' To all whom it may concern:
Be it known that I, PETER LORD, a subject Iof the Kingof Great Britain, and a resident of the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improve-v ments iunValves; and I do hereby declare that the following isa full, clear, and exact description ofthe same.
The invention relates to improvements in valves, suitable for steam, water or the like and has for its object to devise a valve having a minimum number of parts andto improve upon the construction of a Huid valve in such a manner that it will be per- 'fectly fluid tight, cheap and easy to produce and durable as to'wear and tear.
Gne of the chiefjfeatures of the'invention is a connection between the valve and its stem whereby said valve will always adapt itself correctly to its seat even though -the closure to the open top of the casing,
including the stemoperating member, may
not be exactly inalinement with the valve seat.
' In the accompanying drawings, with the I aid of which the invention will be better understood, Figure 1 is a vertical section showing the invention applied to a well known style of globe valve for heating systems. Fig. 2 is a sectional plan view o n the line A-B, Fig. 1. Fig. 3 is a perspecti've'det'ail of the valve and stem. Fig.
4 is a vertical sectional view showing'the A invention alpplied to a faucet. Fig. 5 is a sectional p an'view on the line C-D of Flg. 4, and Flg. 6 is a sectional 'elevation i of a slightly modifiedform of connection between the valve and stem.
responding parts in each ligure.
Like. numerals of vreference indicate cor- Referrmg to the drawin and larly to Figs. 1, 2, 3, 1 is evalve casing, here shown of globe shape, having the Ainlet 2 andoutlet 3. v
'4 -is a` conical valve seat within the casl ing 1 between the inlet 2`and outlet 3.
`5 is an upward extension of the valve casing 1 having the internal thread 6 in alinement with the -valve seat 4 and the finished upperv surface 7 8 is the .bonnet having the flange 9 contacting the surface 7 the thread 10 engagparticuing the thread 6' of the casing, and the nut 11 by which the bonnet is screwed into the casing 1.
12 is a cylindrical orifice passingconcen trically through the bonnet 8 and terminat-y ing at its lower end in the conical surface finished plug seat 13.
14 is a plug whose body portion is shaped" to nicely fit the orifice 12 and whose lower fend is fashioned ,into a conical surface finished iiange 15 adapted to nicely fit the plug Aseat 13. The plug 14 has a central threaded 21 and 22 are a pair of lock nuts threaded on to the plug extremity 19 and adapted to secure the handle in place on the plug and at the same time to pull said plug upwardly so` that its conical lower end 15 engages the surface 13 fairly tightly, a spring washer .23 being disposed between the said nuts and the upper surface ofthe handle in order to maintain said contact.
24 is the valve. having a substantially spherical recess 25 approximately central of its height and widthv and guiding wings- 26.
27 is the valve stem having the left hand also having the thread 28 engaging the threaded orice 16 in the plug 14 and also having the ball 29 at its lower end substantiallytting the recess 25 in thevalve, thusl accomplishing a ball and lsocket connection between said stem and valve.
29 is a guiding lug extending laterally' from the stem 27 and at its outer end en. gaging a vertical guide way 30 cut in ythe Wall of the valve casing 1.
.In the use of this invention it will be seen that on turning the handle 20 to the right hand ,as usual in closing* a valve, lthe stem 27 will, by reason 'of its left hand thread, be
forced downwardly, as the handleturns the plug l4'an'd the plug in turn operates on the stem, said stem being prevented from rotating by reason of the lug 29a engaging the guide way 30. The downward travel of the 'Stem of course pushes the valve 24 on to the substantially central of. the height and width f said valve and ofthe seat when the valve is closed, as I have found in experi;
ments ,that this is really the only practicable method'by which" the valve willaccommodate itself perfectly, that is .to say, without leaking, on to its seat in circumstances where the bonnet and upper parts are not exactly in concentric alinement with the valve seat, which frequently-happens in the manufacture of all valves.
v In Fig. 4, the invention is to a faucet, there being practically no dierence in this arrangement except that the inlet and outlet are changed as necessary in orderf'to accommodate the invention to a faucet. A
It must be noticedxthat with this invention, the valve can be made of very little height and therefore neater in appearance. In raising the valve by turning thev handle to the left, the upper end of the thread 28 travels farther into the recess 1.7. f
In Fig. 6 a still further modification of the ball and socket connection'is shown, but here again the center of such connection is substantially central of the lheight and width ofthe valve and seat, the only vdiferl ence being that the ball is on the valve. and
the socket on the stem. v- The 'first described form, however is much preferred.
'shown applied l. In a valve, the combinationwith a casing having a valve seat therein,'of a valve stem longitudinally movable in said casing and having a leg engaging a vertical `slideway in said casing, a valve adaptedto engage said seat, ball and socket means connecting the lower end of said stem with the valve, substantially central of the height and Width of said valve (an'd of the 'seat when the valve is closed) and a rotary member having screw connection with said stem casing and lhaving a ball shaped lower end, a valve adapted to engage said seat and havying a ball recess central of its height and width` (and of the height'and width of the '50 having a lateral leg intermediateof its length engaging a vertical slideway in said seat when the valve is closed) said lower end being secured in said recess; and a rotary member having an, internal thread engaging an external thread on said stemfor imparting longitudinal movement tothe latter.
