Patented Dec. 16, 1930 PATENT OFFICE UNITED STATES rRANors E. JJWILDE, or-M ADowMERE PARK, EW YORK ELECTRIC SIGN Application filed September 4, 1926. Serial No. 133,676.
This invention relates to What are known as talking signs. These signs heretofore have consisted of a bank of lamps arranged in the form of a horizontal panel, the lamps being flashed to carry the letters or other figures across the panel from right to left; Such signs necessarily require considerable space and for this reason are suited only to special locations.
An important object of this invention is to provide a talking sign yvhich will occupy less space than that required by the horizon- 'tal signs in use. This object is attained by providing the bank of lamps in a vertical panel and by traversing the lettersor other sign characters from the bottom to the top of the panel. 7
Afurther object of the invention is to utilize the panel for daylight display purposes, This object is attained by providing stationary sign characters on the panel which Will show in daylight and which will not interfere in any way with the traverse of the traveling sign characters.
Further objects of the invention are to provide improved mechanism for flashing the letters and to simplify and make entirely practical the mechanism for such purposes.
The novel features of construction, combinations and relations of parts by which all the foregoing and other desirable objects are attained are set forth in the following specification which includes as part of the same, the drawings wherein a concrete example of the invention is illustrated.
Figure 1 is a partial front elevation of one of'the new vertical sign panels, illustrating as best can be done, the vertical travel of the moving letters and the stationary letters appearing in the background, with the control mechanism shown at the side of the same. Figure 1a is a broken side view of a portion of the panel showing the stationary characters in raised outline on the face of the panel. Figure 2 is a broken front view illustrating how the background letters forming the sta-' tionary display for daylight purposes may be provided by equipping the lamps which are appropriately positioned to form the daylight let-ters'with special reflectors or the like which will cause these particular lamps to stand out by contrast with the other lamps in the banln Figure 3 is a broken side view showing two of these special reflector lamps and one of 65 the regular lamps of the bank.
Figure 4 is a broken detail illustrating the possibility of providing the daylight letters by specially shaped neon tubes overstanding. or otherwise arranged so as not to interfere with the regular moving sign lam s.
Figure 5 is a broken side view illustrating this latter possibility. v
Figure 6 is a broken part sectional view of the stack of moving sign characters, as viewed from the right in Figure 1.
Figure 7 is a sectional detail showing particularly the method of supporting and Withdrawing the individual characters. I
Figure 8 is a broken sectional detailacross the guideway for the chains and plates which shows at the left in Fig, 7.
As shown particularly in Figure 1,, the lamps 1 which by their flashing form the traveling letters, are mounted in suitably spaced relation on the face of a vertical panel 2 and are energized according to their locations to form the vertically traveling letters indicated at 3. v 6 I On theface of the vertical lamp panel, stationary letters are shown at 4 formed in such a Way as to appear in daylight or when the sign is illuminated by an outside source and designed, furthermore, so as not to interfere with the traveling sign letters.
In Figs. 1 and 1a the stationary characters 4 are indicated in raised outline on the face of the panel preferably painted in distinguishing color from the panel soas to be readily readable in the daytime, when the traveling letters are not in operation. At night, the letters traveling u the signboard illuminate these stationary ackgroundletters and provide an additional point. of in terest. In the daytime, of course, the stationary letters alone will appear and these give the sign a daylight advertisin value.
Another wa of providing the xed day.- light display 0 aracters is illustrated in Figures 2 and 3 by painting or coating the, back when the flashing lamps are inactive.
The traveling letters are produced by flashing mechanism similar in a general way to that disclosed in my Patents 1,591,917, 1,626,899 and 1,626,900 and comprising sign characters!) of different letter shapes mounted on plates 10, stacked in a vertical holder 11. These sign characters are engaged and withdrawn one at a time from the bottom of the stack by traveling chains 12 which traverse the bottom 'of the stack and serve to strip off the sign plates one at a time and to' carry them up through a bank of switch contacts indicated generally at 13. The contacts of this bank are individually connected to the correspondingly located lamps' in the. lamp bank and are selectively actuated, according to their position by the differently shaped characters. I
The sign characters are shown as passing from the foot of the stack through a horizontal guideway 14 to an octagon shaped pulley,15, the sides of which substantially correspond each to the length of one sign plate and which acts to carry the plates and propelling chains around the corner to the vertical section 16 of the guiding structure.
