a Claims. (Cl. 242-553) In various establishments, such as rug and carpet mills, mills in which upholstery and other fabrics are woven, and the like, it is necessary to store, in large, heavy rolls, quantities of the various fabrics manufactured.

Continual work must be done on the various rolls, as for example, samples must be cut therefrom, used rolls must be replaced, discontinued items removed, and new itemsadded.

Due to the weight and size of the rolls (carpeting man-- ufacturers, for example, usually maintain said rolls in diameters of 30 inches and in lengths corresponding to the carpet widths, as for example 27 inches) it is difiicult to handle the rolls with ease, and considerable damage'theretooften results. Further, difi'iculties are experienced in storing the rolls in a minimum area while still providing sufiicient working area for allowing the cutting of material from any selected roll.

The present invention has as its main object the provision of a rack assembly for rolls of the type referred to, which assembly can be erected in a storage room, warehouse, cutting room, or the like, and which will be so designed as to facilitate the handling, cutting and storage of the rolls in a small area.

Another object of importance is to provide an assembly as described which will permit any roll to be swung outwardly from a position along a corridor, into a position in which it extends transversely of the corridor in a location that will facilitate the rolling of a work table or the like thereunder, whereby to permit a piece of material to be cut from a roll.

Another object is to permit the rolls to be swung inwardly and outwardly as desired, without their interfering with rolls adjacent thereto.

Yet another object is to so design the rack as to permit the rolls to be loaded thereon or removed therefrom by conventional load handling apparatus, such as an industrial truck, thus to permit the movement of the rolls onto and off the rack to be accomplished with a minimum of difiiculty.

Yet another object is to so design the rack as to cause the roll to be automatically shifted longitudinally of a spindle on which it is rotatable, so as to project well into the work corridor where it will not be interfered with by rolls lining the sides of the corridor, and where it can be readily worked upon.

Another object is to cause the roll to be retracted upon its spindle in an opposite direction responsive to swinging of the roll back into a position in which it extends along the side of the corridor.

Still another objeect is to include, in association with the roll, protective or stop arms that will swing upwardly into a position adjacent one end of the roll, to prevent accidental movement of the roll off its associated spindle.

Other objects will appear from the following description, the claims appended thereto, and from the annexed drawings, in which like parts are designated by like reference characters throughout the several views, in which:

Figure 1 is a side elevational view of a series of the racks, as they appear when lining one side of a work corridor, portions of said series at the ends thereof being broken away;

Figure 2 is an enlar ed top plan view, portions of the rolls being broken away;

Figure 3 is an enlarged side elevational view of one of the racks, the roll being shown in section, a portion of the main post being broken away; 2

Figure 4 is a detail longitudinal sectional view, the scale being still further enlarged, on line 44 of Figure 3, the dotted lines showing the rack and roll in extended position;

Figure 5 is a detail sectional view, the scale being enlarged still further, substantially on line 5-5 of Fig ure 4; and

Figure 6 shows a double series of racks lining the sides of adjoining corridors and both sides of a single corridor.

The reference numeral 10 has been applied generally to a main post. As shown in Figure l, in a typical installation, a plurality of the main posts would be erected in a straight line, at opposite sides of an elongated, corridor-like working area, so as to in efiect define the corridor, a plurality of said corridors being disposed side by side, with each rack being common to the corridors at opposite sides thereof.

In Figure 1, there is shown an installation, in which a lower, horizontally extending row of rolls R are supported, with a pair of the lower rolls being disposed between each pair of adjacent main posts it), and wherein there is also an upper row or line of rolls, spaced above the respective lower rolls, thus causinga total of four rolls to be disposed between each pair of main posts 10.

It will be understood, in this regard, that instead of two vertically spaced, horizontally extending rows, there could be more than two, or if desired only one row.

In any event, in the illustrated arrangement, eachmain post It is provided with upper and lower pairs of C-shaped hinge support arms 12. The several arms 12 are all identical, with the arms of each pair being arranged oppositely to one another. Each arm includes short, horizontally extending end portions fixedly secured to the main post 16. The bight portion 14 of each arm (Figure 5) is of reduced diameter relative to the end portions 12, and is fixedly connected to said end portions by a flared portion 16, serving as a race for ball elements 18 engaging opposite ends of a sleeve 2 .5, that is circumposed about the bight portion 14 and is rotatably mounted upon and spaced from said bight portion by the ball elements.

Integral with each sleeve 21' medially between the ends of the sleeve, is an elongated, horizontally extending, tubular spindle 22, which, due to the rotatable mounting of the sleeve 29, is swingable in a horizontal plane about the axis of the bight portion 14, between the retracted and extended positions thereof shown in full and dotted lines, respectively, in Figure 4.

Each spindle 22, for the greatest part of its length, is reduced in diameter as at 24, thus defining, at the inner end of the reduced portion, a circumferential stop shoulder 25 spaced closely from the inner end of the spindle.

An elongated roll support sleeve 26 receives the reduced portion 24 of the spindle, and at one end abuts against the shoulder 25. Said one end of the support sleeve 26 has a set collar 23 thereon, the collar 28 being fixedly secured to the sleeve end about which it extends to provide an abutment upon the sleeve. 7 Engaging against the .set collar28 is a ring 39, and formeduponthe ringare spaced, radially and outwardly extending ears 31. v e 1 A roll shield plate 32 has a center opening receiving the inner end portion of the support sleeve 26, and inr the support sleeve while still permitting rotatable movement of the support sleeve within the ring.

