1 Claim. (Cl. 242-139) This invention relates to improvements in racks for removably supporting a plurality of thread spools and bobbins upon a sewing machine in an out-of-the-Way position, such as will not interfere with the operation of the machine for sewing, and in such relation that the spools and bobbins will be distinctively displayed for easy selection of desired thread colors. The rack can be applied quickly and without difliculty to any head type of sewing machine in such stabilized relation that it will hold the, spools and bobbins and the rack against vibrations during machine operation.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification and wherein similar reference characters designate corresponding parts throughout the several v1ews:

Figure l is a side elevation of a conventional arm type sewing machine supporting the improved thread spool and bobbin rack thereon.

Figure 2 is a perspective view of the rack, showing the various details thereof.

Figure 3 is a longitudinal cross sectional view taken through the rack substantially on the line 3-3 of Figure 2.

Figure 4 is a transverse cross sectional view taken substantially on the line 4-4 of Figure 2.

In the drawing, wherein is shown only a preferred embodiment of the invention, the letter A may generally designate a conventional type of sewing machine adaptable for supporting the improved rack B thereon. The

latter is provided with means for the demountable support of a large number and variety of thread spools such as C and C and bobbins D.

The machine A may generally consist of a conventional base or standard 10 having a horizontal arm 11 supported therefrom. The end 12 supports conventional stitching mechanism 13. This type of machine, above the standard 10, is provided with the usual vertically disposed spool supporting pin 14.

The improved rack B is adaptable for mounting upon the machine A without alteration of the latter. The material of which it is formed is preferably light in weight, such as aluminium, or a magnesium composition or plastic. It includes a supporting base 30 having several series of upstanding spool supporting pins 31 thereon and another series of bobbin supporting pins or spindles 32.

The base 30 preferably includes a platform body 35 of rectangular formation. If the base is formed of sheet metal or other suitable material it is flanged in right angled relation at 36 and 37 along the longitudinal side edges thereof. They are inturned at 38 in flanged parallelism with the platform 35, and then flange upturned at 39 and inturned at 40 in parallelism between the body 35 of the base and the respective flanges 38. These flanges are provided along the longitudinal side margins of the platform for the purposes of supporting series of p 2,940,685 Patented June 14, 1960 the spool and bobbin supporting spindles. The spindles are stabilized against eccentric tilting by providing openings 45 in the flanges 40 which align with upper openings 46 through the body 35. The lower ends of these spindles fit into the openings 45 and 46, as shown in Figure 4 of the drawing.

By way of example, I have shown that along the longitudinal side margins of the platform there are provided five spool receiving spindles 31, in each of two series. They may vary in height, depending upon the size of the spool to be used, and each of the same is sufliciently long to accommodate a considerable number of smaller spools such as the spool C shown in Figure 4.

Along the longitudinal center line of the body 35, at the rightend, there may be provided one or more openings 51 adapted to receive selectively therein the conventional stationary spool pin 14 of the sewing machine. The flanges 38 at the sides of the platform may rest upon the top of the sewing machine arm 11 or if the base 30 is sufficiently wide they may straddle the arc or contour of the head, with the base 35 between the flanges 38 engaging the base, although generally the platform will assume the position upon the sewing machine head shown in. Figure 1-. For levelling purposes, at the left end of the base body 35, an arm 50 may be struck from the material of which the rack is formed, extending-downwardly at an acute angle with respect to and below the platform 35. It may have an inturned foot 51. at its lower end, defining an arcuate surface 52 which may rest upon and engage the top surface of the head arm 11 of the sewing machine in order to level the platform body 35, as shown in the drawings. This extension 50 is bendable with respect to the plane of the base 35, at the location 53, in order that the angle of it may be changed to suit the slope of the sewing machine arm 11, which may vary in different machine makes.

An important feature of the combination rack is the fact that provision is made not only for supporting spools of thread, but also bobbins, in a relationship which will not interfere with easy observation of the color of the thread upon either the spools or the bobbins. To that end I provide a series of bobbin supporting spindles 32 which are removably supported upon the front marginal flanged part of the platform or base 30; the same having their spindle portions 60 at an angle of about 45 with respect to the plane of the platform 35. To that end these spindles 32 are provided with right angled bottom extensions 61 which support vertical feet 62. adapted to be engaged in openings in the platform base 35 and flange 40 similar to the openings 45 and 46 above described. This shaping of the bobbin spindles 32 provide for nontilting stability of the bobbin spindles. They are of a length which may accommodate a number of the bobbins D, as shown in dot and dash lines in Figure 4 of the drawing.

It is necessary in tailoring establishments,.where garments of different colors are manufactured or repaired, and particularly in valet establishments, to be continuously changing the color of threads, to suit the color characteristics of the different garments repaired or handled. Therefore, it is of great importance for the operator of the machine to be able instantly to determine the desired color of thread. This can very readily be done, due to the fact that two series of spindles are provided for the spools, and the bobbins are located on spindles between the spool spindles and forwardly of the location of the spools. The operator can easily discern the color of the thread upon the bobbins and spools and with ease remove the desired spool or bobbin.

The base ends of the

spindles

31 and 32 may be frictionally mounted in the openings 45 and 46 of the base construction for replacement or they have a stationary orfixed fit upon the base.

Variouschanges may be made to the shape, size and arrangement of parts of this invention without departing from the spirit of the invention or scope of the claim. a m 7 A spool and bobbin supporting rack for mounting upon the upper face of a horizontally disposed arm at the upper portion of a sewing machine, provided with an upwardlyextending spool supporting pin, said rack including a base of sheet material provided with a central platform body provided with longitudinal and transverseedge portions, a spool supporting pin-receiving opening intermediate said edges, and a plurality of spaced-apart openings through said central platform body at said longitudinal edge portions; means carried by said central platform body to removably support a plurality of spool and bobbin supporting spindle extending through said spaced apart openings, comprising a pair of flanges at said longitudinal edge portions, each comprising a first flange portion extending substantially normal with respect to said central platform body, a second flange portion extending from said first flange portion in substantial parallelism and facing said central platform body, a third flange portion extending from said'second flange portion in substantial parallelism with and facing said first flange portion and an inturned flange portion extending from said third flange portion between said second flange portion and central platform body toward said first flange portion, said inturned flange portion being provided with a plurality of spaced apart openings aligned axially with said spaced apart openings through said central platform body; a spool supporting spindle extending through each alternate of said spaced apart openings in said central platform body and inturned flange, with an end portion of each of said spool supporting spindles disposed upon said second flange portion; a bobbin supporting spindle extending through each of the other of said spaced apart openings in said central platform body and inturned flange portion, each bobbin supporting spindle comprising a spindle portion, an extension therefrom forming substantially a right angle therewith, and a foot extending from said extension and forming substantially an acute angle therewith, with said foot portion extending through axially aligned spaced-apart openings in said central platform body and inturned flange with thefree end portion of said foot disposed upon said second flange and said spindle portion extending upwardly and outwardly of the planes of said central platform body with the portion of said extension adjacent its connection with said foot disposed upon said longitudinal edge portion of said central platform body, whereby rocking of said bobbin supporting spindles is substantially prevented; and resilient adjustable means for levelling said central platform body upon said arm when said pin is within said pin-receiving opening.
