CONCEALED HINGE Filed April 22, 1938 INVENTOR JOSEPH 5053 BY W ATTOR EY Patented Oct. 24, 1939 UNlTED STATES PATENT OFFIQE Application April 22,

6 Claims.

This invention relates to concealed hinges and particularly to the construction of the housing butt part of hinges of this type, and the object of the invention is to provide a housing butt part formed from a single sheet metal blank folded to form a U-shaped housing portion with attaching plates extending from one side edge of top and bottom walls of the housing at an angle greater than 90 to the web of the housing so as to adapt the housing butt of the hinge to a wide throw hook-shaped butt, and with these and other objects in view the invention consists of a device of the class and for the purpose specified, which is simple in construction, efiicient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts 20 of my improvement are designated by suitable reference characters in each of the views, and in which:

Fig, 1 is a plan view of a hinge made according to my invention with part of the construction 5 broken away and also indicating the open and closed positions of the butts.

Fig. 2 is a view looking in the direction of the arrow 2 of Fig. 1.

Fig. 3 is a side edge view of the hinge as seen in Fig. 1.

Fig. 4 is a view similar to Fig. 1 showing a modification.

Fig. 5 is a section substantially on the line 5-5 of Fig. 4, and 35 Fig. 6 is a plan view of a blank from which one of the butts of the hinge is formed.

In Figs. 1 to 3 inclusive I have shown a hinge consisting of ahook arm butt part Ill and a housing butt part I I. The hook arm part in the structure shown is substantially in the form of a bolt or rod shaped to form the desired hook-shaped arm I2. One straight end of the rod I3 is threaded to receive nuts or other attaching devices I4, whereas the other end of the arm is enlarged as seen at I5 to form a desired bearing for the pintle it of the hinge.

The butt part H is formed from a blank l in shown in Fig. 6 of the drawing. The blank consists of two substantially rectangular plate portions I'I extending into wall portions I8 which form the top and bottom walls of the housing of said butt part which are joined by a web or wall I9. The blank is so shaped and folded as to bring the Web or wall I9 of the housing in the angular position with respect to the attaching 1938, Serial No. 203,520

plates IT, as seen in Fig. 1 of the drawing, as well as to ofiset the web I9 with respect to one side of the attaching plates. The angularity between these Wall portions is greater than 90 as will be apparent. At this time it will be understood, however, that this angularity may be varied to suit different types and kinds of hinges or installation of hinges.

The wall portions IB also include protruding pintle bearing portions 20 which are arranged on the inner side of the web I9 when the butt II is formed, as will be apparent upon a consideration of Fig. l of the drawing. The portions 20 will be apertured as seen at 2| to receive the pintle I6 of the hinge. At the outer side of the attaching plate portions I! are projecting tongues or flanges 22 which remain in the plane of the plate I'I. These flanges will preferably abut as seen at 23 in Fig. 2 of the drawing when the butt part II is completely formed.

It is also preferred that the top and bottom Walls I8 be reinforced by V-shaped corrugations 24 to give greater rigidity and strength to said walls and to increase the bearing strength thereof.

In Figs. 4 and 5 is shown a modification in which the butt part I Ia diifers from the butt part I I simply in doming the projecting pintle bearing portion 20a outwardly in the manner clearly seen in Fig. 5 of the drawing. The pintle pin or rivet Ilia is disposed centrally of the domed portions. The parts or elements I'Ia, I8a, I9a and 24a are the same as the corresponding parts or elements I1, I8, I9 and 24 of the butt II.

At 25 is shown a hook arm butt part which is substituted for the butt part II]. The butt part 25 is formed from two similar sheet metal blanks in accordance with the teachings of a companion application Serial No. 203,521 filed of equal date herewith, which application has matured into Patent No. 2,163,713 of June 27, 1939. Each blank is shaped to form an attaching plate portion 26, hook arm portions 21, reinforced as seen at 28. The hook arm portions 21 are disposed one directly upon the other and spot-welded or otherwise secured together as indicated at 29. The ends of the hook arms 2! have outwardly pressed dome portions which seat in the dome bearings 20a. of the butt IIa, as clearly seen in Fig. 5 of the drawing. It will also appear that the arms 21 fit snugly within the top and bottom walls I8a of the butt housing Ila so as to provide a strong bearing for the butt 25 in the several positions thereof with respect to the butt part II a.

With both forms of construction shown, the outward swinging movement of the butts I9, 25

is checked by the engagement of the hook arm with the angular web l9, 19a in the manner indicated in dotted lines in Fig. 1 of the drawing. As previously stated, the angularity of this web and its arrangement with respect to the pintle of the hinge may be varied, within certain limits, to suit various types and .kinds of installations. In like manner the shape and contour of the hook arm of the butts iii, 25 may be varied. Both forms of hinges disclosed to illustrate certain uses of my invention are of simple and economic construction, and at the same time a strong and durable hinge is provided which may have many uses, but which has a practical use in hingedly mounting a vertical door in connection with the door frame.

In many types of vehicles, such as motor vehicles, airplanes and the like, the trend of streamlining such vehicles renders it desirable and practical to use the concealed hinges. To satisfy this use, it is also desirable to produce an economical hinge in order that the cost thereof will :not be prohibitive.

It will also be apparent, however, that a hinge of this type is practical in the mounting of the dors of large cabinets, closets and the like, and in fact in connection with doors or closures of any kind or class where it is desirable and practical to use a hinge of the concealed type.

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