AUXILIARY APPARATUS FOR COOLING SYSTEMS.

Application led January. 12, 1922. Serial No. 528,659.

To @ZZ 'whom t may concern Be it knownthat I, INILLIAM R. SMITH, a citizen ofthe United States, Aresiding at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Auxiliary Apparatus for Cooling Systems, of which the following is a specification.

My invention relates 't0 cooling systems for automobile internal combustion engines, and the purpose of my Ainvention is the provision of an apparatus kadapted for association with any cooling system of standard construction which operates to collect all water and steam ordinarily expelled from the radiator and to cool the water so collected and return the same to the cooling system whereby, the cooling eiiiciency of the steam is greatly increased and lwithout the loss of water.

It is also a purpose of my invention to provide a cooling apparatus whichv can be employed to effect an injection of water from an exterior source into the system and in such manner as to eliminate the necessity of removing the radiator cap.

I will describe one form of apparatus embodying my invention and will then point out the novel `features thereof in claims.

In theaccompanying drawings,

Figure 1 isa view showing in side elevation a cooling system for automobile engines having applied thereto one form of apparatus embodying my invention.

Figure'2 is an enlarged detail sectional view showing the condensing tank comprised in the apparatus lshown in Figure 1.

Figure 3 'is a top plan view of the tank shown in Figure 2.

Figure 4 is a fragmentary sectional view of the tank shownin AFigure 2.

Figure 5 isa detail view partly in Vsection showing one form of water level indicator embodying my invention and comprised in the apparatus shown in Figure 1.

Similar reference characters'refer to similar parts'in each of the vseveral views.

Referring specifically to the drawings and particularly to Figure 1, my invention in its present embodiment comprises a water collecting 4and steam condensing tank designated generally at T, and which is adapted to be supported at the forward end 'of an internal combustion engine shown Vdiagrammatic'ally and indicated at E in Figure 1, by means of a bracket B so as to rigidly support the tank between a radiator It and -the engine E. The upper end of the ltank Tis provided with a cover 15 formed with a suitable opening to receive a short section of pipe 16 connected to a union 17, with the latter in turn in communication with a flexible pipe 18. The upper end of the l,latter is connected to the radiator R ata point adjacent its upper end as indicated at. 19 so that excess water and steam from the radiator can pass downwardly through the

pipes

18 and 16 into the tank T. The water and steam entering the tank T pass into a tubular member 2O having itslower end open and provided with perforations 21 adjacent the lower end and through which water passes into the tank at a point iadjacent the bottom thereof. The lower end of the tank T is adapted to communicate with a pipe `P constituting a part of the usual cooling system for an internal combustion engine, through a pipe 22 connected at its upper end to a T 23, with the latter in turn connected to a short section of pipe 24 which communicates with the lower end of the tank T. The T 23 carries a petcock 25 by means of which the tank can be drained from time to time to effect removal of sediment and other foreign matter. The lower end of the pipe 22 is connected to the pipe P as clearly shown in Figure 1, and in the vertical portion of the pipe 22 a valve 26 isprovided having an operating arm 27 connected thereto for effecting a closing or opening of the valve'to connect or disconnect the tank T from the pipe I). To effect a manual operation-of the valve 26, a flexible cable 28 is connected at one end to the free `end of the arm 27, and at its opposite end to a handle or button 29 disposed on the instrument board 'of an automobile and in convenient position to allow the manual operation thereof in eifecting actuationof the arm 27. The spring 30 is connected to the free end of the arm 27 and to a split ring 31 embracing the pipe P, this spring serving to normally urge the arm 27 to a position in which the valve 26 is closed. The operation of the cable 28 will therefore be in opposition to the spring 30 so that when the valve 26 is moved to open position by pulling on the button 29, the spring 30 will operate to close the valve when the button is released.

As in the usual cooling system for internal combustion engines, the pipe P serves to connect the radiator R `with* a pump M,

the latter serving to constantly circulate the water through the cooling system. In conjunction with the usual cooling system a fan F is employed directly behind the radiator R, and by consideration of Figure 1v it will be clear that the arrangement of the tank T is such that it is disposed lrearwardly of the fan F so as to be within the draft of air created by the fan rearwardly through the radiator.

