Caulkin
A caulkin (or ''caulk''; US spelling "calkin" or "calk") from the Latin '' calx'' (the heel) is a blunt projection on a horseshoe or oxshoe that is often forged, welded or brazed onto the shoe."Know Foot Know Horse", knowfootknowhorse.com, 2008, webpageKnowFKH-20"Farrier Competition Results 2008", Forge and Farrier, UK, 2008, webpage/ref> The term may also refer to traction devices screwed into the bottom of a horseshoe, also commonly called shoe studs or screw-in calks. These are usually a blunt spiked cleat, usually placed at the sides of the shoe. Use Caulkins or studs improve a horse's balance and grip over uneven or slippery terrain, allowing the animal to move better and jump more confidently in poor footing. Screw in calks are most often seen in speed sports, such as eventing, polo, and show jumping, although they are sometimes used for dressage. Forged caulks of various styles are more often seen on race horses and working animals such as draft horses and some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horseshoe
A horseshoe is a fabricated product designed to protect a horse hoof from wear. Shoes are attached on the palmar surface (ground side) of the hooves, usually nailed through the insensitive hoof wall that is anatomically akin to the human toenail, although much larger and thicker. However, there are also cases where shoes are glued. Horseshoes are available in a wide variety of materials and styles, developed for different types of horse and for the work they do. The most common materials are steel and aluminium, but specialized shoes may include use of rubber, plastic, magnesium, titanium, or copper.Price, Steven D. (ed.) ''The Whole Horse Catalog: Revised and Updated'' New York:Fireside 1998 , pp. 84–87. Steel tends to be preferred in sports in which a strong, long-wearing shoe is needed, such as polo, eventing, show jumping, and western riding events. Aluminium shoes are lighter, making them common in horse racing where a lighter shoe is desired, and often faci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft Horse
A draft horse (US), draught horse (UK) or dray horse (from the Old English ''dragan'' meaning "to draw or haul"; compare Dutch ''dragen'' and German ''tragen'' meaning "to carry" and Danish ''drage'' meaning "to draw" or "to fare"), less often called a carthorse, work horse or heavy horse, is a large horse bred to be a working animal doing hard tasks such as plowing and other farm labor. There are a number of breeds, with varying characteristics, but all share common traits of strength, patience, and a docile temperament which made them indispensable to generations of pre-industrial farmers. Draft horses and draft crossbreds are versatile breeds used today for a multitude of purposes, including farming, draft horse showing, logging, recreation, and other uses. They are also commonly used for crossbreeding, especially to light riding breeds such as the Thoroughbred, for the purpose of creating sport horses of warmblood type. While most draft horses are used for driving, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Police Horse
Mounted police are police who patrol on horseback or camelback. Their day-to-day function is typically picturesque or ceremonial, but they are also employed in crowd control because of their mobile mass and height advantage and increasingly in the UK for crime prevention and high visibility policing roles. The added height and visibility that the horses give their riders allows officers to observe a wider area, and it also allows people in the wider area to see the officers, which helps deter crime and helps people find officers when they need them. When employed for crowd control, there is a risk that some people may be trampled (resulting in injuries or death). Due to this, authoritarian regimes often use mounted police to supress protests, as the public generally does not view these "accidental" deaths as resulting from a deliberate use of deadly force. In at least one case this has resulted in the police officer riding the horse (that caused the injury) to be sued. Mounted po ...

