METAL DOQR OF? PANEL FOR LOCKERS AND THE LiKE.

To all whom it may concer-a.-

Beit known that I, RICHARD W. Jnrrs'nrs, oi Merchantyille, county of Camden, and State of New Jersey, have invented an Improvement in Metal Doors or Panels for Locle ers and the Like, of which the following is a specification.

' It is one of the objects of my invention to lighten the construction of metal doors or panels, such as are commonly used in metal lockers, without sacrificing the necessary strength and rigidity. To this end I dispense with the heavy angle-irons which have usually been used for the outer framework and-'form the frame of ilattened-U-shaped pieces of sheet metal. By bending one of the edges of these pieces into longitudinal angular flanges I provide longitudinal strengthening-ribs which enable the use of comparatively light metal without'sacriiice olf strength and rigidity. The web or panel sheet is ritted to these frames by placingits edges in the open side of their U-shaped bends.

In the drawings, Figure 1 is a front eleva tion of the metal framework of the door or panel., omitting the wall or web carried thereby. Fig. 2 is a vertical section of the saine on the line A A or' Fig. 1, on an enlarged scale and including the Wall or web. Fig. 3 is a horizontal section on the line B B of Fig. 2. Fig. 4 is a perspective view of a portion of the door or panel looking from the iront. v Fig. 5

is a sinn ar view looking 4llrom the back; and Figo is a perspective view of ners of the cross-bars. ,f

This sheet, cut to the proper size, is placed with its side edges itting in the U-shaped side members a a. The top and bottom cross-bars are then placed over the ends oi' the side bars o c and the top and bottom edges of' the sheet c and are riveted or otherwise fastened, as at c', to the members b l). The outer edges of the sheet care thus fitted within the flattened-U- Specicaton o Letters Yatent. lipplidation tiled Beeem'ber 8, 1905. Serial No. 290,892.

I prefer to cut oilq the inner portions oi top and bottom cross-bars b b at the corners, as shown at d, so that the inner portions of the side bars a (L at the corners may fit into the openings d 'thus afforded, allowing the strengthening ribs or flanges a to extend across the inner sides .of the cross-bars to the full length of the door or panel. These ribs or ancres a act as strengthening-ribs to im- C C C part strength and rigidity to the frame structure and ermit lighter metal to be used for the outer ramework than would otherwise be possible. frame.

rIhe rivets c', which secure the members a a l) b together at the corners, also serve to fasten the sheet c in place, and ordinarily rivets or other iastenings for securing the edges of the web in the U-bends of the frame-pieces .will not be necessary. Such `fastenings may, however, be employed, if desired, and in Fig. 5 I have shown a lip f cut in the inner portion of the side bar a and forced into engagement With the web c; but ordinarily the members a a b l) may be fitted suiiciently tightly on the' edges of the web c to render such iastenings unnecessary.

A middle or lock bar e may be secured to the side bars ri a. I have shown it with its ends inserted in the ,U-shaped o enings with the edges of .the web and rivete to the bars a c.

What I claim as new, and desire to secure by Letters Patent, is as follows:

l. A metal door or panel for lockers and the like, consisting of an outer frame formed of iattened-U-shaped pieces ol sheet metal- `united at the corners, and a panel web or sheet, carried by said outer frame and having its outer edges itting in the inner open edges of said U-sha ed pieces.
