.lfignre lll is a cross-section of the beam, showing the pivot-pin and stop as arranged therein.
Lilie letters of relerenee designate like paris in each ofthe Iignres.
A is the main heam ol' :my ordinary weighingscale;
B is the pivot-pin 5 (l, the supporting-yoke: and
l), my improved key, arrangedin a key-seat, e, in
the heam nndernealh and separate from the pivot-V hole.
lhe endl of this key are provided with arms d (Z, whieh project upward in Contact with the. edge of' the. pivot.
llne arms, at the point of Contact, are preferably formed with a notch, to receive the edge ofthe pivot, which renders the Connection between them more seenre.
The ends of the key are beveled, as heretofore, so as to hear against the sides of the tvoke and secure lheheam againetlateral movement.
My improvement is more important iorseale-beams ol' large size, which require lone pivot-pins and wide yokes lo seeure lateral steadiness, for it enables -the cross-sectional dimensions o'f the key to be increased in proportion to its length, lie-side the other advantages before enumerated.
