  • the interchangeability of the arm has the advantage that when working on pieces of material which are not easy to handle, a larger arm can be inserted which enables the material to be introduced more easily.
  • Figures 9 and 10 show a further form of construction for enabling the arms to be swung 1aterally.
  • the arm is rotatable in a holder 23 on the machine base and is arranged so that it can be fixed and taken out, for which purpose there is used a spring detent 29 which may be of a known kind (Figure 9).

  • which causes opening and closing of the contacts [0, H and 2
  • the numeral 32 denotes the main switch for the circuit of the sewing machine ( Figure 5). When this switch 32 is closed, the electro-magnets Ill, I1, 2Ia and 2lb are energized in coordination with the sequence of working operations, by reason of the control of their contacts, so that the machine which is shown in Figures 4 and 5 operates in the following manner.
  • the needle carrier 4 When the electro-magnet I0 is energized, the needle carrier 4 is moved downwardly from its upper position. The needle passes through the material being sewn and also passes together with the thread loop through the needle hole 33 in the closure plate 34 of the base I of the sewing machine. Whenther eedle reaches. its lower dead point, the contact actuatonmembers, 3i opens the contact I and thefiowof current-in the. coil [0 is-interrupted, so that the needle carrier is then moved back into its upper posie tion by the spring l2. Shortly before the needle.
  • the contact [1 is closed for a short time by the contact actuator 3i and the electro-magnet H is energized for a short time whereby the feeder id. is actuated and consequently advances the material to be sewn.
  • the contact I0 is closed by the contact actuator and the magnet coil [0 is energized, whereby the needle carrier 4 is again moved downwardly. During this downward movement the point of the needle again penetrates through the needle hole 33.
  • the shuttle l5 When the shuttle l5 reaches its end position on the right, it shiftsthe switchover contact 23 again so that the flow of current for energizing the electro-magnet 2ib-is openedby the switchover contact 23 while the circuit for the eleotro-magnet Zia is closed by the switch-over contact 23 so as to be ready for the next operation.
  • the electro-magnet 210 is not yet energized because in the meantime contact 2l is again opened as illustrated in Fig. 4. Then, on the following movements of the needle carrier, the movements. of the feeder id and the shuttle 15 are alsorepeated in time with the actuation of the contacts, in the manner described.
  • the regulation of the speed of the needlecar rier 4 is efiected by the damping action of the piston 6 in the cylinder? and the valve 8,.
  • the damping of the piston move? ment is reduced or increased as desired and, therefore, the speed of the needle carrier is increased or reduced.

( Figures 4 and 11) is provided.

  • Below these cam plates are the electrical contacts l0, 1" and 2
  • the numeral 52 indicates an easily accessible hand wheel which is fixed on the shaft 88 for manual adjustment of the sewing needle when desired. This adjustment can be effected because the power of the motor is so small that it does not constitute any danger to the person making the adjustment.
  • the speed of the motor ll is reduced by the reducing gear 45, 66.
  • the series resistance 43 enables the speed of the motor and, therefore, the frequency of the stroke of the needle carrier to be regulated as required.
  • gear 45, 46 of the above described form of construction is replaced by an infinitely variable mechanical gear of known kind.
  • a combination of both kinds of gear can also be employed.
  • the gearing shown in Figure 7 consists of two cones 53 and 54 and a belt 55 which can be moved to and fro in the axial direction by means of a lever or fork 56 whereby the speed is regulated.
  • a mechanical or electro-magnetic damping device for regulating the speed of the needle carrier can be dispensed with and, further, the sewing speed can be regulated to a sufiicient extent by the motor ll which drives the contact-making means, which was not possible with the hitherto known and usual sewing machine driven by an electric motor.

  • Such locating of the needle carrier cannot be obtained with the known sewing machines having an electric drive.
  • the needle carrier Since the cams 49, 50 close the contact 10' in one position, and open the contact in a position turned 180, and these positions correspond to the upper, or lower position of the needle carrier, the needle carrier is stopped in the upper, or in the lower position when the cam 49, 5B which actuates the contact I0 is arrested in one of two predetermined positions which are spaced for 180.
