HENRY KINGSFORD HAR-RIS. OF LONDON, ENGLAND.

ADVERTISING DEVICE AND THE LIKE.

Application led December 10, 1912.

To all whom t may concern.'

lle it known that I, HENRY Knvosroin) Hansis, a subject of the King of England, residing at Park llIansions, Knightsbridge, London, England, have invented certain new and useful Improvements in Advertising Devices and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to lwhich it appertains to make and use the same.

This invention relates to devices for making public announcements exhibiting advertisements, and for other purposes of a like nature and refers to improvements upon the type of such devices for Which I have obtained Letters Patent No. 1,138,471, dated May i, 1915.

lWith devices made according to my former invention I provide a frame or frames each frame having a band or bands or other equivalent device bearing letters, numerals or other indications thereon and by electrical means I set each such band or equivalent device in the required position from a distant station so that the letters in all the frames spell out an advertisement or other announcement which it is desired to exhibit.

My present invention relates to means by which an apparatus or device which I term a selector and which is provided in connection With each frame or the like at the exhibiting station is set according to requirements in such a Way that when the band or other equivalent device in the frame is set in motion or released, it is automatically stopped by the selectingV apparatus when it comes into the proper position for exhibiting the required letters, numeral, device or the like.

The selector is in all cases so constructed and arranged With respect to the advertisements or the like which are to be exhibited or with respect to other devices which are to be actuated or brought into position that the selector itself can be set from a distance into a new position Without disturbing the advertisements or other devices which have been set by its aid, these advertisements, devices or the like being brought into the new position determined by the fresh setting at any subsequent time.

In the typical. Way of carrying out my Specification of Letters Patent.

Patented Apr. 25, 1916.,

Serial No. 735,935.

invention as'applied to an advertising device I provide in thc exhibiting station an apparatus which I term the selector Which by means of electrical, pneumatic or purely mechanical means or by a combination of these means may be set in a number of positions,such apparatus heilig provided with devices for stopping the movements of rollers or other devices controlling the positions of the bands, fiaps or the like so that according to the position in which this selector' is set the motions of the bands, fiaps or the like are stopped or controlled so that the letters or numerals or other devices are brought into the desired positions in the eX- hibiting station.

While an apparatus constructed according` to my present invention can be adapted to be operated from a distance by mechanical, pneumatic or other analogous means I prefer to construct the apparatus in such a Way that it is adapted to be set in position by a number of electrical impulses communicated from a sending station. To eifect this I provide the sending station with a llVheatstone telegraph tape or hand operated key or other device which is adapted to send electrical impulses along a line or lines or other equivalent to the exhibiting station. These impulses cause a Wheel or the like to be rotated through a certain distance according to the number of impulses transmitted from the sending station, such Wheel bringing the stop or equivalent device into a suitable position for enabling a band or other exhibiting device in the eX- iibiting station to be stopped in a position corresponding to that in which the stop has been set by the impulses, means being also added when the selector for one frame or the like in the exhibiting station has been set in position for causing the next set of impulses to produce the setting of a seleotor in the next succeeding frame and so on until all the selectors for the various frames are set in position, after which a motor is started which actuates all the bands or the like and brings them into the exhibiting positions determined by the various selectors, the operation of setting the selectors being then recommenced after any desired interval so that a continuous series of advertisements or announcements in the exhibiting station vmay be controlled and drawings which show one way of applying a selecting device constructed according to my present invention to an exhibiting frame provided with a band bearing letters or other devices or announcements.

Figure 1 is a side elevation of one exhibiting frame which I term a unit with the selecting device adapted thereto. Figs. 2 to 11 show details in connection therewith. Fig. 12 shows a diagrammatic perspective view and Fig. 13 shows sectionalelevation of one form of hand setting mechanism. Fig. 14 shows a plan of a detail of same.

f Fig. 15 shows electrical connections of certain parts hereinafter fully explained.

