RADIATOR.

Application led February This invention relates to an improved radiator for internal combustion engines, be-

ing more particularly designed for use in connection with the engines of motor vehicles, and seeks7 among other objects, to

' plates will be assembled iii mating front and rear units bodil removable at the front and rear of the radiator shell, and wherein said units may be thus displaced without thffneoessity of removing the shell from the vehicle.

Andthe invention seeks to provide a radiator well adapted for :general use and which, in practice, will prove entirely efcient.

Other andincidental objects will appear hereinafter.

In the drawings: Figure 1 is a front elevation of my improved radiator. l y y y Figure 2 is a horizontal'sectional vview on the line 2-2 of Figure 1, looking in the direction indicated by the arrows.

Figure 3 is al vertical section on the line 3 3 of Figure 2.

Figure 4 is a detail perspective view particularly showing a typical plate of the front plate unit as well as atypical plate of the rear plate unit employed.

In carrying the invention into effect, I employ a shell which includes a top tank and a'A bottom tank 11 connected with each other-.by parallel side plates 12. The top tank is formed with the usual filler tube 13 ,closed by a screw cap 14, and entering 'said vtank at the back .thereof is an inlet 15 while from the bottom tank leads an outlet 16. Extending between the top and bottoni tanks are transversely spaced rows of vertical tubes indicated for convenience at 17, 18, 19 and 20, communicating with said tanks sotliat water entering at the inlet 15 will flow intothe top tank 1.0 to thence descend through the tubes into the bottom tank 11` when the water will flow out at the outlet 1G. Overlying the bottoni tank between the rows of tubes 17 and 1S and between the rows of 1s, i925. serial No. 10,071.

tubes

19 and 20, are wear plates 2l extending from front to rear of said tank. These wear plates maybe secured to the tank in any approved manner andare provided at their ends with downturned lugs 22 overhanging the front and rear walls of the tank.

- I n conjunction with the tubes, I employ a pair of front and rear mating

radiating plate units

23 and 24. The unit 23 is composed of a plurality of plates 25 each having side tongues 26 and a middle tongue 27 between and somewhat longer than the side tongues. At the outer edges of the side tongues the plateis formed with notches 2S while at its outer margin the plate is foldeil over to form ka reinforcing flange '29 as well as to provide a smooth surface at the outer edge. of the plate. Extending through each of the tongues 26 of the several plates are vertical parallel tie rods 30 provided at their lower ends with heads 31 while at their upper ends the rodsl carry nuts 32, and surrounding the rods between adjacent plates are spacing members 33. As shown in de tail in Figure 4, each of these members is preferably in the nature of acoil spring but in assembling the plates of the unit, the nuts 32 are preferably adjusted until said springs are substantially compressed. Thus, the springs will serve to' more or less rigidly space the plates apart but enough yielda bility will remain in the springs to allow a limited movementof the plates on the rods. ln this way sufficient rigidity of the unitis attained while, at the same time, slight movement of the plates will be permitted to accommodate any excess stresses or strains such as might be inflicted in the practical use of the radiator.4 The unit 24 is likewise composed of a plurality of plates 34, each of which is provided with short side tongues 35 and a somewhat longer middle tongue 36. At the outer edges of the side tongues are notches 37 like the notches 28 of the plates 25 while the outer margins of the plates are bent'uiider to form reinforcing flanges 3S like the fianges 29. -Preferably, the freel ends of the tongues 35 are also bent under to form like reinforcing flanges 39, and extending through tlie side tongues 35 are parallel 'vertical tie rods 40. These rods are identical with the rods 30 and surrounding the rods 40 between the several plates 34 are spacing members 41 like the spacing members 33. Thus, the plates 34 are connected to form the unit 24 and are spaced apart in parallel relation by the members 41.

The

plates

25 and 34 of the

units

23 and 24 are of a length to be slidably received between the side plates 12 of the radiator shell. Accordingly, the units may be assembled with the shell. by first sliding the front unit 23 into the shell at lthe front thereof, and then the unit 24 is slid into the shell at the rear thereof. As shown in Figure 2, the

tongues

26 and 35 of the plate units are slidably received between the rows of

tubes

17 and 18 and 19 and 20, while the

tongues

27 and 36 are slidably received between the rows of

tubes

18 and 19. The tongues 26 overlap the tongues 35 while the tongues 27 overlap the tongues 36 and, as will be observed, the front and rear tubes of the rows 17 and 20-are accommodated in the

notches

28 and 37 of the plates of the units while the front and rear tubes of the

rows

18 and 19 rest in the `ends of the slots between the tongues of the plates for limiting the plates in their movement into the shell, the plates, when in place, lying flush with the front and rear faces of the shell. The radiator is thus given a neat and finished appearance while the plates of the units are disposed in intimate relation to 'the tubes of the shell for radiating the heat communicated to the plates from said tubes. Extending transversely through both units between adjacent plates thereof are upper and lower pairs of clamping rods 42 securing the units together within the shell. Thus, by removing the be slid from the shell at the front and rear thereof, the weariplates 21 being provided lto receive the wear of the heads 31 of the tie rods of the units. As will be appreciated, after the plate units have been thus removed, free access may be had to the vertical tubes of the radiator for inspection or repair.

Having thus described the invention, what I claim is:

1. A radiator including ajshell and having rows of vertical water tubes, a radiating plate unit removably. fitting in the shell and formed to accommodate said tubes, and means securing the unit in position, said unit including a plurality of superposed plates, tie rods extending through the plates, and yieldable spacing members surrounding the rods between the plates and spacing the plates apart.

2. A radiator including a shell and having rows of vertical water tubes, a radiating plate unit removably fitting in the shell and formed to accommodate said tubes, and means securing the unit in position, said unit including a plurality of superposed plates, tie rods extending through the plates, yieldable spacing members surrounding the rods between the plates and spacing the plates apart, and means adjustable upon the rods for compressing said s acing members.

In testimony whereof I a x my signature.
