This invention relates to What are known as covered joint hinges and particularly to hinges of this type designed for use in connection witmotor vehicles to hin edly support the doors in connection With vehicle bodies; and the object of the invention is to provide a hinge or the character defined, the hood loutt. part of which is formed from two substantially similar sheet metal blanks arranged and nesting one within the other to form complete hood butt whereby the cost of production of a butt of the class described is reduced, and at the same time, a stronger and more durable outt is provided; and w these and other objects in view, the'invention consists in a hinge of the class and for purpose specifled, which is simple in construction, efiicicntin use, and which is constructed scribed and claimed.

The invention is fully disclosed ing specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:

Fig. .l is a side edge view of a hinge made according to my invention.

In the art of manufacturing hinge butts of the kind under consideration, it old to iorrna butt from a single piece of cast or iged rrwal and' from machined rolle sections as well as to provide a butt consisting of a thin outer shell with a heavy or relatively thick insert. It is the purpose of my invention to eliininate'the conventional methods of procedure and'to construct a hinge loutt from two substantially similar sheet metal parts which collectively will form a strong and durable butt of therequired contour and dito suit for the intended so.

'To illustrate one method of car ying by invention into effect, I have shown of the drawing a hinge oomisting of two :3 the butt 5 having tion 2 with a curved hoe followas hereinafter de- 1935, Serial No. 10,963

wt of the cylindrical bearing so of the butt l which extends between adjacent surfaces of the bearings ltl, i

The invention deals with the construc-' tion or" the butt ine nber In practice. this butt member is comp-c d or two parts, namelv'an outer part ii and an er art both of which fashioned from sheet metal and which are of substantially the general contour ormay -ght structural oinis ions. 1 i e outer part comprises an attaching plate L l-tron 53 having side flanges 5&{110133 Fig. 4, and or" said a curved Wall 55 mine; a continuation of the plate and part ally the hood The outer end porof the curved wall is also curved or bowed or wardly between the side edges of the-metal strip or sheet as may be seen upon a consideration of Fig. of the drawing. This butt 0011-. structicn ad, .idity to the hood portion of the butt and also enhances the appearance thereof. As a continuation of the upper and lower edges of curved portion i5 well as the side edges of the plate G2 are and bottom cover plates which "partially i'orm theplates or hearings, i i, we. These plates include rearwardly directed exteons l which cover the space between the bu ts and i at the outer end portion of the lungs as will. appear upon a cone sideration of Fig. of the drawing, The plates are provided with apertures it? for receiving usual uintle not shown, employed to la the two butts 5i and 3 coin portion slightly no. rower in width and preferably seating the flanges i l and of a thi kness equal to the height of the flanges. In other Words, the flancn omitted the plate portion i end of theplate portion lilo is a curved portion inc part it. of the butt 6 the extensions 5 l, and apertures Eda alinement with the apertures :18. It will thus be apparent that the two cover plate portions is, Elia will ch overlie and cover the corresponding ends form relatively thick pintle bearings in, Hia on the resultant butt member and the curved hood portion 9 of said butt member as well as the attaching plate portion 8 thereof will be reinforced and strengthened by virtue of the use of the two sheet metal parts which are arranged to fit snugly one within the other and may, if desired, be pressed one within the other under pressure, and further, may be welded together to prevent any possible shifting or displacement of the parts one with respect to the other. At [9 in Fig. 2 of the drawing I have indicated two welded portions.

The separate butt parts i i and 92 will be fashioned from suitable blanks and shaped to the desired form and contour by the use of suitable dies, thus providing a low manufacturing cost of said parts including the butt as a whole when .24 thereof.

the parts are assembled. At the same time it will appear that a'hinge butt of strong and durable characteristics is produced. By virtue of the manner of constructing the pintle bearing portions I 0, 10a, there is no possibility of the spreading or opening of such bearings which has been experienced with other types of hinges including inserts having rolled or curled pintle bearing portions.

Where the question of appearance is 'not an important factor, the hood end portions of the two butt parts may be made identical in design and contour and arranged to fit snugly one within the other, it being understood that the cutting out of part of the curved hood portion of the inner part as shown in the accompanying drawing is merely to adapt the hinge to the design and contour disclosed. V

. In Fig. 6 of the drawing I have shown a slight modification. In this construction, the outer part 23 and inner part 2| of the butt are of the same construction throughout; in other words, these parts have hood portions 22 and 23 respectively which are continuous to the outer or free edge The top and bottom walls of both hood portions or parts forming the pintle bearings, one of which is shown at 25 in Fig. 6, are substantially the same as the bearings I6 shown in Fig. 2, the only difference being that the pintle aperture 26 of the bearings 25 is located inwardly a sufficient degree to provide clearance for the pintle bearing of the other companion butt of the'hinge to clear the hood portion 23, as will be apparent. With this construction, the

7 side flanges such as shown at M in Fig. 2 of the unite the parts against separation, and protruding edges of the inner part 2! or thehood portion 23 and walls 25 thereof will be trimmed to correspond to the size and contour of the similar portions of the outer part 20 of the butt. The apertures 26 are formed after the two parts have been assembled.

While welding is not essential with the construction shown in Fig. 6, the attaching plate portions 20a, 2| a of the parts 20, 2| may be welded together if desired. While I have stated that the two parts 26, 2! may be of identical size and'construction and assembled in the manner above defined, the inner part 2i may be made slightly smaller than the outer part or to forcibly fit within the outer part so as to insure firm engagement of adjacent walls, especially throughout the hood end portion of the resultant butt.

The thickness of the sheet metal'employed in the separate butt parts may be varied to suit the requirements in the wall thickness of the attaching plate portions of the butts as well as the pintle bearing portions thereof. In other words, if quarter inch thicknesses are required in the resultant butt, one-eighth inch sheet metal will be employed; whereas, if three-eighth inch is desired, three-sixteenth inch sheet metal will be employed, etc.

My improved hinge may be constructed from two sheet metal parts of substantially the same contour wherein one part is constructed from a sheet of metal thinner than the other part, but in all such cases, the pintle bearing portions will be formed from the two sheet metal parts and bent or drawn inwardly from opposite side edges thereof by suitable dies which also form the hood portions.

Hinges of the class under consideration may be economically produced by reason of the fact that all machine operations such as grinding, planing and the like are eliminated. At the same time, finished surfaces are provided for receiving the companion butt of the hinge.

The more important phase of the present invention is in the provision of the reinforcement of the hood and the provision of the relatively thick pintle bearings which could not be practically formed in a single pressed sheet of metal unless the workpiece were first heated, the expense of which operation would again materially increase the cost of production of the resulting product. It is one of the outstanding features of my invention to produce the desired structural result in the most economical and practical manner and at the same time produce a hinge butt of added strength and utility as compared with other butts of its kind.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is: a