Extending between the cars 31 of each ring 39 is a pivot pin 36, passing through one end of a roll shifting link 38, the other end of which is pivotally connected at 40 to the outer end of a projection 42 fixedly attached to and extending radially and outwardly from the main post 10. At opposite sides of each projection 42 there are provided oppositely facing stop blocks 44 each of which has a concave outer face in which is mounted a complementarily convexed rubber pad or cushion 45. The cushions 45 are so disposed as to engage the inner ends of the spindles 22 when said spindles are swung to their dotted line positions of Figure 4.

Mounted in a circumferential series of openings formed in the inner end portion of support sleeve 26 adjacent the circular, flat shield plate 32 are ball elements 46. These project radially inwardly of the support sleeve 26, into rollable engagement with the adjacent surface of the reduced portion 24 of the spindle. In this connection, adjacent the other end of the support sleeve, a similar circumferential series of openings is formed in the reduced portion 24, and mounted in these openings are ball elements 48 projecting radially outwardly of the spindle into rollable engagement with the inner surface of the support sleeve 26.

By reason of this arrangement, each support sleeve 26 is mounted upon its associated spindle not only for rotation, but also for sliding movement longitudinally of the spindle'to the position shown in dotted lines in Figure 4. The ball elements 46, 48, of course, reduce friction in both of these movements of the support sleeve relative to the spindle.

Due to the provision of one series of ball elements on the support sleeve, and the other series of ball elements on the spindle, the support sleeve is spaced properly from the spindle in all positions of said sleeve, whether the sleeve is rotating thereon or is being shifted longitudinally thereof, there always being both annular series of ball elements in proper engagement with the support sleeve and spindle respectively even when the support sleeve is almost fully extended beyond the end of the spindle.

The outer ends of the support sleeves 26 project beyond the outer ends of their associated rolls, and in the retracted positions of the rolls are received in semicylindrical support housings 50, mounted upon and extending outwardly from auxiliary posts 52, one of which auxiliary posts is medially disposed between each pair of adjacent main posts 10.

Adjacent the support housings, stop arms 54 are mounted pivotally at their inner ends upon the support sleeves, there being a pair of diametrically opposed arms 54 on each sleeve adjacent the outer end thereof. The arms 54 can be swung to positions in which they are recessed in slots 56 formed in the sleeves, and in the recessed positions of the arms 54, they are held against movement radially outwardly of the sleeve to the dotted line positions of the arms shown in Figure 3, by the walls of the housings 50. However, spring means 55, in the form of leaf be cut from a particular roll, the worker would generally move a rollable table T (Fig. 6) along the corridor until it is abreast of the roll to be used. The selected roll is then grasped and swung outwardly from its full line position of Figure 4, to its dotted line position in this same figure.

When the roll is swung outwardly, the link 38 associated therewith will exert pressure against the adjacent shield 32 in a direction to the right in Figure 4, that is, toward the outer end of the spindle. This will shift the sleeve 26, together with its associated set collar 28, shield 32, and roll R, bodily longitudinally of the spindle, to the dotted line position of Figure 4. The purpose of this arrangement is to cause the roll to be projected well into the working corridor, where other rolls lining the sides of the corridor will not interfere with free rotation of the selected roll.

in its working position, the roll R extends directly across the corridor, the roll thus swinging through 90 degrees from its retracted to its extended position, ,while at the same time being shifted longitudinallyof the spindle while 7 traveling between its retracted and extended positions.

With the roll swung outwardly, it will be disposed above the working table, and the worker can now rotate the roll with its associated sleeve 26 of the spindle, to remove a selected amount of material. 7

When the roll is to be returned to its retracted position along the side of'the working corridor, the stop arms 54 are forced back into their'recessed positions, and the spindle 22 is swung about its hinge axis back into its full-line position of Figure 4.

The construction also facilitates the removal or replacement of rolls. Assuming, for example that it is desired to place a roll upon a spindle, using an industrial truck, the truck can be driven up to the rack, with the spindle extending outwardly in the dotted-line position of Figure 4 or in an intermediate position. The rolls are generally supported upon spindles on the elevatable hoist of the industrial 'tl'IlCk, and the hoist spindle, when'aligned with the spindle 22, can be properly disposed for sliding the roll onto the sleeve 26.

In Figure 6 there is shown an installation in which series of horizontally extending rows of rolls R arranged in pairs in side-by-side relation to be disposed between spaced pairs of a row of main posts, generally indicated at 10, with corridors defined between the rows of main posts- Thus, the double rows of rolls R line the sides of adjacent corridors and line opposite sides of each corridor so that a selected roll R may be swung into the corridor along which it is arranged for better utilizationand'conservation of floor space. This will enable a worker to move the table T along a corridor lined upon opposite sideswith superimposed rolls R and move a selected roll from either side of the corridor to perform work on the fabric wound into the rolls R, as schematically shown in Figure 6. r

It is' believed apparent that the invention is not necessarily confined to the specific use or uses thereof. described above, since it may be'utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated springs tensioned to spring radially outwardly of the rotation and for movement and described, since such construction is only intended to be illustrative of the principles of operatiou'and the means presently devised to carry out said principles, it

being considered that the invention comprehends. any minor change in construction that may be'permitted within the scope of the appended claims. a
