Abstract: 1,190,539. Mounting electric motors. MEFINA S.A. 18 Oct., 1968 [28 Nov., 1967], No. 49521/68. Heading H2A. A mount for pivotally supporting an electric motor 1 so that the latter may be turned angularly relative to a frame 2 about an axis of rotation comprises an insulating plastics material sleeve 11 engaging a hole in a casing 6 of the motor and a screw 14 supported by a foot 4 connected to the frame, the screw engaging the sleeve and the sleeve having an insulating flange 12 interposed between the foot and the casing, the flange having a lip 13 engaging the periphery of the foot so as to insulate the casing from the frame and prevent rotation of the sleeve when the motor is swung about the axis. In the arrangement shown, two supporting feet 4 form part of a stirrup-shaped bracket 3 secured to the frame 2 and each foot carries a screw 14 in threaded engagement with an associated sleeve 11. One of the screws may be replaced by a rivet. Angular movement of the motor is effected by a cam 17, Fig. 2 (not shown), and cam follower (20), the latter being attached to the motor casing and being made of insulating material and being held against the cam by a spring attached to the motor casing through an insulating grommet.

Abstract: 1,156,420. Sewing machines. MEFINA S. A. 13 June, 1968 [6 July, 1967], No. 28079/68. Heading D1G. A sewing machine comprises a motor pivotally mounted in the machine frame, manually operable means enabling the motor to be tilted into any one of three positions, in the first position a motor drive wheel being disengaged from a handwheel and from a spoolwinding shaft, in the second position the drive wheel being drivingly engaged only with the handwheel, and in the third position the drive wheel being drivingly engaged only with the spool-winding shaft, and means for locking the handwheel in a predetermined position when the motor is in the first position. A motor 3 is pivotally mounted on a pair of fixed pins 6 within the hollow standard 2 of a sewing machine. plate 19, carried by motor 2, is formed with a cam follower finger (23) biased by a spring 28 into engagament with an axial cam 17 rigid with a knob 15 journalled in standard 2. In a second angular position of knob 15, follower (23) engages a recess 25 in cam 17, whereby motor 8 tilts to a position II in which a friction wheel 8 on the motor shaft drivingly engages a handwheel 7 on the arm shaft 41. In a third position of knob 15, follower (23) engages a lobe 26 of cam 17, whereby motor 8 tilts to a position III in which wheel 8 is disengaged from handwheel 7 and drivingly engages a wheel (12) on a vertical spool-winding shaft (9). A radial cam 18, rigid with knob 15, co-operates with a follower finger 32 on a lever 30 pivoted at 31 on the machine frame and biased by a spring 36 to engage finger 32 with cam 18. When knob 15 is turned to the second and third positions, finger 32 enters respective notches 39, 40 in cam 18. When knob 15 is turned to a first position, follower (23) engages a portion 27 of cam 17 and motor 3 assumes an upright position 1 in which wheel 8 is disengaged from wheels 7 and (12). The thread take-up lever of the machine is then in a withdrawn position, and a finger 34 on lever 30 enters a notch 35 in handwheel 7.

Abstract: 1,131,710. Sewing machines. MEFINA S.A. 13 Oct., 1967 [8 Nov., l966], No. 46782/67. Heading DIG. Flaps are hinged to the lower part of a sewing machine frame and may be either raised to engage the upper arm to form an enclosure therewith, or lowered to constitute a ramp upon which work may slide towards the work plate. As shown, front and rear flaps 10 and 12 respectively are hinged at the work-supporting surface 9 of the base 2, and in the raised position abut the upper arm 4, said flaps then lying in a recess 17 formed in the column 3 to form a smooth surface therewith. A similar end flap 14 abuts the head 5 in the raised position. The raised flaps are retained by spring catches 16. A pivoted handle 18 is provided. A trough provided in the upper part of arm 4 is closed by a hinged cover 29. The end flap may be hinged to one of the side flaps and in the raised position be secured to the other side flap. The end flap may be omitted, or an end flap slidable upon head 5 may be provided.

Abstract: A mechanism for a sewing machine for enabling the manual or automatic control of the direction and of the amplitude of movement of a transporting claw guide for material to be sewn. The mechanism is driven from the main driving shaft of the sewing machine via a cam and a series of intermediate lever members connected to a rotatable shaft connected to the transporting claw guide. The control is automatically accomplished by means of a cam driven from the main driving shaft of the machine via the arrangement of levers to obtain back-and-forth movement of the claw guide or, when a cam follower is disengaged from the cam, the control can be accomplished manually without the automatic back-and-forth movement.

Abstract: A pre-assembled sub-assembly of a plate carrying a needle bar on an oscillable cradle is mounted in a head at the free end of the upper arm of a zig-zag sewing machine. The upper edge of the plate is pivotally suspended from and slidable along a transverse bar. The plate is angularly fixed with the bore of a member on the needle bar in alignment with and receiving a gudgeon of a crank rod driven by the principal shaft of the machine, and is fixed on the bar to align the needle bar for cooperation of the needle with a shuttle hook.
