EDWIN M. FITZGERALD, OF N EW YORK, N. Y.

ADVERTISING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 251,855, dated January 3, 1882.

Application filed May 27, 1881. (No model.)

To all whom it may concern Be it known that I, EDWIN FITZGERALD, of the city, county, and State of New York, have invented a new and Improved Advertising Apparatus, ofwhich the following is a specification.

Figure 1, Sheet 1, isa front elevation of my improvement, partly in section. Fig. 2, Sheet 1, is a sectional plan View of the same, taken through the line 2 z, Fig. 1. Fig. 3, Sheet 2, is a" sectional side elevation of the same, taken through the line as at, Fig. 1. Fig. 4, Sheet 2,

is a sectional side elevation of the same, taken through the line y y, Fig. 1. Fig. 5, Sheet 2,

is a sectional elevation of a part of the operating mechanism.

Similar letters of reference indicate corresponding parts.

The object of this invention is to secure the automatic changing of a series of advertisements at regular intervals.

The invention consists in an advertising apparatus formed by combining with a clockwork a series of rollers carrying an endless band, and asprin-g-driven chain of gear-wheels, a cam, a cam-operated lever, a weighted triplever, a set of catch-arms-and their shaft, a gear-wheel having a catch-pin, a sin gle-toothed ratchet-wheel, and a shaft, whereby the band will be moved automatically through fixed distances at regular intervals, as will be hereinafter fully described.

In the accom panyin g drawings, Arepresents the case or frame of the apparatus, to suitable supports in the upper part of which is attached a clock-work, B. The clock-work B is made in the ordinary manner, except that one of the shafts is provided with a cam, G. I prefer to attach the cam O to a shaft revolving once a minute; but it can be attached to a shaft having a faster or a slower movement, as may be required. The. clock-work B is designed to be provided with a dial, D, a minute-hand, E, and an hour-hand, F, in the ordinary manner.

G is a lever, which is pivoted to the frame of the clock-work B, or some other suitable support, in such a position that the inner end of the said lever will be struck and operated by the cam O at each revolution of the cam. The outer arm of the lever G passes beneath the outer arm of a lever, H, which is pivoted to the frame I. The inner arm of the leverH isbent to one side in such a position that when the outer arm of the said lever H is raised the end of the inner arm will be moved inward, so

as to receive a pi J, attached to a wheel, K, pivoted to the frame I, and thus stop the movement of.the said wheel K. The outer end -of the leverH is made heavy, or has a weight, L, attached to it, so that the said outer end, when released by the descent of the outer arm of the lever G, will drop and withdraw the inner end of the said lever from the pin J, allowing the wheel'K to revolve. I

To the outer part of the frame I is pivoted a shaft, M, to which is rigidly attached an arm, N. The arm N projects upward, is bent inward, is then bent to one side, and its end passes across the upper side of the weighted arm of the lever H, so that the arm N will be raised by raising the said weighted arm of the lever H.

To one end of the shaft M isrigidl y attached an arm, 0, which projects inward, and has its inner end bent down ward into hook form to engage with the pin J of the wheel K, and thus stop the said wheel. To the other end of the shaft M is rigidly attached an arm, P, which projects inward, and has a hook: formed upon its inner end to engage with the single-toothed ratchet-wheel Q, attached to the shaft It. The catch-arm P is made heavy, so that whenthe trip-arm N is released by the descent of the weighted arm of the lever H the weight of the said catch-arm P will turn the shaft Maud lower the catch-arm 0 into position to engage with the pin J of the wheel K and lower the said catch-arm P upon the ratchet-wheel Q, ready to engage with the tooth of the said ratchetwheel. The shaft R is connected by a chain of gear-wheels, S, with the stopand trip-wheel K, and with a coiled spring, T, connected with the frame I. The shaft of the spring T is connected with it s gear-wheel by a pawl and ratchet in the ordinary manner, so that the said shaft can be turned to wind up the spring T without turning the gear-wheels S. .The shaft R revolves in hearings in the case or frame A, and is extended beneath the clock-work B.

To the extended part of the shaft R is attached aroller or drum, U, around which passes an endless apron or band, V. The band V also.

passes around five drums or rollers, W, more or less, as the desired length of the band V may IOC require. Upon the band V is designed to be printed or otherwise formed a series of advertisements, which are designed to be exhibited, one at a time and successively, through a glass plate, X, secured in an opening in the lowerpart of the front of the case A.

With this construction, as the cam 0 comes. in contact with the lever G it raises the outer end of the said lever G and the weighted end of the lever H, bringing the inner end of the said lever H into position to receive the pin J of the wheel K. The upward movement of the lever H raises the catch-arms O and P out of gear and holds the said arms raised until the spring '1. has turned the wheel K so far as to bring the pin J in contact with the end of the lever H and has turned the shaft B so far that the hook of the catch-arm P has been carried past the tooth of the ratchet-wheel Q. As the lever G is released from the cam O the weighted end of the lever H withdraws the inner end of the said lever from the pin J and allows the wheel K and the shaft It to be revolved by the spring T, the end of the catcharm Priding upon the ratchet-wheel Q, ready to engage with the tooth of the said ratchetwheel Q when the shaft R has completed a revolution. The roller U, that drives the band V, is so arranged in size that one revolution of the shalt R and roller U will move the hand V sufficiently far to carry one advertisement out of sight and bring the next one into View.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1 An advertising apparatusconstructed substantiall y as herein shownand described, consisting of the clock-work B, the series of rollers U W, carrying an endless band, V, the springdriven chain of gear-wheels S, the cam O, the lever G, the weighted catch-lever H, the arm N, the trip-arms O P and their shaft M, the gear-wheel K, having pin J, and the singletoothecl ratchet-wheel Q, as set forth.
