S. J. AUSTIN. Platform-Scales.

FIGS-.1.
ATTEST:
UNITED STATES PATENT QFFIGE.
STEPHEN J. AUSTIN, OF LITGHFIELD, ILLINOIS.
IMPROVEM EN T IN PLATFORM-SCALES.
Specification forming part of Letters Patent No. 200,683, dated February 26, 1878; application filed June 21, 1877.
To all whom it may concern:
ing of the platform upon the lever-frames on which the platformis supported.
My improvement consists in an arm whose rear end is provided with a knife-edge for supporting the platform, said knifeedge being located between the bearing-bar and bearingblock.
In the drawings, Figure I is a perspective view of my improvement. Fig. 2 is a section, showing the bearing I in elevation.
A is the floor of the platform, resting on beams B B, which are supported at each corner upon link-blocks O O, hung on links D, the pin 0 passing through the block and the link. The two links D D are upon the arms of E E, T-formed bearing-block, or T, which has a saddle, F, extending at a right angle to the arms E E, so as to prevent the T from swaying in a direction sidewise to the arms E. The saddle F rests upon a knife-edge, Gr, fixed in an arm, H, extending from sleeve K, fixed to the bar I. The barI connects together two of the corner bearings, and has a long arm, L, ending in an adjustable bearing-staple, M, for the bottom of rod N, through which communication is made with the scale-beam. O is a knife-edge, which is fixed in the arm H at a point nearer the end of said arm than the knife-edge G, and this knife-edge O rests on the bearing-block P, supported on the foundation R, either directly, as shown in dotted lines, or through medium of rollers Q Q.
It will be observed that with the described manner of supporting the platform no horizontal movement will tend to move the knifeedge bearings, and thus they will be preserved from wear.
I claim as my invention- The bar L, having an arm, H, provided with a knife-edge, G, intermediate of the bearingbar I and bearing P, sleeve K, and knife-edge O, in combination with the platform A B, T- piece constructed with arms E E and saddle F, and the links D D, adapted to engage with pins 0 0 of blocks 0 0, all arranged in the manner specified, substantially as set forth.
