Abstract
Abstract of the Disclosure An improved weighing apparatus includes a load receiving platform which is supported by a plurality of load cells. Each of the load cells has a downwardly facing recess in which a floating pin is received. The pin has a relatively large base which engages a floor or support surface and an upwardly projecting mounting section which extends into the recess in the load cell. The pin has an arcuate upper surface which enables tilting movement to occur between the pin and the load cell to compensate for uneven floors, In order to compensate for shifting movement of the plateform relative to the floor due to thermal expansion and other causes, the base of the floating pin is movable along the floor. The mounting section of the pin is held in the recess in the load cell by a retainer plate which is fixedly connected with the load cell.

Descri~tlon of One Specific Preerred Embodiment of the Invention .' The installation of a load platorm 12 in a frame 14 of a weighing apparat~s 10 constructed in accordance with the present invention is illustrated in Fig. 1. The rectangular frame 14 is disposed in a shallow pit 16 fvrmea in a concrete floor 18. When the load platorm 12 i~
received in the frame 14, a flat upper surface 20 is aligned with an upper sarface 2Z of the floor 18.
A load ce.ll is provided at each of the four corners of the rectangular plat~orm 12. Thus, a load cell 24 is disposed in corner 26, load cell 28 is disposed at a corner 30, a load cell 32 is disposed at a corner 34, and a load ,;

In accordance with a feature of the present invent;on, each oE the identical load cells is provided with a downward].~ projecting floating pin or force transmitting member ao. The identical pins 40 engag~ a flat bottom or support surface 42 of the p.it 16 to support the platform 12 with its -load surface 20 in a common plalle w:ith the surface-22 of the floor 18~ Of course, once the load plat~orm 1~
has been installed in the frame 14, the chains 46 and screw eyes 48 are disconnected from the load platfor~ to provide a flat upper surface onto which a vehicle can be easily driven.
During the installation of ~he load platform 1~, the floating pins or ~rce transmitting members 40 are retained in recesses forme.d in the ~oad cells. Th-ls, the load cell 24 (see Fig. 2) has a rectangular body 52 with a downwardly facing recess 54 adjacent to an outer end of the body 52.
During installation of the load platform 12, the floatin~
pin 40 is retained in the downwardly facing reaess 54 by a retainer plate or member 58.
When the load plat~orm 12 is installed in the frame 14 ~Fig. 3) a circular bottom surface 64 on a base 66 of the floating pin 40 abuttingly engages the bottom surface ~2 of the pit 16. The bottorn surEace 64 oE the base 66 is ;

( slidable a~ong the concrete support surface 42 to accomrnodate shifting movement of the load cell 24 in a direct;on parallel to the sup~ort surface ~2 due to thermal expansion and other causes. It should be noted that if the pin 40 was fixedly connected with the f~ame 14, the bottom surface 64 of the pin 40 could not move along the concrete floor or support sureace 42 to accommodate shifting movement of the load cell 2~ relative to the ~loor.
A mounting section 70 (Fig. 3) of the floating pin 40 extends upwardly from the base 66 into the downwardLy facin~ recess 54 formed in the load cell 24. The mount;ng section 70 includes a cylindrical neck or connector section 72 whic~ is connected with a conically taperecl section 7 of ~he base~ ~he conically tapered section 74 of the base is connected with a c~lindrical pad or hottom section 76 oE
the base 66. The pad or bottom section 7~ of the base 66 has a diameter which is substantially greater than the diameter of the connector section 72 to distribute the force transmitted between,the load cell 24 and the concrete floor 42 of the pit 16 over a relatively ~axge area.
In addition to the connector section 72, the mounting section 70 has a head ena portion 80 which is disposea be~ween a flat inner side surface 82 (F;g. 3) of the retainer plate 58 and a flat circular bottom surface B4 oE

There~ore, during installation of the ~oad pl~t~orm 12 (see ~i~. 11 the float;ng pins 40 are held in the downwarclly facing recess ~4 in the associated load cells by re~ainer plates 58. Since the pins are held in the downwardly facing load cell recesses, it is not necessary to align the pins with the recesses as the platform is installed.
- ~he head end section ~0 of the floating pin 40 has an upper sur~ace 92 (Fig. 3~ which engages the bottom surface 84 of the recess 54 to transmit a load between the floating pin 4~ and the load cell 24. Thus, when a vehicle is driven onto the load platform 12 ~Fi~, 1) the load is transmitted downwardly to the'four load cells at the corners 26, 30, 34 and 36 of the platform. The load is then transmitted from the cells to the floor 42 of the pit 16 through the downwardly pro~ecting pins or force transMitting members 40.
It is contemplated that the weighin~ apparatus 12 may be installed in pits 16 (see Fig. 1) havin~ bottom surfaces which are uneven. The uneveness of the ~ottom surface or 2S floor 42 of the pit may he intentional in order to provide . ' ''' .

In either case, tilting movement can occ~r between the downwar~ly extending p;.ns and the load cells to compensate for the uneveness in the floor 42~ Thus, the upper surface 5 92 of the f.loating pin 40 (see Fig. 3) has a configuration corresponding to the configuration of a portion of a sphere. The spherical surace 92 is disposed in abutking engagement with the ~lat circular bottom surface 84 of the reces5 54. The head end portion 80 has a cylindrical outer side surface ~6 which is spacea from a cylindrical $ide surface ~8 of the recess 54 to acco~nodate sidewise ~ilting movement between the floating p;n 40 and the load cel:L 24 Of coursey this limited sidewise tilting movement of ~he pIn 40 relative to the load cell ~4 is facilitated by the spherical confi.guration of the upper surface 92 o~ ~he pin 4~.
The connector section 72 extends through a generally U-~haped slot 102 (see Fig. 4) formed in the retainer plate 58. It should be noted that the slot lO~is define~ by a pair of longitudinally extending side or leg surfaces 104 and 106, which are interconnected by an arcuate bight surface 108. The semi-circular 5urface 108 has a diameter which is slightly greater than the diameter o~ the .
cylindr.ical connector section 72.
The annular bottom surface 88 of the head end portion 80 o' the pin 40 hrs an outside diame~er which is g~cater .. .

The head end portion 80 of the floating!pin 40 flairs out~ardl~ (see Fig. 3) to the annu~ar bottom surface 88 to thereby tend to maximize the radial extent of th~e bottom sur~ace. Thus, the annular downwardly facing end surface 88 of the head end portion ~0 is connected with the cylindrical side surface 96 by a conical upwardly sloping side surface 114 (Fig. 3). The recess 54 is providecl with a similar con;cal upwardly sloping side surface 116 which extends generally parallel to the sur~ace 114 to receive the outwardl~ flaring lower portion of the head end section 80.
In view of the foregoing description it is apparen~
that the present invention relates to a new and improved ~eighing apparatus 10 having a platform 12 with a plurality of load cells 24t 28, 32. Each of the load cells has a downwaraly facing opening 54 in which a floating pin or ~orce transmitting member 40 is received. The fLoating pin 40 has a re]atively large ~ase or pressure pad 66 which directl~ engages a support surEace 42 and is slidable along the support surface to accommodate shifting movement o~ the platEorm l2 relative to the support surface.

the f.loating pin 40 has an arcuate uppe~ sur~ace 92 which abuttingl~ engages the bottom 8~ of the recess 54 in-the load cell to accommodate tilting movement between the load cell an~ the pin.

invention, a retainer mem'~er 5~ is provided to hold a mounting section 70 of the floating pin 40 in the downwardly facing recess 54 in the load cell when the base 66 o~ the pin is spaced from a support surface ~Fig.. 23.
