United z s tates Patent ROTARY sPooL RA'CK V Bernard H. Best, 12 Ram: Drive, Plainview, N.Y.

Filed Au 7,195, Ser. No. 832,539 '2 (Cl. 242 -139 This invention relates ,to a novel rotary rack for hold- 20, to the extent necessary to obtain the desired overall quickly iand easilyureached and removed from the' pins for use.

Another object of the invention is to provide a device of the character indicated above whose drum is longitudinally extensible and contractible, so as to accommodate the drum tobeing mounted on and between supports which are spaced at different distances from each other, such as the side panels of difierent size drawers or differently spaced mounting brackets, and to accommodate a greater or less number of spool-supporting pins.

A further object of the invention is to provide a device of the character indicated above wherein the drum is composed of telescoped sections which are formed with pin retaining holes, in which pins are adapted to be removably and securably engaged, certain of the holes in the two sections, and related pins, being utilized as means for securing the sections relative to each other in adjusted positions.

A still further object of the invention is to provide a rugged and serviceable device of the character indicated above which is uncomplex in construction, is composed of a small number of simple and easily made parts, and which can be made in attractive forms, at relatively low cost, from a variety of suitable metallic and non-metallic materials. A

Other important objects and advantageous features of the invention will'be apparent from the following description and the accompanying drawings,.wherein,' for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

Figure 1 is a contracted and fragmentary top plan view, partly in section and broken away, of a device of the invention;

Figure 2 is an end elevation of Figure 1, broken away to show drum structure; and

Figure 3 is an enlarged fragmentary section taken on the line 33 of Figure l.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated device, generally designated 10, comprises an axially elongated hollow drum 12, made of metal or plastic, having limited resiliency andhaving substantial rigidity, comprising an inner preferably tubular section 14, having an open inner end 16 and a closed outer end 18, and an outer preferably tubular section 20, having an open inner end 22 and a closed outer end 24. The inner section 14 is slidably telescoped into the outer section length for the drum 12. I

The closed

outer ends

18, 24 of the sections 14 and 20 are formed with thickened bosses 28, respectively, which preferably extend axially inwardly in the sections, the bosses being formed therethrough with smooth axial journal bores 30, which extend to shanks 34 of related mounting screws 36 and 38, respectively, which are threaded in supports located at the opposite ends of the drum 12. I p

The side walls 40 of the drum sections are formed with preferably circular holes 42 which are arranged in circumferential rows, and in staggered longitudinal rows, as shown in Figures 1 and 2. Spool holding pins 44 are removably and securably engaged in the holes 42.

*As shown in Figure 3, the pins 44 preferably comprise elongated hollowbodies46 having closed inward end portions' or plugs 48 of substantial cross section, which are substantially plane cylindrical in form, and which are of a diameter to make frictional engagements in the drum holes 42, suflicient to preclude the pins being pulled out by the weight of sewing thread spools 50 engaged thereon or b'y-thepullexerted on the pins by removal of spools therefrom while'providingforf manual disengagement of the pins from the holes, when necessary. The plugs 48 can, for this purpose, be somewhat outwardly tapered from a diameter slightly larger than the holes 42, so as to achieve a plug fit when inserted in the holes, or the plugs can be left with or provided with, in the course of their manufacture, roughened exteriors so that the plugs grip the edges of the holes, some reliance for retention of the plugs in the holes being made on the resilience of the drum side walls.

The pins 44 have relatively thin and resilient, circular side walls 52, which extend outwardly from the plugs 48, and are belled intermediate their ends, as indicated at 54, and having a slight outward taper to their outer ends 56, to a diameter easily insertible in the bores'58 of thread spools 50, with the belled portion 54 being larger in diameter than the spool bores 58. The pin side walls 52 have therein circumferentially spaced longitudinal slots 60 which extend from the outer ends 56 of the pin bodies 46 to points near to and spaced from the plugs, as indicated at 62. As indicated at 64, the inner ends of the belled side Wall portions 54 are larger in diameter than the holes 42, so as to serve to prevent too far insertion of the pins in the holes 42. Engagement of spools 50 over pins 44 contracts the belled portions 54 of the pins and tensions these portions of the pins against the sides of the spool bores 58 so as to releasably secure the spools on the pins.

While various brackets and support elements can be used, in conjunction with the screws 36 and 38 at opposite ends of the drum 12 for operatively and stationarily supporting the drum, the invention concerns primarily the installation of the drum in a drawer 66, of such as a sewing cabinet (not shown), the drawer having

side panels

68 and 70, through which the screws 36 and 38 are severally threaded, as seen in Figure l, with the drum 12 positioned close to the front end panel 72 of the drawer. This arrangement provides for protective, spacesaving concealment of the device, while providing ready accessibility thereto.

As shown in Figures 1 and 3, the plugs 48 of the pins 44 are long enough, so that when engaged through holes 42 in the outer drum section 20, the plugs can engage in holes in the inner drum section 14, for holding the drum sections in longitudinally adjusted relation to each other.

Although there has been shown and described herein a 7 preferred form of the invention, it is to be understood that the invention is not necessarily confined thereto, and that 2,944,761 Patented July 12, 1960 any change or changes in the structure of and in the rela- 1.
