$PECIEICATION forming part of Letters Patent No. 341,424, dated May 4, 1886.

Application filed March 6, 1886. Serial No. 194,215. (No model.)

To rtZZ whom it may concern.-

Be it known that I, EDMUND LUNKENHEI- MER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Straightay Valves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this I specification.

Hy invention relates to that class of strai ghtway valves designed more particularly for throttle valves, and known generally as quick-opening valves. lthas forits'object r 5 thegeneral improvement of this class of valves, by which both cheapness of construction, compactness, and efficiency of action are obtained.

The novelty of my invention will be herein set forth, and distinctly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improved valve. Fig. 2 is a side elevation of the same with the cap removed. Fig. 3 is a sectional side elevation through the line .r 50 of Fig. 1. Fig. atisasectional side elevation of the shell through the line y y of Fig. 1.

The same reference-letters are used to indicate identical parts in all the figures.

The shell or casing A of my valve, although integral, may be said to be composed of an enlarged central chamber, a, the two internally threaded straight-way connections I), on each side of and opening into the central chamber, the projecting side nozzle, 0, opening into the central chamber, and provided with a removable screw-cap, d, and the tubular portion (2, arranged to the side of the central chamber, and the upper portion, b, as seen more particularly in Figs. 2 and 3. I

Extending diametrically across the valveseat fis a rib, intended as a support and guide for the valve 13 in its vibrations when being opened or closed, thereby preventing its tilting and the wear that would be occasioned without this guide. This valve B may be of the usual or any ordinary construction, with an upper ground rim to fit snugly to the seat j", and an under central spindle, h, confined in a socket, i, in the vibrating carrier 0. This carricrC is adapted to swing horizontally in the chamber a, and is secured at its rear end upon the shank of a shaft or spindle, D,journaled in the tubular portion e of the shell A.

It has a boss upon its under side, just under the socket i, in which is screwed a follower, j, which, entering the socket, bears against the under side of the spindle h, and serves to adjust the valve and take up or compensate for the wear occasioned either by use or. from the necessity of regrinding. The outer end of the carrier is provided with a downward beveled shoulder, k, which, when the carrier is swung around to close the valve, rides up upon a beveled or inclined projection,E, extending from the side of the chamber a in such manner that the valve is raised and forced evenly and positively against its seat, as will be readily understood.

To prevent injury to the edge of the valve when it is thrown open, I provide a stopshoulder, Z, upon the carrier, which comes in contact with the wall of the chamber a, and prevents the valve, when wide open, from striking the cap (I.

The shaft or spindle D is stepped in a socket, m, and is held down from displacement by a stuffing-box, F, and a collar, 12, upon said shaft, and between which collar and stuffingbox the packing is contained. The upper end So of the shaft is provided with a handle, G, or any suitable means for oscillating the same, to cause the vibration of the carrier 0, and the consequent opening or closing of the valve.

It results from the above construction that by merely taking out the stuffingbox and drawing out the shaft D, the carrier C and valveB may be removed through the nozzle 0, for any purposes of inspection or repair, and this with out loosening any connections. It also results 0 from this construction that a perfectly-tight and positively-acting valve is produced.

While I have shown as my preferable con struction but a single valve and valve-seat, it is evident that a double valve might be employed to fit seats on both the upper and lower sides of the chamber a, and both of which would be carried and operated by the carrier O.

Having thus fully described my invention, I

claim- 1. The combination, in a straight-way valve,

of p the oscillating operatingshaft, the vibratiug carrier secured thereto, the valve adj ustably pivoted in said carrier, the valve-seat, and a Wedge or beveled projection with which the carrier engages to cause the valve to be forced positively to its seat.

2. In a straight-way valve, the valve-shell A, having the central chamber, a, and removable cap (I, in combination with an oscillating shaft, D, carrier 0, valve B, pivoted upon said carrier, and Wedge projection E, whereby,

ating parts may be withdrawn from the shell, substantially as and for the purpose described.

In a straight-way valve, the combination, With a vibrating valve-carrier and the valve pivoted thereto, of an adjusting follower by means of which the valve can be adjusted with upon removing the cap (7, the operl semz i reference to its seat to compensate for wear, substantially as described.

4. In a straight-way valve, the combination,

with the shell or casing, of a vibrating carrier
