12 claims. (Cl. 2112-15) vThe `present inventionA relates to shipping or storing racks for a single yarn iilled spool o'r beam.
In the past, yarn beams or spools having layers of continuous yarn end s would thereupon have generally been shipped in beam racks which are designed to accommodate a plurality of Iyarn beams. A filled yarn beam weighs approximately 1,000 lbs. When several of these beams `are placed within a multiple beam containenthe whole assembly weighs several thousand pounds. This weight factor reduces themaneuverability of the 'racks which complicates loading and unloading operations when `shipped to customer converters'who 'use ythe 4yarn in the knitting 'or weavingfof fabrics. The converter also nds it difcult to move the iilled beam racks to desired locations for storage or use on his premises. In addition, the converter or customer may order only one yarn 'filled beam, in which event, a single beam will be AshippedV in a large rack 'designed to contain aplurality of beams. Both the yarn beam shipper and converter have long desired lighter and more maneuverable beam racks which can be `easily handled.
It is therefore one object of our invention to provide compact, novel and improved shipping or storing 'racks which willfaccommodate a single yarnlled beam and which can be easily maneuvered.
It is a-further object of our invention to provide novel and improved single yarn beam racks having novel beam locking or anchoring devices for locking a beam lirmly in place within the rack. Y
lt is still a further object of our invention to provide novel and improved single yarn beam racks which have stacking or tiering guides Iwhereby one beam rack may be easily positioned atop another rack for storing or shipping.
Still another object of oui' invention is to provide novel and improved 'yarn beam Vracks having novel and improved speciiic locking devices for locking in place an upper beam rack positioned atop a lower rack.
`Other objects and advantages will become more apparent from a study of the following description Land drawings wherein:
Figure 1 is a perspective of a single yarn beam rack;
Figure'Z is an enlarged detail of the beam stops incorpotrated with the rack of Figure 1; v y
Figure 3 is an end view of a modification of the rack ofmFigure l; n Q l d n n Figure 4 is an enlarged detail of the locking means for holding in place a beam rack as shown in `Figure 4 atop a similar rack. n n
Figure 5 is an end vview of another `modification of the rack 'of Figure l; and l Figure 6 is an enlarged detail of thebeam locking means for the rack of Figure `5.
Briefly, our invention comprises a rectangular metal frame or rack which has locking means for` holding a yarn beam rmly in 'place within the rackt Tiering or stacking guides vare aliixed to ,the beam racks or frames whereby one beam rack may be easily stacked atop an- ICC other rack. With certain 'of therack modilication's, additional locking means are provided for holding in yplace one rack positioned atop another. v A
Referring now to the drawings and more particularly to Figure 1 wherein is shown a preferred embodiment of our rack for supporting a flangedyarn beam, the 'metal Arack or frame A for supporting a lled yarn vbean'i or spoel 1 comprises vertical corner legs 4, 4, upper and lower longitudinal supports 6, 6 welded 'toth'e legs directly and also connected with the legs through struts 6', and 'ripper 'an lower transverse end supports 8, Sfwelded to the legs 4, 4. Cross braces 9, 9 extend between and are affixed to the lower longitudinal supports 6, 6 to strengthen the frame or rack A., Beam supporting tracks 1'0, 10 also extendbejtween and are aixed to the lower longitudinal supports adjacent the ends of the supports. The tracks 10, -10 sup,
port the beam flanges 1', 1 of the yarn beam 1. Checks 11 which have arcuate shaped faces are bolted to the back i end of the tracks 10, 10 and back up or further support the beam flanges 1.', 1 vto correctly position the beam within the rack A. `To lock the beam -1 `in position within the rack A a turnbuckle assembly 12 is pivotally secured y. to the chock end of each track 10,10. The turnbucklesj 12 are positioned over each end ofthe beam shaft 14 `and when the bolts 15 are tightened against the ends of shaft 14, vthe beam is firmly lo'cke'd in plae within the rack A.
