Patented Apr. o. H9315.

Application led I'ay 9, 1914i. Serial lilo. 837A?? T 0 all trimm it may concern Be it known that l, HoMniz S. Benson, a citizen of the United States, residing at li/luncy, in the county ci: Lycoming and State of Pennsylvania, have invented new and useful improvements in Gate Valves, of which the following is a specification.

This invention relates to improvements in gate valves.

ln carrying out the present invention, it is my purpose to provide a gate valve which will embody, among other features, a casing having a I'iuid passage formed there through, a seat formed therein across the. passage, gate movable into and out ci the passage to obstruct and open the latter and conc-ting with said seat and comprising tivo longitudinal sections and a Wedge block interposed between said sections and movable simultaneously therewith in the opening; and

closing of. the valve and independently there ot' to force the sections into binding engagement with the seat whereby a fluid tight joint will be effected, and to release said sections.

lt is also my purpose to provide a valve ofthe class described 'which will embrace the desired features of simplicity, e'lliciencjv and durability, which may be manipulated with ease and convenience and which may be installed and maintained at a minimum expense.

With the above and othei` objects in view7 the invention lconsists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim.

ln the acconipsolving,T drawings; Figure l is a view in side elevation of a gate valve constructed in accordance with the present invention. Fig. 9 is a vertical longitudinal sectional` View therethrough. Fig. 8 is a vertical cross sectional view therethrough. Figi'. i is a horizontal sectional view through the valve. Fig. 5 is a .sectional vie.7 on the line oi" Fig. 2. is a collec tive view of the gate showing the component parts thereof in .perspective 7 is a fragmentary top plan View of the gate.

Referring now to the drawings in detail., l designates a casing;` formed longitudinally with a 'fluid passage 2 and having the oppo site ends thereof equipped with outwardlyfv projecting circumferential flanges 3, 3 Where by the casingv may be connected in a. ci pipe. Surinounting the casing l prei"- erably formed integral with the upper Wall thereof is a bonnet i arrangedapproxiy mately centrally. ofthe casing and of a.

width Correspendingv with the similar cliniension oi2 the casing. ln the present instance, this bonnet is, composed oa bottom inner section 5 and top or outer section 6 an( l the-.confronting edges of the sections 5 and (i are Atornio-d with outwardly extending flanges '.7 provided with bolt holes through which are passed securing` bolts 8 whereby the sections are held in bonnet'formation. lhe top wall oi the casing l. approximately ,cent-rally ot the bonnet-is formed With a transverse slot 9. while the inner surfaces of the opposite side Walls contiguousthe eX- treinities of the slot il are 'formed with vertical grooves l() communicating at theloiver extremities with a transverse groove ll formed in the inner iace ot' the lower Wall of the casing. opposite side Walls of the grooves l0 and the latter walls taper downwardly and merge into side Walls the groove ll, the groove l1 being relatively narrow compared with the Width oi' the slot 9 .eo'that a tapering is formed.

litovable into and out of the seat close and open passage 2 is gate ,l2 coinrisi'nn. in instancertivo longiiulinahsections i3.. T13 tapering downwardly in cross section Hifi having the outer faces "hereof adapted to against the adjacent falls of the slot il, grooves l0' and groove upper ends thereof bent at right angles to themselves as at lo, and extending toward each other, such lugs cooperating` with each other `to forni a bonnet, while extending upwardly from the top end of the wedge block l i are similar lugs 17 spaced apart and forn'iing a bonnet.

