The :present .inventionrelates to a novel and .1: improvedahingexfor. doors, swingable windows,

and-equivalent closuresand has more particular reference toaimprovements on the type of hingexzwhich embodies duplicate hingedly conplementalr door frame."

It ispwell'known that, ordinarily, a carpenter,

It is.an' object .of the present invention to employ a hingewherein approximately threequarters of each leaf. is omitted, and relatively small, properly positioned attaching extensions or tonguesare substitutedfcr the cut away portions wherebynto appreciably conserve on materialvand to, at the same time, provide a satis factory and reliable hinge.

It is another object of the invention to provide, in certain forms of same, narrow leavesand rectangular. tongues and to attach semicylindri-cal facing members to said tongues, whereby to thus provide adapters which lend themselves to proper installation in semi-circular, instead of the usual mortises.

Itiszanother object-of the invention to pro vide: a :double leaf hinge of the stated type wherein the extension tongues and their adapter --rounds, the

attachments combine to provide half latter-fittingcinto correspondingly shaped mortisesl In addition-this invention is tied in, so to speak; with a special drill holder and guide device which makes it possible to use a brace and bit or simple twist drill for purposes of si- Figure 3 1st a1-fragmentaryhorizontal sectional view showing a door frame and door, and further showing, theaimproved hinge; and the manner:in*whichitherespective parts :are assembled and fastened rtogeth'erw Figure: 4 is an enlarged' fragmentary' sectional view at rightcangles to Figure-3; thesectionbe 111311011 theline 4 4 of :Figure 3, lookingin the direction of. the arrows.

7 3 bers of the respective hinge sections I and come together and abut, they combine to define a cylinder (see Figure 4) and therefore, in practice, a cylindrical bore must be drilled into the door and door frame to accommodate said members. For example, in Figure 3, we see the door frame I 6 on one side and the door I6a on the other and by using the drill and guide block covered in Serial No. 781,048 these parts I6 and I6a are bored and a cylindrical mortise is provided leaving semi-cylindrical mortises I1 and I8 in the respective parts l6 and Ifia. These half-mortises serve to accommodate the corre spondingly shaped half-round attaching members (tongues I2 and adapters I4) for the narrow hinge leaves 9. It is necessary, it is believed, to make proper cross reference and consider this application and the aforementioned co-pending application on the mortising guide block to enable one to understand the guide block, on the one hand, and the novel hinge on the other.

It is not always necessary to build-up the attaching members for the narrow leaves so that they will be of two part or composite form as shown in Figures 2, 3 and 4, especially wherein the adapter or filler member is is hollow. That is to say, it is within the sphere of this invention to employ a modified construction shown, for instance, in Figure 5. In the latter figure, I have shown a fragmentary portion of one hinge leaf or section which is denoted by the reference character la. The narrow leaf portion is denoted by the numeral I9 and the extension tongue, which is integral therewith and rectangular and also narrow, is denoted by the numeral 29 and this has the screw holes 2I to match with similar screw holes 22 in a filler block, of wood, plastic or other material, the same being solid and denoted by the numeral 23. This is simply lined up with the tongue to overlap the latter in an obvious fashion and then when the screws (not shown) are brought into play, the respective parts 23 are thus completely assembled. The only difference seen between the structure seen in Figure 2 and that seen in Figure is that in Figure 2 the adapters M are of hollow formation whereas in Figure 5 the adapter (only one appearing) is solid.

It is also within the purview of this invention to employ attaching members which are of onepiece construction as shown in the modification seen in Figure 6. Here the hinge section is fragmentarily shown and is denoted, as a unit by the reference character lb. In Figure 6 we see the narrow leaf denoted by the numeral 24 and this carries an integral extension for attaching member which is differentiated by reference character 25. In addition to being cast as an integral part of the leaf, the narrow end is semi-conical as at 26 said pointed end being adapted to pilot itself into the correspondingly shaped cavities denoted by the reference characters Na and I8a respectively. Actually these portions Na and I8a are merely the extreme tapering ends of the mortises. In certain drills and mortising tools when the complete circular mortise is bored, the inner end of the tool will leave diminished recesses as indicated at Hat and I8a and by providing the semi-conical extremity 26 on the attaching member this part for said attaching member will project into the cavity to provide a stronger construction. I desire the attaching members to beconstrued as being provided with as well'as being without the pointed extremity 26. The numerals 21 merely designate screw holes in the attaching member It is understood that any number of screw holes may be provided and that, also, any number of attaching members may be provided. That is to say on certain hinges a single attaching member will do. On others two attaching members will serve, that is two on each leaf, and in other circumstances it may be necessary to use three'or more attaching members.

I also desire to utilize the expression attaching member to identify the tongue and adapter I2 and I4, the arrangement seen in Figure 2, and too, the tongue 20 and adapter 23 as shown in Figure 5 and also to cover the one piece construction denoted by the numerals 25 and 25.

It will be seen that the essence of the instant invention relates to a double leaf hinge with common knuckles and a hinge pintle connecting the knuckles and leaves, the leaves being relatively'narrow and provided with half-round extensions or attaching members which make it possible to conveniently screw and fasten said leaves in semi-cylindrical mortises in a door and door frame assembly. Under the combined provisions of the hinges herein covered and the mortising means, lining up of the above referred to door hinges, proper spacing and clearance of door and door frame, and other advantages favoring carpenters are virtually assured.

In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary] It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and within the scope of the appended claim.

Having described the claimed as new is:

As a new article of manufacture, a relatively narrow rectangular leaf having pintle accommodation knuckles provided along one longitudinal edge, and having flat right angularly disposed attaching tongues formed along the opp'osite longitudinal edge, said attaching tongues being in the form of flat extensions provided with screw holes to accommodate wood screws, and a hollow substantially semi-cylindrical adapter for each extension, said adapter being ofa length commensurate with the length of the complemental extension and having the screw holes lined up with the first-named screw holes in order that the screws which serve to secure the tongues and adapters to a door also serve to hold the adapters'superimposed on the tongues.

invention, what is FRANK J. KORNMAYER.
