STRAIGHT- WAY VALVE.

SPECIFICATION forming part of Letters Patent No. 360,167, dated March 29, 1857.

Application filed January 3, 1887.

To all whom it may concern.-

Be it known that I, EDMUND LUNKEN-- HEIMER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Straight-Fay Valves, of which the following is a specification, rei erence being had therein to the accompanying drawings.

This invention relates to that class of straight-way valves seen in Reissued Letters Patent No. 10,769, granted to me September 28, 1886; and the first part of my present improve ments consists in providing the free end of the vibrating carrier with a pair of faeesor bearings, which are automatically wedged against suitable seats in the act of closing the valve, as hereinafter more fully described.

The second part of my improvements consists in converting these faces or bearings into separate and independent valves, which are usually loosely coupled to the opposite sides of the free end of the aforesaid vibrating car rier, as hereinafter more fully described.

The third part of my improvements comprises a novel combination of devices for clamping together the margins of the looselycoupled valves, and yet allowing them to have a limited but sufficient play to compensate for any irregularity in manufacture, or for ordinary wear and tear, as hereinafter more fully described.

The Fourth part of my improvements comprises a novel combination ofdevices that prevents the spindle or stem ofthe carrier shifting longitudinally within the shell or casing of the valve, as hereinafter more fully described.

The filth part of my improvements comprises a locking device wherewith thelever or handle of the stem or spindle is so coupled to. the shell or casing as to prevent accidental shifting of said handle after the valve has been set to any specific adjustment, as hereinafter more fully described.

In the annexed drawings, Figure 1 is a section of my straight-way valve taken in the plane of its stem or spindle, the valves proper being shown in their closed condition. Fig.

2 is a vertical section of said valves and their seats. Fig. 3 is an elevation of the vibrating carrier detached from the shell or casing. Figs. 4', 5, and 6 are vertical sections showing Serial No. 223,199. (No model.)

three different methods of applying looselycoupled valves to said carrier. Fig. Tisafront elevation of one of the valves seen in Fig. 6. Fig. 8 is an elevation of the carrier seen in Fig. 6.

A represents the main chamber of the shell or casing, and B B are pipe-connections communicating therewith, said connections being usually in line with each other and having female threads I) b. Projecting laterally from this chamber and at a right angle thereto is a nozzle or neck, 0, of which a portion is seen in Fig. 2. This neck may have a cap screwed to it, as seen in my patent previously alluded to; or said cap may be held in place by being bolted to a flange of said neck. D represents a tubular portion of the shell or casing, the axis of said tube being parallel with the central line of the pipe-connections B B. This tube is screw-threaded internally at d to permit the engagement of a cylinder, E, the upper portion of which is chambered out ate, to form a stuffing-box, the packing of which is gland, F. This gland is screwed or otherwise engaged with the cylinder E, whoseinner end bears against a collar, g, of the valve stem or spindle G, that passes i'reely through the bore of said gland, and has a handle or lever, H, wherewith it is operated. The inner end of stem G has a journal, 27, and between said journal and collar g a square, I, is situated, which square traverses the eye] of the vibrat ing carrier J, the special shape of the latter being more clearly seen in Fig. The free end of this carrier has two faces or bearings, K K, which bearings close against the inclined seats a a of the shell or casing, as seen in Fig. 2. These bearings areusually made of soft metal or other composition, and may be either cast with or rigidly attached to the carrier, or loosely coupled to the same. v\Vhen rigidly attached, said bearings are simply east in undercut recessesjj of the carrier, as seen in Fig. 1; but the loosely-coupled valves previously alluded to may be applied to said carrier in various ways. As seen in Fig. 4, the free end of the carrier is armed with a pair of convex bosses, L L, adapted to enter concave seats or hearings or m of the loosely-coupled valves M M, which valves are retained on said carrier by clamps or ties N N. Of these compressed by means of an ordinary adjustable ties the upper one, N, has a shank, a, that is securely fastened in the periphery of valve M, while the other shank, n, of said tie occupies a small transverse groove, 0, of the opposite valve, M; but this arrangement is exactly reversed with the lower clamp or tie, N, as its shank it occupies the transverse groove 0 of valve M, while theshank n is securely fastened to the other valve, M. These ties prevent any separation of the valves when the carrier is either placed within or removed from the shell or casing, and at the same time they allow a limited independent movement of each valve; but said ties do not allow the valves to turn around upon their bearings, this contingency being provided for by the construction seen in Fig. 5, where the valves P P have bosses p 1;, that enter semicircular seats R R of the carrier. This arrangement serves as a universal bearing for the valves, and allows each of them to turn and yield in any desired direction. Another modification is seen in Fig. 6, where the upper edge of the carrier has a pair of wings, S S, on its opposite sides, which wings are supplemented by similar devices, 8 8, projecting from the lower edge of said carrier. These wings fit loosely around a portion of theinner margins of a pair of valves, T T, which latter are grooved circumferentially at it, to receive the ties or clamps U U. The upper tie, U, is shown bent back on itself in the middle and then fastened in a suitable pocket in the carrier, while the lower tie, U, is represented as being attached to said carrier by a screw or rivet, it. (Seen in Fig. 8.) Furthermore, said carrier has a pair of convex bosses, VV', that enter the concave seats or bearings 12 o of the valves. This arrangement allows eachvalve to turn or adjust itself independently of the other valve, and the wings S S s s relieve the couplings V 12 V o of any strain when said valves are both opened and closed. The valvecasing is provided with a socket, D, to receive the shank w ofa standard, \V, having a lateral extension, X, provided with a bolt, Y, that passes through the slot h of the handle or lever H. Z is a thumb-nut for this bolt.

