9 Claims; c1. 2 11-2 A rack of the type to which the present invention re-.

lates is shownin my Patent No. 2,601,560 granted June 24, 1952, wherein a series of jspindles' which are adapted to support rolls of carpeting thereon aremounted in vertically spaced series andare individually adjustable vertically on a pair ofhangers which are supported on an overhead track so that the rack andits lo'ad'may be moved from place to place.

In my aforesaid patent it is contemplated thatthe rolls of carpeting be mounted-on the spindles so that the carpeting may be wound on or unwoundfrom the spindle as required for displaying the carpeting and cutting off lengthstherefrom, and for this purpose thespindle may be provided, as shown in'said patent, with clamps for attaching the leading edge of the carpeting thereto for winding the carpeting on the spindle or, if thespindle is.

removable from the rack, itimay be inserted endwise through the centralopening of'the carpet rolljand locked on the spindle to rotate therewith, as shown, for example,'.

in my copending applications 'Serial'jNos. 475,186 and 475,204, now US. Patents 2,838,249, dated June 10, 1958 and 2,904,278, dated September 15,1959, both filed December 14, 1954.

Carpet rolls come from the mills in individualcrates or boxes or wrapped in burlap and it is oftentimes desirable to store the rolls in the original crates, boxes, or burlap wrappings in the same storage racks which are used for storage of carpet rolls on spindles, and accordingly it is quite advantageous andimportant that the racks be adapted to support the rolls of carpeting optionally on the spindles on which the carpeting may be wound and unwound or on shelves or palletsupon which the rolls may be laid in their original crates, boxes or wrappings;

Such adaptability is desirable for economy of equipment and space inasmuch as separate complete racks for rotatably supporting the rolls and other separate complete racks with shelves or pallets for supporting the boxed or wrapped rolls would greatly increase the cost of storage equipment and require considerable extra space, and the adaptability should be applicable to any racks with which the storage space is provided, whether the racks are suspended or floor supported, although it is especially advantageous in track supported installations, such as that of my above mentioned patent, inasmuch as the hangers thereof are rather permanently mounted and other complete racks may not be readily substituted at places in the system where it may be desired to store the carpet rolls" in the original packages.

Moreover, adaptability of individual carpet mountings of the racks for either spindle or shelf support'of the rolls is desirable-as it maybe advantageous in some cases to support, onthe'sarne rack, rolls which may be wound and unwound and also rolls in the original packages.

In the rack disclosed in my above mentioned copending application Serial No. 508,071, the spindles and their supporting brackets are removed and supporting frames having pallets or platforms thereon are substituted for supporting the. articles stationarily on the rack, whereas, in accordance with the. present invention, the spindles and their supportingbrackets are retained and the spindles rendered non-rotatable and provided with pallets or platforms thereon to support the articles stationarily.

Thus by utilizing the present invention, no dismembering of the spindle type rack is required to convert it to the. pallet or shelf type, but instead the spindles are retained and employed as the main frame for the pallets or shelves.

The principal objects of the present invention are, to

provide improved facilities by which a rack is adaptable to optionally support articlesrotatably or stationarily in' vertical series thereon; to permit the individual articles of the series to'be optionally. supported rotatably or stationarily; to retain the article supporting parts in one form, without dismantling thereof, in the converted form; to utilize as partof the stationary supporting facilities, spindles on which the articles are rotatably supported in the other formgjand in general to provide a rack with simple and inexpensive facilities by which it is easily and.

quickly convertible, and without dismantling from one form, to optionally support articles in vertical series thereon rotatably or stationarily, these and other objects being accomplished as pointed. out more particularly hereinafter and as shown in the accompanying drawings in whichz.

Fig. 1 is a front view of a rack structure with a series of articles supported thereon in vertical series some. of which are rotatable on spindles and others of which are stationarily supported on pallets mounted on spindles,

j Referring to the drawingsand particularly to Figs. 1

and 2. thereof, there is illustrated a rack structure for optionally storing rolls of material 10 on rotatable spin Thisstructure offers the adyantagethat rolls furnished in burlap orin boxes may be. individually stored away asfurnished or may be mounted on rotatable spindles, for display and ready accessibility, depending upon the Patented Jan. 19,119.50

' min more than one roll of agiv'en type of material in stock,fand in such' cases it is convenient to be able to store the unused material in itsoriginal wrapping.

