The feed bar, as its name indicates, had four distinct motions, two vertical and two horizontal. It was first raised by the action of an eccentric on the driving shaft, then carried forward by a cam formed on the side of the eccentric (by which operation the work was shifted the desired distance), then it dropped, and finally it was drawn back ...
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".
Page 2 from Wilson's patent 7776, showing the shuttle. It was actually invented by Allen B. Wilson in 1850, just one year before he would invent the rotary hook design that would eventually prevail over all other lockstitch bobbin driver designs. Wilson's original patent is US patent 7776, granted 12 November 1850, with reissues RE345 on 22 ...
A winder being used in the construction of a transformer, at a technical college workshop. A winding machine or winder is a machine for wrapping string, twine, cord, thread, yarn, rope, wire, ribbon, tape, etc. onto a spool, bobbin, reel, etc. [1]
Transverse shuttles carry the bobbin in a boat-shaped shuttle, and reciprocate the shuttle along a straight horizontal shaft. The design was popularized in Singer's 'New Family' machine. [2] The design became obsolete once the other bobbin driver designs were developed. [3] Shuttle from a transverse shuttle bobbin driver
The rotary hook or rotating hook is a bobbin driver design used in lockstitch sewing machines since the 19th century. It triumphed over competing designs because it can run at higher speeds with less vibration. Rotary hooks and oscillating shuttles are the two most common bobbin drivers in use today.
The bobbin winder is mounted high on the pedestal, where a small rubber tire occupying its pulley makes contact with the motor belt. The new mounting position solves the bobbin winder belt problem discussed later. Dedicated motor mounting lugs, cast into the rear of the pillar, standardize the position of the motor bracket.
A bobbin or spool is a spindle or cylinder, with or without flanges, on which yarn, thread, wire, tape or film is wound. [1] Bobbins are typically found in industrial textile machinery, [2] as well as in sewing machines, fishing reels, tape measures, film rolls, cassette tapes, within electronic and electrical equipment, and for various other ...