It isevident the operation of carrier J is the same as in my patent previously alluded tothat is to say, when the free end of this ,device is raised the bearings or valves K, K

pass up into the neck 0, and thereby allow a free and unobstructed passage through the shell; but when the free end of this carrier is swung down said bearings or valves wedge in between the inclined seats a a, as seen in Fig. 2, and thus effectually close the passage th rough the shell or casing. When thus closed, it is apparent the seat a serves as an abutment that forces the valve K against the other seat, a, and vice versa. After the valve has been opened as far as may be desired the thumbnut Z'is tightened, which act clamps the handle H immovably to the extension X, and thus prevents the spindle G being turned in either direction by the vibration of the engine or machinery. If steam, water, or other fluid should bear against the valve K when it is closed, the pressure thus imposed on the carrier could not force the stern G toward the gland F, because the collar g of said stem is at all times in close contact with the inner end of cylinder E, and the latter is screwed tightly within the shell. Finally, the bearing'surfaces K K may be integral with the carrier J, if desired; but it is preferred to convert said bearings into separate valves, so as to be readily detached from the carrier when worn out or injured.

I claim as my in'vention 1. The combination, in astraight-way valve, of pipe-connectionsBBinline with each other, a rock-shaft, G, parallel with the axis of said connections, and avibrating carrier, J, secured to said shaft, the free end of said carrier being provided with a pair of valves, KKQthat close against inclined, seats a a at the inner ends of said connections, substantially as described.

2. The combination, in a straight-way valve, of pipe connections B B in line with each other. a rock-shaft, G, parallel with the axis of said connections, and avibrating carrier, J, secured to said shaft, the free end of said carrier being provided with a pair of loosely-coupled valves,. as M M, that close against the inclined seats a to at the inner ends of said connections, substantially as described.

I 3. The combination, inastraight-way valve, of pipe-connections B B in linewith each other,

a rock-shaft, G, parallel with the axis of said connections, and avibrating carrier, J, secured to said shaft, the free end of said carrier being provided on its opposite sides with an upper pair of wings, S S, and a lower pair of wings, s s, that surround a portion of the margins of the loosely-coupled valves T T, which valves close against inclined seats a a at the inner ends of said connections, substantially as described. r

4. The combination, in astraight-way valve, ofthe vibrating carrier J, provided with upper wings, S S, lower wings, s s, ties U Uand bosses V V, and the loosely-coupled valves T T, furnished with circumferential grooves t t and bearings v 1), as and for the purpose described.
