UNITED STATES Patented September 22, 1903.
PATENT FIQE.
STEAM-TRAP.
SPEGIFIGATION forming part of LettersPatent No. 739,696, dated September 22, 1903.
Application filed March l8, 1903. Serial No. 148,377. (No model.) I
To all whom it may concern/.-
Be it knownthat we, JOHN GRIFFITH Mos GAN and VV'ILLIAM'BLETSO, citizens of the United States, and residents of Youngstown,
in the county of Mahoning and State of Ohio, have invented a new and Improved Steam- Trap, of which the following is a full, clear,
in operation, completely balanced, and arranged to insure a proper working of the trap and discharge of the water of condensation underanypressure of the steam entering the trap.
The invention consists of novel features aiid parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a longitudinal sectional elevation of the improvement'on the line 1 1 of Fig. 2. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1. elevation of the improvement. Fig. 4 is an enlarged plan view of the hollow pivot for the vessel to rock on, and Fig. 5 is a similar view of the sleeve of thevessel.
On a suitably-constructed stand A is secured by set-screws B a transversely-extending pivot 0, made hollow and formed at or near its middle with a transverse partition 0 (see Fig. 2) to form a steam-inlet C at one end of the pivot C and a water discharge or outlet 0 at the other end of the said pivot. The inner end of the steam-inlet O is adapted to connect by a port a in the wall of the pivot O with a port 71, formed in the wall of a sleeve or bushing D, secured in the transverse par tition D of a vessel D, preferably made cylindrical and divided by the said partition D into a receiving-compartment D and a counterweight-compartment Dfl'containingacoum tel-weight E, as plainly shown in Fig. 1. The port I) in the sleeve D leads to a passage or port 0, opening into the compartment D near the top of the partition D so that steam can Fig. 3 is a side pass from the sieam-inlet-O through the registering ports a, h, and 0 into the said compartment D to condense therein.
- The inner end ofv the water discharge or outlet 0 is adapted to connect by a port d in the wall of the pivot C with a port e, formed in the sleeve D and leading to a port f, extending upwardly in the partition D and from the upper end of this port f extends a pipe F, secured to the partition D and extending downwardly and forwardly in the compartment D to within a short distance of the bottom thereof at the outer end of the said compartment, as plainly indicated in Fig. 1. I
The ports a and dare so arranged (see Fig. 4) that when one is in register with its sleeveport 19 or c then the other port is cut 0E from its sleeve-port, and vice versa.
When the trap is emptied, as shown in Figs. 1, 2, and 3, then the counterweight E holds the vessel D normall in'a horizontal position with the compartment D resting on a set-screw G, carried by the stand A, and when the vessel is in this position the ports a and b are connected with each other, while the ports (1 and e are out of register. Now steam can pass from the steam-inlet O by way of the registering ports a, b, and a into the compartment D to fill the same with water of condensation, and when sufficient waterhas accumulated in the compartment to over balance the counterweight E then the vessel 'D rocks on its pivot 0 until the forward end of thecompartment D abuts against the setscrew G, carried by the stand A. '(See dotted lines, Fig. 3.) Now when this takesplace the port 6 becomes disconnected from the port a, While the port a moves in register with the port d, and consequently the water contained in the compartment D is now forced out of the latter by the pressure of the steam entrapped in this compartment through the pipe F, registering ports f,-e, and d, and water-outlet C to a suitable place of discharge. As soon as the water is discharged from the compartment D the vessel is caused to rock back to its normal position by the action of the counterweight E, and consequently the port a is again disconnected from the port d, while the port I) can move to register with the port a, and steam can now pass again into the compartment D and condense therein. The ports I) and 0 can be made to remain open or closed when the trap is discharging.
The above-described operation is then repeatedthat is, the vessel D is alternately rocked into a discharge position for discharging the water of condensation from the compartment D and into a receiving or horizontal position for the steam to pass into the said compartment to be condensed therein.
In order to prevent leakage, the vessel D is provided with suitable stuffing-boxes H, engaging the pivot G at the ends of the sleeve D, and in order to prevent lateral shifting of the vessel D on the pivot set-screws I are provided, screwing in the vessel through openings in the sleeve D to engage annular grooves O in the pivot O, as plainly shownin Fig. 4. Plugs J screw in the partition D from the top of the vessel into the ports cand f to allow of cleansing the same in caseit becomes necessary to do so.
From the foregoing it will be seen that the trap is completely automatic in its operation and is not liable to easily get out of order, as no valves, springs, or the like are employed.
Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. Asteam-trap, comprisingavesselhaving a partition for forming a receiving-compartment and a counterbalancing-compartment, a hollow pivot extending through said partition and provided with a steam-inlet and a water-outlet, and means for alternately connecting the receiving-compartment with the steam-inlet and the water-outlet, as set forth.
2. A steam-trap, comprising a support, a vessel having a transverse partition dividing said vessel into a receiving-compartment and a counterweight-compartment, the said partition being formed with ports communicating with the receiving-compartment, a sleeve secured in the transverse partition and provided with ports communicating with the ports in the partition, and a hollow pivot secured to the said support and extending through the said sleeve in the partition, the said pivot having a transverse partition at its middle to form a steam-inlet at one end of the pivot and a water-outlet at the other end, the said pivot havingv ports adapted to register alternately with the ports of the sleeve, as set forth.
3. A steam-trap provided with a counterbalanced vessel, a pivot for the vessel to turn on, from a receiving position into a discharge position and vice versa, thesaid pivot having an inlet for the steam and an outlet for the water, and the vessel being provided with a steam-inlet port and a water-outlet port, registering with the said steam -inlet and the said water-outlet in the pivot, a pipe extending into the vessel and connected with the water-outlet port, and means carried by the vessel and engaging the pivot to prevent lateral. shifting of the vessel on the pivot, as set forth.
4. A steam-trap provided with a vessel having a transverse partition for forming a receiving-compartment and a counterbalancing-compartment containing a weight, a fixed pivot extending through the said partition and provided with a steam-inlet and a wateroutlet, adapted to register alternately with ports formed in the said partition, the steaminlet port opening into the said vessel, and a pipe connected with the Water-outlet port and extending in an inclined position in the said receiving-compartment, as set forth.
5. A steam trap provided with a vessel having a transverse partition for forming a receiving-compartment and a counterbalancing-compartment containing a weight, a fixed pivot extending through the said partition and provided with a steam-inlet and a wateroutlet, adapted to register alternately with ports formed in the said partition, the steaminlet port opening into the said vessel, a pipe connected with the water-outlet port and extending in an inclined position in the said receiving-compartment, and means, substantially as described, for limiting the rocking motion of the said vessel, as set forth.
6. A steam trap provided with a vessel having a transverse partition for forming a receiving-compartment and a counterbalancing-compartment containing a weight, a fixed pivot extending through the said partition and provided with a steam-inlet and a waterontlet, adapted to register alternately with ports formed in the said partition, the steam inlet port extending into the said vessel, a pipe connected with the water-outlet port and extending in an inclined position in the said receiving-compartment, and means for holding the vessel against transverse movement on its pivot, as setforth.
