DRIVING MECHANISM FOR SPINNING AND LIKE SPINDLES.
Application filed February 5, 1924. Serial No. 690,744.-
To all whom it may concern:
Be it known that we, Goneox FnAsnR, NORMAN FRASER, and JOHN FRAsER, all British subjects, and residents of Arbroath, Scotland, have invented certain new and useful Improved Driving Mechanism for Spinning and like Spindles, of which the following is the specification.
The invention relates to spinning and like spindles; and has for its object to provide an improved construction of driving mechanism therefor so that any vibration or other irregularity transmitted to the driving wharve by its driving means will not be imparted to the spindle.
The improved driving mechanism is principally intended for use in connection with what is known as friction driving, that is where a. driving disc bears frictionally on the spindle wharve, but is also applicable where the usual hand driving is employed; and it comprises essentially a driving wharve or the like on a separate spindle, or carried separately from the spinning spindle with which however it is axially separated but coaxial. means for driving the wharve, a support for the wharve such that it may be freed from the driving means and the rotation of the spindle stopped, and a universally flexible coupling between wharve and spindle.
Figures 1 and 2 on an accompanying sheet of explanatory drawings are elevations at right angles to each other of parts sufficient to show an illustrative example of the invention as applied to a friction driven spindle.
In carrying out the invention according to this example, the spindle A is carried in upper and lower bearings of usual form (not shown) in a bolster B secured by a pinching screw C in the upper rail D of the frame. Beneath the lower protruding end of the spindle A a driving wharve E is mounted on bearings of any usual form (not shown) on an upwardly projecting part of a lever G pivoted in the lower frame H. On the lower end of the spindle A and on the upper side of the driving wharve E there are screwed or otherwise secured caps J. K the outer ends of which are conical and slotted. One end of a spiral spring L is held in the slot in the cap J and in the other end in the slot in the cap K. Instead of this spiral spring L any other known form of flexible coupling may be connected to the wharve E and to the lower end of the spinning spindle A. The wharve E is rotated as usual by a disc M bearing frietionally thereon and carried on a driven shaft N.
It has been found in practice that the frictional contact surfaces between the disc M and wharve E wear irregular through time so that the drive is not uniform, and vibratory movement is thereby imparted to the wharve. The flexible coupling L between wharve E and spindle A effectively absorbs this irregularity in the drive so that it is not transmitted to the spindle.
The lever G is controlled by a spring or weight (not shown) in known manner so as to hold the wharve E in contact with the driving disc M, and to move the wharve clear of the disc when it is desired to stop the spindle A the lever i is turned on its pivot against the action of the spring.
'iUternatively, the wharve may be driven by any other convenient or usual means such as a driving band.
\Vhat we claim is 1. In driving mechanism for spinning and like spindle, caps on the lower end of the spinning spindle and on the upper side of the driving wharve, and a spiral spring coupling extending between and secured to these cups.
2. In driving mechanism for spinning and like spindles, caps on the lower end of the spinnin spindle and on the upper side of the driving wharve, a spiral spring coupling extending between and secured to these caps and a support for the driving wharve such that it may be freed from its driving means.
In testimony whereof we have signed our names to this specification.
