Description

UNITED STATES PATENT OFFICE.
CLOSSON M. LEFFINGWELL, OF WILLIAMSBURG, OHIO, ASSIGNOR TO EDWIN N. JACK, OE SAME PLAGE.
IMPROVEMENT IN WAGON-BRAKES.
Specification forming part of Letters Patent No. 156,428, dated November 3,1874; application filed August 31, 1874.
State of Ohio, have invented an Improvementin Wagon-Brakes, of which the following is a specilication:
This invention is an improvement on the invention of Edwin N. Jack, patented November 25,1873; and consists in a ring,` secured to the brake-shaft outside of the places of attachment of the supportingrods to prevent any lateral motion of the same.
In the drawings similar letters of reference indicate corresponding parts.
A isthe brakeshaft; B, the ring; C, end of brace-rod at its place of attachment to the brake-shaft; D, rod for suspending the brakeshat't under the bed; E, a screw for securing the ring to itsl seat; H, nib-block. The relation of the` ringB to the rods C and D is such that all lateral motionvWhich Would have a tendency to disarrange the parts can be taken up, and at the same time support them in a direction which formerly has been left unguarded, thus contributing an essential benet to the Whole mechanism, With but a triing increase in cost. The ring B, in several dit'- ferent forms of brakes, instead of being attached to the brake-shaft by means of a screw, is shrunk on, and is driven up to the rods from time to time as they become loose by Wear.
I do not claim the ring or collarB in a general Way, as that is old; nor do I claim any particular form of attachment; but, as an essential improvement on the patented invention hereinbefore referred to,
I claim- The movable ring B, secured to the brakeshaft A outside of the places of attachment of the rods C and D, combined to operate as and for the purpose described.
OLOSSON M. LEFFINGWELL.
