ADVERTISING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 556,136, dated March 10, 1896.

Application filed May 9, 1896. Serial No. 5%,669. (No model.)

To all whom it may concern:

. Be it known that I, TIMOTHY G. DALY, a citizen of the United States, residing at Boston, in the county of Suifolk and State of Massachusetts, have invented certain new and useful Improvements in Advertising Apparatus, of which the followingis a specification.

This invention relates to an improvement in electrically-operated advertising devices; and it consists in the novel features of construction and relative arrangement of parts hereinafter fully described in the specification, clearly illustrated in the drawings, and particularly pointed out in theclaims.

Reference is to be had to the accompanying five sheets of drawings, forming a part of this application, in which like characters are used to indicate like parts wherever they occur.

Figure 1 represents a front elevation of my invention shown as mounted in a suitable casing. Fig. 2 represents a rear elevation of my device, the casing being broken away in order to show the construction of the several parts. Fig. 3 represents a vertical section on the line 3 3 of Fig. 2, looking in the direction of the arrow. Fig. at represents a vertical section 011 the line 4 4 of Fig. 2, looking in the direction of the arrow. Fig. 5 represents a cross-section on the line 5 5 of Fig. 3, looking in the direction of the arrow. Figs. 6 and 7 represent, respectively, front elevation and vertical sections of the apparatus for making and breaking contact.

a represents a receptacle or casing suitably ornamented and of any desired configuration, provided with an aperture a through which the advertisement carried upon an endless belt I) can be seen. This belt is preferably divided into a series of spaces 79, one for each particular individual advertisement.

a represents a dial provided with spaces or divisions a in which may be arranged indexes of the different classes of business advertised upon the belt I). This may be done by printing the words, such as Hardware, &c., or preferably by placing in these spaces the letters, as shown, the letter A, for instance, standing for any class of advertisements beginning with this letter. In the center of said dial is arranged an arm a with a pointer a arranged to register at any desired space (0 In order to maintain this pointer at any desired space it is provided on its under side with a pin a, that engages in one of a series of depressions a on the face of the dial. The arm a may be rigid and this pin a spring-pressed, or the pin may be rigid with the arm and the arm be made of spring metal. Preferably, however, the pin is mounted in a depression (not shown) on the under side of the arm or pointer and pressed outwardly by a spring. (Not shown.)

The dial and pointer just described c011- stitute an indicator. The arm a" is affixed to a short shaft a extending through the front of the casing and having upon its other end a beveled gear a which meshes with a similar gear 0, upon a shaft a, (suitably journaled upon a framework40 that supports the several parts of the apparatus and is arranged within the casing (0,) having a gear 0. upon its opposite end which meshes with a gear a upon one end of a downwardlyextending shaft 0., that is suitably j ournaled upon said framework. The shaft o has on its lower end a gear 0. which meshes with a gear a upon a horizontal shaft a journaled in suitable standards a secured to the framework.

The belt I) or series of belts maybe of cloth or any suitable material, and is supported by rolls b journaled in suitable bearings secured to the upper and lower part of the framework. Said rolls are arranged to be rotated by means of a suitable motor 12 upon the shaft N, on which there is an endless screw b which meshes with a spur-gear b rigid upon a shaft 19 upon which one of the rolls b is mounted.

For the proper and accurate display of the advertisements it is necessary to cut off the power or break the circuit at the right number of revolutions of the rolls and also at the right point in said revolutions. I accomplish this by connecting to the main source of power or the main circuit an auxiliary circuit, both in circuit with the motor. I have arranged the circuit-breaking attachments in the main circuit to break the main circuit at the right number of revolutions of the rolls, and a circuit-breaking attachment in the auxiliary circuit arranged to break the auxiliary circuit and thus stop the machine at the right point in the last of said revolutions. To this end it is necessary to have the auxiliary circuit broken at each revolution, so that any desired number of revolutions may be selected by means of the circuit-breaking attachments in the main circuit. After the main circuit is broken the next breaking of the auxiliary circuit serves to stop the machine, since it is only when both circuits are broken that the current is shut off from the motor.

The means for breaking the auxiliary cireuit comprise, among other things, a disk 11, a lever Z), and brushes a. A disk b is mounted upon the shaft o and is provided with a depression 1) arranged to be in the position shown in Fig. 4t while the advertisement appears in front of the opening of the casing.

