Letters Patent o. 96,541, dated November 9, 1869.

STEAM-TRAP.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, SAMUEL BoNsER, of Dover, in the county of Strabrihand State of New Hampshire, haveinvented anewand useful Improvement in Steam- Trap; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. 4

This invention relates to a device for discharging the water of' condensation from a steam-heating or other steam-apparatus, and consists in the arrangement hereinafter described.

In the accompanying plate of drawing- Figure 1 represents a vertical section of the trap, through the line x x of Iig. 2.

Figure 2 is a horizontal section, through the line y y of g. 1.

Similar letters of reference indicate corresponding parts.

A is a vtriangular head at the top of the instrument.

B is a similar triangular plate, which is screwed to the cylinder C by the nut c'.

These triangular plates are securely held together by means of the three rods 1),-which have screw-nuts ateach of their ends, as seen in the drawing.

E is a tube within the cylinder C; and secured to the tube E is another tube, F, which is screwed into the triangular head-piece A. 'Ihese tubes are made of copper or other suitable metal.

On the lower end ofthe cylinder G there is a thimble'nut, G, which holds, within the'lower part of the cylinder, the tubular spindle H.

The upper end of this tubular spindle, and thelower end of the tube E, are square, flat surfaces, forming a joint, J, surrounded bythe chamber I, which chamber is in communication 'with the outlet-pipe lt.

The water of condensation enters the tubes E and F, and is discharged, between vthe ends oi' the tube and the spindle, into the chamber I, and from the pipe K.

When the waterI has been thus discharged, and steam enters and takes its place, the tubes E and F will expand downward from the head-pipe A, in length, suiiciently to close the aperture or jointl J. Then water again accumulates and becomes cold, those tubes, or one of them, contracts, and the water is again discharged, and so on indefinitely.

The thiinble-nut G: allows the tubular spindle H vto be adj usted with the greatest nicety, so that the joint J will close when the tube contains steannand open when itcontains water, or when the temperature fails.

It will thus be seen that the temperature governs the operation of the instrument with perfect precision when it is properly adjusted The operation will be the same if the steam only enters the tube F, but thc longer the tube is exposed to the variations of temperature, the more will be the expansion and contraction. v

I am aware that a patent was granted, J nly 7,1863, for a steam-trap, exhibiting some similarity of construction to mine, but I desire to disclaim any and all peculiaritiea thereinv shown.

Hating thus described my invention,

I claim as new, anddesire to secure by Letters Patent-f The arrangement of the tubes E E, andthe tubular spindle H, in combination with the cylinder Gr, trianguiar pins A and B, and the rods D, substantially as and for the purposes described.