The same letters Vand numerals of referlence are employed to denote the same parts in all the views.

a shows a framework which has mounted therein a spindle b carrying a roller c.

Therek is also mounted therein another spindle el. to which is connected another roller e.

f is a large gear wheel mounted loosely on the spindle b and connected to a spiral spring g at h. The other end of the spiral spring g is connected to the spindle b.

`lf; "is a pin mounted on the side of the roller c and working in a slot m cut in the wheel f.

` nis another gear wheel mounted loosely around the spindle Z and meshing with the gear wheel f.

p and q are guide pulleys. y

, 1' is the band which is wound around the roller c passed over the guide pulleys p and q and then wound around the roller e in such a -way that when the rollers c and e are turned the strip r is unwound from one roller and wound up on the other roller.

s is a ratchet wheel mounted upon a spindle t and connected to a spring barrel u provided with a coiled spring which normallv tends to turn the wheel s in the direction of the arrow 0.

w is a leverpivoted at 2 and formed with a nose 3 which' nose is kept normally pressed against the ratchet wheel s by a spring 4.

5 is another Vlever pivoted to the framework a at 6, and connected to the lever fw bymeans of a pin 7. The lever 5 has pivoted thereon at 8 a locking pawl 9 the'nose l10 of which is out of engagement with the teeth of the ratchet wheel s when the nose 3 of the lever w is in engagement, but while the nose 3 is out of engagement the nose 10 is in engagement, the whole device forming an extremely sensitive escapement.

11 is a link attached to arm w and to the armature 12 of an electro-magnet 13 mounted upon the framework a..

1t will be seen that if the armature 12 of the electro-magnet 13 be attracted the nose 3 is withdrawn from engagement with the teeth and the nose 10 brought into engagement, which movement, however, allows the ratchet wheel 8 to turn in the direction of the arrow v through half a tooth under the influence of the spring in the spring barrel u. When the magnetic circuit is broken the lever w is pulled over by the spring 4 which causes the nose 8 to rengage with the next tooth of the ratchet wheel s and withdraws the nose 10 from engagement therewith thus allowing the ratchet wheel s to move through another half tooth under the action of the spring in the barrel u, the result is that for each electrical impulse passing around themagnet 13 the ratchet wheel s moves under the influence of the spring in the Spring barrel u through a distance of one tooth. The wheel n has mounted thereon a grooved cam 14. This groovcd cam 14 has working therein a roller 15 mounted at the end of a lever 16 pivoted to a slide 17.

It will be seen from Fig. 1 that the lever 16 is located behind the framework a and that in Figs. 2, 3, and 4 the said lever is shown working with regard to the cam 14 with the said plate removed.

The slide 17 carries on the front -a bracket 18 which has pivoted therein a pawl 19 which carries a roller 20 working upon an incline 21. 22 is a lever normally pressing upon the roller 2O by means of a spring 23.

Referring now to Figs. 2, 3, and 4, at Fig. 2 the roller 15 is seen located in the grooved cam 14.4 If now the cam 14 is turned in the direction of the arrow Fig. 3, the roller 15 is caused to rise turning up the lever 16, and imparting no action to the slide 17, whereas at Fig. 4 where the cam is being turned in the opposite direction the roller 15 is being forced outward pushing outward the slide 17. This latter action is caused by the stop 24 (see Fig. 5) which does not permit of the lever 16 to be rocked downward, and, therefore, as the rise on the cam approaches, the slide 17 is forced outward. Referring now t0 Fig. 1 as this slide 17 is forced outward it takes with it' the pawl 19 which as it advances is pressed downward by the lever 22 so that its nose 25 comes into engagement with a tooth of the ratchet wheel s and as the pawl is advanced the ratchet wheel is turned in the reverse direction to the arrow e through a distance of one tooth, the locking being efe fected by means of the escapement previously described.

