Rawlplug
The Rawlplug Group is a company involved in the production of fixings, fasteners, and other tools. History Rawlings Brothers, a small plumbing and electrical engineering company, was founded in 1887 in London. In 1910, the company was awarded a contract by the British Museum, which required them to unobtrusively fix electrical fittings to the museum walls. The contract led to the invention and patenting of the world's first wall plug, which became a standard solution for attaching things to walls. John Joseph Rawlings, who is credited with the invention of the wall plug, named his product Rawlplug, using the first syllable of his last name, and renamed his business to Rawlplug in 1919.

Wall Plug
A wall plug (UK English),In US English, a wall plug would likely be understood as an electric socket on a wall, although that is a misnomer as a socket is a device that accepts a plug. also known as an anchor (US) or " Rawlplug" (UK), is a fibre or plastic (originally wood) insert used to enable the attachment of a screw in material that is porous or brittle or that would otherwise not support the weight of the object attached with the screw. It is a type of anchor that, for example, allows screws to be fitted into masonry walls. In US English, mentions of drywall anchors are sometimes meant (and taken) to refer specifically to the type of plastic wall plugs with expandable wings for hollow walls, in contradistinction with mollies and toggle bolts. There are many forms of wall plug, but the most common principle is to use a tapered tube of soft material, such as plastic. This is inserted loosely into a drilled hole, then a screw is tightened into the centre. As the screw enters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Joseph Rawlings
John Joseph Rawlings was a British engineer and inventor of the wall plug, also known from his name as the ''rawlplug''. He invented it in around 1910-11, registered a patent in 1911, trademarked the ''rawlplug'' name in 1912 and was granted the patent in 1913. In 1919 his company, formerly known as the Rawlings Brothers, was renamed to Rawlplug Ltd. Wall plug The original device was a jute fibre cylinder inserted into a hole drilled in the masonry and into which the screw was inserted. The deeper the screw penetrated, the more the fibre expanded and the greater the grip against the masonry. The jute was replaced by a thermoplastic plug in the 1960s, injection moulded Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for ... singly, or in multiples attached together by the original sp ...

European Organisation For Technical Approvals
European Organisation for Technical Assessment (EOTA) (german: Europäische Organisation für Technische Bewertung, french: Organisation européenne pour l'évaluation technique) is a European non-profit association. Its primary purpose is to draft the European Technical Assessment (ETA) documents. Once ratified, these become EU standards. Manufacturers and vendors of products that display the CE mark warrant that their products meet these standards . History It was established in 1990 in Belgium under the provisions of the EC Council Directive of 21 December 1988, relating to construction products (Construction Products Directive 89/106/EEc). As from 11 June 2013, EOTA reregistered as the organisation for technical assessment according to Article 31 of the Regulation (EU) No 305/2011 of the European Parliament and of the Council of 9 March 2011, laying down harmonised conditions for the marketing of construction products and repealing Council Directive 89/106/EEC (this Regulatio ...

Manufacturing Companies Established In 1887
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final product. T ...

Engineering Companies Of The United Kingdom
Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specif ...