ilotatably mounted `within the upper end of the-bonnet -l and evtendingl upwardly therefrom is a tubular valve stein section 1S having the lower end the/recil threaded interiorly as at i9 and threaded into ine stern sectionl and depending therefrom within the bo ed stemnet 4; is an exteriolgly threadsectiiin 20 having the lower end thereol equipped with a head 2l disposed within the non-circular Loneet formed by the lugs l5. Passed through the axially alining bores et' the stem sections 1S and 20 is a stem E22 havingv the upper end thereet terminating above the adjacentl extremity ol the stein section 1S and the lower end formed with a non-circular head Q3 disposed within the bonnet formed by the lugs 17 on the upper end ot the wedge block 14. ln the present instanee, the lower extremity ot the som 22 is screwthreaded and enthe threads formed in the bore of the stem section 20 so that when the stem is rotated in one direction the wedge block lflwill be moved downwardly to spread gate sections SLIR, while when the on ot the stem 22 is revesed the, wedge block will be elevated to permit the gate to contract. Fixed to the upper endv ot the stem section 18 is a hand wheel 23, while secured to the upper .eX- tremity of the stem 22 is a hand wheel 2l. The stem sections 18 and 2O constitute a telescoping valve stem and when the sectidn 18 is rotated in one direction under the action oi' the hand wheel 23, the threaded stem section f2() moves into the section 'IS thereby elevating the sections 13 and wedge block il of the gate 12, the stem 22 sliding upwardl)v within the bores in the teleseoping sections ol the valve stem. When thedireetion of rotation of the telescopic stem is reversed the section 20 moves downwardly within the bonnet thereby sliding the gate into the seat and sage 2 through the easing l. the seating ot the gate, the stem Q2 is rotated to lower the wedge block 18 whereby the outer faces ot the sections et the gate bind against the adjacent walls of the seat to torni an eii'ective fluid tight joint whereby leakage around the gate is eliminated. `When it is desired to elevate the gate to open the valve the stem 22 is revolved under the action oi the hand wheel 24- to elevate the wedge block le so that the sections ot the gate willb'e relieved of the iniluence of the wedge. The telescopic section is now etuated to elevate the gate and the latter moved out of the passage whereby the fluid eontrolled by the valve is iii-ee to How.

The upper end oit the bonnet i is preterably equipped with a stufling bex Q5 surrounding he stem section '18 and forming a ,-iuir1 tight joint, while the hand wheel 2? et telescopic stem is also equipped with s iliing bony QG whereby a fluid tight joint be .'een the telescopic stem and thev wedge block steml is formed.

The eon't'ronting walls ot the seat and d1 ection ot rota across the pas- Succeeding l Listen gate are preferably lined with wear resisting packing material 27 in order to increase the elliciency of the valve and prolong the lite thereof, while a pet cock 28 is threaded into the bottom wall of the groove ll in order that any air or water therein may be drained oil" when necessary or desired.

From the Yforegoing description taken in Connection with the accompanying drawings7 the construction, mode of operation and manner of employing my improved gate valve will be readily apparent. lt will be seen that I have provided a gate valve wherein the gate may be readily moved to closed and open positions and locked in closed position.

The opposite side walls ot the bonnet 4 a; preferably formed with vertical grooves 29, 29 forming continuations of the grooves l0 in the side walls of the casing l and acting as ways to receive the opposite ends of the gate so that as the latter is moved into the bonnet in the opening of the valve movement thereof out of alinement with the seat is avoided.

While l have herein shown and described one preferred forinof my invention by way of illustration, l wish it to be understood that l do not limit'or confine'myselt to the precise details of construction herein Adescribed and delineated, as modification and variation may be made within the scope of the claim without departing from the spirit olE the invention.

l claim:

in a gate valve, a easing vhaving a passage therethrough and formed with a valve seat transversely thereof and-having vertical grooves formed in the opposite side walls thereof contiguous the valve seat, a gate movable into and out of said passage and seat and comprising two sections, a wedge between said sections and having the opposite ends thereoic slidably disposed within said grooves, means for actuating said wedge independently oit said sections to bind the latter against the adjacent Valls ot the seat, means for moving said sections and wedge simultaneously to open and close the valve, a lining` of wear resisting' material on the confronting faces of. said valve and seat, and a bonnet surmounting said casing and having the opposite side walls thereof formed with grooves alining with the i'irstmentioned grooves to receive said gate when the latter is moved out of engagement with the valve seat.

ln testimony whereof l atlix my signature in presence ot two witnesses.
