KEL-LOGG H. L'OVOMIYS, OF NEW YORK, N. Y.

Letters Patent .Nm 82,728,- dated October 6, 1868.

IMPROVED ANTI-EMOTION 'STEAM-ENGINE VALVE.

@its tlitbule referrer In in tigen Enters tant animating putt nf tige tame'.

TO ALL` WHOM IT MAY GONCERN:

Be it known that I, KELLOGG H. LooMIs, of the city of New York, in the county of lNew York, and State of' New York, have invented a new and useful Improvement; in Anti-Friction Valves for Steam-Engines; and I do hereby dec-lare that the following is a full, clear, and exact description thereoi',v reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure l is a .vertical sectionof the steam-chest, valve, and valve-seat.

Figure v2 is a side view of the oscillating-yoke by which the valve is operated.

v Figure 3 is a plan view of the valve-seat, and

Figure 4 is a plan view of the valve detached from its seat. y

A is the steam-chest, and a the induction-port; B, the valve, conical inform, and C the valve-seat, of corresponding form. i

The valve has a series of steam-ports, b, extending through it, vertically or parallel to its axis, and the seat has a corresponding series of similar ports, c. Said ports are alternately opened and closed .by partially rotating the valve, Vor giving ita circularly-reciprocating motion. v i

The solid spaces between the ports of the valve taper upwards, or towards the base of' the inverted cone,

terminating in ribs, b', Hush with sa'id base, thus forming solid masses of metal between the ports, extending from the base to the outer surface and apexl of the cone, and giving the ports an upward flare; and 'said deep ribs efectually prevent the valve from springing or yielding to thepressnre of the steam.

B'L is the valve-stem, passing through and having a bearing in the steam-'chest cover D,'and also passing through a stuiing-box, d. Said valve has its upper bearing or journal in a cross-support, E, at e.

F is a circular yoke,embracing the cross-support E, and having a projecting lever-arm, F', by means of which it is oseillated to operate thefvalve.' The valve-stem passes throughand is rigidly secured to the lower portion ofthe yoke, atf.' v n H is a set-screw, passing vertically through the upperportion ofthe yoke, at t,.in line with the valvessteni,

.and its lower conical end rests or has its bearing in a. socket, at h', `in the upper side of the cross-support E,

z 'is a jam-nut, on the set-screw above the yoke Rand j is a nut, and j axiam-nut, on the valve-stem, between the lower portion ofthe yoke and thersaid cross-support.

It will be seen that the valve has its bearing and turns upon the centre, t, at the lower end of the setscrew, and is adjustable vertically by means of said set-screw, as by turning the set-screw, so as to force it downward, the --valve will be raised from its seat; consequently the steam-pressure on the top of the valve cause;x no increase of friction between thevvulve and its seat; andas thevalve turns upon a centre point in the line ofits axis, the friction will be inconsiderable, however great the pressure on the valve.

What I claim asmy invention, and desire tosecure by Letters Patent, is-

1. An oscillating steamvalve, suspended from and having its bearing and "turning upon an adjustable centre-point above its seat, in the line ofits axis, substantially as described.

2. In combination, the valve-stem, support E, yoke F, and set-screw H, all constructed andarranged substantially as shown and described. i

3. 'The arrangement of the ribs b between the ports, extending from the base to the; outer surface and apex of th cone, substantially as set forth.

KELLOGG H. LOOMI-S'.
