Definitions

  • SHEET 3 OF 3 SEWING MACHINE The invention relates to a sewing machine enclosed in a casing which has a lower free arm.
  • Sewing machines of this kind have the disadvantage that the work surface is annoyingly and inconveniently narrow.
  • the purpose of the invention is to provide a sewing machine which combines the advantages of a machine with a free arm with those of a machine having a wide work surface.
  • An object of the invention is a sewing machine that is slidable in a base which serves as part of the work surface when the lower free arm of the machine is located entirely within the base.
  • FIG. 1 shows a sewing machine of the invention closed up
  • FIG. 2 shows the machine ready for use, with a wide work surface
  • FIG. 3 is a view in three-quarter-face of the sewing machine completely opened up;
  • FIG. 4 is a side view of the machine in the position shown in FIG. 3, with the base partly in section;
  • FIG. 5 is a perspective view of a second form of the invention.
  • the sewing machine is housed in a casing 1 comprising a lower free arm 2 (best seen in FIGS. 3 and 4), a pedestal 3, anupper arm 4, and a head 5.
  • the casing rests on an elongated base 6 inform of a channel or gutter.
  • the base incorporates a bottom 7 and two longitudinal sides 8.
  • the rear part of the base 6 embodies an opening equal in size tothe width of the lower part of the pedestal 3.
  • the front part 9 of the base is hollow to form a compartment, the two surfaces I0 of the compartment forming, together with the upper face 11 of the free arm, the work surface of the sewing machine.
  • the hollow of the front part 9 of the base 6 accepts the lower part 12 of the casing 1 when the sewing machine is located in the position shown in FIGS. 3 and 4, wherein the free arm 2 projects beyond the one end of the base 6.
  • the bottom 7 of the base 6 embodies longitudinal slots 13. Projections 14 with heads pass through the slots and are rigid with the bottom of the casing 1.
  • the casing bottom is, therefore, free to slide in the base 6, so that the sewing machine can be used in the position shown in FIG. 2, with a wide work surface formed by the upper face 11 of the free arm and the complementary surfaces of the base 6. In this position, the free arm is located within the base 6.
  • the sewing machine in the position shown in FIGS. 3 and 4, can be used to sew tubular pieces, such as sleeves or trousers, by
  • the sewing machine of the invention which can be converted from a sewing machine having a broad work surface to one having a free arm, is further provided with swinging sides 15 and I6 pivotally connected to the longitudinal edges 17 of the base 6. These sides can be swung between two different positions:
  • FIG. I Another, in which the sides are closed, or swung up, as shown in FIG. I, the sides covering the upper part of the easing 1 after sewing is finished.
  • Any suitable closure means can be used to hold the sides shut.
  • the sides are snapped shut by spring catches 18 that engage in notches l9 embodied in the sides 15 and 16.
  • the sewing machine also has an end flap pivotally connected to the lower front edge 21, of the base 6, underneath the free arm 2.
  • the flap covers the front end of the free arm, as well as, when the machine is to be covered up, the head 5.
  • a spring catch I8 cooperates with a notch 19 in the flap 20, for holding the latter shut in its raised position.
  • the flap 20 comprises 'two parts 22 and 23, pivotally connected together at 26.
  • the shape of the lower part 22 is similar to that of the base front end, except for the groove of the latter.
  • the upper part 23 extends from the level of the work surface 10 and 11 to the top of the sewing machine head 5.
  • a spring catch 18 and a notch 19' as shown in FIGS. 1, 3 and 4 releaseably and securely hold the lower part 22 against the front end of the base 6, when the free arm 2 is located within the base 6. In this position, the upper part 23 is lowered to permit sewing, and forms a ramp leading to the work surface.
  • the sewing machine advantageously incorporates means for locking the casing 1 and base 6 in their two mutual positions, respectively illustrated in FIGS. 2 and 3.
  • the locks can be a conventional spring arrangement or mechanically operated by a lever or button.
  • the machine further has an accessory compartment in the upper arm 4 of the casing l.
  • the upper plate 25 of the arm 4 constitutes the cover for the compartment, and is removable.
  • a handle 26, pivotally connected in the upper part of the arm 4, enables the sewing machine to be easily carried about particularly when it is shut up.
  • FIG. 5 the lower part of which shows the sewing machine with its casing 1 slidably supported in the base 6.
  • the upper part of FIG. 5 shows the cover 27, which is placed over the casing 1 to protect the sewing machine when it is not in use.
  • the cover 27 can be sufficiently high to cover the entire machine, either from the bottom of the casing I up or from the level of the work surface 10 and 11 up.
  • the handle 26 is nonrotatably fixed to the cover 27, and any suitable releasable fastening means is used to secure the cover to the sewing machine.
  • the sides 15 and 16 can be shortened in length to cover only the open space comprised between the pedestal 3 and the head 5.
  • the arrangement to facilitate sliding between the casing 1 and the base 6 can be of any kind suitable to the purpose, such as, among others, a dovetail slide, a roller or ball bearing slide, or a slide employing guide rods.
  • a sewing machine having a casing, said casing including an upper arm terminating in a head, a lower free arm, and a work surface incorporated by said free arm, the improvement comprising a base for the sewing machine for receiving said free arm thereof and supporting the latter for relative sliding therebetween, whereby the sewing machine can be moved from a first position in which said free arm is located within said base to a second position in which said free arm projects from said base, at least one horizontal surface incorporated by said base extending from said free arm work surface to provide a work surface of increased width when the sewing machine is in said first position, said base having two sides located opposite respective sidesof said casing, two swinging side members, means for pivotally mounting said two swinging side members one on each of said sides of said base to permit each said side member to swing about a horizontal axis between an open position in which it constitutes a ramp extending to said work surface of increased width and a closed position in which it covers a respective side of the upper arm of said sewing machine casing, and releasable means for
