G. J. HENRY SPRING FLOATED VALVE HEAD I Filed 001,. 13, 1945 Patented May 17, 1949 UNITED STATES PATENT OFFICE SPRING FLOATED VALVE HEAD Guy J. Henry, Arlington Heights, Ill.

Application October 13, 1945, Serial No. 622,163

1 Claim. 1

This invention pertains to improvements in a floating valve seat of the general type illustrated and described in my U. S. Patent No. 1,693,032, dated November 27, 1928.

It is an object of the present invention to provide a valve including a valve seat which is positively acting in both directions, being controlled by a hand operated, screw-type stem, wherein prevention of abrasive action on the valve during seating and minimization of the force required to close and open the same are effected.

Another object is to provide a valve of the above type which insures repeated accurate seating the valve without damage thereto and resultant leakage.

A more specific object of the invention is to provide a floating valve seat, wherein a spring is embodied in the structural details of floating support of the seat, to the end that chattering and noise in action are avoided, particularly when the valve is employed in a suction line.

Yet another specific object is to provide a spring fioated valve of the type described, having a roller bearing, swivel action to minimize friction and facilitate seating and unseating.

The foregoing statements are indicative in a general way of the nature of the invention, but other and more specific objects will be apparent to those skilled in the art upon a full understanding of the construction and operation of the device.

One embodiment of the invention is presented herein for the purpose of exemplification, but it will be appreciated that the invention is susceptible of incorporation in other modified forms coming equally within the scope of the appended claim.

In the drawings,

Fig. 1 is a fragmentary view in side elevation,

' partially broken away and in vertical transverse section, illustratin a valve seat and associated stem embodying the resilient floated-seat features of the invention;

Fig. 2 is a view in transverse section on a line generally corresponding to line 22 of Fig. 1; and

Fig. 3 is a view in vertical section through a valve fitting, illustrating the combination of the improved Valve seat of this invention therein.

In my Patent No. 1,693,032 identified above, there are illustrated and described certain improvements in a floating or swiveled valve seat, whereby a substantial minimization of the force required in opening and closing the valve is obtained. The present improvements relate to further improvements in the aforesaid type of valve by elimination of noise and chatter apt to accompany the use of such a lost motion or floating construction in certain connections, for example, in the control of a suction line.

With the valve in the open condition, under such conditions, it is obvious that variations in vacuum-induced flow of fluid will tend to result in some chatter and noise at the seat which it is an object of the present invention to avoid. Further, the improved structure enables a more easy and satisfactory manipulation of the valve, since its initial engagement with the controlled port may be readily detected by feel, notifying the operator that contact has been made and only slight further rotative action is necessary. Furthermore, accuracy of initial seating and repeated reseatings at the same point on the valve is assured, so that a source of possible leakage arising from damage to the valve seat is eliminated.

Referring to the drawings, the reference numeral It in Fig. 3 generally designates an L-type valve fitting of conventional construction providing a valve chamber II, a vertical inlet l2 and a lateral outlet l3. An annular port I4 in line with the inlet projects upwardly in chamber H, with which port the valve member I-5 engages in the operation of the device. Member [5 has an actuating stem l6 threaded externally at I! for engagement with the housiig l0 and is controlled by a hand wheel 18 on the stem externally of the housing, all in conventional manner.

Referring to Figs. 1 and 2, the valve member l5 includes a main body I9 which, on the lower face 20, carries an inlay or insert 2| of relatively soft metal to seal port M. This insert becomes indented somewhat in repeated engagements with the port M to provide an effective seat; and the provisions to be described insure the accuracy of reengagement of said insert seat indentation with the port, whereby misalignment attended by damage to the insert, and resultant leakage, are prevented.

Member [9 is bored or otherwise hollowed centrally on its upper end to provide a. circular recess, or chamber, 22 for the floating reception of the lower end 23 of stem l6. Said lower end is of a diameter less than the diameter of recess 22 and carries an annular groove 24 with which the horizontally disposed roller-like pins 25 coact. Said pins are received in the radial openings 26 through the wall of the valve member l9, and are held in retaining engagement with the valve body in groove 24 by a resilient split wire ring 21 encircling the body. A downwardly flared shoulder 28 on stem 16 immediately above
