IMPROVEMENT IN STEAM-TRAPS.

Specification forming part of Letters Patent No. 43,090, dated .I une 14, 1864.

To all whom it may concern:

Be it known that I, CHARLES H. BROWN, a resident of Fitchburg, in the county of Worcester and State of Massachusetts, have invented au Improved Steam-Trap; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a side elevation, Fig. 2 a top view, and Fig. 3 alongitudinal section, of it.

When steam is employed in pipes or drums for heating them for the purpose of warming the atmosphere of a room or apartment, more or less condensation of the steam within the pipe or drum will taire place.

The object of my invention is to discharge from such a heating pipe or pipes or drum the water which may be so produced thereinviz., by the condensation of the vapor or steamthe discharge of such water being effected without any material loss of steam.

While in operation the trap is to be so arranged with respect to and connected .with the heating pipe, pipes, or coil, or steamdrum, as the case may be, as to enable the condensed water thereof to How freely into the expansiontube of the trap and out of its valve-opening.

In the drawings, A denotes a tube ot' metal provided with a tubular elbow, B, at one end and an arm, C, projecting from its opposite end.

Within the elbow B is a partition, I), which extends across the interior of the elbow, and is provided with a valve-opening, a, in manner as represented in Fig. 3. The lower part of the elbow is open as shown atb. Avalve, cfis applied to the opening a, the. stem d, of the valve being extended laterally through and out of the elbow, and being straddled by a bifurcated lever, D. Where the said lever embraces the valvestem such lever is arranged between two shoulders, e'f, formed on the valve-stem and close to the lever. The said lever D has its fulcrum g at or near its upper end, and supported by an arm, E, projecting from the elbow B, in manner as shown in the drawings. A rod, F, connected at one end to the arm C, encompasses at its opposite end the lever D, or may be jointed to it just below its fulcrum. If we now suppose the tube r A to be secured to the lower part of the steam heatingpipe, coil, or heater, as the case may be, and so that the condensed water thereof may ow immediately into the said tube A, the operation of the apparatus may be thus described: So long as there may be steam within the tube A, such tube will be expanded by the heat of such steam and by means of the arm E will so force the lever D' against the rod F as to cause the said lever to be moved in a manner to press the valve c t'oward its seat s, and close the opening a, such seat at the same time being by the expansion ot' the tube moved toward the valve; but when there may be a condensation of steam within the tube A to such an extent as to cause the tube to be contracted lengthwise, the valveseat and the valve will be moved simultaneously away from one another so as to open the valve, in which case the water of condensation will be expelled through the valve-opening a and discharged through the opening b.

I claim- My improved steam-trap, having' its single expansion-tube A, the valve-opening a, the valve c, the valve-lever D', the arm or fulcruin supporter E, and the lever-operating rod F, arranged and applied together, substantially in manner and so as to operate as specified.

CHARLES H. BROWN.
