- ABSTRACT A combination lifting/bracing rod structure, for use with heavy rolls of easily damaged material wound on tubular cores, is disclosed.
- Each such rod structure includes an elongated rigid bar or rod having a peripheral flange at one end, and a cylindrical sleeve slidably mounted on the rod, the sleeve having a peripheral outwardly directed flange at that end thereof facing away from the flanged end of the rod.
- the sleeve carries a set screw to enable it to be locked to the rod in any selected adjusted position.
- This invention relates to combination lifting and bracing rods to be used in connection with the transfer, from one location to another, of heavy rolls of easily damaged material wound on tubular cores.
- Tire cord fabric is usually produced in the plant of the fabric manufacturer in the form of large rolls wound onto flangeless tubular cores. Each such roll, which, especially after the fabric has been dipped and hot-stretched, will normally weigh from about 1,700 to 2,000 pounds, is sealed in a polyethylene liner to protect it from moisture, ozone and other pollutants. For added protection, there is also wrapped about the liner a 0.080 inch thick Mead paper board covering which is fastened to the roll by heavy metal or nylon strapping. Until the fabric is to be used, of course, for example by a tire manufacturer, the packaging must be kept intact, to protect the fabric against damage both to its quality and to its physical properties.
- the aforesaid method of handling tire cord fabric rolls has certain disadvantages, however.
- the forks of the lift trucks frequently gouge or tear holes in the protective wrapping, and sometimes even penetrate and cut through a number of the outermost layers of the fabric roll to a depth of as much as 4 or 5 inches into the roll. This renders substantial amounts of the fabric unfit for use in tire manufacture.
- the forks of the lift truck do not penetrate into the fabric but merely break the polyethylene liner, at least the outer layers of the fabric are exposed to pollutants in the air and are rendered unfit for use in tire manufacture.
- Tire cord fabric as produced is between about 56 and 60 inches wide and is wound on tubular cores ranging from about 63 inches in length for a roll of textile fiber cord fabric to about 66 inches in length for a roll of metal wire cord fabric. Since the rolls are loaded into a shipping vehicle in transverse relation thereto, it is necessary to prevent any axial movements of the rolls relative to one another and to the vehicle, to prevent one roll from tearing the protective wrapping of another roll, and to avoid the risk of unbalancing of the vehicle while it is in motion. To this end it has heretofore been conventional to insert a pair of disposable wooden brace sticks into the opposite ends of each tubular core.
- brace sticks are such as to leave, upon loading of the respective roll into the vehicle, a small clearance of of about 1 inch between each stick and the proximate wall of the vehicle, and a heavy nail is driven into each brace stick just outside the proximate end of the core to prevent any further entry of the stick into the core.
- Such brace sticks are, of course, inserted into each roll core before the same is loaded into the vehicle. Thus, the rolls are not completely braced.
- the brace sticks are usually sawed off at the end of the trip to facilitate unloading of the vehicle. since they are not sufficiently strong to serve as lifting adjuncts for the rolls. This has created yet another source of waste adversely affecting the economics of tire manufacture.
- the combination lifting and bracing rod structure includes an elongated rigid, preferably metal, bar or rod having a peripheral flange at one end, and a concentric sleeve slidably mounted on the rod, the sleeve having a peripheral outwardly directed flange at that end thereof facing away from the rod flange.
- the diameter of the rod is somewhat less than the inner roll core diameter so that the unflanged end of the rod can be easily inserted into the core, and the outer diameter of the sleeve flange is some what greater than the inner roll diameter so that the sleeve can be abutted against the core.
- the sleeve carries a set screw the tip of which protrudes through a hole in the sleeve so as to be engageable with the surface of the rod to enable the sleeve to be locked to the rod in any desired adjusted position.
- the rod is also provided with a radial protuberance, for example a spot weld, at its un- 3 flanged end, the height of which is sufficient to prevent the sleeve from falling off the rod when the latter is not inserted into a roll core, but is insufficient to interfere with the insertion of the rod into the roll core.
- each combination preferably having the unflanged end of its sleeve abutted against the rod flange, are inserted into the opposite ends of the roll core until the flanged ends of the sleeves abut against the respective ends of the roll core.
- the portions of the rod/sleeve combinations located extemally of the roll core ends can then be engaged by a bifurcated adjunct of or attachment to a fork lift truck to permit the roll to be lifted without the forks engaging the roll covering or the fabric.
- the rods are moved axially outwardly (after loosening of the screws.
