Spline Roller
A screen roller or spline roller is a small hand tool used to press screen mesh into the edges of a window frame that is fluted on the inner edges, or to press in the retainer spline that holds that mesh in place. Often these are combined into a single tool or combined with a spline cutter; versions are currently manufactured from plastic or wood and metal. Appearance and history While a spline roller (also referred to as a "spline tool") is said to look like a less-sharp version of a pizza cutter (which it does), its origins are in fact from something different. Somewhere around or before 1920 a man named Julius Alexander Muhlberg who was co-owner of Winchester and Muhlberg, a New Jersey-based company. An innovator at heart, Julius had taken some other tool's handle, drilled a hole through a silver dollar, and after putting them both together with a nut Nut often refers to: * Nut (fruit), fruit composed of a hard shell and a seed, or a collective noun for dry and edible f ...

Hand Tool
A hand tool is any tool that is powered by hand rather than a motor. Categories of hand tools include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, hacksaws, drills, and knives. Outdoor tools such as garden forks, pruning shears, and rakes are additional forms of hand tools. Portable power tools are not hand tools. History Hand tools have been used by humans since the Stone Age when stones were used for hammering and cutting. During the Bronze Age tools were made by casting the copper and tin alloys. Bronze tools were sharper and harder than those made of stone. During the Iron Age iron replaced bronze, and tools became even stronger and more durable. The Romans developed tools during this period which are similar to those being produced today. In the period since the industrial revolution, the manufacture of tools has transitioned from being craftsman made to being factory produced. A large coll ...

Window
A window is an opening in a wall, door, roof, or vehicle that allows the exchange of light and may also allow the passage of sound and sometimes air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows may have a latch or similar mechanism to lock the window shut or to hold it open by various amounts. In addition to this, many modern day windows may have a window screen or mesh, often made of aluminum or fibreglass, to keep bugs out when the window is opened. Types include the eyebrow window, fixed windows, hexagonal windows, single-hung, and double-hung sash windows, horizontal sliding sash windows, casement windows, awning windows, hopper windows, tilt, and slide windows (often door-sized), tilt and turn windows, transom wi ...

Pizza Cutter
A pizza cutter (also known as a roller blade) is a utensil that is used to cut pizzas. History The first pizza cutter in its modern form was invented by David S. Morgan which he patented on September 20, 1892. However, it was not directly meant for cutting pizza but for cutting wallpapers. "World's Largest" Pizza Cutter is located in Casey, IL in front of The Greathouse of Pizza. Varieties There are two main types of pizza cutters. The most common uses a wheel that rotates in a circle while a person moves the cutter in a direction that they would like to cut the pizza. Many people might use the wheel pizza cutter for other things, including craft work. The other type is a large curved knife called a mezzaluna A ''mezzaluna'' (; ) is a knife consisting of one or more curved blades with a handle on each end, which is rocked back and forth chopping the ingredients below with each movement. They most commonly have a single blade, but are sometimes seen ... (Italian for "hal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Jersey
New Jersey is a state in the Mid-Atlantic and Northeastern regions of the United States. It is bordered on the north and east by the state of New York; on the east, southeast, and south by the Atlantic Ocean; on the west by the Delaware River and Pennsylvania; and on the southwest by Delaware Bay and the state of Delaware. At , New Jersey is the fifth-smallest state in land area; but with close to 9.3 million residents, it ranks 11th in population and first in population density. The state capital is Trenton, and the most populous city is Newark. With the exception of Warren County, all of the state's 21 counties lie within the combined statistical areas of New York City or Philadelphia. New Jersey was first inhabited by Native Americans for at least 2,800 years, with the Lenape being the dominant group when Europeans arrived in the early 17th century. Dutch and Swedish colonists founded the first European settlements in the state. The British later seized contro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dollar Coin (United States)
The dollar coin is a United States coin with a face value of one United States dollar. Dollar coins have been minted in the United States in gold, silver, and base metal versions. Dollar coins were first minted in the United States in 1794. While true gold dollars are no longer minted, the Sacagawea, Presidential, and American Innovation dollars are sometimes referred to as golden dollars because of their color. As with several other denominations of U.S. coinage, golden dollars are similar in diameter and color to their Canadian counterpart (known as the "loonie," which predates the Sacagawea dollar by thirteen years). However, unlike the 11-sided Canadian dollar coins, U.S. "golden dollar" coins are round. Dollar coins have never been popular in circulation since inception. Despite efforts by the government to promote their use to save the cost of printing one-dollar bills, such as the Presidential $1 Coin Program, most Americans currently use the bill. For this reason, sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nut (hardware)
A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, eccentric double nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins ( split pins) or lockwire in conjunction with castellated nuts, nylon inserts (nyloc nut), or slightly oval-shaped threads. Square nuts, as well as bolt heads, were the first shape made and used to be the most common largely because they were much easier to manufacture, especially by hand. While rare today due to the reasons stated below for the preference of hexagonal nuts, they are occasionally used in some ...
