To all whom 'it 'may concern.'

Be it known that I, Aootrn Sonori, Jr., a citizen of the United States, residing at Chicago, in the county of Gool: and State of Illinois, have invented certain new 5 and useful Improvements in Steam-'Traps of which the .following is a specification.

This invention relates to steam traps or draiuers of that character which are designed to collect and discharge or drain off the water of condensation resulting l in any given steam containing receptacle or system of piping to which the trap may be applied, and more particularly it relates to improvements in that class of such drai ners known as gravity traps and which may be either return traps for discharging the water of l condensation from a lower to aphigher pressure and wherein a movable receiver or chamber collects the water when in a raised position and then descends under the weight of the water collected to thereby admit steam to expel the water, and usually to return it to the heilen-or maybe Utank traps designed to discharge the water from a higher to a lower pressure, and which are similarly constructed except that the collected water flows out of the receiver under the pressure of the system drained when the outlet is opened b y the descent of the receiver.

The object of the invention is to provide an improved constriurtion in draincrs of this character', more efiicient and economical in its working and less liable to get ont of order than any similar device heretofore known, and

3 0 to this ond it consists in the matters herein set forth and morel particularly pointed out in the appended claims.

In the accompanying drawings, Figure l is atop plan view of an autonnttic return trap or drainer constructed in accordance with my improvements. Fig. 2 is a side elevation tlmrcof.

Referring .first to the return trap illustrated in Figs. 1|.-l2, inclusive, Il designates a water receiving chamber mounted to oscillate upon a hollow trunnion 2 that is supported within bearings 3 on any suitable frame work 4. The same trunnion 2 also supports a weight 5 55 which is arranged opposite to the receiver l and is of sufficient weight to over balance the latter when empty.

As herein sh own this weight is adjustably secured, by a set screw (i or otherwise, upon an arm 7 which projects laterally from the trunnion, and the limit of movement 6() of the trap in one direction is arranged to be varied as desired by means of an adjustable stop 8, consisting in this instance of a set screw tapped into the weight and adapted to contact with the frame l of the trap when the weight swings down, a similar stop 9 being herein 65 shown as provided on the under side of the receiver 1 to adjustably limit the movement of the trap in the opposite direction.

The receiver itself is herein shown as made of hollow spherical form and is bolted to the flanged end of a hollow arm l0 that leads off from the trunnion 2 at a point nearly o pposite the weight supporting arm 7. The passage through this hollow arm l0 is in communication at its inner end with the interior of the hollow trunnion 27 while from its outer end a pipe or passage 75 Il leads upwardly within the receiver l. to a point near the top thereof, this pipe o1' passage ll in connection with the communicating passage through the hollow trunnion 2, forming an inlet by which steam is admitted to the receiving chamber I. Water is admitted l to said chamber, and is also discharged therefrom, through a port l2 located at the bottom of the chamber and communicating with a flexible tube I3 leading to water inlet and outlet pipes I4 and I5 in which ch eck valves IG'and I7, and a strainer 18, if desired, are suit- 85 ably provided. The tubing I3 will preferably be a flexible metallic tubing and will be soldered or otherwise secured at one end within the mouth of the port l2 of the receiver to form a watertight joint therewith.

Its opposite end is herein shown as similarly inserted and secured within a bracket I9 on the base plate, into which bracket the connection leading to the inlet and outlet pipes ld and l5 is also tapped.

Admission of steam to the receiver through the .hollow trunnion 2 is controlled by an oscillatory valve V lo- 95 cated within a valve chest 20 into which the trunniou enters through a stuffing box 2l.. This valve comprises a valve plate 22 secured to and turning with the trimmen, and an opposing valve seat 23 carried upon the inner face of .the head 24 of the valve chest and l00 through which steam inlet and outlet ports or passages 25 and 2G lead out respectively to steam and

veut pipes

27 and 28. The inner end of the steam port 25 is located at some distance from the axis of the trunnion,