,The rack structure shown in Figs. ,1 and 2, which is similar to the rack of my aforesaid patentexcept forthe addition ofjthe pallets and spindle locking facilities there-- 1 to, represents only a portion of a storage and display installation such as shown in my aforesaid patent, and in suchinstallations it has been found convenient to be able, alternatively, to store material in its original wrapping or'to display it on rotatable spindles. The number of rolls for storage and the number for display may change from day' to day, and it is important to be able to convert any particular storage rack or portion thereof from one such use to the other witho t disturbing the remaining rolls of material;

' The rack' structure consists of a track 17 frorn' which a'pa'ir' of hangers or uprights 18'are suspended for supporting a plurality. of spindles therebetweem The track 17 may be'a standard I-beam of a size suitable'for the contemplated loads and. may be supportedin an overhead position in any convenient manner which will leave the space thereunder free for storage and movement of the racks alongtthe track and will also permit free access to the racks at :any place where access 'is required. The

hangers 18, which are preferably of angle iron, are of suitable length to accommodate the desired vertical storage capacity, and each is attached at its upper 'end] to an individual trolley 19 which rolls along the opposed lower flanges of the I-beam trackt17. The hangers are suspended soas to be retained in upright positio'n,'as

for example by a bracket 21, which is secured tothe upper end of the hanger and has a horizontal flange portion, as shown at 16 in Fig. 2, which bears flatwise against the horizontal bottom face of theframe of the trolley 19 and is thus secured thereto by a pin or bolt 2 which preferably permits turning of the hanger l8 'about the ve fial axis-of: the pin or bolt '20.

type so that the spindles maybe deposited sidewise therein and lifted sidewise therefrom,rthe brackets '23 shown herein being of the open top type with a U-shaped recess 31 of suflicient depth to safely retain the spindle end therein and permit rotation thereof. Roll bearings 35 may be provided to insure ease of rotation of the spindle and a set screw 37 may also be provided for adjustment sidewise against the vspindle end toprovide a braking effect when desired. r

The spindles 11 and '15'for supporting rolls of carpeting are usually tubular lengths of pipe and the ends thereof may be plain, or when employed'with open top brackets 23, such as described above, the spindles may have a pair of annular flanges 33 welded thereon in spaced apart relation to accommodate the bracket 23 therebetween.

If the spindle supporting brackets are of the closed bearing type in which the spindles are inserted endwise into the bearing opening thereof, an annular flange like that of the flanges .33'but of loose'washer type may be slipped on each end of the spindle at the outer sides respectively. of each bracket 23 and retained thereon by a pin or bolt engaged through the end of the spindle at the outer side ofthe loosewashe'r as is explained more par ticularly hereinafter.

and 12, thereon.

In accordance with my present invention, the spindles may be rotatable in the brackets 23, as'in the ease of the spindles 11, or may be locked against rotation in the 1 brackets as in the case 'of the spindles 15, and in the latter case the spindles have one or more pallets orplatfo'rm' elements 14 secured thereon, preferably in an elevated positionithereabove for supporting articles such as the boxed or wrapped r'olls,1indicated respectively at 13 To hold the spindle against'rotation itis preferably locked at one or both ends to the hanger 18 at that end, and a particularly simple and convenient form of lock is t a hook bolt such as indicated at which is inserted "1 through and secured in diametrically opposed openings 7 39 in the end of the spindlerand provided with a hook One flange of each of the angle iron hanersfherein- V ,being threaded as indicated and having front and rear after referred to as the front'flange, provided with a vertical series of spaced openingst22 and the angle irons are oriented so that the thus apertured flanges are'in coplanarirelatidnship with one another and have the other flangesthereof, hereinafter referred to as the side'flanges,

extending rearwardly at right angles, to the plane ofthe apertured flanges. A'series of pairs of rollsupporting readilyremovable, their location on the angle irons may be adjusted to provide appropriate vertical spacing in accordance with the diameters of the rolls to be mounted thereon.

The brackets 2321s shown herein are adapted 'toi fit against the slotted flanges of the angle iron hangers are provided with two lugs 25 and 26 projecting from the at one end thereof remote from the spindle as indicated at 41 which is engaged in a notch 38 provided therefor at an appropriate place in the'rearedgeiof the side flange of the hanger 18 at that end of the spindle, the bolt 40' nuts 29 and 30 thereon, the former'of which serves to clamp and hook end 41 of the bolt securely in the notch 38 and'the latter serves as a lock nut to retain the bolt' securely against displacement from the locking position.

