Patented Mar. 1, 1932 UNITED STATES JOSEPH 8088, 01' BOSELLE, NEW JERSEY HINGE BUTT AND METHOD OF MAKING THE sum Application filed December 27, 1929. Serial No. 416,785.
This invention relates to hinges of what are known as the covered joint type and particularly to the method of making the butt of such a hinge which includes the hood for covering or concealing the joint of the hinge; and the object of the invention is to provide an improved and simplified method manufacturing hings butts of the class specified from a sheet metal blank wherein two identical butts are fashioned in one series of forming operations, thereby materially reducing the cost of manufacture, and further whereby the resulting products will be more accurately produced at a minimum waste in scrap material; a further object being to provide a novel method of forming a pair of hinge butts of identical construction wherein the hood portions of said butts are fashioned from the central portion of the blank in such manner a to equally distribute the distrbution of the flow of metal in shaping the hood portions therefrom and prevent creeping or other displacement of the workpiece; and with these and other objects in view, the invention consists in a hinge-of the class and for the purpose specified, made in accordance with themethod more fully hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the accompanying drawings, form 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. 1 is a longitudinal, sectional view through a hinge butt made according to my invention.

My invention relates primarily to the formation of binge butts constitutin one butt vpart of a complete hinge and sai butt part may include other members or parts in forming the complete butt. While this 55 butt may be formed from relatively thin sheet metal in the preferred form of the construction and especially when used as a complete butt part, the same is fashioned from a comparatively heavy sheet of metal.
In Figs. 1 and 2 of the drawings, I have shown one of a pair of butts formed according to my improved method. In said figure, 10 represents the attaching plate portion of the butt which includes a plurality of screw receiving apertures 11 through which screws may be passed in mountin the butt in connection with a support. t one end of the butt is a curved semi-circular hood portion 12 terminating at its free end in a stop wall 13, and said hood including side wall members 14 formed integrally with and as a unit part of the hood portion 12 and shank 10, said walls having rounded outer edges 15 which gradually taper into the attaching plate as indicated by the curved portion 16. Said side walls 14 have oppositely disposed apertures 17 to receive the pintle pin of the hinge which also passes through a knuckle on the other butt of the hinge, not shown, which operates within the chamber formed between the sidev walls 14 and the hood 12.
In forming a pair of hinge butts shown in Figs. 1 and 2 of the drawings, I employ a blank 18 substantially similar to that outlined in Fig. 3 of the drawings, the relatively straight end portions 10a of the blank forming the attaching plates 10 of the separate butts, the adjacent portions 12a forming the hoods 12 of said butts, the latter being joined by an intermediate section 19. Disposed at opposite sides of the parts 12a of the blank are outwardly extending rounded portions 1411 from which the side walls 14 of the butts are formed.
After properly laying out the blank 18, the next step in the operation of forming a pair of hinge butts consists in placing the blank within and between two dies 20-21. In the present instance, the die 20 constitutes the male member and the die 21 the female member. The die member 20 has a punch end 20a, two side walls 20?) of which are beveled in the manner seen in Fig. 4 of the drawings, whereas the other side walls are also beveled as seen at 200, note Fig. 5, the latter walls terminating in rounded portions 20d. The die member 21 has a recess 21a formed therein to receive the blank and the punch 20a, two side walls 216 being tapered to correspond with the taper of the walls 20?), whereas other side walls 210 are tapered to correspond with the taper 200, it being further noted that the corner edges 206 of the punch 20a are rounded as are also the edges 21a of the die member 21, so as to partially form the curvature of the hoods 12 from the portions 12a of the blank in the manner indicated in dotted lines in Figs. 4 and 5 of the drawings.
In the first forming operation oftthe blank, it will be seen that the sections 14a are turned upwardly as indicated in Figs. 4 and 5 of the drawings, and said sections are arranged at a slight inclination to the vertical plane. In other words, said sections are not disposed at right angles to the transverse plane of the blank as in the finished hinge butt. It will also be noted in this forming operation that the flow of the metal is distributed by virtue of the exertion of equal pressures upon opposite sides of the central portion of the blank, and thus the tendency of creeping of the workpiece or blank is obviated.
The female die member 21 also preferably includes an ejecting plug 22 so that the fashioned workpiece may be readily removed.