Mounted at the side of the framework a and coming just above the slide 17 is a pivot 26 which has mounted thereon a lever 27 formed with a forked opening 28, the lever 27 working between the stops 29 and 30 and kept pressed against the stop 29 by means of a spring 3l connected at one end to the frame a and at the other end to an arm 32 in connection with the spindle 26.

33 is a roller mounted on an arm 34 attached to the ratchet; wheel s and projecting slightly therefrom. The roller is so mounted that when the ratchet wheel s is rotated in the reverse direction to the arrow v the said roller 33 comes in 'contact with the fork end 28 of the lever 27 and forces the said lever 27 into contact with the stop 30. No further movement of the roller 33 in this direction can take place. This action is for the purpose of setting the blinds in the initial position in a manner hereinafter described.

The spindle 26 passes through the framework a and carries on the inside a lever 35 see Figs. 8 to 1l. The wheel a has out in the sides thereof notches 36, at one side of which are arranged projecting blocks 37 and at the other side of which are pivoted spring controlled pawls 38. The lever 35 has mounted thereon in the manner hereinafter described a projecting block 39 which when the lever 35 is in the position shown at Fig. 8, that is, when the lever 27 rests against the stop 29, does not come into `the path of the pawls 38; but when in the position shown at Fig. 9, that is, when the lever 27 is pressed against the stop 30 by the roller 33, this block projects into the path of the pawls 38, and if the wheel n is being turned the said pawls spring past the said block, allowing the block 39 to enter the cut away portion 36 which stops the rotation lof the wheel n as the projecting portion 37 cannot pass the block 39. In order to prevent any sudden jar this locking may cause, the block 39 is preferably mounted and made in the manner shown at Figs. 10 and 1l. Here it will be seen that the block 39 is connected to a slide 40 which slides upon slideways 4l and is kept in the normal position by compression springs 42. The block 39'may also if desired be made of some cushioning compressible material such for instance as raw hide or hard rubber.

The roller e is not directly connected to the shaft Z but is provided with the mechanism shown in side elevation at Fig. 6 the said elevation being taken from the opposite end of the roller to that shown at Fig. l. In this ligure 43 is a ring located in a hollow at the end of the roller and firmly attached thereto. This ring 43 has a number o-f notches 44 cut therein.

45 is a collar `pinned to the shaft d. This collar carries two arms 46 and a guide 47. Working on the guide 47 is a double inclined piece 48. u

49 are pins passing through the arms 46 and attached to thelower portion of the double inclined piece 48. Between the arms 46 and this lower portion of the piece 48 compression springs 50 are located.

52 is a roller shown on the drawing resting in a groove 51 out in the piece 48 and also in engagement with one of the notches 44. In this position if the shaft Z is driven in either direction it carries with it the roller e owing to the connection provided by the roller 52. On the other hand should any great braking strain be put upon the roller e, such for example as that previously described in connection with the block 39 this would cause the roller 52 to press down the piece 48 and to roll down one of the inclines into such a position that it no longer connects the driving part to the roller c. It will be seen, therefore, that although the roller e has stopped the driving shaft Z is still turning but having no effect upon the roller e. Should the direction of rotation of the shaft (l be reversed then the roller 52 would ride up one of the inclines and assume the position shown at Fig. 6, until it is again thrown out by braking action.

It is particularly to be observed that the disengagement takes place in whichever direction the driving' shaftd is being driven, as soon as a certain braking strain is eX- ceeded and that on reversing, the parts are engaged.

Another method of carrying this into effect is shown at Fig. 7. In this case the shaft Z has ixedly mounted thereon a toothed wheel 53. 54 is a spring barrel mounted upon a plate 55 working loosely around the shaft CZ but Xedly connected to the roller c. 56 isa pawl mounted at 57 upon a slide 58 working in the spring barrel 54. It will be seen at Fig. 7 that if the wheel 53 is rotated in a clockwise direction it will carry with it the roller e but if the roller e is stopped, then thewheel 53 will carry around with it thepawl 56, compressing the spring 59 until the pawl is carried to the other side of the wheel, in which position it merely slips over the teeth. Thus it will be seen that a similar effect is produced to that explained with reference to Fig. 6.

