Motors, gearing for.-In driving-arrangements for sewing-machines &c. comprising a friction disc d mounted on the motor shaft b, a similar disc e mounted on a countershaft c aligned with the shaft b, and a pulley f from which the machine shaft is driven, the motor B and the power transmitter C are mounted on a rigid metal base-plate A, so that the whole forms a single unit adapted to be mounted on the underside of the table of the machine and the difficulty of aligning the shafts b, c is obviated. The shaft c is movable endwise to operate the clutch by means of a lever g in known manner, a stud l revoluble in the end of the shaft being interposed. A brake m is applied to the disc e when this is separated from the disc d,
