The lockwork mechanism is unique and interesting. The magazine well, providing a smooth, even trigger release. It has a stirrup-shaped connector bar that runs on either side of Like most 6.35 mm pistols, the WTP is an unlocked breech design. Until the advent of the WTP II, the gun was just called the WTP. , there were almost certainly patents filed in 1917 or 1918. But if there were completed prototypes in 1917 Neither of these two early prototypes features the cocking indicator which was patented in 1922. The guns illustrated in these patents are similar in outline to the unserialled prototype shown on page 147 of Mauser Pistolen and the serial number 1 prototype shown on page 148, whichįortuitously has the date 1917 engraved on the slide. The patent describes it as effectively a loaded chamber indicator. German patent 370907, filed 9 June 1922 and granted 25 August 1923, which covers the cocking indicator mechanism of the WTP.There should be a German patent corresponding to this Austrian patent, but we have been unable to locate it. Austrian patent 93959, filed and granted 8 March 1923, which covers the disconnector mechanism, but contains a patent drawing which shows the entire mechanism of.After extensive searching we have found only two patents for the WTP. They mean in Germany-but we have been unable to locate a German patent for this year either. Klaus-Peter König and Martin Hugo, in their book Taschen Pistolen, state that the WTP was patented in 1918-we assume We would be grateful to anyone who can locate this patent. We have been unable to locate the patent for barrel retention, possibly because it is not under the Heinzelmann name (Weaver, Speed, and Schmid state it was patented by a company owned by Mauser’s need to fulfill military contracts during World War II. It appears to have been discontinued before the end of 1940 due to Most sources state that the WTP II was first made in 1938, though the 1937 Geco catalogue already has it listed. There are two distinct types of WTP, known as the WTP I and the WTP II. WTP is the abbreviation for Westentaschenpistole, or vest pocket pistol. Mauser Pistolen is the only source that references Heinzelmann in relation to the WTP. The patents for the Heim pistol were filed in 1924 and granted in 1926, but none bears any relationship to the Mauser WTP. It carries the company’s name on the slide and appears to have been made for a short time in the early 1930s.” The Heim pistol does not use the same barrel removal system as the Mauser WTP. “Heinzelmann made the Heim pistol, a 6.35mm blowback automatic that externally resembles the Mauser WTP, but internally, is closer to the Browning 1910 with a fixed barrel and a coaxial return spring secured by a muzzle bushing. Weaver, Speed, and Schmid, in their book Mauser Pistolen, state: “Instead of designing a new pistol, Mauser simply bought the rights to an existing simple blowback design, with aīarrel removal system patented in 1917 by a company owned by a C E Heinzelmann of nearby Plochingen am Neckar.” They reference Hogg and Walter’s Pistols of the World, which states: (known as vest pocket pistols) and, as the end of World War I drew near, the Mauser company decided it was time they manufactured one. The Mauser Model 1910 in 6.35 mm Browning was by any measure a remarkably successful pistol, but the 6.35 mm Browning cartridge was originally designed for the smallest of personal protection pistols

It also makes it easier for wheelchair users to easily use the sink and other fixtures. ![]() (ADA 305.3) Knee and Toe Spaceĭesigning with proper knee and toe space ensures fewer bumps and bruises as people move around the bathroom. For a parallel approach, this would be 48 inches wide by 30 inches deep. For a forward approach, this would be 30 inches wide by 48 inches deep. There needs to be clear floor space to allow for either a parallel or forward approach for each element in the bathroom. The turning space in a bathroom can also include the space underneath fixtures, as long as there’s appropriate toe and foot space provided. In smaller bathrooms, this turning space can be t-shaped with aisles of at least 36 inches wide, so a wheelchair can make a 3-point turn. Turning Spaceįor a wheelchair to make a 180 degree turn within the bathroom, there needs to be a circular clear floor space that’s at least 60 inches in diameter. Instead, the code outlines how much clear floor space is needed around each element of the bathroom.įrom turning space to clearance around toilets and showers, there are many practical considerations that need to be included in any ADA bathroom layout. To start with, the ADA requires a clear floor space of at least 60 inches in diameter for the turning space within a bathroom, in addition to the space taken up by the sink, toilet, and/or shower/tub.īut technically, the ADA does not have a minimum space requirement for the overall size of an accessible bathroom. But there are many factors that could impact this. Without a shower, the bathroom can shrink to 37.5 square feet. With a shower, the smallest ADA bathroom could be about 54 square feet. Unfortunately, the answer to this question isn’t so clear-cut.
![]() The game we know as keno has its origins set in relatively-old China. Origins of Keno and Where It Stands Today Keep in mind that the likelihood of drawn numbers is the same no matter how many times a number has been drawn. It is common for many of these numbers to exist during a handful of keno rounds, as some will simply fail to show up in a game altogether.
![]() It lends an air of lucid efficiency to any typographic message with its clean, no-nonsense shapes. Helvetica is one of the most famous and popular typefaces in the world. These features, together with the inherent, complex beauty of Mariage's forms, make this typeface a perfect choice for certificates, awards, and newsletter mastheads. Especially in the United States, classicist Old English typefaces are thought to espouse tradition and journalistic integrity. For contrast, compare Mariage to a classical German fraktur design, Fette Fraktur, a schwabacher style face, or the popular early 20th Century calligraphic gothic from Linotype, Wilhelm Klingspor Gotisch. Old English style types often appear drastically different from other blackletters. ![]() For an example of what these Victorian designs looked like, check out the popular 1990 revival of the genre, Old English. Benton's design for ATF builds upon earlier Victorian classicist interpretations of Old English/textura letters. Today, this sort of update is often referred to not as "modernization" but as classicism. They desired to modernize this old style. Yet they also found the basic medieval textura letterform too difficult to read by present standards. During the Victorian era, designers admired the Middle Ages for its chivalric, community-based values and its pre-industrial lifestyle. Mariage is heavily classicized sort of Old English type. For northern Europeans, texturas remained the most popular form of typeface design until the invention of the fraktur style in Nuremberg. Italian printers stopped using them around 1470. Continental printers had been printing with textura style letters since Gutenberg's invention of the printing press fifty years earlier. The Old English style is a subset of blackletter type that dates back to 1498, when Wynken de Worde introduced textura style printing to England. ![]() Their forms often print large amounts of ink upon the page, creating text that leaves a heavy, black impression. These letters, called gebrochene Schriften, or "broken type" in German, are normally elaborately bent and distorted. The term blackletter refers to typefaces that stem out of the historical printing traditions of northern Europe. Mariage, which has been sold under a plethora of different names during the last century, is a blackletter typeface belonging to the Old English category. Morris Fuller Benton, the principal designer of the American Type Founders, designed Mariage in 1901. |
