METAL DOOR-FRAME.

Specification of Letters Patent. Patented Jan. 1?, 1911.

Original application filed Fehruary 23, 1910, Serial No/MWLBI. Divided and this application filed June 7,

1910. Serial No. 565,629.

To all whom it may concern:

' Be it known'that I, ENooH Onnsrnann, a resident of Syracuse, in the county of Onondaga and State of New York, have in- .5 vented a new and useful Improvement in Metal Door-Frames; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to metal door-frames,

and'the present a plication is a division of the application led by me Feb. 23, 1910, Serial No.-,-545,491. i

The object of my invention is to provide a metal door-frame in which the arts are so interlocked as to forin. practical y an integral structure and to do away with fastening'de'vice's in the way of rivets and screws, the parts being so held together as to prevent their working loose and so marring-the appearance of the doorway. i

To. these ends my invention comprises the novel features hereinafter set forth and claimed.

Referring to the drawings, Figurel is a 2.5 face view. of .adoorway embodying my invention; Fig. 2 is an enlarged section on" the line 24-2. Fig. 1; Fig. 3 is a perspective view of! the casing partly broken away; Fig. 4 is a section on the line 4 l Fig. 1; and

3;) Fig. 5is a perspective view of the manner of securing the trims at the top.

In the drawings the numeral 2 designates the door which ma he formed panels and slides in the rails being united in any suitable manner.

' he frame 3 is composed of sheet-metal of the proper gage to give the necessary strength and rigidity; This frame is shaped to. form the recesses i and the inwardly ex- 4o tending flanges 5. The metal trims 6 are secured to the frame 3, said trims having the inwardly extending flanges 7. These flanges are out .at intervals to form the lugs 8 which are bent to engage the shoulders 9 'on the frame 3. The flanges 7 of the trims '6 are further out at intervals and bent to form hooked lugs 6 The trims 10 are provided with the inwardly extending flanges ll which have formed at intervals thereon The trims lO are brought into interlocking engagement with the trials 6 by slipping said trims 10 over the hooks of metal, the

I 6" of the trims 6, said hooks passingthrough the openings 12. a The outer ends of the trims 10' are also provided with the inwardly projecting flanges 13 which engage the vertical strips 14 riveted or otherwise strips 14 are slightly off-set as at 15 to permit flanges 13 of the trims readily slipping hold said trim against outward movement. The horizontal trim 16 at the top of the dooi'way is secured to the frame 3 in the same manner as the trim 6 and accordingly said trim is provided with the flangev 17 with the lugs 18 which are bent to engage the shoulders 19. The trim 16 is further provided with the hooked lugs 20 which are adapted to enter the openings 9.1- of the trim 22. The strip. 23 is secured to the frame 3.

secured to the flanges 5 on the frame 3. The" into engagement with said strips so as to- I provide an inter-- once interlocked they are securely held in place and that too without the means of rivets or other fastening. devices which are liable to work loose and so mar the appearance of the doorway.

What I claim is:

1'. In a doorway the combination of a frame, atrim having portions bent to engage said frame, and a second trim having an interlocking connection with said first trim and engaging said frame.

2. In a doorway, the combination of a frame having shoulders, a trim having portions bent to engage said shoulders, hooked portions on said, trim, and a second trim having openings engaged by said hooked portionsjand engaging saidframe. I

In a doorway, the combination of a frame, a trim having portions bent to engage said frame,a second trim engaging said first trim, a strip on said frame engaged by said second trim.

In testimony whereof, I the said ENOCH OHNSTRAND have hereunto set my hand.

' ENOCH OHNSTRAND.
