JIMENEZ AND JULIO C. JIMENEZ, F HABANA, CUBA PATTERN-SHEET CONTBOLLED SWITCH FOR ILLUMINABLE SIGNS Application filed June 28, 1930, Serial No. 484,639, and in Cuba. September 3, 1929. I

This invention relates to a pattern-sheet controlled switch'designed primarily for use in connectlon with luminous continuous signs, but it is to be understood that a circuit.

controller in accordance with this invention ling an illuminable display, from a signboard or other object.

A further object of the invention is to provide, in a manner as hereinafter set forth a controlling device for the purpose referred to capable of performing its function when the signboard or other object upon which the display is to be had is located at a point remote from theswitch.

Further objects of the invention are to pro vide, in manner as hereinafter set forth a'circuit controller for the purpose referred to which is comparatively simple in its construction and arrangement, strong, durable, compact, thoroughly efficient in its use, readily assembled and comparatively inexpensive to manufacture.

In the drawings Fig. 1 is a front elevation of the switch. Fig. 2 is a fragmentary view in rear elevation.

i Fig. 3 is a detailed section illustrating a set of spring controlled circuit closing elements and further showing the circuit controlling element of the pattern sheet type in the form of a perforated ribbon and which is common to the several lighting circuits.

Fig. 4 shows one of the rollers of the spool, serving to move the circuit controlling element.

Fig. 5 is a detail of the inside rollers serving to guide the circuit controlling element when in motion.

Fig. 6 shows a section taken along line A-B Fig. 5.

Fig. 7 shows the circuit controlling element in the form of a ribbon or film in which, as an example, the pattern in the form of letters A. J. provided by perforations. 1

By referring to the drawings it may be seen that A .is a spool or drum formed by two circular

annular rings

1 and 2 joined and maintained in fixed spaced relation by bolts 3 and spacers 4 arranged between and secured to lugs 5 extending inwardly from the inner {edge of

rings

1 and 2. Between said rings and near the inner edges thereof are rollers 6, carried and rotated by shafts 6 which pro ject from the ends of the rollers. For the purpose of making all said rollers 6 drivers, each shaft 6 is provided with a pulley 7 rigs idly mounted near one of the ends of the roller. The normal position of the spool A is vertical and it is sustained by means of

supports

8 and 9, secured to base 10.

The circuit controlling or switching mechanism B is lodged interiorly of spool A, to which it is secured by means of a framing G, suitably held by a gusset 11 fixed to a horizontal member 12, having its ends attached to a pair of lugs 5 of ring 1. The mechanism springs 19 lodged interiorly of said metallic tubes 16. The said springs having one of their ends resting on the lower part of screws '18 and the other resting on metallic balls 20.

The said balls are adapted to contact the outer as face of rim 21 of a metallic wheel 22.

The wheel 22 is rotatably mounted in the framing C and electrically insulated therefrom by means of a fiber or other suitable means.

The rim 21 of the wheel 22 (Fig. 3) is provided with teeth 23 at one of its sides, said teeth being separated from the rest of the rim by means of an annular groove 24 serving to prevent the circuit controlling element of the pattern-sheet type and in the form of a ribbon or film 25 to be struck by the tooth or sprocket wheel 26, which imparts movement to wheel 22 by means of engaging the teeth 23 of the latter. ,The sprocket wheel 26 is rotatably mounted in framing O and is driven from a worm 27 operated by a reduction gear driven from motor 28 The reduction gearing consists of the

sprockets

29 and 29. The wheel 28 is operated at the desired speed, the reduction gearing providing therefor.

In order to synchronize the movement of the different parts that intervene in the movement of the film or ribbon 25, a pulley 30 is mounted by wheel 26 for the purpose of transmitting'motion by means of a chain or belt 31 to a pulley 32 serving to move, simultaneously the rollers 6 by means of belt 33 travelling. on the pulleys 7.

To maintain the ribbon or film in a correct position during its travel we provide: at

the lower part of rim 21 a pair of rollers 34 capable of oscillating in framing C upon a shaft 37, which is provided with a slot 38, serving to allow passage therethrough of the ribbon or film 25 (Figs. 5 and 6), as to be ex plained hereinafter, and at the upper part 39 of rim 21, rotatably mounted supports 40 are provided capable of oscillating on framing C. The said

supports

36 and 40 being held in working position bymeans ofopposed, oppositely acting springs 41 and 42 which are suitably secured thereto and also to fiXed holders on the wheel 22. In addition to the aforesaid rollers an oscillating plate 44 is fixed to a shaft 45, firmly secured to framing C and serving to uphold the ribbon or film 25 upon issuing from holder 14.v To prevent possible twisting of the ribbon or film 25 after passing over plate 44, a guide 46 is provided on the interior periphery of ring 1 and which is in the shape of a fork.

As the ribbon or film 25 tends to sag at the lower end of spool A, such sag ultimately interfering with the proper working of the device, we provide a fixed brake 47, secured at one of its ends to shaft 48 and having its other end sustained by a pin 49 and which allows regulation of its pressure according to the length of the ribbon wound on the spool.

It is understood that as the holder 14 is of dielectric material andv each of the spiral springs 19, tubes 16 and covers 17 constitute a pole, whereas since wheel 22 is metallic and is electrically connected to battery 50 by means of brush 51 provided in framingC, it constitutes the other pole that is to say, when a ball 20 passesthrough an opening in ribbon 25 to contact with rim 21 whereby the corresponding lamp is illuminated.

Operation (A). Take one end of ribbon or film 25 with the advertisement perforated thereon and pass same from the outside to the inside between two rollers 6 of those occupying the second quadrant.

(B). Pull film gently and pass through slot 38 provided in shaft 37 1 Pass same between rollers 34 and 3;?

(taking care that 35 mounts on the ribbon). (D). Introduce its end in the space limited by holder 14 and rim 21, and rotating wheel 22, slowly advance ribbon until its end issues through the outer end of holder 14.

Pass ribbon over plate 44 and then lodge same between forkedshaped guide 46 secured to ring-1.

'(F). Roll balance of ribbon on spool A until end isreached, at which time both ends thereof are permanently attached to each other, taking care to allow suflicient sag.

(G). Start motor 28 which, through worm 27 and

gears

29', 29 and 26 imparts motion to wheel 22 which will impart motion to rib bon 25, forcing same .to move. Once the rib bon is in motion, every time a perforation 52 coincides with a ball 20, the corresponding circuit will be closed, lighting lamp 53 of the board or signboard, the plurality of lighted lamps producing the word or words constisame time giving the sensation of motion. The foregoing operation is repeated aslong as the device in motion as the perforated ribbon is endless.
