STREET-SIGN.

SPECIFICATION forming part of Letters Patent No; 477,873, dated une 28, 1892. Application filed February 8, 1892. Serial No. 420,692. (No model.)

To all whom it may concern.-

Be it known that I, 'ENooH J. SHAW, of Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Street-Signs, of which thefollowing is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specificatiomin which Figure 1 is an elevation of a portion of an electric-light post, showing myimproved sign in position; Fig. 2, a top plan view of the sign-brackets, showing method of clamping to the post; Fig. 3, an elevation of the bracket detached; Fig. 4, a transverse section taken on line y y in Fig. 2; and Fig. 5, a View similar to that shown in Fig. 2, showing amodification in form of the bracket.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates especially to a device for securing street-signs to electric light or similar cylindrical posts; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operationof the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the post, and B C the clamp members. These members comprise an approximately semi-cylindrical strap d, the ends f of which are turned radially outward, forming clamping-arms. Radiating from each strap d there are three arms g h, the central arms It being of greater length than the companion arms g. Secured to each set of arms g it there is a sign-slide i, the ends of said slide on each bracket member terminating at j at the end of the arm h. Each bracket member as thus constructed is approximately triangularin top plan View. The outer edges is of the plates 41 are turned inwardly, forming lips for holding the sign m in position. The sign-plates m are inserted in the slidesz' through the ends j, this arrangement enabling the signs to be changed as frequently as desired; or instead of forming the slides i with the lips 7a the signs may be painted directly onto said slides.

The signs may be of transparent material, it desired, the radiating arms projecting said signs sufficiently far from the clamp or post not to interfere with the light showing through.

In use the bracket members B O are adjusted on the post A in the same horizontal plane With the straps d, in engagement with said post. Corresponding arms are secured together by a screw-bolt 19, onto which a thumb-nut q is turned. This clamps the parts securely onto the post and they can be adjusted readily, so that the signs are in parallelism with the street, respectively,which they indicate. Diametrioal'ly-opposite signs are presumed in this form to bear-the same imprint, so that they may be discerned from the street or sidewalk.

The form of the bracket shown in Fig. 5 is triangular in plan view for use Where three roads meet, the member B being in this form slightly larger than the member 0.

Having thus explained my invention, what I claim is In a sign-support, the post,in combination with the clamp members 13 0, having the areshaped straps d, provided with clamping-arms f, the nuts and bolts for locking the arms of opposite members together, the radiating supporting-arms on said straps, and the horizontally-arranged sign frames or slides i, secured to the outer ends of said armsfall being arranged to operate substantially as described.