An important feature of our invention is that two `or three of the racks A may be stacked one atop the other to conserve Vspace when shipping or storing the racks. As seen in Figure l of the drawing, rack stacking guides or pipes 16, 16 are weldedl to each leg 4, 4 of the rackA A the bottom rack as will be explained.` When in position i the legs 4, 4 of the upper or second rack will rest upon the corner plates 118, 18 ofthe bottomV rack. A pair of skid legs 27, 27 'for the rack A are welded to the bottom of the longitudinal and transverse frame members 6, 6 and 8, 8 -and to vthe rack legs 4, 4 forming a corner with each leg 4. Whenl stacking one rack A atop a bottom rack A, the corners formed by the skid legs r27, 27 cooperate or contact the guides at one or theA other end of the rack A to .guide or center, as the top rack 'is being flowered, the contacted corners 18, 18 of legs 4, 4 of the 'rack being lowered onto the corner vplates Y18, 18 of the bottom rack A.l T he corners formed by the skid legs at Athe opposite end o f the upper rack will necessarily follow into .position the bottom of the longitudinal members 6, 6, of the upper frame A, t snugly against the complementary angularly descending end portions vof the upper longitudinal finembers 6, 6 of the bottom -fra'me A to longitudinally lock the racks together. The guides 16, 16 also actto prevent transverse `and vlongitudinal movement between the 4'stacked racks.
As seen in Figures 1 and 2, beam stops 30, 30 'extend through the vertical face of tracks 10, 10 nea'r the front or vopen end of the tracks. The beam stops prevent the beam from rolling oif the front end of the tracks 10, -10 when the turnbuckle locking assemblies 12 are removed from the ends of the beam shaft 14. As seen invFigure 4v2 of the drawings, the stop `assembly 30 comprises a slotted and preferably cylindrical Vshaped casing Y33 closed iat 4one end. The open end of the casing is threaded into a look nut 35 which nut is welded in place over a hole through the vertical face of track 10. A spring 37 and a latch b'olt38 are positioned within the casing 33 with the free end of the spring contacting the end of the casing. A pull pin 43 extends through slot 45 of casing 33 and is threaded into a hole in the latch bolt 38. As seen in FigureV 2, the slot 45 extends downwardly at its outer end whereby the pull pin 43 may be seated after the operator has pulled the pin backward to draw the latch bolt 38 back into the casing. When the pin 43 is in its seated psition,[the free end of the bolt is flush with the vertical face of the track thus permitting the beam 1 to be rolled along the tracks 10, 10 to be removed from the rack A. The beam 1 is preferably loaded and unloaded through the front of the rack A.
A modification of the rack A of Figures Vl and 2 of the drawings is shown in Figures 3 and 4 of the drawings. The frame structure of the modified rack B is similar to that of rack A. A turnbuckle locking assemb ly 12 is pivotally secured to the vertical face of each track 10 at the center of Vthe track. The turnbuckle assemblies 12 fit over the ends of the beam shaft 14 to firmly lock the beam 1 in position within the rack B. A pair of identical chocks 50, 50 which support the beam anges 1 are also aixed to each track 10, 10 at positions whereby they will retain the beam 1 at the center of the rack A. With this arrangement, the beam 1 is firmly locked in place withinV the rack B. lThe beaml 1 in this instance is loaded `and unloaded through the top of the rack B.
A'stacking or tiering Vguide in the form of an angle plate 55 is afiixed to each of the two upper transverse rack end members 8, 8. The guides 55 are diagonally opposed to one another being affixed to opposite ends of the transverse members 8, 8. Braces 57, 57 extend downwardly from the transverse frame members 8, 8, at an angle and are Welded directly to the bottom edge of the corner leg 4. When one of the racks B is lowered atop a'bottom rack, the sloped outer surface of the angle plates 55 guide the braces 57, 57, so that the corner legs 4, 4 of the top rack B will rest directly upon the lower rack struts 59, 59 which are somewhat similar to the struts 6 of the Yrack of Figure l.