In establishing an exhibiting station according to the present invention, I provide a number of frames or units each fur` nished with a band or bands and selecting device with associated parts such as those already described, I also furnish a device which may somewhat resemble a commutator, and which will be described hereinafter forY enabling a set of impulses to be given to the first unit in order to set the selector in that unit, after which the connection to this first unit is broken and the second unit is thrown into connection with the sending station so that vthe selector in the second unit is set from the sending station, kafter which the third unit is brought into connection and so onthroughout the whole series of units. Each of the units is provided with a clutching and unclutching device such as that already described with refl i coupled shafts erence to Fig. 6 and a common shaft or d are provided for operating theilower roller from a` suitable reversible motor.

I will `n ow describe the method of setting the various units from the distant station. Ve will suppose all the bands have been placed in position `and that it is proposed to set all the selectors in the exhibiting station ready for bringing the next advertisement into posit-ion. It should be noticed that, owing to the fact that the rollers o and e are of specially large size for allowing a length ofy band equal to two letters to be wound around them, I provide two pawls 3S upon the lower wheel a, and when one of these pawls is engaged by the block 39 a complete letter is being shown atethe front of the frame. It is also to be noticed that any slight variation kin diameter of the rollers owing to the different amount of band rolled on the-circumference ofthe same is compensated for by the mechanism described in connect-ion with*` the spring g and the groove m.

It is to be remembered that all the rollers 33 are engaged in the'corresponding forks 28. For setting the lirst selector a number of electrical impulsesl are transmitted from the sending station by one of the devices hereinafter' to be described. Each of these impulses causes the wheel s to unwind through a distance of one tooth under the influence of the spring in-the barrel u as previously explained. This movement of the wheel s lcauses the roller 33 to be disengaged from the fork 28 and to be brought around through a distance corresponding to the number of impulses transmitted. The removal of the roller 33l from the fork 28 enables the spring 31 to rock over the arm 35 thus removingthe block 39 from engagement with the pawl 38 and block 37. After the first lselector has been set inthis way, it is disconnected from the sending stationby the commutator device before alluded to and the second unit and selector are brought into the circuit, and a fresh series of impulses are transmittedfrom the sending station by which the second selector is setin a manner precisely similar to that described with respect to the iirst selector, the process being centnued until the last selector has been brought into position. During the whole of this period, that is while the selectors are being set, it will be remembered that the advertisement previously set is being exhibited and this exhibiting may continue for any required time until the selectors are in a position ready for producing the next advertisement. Then it is required to show this fresh advertisement it is simply necessary to proceed as followsz-The motor is started which communicates motion to the shaft Z in the direction of the arrow Fig. 3. This causes the bands to be all brought back to the zero position, each of the clutching devices illustrated with reference to Fig. G becoming disengaged as soon as the band of a particular unit reaches the end of its course and consequently the tension on such band overpowers the springs 50 of the particular clutch. Then all the bands are set back to their initial position the motor is reversed and each of the clutching devices illustrated at Fig. 6 lirst of all comes back into the position of engagement although the drive is now in the reverse direction. As the motor continues, all the rollers e are turned in the direction of the arrow Fig. 4, and the cam 14 causes the pawl 19 to wind up the wheel s through a distance of one tooth twice in every revolution. This action continues until the roller 33 engages in the fork 28 which causes the block 39 to be brought into the path of the next advancing pawl 38 (see Fig. 9) with which it is engaged thus stopping the roller and causing the tension put upon the blind to throw out the clutch, Fig. 6. This setting proceeds throughout all the units, and although the shaft l is being driven during the whole of the time when all the selectors are being set back, this does not occasion any difficulties owing to the fact that as soon as any one of the selectors has been set back to the initial position, the block 39 of the particular unit causes the drive of the roller e to be stopped.

