Application tiled Apri125, 1917. Serial No. 164,508.
of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful )improvements in Valves, of which the following is a specification.
This invention relates to valves and aims to provide improvements therein.
The present invention provides what may be called a "-packless valve and is especially applicable to use in vacuum systems and in house steam or hot water heating systems.
A. eXible diaphragm is placed between the operatin part and the valve proper; ac-
cording to t e present invention this diaphragm 'is so arranged .and related te the other lparts of the device that a minimum of movement thereofis required in opening er closing the valve, so that the strain on lthe diaphragm, and consequent liability to breaking or cracking, is extremely slight.
body of the valve;
'lhe general construction of thel valve is` simple.
'llhe invention will be more fully described in cdnnection with the accompanying drawings, illustrating one embodiment thereof. l
Figure 1 is a vertical section illustrating' the parts in position corresponding to the closed position of the valve;
Fig. 2 is a similar view illustrating the parts in the position corresponding to the open position of the valve;A
Fi s. 3 and 4 are detail views, showing respeotlvely a plan view and an elevation of a part of the handle Fig. 5 illustrates in plan and elevation a key-plate used to secure the handle,v to the Fig. 6 is a detail view showing in elevation the front of the valve proper and the 'end of its operating lever 4- Fig. 7 is a top plan view of the valve,
with the handle removed;J
Fig. 8 is' a detail view illustrating the mounting of the lever which operates the Fig. 9 is a detail view of a guide ring.
Referring to said drawings, numeral 1 indicates a valve casing, preferably made in two parts, 2 and 3, connected, for example by a threaded sleeve 4.
Numeral 5 designates the valve proper within the valve casing. rlhe valve proper 5 1s conveniently formed with a stem which may be guided by a guide ring 7 inserted in the valve casing. rll`he valve proper also preferably has a sleeve 8 thereon which telescopes upon a projection 9 from the inner side of the valve casing.;y The sleeve 8 and rod 9 preferably have shoulders 10 and 11 thereon, between which may be arranged a spring 12 adapted to normally press the valve proper toits seat. The proJection or rod 9 may be conveniently formed with a stub 13 which fits within a socket 141 in the valve casing. The spring 12 acts'to hold the stub 13 in the socket 141, `and hence to hold the rod or projection 9 in Iplace.
rlhe valve proper 5 is moved to and from its seat by means of a pivoted lever 15 having a long arm 16 and a short arm 17, the.` lever belng preferably provided with knife edge trunnions 18 fitting within bearings 19- formed upon the inner side of the casing 1 (Figs. 7 and 8). The long arm 16 of theV lever 15 is bifurcatedat its end (Figs. 1 and 6), and lits around the valve sleeve 8 between -the back face of the valve andthe flange 11, and carries the valve proper with it, as it is moved toward and away from the seat.
The Short arm 17 of thelever 15 is preferably provided with a roller 20 which fits within the cam groove 21 (Figs. 1, 2 and 3)v within a rotatable cap or plate 22.
'lhis cam groove is formed with a gradual rise or incline, the frictional force between the .lever and groove being greater than the (rig. 4.) in para 22, andan nasse (Fig. e),
formed in the casing 1, the Vpates 24 being conveniently held in place by the insulating 4covering 23.
Between the operating lever l5 and thecasing 1 there is placed a 4Heiiibl'e diaphragm 27. This diaphragm is preferably attached to the leve1'5 at or near its pivotal plane. The diaphragm is preferably a tubular corrugated diaphragm and is preferably tapered or reduced in diameter at the point Where it is connected to the lever 15. It may be attached to the lever in any suitable manner,
it being here shown as having its edge portions fitting Within a groove 28 cut Within the lever and the material swaged down upon it. The oppositeend of the diaphragm 27 ispreferably formed With a iange 30, and this iiange 30 is conveniently clamped between the portions-2 and 3 of the valve casing. The construction of the diaphragm as thus described, and its connection to the lever and casing facilitates the easy assembling of the device.
Operation: To open the valve, the plate 22 is turned, and the groove 21 therein causes the lever 15 to rock in its bearings 19. A slight movement of the short arm 17 of the lever gives multiple movement to the long arm 16 of the lever. A comparatively slight amount of movement of the short arm 17 of the lever 15 in the proper direction is thus sufficient to open Widely the valve proper 5. The gradual rise of the cam groove 21 enables the lever to be moved with an ordinary e'ort against a fairly strong pressure of the spring 12.
Moreover, the diaphragm, being connected to the lever near its pivotal plane, undergoes a movement which is'relatively slight, as compared With the amount of movement of the end of the arm 16 of the lever. rlhis slight movement of the diaphragm being distributed among the several corrugations of the diaphragm, causes a very slight movement of the dia hragm, andhence exerts very little straln upon the diaphragm.
There is hence little danger of the diaphragm breaking under use.
To close the valve 5 the cap 22 is simply rotated in a direction opposite to the opening movement. The movement of the valve proper 5 is assisted by the pressure of the spring 12.
It will thus be seen that the valve is of very simple construction, is susceptible of being readily assembled, and enables the diaphragm to be used under conditions which entail very little movement thereof and strain thereon.v
