UNITED STATES THEODOR 0. JORGENSEN, 0F BETHLE-IEM, PENNSYLVANIA.

SIGN.

Application filed January 30, 1920.

To all w hom t may concern:

Be it known that l, THnoDoR 0. JORGEN- sun, a citizen of Denmark, residing at Bet lehein, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful lmprovements in Signs, of which the following is a specification.

rlhis invention relates to signs and more especially to changeable signs which are' capable of forming every letter of the alphabet.

The principal object of the invention is to produce simple and eiicient means for quickly changing to the desired letter.

Another obj ect of the invention is to provide means whereby the sign may be non mally and automatically changed to a blank.

In order to carry out the above and other objects, I provide a sign board of rectangular construction having aplurality of shutters hingedly mounted upon one surface of the board so as to outline the various elements of all the letters of the alphabet, one face of the shutters being colored the same as the sign board and the other side being colored so as to sharply contrast with the sign board. Such an arrangement would, ofcourse, be very complicated to operate so I provide contact panels corresponding to the letters of the alphabet for changing from one letter to another in a manner to be hereinafter described.

One embodiment of my invention is shown in the accompanying drawings, where Figure 1 is a plan view of the sign board showing the letter R outlined thereon.

Fig. 2V is a plan view of the sign board showing the same blank..

Figs. 3 and d are sections taken on lines 414-11 and 3-3, respectively, of Fig. 2;

Fig. 5 is a fragmentary side elevation partly in section of my invention.

Fig. 6 is` a fragmentary topplan view of my invention, and

Fig. 7 is a fragmentary detail perspective of the pulley arrangement used with each shutter.

As shown in the drawing, my improved device is composed of the sign board 1 which l shall first describe generally. Upon the sign board 1 there is mounted a plurality of shutters which are arranged to conform with all the common elements in the various letters ofthe alphabet. There is provided the pair of elongated horizontal upper shut- Specication of Letters Patent.

Serial No. 355,151.

ters 2 and the small horizontal shutters 3 which lie alongside the shutters' 2. Similar shutters `6 and 7 are provided upon the lower portion of the sign board. A pairvof upper vertical shutters l and a pair of lower vertical shutters 5 are provided so as to connect approximately the extremities of the hori- Zontal shutters l and a `pair of lower vertical shutters 5 are provided so as to connect approximately the extremities of the horizont-al shutters 2 and 6. Centrally located vertical shutters 8 and 9 extend so as to connect the middle portions ofthe shutters 2 and 6. Between the shutters- 8 and 9 a semi-circular shutter 8 is provided. A pair of upper and lower diagonal shutters 11 and 10 are provided so as to radiate from the semicircular shutter 8 and to terminate at the inner section of the shutters 2,1ex tending at right angles to the vertically centrally'located shutters 8. lt should bewunderstood that one side of these shutters is colored similar to the sign board whereas the other side is colored so as tor contrast therewith, so that when the contrasted colored side is showing, an outline of various `letters of the alphabet may be made in a manner to be hereinafter described.

`By referring especially to Fig. 3 it will be noted that the shutter 5. comprises two leaves. One leaf 18 is fixedly attached to the sign board 1 by means of the screws 19 and is provided with a sleeve 16. The sleeve 16 is also provided with its leaves so that the leaves 5 and 18 may be hingedly connected to each other by means of the pins 17. In order to operate the shutter 5, there is situated thereon a staple lll which eX- tends from each surface so as to receive the eyes 15 which are in turn connected to the pulleys 21. One cord 2O is used to place the shutter 5 in a closed or blank position while the other cord 39 is used to swing the shutter 5 in an open o r indicating position. These cords 2U and 39 pass through the apertures 13 provided in the sign board 1. Now d, it will be seen that the shutter which in turn is provided with the sleeves and a pin for hingedly mounting the shutter 2. All the shutters are operated in a similar'manner, so that if the operation of one is known, the others will be clearly understood. p

`By referring to Sheet 2 of the drawing,

wherein is illustrated the operating means used to move the shutters, it will be seen that the cord 39 passes over the pulley 50 which is carried upon the shaft l0 which is connected to the eye 2S or' the lever 25. lever 25 is mounted upon a ulcrum 2G and has a right angularly extending arm 27 extending from its central position. VThe cordf20 extends over the pulley 2l and the pulley 22 which is mounted upon the shalt 4:1 and is inserted through the lower eye 28 and iixedly attached to the lower end of the lever 25 in any suitable manner. An extension 29 of the cord 20 passes beyond the eye 28 andV is connected to 'the coil spring 30 which in turn is attached to a bolt 3l which passes through any suitable support 33 and is rixedly attached thereto by means of a nut.

A pair ol drums 3ftare situated upon the shafts 35 behind the lever 25 so as to be in substantially the same plane as thearm 27. A belt 33 is mounted upon the drum 34 and is provided with a plurality of contact panelsV 36 from which extend a plurality oi .fingers 37 for engaging the arms 27. Each of the panels 36 will designate a letter of the alphabet and therefore will be provided withthe necessary ngers 37 to engage the necessary arms 27 for operating the necessary shutters to make the outline of the desired letter. f

rlhe letter which the panel represents should, vof course,v be placed upon the panel and this panel will be brought adjacent the arms 27 so that the fingers 37Vwill engage the same and the drums will then be operated or rotated in any suitable manner so as to torce the arms 27 to take the position shown in dotted lines in Fig. 5, whereby the lever 25 will be operated so as to' pull upon thercord 39 which in turn will swing the shutter to its designating position.

Y Vif-hen it is desired to have the sign board blank, it will be readily seen that all that is necessary is to rotate the drums so Vas to place the lingers 37 out of engagementl with the arms 27V so as to allow the coil springs 3,0 to return the lever 25- to its normal position. v Y

It will bereadily understood that my device may be put to various uses; for example the sign may consist of a plurality of the boards 1 so'as to form words of any length and it will also be seen that the drums 34 may be operated so that diderent words may be shown upon the whole board consisting of a plurality of the sign boards l, if so desired, by arranging the panels 36 upon the belt 38. Y

F rom the foregoing description, taken in connection with the drawings, the advantages of the construction and the method of operation will be lreadily apparent to those skilled in the art to which this invention pertains, and while l have described the principle and operation of the invention, together with the device which l now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope o the appended claims.
