged steel passes up through an aperture in the crown to which it is secured by two cross bolts. Two trunnions or lugs are forged to the lower end of the shank. Byer's plan, the flukes and crown consist of a steel-casting secured to a forged shank by a through bolt of mild steel, the axis of which is parallel to the points of the flukes; one end of the bolt has a head, but the other is screwed and fitted with a phosphor bronze nut to allow the bolt to be withdrawn for examination.
A palm is cast on each side of the crown to trip the flukes when the anchor is on the ground, and for bringing them snug against the ship's side when weighing. Wasteneys Smith's anchor is composed of three main parts, the shank and crown which form one forging, and the two flukes or arms which are separate castings.
A bolt passes through the crown of the anchor, connecting the flukes to it; to prevent the flukes working off the connecting through bolt, two smaller bolts pass through the flukes at right angles to the through bolt and are recessed half their diameter into it. Small boat anchors have developed a bit separately from the first half of the 20th century, with the advent of the "CQR" , developed by Geoffrey Ingram Taylor of Scotland in the early s. This design was not symmetrical, and required the use of a bow-roller design to effectively stow it.
This is practical for small boats and yachts, but does not scale in a practical manner for large shipping. The CQR is now manufactured by Lewmar. American Richard Danforth invented and developed the "Danforth" pattern in the s, a return to the symmetrical concept but with very large flat plate flukes.
This anchor offers very good holding power for its weight high efficiency but does not perform well in other respects, meaning that it is not a good general purpose anchor. The original Danforth is still manufactured and sold by Tie Down Engineering in the USA.
Peter Bruce of the Isle of Man in the UK developed the claw-type "Bruce" anchor in the s. Bruce Anchor Co has its primary role in the very large anchor business, producing mooring anchors and permanent installation types for heavy industry, such as oilrigs. On the back of this reputation, the Bruce small boat anchor type was initially very successful, and represented some significant improvements over the CQR.
It is no longer produced. New generation anchors have come into force since the latter part of the 20th century. The German "Buegelanker" features a simple single flat triangular fluke, with a roll-bar to ensure correct setting. A surprisingly simple design, this has proven more effective than its ancestors.
Frenchman Alain Poiraud developed the "Spade" anchor in the s, a huge leap in performance over any types which proceeded it. The Spade was the first anchor to successfully make use of a concave fluke, which provides the greatest efficiency as opposed to the convex "plow" type of the CQR, or the flat "plate" type of the Danforth.
The "Bulwagga" is essentially a modified fluke style anchor which made itself known at the very beginning of the s. Rather than two flukes in a symmetrical configuration, it adds a third for an equilateral triangular arrangement. This concept is an improvement over the Danforth in terms of general purpose usage, but is slightly comparatively inefficient on account of the fact that one fluke is always unused , and is difficult to stow.
New Zealander Peter Smith in the early s took elements of the Spade and other types, and developed unique solutions of his own, in order to design the "Rocna" anchor, a general purpose type which uses a concave fluke, a self-righting roll-bar, and setting skids. From Wikipedia, the free encyclopedia. Redirected from History of the Anchor. Greek coins of BC show anchors with rudimentary palms. An English anchor shaped from the fork of a yew-tree is ascribed to BC. A Cyrene iron anchor without palms, and inscribed with the ship's name, is attributed to about 50 BC.
Depictions of iron anchors of the time of King Herod, about 35 BC, show curious enlargements on the shanks believed to be carryovers from the times when cylindrical perforated stones were strung on wooden anchor-shanks, and also show palms on the arms.
Sculptures on the Arch of Tiberius, about 20 AD, show similar enlargements on the shank, but no palms. About 40 AD the ship of Emperor Caligua was equipped with a 16 foot iron tipped oaken anchor with a heavy leaden stock.
This was discovered intact when Lake Nemi, near Rome was drained in At the same time there was discovered, after years submersion, a wood-sheathed iron anchor weighing about pounds.
Distinguished by the fact that it had a portable stock, which was an invaluable convenience lost to the world until "invented" again some years later and finally adopted by the Admiralty in In AD St. Clement the fourth Pope, is said to have been thrown into the sea, tied to an anchor a method of execution not uncommon in those days.
From ancient times St. Clement has been the Patron Saint of Anchorsmiths, who formerly observed his Feast Day on the 23rd of November. Iron anchors are said to have been first forged in England East Anglia] in AD The Danish "Oseburg Anchor," about A. The medieval anchor of AD as depicted in a Bayeau tapestry looks almost modern.
