A door knocker is an item of door furniture that allows people outside a house or other dwelling or building to alert those inside to their presence. A door knocker has a part fixed to the door, and a part (usually metal) which is attached to the door by a hinge, and may be lifted and used to strike a plate fitted to the door, or the door itself, making a noise. The struck plate, if present, would be supplied and fitted with the knocker. Door knockers are often ornate, but may be no more than a simple fitting with a metal bob, or ring.
German professor Franz Sales Meyer distinguished three kinds of door knocker: the "ring", the "hammer", and an ornate category which could take the shape of an animal or another figure. [1] High demand for antique door knockers in the early 20th century in the United States caused forged versions to emerge. [2]
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals and sometimes non-metals, such as phosphorus, or metalloids, such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as strength, ductility, or machinability.
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a doorway or portal. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing.
In woodworking and construction, a nail is a small object made of metal which is used as a fastener, as a peg to hang something, or sometimes as a decoration. Generally, nails have a sharp point on one end and a flattened head on the other, but headless nails are available. Nails are made in a great variety of forms for specialized purposes. The most common is a wire nail. Other types of nails include pins, tacks, brads, spikes, and cleats.
A chandelier is an ornamental lighting device, typically with spreading branched supports for multiple lights, designed to be hung from the ceiling. Chandeliers are often ornate, and they were originally designed to hold candles, but now incandescent light bulbs are commonly used, as well as fluorescent lamps and LEDs.
Door furniture or door hardware refers to any of the items that are attached to a door or a drawer to enhance its functionality or appearance.
A table is an item of furniture with a raised flat top and is supported most commonly by 1 to 4 legs. It is used as a surface for working at, eating from or on which to place things. Some common types of tables are the dining room tables, which are used for seated persons to eat meals; the coffee table, which is a low table used in living rooms to display items or serve refreshments; and the bedside table, which is commonly used to place an alarm clock and a lamp. There are also a range of specialized types of tables, such as drafting tables, used for doing architectural drawings, and sewing tables.
A door handle or doorknob is a handle used to open or close a door. Door handles can be found on all types of doors including exterior doors of residential and commercial buildings, internal doors, cupboard doors and vehicle doors. There are many designs of door handle, depending on the appropriate use. A large number of handles, particularly for commercial and residential doors, incorporate latching or locking mechanisms or are manufactured to fit to standardised door locking or latching mechanisms.
A latch or catch is a type of mechanical fastener that joins two objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Depending upon the type and design of the latch, this engaged bit of hardware may be known as a keeper or strike.
A smokebox is one of the major basic parts of a steam locomotive exhaust system. Smoke and hot gases pass from the firebox through tubes where they pass heat to the surrounding water in the boiler. The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney. Early locomotives had no smokebox and relied on a long chimney to provide natural draught for the fire but smokeboxes were soon included in the design for two specific reasons. Firstly and most importantly, the blast of exhaust steam from the cylinders, when directed upwards through an airtight smokebox with an appropriate design of exhaust nozzle, effectively draws hot gases through the boiler tubes and flues and, consequently, fresh combustion air into the firebox. Secondly, the smokebox provides a convenient collection point for ash and cinders ("char") drawn through the boiler tubes, which can be easily cleaned out at the end of a working day. Without a smokebox, all char must pass up the chimney or it will collect in the tubes and flues themselves, gradually blocking them.
The Peugeot 207 is a supermini car (B) that was designed and produced by the French automaker Peugeot from 2006 to 2014. It was presented at the Geneva Motor Show in 2006, and entered production in April 2006, as the successor to the Peugeot 206. It shares the same platform with the Citroën C3.

Belt buckles and other fixtures are used on a variety of belts, including cingula, baltea, baldrics and later waist-belts.

Margent is a vertical arrangement of flowers, leaves or hanging vines used as a decorative ornament in architecture and furniture design in the 16th, 17th and 18th centuries. This motif was developed as a complement to other decorative ornaments, hanging as "drops" at the ends of a festoon or swag. Also used to accentuate the vertical lines of window frames and centered in ornamental panels.
The Artuklu Palace or Artukid Palace or Artuqid Palace was the seat of the Diyarbakır branch of the Artuqid dynasty, a Turkish Beylik that ruled eastern Anatolia and Al-Jazira in the 12th and 13th centuries.

The Celtic brooch, more properly called the penannular brooch, and its closely related type, the pseudo-penannular brooch, are types of brooch clothes fasteners, often rather large; penannular means formed as an incomplete ring. They are especially associated with the beginning of the Early Medieval period in Ireland and Britain, although they are found in other times and places—for example, forming part of traditional female dress in areas in modern North Africa.