In such racks it is customary to provide the spindles thereof with facilities at the ends for attachment of a crank or some other means thereto by which the spindle rotatable, as shown and explained in my above mentioned Patent'2,60l,560, and it is also'desirable, in some back thereof and adapted to engage, respectively, any pair of adjoining slots of the angle iron; The. upper lug is formed with' a depending portion 27. which, when the lugs 25' and 26 are inserted in the adjacent slotsil and 1 the bracket slid downwardlyt'until' thelugs engage the lower: ends of the respective slots, will contact the rear portion 28 of the flange between the engaged slots in a hook-like manner and thereby lock the bracket onto the angle iron; Thus theibfrackets may bereadily removed and locate'dtat any adjoining pair ofopenings throughout the length of the angle'irbnJ I e The brackets 23 maybeof any appropriate construction with hearing openings or seats therein'..to1support the e opposite ends of the spindles rotatablyt therein, and pref;

91 m re? e e s r l s? 7 ee cases as explained above, to provide at theoutcr side of each bracket 23 a loose washer, similar to the above mentioned flanges 33 and to retain such loose washer on the spindle end bya pin or bolt, and as diametrical lioles 39 are oftentimes provided inthe spindle ends to accommodate a pin or bolt which is engageable by the crank or other means for rotating the spindle and also utilized for retaining such loose Washer on the spindle, the above described hook bolt 40 for locking the spindle against rotation is particularly convenient as it may be secured to, the spindle ends in the same holes 39 that are provided for the pin or bolt by which the crank is attached and by which the washer is retained on the I spindle end. J

The notch 38 in which thechook boltf40 engages is preferably at the level of the axis ofthe spindle in the brackets 23 in which the spindle is to be locked so that the bolt 40 extends'horizontally sidewise from the spindle end 'as shown in Fig. 7,v.an'd;ta series of such uotehes 38 is provided throughoutfthe length of,each

hanger 18 with the notches of each series arranged re? spectively. at successive levels corresponding to the various different levels of adjustability of the brackets 23 along the hangers, so that at any position of adjustment of the brackets 23 on the hangers, the spindle in the thus adjusted bracket may be locked against rotation and in the same manner shown in Figs. 6 and 7.

With the spindle fixedly mounted in the manner above explained at any selected elevation along the hangers 18, one or more pallets 14 are secured on the thus fixedly mounted spindle, as shown particularly in Figs. 3, 4 and 5, each by a pair of clamping brackets of pipe clamp type which are indicated as a whole by the reference numerals 42.

Each said bracket 42 comprises an upper half clamp 43 and a mating lower half clamp 44 each of which has ears 45 at the ends through which bolts 46 are engageable to clamp said parts 43 and 44 on the spindle 15, and each upper clamp part 43 has a plate-like riser 47 integral therewith and extending upwardly therefrom for attachment of the pallet 14 thereto and to support the pallet at an elevation above the spindle 15.

The pallet 14 has a pair of laterally spaced cleats 48 on the underside located respectively near the opposite ends thereof and each cleat 48 is a short length of angle iron with one flange thereof secured to the underside of the pallet and the other flange extending downwardly, as shown in Fig. 5, and each downwardly extending flange is secured midway of its length, by rivets or bolts 49 or in any other convenient manner, to the upper end of a plate-like riser 47.

Thus each pallet 14 has a pair of clamps 42 thereon by which it is fixedly secured on the spindle 15 and these pallets may be adjusted lengthwise of the spindle to any desired location thereon.

Fork lifts are usually employed to load the rolls on the racks and to remove the rolls therefrom and two pallets 14 are preferably employed on each spindle 15 and spaced apart to accommodate the fork 34 of a fork lift therebetween at a place central of the length of the roll and the risers 47 are of such vertical extent to hold the pallets 14 at a suflicient elevation above the spindle to accommodate the fork 34 of the fork lift between the spindle and a roll on the pallets 14 as shown in Figs. 1 and 3.

Thus a spindle type rack, such for example as that of my aforesaid Patent 2,601,560, may be converted at any storage location thereon to support an article, such as a roll of carpeting in its shipping box or wrapping, stationarily and without any dismantling of the spindle type rack by merely locking the spindle at that location against rotation and utilizing the thus locked spindle as the sup porting frame member for one or more pallets which are conveniently and securely mountable on the locked spindle.
