In the drawingS- 1 vFigural is a central,vertical'sectional viewi of the improved-valve. 7

V Figure 2 ;is asectional plan-view, the view being taken on line, 2+2 of Fig. 1. .7 Referring now "to these drawings, the valve ,7 structure selected to illustrate the invention is a compression valve,.that is, avalve closing against: the pressure1I1qtl1e=l1ne,;but their:-

? yention is not to be restricted-to' this, butmay 7 1e employed where the -valve .wil l close with the pressurein theiline; As shown, the improved valve.;stru'ctureI includes) a casing 1, formed at itslower end with threaded projectionsQ, 3 to? receive the inlet pipe 4 land into' the partition. j The casing is provided with an upwardly extending tubular projection -9' interiorlyfurther object of the invention to lng. r

' In this casing is'positioned thegvalves, mechanism "and the actuating mechanism outlet pipe 5 respectively. A passage 6 is" formed in the bottom'of the casing divided by a partition 7 inwhich is provided a valve seat in the form of a hollow block 8 screwed threaded, as indicated-at 10, to receive a plate orblock 11. The casing, also, includes a sleeve 12, this sleeve being spaced from the -upper part of the extension 9, as indicated at 13, this sleeve extending above the top of the extension 9. VVhi'le this sleeve might, if desired, be formed integral with the casing 1, for convenience in manufacture and assembling it is made separately and is pro -'1" on to a threaded flange15'formed on the cas- ,o

therefor, and this mechanism is of-suchf character that the valve is closed against pressure in the line, the actuating mechanism for the valve operatingto lift the valve from its seat, the valve being returned to its seat an actuator for'liftingthe valve which will. operate with a vertical sligding movernent.

that no sidewise projecting parts are neces-g' 'sary and asimple andicompact structureis provided, one that is out of the wayand takes up very little'room, Furthermorethe mechanism will be such that the operating parts can be removed from the topof the casing so as to 'provide ready accessibility for inspection and repair. I In the particular.constructlon illustrated 16 and a stem 17. In the best constructions playwhich assist-s in the seating of the valve.

- there 1s provided-a valve lncluding. a. head As shown the head 16 is provided with a'fac 18 of rubberonthe i liken secured to the, l head by a screw 19, thisjrubberfa'cingseat- 3 Qing 'on the seat S. [Screwed ingthe headfl6 :at; its other end is a block '20 h aving ;al

shouldered recess 21 which receives a collar 22 on the end of the valve stem17, the stem thus having a slight play in the head.

The valve stem passes through the plate or block lO through a suitable stuffing gland 23', packing 2-l being provided about'the stem and packing 25 also being provided between the top of the extension 9 of the casing and the plate or'block, the block bcingprovidcd with a flange 26 under which the packing 25 is placed. The valve 1s automatically returned to its seat by means of a spring-27 which bears' against the head of the valve and the under side of the stuffing gland 23, the valve being opened against this sprlng;

With this construction a steady closing movement of the valve is obtained and, the

valve closing against the pressureofthe line,

water hammer is prevented.

A mechanism for lifting the valve will, as before stated, include an actuator which has r a vertical or straight line movement so that it can be operated by the direct pressure .as

for instance, by the foot of the user. In the construction illustrated, this mechanism in cludes an actuator in the form of a hollow plunger 28, this plunger being provided with 'a' cap 29. The walls of the plunger have a' vertical sliding movement in the space13,

' "TThisplunger cooperates with the valve lifting devices which, as shown, incl ude a pair V of lifter arms 30, 31, pivoted at 32 in i 35 before referred to, formed between the ex tension 9 and the sleeve 12 of the casing.

brackets formed on the top of the plate 10, before referred to. These lifter-arms at their lower ends have an inwardly directed toe 34 which bears'against the under side of a collar 351011 the upper end ofthe valve stem17,-before referred to. Asfthese lifter Varmsa-re rocked outwardly 'ontheir pivotsted and the plunger is pro the valve is lif vided with means for effecting this, shown ,in the fernfof a cone shaped projection 36 depending from thei nner surface of the cap betweentheupper ends of the lifter arms; To facilitate the movement ofthe lifter arms they are orma-y be provided with rollers37. Where these valves are positioned beneath the flooring of a room, a use for I which they are particularly designed, means I 'are'f'preferably provided for'preventing' acci-' dental water fromgettin'g into the interior of the valve. A convenient way for effecting" this is that shown, in which'thep'lunger cap is provided with'a depending skirt or flange cated at 39, and a set screw 40 is passed through the sleeve wall so as to extend into this recess. 7

In valves embodying the invention in its best. form, particularly where the valves are to be set beneath the ,fioor,a floor plate is provided surrounding the'sleeve 12, this floor plate being indicated by the numeral 41. i As .the distance between the service line and the .fioor generally varies somewhat, in order 'to provide for the correct positioning of the plate, the plate is made adjustable with respect to the casing. As'illustrated the plate is formedwith adepending ,threaded oollar e2 which screws on to a threaded portion 43 formed on the outer wall of the sleeve 12.

,WViththe construction shown and described a very simple and efficient valve has been provided, oneWh-ich will be'si-mple in operation, which takes up but littlespace, and one which j can be set in the floor so as'to project but slightly above the floor su-r'facethus being inconspicuous and out of the way and in which 7 access of accidental water is'prevented.

lv hilet he valve has been shown in its pre- 1 ferred form,- it will be understood; that changesand variations maybe made in the specific construction shown and described without departing from the spirit of the invention. r