I will now proceed to describe typical forms of devices which I propose to use at the sending station for sending out the electrical impulses to the exhibiting station, although I may use any form of impulse transmitter. The first of these devices is a hand operated device and is illustrated more particularly at Figs. 12 and 13. In these figures 592 is a casing which has mounted thereon a disk of insulating material 60. This disk has let in the surface thereof three metallic rings 61, 62, and 63.

64 are a number of metallic contacts insulated from each other on the top of the disk G0, but connected in series at the bottom of the said disk.

65 is a tubular shaft mounted in bearings 66, having connected thereto an arm 67 and an indicating disk 68. The disk 68 comes under and forms the surfaceof thel casing Medela and is provided with an indicating mark or pointer 69.

is a ring-like dial carrying suitable indications corresponding to the indications carried by the bands or blinds. The arm 67 carries `a number of spring contacts 71, 72, 73, 74 the contact 71 being located above the contacts 64 and contacts 72, 73 and 74 above the rings 63, 62 and 61, respectively. It should here be remarked that the contacts 71 and 74 are connected electrically together and the contacts 72 and 73 are connected electrically together .and insulated from the other contacts. The sleeve 65 has passing loosely therethrough a rod 75 provided at the bottom with a contact making disk 76 upon which normally presses a conducting spring arm 77 to which one end of the conducting wire is connected. The spindle 75 is connected to the forked part of a handle 78, pivoted at 79 to a cap 8O which lits over the end of the sleeve 65, and is kept in position thereon by means of a pin 8l. The cap 80 is free to turn upon the sleeve 65 but cannot be removed therefrom.

82 is a rod projecting from the underside of the handle 78 and passing through the extension 83 on the cap 80.

84 is a corresponding spring located between the projection 83 and the underside of the handle 78. This compression spring normally keeps the end of the pin 82 upward, but when the handle 78 is depressed the pin 82 can enter a hole 85 in the disk 68. As the disk 68 and the arm 67 are fXedly connected to the sleeve 65, when the pin of the handle 78 is inserted into the hole 85 and the handle is turned so that the pointer 69 points to the desired indication upon the dial 70 it follows that the contact 71 is making contact with the particular contact 64 corresponding to the indication shown by the pointer 69. No current, however, passes through this contact, as upon pressing down the handle 78 the conducting piece 76 is removed from the spring contact 77 and it is not until the handle 78 is allowed to spring upward under the action of the spring 84 that a current passes between this contact, as it is only then that the conducting plate 76 comes into contact with the conducting spring 77. 86 is a bevel wheel attached to the sleeve 65; this gears with another bevel wheel 87 mounted upon a shaft 88. The shaft 88 passes through suitable bearings and is connected to a ratchet 89 in connection with a spring barrel 90.

91 is a gear wheel in connection with the ratchet wheel 89 (the said wheel 89 having an equal number of teeth to the contacts 64) by means of a suitable pawl in such a way that when the clockwork is being wound up the wheel 91 is not turned but when unwind ing the wheel 91 is turned. The wheel 91 is in connection with a suitable vane governor ceeds to the magnet 130, which,

92 by a suitable train of wheels, so that the speed with which the shaft 88 is allowed to turn is practically uniform.

It should here be remarked that when the apparatus is put together a certain tension is given to the spring within the spring barrel 90 and that the direction in which the spring tends to turn the disk 68 is that of the arrow 93. The disk 68, however, is prevented from entirely turning by means of a suitable stop which normally brings the aperture and the pointer 69 to indicate zero or initial position. W'hen, however, the handle 78 is depressed and turned in the opposite direction to that of the arrow 93 so as to bring the pointer 69 opposite the required indication, then as the connecting pin 82 has also turned the disk 68 and the arm 67 through a similar angle, when the handle 78 is allowed to spring upward the arm 67 is caused by the spring in the spring barrel to turn back to its original position, but in turning back the contact 71 passes over a certain number of contacts 64 and each time a contact is reached a separate electrical impulse is transmitted to the eX- hibiting station. The speed with which the contacts are made is governed by the turning of the vane 92 but it must be such that the escapement in the exhibiting station previously referred to has ample time to operate.