After the sign characters pass upwardly through the control bank they are carried to the rear over another octagonal pulley 17 and rearwardly extending guideway 18 from which they fall into a reversing chute 19 which turns them over as shown at 10a, 10b, and drops them letter-side down onto the top of the stack in the vertical receiver 11. The chains are shown as passing over suitable guide sprockets 20 at-the top and in rear of the reversing chute and downwardly over sprockets 21 driven by motor 22. A take-up sprocket is indicated at 23 adjustable to remove undesired slack.
The lower horizontal reaches of the chains are shown as sliding over rails or tracks 24. To minimize friction where the weight of the stack-comes on the chains, sprockets 25 may be provided, these serving as rolling supports over which the chains travel with a minimum of friction. These sprockets turn-- ing with the chains are utilized to drive the sprockets shown at 26 in Figure 6 for positively feeding the plates down in the stack.
To permit extra plates being readily ad 1- ed to the top of the stack, the upper ends of the corner strips 35 may be bent outwardly as at 40 in Figure 1 at a point just below the reversing chute. This leaves a small portion at the top of the stack open to the rear so that plates may be readily added to or taken off the top of the stack without unfastening the corner strips.
Suitable interlocking connections are prorided between the chains and plates, the same automatically engaging as the chains pass beneath the foot of the stack to enable, the chains to carry off the lowermost plate. In the illustration such interlocking means consist of spaced pins 45 on the chains projecting inwardly in opposition and adapted to engage behind the ribs or runners 44, Fig. 8 on the edges of the plates. These pins, it will be seen, carry the plates from the foot of the stack through the horizontal Way 14. remain engaged with the plates in the travel of the same with the first octagonal pulley and during the travel up past the switch contacts, over the upper; octagonal pulley and through the return way 18 to the reversing chute.
The movement of the plates, therefore, is
positive and assured, making the travel of the flashing letters constant and even from the bottom to the ,top of the vertical panel.
This feature of traversing the letters vertically is an attraction in itself, holding the observers attention and adding to the intrinsic value of the sign. When the moving letters are not in use, the stationary letters give an advertising value to the sign so that actually the sign has full value at all times. The stationary letters may be illuminated at the same time or alternately with the moving letters, for instance, where the stationary letters are formed by reflector lamps as in Figures 2 and 3 these special letter-forming lamps may be flashed or be allowed to remain on for any desired period following a certain cycle of the talking letters. The
stationary letters formed by the neon tubes also may be illuminated constantly or intermittently, following some definite, or indefinite cycle accordlng to the effects desired.
The spring support at the foot of the stack and the rolling supports for the chains at this point cushion the dropping action of the plates and reduce the friction so that only relatively small power is required to operate the control mechanism. The feed sprockets 26 afford a positive downward feed of the plates and also act in the nature of movable supports temporarily carrying the weight of the stack above a certain number of plates v at the bottom of the stack. This supporting of the main body of the plates is important because the weight of the plates resting on the chain can thereby be reduced to the point where only very little energy is required to draw out the bottom plate and the action thereby becomes smoother, easier and quieter.
It will be evident that various changes may be made in the structure without departure from the true spirit and broad scope of the invention. The stationary letters, for instance, instead of being fixed and immovable, may be made changeable, in the nature of stencils or the like.
What is claimed is:
In a talking sign, a panel of travelingletter-forming lamps, means carried by sald panel for forming stationary letters visible independently of the traveling letters and means for flashing the lamps to effect traveling of design sign characters over the panel,
the stationary letter-forming means com-' prising appropriately shaped neon tubes supported on the panel in the same field but clear of the traveling letter-forming lamps.
In witness whereof, I have hereunto set my hand this 11th day of August, 1926.
FRANCIS E. J. WILDE.
