This invention comprises novel J and useful improvements in a thread box and more specifically pertains to an improved sewing cabinet for retaining, dispensing and severing threads from various spools housed within said cabinet.

The principal object of this invention is to ,provide an improved sewing cabinet for housing and rotatively supporting a plurality of spools of thread; for independently dispensing thread from any of said spools; for guiding said thread during dispensing of the same to a severing means; and' for retaining the ends of the thread from which a portion has been severed in an upright position in convenient juxtaposition to the severing means.

A further important object of the invention is to provide a sewing cabinet in conformity with the foregoing objects which shall be capable of inexpensive, yet attractive and sturdy construction from plastics or similar material; and wherein the severing and thread guiding means may be conveniently mounted and carried by the cover of the receptacle portion of the sewing cabinet.

,A still further important object of the invention is .to provide an improved sewing cabinet in accordance with the preceding objects wherein a plurality of spools of thread may be compactly but rotatively housed upon a plurality of arbors formed in the interior of the receptacle These, together with various ancillary feaitur'es and objects of the inventionwhich will 'later become apparent as the following description proceeds, are attained by the present invention, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein: v Figure 1 is a top plan view of a sewing cabinet embodying the principles of this invention;

Figure 2 is a side elevational view of the arrangement of Figure 1;

Figure 3 is a vertical transverse sectional view taken substantially upon the plane indicated by the section line 3--3 of Figure 1 and showing a spool of threadrotatably journalled upon one of the arbors within the cabinet, a portion of the thread being disposedin a thread guiding means and terminating adjacent a cutting means of the device;

Figure 5 is a horizontal sectional view taken substantially upon the plane of section line 5--5 of Figure 2;

Figure 6 is a fragmentary perspective view of a portion of the cover illustrating the thread guiding and thread severing means thereof;

Figure 7 is a perspective view similar to Figure 6 and illustrating the manner in which the device is employed for severing a portion of a thread; and,

Figure 8 is a fragmentary top plan view of the thread retaining and guiding means and is arranged with respect to the threadv severing means.

Referring now more specifically to the accompanying drawings, wherein like numerals designate similar parts throughout the various views, attention is directed more particularly to Figures 1-5, wherein it will be seen that the sewing cab- I0 having a bottom wall [2 and marginal upstanding side walls [4 which are open at their upper end, together with a cover indicated generally at l6 which may be of any suitable material such as Lucite or other transparent material, and which has a top wall l8 together with a marginal depending side wall or rim 20 which slidably embraces the upper portions of the side tubular arbors 22, which as shown in Figures 1 and 5, may be disposed in two or more parallel rows, these arbors being conveniently formed or composed of upwardly and inwardly extending hollow projections from the material of the base l2 0f the cabinet, these arbors constituting sleeve members which are closed at their upper ends, and adapted to constitute axles upon which may be rotatably positioned suitable spools 24 having a winding 26 of thread thereon, as shown in Figure 3.

Conveniently, although not necessarily, the receptacle I0 may be formed of a suitable plastic,

whereby the arbors may be extruded or molded from the material when the receptacle is formed.

Ofcourse, the arbors could be separately constructed and attached in any convenient manner to the walls or floor of the receptacle, although 3 the construction shown is deemed to be preferable from the practical standpoint.

As illustrated, 14 spools, in two rows of seven spools each may be rotatably mounted upon vertical arbors in the receptacle, although it will be readily apparent that the invention is not limited to any particular number of spools or any particular arrangement of the arbors, it being merely an advantage of this invention to provide a compact manner for journalling a large number of spools with the thread of each spool being independently accessible for use.

As shown more particularly in Figures 2, 3 and 5, the side walls [4 of the receptacle, adjacent each of the arbors, is provided with a vertical slot or opening 28 opening downwardly from the upper edge of the side wall.

The depending rim 20 of the cover is adapted to terminate, in the completely closed position of the cover upon the receptacle, slightly above the lower edge or end of each of the slots 28, as shown in Figure 3, to thereby provide an opening or aperture through which 'a thread 30 from one of the spools 24 may extend, to the exterior of the receptacle, as shown in Figure 3.

Thus, when the cover has been removed, a spool may readily be removed or inserted upon one of the arbors, and a thread 30 thereof may be then disposed through the open upper end of one of the slots 28, and to the exterior of the receptacle, whereupon the cover may be placed in place to thus lock the thread in its opening or slot. Conveniently, the upper end of the'arbor 22 may be disposed in such a relation to the top wall [8 of the cover, that a spool 24 disposed in the arbor cannot be removed from its arbor while the cover is in place. The cover thus serves to not only lock or secure the thread in its dispensing opening 'or slot, it also serves to lock or retain the spools 'u'po'n'the'arbor, while permitting a limited upward movement of the spool upon the arbor and freely permitting rotation of the spool thereon.

As will now be more apparent from Figures 3, 4 and 6, the depending rim 2!] of the cover I5, is provided at its upper edge with a laterally extending portion 32. The top wall 18 of the cover is likewise provided adjacent each of the slots 28, with a plurality of marginal recesses 34 which communicate by means of a narrow channel or slot 36 with the exterior surface of the enlargement 32, as shown particularly in Figure 6.

Embedded, or otherwise firmly secured in the material of the top wall 18, is a knife 38 of any suitable material, provided with a severing edge 40 extending across the narrow channel 36, and spaced from the outer surface of the lateral enlargement 32. The lateral enlargement 32 is'provided with a vertical wedge-shaped or V-shaped channel or groove 42 which extends entirely through and to the exterior surface of the enlargement 32, and which is disposed within the narrow channel 36 and adjacent the severing edge 40 of the knife 38. i

This wedge-shaped channel 42 constitutes a thread guiding and retaining means for the thread 30 of each of the spools, and serves not only to guide the thread into position whereby the same may be severed by the knife edge 40, but also retains in vertical position in wedging engagement in the channel 42, the remaining vportion of the thread ready for the next dispensing and severin of the thread.

Obviously, if desired, the knife members 38 may be detachably secured and retained in any desired manner in their recesses 34, so that the same can be replaced as desired. However, in

4 some instances it will be found preferable to form these knives of any suitable high quality cutting material and permanently retaining the knives as by embedding the same in the plastic material of the cover, with their cutting edges extending across and in spaced relation to the V-shaped recess 42 to provide a clearance to receive the thread 33 as previously mentioned.

During the operation of the device, it will be seen that any desired thread may be selected, and by placing the finger of the user upon the same as shown in Figure '7, the thread may be forced upwardly of its guide and retaining slot 42, from the position shown in Figure 4 to the position shown in Figure '7, at which time any desired quantity of thread has been dispensed, and the end of the thread may then be pulled against the knife edge to sever the thread as shown in Figure '7.

From the foregoing, the construction and operation of the device together with its many advantages will be readily apparent and further explanation is believed to be unnecessary.

However, since numerous modifications and changes will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not desired to limit the same to the exact construction shown and described, but all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