Referring to Figure 2, theftank T contains an indicator for indicating the amount of water contained within the tank. This indicator in the present instance comprises a rod 32 t0 the lower end of which is sccured a float 33, while its upper end is provided with a plug 34 threadedly tted within a collar 35 secured to the top 15. The upper end of the rod 32A extends through a suitable opening formed within the cover 15 so that when the plug 34 is disengaged from the collarl 35, the float 33 will be free to movethe rod vertically so as to indicate the exact level of water within the tank.

To allow of an overflow from the tank T should it become completely filled with water, 1an overflow pipe 36 is provided which, as Vshown in Figure 2, is extended vertically within the tank with its lower end secured within the bottom of the tank as shown. ltsI upper end carries a cap 37 of-tubular form and which is secured to the pipe so as to provide a passage-way 38 through whichthe water passes in entering the upper end of the pipe. The upper end of the cap 37 is perforated as shown to prevent the forming of a Siphon in the pipe and cap/'For the purpose of preventing splashing and undue movement of the water within the tank a float 39 is arranged within the tank in the manner shown 'in Figure 2, with the float formed with suitable openings to allow of its unrestricted movement with respect tothe cap 37 and the rod 32.

.As shown in Figure 4, the'cover 15 is provided with a filling` cap 40 through which the tank canbe filled with water, as it is desirable in practice to partially fill the tank and to thus 'carry an auxiliary supply of water. As shown in Figures 2 and 3, the cover 1-5 is also provided with'a vent open- :1 ing 41 which allows of the proper circulation of air into andv outof the tank, as will be understood. i

In'Figures 1 and 5 l have shown one form of water level indicatoradapted for use in conjunction with the apparatus shown in Figure 1. lThis'indicator comprises a casing442 sustained on a radiator cap 43 and provided with a central opening 44 which is 11i communication with a tubularmember 45. The member 45 is adapted toV extend .into the radiator when the cap 43 is in appliedposition and to thus allow the passage of water upwardly into the opening 44 where it enters a -transparent tube 45 for lifting a ball 46 to indicate the level of water within the radiator. The upper end of the tube 45 is provided with an opening 45a, and the upper end of the casing 42 is likewise provided with an opening 47. These openings 45a and 47 allow of the passage of air into and out of the tube 45 to effect the proper operation of the ball 46 under theV action of the water. Although I have spev cifically described a particular` form of water level indicator, it is to be understood that any form of indicator can be employed in vconjunction with the apparatus shown in Figure 1.

The operation of the apparatus is as follows: As previouslystated, the tank T is partially filled with water through the filling cap 40. lVith the tank T connected to the radiator R and the pipe P in the manner shown3 it will be vclear that any overflow 0f water from the radiator R or any steam as the result of excessive heating of water in the cooling system, will all pass fromy the radiator through the pipey 18 and to the tank T, the tubular member 20 serving to system. and should this be below a prescribed level; the water. in the'tanki'lcan be supplied to the'cooling systeml byfan opening of the valve 26, thus restoring the normal supply of water contained in the cooling syste f From the foregoing operation, it will be manifest that the apparatus operates to con.-

serve the wateroriginally supplied to ther cooling system and to collect and coolwater and steam expelled from the radiator. ;This obviouslv eliminates thel necessity of stopping to fill the radiator'with water froml time to time and the disadvantages attendant thereto. f

In Figure 1I have shown a vertical portion of the pipe 22 provided with a manually operated valve 48 and a flexible pipe or hose 49 connected to the pipe between the valves 26 and 48. Thepipe 49 is adapted to extend to a remote point for connection with Va source of waterv supply such as theusual auxiliary water tank Ycarriedupon the ruiming board of an automobile. The pipe 49 is'also provided with a valve 50. In operationpthe valve 48 is 'closed and the valve 50- opened, and when the valve 26 is moved to epen'posivm misere tion and with the pump M in operation, the suction created in the pipe 22 by the circulation of water in the cooling system can be utilized to create a suction within the pipe 4.9 and thereby draw the water from the source of supply into the cooling system, This eliminates the trouble of iilling the tank T from time to time through the filling cap 40.

Although I have herein shown and described only one form of auxiliary cooling apparatus embodying my invention it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope ot' the appended claims.
