Patented May 24, 1932 UNITED STATES PATENT oFncE Application filed September 22, 1931.

My invention relates to the construction of trafiic signs such as are used at the intersections of streets and roads and has for its object, in part, to provide for a simple and secure interengagement between a supporting device, adapted to be secured to a post, and label frames adapted to carry labels with the street names. A further object of my invention is to provide a construction of label frame which will permit of the ready insertion and withdrawal of label plates and at the same time to securely hold the label plates in position while the frames are in use and my invention consists, in part, in the con- 16 struction of a supporting device in such manner as to provide for a secure interengagement of a label frame with it and, in part, in the construction of the label frame in such manner as to provide for its interen agement with the support and also to provi e for the insertion and replacement of label lates While, at the same time, providing for t e secure locking of the label plate in the'frame while the frame is in use.

The nature of my improvements will be best understood as described in connection with the drawings, in which Figure 1 is an elevation of a traffic sign embodying my improvements.

Figure 2 is a plan view of a similar traffic sign showing a somewhat different angular arrangement of the label frames.

Figure 3 is a sectional view taken as on the line 3-3 of Fig. 1, of the rectangular form of frame.

Fi re 4 is a front elevation of a label holding ame generally similar to the frames shown in Figs. 1 and 2, but showing an upward extension from the frame for holding an additional street sign.

Figure 5 is a plan view of the label holding frame shown in Fig. 4, the indication in dotted lines showin how the upper portions of the plates ma ing up the frame can be so arated for the insertion of label plates.

Figure 8 is an elevation showing the man- Serial No. 534,287.

ner in which the shank of the label holding frame is inserted in the supporting device, the supporting device being partly broken away to show its internal construction.

Figure 9 is a view generally similar to Fig. 8, showing the label frame in socketed position in the holder, the holder being shown in section through the slot into which the shank of the frame is inserted, and- Figure 10 is a view showing a modification of the supporting head construction,

A indicates the frame holding device when constructed for use as a cap piece on the end of a post, while A, Fig. 10, shows a modification of this holding device adapted for use, for instance, in connection with a trolley pole or the like. The cap piece indicated at can of course be set in any angular position on top of the post and should then of course be secured against angular deflection, which can, for instance, conveniently be done by a Set screw, indicated at B Where the holding device is to be attached to a pole it is conveniently made, as shown in Fig. 10, so that the holding device will fit against one 75 Side of the pole and be clamped to'it by a complementary casting B fitting on the other side of the pole and held to the socket piece proper as by bolts, indicated at B any other convenient fastening device can of course be used to secure the supporting member in an desired position. The supporting member or A is formed with slotted openings, indicated at C, and with upwardly and downwardly extending sockets at the inner end of the slotted openlng, as indicated at C a ledge being provided adjacent to the downwardly extending socket, as indicated at C to act as a support for a label frame inserted in theslot. A bolt hole D is conveniently provided, extending through the walls of the slot C and through one of these walls is made of such form and dimensions as to permit the head of a bolt inserted in the bolt hole to pass into contact with the shank of a label frame, as indicated at D The label frame indicated at E is provided with a shank E which is adapted to enter the slot 0 of the holding device but is of less height than the slot and the end of this shank is provided with upwardly and downwardly extending lugs, indicated at E and E, which are ada ted to enter the upper and lower sockets 1 and C of the holding head or device, the upwardly extending lug being of such len h th t it will project into the upper socket 1 when the shank of the frame rests upon the led e C and the downwardly extending lug is of such length that it will ass over the ledge C when the upper lug 1 is inserted in its socket and the shank moved up in the slot, as shown for instance in Fig. 8. The method of inserting the shank in the holding device is clearly indicated in this figure and it will be seen that when the parts have been assembled the shank and its label frame is supported in horizontal position and so interengaged with the holding device that it can only be removed by reversing the movement by which it is introduced into the slot and made to interengage with the upper and lower sockets.

The label holding frame as shown is made up of two plates F and F The shank E being formed integral with the frame plate F and the plate F, has its lower ed e and a ortion of its outer edge secured to t e plate in spaced relation to this plate by means of rivets, as indicated at G, blocks Gr being provided to properly space the plates making up the frame. This method of securing the plates F and F together enables their upper edges to be separated to a limited extent and I provide on the inside of the upper edges on one or both of the plates F and F inwardly extending lugs H, H, the upper edges of which are preferably made slanting as indicated at H. The plate F is provided with a shank extension as indicated at F adapted like the shank E of the plate F to extend into the slot of the holding device or head, as shown in Figs. 3 and 9. I indicates a label plate which is made of proper size to be inserted in the frame.

In operation the upper edges of the frame plates F and F are sprung apart, as indicated in Figs. 5 and 6, and a label plate or plates I is inserted between the plates into the space between the plates forming the frame, this insertion being {facilitated by the tapered form of the lugs The return of the frame plates F and F to normal position causes the lugs to extend over the tops of the label plates, thus lockirig them in the frame. The shanks E and 2 of the frame are then inserted in the slot C of the supporting head, the breadthof which is preferably such as will require the shanks to be pressed slightly toward each other in order to enter the slot and the lugs of the shank E are interengaged with the sockets in the manner indicated in Figs. 8 and 9. It will be seen that the interengagement of the shanks name-re of the frame plates in the slot of the holding device will effectually prevent the separation of the frame plates to such an extent as would permit the withdrawal of the label plate. It is also practicable with my construction to secure the label frame in the holding device before the insertion of the label plate in the frame by pressing the label plate down against the sloping surfaces of the lugs H to spring the upper portions of the plates constituting the label frame apart to a sufiicient extent to enable the label plate to be fully inserted, the spring of the frame plates after the insertion of the label plate, bringing the fingers H back over the top of the label late and the en agement of the shanks E and F in the slot, e ectually preventing such spreading apart of the frame plates as will permit the withdrawal of the label plate.

As a further precaution against the disengagement of the frame with its holding device and also as a means for clam ing the shank or shanks of the frame plates and F to one side of the slot in the holding device,

I provide a bolt J, which is inserted in the bolt holes formed in the walls of the slot and through a bolt hole formed in the shank or shanks of the frame and with its head J resting against the shank E and then by means of a nut J the bolt head J can be drawn against the shank and the label frame firmly secured in position in the hold in device.
