' METALLIC Ennmron THEBMOMETER.
Application filed August 8, 1922. Serial No. 580,490.
To all whom it may concern:
Be it known that I, RICHARD G. HEBROCK, a citizen of the United States, residing at Irvington, in the county of Essex'and State of New Jersey, have invented certain new and useful Improvements in Metallic Radiator Thermometers, of which the following is a specification.
My invention relates to improvements in the metallic radiator thermometer for which Letters Patent No. 1,420,038 were granted me on June 20, 1922. The object of the invention is to improve the thermometer shown in my patent above referred to by mounting the thermostatic spring in the lower end of the depending nipple of the thermometer casing, where it will be more readily influenced by the rising temperature of the water in the radiator and in connecting the free end of the spring with a pivoted shaft mounted in the said casing and carrying the pointers.
This object I accomplish by the construction shown in the accompanying drawing, in which:
Fig. 1 is a front elevation of my improved thermometer.
Fig. 2 is a rear elevation partly in section.
Fig. 3 is a section on line 3-3, Fig. 2. -Fig. 4 is an enlarged sectional elevation of the thermostatic spring an connected parts removed from the casing.
Fig; 5 is a detail sectional view, showing the spring and its cup-like support. The circular casing 1 of the thermometer has an internal annular flange 2 and a depending hollow threaded attaching nipple 3 adapted to be secured to a radiator cap as in my said patent, while across the lowerportion of the casing extends a bridge formed of parallel centrally apertured spaced bars 4-4 secured at their ends to the flange 2. The dial 5 is formedof two separate plates 6 graduated from O to 300.
Within the lower end of the tubular nipple or extension 3 is a close fitting cup-like stopper 7 within which is secured the base 11 of the coiled thermostatic spring 10 of the patcut referred to. This base 11 is provided, as before, with the slot 12 to afl'ord two points of attachmentto the cup-like stopper 7 and this slot permits the spring to have its narrower coiled portion to pass there through so that it will lie in the same plane with the free end 13. This free end 13 has a cross piece 9 to which is loosely connected an eye formed on the lower end of a connecting rod 8, the upper end of which is loosely connected to a crank arm 15 project C9 ing from the middle of a pointer shaft 16 mounted at its ends in the bridge bars 1-4; above described. The pointers 14: are respectively secured to the ends of the crank shaft 16 adjacent to the graduated faces of (35 the dials. The lower edges of the dials do not. require cutting away as in my patent. but are merely apertured for the passage of the ends of shaft 16.
The casing 1 is closed by means of glass 769 disks 17 17 held in place by the outer rings 18, 1-8 and the screws 19 which engage threaded apertures in the flange 2 just as in my said patent. The washers 20 are also employed between the glass disks and the flange 2.
In assembling the parts the cup-like stopper 7 will be moved up or down in the lower end of the extension 3 until the pointers 1 1 register properly with the 0 graduations, $9 whereupon the stopper 7 will be firmly fixed in place bysoldering or otherwise. The thermostatic spring 10 being located in the lower end of nipple 3 will be more quickly influenced by a rise in the temperature within the radiator and will not be subjected to the changes in temperature exterior to the radiator. Furthermore, vibrations of the machine will not be so readily transmitted to the pointers where the connecting rod of the present construction is employed as would be the case where the pointers are .directly connected to the ,free end of the spring.
What I claim is:
1. A metallic radiator thermometer comprising, a casing having a dial formed of two separate plates and provided with adepending tubular attaching nipple opening at its upper end thereinto and closed at its lower end, a coiled thermostatic spring se-' cured at one end in the lower closed end of said nipple, a rock shaft mounted in the casing and provided with pointers at its ends for said dial plates, and a connecting rod operatively connecting the said rock shaft with the free end of said thermostatic spring.
2. A metallic radiator thermometer comprising, a. casing having e dial formed of two per closingthe lower end of theettaching separate plates and provided with a dependnipple, and a thermostatic convolutespring 10 ing tubular attaching nipple opening at its secured at one end Within the cup vand conupper end thereinto, a rock shaft mounted nected at its free end to the l Wer end of in the casing and provided at its ends with the said connecting rod.
