The 'present `invention relatesto ai sewingfmar chine; having` a. vertical. mountingiplate shaped approximately like. the. machinel. and'V set. at:` a right` angle, withthe.; normal direction: of; the seam, the function of said platelbeinggtorsupport the.- various; mechanical'. parts a in: working order, without the helpt` of` an outer-shell: or--housng-A Referring;V more." particularly to; the drawings wherein'v I2 have.` represented` two embodiments of my invention., Fig, 1 is a: view off. themachine with its outer shellpa-rtly tornol showing; the first embodment; Fig..V 2 shows a cross-section along-.H-IL of\Fig..1; Eig, 3 isa, crossfsection on. a'slarger, scaleg, FigA is.a.view. from beneath. of ar machine accordingto fthe second:` embodiment; the base being removed;1ig= 5:isa cross-section alongV-V ofFig'rfi` The machine according to the first embodiment asshown in..Fig-s.=.lto: 3 comprisesffanbaso'supporting a generally G-shapedl-mounting plate 3 by means of screws 2. This plate 3 is located in a plane set at right angles to the path, travelled by the seam; said-*pathbeing itselfperpendicular tothe planeof the drawing. The-material is guided under the needle.: by the presserfoot 4. The contour of` plate 3 corresponds. approximately with the contour4 of. the. machine. this being true throughout' its lower arm 3a, its upper arm 3b, its head 3c, and its vertical shank 3d.

The plate 3 bears all the mechanical parts with the exception of the electric motor, encased in a lateral bulge of the outer shell (see Fig. 2).

The bearings of the shafts of the wheel 6 driven by the motor, and of wheels 'I and 8 driven in turn by a belt 9, and of wheel 8 are all part of plate 3.

The crosses II) mark the places of the other bearings of the loop taking device, of the driving levers, of the feed-dogs, and of the rod controlling the lateral displacement of the needle I I as well as of the slack thread controlling lever I2 etc. It is to be understood that all possible constructions are not shown here, the character of the invention being that the machine shall be able to run with its outer case removed, all parts being supported by the mounting plate.

This makes for great simplicity in the assembling of the machine and in the timing and checking of its elements, which can all be easily reached for cleaning or repairing purposes.

The machinery is protected by a thin case formed by two shells I3 and I4.

These two shells are also supported by the plate 3 by means of cross-members I5, IB (see Fig. 3), and a screw I1 and a nut I8.

Another-departure?fromvthe conventional sewingfmachine lies inthe factthat the fly-wheel 8 is ina'planeyparallel to the plane-of the-drawing; (plane-of the mounting plate) `instead of being perpendicular to it. Thisafords the use of an endless. belt 9 furthe drive ofthe Wheels 6 and 'I lyingjnqthe same planeinstead of gears.

The-shells., or at least onecf` them, have an apertureenablingthefoperator to hold the rim of the. fly-wheel 8, for, the purpose of` starting or stopping. the machine. v

The bulge 5, protecting the motor could be part of the shell I4, and the shells I3 and I4 could be divided in several parts, for instance at the location of the head, in order to give access to the parts holding the needle or the slack thread controlling lever, or at the extremity of the lower arm in order to give access to the loop taking device and the bobbin case.

In the second embodiment the mounting plate 2i) is not fixed to the base but instead it is supported by the two outer shells 24 and 25 as can be seen on Figs. 4 and 5. In this embodiment the plate 20 and the motor 2| are rigidly connected by cross-members 22 forming an assembly that will remain upright without the help of the plate or the base.

As in the first embodiment, the plate 20 is connected to the shells 24 and 25 by means of crossmembers, here designated 23. But, contrary to the first embodiment, the connection to the base is not provided by the plate, but by the shells, which are provided with embossments 26, 21 and 28, and screws 29 (see Fig. 5).

The drawings show only some of the parts of the machinery, such as the pulley 30 which takes the place of the wheel 6 of Fig. 1, but it is to be aetdsot understood that the plate 20 supports all operative parts of the machinery in working order, including the motor.

To take the machine apart, it will be sufficient to'unscrew the base and to remove the shells. A block of machinery will remain, made up of the mounting plate 2i), the operating mechanism supported thereby, andthe motor, the whole being in working order so as to afford an easy inspection of the operation of all parts and to permit convenient cleaning, repairs, and replacement of parts if necessary.

W hat I claim is:

l. In a sewingmachine, the combination of a base; a supporting standard oi substantially C- shaped, plate formation rising from said base; a sewing needle and presser foot assembly operatively mounted across the open mouth of said supporting standard; drive mechanism mounted on said supporting standard, and comprising a series of drive wheels operativeiy interconnected by aV drive beit, the wheels of said series being mounted for rotation on respective axes which are perpendicular to the plane or said supporting standard; and a substantially Similarly' C-shaped housingrenclosing said supporting standard and the said drive mechanism mounted thereon.

2. 1n a sewing-machine, the combination of a base; a supporting standard of substantially C-shaped, plate formation secured to'and rising from said base; a sewing needle and presser' foot assembly operatively mounted across the open mouth or" said supporting standard; drive mechanism mounted on said supporting standard, and comprising a series of drive wheels operatively interconnected by a drive belt, the wheels of said series being mounted for rotation on respective axes which are perpendicular to the plane of said supporting standard, one of the wheels of said series being a riy wheel mounted so as to project rearwardly oi said supporting standard; and a substantially similarly CV-shaped housing enclosing said supporting standard and the said drive mechanism mounted thereon, said housing having an aperture in its rear wall, through Vwhich, a segment of the rim yof said fly Wheel projects to be available for manual manipulation.

3. The combination recited in claim 1, wherein the sewing needle and presser foot assembly are mounted in a plane transverse to the plane of the supporting standard, so as to sew a seam substahtially perpendioularly to the plane of said supporting standard.

Ki. The combination recited in claim 2, wherein the sewing needle and presser foot assembly are` mounted in a plane transverse to the plane of the supporting standard, so as to sew a seam substantially perpendicularly to the plane of said supporting standard.

5. The combination recited in claim 1, wherein the supporting standard is a flat plate of uniform'thickness; the housing is made up of substantially similarly shaped and recessed shells which meet in mutual opposition along a longitudinal plane disposed substantially centrally of the housing, said plate being disposed in a plane substantially parallel to but orset laterally from the said longitudinal meeting plane of the shells; and mutually spaced, removable and replaceable fastening devices securing saidl shells together and to said plate.

6. The combination recited in claim 5, wherein an electric motor is secured to a lower part of said plate and rests upon the said base at the side of said housing within which said plate is offset, said motor being enclosed by a shell which joins the Ysaid housing; and means securing the housingV and said motor shell to the said base.

7. The combination recited in claim 1, wherein the supporting standard is secured to the base, andthe housing is removably and replaceably secured to said standard.
