This invention relates to an interchangeable sign more particularly intended for use as a high way sign. 7 v The principal object of the invention is to pro vide a sign construction which can be quickly and easily assembled at the time of erection to give any desired indication or information and which, when assembled, will‘ securely lock itscomponent O parts together to prevent unauthorized tampering. clamp the entire assemble in place. The bolts l6 clamp‘ the back plates l4 and I5 tightly against the tongues 13 to lock the letters in position andv to prevent unauthorized removal thereof. The extremity of the bolt It may be riveted into 5 its nut to prevent removal of the bolts. ' In the usual installation, the perforations H in the face ll! are allowed to remain‘ exposed, as shown in' Fig. 1. If desired, however, the face -may be painted with a thick viscous paint which 10 Other objects and advantages reside in the de will ?ow into and ?ll the perforations, leaving. a tail construction of the invention, which is .de signed for simplicity, economy, and ef?ciency. ‘ substantially smooth back ground surface, as2 shown at [9, in Fig. 6. , . _ ' These will become more apparent from the fol The letters maybe made any desired heighth. lowing description.

' V vThe invention comprises a perforated front sign plate It), the entire surface of which contains-per forations I I regularly spaced over itsv surface. The letters of the sign, indicated at 12, are pref? 35 erably formed of sheet metal with rearwardly ex tending ears l3 spaced so as to enter the spaced perforations ll. ' ' ' They could, however, be one or more spaces as desired. v The rear of the sign is closed by means‘ of two back plates I4 and IS. The outer extremities of 4 O the plates“ and I5 are bent to form hook. like edges which enclose the side edges of the front plate, Ill as shown at Hi. ' While a speci?c form of the improvement has been described and illustrated herein, it is de 20 sired to be understood ‘that the same may be varied, within the scope of the appended claims,v without departing from the spirit of the invention. ' - Having thus described theinvention, what 'is claimed desired secured by Letters Patent is,:- .257 1. An interchangeable sign comprising: a per forated face plate; metal letter members; tongues formed integrally with said letter members and - projecting rearwardly from said letter members through the perforations in said face plate; a 30 backing plate secured to said face plate; and means for drawing said backing plate against said face plate to clamp said tongues againstthe latter. 2. An interchangeable sign comprising: a per 35 forated face plate; letter members; tongues pro- . jecting rearwardly from said letter members through the perforations in said face plate; a backing plate; a hooked edge on said’ backing plate for enclosing the edge of said face plate; 40 and means for clamping said backing plate against said face plate so as to lock said tongues ‘ The inner extremities of the plates l4 and ‘I5 in place therein. V 3. An interchangeable sign comprising: a per overlap each other as shown in Fig. 2, so that at tachment bolts l6 may be passed through all three ‘ ,forated face plate; letter members; tongues pro- 45 ' plates to attach the sign to a supporting post or jecting rearwardly from said letter members through the perforations in said face plate; a pair standard [8 as illustrated. . The sign is formed by selecting vthe desired of backing plates; hooked edges on said backing‘ letters and passing the tongues l3 through the plate for engaging the side edges of said face plate, . ‘ perforations to give the desired letter spacing and saidbacking plates overlapping each other; and 50' arrangement. The tongues are then bent down- ‘ clamping means for clamping the overlapped edges of said backing plate to the back of said face wardly as shown in Fig. 4. , The plates l4 and [5 are hooked ‘over the edges plate. ‘:7 j of the plate "I and the bolts l6 are tightened to ' y ROYAL A.
