RADIATOR ATTACHMENT.

Application filed Maya, 1926. Serial No. 106,681.

This invention relates to an improvement in radiator attachments and has for its ob ject to provide a simple, economical and eiiicient manner of construction and, at the same time, increasing the speed of produc tion and reducing the cost of manufacture.

Another object is to provide a structure formed of a single sheet of metal which 1s conveniently bent into the desiredshape without being drawn, reduced in thickness or weakened in any manner throughout its entirety.

Another object consists in providing cer tain improvements in the form, construe tion and arrangement of the several parts, whereby the above named and other obpzcts may be effectively attained.

It is particularly directed to radiators for automobiles, but it is of such a nature as to have a wide range of usefulness; some of the applications which we may mention being overhanging tanks, containers for hqulds of any kind having inlets and outlets disposed at an angle to the body of the container, hoppers,.feedersor outlets for gram or the like, etc.

A practical embodiment of our 1nvent1on is represented in the accompanying drawing, in which Fig. 1 represents a plan new of a blank from which my improved structure is formed, D

Fig. 2 represents a front elevation of the structure bent from the blank,

Fig. 3 represents a side elevation of the same,

Fig. 4 represents a vertical section taken in the plane of the line IVIV of Fig. 2, looking in the direction of the arrows, D

Fig. 5 represents a similar view showing the flange formed on the periphery of the hole,

Fig. 6 represents a side elevation of a nipple arranged to be secured to thestrueture,

Fig. 7 represents an end elevation of. the same,

Fig. 8 represents a front elevation of the structure having the nipple applied thereto,

Fig. 9 represents a side elevation of the same, and

Fig. 10 represents a vertical section taken in the plane of the line X-X of Fig. 8, looking in the direction of the arrows.

One method, now in common use, of ap* plying an inclined connection at the junction of two walls of an automobile radiator requires a considerable amount of mechanical skill and manipulation to secure the connection to the walls, as well as an increased cost of material and manufacture of the connection, as compared with our improved method I of construction.

This connection consists of a cast metal nipple having a V-shaped. cut in one end,

which cut is flanked by a peripheralflange. Before each connection can be applied to the walls of the radiator it is passed through a number of manipulations, such as tumbling the rough casting to clean the same,

finishing the contact surfaces of the Vcut, preparing the contact surfaces for sweating or soldering the same to the walls of the radiator, and boringthe flange for the rivets by which it is secured to the walls. Furthermore, it is also necessary that a blank be prepared to form the walls of the radiator to which the connection is to be applied.

By our improved method of construction the same result is accomplished in a more simple and economical manner.

A blank 1 is provided with a hole 2 punched in the proper position, or the hole may be out after the walls have been formed. In the present instance, we have shown the hole cut in the blank before it is bent into shape. The blank is then developed into a form having a vertical wall 3, a horizon tal wall 4, and an oblique wall 55in which wall 5 the hole 2 is located. The faces of the vertical wall 3, the horizontal wall 4 and the oblique wall 5, when developed, will assume a slightly curved formation.

The means for bending this blank is well known to those skilled in the art and may be accomplished by one or more operations which we do not deem necessary to describe herein as it serves no purpose in the present invention.

In forming the oblique wall 5 between the vertical and horizontal walls it will be seen that the main contour of said wall at the junction of the vertical wall assumes a curved line 6, the ends of which terminate at the junction of the vertical and horizontal walls, while the main contour of the wall 5 at the junction of the horizontal wall l takes the form of a curved line 7 which meets at the junction of the vertical and horizontal walls and at the termini of the line 6.

After the walls have beenl-ormed the periphery of the hole 2 is worked to develop a flange 8, in any well known or approved manner.

A nipple 9 is cut from common tubing of brass or other suitable material, the desired thickness and predetermined length, and one end is manipulated in any well known or approved manner to turn the edge outwardly at right an les to the longitudinal axis of the nipple to orm a peripheral flange 10.

This nipple 9 is inserted in the hole 2 so that the flange 8 of the hole will contact with the exterior wall of the nipple, and the flange 10 of the nipple placed in intimate contact with the oblique Wall 5. The nipple 9 will, of course, be disposed substantially at right angles to the oblique wall 5 and secured in the wall by sweating or soldering in any well known or approved manner. The manner of applying the nipple in the holein the oblique wall effects a very desirable joint which maybe easily and readily sweated or soldered.

Thus it will be seen that the method of constructing this unit requires little or no skilled labor and the cost of manufacturing minimized, while the speed of production is greatly increased as compared with the method nowin common use.

It is obvious that various changes may be effected in the form, construction and assembling of the arts, without depayting from the spirit and scope of our invention; and hence, we do not intend to be limited to the details herein shown and described except as they may be included in the claims.

hat we claim is:

1. A sheet metal radiator attachment having a portion adapted to receive a niaple, said portion including three curved sur aces, each disposed at an angle to another.

2. A sheet metal radiator attachment having a portion adapted to receive a nipple, said portion including three curved surfaces, each disposed at anobtuse angle to another.

3. A sheet metal radiator attachment including three curved surfaces, each disposed at an obtuse angle to another, and a. nipple having a peripheral flange disposed at right angles to the longitudinal axis thereolf and secured in one of said surfaces. t

4. A sheet metal radiator attachment including three curved surfaces, each disposed at an obtuse angle to another. and a nipple having a. peripheral flange disposed at right angles to the longitudinal axis thereof and secured in the intermediate surface.

5. A sheet metal radiator attachment including three curved surfaces formed integral with each other, each disposed at an obtuse angle to another, and a nipple having a peripheral flange disposed at right angles to the longitudinal axis thereof and secured in one of said surfaces.

6. A sheet metal radiator attachment including a curved substantially vertical wall, a curved substantially horizontal wall, a curved oblique wall interposed between said walls, and a nipple having a peripheral flange disposed at right angles to the longitudinal axis thereof and secured in said ohlique wall.