After the blank has been fashioned in the manner and by means of the dies as seen in Figs. 4 and 5 of the drawings, the same is placed in and between other dies 23 and 24, the latter being employed to finish and complete the formation of the pair of butt members, the die member 24 having oppositely disposed and upwardly projecting members 24a having rounded outer peripheral surfaces to form the desired wall contour to the inner surface 126 of the hood 12, said pro'ecting members 24a having relatively straig t side walls 246 which taper sufiiciently to release the workpiece or product from said die member. Intermediate the members 24a is a straight outer surface 240 which terminates at its ends in angularly disposed surfaces 21d so arranged as to form the desired angle to the free edge 13 of the hoods 12 of the respective butts. At opposite sides of each of the pro]ecting members 24a, the upper ed e of the die 24 is curved as seen at 24c an 24f to form the curvatures 15 and 16 in the edges of the side walls 14.
The die member 23 has oppositely disposed sockets 23a, the contour of one of which may be seen on an examination of Figs. 6 and 7 of the drawings and such as to form in conjunction with the contour of the members 24a the proper contour and formation of the hoods 12 of the respective pair of butts.
Disposed between the sockets 23a is a downwardly projecting member 23?) adapted to operate upon the central portion 19 of the blank as formed from the dies shown in Figs. 4 and 5 of the drawings to depress said central portion in the formation of the hoods 12 and to leave a. connecting fin 25 between the edges 13 of the hoods 12 of the pair of butts formed which is severed by a punch or in any other desired manner in separating said hood parts to form two complete and identical hinge butts similar to that shown in Figs. 1 and 2.
In the above operation it will be understood that the excess metal that may be contained in the portions 14a and which may be formed by the drawing operation of the portions 12a of the blank is firmly compressed into a single mass forming the end wall struc' tures 14, which upon a consideration of Fig. 2 of the drawings will clearly appear to be of a thicker cross sectional form than that of the sheet metal from which the butt is formed and this variation and thickness might for example be as follows. If three sixteenths of an inch sheet metal were employed in the blank, the resulting thickness of the walls 14 might be one quarter inch greater or less in thickness. At the same time, it will be noted that the thickness of the hood portion 12 and especially the free end thereof is relatively thin. In this connection, it will be understood however that my invention is not necessarily limited to any variations in the thickness of the metal in the several parts of the butt nor to variations herein specifically set forth as this may be changed to suit any particular requirements in the resulting hinge butt.
It will also be understood that any slight flare of metal that may exist around the edges of the walls 14 may be removed after the product has been removed from the dies 23 and 24 and in completing the formation of the butt, the hole 17 will e drilled or otherwise formed in the walls 14 to receive the pintle of the hinge.
In connection with the formation of the hinge butts, attention is directed to Fi 8 of the drawings wherein a slight modi cation in the resulting product is shown which consists in including in conjunction with the side edges of the attaching plate 10 of the butt side flanges or walls 26 which extend onto and will be continuous with the side walls 14 of the hood 12 and to form a pair of butts of this character only a slight change is necessary in the formation of the separate die members -21, 23 and 24 to facilitate the formation of said side walls.
In forming either form of hinge butt disclosed, the successive operations may be performed under what is known as a cold formingprocess or without applying heat to the blank or workpiece. In other cases however,
it will be desirable to heat the workpiece prior .to its several operations and especially the forming operations performed by the dies 20, 2.1, 23 and 24. On the other hand, it will be apparent that the operation performed by the dies 2021 may be conducted under the cold process after which the, blank thus formed may be heated and the complete forming operation performed by the dies 23 and 24: may be conducted in accordance with the hot process. The several heating processes are preferably employed when the sheet metal from which each pair of hinge butts are formed is comparatively heavy.
lit will be apparent that my invention is not limited to the specific manner or method of forming a blank which is provided prior to shaping the same into the resulting pair of hinge butts. These blanks may be formed in accordance with any of the known processes, and in referring to sheet metal, it will be understood that this term is descriptive of the general nature of the blank formed. In like manner, my invention is not limited to the specific structure of the hinge butt herein disclosed.
It will also be understood that various changes in and modifications of the specific structure of the hinge butt herein shown and described and the method herein set out for fashioning the same, may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.
