Intro Enema- Awlhuflnn filed April 19, 1918. Serial No. 229,581:
' mounting the. temperature responsive elements of indicating instruments or other devices in ducts and'more particularly in the iping of engine cooling systems. In my atent No. 1,206,783 I have disclosed an invention relating to the indication of the condition of internal combustion engines of vehicles, said invention being characterized by the introduction into the engine cooling system, at a point where the cooling water has been heated by contact with the engine cylinders, of a temperature responsive element controlling indicating device readable by the driver. A preferred location for such temperature responsive element, as illustrated in said patent,'is in the return pipe leading the heated cooling water from the cylinder jackets to the adiator. present invention is especially adapted to provide means for mounting a temperature responsive element in this location although the invention be utilized in any analo us situation.
n the accompanying drawings which form a part of this specification Figure 1 is a diagrammatic side elevation illustrating the engine and cooling system of an auto-' mobile, aeroplane or other vehicle and showing a preferred application of the invention,
thereto.
Figure 2 is a longitudinal, sectional view, of a duct section having a temperatpre responsive element introduced there nto in accordance with the invention.
Figure 3 is an end view ting with a bulb therein.
Fi re 4: is a horizontal section on line IV--- V of Figure 3. Figure 5 is a vertical section on line V-V of Fi ure 2.
Re erring to the drawings in detail, I have illustrated in Figure 1 the application of the invention to the return pipe. of a vehicle engine cooling system. The numeral 1 des-' ignates the engine which has c linders 2 surrounded b a water-jacket 3. he water is cooled in the radiator'et which may be of any usual or well known construction. The cooled water p'assesfrom the radiator to the jackets through an i let pipe 5 which may .be provided, as is cus tbma'ry, with a flexible pipe section 6 so as to permit the slight relative movement caused by the vibration of the parts to take place wlthout injuring the radiator or loosening the joints of the piping. A'pump 7 ma 7 beprovided for causing the forced 'cireu atidn of the Water, although as will be understood the invention is equally applicable to a thermo-siphon coolin system in which no pump is employe The heated Water from the jacket 3 returns to the radiator through a return pipe section 8 connected to the engine, the pipe section 9 connected to the upper 'part of the radiator, and the connections between these pipe sections to' be described.
In vehicle engine cooling systems it is customary to connect the pipe sections 8 and '9 with a flexible section, usually of rubber hose, and similar to the flexible section 6 shown in theinlet pipe. In accordance with Y my present invention I take advantage of the presence of this flexible section to pro-- any machine work upon the engine or cool- .ing system or drilling any holes'in the metal parts of the system. I accomplish this result by cutting out a portion of the flexible pipe section and introducing a fitting carrying the temperature responsive or other element. As specifically illustrated in the drawings I provide a fitting 10 having nipple portions 11 and 12 of substantially the same diameters as the diameters of the adjacent return pipe sections 8 and 9 respectively, and connect these-nipple portions to the return pipe sections by short hose sections 13 and 14. The ends of these hose sections may be secured to the pipe sections and nipples in any desired manner, preferabl by the use of hose'clamps 15 of any suitable construction. The hose clamps illustrated comprise metal strips bent to enclose the hose and having outwardly turned may be cut or removed Without difliculty.
to compress the overlapping portions of the hose section tightly upon the nipples or plpe sections within them. In this way it will be seen that the fitting 10 is permanently and tightly introduced into the cool ng system and forms a part of the ductthrough which the cooling liquid flows; this result being accomplished without disturbing any part of. the cooling system except the flexible hose sectionconnecting the parts 8 and 9-, which -ment or distance type thermometer is provided having an indicating gage mounted i seriously impede such flow provided the on the vehicle dash 21 or in any other suitable location, the gage'being connected by a capillary tube 22 with a temperature responsive element in the form of a fluidfilled bulb 23. The fitting 10 is in this instance formed to provide a seat for holding this bulb in the path of the cooling liquid passing through the return pipe. For this purpose the fitting is provided with an enlarged chamber 24 between the nipples 11 and 12, this chamber having an opening 25 at one side thereof and the fitting being formed with a seat 26 around this openingvand with a neck 27, the latter being preferably threaded as at 28. The bulb 23 is passed through the opening 25 into the chamber 24, across which it extends diametrically. The bulb is also provided with a flange 29 which is received within the neck 27 and is supported upon the seat 26. Suitable packings 30 and 31 may be introduced above and below the flange if desired. A gland 32- h aving an opening 33 for the capillary tube 26 is screwed into the threaded part of the neck and compresses the -packings,30 and 31' upon the flange 29 and against the seat 26,-thereby holding .the bulb firmly in position and efi'ectually preventing leakage. The provision of the enlarged chamber 24 to receive the bulb is' a valuable feature as it permits the free flow of the cooling liquid through the return pipe. If the enlargement were not presence of the bulb 23 would, i n cases where the'capacity of the return pipe was only just suflicient to take care of the maximum flow of the cooling liquid, and interfere with the Such a result would be most objectionable as it is well known that insufficient cooling will permit the engine to overheat with results which may be disastrous.
While I have illustrated and described in detail one'preferred form and application of my invention it .will be understood that the invention may be modified in va- -properjcooling of the engine;
rious ways and I do not therefore wish to be limited to the particular construction shown but intend to cover my invention broadly in whatever form its principle may be embodied.
Having thus described my invention I claim; e
