THREAD RACK Filed Dec. 30, 1944 Patented Dec. 2, 1947 THREAD RACK Frank J. Campbell, Los Angeles, Calif., assignor to Industrial Sewfng Machine Service, Los Angeles, Calif., a copartnership Application December 30, 1944, Serial No. 570,658

4 Claims. 1 This discovery is in the art of industrial sewing and the concept is an improved thread rack.

- An object of this invention is to provide a simple, substantial, practical, low cost rack for the.

support of thread spools and the distribution of one or more threads from the spools to one or more contiguous sewing machines.

Another object of the invention is to provide, in unit form, a rack having a foot system directly fittable to postsockets of extensively used sewing machines so that no changes, alterations or attachments are necessitated.

A noticeable object of the invention is the provision of a thread rack to be mounted in a position above related machines and whose parts, for the most thereof, are made of transparent material to eliminate rack shadows resultant from roundabout light sources, as laterally from or above the installed rack.

An additional object of the invention is the provision of a rack including means to protect the spools and the running threads from the spools; to prevent the lint working from the running threads from scattering in the air at the operatives posts, and to prevent winds and drafts from whipping the threads rising from the spools to superjacent distributor means forming a part of the rack,

The invention consists of certain advancements in the art as set forth in the ensuing disclosure, and has with the above, additional objects and advantages as will be made apparent, and whose constructions, combinations, and details will be made manifest in the following description of the herewith illustrative embodiment and manner of operation; it being understood that modifications variations and adaptations may be resorted to within the scope, spirit and principle of the invention as it is more directly claimed presently.

Figure 1 is a perspective of the rack as installed on tables of sewing machines (arranged back to back).

Figure 2 is a cross-section of the spool supporting base of the rack; to show subjacent lamp attachment.

In sewing rooms of factories are grouped, in long rows, machines with opposite top tables, A and B, set in spaced, back to back relation, so that worked goods may fall clear in the space between the backs of thus arranged machines; two machine tables being shown in Fig. 1, in part.

A very extensively used type of machine top has affixed post sockets 2 and 3 near the rear corners and a feature of this invention is that a set of four legs or posts 4 is provided to be readily set into the said sockets of two of such tops A and B in their spaced relation here shown. The tops of end pairs of the legs are rigidly fastened in the end portions of related bridge or back bars 5, thus making end horses by which a longitudinal base 6 issupported.

This base is preferably formed of relatively thin, light weight material and has end portions I laid on'the backs 5 of the horses and rigidly secured in any desired manner. For rigidity, the base '6 is provided with downturned marginal flanges 8. A preferred form of means to receive and support upright thread spools (not shown) consists of a straight row of vertical, rigidly fixed spindles 9 mounted on the top face of the base 6.

Vertically above the row of spindles 9 is a thread receiving and distributing means which is here disclosed as a substantial beam [0. This preferably is in the form of a flat, stiff, elongate bar having its end portions twisted in an angle of about to the plane ,of the bar to form ears H which receive and are firmly secured on the upper ends of stanchions l2 fixed at their lower ends to the backs 5 of the horses, and about in line with the row of spindles 9, The beam [0 is provided along its length and at positions vertically over the spindles with a row of thread receiving eyes l3 from side to side and having mouths l4 opening to the top edge of the beam to facilitate laying of a thread from the vertically below and relative spindle-supported spool. It will be seen that the threads pass in a short and direct flight from spool to beam eye, and from the eyes the threads are drawn off to and by the two machines immediately at the opposite sides of the installed rack structure.

It is well known that highly objectionable lint frays ed the fast travelling threads going to relative machines. This lint is not only spread around the factory room by winds and drafts, but also the drafts cause an undesired whipping of the flights of threads from the spools. Therefore, an object of the invention is to provide means such as will stop the drift of the free lint and prevent Whipping of the threads by substan tially closing in the spools and the lengths of threads up to the distributor, and which means will give at all times a clear view of the spools and threads therefrom and will allow free flow of desired light from sources around and above the rack.

The protecting means in the preferred form consists of firm, transparent window panes l5 and IB arranged along the sides of the rack and preferably hinged at their bottom edges by hinges I! to the base so as to be easily opened away from the distributor beam ID to provide for quick change of the spools and laying in of threads on the beam eyes. Small spacers 18 set the top edge of the windows out from the beam to permit free run of the interposed threads.

Practically all of the constructional elements making up this rack are preferably made ofya substantial, transparent material, such as of thenow well known plastic groups.

A feature of the rack is thatby its central position between two manually controlled sewingmachines whose tops are here shown the base part 6 of the rack is disposed in: an elevated-pmsition as to the table tops and is heresprovidem f with hangers or fasteners [9 for preferred types:

of light sources; especially the approved clonigate forms of highly desirable fluorescent lamps 20, Fig. 2.

What is claimed is:

1. In a thread rack; the combination ofan. elongate base having cross-bars at its ends and posts'fixed'atwtheir tops-:to the ends of said! bars and forming rigid: horses: and whose feet are adaptedfon attachment tosupports such as sewing machine tables, stanchions fixedrtothebars at theends of the base; athread distributing head: fixed-at its ends to-thetops of the stanchions, and a row of vertical, coplanar spool spindlesvfixed on the baseand coplanar. with the said head to hold applied spoolsof: thread; the horses forming stabilizers-for the sta-nchions.

2; In' a thread rack; the combination of an elevated, elongate, horizontal base having a row of rigid-coplanar-upright, afiixed spool spindles, stanchions on the base, and a distributing head disposed vertically,- above the spindles and fixedon the stanchions and being pierced from side to side by horizontal axis thread guiding eyes vertically coordinate to respective spindles on the base; the eyes opening unobstructed to the top edge of the head.

3. In a thread rack; the combination of a base bar having a coplanar row of rigidly mounted spool spindles, and an elongate beam rigidly mounted on the base in the plane of and above the spindles and having thread eyes opening to the top edge of the beam and Vertically coordinate to respective spindles.

4'. The rack of claim 1; and transparent, rigid sheetswextendingisubstantially from stanchion to stanchion along: the sides of the base and attached thereto and converging at their tops towardthe -head,.and means supporting the sheets in spaced position from the head to provide for free; thread run to the head.
