lly invention has reference to 'commer application for Letters Patent of the United States filed May 19, 1925, SerialNo. 81269. The present=invention seeks to improve; the manner of consti'uctionand arrangement of such signs.

One of the objects thereof is to provide a sheet metal frame or moulding for the' sign which is formed of asingle sheet of metal, bent into the desired form, by which construction a frame of great strength may.

letter in which is beveled or otherwise turned out of the plane of the main sheet. This not only strengthens the edge of the plate, but when a backing plate for the letters is used, as shown in said former applicatlon, the turned edge of the letter bears against the. backing plate, forming a more rigid structure, and preventing anyrattling sound which might result from a loose contact of such parts. in some cases to form a flange on the edge of the letter by means of a strip fastened at an angle therewith by soldering or similar method, butthis method is aslow and expensive one.

The production of the letters in the manner mentioned in a simple and" inexpensive manner is made possible by means of a machine designed specially tor the purpose, and

the subject of a companion application for Letters Patent of the United States; ]By the use of this machine any style of letter or other character can be cut and formed by a,

continuous operation, or operations It has been the custom to cut out a letter with a cutting tool, comprising suitable dies and cutters, but each one. has been limited to the production of a singleletter', and a special type oit'letter, whereas in the use of said machine any desired style can be reproduced.

The above named, and other features and advantages of the invention will more fully appeartrom the following specification, ret? 'erence being had to the accompanying drawings, in which-;

i Fig; 2 is a" cross se'ction on' the broken line 2 20f Figl1;-' 1 Fig;- 3 is a cross-section ofth'emoulding 1, enlarged. f 3 f The reference number 1 indicates the up- Pfmouldingofa sheet-metal frame,- 2 the I lower moulding, and 3 one of the end pieces, properly joined with, the first-named: sections. The lower moulding is formed with a channel 1, for the support of the lower edges of any desired number of letter plates- 5, in rear of which is shown a backing plate 6, of frosted glass or similar material,

also supported in the channel'4." The upper edges otthe-plates 5 and'6 are held in a channel 7 formed on the inner side of the upper moulding 1. The-letters are formed bycutt-ing the same from the plate 5, as in dicated by the letter E in Fig. 1, the edges of theletter being bent inwardly at an-angle of approximately forty-five degrees, as

shown at '8, the inturned edges bearing against the outerface of the plate 6, and assisting in providmg the rigid construc-.

tion hereinbefore mentioned. 7 The mouldings are each provided back plate 9, bent forwardly into a cornice comprising a straight band '11 and curved,

portion 12, ending in a panel'13, formed at its lower edge into a looplt. In the case with at,

ofthe moulding 1 this loop, is'continued into the channel 7, the inner edge 15 of which'is turnedv upwardly. The edge 16 of the plate -9 is also turned upwardly, the turned edge thereof being enclosedwithin the loop 14,

and. adding strength to thejoint formed I thereby. I

' All of the parts above mentioned are integrally formed, such construction doing away with the necessity of riveting or otherwise connecting a number of separate parts,

as is now the custom;

The moulding 2 is formed moulding 1, except that the channel 7 is given a greater depth than that of the chan similarly to the l nel 1, so that the plates 5 and 6 can'be. first into the channel 41, without possibility of their release except by a reversal of the. operation.

The edge of the letters in the letterpl'ates can be bent so as to project at any desired angle with the main plate, including a right angle, or they can be" turned into ahead or other formation out of line with said plate. Thesebevels and other formations inserted in the channel 7, and then lowered are always produced integrally with v the plate, by a comparatively simpleoperation,

back plate having its lower edge turned up- I wardly against itself, anda cornice formed wintegrallyewith said back plate, andhaving I said back 'back plate and cornice formed integrally itsilgwer edge rolled round the lower edge'of plate. r 1 I 2.-Ai sheet metal frame, 7. comprising a What I claim, and desire to secure by therewith, andhaving its lower edge rolled round the lower edge of said back. late, and

a channel formedintegrally with the rolled edge of said cornice, and having-its inner edge turned upwardly upon, itself. 7

3, A sheet metall frame, comprising a back plate and cornicefonned integrally therewith, the lower edge of therback plate being turned upwardly upon itself, and the loweredge of the cornice being rolled upon the loweredge of the back plate, and a channel formed integrally with the rolled edge of i the cornice.