Z)" represents a lever pivoted at one end in any suitable part of the framework l0, provided with a lug b arranged to ride upon the said disk and drop into said depression when an advertisement appears in the space. This lever is .pulled down by a spring a when the lug b engages the notch in the disk and is arranged to be raised by the disk and its free end brought into contact with the brushes a" connected to any suitable part of the electrical circuit. The levers b disk 1) and brushes b constitute a make-and-break device for the supplemental circuit, and act to break the supplemental circuit at the right point of each or any revolution, another device hereinafter described serving to break the main circuit at the right number of revolutions. One of the shafts (1 on which one of the upper rolls is mounted (see Fig. l) is arranged at its ends in sliding blocks (1. These blocks are mounted in suitable vertical ways a and are connected to screws a mounted in lugs a integral with the framework. By means of these screws and the associated parts this shaft and this roll can be adjusted up and down in order to put any desired tension upon the belt I) in order to prevent the latter from slipping. The belt will continue to rotate as long as the current is connected to the motor, and during this time the lug Z) on the lever I) will ride on the disk and the free end of said lever held in contact with the brushes (0, except when the lug 1; drops into the depression 0 thus bringing the end of the lever away from the brushes and breaking the circuit. The lever I) will,when the depression in the disk comes opposite the lug b, be pulled downward by the spring, thus breaking the auxiliary circuit.

As the advertisements are spaced in accordance with the periphery of the roll on the shaft that carries the disk, it follows that by breaking the main circuit at the right number of revolutions of the roll that carries the disk and afterward breaking the auxiliary circuit at the right point in the last of said revolutions by means controlled by said roll itself any desired advertisement will be properly placed before the opening. The means for breaking the main circuit are controlled and arranged as follows: Upon the shaft 1) that carries the disk Z) and at the opposite end thereof is secured a pinion (I, that meshes with a spur-gear (1 fast upon a shaft (Z snitably mounted in standards (1 in the framework of the machine. This shaft carries a pinion d, that meshes with a spur-gear d loose upon the shaft a". The gear (1, shaft a", and standards a are made of conducting material. A hollow pin d of conduetin g material is secured in this gear and projects toward the inside of the casing. -Within the cavity (Z of this pin there is mounted a metal block (i pressed outwardly by a spring d", arranged between the end of said block and the end of the cavity in the pin. This block is designed to make contact with a disk (6 rigidly mounted upon a hub (1 made fast to the shaft a" by a screw (W, as shown. The disk (Z is made of conducting material and is provided with an aperture closed by a plug (Z of non-eonductin g material. This plug is arranged to be in the path of movement of the block (Z The free end of leaf-spring d engages the disk (Z near its periphery, the opposite end of said spring being rigidly secured to an insulating-block (l' secured to the framework adjacent to one of the standards a f represents a suitable source of electrical supply, as a battery, one wire, f, of which connects with the switch f The other wire, f connects with the magnet f, suitably mounted upon a standard f connected to the framework. 7 ire f leaving the magnet, passes to the block (Wand is secured to a binding-screwj that passes through the spring (1. By this means the circuit is made from the battery to the disk (1 The wire 1" after leaving the switch f is carried down to the bottom of the casing to a binding-block f having springs upon opposite sides thereof. This binding-post is secured to the base of standard f which is secured to the framework. In the top of this standard f S is journaled one end of the shaft Zr, upon which the motor and endless screw are mounted, the other end of said shaft being journaled in an arm 11 secured to the framework of the machine. Near the standard f on this shaft are mounted two disks f" and f The disk f is fast upon the shaft and the disk f movable. \Viresf connect these disks and are provided midway their ends with balls f. As the shaft rotates, these balls are thrown outward by centrifugal force and tend to draw the disk f toward the disk f in proportion to the speed of the shaft.

Sprinf f are secured at opposite sides of the block (Z and are made of conducting material. The free end of the spring/' is arranged to be engaged by the disk f and to be forced into engagement with the free end of the spring f. The circuit from the battery by means of the wire f is connected at one side to this block (Z and to the spring f From the spring f the current is led by the wire to the motor, thence to the framework 40, thence to the disk (1 and thence to the binding-post f.

The framework 40 is made of conducting material, and a wire f connects a bindingpost f on the framework 40 with the motor. A wire f is connected at one end to the spring (Z by binding-post f and its other end to the binding-post f 31 to which the brushes a are attached and serves to conduct the current to said brushes.

From the foregoing it will be apparent that when the ends of the springs f f are in contact the circuit will be closed at this particular point, which, in the present arrangement, will occur when the machine is at rest, and at all times except when the speed is so high as to force the disk f toward the disk f and to permit the end of the spring f to leave the end of the spring f at which time the circuit will be broken and the motor stopped automatically. The wires f and their attached balls and associated parts constitute a regulator or governor whereby the current is automatically shut off in the event of an excess of speed. There are in effect three switches or points where the main circuit may be closed or broken-to wit, f the springs 7 f and the disk (1 the block (Z"'and the auxiliary circuit is broken at the brushes a.

f is akeeper or armature for the magnetf. This is pivoted at its lower end to a suitable bracket f secured to the framework, and its free end is arranged to engage a lug f fast upon a lever f pivoted between its ends to a standard f secured to the framework. The free end of armature f is kept in engagement with the lug f on the lever f by means of a spring f 21 mounted upon an adjusting-screw f that passes through the armature f This spring is arranged on its adj Listing-screw between the armature and the standard f against which the free end of the screw rests. This screw is ameans for adjusting the path of movement of the armature, and also is a support for the spring. The lever f at one end is connected by a spring f 23 with the lower part of the framework. This end of the lever is connected with a bell-hammer f, positioned to strike a bell f 25 secured to the framework whenever this end of the lever is depressed by the spring. A sliding weight f mounted upon the arm of the lever f serves to adjust the movement of said lever.

