Definitions

  • K. P. BILLNER HANDLING APPARATUS Filed Sept 8, 1944 2 Sheets-Sheet 1 July 5, 1949.
  • This; invention relates. to handling, apparatusfor usein reinforcing. and lifting bodies.- ofvari-- ous types.
  • ViZhereas this invention is applicable toa-large number of'uses, it is of particular valuein the handling; ofbodies of extensive surface areaand relatively low. resistance to bending stresses Sheet glass and'prefabricated concrete walls are clearly'in this category, audit will be of interest to point outthat'prefabricated' concrete walls of only two and one-half inch thickness, containing sash and door openings, have been successfully handled in accordance with the principles of this invention. Use in raising sunken vessels is also contemplated, and according to one of its aspects, the apparatus is admirably suited for temporarily reinforcing materials being handled.
  • Mats have been constructed for suspension from a hoist, a mat comprising a hollow body having an open side for application to the surface of the body to be lifted, there being gasket means carried by the mat for effecting a seal with respect to such surface.
  • the interior of the mat is adapted for connection with a source of sub-ambient pressure. In the case of atmospheric conditions, sub-ambient pressure would be sub-atmospheric. while in cases of submarine operations, sub-ambient pressures might exceed atmospheric.
  • the mat may be provided with yieldable supports or spacers at points intermediate the sealing gasket.
  • Reinforcing means in the form of a rib or stiffener may be provided for one or more surfaces of the mat for attachment to the hoist.
  • a plurality of mats, contiguous or spaced may be joined to a single backing or reinforcing element, such structures adapting themselves as temporary reinforcing beams for structures undergoing stresses.
  • Undesired transverse movement of the seal- Some of the principles of these practices 2 ing gaskets may. be prevented by embedding them in grooves or between. heads provided by the mat; In. some cases the means for producing.
  • sub-ambient pressures may be mounted. on or closely adjacentthe mat, and valvemeansmay be similarly. positioned. to afford convenient control a-t. themat- A more complete understanding; oi: the inven-- tion will follow from. a description. ofi the attaclried drawings wherein;
  • Fig. 1'. is. a. somewhat diagrammatic perspective" showing. the. use of a. hoist for handling a rein-- forced. concrete wall. and temporary reinforce-- ment at an opening in the wall;
  • Fig.. 2 is. a. bottom. plan view of.- amat. of the type depicted. in. Fig. 1.;
  • Fig. 3 is sectional. elevation. of themat of. Fig.
  • Fig. 4 is a. bottom plan ofa modified. form of main"
  • Fig. 5 is a sectional elevation of the mat of Fig. 4;
  • Fig. 6 is a bottom plan of another form of mat.
  • Fig. '7 is a sectional elevation of the mat of Fig. 6.
  • the prefabricated concrete wall 20 of Fig. 1 includes a door opening 22 and a window opening 24.
  • the wall is depicted in a vertical position to which it has been elevated by a hoist whose hook 26 is connected through cables 28 to a spreader 30 which is in turn connected by cables 32 to the mat 34.
  • the mat comprises a frame 36, composed of plywood, sheet metal or other suitable material, the rear surface of which is reinforced by a rib or web 38 by which it is attached to a hoist by means of rings or perforations (not shown) suitably provided therefor.
  • the front face of the mat is provided with beads 4
  • A'nipple 44 containing a valve 46 provides means for connecting the interior of the mat with a source of sub-ambient pressure.
  • the reinforcing beam 48 bridging the door opening 22 of Fig. 1 is provided with a mat 50 at either end, similar to the mat 34 of Fig. 2.
  • the mats 50 will establish a firm hold upon the wall surfaces and permit the beam 48 to strengthen the structure during handling.
  • the mat 54 of Figs. 4 and 5 is somewhat similar to that of Fig. 2, having a gasket 42 held between beads 40, a pair of reinforcing ribs 38 provided with rings 56 and a valved nipple 44. Since the mat of Fig. 4 covers a larger area, than that of Fig. 2, intermediate supports 58 have been provided in the form of flexible elements such as rubber to prevent collapse of the mat when it is subjected to differential pressures. These intermediate supports are shown as being of a button type, retained in position by beads 60 formed on the front face of the frame.
  • a mat 62 is depicted in Figs. 6 and 7, especially adapted for submarine use.
  • a frame 36 receives a marginal flexible gasket 42 retained by beads 40, thus presenting a hollow body having an open side for application to the surface of a body to be handled.
  • a suitable driven pump 10 is also carried on the rear surface of the mat for producing a sub-ambient pressure between the front surface of the mat and the surface of a body to be lifted or otherwise handled.
  • the pump is connected with the interior of the mat by a tube 12, and may deliver through a tube 14.
  • the sealing gasket in each case will be of sufficiently flexible material such as rubber, to permit the mat to adapt itself to irregularities of surfaces sufficiently to maintain the necessary pressure differential for operation of the present principles and apparatus.
  • a structure comprising a body having a discontinuous surface, a reinforcing implement temporarily bridging the discontinuity during handling of said body, said implement comprising a beam rigidly supporting a plurality of spaced vacuum mats for engagement with said surface at opposite sides of said discontinuity, means carried by said mats to effect sealing relationship with said surface, and means connecting said mats with a source of sub-ambient pressure.
  • a structure comprising a substantially rigid body weakened by an opening, a reinforcing beam bridging said opening, said beam rigidly supporting a pair of spaced open vacuum mats for engagement with said body at opposite sides of said opening, a readily deformable sealing gasket secured at the open portion of each of said mats for engagement with said body, and conduit means for connecting the interior of each of said mats with a source of sub-ambient pressure.
