I STEAM H EATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 499,231, dated June 13, 1893.

Application filed August 13, 1892. Serial :Nm-143,029. (No model.)

.To all whom it may concern.-

Beit known that I, FRITZ KAEFERLE, a subj'ect of the King of Wiirtemburg, and a resident of Hanover, Germany, have invented a new and useful Improvement in Steam Heating Apparatus, of which' the following is a full, clear, and exact specification.

In order to regulate accurately and quickly asteam heater, it is necessary to allow the hot steam free access and in any desired quantity, and to permit the Water of condensation to I'low oiI as soon as formed without interfering with the entrance of the steam, and at the same time preventing absorption of the heat by the accumulated water. Iaim in this manner to overcome the shocks so noticeable in steam heaters by providing for the inlet of the steam and exit of the water of condensation through the same pipe, but-without the slightest interference.

In the accompanying drawings; Figure 1 shows a sectional view of part of a steam heater with my regulating apparatus annexed to it. Fig. 2 is an end View of Fig. 1 partly in section. Fig. 3 is a side elevation of part of a heater similar to Fig. l. Fig. 4 is an end 'view of Fig. 3 with the regulating means in section. Figs. 5 and 6 represent a longitudinal and a vertical section of a regulating apparatus of a modified construction.

a, represents a hollow body placed lengthwise within a casing b which also serves to support the heater or as a base therefor. This pipe or tube a is in connection at one end with the steam conducting pipe c and at the other end with the heater D. The hollow body and .the bearing therefor within the case which can be either of cylindrical or of conical shape, are provided with two corresponding openi-ngs d and e, of which cl is located on the top and e at the bottom, which openings form a connection between the conducting pipe c and the heater D. Thecase h is further provided with a short pipe f which projects into the inner part of the heater D and is intended to provide a passage for the steam independent of the exit for the condensed water which flows from "the heater through a passage formed around the pipe f leading to the case b and from thence the water of condensation flows through the openinge to the conducting pipe o, so that a crossing of the hot steam with the condensed water is prevented and consequently also the vstriking and the shocks in the heating apparatus. If the heater' works always under a low pressure of steam and the steam penetrates into the heater without much tension,-

the pipe f can be omitted without affecting the silent operation of the apparatus. If on the contrary the heater works with a high pressure the pipe f must be used, because in that case, the steam which rushes in under a high tension will try to push back and drag 'along the outflowing water, and will then occasion the striking and the shocks.

The steam used for the heating of the apparatus D penetrates into the hollow body a through they pipe c and from there into the inner part of the heater itself through the top opening d, where it communicates its heat to the walls of the same. The condensed water gathers in the lower part of the heaterD and of thecase b,"passing off through the lower opening e of the body a to the pipe c and thence to' the boiler, or to a tank built for that purpose. By turning the hollow body a along its longitudinal axle, the openings d and c wherewith it is provided come into a different position in regard to the corresponding openings in the case b, vby which the apertures through which the steam passes can be made larger or smaller in' order to regulate the same. This bringing in motion of the hollow body can be caused by an endless worm g with a handle which engages teeth on the periphery of lthe body or. A screw c' in the case b limits the movement of the hollow body a.

In Figs. 5 and 6 a slight change is made over the construction shown in Figs. l to 4. In Figs. 5 and 6 the body extends to the rear of the casing b and has direct communication with the pipe f and the worm and gear for rotating it are at the extreme end.

In combination with a steam heater, an outlet pipe c, a pipe f, for delivering the steam to the heater, a revoluble body c ining an opening for the outiow of said Water, aelrposed between thez inlet pipe c, and pipe Substantially as described.
