MOTOR-VEHICLE.

Specification of Letters Patent.

Patented Mar. 30, 1920.

Application filed June 19, 1916. Seria1 No. 104,460.

To all whom t may concern:

Be it known that I, MILTON TIBBET'rs, a citizen of the United States, and resident of Detroit, lVayne county, State of Michigan, have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specification.

This invention relates to motor vehicles, and particularly to the cooling means-for the motor.

One of the objects of the invention is to provide an improved form of radiator construction.

Another object of the invention is to provide an improved form of closing means for the front of a motor vehicle radiator.

Another object of the invention is to form' a radiator unit with a front closing means that is effective and is pleasing in appearance.

Another object of the invention is to provide a radiator closing means that will shed mud and water.

Other objects ofthe invention will appear from the following description taken in connection with the drawings which form a part of this speciiication, and in which:

Figure 1 is a side elevation and part sectional view of the forward portion of a motor vehicle, embodying this invention;

Fig. 2 is a front elevation of the radiator and associated parts shown in Fig. 1.

Fig. 3 is a horizontal section and partly plan view of the radiator shown in Fig. 1, the shutters being shownin closed position; and

Fig. L1 is an enlarged side 'eleva-'tion of the lower part of the radiator shown in Fig. 1, with parts cut away, and with the shutters in closed position.

Referrin to the drawings, 10 represents a water-jac eted motor mounted on the forward part of a motor vehicle and 11 is a hood of any suitable construction which forms a covering for the motor.

The water circulation system vfor the motor comprises a pump 12`which draws the water from the radiator 13 through a pipe 14, a pipe 15 leading from the pump to the motor water jacket, and a pipe 16 'which carries the water from the motor water jacket to the upper part of the radiator 13. A thermostat 17 of approved con- .the lower tank 23.

struction is mounted in` .la chamber 18 through which the water passes from the pipe 14 to the pump 12. The purpose of this thermostat will be later described.

Afan 19 driven by a belt 20 is mounted proved form and as shown it is composed of l a great many small tubes, each of which is the thickness of the core vand is expanded at both ends. These tubes are soldered or otherwise secured together at their expanded ends, thus providing passages 25 for the water as it, falls from the upper tank 22 to The interior of these tubes form air passages through which the air is drawn by the fan 19 and by the movement of the vehicle. By this arrangement a large cooling surface is provided.

Inthe operation of 'a motor vehicle in cold weather, it is frequently desirable to close off the air passages in the radiator either partly or wholly, to permit the motor to warm up more rapidly or' to operate at the radiator fully operative. In the present invention this is accomplished by a radiator closing means mounted in front of the radiator core, and as shown this closing means shutters will readily shed the .mud andv 'water that may be thrown upon them by the wheels of the vehicle.

For the purpose of automatically operating the shutters 26 and opening them as the temperature of the water in the circula tion system rises, a connection is provided a higher temperature than it would with between the shutters andthe thermostat 17 above referred to. This connection is in they form of a lever 29 having one arm connected by a pin and slot connection 30 with the thermostat and its other arm connected by a rod 31 with an arm 32 secured to one of the shutters 26. -In F ig. 1 the thermostat 17 is shown in an expanded state, thus holding the shutters 26 wide open to obtain the maximum cooling effect of the radiator. It

tom wall 35 extending forwardly from the front face of the radiator core 21 and forming an inclosure in which the shutters 26 above referred to are mounted.- The upper wall 33 is formed by anextended portion of the tank 22, and the lower wall 35 is shown as formedby an extension of the tank 23.

, Also the side walls 34 are formed by forward extensions of the sides 24: of ther-'adi- `ator. These side walls 34 support the pivots 27 of the shutters 26 and the shutters when closed, as shown in Fig. 4, are flush with the forward edges of said wall. This permits of making the radiator and front closingV means in unit form and the unit Yas a whole presents va pleasing appearance.` Also by thus extending the

tanks

22 and 23 forwardly they are given greater capacity without presenting a bulky appearance.v

Other forms may be made without departing kfrom the spirit or scope of the in vention. `i

Having thus described my in'vention, what I claim and desire to secure by Letters Patent is a -1. In a motor-vehicle, in combination, a water jacketed motor and a water circulation system therefor, comprising a radiator having its outer walls extending forwardly beyond the front face of the radiator core,

Y stat, and a connect-ion from the thermostat -to operate the shutters.
