To all whom it may concern:

Be it known that I, CHARLnsW. WEIGHT MAN, a citizen of the Unitedv States of America, and resident of Carlisle, in the county of vCumberland and State of Pennsylvania, having invented certain-- new and useful Improvements in Manure Spreaders,

of which the following is .a specification.

This inventionrelatesto manure spread ers, and particularly to an attachment adapted to be applied to a spreader which will prove effective to maintain the driving chain of such mechanism in operative engagement with the driving wheel which, in these devices, is usually in the nature, of

a sprocket wheel, novel means being also provided for disengaging the chain from the driving wheel when that is desirable or necessary.

It is a further object of this invention to produce a mountingfor one of the sprocket wheels of the driving chain well below the plane of the top of the periphery of the driving wheel, in'order that a greater num ber of links of the driving chainwill bein enga ement with the teeth of the driving whee a condition which traveling over "rough surfaces.

It is a still further object of this invention to provide an arm which is oscillatably the said arm having an angularly disposed or curved portion'which extends downwardly, in order that a spring action will result at the angularly disposed or curved portion. The

chainhas become stretched, so that by this invention the usefulness of the parts is pro drawings forming part 1 of this application wherein like characters denote-corresponde ried. It has been I prevents jumping of the chain, even though-the spreader-is driving chain,

flto theldrive wheel 5, in mounting also maintains the parts in operativerelation and in effective Working conditlon, even though the driving.

of comparatively inexpensive production; in that it. can be increase the efliciency and furthermore, the arm is formed wholly-by the stamping process. Iclaim:

In a drive mechanism for manurespreaders, a drive Wheel, a drive chain adapted to engage the periphery'of the drive Wheel for operating the distributor or spreader, an

arm osoillatively mounted above the drive Wheel, means connected to the arm on one side of the pivot for oscillating the arm, the said arm having a depending portion and an extension on the other side of the pivot,

action With rel a Wheel rotatably ation to the drive wheel, and mounted on the extension of the arm engaged by the drive chain and adapted to move the drive chain toward and away from the drive Wheel as the said arm is oscillated CHARLES WILLIAM WElGl-ITMAN.