The Statutes of Genoa of AD required a ton ship to carry 12 iron anchors of from to pounds each. A Florentine engraving of AD shows a two-piece wooden stock of the style popular for the following years. The "Sovereign of the Seas," tons, in carried 12 anchors of pounds each. In Sir Wm. Phipps in his attack on Quebec lost a thirteen-foot anchor, recovered in modern times]. Anchors of about had long shanks, straight arms at 50 degrees, sharp points at the crown, large diameter rings, and wooden stocks the length of the shank or longer.
An anchor of this style marked "" was reclaimed from the wreck of a gun ship sunk at Sheerness, England. In Reaumur issued in France the first public exposition of the science and art of anchor construction. In iron stocks began to emerge from the experimental stage, but the popular anchors of the period still had wooden stocks and relatively long shanks and straight arms. In and succeeding years Richard Pering of England greatly improved the quality of welds in anchors, shortened the shanks and put more curvature into the arms.
In Captain Hawke of the Royal Navy applied for an iron stocked anchor for his ship and was derided, but permitted the use of iron stocks in anchors of not over pounds. In Lieutenant Belcher of the Royal Navy introduced the tumbling fluke, later improved by Honibal and Porter.
With cantpalms added by Trotman, the anchor became quite popular. From onward some hundred different types of "improved" anchors were patented in rapid succession practically all regarded today as "freaks. In Pering adapted steam power to the operation of the heavy falling weights used in the welding of anchors. Rodgers introduced his "Patent Small-Palm Anchor and won considerable public favor.
The Royal Navy now began to concede the superiority of iron stocks. By the Hawkins patent tumbling fluke stockless anchor and developed to a form approximating that of most stockless anchors of today. By the Royal Navy completely surrendered to the iron stock and gave full sanction to the type of anchors now known as the "Admiralty" anchor.
This type of anchor, also known as "Old Style" or "Kedge" is no longer used for large ships but continues in use for small boats and for moorings.
Although it has great holding power in a penetrable bottom it is extremely awkward and the long stock is vulnerable to mechanical damage. When in position the upstanding arm may foul a chain or pierce the hull of a vessel. The "one" arm version is popular for moorings and is equipped with a second shackle for easier placement.
In a British Commission declared the Trotman anchor "Best". By the Mushroom type of anchor appeared as an instrument especially suited for permanent moorings. With the removal of the stock, from Mertom's anchor of and the advent of Lathem's anchor the use of stockless tumbling-fluke anchors increased rapidly.
In the ball-and-socket type of stockless anchor first appeared in England. In A. White stowed the stocks of "old style" anchors by sliding them down a shank designed with a quarter-twist. In C. Herreshoff constructed a four-piece de mountable old-style anchor for a time widely acclaimed by yachtsmen. By Baxter was stowing his Stockless Anchors in a hawse pipe. This innovation proved of utmost importance, for from that day forward, the Stockless Anchor increased in popularity until today it is practically the only type of anchor used on ships of real size.
American styles incline to be chunky, with comparatively broad and blunt flukes. The U. Navy's version has flukes somewhat longer and of greater area.
European anchors, in general, tend to more curvature and to smaller and sharper flukes. The stockless anchor used today, on ships of size that are likely to encounter any and all types of sea bottom, reflect the experience of mariners for the past twenty five hundred years in compromising between pure dead weight for very hard bottoms and on the other hand ability to bite and to hold well in soft bottoms.
The stockless anchor is ruggedly built, will handle and stow easily and readily disengage from sea-bottoms and submerged wreckage. Modern Ocean Anchor. With its concave wedge shape and single penetrating tip, the Spade anchor is simplicity itself, yet its proven effectiveness is far from coincidence. It is available in galvanized steel, marine grade aluminium or stainless steel and by simply removing one non-load bearing bolt the shaft removes for easy stowage. In the attempt to successfully stow stocked anchors in hawsepipe, in Tyzack revived and ancient practice of placing a stock through or near the head of the anchor, instead of at the shackle end, as in Western custom.
Examples of this type are the Tyzack anchor, the Hartness anchor , the Brown anchor , the Hein anchor , the Croseck anchor and the Danforth anchor This particular type of anchor is somewhat modified by Mr. Shipley of the U. These "head stocked" anchors have the advantage of high holding power, in proportion to weight, in soft bottoms of suitable penetrability; but are difficult to "break out" if fouled in rocks or wreckage.
Like the "old style" anchor, the protruding stocks are exceedingly vulnerable. About the time of the first World War, the Eels Stockless Anchor was developed and has been used extensively for salvage and mooring purposes.
Recognizing the fundamental superiority of the stockless tumbling fluke anchor, that first appeared in England in , Frederick Baldt developed and improved it in This wrought iron anchor had the head and shank connected with a ball and socket joint, the shank being round and resolvable to act as a built-in swivel.