Referring now to Fig. 15 in this view a diagram of connections is shown with reference to a hand setting device similar to that shown at Figs. 12 and 13. In this figure, only fourteen contacts 64 are shown for the sake of simplicity. A ring 63 is also partly broken away and a separate contact 93 is provided with which the contact 72 can engage. 94 is also another contact adapted to electrically connect with the contact 71.

It will be seen that the inner ring 61 is connected to the positive side of the battery or other source of power 95 and that the other or negative side is in connection with the ring 62. The contacts forming the series 64 are connected to the line through a suitable indicator 96 of such a character that the particular letter set is shown in the window. This may be a magnetic or other suitable indicator. The line passes to the arm 98 of the commutator for switching the units successively into circuit. The outer ring 63 is in connection with the earth for the return. Connected to the contact 93 is another line passing through the indicator 100. This moves every time the contacts 71, 72 carried by the arm 67 come into contact with the contacts 94 and 93. The line then proeach time it is energized causes the arm 98 to be moved from one contact to the next in order to bring a new unit into the circuit.

Referring to the upper part of the Fig. 15

exhibiting units 104 are shown diagram- `'matically, connected by-suitable lines with the-studs or contacts on the commutator on the one hand and on the other hand to a suitableV liney in yconnection with-the earth return. 41t will'be understood that each of these units has its own operatingmagnet. 101 and 102 are two extra contacts on the commutator, overy which the arm 93 passes on its yreturnffrom the last contact to the first in connection with the exhibiting units.

103 isa motor starter adapted to bring the exhibiting band or the like back vto zero or the non-exhibiting position when moved in one direction and adapted to set bands into fresh positions determined by the selectors when moving in the opposite direction. 103 is a localsource of power connected to the motor circuit.

The generaloperation of the device will v now be described.

It will be seen that the arm 67 carrying the contacts, hasb'een set in a clockwise direction to the eleventh contact starting from behind ythe Contact 94. As itl comes back under the action of its spring inthe direction 'of the arrow 11 separate electrical impulses are sent to the unit with which the transmitter is then in connection, the path ofthe current being as follows: Starting from the positive side of the source of power the current passes through the inner ring 61, from the inner Vring lacross the arm 67, Figs. 12 and 13-,\to the contact 71 at the end of the arm, thence to the particular Contact 64, lthrough the series connection of the contacts' 64 to the line through the indicator 96 thence along the line to the arm 98, thence to the particular letter unit'and to the magnet operating the selector in that unit, thence to the earth return, to the earth connection ofthe transmitting station, to the outer ring 63, across the bridge piece between the contacts 72 and 73, to the ring 62 and thence tothe negative side of the battery- The selector in the particular unit being set, it

' is necessary to 'bring the next unit into the circuit. This is effected in the following manner z-As the arm 67 returns to the zero position it vcornes over the contacts 93 and 94.` This-closes the circuit to the magnet 130, the' path of the current being as follows: Starting from the contact 93 through the line and the indicator 100, to the magnet 130, to earth, fromearth back to the contact 94, from which point the circuit is completed by the contacts in connection with the arm 67 as before described.

Withregard to the transmitting station lit/willl also be understood that the methods of sending electrical impulses previously de- 'scribed are given merely by way of example yas any suitable devices for'transmitting such impulses Vmay be employed. For instance, Jacquard cards, resembling those described in connection with my patent before mentioned may be ,adapted for operating the selectors and commutators or any of the means employed in telegraphy or telephony.

In general, I wish itl to be understood that any kind of selector may be used which carries out the objects of the invention, and that the selector may be operated by any suitable source of power and in any required manner. 1Where an escapement is employed it may be of any type, and where it is electrically, controlled, it may in some cases be actuated by alternate positive and negative currents.
