frame It), as shown in'Figs, -1 to-3,-is comprised of '455p1ate r la v ly. Stif amplefrictionallen a er a T-section strap ll having-a center flange; The frame I0 is very stron and-isformed-very simply. by mitering out the center flangeatthe' points where the strap I I is bent to form the rectangua mentJby'the' plat Zllfancl the strap's'tfwiththie pole 311 is-insured to maintain; the sign .in its desired positiomon the 'pole'qj At the same time, thepla'teQllf-being held between the straps 3 I, and

lar frame Hi, the ends of the strap l I being welded the pole- 30;affdrd's' ample lateral supportfo the together by the-weld l2,*-as-"shown in Figs. 1 and 3. With the frame I!) thus formed, it will be provided with a top flange l3, bottom flange 14, front flange l5, and. back, flange I 6. As shown most frame It to *preventits being turned; with the back side l9 of theframe as an approximate axis, on the pole 30.

From the foregoing it is apparent that the clearly in Fig. 3, however, the back flange I6 does p ng p at 20, when Spre w l y ma ntain the ill under tension. Thus, if the straps 3! are stretched or otherwise slightly loosened by wind loads, for example, the plate 20 will take up any slack in the straps 3| and maintain the straps 3| tight around the pole 30. The spring plate 2|] will perform its function of tensioning the fastening strap on a pole or post of any configuration except where the curvature of the pole is identical with the natural set of the springplate. This contingency may ,be

avoided, howeverfbyreveifsing thegflcurvatureof the plate shown in thedrawin'gsor by'making the plate 20 of an irregular configuration.

It is also apparent from theforegoing, thatthe frame I 0 may be mounted in a horizontal position on substantially any type of vertical post. If the post is tapered, one of the fastem'ng'straps will simply be tensioned less than the other; If

the post is fluted, the edges of the plate 20 will either be mechanically engaged in the flutingsplate being spaced from each other when said tions of adjacent surfaces of the post and spring lfiii-spring plate is unstressed, and a fastening strap or restnpon the unfluted surface of, the post in thesame manner in which it rests face of an unfluted post.

p n the s Itis obvious that for stability preferably-two fastening straps, rather than one, are employed to mount the frame 10 on a post; Insofar: as the circumference of a postwill accommodate a plue.

rality of post plates and; fastening means for the 'fastening'straps, any number of signs may be fastened byone or a pair of fastening straps.- A preferredmanner of mounting tWo'signs-on one post, -however, isj shown in Figs. 1 and2. By;

employing a common fastening strap 3| which" passes through the upper fastening Istrapopening in one signiand the lower strap-opening in the other sign, each sign; thus may be furthersecured bya separate strap carrying a portion of the load imposed by only one sign. "'Thisman-L' ner of securing two signs xto'one post is obviously more economical than employing 'a separate pair of fastening straps e ually secure Another modification of for a single sign plate, thatis, a sign plate car-' rying printing on both sides. As shown'in FigsJ and has been found to be my: sign frame, as 1 shown in Figs. 4 and 5, is'particularly designed 4 and 5, thefrarnedlll is'compri'sed ofa fiat strap HI bentinto a rectangular form and butt welded at the baclg s'ideHQdf the' frame. spring plate is welded 'or otherwise secured to the frame H0 in the same'manner as the spring platen" is secured to the frame ;lll. 'Lugs H5 and Bare welded or otherwisesecure'dto f the j inside of the front and back sides of the frame H0. It should be noted that these lugs are oppositely offset in a clockwise direction from, the vertical center'plane of the frame.- Thus,

when thesign plate I22 is secured in the frame, it lies inthe vertical center plane of the frame and only a right-hand end ,portionof each jfacef of the sign plate will be obscured by a lug I IE or H6. Consequently, only the least important end v of astreet' sign, for example, will be obscured'by the fastening lug;

From the foregoing, it is apparent. that either modification of my sign frame affords,a. project ing rim which protects the edges of the sign plate from injury and that there are a of recesses and crevices for the collectionflof moisturev which would promote corrosion,-

and over said" spring plate. a 1nd. sign, apost, a sign frame, a laterally exextending around said post, through said frame tending spring plate integral with said sign frame "and eng agi'ng said post, said spring plate having a curvature incongruent with said post, portions of adjacentfsurf aces of the post and spring plate being spaced from each other when said spring plateis unstressed, a fastening strap extending around said post and connected with said sign frame, and adjustable fastening means to tighten saidstraparound said post andhold said spring plate 'ina deflected position against said post.

3. In a sign, a post, afirst sign, frame, a spring plate integral with said frame, a second sign frame, a;spring plate integral with said second frame said spring plates havingacurvature incongruent :with the periphery of said post, a common strap extending around said post and ex-;

tending oversaidspring plates and through said first and second sign frames, and adjustable securing means to tighten said strap around said post; and holdsaid spring plates in a deflected position;

in claim 1 comprising avsubstantially. planar sign frame, a spring plate extending laterally from the plane of said frame, a side of said frame to be adjacent the post to which said frame is to be secured, said spring plate being integral with said side and curved to provide a surface incongruent with the surface of'the post when the plate is unstressed,- whereby a strap passed around said post and over said laterally extending spring plate will stress said plate in a curvature more congruent with the surface of the post to take up stretching of the strap and. provide lateral support for'fthe" signi frame when the strap .is tightenedrt.

5. A sign for use in the combination as-defined in claiml comprising a'sign frame comprised of a metal strap having a T-section and formed into a rectangle having an inwardly directed central flange along three sides, the'fourth side being Ladapted to be secured tothe'post, a spring plate integralw'i'th the fourth side of the sign frame and extending laterally of the plane of' the frame, saidspring plate being curved toa substantially cylindrical surface incongr'uent with the surface 0f the post to which the sign frame is to be attached, whereby said spring plate will be stressed and provide lateralsupport for the sign frame when a strap is tightened around the post and the fourth side of the sign frame.