- the rod/sleeve combinations serve to brace the roll fully against axial movement in the vehicle.
- the rod/sleeve combinations are simply returned to their starting states by loosening the set screws and pushing the rods axially inwardly. The rod/sleeve combinations then again are able to serve the lifting function previously referred to. When no longer needed for the handling of that roll, the rod/sleeve combinations are simply removed from the roll core and can be used and reused in handling other rolls.
- FIG. 1 is a side view, partly in elevation and partly in section, of a combination lifting/bracing rod according to the present invention
- FIG. 2 is an enlarged fragmentary perspective view of the lifting/bracing rod shown in FIG. 1;
- FIG. 3 is an exploded perspective view of a roll of tire cord fabric equipped with a pair of combination lifting/bracing rods according to the present invention
- FIG. 4 is a fragmentary sectional view taken along the line 44 in FIG. 3 and shows the lifting/bracing rods in the lifting attitude thereof;
- FIG. 5 is a sectional view similar to FIG. 4 but shows the roll in a vehicle and the lifting/bracing rods in the bracing attitude thereof;
- FIG. 6 is a perspective view of a bifurcated hookended lifting attachment for a convention al lift truck by means of which the latter can be rendered capable of lifting and carrying a tire cord fabric roll equipped with lifting/bracing rods according to the present invention.
- the combination lifting/bracing rod structure 10 (FIGS. 1 and 2) according to the currently best embodiment of the present invention includes an elongated rigid metal bar or rod 11 and acylindrical metal sleeve 12 (for example a length of pipe) slidably mounted on the rod.
- the rod 11 When intended to be used in the handling of rolls of tire cord fabric wound on 63-66 inch long core tubes, the rod 11 is preferably abbout 30 inches long and the sleeve 12 about 6 inches long.
- a metal disc 13 is welded to the rod at one end thereof, the disc being of somewhat greater diameter than the rod to define a periplieral flange about the latter.
- An annular metal disc or washer 14 is welded concentrically to the end of the sleeve 12 facing away from the flanged rod end and defines an outwardly directed peripheral flange on the sleeve.
- the diameter of the disc 13 exceeds that of the rod 11, preferably by an amount approximately equal to the wall thickness of the sleeve 12, and the outer diameter of the annular disc 14 is somewhat greater than the inner diameter of the roll core tube with which the rod/sleeve combination is to be used.
- a set screw 15 is carried by the sleeve 12 with its tip 15a extending through an opening in the sleeve, so that by tightening the screw against the rod 11, the rod and sleeve can be locked to one another in any selected relative adjusted positions.
- the rod 11 is further provided with a small radial protuberance 16, for example a spot weld, to prevent separation of the sleeve from the rod when the set screw 15 has been loosened to permit relative movement between the rod and the sleeve.
- a small radial protuberance 16 for example a spot weld
- FIGS. 3, 4 and 5 The manner of use of the lifting/ bracing rod structure 10 of the present invention in the handling of a roll 17 of tire cord fabric 18 wound on a tubular roll core 19 and wrapped in a polyethylene liner 20 and a paper board outer cover 21 fastened by metal straps 22, is illustrated in FIGS. 3, 4 and 5.
- the unflanged end regions of the rods 11 of two rod/sleeve combinations 10 are inserted into the respective opposite ends of the roll core tube 19 (FIGS. 3 and 4) until the flanges 14 of the sleeves 12 abut against the ends of the roll core.
- the sleeves be locked to the rods with the unflanged ends of the sleeves 12 in abutting relation to the respective flanges 13 of the rods 11, so as to maximize the stability of the system.
- the sleeve-covered portions of the structures 10 can then be engaged from below by a pair of hook arms or cradles 23 (FIG. 6) of a suitable adaptor 24 or similar adjunct of a conventional fork lift truck without any need for the regular forks of the latter to engage any part of the roll or the outer protective covering thereof. It will be apparent that this advantage will exist even, and especially, when the roll 17 is a part of a multi-tier stack of such rolls.
- the rolled up material need not be the cord fabric but may be any other type of woven, knit or non-woven fabric, any type of sheet material other than fabrics, yarns and other filamentary strands, etc.”
- the flange on the rod may be defined by an annular disc, ring or washer welded thereto or even by an upset portion of the rod and may even further be of less than full circumferential extend, say analogous to the protuberance formed on the other end of the rod, and other types of interlocking means than a set screw may be used to lock the rod and sleeve to one another in their adjusted relative positions.
- Other variants of these and other aspects of the invention will readily suggest themselves to those skilled in the art.
