The cam m operates a lever In order to carry my invention into efiect, n, which works a spring-switch 0 of usual I arrange a translucent screen Ct in front of construction for control of the current to the the window or other position upon which the electric-arc lamp 0 of the optical lantern. projected pictures by the optical lantern are The cam m operates directly upon the four- 10c made, and infront of this screen a I arrange way switch 11 in the electric circuit 0 of the a roller-blind b or thelike, upon the front surelectric control mechanism 1*. The control mechanism 7 consists oftwo electromagnets 1' 1- which are connected 'to a battery 1 and to the contacts 12 01 of the four-pole switch H The armatures of the electromagnets r r are mounted on a double-armed lever s, pivoted on the framework and carrying a third arm 8, extending downward. The central portion of this arm 5 engages with the groove of the sliding sleeve j, so that when the arm is rocked about its axisit moves the sleeve either to one side or the other, as the case may be. The lower end of the arm 5 engages with a projection s on a pivoted lever s when it is rocked to the right side and is retained in that position thereby until released. The lever s has an upwardly-extendin arm 8 having an adjustable contactscrew .9", adapted to operate a spring-switch t in the shunt-circuit if from the main circuit 19 to the motor 7L and is used merely for the purpose of starting up the motor h. The arm 5 is released from engagement with the pivoted lever s by means of a lever pivoted on a bracket the end of the lever t engaging the arm 8', so as to depress the same when engaged by a pin t on the wheel Z. The battery r is connected to the contact-finger g of the timing mechanism, and the contacts g g thereof are connected to the contacts 01 of the switch 91 The lantern-slides it are carried around the periphery of a large wheel to, to which an intermittent motion is given by the electrometor by means of a gear consisting of a cam n carried at the end of the axle j. This'cam uis adapted to oscillate the lever u which latter carries a spring-pressed'pawl u, situated so as to engage with pins a situated around the wheel to, the number of the pins being the same as the number of lantern-slides u around the wheel. The lever 1,0 is arranged so that it is moved on its backward stroke by the cam a and on the forward stroke to move the wheel to, which is effected entirely by a spring a attached at one end to the lever u In order to insure a correct register of the lantern-slides in front of the project ing-lens, I pivot a weighted lever v on the framework, the said lever having a semicircular recess 4:, adapted to engage one of the pins a at the end of each intermittent move- 'ter w to act as an occultator.

ment of the wheel 10.

In order to prevent a movable image on the screen a during the change of position of the lantern-slides, I provide an oscillating shut- This shutter w is operated from a cam 10', carried by the shaft j, pivoted lever 10 connecting-rod 20 lever 20 and axle 10 the shutter to being fixedly carried by the latter.

The operation of my device is as follows: It is assumed that the timing mechanism f is wound up and going, the main circuit 29 is connected to a source of electric current, and the machine is in its quiescent condition, such as in the day-time, when the permanent advertisement is exhibited on the blind b.

As soon as the contact-finger g? touches the contact 9 a current passes from the battery 1' to the electromagnet 1*, drawing down its armature and the lever s. This action makes the electrical shunt-circuit t and allows current to pass to the motor to start it, and simultaneously the lever s pushes the sleeve j 'to the right, so as to make the clutchj engage the wheel k. The motor then gradually rolls up the blind and also causes the cam m to operate the lever n and close the main motor-switch 0. When the blind is nearly at the top, the cam m operates the lever 'n and closes the switch 0 of the arc-lamp. At the same time the cam m moves the four-way switch 01 over to the other contacts a 'n, so that the battery 1' will not run down, as the contacts on the timing mechanism are not broken for some five to ten minutes, as the movement is so slow. Just as the blind is wound up the pin t on the wheel I engages the lever 3 depresses it, and allows the arm 3 to be disengaged from the projection 5 and to assume its normal central position, which is effected by the two adjustable springs 3, one being on each side of the arm 3 This action immediately pulls the clutch j out of engagement with the wheel 7c. The motor then continues to operate the wheel tt' by means of the lever 11 and pawl 1.64, the cam to moving the shutter u: so as to obscure the picture during the movement of the lanternslides. When the contact-finger g of the timing mechanism f makes electrical connection with the contacts a 02 the electromag net r is energized, and the lever s puts the clutch j into gear with the wheel j, the blind Z) is unrolled, the arc-lamp switched oft, and the four way switch n is returned to its original position, and finally the current is switched off from the motor, the arm 3' returning to its central normal position ready for the next period of operation.

Although I have described my invention as being operated by an electric motor and illuminated by an electric lamp, it is quite obvious any other motor and illuminating agent can be used by substituting equivalent control devices in substitution of the electric switches 13, 0, and 0. I may make the screen a as a roller-blind, which can unroll when the roller-blind Z7 is being wound up, and vice versa.

Having now described my invention, what I claim, and desire to secure by Letters Pat cut, is

An advertising device consisting of in combination, an optical projecting apparatus, a translucent screen arranged to receive the image projected thereby, a rotating lantern slide carrier, means for giving the said car rier an intermittent motion from continuous motion, a uniform-speeded motor for driving the machine, a timing mechanism having electrical contacts, an electrical control mechanism controlled by the timing mechanism, a roller-blind carrying permanent advertis- IIC) ing matter, a winding mechanism adapted to motor and of the lighting agent to the optical IO lantern, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

ROBERT WILLOUGHBY muse.