Crampons Equitation
A crampon is a traction device that is attached to footwear to improve mobility on snow and ice during ice climbing. Besides ice climbing, crampons are also used for secure travel on snow and ice, such as crossing glaciers, snowfields and icefields, ascending snow slopes, and scaling ice-covered rock. There are three main attachment systems for footwear: step-in, hybrid, and strap bindings. The first two require boots with welts, or specialized mountaineering boots with dedicated front and rear lugs, as a cam-action lever attaches the crampon to the heel. The last type (strap bindings) are more versatile and can adapt to virtually any boot or shoe, but often do not fit as precisely as the other two types. Oscar Eckenstein designed the first 10-point crampon in 1908, dramatically reducing the need for step cutting. This design was then made commercially available by the Italian Henry Grivel. Characteristics Materials Crampons are made of steel alloy, light weight alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borium
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering for use in industrial machinery, cutting tools, chisels, abrasives, armor-piercing shells and jewelry. Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530–700 GPa, and is double the density of steel—nearly midway between that of lead and gold. It is comparable with corundum (α-) in hardness and can be polished and finished only with abrasives of superior hardness such as cubic boron nitride and diamond powder, wheels and compounds. Naming Historically referred to as Wolfram, ''Wolf Rahm'', wolframite ore was then later carburized and cemented with a binder creating a composite now called "tungsten carbide". Tungsten is Swedish for "heavy stone". Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worshipful Company Of Farriers
The Worshipful Company of Farriers is one of the Livery Companies of the City of London. The Farriers, or horseshoe makers, organised in 1356. It received a Royal Charter of incorporation in 1674. Over the years, the Company has evolved from a trade association for horseshoe makers into an organisation for those devoted to equine welfare, including veterinary surgeons Veterinary surgery is surgery performed on animals by veterinarians, whereby the procedures fall into three broad categories: orthopaedics (bones, joints, muscles), soft tissue surgery (skin, body cavities, cardiovascular system, GI/urogenital .... It also supports general charities, as do other Livery Companies. The Farriers' Company ranks fifty-fifth in the order of precedence for Livery Companies. Its motto is ''Vi et Virtute'', Latin for ''By Strength and by Virtue''. Today, the Company is one of the few Livery Companies still to play a formal role in its ancient trade.

Right-angle
In geometry and trigonometry, a right angle is an angle of exactly 90 degrees or radians corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles. The term is a calque of Latin ''angulus rectus''; here ''rectus'' means "upright", referring to the vertical perpendicular to a horizontal base line. Closely related and important geometrical concepts are perpendicular lines, meaning lines that form right angles at their point of intersection, and orthogonality, which is the property of forming right angles, usually applied to vectors. The presence of a right angle in a triangle is the defining factor for right triangles, making the right angle basic to trigonometry. Etymology The meaning of ''right'' in ''right angle'' possibly refers to the Latin adjective ''rectus'' 'erect, straight, upright, perpendicular'. A Greek equivalent is ''orthos'' 'straight; perpendicular' (see orthogonality) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Heat
The practice of using colours to determine the temperature of a piece of (usually) ferrous metal comes from blacksmithing. Long before thermometers were widely available it was necessary to know what state the metal was in for heat treating it and the only way to do this was to heat it up to a colour which was known to be best for the work. Chapman According to Chapman's ''Workshop Technology'', the colours which can be observed in steel are: Stirling In 1905, Stirling Consolidated Boiler Company published a slightly different set of values: See also * Black-body radiation *Color temperature Color temperature is the color of light emitted by an idealized opaque, non-reflective body at a particular temperature measured in kelvins. The color temperature scale is used to categorize the color of light emitted by other light sources ... * Incandescence References {{Reflist Metallurgy Temperature ...

Forge
A forge is a type of hearth used for heating metals, or the workplace (smithy) where such a hearth is located. The forge is used by the smith to heat a piece of metal to a temperature at which it becomes easier to shape by forging, or to the point at which work hardening no longer occurs. The metal (known as the "workpiece") is transported to and from the forge using tongs, which are also used to hold the workpiece on the smithy's anvil while the smith works it with a hammer. Sometimes, such as when hardening steel or cooling the work so that it may be handled with bare hands, the workpiece is transported to the slack tub, which rapidly cools the workpiece in a large body of water. However, depending on the metal type, it may require an oil quench or a salt brine instead; many metals require more than plain water hardening. The slack tub also provides water to control the fire in the forge. Types Coal/coke/charcoal forge A forge typically uses bituminous coal, in ...

Farrier
A farrier is a specialist in equine hoof care, including the trimming and balancing of horses' hooves and the placing of shoes on their hooves, if necessary. A farrier combines some blacksmith's skills (fabricating, adapting, and adjusting metal shoes) with some veterinarian's skills (knowledge of the anatomy and physiology of the lower limb) to care for horses' feet. History While the practice of putting protective hoof coverings on horses dates back to the first century, evidence suggests that the practice of nailing iron shoes into a horse’s hoof is a much later invention. One of the first archaeological discoveries of an iron horseshoe was found in the tomb of Merovingian king Childeric I, who reigned from 458-481/82. The discovery was made by Adrien Quinquin in 1653, and the findings were written about by Jean-Jacques Chifflet in 1655. Chifflet wrote that the iron horseshoe was so rusted that it fell apart as he attempted to clean it. He did, however, make an ...
