ROBERT WILKINSON NEWT0N,10F PROVIDENCE, RHODE ISLAND.
AUTOMATIC SPRINXII'ER.
To all whom 'it may concer/n.:
Be it known that I, ROBERT WILKINSON NEWTON, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Automatic Sprinklers, of which the followis a specification. y inventlon has reference to an 1mprovement 1n automat1c sprinklers and more particularly to an improvement in automatic sprinklerscas shown in United States Patent No. 1,392,593, granted to me October 4, 1921.
The object of my invention isto improve the construction of the valve support .and releasing device of automatic sprinklers.
A further object of my invention is to improve the construction of the valve support and releasing device comprising a reversible thermometer in strut formation, whereby the automatic sprinkler may be used in either a vertical or pendent position.
My invention consists in the peculiar and novel construction of automatic sprinklers and more particularly `to an improvement in the construction of the valve support and releasing device of automatic sprinklers, said Avalve support and releasing device comprising a reversible thermometer in strut formation and details of construction, as will be more fully set forth hereinafter and claimed.
Figure 1 is a front view of my improved sprinkler.
Figure 2 is a sectional view taken on line 2, 2 of Figure 1.
Figure 3 is an enlarged front view of the valve support and releasing device. l l
Figure 4 is a still further enlarged longitudinal sectional view through one end portion of the valve support and releasing device, the other end portion being broken away, and
Figure 5 is an enlarged view of the end of one of the wires showing the filament lon the end of the wire.
In the drawings 6 indicates an automatic l sprinkler body and 7 my improved reversible support and releasing. device in the form of a reversible thermometer, -in strut formation.
Application led December 19 19,21. Serial No. 523,494.
in Figure 1. f A valve head 13 in the form of a cover .normally closes avalve seat 14, the valve head 13 having a central raised'tet 15 and the screw 11 having a cone shaped inner end 16, as shown in Figure 2. Th'e valve head .13 also hasa packing 17 and a cone shaped spiral spring 18, shown in the contracted position. f
My improved reversible valve support and releasing device '.7 is in the form of a reversible thermometer in strutV formation and consists of a break'able reversible thermometer 19 preferably of glass and having comparatively strong tubular ends 20, 20 and an enlarged central bulb '21. Each end is closed by a cap 22 having a central depression 23 and a packing 24. Extending at an angle in each end portion into the bulb 21 is a wire 25 having on its inner end a piece of filament 26 the same as used in incandescent lamps. Each wire 25 extends through a screw-threaded fitting 27 cast into the thermometer, ya cap 28 is secured over the iting and a set screw 29 is screw-threaded through the cap 28 onto the wire25 and solder 30 is placed inthe cap 28. After the wires 25, 25 are adjusted to any degree of temperature desired, indicated by thermometer scales 31, 31, the set screws 29, 29 are tightened against the Wires and the solder melted, thereby sealing the wires in the adjusted positions. `Thewires 25, -25
are connected to a source of electrical energy,
not shown. The tet 1'5 on` the valve head 13 l enters the depression 23 inthe cap 22. at one vconditions and the heat of theA ire has reached say 140 degrees at the sprinkler, the li uid v33 rising on topof the mercury 32 will touch the upper filament 26, thereby closing the circuit and causing the filament 26 to glow or to have sufficient heat lto 1nstan-tly expand or explode the liquid 33, which mayl be of any substance for this purpose, thereby destroying .the thermometer releasing device, releaslng the valve head 13 and causing the sprinkler to open instantly Aat 140 degrees of temperature. By varying the position of the ends of the wires 25, 25 in the thermometer, theformin sprinkler may be caused to open instantly at any degrees of temperature desired.
It is evident that the Wires Q5, 25 could be used Without the filament-s 26, 26 if desired, as an arc would form causing a spark just before the liquid would touch the, end of the upper wire, also the Wires and electric system could be dispensed With in which case the expansion of" the mercury and liquid would burst the thermometer at a given temperature.
Having thus described my invention I claim as new l. An 'automatic sprinkler having incorporated therein a reversible thermometer one of the controlling elements of the sprmkler, for the purpose as, described.
2. The combination with an automatic sprinkler of a reversible thermometer in strut formation and interposed intermediate the valve seat and the frame hub of theP sprinkler.
3. The combination with an automatic sprinkler of a reversible thermometer in strut formation and interposed between the valve head and the frame hub of the sprinkler and an adjustable electric attachment on the reversible thermometer strut forma-tion.
4. The combination with an automatic sprinkler of a holder of glass or other breakable material, an expansible material in said holder, said holder being in the form xbreakable material,
of a strut intermediate the valve seat and the frame hub of the-sprinkler.
5. The combination with an automatiq sprinkler of a holder of glass or other* said holder having tubular ends and a central bulb, of mercury in the tubular holder, of a liquid in the tubular holder, said tubular holder being in the form of a strut intermediate the valve seat and the frame hub of the sprinkler. j
6. In an automatic sprinkler a holder of glass or other breakable material, said holder having tubular ends, a central bulb, means for closing the tubular ends, an expansiblevmaterial lin the tubular holder, ad-
justable wires extending into the tubular holder, means for adjusting the Wires and means for sealing the Wires in the adjusted position, for the purpose, as described.
7. In an automatic sprinkler a holder of glass or other breakable material, said holder having tubular`ends, a central bulb,
means for closing the tubular ends, an eX- pansible material in the tubular holder, adjustable Wires extending into the tubular holder, means for adjusting the Wires, means for sealing the Wires in the adjusted position, and scales on the tubular holder,
for the purpose, as described.
In testimony whereof, I have signed my name to this specification.
ROBERT WILKINSON NEWTON.
