THOMAS H. B. BOBERSON', OF ST. LOUIS, MISSOURI.

RADIATOR.

Applicationfiled April 22, 1916.

To all whom it may concern:

Be it known that I, THOMAS H. B. ROBER- SON, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Radiators, of which the following to the jackets of the engine cylinders by circuitous radiation thereof in juxtaposition'to a multiplicity of air passages.

It is one of the primary objects of the m-e -,entihvention to devise improved means 1-01 connecting the vertical tubes to the upper and lower chambers of a radiator so as v to permit of a certain amount of vibration or movement of the water chambers without breaking the connection between the walls of said chambers and the tubes, and thereby effectively obviating possible leakage of the water.

invention to simplify and improve the construction of radiators of the above character whereby the several parts thereof are rendered easily accessible for the purpose. of repair, while at the same time the structure as a Whole is rendered exceedingly durable and capable of manufacture at relatively small cost.

With the above and other objects in view,

my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a vertical sectional iew of automobile radiator constructed in accordance with the preferred embodiment of my invention;

Fig. 2 is a horizontal section through one end of the radiator taken on the line 22 of Fig. 1-;

one of the radiator tubes and the Water chambers; and

Fig. at is a similar view showing the manner of connecting the vertical bolts to the upper and lower water chambers.

Referring in detail to the drawing, 5 designates the base section of the upper water chamber of the radiator and 6 the top section thereof. Each of these chamber sections. is formed with vertically disposed marginal walls, and the edges of the marginalwalls on the top section 6 are provided with longitudinally extending, V shaped grooves or channels 7 to receive the V-shaped ribs or edges 8 on the marginal walls of the lower chamber section 5.

The lower water chamber also consists of a base section 9 and a top section 10, the

latter section being formed upon its marginal edges with the longitudinal V-shaped ribs ll'to seat in the correspondingly shaped channels or grooves 12 formed on the vertical marginal walls of the base section 9.

The radiator core consists of a plurality of spaced, vertically disposed copper tubes 13. On the opposite ends of each tube, a reinforcement 15L is cast, having a convex The wall of the bottom section 5 of the top water chamber and the wall of the top section 10 of the lower water chamber are each provided with a plurality of equidistantly spaced openings which are reamed or ground out, as at 15, to produce a perfect fit for the reinforcements or enlargements 14: on the ends of the core tubes.

The sections 5 and 10 of the upper and lower water chambers are also connected by n "HHS of a plurality of vertical bolts 16 threaded upon their opposite ends and extending through tapering openings indicated at 17, formed in the walls of the Water chamber sections. Frusto-conical, soft metal bushings or gaskets 18 are fitted into these openings around the rods 16." On the upper end of each bolt, a spring washer 18 is engaged and rests upon the upper larger end of the gasket 18. A nutl9 threaded upon the upper end of the bolt bears against said washer to force the same downwardly upon the gasket to produce a water-tight joint around the upper end of the rod 16. Nuts 20 are also threaded upon the lower end of each of the rods 16 above and below the wall of the lower water chamber and the upper nut 19 forces the metal gasket 18 tightly into the opening in 0 Elle breaking of lhe ends of the chamber Wall. ihus, possibility of leakage of the Water from the chamber around the connecting bolts is avoided.

A vertically disposed bolt or rod 21 has its lower end engaged through aperlured lugs on the sections 9 and 10 of the lower vvnie chamber. One of these rods is an recall at each corner of the radiator, the r ends of the rods being connected to 22 on the corners of 'the top section 6 of "Le Water chamber. By adjusti f the on the lower ends of said rods, the upper chamber section 6 may be drawn down tightly upon thew-shaped ribs b upon marginal walls of the lower i'iember seciion, and through the medium oi she connecting tubes 13, the upper and lower sections of the lower Water chembe' will also be tightly clumped cogether. i iz i "lill'Pi', sll curls of the radiator 1' nuts y and quickly assembled, and Cl. cements on ends of the v ubes i3 tighfly engaged in the openings 0 is; h

between said chambers, rain the foregoing descripeion, in connection with -the accompanyingdraw- 1 she construct-ion, manner oi operation several advanieges of the invention Will e clearly and fully understood. By mounting the core tubes in the wells of the Water chemoers in the manner above stated, it Will be apparent that the torsional strains so which the radiator is subjected in the vibration oi the vehicle,will not result in the the core tubes, but on the contrary, the reinforcements 14 thereof will oscillate in the openings of the chamber Wells to permit of a limited flexibil or relative movement of she spaced cuter chsn'ibers Without completely disconosses? meeting the tubes therefrom or interrupting the continuous flow of the Water, it will also be seen that Whenever it becomes necessary to repair the radiator or insert new tubes therein, the several parts may be readily disconnected by loosening the lower bolts 2 so thus the core tubes can be quickly removed and replaced by new ones. The rudiubor us a Whole is simple and durable '11 construction, highly serviceable and convenient in practical use and may be menufactured at relatively small cost.

While have shown and described the preferred conslrucsion and arrangement of the several parts, it is to be understood that the invention is susceptible of considcrable modification. therein and l, vhereifiore, re crve ihc privilege of adopting all such le ilimute changes as may be fairly embodied 'vvilhin the spirit and scope of the invention as claimed.

Having thus fully described my inven lion, wht I deeire to cleiin and secure by Letters latent A rudilitor including upper and lower Welter chambers having openings in their opposed "Wells provided with concave seal ing surfaces extending from one face to the other of the chamber wall, a plurality of vertical vater tubes each provided with terminal reinforcements having convex, peripheral surfaces for oscillatuble engagemerit upon said concave seating faces, and

detachable connecting means between the fend-s" of the water chambers to hold the same ':i-nd the water tubes in assembled relation. In testimony whereof I hereunto allix my signature in the presence of two Witnesses.
