Application filed July 5. 1912. Serial No. 3.
To all whom it may concern lie it-kl'iownthat I, THEODORE L. RICH- Monn, a citizen of the United Ststes residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvement in Suspension-- Bearings for Platform-Scales, oi which the following is a specification,
.'lhis invention relates more particularly to platform scales, such as wagon or railway scales, which are employed for weighing heavy objects. Scales of this kind have generullybeen so constructed that the parts of the platfornr knife-edge hearings were rigidly secured to the platform levers and the platform. Owing to the tendency of the pliitforin to shift horizontally more or less when the load is moved onto and oil of the same, causing the knife edges to grind against the bearings, it was foundv desirable in certain cases to suspend the platform from the knife edges in such a manner as to permit the slime to swing to a certain extent without transmitting the motion of the platform to the platform levers and knife edges. This was accomplished by suspendingihe platform from the platform levers by two links depending from each knife edge bearing at opposite sides of the platform lever. This construction necessitated the use of a suitable equalizing device for distributing the pressure diie to the load on the platform equally between the two links, and consequently causing an equal distribution of pressure on the platform knife edge.
The object of this invention is to produce a suspension bearing for platform scales in which only one link is employed which distributes the pressure evenly throm hout the leuo'th of the knife edge, whereby the usual equalizing means can be dispensed with and the construction of scales of this kind accordingly simplified. I
In the accompanying dmwings: l igure l. is u fragmentary transverse sectional clevution of 1' platform scale embodying the invention. Fig; 2 is a broken plan view of one of the platform levers and associated bearings. 3 is a transverse sectional e 15),. elevation thereof on line 3'-3, Fig. 2.
Like reference characters refer to like parts in e several figures.
Flhe suspension hearings are illustrated in the drawings in connection with the usua system 0 lati'orzn supportinglevers con: sisting transverse levers fulcr uned ad picent to opposite sides the platform .1 suitably connected to longitudinal lev which are fulcruniecl adjacent to open, ends of the platform. and one of which connected to the scale beam.
. it represents two of the transverse p lorni levers, and a one of the loneitudi levers to which the transverse levers I connected by suitable knife edge pivots m. L ach of the platform levers has lhe usual fulcrum knife'edge a" which hears on a suitable fixed stand a mounted-Gen foundation or nbutinents of the of these parts of the so: lecreek limiter specified. may be ofthe usual or suitable construction.
Each of the supportinghesins or ,q irders E1 of the scale platform rests on bifurczil rl supports or arches B secured their nmer iuls to the beam. Each of these or: straddles one of the platform levers he depending leis Z) of the arch extendinp L 1 7 1 v 1 row ihe lower edge of the Lever and QC-MW connected at their lower extremities bv pin or cross bur b which rests in a loop or linl: (l suspended from the platform le A. The cross bar or .pin is PIQfQTZ-lll'm rcniovubly secured in the arch B so as I fucilitnte the dismantling of the scale preferably has a groove 5 in which th loop or link rests.
. in order to distribute the st 35885 plutfm'ni luzltl evenly over the pie hearing: of the plutforn'i lever A 15v: 1! of the single link C, the following slruci'ion is employed: The lever is \'l(ll".(l with :1 vertical slot D them the link (7 extends, The pletfr i. edger i is located ut the upper edge 0; lever mid bridges the slot l), the sins portion of the lever heins prefers widmed to slrengthen the lever ind an extended support for the knife edge. hearing block F with 1 hardened piece f bea s on the knife edgr link C passes ever end beurs nt end on the bearing block, prefers groove f therein. The lever s pro provided at opposite sides w on u extending fingers or parts 7 which p lhe'displzueinent oil the beuring lilo-cl the knife edge The link is ad swing on the bearing oloel: l? I wise and crosswise so that in the use I f e of the lever and bridgin said slot, a
both longitudinally and transversely there of without causing any grinding of the knife edge E on the bearing block F.
By means'of the construction described it is made possible to employ only one link in the suspension bearing, and no equalizingineans are'necessary, since the load is centrally "applied and evenly distributed throughout the platform knife edge, thereby simplifying the construction and reducing the COStoOf scales of this kind.
, I claimas my invention:
1. In a platform scale, the combination of a platform lever having a vertical slot extending through the same, a platform knife edge resting on the upper face of the lever and bridging the slot, a bearing for said knife edge, a link extending through said slot and passing over and supported on said bearing, and means for sup orting the platform from the lower-part 0 said link.
2. In a platform scale, the combination of a platform lever having an enlarged portion and a vertical slot extendin through said enlarged portion, a platform Irnife edge resting on theupper face of the enlarged ort ion ea ring for said knife edge, a lin extending through said slot and passing over and supported on said bearing, and means for supporting the platform from the lower part of said link.
3. In a platform scale, the combination of a latform lever having a vertical slot extending through the same, the portions of saidlever forming the side walls of the slot being of increased thickness at the upper face of the lever, a platform knifeedge resting on the upper face of the lever and bridging the slot, abearing for said knife edge, a link extending through said slot and passing over and supported on said beara link extending through said slot and passing over and supported on said bearing, and means for supporting the platform from the lower part of said link.
5. In a platform scale, the combination of l a platform lever having a vertical hole extending through the same, a platform knife edge supported on the upper face of said lever adjacent to said hole and which is of greater length than the width of said hole, a bearing for said knife edge which bears substantially throughout the length of said knife edge, a link which is suspended from said bearing and which extends through said hole in the lever, a bifurcated support for the scale platform having downwardly extending legs and which straddles said platform lever, a pin connecting the lower extremities of said legs and resting on the lower end of said link, and means for preventing the pin from sliding relatively to said link.
Witness my hand, this 3rd day of July, 1912.
