Application March 8, 1937, Serial No. 129.772 2 Claims. This invention relates to radiators for motor vehicles and more particularly to a ?lling device for the radiator and has for the primary object the provision of means whereby the greater pro5 portion of liquid directed into the radiator will be discharged into the lower chamber of said radiator to bring about ?lling of the radiator from the bottom upwardly to the top thereof so that the liquid will rise in the cooling jacket of 10 the engine to which the radiator is connected and thereby prevent trapping of air in the water jack et as now frequently occurs by the liquid ?owing into the return pipe of the radiator before the latter and the cooling jacket become ?lled with liquid. With these and other objects in View, this in vention consists in certain novel features of con struction, combination and arrangement of parts (Cl. 123-174) to the radiator and consists of a ?lling spout or neck 8 extending into the chamber 2 by being at tached to a wall of said chamber. The ?lling neck is normally closed by a removable cap or cover 9. The ?lling neck is integral with a pipe or tube It) extending downwardly into communicationwithv the lower chamber 3 so that when the liquid is poured into the neck it will be discharged into the lower chamber 3 and when ?lling the radiator and the cooling jacket of the engine the liquid 10 rises until the jacket is ?lled and the chamber 2, the latter receiving the liquid from the cooling jacket by way of the pipe 6. The radiator and cooling jacket ?lled in this manner will be free of air pockets. In order that a small amount of liq uid may pass directly into the upper chamber 2 small ports II are provided in the ?lling neck. However, the amount of liquid admitted directly to ‘ be hereinafter more fully described and 20 claimed. For a complete understanding of my inven to the chamber 2 will not be sufficient that it can— not be taken care of by the tubes of the radiator in passing in the direction of the lower chamber 3. tion, reference is to be had to the following de scription and accompanying drawing, in which Consequently, this liquid will not enter the pipe 6 and contact the thermostat which if engaged Figure 1 is a rear elevation, partly in section, by said liquid would assume a closed position and 25 illustrating a radiator constructed in accordance with my invention. Figure 2 is a top plan view illustrating the same connected to a water jacket of an engine and showing a thermostat associated therewith. Referring in detail to the drawing, the numeral 30 l indicates a conventional type of radiator em ployed on motor vehicles including the upper and lower chambers 2 and 3 connected by the cooling tubes 4 and on which. are mounted the ?ns 5 for 35 directing the air to the tubes. The character 6 indicates the return. pipe of the radiator while the character 1 indicates the outlet pipe. The pipes trap air in the upper part of the cooling jacket 25 and consequently prevent complete ?lling of the latter with the liquid. What is claimed is: l. The combination. of a radiator fashioned with upper and lower Water chambers, cooling 30 tubes connecting said chambers together, said upper and lower chambers having return and dis charge pipes respectively, said return pipe adapted for connection with a return line having a ther mostat therein for controlling the ?ow of water ' therethrough from the water jacket of an engine, said discharge pipe adapted for connection with 6 and l are connected through return and feed a feed line to said jacket; and a quick ?lling de lines 6a and ‘la. respectively to the cooling jacket vice for ?lling said tubes and comprising a ?lling neck extending through said upper chamber and communicating with said lower chamber, said neck fashioned with outlet ports within said up per chamber to permit a ?lling of said tubes from said upper chamber coincident with the ?lling of said tubes from said lower chamber, said ports 40 l5 of the engine of the motor vehicle. In the, re turn line 6a, between the cooling jacket of the engine and the return pipe 6, there is located a thermostat l6 for the purpose of controlling the circulation of the Water through the jacket from 45 the radiator. Radiators and cooling systems of engines equipped with a thermostat as referred to require very slow ?lling of the system with liq uid or otherwise air will become trapped in the upper portion of the water jacket or between the ~50 latter and the upper chamber 2 of the radiator so that if unnoticed will bring about overheating of the engine for lack of liquid. To prevent the for mation of air chambers in the cooling system as above stated and to permit the radiator to be 55 rapidly ?lled with liquid my invention is adapted of a size relative to said tubes to preclude water discharging therethrough from ?ooding said up per chamber and consequent over?owing into said return line in advance of the ?lling of said tubes whereby to prevent actuation of said thermostat to closed position before water from said lower chamber in?uences such actuation thereby elimi nating the formation of air pockets in said jacket and return line. 2. The combination of a radiator fashioned 55 2 2,128,696 with upper and lower Water chambers, cooling tubes connecting said chambers together, said up per and. lower chambers having return and dis charge pipes respectively, a water jacket of an engine having return and feed lines connected to said return and discharge pipes respectively, a thermostat Within said return line for controlling the ?ow of Water therethrough from said water jacket, and a quick ?lling device for ?lling said 10 tubes and comprising a ?lling neck extending through said upper chamber and. communicating with said lower chamber to permit a ?lling of said tubes from said lower chamber to preclude wa ter from ?ooding said upper chamber and over ?owing into said return line in advance of the ?lling of said tubes whereby to prevent actuation of said thermostat to‘closed position before water from said lower chamber in?uences such actua tion thereby eliminating the formation of air pockets in said jacket and return line.
