Specification of Letters Patent. l

Patented Feb. 28, 1911.

Application filed October 24, 1906. Serial No. 340,421.

To all wkmn it may co'rwcrn:

Be it known that I, AxEL VALDEMAR CLomUs, a subject of theKing of Denmark, residing at Copenhagen, Denmark, have invented certain new and useful Improvements in Valves, of which the following is a full, clear, and exact description.

The present invention relates to valve mechanism, and more particularly'tothose in which the valve is automatically operated by thermo sensitive devices, the object of the invention being to provide a simple, economical, compact and eflective'device in whichinjury to the parts is prevented when, after the valve has become seated, the temperature acting on the thermo-sensitive device continues to increase; and to provide a seat-valve which will be cheap, simple and effective in operation. Briefly stated,:these objects are attained by providing a coneshaped valve adapted to seat againsta partition in the valve casing, a resilient body being interposed between the valve and the thermo-sensitive device, which resilient body is compressed when, after'the valve is seated, further movement of the thermo-"sensitive device or a part thereof is had.

The invention will be better understood by reference to the accompanying drawing, illustrating a'vertical section through the mechanism, and w erein a is a valve casing provided with a perforated partition 8. Ar ranged in line with the perforation in said partition is an elongated tubular extension is secured at one end in a perforated nut m, screwed into said casing a, and at its other end to a member I. Arranged within said extension is is a valve-stem d one end of which engages in a perforation invalve b which is adapted to obturate the perforation in partition .9. A resilient body, here shown as a coiled spring 0, encircles said valve-stem and bears against valve 6. The lower end of the valve stem 1 is secured to one end of a suitable thermo-sensitive device. As here shown, said stem at is connected to one end of a rubber tube h, the otherend of which tube is immovably connected to a perforated block a which extends intosaid extension k. A chamber -e, arranged in the room or fluid the temperature of which isto be regulated, contains any suitable fluid which will expand under the influence of heat, and a conduit 9 connects this chamber with the interior of the tube It via the perforation in block a. A series of metallic rings 7' encircles said tube It to preventlateral "expansion thereof. When, therefore, the fluid in chamber 6 is caused to expand under the influence of heat, the tube It is caused to elongate and to seat valve 6 against partition s. Should the tempera ture still increase the continued elongation of the tube It would result in the compression of spring a, the valve being thus pressed somewhat more firmly on its seat, without, however, damaging the device. A decrease in temperature will result in the'contraction of said tube h, an expansion of spring 0 and seated thereon, an elastic tube adapted to confine a fluid subject to variations of pressure, non-yielding rings surrounding said tube for restricting the expansion of the latter in a longitudinal direction, resilient means for transmitting the longitudinal movement of said tube to said valve to operate the latter in response to variations of said fluid pressure and a tubular extension for inclosing said valve operating means, and a stufiing box on said extension having an adjustable plug to which said flexible tube is secured whereby said movable parts may be adjusted.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
