2,625,412 7 RADIATOR HEADER nose FITTING Fred M. Young, Racine, Wis., assignor to Young Radiator Company, Racine,- Wis., a company of Wisconsin Application June 17, 1948, Serial No. 33,485

1 Claim.

The present invention relates to a novel fitting and method of manufacture of a hose connection for a radiator header.

The principal object of my invention is to provide a fitting which is made from the same kind of material and having about the same thickness as the thickness of the header tank material, the rear panel of the tank having a horizontally elongated opening which is surrounded by the fitting and having an area somewhat larger than the area of the tube part of the fitting, whereby expansion and contraction between the contacting parts will be similar and, whereby turbulence will be reduced to a minimum thusto avoid resistance to the flow of the liquid.

In forming or drawing thin metal parts, it is necessary to avoid damaging the material at bends and where the material is stretched. In the present invention the shape of the parts is such as will insure against such damage.

Generally stated, objects of my invention are toprovide fittings of the character which are attractive, strong, efiicient and easily manufactured at low cost.

It will be understood that the present invention is largely adapted. for the inletconnection of the top header of a radiator. However it may be used as an outlet connection on the bottom header of a radiator and in headers having a somewhat different shape than shown.

To these and other useful ends my invention consists of parts, combinations of parts or their equivalents and method of manufacture, assembling and attaching to the header as described and claimed and shown in the accompanying drawings in which:

Fig. 1 illustrates a partially sectioned upper header for a radiator, the section being through the fitting.

Fig. 2 is a rear view of the fitting as shown in Figure 1 showing a fraction of the header.

Fig. 3 is a top view of the fitting as shown in Figures 1 and 2 showing a fraction of the header.

Fig. 4 is a side elevational view of a modification and illustrating a fraction of a header.

Fig. 5 is a transverse sectional enlarged view of the fitting shown in Figure 4 and illustrating a fraction of the header.

The upper header for a radiator is generally considerably wider than the width of the lower headers. This is done principally in order to provide capacity for the water or cooling fluid. In Figure 1 an upper header is shown and designated in its entirety by reference character A and the tube plate of the header is designated by 2 reference numeral H. The top and bottom headers of radiators are generally connected together by means of flattened tubes I2 having closely spaced fins (not shown) through which the tubes extend.

Header A generally has a filler cap I4 which is attached to a tube IS, the tube being secured to a raised portion generally on the longitudinal center of the header. The rear side of the header, particularly at the longitudinal center thereof is preferably ofiset downward as at l6 forming atop plate l'!, the rear plate of the header being designated by numeral I81. Before the header is assembled by adding the tube plate, the top portion of the header is generally called the tank, therefore members l4 through l8 may be considered as parts of the tank of the header.

I provide preferably a bracket I9 which is positioned as shown and secured to member I! as a rest for the hood or covering for the engine. Rear tank plate I 8 has an opening 20. This opening is considerably longer than its width for a purpose which will hereinafter appear.

My improved fitting in its entirety is designated by reference character B and includes a short tube 25 having preferably a raised portion 26 around its periphery adapted to more firmly grip the hose connection 21. This member is made from substantially the same kind and thickness of material as the header tank. The other part of member B consists of a member 28 formed preferably from a flat sheet of the same material as the tank and having about the same thickness.

Member 25' has a shape about as shown in the figures, the upper end having a flange 29. Its forward edge 38 is bent downward and is adapted I to lie against plate H! as clearly shown in Figures 1 and 2. Flange 29 has formed thereon an upwardly extending flange 3| which is formed integrally with flange 29 and member 30.

Member 28 has a shape about as shown in the figures, having a flange 36 around its bottom surface which is formed integrally with a flange 31 and adapted to be on the same plane as flange 30, so that flanges 35 and 37 surround three sides of opening 26. Flange 31 is formed integrally with the top of member 28 which is extended forward over panel I! and designated by numeral 39. An offset 38 in the connection between members 28 and 39 is adapted to lie on the curved surface of the tank, thus forming an excellent surface for bonding the contacting surfaces adjacent opening 20. An opening at 43 and another opening in member 39 which corresponds with the opening at 40 is provided for the reception thus forming a leak proof joint between fitting B and the tank of header A.

It will be seen that the three rivets at 49 will firmly hold the fitting to the tank while being bonded thereto and because flanges 39 and 39 are riveted and bonded to the outer surfaces of members i1 and [8, a firm joint is made between the fitting and the tank; that the fiow of liquid from tube 25 into the header will be free and accomplished with little turbulence or resistance; that expansion and contraction between the contacting parts will be similar, thus to avoid fractures of the material or loosening of the bonded joints and as recited in the preamble of this specification, the fitting will have a pleasing appearance, be light and strong and can be manufactured at low cost.

In Figures 4 and I illustrate a fitting that is somewhat similar to the fitting shown in Figures 1, 2 and 3 which in its entirety is designated by reference character C, comprising a main body 4 I, the forward part of which is oblong as in Figures 1, 2 and 3. In these figures the tank is designated by reference numeral 42, the tube plate by numeral 43 and the tank bracket by numeral 44. The rear plate of the header tank is designated by reference numeral 45 and the top plate of the header is designated by numeral 46. A flanged opening 41 is shaped about like opening 20 in Fi ures 1, 2 and 3 except the opening is slightly lower and provided with an inwardly turned flange adapted to fit around the adjacent portion of member 4| as illustrated in Figure 5. The upper front end of member 4| is offset upwardly as at 48 and forming a surface 49 adapted to lie on the underside of top plate 46 of the tank and is riveted to this surface by a rivet 50, thefront edge of member 4| being cut away as at 51 forming a shape which can be inserted into opening 47. After rivet 59 is applied, the fitting is held firmly into position, after which the flange of opening 41 and plate 45 is bonded to member 4|. Member 4| is rounded at its rear end forming an opening which extends rearwardly and downwardly into which a short tube 52 is inserted and bonded thus forming a surface similar to the lower end of tube 25 in Figures 1, 2 and 3.

It will be noted that Figure 4 is about the same scale as Figures 1, 2 and 3 and that Figure 5 is somewhat enlarged; that member 39 and its rivet as shown in Figures 1, 2 and 3 operate very similar to extension 49 and rivet 50 in Figures 4 and 5 and in a manner which after the rivets have been set and the joints bonded, to provide a very strong fastening between the tank and fitting. Thus clearly applicants fittings will meet the requirements set forth in the preamble of this specification.

It will be understood minor detail changes may be made in the design shown without departing from the spirit and scope of my invention as recited in the appended claim.

Having thus shown and described my invention, I claim:

A hose connection fitting for a radiator tank having an opening in its rear panel, comprising in combination, an inverted cup shaped member formed with front and bottom edges, said front and bottom edges having integrally formed thereon outwardly extending front and bottom flanges, the front flange being adapted to register with the top and sides of said opening, having a portion of the top edge of the front flange extended forward and adapted to lie on the top panel of the tank, the entire front flange being bonded to the rear and top panel of the tank, another member comprising a tube, having on its upper end an outwardly extending flange, a portion of the front edge thereof being extended downwardly and adapted to lie on the rear panel of the tank and adjacent the bottom of said opening and being bonded to the rear tank panel and to the bottom edge of said front flange, its remainder being bonded to the bottom fiange of said cup shaped member, forming a leak proof connection between the tube of said other member and the interior of said tank.