To lock an upper beam rack B in placewhen positioned atop a similar bottom beam rack, the racks have a pair of stacking or locking devices 60 (Figures 3 and 4). One locking device 60 is alixed to each upper transverse rack end member 8 at oppositeends of theY transverse members so that the devices 60 are diagonally opposed. As seen more clearly in Figure 4 of the drawing, a latch bolt 70 is slidingly mounted within a supporting frame 73 afiixed to the upper transverse rack end member 8. A spring 75 is positioned around the bolt 70 and is confined between the back vertical plate 76 of frame 73 and a collar 78 secured to the bolt '70. The forward movement of the collar 78 is restricted by a stop member 79 through which the bolt 70 passes and which is Welded within the frame 73. The end of the |bolt extending beyond the end plate 76 of frame 73 terminates in an offset or release handle H which, when pulled by the operator will draw the bolt 70 back within the frame 73. A stop pin 82 afiixed to the inside of the transverse rack end member 8 retains the bolt in its withdrawn position when the handle H is swung in position behind the pin.
As seen in Figures 3 and 4, the braces 57, 57 extending downwardly from the transverse rack end members 8, 8 have holes 85, 85 drilled therethrough so that when one rack is stacked atop another, the latch bolt Vwhen released will extend through the hole 85 of the brace 57 afiixedvfto the top frame. The compressed spring 75 forces the latch bolt 70 forward Iwhen the handle H is pivoted off of the stop or retaining pin 82. Y With this arrangement, an upper beam rack B may be firmly locked in place atop a bottom rack B.
A further modification of the rack A is shown in Figures 5 and 6 of the drawing. As seen therein, the rack T 4 C has longitudinal members 90, which are bracket shaped, and are welded to the top vot the frame legs 92, 92. The beam supporting track 10 and chock 8 arrangement are the same as that for the rack shown in Figure l ofthe drawings. A beam locking assembly 96 affixed at each end of the rack C locks the beam 1 in place within the rack. As seen more clearly in Figure 6 of the drawings, the locking assembly 96 comprises a metal plate 98 which is pivotally mounted at 99 to each upper transverse rack end member 100. The free end olf the plate 98 is of arcuate shape whereby the plate rests upon and conforms with the curvature of the beam flange 1. The plate 98 has a hole 98 drilled therethrough. A block 102 having a holeV 102 cut therethrough is welded to the top` surface of the plate 98 at the free end of the plate so that the holes 102 and 98' are in alignment. A threaded lock bolt 104 operates Within a casing 106 which is pivotally mounted at 107 to the fron-t end of the transverse rack member 100. The free end of the bolt 104 terminates in a short stud 109 of a smaller diameter than the threaded portion of the bolt. A nut 108 is threaded over the free end of the bolt 104 and welded in place thereupon. The nut 108 has holes Vdrilled through its opposite tfaces which holes are in alignment with drilled holes in the bolt 104. A turn rod is inserted through the nut 108 and the bolt 104 to rotate the bolt. To wedge or tighten the plate 98 against the beam flange, the turn rod 110 is rotated in a clockwise direction whereupon the nut 108 is pressed or wedged against the block 102 and plate 98 to firmly impress the platte upon the beam flange 1 to lock the beam in place within the rack C. The stud 109 passes into the holes 102' and 98 of the block 102 and plate 98. This operation is repeated with the locking device 96 at the opposite end of the rack C. The beam 1 is loaded and removed from the rack C through the front of the rack. With this arrangement, the beam is locked in place with the diametrically opposed chocks and locking devices applying pressure to the forward and back pontions of the beam flanges.
The tiering, stacking and locking devices used with this modification are similar to those used in the rack modification shown in Figures 3 and 4 of the drawings. The release handle H' is slightly modified, and the stop pin 82' is positioned in the upright position rather than the horizontal position. A locking device 60 is mounted within each upper bracket shaped longitudinal rack members 90 at opposite extreme ends whereby the devices 60 are diagonally opposed on the rack C. The latch bolts 70 cooperate with holes 112 in the corner legs (Figure 5) to lock in place an upper rack C positioned atop a lower rack C. When the two racks are stacked, the legs 92, 92 of the top rack are supported bythe bracket shaped longitudinal rack members 100,100 of the bottom rack C.
It is to be understood that additional modifications of the beam racks disclosed above may be made without departing from-the scope or spiritrof my invention as defined in the appended claims.
