Two decades later, when the patents had expired and the Sewing Machine Combination patent pool had dispersed, White Sewing Machine Company employees D'Arcy Porter and George W. Baker built a new machine that made successful use of it. The "White Sewing Machine", as it was first named, entered production in 1876. It was popular in its time, and ...
In 1868, Stephen French, working at the Gold Medal Sewing Machine Company in Orange, Massachusetts, patented an improved method of driving the vibrating arm. He used this mechanism in his designs of both the "Home Shuttle" sewing machine (from Johnson, Clark & Co., a related enterprise) and the Gold Medal "Home" sewing machine.
Robot calibration is a process used to improve the accuracy of robots, particularly industrial robots which are highly repeatable but not accurate. Robot calibration is the process of identifying certain parameters in the kinematic structure of an industrial robot, such as the relative position of robot links.
The idler arm is attached between the opposite side of the center link from the Pitman arm and the vehicle's frame to hold the center or drag link at the proper height. "Pitman arm" can also refer to a component in a treadle sewing machine that connects the foot pedal to the crankshaft of the lower flywheel. In this case, the Pitman arm works ...
For this hybrid machine he received patent US 8296, issued 1851-Aug-12 , (reissued as RE914 on 28 February 1860). Knowing that such a machine would surely lead to patent litigation with his former partners who had bought out the patent for the vibrating shuttle, Wilson kept working, and developed a refined design which kept the bobbin stationary .
Longarm quilting is the process by which a longarm sewing machine is used to sew together a quilt top, quilt batting and quilt backing into a finished quilt.. A complete longarming system typically consists of a sewing machine head, a frame, a table with a layer of plastic (under which is placed a pantograph), and several rollers on which the fabric layers and batting are attached.
The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...
Trade card, ca 1900. The White Sewing Machine was the first sewing machine from the White Sewing Machine Company. [1] It used a vibrating shuttle bobbin driver design. For that reason, and to differentiate it from the later White Family Rotary that used a rotary hook design instead, it came to be known as the "White Vibrating Shuttle" or "White VS".
