Y COOL ING DEVICE FOR BADIATORS-FOR AUTOMOBILES Application filed December 14, 1928. Serial No. 325,980.

This invention relates toan accessory capable of use in numerous different associations, but primarily intended to be employed in connection with a motor ofthe'internal combustion type and specifically, the cooling system of such motor.

It is an object of the invention to provide a device of this character which, in use, will serve to prevent a cracking of the radiator is core and will achieve this result by assuring a more rapid and even dissipation of heat than has generally been achieved heretofore.

A further object of the invention is that of furnishing an accessory of this nature the parts of which will-be relatively few in number and individually rugged in construction, these parts being capable of being manufactured and assembled, as well as applied to the cooling system with facility and by unskilled 2e labor, so that an economical article of this type is furnished.

An additional object is that of furnishing an accessory for this purposewhich will have a pleasing appearance and which when placed in association with a radiator core will not injure the latter. r

With these and further objects in mind reference is had to the attached sheet of drawings illustrating one practical embodiment of 0 the invention and in which Figure 1 is a partly sectional view taken through a radiator shell and core and showing the same disposed in the conventional manner adjacent the motor block and furthermore illustrating the accessory in applied position; Fig. 2 is an enlarged sectional view of such accessory, and d Fig. 3 is a partly fragmentary face View thereof. 7

motor block in advance of which, in the usual manner, a fan 6 is carried as, for example, by means of a bracket 7, this fan being 4 driven by a belt 8. In turn disposed in derstood that the water carrying with it some In these'views thenumeral 5 indicates the advance of the fan is a radiator core 9 having of the surplus heat in the motor moves into the head and then down through the honeycomb of the core, where it is cooled and thereafter. circulates. back to thelmotor, either under the influence of a pump or incident to the a natural circulation induced. by heating and cooling of the fluid. In any event, in order to assure a flow of air through the interstices of the radiator, this air streambeing sufiicient to effect cooling, the fan is provided.' Under certain conditions it has been found that that portion of the radiator core which receives the water heated to the highest degree tends to crack under the action of such heat. This defect is attributed to the extreme conditions to which the core is subjected at this point, to

wit first, the most highly heated water is within the core adjacent the point at which it is liable to crack and, secondly,'too greatan amountof air is sucked through the radiator core at this point, resulting in rapid fluctuations of temperature and corresponding expansions and contractions of the metal from which the core is formed. j i

. In order to overcome difficulties in this con i nectiona cooling device is attached to the .radiator' in order to conduct surplus heat from this local section of the core. Thisconducting element preferably includes bracket portion 12 through openings in which bolts 13 may'eXtend, these bolts mounting washers 14: of suitable material to assure against dam age to the radiator core and carrying nuts 15 to assure a proper clamping contact. The bracket, adjacent its upper end, mounts a disk 16 to which plates 17 are secured, these plates carrying or being encircled by a band portion 18 which, if desired, may have a radial series of projections 19 simulating in appearance the cylinders of a motor. A bracket .20 has its inner ends attached to the outer edge of the band 18 and mounts one section of a ball bearing 21, the opposite section of which may conveniently mount a spinner 22 having blades 23 secured thereto. 5 These blades acting as a fan, under the influence of the air currents, will necessarily revolve andas a consequence of being in line with the air column drawn inwardly by the fan, the speed of'revolution will be comparatively high. This is quite independent of the impulse imparted to the fan incident to the movement of the vehicle with which it is associated. Irrespective of this, however, it 5 will be obvious that in so revolving the fan or miniature propeller will necessarily break up any local and intense air streams induced by the rotation of the fan 6.

Thus, by means of the present accessory a q structure is provided which serves constantly to conduct heat away from that portion of the radiator core which is subjected to the highest degree of temperature. Moreover, such accessory serves to prevent too intense (in-face cooling at this locality and by means of the present invention it is moreover feasihle to mount the accessory on the core without ury thereto, aside from the fact that a novel construction is furnished which will 29 operateover long periods of time without any attention.

As a consequence it has been discovered that the likelihood of damage to the radiator is reduced materially and moreover, the ac ccssory thus provided is pleasing in appearance and ornamental when applied to the vehicle with which it .i associated.

From the foregoin it will be appreciated that, among others, the objects specifically :,-;raforementioned are achieved. It is intended,

however, that numerous changes in construction and rearrangement of the parts might be resorted to without departing from: the spirit of the invention as defined by the claim.

Having described my invention, what I claim as new and desire to secure by Letters Patent is A device of the character described includao ing a band, a bracket extending in advance of the same, a bearing carried by said bracket, a spinner mounted upon said bearing and overlapping said band and propeller blades secured to said spinner.

45 In testimony whereof I aflix my signature.
