DAVID MARSH, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO T. B. STOUT, J. A. CODY,

AND DAVID MARSH.

HANGING MILLSTONES.

Specification of Letters Patent No. 14,128, dated January 15, 1856.

To all whom it may concern:

Be it known that I, DAVID MARSH, of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hanging Stones for Mills upon the Spindles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, of which Figure 1, is an elevation; Fig. 2, a plan or top view of the balance rynd; Fig. 8 a cross section exhibiting the slot or recess in which the feather drops; Fig. 4, a view of the lower end of the spindle and section of the cup and step.

The nature of the improvement consists in securing the carrier or balance rynd to the spindle by means of a vibrating feather inserted in the spindle, said feather admitting of being dropped in a slot and under a recess of the balance rynd, so as to allow of the introduction of keys to secure the rynd to the spindle for the purpose of admit-ting of a ready removal of the spindle from the stone when necessary.

To enable others skilled in the art to construct and use my improvements I will proceed to describe them as follows:

A A are uprights of a frame; B B, the upper and lower cross timbers; C, a bridge tree for raising or lowering the step 011 which the spindle rests; D, an iron spindle and E a feather inserted loosely in a slot in the spindle; this feather is pivoted on a pin a (Fig. at) upon which it has a slight vibration.

F is the balance rynd or carrier. Its arms I) 6 project from opposite sides thereof and it is upon these the runner stone is suspended.

G represents the stone see Fig. 3.

(Z is a vertical slot in F, into which the feather E is dropped sufliciently low to allow of the spindle being slightly turned and the feather thrown into the recess 6; by this means a projection, f, is formed upon which the stone is suspended; g, g, are keys fitting in the slots (Z,'(Z, and by which the feather is retained in the recess 6.

The lower part of the spindle is made smaller than the cup H, to allow space for retaining oil in the cup; the cup is inserted in an open ring I, being connected (see Fig. 5) therewith by arms h h and by this means allows of all dirt or filth from the oil to pass away from the step, and the joint prevents the admission of dirt or dust, &c.

The improvement in sheltering the lower step or cup, from dirt or filth falling in and remaining is important; the holes at the sides of the step allow its passing from the cup. The ring and cup or step readily admit of removal for the purpose of oiling, without disturbing the mill or runner stone, simply by dropping the bridge tree and with itthe ring step.

Having described my improvement what I claim as my invention and desire to secure by Letters Patent is The mode of securing the carrier to the spindle by means of the vibrating feather inserted in the spindle it admitting of being secured by keying in a recess in the cap sub stantially as set forth.

DAVID MARSH.
