10 Claims. (Cl. 211-13) This invention relates to supporting structures for the transport of heavy articles having projecting journals. More particularly this invention relates to an improvement in frames for holding heavy spools, such as textile warp beams for transport.

Large warp beams of yarn, weighing several hundred pounds, are usually transported by train or by truck trailer. Where a plurality of beams are to be transported, it is desirable to conserve space in the transporting vehicle, to support one beam above the other. One disadvantage in such transportation has been the expense in the manufacture, storage, maintenance and return of the structures currently .available for supporting such beams during transport. It is, accordingly, an important object of this invention to provide a means for transport of such beams and similar articles which means will be light in weight, simple in construction, and efficient in use.

Another object of our invention is to provide an improved device for use in the shipping of beams of yarn and returning of the empty beams.

Further objects of this invention will be apparent from the following detailed description and claims.

The invention comprises the use of two end frames mounted on a standard beam rack.

A preferred embodiment of the invention will now be described in connection with the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same;

Figure 1 is ia front elevation of a double beam rack embodying our invention,

Figure 2 is a side View of the same,

Figure 3 is a top View of the same with one of the end frames also shown schematically in broken lines to indicate the relative position of elements of the upper frame when rotated about a nesting pin,

Figure 5 is a sectional View through line 5 5 of Figure 2,

Figure 6 is la sectional view through line 6 6 of Figure 2,

Figure 7 is an end View of the fastening plate and associated parts shown in Figure 4, and

Figure 8 is a sectional view through the line 8 8 of Figure 4.

A lower warp bea-m 12 and an upper warp beam 13 are shown supported in the dou-ble beam rack indicated generally by 14. The double beam rack 14 is composed of a lower beam rack 15 and a pair of substantially flat upper end frames, 17 and 18, which are supported on and attached to the lower rack 15 as described in detail below. The lower warp beam 12 has flanges 19 which rest on saddle members 22 of the lower beam rack. The upper warp beam 13 is supported at the

ends

26 and 27 of its shaft 28 by bearing blocks of the

end frames

17 and 18.

The lower beam rack 15 is composed of rigid upright supports, 32 supported on shoes 33 and firmly held in posij tion by rigid

horizontal members

37, 38 `and truss mem bers, 42, all of, for example, steel tubing, all interconnected in conventional manner, as by welding, to form a rigid support for the saddle members 22. In a preferred embodiment, to support a '3U-inch diameter beam rack of conventional 4 to 5 feet length the upright supports 32 would be about 21/2 to 3 feet long, their outside dimensions spaced apart by slightly more than the diameter of the supported warp beam, i.e. about 301A inches for a 30- inch diameter warp beam.

The

end frames

17 and 18, which support the upper Warp beam 13 are mirror images of each other and are composed of the bearing blocks 30 secured to rigid substantially flat panels. The bearing blocks 30 are adapted to be firmly and releasably attached to the supported warp beam shaft 28 while the lower portions of the

end frames

17 and 18 are Aadapted to be supported by and firmly and releasably attached to the lower beam rack 15 as more -fully described below.

In the preferred embodiment each

end frame

17 or 18 comprises rigid spaced

lateral uprights

52, 53,

horizontal members

54, 55, and truss members as 56, 57, 58 and 59 (see Fig. 8), all connected by conventional means, preferably welding, so as to form a rigid strong supporting structure for the bearing blocks 30. The

uprights

52, 53 may be formed of square hollow steel bars. The lower end of each upright 52 is advantageously Left open to form a U-shaped section (Fig. 5), within which is fixed a connecting device for firmly and releasably attaching said upright 52 to a nesting pin 68 xed to and projecting from the beam rack 15 therebelow. This connecting device is advantageously formed by firmly fixing within the U-shaped section of upright 52 an opened-out tube, as 61, having an inside diameter only slightly larger than that of the nesting pin 60, and spring steel snaps 62, 63, 'adjacent to and below said opened-out tube 61, which snaps cooperate with said tube 61 to releasably hold said nesting pin. These snaps 62, 63 are each firmly secured to the upright 52 by rivets 64 while the opened-out tube 61 is secured to the upright 52 by a plate 65. A plate 66, may be attached to the lower end of each member 52 for reinforcement thereof, to help to x the position of the opened tube 61, and to facilitate assembly of the double beam rack. This plate 66 is U-shaped to receive the nesting pin 60.

