SUPERHEATEB.

Specification of Letters Patent.

Patented May 18, 1909*.

Application filed December 20, 1907. Serial No. 407,316.

To o!! l'whom 'it may concern:

Be it known that I, SAMUEL M. VAuoLAln, a citizen oi' the United States, residing in Philadelphia Pennsylvania, have invented certain Improvements in Suierheaters, ol which the following is a speci 'ic-ation.

My invention relates to certain improvements in locomotive boilers in which the supcrh'eatcr is located in the smoke box, and

y which is connected to the boiler and to the cylinders ol' the locomotive.

'lhe object ol my invention is to so com struct a superheater that the steam will en ter the endof the superheater farthest from the boiler, and will be discharged from the superheater at a point near the boiler.

In the accompanying drawings: Figure 1,r is a longitudinal sectional view on the line l-l, Fig. 2; of my improved superheater; Fig. 2, is a transverse scr-.tional view on the line 2 2, Fig. 1, the nozzle being in elevation; Fig. 3, is a plan View of the top plate of the superhea'ter; Fig. 4, is a longitudinal section on'. the line 4 4, Fig. 2; Figs. 5 and 6, are

views of modifications ol my in yention g andv Fig. 7, is a view of the deflecting plate.

A is the locomotivelboiler having tubes a, which are secured to a tube sheet a in the `ordinary manner.

A is the smoke box casing inclosing the vsup-,rheater made in two parts B, B', as shown clearly in Fig. 2. Within the smoke b'ox is the nozzle c, the hood c', and the stack C, of the usual construction.

The superheater in the present instance is made in two sections, as shown, each section havingI an upper header I), a lower header D', and connecting tubes d. These tubes are bent so v4as to conform to the shape of thc shell of the superheater as near as possible. This construction enables me to place the superheaters in each side of the smoke box, leaving the central portion clear and unobstructed, so that access may be had to the interior of the smoke box.

The header D consists of a casting d and the tube plate d2. 'llhe casting d in the present instance, ,has a longitudinal partition d3, and two transverse partitions (Z4, as shown by dotted li-nes in Fig. 3, which separate the header I) into sections. 'lhe tube plate cl2 is connected to the casting d, by bolts e. In some instances, the center line of bolts which pass through thepartition da may be dispensed with.

E is a tubular enlargement forni-ing an integralpart of the casting d", and extends nearly the full length of the header l), as indicated in Figs. 1 and 4. This tubular eXtension 'connects with the forward end ol the header through a passage e, and is coupled at the opposite end to a T-union Fwhic 1 in turn is-coupled to the tube F leading to the steam space in the boiler.

'lhe lower header D consists in the. present instance of a body portion g, a tube platej" coupled to the castiner by oltsg, and this header has a series ol? partitions dividing it into sections, and'has a neckf communicating with the steam supply lpassage G of the steam cylinder. 'Ihepartitions are so arranged as shown in Figs. l and 3, that the 'circulation ol' the steam through each superheater section is l'roln the boiler, into the p'assage c direct to the forward end ol the header l), then down the tube 1, returning through the tubes 2, then down through tubes 3, returning through the tubes 4, passing down the tubes 5 to the outlet end of the su erheater, which is connected through a nec if to the passage G, leading to the cylinders.

It will be noticed that the construction of the superheater section B is similar to the section B, and is coupled in the same manner to the union F, and to the passage in the cylinder castmg G. y

I,` I are two dellecting plates, one on each side of the center of the smoke box, and these i dellecting -plates are drawn together at the supply pipe E formedintegralvwith the castmg of the upper header D, 'fbut it will be understood that a pipe, asshown at E, Figs. 5 and G, may be use( if ,lesired,-a pipe E being coupled to nach side of the union F, and

coupled to the forward end of the super- 4heater, as shown.

I claim: The combination of a superheater adapted l-lO to be mounted in the smoke box of e loeomol pipe leading from the boiler, substantially es 10 tive boiler, consisting of upper and lower described, headers and connecting tubes, the upper In testimony whereof, I have signed my header having a tube plete and a recessed name to this specification, in the presence of casting having integral partitions, and havtwo subscribing Witnesses.
