Abstract

21,246. Fairweather, W., [Singer Manufacturing Co.]. Oct. 20. Sewing-machines; starting and stopping gear -Relates to friction gearing, particularly applicable for driving one or more sewing- machines. The driving-shaft 1 is carried in a self-alining bearing 4 formed with a flange 5, the spherical exterior of which bears within a hanger 8 secured to a spindle 9. A ball-ended stud 18 engages a recess in the flange 5 and prevents endlong movement and rotation of the bearing 4. A triangular collar 11 secured to the spindle 9 carries a stud 12 and screws 13 so that the spindle may be adjusted in position in the bench rail 14 and secured by a nut 15. A leather-covered friction wheel 2 carried by the shaft 1 is arranged within a driven drum 24 secured to a sleeve 20 which also carries a pulley 23. The sleeve 20 is carried in a divided hanger 26 loose on the spindle 9. A lever 30 operated from the treadle carries a brake block 32 which is kept normally in contact with the driven drum 24 by a spring 33. A stud 35 on the lever engages a cam-slot 36 in the hanger 26, so that, as the brake is removed, the hanger is rotated and the drum is brought into engagement with the wheel 2. Stops are provided on the hanger 26, collar 11, and lever 30 to prevent accidental movement of the hanger. If breakage occurs, the hanger swings by gravity to the disengaging position. Gearing may replace the pulley 23. The shaft 1 may serve for driving several similar arrangements of friction gearing.