A strap f is connected to the opposite end of the lever f from that to which the bellhammer is secured, and passed around a drum f upon the shaft 17 and connected at its opposite end to a lug f upon the framework of the motor. WVhen the strap end of the lever f is raised the strap will be made to hug the drum f and act as a brake to stop the motor. The strap is released from the drum by a reverse movement of the lever. These operations are performed by the movement of the spring f and the armature f \Vhen the circuit is closed to start the motor, as hereinafter described, the magnet f is vitalized and attracts its armature and forces its free end into engagement with the lug f 18 011 the lever f thereby raising the bellhammer end of said lever and lowering the strap end, thus releasing the drum from the strap and the action of the brake. When, however, the current is broken to stop the motor, the spring f will force the bell-hammer end of the lever f downward, forcing the free end of the armature toward the standard f and raising the brake end of the lever f and making the strap engage the drum to act as a brake and stop the movement of the several parts. It will be noticed that this strap acts in unison with the lug Z9 on the lever b that engages the depression in the disk on the shaft d It will be further observed that this brake device is automatically thrownout of engagement when the circuit is closed and automatically thrown into engagement when the circuit at the brushes a is broken. The current of the main circuit from the magnet f is conducted by the continuation of the wire f to binding-screw f spring 61 disk f block d", pin (1 gear (1, shaft a, standard CL23, and thence by framework 40, wire f to the motor. From the motor current is led by wires f to the springs f and f, thence bywire f to battery f. The current for the auxiliary circuit is conducted from the post f 61 by the wire f to the brushes a thence by the lever Z) to the framework 40, and thence to the motor.

From the foregoing it will be seen that while the block cl and the disk d are in contact, supposing the switch f to be closed, the circuit will be closed and the belts driven. When, however, the block d engages the plug (1 the circuit will be broken at this point, but the machine will continue to run until the auxiliary circuit is broken at the brushes a whereby the current is cut off from the motor entirely and the mechanism stopped.

The operation of my machine is as follows: The switch f being closed, and it being desired to show at the opening the advertisement relating, say, to Laundry, the pointerarm is turned until the register stops at the letter L. This movement of the pointerarm is transmitted by means of the shafts a (6116614 a and their respective gears, and there occurs a corresponding movement to the disk 61 carrying the block 61 out of engagement with the plug 01 and closing the circuit, thereby starting the motor. The movement of the motor-shaft is communicated to the shaft b by the screw and thence to the belt, and at the same time by means of the gears 61 d to the gear (1. This movement of the parts will continue until the plug 01 engages the block 61 when the main circuit will be broken, as hereinbefore described, the machine and motor continuing to be run by the current furnished through the auxiliary circuit until said circuit is broken at the brushes a.

It is to be understood, of course that the switch f is only an auxiliary attachment for use when the machine is set aside for an indefinite length of time and to prevent accidental movements of the mechanism when the machine is being exhibited or overhauled. This switch forms no part of my invention, since when the circuit is closed the switch is or may be disregarded. The wire f entering and leaving the switch is one wire. hen the gear (1 and its block is moved by means of the pointer-arm and the circuit closed, the armature f is operated to release the motorshaft from the action of the band-brake f. The plug (Z in its rotation re-engages block (Z thereby breaking the main circuit and forcing the current through the auxiliary circuit until the latter is broken by the lever Z2 dropping away from the brushes a whereupon the magnet f releases its hold upon its armature, permitting the band-brake to be again put into operation.

The framework may be provided with suitable panels 41, and the opening may be protected by glass 4:2, if desired. Preferably a ratchet h (shown in dotted lines in Fig. 2 and in edge view in Fig. 5) is mounted upon the shaft a A spring-pressed pawl 7t is arranged to engage the teeth of this ratchet. By this construction a reverse movement of the arm and of the disk (Z is prevented, it being necessary at all times to move the arm in the direction of the arrows, Fig. 1.

I do not desire to be understood as limiting myself to the precise construction and ar rangement of the parts shown, as many modifications will suggest themselves to those skilled in the art. The circuit-breaking attachment mounted upon the shaft a can be variously modified without departing from the spirit and scope of my invention, which includes two movable parts, one controlled by the indicator and the other controlled by the belt mechanism.

The belt preferably passes over guide-rolls 43 arranged near the top and bottom of the opening a, in order to insure the belts being positioned evenly before the opening.

Having thus explained the nature of my invention and described a way of constructing and using the same, though without attempting to set forth all the forms in which it may be made or all the modes of its use, what I claim, and desire to secure by Letters Patent, is

1.
