T 0 all whom t may concern:

Be it known tirati, SIMON E. liAonns'rnoM, a subject of the King of Sweden, residing at Chicago, in the county o Cook vand State of Illinois, have invented. certain new and of which the following is e speciiicaion.

Thisinvenion reles to improvements in doors constructed from sheet metal.

The especial object of *die improvements embodied in this appliceion for patent is to roduce a door or similar stru-cime from ns ew pieces of sheet metal as possible consistent with strength and appearance of the finished product and one in which no loolis or 'rivets are required to hold ehe parts 1o- A further objeci'J is e6/produce e. vslieel metal door tliaifcen be cheaply nie'nnfeo iured and having' but few joints $0 oe closed.

in the accompanying drawing which forms a pari of this appliceiom l" lieve shown so much of a slieei,V metal door es isnecessary to illustrate ilie eenree of con struction which enter ino my inrentioniin' the ollowing views.

Figure l is an elevation of n. door ,constructed according to my invention; Fie. 2 is a cross section on an enlarged scale ieientluougli the center of lle door; Fig. is ev cross-section of one of lie sheet metal 'plaies forming a. larger perto my improved derni,v and Fig. Ais :i cross-seeion oi the comple nie-mary plete cr separare panel member of my-Limproved door.

Referring to the details of .lie drawing, 5 5 represent the Stiles of my improved the bottom of the door and being'of identical construction. A

6 represents the anel on one side of the door, 7 the bottom rail, 7 the top rail., Ortliepnnel on the opposite sideof 4olie door, and 9 channel bars which extend from thetop of the door to the bottom of same on opposite ln forming the Stiles 5 and the panel 6. I take a single sheet of metal of the desired size and bend the longitudinal edges to form tbe inwardly (intending fianges 5a. lf then Speeceton of Leitern' iraient.

sides of which are'spaccd epert the dieienceV required to provide'tlie hicliness of ne nished door. The slieet is then doubled upon itself to'erzn the inturned ienges 5c which are opposie the iengee '.ilie remaining portion'of the sheerl forme @enel S sind is offset from the piene o "lie 'seiles 5 as clearly indicated in iig-ign il eeneiinerm ber 8 is *formed ii'roin c sin@ metal the longiindinni nent inwardly. loiorin c ininrned franges 8 which when the parte are assembled ini/erlcclr with inlie flanges 5a.

The menibers, 8, and 8, ere heldin their assembled @tion and the eniire structure tend the lnll -lengh o3? faire door. @ne of the iegso'.' lie channel iie snugly `1between tlie ienge 5c :incline egfznosi'e Well of the 'stile 5 While tlie other es .of ille che-.nneiv resin 'egains lie panel wiili sufficient pres sureo hold ine panel 8 in closeengegement with the inturned dax/ige 5a. The por'aions of sheet metal bearing on the channel are thus spot `7welded" so es to maintain them in heir assembled relation. The .rails 7, 7, are formed from plein pieces of sheet meel which are arreng'eeiwih their edges ttin the oner corners of? the anges 5, 5, ang

nre welded in position. The openings-nt the l een endg bottom of lle door maybe lled in any de red manner known vin -lie' ariJ such forming no necessary part of nlyv invention. i

in aeseinbling a door from the' members deseribeli, elle panel 8 will be slid into position with its ienges'l in close engagementwith the flanges 5a and the channel bers 9 Will then be' pushed into. place endwise andv when in position the contiguous parte will be welded logether. The-rail pieces?, Y, lwill' eilen be out on and welded in place.

The Ine-nner of securing? the rail members. in place may bqwaried the seme constituting` no perto myinvention 'roper.

it -will beepparent t at in :i door con-` struct/ed as described there can be no leiserall)7 relative expansion between the Stiles and that tle opposed wells the panels endstiles will be rigidly ineinieine by hechennels 9.

Having abus deswibvd my ix'n'mlbinn what I claim ns'iiew, ist-- A den? Composed of Stiles and u singe pane-,i formed 'from a sirifgie piece of sheet metal, :a .secondpunei fermer] from e single piece of sheet metal having its edges in in "rocking engagement-With the edges o' the Stiles of die first membe and. channel bars having iiiarloeking engagement with the l first member and secured to the inner Su'r- 1 f( e of the second member, adjacent the inte 'locked portions of said iriembers,

In testimony whereof I affix my signature in ih@ presence of two Witnesses.