and that portion 29 of the valve seat surrounding said 105 port is finished olf to a plane surface at an angle to said axis. The opposing portion 30 of the valve plate is correspondingly finished off to a plane surface at the same angle to the axis, and when brought into contact by the oscillation of the trunnion, these two surfaces will exactly coincide and close the steam port. Similarly the inner end ofthe vent port 26 is located at some distance from the axis of the trunnion and the surface 3l of the valve seat 23 surrounding said vent port is finished off on plane at an angle to the axis of .the trunnion but at a reverse angle from that of the surface 29 surrounding the steam port, while the opposing surface 32 of thc valve plate 2O is finished off on a plane at the same reverse angle to the axis, and as the trunnion is oscillated back to bring these surfaces in contact they will in turn exactly coincide and close the vent port. The movement of the valve which thus closes the steam port will open the vent port, and vice versa, the valve movement which closes the vent port will open the steam port, these movements correspond respectively with the rising an d falling movements of the receiver 1. When the receiver is raised and the vent port is open and the steam port closed, the water of condensation drainingr from the connected system of piping will enter the receiver through the inlet pipe 14, past the check valve 1G and gradually collect therein, and eventually the weight of this collected water will become su fiicient to overcome the propender-ating gravity of the weight 5 and the frictional resistance on the trunnion. When this point is reached, the receiver will swing down and thus oscillate the valve plate 22 so as to close the vent and open the steam port, and the entering steam will then exert its pressure on the surface of the collected water in the receiver and force it out through the outlet pipe 15 past the check valve 17. This discharge of its contents will in turn lighten the receiver until its weight, together with the frictional resistance on the trunnion becomes less than the gravity of the weight 5, whereupon the latter will descend, thus raising the receiver and closing the steam and opening the vent port. The opening and closing movements of the valve do not, however, exactly coincide with the rising and falling movements of the receiver since, in order to render the valve travel and time of movement as short as possible, and to permit the moving parts to acquire a considerable momentum before any very great resistance is offered to their movement, a certain amount of lost motion is allowed between the valve plate and trunnion. This is provided for, as hereby shown, by mounting the valve plate upon the end of the trunnion in such manner as to permit of its having a limited oscillatory movement thereon, such movement being herein shown as determined and limited by stops in the form of set-screws 33, the inner ends of which extend into and alternately engage the ends of a circumferential slot 34 on the trunnion. No motion will thus be transmitted to the valve plate until the unbalanced weight has overcome the friction on the trunnion and the receiver has started well along on its rising or falling movement. Then the end of the slot 34 will strike the one or the other of the stop-screws 33 and suddenly and rapidly throw the valve over to close the open and open the closed port and admit or exhaust the steam accordingly.

As herein shown, the valve plate 22 is, as a matter of convenience in construction and for the sake of easy re` moval and repair, made with a separable hub section 35 to which the valve seat is rigidly secured by bolts 36,

these bolts dropping into slots 37 in the hub section so that it is only necessary to loosen them slightly in order to lift the valve plate free from the hub. To the same end the valve seat 23 is herein shown as made separate from the head 24 of the valve chest and detachably secured thereto by bolts 37, a key-38 being applied between the contacting surfaces of the seat and head to insure the exact positioning of the alinement oi the seat. A removable cover plate 38 secured over the chest by bolts 39 and forming the top of said chest, insures ready access to those ports of the inclosed valve beneath.

In the tank trap shown in Figs. 13-16, inclusive, the construction is generally the same as in the return trap hereinbeforedescribed except that the receiver 1 is inverted, while the oscillatory valve V within the steam chest is provided with but a single port 4() which leads to a discharge pipe 41, the steam connection being omitted entirely. The flexible tubing 13 enters the receiver in this case near its top, instead of near its bottom, and the pipe or passage 1l which connects with the interior of the hollow trunnion 2 leads downwardly within the receiver to a point near the bottom thereof instead of upwardly toward the top as before. The flexible tubing serves solely as an inlet for the entering water of condensation, and is connected through pipe 14 and strainer 18 with the system to be drained, but is devoid of any outlet connection 0r check valves, these being unnecessary. The entering water graduallyl fills the receiver until its weight overcomes the preponderating gravity of the weight 5 together with the friction of the stuffing box and bearings. Then this occurs the receiver descends and so moves the valve V as to open the outlet port 40 and permit the water accumulated in the receiver to pass out through the pipe 11, hollow trunnion 2, valve chest 20, and outlet port 40 under the pressure existing in the system with which the trap is connected. Then just before the water has been forced out to such an extent as to uncover the lower end of the pipe 11, the preponderating gravity of the weight 5 will in turn overcome the weight of the receiver and the friction of the stuffing box and bearings and again oscillate the valve so as to close the outlet port, thus preventin'g the steam from blowing through, and permitting the condensation to again collect in the receiver.

My improved traps are particularly advantageous in that they require the use of but a single stuiling box which also serves as a means of adjusting the friction on the trunnion to the exact amount required for the proper operation of the device. The improved form of valve set forth is exceedingly simple in its nature and is not likely to get out of order, and owing toits peculiar construction, its opposing surfaces constantly tend to wedge themselves more closely and to thus render the valve increasingly tight and less liable to leakage. Various changes, may, however, be made in the details of the construction shown without departure from the broad spirit of the invention claimed.