The lower end of each upright 53 of the

end frames

17, 18 is fitted with a sleeve 67 welded thereto (Fig. 6) for receiving snugly one of another pair of nesting pins `68 projecting upward from the lower beam rack 15. The pins 68 are identical with the pins 60, the

pins

60 and 68 being mounted at the four upper corners of the lower Warp beam rack. A plate 69, apertured to receive one of the pins 68, may be welded to the lower end of each upright 53; the plate 69 reinforces the bottoms of the uprights 53, helps fix the position of sleeve 67 and facilitates assembly of the double beam rack by acting as a shoe to lessen friction.

Each bearing block 30 (Figures 4 and 8) is lined with a layer 70 of a relatively soft and resilient material, as rubber belting, on which the end 27 (or 26) of the warp beam shaft 28 rests and which serves to distribute the weight of the warp beam from the shaft end 26 to a steel saddle 71. This saddle is supported at one end by the truss member 59 and at the other end by a cushioning filler 72 which in turn is supported by the horizontal member 54 and the

truss members

56 and 57. Each shaft end 27 (or 26) is tapped and drilled at 73 for receiving a bolt 74, which may be tted with a washer 75. The shank of the bolt 74 is removably received in a slot 76 of a plate 77 welded to the saddle 71, and the end of the shaft may be swaged so that bolt 74 cannot be readily screwed out and removed. A relatively soft and resilient lining as rubber covering 78 is desirably attached to the plate 77.

In the operation of the invention after a warp beam 12, has been placed in the lower beam rack 15, in the conventional manner, the sleeves of the uprights 53 of each of the end frames, 17 and 18, are engaged with the nesting pins 68, and the frames are swung about these pins 68, from the position shown in broken lines in Fig. 3, into the position shown in solid lines in that figure, where the end frames 17, 1S are held in position by the action of the snap springs4 62, 63. Thereafter the warp beam 13 may be lowered into position so that each end of the shaft 28 is supported on a bear-ing block 30. This may be done by placing the frame 17 under a support, as an overhead trolley, from which warp beam 13 may be supported by a sling. The bolts 74 on each end of the warp beam 'shaft 28 are then screwed tight to secure the warp beam to the

end frames

17, 18.

It is to be noted that the apparatus and procedure permit any single upper or lower warp beam to be placed in its rack without danger of contacting and thereby damaging any other warp beam in the process. Further, this apparatus facilitates placing a lower beam in a double beam rack by avoiding any damage or interference by an upper beam support, because such upper rack is readily removed out of the way until after the lower beam has been placed in its lower rack. Similar advantages occur in removing a lower warp beam from such device. .A further advantageous feature of this invention resides in that the cost of transporting the empty beam racks is substantially reduced, due in large part, to the reduction in weight accomplished by dispensing with the heavy rigid members conventionally used to connect the end frames.

There is a further considerable convenience in using the double beam rack of this invention in that the

end frames

17, 18 need not be positioned on the lower beam rack simultaneously, but may be placed thereon one at a time. Furthermore, it is necessary to align only the uprights 53 of these end frames with the corresponding nesting pins 68, the other uprights 52 being brought into position by the swinging action shown in Fig. 3 and described above.

It -is further noted that this double beam rack is inexpensive to construct, sturdy and readily adapted to be utilized in conventional carriers, which have various sizes of floor space, so as to obtain maximum ultilization of such space.

While the above apparatus has been described for use in the transport of warp beams it is also intended that this invention may be used for the transport of other large cylindrical packages such as spools of iilamentary material such as wire, sheet material such as cloth and plastic, and for the transport of other heavy articles supported by shafts.

It is to be understood that the foregoing detailed description is merely given by way of illustration and that many variations may be made therein without departing from the spirit of our invention.
