Patented June 24, 1930 JOHN E. LONG, F MULTNOMAHyOREGON SWITCH CONTROL FOR AUXILIARY DEVICES Continuation of application Serial No.'212,75 5, filed August 13, 1927. This application iiled April 26;

1928. Serial My invention relates to control apparatus for electric circuits generally, such as is described in United States re-issued Patent No. 16,809, granted December 6, 1927, to myself and entitled Electric circuit control apparatus and is a continuationof the United States application filed August 13, 1927, by myself, Serial No. 212,755, and entitled Electric devices for display.

The principal object of my present application is to provide means for controlling an electric sign and auxiliary devices by the same perforated control tape, the latter being provided with apertures of the same size and spacing for. effecting such control,

thus adapting such tape to have all of the perforations made by the same perforating machine, or instrumentality.

More specifically, the object of my inven= tion is to provide control means of this character by which small, round, spaced perforations are adapted to produce a' continuous or a flash operation of such auxiliary devices without the use of an alternating switch.

as spaced.

Such objects are attained by spacing the terminals in the control apparatus with which such perforations register so that one or more of the perforations. in the com- 3 mon tape are in contact with the terminals for such auxiliary device at all times when the'control perforations pass over such terminals even though the perforations themselves are quite small and relatively widely The principal advantage gained by a control of this character is'that small holes arranged in the tape do not'wea'ken the latter unduly, and being relatively small, do not permit mercury or other electrically conducting fluid to pass therethru and force the tape away from the surface of the control element, which it slidingly engages.

The details of construction and the mode of operation of suchdevice are hereinafter described with reference to the accompanying drawings: in which,

Fig. 1 is a diagrammatic illustration of such control device;

Fig. 2 isa diagrammatic plan View of the terminals arranged in such control apparatus; and

Fig. 3 is a plan view of the control tape which makes-and-breaks connection with such terminals.

My improved control apparatus comprisesa container 1 having one wall portion, preferably the bottom 2, made of insulating material in which a number of terminals 3 are arranged in predetermined pattern. As shown in Fig. 2, such terminals are arranged in a plurality of longitudinal'rows and are uniformly spaced in such rows. The letters to be visibly shown upon the electric sign 4: are perforated upon the tape 5, as shown in Fig. 3, in a manner similar to the terminal arrangement in the container 1, and thus are adapted to register with th'e'terminals. r

Suchtape 5 preferably is arranged in end-. lessform, as'shown in Fig. 1, and operating devices v6 move the latter thru the container 1 to make-and-break contact between such terminals 3 and the electrically conductive liquid 1 within such container. Circuit is made thru battery 7, wire 8, liquid 1*, a selected terminal 3, wire 9,electric light 10 and return wire 11 to the battery 7. Reference is had to such re-issue patent'as to further details of operation and construction.

When it is desired to operate auxiliary devices by such electric circuit control apparatus without interfering with the main operation thereof, it is common to arrange perforations at the sides of thetape 5.

' Heretofore, the length of time which such auxiliary devices are to be actuated has been controlled by the longitudinal dimensions-of such perforations, or if an alternating switch is used, by the spacing between successive perforations. The use ofperforations of substantial size interferes with the operation of such electric circuit control apparatusby permitting the electrically conductive liquid to enter thru such larger perforations and to lift the tape from the terminals. The use'of relatively large perforations also weakens such tape unduly thus requiring such tape to be repaired or replaced frequently.

To effect the intermittent actuation of the auxiliary device 12, shown as a spotlight, I provide a series of spaced terminals 13 also arranged in longitudinal rows, such rows 1 being spaced the same as the spacing be- 12 can be effected by arranging alaterally.

tween rows of the terminals in the main body of such control apparatus. Such terminals 13 are connected in electrical'series and are spaced longitudinally to overlap, although they are spaced apart relatively in alateral direction. p

Perforations 14, adapted to register with such rows of terminals, are arranged in lateral alinement jand thus one series of laterally alined perforations will be in continuous contact with the terminals 13 for an interval of time equal to the time required for the tape to pass one longitudinal space between the terminalsin the rows. Theperforations 14 are also adapted to be arranged in longitudinal spacing equal to that of the perforations in the main control and thus continuous operation of the auxiliarydevice alined series of perforations; 14 for each longitudinal space'of the tape. Corresponding intermittent connections may be made by leaving some ofsuch spaces unperforated.

An alternative mode'of effecting such control is by providing a terminal 15 elongated longitudinally of-the terminal pannel a dist-ance equal to or slightly in excess fof the longitudinal spacing of the terminals, and

, a single row of spaced perforations 16. This type of terminal is slightly disadvantageous in that when it is-desired to,flasl1 an aux:

iliary device 17, the minimum length of time ofsuch .flash isthe time necessary for the tape to move one longitudinal space. In the first described modification a flash can be produced in the auxiliary devicesofsuch length only as is necessary for a perforation to pass into and'out of registration with its terminal, which is only one-half or one-third of the longitudinal space, as shown The series-connected terminals 13 are connectcd to the auxiliary device 12 bya wire 18 and such device is connected to the bat .tery 7 by a wire 19. The auxiliary device .17 is connectedtoits-terminal 15 by a wire 20 and to the battery 7 by a ire 21.

For manufacturingpurposes it'may some times be'desirableto make the terminals 15 ofa series of small round, contacts, such as the remaining contacts, and have such c'Ontacts in electrical series witheach other. and

spaced .-apart :a distance different than that of the perforations and preferably spaced lesser, distance. ,By making such terminal 15- in this manner all of the fterminals can V be made .by boring round holeslthru the botpass over such terminals.
