During the 1830s, the most popular valve drive for steam locomotives was known as gab motion in the United Kingdom and V-hook motion in the United States. [3] The gab motion incorporated two sets of eccentrics and rods for each cylinder; one eccentric was set to give forward and the other backwards motion to the engine and one or the other could accordingly engage with a pin driving the ...
Eight years later the company changed its name to Speed Products and created the first top-opening stapler, allowing easy refilling of a full strip of staples. [3] The design of this stapler, called the "Swingline" in 1935, [4] eventually became the industry standard. In 1956 the company was renamed Swingline, and in 1968 introduced the ...
A quick-return mechanism is a subclass of a slider-crank linkage, with an offset crank. Quick return is a common feature of tools in which the action is performed in only one direction of the stroke, such as shapers and powered saws , because it allows less time to be spent on returning the tool to its initial position.
This inverted slider-crank is the form of a slider-crank linkage that is often used to actuate a hinged joint in construction equipment like a crane or backhoe, as well as to open and close a swinging gate or door. [2] [3] [4] A slider-crank is a four-bar linkage that has a crank that rotates coupled to a slider that the moves along a straight ...
Slider-crank chain inversion arises when the connecting rod, or coupler, of a slider-crank linkage becomes the ground link, so the slider is connected directly to the crank. This inverted slider-crank is the form of a slider-crank linkage that is often used to actuate a hinged joint in construction equipment like a crane or backhoe, as well as ...
Perhaps the best known example is the Watt four bar linkage, invented by the Scottish engineer James Watt in 1784. [3] This type of linkage is one of several types described in Watt's 28 April 1784 patent specification. However, in his letter to Boulton he was actually describing a development of the linkage which was not included in the patent.
The original 3.3 engine, as well as the larger 3.8, are pushrod engine designs. The 3.3 was introduced in 1989 with the 1990 Chrysler Imperial, New Yorker, and related K-series models, and was joined in 1991 by the 3.8. Production on the 3.3 was stopped in 2010 after a run of 5,076,603 [2] engines, while the 3.8 remained in production until May ...
