Pmmdi-eb. 2a, 1939 PATENT OFFICE PORTABLE CASING TRANSFORMABLE INTO A TAISLE FOR SEWING MACHINES Ramon Casas Robert, Barcelona, Spain Application December 9, 1936, Serial No. 114,958 In Spain February 15, 1936 7 Claims. (01. is-aaz) The invention has among its objects to provide aportable casing in which to place and to carry portable sewing machines and which is also adapted to be used as a work-table by a convenient changing of the positions of its component parts in such manner that the table is disposed at the level of the plate of the machine on which the garment or other object to be sewn is placed.

The use of a portable casing of this kind to form the casing of the sewing machine avoids the use of additional tables for increasing the surface on which the garment may be placed, so that the machine itself need only be provided with a platform of reduced area in the form of an elongated arm, so that certain articles or parts of garments of a tubular form, such as sleeves, stockings, or like articles, can

be sewn.

The invention is diagrammatically illustrated byway of example in the accompanying drawings:

Figure 1 is a perspective view of the outside of the portable casing according to the. invention.

Figure 2 is a view corresponding to Figure 1, assuming that the cover is slightly raised away from the base.

Figure 3 is an elevation of the portable casing without the sewing machine and disposed horizontally, the view being taken looking from the bottom upwards.

Figure 4 is a side elevation illustrating the method of opening the casing.

Figure 5 is a perspective view of the casing opened out ready for use as a table or platform for a sewing machine.

Figure 6 is a view corresponding to Figure 5,

.but showing the sewing machine fitted to the opened casing serving as a platform.

Figure '7 is an elevation showing the base of the sewing machine adapted for the mounting thereon of the casing serving as a cover for the machine.

Figure 8 is a sectional elevation of the base of the machine showing the locking device for the casing as well as the lower part thereof.

The portable casing according to the invention is released or locked in relation to the base of the machine by means of a bolt I. After release the casing can be raised by means'of the handle 2 from-the base 3 of the machine, which in the closed position, forms the base of the casing, s shown in Figure 2.

To the base 3 are secured the component parts 24 where they are retained by means of latches 1, I which are subject to the force of springs l0 secured on a common shaft 9 on which may 15 be set the key 6 for opening the casing. These latches l move elastically when the projections 8 are introduced into the notches or

slots

24, 24, since they are set to present surfaces at a slightly oblique angle to the path of movement 20 of the projections. By reason of this arrangement the key 6 alone is adapted to open the casing.

The cover II-I2 formed as a parallelepiped which serves to enclose the machine is divided 25 into two leaves; the leaf II is less in depth than the leaf l2, the difference being represented by the thickness of a panel [3. The two leaves II, l2 are held together at the opening of the cover by two hinges l4, H, which permit 30 of the leaves being moved through 180, as is clear from Figure 4.

The hinge I5, by which the panel I3 is hinged to the leaf l2, also permits of a relative movement through 180 so that the panel may come 35 to rest on the leaf II when the latter is in the unfolded position, and may equalize the height of the leaf II with that of the leaf I2, thus forming a work-table when the two leaves are opened out in the horizontal positions, (see Figure 5). 40

In pivoting about the hinge IS, the panel l3 uncovers one wall of the portable casing. In this wall is formed a slot I6 in which may be received the platform 22 and the lowr part of the machine I, as is shown in Figure '6. When 45 the leaves II and I2 are brought together to reform the portable casing in its rectangular form, the panel I3 is revolved about the hinge l5 to cover the slot l6 by laying against the wall in which the slot is formed, as is shown in Fig- 50 ure 4. Thus the panel I3 protects from surface wear the surface of the table formed as has been described, by the two extended leaves II and I2.

The opening in the upper or end wall of the leaf l2 in continuation of the slot I6 is closed by a shutter I! hinged at one side of the said opening to swing outwardly upon the adjacent part of the said end wall.

Feet such as It support the table assembly (Figures and 6) so that it rests at the level of the platlorm .32 through which the needle 0! the sewing machine reciprocates.

In order to swing the leaves H and I2 to the Open position, the hand must first be introduced inside the cover forming the body of the portable casing to grip a handle I] fixed to a spindle carrying bolts, so that the bolls may be operated to release the two leaves, which up till then have been held by the bolts so that they may be separated. On the separation of the leaves the shutter I9 is also released from the closed position in which'it has been retained by a metal member 25 which is adapted to extend inwardly on the inner face of the end wall of the leaf When the leaves ii and I2 are separated, it thus becomes possible to raise a shutter l9 which up till then had held the panel l3 by means of an annular member of angular form, so that the said panel can be swung on the hinge l5. In order to close the portable casing; the reverse procedure is followed. The opening of the shutter i9 allows the machine 4 to be fitted into the slot i6 when it is desired to use the opened out casing as a work-table.

At 23 is disposed a drum or similar member on which is wound the flex supplying the electric current for the working and lighting of the machine.

I claim: a

1. A casing for portable sewing machines, comprised by a base member and a hollow bell-like cover removably connected to the base member, the said cover consisting of two parts meeting along a plane normal to the base member and pivotally connected together to revolve relatively. into alignment about an axis that is transverse to and disposed at the mouth of the cover, the said parts of the cover when in alignment and resting upon the edges which when the cover is closed are in contact constituting a hollow table of an inverted tray-like form, the upper surface of which is formed by the side walls of the parts and the end walls of which are respectively formed by the two parts of the top of the cover.

2. A casing for portable sewing machines provided with a base member and an elevated work platform, comprised by the base member of the machine and a hollow bell-like cover removably connected to the said base member, the said cover consisting of two partsmeeting along a plane normal to the base member and pivotally connected together to revolve relatively about an axis that is transverse to the mouth of the cover into alignment, the said parts of the cover when in alignment forming a hollow table of an inverted traylike form, the end walls of which are respectively formed by the two parts of the top of the cover, the side wall and end wall of one of the said parts being slotted to permit the hollow table to be disposed in position in relation to the sewing machine to dispose the work platform as part of the said slotted side wall.
