'VALVE.

No. '866,906.1 specification of Letters Patent.

pplication filed January 29, 1907. I Serial No. 354,748.

To al# it may concern:

United4 States, residing at Mansfield, inthe county of Riehland and State of Ohio, have invented certain.

new ndluseul Improvements in Valves; and I do declare the following to be? a full, clear, and exact description of the invention, 4suchas will enable others skilled in the art to use the same.

This invention relates to improvements in reciprocating val-veav which it appertains to make and The obiect ofthe invention'is to provide a valv'e of this character,the construction or' which -affordsa rrn and tight engagement. with its seat when closed rhere-v 'i A further object is to construct a valve seat in such With. the above `and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinaiter described and claimed. 4

`In the accompanying drawings1-Figure l is a vertical sectional view through a valve constructed in accordance with the invention; Fig. 2 is a horizontal sectional view on the line 2 2 of Fig. 1;` Fig. 3 is a similar lview, taken on the line 3-3 of Fig. 1 and looking toward the lower side of the valve-seat; Fig. 4 is a detail, Vertical sectional view through a portion of the valve and seat, showing the valve in an open position. y p f Referring more particularly to the drawings, 1 denotes the valve casing, which may be of any suitable form, but which is here shown as an lordinary globe .valve casing. In the casing 1 is arranged avalve seat' 2, said sea-*comprising an outer annularbearing wall outer bearing wall .3. The lower portion of the outer bearing wall-3 and the lower'portion o the adjacent wall of the bearing ring 4 are straight and parallel with each other, as shown at 7, while the upper portion of said walls flare or are inclined outwardly in opposite directions, 'as shown at 8.

Adapted to be engaged with the seat,2 is a valve 9,

said valvebeing cup-shaped or provided on its lower side with a depending annular flange 10. The innerV and-outer walls of the lower portion or' the flange l1Q are straight and parallel with each other, as Vshown at 1.2, while the upper portions ofthe flange are provided with outwardly'tlaring o'r inclined walls 13. When l l the valve is eng-ged with its seat.. the straight lower Beit ln'iown that I, JOHN H. BERRY, a citizen of the the outer bearing wall 3 of the seat` while the upper 60v outwardly-dared portion of the a'ngc l0 will engage the outwardly flared or inclfinedportions 8 .of saith bearing walls of the seat, thus providing for a firm and tight engagement between ,fthe valve and its seat.

- The inclined portions of the' walls of the seat will 65 facilitate the removel and discharge of any accumulations of refuse by the flange 10 ot' the valve when `*engaged therewith, thuspreventing the clogging of v `the valve or interfering with the operation 'of the same.

In thc uppcr portion of the valve is formed an intcriorlythreaded annular recess in which is adapted to .be swiveled the lower anged end of a valve stem 14. This stem 14 is' secured in'swivelecl engagement with the valve by'nreans of a flangedexteriorly-threuiL l ed sleeve l5, which is screwed into the threaded recess of the valve and into `engagement with the fiange on the inner end of the valve stem, as shown. The

stem 14 is provided with coarse operating threads 15, which are adapted t0 be engaged with an interior-lythrcaded sleeve or cylinder lo formed on the cap 17,

which is screwed into the upper open end of the valve casing, as shown. The upper end of the sleeve' 16'is provided with a packing gland 18, through which the stem 14 works. The-upper end of the stem 14 is here shown as being provided with a hand-wheel 19, by

means ol' which the same is screwed inwardly or outwardly to close or open the valve. y

A valve constructed as herein shown and described vmay be employed in any capacity where a valve of this character may be used, the same, however, being especially constructed for use as a blow-of-valve l'or steam-boilers.

From the foregoing description, taken inconnection with the accompanyingdrawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes-in the form. proportion and the minor details of construction may be resorted tio-with? out departing .from the'principle or sacrificing any of 100 the advantages of thislinvention, as defined. by the appended claims. A

Having thus described my invention, what I claim as new and desire to secure by` Letters-Patent, is:-

1.The eombinatlionvof a. valve easing, a seat formed 195 and having a depending' ange to enter the channel bef 110' l `tween the spaced walls. y i

2.('1he` combination with a valve casing, of a seat tornietl therein and comprising a pair of spaced continuous valveseat, and' the walls having parallel lower portionsl walls provided with connecting lugs, said lugs being spaced relatively to provide discharge openings leading from the and beveled upper portions, a valve arranged to close on said seat and having a depending flange Ato seat between said walls, said flange having the low'erportion of its inner and outer faces parallel and the upper portion of said faces divergently inclined to conform to the beveled portions of the walls, and means for operating the valve.

3. The combination, with a valve casing, of a seat formed therein, said seat comprising an outer annular bearing wall and an inner bearing ring spaced from said outer bearing wall to form an annular space or channel, integral lugs. to Yconnect said inner ring with the outer an- .'nular wall of the seat, said lugs forming openings. or

spaces between themselves for the discharge of refuse, and

a valve adapted to be engaged with said seat, substan` tially as described.

4. The combination with a valve casing, of a seat formed therein, said seat comprising an outer annular bearing wall and an inner bearing ring spaced from said -outer bearing Wall to form an annular space 0r channel,

integral lugsto connect said inner ring with the outer annular wall of the seat, said lugs 'forming openings or lspaces between themselves for the discharge of refuse, and a valve having an annular bearing flange adapted to be engaged with said inner bearing ring and outer bearing wall, substantially as described. 1 y..

5. The combination with a valve casing, ofa seat formed therein, said seat comprising an outer annular bearing wall and an inner bearing ring spaced from said outer bearing wall 'to form an annular space or channel, the upper portion of said outer bearing wail and the adjacent wall oi said bearing ring being beveled or dared outwardly and having parallel, perpendicular lower walls, integral spacing lugs to connect said inner ring with 4the outer annular wall of the seat, said lugs forming discharge openings between said parts oi.' the seat, and a valve adapted to be engaged with the latter, substantially as described.

6. The combination with a valve casing, of a seat formed therein, said seat comprising an 'outer annular hearing wall and an inner bearing ring spaced from said outer bearing wall to form an annular space or channel, the upper portion of said outer bearing wall and the adjacent wall of said bearing ring being beveled or dared outwardly and having parallel, perpendicular lower walls, lntegral spacing lugs to connect said inner ring with the outer annular wall of the scat, said lugs forming discharge openings between said parts of the seat, and a valve having `an annular bearing flange, the inner and outer walls of the lower end of which arestraight and parallel, said walls iiaring outwardly toward the upper end of the valve, substantially as described.

In testimony whereof -I have hereunto set my hand in presence of two subscribing witnesses.
