ELIII-IALET DOUGHERTY, OF N ORTII LEWISBURG, OIIIO, ASSIGNOR TO IIIM- SELF AND J. lll/FLOOD, OF SAME PLAGE.

L cttcrs Patent No. 101,109, date-cl llIarch 22, 1870.

IMPROVEMENT N STEP-SPINDLES.

The Schedule referred to n these Letters Patent and making part of the same.

To all whom it may concern Beit known that I, ELI'rnALnT Douennn'rv, of North Lewisburg, in the county of Ohampai gn and in the State of Ohio, have invented certain new and useful Improvements in Step-spindles; and do hereby declare that the following is a full, clcar,'and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

rI`he nature of my invention consists in the construction and arrangement of a step-joint with ratchet and bearing, so as to place a run of stone directly over a perpemlicular sha-ft, in order that none of the weight ofthe stone spindle or driver bears on the water-wheel shalt, or so as to place one joint of heavy Shaft-ing perpendicular. above another, and each separate joint bears its own weight, and by the ratchet all damage from the sudden stoppage of the drivingwheel is prevented, for the reason that the machinery is allowed to run on by its own momentum, without inthe slightest injuring the machinery by the shock.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a vertical section, and

Iligure 2, a horizontal section of my invention.

A represents a circular plate, with tube extending downward, and is iirmly secured in the bridge-tree.

\Vitllin thistube is placed another' tube and plate,

B, provided with an inner rim, a, and an outer rim,.

l), extending above its face, forming a suitable receptacle for the lubricating substance.

Around the inner rim a is placed a fiat ring, d, upon which the hollow step-spindle is to move.

At or near the outer edge on the upper side of this ring d is placed another steel ring, c, which surrounds the spindle and keeps it 1n place while running.

Screws f j' rass through the outer rim l) and bear against the ring @which serves to tram the spindle to the face of the stone, or to line the shafting, if the step-spindle is used on such.

. The outer rim b isprovided with two ears or pivots,

g g, which rest upon the lever C, so that the entire plate and tube B can be raised or lowered while the stone is grinding, or to adjust the shaftinr.

D is the step-spindle, which is hollow, and provided with slots h l1., in which the driver works.

rlhe foot of the step D is formed by shrinking a steel band around the main casting, as shown in figl.

The driving-shalt E passes up through the tube B,

and is near its upper end 'ln'ovided with thelowerhalt' viof a ratchet, the upper half of which is formed by the driver (l, placed upon the shaft and iitting within the slots hy h ot' the step I).

A spring, on, at the upper end of the shaft ll holds the driver G close to the ratchet i.

It will readily be seen that when the machinery is in operation, the water-wheel may be stopped by driftwood or from any other cause suddenly, and still the machinery is allowed to run on by its own momentum, without becoming injured from the. sudden shock. i

Having thus fully described my invention,

That I claim as new, and desireto secure by Letters Patent, is

1. The hollow spindle-foot D, provided with a steel ring shrunk around its lower end, substantially as and for the purposes hereinv set forth..

2..lhe driver' G, ratchet Ii, and spring m, working inside of the hollow step I), substantially as and for the purposes herein set i'orth.

3. The combina-tion ofthe hollow step I) and rings d and e, substantially as and for the purposes herein s et forth.

4. rlhe plate and tube B, provided with rims a and 1J and ears or pivots g g, all substantially as and for lthe purposes herein set forth.

o. lhe combiuatiouof the plat-es and tubes A B, lever C, hollow stop I), rings d c, shaft Ill, driver G, ratcheti, and spring nl, all constructed as described, and arranged to operate substantially in the manner and for the purposes herein set forth.

In testimony that I claim .the foregoing, I have hereunto set my hand this 6th day of December, 186i).
