UNIVERSAL noon-FRAME.

Specification of Letters Iatent. Pafehted Sept, 15 7 1914,

Application filed December 10, 1913. Seria1No.-805,673.

To an. 'w/zom it mav/ concern Be it known that I, VVILLIAM F. EIOHIELD, a citizen of the United States, and a resident of the city of Milwaukee,'in the county of Milwaukee and Stateof VVisco'nsin, have .invented certain new and useful Improvements in Universal DoorFi-aines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the'accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

- Metallic doors and metallic door framesare used to a great extent in large ware houses and other buildings for commercial purposes, in which a strong and fireproof door is desired. It is veryseldom that the building specifications call for a standard together by intermediate frame members of any desired length which, when assembled with the corners, provide a door frame conforming to the required dimensions.

It is also an object of this invention to construct interchangeable standard end members for a. door frame which may be joined together by standard pieces of structural iron or steel out to suitable lengths to provide a doorway of the required dimen-,. sions; I I

It is furthermore an object of this invention to construct a door frame comprising standard corners, which may be connected by intermediate. members mounted flush therewith, whereby not only hinge members for the door are provided, but also a stop for the door when in closed position.

It is finally an object of this invention to construct a device whereby a door frame of practically any dimension may be easily built up and placed in position and anchored immovably in the building or structure to which it is attached.

The invention (in a preferred form) is illustrated in the drawings and'hereinafter more fully described.

In the drawing: Figure l is view of a double metal door mounted in a frame'embodying the principles of my invention, Fig. .Zis a perspective view of a single door mountedin a modified type of frame. embodying the principles of'my in vention. Fig, Sis'a top plan view partly broken away I tached to a building or other structure. Fig. is a section taken on line H of Fig. 3. Fig. 5 is a section on line;55 of Fig. 3, with parts in elevation. Fig. 6 is a section on linc'66 of Fig. 2,'with" parts omitted and with parts in elevation. Fig. is a fragmentary plan view of one extremity of one of theuniversal corners of a door frame. 4 I Fig. 7.

As shown in the drawings, the door frame shown in Fig. 1, comprises corner'meinbers .of angle section and denoted respectively by the reference numerals1,2, 3, and 4, each of said inembe'rsbeing substantially identicalfin construction and interchangeable withOthersthereof to a certainextent. However, of course, members 5, on each thereof,co mplete interchangeability is not permitted, as obviously the doors secured thereon must necessarily swing either from the left or right or the casing, and not from the top or bottom;

, 90 and 4, is provided on itsextremity was thereof. Each of said corner members 1, 2.

foffset portions, denoted by the reference numeral 6, togpermit fitting of an intermediate member 7 thereover to. join said corner pieces together and afford the sides and bottom of the door frame. members are provided'with a ledge or stop and top 8, against which thedoor 9, is adapted to rest when said. dooris closed, and likewise sald intermediate connecting members 7, are

.-' provided with similar ledges or stops 10,

a perspective of a door frame-shown unata Fig. 8 is a section on line 88 of owing to the hinge Said corner which, when the frame is set up, are in.

alinement with said stop 8. For the pur-l pose of firmly securing the corner members of the frame in the concrete or other material 11, ofthe structure in which the frame is mounted, lugs 12, are provided on the underside of said corner members and hooked in aperturestherein are L-anchor bolts 13. In the modification illustrated in Figs. and 6, the construction is substantially the same, except for the fact that instead of angle members provided with stops, the respective corner members, which may be denoted respectively'by the reference numerals 14, 15, l6, and 17, and intermediate members 18, are of Z-cross-section. As before, the

corner members of the door frame are pro- I vided with oflset portions 19, which permit an interfitting with the intermediate members 18. However, in this construction the stop is dispensed with, and instead the flanges 20, of the respective corner and intermediate members, serve to limit the inward movement of the doorQl. It is to be noted also, that in the embodiment of my invention shown in Fig. 2, the corner members l-l, and 15, are right angled, whereas the corner members 16, and 17, are straight, as it is sometimes not desired to extend the door frame across the threshold of the door. However, hinge members similar to the hinge members 6, are provided on the corner membersof the door frame and likewise anchor bolts 23, for the purpose of rigidly securing said members in place. I

The operation is thought to be obvious from the description. However, vhen it is desired to set up a door frame the respective intermediate members are cut to the required length, and the corner members are then joined to one another by said intermediate members, Which may be bolted 0r riveted thereto, as desired. lhe anchor bolts connected on thecorner members serve to secure the structure firmly in the concrete or brickwork in which the casing is mounted, I l

I have shown the hinge members as forming a part of the corner members, although this is not necessary, as obviously they may be formed as a part of the intermediate members.

Of course, the particular manner of joining the intermediate members to the corner members may be varied through a wide extent, as well as other details of construction, without departing from the principles of my invention. I therefore do not purpose limiting the patent granted otherwise than necessitated by-the prior art.

I claim as my invention:

1. A. door frame comprising corner members, intermediate members adapted to inter-fit therewith, door stops on said corner and intermediate members adapted to registor with one another, and means anchoring said corner members in a building structure.

2. In a device of the class described corner members, offset portions on the extremities thereof. intermediate members adapted to fit over said offset portions to lie flush with'the main portion of said corner members, means anchoring said corner members in the building structure, and door stops secured on said corner members and said intermediate members adapted to lie in proper alinement with one another. l

3. in a device of the class described corner members, intermediate members adapted to interfit therewith and join said corner members together, anchoring means pivoted to said corner members to be embedded in the building structure, and hinges on certain of said members to receive a door attached thereon,

4. A door frame comprising interchangeable corner members, intermediate members adapted to join the same together, offset portions on said corner members adapted to interfit with said intermediate members, and stops on said corner and intermediate members adapted to abut one another in alinement when said door frame is set up.

In a device of theclass described corner members, members similar in cross-section to said corner members adapted to interfit therewith to join the same together, hinged members on certain of saidmembers to permit a door to be attached thereon, and means on said corner and intermediate members to limit the movement of said door.

In testimony whereof I have hereunto FRANK K. HUDSON.
